Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring a direct connection bandwidth part, and a storage medium.

Background

In a Long Term Evolution (LTE) 4G system, in order to support an Internet of things service, two major technologies of Machine Type Communication (MTC) and narrowband Internet of things (NB-IoT) are proposed. The two technologies mainly aim at low-speed, high-delay and other scenes. Such as meter reading, environmental monitoring, etc. NB-IoT is currently capable of supporting only a few hundred k of rates at maximum, MTC is currently capable of supporting only a few M of rates at maximum. With the continuous development of the internet of things services, such as video monitoring, smart home, wearable equipment, industrial sensing monitoring and other services, popularization is achieved. These services usually require a rate of several tens to 100M, and have relatively high requirements on delay, so MTC in the related art also makes it difficult for NB-IoT technology to meet the requirements. Therefore, a New terminal type is designed in a New 5G air interface (New Radio, NR) to cover the requirement of the middle-end internet of things device. In the current 3GPP standardization, this new terminal type is called low-capability terminal, sometimes also called Reduced capability UE, or called Redcap terminal, or NR-lite for short.

With the development of new generation 5G mobile communication technology, direct communication (sidelink communication) is also widely used. A sidelink function is introduced into the Redcap terminal, so that the use scene of the Redcap terminal is favorably expanded. For example, the Redcap terminal can directly exchange information through sidelink technology. In addition, the Redcap terminal uses sidelink, which can help the terminal relay information to the network equipment, enhance coverage and achieve the purpose of power saving.

However, in the sidelink configuration in the related art, a bandwidth part (BWP) is configured. The communication between sidelink terminals is performed in the sidelink BWP resource. The bandwidth of current sidelink BWPs may be greater than 20MHz under FR1 and greater than 100MHz under FR 2. However, for the Redcap terminal, due to the limited bandwidth capability, it is maximum 20MHz under FR1 and maximum 100MHz under FR 2. Therefore, based on the current sidelink BWP configuration scheme, the communication performance of the Redcap terminal will be limited.

The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The method for configuring the direct connection bandwidth part provided by the embodiment of the disclosure can be applied to the wireless communication system shown in fig. 1. Referring to fig. 1, in a scenario of performing direct connection communication between direct connection communication devices, a network device configures various transmission parameters for data transmission for the direct connection communication device 1. The direct connection communication device 1 serves as a data sending end, the direct connection communication device 2 serves as a data receiving end, and the two devices are in direct communication. The link for communication between the network device and the direct connection communication device is an uplink and downlink link, and the link between the direct connection communication device and the direct connection communication device is a direct connection link (Sidelink).

It is understood that the wireless communication system shown in fig. 1 is only a schematic illustration, and other network devices, such as a core network device, a wireless relay device, a wireless backhaul device, etc., may also be included in the wireless communication system, which is not shown in fig. 1. The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

It is further understood that the wireless communication system of the embodiments of the present disclosure is a network providing wireless communication functions. Wireless communication systems may employ different communication technologies, such as Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), single Carrier FDMA (SC-FDMA), Carrier Sense Multiple Access with Collision Avoidance (Carrier Sense Multiple Access). Networks can be classified into 2G (english: generation) networks, 3G networks, 4G networks or future evolution networks, such as 5G networks, according to factors such as capacity, rate and delay of different networks, and the 5G networks can also be referred to as New Radio Networks (NR). For ease of description, this disclosure will sometimes simply refer to a wireless communication network as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (eNB), a home base station, an Access Point (AP), a wireless relay node, a wireless backhaul node, a Transmission Point (TP), a Transmission and Reception Point (TRP) in a wireless fidelity (WIFI) system, and the like, and may also be a gNB in an NR system, or may also be a component or a part of a device constituting the base station. When a vehicle networking (V2X) communication system, the network device may also be a vehicle-mounted device. It should be understood that, in the embodiments of the present disclosure, the specific technology and the specific device form adopted by the network device are not limited.

Further, the Terminal referred to in this disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), and the like, and is a device that provides voice and/or data connectivity to a User, for example, the Terminal may be a handheld device having a wireless connection function, a vehicle-mounted device, and the like. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a Pocket Computer (PPC), a palm top Computer, a Personal Digital Assistant (PDA), a notebook Computer, a tablet Computer, a wearable device, or a vehicle-mounted device, etc. Furthermore, when being a communication system of the internet of vehicles (V2X), the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technologies and the specific device forms adopted by the terminal.

In the present disclosure, the communication scenario for direct communication between direct connection communication devices may also be a terminal-to-terminal (Device to Device, D2D) communication scenario. The direct communication device performing direct communication in the embodiments of the present disclosure may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, which have wireless communication functions, and various forms of User Equipment (UE), Mobile Stations (MS), terminals (Terminal), Terminal devices (Terminal Equipment), and the like. For convenience of description, the following embodiments of the present disclosure take a direct connection communication device as an example for explanation.

The terminal related to the embodiments of the present disclosure may be understood as a new type terminal designed in 5G NR: a low power terminal. Low-capability terminals are sometimes also referred to as Reduced capability UEs, or as Redcap terminals, or simply NR-lite. In the embodiment of the present disclosure, this new terminal is referred to as a Redcap terminal.

Similar to Internet of things (IoT) devices in Long Term Evolution (LTE), 5G NR-lite generally needs to satisfy the following requirements:

low cost, low complexity

A certain degree of coverage enhancement

-power saving

Since the current NR system is designed for high-end terminals with high speed, low delay and the like, the current design cannot meet the above requirement of NR-lite. There is therefore a need to adapt current NR systems to meet the requirements of NR-lite. For example, to meet the requirements of low cost and low complexity, the Radio Frequency (RF) bandwidth of NR-IoT may be limited, for example, to 5 mhz or 10 mhz, or the size of the buffer of NR-lite may be limited, so as to limit the size of the transport block received each time, and so on. For power saving, the possible optimization direction is to simplify the communication flow, reduce the number of times that the NR-lite terminal detects the downlink control channel, and the like.

In the related art, a sidelink function is introduced into a Redcap terminal. However, in the current sidelink configuration, one sidelink BWP is uniformly configured. Wherein, the bandwidth of sidelink BWP can be more than 20MHz under FR1, and can be more than 100MHz under FR 2. However, for the Redcap terminal, due to its limited bandwidth capability, it is maximum 20MHz under FR1 and maximum 100MHz under FR 2. Therefore, limited by the bandwidth capability of the Redcap terminal, the unified configuration of sidelink BWP will limit the communication performance of the Redcap terminal. Based on the current sidelink BWP configuration scheme, if a Redcap terminal is introduced, the possible sidelink BWP configuration schemes may be the following two schemes:

the first scheme is as follows: the bandwidth of the sidelink BWP is limited to be within the capability of Redcap.

However, limiting the bandwidth of sidelink BWP to within the capability of Redcap has a significant impact on the communication system and normal terminals (non-Redcap terminals), such as limiting the rate of interaction and flexibility of network configuration.

Scheme II: flexible deployment of sidelink BWP.

However, flexibly configuring the sidelink BWP may cause the bandwidth range of the flexibly configured sidelink BWP to exceed the capability of the Redcap terminal, so that the Redcap terminal may not be able to monitor the entire sidelink BWP, thereby causing a barrier to interaction with the Redcap terminal.

In view of this, the embodiments of the present disclosure provide a sidelink BWP configuration method. In the sidelink BWP configuration method, a plurality of sidelink BWPs are determined, and one sidelink BWP is configured relatively uniformly, so that the possibility that a sidelink communication system is compatible with a Redcap terminal can be improved, and the performance of the communication system is further improved.

Fig. 2 is a flowchart illustrating a sidelink BWP configuration method according to an example embodiment. The sidelink BWP configuration method may be performed alone or in combination with other embodiments of the present disclosure. As shown in fig. 2, the sidelink BWP configuration method is used in the first terminal and includes the following steps.

In step S11, sidelink BWP configuration information indicating a plurality of sidelink BWPs is determined.

In the embodiment of the disclosure, configuration of multiple sidelink BWPs in a sidelink communication system is supported, and the sidelink BWPs may have different bandwidth capabilities, so that terminals adapted to different capability types perform sidelink communication based on the sidelink BWPs adapted to their own bandwidth capabilities. For example, a sidelink BWP capable of supporting the bandwidth capability of a Redcap terminal may be determined among a plurality of sidelink BWPs, such that the Redcap terminal is capable of sidelink communication in the sidelink BWP suitable for the Redcap terminal.

In the sidelink BWP configuration method provided in the embodiment of the present disclosure, different sidelink BWPs may be configured based on different bandwidth capabilities of different types of terminals.

Wherein different types of terminals may have different capabilities. For example, the capability of the terminal may be a transceiving bandwidth, the number of transceiving antennas, the maximum number of bits of a transport block, and a processing time delay, etc. The difference in the capabilities of the terminals may be one or more of a difference in transceiving bandwidth, a difference in the number of transceiving antennas, a maximum number of bits of a transport block, and a difference in processing time delay.

For convenience of description, any two different types of terminals among different types of terminals may be referred to as a first type of terminal and a second type of terminal in the embodiments of the present disclosure.

The first type terminal and the second type terminal in the embodiments of the present disclosure may have different capabilities. For example, the capability of the terminal may be a transceiving bandwidth, the number of transceiving antennas, the maximum number of bits of a transport block, and a processing time delay, etc. The difference in the capabilities of the terminals may be one or more of a difference in transceiving bandwidth, a difference in the number of transceiving antennas, a maximum number of bits of a transport block, and a difference in processing time delay.

The sidelink BWP configured for the first type of terminal is referred to as a first sidelink BWP. The sidelink BWP configured for the second type terminal is referred to as a second sidelink BWP.

In an implementation manner, in the sidelink BWP configuration method provided in the embodiment of the present disclosure, at least one first sidelink BWP is included in the plurality of sidelink BWPs indicated in the sidelink BWP configuration information. The first sidelink BWP belongs to the bandwidth capability range of the first type of terminal. The bandwidth capability range of the first type terminal may be, for example, 20MHz maximum under FR1, and 100MHz maximum under FR 2.

Fig. 3 is a flowchart illustrating a sidelink BWP configuration method according to an exemplary embodiment, which may be implemented alone or in combination with other embodiments of the present disclosure. As shown in fig. 3, the sidelink BWP configuration method is used in the first terminal and includes the following steps.

In step S21, sidelink BWP configuration information indicating a plurality of sidelink BWPs including at least one first sidelink BWP, where the first sidelink BWP belongs to the bandwidth capability range of the first type terminal, is determined.

In another embodiment, in the sidelink BWP configuration method provided in the embodiment of the present disclosure, the plurality of sidelink BWPs indicated in the sidelink BWP configuration information includes at least one second sidelink BWP. The second sidelink BWP belongs to the bandwidth capability range of the second type of terminal.

Fig. 4 is a flowchart illustrating a sidelink BWP configuration method according to an exemplary embodiment, which may be implemented alone or in combination with other embodiments of the present disclosure. As shown in fig. 3, the sidelink BWP configuration method is used in the first terminal and includes the following steps.

In step S31, sidelink BWP configuration information indicating a plurality of sidelink BWPs including at least one second sidelink BWP, where the second sidelink BWP belongs to the bandwidth capability range of the second type terminal, is determined.

In the sidelink BWP configuration method provided by the embodiment of the present disclosure, the first type terminal and the second type terminal have different capabilities, and the capability of the second type terminal is greater than that of the first type terminal. For example, in one example, the first type of terminal may be a Redcap terminal and the second type of terminal may be an NR terminal (non-Redcap terminal).

In one example, the first type of terminal is a Redcap terminal. In the embodiment of the present disclosure, at least one sidelink BWP included in the sidelink BWP configuration information is within the bandwidth capability range of the Redcap terminal, so as to be used by the Redcap terminal.

In another example, the second type terminal is an NR terminal. In the embodiment of the present disclosure, at least one sidelink BWP included in the plurality of sidelink BWPs indicated in the sidelink BWP configuration information is within the bandwidth capability range of the NR terminal, so as to be used by the NR terminal.

In the sidelink BWP configuration method provided in the embodiment of the present disclosure, the sidelink BWP may be configured based on the system information. The terminal may determine sidelink BWP configuration information based on the system information.
