Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for transmitting and receiving antenna information.

Background

With the development of mobile communication technology, people's production and life have changed greatly. The first generation communication system adopts the simulation technology and the frequency division multiple access technology to realize mobile two-way communication; the second generation communication system adopts digital time division multiple access technology and code division multiple access technology to improve the conversation quality of the first generation communication system and realize low-speed data transmission; the third generation communication system and the fourth generation communication system which are appeared together not only improve the conversation quality of the voice service, but also improve the data transmission speed.

In the third generation communication system and the fourth generation communication system, a Multiple-Input Multiple-Output (MIMO) technology is used.

The basic feature of MIMO technology is the use of multiple transmit antennas and multiple receive antennas. Specifically, the MIMO technology regards multipath wireless communication as a whole with transmission and reception, and one way is: increasing the spatial dimension of data multiplexing to ensure that a plurality of data are spatially multiplexed to the same time-frequency resource; the other mode is as follows: the same data is transmitted on multiple transmit antennas and/or received with multiple receive antennas, resulting in a diversity gain of the control. In this way, MIMO technology increases channel capacity without increasing bandwidth, thereby achieving high communication capacity and high spectrum resource utilization.

However, the channel capacity linearly increases with the number of antennas, and in order to meet the requirement of the MIMO technology, the number of antennas configured in the terminal device is also increased from the original 1 antenna to 4 antennas, or even more. Since the terminal device side also uses multiple antennas to transmit or receive data, not only the computational complexity is increased compared to Single Input Single Output (SISO) when estimating the number of channels for transmitting data, but also the complexity of selecting channels for data transmission with the terminal device by the base station is increased due to the increase of the number of antennas at the terminal device side, and how to acquire the antenna information of the terminal device in time becomes a problem that needs to be solved urgently.

Detailed Description

In order to achieve the object of the present invention, embodiments of the present invention provide a method and a device for sending and receiving antenna information, where first antenna information of a terminal device is obtained, where the first antenna information includes at least one of a maximum uplink number supported by the terminal device, a number of antennas supported by the terminal device, and whether the terminal device supports a switch antenna; and sending the first antenna information to the base station, so that the terminal device can control the antenna deployed by the terminal device according to the service requirement of the terminal device and report the antenna information of the terminal device to the base station in time.

It should be noted that the present application will be described in conjunction with a terminal device and/or a base station.

The terminal device may be a wireless terminal or a wired terminal, and the wireless terminal may be a communication device providing a voice service and/or a data service, a handheld device having a wireless connection function, a wearable device, or another processing device connected to the wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal, for example, a portable, pocket, hand-held, wearable, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDA). A wireless Terminal may also be referred to as a system, a Subscriber Unit (abbreviated SU), a Subscriber Station (abbreviated SS), a Mobile Station (abbreviated MB), a Mobile Station (Mobile Station), a Remote Station (abbreviated RS), an access point (abbreviated AP), a Remote Terminal (abbreviated RT), an access Terminal (abbreviated AT), an AT, a User Terminal (abbreviated UT), a User agent (User agent; abbreviated UA), a Terminal Device (User Device; abbreviated UD), or a User equipment (abbreviated UE).

A base station (e.g., access point) can refer to a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals. The base station may be configured to interconvert received air frames and IP packets as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) network. The base station may also coordinate management of attributes for the air interface. For example, the Base Station may be a Base Transceiver Station (BTS) in GSM or CDMA, a Base Station (NodeB) in WCDMA, or an evolved node B (NodeB or eNB or e-NodeB) in LTE, and the present application is not limited thereto.

In addition, the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the prior art, the terminal equipment cannot transmit the antenna information to the base station, on one hand, the terminal equipment does not need to transmit the antenna information to the base station due to the limited number of antennas on the terminal equipment, on the other hand, no mode exists for the terminal equipment to transmit the antenna information to the base station, and when the base station schedules the terminal equipment along with the increase of the number of antennas on the terminal equipment side, because the current antenna information at the terminal equipment side is not known, the scheduling resources can not be well configured for the terminal equipment, so that the communication quality between the base station and the terminal equipment can not be ensured, therefore, in order to ensure the quality of data transmission between the base station and the terminal equipment, the base station needs to acquire the antenna information of the base station, and determining the resource for communicating with the terminal equipment according to the antenna information, thereby reasonably scheduling the channel resource for the communication service initiated by the terminal equipment and improving the communication capability between the terminal equipment and the base station.

The following detailed description of various embodiments of the invention refers to the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
