Technical Field

The invention relates to the technical field of mobile communication, in particular to an information receiving method, an information sending method and equipment.

Background

In the prior art, the bandwidth supported by the terminal and the bandwidth supported by the base station may be different, and the bandwidths supported by different terminals may also be different. The base station usually broadcasts bandwidth in the system message of the cell, and if a certain terminal does not support the bandwidth broadcasted by the cell, the terminal cannot access the cell. In addition, after the terminal enters the connected state, the terminal usually reports the bandwidth capability supported by the terminal, and the cell can configure the bandwidth meeting the terminal capability for the terminal by using a dedicated signaling according to the bandwidth capability.

The prior art has the defect that the frequency spectrum resources are difficult to be fully utilized. For example, an operator has a carrier with a bandwidth of 9MHz, and there are two terminals in the network, one supporting only 5MHz, and the other supporting 5MHz and 9 MHz. According to the prior art, if 9MHz is broadcasted in a cell system message, a terminal supporting 5MHz will not be able to access the cell, and therefore the cell needs to broadcast 5 MHz. Then, according to the above scheme, approximately 50% of spectrum resources cannot be used by the idle terminal, and all system messages and paging can only be sent within 5MHz, thereby causing the spectrum resources to be underutilized.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies).

For example, each communication link may be a multi-carrier signal modulated according to various radio technologies.

Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

As described in the background art, in the manner of broadcasting cell bandwidth in the prior art, there is a problem that spectrum resources of a cell are difficult to be fully utilized, and to solve at least one of the above problems, embodiments of the present invention provide an information receiving method, which can improve flexibility of bandwidth resource indication and utilization rate of bandwidth resources.

Referring to fig. 2, an information receiving method provided in an embodiment of the present invention, when applied to a terminal side in an idle state or an inactive state, includes:

step 21, receiving initial bandwidth part information of a cell, where the initial bandwidth part information includes at least two bandwidths.

Here, a network (e.g., a base station) may broadcast initial Bandwidth Part (BWP) information of a transmitting cell, the initial Bandwidth Part information including at least two bandwidths. The terminal in an idle state or an inactive state may receive the initial bandwidth part information. In addition, the initial bandwidth part information may further include frequency domain positions of the respective bandwidths to indicate specific positions of the frequency domain resources of the respective bandwidths. More specifically, the at least two bandwidths may correspond to the same subcarrier spacing.

And step 22, determining the cell as a cell which is forbidden to be accessed or a candidate cell according to the initial bandwidth part information.

Here, in the case where the bandwidth supported by the terminal is smaller than all the bandwidths in the initial bandwidth part information, it is determined that the cell is prohibited from accessing, and at this time, the terminal does not take the cell as a candidate cell and thus does not access the cell. And when the bandwidth supported by the terminal is greater than or equal to any bandwidth in the initial bandwidth part information, determining the cell as a candidate cell, and at this time, the terminal can access the cell.

Through the above steps, the embodiment of the present invention broadcasts at least two bandwidths of the cell through the cell, and the terminal determines whether the cell can be used as a candidate cell according to whether the bandwidth supported by the terminal is greater than or equal to any bandwidth of the cell. In addition, because the initial bandwidth part information comprises at least two bandwidths, the terminal can more easily take the cell as a candidate cell and select a proper bandwidth for subsequent access, and the utilization rate of the idle state or the inactive state terminal on the bandwidth resource can be improved.

According to some embodiments of the present invention, the network may further send the indication information of the carrier bandwidth of the cell, and the terminal may receive the indication information of the carrier bandwidth of the cell sent by the network, so as to determine the carrier bandwidth of the cell.

According to some embodiments of the present invention, the terminal may further determine the channel bandwidth in the following manner:

selecting the maximum bandwidth from the first type of bandwidths as a first candidate bandwidth; and selecting the maximum bandwidth from the second type of bandwidth as a second candidate bandwidth. Then, taking the first candidate bandwidth as the channel bandwidth of the terminal under the condition that the first candidate bandwidth is larger than the second candidate bandwidth; and taking the first candidate bandwidth or the second candidate bandwidth as the channel bandwidth of the terminal under the condition that the first candidate bandwidth is smaller than the second candidate bandwidth.

Here, the first type of bandwidth is an intersection of a third type of bandwidth and a bandwidth in the initial bandwidth part information, and the second type of bandwidth is a difference set of the third type of bandwidth and the first type of bandwidth; the third type of bandwidth is a bandwidth which is less than or equal to the carrier bandwidth of the cell and is greater than or equal to the minimum bandwidth in the initial bandwidth part information, among the bandwidths supported by the terminal.

After determining the channel bandwidth, the terminal may further select a fourth type of bandwidth that is less than or equal to the channel bandwidth from the bandwidths in the initial bandwidth part information, and determine a maximum bandwidth in the fourth type of bandwidth as the initial bandwidth part bandwidth of the terminal. In this way, the terminal can receive the paging message sent by the cell on the initial bandwidth part bandwidth of the terminal. In addition, in the embodiment of the present invention, the terminal may receive a system message of a cell on a minimum bandwidth in the initial bandwidth part information. Through the steps, the terminal of the embodiment of the invention can select the proper bandwidth to receive the paging message and/or the system message, thereby improving the utilization rate of the bandwidth resource by the idle state or the inactive state terminal.

It should be noted that, at least two bandwidths included in the initial bandwidth part information in step 21 above, where the at least two bandwidths correspond to an uplink bandwidth, a downlink bandwidth, or an uplink and downlink bandwidth. That is, the at least two bandwidths may be bandwidths in the uplink bandwidth, may also be bandwidths in the downlink bandwidth, and may be bandwidths included in both the uplink bandwidth and the downlink bandwidth.

In addition, in the embodiment of the present invention, the terminal may further send, to the network, indication information of a bandwidth supported by the terminal, so that the network determines a channel bandwidth or an initial bandwidth part bandwidth of the terminal.

The method according to the embodiment of the present invention is explained above from the terminal side, and is explained further below from the network device side.

Referring to fig. 3, an embodiment of the present invention provides an information sending method, which is applied to a first network device, where the device may specifically be a base station, and as shown in fig. 3, the method includes:

step 31, sending initial bandwidth part information of a cell, where the initial bandwidth part information includes at least two bandwidths, and is used for a terminal in an idle state or an inactive state to determine that the cell is a cell prohibited from accessing or a candidate cell.

Here, the at least two bandwidths correspond to the same subcarrier spacing. In addition, the at least two bandwidths may correspond to an uplink bandwidth, a downlink bandwidth, or an uplink and downlink bandwidth. The initial bandwidth part information may further include a frequency domain position of each bandwidth to indicate a specific position of the frequency domain resource of the corresponding bandwidth.

Through the steps, the network sends at least two bandwidths of the cell, so that the terminal can flexibly select a proper bandwidth to receive the paging message or the system message, and the flexibility of bandwidth resource indication can be improved.

In addition, in the embodiment of the present invention, the first network device may further send information of the carrier bandwidth of the cell, so that the terminal may determine the channel bandwidth of the terminal according to the carrier bandwidth of the cell. The first network device may further transmit a system message of the cell on a minimum bandwidth in the initial bandwidth part information so that as many terminals as possible can receive the system message.

Similar to the implementation manner of the terminal side, in the embodiment of the present invention, the first network device may further select a maximum bandwidth from the first type of bandwidths, as a first candidate bandwidth; selecting the maximum bandwidth from the second type of bandwidth as a second candidate bandwidth; then, taking the first candidate bandwidth as the channel bandwidth of the terminal under the condition that the first candidate bandwidth is larger than the second candidate bandwidth; and taking the first candidate bandwidth or the second candidate bandwidth as the channel bandwidth of the terminal under the condition that the first candidate bandwidth is smaller than the second candidate bandwidth. Here, the first type of bandwidth is an intersection of a third type of bandwidth and a bandwidth in the initial bandwidth part information, and the second type of bandwidth is a difference set of the third type of bandwidth and the first type of bandwidth; the third type of bandwidth is a bandwidth which is less than or equal to the carrier bandwidth of the cell and is greater than or equal to the minimum bandwidth in the initial bandwidth part information, among the bandwidths supported by the terminal.

Specifically, the first network device may obtain the bandwidth supported by the terminal through at least one of the following manners:

1) and receiving the information of the bandwidth supported by the terminal, which is sent by the terminal, so as to obtain the bandwidth supported by the terminal.

2) Receiving a paging request aiming at the terminal and sent by a second network device, wherein the paging request carries capability information of the terminal, and the capability information comprises a bandwidth supported by the terminal.

In the case that a paging message needs to be sent to the terminal, the first network device may further select a fourth type bandwidth that is less than or equal to the channel bandwidth from the bandwidths in the initial bandwidth part information, and determine a maximum bandwidth in the fourth type bandwidth as the initial bandwidth part bandwidth of the terminal.
