- the beam currently configured for the terminal for transmission and reception may have problems, that is, beam failure occurs.
- the current network equipment configured for the terminal to transmit and receive the physical downlink control channel (physical downlink control channel, PDCCH) transmit beam or receive beam may have problems, that is, the problem of beam failure.
- PDCCH physical downlink control channel
- the current standard defines that for the SCell, when the terminal detects beam failure on the SCell, the process of reporting beam failure is divided into two steps: First, the terminal is based on a similar physical uplink control channel-Scheduling Request (physical uplink control channel-Scheduling Request).
- PUCCH-SR PUCCH-SR signaling
- PUCCH-BFR requests a physical uplink shared channel (PUSCH) resource from a network device.
- the terminal uses the PUSCH resource allocated by the network device to send the index (index) of the SCell where the beam failure occurs in the form of a Medium Access Control (MAC) information element (CE).
- MAC Medium Access Control
- the terminal detects a new beam, while sending the index of the SCell where the beam failure occurred, the terminal sends the index of the new beam on the SCell detected by the terminal in the form of MAC CE.
- MAC Medium Access Control
- the embodiments of the present disclosure provide a BFR resource allocation method, which is applied to a terminal.
- the terminal is configured with multiple BFR resources.
- the multiple BFR resources are composed of PUCCH-BFR resources configured by serving cells in multiple serving cell groups configured by the terminal.
- the BFR resource allocation method provided by the embodiments of the present disclosure can also be understood as a PUCCH-BFR resource allocation method.
- the following takes the case where the terminal is configured with PCell/PScell, SCell#1, SCell#2, SCell#3, and SCell#4, and these serving cells are divided into two PUCCH groups as an example for description.
- PUCCH group1 includes PCell/PScell, SCell#1, SCell#2, and PUCCH-BFR1 is configured on PCell/PScell.
- PUCCH group2 includes SCell#3 and SCell#4, and PUCCH-BFR2 is configured in SCell#3.
- the SCell where the beam failure is detected in the terminal is an SCell that is not configured with PUCCH-BFR resources, for example, SCell#1, or SCell#2, or SCell#4.
- the PUCCH-BFR resource is not configured, the following priority may also be used to select the PUCCH-BFR resource.
- the PUCCH-BFR resource that appears first in time can be preferentially selected.
- the next available PUCCH-BFR resource is the PUCCH-BFR1 resource configured on PUCCH group1, then The terminal preferentially uses PUCCH-BFR1 resources.
- Fig. 3 is a flowchart showing a PUCCH-BFR resource allocation method according to an exemplary embodiment. As shown in Fig. 2, the PUCCH-BFR resource allocation method is used in a terminal and includes step S21, step S22, and step S23.
- the bit displays '1' to indicate beam failure, and displays '0' to indicate beam failure. It can also indicate the meaning of '0' and '1'. Swap.
- the high-bit bits correspond to SCell#4 with a small cell index
- the low-bit bits correspond to SCell#5 with a large cell index.
- the high bit bit corresponds to SCell#5 with a large cell index
- the low bit bit corresponds to SCell#4 with a small cell index.
- the MAC CE when the MAC CE indicates the index of the SCell where beam failure has occurred, it needs to indicate whether each SCell in all PUCCH groups configured by the terminal is beam failure. That is, the terminal needs to indicate in the MAC CE sent on the PUSCH resource requested by the PUCCH-BFR resource of the PCell/PSCell whether beam failure has occurred in each SCell in all SCells, and for the SCell that has beam failure, if it is detected The new beam must also indicate the corresponding new beam index.
- the terminal is configured with PCell/PScell, SCell#1, SCell#2, SCell#3, and SCell#4, then MAC CE targets SCell#1, SCell#2, SCell#3, and SCell#4 ,
- Each SCell has 1 bit to indicate whether the SCell has beam failure.
- the bit displays ‘1’ to indicate beam failure, and ‘0’ indicates that beam failure has not occurred.
- the meanings of ‘0’ and ‘1’ can be exchanged.
- the highest bit corresponds to the cell with the smallest index, namely SCell#1, and the lowest bit corresponds to the cell index. The largest is SCell#4.
- the PUCCH-BFR resource allocation method provided in the foregoing embodiment of the present disclosure realizes the determination of the PUCCH-BFR resource for sending the BFR by the terminal among multiple PUCCH-BFR resources. And when the terminal is configured with multiple PUCCH-BFRs, the PUCCH-BFR selection method during SCell beam failure is mainly to use the corresponding PUCCH-BFR through the PUCCH group. Only when the SCell configured with the PUCCH-BFR in the PUCCH group is also configured When beam failure occurs, the PUCCH-BFR configured on the PCell/PSCell is used, otherwise the PUCCH-BFR in the PUCCH group is used to reduce the MAC CE signaling overhead in step 2.
- the selecting unit 102 selects PUCCH-BFR resources configured by serving cells in another serving cell group different from the serving cell group to which the first Scell belongs.
