and receiving a channel related to the beam failure recovery BFR through a first carrier wave in a first period, wherein the first period is a period when the network equipment is in a cell Discontinuous Reception (DRX) state and does not receive an uplink channel.

In view of the above, when the network device uses the cell DRX mechanism, the BFR procedure is affected if the network device cannot receive the BFR-related channel in the first period according to the configuration information of the cell DRX.

In the above embodiment, when the network device uses the cell DRX mechanism, for the channel related to the BFR, the configuration information of the cell DRX is not adhered to in the first period, but the channel related to the BFR is still received in the first period, so that the use of the cell DRX mechanism does not affect the normal operation of the BFR process, and the timely recovery of the beam failure of the terminal is ensured, and the data transmission performance of the terminal is ensured.

With reference to some embodiments of the first aspect, in some embodiments, the first carrier corresponds to a primary cell; or the first carrier corresponds to a primary and secondary cell; or the first carrier corresponds to a secondary cell.

In the above embodiment, it may be ensured that the use of the cell DRX mechanism does not affect the normal BFR procedure in different types of cells.

With reference to some embodiments of the first aspect, in some embodiments, the BFR-related channel includes at least one of:

a physical random access channel (physical random access channel, PRACH) for BFR;

scheduling requests (Scheduling request, SR) for BFR;

PUSCH for carrying BFR medium access control elements (medium access control controlelement, MAC CE).

and configuring a authorized physical uplink shared channel CG-PUSCH by a second configuration, wherein the second CG-PUSCH is activated after the terminal transmits a scheduling request for BFR.

In the above embodiment, it may be ensured that the use of the cell DRX mechanism does not affect the PUSCH transmission for carrying the BFR MAC CE sent by the terminal under different conditions in the BFR process.

With reference to some embodiments of the first aspect, in some embodiments, the method further includes:

and receiving the scheduling request for BFR through a second carrier, wherein the second carrier is the same as or different from the first carrier.

Herein, a primary cell (Pcell) and a primary secondary cell (primary secondary cell, PScell) may be collectively referred to as a special cell (speccell).

In an embodiment of the disclosure, a network device may configure a first resource on a spcell, and recover a search space (recovery search space), wherein the first resource may be at least one of: PRACH resources for BFR, SR resources for BFR.

The beam recovery method for the spcell may include:

after the terminal detects the beam failure on the spcell, the terminal sends the channel on the first resource to the network equipment through the first resource, so as to inform the network equipment that the terminal has the beam failure. The terminal listens for DCI in a recovery search space (recovery search space) in a time window after a preset duration, the time window corresponding to a BFR timer (beam failure recovery timer), the DCI indicating a time-frequency resource location of a scheduled first PUSCH. And the terminal transmits a BFR MAC CE on the first PUSCH, wherein the BFR MAC CE comprises a reference signal pilot frequency corresponding to a new wave beam for BFR.

In the embodiment of the disclosure, the network device may configure a second resource on the spcell, where the second resource corresponds to an SR for the BFR.

The beam recovery approach to Scell may be one of three approaches:

in the first way, after detecting the beam failure on the Scell, the terminal sends an SR for BFR to the network device through the second resource, and receives DCI sent by the network device, where the DCI indicates a time-frequency resource location of the scheduled first PUSCH. And the terminal transmits the second PUSCH, wherein the second PUSCH carries BFR MAC CE which contains reference signal pilot frequency corresponding to the new wave beam for BFR. Wherein, the DCI or the second PUSCH may correspond to any carrier.

In a second mode, after detecting beam failure on the Scell, the terminal sends an SR for BFR to the network device through the second resource, obtains a first CG-PUSCH resource configured by the network device, sends the first CG-PUSCH, and the first CG-PUSCH carries a BFR MAC CE, where the BFR MAC CE includes a reference signal pilot corresponding to a new beam for BFR. Wherein the first CG-PUSCH may correspond to any carrier.

In a third mode, after detecting beam failure on the Scell, the terminal sends an SR for BFR to the network device through the second resource, receives activation information sent by the network device, where the activation information indicates to activate the configured second CG-PUSCH, sends the second CG-PUSCH, and the second CG-PUSCH carries a BFR MAC CE, where the BFR MAC CE includes a reference signal pilot corresponding to a new beam for BFR. Wherein the second CG-PUSCH may correspond to any carrier.

In the above various modes, when the corresponding resource occupation amount of the PUSCH (including the first PUSCH, the second PUSCH, the first CG-PUSCH, and the second CG-PUSCH) carrying the BFR MAC CE is larger, the BFR MAC CE is a conventional BFR MAC CE, and when the corresponding resource occupation amount is smaller, the BFR MAC CE is a reduced (counted) BFR MAC CE.

In step S6102, the network device 102 terminates the cell DTX-off period on the first carrier.

After terminating the cell DTX-off period on the first carrier, the network device 102 may normally receive various uplink channels, so that it may receive various uplink channels that the terminal normally transmits.

In some embodiments, at least one of steps S6101 to S6102 may be performed. For example, step S6101 may be implemented as a separate embodiment; but is not limited thereto.

The following is described by way of several examples.

Example 1:

the PRACH for BFR is configured on the first carrier and the network device 102 is still listening for the PRACH for BFR on the first carrier during the first carrier is in cell DTX-OFF.

Example 2:

the SR for BFR is configured on the first carrier and the network device 102 is still listening for the SR for BFR on the first carrier during the time the first carrier is in cell DTX-OFF.

Example 3:

the network device 102 transmits DCI on the BFR search space, which schedules PUSCH on the first carrier.

The network device 102 is still to receive the PUSCH on the first carrier during the time the first carrier is in cell DTX-OFF.

Wherein the BFR search space is on a second carrier, which may be the same or different from the first carrier.

Example 4:

the terminal 101 has transmitted an SR for BFR on the second carrier, received a scheduling DCI on the third carrier, which schedules a PUSCH on the first carrier, which PUSCH is during cell DTX-OFF of the first carrier.

Alternatively, when the BFR-related channel is PRACH or SR, T may be equal to 0, since the time required for the network device to detect PRACH or SR is very short, which can be considered to be detected immediately.

Alternatively, when the BFR related channel is PUSCH or CG-PUSCH, T may be greater than 0, as the network device may take some time to demodulate PUSCH or CG-PUSCH.
