In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

To facilitate a better understanding of embodiments of the present application, a Multi-beam (Multi-beam) system related to the present application is described.

Design goals for NR systems include large bandwidth communications in high frequency bands (e.g., bands above 6 GHz). As the operating frequency becomes higher, the path loss during transmission increases, thereby affecting the coverage capability of the high frequency system. In order to effectively ensure the coverage of the high-frequency range NR system, an effective technical scheme is based on a large-scale antenna array (Massive MIMO) to form a shaped beam with larger gain, overcome propagation loss and ensure the coverage of the system.

The millimeter wave antenna array has the advantages that due to the fact that the wavelength is shorter, the antenna array interval and the aperture are smaller, more physical antenna arrays can be integrated in a two-dimensional antenna array with a limited size, meanwhile, due to the fact that the size of the millimeter wave antenna array is limited, a digital wave beam forming mode cannot be adopted in consideration of factors such as hardware complexity, cost overhead and power consumption, an analog wave beam forming mode is adopted generally, network coverage is enhanced, and meanwhile the realization complexity of equipment can be reduced.

In a 2G/3G/4G system, one cell (sector) uses one wider beam (beam) to cover the entire cell. So at each moment, the UE in the coverage of the cell has an opportunity to acquire the transmission resources allocated by the system.

The NR Multi-beam system covers the whole cell by different beams, i.e. each beam covers a smaller area, and the effect of multiple beams covering the whole cell is achieved by a temporal sweep.

For example, different synchronization signals/physical broadcast channel blocks (synchronization signal/physical broadcast channel block, SS/PBCH block, or SSB) are transmitted on different beams, which the UE can distinguish from.

For another example, different channel state information reference signals (Channel State Information Reference Signal, CSI-RS) are transmitted on different beams, and the UE identifies the different beams by CSI-RS signals/CSI-RS resources.

In one multi-beam system, the physical downlink control channel (Physical Downlink Control Channel, PDCCH) and the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) may be transmitted over different downlink transmit beams.

For better understanding of the embodiments of the present application, CSI reporting related to the present application is described.

In order for the network device to perform reasonable scheduling, the terminal device needs to feed back CSI so that the network device determines scheduling information of the terminal device such as the number of transmission layers, the precoding matrix, the transmission beam, the modulation coding mode and the like. Specifically, CSI reporting by the terminal device is performed based on CSI reporting configuration indicated by the network device. Each CSI reporting configuration corresponds to one CSI report, and which contents contained in the CSI are determined by reporting quality information (reporting quality) in the CSI reporting configuration. For example, the CSI reporting amount may be configured to include indication information of a reference signal (or beam) selected by the terminal device and/or a measurement result of the reference signal (or beam) selected by the terminal device.

In some embodiments, the Reference signals may include, for example, but not limited to, a synchronization Signal block (Synchronization Signal Block, SSB), a channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS).

Note that SSB may also be referred to as a synchronization signal/physical broadcast channel block (synchronization signal/physical broadcast channel block, SS/PBCH block).

In some scenarios, the physical uplink control channel (Physical Uplink Control Channel, PUCCH) cell group (PUCCH Cell Groups, PUCCH CG) concept is introduced. For example, all aggregated cells may be divided into multiple PUCCH CG, where PUCCH CG including a special cell (SPCell) is referred to as a primary PUCCH cell group (Primary PUCCH group), other PUCCH CG is referred to as a secondary PUCCH cell group (Secondary PUCCH group), and a secondary cell (SCe 11) carrying PUCCH in the PUCCH CG is referred to as a PUCCH secondary cell (PUCCH SCe 11).

The SPcell may refer to a primary cell (PCell) or a primary secondary cell (PScell).

In the NR system, when an SCell activation command is received in the time slot n, then the terminal device may report, to the network device, channel state information (Channel State Information, CSI) reporting at the earliest time point in the time slot n+k, where the CSI reporting is used to report a reference signal with better signal quality to the network device. As shown in fig. 2, the terminal device may activate the SCell between the time slot n+k and the specified activation delay requirement, and further report the CSI report to the network device at the SCell.

But the premise that the terminal device can report the CSI report is that at least one of the serving cells in the PUCCH group to which the SCell belongs is active. When the SCell belongs to Secondary PUCCH group, the terminal device can send CSI reports only after the SCell in Secondary PUCCH group is activated, affecting network performance. Therefore, how to timely inform the network device of the reference signal with better signal quality is a problem to be solved.

Fig. 3 is a schematic flow chart of a method 200 of wireless communication according to an embodiment of the present application, the method 200 being executable by a terminal device in the communication system shown in fig. 1, as shown in fig. 3, the method 200 comprising:

S210, triggering beam failure recovery (beam failure recovery, BFR) for a first secondary cell when the terminal device receives a first signaling, where the first signaling is used to activate the first secondary cell, and the first secondary cell is a physical uplink control channel PUCCH secondary cell (i.e. PUCCH SCell).

In some embodiments of the present application, the first signaling activates a MAC CE (SCell) for the secondary cell

Activation/Deactivation MAC CE) that is used to activate the first secondary cell.

In other embodiments of the present application, the first signaling is radio resource control (Radio Resource Control, RRC) signaling, where the RRC signaling is used to configure the PUCCH secondary cell and the activation state of the PUCCH secondary cell.

For example, the RRC signaling may configure the first secondary cell as a PUCCH secondary cell, and configure an activated state parameter (sCellState) of the first secondary cell as activated to activate the first secondary cell.

In some embodiments of the present application, the first secondary cell belongs to a secondary PUCCH cell group, i.e. Secondary PUCCH group.

In some embodiments, before receiving the first signaling, the first secondary cell is not activated, or there is no PUCCH SCell activated in Secondary PUCCH group to which the first secondary cell belongs, and therefore, the terminal device cannot report the CSI report to the network device through the PUCCH SCell in Secondary PUCCH group. This is denoted as case 1.

In some embodiments of the present application, the method 200 further includes:

the terminal device sends a BFR media access control element, MAC CE, to the network device on a first serving cell, where the first serving cell belongs to a primary PUCCH cell group, primary PUCCH group.

Optionally, in the case that the first secondary cell is not activated, or none of the PUCCH scells in Secondary PUCCH group to which the first secondary cell belongs is activated, the terminal device may trigger a BFR for the first secondary cell through the serving cell in Primary PUCCH group. And reporting the information of the reference signal required to be reported in the CSI report to the network equipment through the triggered BFR.

In some embodiments, the BFR MAC CE includes at least one of:

information of the first secondary cell, identification information of at least one reference signal.

And the terminal equipment indicates to the network equipment that the BFR MAC CE transmitted by the first service cell is the BFR triggered for the first auxiliary cell by carrying the information of the first auxiliary cell in the BFR MAC CE.

In some embodiments, the BFR MAC CE may indicate the target cell triggering the BFR through a bit map (bitmap).

For example, the BFR MAC CE includes a first bitmap including a plurality of bits, each bit corresponding to a cell, the value of each bit being used to indicate whether the corresponding cell triggers a BFR, or the value of the plurality of bits being used to determine for which cell the BFR MAC CE triggers.

Fig. 4 shows a typical format of a BFR MAC CE, taking an example that a plurality of bits includes 8 bits, C7-C1 corresponds to 7 scells, SP corresponds to spcells, for example, a bit value of 0 indicates that the corresponding cell trigger BFR is not assumed, and a bit value of 1 indicates that the corresponding cell trigger BFR is assumed. If the value of C3 is 1, the value of 0 of other bits is indicated as SCell trigger BFR corresponding to C3.

In some embodiments, the at least one reference signal is a reference signal in a candidate reference signal list (candidateBeamRSSCellList), wherein the candidate reference signal list is preconfigured.

For example, the candidate reference signal list is sent by the network device to the terminal device through RRC signaling.

Optionally, the candidate reference signal list is sent to the terminal device before the first secondary cell is activated.

In some embodiments, the at least one reference signal is a reference signal in the candidate list of reference signals for which the signal quality meets a first threshold (e.g., is greater than the first threshold, or is greater than or equal to the first threshold).

Optionally, the first threshold is preconfigured.

Optionally, the first threshold is sent by the network device to the terminal device through RRC signaling.

Optionally, the first threshold is sent to the terminal device before the first secondary cell is activated.

Optionally, the signal quality of the at least one reference signal may be characterized by at least one of the following indicators: reference signal received power (Reference Signal Receiving Power, RSRP), reference signal received quality (Reference Signal Receiving Quality, RSRQ), signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR).

Correspondingly, the first threshold may be an RSRP threshold (or RSRP-threshold bfr), an RSRQ threshold, or an SINR threshold, etc.

Optionally, the signal quality of the at least one reference signal is characterized by measurements that are not filtered by the physical layer, such as layer 1-RSRP (L1-RSRP) or the like.

Fig. 4 illustrates a typical format of a BFR MAC CE, for example, the BFR MAC CE may include an identification of candidate reference signals in the candidate reference signal list that need to be reported.

In other embodiments, the terminal device may also indicate the candidate reference signal reported by the terminal device in a bitmap manner. For example, the BFR MAC CE includes a second bitmap, where the second bitmap includes a plurality of bits, each bit corresponds to one candidate reference signal in the candidate reference signal list, and a value of each bit is used to indicate whether the corresponding candidate reference signal meets the first threshold, or whether the terminal device reports the candidate reference signal. For example, a value of 1 indicates that the first threshold is met, and a value of 0 indicates that the first threshold is not met. Assuming that the candidate reference signal list includes 8 candidate reference signals (RS 8 to RS 1), if RS3 is a reference signal whose signal quality satisfies the first threshold, and the second bitmap includes B1 to B8 corresponding to RS8 to RS1, respectively, the second bitmap may be 00000100.

In some embodiments, the reference signals may include, for example, but not limited to, SSB, CSI-RS.

In other embodiments of the present application, the first secondary cell is activated before the first signaling is received, or there is an activated PUCCH SCell in Secondary PUCCH group to which the first secondary cell belongs. This is denoted as case 2.

the terminal device cancels the triggered BFR.

For example, when the first secondary cell is activated, or when there is an activated PUCCH SCell in Secondary PUCCH group to which the first secondary cell belongs, the terminal device cancels the triggered BFR.

Further, the method 200 further comprises:

the terminal equipment sends a CSI report to the network equipment on the first auxiliary cell, wherein the CSI report comprises identification information of at least one reference signal and/or signal quality information of the at least one reference signal; or alternatively

The terminal device sends a CSI report to the network device on a second secondary cell, where the CSI report includes identification information of at least one reference signal and/or signal quality information of the at least one reference signal, and the second secondary cell may be a PUCCH SCell activated in Secondary PUCCH group to which the first secondary cell belongs.

For example, in case a first secondary cell has been activated, a CSI report is sent to the network device on the first secondary cell.

For another example, in case the first secondary cell is not active, but the second secondary cell in Secondary PUCCH group to which the first secondary cell belongs is active, a CSI report is sent to the network device on the second secondary cell.

That is, in the foregoing case 2, the terminal device may not trigger the BFR for the first secondary cell, but report the CSI report to the network device on the first secondary cell or the PUCCH SCell activated in Secondary PUCCH group to which the first secondary cell belongs.

In summary, when the terminal device receives the activation signaling of the SCell, but the SCell is not yet activated, or the PUCCH SCell that is not activated in Secondary PUCCH group to which the SCell belongs, the BFR is triggered for the SCell to report the information of the reference signal that needs to be reported through the CSI report to the network device, without waiting for the information of the reference signal to be reported after the activation of the SCell, so that the network device can be guaranteed to timely acquire the information of the reference signal with better signal quality selected by the terminal device, and network performance is improved.

The method of wireless communication according to an embodiment of the present application is described above in detail from the perspective of the terminal device in conjunction with fig. 3 and 4, and the method of wireless communication according to another embodiment of the present application is described below in detail from the perspective of the network device in conjunction with fig. 5. It should be understood that the description on the network device side corresponds to the description on the terminal device side, and similar descriptions may be referred to above, and are not repeated here for avoiding repetition.

Fig. 5 is a schematic flow chart of a method 300 of wireless communication according to another embodiment of the present application, the method 300 being executable by a network device in the communication system shown in fig. 1, as shown in fig. 5, the method 300 comprising:

s320, the network equipment receives the beam failure recovery media access control element BFR MAC CE sent by the terminal equipment.

In this embodiment of the present application, the BFR MAC CE may be sent when the first secondary cell is not activated, or when there is no PUCCH SCell activated in Secondary PUCCH group to which the first secondary cell belongs.

In some embodiments of the present application, the S310 includes:

and receiving the BFR MAC CE sent by the terminal equipment on a first service cell, wherein the first service cell belongs to a main PUCCH cell group, namely Primary PUCCH group.

Optionally, in the case that the first secondary cell is not activated, or neither PUCCH SCell in Secondary PUCCH group to which the first secondary cell belongs is activated, the network device may receive, by the serving cell in Primary PUCCH group, a BFR triggered by the terminal device for the first secondary cell. And acquiring information of the reference signal reported by the CSI report through the triggered BFR.

In some embodiments, the BFR MAC CE includes at least one of:

In some embodiments, the at least one reference signal is a reference signal in a list of candidate reference signals, wherein the list of candidate reference signals is preconfigured.

Optionally, the first threshold is preconfigured.

Correspondingly, the first threshold may be an RSRP threshold, an RSRQ threshold, or an SINR threshold, etc.

In other embodiments, the terminal device may also indicate, by using a bitmap manner, the candidate reference signals reported by the terminal device, for example, the BFR MAC CE includes a second bitmap, where the second bitmap includes a plurality of bits, each bit corresponds to one candidate reference signal in the candidate reference signal list, and a value of each bit is used to indicate whether the corresponding candidate reference signal meets the first threshold, or whether the terminal device reports the candidate reference signal. For example, a value of 1 indicates that the first threshold is met, and a value of 0 indicates that the first threshold is not met. Assuming that the candidate reference signal list includes 8 candidate reference signals (RS 8 to RS 1), if RS3 is a reference signal whose signal quality satisfies the first threshold, and the second bitmap includes B1 to B8 corresponding to RS8 to RS1, respectively, the second bitmap may be 00000100.
