Description

Method and device for reporting beam failure

This application claims the priority of a Chinese patent application filed with the Chinese Patent Office, the application number is 201910363753.1, and the application name is "Method and Apparatus for Reporting Beam Failure" on April 30, 2019, the entire content of which is incorporated into this application by reference .

Technical field

This application relates to the field of communications, and more specifically, to a method and device for beam failure reporting.

Background technique

Communication between network equipment and terminals usually requires the use of analog beams to overcome high-frequency path loss, that is, to increase antenna gain. Generally speaking, an analog beam is directional. For example, a main lobe direction and a 3dB beam width are used to describe an analog beam pattern. The narrower the beam width, the greater the antenna gain. Network devices and terminals can send and receive signals in specific directions to achieve communication. Take the following communication as an example. The network device sends a signal in a specific direction, and the terminal receives a signal in a specific direction. Normal communication can only be realized when the sending and receiving directions are aligned. In order to achieve beam alignment (that is, the beam direction alignment of the transmitting end and the receiving end), beam training is required. When the communication beam is blocked, it is necessary to switch to a new beam for communication. This process can be called beam failure recovery.

In the traditional solution, the network device configures dedicated resources for the second cell to transmit beam failure recovery information. For example, the second cell is the primary cell (primary cell, Pcell). After the beam in the Pcell fails, the corresponding resource direction can be used. The network device sends beam failure recovery information, so that the failed beam can be recovered. If the network device does not configure a dedicated resource for the first cell to transmit beam failure recovery information, for example, the first cell is a secondary cell (Scell), the terminal can report the beam failure recovery information of the secondary cell in an implicit manner. For example, physical random access channel (PRACH) resources/physical uplink control channel (PUCCH) resources of the first cell and the second cell are mapped, and each first cell corresponds to one resource. Generally, the maximum number of first cells corresponding to the terminal is 32, so that the network device needs to reserve a maximum of 32 resources for the first cell to perform beam failure recovery information feedback. However, the actual number of first cells supported or activated by the terminal is less than 32, but the network equipment still needs to reserve a maximum of 32 resources, which causes a waste of resources.

Summary of the invention

The present application provides a method and device for beam failure reporting, which can report the beam failure of the Scell, thereby recovering the beam of the Scell, and can improve resource utilization.

In a first aspect, a method for reporting beam failure is provided. The method includes: receiving activation signaling, where the activation signaling is used to activate a first cell; and determining the beam used to transmit the first cell according to the activation signaling.

The terminal receives the activation signaling, and determines the first resource corresponding to the first cell according to the activation signaling, so that the terminal can transmit the beam failure recovery information of the first cell on the first resource. The network device can activate the resource corresponding to the first cell (ie, the first resource) for the terminal, and only needs to reserve the resource corresponding to the first cell. Compared with the traditional solution, the network device reserves a fixed size of resources (ie, all cells). Corresponding resources) are used to transmit the beam failure recovery information of the cell. The embodiment of the present application saves resource waste and improves resource utilization.

In this way, the network equipment only needs to reserve the resources corresponding to the first cell.

Detailed ways

The technical solution in this application will be described below in conjunction with the drawings.

The following describes the terms involved in this application in detail:

Beam:

The beam is a communication resource. The beam can be a wide beam, or a narrow beam, or other types of beams. The beam forming technology may be beamforming technology or other technical means. The beamforming technology may specifically be a digital beamforming technology, an analog beamforming technology, and a hybrid digital/analog beamforming technology. Different beams can be considered as different resources. The same information or different information can be sent through different beams. Optionally, multiple beams with the same or similar communication characteristics may be regarded as one beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. For example, a transmit beam can refer to the distribution of signal strength formed in different directions in space after a signal is transmitted by an antenna. The receiving beam may refer to the signal strength distribution of the wireless signal received from the antenna in different directions in space. It is understandable that one or more antenna ports forming a beam can also be regarded as an antenna port set. The embodiment of the beam in the agreement can still be a spatial filter.

Beamforming technology (beamforming):

Beamforming technology can achieve higher antenna array gain by oriented in a specific direction in space. Analog beamforming can be achieved through radio frequency. For example, a radio frequency link (RF chain) adjusts the phase through a phase shifter to control the change of the analog beam direction. Therefore, an RF chain can only shoot one analog beam at the same time.

Beam management resources:

Refers to resources used for beam management, which can also be embodied as resources used for calculation and measurement of beam quality. The beam quality includes layer 1 reference signal received power (layer 1 reference signal received power, L1-RSRP), layer 1 received reference signal quality (layer 1 reference signal received quality, L1-RSRQ), etc. Specifically, beam management resources may include synchronization signals, broadcast channels, downlink channel measurement reference signals, tracking signals, downlink control channel demodulation reference signals, downlink shared channel demodulation reference signals, uplink sounding reference signals, uplink random access signals, etc. .

Beam indication information:

Used to indicate the beam used for transmission, including the transmitting beam and/or the receiving beam. Including beam number, beam management resource number, uplink signal resource number, downlink signal resource number, absolute index of beam, relative index of beam, logical index of beam, index of antenna port corresponding to beam, index of antenna port group corresponding to beam, The index of the downlink signal corresponding to the beam, the time index of the downlink synchronization signal block corresponding to the beam, the beam pair link (BPL) information, the transmission parameter (Tx parameter) corresponding to the beam, and the reception parameter (Rx parameter) corresponding to the beam , The transmission weight corresponding to the beam, the weight matrix corresponding to the beam, the weight vector corresponding to the beam, the receiving weight corresponding to the beam, the index of the transmission weight corresponding to the beam, the index of the weight matrix corresponding to the beam, the index of the weight vector corresponding to the beam, the beam At least one of the index of the corresponding reception weight, the reception codebook corresponding to the beam, the transmission codebook corresponding to the beam, the index of the reception codebook corresponding to the beam, and the index of the transmission codebook corresponding to the beam. The downlink signal includes a synchronization signal, Broadcast channel, broadcast signal demodulation signal, channel state information downlink signal (channel state information reference signal, CSI-RS), cell specific reference signal (CS-RS), terminal specific reference signal (user equipment specific reference) signal, US-RS), downlink control channel demodulation reference signal, downlink data channel demodulation reference signal, and downlink phase noise tracking signal. The uplink signal includes any of the uplink random access sequence, uplink sounding reference signal, uplink control channel demodulation reference signal, uplink data channel demodulation reference signal, and uplink phase noise tracking signal. Optionally, the network device may also allocate QCL identifiers to beams having a QCL relationship among beams associated with the frequency resource group. The beam may also be called a spatial transmission filter, the transmit beam may also be called a spatial transmit filter, and the receive beam may also be called a spatial receive filter. The beam indication information can also be embodied as a transmission configuration index (TCI). The TCI can include various parameters, such as cell number, bandwidth part number, reference signal identifier, synchronization signal block identifier, quasi-co-location (quasi-co -location, QCL) type, etc. Among them, the parity relationship of quasi-co-location (QCL) is used to indicate that multiple resources have one or more identical or similar communication characteristics. For multiple resources with parity relationship, the same or Similar communication configuration. For example, if two antenna ports have a co-location relationship, then the large-scale characteristics of the channel transmitting one symbol on one port can be inferred from the large-scale characteristics of the channel transmitting one symbol on the other port. Large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receiving parameters, terminal device receiving beam number, transmitting/receiving channel correlation, receiving angle of arrival, receiver antenna Spatial correlation, main angle of arrival (angel-of-arrival, AoA), average angle of arrival, expansion of AoA, etc. Spatial QCL can be considered as a type of QCL. There are two angles to understand spatial: from the sending end or from the receiving end. From the perspective of the transmitting end, if the two antenna ports are quasi-co-located in the spatial domain, it means that the corresponding beam directions of the two antenna ports are spatially consistent, that is, the spatial filters are the same. From the perspective of the receiving end, if the two antenna ports are spatially quasi-co-located, it means that the receiving end can receive the signals sent by the two antenna ports in the same beam direction, that is, the reception parameter QCL.

Carrier component and carrier component (CC):

Carrier aggregation (CA) refers to the joint use of multiple CCs by the terminal, including continuous in-band, discontinuous in-band, and discontinuous in-band. CA can increase the available bandwidth and obtain a better transmission rate. The CA allows PDCCH and PDSCH to be in the same or different CCs, that is, cross-carrier scheduling is allowed. Among them, CC, bandwidth part (bandwidth part, BWP), CC/BWP, CC and/or BWP are usually equivalently replaced because they all describe a section of frequency domain resources. CC can also be equivalently replaced with a cell. Wherein, BWP represents a continuous frequency domain resource. For example, BWP can be understood as a continuous frequency band, the frequency band includes at least one continuous subband, and each bandwidth part can correspond to a set of system parameters (numerology). Different bandwidth parts can correspond to different system parameters.

Fig. 2 shows a schematic flowchart of a method for beam failure recovery in a traditional solution.

201: The terminal determines that the beam of the Pcell fails.

Specifically, the physical layer of the terminal periodically detects the beam failure detection reference signal (BFD RS), and determines whether the beam fails according to the beam quality of the BFD RS. For example, if the beam quality of the BFD RS satisfies the beam failure instance (beam failure instance) condition, that is, the beam quality is lower than the beam quality threshold, the beam failure instance indication is sent to the upper layer of the terminal. If the beam quality of the BFD RS that appears for N consecutive times meets the beam failure instance condition, the terminal's upper layer announces that the terminal's beam has failed.

202. The terminal searches for a new available beam.

Specifically, the upper layer of the terminal requests the physical layer of the terminal to send candidate beams that meet the condition of beam failure instance to the upper layer (that is, the beam quality is higher than a given beam quality threshold). The set of candidate beams (candidate beam RS) may be configured by the network device to the terminal.

203. The terminal sends a beam failure recovery request (BFRQ) to the network device.

Specifically, the upper layer of the terminal selects one from the set of candidate beams as the new available beam (for example, marked as q-new), and associates the new available beam with the random access channel (RACH). ) The resource is notified to the physical layer of the terminal. The physical layer of the terminal uses q-new on the RACH resource to send the BFRQ to the network device. The RACH resource is a resource allocated to the Pcell by the network device for BFRQ transmission.

204. The terminal receives the BFRQ response information from the network device.

Specifically, starting from the fourth time slot (slot) after sending the BFRQ, the terminal uses q-new to monitor a dedicated control channel resource set (control resource set, CORESET) and its corresponding search space (search space) to obtain The response information of the network device to the BFRQ. The response information is a physical downlink control channel (physical downlink control channel, PDCCH).

In the traditional solution, the network device configures a dedicated resource for the second cell to transmit beam failure recovery information. For example, the second cell is the primary cell (Pcell). After the beam in the Pcell fails, the corresponding resource can be used to send to the network device Beam failure recovery information, so that the failed beam can be recovered. If the network device does not configure a dedicated resource for the first cell to transmit beam failure recovery information, for example, the first cell is a secondary cell (Scell), the terminal can report the beam failure recovery information of the secondary cell in an implicit manner. For example, the PRACH resources/PUCCH resources of the first cell and the second cell are mapped, and each first cell corresponds to one resource. Generally, the maximum number of first cells corresponding to the terminal is 32, so that the network device needs to reserve a maximum of 32 resources for the first cell to perform beam failure recovery information feedback. However, the actual number of first cells supported or activated by the terminal is less than 32, but the network equipment still needs to reserve a maximum of 32 resources, which causes a waste of resources.

FIG. 3 shows a schematic flowchart of a method for reporting beam failure according to an embodiment of the present application.

301. The terminal receives activation signaling, where the activation signaling is used to activate the first cell. Correspondingly, the network device sends the activation signaling.

Specifically, the activation signaling may be a base station within the coverage of the first cell, or a base station within the coverage of another cell (for example, a base station within the coverage of the second cell), which is not limited in this application .

It should be noted that the embodiment of this application takes the terminal receiving one activation signaling as an example for description, but in the embodiment of this application, the terminal can also receive multiple activation signalings, and different activation signalings can be used to activate different cells. .

It should be noted that, unless otherwise specified, the same terms in the embodiments of the present application have the same meaning.

It should be understood that the embodiment of the present application takes the terminal receiving one activation signaling as an example for description, but in the embodiment of the present application, the terminal may also receive multiple activation signalings, and different activation signalings may be used to activate different cells.

It should also be understood that one activation signaling can be used to activate one cell or multiple cells, which is not limited in this application.

Optionally, the activation signaling format may be as shown in FIG. 4. In other words, activation signaling can occupy one byte (octet, oct), that is, 8 bits. C _i is the SCell index, if C _i = 1, then the i-th Scell is activated; if C _i =0, then the i-th SCell is deactivated. R is a reserved field.

Optionally, the activation signaling may also be as shown in FIG. 5. In other words, the activation signaling can occupy 4 bytes, that is, 16 bits. Among them, C _i is the SCell index, if C _i = 1, then the i-th Scell is activated; if C _i =0, then the i-th SCell is deactivated. R is a reserved field.

It should be noted that the value of the number of terminals can be C _i 1 is determined by the number of currently active SCell to statistics.

302. The network device activates the first resource corresponding to the first cell for the terminal.

Specifically, the network device may activate one resource corresponding to each cell for the terminal. The activation resource can be understood as a dedicated resource for transmitting certain types of information of the first cell. That is, the network device cannot use the resource to transmit other information, for example, it does not schedule other uplink information on the resource. Correspondingly, an inactive resource can be understood as the resource is available, that is, the network device can use the resource to schedule other uplink information.

303. The terminal determines, according to the activation signaling, a first resource used to transmit beam failure recovery information of the first cell, where the first resource is a physical random access channel (PRACH) resource of the second cell Or physical uplink control channel (PUCCH) resources.

Specifically, the resource used to transmit the beam failure recovery information of the first cell is to reuse the resource of the second cell, and the type of the resource may be the physical random access channel PRACH resource or the physical uplink control channel PUCCH resource of the second cell . In other words, the resource used to transmit the beam failure recovery information of the first cell may be the PRACH resource of the second cell, may also be the PUCCH resource of the second cell, or may also be the PRACH resource and the PUCCH resource. Or the first resource is a part of the PRACH resource or PUCCH resource of the second cell.

It should be noted that the embodiment of the present application does not limit the sequence of step 302 and step 303.

Optionally, the resource in the first resource in step 303 may also be a physical uplink shared channel (PUSCH) of the second cell.

304. The terminal sends the beam failure recovery information on the first resource.

Specifically, the terminal assumes that the first resource is available, that is, the first resource can be used to transmit beam failure recovery information of the first cell. In the embodiment of the present application, the terminal receives the activation signaling, and determines the first resource corresponding to the first cell according to the activation signaling, so that the terminal can transmit the beam failure recovery information of the first cell on the first resource. The network device can activate the resource corresponding to the first cell (ie, the first resource) for the terminal, and only needs to reserve the resource corresponding to the first cell. Compared with the traditional solution, the network device reserves a fixed size of resources (ie, all cells). Corresponding resources) are used to transmit the beam failure recovery information of the cell. The embodiment of the present application saves resource waste and improves resource utilization.

It should be noted that, after detecting the beam failure of the first cell, the terminal may send the beam failure recovery information of the first cell on the first resource. Wherein, the terminal fails to detect the beam of the first cell, either after detecting the beam failure of the first cell once, or detecting multiple beam failures of the first cell, and then determining the beam failure of the first cell. The terminal and the network device may preset a threshold for the number of beam failures. If the number of beam failures from the terminal to a certain cell exceeds the threshold, the terminal considers the beam of the cell to fail.

It should be understood that the network device reserves the first resource corresponding to the first cell, and after the terminal determines the first resource according to the first cell, the terminal and the network device agree on the purpose of using the first resource.

It should be noted that when the terminal receives multiple activation signalings, each activation signaling is used to determine the resource of the beam failure recovery information of the corresponding cell, so that the terminal can send the corresponding cell's information on different resources. Beam failure recovery information.

It should be understood that the beam failure recovery information in the embodiments of the present application may be any information related to beam failure recovery. For example, the beam failure recovery information may only indicate that a beam failure has occurred, and may also indicate a beam failure cell, and also It may indicate new beam information, etc., which is not limited in this application. Specifically, the beam failure recovery information may be "beam failure recovery request (BFRQ)" information.

It should also be understood that the first cell and the second cell may be controlled by the same network device, or may be controlled by different network devices, which is not limited in this application.

Optionally, the activation signaling may be media access control (MAC)-control element (CE), radio resource control (RRC) signaling, downlink control signaling (downlink control) information, DCI), system messages or broadcast messages and other signaling.

Optionally, the first cell is a secondary cell, and the second cell is a primary cell. In other words, the activation signaling can activate the secondary cell and indicate that the beam failure recovery information of the secondary cell can be transmitted using the resources of the primary cell, thereby saving resource waste.

Optionally, the first cell is a secondary cell, and the second cell may also be a secondary cell. Or the first cell is the primary cell and the second cell is the secondary cell. Or the first cell is the primary cell, the second cell is also the primary cell, and so on. This application does not limit this.

In an embodiment, the activation signaling may also explicitly indicate the first resource.

Specifically, when the network device activates the first cell, it also indicates the resource of the first cell for transmitting the beam failure recovery information, that is, the network device can flexibly indicate the resource of the second cell for transmitting the beam failure recovery of the first cell information.

It should be noted that when multiple cells are activated by one activation signaling, the resource indicated by the activation signaling may be one, that is, the multiple cells all feed back beam failure recovery information on the resource; or the activation signaling The indicated resources can also be multiple, and the terminal feeds back the beam failure recovery information of one cell on one resource.

Optionally, the activation signaling includes at least one field, and the at least one field may be used to indicate the first resource.

Specifically, the at least one field may be an original reserved field in the activation signaling, or may be a newly added field to indicate the first resource, which is not limited in this application.

For example, the at least one field may be a PRACH configuration index (PRACH configuration index) field or a PUCCH resource index (PUCCH resource index) field.

In another embodiment, the activation signaling may implicitly indicate the first resource.

Specifically, a specific mapping relationship between at least one cell and at least one resource. The resource type of the at least one resource may be PRACH resource, PUSCH resource or PUCCH resource of the second cell. In other words, the at least one resource is part or all of the PRACH resources, PUSCH resources, or PUCCH resources of the second cell. That is, each cell has a corresponding PRACH resource or PUCCH resource of the second cell. In this way, the terminal can determine the first resource corresponding to the first cell according to the first cell used for activation by the activation signaling and the mapping relationship.

It should be noted that the mapping relationship between at least one cell and at least one resource may specifically be that one cell corresponds to multiple resources, or multiple cells correspond to one resource, which is not limited in the embodiment of the present application.

It should be understood that the first cell is any one of the at least one cell.

Optionally, the mapping relationship may be pre-configured by the network device to the terminal through RRC signaling. Or the mapping relationship may be pre-appointed by the network device and the terminal, which is not limited in this application.

Optionally, the beam failure recovery information may include an identifier of the first cell, and the network device may determine that the beam of the first cell fails according to the first cell identifier.

Optionally, after the terminal completes the transmission of the beam failure recovery information, the network device may also send deactivation signaling, so that the dedicated resource is restored to the available resource of other information.

Optionally, after detecting that the beam of the first cell fails, the terminal may detect the newly available beam of the first cell, and send first indication information on the first resource, where the first indication information is used to indicate whether the terminal is Detect the newly available beam of the first cell. Correspondingly, the network device receives the first indication information on the first resource.

Specifically, the terminal may send first indication information on the first resource, and the network device can learn whether the terminal detects a newly available beam of the first cell according to the first indication information. If the network device learns from the first indication information that the terminal has not detected a new available beam of the first cell, the network device can trigger other reference signals (RS) to find a new beam as soon as possible. That is, the first indication information indicates whether a newly available beam of the first cell is detected, which helps the network device to perform a more reasonable subsequent process.

It should be noted that the sequence of the first indication information and the beam failure recovery information is not limited in the embodiment of the present application.

Optionally, in the case of detecting the newly available beam of the first cell, the terminal may also send second indication information, where the second indication information is used to indicate the beam identifier of the newly available beam of the first secondary cell. Correspondingly, the network device receives the second indication information.

Specifically, the network device can learn whether the second indication information exists according to the first indication information. If the first indication information indicates that the terminal detects a newly available beam of the first cell, the network device may wait to receive the second indication information. If the first indication information indicates that the terminal has not detected the newly available beam of the first cell, the network device does not need to wait for subsequent information, such as the second indication information.

It should be noted that the resource for sending the second indication information by the terminal may have a binding relationship with the resource for sending the first indication information. Optionally, the resource for the terminal to send the second indication information may be PRACH, PUCCH or PUSCH resource. Optionally, the resource for the terminal to send the second indication information may also be activated by the network device through activation signaling.

Optionally, the resource for the terminal to send the second indication information may be scheduled by the network device. The network device can learn whether the second indication information exists according to the first indication information. If the first indication information indicates that the terminal detects a newly available beam of the first cell, the network device may schedule the terminal to send the second indication information. If the first indication information indicates that the terminal does not detect the newly available beam of the first cell, the network device does not need to schedule the terminal to send the second indication information. Further, the network device can trigger a new round of beam training, or the network device can schedule other cells that have not failed beams for data transmission.

Optionally, the resource for sending the first indication information by the terminal and the resource for sending the second indication information by the terminal may be associated. For example, the offset value in time, the offset value of frequency resources, and the offset value of transmission power. For example, the terminal sending the first indication information and the terminal sending the second indication information should use the same transmission beam.

In the traditional solution, the network device configures a dedicated resource for the first cell to transmit beam failure recovery information. For example, the first cell is the primary cell (Pcell). After the beam in the Pcell fails, the corresponding resource can be used to send to the network device Beam failure recovery information, so that the failed beam can be recovered. If the network device does not configure dedicated resources for the second cell to transmit beam failure recovery information, for example, the second cell is a secondary cell (Scell), the terminal can report the beam failure recovery information of the secondary cell in an explicit manner. For example, the terminal may report the beam failure recovery information of the secondary cell with resources of a fixed size. The fixed-size resource can feed back the beam failure recovery information of the maximum number (N_max) of the secondary cells in the usual case. For example, under normal circumstances, the maximum number of secondary cells corresponding to the terminal is 32, and the fixed-size resource may be 5 bits. However, the actual number of secondary cells supported or activated by the terminal is less than 32, but the terminal still occupies 5 bits of resources to report the beam failure recovery information, which causes a waste of resources.

FIG. 6 shows a schematic flowchart of a method for reporting beam failure according to an embodiment of the present application.

601: The terminal determines the number of activated carrier component CCs of the terminal.

Specifically, the number of activated CCs of the terminal is the total number of CCs activated by the terminal. The terminal and network equipment can learn which CCs are in the active state and which CCs are in the inactive state. For example, the network device can control the CC of the terminal to be in the active state or the inactive state by sending activation signaling or deactivation signaling.

It should be noted that in the embodiments of the present application, CCs and cells have a corresponding relationship, that is, one activated CC can correspond to one activated cell, and accordingly, one activated CC identifier corresponds to one activated cell identifier.

It should be understood that in the embodiment of the present application, the terminal and the network device determine which CCs are in the active state can also be determined by the value of C _i as shown in FIG. 4 or FIG. 5, that is, when the value of C _i is 1, , The corresponding CC is active.

602. The terminal determines the resource required for transmitting the identifier of the activated CC according to the number of activated CCs.

Specifically, the terminal can determine the resources required to transmit the identification of the activated CC according to the number of activated CCs. For example, if the number of activated CCs is large, more resources can be used to transmit the identification of activated CCs; the number of activated CCs is small. Less resources can be used to transmit the identification of the activated CC. That is to say, the terminal can flexibly determine the resources required to transmit the identities of the activated CCs according to the number of activated CCs. Compared with the traditional solution transmitting the identities of the activated CCs according to fixed-size resources, the embodiments of the present application help to save resource overhead.

In other words, the index of the failed CC can only be selected from the activated CCs, that is, the maximum number of cells corresponding to the terminal N max is equal to the total number of CCs activated by the terminal (The failed CC index(es) should be only selected from activated SCells, ie ,N_max equals the total number of activated SCells, for SCell BFR).

Optionally, the resource required for transmitting the identification of the activated CC may be the required number of bits.

其中，N表示所述激活CC的数目，L表示传输激活CC的标识占用的比特数。例如，激活CC的数目为4个，则传输激活CC的标识所需的比特数可以是2个。这样本申请实施例能够准确的计算出传输激活CC的标识所需的比特数，更精确的节省资源浪费，更进一步提高资源利用率。 Optionally, the number of activated CCs and the number of bits required for transmitting the identifier of the activated CC may satisfy:

Wherein, N represents the number of the activated CCs, and L represents the number of bits occupied by transmitting the identification of the activated CCs. For example, if the number of activated CCs is 4, the number of bits required for transmitting the identification of the activated CCs may be 2. In this way, the embodiment of the present application can accurately calculate the number of bits required to transmit the identification of the activated CC, more accurately save resource waste, and further improve resource utilization.

It should be noted that the number of bits required to transmit the identification of the activated CC may be greater than or equal to L, which is not limited in this application.

个比特数。 Optionally, if q identities of the activated CC are transmitted, it is required

Number of bits.

Optionally, N may also be the number of active CCs in a CC group. The CC group may refer to the master cell group (MCG) or the secondary cell group (SCG) where the SCell is located. The CC group can also refer to all CCs managed by one MAC entity. The CC group may also be predefined by the protocol or formed by one or more CCs configured by the network device.

Optionally, assuming that the beams in a CC group are the same, N may also be the number of CC groups.

Optionally, N can also be the number of activated CCs minus the number of PCells, that is, the number of activated CCs-X, where X is the number of PCells. Optionally, the value of X can be 1.

It should be noted that the number of bits required to activate the CC identification can be greater than or equal to L, which is not limited in this application.

Optionally, the identification of the activated CC may be the index of the activated CC, or other identification, which is not limited in this application.

603. The terminal sends first indication information according to the resources required for the identification of the activated CC, where the first indication information includes the identification of the activated CC corresponding to the cell where the beam failed. Correspondingly, the network device receives the first indication information.

Specifically, the first indication information includes the identifier of the activated CC corresponding to the cell where the beam failed, and the terminal can determine the size of the resource occupied by the identifier of the activated CC in the first indication information according to the resources required to activate the CC determined in step 602, Compared with the traditional solution that the terminal occupies a fixed size of resources to transmit the active CC identifier, the embodiment of the present application can flexibly determine the resource occupied by the reasonable transmitting the active CC identifier, thereby saving resource overhead.

It should be understood that the cell may be a secondary cell, a primary cell, or other cells, etc., which is not limited in this application.

Optionally, before step 603, the terminal may also detect the newly available beam of the cell to obtain the detection result. The terminal sends second indication information to the network device, where the second indication information is used to indicate a cell with a beam failure, and to indicate whether a newly available beam of the cell with a beam failure is detected. Correspondingly, the network device receives the second indication information.

Specifically, the detection result is that the newly available beam of the cell is detected or the newly available beam of the cell is not detected. The second indication information may indicate that there are currently beam failure cells, but may not specifically indicate which cell has beam failure. In the case that the second indication information does not report a new beam, the network device cannot perform beam recovery either. Therefore, the index of the CC of the second indicator information feedback beam is not helpful (ie, although gNB can get failed CC index early, it still can't recovery the link without new beam. That's to say, there is no help to feedback failed CC index). Upon receiving the second indication information, the network device may predict the size of the resource occupied by the first indication information to be received according to the second indication information. For example, if the second indication information indicates that a new available beam of the cell is detected, the first indication information occupies a larger resource; if the second indication information indicates that no new available beam of the cell is detected, the first indication The resource occupied by the information is relatively small (for example, the number of bits occupied by the first indication information is L). In other words, the network device can know the size of the first indication information to be received in advance, thereby reducing the complexity of blindly detecting the first indication information.

It should be noted that the second indication information indicates that the newly available beam of the cell where the beam failed is not detected, which helps the network device to trigger other reference signals to find the new beam as soon as possible (for example, It may be helpful if whether no new beam identified information is reported in the first step.Thus, if no new beam identified, gNB can trigger another RS set to find new beamearlier.

Optionally, the second indication information may also indicate the number of cells with beam failure.

Specifically, the network device can learn the number of activated cells indicated by the first indication information to be received according to the number of cells in which the beam fails. In other words, the network device can more accurately learn the size of the resource occupied by the first indication information.

For example, if the second indication information indicates that the number of cells with beam failure is q, and indicates that no new available beams of the corresponding cell are detected, the number of bits occupied by the first indication information is q·L.

In an embodiment, when the terminal detects a newly available beam, the first indication information includes the identifier of the activated CC corresponding to the cell and the beam identifier of the newly available beam of the cell.

Specifically, when the terminal detects the newly available beam, the beam identifier of the newly available beam is carried in the first indication information, so that the network device can perform beam recovery according to the identifier of the newly available beam, which improves beam recovery. s efficiency.

It should be understood that the first indication information may be carried in an aperiodic channel state information (channel state information, CSI) report (aperiodic CSI report).

Optionally, the terminal may determine the number of bits occupied by the beam identifier of the newly available beam of the cell according to the number of candidate beams of the cell configured by the network device. That is, the terminal can determine the number of bits occupied by the beam identifier of the newly available beam of the cell according to the number of candidate beams of the cell configured by the network device. For example, if the number of candidate beams in the cell is large, the beam identification of the newly available beam occupies more bits; if the number of candidate beams in the cell is small, the beam identification of the newly available beam occupies more bits. less.
