Detailed Description

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

The continuous emergence of new generation of new internet applications has placed higher demands on wireless communication technologies, driving the continuous evolution of wireless communication technologies to meet the demands of the applications.

In order to better support the communication of the internet of vehicles, LTE V2X is formulated in LTE Release14, and communication between the internet of vehicles (such as vehicles, people and roadside nodes) is supported through a direct link; then, in Release15, the LTE V2X technology is further enhanced, and functions such as carrier aggregation are supported. After Release15 version of the 5G new air interface NR technology is formulated, 3GPP starts a work of supporting internet of vehicles communication by using an NR interface, and completes 5G sidelink in Release16, so as to support direct communication between internet of vehicles devices through the NR technology. Further enhancements to NR Sidelink including power saving and reliability are made in Release 17.

Support for beam management is not considered in LTE V2X and Release16 NR V2X, because the primary frequency band where V2X applications are considered at the time is at a lower spectral position. With the progress and development of technology, the use of higher millimeter wave frequency band for the Sidelink communication is possible. When using, for example, the millimeter wave band (e.g. fr2 band), an analog beamforming or an analog-digital hybrid beamforming approach is generally employed. When both the transmitting UE and the receiving UE use analog beamforming, in order to obtain better communication quality, the transmitting beam and the receiving beam need to be paired to form a beam pair with better communication quality. Thus, there is a need to support beam management on a Sidelink.

Beam management in conventional NR DL or UL communications is performed by reference signals such as a downlink PSFCH (Physical Sidelink Feedback Channel, physical direct feedback channel), CSI-RS, or an uplink SRS (Sounding Reference Signal, channel sounding reference signal). The UE determines a receiving beam used for receiving different reference signals or reference signals on different resource positions by receiving the reference signals sent by the measuring base station; the base station manages a reception beam (QCL type) of the UE by indicating which reference signal or which reference signal on a resource location should be used when the UE receives the PDSCH (Physical Downlink Shared Channel) by the physical downlink shared channel. How a particular UE determines the receive beam protocol by reference signal measurements is not specified.

Depending on the UE capability, NR supports the UE to receive PDSCH with two received beams corresponding to different RSs or RS resources (e.g., PDSCH transmitted from two different TRPs for FDM (Frequency Division Multiplexing, frequency division multiplexing)). Since both uplink and downlink of the UE are controlled by the base station scheduling, the base station scheduling can ensure that the UE does not need to simultaneously receive multiple PDSCH requiring different reception beams beyond its capability.

In NR SL, a resource allocation scheme based on autonomous scheduling of UEs is supported, and one UE may simultaneously receive PSCCH/pscsch (Physical Sidelink Control Channel, physical direct connection control channel/Physical Sidelink Control Channel, physical direct connection shared channel) sent by multiple UEs on different frequency domain sub-channels (subchannels) in the same slot. The PSCCH/PSSCH transmitted by different UEs may correspond to different receive beam directions. Without central node coordination, the UE cannot guarantee that the number of receive beams does not exceed its capabilities. Accordingly, the UE also needs to be able to receive the PSFCH of FDM/CDM (Code Division Multiplexing ) fed back from multiple UEs at the same time, since different PSFCHs may be fed back from different UEs, and may also correspond to different receive beam directions.

In addition, in NR SL, the UE needs to perform reception operations such as sensing, CBR (Quasi Co Location, quasi co-sited) measurement, etc., and in R16/17/18, since analog beamforming is not considered, these reception operations can be performed simultaneously with the UE receiving PSCCH/PSSCH/PSFCH/S-SSB, etc. When the UE uses analog beamforming, the receive beams used by these receive operations may also be different from the receive beams used to receive the PSCCH/PSCCH transmitted by the particular UE. Due to the current UE capabilities, there is also a conflict between these receive operations.

Therefore, in NR SL beam management, when a UE needs to receive signals from a plurality of UEs using different reception beams at the same time, or when a UE needs to perform different SL reception operations at the same time, a conflict between different reception beams needs to be resolved.

Therefore, the disclosure proposes a direct communication method and apparatus, which solve the problem of receive beam collision when the UE SL simultaneously performs multiple receiving operations or receives multiple SL signals corresponding to different beams.

The direct communication method and device provided by the application are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a flow diagram of a direct communication method according to an embodiment of the disclosure. The method may be performed by an end User Equipment (UE). In the present disclosure, user equipment UE includes, but is not limited to, smart terminal devices, cellular phones, wireless devices, handsets, mobile units, vehicles, in-vehicle devices, etc.

As shown in fig. 1, the method may include the following steps.

S101, under the preset condition, using preset receiving beams or selecting M receiving beams to perform direct connection SL receiving operation.

The preset condition indicates that the SL receiving operation corresponds to N different receiving beams, where N is greater than M, and M is the number of receiving beams used by the UE for performing the SL receiving operation at the same time, and M is greater than or equal to 1.

In other words, M may be the number of reception beams used simultaneously by the UE for SL reception, where "use simultaneously" does not limit the value of M, that is, M may be applied to the present method when M is greater than or equal to 1. The specific value of M depends on the number of receiving operations in the same group or in different groups, and this disclosure is not limited.

Further, the preset case refers to that the UE receives a plurality of SL signals using different reception beams, or the UE needs to perform a plurality of different SL reception operations at the same time.

In the embodiment of the present disclosure, according to different specific scenarios meeting the preset conditions, the UE may perform the direct-connection SL receiving operation using a preset receiving beam, for example, the UE receives a specific S-SSB or SL CSI-RS resource using a default beam configured by the base station, and may also select M receiving beams to perform the direct-connection SL receiving operation, for example, the UE performs the corresponding SL receiving operation without exceeding M receiving beams from N receiving beams.

Therefore, in the embodiment of the disclosure, under a preset condition, the UE uses a preset receiving beam or selects M receiving beams to perform a direct link SL receiving operation, where the preset condition indicates that the SL receiving operation corresponds to N different receiving beams, N is greater than M, M is the number of receiving beams used by the UE to perform the SL receiving operation at the same time, and M is greater than or equal to 1, which considers how the UE determines that the receiving beams perform the direct link SL receiving operation when the SL receiving operation corresponding to the different receiving beams needs to be performed, so as to support beam management on the SL.

Among them, reference Signals (RSs) include, but are not limited to SSB (Synchronization Signal and PBCH block ), CSI-RS or uplink SRS (Sounding Reference Signal, channel sounding Reference Signal), etc.

In other words, the N reception beams differ in that QCLs (Quasi Co Location, quasi co-located) of the N reception beams are associated to different sets of time-frequency resources, i.e. RS set(s), and SL transmissions that do not have the same spatial reception parameters with respect to each other.

In some embodiments, the preset conditions include at least one of: the UE needs to receive multiple SL channels or signals simultaneously, which may come from other UEs in different geographic locations, so that different SL channels or signals respectively correspond to different reception beams; the UE needs to receive a physical direct control channel PSCCH or a physical direct shared channel PSSCH of the frequency division multiplexing FDM from different UEs in the same time unit; the UE needs to receive the physical direct feedback channel PSFCH from different UEs of FDM/code division multiplexing CDM in the same time unit; the UE needs to perform a plurality of different types of SL reception operations within one time unit, and the plurality of different types of SL reception operations correspond to different reception beams, respectively.

In other words, the preset case is that the UE needs to use N reception beams for SL reception at the same time, including that the UE needs to receive N SL channels or signals at the same time, and different SL channels or signals respectively correspond to different reception beams.

Further, the preset conditions specifically include, but are not limited to: the UE needs to receive PSCCH/PSSCH (Physical Sidelink Control Channel, physical direct control channel/Physical Sidelink Control Channel, physical direct shared channel) from different UEs of FDM (Frequency Division Multiplexing ) or PSFCH (Physical Sidelink Feedback Channel, physical direct feedback channel) from different UEs of FDM/CDM (Code Division Multiplexing ) at the same slot; the UE needs to execute a plurality of SL receiving operations of different types in one slot, and the different receiving operations respectively correspond to different receiving beams; a combination of the two.

Further, SL reception of different operation types includes, but is not limited to: PSCCH/PSSCH reception, S-SSB reception, PSFCH reception, sensing, CBR (Constant bit rate) measurement, etc.

In the 5G application scenario, the network device may be a 5G radio access network (NG-RAN) node, for example, a gNB or a NG-eNB, where the gNB may be used for independent networking, and the NG-eNB may be used for downward compatibility with a 4G network, so as to adapt to application requirements of different core networks, where a specific use case depends on the application scenario and is not limited herein.

The time units described in the embodiments of the present disclosure may include slots (slots), subframes (subframes), frames (subframes), sub slots (subslots), OFDM symbols (symbols), etc., without limitation in the present disclosure.

In summary, in the embodiments of the present disclosure, under a preset condition, a UE uses a preset reception beam or selects M reception beams to perform a direct link SL reception operation, where the preset condition indicates that the SL reception operation corresponds to N different reception beams, N is greater than M, M is the number of reception beams used by the UE to perform the SL reception operation at the same time, and M is greater than or equal to 1, which considers how the UE determines the reception beam and which of the SL reception operations are performed when the SL reception operation corresponding to the different reception beams needs to be performed, so as to implement supporting beam management on the SL.

Based on the embodiment shown in fig. 1 or fig. 2, fig. 3 shows a schematic flow chart of a direct communication method according to an embodiment of the disclosure. The method may be performed by a UE. As shown in fig. 3, the method may include the steps of:

s301, under the preset condition, using a preset receiving beam to perform direct connection SL receiving operation.

Further, performing the SL reception operation using the preset reception beam includes: performing SL reception operation by using a predefined or preconfigured preset receiving beam; or receiving configuration information of a preset receiving beam sent by the network equipment, and performing SL receiving operation by using the preset receiving beam.

In other words, the UE receives using a specific default reception beam, e.g. using an omni-directional antenna by default, or the default beam is a beam receiving specific S-SSB or SL CSI-RS resources, which may be base station configured, predefined or pre-configured by the UE.

The configuration information is obtained by pre-configuring, for example, by reading pre-configuring data stored in a UE chip, the configuration information is pre-defined, for example, a protocol is agreed in advance, and the base station is configured, for example, the UE receives the configuration information of a preset receiving beam sent by the network device.

In some embodiments, further comprising: and determining the value of M according to protocol convention or configuration information carried in downlink control signaling sent by network equipment, or determining the value of M according to the number of simultaneously used receiving beams supported by UE capability.

The specific explanation of the above embodiment refers to the embodiment shown in fig. 1, and will not be repeated here.

In summary, according to the direct communication method provided by the present disclosure, under a preset condition, a UE performs direct connection SL receiving operation using a preset receiving beam, where the preset condition indicates that the SL receiving operation corresponds to N different receiving beams, N is greater than M, M is greater than or equal to 1 for the number of receiving beams used by the UE while performing the SL receiving operation, and considering that when the SL receiving operation corresponding to the different receiving beams needs to be performed, the UE performs the direct connection SL receiving operation using the preset receiving beam, so as to support beam management on the SL, and avoid a receiving beam collision when the SL simultaneously performs multiple receiving operations or receives multiple SL signals corresponding to the different beams.

It should be noted that, in the embodiments of fig. 3, fig. 4, and fig. 5 below are further limited to the embodiments of fig. 1 or fig. 2, in the preset case, the selection order of selecting M reception beams for SL reception operation may be determined according to the methods of the embodiments of fig. 3, fig. 4, and fig. 5.

Based on the embodiment shown in fig. 1 or fig. 2, fig. 4 shows a schematic flow chart of a direct communication method according to an embodiment of the disclosure. The method may be performed by a UE. As shown in fig. 4, the method may include the steps of:

s401, under the preset condition, determining the priority of SL receiving operation corresponding to different receiving beams.

Further, determining priorities of SL receive operations corresponding to different receive beams includes at least one of:

when the receiving beam correspondingly receives PSCCH/PSSCH transmission, determining the priority of the PSCCH/PSSCH transmission according to the indication of the priority field in the first-stage through link control information or according to the logic channel contained in the MAC PDU and the highest priority field in the MAC CE;

When the receiving beam corresponds to the PSFCH transmission, determining the priority of the PSFCH transmission according to the priority of the PSCCH/PSSCH corresponding to the PSFCH; when the receiving beam correspondingly receives the S-SSB transmission, determining the priority of receiving the S-SSB transmission according to the predefined, preconfigured or configuration information carried in the downlink control signaling sent by the network equipment;

when the same reception beam corresponds to a plurality of different SL reception operations, the priority of the SL reception operation to which the reception beam corresponds is determined according to the highest priority among the plurality of SL reception operations.

For example, for PSCCH/PSSCH transmission, the priority is determined according to the indication of the priority field in the 1st stage SCI, or the highest priority of the logical channel and MAC CE contained in the MAC PDU; for PSFCH transmission, determining the priority according to the priority of the PSCCH/PSSCH corresponding to the PSFCH transmission; for transmission of the S-SSB, determining a priority according to the (pre) configuration information; for the operations of sending, CBR measurement, etc., its priority may also be determined from the (pre) configuration information or predefined as the lowest priority.

S402, selecting M receiving beams from N receiving beams according to descending order of priority to perform SL receiving operation.

In other words, based on step 401, the priority of SL transmission is determined, and the selection order of selecting M SL transmissions is determined according to the priority determination of SL transmission, that is, the M reception beams with high priority are preferentially selected from the N reception beams to perform the SL reception operation. In some embodiments, a reception beam of the UE performing the SL reception operation can cover the M reception beams, for example, a gain of the reception beam in a specific direction (e.g., a peak direction) of any one of the M reception beams is not less than a specific value; or the XdB beamwidth angle of any one of the M receive beams is within the receive beam YdB beamwidth angle, etc.

In summary, according to the direct communication method provided by the present disclosure, when SL receiving operations corresponding to different receiving beams need to be performed, the UE determines priorities of the SL receiving operations corresponding to the different receiving beams, and selects the receiving beams in descending order of the priorities to perform the SL receiving operations, so as to support beam management on the SL, and avoid receiving beam collision when the SL simultaneously performs multiple receiving operations or receives SL signals corresponding to multiple different beams.

Fig. 5 shows a schematic flow diagram of a direct communication method according to an embodiment of the present disclosure, based on the embodiment shown in fig. 1 or fig. 2. The method may be performed by a UE. As shown in fig. 5, the method may include the steps of:

S501, in a preset case, according to the type of the SL receiving operation, selecting M receiving beams from the N receiving beams to perform the SL receiving operation.

In the embodiment of the present disclosure, the selection order of selecting M SL transmissions is determined according to the type of SL reception operation, i.e., the reception behavior of the UE, for example, for N SL transmissions that need to be simultaneously received, M beams are selected in order of preferentially selecting PSCCH/PSSCH/PSFCH received beams, selecting serving received beams, selecting CBR measurements again, and the like. The order of the reception beam selection for the types of different SL reception operations is not limited by this disclosure.

In summary, according to the direct communication method provided by the present disclosure, under a preset condition, a UE selects M reception beams from N reception beams to perform an SL reception operation according to a type of the SL reception operation, where the preset condition indicates that the SL reception operation corresponds to N different reception beams, N is greater than M, M is the number of reception beams used by the UE to perform the SL reception operation at the same time, and M is greater than or equal to 1, which considers that when the SL reception operation corresponding to different reception beams needs to be performed, the UE selects the reception beam to perform the direct communication SL reception operation according to the type of the SL reception operation, so as to implement beam management supported on the SL, and avoid a reception beam collision when the SL simultaneously performs multiple reception operations or receives multiple SL signals corresponding to different beams.

In the embodiment of the disclosure, the selection order of selecting M SL transmissions is determined according to possible reception beam combinations supported by the UE, and the specific value of M is determined according to the number of SL reception operations in the same group or different groups, which is not limited in this disclosure.

The following are two grouping methods for N reception beams shown in the embodiments of the present disclosure:

in a grouping method, N receiving beams are grouped, wherein receiving beams in different receiving beam combinations support SL receiving operation simultaneously; and selecting M receiving beams belonging to different receiving beam combinations for SL receiving operation.

In other words, the same set of receive beams cannot be used simultaneously, while different sets of receive beams can be used simultaneously, the UE selecting a beam to use within the different sets of receive beams.

Further, the N reception beams may be grouped according to the antenna panel to which the N reception beams belong, so as to determine a reception beam combination supported by the UE, where the reception beams belonging to the same antenna panel are included in the same reception beam combination.

In other words, the antenna panels to which different beams belong are grouped, and the reception beams belonging to the same antenna panel are grouped into one group.

Further, selecting M reception beams belonging to different reception beam combinations for SL reception operation includes: and selecting a receiving beam with the highest priority corresponding to the SL receiving operation from the receiving beam combinations to carry out the SL receiving operation.

In other words, the UE selects the highest priority beam usage within each of the different sets of receive beams, where the receive beams within the different sets of receive beams may be used simultaneously.

In another grouping method, grouping N receive beams, determining a combination of receive beams supported by the UE includes: grouping N receiving wave beams, wherein the receiving wave beams in the same receiving wave beam combination support SL receiving operation at the same time; and selecting M receiving beams belonging to the same receiving beam combination for SL receiving operation.

In other words, the reception beams of different groups cannot be used simultaneously, while the reception beams of the same group can be used simultaneously, and the UE selects a beam to use within the same reception beam group.

Further, the N receive beams may be grouped according to the antenna panel to which the N receive beams belong, so as to determine a receive beam combination supported by the UE, where the receive beams belonging to different antenna panels are included in the same receive beam combination.

In other words, the antenna panels to which different beams belong are grouped, the reception beams belonging to the different antenna panels are grouped into one group,

further, selecting M reception beams belonging to the same reception beam combination for SL reception operation includes: determining a beam combination containing a reception beam having the highest priority corresponding to the SL reception operation; and determining M receiving beams from the beam combination to perform SL receiving operation.

In other words, the UE selects the beam with the highest priority for use in the same set of reception beams, where the reception beams in the same set of reception beams may be used simultaneously.
