Description

[Technical Field]

[0001] This application claims priority to a Chinese patent application filed with the China Patent Office on August 6, 2020, bearing application number 202010783500.2 and entitled "Electronic device and method for wireless communication, and computer-readable storage medium," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of wireless communication, and in particular to a group-based beam reporting mechanism. More particularly, the present application relates to an electronic device and method for wireless communication, and a computer-readable storage medium. [Background technology]

[0003] To assign an appropriate channel to a user equipment (UE), a network side (NW) performs downlink beam scanning for the UE based on downlink reference signals, such as a channel state information reference signal (CSI-RS) or a synchronization signal block (SSB). The UE measures the downlink reference signal using a received beam to obtain a measurement result on the beam quality of the corresponding downlink emitted beam and reports the measurement result to the network side. The network side instructs the UE on the downlink emitted beam to be applied based on the reported measurement result. For example, in the mmWave frequency band, multiple beams can be used for simultaneous communication. The network side here can be various base stations (gNBs and eNBs) or transmit / receive points (TRPs).

[0004] For example, a UE may support group-based beam quality reporting, i.e., it may report a group of (e.g., two) downlink emission beams, and the UE may simultaneously receive the group of downlink emission beams using one or two receive beams. However, the network side may not necessarily be able to simultaneously transmit the group of downlink emission beams. This is because typically, one antenna panel (either the network side or the UE side) can only simultaneously transmit one emission beam or receive beam. For a group of downlink emission beams from the same antenna panel, the network side cannot simultaneously emit these downlink emission beams. In this case, only single-beam operation can be performed, as shown in the example of FIG. 1. Note that the network side is represented by TRP#0 and has four antenna panels #0 to #3. Assume that the UE reports downlink emission beams Tx beam#1 and Tx beam#2 that can be simultaneously received by the UE. These two downlink emission beams cannot actually be transmitted simultaneously because they are both emitted by antenna panel #3 of TRP#0. In other words, the UE performs group-based beam quality reporting but can still only perform single beam operation.

[0005] In addition, in a multi-TRP scenario, as shown in Figure 2, the reported downlink emission beam groups may be emitted by different antenna panels, but these antenna panels may belong to the same TRP, so simultaneous transmission of multiple TRPs is not possible. Note that TRP#0 and TRP#1 each preferably have four antenna panels, enabling simultaneous transmission of TRP#0 and TRP#1 to the UE. Assume that downlink emission beams Tx beam#0 and Tx beam#2 that can be simultaneously received by the UE are reported by the UE and are emitted by antenna panels #3 and #1 of TRP#0, respectively. Since these downlink emission beams are from the same TRP, simultaneous transmission of TRP#0 and TRP#1 is not possible.

[0006] To solve the above-mentioned problems, it is desirable to provide an improved group-based beam reporting mechanism. Summary of the Invention [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0017] The following describes exemplary embodiments of the present invention in conjunction with the drawings. For clarity and brevity, not all features of actual embodiments are described in the specification. It should be understood that embodiment-specific decisions must be made in the course of developing such actual embodiments to achieve the developer's specific goals, including, for example, system and business constraints that may vary from embodiment to embodiment. It should also be understood that, while the development effort may be highly complex and time-consuming, it would be a routine undertaking for those skilled in the art having the benefit of this disclosure.

[0018] It should also be noted that in order to avoid obscuring the present disclosure with unnecessary details, the drawings only show device configurations and / or processing steps that are closely related to the solutions of the present disclosure, and omit other details that are largely irrelevant to the present disclosure.

[0019] <First Example> Figure 3 is a block diagram showing functional modules of an electronic device 100 for wireless communication according to one embodiment of the present application. As shown in Figure 3, the electronic device 100 includes a transmitter 101 configured to transmit downlink reference signal resource configuration information to a UE for downlink beam scanning, the downlink reference signal resource configuration information including information of a TRP for emitting a downlink emission beam, and a receiver 102 configured to receive from the UE a group-based beam quality report for the network side to determine a group of downlink emission beams that can be simultaneously emitted to the UE and simultaneously received by the UE.

[0020] The transmitter 101 and the receiver 102 may be implemented by one or more processing circuits, which may be implemented as, for example, a chip or a processor. It should be understood that the functional units in the electronic device shown in Fig. 3 are merely logical modules partitioned based on the specific functions to be implemented, and do not limit the specific implementation form. The present invention may also be applied to other electronic devices described later.

[0021] The electronic device 100 may be installed in, for example, a base station or communicatively connected to a base station. The base station described herein may be a gNB, eNB, TRP, access point (AP), or the like. Here, the electronic device 100 may be implemented at the chip level or the device level. For example, the electronic device 100 may operate as a base station itself and may further include external devices such as a memory and a transceiver (not shown). The memory is used to store programs executed by the base station to realize various functions and related data information. The transceiver may include one or more communication interfaces to support communication between different devices (e.g., user equipment, other base stations, etc.), but the implementation form of the transceiver is not specifically limited here.

[0022] Here, the downlink reference signal can be a CSI-RS or SSB, and through beamforming, each downlink reference signal corresponds to one downlink emission beam direction. For example, the 3GPP (registered trademark) 5G standard proposes using a Transmission Configuration Indicator (TCI) state to indicate the downlink emission beam. Each TCI state corresponds to one downlink reference signal, i.e., one downlink emission beam direction.

[0023] The downlink reference signal resource configuration information is used to configure the time-frequency resources of the downlink reference signals measured by the UE. Since different downlink reference signals correspond to different downlink beam directions, this corresponds to the UE performing downlink beam scanning. The UE sequentially measures the quality of the downlink beams, selects a beam with good quality based on, for example, the L1-RSRP or L1-SINR criteria, and reports it to the network side. For example, the UE can report the identifier (ID) of the selected beam, such as a CSI-RS Resource Indicator (CRI) or an SSB Resource Indicator (SSBRI).

[0024] In this embodiment, the downlink reference signal resource configuration information includes information of the TRP that emits the downlink emission beam, that is, the UE can know which TRP the measured downlink emission beam comes from, so that the UE can avoid selecting and reporting beams from the same TRP.

[0025] According to the current 3GPP protocol, a UE can configure up to two TRPs, and multiple downlink control channel resources (CORESETs) can be configured for each TRP. A parameter CORESETPoolIndex is set in the CORESET to distinguish different TRPs. For example, the CORESETPoolIndex of the CORESET in which the physical downlink control channel (PDCCH) transmitted by TRP#0 exists is set to 0, and the CORESETPoolIndex of the CORESET in which the physical downlink control channel (PDCCH) transmitted by TRP#0 exists is set to 1. 1 The CORESETPoolIndex of the CORESET in which the PDCCH transmitted by the

[0026] Therefore, the CORESETPoolIndex of a TRP can be used as the information of the TRP, that is, the downlink reference signal resources of the same TRP can be associated with the same CORESETPoolIndex.

[0027] The downlink reference signal resource configuration information of this embodiment can be transmitted to the UE via Radio Resource Control (RRC) signaling. As an example, Figure 4 shows a schematic diagram of configuring CSI-RS resources via RRC signaling in pseudocode. Based on the existing code, the last line of "controlResourceSetId" is added, and the value is taken as the CORESETPoolIndex corresponding to the TRP, thereby indicating the information of the TRP corresponding to the CSI-RS resource.

[0028] 4 shows an example of the RRC configuration, and it should be understood that various other configuration methods are possible. It is sufficient to associate a set of downlink reference signal resources of one TRP with the TRP. For example, the set of downlink reference signal resources of one TRP may be included in one list to configure a CORESETPoolIndex for the TRP, and the set of downlink reference signal resources of another TRP may be included in another list to configure a CORESETPoolIndex for the other TRP.

[0029] In addition, different antenna panels of a TRP can be assigned to different resource sets of downlink reference signal resources, so that the UE can determine the antenna panel of the downlink emission beam corresponding to each downlink reference signal resource. Figure 5 shows an example in which different antenna panels correspond to different downlink reference signal resource sets. Note that the four antenna panels of TRP#0 are associated with reference signal resource sets RS Resource Set#0 to RS Resource Set#3, respectively, and these resource sets have the same TRP ID, i.e., CORESETPoolIndex of TRP#0. Similarly, the four antenna panels of TRP#1 are associated with reference signal resource sets RS Resource Set#4 to RS Resource Set#7, respectively, and these resource sets have the same TRP ID, i.e., CORESETPoolIndex of TRP#1.

[0030] The above configuration allows the UE to know which antenna panel of which TRP the measured downlink emission beam is from, thus avoiding the UE selecting and reporting beams from the same panel of the same TRP.

[0031] As described above, after the UE completes the measurement, it needs to report the measurement result to the network side, and the network side will instruct the UE which downlink emission beam to use according to the measurement result. In this embodiment, the UE performs group-based beam quality reporting, so that the network side can determine a group of downlink emission beams for the UE based on the beam quality report, and the group of downlink emission beams can be simultaneously emitted by the network side and simultaneously received by the UE.

[0032] In a first example, the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of a receiving beam set for the UE to receive the beam group. Note that the receiving beams in the receiving beam set may be simultaneously emitted by the UE. As described above, the UE can ensure that each beam in the beam group is simultaneously emitted by selecting each downlink emission beam in the beam group from a different TRP or from a different antenna panel of the same TRP according to the CORESETPoolIndex in the downlink reference signal resource configuration information.

[0033] For ease of understanding, FIG. 6 shows a schematic diagram of group-based beam quality reporting in this example. Note that the UE forms two receive beam sets, Rx beam Set#0 (receive beams represented by dotted lines) and Rx beam Set#1 (receive beams represented by solid lines), where Rx beam Set#0 can receive Tx beam#0 and Tx beam#1, and Rx beam Set#1 can receive Tx beam#2. It can be seen that receive beams in the same receive beam set are located on different antenna panels and can therefore be emitted simultaneously. For example, the UE can report one or more beam groups. Specifically, the UE can report Tx beam#0 and Tx beam#1, which belong to different TRPs, and the receive beam set Rx beam Set#0, which can receive these two beams. The UE may also report the beam quality of Tx beam#0 and Tx beam#1. In this way, if the beam quality of Tx beam#0 and Tx beam#1 meets the requirement, the network side can directly assign this group of downlink emission beams to the UE.

[0034] The specific reporting format of the UE is not limited and may include the various information described above. For example, the downlink transmission beam and the reception beam set may be reported in a corresponding format. For example, in FIG. 6, the UE may report the following: Tx beam#0<->Rx beam Set#0, Tx beam#1<->Rx beam Set#0, Tx beam#2<->Rx beam Set#1.

[0035] In addition, the transmitting unit 101 can be further configured to transmit a group beam indication to the UE, and the group beam indication includes an identifier of a receiving beam set corresponding to the group of downlink emission beams determined by the network side for the UE. In the example shown in Figure 6, for example, the group beam indication may be Rx beam Set #0.

[0036] It should be understood that the form of the group beam indication is not limited to this. For example, a TCI state ID may be further associated with a receiving beam set identifier, i.e., the TCI state ID and the receiving beam set identifier have a predetermined correspondence relationship. This predetermined correspondence relationship may be notified to the UE in advance via RRC signaling, or may be agreed upon in advance between the network side and the UE. In this case, the group beam indication may include the TCI state ID. This method can reduce the impact on existing protocols as much as possible and save overhead.

[0037] In a second example, the group-based beam quality report includes at least the identifier of the UE's antenna panel and the identifier of the downlink emission beam received by the antenna panel. That is, the UE reports according to the antenna panel. FIG. 7 shows a schematic diagram of the group-based beam quality report in this example. Note that the UE's antenna panel #0 receives downlink emission beams Tx beam #0 and Tx beam #1, and the UE's antenna panel #1 receives downlink emission beam Tx beam #2. The beam quality report may have a format such as Tx beam #0<->antenna panel #0, Tx beam #1<->antenna panel #0, Tx beam #2<->antenna panel #1, or other equivalent format.

[0038] As described above, the UE can know the information of the TRP or antenna panel corresponding to each downlink emission beam, and in order to realize simultaneous transmission of multiple beams, the UE will use different antenna panels to receive downlink emission beams from different TRPs or different antenna panels of the same TRP as much as possible.

[0039] 8, in this example, the electronic device 100 may further include a determination unit 103 configured to determine a group of downlink emission beams for the UE based on a group-based beam quality report from the UE, such that each downlink emission beam in the group of downlink emission beams is emitted by a different TRP or is emitted by a different antenna panel of the same TRP and received by a different antenna panel of the UE. For example, in the example shown in FIG. 7, Tx beam #1 and Tx beam #2 may be assigned to the UE.

[0040] For example, the identifier of an antenna panel may be represented by a sounding reference signal resource set identifier (SRS Reference Set ID), which corresponds to a beam used by one antenna panel when performing uplink beam scanning, and thus can represent the corresponding antenna panel.

[0041] The transmitting unit 101 is further configured to transmit a group beam instruction to the UE, the group beam instruction including an identifier of each downlink emission beam and an identifier of an antenna panel for the UE to receive the downlink emission beam. Taking FIG. 9 as an example, the group beam instruction may include, for example, Tx beam #1, antenna panel #0, Tx beam #2, and antenna panel #1.

[0042] If each antenna panel of the UE reports a different downlink emission beam, the group beam instruction does not need to include an identifier of the antenna panel. On the other hand, if two or more antenna panels report the same downlink emission beam, the group beam instruction can associate the downlink emission beam with two or more antenna panels, i.e., instruct the UE to receive using two or more antenna panels.

[0043] Different UEs may have different beam quality reporting capabilities, for example, some UEs support group-based beam quality reporting and some UEs do not support group-based beam quality reporting. Correspondingly, the receiving unit 102 may be further configured to obtain information about the UE's beam quality reporting capabilities from the UE, and the determining unit 103 may configure the UE's beam quality reporting scheme based on the information. For example, the transmitting unit 101 may notify the UE of the beam quality reporting scheme via RRC signaling.

[0044] For example, the UE's beam quality reporting capability includes one of not supporting group-based beam quality reporting, supporting group-based beam quality reporting scheme 1, supporting group-based beam quality reporting scheme 2, and supporting both group-based beam quality reporting scheme 1 and group-based beam quality reporting scheme 2, wherein in group-based beam quality reporting scheme 1 (i.e., the scheme described in the first example), the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of the receiving beam set for the UE to receive the beam group, and in group-based beam quality reporting scheme 2 (i.e., the scheme described in the second example), the group-based beam quality report includes at least an identifier of the UE's antenna panel and an identifier of the downlink emission beam received by the antenna panel.

[0045] For example, the determining unit 103 may determine a beam quality reporting scheme for the UE based on the beam quality reporting capability of the UE. For example, if the UE can support both Scheme 1 and Scheme 2, the determining unit 103 may determine one of the two schemes as the beam quality reporting scheme to be used by the UE.

[0046] Furthermore, if the UE can support group-based beam quality reporting, the receiver 102 may be further configured to acquire more detailed parameters related to the UE's beam quality reporting capability from the UE. For example, the receiver 102 may further acquire information from the UE regarding the maximum number of beam groups that the UE can report and the maximum number of beams in each group. Taking Scheme 1 as an example, the receiver 102 may acquire {Alt.1, N=4, K=2} from the UE, indicating that the UE supports beam quality reporting scheme 1 and can report up to four beam groups, each containing up to two different downlink launch beams.

[0047] In short, the electronic device 100 according to this embodiment can inform both the network side and the UE of the information of the TRP that emits the downlink emission beam by modifying the downlink reference signal resource configuration information, and improve the beam quality reporting based on the UE group, thereby enabling the network side to determine the group of downlink emission beams that can be simultaneously emitted to the UE and simultaneously received by the UE, i.e., ensuring that simultaneous transmission of multiple beams is possible.

[0048] <Second Example> Figure 9 is a block diagram showing functional modules of an electronic device 200 for wireless communication according to one embodiment of the present application. As shown in Figure 9, the electronic device 200 includes: a receiving unit 201 configured to receive downlink reference signal resource configuration information from the network side, including information of a TRP for emitting a downlink emission beam, for downlink beam scanning; and a transmitting unit 202 configured to transmit a group-based beam quality report to the network side, for the network side to determine a group of downlink emission beams that can be simultaneously emitted and simultaneously received by the UE.

[0049] The receiving unit 201 and the transmitting unit 202 can be realized by one or more processing circuits, and the processing circuits can be realized as, for example, a chip or a processor. It should be understood that each functional unit in the electronic device shown in Fig. 9 is merely a logical module partitioned based on the specific function to be realized, and does not limit the specific implementation form.

[0050] The electronic device 200 may be installed in a UE or communicatively connected to the UE. Here, the electronic device 200 may be implemented at a chip level or a device level. For example, the electronic device 200 may operate as a UE itself and may further include external devices such as a memory and a transceiver (not shown). The memory is used to store programs and related data information that the user equipment needs to execute to perform various functions. The transceiver may include one or more communication interfaces to support communication between different devices (e.g., a base station, another user equipment, etc.), but the implementation of the transceiver is not specifically limited here.

[0051] Hereinafter, the same or similar matters as those in the first embodiment will not be repeated, so please refer to the description of the first embodiment.

[0052] Similarly, the downlink reference signal can be CSI-RS or SSB, and through beamforming, each downlink reference signal corresponds to one downlink emission beam direction. The downlink reference signal resource configuration information is used to configure the time-frequency resources of the downlink reference signals measured by the UE. Since different downlink reference signals correspond to different downlink emission beam directions, this corresponds to downlink beam scanning for the UE. The UE sequentially measures the quality of the downlink emission beams, selects a beam with good quality based on, for example, the L1-RSRP or L1-SINR criteria, and reports it to the network side. For example, the UE can report the identifier (ID) of the selected beam, such as CRI or SSBRI.

[0053] In this embodiment, the downlink reference signal resource configuration information includes information about the TRP that emits the downlink emission beam. The receiver 201 can receive the downlink reference signal resource configuration information via RRC signaling. The TRP information can include, for example, the CORESETPoolIndex of the TRP. That is, downlink reference signal resources of the same TRP are associated with the same CORESETPoolIndex. Specific details have already been provided in the first embodiment, and are also applicable to this embodiment and will not be repeated here.

[0054] The UE can analyze the downlink reference signal resource configuration information to know which TRP the measured downlink emission beam is from, so that the UE can avoid selecting and reporting beams from the same TRP as much as possible.

[0055] Furthermore, different antenna panels of the TRP may correspond to different resource sets of the downlink reference signal resources, so that the UE can determine the antenna panel of the downlink emission beam corresponding to each downlink reference signal resource, and can avoid selecting and reporting beams from the same panel of the same TRP as much as possible. A detailed description of this correspondence has already been provided in the first embodiment with reference to Figure 5, so it will not be repeated here.

[0056] Correspondingly, as shown in FIG. 10, the electronic device 200 may further include a determination unit 203.

[0057] In a first example, the determination unit 203 is configured to determine the beam group to report so that each downlink emission beam in each beam group is emitted by a different TRP or is emitted by a different antenna panel of the same TRP and received by a different antenna panel of the UE.

[0058] For example, the group-based beam quality report transmitted by the transmitting unit 202 includes at least an identifier of each downlink emission beam in the beam group and an identifier of a receiving beam for the UE to receive the beam group set. Furthermore, the receiving beams in the receiving beam set can be simultaneously emitted by the UE. As described above, the determining unit 203 ensures that each beam in the beam group can be simultaneously emitted by the network side by selecting each downlink emission beam in the beam group from a different TRP or from a different antenna panel of the same TRP according to the CORESETPoolIndex in the downlink reference signal resource configuration information.

[0059] The receiving unit 201 is further configured to receive from the network side a group beam instruction including an identifier of a receiving beam set corresponding to a group of downlink emission beams determined by the network side for the UE. The form of the group beam instruction is not limited thereto. For example, a TCI state ID is associated with an identifier of the receiving beam set, i.e., the TCI state ID and the identifier of the receiving beam set have a predetermined correspondence relationship. The predetermined correspondence relationship may be obtained in advance from the network side via RRC signaling, or may be agreed upon in advance between the network side and the UE. In this case, the group beam instruction may include the TCI state ID. This method can minimize the impact on existing protocols and save overhead as much as possible.

[0060] In a second example, the group-based beam quality report includes at least an identifier of the UE's antenna panel and an identifier of the downlink emission beam received by the antenna panel. That is, the UE reports according to the antenna panel. As described above, the UE can know the information of the TRP or antenna panel corresponding to each downlink emission beam, and realize simultaneous transmission of multiple beams. In order to achieve this, the determining unit 203 determines the group-based beam quality report so that different antenna panels receive downlink emission beams from different TRPs or downlink emission beams from different antenna panels of the same TRP. quality The report is determined.

[0061] The receiving unit 201 is further configured to receive a group beam instruction from the network side, where the group beam instruction includes, for example, an identifier of each downlink emission beam in the group of downlink emission beams determined for the UE by the network side, and an identifier of an antenna panel through which the UE receives the downlink emission beam. If each antenna panel of the UE reports a different downlink emission beam, the group beam instruction does not need to include the identifier of the antenna panel. On the other hand, if two or more antenna panels report the same downlink emission beam, the group beam instruction can associate the downlink emission beam with two or more antenna panels, that is, the UE receives it using two or more antenna panels.

[0062] For example, the identifier of the antenna panel may be represented by an SRS Reference Set ID, which corresponds to the beam used by one antenna panel when performing uplink beam scanning, and thus can represent the corresponding antenna panel.

[0063] More specific explanations and schematic examples of the above two examples have already been provided in the first embodiment, so they will not be repeated here.

[0064] Different UEs may have different beam quality reporting capabilities, for example, some UEs support group-based beam quality reporting and some UEs do not support group-based beam quality reporting. Correspondingly, the transmitting unit 202 may be further configured to transmit information about the UE's beam quality reporting capabilities to the network side, and the receiving unit 201 may obtain the configured beam quality reporting scheme for the UE from the network side. For example, the receiving unit 201 may obtain the information about the beam quality reporting scheme through RRC signaling.

[0065] For example, the UE's beam quality reporting capability includes one of not supporting group-based beam quality reporting, supporting group-based beam quality reporting scheme 1, supporting group-based beam quality reporting scheme 2, and supporting both group-based beam quality reporting scheme 1 and group-based beam quality reporting scheme 2, wherein in group-based beam quality reporting scheme 1 (i.e., the scheme described in the first example), the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of the receiving beam set for the UE to receive the beam group, and in group-based beam quality reporting scheme 2 (i.e., the scheme described in the second example), the group-based beam quality report includes at least an identifier of the UE's antenna panel and an identifier of the downlink emission beam received by the antenna panel.

[0066] In addition, if the UE can support group-based beam quality reporting, the transmitting unit 202 can further transmit more detailed parameters regarding the UE's beam quality reporting capability to the network side. For example, the transmitting unit 202 can further transmit information regarding the maximum number of beam groups that the UE can report and the maximum number of beams in each group to the network side.

[0067] In short, the electronic device 200 according to this embodiment can inform both the network side and the UE of the information of the TRP that emits the downlink emission beam by modifying the downlink reference signal resource configuration information, and improve the beam quality reporting based on the UE group, thereby enabling the network side to determine the group of downlink emission beams that can be simultaneously emitted to the UE and simultaneously received by the UE, i.e., ensuring that simultaneous transmission of multiple beams is possible.

[0068] For ease of understanding, Figure 11 shows a schematic diagram of the information flow between the network side and the UE. Please note that this flowchart is schematic and not limiting.

[0069] The UE reports its beam quality reporting capability to the network side. In the example shown in FIG. 1, it is assumed that the UE supports group-based beam quality reporting, for example, both Scheme 1 and Scheme 2 described above. The network side determines that the UE should use Scheme 1 for beam quality reporting according to the capability information and instructs the UE to use Scheme 1. The network side also transmits downlink reference signal resource configuration information, including information on the emission TRP of each downlink emission beam, to the UE via RRC signaling. The network side performs downlink beam scanning based on the downlink reference signal resource configuration information. Correspondingly, the UE performs beam measurement and performs group-based beam quality reporting using Scheme 1, for example, reporting the identifiers of each downlink emission beam in the beam group and the identifiers of the receiving beam sets for the UE to receive the beam groups. The network side determines the beam to apply to the UE according to the reported beam quality measurement results and transmits a group beam instruction, for example, the identifiers of the receiving beam sets described above, or a corresponding TCI status ID, to the UE.

[0070] <Third Example> In the above embodiments, several processes or methods have been clearly disclosed in the course of describing the electronic device for wireless communication. The following provides an overview of these methods without repeating some of the details already discussed above. Although these methods have been disclosed in the course of describing the electronic device for wireless communication, they do not necessarily utilize or be performed by the components described. For example, the embodiments of the electronic device for wireless communication may be partially or completely realized by hardware and / or firmware, while the following methods for wireless communication may be completely realized by a computer-executable program. Of course, these methods may utilize the hardware and / or firmware of the electronic device for wireless communication.

[0071] 12 shows a flowchart of a method for wireless communication according to an embodiment of the present application, the method includes: sending downlink reference signal resource configuration information to a UE for downlink beam scanning, the downlink reference signal resource configuration information including information of a TRP for emitting a downlink emitted beam (S11); and receiving from the UE a group-based beam quality report (S12) for the network side to determine a group of downlink emitted beams that can be simultaneously emitted to the UE and simultaneously received by the UE. The method is, for example, performed by the network side.

[0072] For example, the information of a TRP includes a CORESETPoolIndex of the TRP, and different antenna panels of the TRP may correspond to different resource sets of downlink reference signal resources, so that the UE can determine the emission antenna panel of the downlink emission beam corresponding to each downlink reference signal resource.

[0073] As shown in the dotted box in the figure, the above method may further include step S13 of sending a group beam instruction to the UE.

[0074] In one example, the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of a receiving beam set for the UE to receive the beam group. The group beam instruction includes, for example, an identifier of a receiving beam set corresponding to the group of downlink emission beams determined for the UE by the network side. Alternatively, the group beam instruction may include an identifier of a TCI state, and the identifier of the TCI state and the identifier of the receiving beam set have a predetermined correspondence relationship.

[0075] In another example, the group-based beam quality report includes at least an identifier of an antenna panel of the UE and an identifier of a downlink emission beam received by the antenna panel, and the above method further includes determining a group of downlink emission beams based on the group-based beam quality report so that each downlink emission beam in the group of downlink emission beams is emitted by a different TRP or is emitted by a different antenna panel of the same TRP and received by a different antenna panel of the UE.

[0076] For example, an antenna panel identifier may be represented by an SRS resource set identifier.

[0077] The group beam instruction sent in step S13 may include an identifier of each downlink emission beam and an identifier of the antenna panel through which the UE receives the downlink emission beam.

[0078] In addition, the above method further includes obtaining information about the beam quality reporting capability of the UE from the UE, and configuring a beam quality reporting manner of the UE based on the information.

[0079] For example, the UE's beam quality reporting capability includes one of not supporting group-based beam quality reporting, supporting group-based beam quality reporting scheme 1, supporting group-based beam quality reporting scheme 2, and supporting both group-based beam quality reporting scheme 1 and group-based beam quality reporting scheme 2, wherein in group-based beam quality reporting scheme 1, the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of the receiving beam set for the UE to receive the beam group, and in group-based beam quality reporting scheme 2, the group-based beam quality report includes at least an identifier of the UE's antenna panel and an identifier of the downlink emission beam received by the antenna panel.

[0080] Furthermore, information regarding the maximum number of beam groups that the UE can report and the maximum number of beams in each group can also be obtained from the UE.

[0081] 13 shows a flowchart of a method for wireless communication according to an embodiment of the present application, the method including: receiving downlink reference signal resource configuration information from a network side for downlink beam scanning, the downlink reference signal resource configuration information including information of transmitting and receiving points that emit downlink emission beams (S21); and sending a group-based beam quality report to the network side, for the network side to determine groups of downlink emission beams that can be simultaneously emitted to and received by the UE (S22). The method is, for example, performed on the UE side.

[0082] For example, the information of the TRP includes a CORESETPoolIndex of the TRP. Different antenna panels of the TRP may correspond to different resource sets of downlink reference signal resources, and the method further includes determining a beam group to report so that each downlink emission beam in each beam group is emitted by a different antenna panel of the TRP and received by a different antenna panel of the UE.

[0083] The above method may further include determining a beam group to report such that each downlink emitted beam in each beam group is emitted by a different TRP and received by a different antenna panel of the user equipment.

[0084] As shown in the dotted box in Figure 13, the above method may further include S13 of receiving a group beam instruction from the network side.

[0085] In one example, the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of a receiving beam set for the UE to receive the beam group. The group beam instruction includes, for example, an identifier of a receiving beam set corresponding to the group of downlink emission beams determined for the UE by the network side. Alternatively, the group beam instruction includes an identifier of a TCI state, where the identifier of the TCI state and the identifier of the receiving beam set have a predetermined correspondence relationship.

[0086] In another example, the group-based beam quality report includes at least an identifier of an antenna panel of the UE and an identifier of a downlink emission beam received by the antenna panel. The method may be configured to generate a group-based beam quality report such that different antenna panels receive downlink emission beams from different TRPs or downlink emission beams from different antenna panels of the same TRP. quality It can further include determining a report.

[0087] For example, an antenna panel identifier may be represented by an SRS resource set identifier.

[0088] The above method may further include sending information about the beam quality reporting capability of the UE to the network side, and obtaining a beam quality reporting scheme configured for the UE from the network side.

[0089] The UE's beam quality reporting capability includes one of not supporting group-based beam quality reporting, supporting group-based beam quality reporting method 1, supporting group-based beam quality reporting method 2, and supporting both group-based beam quality reporting method 1 and group-based beam quality reporting method 2, wherein in group-based beam quality reporting method 1, the group-based beam quality report includes at least an identifier of each downlink emission beam in the beam group and an identifier of the receiving beam set for the UE to receive the beam group, and in group-based beam quality reporting method 2, the group-based beam quality report includes at least an identifier of the UE's antenna panel and an identifier of the downlink emission beam received by the antenna panel.

[0090] Furthermore, the UE can also transmit information to the network side regarding the maximum number of beam groups that it can report and the maximum number of beams in each group.

[0091] The above methods may be used in combination or individually. The details have already been explained in detail in the first and second embodiments, so they will not be repeated here.

[0092] The techniques of the present disclosure are applicable to a variety of products.

[0093] For example, the electronic device 100 may be implemented as various base stations. The base station may be implemented as any type of eNBB (evolved Node B) or gNB (5G base station). The eNB may include, for example, a macro eNB and a small eNB. The small eNB may be an eNB covering a cell smaller than a macro cell, such as a pico eNB, a micro eNB, or a home (femto) eNB. The same applies to gNBs. Alternatively, the base station may be implemented as any other type of base station, such as a Node B or a base transceiver station (BTS). A base station may include an entity (also referred to as base station equipment) configured to control wireless communications and one or more remote radio heads (RRHs) located at different locations from the entity. In addition, various types of user equipment may operate as a base station by temporarily or semi-permanently performing the functions of a base station.

[0094] The electronic device 200 may be realized as various user devices. The user devices may be realized as mobile terminals (e.g., smartphones, tablet personal computers (PCs), notebook PCs, portable game consoles, portable / dongle mobile routers, and digital imaging devices) or in-vehicle terminals (e.g., car navigation devices). The user devices may also be realized as terminals that perform machine-to-machine (M2M) communication (also called machine-type communication (MTC) terminals). The user devices may also be wireless communication modules (e.g., integrated circuit modules including a single chip) installed in each of these terminals.

[0095] [Application example for base stations] (First application example) 14 is a block diagram showing a first example of a schematic configuration of an eNB or gNB to which the technology of the present disclosure can be applied. The following description uses an eNB as an example, but is similarly applicable to a gNB. The eNB 800 has one or more antennas 810 and a base station device 820. The base station device 820 and each antenna 810 can be connected to each other via an RF cable.

[0096] Each of the antennas 810 has a single antenna element or multiple antenna elements (for example, multiple antenna elements included in a MIMO antenna) and is used for transmitting and receiving radio signals by the base station device 820. The eNB 800 may have multiple antennas 810 as shown in FIG. 14. The multiple antennas 810 may be compatible with, for example, multiple frequency bands used by the eNB 800. Note that although FIG. 14 shows an example in which the eNB 800 has multiple antennas 810, the eNB 800 may have a single antenna 810.

[0097] The base station device 820 includes a controller 821 , a memory 822 , a network interface 823 , and a wireless communication interface 825 .

[0098] The controller 821 may be, for example, a CPU or a DSP, and operates various upper layer functions of the base station device 820. For example, the controller 821 generates data packets from data in a signal processed by the wireless communication interface 825 and transfers the generated packets via the network interface 823. The controller 821 can generate bundled packets by bundling data from multiple baseband processors and transfer the generated bundled packets. The controller 821 can also have logical functions that perform control such as radio resource control, radio bearer control, mobility management, admission control, or scheduling. The control can be performed in cooperation with a neighboring eNB or core network node. The memory 822 includes a RAM and a ROM, and stores programs executed by the controller 821 and various control data (e.g., a terminal list, transmission power data, scheduling data, etc.).

[0099] The network interface 823 is a communication interface for connecting the base station device 820 to the core network 824. The controller 821 can communicate with a core network node or another eNB via the network interface 823. In this case, the eNB 800 and the core network node or another eNB are connected to each other by a logical interface (e.g., an S1 interface and an X2 interface). The network interface 823 may be a wired communication interface or a wireless communication interface for a wireless backhaul line. When the network interface 823 is a wireless communication interface, the network interface 823 can use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 825.

[0100] The wireless communication interface 825 supports any cellular communication system (e.g., Long Term Evolution (LTE) and LTE-Advanced) and provides wireless connection to terminals located in the eNB 800's cell via the antenna 810. The wireless communication interface 825 typically includes, for example, a baseband (BB) processor 826 and an RF circuit 827. The BB processor 826 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and can perform signal processing for each type of layer (e.g., L1, media access control (MAC), radio link control (RLC), and packet data aggregation protocol (PDCP)). The BB processor 826 may have some or all of the logical functions described above instead of the controller 821. The BB processor 826 may be a memory that stores a communication control program, or may be a module including a processor and related circuits configured to execute the program. Program updates can change the functionality of the BB processor 826. This module may be a card or board inserted into a slot in the base station device 820. Alternatively, this module may be a chip mounted on a card or board. At the same time, the RF circuitry 827 may include, for example, mixers, filters, amplifiers, and may transmit and receive radio signals via the antenna 810.

[0101] As shown in Figure 14, the wireless communication interface 825 may include multiple BB processors 826. For example, the multiple BB processors 826 may be compatible with multiple frequency bands used by the eNB 800. As shown in Figure 14, the wireless communication interface 825 may include multiple RF circuits 827. For example, the multiple RF circuits 827 may be compatible with multiple antenna elements. Although Figure 14 illustrates an example in which the wireless communication interface 825 includes multiple BB processors 826 and multiple RF circuits 827, the wireless communication interface 825 may include a single BB processor 826 or a single RF circuit 827.

[0102] 14, the transmitter 101, receiver 102, and transceiver of the electronic device 100 may be realized by a wireless communication interface 825. At least a part of the functions may be realized by a controller 821. For example, the controller 821 can notify the UE of information on the emission TRP of the downlink emission beam by executing the functions of the transmitter 101, receiver 102, and decision unit 103, thereby realizing group-based beam quality reporting and reliable simultaneous transmission of multiple beams.

[0103] (Second application example) 15 is a block diagram showing a second example of a schematic configuration of an eNB or a gNB to which the technology of the present disclosure can be applied. Similarly, the following description uses an eNB as an example, but is equally applicable to a gNB. The eNB 830 has one or more antennas 840, a base station device 850, and an RRH 860. The RRH 860 and each antenna 840 can be connected to each other via an RF cable. Furthermore, the base station device 850 and the RRH 860 can be connected to each other by a high-speed line such as an optical fiber cable.

[0104] Each of the antennas 840 has a single or multiple antenna elements (for example, multiple antenna elements included in a MIMO antenna) and is used for transmitting and receiving radio signals by the RRH 860. The eNB 830 may have multiple antennas 840 as shown in FIG. 15 . The multiple antennas 840 may be compatible with, for example, multiple frequency bands used by the eNB 830. Note that although FIG. 15 shows an example in which the eNB 830 has multiple antennas 840, the eNB 830 may also have a single antenna 840.

[0105] The base station device 850 includes a controller 851, a memory 852, a network interface 853, a wireless communication interface 855, and a connection interface 857. The controller 851, the memory 852, and the network interface 853 are similar to the controller 821, the memory 822, and the network interface 823 described with reference to FIG.

[0106] The wireless communication interface 855 supports any cellular communication method (e.g., LTE and LTE-Advanced) and provides wireless connection to terminals located in a sector corresponding to the RRH 860 via the RRH 860 and the antenna 840. The wireless communication interface 855 may typically include, for example, a BB processor 856. The BB processor 856 is similar to the BB processor 826 described with reference to FIG. 14 except that it is connected to the RF circuit 864 of the RRH 860 via a connection interface 857. The wireless communication interface 855 may include multiple BB processors 856 as shown in FIG. 15. The multiple BB processors 856 may be compatible with, for example, multiple frequency bands used by the eNB 830. Note that although FIG. 15 illustrates an example in which the wireless communication interface 855 includes multiple BB processors 856, the wireless communication interface 855 may also include a single BB processor 856.

[0107] The connection interface 857 is an interface for connecting the base station device 850 (wireless communication interface 855) to the RRH 860. The connection interface 857 may be a communication module for communication over the above-mentioned high-speed line for connecting the base station device 850 (wireless communication interface 855) to the RRH 860.

[0108] The RRH 860 includes a connection interface 861 and a wireless communication interface 863 .

[0109] The connection interface 861 is an interface for connecting the RRH 860 (wireless communication interface 863) to the base station device 850. The connection interface 861 may be a communication module for communication over the above-mentioned high-speed line.

[0110] The wireless communication interface 863 transmits and receives wireless signals via the antenna 840. The wireless communication interface 863 may typically include, for example, an RF circuit 864. The RF circuit 864 includes, for example, a mixer, a filter, and an amplifier, and is capable of transmitting and receiving wireless signals via the antenna 840. The wireless communication interface 863 may include multiple RF circuits 864 as shown in FIG. 15. The multiple RF circuits 864 can support multiple antenna elements. Note that, although FIG. 15 shows an example in which the wireless communication interface 863 includes multiple RF circuits 864, the wireless communication interface 863 may also include a single RF circuit 864.

[0111] 15, the transmitter 101, receiver 102, and transceiver of the electronic device 100 may be realized by the wireless communication interface 855 and / or the wireless communication interface 863. At least a part of the functions may be realized by the controller 851. For example, the controller 851 can notify the UE of information on the emission TRP of the downlink emission beam by executing the functions of the transmitter 101, receiver 102, and decision unit 103, thereby realizing group-based beam quality reporting and reliable simultaneous transmission of multiple beams.

The display device 910 includes a screen (e.g., a liquid crystal display (LCD), an organic light-emitting diode (OLED) display), and displays an output image of the smartphone 900. The speaker 911 converts an audio signal output from the smartphone 900 into sound.

[0115] The wireless communication interface 912 supports any cellular communication system (e.g., LTE and LTE-Advanced) and performs wireless communication. The wireless communication interface 912 typically includes, for example, a baseband processor 913 and an RF circuit 914. The baseband processor 913 can perform various types of signal processing for wireless communication, such as encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing. The RF circuit 914 can include, for example, a mixer, a filter, and an amplifier, and can transmit and receive wireless signals via an antenna 916. While the figure illustrates a case in which one RF link is connected to one antenna, this is merely an example, and a case in which one RF link is connected to multiple antennas via multiple phase shifters is also included. The wireless communication interface 912 can be a single chip module on which the baseband processor 913 and the RF circuit 914 are integrated. As shown in FIG. 16, the wireless communication interface 912 can include multiple baseband processors 913 and multiple RF circuits 914. Although FIG. 16 shows an example in which the wireless communication interface 912 includes multiple BB processors 913 and multiple RF circuits 914, the wireless communication interface 912 may include a single BB processor 913 or a single RF circuit 914.

[0116] In addition to the cellular communication system, the wireless communication interface 912 may support other types of wireless communication systems, such as a short-range wireless communication system, a proximity communication system, a wireless local network (LAN) system, etc. In this case, the wireless communication interface 912 may include a baseband processor 913 and an RF circuit 914 for various wireless communication systems.

[0117] Each of the antenna switches 915 switches the connection destination of the antenna 916 between a plurality of circuits (for example, circuits used for different wireless communication methods) included in the wireless communication interface 912.

[0118] Each of the antennas 916 includes a single antenna element or multiple antenna elements (for example, multiple antenna elements included in a MIMO antenna) and is used to transmit and receive wireless signals via the wireless communication interface 912. As shown in Fig. 16, the smartphone 900 can include multiple antennas 916. Although Fig. 16 shows an example in which the smartphone 900 includes multiple antennas 916, the smartphone 900 may also include a single antenna 916.

[0119] The smartphone 900 may include an antenna 916 for various wireless communication methods. In this case, the antenna switch 915 may be omitted from the configuration of the smartphone 900.

[0120] The bus 917 interconnects the processor 901, memory 902, storage device 903, external connection interface 904, image capture device 906, sensor 907, microphone 908, input device 909, display device 910, speaker 911, wireless communication interface 912, and auxiliary controller 919. The battery 918 supplies power to each block of the smartphone 900 shown in Fig. 16 via power supply lines, which are partially represented by dotted lines in the drawing.

At least a part of the functions may be realized by the processor 901 or the auxiliary controller 919. For example, the processor 901 or the auxiliary controller 919 can obtain information on the emission TRP of the downlink emission beam by performing the functions of the receiving unit 201, the transmitting unit 202, and the determining unit 203, thereby realizing group-based beam quality reporting and reliable simultaneous transmission of multiple beams.

The sensor 925 may include a set of sensors such as a gyro sensor, a geomagnetic sensor, and an air pressure sensor. The data interface 926 connects to, for example, an in-vehicle network 941 via a terminal (not shown) and acquires data generated by the vehicle (e.g., vehicle speed data).
