Background Art

[0004] Beamforming is a signal preprocessing technology based on antenna arrays.

[0029] Examples of the present disclosure will now be described more fully with reference to the accompanying drawings.The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

[0030] Example embodiments are provided so that the disclosure will be exhaustive and its scope will be fully conveyed to those skilled in the art. Numerous specific details such as examples of specific components, devices and methods are set forth to provide a detailed understanding of the embodiments of the present disclosure. It will be apparent to those skilled in the art that the example embodiments may be implemented in many different forms without the use of specific details, none of which should be construed as limiting the scope of the present disclosure. In certain example embodiments, well-known processes, well-known structures and well-known techniques are not described in detail.

[0031] The network side device according to the present disclosure may be any type of TRP (Transmit and Receive Port). The TRP may have sending and receiving functions, for example, it may receive information from a user device and a base station device, and it may also send information to a user device and a base station device. In one example, the TRP may provide services to the user device and be controlled by the base station device. That is, the base station device provides services to the user device through the TRP. In addition, the network side device described in the present disclosure may also be a base station device, for example, it may be an eNB (Evolved Node B) or a gNB.

[0032] The user equipment according to the present disclosure may be a mobile terminal (such as a smart phone, a tablet personal computer (PC), a notebook PC, a portable game terminal, a portable / dongle-type mobile router, and a digital camera) or a vehicle-mounted terminal (such as a car navigation device). The user equipment may also be implemented as a terminal that performs machine-to-machine (M2M) communication (also referred to as a machine type communication (MTC) terminal). In addition, the user equipment may be a wireless communication module (such as an integrated circuit module including a single chip) installed on each of the above-mentioned terminals.

[0033] Figure 1 is a block diagram showing an example of a configuration of a user equipment 100 according to an embodiment of the present disclosure.

[0034] like Figure 1 As shown, the user equipment 100 may include a selection unit 110 , a configuration unit 120 and a communication unit 130 .

[0035] Here, each unit of the user equipment 100 may be included in a processing circuit. It should be noted that the user equipment 100 may include one processing circuit or multiple processing circuits. Further, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0036] According to an embodiment of the present disclosure, the selection unit 110 may select G transmission beam groups from K transmission beams of the network side device, where K and G are both integers greater than 1. That is, the selection unit 110 may select multiple transmission beam groups from multiple transmission beams of the network side device.

[0037] According to an embodiment of the present disclosure, the K transmit beams may be all transmit beams of the network side device. For example, when the network side device has one antenna board, the K transmit beams may be all transmit beams on the antenna board; when the network side device has multiple antenna boards, the K transmit beams may be all transmit beams on multiple antenna boards. Here, the user equipment 100 may know the information about the K transmit beams in advance, for example, it may obtain the information about the K transmit beams from the network side device in advance through high-layer signaling, so that the selection unit 110 can select G transmit beam groups from the K transmit beams.

[0038] Preferably, K may be greater than or equal to G. More preferably, K may be 2 k , G can be 2 g , k and g are positive integers. For example, K can be 2, 4, 8, 16, 32 or 64, and G can be 2 or 4.

[0039] According to an embodiment of the present disclosure, each of the G transmission beam groups selected by the selection unit 110 may include N transmission beams, and the user equipment 100 may simultaneously receive downlink information sent by the network side device using the N transmission beams. That is, when the network side device uses the N transmission beams in a transmission beam group to simultaneously send downlink information to the user equipment 100, the user equipment may receive the simultaneously sent downlink information. Here, N may be an integer greater than or equal to 1, that is, each transmission beam group may include one or more transmission beams.

[0040] According to an embodiment of the present disclosure, the network side device may configure the values ​​of G and N for the user equipment 100. For example, the network side device may configure the values ​​of G and / or N for the user equipment 100 through high-layer signaling, including but not limited to RRC signaling, and may dynamically change the values ​​of G and / or N configured for the user equipment 100 through low-layer signaling, including but not limited to DCI information.

[0041] According to an embodiment of the present disclosure, the configuration unit 120 may configure information about the selected G transmit beam groups.

[0042] According to an embodiment of the present disclosure, the communication unit 130 may send information about the selected G transmit beam groups to the network side device.

[0043] It can be seen that according to the embodiments of the present disclosure, the user equipment 100 can select multiple transmission beam groups from the transmission beams of the network side device and send information about the multiple transmission beam groups to the network side device, so that multiple transmission beam groups can be reported at one time, thereby reducing signaling overhead and improving the beam selection process of the system using beamforming technology.

[0044] According to an embodiment of the present disclosure, the selection unit 110 can select G transmission beam groups based on the C transmission beam sets of the network side device, so that each transmission beam group includes N transmission beams from N transmission beam sets respectively, where C is an integer greater than or equal to N.

[0045] Here, the user equipment 100 may know in advance the information about the K transmission beams in the C transmission beam sets of the network side device, for example, the information about the K transmission beams in the C transmission beam sets may be obtained in advance from the network side device through high-layer signaling, including but not limited to the identification information of the transmission beam set to which each transmission beam belongs and the identification information of the transmission beam in the transmission beam set. Next, the selection unit 110 may select G transmission beam groups from the K transmission beams in the C transmission beam sets.

[0046] Figure 2is a schematic diagram showing selection of a transmit beam group by a user equipment according to an embodiment of the present disclosure.

[0047] exist Figure 2 In the embodiment, the gNB can be used as a network side device, and the UE can be used as a user equipment 100. Figure 2 As shown in Figure 1, the gNB has 4 transmit beam sets, that is, C = 4, each transmit beam set has 8 transmit beams, and the gNB has a total of 32 transmit beams, that is, K = 32. It is assumed here that N = 2, that is, each of the G transmit beam groups selected by the UE includes 2 transmit beams. Figure 2 As shown, the UE selects transmit beam 5 in transmit beam set 2 and transmit beam 4 in transmit beam set 3. It can be seen that the two transmit beams selected by the UE are from different transmit beam sets. Figure 2 Only one transmit beam group selected by the UE is shown in FIG. 1 . The UE may select each of the G transmit beam groups in this manner so that each transmit beam group includes two transmit beams from two transmit beam sets, respectively.

[0048] Figure 2 The transmit beam, transmit beam set, and transmit beam group are described with C=4, K=32, and N=2. Of course, the present disclosure is not limited to these specific values. Figure 2 In the embodiment, each of the four transmit beam sets has eight transmit beams, but the present disclosure is not limited thereto. That is, different transmit beam sets may have different numbers of transmit beams.

[0049] According to an embodiment of the present disclosure, each of the C transmit beam sets of the network side device may include all transmit beams emitted by one or more antenna panels of the network side device. That is, C is equal to or less than the number of antenna panels of the network side device.

[0050] According to an embodiment of the present disclosure, a transmit beam set of a network side device may correspond to one antenna board of the network side device, or may correspond to multiple antenna boards of the network side device. When each transmit beam set of the network side device corresponds to one antenna board of the network side device, C is equal to the number of antenna boards of the network side device. Figure 2Taking the example shown as an example, the gNB may have 4 antenna panels, and transmit beam set 1, transmit beam set 2, transmit beam set 3 and transmit beam set 4 respectively correspond to one of the 4 antenna panels. For example, the 8 transmit beams in transmit beam set 1 are the 8 transmit beams that can be emitted by the first antenna panel; the 8 transmit beams in transmit beam set 2 are the 8 transmit beams that can be emitted by the second antenna panel; the 8 transmit beams in transmit beam set 3 are the 8 transmit beams that can be emitted by the third antenna panel; and the 8 transmit beams in transmit beam set 4 are the 8 transmit beams that can be emitted by the fourth antenna panel. Furthermore, there may also be transmit beam sets corresponding to multiple antenna panels. At this time, C is less than the number of antenna panels of the network-side device. Still based on Figure 2 Taking the example shown as an example, the gNB may also have 5 antenna panels, transmit beam set 1 may correspond to the 1st antenna panel, transmit beam set 2 may correspond to the 2nd antenna panel, transmit beam set 3 may correspond to the 3rd antenna panel, and transmit beam set 4 may correspond to the 4th antenna panel and the 5th antenna panel. In other words, the 8 transmit beams in transmit beam set 4 are the set of all transmit beams that can be emitted by the 4th antenna panel and all transmit beams that can be emitted by the 5th antenna panel.

[0051] Figure 3 is a schematic diagram showing multiple antenna panels of a network side device according to an embodiment of the present disclosure. Figure 3 In the figure, two antenna panels of the gNB are shown, where the cross mark on each antenna panel represents a transmit beam. Figure 3 As shown, antenna board 1 has 8 transmit beams, and antenna board 2 also has 8 transmit beams.

[0052] like Figure 3 As shown, the network side device may have one or more antenna panels, and each antenna panel may have multiple transmission beams. At the same time, each antenna panel can only use one transmission beam to send downlink information. That is to say, at the same time, different antenna panels can use their own transmission beams to send downlink information. According to an embodiment of the present disclosure, the N transmission beams included in each transmission beam group selected by the selection unit 110 are respectively from N transmission beam sets, and each transmission beam set includes all transmission beams on one or more antenna panels. It can be seen that the N transmission beams included in each transmission beam group are respectively from N antenna panels, and these N antenna panels may be all antenna panels of the network side device, or may be part of the antenna panels of the network side device. In this way, the network side device can use the N transmission beams in the same transmission beam group to send downlink information at the same time, and the user equipment can receive such information at the same time, so that the beam selection process using beamforming technology can be improved, thereby improving the transmission efficiency of downlink information.

[0053] The following will describe in detail how the selection unit 110 selects G transmission beam groups from the K transmission beams in the C transmission beam sets of the network side device, where each transmission beam group includes N transmission beams.

[0054] like Figure 1 As shown, the user equipment 100 may further include a detection unit 140, which is used to detect the channel quality between the network side device and the user equipment 100. Specifically, the detection unit 140 may detect the channel quality between any one of the transmission beams of the network side device and the user equipment 100. In the present disclosure, various parameters may be used to represent the channel quality, including but not limited to: RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio), etc.

[0055] According to an embodiment of the present disclosure, the detection unit 140 can detect the channel quality between each of the K transmission beams of the network side device and the user equipment 100, and the selection unit 110 can select G transmission beam groups based on the channel quality between the K transmission beams of the network side device and the user equipment 100.

[0056] According to an embodiment of the present disclosure, the channel quality can be represented by an instantaneous value of the channel quality, or by an average value within a predetermined time period. For example, a time window can be defined, and the length of the time window in time is the predetermined time period. For any transmit beam, the detection unit 140 can detect the average value of the channel quality between the transmit beam and the user equipment 100 within the time window, and use the average value to represent the channel quality between the transmit beam and the user equipment 100. In a predetermined time period, i.e., in the time window, the user equipment 100 may scan the same transmit beam one or more times, so the channel quality between the transmit beam and the user equipment 100 may be detected one or more times. Therefore, according to an embodiment of the present disclosure, for any transmit beam, the average value of the channel quality represents the average value of the results of one or more detections of the channel quality of the transmit beam.

[0057] Figure 4 is a schematic diagram showing how to calculate channel quality based on a time window according to an embodiment of the present disclosure. Figure 4 In the time window, the length of the time window, that is, the length of the predetermined time period is τ, and t is a time on the time axis, which can be the start time of the time window defined by the detection unit 140. The beam numbered 4 in the time window represents Figure 2The transmit beam 4 in the transmit beam set 3 shown in FIG. 5 represents the beam 5. Figure 2 The transmit beam 5 in the transmit beam set 2 shown in FIG. 5 , the beam labeled 5′ indicates that the transmit beam 5 is transmitted again within the time window. Figure 2 In other words, the beam numbered 5 and the beam numbered 5' are two scans of the same transmit beam. Different numbers are used for easy distinction. According to the embodiment of the present disclosure, since Figure 4 In the time window shown, the transmit beam 4 of the transmit beam set 3 is scanned once, so the result of this measurement can be directly used as the channel detection result of the transmit beam 4 of the transmit beam set 3; Figure 4 In the time window shown, the transmit beam 5 of the transmit beam set 2 is scanned twice, so the average of the two measurement results can be used as the channel detection result of the transmit beam 5 of the transmit beam set 2. It is worth noting that for the sake of convenience, Figure 4 Only the case of two beams is shown. In fact, the detection unit 140 can determine the channel quality of each of the K transmit beams according to a similar method.

[0058] According to an embodiment of the present disclosure, the selection unit 110 can determine all transmission beam groups based on the C transmission beam sets of the network side device, determine the average channel quality of each transmission beam group based on the channel quality between the N transmission beams included in each transmission beam group and the user device 100, and select G transmission beam groups based on the average channel quality of each transmission beam group.

[0059] As mentioned above, the selection unit 110 can select G transmission beam groups according to the C transmission beam sets of the network side device, so that each transmission beam group includes N transmission beams respectively from the N transmission beam sets. According to an embodiment of the present disclosure, the selection unit 110 can determine all possible transmission beam groups according to the C transmission beam sets, and each possible transmission beam group includes N transmission beams respectively from the N transmission beam sets. In other words, the selection unit 110 can enumerate all transmission beam groups that meet the following conditions: the transmission beam group includes N transmission beams respectively from the N transmission beam sets.

[0060] According to an embodiment of the present disclosure, the selection unit 110 may also determine the average channel quality of each transmit beam group according to the channel quality between the N transmit beams included in each possible transmit beam group determined above and the user equipment 100. For example, the selection unit may use the arithmetic mean of the channel quality between the N transmit beams and the user equipment 100 as the average channel quality of the transmit beam group. Of course, other methods for calculating the average value may also be used, and the present disclosure does not limit this.

[0061] According to an embodiment of the present disclosure, the selection unit 110 may select G transmit beam groups according to the average channel quality of each transmit beam group. For example, the selection unit 110 may select the first G transmit beam groups with the best average channel quality from all possible transmit beam groups as the final G transmit beam groups.

[0062] The following will take C=2, K=8, N=2, and G=4 as an example to illustrate the selection of a transmit beam set according to channel quality. Table 1 shows the value of the channel quality of each transmit beam in the K transmit beams. In Table 1, each transmit beam set includes 4 transmit beams, so the transmit beam set number is taken from [1, 2], and the transmit beam number is taken from [1, 2, 3, 4]. In addition, in Table 1, RSRQ is taken as an example to represent the channel quality, and the 8 transmit beams are sorted according to the value of RSRQ.

[0063] Table 1

[0064] Transmit beam set number Transmit beam number RSRQ(dB) 1 2 -4.5 1 3 -5.8 2 2 -6 1 1 -6.2 2 1 -6.9 2 3 -8.3 1 4 -10.7 2 4 -11.1

[0065] According to an embodiment of the present disclosure, the selection unit 110 can determine all possible transmit beam groups. For example, when C=2, K=8, N=2, and each transmit beam group includes 4 transmit beams, 16 possible transmit beam groups can be determined, as shown in Table 2.

[0066] Table 2

[0067]

[0068]

[0069] In the transmit beam column in Table 2, two transmit beams included in each transmit beam group are shown with a semicolon as a separator. In each transmit beam, the number of the transmit beam set of the transmit beam and the number of the transmit beam in the transmit beam set are shown with a comma as a separator. For example, for a transmit beam group numbered 1, two transmit beams are included, one of which has a transmit beam set numbered 1 and a transmit beam numbered 1, and the other has a transmit beam set numbered 2 and a transmit beam numbered 1. That is, the transmit beam group numbered 1 includes transmit beam 1 in transmit beam set 1 and transmit beam 1 in transmit beam set 2.

[0070] Next, the selection unit 110 may determine the average channel quality of each of the 16 transmit beam groups in Table 2. For example, the average channel quality of the transmit beam group numbered 1 may be determined by the average of the channel quality of transmit beam 1 in transmit beam set 1 and the channel quality of transmit beam 1 in transmit beam set 2.

[0071] Next, the selection unit 110 may select the first four transmission beam groups with the best average channel quality from the 16 transmission beam groups as the final four transmission beam groups. Table 3 shows the average channel quality of the selected four transmission beam groups.

[0072] Table 3

[0073]

[0074] In the above example, the selection unit 110 can select G transmit beam groups according to the value of RSRQ. That is, the selection unit 110 selects G transmit beam groups according to only one parameter representing the channel quality. According to an embodiment of the present disclosure, the selection unit 110 can also select G transmit beam groups according to multiple parameters representing the channel quality.

[0075] According to an embodiment of the present disclosure, the selection unit 110 can determine all possible transmit beam groups from multiple transmit beams whose channel quality represented by the first parameter meets the predetermined condition, and then determine the average channel quality of each possible transmit beam group, where the average channel quality is represented by the second parameter representing the channel quality. Next, the selection unit 110 can select the first G transmit beam groups with the best average channel quality. According to an embodiment of the present disclosure, the first parameter and the second parameter can be different and can be RSRP, RSRQ, SINR, etc.

[0076] That is, the selection unit 110 may perform a first screening according to the first parameter, and a second screening according to the second parameter. For example, the selection unit 110 may select multiple transmission beams whose first parameter (e.g., RSRP) satisfies a predetermined threshold condition from the K transmission beams, and determine all possible transmission beam groups from the multiple transmission beams, and then select the first G transmission beam groups with the best second parameter (e.g., average RSRQ).

[0077] According to an embodiment of the present disclosure, the user equipment 100 may determine the transmit beam group that needs to be reported based on one or more parameters indicating the channel quality, so that the channel quality of the selected transmit beam group is better.

[0078] According to an embodiment of the present disclosure, after the selection unit 110 selects G transmit beam groups, the configuration unit 120 can configure information about the selected G transmit beam groups and report the information about the selected G transmit beam groups to the network side device through the communication unit 130.

[0079] According to an embodiment of the present disclosure, the configuration unit 120 may configure information about the selected G transmit beam groups to include: identification information of the N transmit beams included in each of the G transmit beam groups. Further, the identification information of each transmit beam may include: identification information of the transmit beam set to which the transmit beam belongs and identification information of the transmit beam in the transmit beam set.

[0080] Table 4 shows an example of information about the selected G transmit beam groups. In Table 4, G=4 and N=2. As shown in Table 4, the information about the selected G transmit beam groups includes identification information of 2 transmit beams included in each of the 4 transmit beam groups, and the identification information of each transmit beam includes identification information of the transmit beam set and identification information of the transmit beam in the transmit beam set.

[0081] Table 4

[0082]

[0083] According to an embodiment of the present disclosure, the configuration unit 120 may further configure information about the selected G transmit beam groups to include: channel quality information of all transmit beam groups in the G transmit beam groups. In addition, the channel quality information of each transmit beam group includes: the channel quality of each transmit beam in the N transmit beams included in the transmit beam group; or the average channel quality of the transmit beam group. Tables 5 and 6 show the information about the selected G transmit beam groups in these two cases, respectively. In Tables 5 and 6, G=4 and N=2. In addition, the channel quality is represented by RSRQ.

[0086] As shown in Table 5, the information about the selected G transmit beam groups includes not only identification information of the two transmit beams included in each of the four transmit beam groups, but also an average channel quality of each transmit beam group.

[0089] As shown in Table 6, the information about the selected G transmission beam groups includes not only identification information of the two transmission beams included in each of the four transmission beam groups, but also channel quality of each of the two transmission beams included in each transmission beam group.

[0090] According to an embodiment of the present disclosure, the configuration unit 120 may further configure information about the selected G transmission beam groups to include: channel quality information of some transmission beam groups among the G transmission beam groups. For example, some transmission beam groups may include a transmission beam group with the best average channel quality and a transmission beam group with the worst average channel quality among the G transmission beam groups.

[0091] Similarly, the channel quality information of each transmit beam group in the partial transmit beam group may include: the channel quality of each transmit beam in the N transmit beams included in the transmit beam group; or the average channel quality of the transmit beam group. Tables 7 and 8 show the information about the selected G transmit beam groups in these two cases, respectively. In Tables 7 and 8, G=4 and N=2. In addition, the channel quality is represented by RSRQ.

[0094] As shown in Table 7, the information about the selected G transmit beam groups includes, in addition to the identification information of the two transmit beams included in each of the four transmit beam groups, the average channel quality of the transmit beam group with the best average channel quality among the four transmit beam groups and the average channel quality of the transmit beam group with the worst average channel quality among the four transmit beam groups.

[0096] Transmit beam Average RSRQ(dB) 1,2；2,2 -4.5；-6 1,2；2,1 1,3；2,2 1,3；2,1 -5.8；-6.9

[0097] As shown in Table 8, the information about the selected G transmission beam groups includes, in addition to the identification information of the two transmission beams included in each of the four transmission beam groups, the channel quality of each transmission beam in the transmission beam group with the best average channel quality among the four transmission beam groups and the channel quality of each transmission beam in the transmission beam group with the worst average channel quality among the four transmission beam groups.

[0098] As described above, Tables 4 to 8 show five embodiments of information about the selected G transmit beam groups. According to an embodiment of the present disclosure, the user equipment 100 may also receive information about the five reporting methods from the network side device. That is, the network side device may configure a specific reporting method for the user equipment 100. Further, the user equipment 100 may also report the desired reporting method to the network side device, so that the network side device may further configure the reporting method according to the report of the user equipment 100. In addition, a default reporting method may be agreed upon between the user equipment 100 and the network side device, so that when the user equipment 100 does not receive the configured reporting method from the network side device, the default reporting method is used for reporting.

[0099] As described above, the information about the selected G transmission beam groups may include identification information of the N transmission beams included in each of the G transmission beam groups, and may also include channel quality information of all or part of the transmission beam groups in the G transmission beam groups. The network side device may configure a reporting method for the user equipment according to actual conditions, so as to clearly indicate the channel quality of each transmission beam on the basis of saving signaling overhead.

[0100] According to an embodiment of the present disclosure, the information about the selected G transmission beam groups may also include sequence information of the G transmission beam groups. Here, the sequence information may be sequence information determined according to the average channel quality of the G transmission beam groups. That is, when the user equipment 100 reports the information about the selected G transmission beam groups to the network side device, it may be reported in order from good to bad in terms of average channel quality. That is, in the examples shown in Tables 4 to 8, the order of the transmission beams listed in the table may be the order of reporting.

[0101] In addition, according to an embodiment of the present disclosure, the identifier of the transmit beam can be represented by the identifier of the CSI-RS (Channel State Information-Reference Signal) resource or the identifier of the SSB (Synchronization Signal Block) resource. This is because, for different transmit beams, different resources are used to send CSI-RS. In other words, the transmit beam corresponds to the CSI-RS resource one-to-one, so the identifier of the transmit beam can be represented by the identifier of the CSI-RS resource. Similar to sending CSI-RS, for different beams used to send SSB, different resources are used to send SSB. In other words, the transmit beam corresponds to the SSB resource one-to-one, so the identifier of the SSB resource can be used to represent the identifier of the transmit beam. Similarly, the identifier of the transmit beam set can be represented by the identifier of the CSI-RS resource set or the identifier of the SSB resource set.

[0102] Further, according to an embodiment of the present disclosure, when reporting channel quality, it can be an absolute value of the channel quality or a relative value of the channel quality. For example, the user equipment 100 can only report the absolute value of the channel quality of a transmit beam (reference transmit beam) or the absolute value of the average channel quality of a transmit beam group (reference transmit beam group), while for the channel quality of other transmit beams, or for the average channel quality of other transmit beam groups, only the relative value relative to the reference transmit beam or relative to the reference transmit beam group can be reported. In this way, the signaling overhead can be further saved.

[0103] As described above, the configuration unit 120 may configure the information about the selected G transmit beam groups. Thereafter, the information about the selected G transmit beam groups may be sent to the network side device through the communication unit 130.

[0104] According to an embodiment of the present disclosure, the user equipment 100 may use a CSI (Channel State Information) report to carry the information about the selected G transmit beam groups. That is, the user equipment 100 may report the information about the selected G transmit beam groups at one time (i.e., simultaneously).

[0105] Table 9 shows an embodiment of a CSI report. In Table 9, it is assumed that N=2 and G=2.

[0106] Table 9

[0107]

[0108] As shown in Table 9, n represents the number of the CSI report. The content of the CSI report may include identification information of 4 transmit beams in 2 transmit beam groups. Among them, CSI-RS resource set identifier or SSB resource set identifier #1, the transmit beam represented by the CSI-RS resource identifier or SSB resource identifier #1 and the transmit beam represented by the CSI-RS resource set identifier or SSB resource set identifier #2, the transmit beam represented by the CSI-RS resource identifier or SSB resource identifier #2 are one transmit beam group, and the CSI-RS resource set identifier or SSB resource set identifier #3, the transmit beam represented by the CSI-RS resource identifier or SSB resource identifier #3 and the CSI-RS resource set identifier or SSB resource set identifier #4, the transmit beam represented by the CSI-RS resource identifier or SSB resource identifier #4 are another transmit beam group. In addition, when necessary, the content of the CSI report may also include channel quality information of all or part of the 4 transmit beams.

[0109] According to an embodiment of the present disclosure, the number of the transmit beam group may not be reported. This is because, in the CSI report, the identification information of all transmit beams included in the G transmit beam groups is reported in sequence. That is, in the example shown in Table 9, the first two transmit beams are one transmit beam group, and the last two transmit beams are another transmit beam group. Further, the network side device can configure the values ​​of G and N, that is, the network side device knows the values ​​of G and N, and therefore can determine the transmit beams included in each transmit beam group according to the content of the CSI report. In this way, the overhead of the CSI report can be further saved. In addition, Table 9 only shows an example of reporting the channel quality information of the transmit beams included in the transmit beam group. As described above, the CSI report may include the average channel quality information of the transmit beam group.

[0110] According to an embodiment of the present disclosure, after the user equipment 100 reports information about the selected G transmit beam groups to the network side device, control information may be received from the network side device through the communication unit 130 .

[0111] like Figure 1 As shown, according to an embodiment of the present disclosure, the user equipment 100 may further include a determination unit 150, which is used to determine a transmission beam group or a transmission beam selected by the network side device for sending downlink information according to the received control information.

[0112] According to an embodiment of the present disclosure, after the user equipment 100 reports information about the G transmission beam groups, the network side device may select a transmission beam group from the G transmission beam groups, thereby using multiple transmission beams in the transmission beam group to simultaneously send downlink information. Further, the network side device may also select a transmission beam in a transmission beam group from the G transmission beam groups, thereby only using the transmission beam to send downlink information.

[0113] According to an embodiment of the present disclosure, the downlink information sent by the network side device using one transmit beam or one transmit beam group may include downlink control information and downlink data information. The following will describe the downlink control information and downlink data information.

[0114] According to an embodiment of the present disclosure, the communication unit 130 may receive control information through DCI (Downlink Control Information), and the determination unit 150 may demodulate the transmission beam group or transmission beam selected by the network side device for sending downlink data information from the DCI. That is, the determination unit 150 may determine the transmission beam group or transmission beam carrying the PDSCH channel according to the DCI.

[0115] According to an embodiment of the present disclosure, the communication unit 130 may also receive control information through MAC (medium access control) layer signaling, including but not limited to MAC CE (Control Element), and the determination unit 150 may demodulate the transmission beam group or transmission beam selected by the network side device for sending downlink control information from the MAC CE. That is, the determination unit 150 may determine the transmission beam group or transmission beam carrying the PDCCH channel according to the MAC CE.

[0116] The following will further explain the two cases of the network side device selecting a transmit beam and the network side device selecting a transmit beam group.

[0117] In the case where the network side device selects a transmit beam group, the determination unit 150 can demodulate the identifier (i.e., number) of the transmit beam group used to send downlink data information from the DCI. Further, the determination unit 150 can demodulate the identifier (i.e., number) of the transmit beam group used to send downlink control information from the MAC CE. In other words, the DCI carries the number of the transmit beam group used to send downlink data information, and the MAC CE carries the number of the transmit beam group used to send downlink control information.

[0118] As mentioned above, the information about the G transmit beam groups may not include the number information of the transmit beam groups. Therefore, when the determination unit 150 demodulates the number of the transmit beam group, it can determine which transmit beam group the network side device selects according to the order of the reported G transmit beam groups. For example, in the example shown in Table 9, when the determination unit 150 demodulates the transmit beam group number as 1, it can be determined that the network side device selects a group including the following transmit beams: CSI-RS resource set identifier or SSB resource set identifier #1, CSI-RS resource identifier or SSB resource identifier #1; and CSI-RS resource set identifier or SSB resource set identifier #2, CSI-RS resource identifier or SSB resource identifier #2; and when the determination unit 150 demodulates the transmit beam group number as 2, it can be determined that the network side device selects a group including the following transmit beams: CSI-RS resource set identifier or SSB resource set identifier #3, CSI-RS resource identifier or SSB resource identifier #3; and CSI-RS resource set identifier or SSB resource set identifier #4, CSI-RS resource identifier or SSB resource identifier #4.

[0119] According to an embodiment of the present disclosure, after the determination unit 150 determines the transmission beam group used by the network side device to send downlink control information or downlink data information, the corresponding reception beam can be used for reception.

[0120] In the case where the network side device selects a transmit beam, the determination unit 150 can demodulate TCI (Transmission Configuration Indication) status information from the DCI or MAC CE, and determine the transmit beam used to send downlink data information or to send downlink control information according to the TCI status information. Specifically, the determination unit 150 can demodulate the TCI status information from the DCI, and extract identification information of the transmit beam used to send downlink data information from the TCI status information, including an identification of the transmit beam set to which the transmit beam belongs, such as a CSI-RS resource set identification or an SSB resource set identification; and an identification of the transmit beam in the transmit beam set, such as a CSI-RS resource identification or an SSB resource identification. The determination unit 150 can demodulate the TCI status information from the MAC CE, and extract the identification information of the transmit beam used to send downlink control information from the TCI status information, including the identifier of the transmit beam set in which the transmit beam is located, such as the CSI-RS resource set identifier or the SSB resource set identifier; and the identifier of the transmit beam in the transmit beam set, such as the CSI-RS resource identifier or the SSB resource identifier.

[0121] According to an embodiment of the present disclosure, after the determination unit 150 determines the transmission beam used by the network side device to send downlink control information or downlink data information, the corresponding reception beam can be used for reception.

[0122] It can be seen that according to the user equipment 100 of the embodiment of the present disclosure, multiple transmission beam groups can be selected from the transmission beams of the network side device and information about the multiple transmission beam groups can be sent to the network side device, so that multiple transmission beam groups can be reported at one time, thereby reducing signaling overhead. Further, in the process of selecting the transmission beam by the user equipment 100, one or more parameters representing the channel quality can be used, so that the channel quality of the selected transmission beam group is better. In summary, according to the user equipment 100 of the embodiment of the present disclosure, the beam selection process of the system using beamforming technology can be improved.

[0123] Figure 5 1 is a block diagram showing the structure of an electronic device 500 used as a network side device in a wireless communication system according to an embodiment of the present disclosure. Figure 5 As shown, the electronic device 500 may include a selection unit 510 and a communication unit 520 .

[0124] Here, each unit of the electronic device 500 may be included in a processing circuit. It should be noted that the electronic device 500 may include one processing circuit or multiple processing circuits. Further, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0125] According to an embodiment of the present disclosure, the communication unit 520 may receive information about G transmit beam groups from the user equipment.

[0126] According to an embodiment of the present disclosure, the selection unit 510 may select a transmission beam group or a transmission beam for sending downlink information from G transmission beam groups.

[0127] Here, each of the G transmit beam groups includes N transmit beams, and the user equipment can simultaneously receive downlink information sent by the electronic device 500 using the N transmit beams, and wherein N and G are both integers greater than 1.

[0128] It can be seen that according to the electronic device 500 of an embodiment of the present disclosure, a suitable transmit beam group or transmit beam can be selected from the information about multiple transmit beam groups sent by the user equipment, thereby making the selected transmit beam group more reasonable, thereby improving the beam selection process of the system using beamforming technology.

[0129] According to an embodiment of the present disclosure, the electronic device 500 can configure the values ​​of G and N for the user equipment. For example, the electronic device 500 can configure the values ​​of G and / or N for the user equipment 100 through high-layer signaling, including but not limited to RRC signaling, and can dynamically change the values ​​of G and / or N configured for the user equipment through low-layer signaling, including but not limited to DCI information.

[0130] According to an embodiment of the present disclosure, the electronic device 500 may also send information about the K transmit beams and the C transmit beam sets to the user equipment, so that the user equipment selects G transmit beam groups from the K transmit beams in the C transmit beam sets. For example, the electronic device 500 may send information about the K transmit beams and the C transmit beam sets to the user equipment through high-layer signaling.

[0131] like Figure 5 As shown, according to an embodiment of the present disclosure, the electronic device 500 may further include a demodulation unit 530, configured to demodulate information about the G transmit beam groups received from the user equipment.

[0132] According to an embodiment of the present disclosure, the demodulation unit 530 may demodulate the information about the G transmit beam groups, thereby determining the identification information of the N transmit beams included in each of the G transmit beam groups. Here, the identification information of each transmit beam may include: the identification information of the transmit beam set to which the transmit beam belongs and the identification information of the transmit beam in the transmit beam set.

[0133] According to an embodiment of the present disclosure, the demodulation unit 530 may also demodulate the information about the G transmit beam groups, so as to determine the channel quality information of all or part of the transmit beam groups in the G transmit beam groups. Here, the channel quality information of each transmit beam group in all or part of the transmit beam groups may include: the channel quality of each transmit beam in the N transmit beams included in the transmit beam group; or the average channel quality of the transmit beam group.

[0134] According to an embodiment of the present disclosure, the demodulation unit 530 may also demodulate information about the G transmit beam groups to determine the order of the G transmit beam groups. For example, the electronic device 500 may agree with the user equipment that the G transmit beam groups are ordered from best to worst according to the average channel quality of the G transmit beam groups.

[0135] According to an embodiment of the present disclosure, the electronic device 500 may also configure a reporting method for the user equipment, that is, configure what information the information about the G transmit beam groups includes for the user equipment. For example, the electronic device 500 can select one reporting method from the following five reporting methods: reporting identification information of the N transmission beams included in each of the G transmission beam groups; reporting identification information of the N transmission beams included in each of the G transmission beam groups and the average channel quality of all the transmission beam groups in the G transmission beam groups; reporting identification information of the N transmission beams included in each of the G transmission beam groups and the channel quality of each of the N transmission beams included in all the transmission beam groups in the G transmission beam groups; reporting identification information of the N transmission beams included in each of the G transmission beam groups and the average channel quality of some of the transmission beam groups in the G transmission beam groups; and reporting identification information of the N transmission beams included in each of the G transmission beam groups and the channel quality of each of the N transmission beams included in some of the G transmission beam groups. Furthermore, the electronic device 500 may also receive a reporting mode expected by the user equipment from the user equipment, and then configure the reporting mode for the user equipment according to actual conditions.

[0136] According to an embodiment of the present disclosure, the electronic device 500 may receive one CSI report from the user equipment to obtain information about G transmit beam groups. That is, the information about the G transmit beam groups is received once (ie, simultaneously) in one CSI report.

[0137] According to an embodiment of the present disclosure, the selection unit 510 may select a suitable transmission beam group or a suitable transmission beam according to the information demodulated by the demodulation unit 530. That is, the selection unit 510 may select a transmission beam group to simultaneously send downlink information to the user equipment using the N transmission beams included in the transmission beam group. Further, the selection unit 510 may also select a transmission beam in a transmission beam group to send downlink information to the user equipment using the transmission beam.

[0138] According to an embodiment of the present disclosure, the selection unit 510 may select a transmission beam group with the best average channel quality, or may select a transmission beam with the best channel quality. Of course, the present disclosure is not limited thereto, and the selection unit 510 may also select a suitable transmission beam group or transmission beam by, for example, considering configuration information of a neighboring cell for a transmission beam.

[0139] According to an embodiment of the present disclosure, after the selection unit 510 selects a suitable transmit beam or transmit beam group, it is necessary to notify the user equipment of the selected transmit beam or transmit beam group. The electronic device 500 may carry information about the transmit beam or transmit beam group through control information.

[0140] like Figure 5 As shown, according to an embodiment of the present disclosure, the electronic device 500 may further include a configuration unit 540 for configuring control information, wherein the control information includes information about a selected transmission beam group or a transmission beam for sending downlink information. Further, the electronic device 500 may send the control information to the user equipment through the communication unit 520.

[0141] According to an embodiment of the present disclosure, the downlink information that the electronic device 500 can send using one transmit beam or one transmit beam group may include downlink control information and downlink data information. The following will describe the downlink control information and downlink data information.

[0142] According to an embodiment of the present disclosure, the configuration unit 540 may use DCI to carry control information, where the control information carries information about a selected transmit beam group or transmit beam for sending downlink data information.

[0143] According to an embodiment of the present disclosure, the configuration unit 540 may utilize MAC layer signaling, including but not limited to MAC CE, to carry control information, where the control information includes information about a selected transmit beam group or transmit beam for sending downlink control information.

[0144] The following will further describe two cases in which the electronic device 500 selects a transmit beam and the electronic device 500 selects a transmit beam group.

[0145] When the electronic device 500 selects a transmit beam group, the configuration unit 540 may use DCI format 1_1 to carry control information about the selected transmit beam group for sending downlink data information. Specifically, the control information may include an identifier of the selected transmit beam group for sending downlink control information.

[0146] As mentioned above, the information about the G transmit beam groups received by the electronic device 500 may not include the number information of the transmit beam groups, and the electronic device 500 may determine the number (i.e., the identifier) ​​of the transmit beam group according to the order of the reported G transmit beam groups. For example, in the example shown in Table 9, when the electronic device 500 receives the following transmit beams in sequence: CSI-RS resource set identifier or SSB resource set identifier #1, CSI-RS resource identifier or SSB resource identifier #1; CSI-RS resource set identifier or SSB resource set identifier #2, CSI-RS resource identifier or SSB resource identifier #2; CSI-RS resource set identifier or SSB resource set identifier #3, CSI-RS resource identifier or SSB resource identifier #3; and CSI-RS resource set identifier or SSB resource set identifier #4, CSI-RS resource identifier or SSB resource identifier #4, it can be determined that the first two are one transmit beam group, and the latter two are one transmit beam group. Therefore, the electronic device 500 can determine that the transmission beam group composed of the first two is numbered 1, and the transmission beam group composed of the last two is numbered 2. Therefore, when the electronic device 500 selects the transmission beam group numbered 1, the number 1 can be encoded into the control information, and when the electronic device 500 selects the transmission beam group numbered 2, the number 2 can be encoded into the control information.

[0147] According to an embodiment of the present disclosure, DCI format 1_1 may be modified to include a GBBI (Group based beamindication), which indicates the number of the transmit beam group selected by the electronic device 500 for sending downlink data information. For example, the number of the transmit beam group may be represented by binary, and the number of bits of the binary may be determined according to the size of G. For example, when G=4, the GBBI may be represented by 2 bits. The code of the modified DCI format 1_1 is as follows, wherein the use of 2 bits to represent the number of the transmit beam group is merely exemplary.

[0148] The DCI format 1_1with CRC scrambled by C-RNTI(TS 38.212)

[0149] -Carrier indicator-–0or 3bits

[0150] …

[0151] Group based beamindication(GBBI)--beam group id,2bits.

[0152] …

[0153] In the case where the electronic device 500 selects a transmit beam group, the configuration unit 540 may use the MAC CE to carry control information about the selected transmit beam group for sending downlink control information. Specifically, the control information may include an identifier of the selected transmit beam group for sending downlink control information. Similarly, the MAC CE may be modified to include a GBBI (Group based beam indication), which indicates the number of the transmit beam group selected by the electronic device 500 for sending downlink control information.

[0154] In the case where the electronic device 500 selects a transmit beam, the configuration unit 540 may use DCI or MAC CE to carry TCI status information, and the TCI status information includes a transmit beam used to send downlink data information or a transmit beam used to send downlink control information. Specifically, the configuration unit 540 may configure the TCI status information included in the DCI to carry identification information of the transmit beam used to send downlink data information, including an identifier of the transmit beam set in which the transmit beam is located, such as a CSI-RS resource set identifier or an SSB resource set identifier, and an identifier of the transmit beam in the transmit beam set, such as a CSI-RS resource identifier or an SSB resource identifier. Further, the configuration unit 540 may configure the TCI status information included in the MAC CE to carry identification information of the transmit beam used to send downlink control information, including an identifier of the transmit beam set in which the transmit beam is located, such as a CSI-RS resource set identifier or an SSB resource set identifier; and an identifier of the transmit beam in the transmit beam set, such as a CSI-RS resource identifier or an SSB resource identifier.

[0155] The code of the modified TCI status information is as follows: NZP-CSI-RS-Resource-SetId indicates the identifier of the transmit beam set to which the transmit beam is located, that is, the CSI-RS resource set identifier, and NZP-CSI-RS-ResourceId indicates the identifier of the transmit beam in the transmit beam set, that is, the CSI-RS resource identifier.

[0156]

[0157] As described above, the configuration unit 540 can use DCI or MAC CE to carry information about the selected transmit beam group or transmit beam for sending downlink information, so that the user equipment can know the transmit beam group or transmit beam to be used by the network side device, and thus select a suitable receive beam.

[0158] According to an embodiment of the present disclosure, when the electronic device 500 selects a transmit beam group, since the multiple transmit beams in the transmit beam group are located on different antenna panels of the electronic device 500, the electronic device 500 can use the multiple transmit beams in the transmit beam group to simultaneously send downlink information to the user device, thereby improving the transmission efficiency.

[0159] It can be seen that according to the electronic device 500 of the embodiment of the present disclosure, a suitable transmission beam group or transmission beam can be selected from the information about multiple transmission beam groups sent by the user equipment, thereby making the selected transmission beam group more reasonable. In addition, the electronic device 500 can also configure one of multiple reporting methods for the user equipment. Further, the electronic device 500 can use multiple transmission beams in the transmission beam group to simultaneously send downlink information to the user equipment, thereby improving the transmission efficiency. In summary, according to the electronic device 500 of the embodiment of the present disclosure, the beam selection process of the system using beamforming technology can be improved.

[0160] According to an embodiment of the present disclosure, the electronic device 500 can be used as a network-side device, that is, the electronic device 500 can provide services for the user device 100, so all the embodiments described above regarding the user device 100 are applicable hereto.

[0161] Next, a wireless communication method performed by the user equipment 100 in a wireless communication system according to an embodiment of the present disclosure will be described in detail.
