Description

User equipment, electronic equipment, wireless communication method, and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on April 1, 2022, with application number 202210339010.2 and invention name “User Equipment, Electronic Device, Wireless Communication Method and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] Embodiments of the present disclosure generally relate to the field of wireless communications, and more particularly, to user equipment, electronic devices, wireless communication methods, and computer-readable storage media. More particularly, the present disclosure relates to a user equipment in a wireless communication system, an electronic device serving as a network-side device in the wireless communication system, a wireless communication method performed by the user equipment in the wireless communication system, a wireless communication method performed by the network-side device in the wireless communication system, and a computer-readable storage medium. Background Art

[0003] The user equipment can be equipped with multiple antenna panels, referred to as panels, to cover multiple different directions. For example, each panel of the user equipment faces one direction and sends one or more beams. The user equipment can use the user capability value set (UE capability value set) to report multiple panels of the user equipment to the network side device, and each user capability value set corresponds to a panel. The user capability value set may include one or more user capability values. However, the existing protocol stipulates that the user equipment cannot report two user capability value sets with the same user capability value. In other words, if the user equipment has two panels, and the user capability values ​​in the user capability value sets of these two panels are the same, the user equipment cannot report these two panels to the network side device at the same time, that is, the network side device cannot schedule these two panels at the same time. This greatly limits the application scenario of scheduling multiple panels in uplink transmission.

[0004] Furthermore, in existing protocols, in scenarios where a user device (UE) is equipped with multiple antenna panels, there is no definitive solution for whether and how the network should send feedback after the UE reports beam quality information to the network. Furthermore, when the network schedules multiple panels for uplink transmission of the UE, implementing uplink scheduling is another technical issue that needs to be addressed.

[0005] Therefore, it is necessary to propose a technical solution to optimize the multi-panel uplink transmission process of the user equipment.

[0006] Summary of the Invention

[0007] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0008] The present disclosure aims to provide a user equipment, an electronic device, a wireless communication method, and a computer-readable storage medium to optimize a multi-panel uplink transmission process of the user equipment.

[0009] According to one aspect of the present disclosure, a user device is provided, comprising a processing circuit configured to: generate panel information, the panel information comprising a set of user capability values ​​for each of a plurality of panels of the user device, wherein the user capability values ​​in the user capability value sets of different panels are the same or different; and send the panel information to a network side device.

[0010] According to another aspect of the present disclosure, an electronic device is provided, comprising a processing circuit configured to: receive panel information from a user device; and determine a user capability value set for each of a plurality of panels of the user device based on the panel information, wherein the user capability values ​​in the user capability value sets of different panels are the same or different.

[0011] According to another aspect of the present disclosure, a wireless communication method performed by a user device is provided, comprising: generating panel information, the panel information comprising a set of user capability values ​​for each of a plurality of panels of the user device, wherein the user capability values ​​in the user capability value sets of different panels are the same or different; and sending the panel information to a network side device.

[0012] According to another aspect of the present disclosure, a wireless communication method performed by an electronic device is provided, including: receiving panel information from a user device; and determining a user capability value set for each of a plurality of panels of the user device based on the panel information, wherein the user capability values ​​in the user capability value sets of different panels are the same or different.

[0013] According to another aspect of the present disclosure, a computer-readable storage medium is provided, comprising executable computer instructions, which, when executed by a computer, enable the computer to perform the wireless communication method according to the present disclosure.

[0014] According to another aspect of the present disclosure, a computer program is provided. When the computer program is executed by a computer, the computer is caused to perform the wireless communication method according to the present disclosure.

[0015] Using the user equipment, electronic device, wireless communication method, and computer-readable storage medium disclosed herein, the panel information reported by the user equipment can have the same or different user capability values ​​in user capability value sets for different panels. This eliminates the restriction that prevents a user equipment from reporting two panels with the same user capability value, thereby removing the restriction on multi-panel uplink transmission. This allows the user equipment to report to any panel, thereby optimizing the multi-panel uplink transmission process of the user equipment.

[0032] 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.

[0033] Example embodiments are provided so that the present disclosure will be exhaustive and will fully convey its scope 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.

In some example embodiments, well-known processes, well-known structures, and well-known technologies are not described in detail.

[0034] The description will be in the following order:

[0035] 1. Description of the problem;

[0036] 2. User equipment configuration example;

[0037] 3. Configuration example of network-side equipment;

[0038] 4. Method embodiment;

[0039] 5. Application examples.

[0040] <1. Description of the problem>

[0041] As mentioned earlier, existing protocols prohibit user equipment from reporting two sets of user capability values ​​with the same value, significantly limiting the application scenarios for scheduling multiple panels during uplink transmission. Furthermore, existing protocols do not specify which antenna panel parameters should be used as the user capability values ​​in the set. Furthermore, existing protocols do not define whether and how the network should send feedback after the user equipment reports beam quality information to the network. Furthermore, existing protocols lack details on how to implement scheduling multiple panels during uplink transmission.

[0042] Aiming at such a scenario, the present disclosure proposes an electronic device in a wireless communication system, a wireless communication method performed by the electronic device in the wireless communication system, and a computer-readable storage medium to optimize a multi-panel uplink transmission process of a user equipment.

[0043] The wireless communication system according to the present disclosure may be a 5G NR communication system or a 6G or higher level communication system.

[0044] The network side device according to the present disclosure may be a base station device, for example, an eNB or a gNB (a base station in a 5th generation communication system).

[0045] The user equipment according to the present disclosure may be a mobile terminal (such as a smartphone, a tablet personal computer (PC), a notebook PC, a portable game terminal, a portable / dongle-type mobile router, and a digital camera) or an in-vehicle 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 known 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. In addition, the user equipment according to the present disclosure may be equipped with multiple antenna panels.

[0046] <2. User Equipment Configuration Example>

[0047] FIG. 1 is a block diagram illustrating an example of a configuration of a user equipment 100 according to an embodiment of the present disclosure.

[0048] As shown in FIG. 1 , the user equipment 100 may include a generating unit 110 and a communicating unit 120 .

[0049] Here, each unit of user equipment 100 may be included in a processing circuit. It should be noted that user equipment 100 may include either one processing circuit or multiple processing circuits. Furthermore, 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 or logical entities, and units with different names may be implemented by the same physical entity.

[0050] According to an embodiment of the present disclosure, the generation unit 110 may generate panel information. Here, the panel information may include a user capability value set for each of the multiple panels of the user equipment 100. Furthermore, the user capability values ​​(UE capability values) in the user capability value sets of different panels may be the same or different.

[0051] According to an embodiment of the present disclosure, the user equipment 100 may send panel information to the network side device through the communication unit 120. The network side device here may be a network side device that provides services for the user equipment 100.

[0052] Thus, according to the embodiment of the present disclosure, the user equipment 100 reports panel information, and the user capability values ​​in the user capability value sets of different panels may be the same or different. In other words, the present disclosure removes the restriction that the user equipment cannot report two panels with the same user capability value, i.e., removes the restriction on multi-panel uplink transmission, thereby enabling the user equipment to report any panel, thereby optimizing the multi-panel uplink transmission process of the user equipment.

[0053] According to an embodiment of the present disclosure, as shown in FIG1 , the user equipment 100 may further include a coherence type determining unit 130, configured to determine an intra-panel coherence type for each of all panels of the user equipment 100. Furthermore, the generating unit 110 may include the intra-panel coherence type as a user capability value in the user capability value set for the panel.

[0054] According to an embodiment of the present disclosure, the intra-panel coherence type represents a coherence condition between multiple ports of the panel, and the coherence condition between multiple ports of the panel includes complete coherence, partial coherence, and incoherence.

[0055] According to an embodiment of the present disclosure, when any two SRS ports among all the SRS ports of the panel are coherent, the coherence type determination unit 130 can determine that the intra-panel coherence type of the panel is fully coherent. Here, the coherence of two SRS ports means that the phase difference between the two SRS ports is constant, so the two SRS ports can use the same precoding matrix. That is, in the case of full coherence, all SRS ports of the panel use the same precoding matrix. For example, panel A has 4 SRS ports, numbered 1-4, and any two SRS ports of these 4 SRS ports are coherent, that is, the 4 SRS ports use the same precoding matrix a, then the intra-panel coherence type of panel A is fully coherent.

[0056] According to an embodiment of the present disclosure, when any two SRS ports among all the SRS ports of the panel are incoherent, the coherence type determination unit 130 can determine that the intra-panel coherence type of the panel is incoherent. Here, the incoherence of the two SRS ports means that the phase difference between the two SRS ports is non-constant, that is, it changes with time, so the two SRS ports use different precoding matrices. That is, in the case of incoherence, all SRS ports of the panel use different precoding matrices. For example, panel B has 4 SRS ports, numbered 1-4, and any two SRS ports of these 4 SRS ports are incoherent, that is, the 4 SRS ports use different precoding matrices a, b, c and d, respectively, then the intra-panel coherence type of panel B is incoherent.

[0057] According to an embodiment of the present disclosure, if there are partially coherent SRS ports among all SRS ports of a panel, the coherence type determination unit 130 may determine that the intra-panel coherence type of the panel is partially coherent. That is, in the case of partial coherence, some of the SRS ports of the panel use the same precoding matrix. For example, if panel C has four SRS ports, numbered 1-4, and ports 1 and 2 of these four SRS ports are coherent and use the same precoding matrix a, port 3 uses precoding matrix b, and port 4 uses precoding matrix c, then the intra-panel coherence type of panel C is partially coherent.

[0058] According to an embodiment of the present disclosure, when multiple ports of a panel are partially coherent, the coherence information between the multiple ports of the panel also includes the partially coherent ports. For example, when ports 1 and 2 of panel C are coherent, the coherence information between the multiple ports of the panel may also include information indicating that ports 1 and 2 are coherent. That is, the user capability value includes not only the information indicating the partial coherence, but also the partially coherent ports of the panel.

[0059] According to an embodiment of the present disclosure, the user capability value may also include the number of SRS ports. That is, the generation unit 110 may include the number of SRS ports of a panel as a user capability value in the user capability value set for that panel. In other words, the user capability value set for each panel may include two user capability values: the number of SRS ports and the intra-panel coherence type.

[0060] According to an embodiment of the present disclosure, the user capability value set of each panel may include one or more user capability values. The user capability values ​​in the user capability value sets of two panels being the same means that all user capability values ​​in the user capability value sets of the two panels are the same; otherwise, the user capability values ​​in the user capability value sets of the two panels are different. In addition, according to an embodiment of the present disclosure, when the user capability values ​​in the user capability value sets of two panels are the same, it can also be said that the user capability value sets of the two panels are the same.

[0061] That is, when the user capability value set of each panel includes the number of SRS ports and the intra-panel coherence type, if the two user capability values ​​of the number of SRS ports and the intra-panel coherence type of the two panels are the same, the user capability value sets of the two panels are the same; otherwise, the user capability value sets of the two panels are different. For example, panel D and panel E have the same number of SRS ports, the intra-panel coherence type of panel D is partial coherence, where ports 1 and 2 are coherent, and ports 3 and 4 are coherent, and the intra-panel coherence type of panel E is partial coherence, where ports 1 and 4 are coherent, and ports 2 and 3 are coherent, then the user capability value sets of panel D and panel E are different. For another example, panel F and panel G have the same number of SRS ports, the intra-panel coherence type of panel F is full coherence, and the intra-panel coherence type of panel G is full coherence, then the user capability value sets of panel F and panel G are the same.

[0062] As described above, according to embodiments of the present disclosure, the number of SRS ports of a panel and / or the coherence type within the panel can be used as user capability values ​​and thus included in the user capability value set of the panel. That is, the present disclosure defines two parameters that can be used as user capability values.

[0063] According to an embodiment of the present disclosure, after determining the user capability value set of each panel among all panels of the user equipment 100 as described above, the generation unit 110 may include the user capability value set of each panel in the panel information.

[0064] It can be seen that according to the embodiments of the present disclosure, regardless of whether the user capability value sets are the same, the user equipment can report the panel to the network side device, that is, the network side has no restrictions when scheduling multiple panels.

[0065] According to an embodiment of the present disclosure, after reporting the panel information, the user equipment 100 may receive RRC configuration information from the network side device through the communication unit 120 .

[0066] According to an embodiment of the present disclosure, as shown in FIG1 , the user equipment 100 may further include a measurement unit 140 for measuring the channel quality of each beam based on a reference signal from a network-side device. Here, the user equipment 100 may be equipped with multiple panels, each panel including one or more beams, so that the measurement unit 140 can measure the channel quality of each beam of each panel.

[0067] This disclosure does not impose any restrictions on the parameters that represent channel quality. For example, L1-RSRP (Lay 1-Reference Signal Receiving Power) or L1-SINR (Lay 1-Signal to Interference plus Noise Ratio) can be used to represent the channel quality of each beam.

[0068] According to an embodiment of the present disclosure, as shown in FIG1 , the user equipment 100 may further include a selection unit 150 for selecting a preferred beam for each panel, that is, selecting a beam with the best channel quality for each panel.

[0069] According to an embodiment of the present disclosure, the generation unit 110 may also generate beam quality information for each panel, where the beam quality information includes the preferred beam of the panel, so that the user equipment 100 may send the beam quality information to the network side device through the communication unit 120 .

[0070] According to an embodiment of the present disclosure, the preferred beam of the panel can be represented by panel indication information and beam indication information. Furthermore, since there is a one-to-one correspondence between the panel and the user capability value set, the panel indication information can be represented by the identification information of the user capability value set (UE capability value set ID). In addition, since there is a one-to-one correspondence between the downlink reference signal of the network side device and the beam, the beam indication information can be represented by CRI (CSI-RS resource indicator) or SSBRI (SSB (Synchronization Signal block) resource indicator). That is, the beam quality information of each panel may include panel indication information and beam indication information.

[0071] According to an embodiment of the present disclosure, the coherence type determination unit 130 may further determine an inter-panel coherence type for each panel, and the generation unit 110 may include the inter-panel coherence type in the beam quality information.

[0072] According to an embodiment of the present disclosure, the inter-panel coherence type of a panel may represent a coherence situation between the panel and other panels, and the coherence situation between the panel and other panels includes incoherence and coherence.

[0073] According to an embodiment of the present disclosure, if the intra-panel coherence type of panel X is fully coherent, the intra-panel coherence type of panel Y is fully coherent, and the phase difference between each port of panel X and each port of panel Y is constant, then the inter-panel coherence type of panel X is coherent, and the inter-panel coherence type of panel Y is coherent. In this case, each port of panel X and each port of panel Y can use the same precoding matrix.

[0074] For each panel, the coherence type determination unit 130 can determine whether there are other panels in the user device 100 that are coherent with the panel. If there are no other panels that are coherent with the panel, the inter-panel coherence type of the panel is incoherent. If there are other panels that are coherent with the panel, the inter-panel coherence type of the panel is coherent. Further, in the case where there are other panels that are coherent with the panel, the coherence between the panel and the other panels also includes information about the other panels that are coherent with the panel. For example, the identification information of the user capability value set can be used to represent the other panels. For example, when panel X is coherent with panel Y, the inter-panel coherence type of panel X is coherent, and the inter-panel coherence type of panel X includes information about panel Y; the inter-panel coherence type of panel Y is coherent, and the inter-panel coherence type of panel Y includes information about panel X.

[0075] According to an embodiment of the present disclosure, the generation unit 110 may further include channel quality information of the preferred beam of the panel in the beam quality information. The channel quality information includes but is not limited to L1-RSRP and L1-SINR.

[0076] As described above, the generation unit 110 may generate beam quality information for each panel, and the beam quality information may include one or more of the following: the inter-panel coherence type of the panel; the preferred beam of the panel; and the channel quality information of the preferred beam of the panel.

[0077] As described above, according to the embodiments of the present disclosure, when reporting beam quality information to the network device, the user equipment 100 can report the inter-panel coherence type. Furthermore, when reporting panel information to the network device, the user equipment 100 can also report the intra-panel coherence type. This facilitates the network device to schedule the panel for uplink transmission for the user equipment 100 and determine the precoding matrix for each panel based on the intra-panel coherence type and inter-panel coherence type of each panel.

[0078] According to an embodiment of the present disclosure, after the user equipment 100 sends the beam quality information to the network side device, the user equipment 100 may receive feedback information regarding the beam quality information from the network side device through the communication unit 120 .

[0079] According to an embodiment of the present disclosure, as shown in FIG1 , the user equipment 100 may further include a decoding unit 160 for decoding feedback information to determine whether the network-side device has received beam quality information.

[0080] According to an embodiment of the present disclosure, the user equipment 100 may use the PUCCH, such as the UCI (Uplink Control Information) in the PUCCH, to transmit beam quality information. In this case, the network-side device may use DCI format 0 (DCI format 0) or DCI format 2 (DCI format 2) to transmit feedback information, so that the decoding unit 160 decodes the feedback information to determine ACK and NACK. If the decoding unit 160 determines ACK, the user equipment 100 may determine that the network-side device has received the beam quality information; if the decoding unit 160 determines NACK, the user equipment 100 may determine that the network-side device has not received the beam quality information. The following describes in detail two scenarios in which the network-side device transmits feedback information using DCI format 0 and DCI format 2.

[0081] According to an embodiment of the present disclosure, the network-side device may use DCI format 0, such as DCI format 0_1, to send feedback information. Specifically, after the user equipment 100 obtains information in DCI format 0_1, it may determine whether the information is for PUSCH, PUCCH, or PUSCH and PUCCH feedback based on the DFI (Downlink Feedback Information) flag, and further determine ACK or NACK based on the HARQ-ACK bitmap of the PUCCH, or based on the HARQ-ACK bitmap of the PUSCH and PUCCH.

[0082] Figure 2 is an example diagram showing that a network-side device according to an embodiment of the present disclosure uses DCI format 0_1 ​​to send feedback information. As shown in Figure 2, DCI format 0_1 ​​includes a DCI format identifier, a carrier indication, a DFI flag, a HARQ-ACK bitmap, a TPC (Transmit Power Control) and a reserved bit. When the DFI flag is 01, the HARQ-ACK bitmap represents the HARQ-ACK bitmap for PUSCH, and TPC represents the TPC for PUSCH; when the DFI flag is 10, the HARQ-ACK bitmap represents the HARQ-ACK bitmap for PUCCH, and TPC represents the TPC for PUCCH; when the DFI flag is 11, the HARQ-ACK bitmap represents the HARQ-ACK bitmap for PUSCH and PUCCH, and TPC represents the TPC for PUSCH and PUCCH; when the DFI flag is 00, there is no HARQ-ACK bitmap, TPC and reserved bit information, indicating uplink scheduling grant information.

[0083] As described above, when the user equipment 100 uses PUCCH to send beam quality information and the network side device sends ACK or NACK, the network side device can reuse DCI format 0_1 ​​to carry feedback information, and only a small change to DCI format 0_1 ​​is required to achieve the carrying of feedback information.

[0084] According to an embodiment of the present disclosure, the network-side device may use DCI format 2, such as DCI format 2_x, to send feedback information. Specifically, after the user equipment 100 obtains the information in DCI format 2_x, the feedback information of the user equipment 100 may be determined from the HARQ-ACK codebook for all PUCCH resources based on the PUCCH resource in which the user equipment 100 transmits beam quality information, thereby determining ACK or NACK.

[0085] Figure 3 is an example diagram showing that a network side device sends feedback information using DCI format 2_x according to an embodiment of the present disclosure. As shown in Figure 3, DCI format 2_x includes PUCCH resources 1 to PUCCH resources N, and HARQ-ACK codebooks for PUCCH resources 1-N.

[0086] As described above, when user equipment 100 uses the PUCCH to transmit beam quality information and the network device sends an ACK or NACK, the network device can design a new DCI format 2_x to carry the feedback information. Furthermore, user equipment 100 can use the RNTI (Radio Network Temporary Identity) dedicated to DCI format 2_x to decode the DCI format.

[0087] According to an embodiment of the present disclosure, the user equipment 100 can use the PUCCH, such as the UCI (Uplink Control Information) in the PUCCH, to send beam quality information. In this case, the network device can use DCI format 1 (DCI format 1), such as DCI format 1_1 and DCI format 1_2, to send feedback information, so that the decoding unit 160 decodes the feedback information to determine a negative acknowledgement (NACK). If the decoding unit 160 determines a negative acknowledgement (NACK), the user equipment 100 can determine that the network device did not receive the beam quality information. If the user equipment 100 does not receive a negative acknowledgement (NACK), the user equipment 100 can determine that the network device did receive the beam quality information. In this way, the network device can only feedback a negative acknowledgement (NACK), thereby significantly reducing signaling overhead. The following describes in detail two scenarios in which the network device uses DCI format 1_1 and DCI format 1_2 to send feedback information.

[0088] According to an embodiment of the present disclosure, the network side device may use a specific value of one or more fields in DCI format 1_1 to represent NACK feedback information. For example, the network side device may use one or more specific values ​​of the RV (Redundancy Version) field, the MCS (Modulation and Coding Scheme) field, and the FDRA (Frequency Domain Resource Assignment) field to represent NACK. As a non-limiting example, when the user equipment 100 determines that the values ​​of the RV field are all 1, the values ​​of the MCS field are all 1, and the values ​​of the FDRA field are all 0 according to DCI format 1_1, the user equipment 100 may determine NACK, that is, the network side device has not received the beam quality information; otherwise, it is determined that the network side device has received the beam quality information.

[0089] Figure 4 is an example diagram showing a network device transmitting feedback information using DCI format 1_1 according to an embodiment of the present disclosure. As shown in Figure 4, DCI format 1_1 includes a DCI format identifier, a carrier indicator, an RV field, an MCS field, an FDRA field, and a PUCCH resource indicator. If the RV field values ​​are all 1, the MCS field values ​​are all 1, and the FDRA field values ​​are all 0, the user equipment 100 may determine that NACK information has been received.

[0090] According to an embodiment of the present disclosure, the network side device may use a specific value of one or more fields in DCI format 1_2 to represent NACK feedback information. For example, the network side device may use one or more specific values ​​of the RV (Redundancy Version) field, the MCS (Modulation and Coding Scheme) field, and the FDRA (Frequency Domain Resource Assignment) field to represent NACK. As a non-limiting example, when the user equipment 100 determines that the values ​​of the RV field are all 1, the values ​​of the MCS field are all 1, and the values ​​of the FDRA field are all 0 according to DCI format 1_2, the user equipment 100 may determine NACK, that is, the network side device has not received the beam quality information; otherwise, it is determined that the network side device has received the beam quality information.

[0091] Figure 5 is an example diagram showing a network device sending feedback information using DCI format 1_2 according to an embodiment of the present disclosure. As shown in Figure 5, DCI format 1_2 includes a DCI format identifier, a carrier indicator, an RV field, an MCS field, an FDRA field, and a PUCCH resource indicator. If the values ​​of the RV field are all 1, the values ​​of the MCS field are all 1, and the values ​​of the FDRA field are all 0, the user equipment 100 may determine that NACK information has been received.

[0092] It is worth noting that although the above describes an embodiment in which NACK information is indicated by all RV field values ​​being 1, all MCS field values ​​being 1, and all FDRA field values ​​being 0, this embodiment is not restrictive. The network-side device may use other combinations of fields, as well as other specific field values, to indicate NACK.

[0093] As described above, according to an embodiment of the present disclosure, when the user equipment 100 uses PUCCH to transmit beam quality information and the network side device only feeds back NACK instead of ACK, the network side device can use DCI format 1 to carry feedback information.

[0094] According to an embodiment of the present disclosure, user equipment 100 may transmit beam quality information using a PUSCH, such as UCI or MAC CE in the PUSCH. In this case, the network-side device may transmit feedback information using DCI format 0, such as DCI format 0_0 and DCI format 0_1, so that decoding unit 160 decodes the feedback information to determine the feedback information.

[0095] Specifically, the network side device can use the content of the NDI (New Data indicator) field in the uplink scheduling grant in DCI format 0_0 or DCI format 0_1 ​​to indicate ACK or NACK. After the user equipment 100 receives DCI format 0_0 or DCI format 0_1, it can determine whether the network side device has received the beam quality information based on the value of the NDI field. For example, when the value of the NDI field is 1, it indicates an ACK message, that is, the network side device has received the beam quality information; when the value of the NDI field is 0, it indicates a NACK message, that is, the network side device has not received the beam quality information. Further, the user equipment 100 can determine the NDI corresponding to the sent beam quality information based on the identification information (HARQ process ID) of the HARQ process.

[0096] As described above, according to an embodiment of the present disclosure, when the user equipment 100 uses PUSCH to transmit beam quality information, the network side device can carry feedback information through the identification information of the HARQ process and the NDI field in DCI format 0.

[0097] According to an embodiment of the present disclosure, when the user equipment 100 determines that the network-side device has not received the beam quality information, the user equipment 100 may retransmit the beam quality information.

[0098] As described above, the present disclosure considers that the network side device needs to provide feedback on the beam quality information sent by the user equipment 100. Furthermore, the present disclosure designs details of how the network side device sends feedback information, thereby improving the reliability of the beam quality information.

[0099] According to an embodiment of the present disclosure, the user equipment 100 may also receive uplink scheduling information from a network-side device via the communication unit 120. For example, the user equipment 100 may receive uplink scheduling information according to DCI format 0.

[0100] According to an embodiment of the present disclosure, the uplink scheduling information may include multiple SRIs (SRS Resource Indicators). As shown in FIG1 , the user equipment 100 may further include a panel determining unit 170 configured to determine multiple panels for uplink transmission according to the multiple SRIs in the uplink scheduling information.

[0101] According to an embodiment of the present disclosure, an SRI can be used to indicate an SRS resource in an SRS resource set. Since an SRS resource has a one-to-one correspondence with an uplink beam, an SRS resource can be used to indicate a specific beam of the user equipment 100, that is, a specific panel of the user equipment 100. In other words, the panel determination unit 170 can determine a panel based on each SRI, and thus can determine multiple panels based on multiple SRIs.

[0102] According to an embodiment of the present disclosure, the uplink scheduling information may also include an SRI, and the panel determining unit 170 is configured to determine a plurality of panels for uplink transmission according to an SRI in the uplink scheduling information.

[0103] According to the embodiments of the present disclosure, a mapping relationship between beam combinations and SRIs can be preset between the user equipment 100 and the network-side device. In other words, various beam combinations on different panels can be listed, with each combination having a mapping relationship with an SRI. In this way, the user equipment 100 can determine the beam combination based on an SRI in the uplink scheduling information, that is, determine multiple SRS resources in multiple SRS resource sets, thereby determining multiple beams, and then determining the panels where the multiple beams are located.

[0104] It can be seen that the user equipment 100 can determine multiple beams on multiple panels scheduled by the network side device based on the uplink scheduling information from the network side device.

[0105] According to an embodiment of the present disclosure, the uplink scheduling information may further include a TPMI (Transmission Precoder Matrix Index). As shown in FIG1 , the user equipment 100 may further include a precoding matrix determination unit 180 configured to determine precoding matrices for multiple panels scheduled by the network-side device based on the TPMI in the uplink scheduling information.

[0106] According to an embodiment of the present disclosure, when the uplink scheduling information includes a TPMI, it indicates that the multiple panels scheduled by the network-side device are coherent, and therefore these multiple panels can use the same precoding matrix. Therefore, the precoding matrix determination unit 180 can use the precoding matrix indicated by the TPMI as the precoding matrix for the multiple panels.

[0107] According to an embodiment of the present disclosure, when the uplink scheduling information includes multiple TPMIs, it indicates that the multiple panels scheduled by the network side device are in an incoherent relationship, and therefore the multiple panels use different precoding matrices. Furthermore, the precoding matrix determination unit 180 can also determine the number of precoding matrices for each panel, that is, the number of TPMIs, based on the intra-panel coherence type of each scheduled panel. That is, when the intra-panel coherence type is fully coherent, all ports of the panel use the same precoding matrix, that is, the number of TPMIs is 1; when the intra-panel coherence type is incoherent, all ports of the panel use different precoding matrices, that is, the number of TPMIs is the same as the number of ports; when the intra-panel coherence type is partially coherent, the coherent ports of the panel use the same precoding matrix, and the incoherent ports use different precoding matrices.

[0108] For example, if the network-side device schedules panels A and B, and panels A and B are coherent, the user equipment 100 can determine a precoding matrix based on one TPMI, and all ports of panel A and all ports of panel B use this precoding matrix. For another example, if the network-side device schedules panels C and D, and panels C and D are incoherent, the intra-panel coherence relationship of panel C is fully coherent, the intra-panel coherence relationship of panel D is incoherent, and panel D has two ports, the user equipment can determine three precoding matrices based on three TPMIs, where all ports of panel C use precoding matrix 1, and the two ports of panel D use precoding matrix 2 and precoding matrix 3, respectively. For another example, the network side device schedules panel E and panel F, panel E and panel F are incoherent, the intra-panel coherence relationship of panel E is completely coherent, the intra-panel coherence relationship of panel F is partially coherent, and panel F has 4 ports, among which ports a and b are coherent. Then the user equipment can determine 4 precoding matrices according to the 4 TPMIs, among which all ports of panel E use precoding matrix 1, ports a and b of panel F use precoding matrix 2, port c uses precoding matrix 3, and port d uses precoding matrix 4.

[0109] Here, the network side device can, for example, determine the coherence relationship between each panel through the inter-panel coherence type in the beam quality information, and determine the coherence relationship between the ports of each panel through the intra-panel coherence type class in the panel information, thereby determining the number of precoding matrices required for each panel.

[0110] As described above, according to the embodiments of the present disclosure, the user equipment 100 can determine the precoding matrix used by each port of the multiple scheduled antenna panels through the uplink scheduling information of the network-side device.

[0111] As described above, the present disclosure designs details of the network side device simultaneously scheduling multiple panels of the user equipment 100, so that the network side device can use uplink scheduling information to simultaneously schedule multiple panels and configure precoding matrices for the multiple panels.

[0112] It can be seen that according to the embodiments of the present disclosure, regardless of whether the user capability value sets are the same, the user device 100 can report the panel to the network side device, that is, the network side has no restrictions when scheduling multiple panels. In addition, the present disclosure defines two user capability values ​​in the user capability value set: the number of SRS ports and the coherence type within the panel. Further, the present disclosure believes that the network side device needs to feedback the beam quality information sent by the user device 100, and designs the details of the feedback information sent by the network side device, so as to improve the reliability of the beam quality information. In addition, the present disclosure designs the details of the network side device simultaneously scheduling multiple panels of the user device 100, so that the network side device can use the uplink scheduling information to schedule multiple panels at the same time, and configure precoding matrices for multiple panels. In summary, the present disclosure optimizes the multi-panel uplink transmission process of the user device 100.

[0113] <3. Example of Network-Side Device Configuration>

[0114] 6 is a block diagram showing the structure of an electronic device 600 used as a network-side device in a wireless communication system according to an embodiment of the present disclosure. The electronic device 600 here may be, for example, a base station device.

[0115] As shown in FIG. 6 , the electronic device 600 may include a communication unit 610 and a determination unit 620 .

[0116] Here, each unit of electronic device 600 may be included in a processing circuit. It should be noted that electronic device 600 may include either one processing circuit or multiple processing circuits. Furthermore, 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.

[0117] According to an embodiment of the present disclosure, the electronic device 600 may receive panel information from a user device through the communication unit 610. The user device here may be a user device within the service range of the electronic device 600.

[0118] According to an embodiment of the present disclosure, the determining unit 620 may determine a user capability value set for each of multiple panels of the user device according to panel information, wherein user capability values ​​in user capability value sets of different panels may be the same or different.

[0119] As described above, according to the embodiments of the present disclosure, the user capability values ​​in the user capability value sets of different panels in the panel information may be the same or different. In other words, the present disclosure removes the restriction that a user device cannot report two panels with the same user capability value, i.e., removes the restriction on multi-panel uplink transmission, thereby enabling the user device to report to any panel, and thus allowing the electronic device 600 to schedule any panel, thereby optimizing the multi-panel uplink transmission process of the user device.

[0120] According to an embodiment of the present disclosure, the determination unit 620 can determine one or more user capability values ​​included in the user capability value set based on the user capability value set. Here, the user capability value may include an intra-panel coherence type, which indicates the coherence between multiple ports of the panel. The coherence between multiple ports of the panel includes full coherence, partial coherence, and incoherence. In other words, the determination unit 620 can determine the intra-panel coherence type of each panel based on the panel information from the user device, namely, full coherence, partial coherence, and incoherence.

[0121] According to an embodiment of the present disclosure, when multiple ports of a panel are partially coherent, the coherence between multiple ports of the panel also includes partially coherent ports. That is, when the coherence type within the panel is partially coherent, the determination unit 620 can also determine the coherent ports.

[0122] According to an embodiment of the present disclosure, the user capability value may also include the number of SRS ports. Specifically, the determination unit 620 may determine the number of SRS ports for each panel based on panel information from the user device. In other words, the user capability value set for each panel may include two user capability values: the number of SRS ports and the intra-panel coherence type.

[0123] According to an embodiment of the present disclosure, the electronic device 600 may perform RRC configuration on the user equipment and send RRC configuration information to the user equipment. In addition, the electronic device 600 may also send a reference signal to the user equipment for the user equipment to measure the channel quality of each beam of each panel.

[0124] According to an embodiment of the present disclosure, the electronic device 600 may further receive beam quality information for each panel from the user equipment through the communication unit 610 .

[0125] According to an embodiment of the present disclosure, the determination unit 620 may determine the preferred beam of the panel according to the beam quality information.

[0126] According to an embodiment of the present disclosure, the beam quality information of each panel may include panel indication information and beam indication information, and the determination unit 620 may determine the preferred beam of each panel based on the panel indication information and beam indication information in the beam quality information. Furthermore, since there is a one-to-one correspondence between the panel and the user capability value set, the panel indication information may be represented by the identification information of the user capability value set (UE capability value set ID), so that the determination unit 620 may determine the panel based on the identification information of the user capability value set. In addition, since there is a one-to-one correspondence between the downlink reference signal of the network-side device and the beam, the beam indication information may be represented by CRI or SSBRI, so that the determination unit may determine the beam based on CRI or SSBRI.

[0127] According to an embodiment of the present disclosure, the determining unit 620 may further determine the channel quality information of the preferred beam of the panel, such as L1-SINR or L1-RSRP, based on the beam quality information.

[0128] According to an embodiment of the present disclosure, the determination unit 620 can determine the inter-panel coherence type of the panel based on the beam quality information. The inter-panel coherence type indicates the coherence situation between the panel and other panels. The coherence situation between the panel and other panels includes incoherence and coherence. Further, in the case where the panel is coherent with other panels, the coherence situation between the panel and other panels also includes information of other panels that are coherent with the panel. That is, the determination unit 620 can determine whether there are other panels that are coherent with the panel based on the inter-panel coherence type, and in the case where there are other panels that are coherent with the panel, the determination unit 620 can also determine the other panels that are coherent with the panel. For example, the determination unit 620 can determine the other panels based on the identification information of the user capability value set.

[0129] According to an embodiment of the present disclosure, as shown in Figure 6 , the electronic device 600 may further include a generating unit 630 configured to generate feedback information for beam quality information. Furthermore, the electronic device 600 may send the feedback information to the user equipment via the communication unit 610 .

[0130] According to an embodiment of the present disclosure, when a user equipment transmits beam quality information via the PUCCH, the electronic device 600 may use DCI format 0 or DCI format 2 to carry feedback information, which includes ACK and NACK. That is, if the electronic device 600 successfully receives the beam quality information, the generation unit 630 generates an ACK; if the electronic device 600 fails to successfully receive the beam quality information, the generation unit 630 generates a NACK.

[0131] According to an embodiment of the present disclosure, the electronic device 600 may use DCI format 0, such as DCI format 0_1, to send feedback information. Specifically, the electronic device 600 may use the DFI flag to indicate whether the information is for PUSCH, PUCCH, or PUSCH and PUCCH feedback, and generate a HARQ-ACK bitmap for PUCCH or a HARQ-ACK bitmap for PUSCH and PUCCH based on the feedback information. Specifically, as shown in FIG2 , DCI format 0_1 ​​includes a DCI format identifier, a carrier indication, a DFI flag, a HARQ-ACK bitmap, a TPC, and a reserved bit. When the DFI flag is 01, the HARQ-ACK bit map represents the HARQ-ACK bit map for PUSCH, and TPC represents the TPC for PUSCH; when the DFI flag is 10, the HARQ-ACK bit map represents the HARQ-ACK bit map for PUCCH, and TPC represents the TPC for PUCCH; when the DFI flag is 11, the HARQ-ACK bit map represents the HARQ-ACK bit map for PUSCH and PUCCH, and TPC represents the TPC for PUSCH and PUCCH; when the DFI flag is 00, there is no HARQ-ACK bit map, TPC, and reserved bit information, indicating uplink scheduling grant information.

[0132] As described above, when the user equipment uses PUCCH to send beam quality information and the electronic device 600 sends ACK or NACK, the electronic device 600 can reuse DCI format 0_1 ​​to carry feedback information, and only a small change to DCI format 0_1 ​​is required to achieve the carrying of feedback information.

[0133] According to an embodiment of the present disclosure, the electronic device 600 may use DCI format 2, such as DCI format 2_x, to send feedback information. Specifically, the generation unit may determine the HARQ-ACK codebook for all PUCCH resources based on the feedback information and the resources of the PUCCH for the user equipment to transmit beam quality information. That is, the HARQ-ACK codebook for all PUCCH resources may include feedback information of multiple user equipments served by the electronic device 600. Specifically, as shown in FIG3 , DCI format 2_x includes PUCCH resources 1 to PUCCH resource N, and HARQ-ACK codebooks for PUCCH resources 1-N.

[0134] As described above, when the user equipment transmits beam quality information using the PUCCH and the electronic device 600 transmits an ACK or NACK, the electronic device 600 may design a new DCI format 2_x to carry the feedback information. Furthermore, the electronic device 600 may allocate a new RNTI (Radio Network Temporary Identity) to scramble the newly designed DCI format 2_x.

[0135] According to an embodiment of the present disclosure, when a user equipment transmits beam quality information via the PUCCH, the electronic device 600 may use DCI format 1 to carry feedback information, where the feedback information includes a negative acknowledgement (NACK). That is, if the electronic device 600 successfully receives the beam quality information, no feedback information is transmitted; if the electronic device 600 fails to successfully receive the beam quality information, the generation unit 630 generates a negative acknowledgement (NACK).

[0136] According to an embodiment of the present disclosure, the electronic device 600 may utilize a specific value of one or more fields in DCI format 1_1 or DCI format 1_2 to represent NACK feedback information. For example, the electronic device 600 may utilize a specific value of one or more of the RV field, the MCS field, and the FDRA field to represent NACK. As a non-limiting example, the values ​​of the RV field are all 1, the values ​​of the MCS field are all 1, and the values ​​of the FDRA field are all 0 to represent NACK. Specifically, as shown in Figures 4 and 5, DCI format 1_1 and DCI format 1_2 include a DCI format identifier, a carrier indication, an RV field, an MCS field, an FDRA field, and a PUCCH resource indication. When the values ​​of the RV field are all 1, the values ​​of the MCS field are all 1, and the values ​​of the FDRA field are all 0, NACK information is represented. In addition, the electronic device 600 may also utilize the PUCCH resource indication field to indicate a PUCCH that was not successfully decoded.

[0137] As described above, according to an embodiment of the present disclosure, when the user equipment transmits beam quality information using PUCCH and the electronic device 600 only feeds back NACK instead of ACK, the electronic device 600 can reuse DCI format 1 to carry feedback information.

[0138] According to an embodiment of the present disclosure, when a user equipment transmits beam quality information via a PUSCH, the electronic device 600 may use the content of the NDI field in DCI format 0 to indicate feedback information. For example, the electronic device 600 may use the content of the NDI field in the uplink scheduling grant in DCI format 0_0 or DCI format 0_1 ​​to indicate ACK or NACK. When the electronic device 600 successfully receives the beam quality information, the value of the NDI field may be set to 1; when the electronic device 600 does not successfully receive the beam quality information, the value of the NDI field may be set to 0. Furthermore, the electronic device 600 may determine the NDI corresponding to the transmitted beam quality information based on the identification information (HARQ process ID) of the HARQ process.

[0139] As described above, according to an embodiment of the present disclosure, when the user equipment uses PUSCH to transmit beam quality information, the electronic device 600 can carry feedback information through the identification information of the HARQ process and the NDI field in DCI format 0.

[0140] As described above, the present disclosure considers that the electronic device 600 needs to provide feedback on the beam quality information sent by the user equipment. Furthermore, the present disclosure designs details of how the electronic device 600 sends feedback information, thereby improving the reliability of the beam quality information.

[0141] According to an embodiment of the present disclosure, as shown in Figure 6, electronic device 600 may further include a panel determination unit 640 for determining a plurality of panels for uplink transmission for a user equipment. Furthermore, generation unit 630 may generate uplink scheduling information, and electronic device 600 may transmit the uplink scheduling information to the user equipment via communication unit 610. Here, electronic device 600 may transmit the uplink scheduling information using DCI format 0.

[0142] According to an embodiment of the present disclosure, uplink scheduling information may include multiple SRIs to indicate multiple panels scheduled for the user equipment. That is, the electronic device 600 may determine multiple beams on multiple panels that need to be scheduled. Since SRIs have a one-to-one correspondence with uplink beams, multiple SRIs may be used to indicate multiple beams, thereby indicating multiple panels.

[0143] According to an embodiment of the present disclosure, uplink scheduling information may include an SRI to indicate multiple beams on multiple panels scheduled for a user equipment. For example, a mapping relationship between beam combinations and SRIs may be preset between the user equipment and the electronic device 600. In other words, various combinations of beams on different panels may be listed, with each combination having a mapping relationship with an SRI. In this way, the electronic device 600 can determine the SRI corresponding to the scheduled beam combination and include the SRI in the uplink scheduling information.

[0144] According to an embodiment of the present disclosure, as shown in FIG6 , the electronic device 600 may further include a precoding matrix determining unit 650 , configured to determine a precoding matrix for each port of the plurality of scheduled panels.

[0145] According to an embodiment of the present disclosure, when multiple panels scheduled by the electronic device 600 are coherent, these multiple panels can use the same precoding matrix. Therefore, the precoding matrix determination unit 650 can determine a precoding matrix to be used as the precoding matrix for multiple panels, and the generation unit 630 can indicate the precoding matrix with a TPMI and include the TPMI in the uplink scheduling information.

[0146] According to an embodiment of the present disclosure, when multiple panels scheduled by electronic device 600 are incoherent, the multiple panels use different precoding matrices. The precoding matrix determination unit 650 can also determine the number of precoding matrices for each panel based on the intra-panel coherence type of each scheduled panel. Specifically, when the intra-panel coherence type is fully coherent, all ports on the panel use the same precoding matrix, i.e., the number of precoding matrices required for the panel is one. When the intra-panel coherence type is incoherent, all ports on the panel use different precoding matrices, i.e., the number of precoding matrices required for the panel is the same as the number of ports. When the intra-panel coherence type is partially coherent, the coherent ports of the panel use the same precoding matrix, while the incoherent ports use different precoding matrices. Furthermore, after the precoding matrix determination unit 650 determines the number of precoding matrices for each panel, the generation unit 630 can indicate the multiple precoding matrices using a corresponding number of TPMIs and include these multiple TPMIs in the uplink scheduling information.

[0147] Here, the electronic device 600 can determine the coherence relationship between each panel through the inter-panel coherence type in the beam quality information, and determine the coherence relationship between the ports of each panel through the intra-panel coherence type class in the panel information, thereby determining the number of TPMIs that need to be sent.

[0148] As described above, the present disclosure designs details of the electronic device 600 scheduling multiple panels of the user equipment simultaneously, so that the electronic device 600 can use uplink scheduling information to schedule multiple panels simultaneously and configure precoding matrices for the multiple panels.

[0149] It can be seen that according to the embodiments of the present disclosure, regardless of whether the user capability value sets are the same, the user equipment can report the panel to the electronic device 600, that is, the electronic device 600 has no restrictions when scheduling multiple panels. In addition, the present disclosure defines two user capability values ​​in the user capability value set: the number of SRS ports and the coherence type within the panel. Further, the present disclosure believes that the electronic device 600 needs to provide feedback on the beam quality information sent by the user equipment, and designs the details of the electronic device 600 sending feedback information, thereby improving the reliability of the beam quality information. In addition, the present disclosure designs the details of the electronic device 600 simultaneously scheduling multiple panels of the user equipment, so that the electronic device 600 can use the uplink scheduling information to schedule multiple panels at the same time, and configure precoding matrices for multiple panels. In summary, the present disclosure optimizes the multi-panel uplink transmission process of the user equipment.

[0150] <4. Method Example>

[0151] Figure 7 is a signaling flow chart illustrating the process of scheduling multiple panels for a user equipment (UE) according to an embodiment of the present disclosure. In Figure 7 , the UE may be implemented by user equipment 100, and the gNB may be implemented by electronic device 600. As shown in Figure 7 , in step S701, the UE generates panel information, including a set of user capability values ​​for each panel. In step S702, the UE sends the panel information to the gNB. In step S703, the gNB performs RRC configuration on the UE. In step S704, the gNB performs downlink beam scanning on the UE. In step S705, the UE measures the channel quality of each beam and generates beam quality information. In step S706, the UE sends the generated beam quality information to the gNB. In step S707, the gNB generates feedback information. In step S708, the gNB sends the feedback information to the UE. In step S709, the gNB determines the multiple panels scheduled for the UE and the precoding matrix for each port of each panel, and generates uplink scheduling information. In step S710, the gNB sends uplink scheduling information to the UE. In step S711, the UE performs uplink transmission using the panel scheduled by the gNB. This enables the gNB to schedule multiple panels for the UE's uplink transmission.
