[0044] The following describes the scenarios of the embodiments of the present application through examples, but the present application is not limited thereto.

[0045] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0046] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include but are not limited to: enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0047] It is worth noting that FIG1 shows that both terminal devices 102 and 103 are within the coverage range of network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 may not be within the coverage range of network device 101, or one terminal device 102 may be within the coverage range of network device 101 while the other terminal device 103 is outside the coverage range of network device 101.

[0048] Currently, a partially coherent terminal device with two antenna groups (Ng=2) can report capability information, which indicates which antenna group can support a single bit at full power.

[0049] For a partially coherent terminal device with four antenna groups (Ng=4), a quaternary group can be defined for capability reporting. Table 1 schematically shows an example of capability reporting for a partially coherent terminal device with four antenna groups (Ng=4), which supports full power mode 2.

[0050] Table 1

[0051] For example, if x is a non-zero value, the above quaternion (x, 0, 0, 0) indicates that antenna group #1 operates at full power, while antenna groups #2, #3, and #4 do not. Therefore, for example, 14 bits are required to report capability information, resulting in high overhead. Furthermore, the relationship between groups is not clearly defined, which affects the flexibility and reliability of terminal device capability reporting. Therefore, for terminal devices supporting full power mode 2, capability reporting needs to be enhanced.

[0052] In the embodiments of the present application, the high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, an RRC message, including, for example, an MIB, system information, or a dedicated RRC message; or an RRC information element (RRC IE). The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or a MAC control element (MAC CE). However, the present application is not limited thereto.

[0053] In the following description, to avoid confusion, the terms "PDCCH" and "Physical Downlink Control Channel" or "downlink control information" are interchangeable, and the terms "PDSCH" and "Physical Downlink Data Channel" or "downlink data" are also interchangeable. Furthermore, transmitting or receiving a PDCCH can be understood as transmitting or receiving downlink control information carried by the PDCCH; transmitting or receiving a PDSCH can be understood as transmitting or receiving downlink data carried by the PDSCH.

[0054] Embodiments of the first aspect

[0055] An embodiment of the present application provides a capability reporting method, which is described from the perspective of a terminal device that can support 8-transmission (8Tx) uplink transmission, and the terminal device supports full power mode 2.

[0056] FIG2 is a schematic diagram of a capability reporting method according to an embodiment of the present application. As shown in FIG2 , the method includes:

[0057] 201. The terminal device sends full power capability reporting information to the network device.

[0058] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0059] In some embodiments, the terminal device is a partially coherent terminal device with 4 antenna groups (Ng=4).

[0060] For example, for a partially coherent UE with four antenna groups (Ng=4) and supporting full power mode 2, which antenna group and / or antenna groups are capable of full power operation may be reported to the network device.

[0061] In some embodiments, the full power capability reporting information includes indication information for indicating antenna groups capable of full power operation.

[0062] In some embodiments, the indication information includes one or more bits, each bit indicating a quadruple, and the quadruple indicates that one or more antenna groups among the four antenna groups are required to perform full power operation.

[0063] For example, a quadruple (A, B, C, D) can be defined, with A, B, C, and D corresponding to antenna groups #1, #2, #3, and #4, respectively. The values ​​of A, B, C, and D can be 0 or non-zero (e.g., x). Full power operation can be achieved by the antenna group corresponding to a non-zero value (e.g., x). For example, (x, 0, x, 0) means that full power can be achieved by two antenna groups (antenna group #1 and antenna group #3).

[0064] In some embodiments, the quads are divided into one or more sets, where one set corresponds to one or more quads.

[0065] For example, it may include a first set, a second set, and a third set, wherein the first set corresponds to a four-tuple requiring one antenna group for full-power operation, the second set corresponds to a four-tuple requiring two antenna groups for full-power operation, and the third set corresponds to a four-tuple requiring three antenna groups for full-power operation.

[0066] Table 2 schematically shows an example of capability reporting of a partially coherent terminal device with four antenna groups (Ng=4), which supports full power mode 2.

[0067] Table 2

[0068] As shown in Table 2, the quads can be divided into several categories (also referred to as sets). In category #1, full power transmission can be achieved with one antenna group. In category #2, two antenna groups are required to provide full power (or at least two antenna groups are required to provide full power). In category #3, three antenna groups are required to provide full power (or at least three antenna groups are required to provide full power).

[0069] For example, the UE may report to the network device that it supports only one category, or supports multiple categories (such as any combination of the above categories) by reporting full power capability information.

[0070] In some embodiments, a terminal device that supports the first set may also (or is able to, is allowed to) support (this support is optional) the second set and / or the third set; a terminal device that supports the second set may also (or is able to, is allowed to) support (this support is optional) the third set.

[0071] Table 3 schematically shows another example of capability reporting of a partially coherent terminal device with four antenna groups (Ng=4), which supports full power mode 2.

[0072] Table 3

[0073] Table 4 schematically shows another example of capability reporting of a partially coherent terminal device with four antenna groups (Ng=4), which supports full power mode 2.

[0074] Table 4

[0075] In some embodiments, the one or more sets are explicitly indicated, or the one or more sets are implicitly supported.

[0076] For example, one or more categories may be explicitly indicated as shown in Tables 2 to 4.

[0077] As another example, the group classification is implicit, that is, the categories are not explicitly defined. For example, Group 1 to Group 4 correspond to Category #1, Group 5 to Group 10 correspond to Category #2, and Group 11 to Group 14 correspond to Category #3. For the Groups in Table 2, a UE that supports Group 1 to Group 4 can also support Group 5 to Group 10 and / or Group 11 to Group 14. A UE that supports Group 5 to Group 10 can also support Group 11 to Group 14.

[0078] Table 5 schematically shows another example of capability reporting of a partially coherent terminal device with four antenna groups (Ng=4), which supports full power mode 2.

[0079] Table 5

[0080] In some embodiments, the set includes N quadruples, where N is greater than or equal to 1. For example, the value of N is different for different sets.

[0081] For example, a UE may support only one group or N groups (N ≥ 1) in each category. The category may be explicitly indicated as shown in Tables 2 to 4, or may be implicitly indicated as shown in Table 5. The value of N may be predefined. The value of N may be the same for different categories, or may be different for different categories.

[0082] In some embodiments, the terminal device is a fully coherent terminal device supporting full power mode 2, and the full power capability reporting information is the same as the capability reporting information of a partially coherent terminal device with 2 antenna groups (Ng=2).

[0083] For example, for a fully coherent UE supporting full power mode 2, the full power capability reporting may be the same as the full power capability reporting of a partially coherent UE with two antenna groups (Ng=2).

[0084] In some embodiments, the terminal device is a fully coherent terminal device supporting full power mode 2, and the full power capability reporting information is determined according to a codebook type supported by the terminal device.

[0085] In one example, if the terminal device supports the codebook of Ng=2, the full-power capability reporting information is the same as the capability reporting information of a partially coherent terminal device with 2 antenna groups (Ng=2); if the terminal device supports the codebook of Ng=4, the full-power capability reporting information is the same as the capability reporting information of a partially coherent terminal device with 4 antenna groups (Ng=4).

[0086] In another example, if the terminal device supports the codebooks of Ng=2 and Ng=4, the full power capability reporting information includes the full power capabilities of Ng=2 and Ng=4; if the terminal device supports neither the codebook of Ng=2 nor the codebook of Ng=4, the full power capability is not reported.

[0087] For example, the full power capability reporting depends on the codebook type supported by the UE. If the UE reports support for a codebook with Ng=2, the full power capability reporting can be the same as for a partially coherent UE with Ng=2. If the UE reports support for a codebook with Ng=4, the full power capability reporting can be the same as for a partially coherent UE with Ng=3.

[0088] For another example, if the UE reports support for codebooks Ng=2 and Ng=4, it should report full power capabilities for Ng=1 and Ng=4. If the fully coherent UE does not support codebooks Ng=2 or Ng=4, the UE does not report full power capabilities.

[0089] In some embodiments, the terminal device is a partially coherent terminal device with 2 antenna groups (Ng=2), and the full power capability of Ng=4 is also reported.

[0090] For example, for a partially coherent UE with Ng=2, the full power capability of Ng=4 should also be reported.

[0091] In some embodiments, if the terminal device reports a codebook supporting Ng=4, the full power capability of Ng=4 is also reported; or, if the terminal device does not report a codebook supporting Ng=4, the full power capability of Ng=4 is not reported either.

[0092] For example, if the UE reports that it supports the codebook of Ng=4, it should also report the full power capability of Ng=4; otherwise, the full power capability of Ng=4 is not reported.

[0093] In some embodiments, for full power mode 2, different port numbers of SRS resources are configured, including 1 port, 2 ports, 4 ports, or 8 ports. Alternatively, for full power mode 2, the port numbers of SRS resources must be the same.

[0094] For example, for terminal device capability reporting, one of the following or any combination of SRS ports can be reported: {(1-port, 2-ports), (1-port, 4-ports), (1-port, 8-ports), (2-ports, 4-ports), (2-ports, 8-ports), (4-ports, 8-ports), (1-port, 2-ports, 4-ports), (1-port, 2-ports, 8-ports), (1-port, 4-ports, 8-ports), (2-ports, 4-ports, 8-ports), (1-port, 2-ports, 4-ports, 8-ports)}.

[0095] In some embodiments, if the terminal device reports configurations supporting different SRS ports, the full power capability of 4 ports or 2 ports is also reported.

[0096] For example, when a UE reports support for different SRS port configurations, it should also report the 4-port / 2-port full power capability. For example, the 4-port / 2-port full power capability reporting can be the same as the legacy capability reporting. For another example, the 4-port / 2-port full power capability reporting can also be different from the legacy capability reporting.

[0097] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0098] It can be seen from the above embodiments that the embodiments of the present application enhance the capability reporting of terminal devices that support full power mode 2, thereby increasing flexibility and reliability and reducing overhead.

[0099] Embodiments of the second aspect

[0100] The embodiment of the present application provides a capability reporting method, which is described from the perspective of a network device.
