The term "base station" may also include some or all of their functions, and each base station can provide communication coverage for a specific geographical area. The term "cell" may refer to a base station and / or the area covered thereby, which depends on the context in which the term is used. Furthermore, unless confusion would be caused, the terms cell and base station are interchangeable.

[0022] In embodiments of the present invention, the term "User Equipment" (UE, User Equipment) or "Terminal Equipment" (TE, Terminal Equipment) refers to, for example, a device that accesses a communication network through a network device and receives services from the network. User equipment may be fixed or mobile, and is also referred to as a Mobile Station (MS, Mobile Station), a terminal, a Subscriber Station (SS, Subscriber Station), an Access Terminal (AT, Access Terminal), a station, etc.

Unless otherwise specified, “equipment” may refer to network equipment or terminal equipment.

[0026] The following describes a scenario of an embodiment of the present invention through examples, but the present invention is not limited thereto.

[0027] Figure 1 shows a communication system in an embodiment of the present invention. An example is shown with terminal equipment and network equipment. As shown in Figure 1, the communication system 100 may include network equipment 101 and terminal equipment 102 and 103. For convenience, Figure 1 uses two terminal devices and one network device as examples, but embodiments of the present invention are not limited to these.

[0028] In embodiments of the present invention, conventional services (services / traffic) or future services may be transmitted between the network device 101 and terminal devices 102 and 103. For example, these services may include, but are not limited to, eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), URLLC (Ultra-Reliable and Low-Latency Communication), etc.

[0029] Although Figure 1 shows that both terminal devices 102 and 103 are within the coverage of network device 101, the present invention is not limited to this. Neither of the two terminal devices 102 and 103 are located within the coverage of network device 101, or one terminal device 102 may be within the coverage of network device 101 and the other terminal device 103 may be outside the coverage of network device 101.

[0030] Currently, a partially coherent terminal device with two antenna groups (Ng=2) can report capability information, which is a single bit indicating which antenna group can support full power.

[0031] For a partially coherent terminal device having four antenna groups (Ng=4), a quaternary set can be defined and a capability report can be performed. Table 1 shows one example of a capability report for a partially coherent terminal device having four antenna groups (Ng=4), which supports full power mode 2.

[0032] [Table 1] For example, x is a non-zero value, and the above quaternary (x,0,0,0) represents that antenna group #1 performs full-power operation, while antenna groups #2, #3, and #4 do not. This results in a relatively large overhead, as, for example, 14 bits are required to report capability information. Furthermore, the lack of clearly defined relationships between groups can affect the flexibility and reliability of terminal equipment capability reporting. Therefore, capability reporting needs to be enhanced for terminal equipment that supports full-power mode 2.

[0033] In embodiments of the present invention, the upper-layer signaling may be, for example, a radio resource control (RRC) signaling, referred to as an RRC message, and including, for example, a MIB, system information, a dedicated RRC message, or referred to as an RRC IE (RRC information element). The upper-layer signaling may further be, for example, a MAC (Medium Access Control) signaling, or referred to as a MAC CE (MAC control element). However, the present invention is not limited to these.

[0034] In the following explanation, unless it causes confusion, the term “PDCCH” is interchangeable with “physical downlink control channel” or “downlink control information,” and the term “PDSCH” is interchangeable with “physical downlink data channel” or “downlink data.” Furthermore, transmitting or receiving a PDCCH may be understood as transmitting or receiving downlink control information carried by the PDCCH, and transmitting or receiving a PDSCH may be understood as transmitting or receiving downlink data carried by the PDSCH.

[0035] <Example of the first side view> An embodiment of the present invention provides a capability reporting method, described from the perspective of a terminal device capable of supporting 8 transmitter (8Tx) uplink transmission, wherein the terminal device supports full power mode 2.

[0036] Figure 2 shows a method for reporting capabilities in an embodiment of the present invention. As shown in Figure 2, the method includes the following, namely, 201: The terminal device sends full power capability report information to the network device.

[0037] Figure 2 above is provided to illustrate an embodiment of the present invention, but the present invention is not limited thereto. For example, the execution order between each operation can be appropriately adjusted, or several other operations can be added or removed. Those skilled in the art can make appropriate modifications based on the above description, without being limited to the description in Figure 2.

[0038] In some embodiments, the terminal device is a partially coherent terminal device having 4 antenna groups (Ng=4).

[0039] For example, a partially coherent UE having four antenna groups (Ng=4) and supporting full power mode 2 can report to network equipment one and / or more antenna groups capable of achieving full power operation.

[0040] In some embodiments, the full-power capability reporting information includes instructional information for indicating antenna groups capable of performing full-power operation.

[0041] In some embodiments, the instruction information includes one or more bits, each bit indicating a quaternion, which indicates that one or more of the four antenna groups need to be operated at full power.

[0042] For example, a quaternion can be defined as (A, B, C, D), where A, B, C, and D correspond to antenna groups #1, #2, #3, and #4, respectively. The values ​​of A, B, C, and D may be 0 (zero) or non-zero (e.g., x). Full power operation can be achieved by the antenna groups corresponding to the non-zero values ​​(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).

[0043] In some embodiments, the quaternary set is divided into one or more sets (collections), one of which corresponds to one or more quaternary sets.

[0044] For example, the set may include a first set, a second set, and a third set, where the first set corresponds to a quaternion requiring one antenna group to perform full-power operation, the second set corresponds to a quaternion requiring two antenna groups to perform full-power operation, and the third set corresponds to a quaternion requiring three antenna groups to perform full-power operation.

[0045] Table 2 shows one example of a capability report for a partially coherent terminal device having four antenna groups (Ng=4), which supports full power mode 2.

[0046] [Table 2] As shown in Table 2, quaternions can be divided into several categories (or sets). In Category #1, full power transmission can be achieved using 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).

[0047] For example, the UE may report to a network device through full-power capability reporting information that it supports only one category, or multiple categories (e.g., any combination of the categories mentioned above).

[0048] In some embodiments, a terminal device supporting the first set may (can, or is permitted to) support the second set and / or the third set (such support is optional), and a terminal device supporting the second set may (can, or is permitted to) support the third set (such support is optional).

[0049] Table 3 shows another example of a capability report for a partially coherent terminal device having four antenna groups (Ng=4), which supports full power mode 2.

[0050] [Table 3] Table 4 shows another example of capability reporting for a partially coherent terminal device having four antenna groups (Ng=4), which supports full power mode 2.

[0051] [Table 4] In some embodiments, the one or more sets are explicitly indicated, or the one or more sets are implicitly supported.

[0052] For example, one or more categories may be explicitly indicated, as shown in Tables 2 to 4.

[0053] Furthermore, for example, the group classification is implicit, meaning the categories are not clearly defined. For instance, Groups 1 through 4 correspond to Category #1, Groups 5 through 10 correspond to Category #2, and Groups 11 through 14 correspond to Category #3. For the Groups in Table 2, UEs supporting Groups 1 through 4 may also refer to Groups 5 through 10 and / or Groups 11 through 14. UEs for Groups 5 through 10 may also refer to Groups 11 through 14.

[0054] Table 5 shows another example of a capability report for a partially coherent terminal device having four antenna groups (Ng=4), which supports full power mode 2.

[0055] [Table 5] In some embodiments, the set contains N quaternions, where N is 1 or greater. For example, the value of N differs for different sets.

[0056] For example, UE may support only one group or N groups (N≧1) within each category, and the categories may be explicitly indicated as shown in Tables 2 to 4, or 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 the value of N may be different for different categories.

[0057] In some embodiments, the terminal device is a fully coherent terminal device that supports full power mode 2, and the full power capability report information is the same as the capability report information for a partially coherent terminal device having two antenna groups (Ng=2).

[0058] For example, for a fully coherent UE that supports full power mode 2, the full power capability report may be the same as the full power capability report for a partially coherent UE with two antenna groups (Ng=2).

[0059] In some embodiments, the terminal device is a fully coherent terminal device that supports full power mode 2, and the full power capability reporting information is determined based on the codebook type supported by the terminal device.

[0060] In one example, if the terminal device supports a codebook with Ng=2, the full-power capability report information is the same as the capability report information for a partially coherent terminal device having 2 antenna groups (Ng=2); if the terminal device supports a codebook with Ng=4, the full-power capability report information is the same as the capability report information for a partially coherent terminal device having 4 antenna groups (Ng=4).

[0061] In another example, if the terminal device supports codebooks for Ng=2 and Ng=4, the full power capability reporting information includes full power capabilities for Ng=2 and Ng=4. If the terminal device does not support codebooks for Ng=2 and does not support codebooks for Ng=4, then full power capability is not reported.

[0062] For example, full power capability reporting depends on the codebook types supported by the UE. If the UE reports supporting codebooks with Ng=2, then the full power capability reporting may be the same as that of a partially coherent UE with Ng=2. If the UE reports supporting codebooks with Ng=4, then the full power capability reporting may be the same as that of a partially coherent UE with Ng=4.

[0063] Furthermore, for example, if a UE reports that it supports codebooks with Ng=2 and Ng=4, it should report full power capability for both Ng=2 and Ng=4. If a fully coherent UE does not support codebooks with Ng=2 or Ng=4, the UE will not report full power capability.

[0064] In some embodiments, the terminal device is a partially coherent terminal device having two antenna groups (Ng=2), in which case full power capability with Ng=4 is also reported.

[0065] For example, for a partially coherent UE with Ng=2, the full-power capability of Ng=4 should also be reported.

[0066] In some embodiments, the terminal device is reported to support a codebook with Ng=4, and in this case, the full power capability of Ng=4 is also reported, or the terminal device is not reported to support a codebook with Ng=4, and in this case, the full power capability of Ng=4 is also not reported.

[0067] For example, if UE reports that it supports a codebook with Ng=4, it should also report the full power capability of Ng=4; otherwise, it should not report the full power capability of Ng=4.

[0068] In some embodiments, for full power mode 2, different numbers of SRS resource ports are configured, including 1 port, 2 ports, 4 ports, or 8 ports. Alternatively, for full power mode 2, the number of SRS resource ports is always the same.

[0069] For example, in terminal equipment capability reporting, one or any combination of SRS ports such as {(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)} may be reported.

[0070] In several embodiments, it has been reported that the terminal equipment supports different RS port configurations, and in these cases, full power capabilities for 4 ports or 2 ports are also reported.

[0071] For example, when a UE reports that it supports different SRS port configurations, it should also report the full power capability for 4 ports / 2 ports. For example, the full power capability report for 4 ports / 2 ports may be the same as the legacy capability report. Alternatively, for example, the full power capability report for 4 ports / 2 ports may be different from the legacy capability report.

[0072] The embodiments described above are used to illustrate embodiments of the present invention, but the present invention is not limited to these, and appropriate modifications can be made based on the embodiments described above. For example, the embodiments described above may be used individually, or a combination of several of the embodiments described above may be used.

[0073] As can be seen from the embodiments described above, by enhancing the capability reporting of terminal devices that support full power mode 2 in the embodiments of the present invention, flexibility and reliability can be improved and overhead can be reduced.

[0074] <Example of the second aspect> In the embodiments of the present invention, a capability reporting method is provided and will be described from the perspective of the network equipment.
