Specifically, if the base station indicates a DL TCI state for downlink, this TCI state can be used for the terminal's PDSCH and PDCCH (e.g., UE-dedicated PDCCH), and a portion of CSI-RS (aperiodic CSI-RS). If the base station indicates a TCI state for uplink, this TCI state can be used for the terminal's PUSCH and PUCCH, and a portion of SRS. If the base station indicates a joint TCI state, this TCI state can be used for both uplink and downlink channels / reference signals simultaneously.

[0099] In some embodiments, for the method of indicating the unified TCI state of a Multi-Transmission and Receiving Point (M-TRP), if any of the different channels, including PDCCH / PDSCH / PUCCH / PUSCH, are configured as MTRP transmissions, the base station needs to indicate the TCI state of both TRPs. The specific channel using one or both of the two TRP TCI states requires separate additional signaling. For PUCCH, it is based on Radio Resource Control (RRC) signaling to indicate which one or both of the two TRPs are used. Correspondingly, for PUSCH, the Configured Grant (CG) Type 1 PUSCH is also based on RRC, while the Dynamic Grant (DG) PUSCH and CG Type 2 PUSCH are indicated using the SRS resource set indication field in the DCI.

[0100] In some embodiments, within a 6G system, considering the combination of VMI (Very Large Scale) antennas and high-frequency bands, the Reference Signal Receiving Power (RSRP) differences between different antenna elements on a base station's antenna panel reaching the terminal can be significant. This means that for the same terminal, the optimal transmission beam for different antenna elements on the base station's antenna panel is different. Simultaneously, to reduce the complexity of UCI transmission, the PUCCH can be removed, and only the PUSCH can be used to transmit UCI. Therefore, determining the transmission beam is a problem that needs to be solved.

[0101] Therefore, this disclosure provides a communication method in which a terminal receives first information sent by a network device. The first information indicates N first transmission configuration indication states (TCI states), so that the terminal can determine M first TCI states from the N first TCI states. The M first TCI states are the second TCI states, so as to transmit uplink information based on the second TCI states. This can improve the accuracy of the transmitted beam and increase communication efficiency.

[0102] Figure 1 is a schematic diagram of a communication system architecture according to an embodiment of the present disclosure.

[0103] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0113] Figure 2 is a schematic diagram of a communication method interaction according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, the method including:

[0114] In step S2101, network device 102 sends first information to terminal 101.

[0115] In some embodiments, terminal 101 receives first information sent by network device 102.

[0116] In some embodiments, the first information is used to indicate N first TCI states.

[0117] In some embodiments, the N TCI states include N joint TCI states, each of which is used simultaneously for the transmission of uplink and downlink channels / signals. However, this disclosure is not limited to this. For example, the N first TCI states may also include N UL TCI states.

[0118] In some embodiments, the first information is carried by a MAC CE. The MAC CE indicates N first TCI states corresponding to a code point. Here, a code point is a code point in the TCI field of the DCI. That is, the MAC CE can indicate N first TCI states corresponding to a code point in the TCI field of the DCI.

[0119] In some embodiments, the first information is carried by the MAC CE and the DCI. The MAC CE indicates N first TCI states corresponding to each of the multiple code points, and the DCI indicates one code point among the multiple code points. The multiple code points are code points in the TCI field of the DCI. That is, the MAC CE can indicate N first TCI states corresponding to each of the multiple code points in the TCI field of the DCI.

[0120] Optionally, the N first TCI states can be indicated by the number of the first TCI state. For example, the N first TCI states can be indicated by TCI state ID i, where i is an integer greater than or equal to 0.

[0121] In some embodiments, a first TCI state corresponds to a first identifier and / or a second identifier. For example, each of N first TCI states corresponds to a first identifier and / or a second identifier. For example, a first CI state is used to indicate a first identifier and / or a second identifier corresponding to at least one QCL Type. The first identifier is an identifier for a reference signal resource. The second identifier is an identifier associated with a port of the reference signal resource. For example, for a single-port reference signal resource, different first TCI states can correspond to different reference signal resources, i.e., different first TCI states correspond to different first identifiers. As another example, for a multi-port reference signal resource, different first TCI states can correspond to different ports of the same reference signal resource, i.e., different first TCI states correspond to different second identifiers, and the second identifier can correspond to different ports of the same reference signal resource. For example, the first reference signal resource corresponds to ports #1 and #2. The first identifier of the first TCI state is the identifier of the first reference signal resource, and the second identifier is the identifier of port #1. The first identifier of the second TCI state is also the identifier of the first reference signal resource, and the second identifier is the identifier of port #2. Thus, the first TCI state can correspond to the first identifier and the second identifier.

[0122] In some embodiments, the second identifier includes at least one of the following: port identifier; port group identifier; antenna port identifier; antenna port group identifier; antenna subarray identifier; antenna element group identifier; CSI-RS port identifier; CSI-RS port group identifier; antenna identifier; antenna group identifier; Transmission Configuration Indicator (TCI state) state identifier; TCI state group identifier; Control Resource Set Pool identifier (CORESETPoolIndex); Transmission and Receiving Point (TRP) identifier; Access Point (AP) identifier.

[0123] In some embodiments, for a near-field terminal, the electromagnetic waves arriving at the terminal from different ports are spherical waves, and the beam targeting the terminal is a three-dimensional beam encircling the terminal. Therefore, for the terminal, the optimal beam corresponding to different ports on the network device side may be different. Thus, in this embodiment, for a near-field terminal, a first TCI state can be indicated. This first TCI state can correspond to a first identifier, a second identifier, or both. The first identifier is an identifier for a reference signal resource. The second identifier is an identifier for port association.

[0124] Optionally, the first TCI state can correspond to a first identifier. For example, the reference signal resource can be a single-port reference signal resource, with one reference signal resource corresponding to one port. Therefore, the first TCI state can correspond to different first identifiers. The terminal can determine which reference signal resource the first TCI state corresponds to based on the first identifier. The terminal does not need to know the correspondence between the reference signal resource and the port; the network device only needs to know. If the network device configures the QCL Type D of the first TCI state corresponding to the transmission of port #1 to indicate the first identifier #1, then the first TCI state can be determined for uplink information transmission of port #1. If the network device configures the QCL Type D of the first TCI state corresponding to the transmission of port #2 to indicate the first identifier #2, then the first TCI state can be determined for uplink information transmission of port #2.

[0125] Optionally, the first TCI state may correspond to the second identifier. For example, the reference signal resource may be a single-port reference signal resource or a multi-port reference signal resource, and all beams transmitting uplink information correspond to the same reference signal resource. In this case, the first TCI state may correspond only to the second identifier, meaning that the uplink information is transmitted based on one or more beams corresponding to one or more ports of the participating signal resource.

[0126] For example, if the reference signal resource is a single-port reference signal resource, and the network device configures the QCL Type D of the first TCI state corresponding to the transmission of port #1 to indicate the second identifier #1, then the first TCI state can be determined for uplink information transmission of port #1. If the network device configures the QCL Type D of the first TCI state corresponding to the transmission of port #2 to indicate the second identifier #2, then the first TCI state can be determined for uplink information transmission of port #2.

[0127] For example, consider a multi-port reference signal resource where all beams transmitting uplink information correspond to the same reference signal resource. Assume reference signal resource #1 corresponds to ports #1, #2, and #3. When the second identifier corresponding to the first TCI state is #1, the port corresponding to that first TCI state is port #1; when the second identifier corresponding to the first TCI state is #2, the port corresponding to that first TCI state is port #2; and when the second identifier corresponding to the first TCI state is #3, the port corresponding to that first TCI state is port #3. In other words, if the QCL Type D of the first TCI state indicates the second identifier #1, then the beam used for uplink information transmission in that first TCI state can be determined to be the beam corresponding to port #1 of the first reference signal resource. If the QCL Type D of the first TCI state indicates the second identifier #2, then the beam used for uplink information transmission in that first TCI state can be determined to be the beam corresponding to port #2 of the first reference signal resource. If the QCL Type D of the first TCI state indicates the second identifier #3, then the first TCI state can be determined to be the beam corresponding to the transmission of port #3 of the first reference signal resource for uplink information transmission.

[0128] Optionally, the first TCI state can correspond to a first identifier and a second identifier. For example, the reference signal resource is a multi-port reference signal resource, and the beam transmitting uplink information corresponds to different reference signal resources, or corresponds to a portion of a port of a reference signal resource.

[0129] For example, suppose the ports corresponding to reference signal resource #1 include port #1 and port 2, and the ports corresponding to reference signal resource #2 include port #1. That is, for different reference signal resources, their corresponding ports are renumbered, so there may be two ports with the number #1. If the first TCI state only corresponds to the second identifier, and the corresponding second identifier is the second identifier #1, then it cannot be determined whether the corresponding port is port #1 of reference signal resource #1 or port #1 of reference signal resource #2. Therefore, the first TCI state can correspond to the first identifier and the second identifier. If the first TCI state corresponds to the first identifier #1 and the second identifier #1, then it corresponds to port #1 of reference signal resource #1. If the first TCI state corresponds to the first identifier #2 and the second identifier #1, then it corresponds to port #1 of reference signal resource #2. In other words, if the QCL Type D of the first TCI state indicates the first identifier #1 and the second identifier #1, then this first TCI state can be determined to be the beam corresponding to the transmission of uplink information to port #1 of reference signal resource #1. If the QCL Type D of the first TCI state indicates the first identifier #2 and the second identifier #1, then the first TCI state can be determined to be the beam corresponding to the transmission of port #1 of reference signal resource #2 for uplink information transmission.

[0130] It is understood that the above examples are merely illustrative and are not intended to limit the scope of this disclosure.

[0131] It is understood that among the N first TCI states, some first TCI states may correspond to a first identifier, some first TCI states may correspond to a second identifier, and some first TCI states may correspond to both a first identifier and a second identifier. This disclosure does not limit this.

[0132] In some embodiments, for a far-field terminal, the electromagnetic waves arriving at the terminal from different ports are plane waves. Therefore, for the terminal, the optimal beam corresponding to different ports may be approximately the same. Thus, the first TCI state can be the same for different ports. The first TCI state corresponds only to the first identifier; that is, different reference signal resources can correspond to different first TCI states, but different ports of the same reference signal resource can correspond to the same first TCI state. Alternatively, the first TCI state may not correspond to the first identifier or the second identifier; this disclosure does not limit this.

[0133] Of course, for far-field terminals, the first TCI state can also correspond to the first identifier and / or the second identifier, so as to more precisely distinguish the first TCI state corresponding to different reference signal resources and / or different ports, thereby improving communication efficiency. This disclosure does not limit this.

[0134] In some embodiments, the ports in the various embodiments of this disclosure can be replaced by port groups, antenna ports, antenna port groups, antenna subarrays, antenna element groups, CSI-RS ports, CSI-RS port groups, etc. For example, the first reference signal resource is a multi-port reference signal resource, which can correspond to multiple port groups, and each port group can correspond to a beam. As another example, the second reference signal resource is a multi-port reference signal resource, which can correspond to multiple antenna subarrays, and each antenna subarray can correspond to a beam. This disclosure does not list all cases, but is not limited to them.

[0135] In some embodiments, the QCL Type includes at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, spatial Rx parameter, and spatial Tx parameter.

[0136] In some embodiments, a beam can be referred to as quasi-co-location (QCL) Type D, spatial Rx parameter or spatial reception parameter, spatial Tx parameter or spatial transmission parameter, spatial setting, spatial relation info, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, indicated TCI state, joint TCI state, downlink TCI state, uplink TCI state, unified TCI state, common TCI state, etc.

[0137] In some embodiments, the name of the first information is not limited, and it may be, for example, "instruction information", "configuration information", etc.

[0138] In step S2102, terminal 101 determines the second TCI state corresponding to the transmission of uplink information.

[0139] In some embodiments, the second TCI state is M of the N first TCI states. Here, M is a positive integer, and M is less than or equal to N, that is, N is greater than or equal to M.

[0140] In some embodiments, the second TCI state is determined by: determining it based on second information sent by the network device; or, determining the second TCI state based on default rules.

[0141] Optionally, the network device may send second information to the terminal, which may indicate a second TCI state. The terminal may determine M first TCI states, i.e., the second TCI states, from N first TCI states based on the second information.

[0142] Optionally, the second TCI state can be determined based on default rules. For example, the default rule could be that the second TCI state is the first M first TCI states of N first TCI states. Another example is that the default rule could be that M and N are the same, meaning that all N first TCI states can be used as the second TCI state. It is understood that the examples of default rules in this disclosure are merely illustrative and not limiting.

[0143] In some embodiments, the uplink information includes first uplink information, which includes uplink control information (UCI).

[0144] In some embodiments, UCI includes at least one of the following: a scheduling request (SR); a hybrid automatic repeat request-ACK knowledgement (HARQ-ACK); channel state information (CSI); and indication information defined for a specific communication scenario.

[0145] In some embodiments, HARQ-ACK can be replaced with HARQ-NACK, or it can be replaced with both HARQ-ACK and HARQ-NACK. HARQ-ACK represents positive acknowledgment, and HARQ-NACK represents negative acknowledgment.

[0146] In some embodiments, the indication information defined for a specific communication scenario may be, for example, the indication information defined in the event trigger beam report used to indicate that the terminal needs to send a beam report.

[0147] In some embodiments, the uplink information includes second uplink information, which includes UCI and non-UCI, or the second uplink information includes only non-UCI, wherein non-UCI includes other uplink information besides UCI. UCI includes at least one of the following: SR; HARQ-ACK; CSI; indication information defined for a specific communication scenario. That is, non-UCI can be uplink information other than at least one of SR, HARQ-ACK, CSI, and indication information defined for a specific communication scenario.

[0148] In some embodiments, non-UCI includes at least one of the following: uplink media access control unit (UL MAC CE); uplink synchronization channel (UL Synchronization CHannel, UL SCH); transport block (TB); code block group (CBG).

[0149] In some embodiments, the uplink information is carried by at least one of the following: PUCCH; PUSCH. The uplink information includes first uplink information and / or second uplink information; that is, the first uplink information can be carried by at least one of PUCCH and PUSCH. The second uplink information can be carried by at least one of PUCCH and PUSCH. The PUSCH includes at least one of CG Type 1 PUSCH, CG Type 2 PUSCH, and DG PUSCH.

[0150] In some embodiments, uplink information is carried by a PUSCH, and the PUSCH is a Type 1 CG PUSCH, while the second information is carried by an RRC.

[0151] As an optional embodiment, regardless of whether the uplink information is first uplink information or second uplink information, as long as it is carried by a Type 1 CG PUSCH, the second information can be carried by the RRC. The second TCI state can be M of the N first TCI states. For example, the RRC can be configured to have the same second TCI state as the first TCI state, or to configure M equal to N. The terminal can determine, based on the RRC, to use all N first TCI states as the second TCI state for transmitting uplink information. For another example, the RRC can be configured to directly use the first TCI state for transmission on the Type 1 CG PUSCH. For yet another example, the RRC can be configured to use one or more of the first TCI states as the second TCI state.

[0152] For example, if the network device determines that the uplink information is carried by a Type 1 CG PUSCH, it can configure second information through RRC so that the terminal can determine the second TCI state based on the second information. Optionally, the second information can be configured for Type 1 CG PUSCH, that is, as long as the uplink information is carried by a Type 1 CG PUSCH, the second TCI state is determined based on the same second information.

[0153] For example, if the terminal determines that the uplink information is carried by a Type 1 CG PUSCH, it can determine the second TCI state based on the second information. For instance, the network device can configure the second information through RRC, but after receiving the second information, the terminal does not determine the second TCI state based on the second information. Instead, when the terminal determines that the uplink information is carried by a Type 1 CG PUSCH, it determines the second TCI state based on the second information configured by the network device through RRC.

[0154] In some embodiments, uplink information is carried by a PUSCH and the PUSCH is a Type 2 CG PUSCH, and / or, uplink information is carried by a DG PUSCH and second information is carried by a DCI.

[0155] As an optional embodiment, regardless of whether the uplink information is first uplink information or second uplink information, as long as it is carried by a Type 2 CG PUSCH or DG PUSCH, the second information is carried by a DCI. For example, the DCI indicates which one or more of the first TCI states the second TCI state belongs to.

[0156] For example, if a network device determines that the uplink information is carried by a Type 2 CG PUSCH or a DG PUSCH, it can indicate the second information through DCI so that the terminal can determine the second TCI state based on the second information.

[0157] For example, if the terminal determines that the uplink information is carried by a Type 2 CG PUSCH or a DG PUSCH, it can determine the second TCI state based on the second information. For instance, the network device can indicate the second information via DCI, but after receiving the second information, the terminal does not determine the second TCI state based on the second information. Instead, when the terminal determines that the uplink information is carried by a Type 2 CG PUSCH or a DG PUSCH, it determines the second TCI state based on the second information configured by the network device through RRC.

[0158] In some embodiments, the uplink information includes first uplink information, which includes UCI, and the second information is carried by RRC.

[0159] As an optional embodiment, as long as the uplink information is the first uplink information, regardless of whether the first uplink information is carried by PUCCH or PUSCH, the second information can be carried by RRC. The second TCI state can be M of the N first TCI states. For example, RRC can be configured to have the same second TCI state as the first TCI state, or to configure M equal to N. The terminal can determine, based on RRC, to use all N first TCI states as the second TCI state for transmitting uplink information. For another example, RRCk can be configured to directly use the first TCI state for transmission on Type 1 CG PUSCH. For yet another example, RRC can be configured to use one or more of the first TCI states as the second TCI state.

[0160] For example, if the network device determines that the uplink information is the first uplink information, it can configure the second information through RRC so that the terminal can determine the second TCI state based on the second information. Optionally, the second information is configured for the first uplink information, that is, as long as the first uplink information is sent, the second TCI state is determined based on the same second information.

[0161] For example, if the terminal determines that the uplink information is the first uplink information, the network device can configure the second information through RRC. However, after receiving the second information, the terminal does not determine the second TCI state based on the second information. Instead, when the terminal determines that the uplink information is the first uplink information, it determines the second TCI state based on the second information configured by the network device through RRC.

[0162] In some embodiments, taking RRC as an example, the second information may include N bits, and each of the N bits may correspond to a first TCI state. If the value of a certain bit is the first value, then the first TCI state corresponding to that bit can be used as the second TCI state, that is, it belongs to one of M. If the value of that bit is the second value, then the first TCI state corresponding to that bit may not be used as the second TCI state. Here, the first value can be 1, and the second value can be 0, which is not limited in this disclosure.

[0163] In some embodiments, taking RRC as an example, the second information can include several enumerated values, such as first, second, two, etc. The terminal determines the first TCI state, second TCI state, etc., among N first TCI states as M first TCI states based on the second information. Exemplarily, "first" and "second" can refer to the order in which the first TCI states are indicated, i.e., the position of the first TCI state in the first information. Exemplarily, "first" and "second" can also be indices associated with the first TCI states. For example, while indicating N first TCI states, the first information also indicates which TCI state each first TCI state is.

[0164] In some embodiments, the name of the second information is not limited, and it may be, for example, "instruction information".

[0165] In step S2103, terminal 101 sends uplink information to network device 102.

[0166] In some embodiments, network device 102 receives uplink information sent by terminal 101.

[0167] In some embodiments, the terminal may transmit uplink information based on a second TCI state.

[0168] In some embodiments, the network device may receive uplink information, the transmission of which is based on a second TCI state.

[0169] In some embodiments, the uplink information includes first uplink information and second uplink information. If the first uplink information and the second uplink information occupy the same time domain unit, it may also include at least one of the following steps S2104 and S2105.

[0170] In step S2104, terminal 101 determines the uplink information sent on the time domain unit.

[0171] In some embodiments, if all first uplink information and second uplink information cannot be transmitted simultaneously on a time-domain unit, the uplink information transmitted on that time-domain unit can be determined. For example, only the first uplink information can be transmitted, or only the second uplink information can be transmitted. It is understood that first uplink information and second uplink information are two types of uplink information. When all first uplink information and second uplink information on a time-domain unit cannot be transmitted simultaneously, a portion of the first uplink information and a portion of the second uplink information can be transmitted. That is, the uplink information transmitted on the time-domain unit can include both first uplink information and second uplink information.

[0172] In some embodiments, if all the first uplink information and the second uplink information can be transmitted simultaneously on the time domain unit, it can be determined that the uplink information transmitted on the time domain unit includes the first uplink information and the second uplink information.

[0173] As is understood, in this embodiment, all first uplink information and second uplink information refer to all first uplink information and second uplink information occupying the same time domain unit. A time domain unit can be a symbol or a slot, but is not limited to these.

[0174] In some embodiments, uplink information transmitted on the time domain unit can be determined according to priority order.

[0175] Optionally, the first uplink information and / or the second uplink information can be sent in priority order, with the higher-priority first uplink information and / or the second uplink information being sent first, until the time unit can no longer send uplink information. The transmission of the remaining uplink information can be discarded, or the remaining uplink information can be sent in the next time unit.

[0176] Optionally, the first uplink information and / or the second uplink information can be sent in priority order, with the higher priority uplink information being sent earlier and the lower priority uplink information being sent later.

[0177] In some embodiments, the priority order includes at least one of the following: if the first uplink information and / or the second uplink information includes a UCI, the priority of the UCI is higher than that of other uplink information besides the UCI; if the first uplink information and / or the second uplink information includes uplink information carried by a PUCCH and uplink information carried by a PUSCH, the priority of the uplink information carried by the PUCCH is higher than that of the uplink information carried by the PUSCH, or the priority of the uplink information carried by the PUSCH is higher than that of the uplink information carried by the PUCCH; if the first uplink information and / or the second uplink information includes uplink information carried by a CG PUSCH and uplink information carried by a DG PUSCH, the priority of the uplink information carried by the CG PUSCH is higher than that of the uplink information carried by the DG PUSCH, or the priority of the uplink information carried by the DG PUSCH is higher than that of the uplink information carried by the CG PUSCH; or if the first uplink information and / or the second uplink information includes uplink information carried by a Type 1 CG PUSCH and uplink information carried by a Type 2 CG PUSCH... Uplink information carried by a PUSCH has a higher priority than uplink information carried by a Type 1 CG PUSCH, or vice versa.

[0178] Optionally, the priority order includes: if the first uplink information and / or the second uplink information includes a UCI, the UCI has a higher priority than other uplink information besides the UCI. For example, if the first uplink information includes a UCI and the second uplink information includes both UCI and non-UCI, then the UCI can be sent first, followed by the non-UCI. If the time unit cannot send all UCIs, the priority order of each UCI can be determined based on other priority rules, and the higher priority UCIs can be sent first.

[0179] Optionally, the priority order includes: if the first uplink information and / or the second uplink information includes uplink information carried by PUCCH and uplink information carried by PUSCH, the priority of the uplink information carried by PUCCH is higher than the priority of the uplink information carried by PUSCH, or the priority of the uplink information carried by PUSCH is higher than the priority of the uplink information carried by PUCCH.

[0180] For example, if the first uplink information and / or the second uplink information includes uplink information carried by PUCCH and uplink information carried by PUSCH, then the uplink information carried by PUCCH can be sent first, followed by the uplink information carried by PUSCH. That is, the uplink information carried by PUCCH has a higher priority than the uplink information carried by PUSCH. If the uplink information carried by PUCCH cannot be sent on the same time unit, the priority of each uplink information carried by PUCCH can be determined based on other priority rules, and the higher priority information can be sent first, until the time unit can no longer send uplink information.

[0181] For example, if the first uplink information and / or the second uplink information includes uplink information carried by PUCCH and uplink information carried by PUSCH, then the uplink information carried by PUSCH can be sent first, followed by the uplink information carried by PUCCH. That is, the uplink information carried by PUSCH has a higher priority than the uplink information carried by PUCCH. If the uplink information carried by PUSCH cannot be sent on the same time unit, the priority of each uplink information carried by PUSCH can be determined based on other priority rules, and the higher priority information can be sent first, until the time unit can no longer send uplink information.

[0182] Optionally, the priority order includes: if the first uplink information and / or the second uplink information includes uplink information carried by CG PUSCH and uplink information carried by DG PUSCH, the priority of the uplink information carried by CG PUSCH is higher than the priority of the uplink information carried by DG PUSCH, or the priority of the uplink information carried by DG PUSCH is higher than the priority of the uplink information carried by CG PUSCH.

[0183] For example, if the first uplink information and / or the second uplink information includes uplink information carried by CG PUSCH and uplink information carried by DG PUSCH, then the uplink information carried by CG PUSCH can be sent first, followed by the uplink information carried by DG PUSCH. That is, the uplink information carried by CG PUSCH has a higher priority than the uplink information carried by DG PUSCH. If the uplink information carried by CG PUSCH cannot be sent on the same time unit, the priority of the uplink information carried by CG PUSCH can be determined based on other priority rules, and the higher priority information is sent first, until the time unit can no longer send uplink information.

[0184] For example, if the first uplink information and / or the second uplink information includes uplink information carried by CG PUSCH and uplink information carried by DG PUSCH, then the uplink information carried by DG PUSCH can be sent first, followed by the uplink information carried by CG PUSCH. That is, the uplink information carried by DG PUSCH has a higher priority than the uplink information carried by CG PUSCH. If the uplink information carried by DG PUSCH cannot be sent on the same time unit, the priority of the uplink information carried by CG PUSCH can be determined based on other priority rules, and the higher priority information is sent first, until the time unit can no longer send uplink information.

[0185] Optionally, the priority includes: if the first uplink information and / or the second uplink information includes uplink information carried by a Type 1 CG PUSCH and uplink information carried by a Type 2 CG PUSCH, the priority of the uplink information carried by the Type 1 CG PUSCH is higher than the priority of the uplink information carried by the Type 2 CG PUSCH, or the priority of the uplink information carried by the Type 2 CG PUSCH is higher than the priority of the uplink information carried by the Type 1 CG PUSCH.

[0186] For example, if the first uplink information and / or the second uplink information includes uplink information carried by Type 1 CG PUSCH and uplink information carried by Type 2 CG PUSCH, then the uplink information carried by Type 1 CG PUSCH can be sent first, followed by the uplink information carried by Type 2 CG PUSCH. That is, the uplink information carried by Type 1 CG PUSCH has a higher priority than the uplink information carried by Type 2 CG PUSCH. If the uplink information carried by Type 1 CG PUSCH cannot be sent on the same time unit, the priority of the uplink information carried by Type 1 CG PUSCH can be determined based on other priority rules, and the higher priority information is sent first, until the time unit can no longer send uplink information.

[0187] For example, if the first uplink information and / or the second uplink information includes uplink information carried by Type 1 CG PUSCH and uplink information carried by Type 2 CG PUSCH, then the uplink information carried by Type 2 CG PUSCH can be sent first, followed by the uplink information carried by Type 1 CG PUSCH. That is, the uplink information carried by Type 2 CG PUSCH has a higher priority than the uplink information carried by Type 1 CG PUSCH. If the uplink information carried by Type 2 CG PUSCH cannot be sent on the same time unit, other priority rules can be used to determine that the uplink information carried by Type 2 CG PUSCH has a higher priority, until the time unit can no longer send uplink information.

[0188] It is understood that the above optional embodiments can be implemented in combination.

[0189] In some embodiments, the frequency domain resources allocated to the first uplink information and the second uplink information are different.

[0190] In some embodiments, the second information indicates the second TCI state for the first uplink information and the second uplink information respectively, and when M is greater than 1, the M first TCI states corresponding to the first uplink information are TCI states that the terminal supports sending simultaneously, and the M first TCI states corresponding to the second uplink information are TCI states that the terminal supports sending simultaneously.

[0191] In some embodiments, the frequency domain resources allocated to the first uplink information and the second uplink information are the same.

[0192] In some embodiments, the second information indicates a second TCI state for the first uplink information and the second uplink information, respectively. The second TCI state corresponding to the first uplink information and the second uplink information are L first TCI states out of N first TCI states, where L is a positive integer and L is less than or equal to M*2. For example, the second TCI state corresponding to the first uplink information is M first TCI states out of N first TCI states, and the second TCI state corresponding to the second uplink information is also M first TCI states out of N first TCI states. However, there may be the same first TCI state between the second TCI state corresponding to the first uplink information and the second uplink information. Therefore, it corresponds to L first TCI states out of N first TCI states, and L is less than or equal to M*2.

[0193] In some embodiments, the terminal determines the second TCI state corresponding to the first uplink information and the second uplink information, respectively. The second TCI state corresponding to the first uplink information and the second uplink information are L first TCI states out of N first TCI states, where L is a positive integer and L is less than or equal to M*2. For example, the second TCI state corresponding to the first uplink information is M first TCI states out of N first TCI states, and the second TCI state corresponding to the second uplink information is also M first TCI states out of N first TCI states. However, there may be the same first TCI state between the second TCI state corresponding to the first uplink information and the second uplink information. Therefore, they correspond to L first TCI states out of N first TCI states, and L is less than or equal to M*2.

[0194] For example, assume that the second TCI states corresponding to the first uplink information are TCI state#1, TCI state#2, and TCI state#3, respectively. The second TCI states corresponding to the second uplink information are TCI state#2, TCI state#3, and TCI state#4, respectively. Based on this assumption, M equals 3. Assume N equals 5, and the N first TCI states are TCI state#1, TCI state#2, TCI state#3, TCI state#4, and TCI state#5, respectively. Then the second TCI states corresponding to the first and second uplink information are TCI state#1, TCI state#2, TCI state#3, and TCI state#4 from the N first TCI states, and L equals 4.

[0195] Optionally, if the L first TCI states are TCI states that the terminal supports transmitting simultaneously, then the uplink information transmitted in the time domain unit includes the first uplink information and the second uplink information.

[0196] Optionally, if L first TCI states are not TCI states that the terminal supports transmitting simultaneously, then the uplink information transmitted in the time domain unit includes either the first uplink information or the second uplink information.

[0197] In some embodiments, the uplink information transmitted on the time domain unit includes first uplink information and second uplink information. Determining the resource locations of the first uplink information and second uplink information during actual transmission is a technical problem that needs to be solved. This disclosure provides the following method for determining the resource locations of the first uplink information and second uplink information during actual transmission:

[0198] Optionally, the first uplink information corresponds to a predetermined first resource location, and the second uplink information corresponds to a predetermined second resource location; the resource location of the first uplink information when it is actually transmitted is the first resource location; the resource location of the second uplink information when it is actually transmitted is a resource location other than the first resource location among the second resource locations. The predetermined first resource location may be the first resource location corresponding to the first uplink information determined by the terminal based on signaling indications or default rules of the network device. The signaling may include at least one of system information, RRC signaling, MAC CE, and DCI signaling, but is not limited to this. Correspondingly, the predetermined second resource location may be the second resource location corresponding to the second uplink information determined by the terminal based on signaling indications or default rules of the network device. The signaling indication includes at least one of system information, RRC signaling, MAC CE, and DCI signaling, but is not limited to this.

[0199] For example, the resource location corresponding to the first uplink message remains unchanged, while the resource occupied by the second uplink message is less than the resource corresponding to the first uplink message.

[0200] Optionally, the uplink information transmitted in the time domain unit includes first uplink information and second uplink information. The first uplink information corresponds to a predetermined first resource location, and the second uplink information corresponds to a predetermined second resource location. The resource location of the first uplink information when it is actually transmitted is a specified resource location in the second resource location. The resource location of the second uplink information when it is actually transmitted is a resource location in the second resource location other than the specified resource location.

[0201] For example, the resource location corresponding to the first uplink information is the resource at a specified location of the resource occupied by the second uplink information, such as a specified symbol and / or a specified resource block (RB) location. The resource occupied by the second uplink information is less than the resource at the specified location. For example, the specified location includes, but is not limited to, the lowest frequency RB location on the first symbol.

[0202] Optionally, the bit positions corresponding to the first uplink information and the second uplink information are determined based on a default rule. The default rule can be that the first uplink information and the second uplink information have bits lower than the bits of the second uplink information. However, this disclosure is not limited to this.

[0203] In some embodiments, the N first TCI states correspond to at least one Bandwidth Part (BWP) identifier and / or at least one Component Carrier (CC) identifier; if the CC identifier is an identifier in the CC list, then the N first TCI states apply to all BWPs on all CCs in the CC list.

[0204] In step S2105, terminal 101 determines the TCI state when sending uplink information in the time domain unit.

[0205] In some embodiments, the terminal can determine the TCI state when transmitting uplink information on the time domain unit.

[0206] For example, if the uplink information sent by the terminal includes first uplink information, then the TCI state when sending uplink information in the time domain unit includes the second TCI state corresponding to the first uplink information. The second TCI state corresponding to the first uplink information is M of the N first TCI states, which can be determined based on default rules or second information. For details, please refer to the above embodiments, and this disclosure will not repeat them.

[0207] For example, if the uplink information sent by the terminal includes second uplink information, then the TCI state when sending uplink information in the time domain unit includes the second TCI state corresponding to the second uplink information. The second TCI state corresponding to the second TCI state is M of the N first TCI states. For details, please refer to the above embodiments, and this disclosure will not repeat them.

[0208] For example, if the uplink information sent by the terminal includes first uplink information and second uplink information, then the TCI state when sending uplink information in the time domain unit includes the second TCI state corresponding to the first uplink information and the second TCI state corresponding to the second uplink information. The second TCI state corresponding to the first uplink information and the second TCI state corresponding to the second uplink information are L of the N first TCI states, where L is less than or equal to M*2. They can be determined based on default rules or second information. For details, please refer to the above embodiments. This disclosure will not repeat them here.

[0209] For example, if the uplink information sent by the terminal includes first uplink information and second uplink information, then the TCI state when sending uplink information in the time domain unit includes the second TCI state corresponding to the first uplink information or the second TCI state corresponding to the second uplink information. The second TCI state corresponding to the first uplink information and the second TCI state corresponding to the second uplink information can be determined based on default rules or second information. For details, please refer to the above embodiments, and this disclosure will not repeat them.

[0250] In some embodiments, the above methods may include the methods of the embodiments related to the communication system 100, terminal 101, and network device 102, which will not be described again here.

[0251] This disclosure provides a method for determining the transmit beam of a PUSCH.

[0252] In some embodiments, the terminal receives first information indicating a first TCI state, which contains N TCI states, where N is a positive integer (typically, N is greater than 1).

[0253] In some embodiments, the N TCI states include N joint TCI states, each of which is used simultaneously for the transmission of uplink and downlink channels / signals.

[0254] In some embodiments, the TCI state is used to indicate the RS ID or RS ID plus a first ID corresponding to at least one QCL Type, the first ID including at least one of the following: port ID, port group ID, antenna port ID, antenna port group ID, antenna subarray ID, antenna element group ID, CSI-RS port ID, CSI-RS port group ID, antenna ID, and antenna group ID.

[0255] In some embodiments, different QCL Types include at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, and Spatial Rx parameter.

[0256] In some embodiments, the TCI state can also be replaced by beam, spatialrelationinfo, spatial Tx parameter, Tx / Rx filtering parameter, spatial filter setting, etc.

[0257] In some embodiments, the terminal receives second information, which is used to indicate the second TCI state used when the terminal transmits uplink information. The second TCI state is M of N TCI states, where M is a positive integer not greater than N.

[0258] In some embodiments, the uplink information is the first uplink information.

[0259] In some embodiments, the first uplink information is used to transmit UCI, uplink control information, including at least one of the following.

[0260] Scheduling request;

[0261] HARQ-ACK feedback;

[0262] CSI;

[0263] Other UCIs, such as the indication information defined in Event Trigger Beam Report, are used to indicate that the terminal needs to send a beam report.

[0264] In some embodiments, the second information includes at least one of RRC, MAC CE, and DCI.

[0265] Optionally, the second information is RRC. The second information is N bits, with 1 bit corresponding to each TCI state, and this bit being '1' indicates that it belongs to one of the M states.

[0266] In some embodiments, the first uplink information is carried on PUCCH or PUSCH.

[0267] In some embodiments, the first uplink information is carried on CG Type 1 PUSCH.

[0268] In some embodiments, the uplink information is the second uplink information.

[0269] In some embodiments, the second uplink information is used to transmit UCI and non-UCI, or only non-UCI. Non-UCI includes: UL MAC CE, UL-SCH, TB, CBG.

[0270] In some embodiments, the second information includes at least one of RRC, MAC CE, and DCI.

[0271] Optionally, when the second uplink information is CG Type 1 PUSCH, the second information is RRC. The second information is N bits, with 1 bit corresponding to each TCI state, and this bit being '1' indicates that it belongs to one of the M states.

[0272] Optionally, when the second uplink information is CG Type 2 PUSCH or DG PUSCH, the second information is DCI. The second information is N bits, with 1 bit corresponding to each TCI state, and this bit being '1' indicates that it belongs to one of M states.

[0273] In some embodiments, each SRS resource set corresponds to 1 bit, and each SRS resource set corresponds to an indication of a TCI state.

[0274] In some embodiments, when the first uplink information and the second uplink information are transmitted on the same symbol, at least one of the following is determined:

[0275] Send the first uplink message;

[0276] Send the second uplink message;

[0277] The TCI state when uplink transmission is performed on this symbol.

[0278] In some embodiments, the determination is based on at least one of the following:

[0279] Signaling determination for base station configuration

[0280] For example, if the base station is configured with priorities, the priorities include:

[0281] UCI has high priority;

[0282] CG PUSCH has a higher priority, while DG PUSCH has a lower priority.

[0283] CG PUSCH has a lower priority, while DG PUSCH has a higher priority.

[0284] PUCCH has a higher priority, while PUSCH has a lower priority.

[0285] PUCCH has a lower priority, while PUSCH has a higher priority.

[0286] In some embodiments, the priority rule is determined based on a default rule. For example, the default is one of the priority rules mentioned above.

[0287] In some embodiments, the higher priority is determined by the above method, and the corresponding TCI state of the higher priority is used for transmission.

[0288] In some embodiments, the frequency domain resources allocated to the first uplink information and the second uplink information are different.

[0289] In some embodiments, the M first TCI states corresponding to the first uplink information indicated by the second information are TCI states that the terminal supports transmitting simultaneously. The M second TCI states corresponding to the second uplink information indicated by the second information are TCI states that the terminal supports transmitting simultaneously.

[0290] In some embodiments, if the set of third TCI states corresponding to the set of M first TCI states and M second TCI states (excluding duplicates) is also a set of TCI states that the terminal supports transmitting simultaneously, then the terminal can transmit the first uplink information and the second uplink information simultaneously. Otherwise, only the higher priority information is transmitted.

[0291] In some embodiments, the frequency domain resources allocated to the first uplink information and the second uplink information are the same.

[0292] In some embodiments, if the set of third TCI states corresponding to the set of M first TCI states and M second TCI states (excluding duplicates) is also a set of TCI states that the terminal supports transmitting simultaneously, then the terminal can transmit the first uplink information and the second uplink information simultaneously. The resource position corresponding to the first uplink information remains unchanged, while the resources occupied by the second uplink information are reduced by a portion of the resources corresponding to the first uplink information. Alternatively, the resource position corresponding to the first uplink information is a specified position of the resources occupied by the second uplink information, such as a specified symbol and / or a specified RB position. The resources occupied by the second uplink information are reduced by a specified position of the resources. Alternatively, the bit positions corresponding to the first and second uplink information are determined based on default rules, such as transmitting the first uplink information in the lower bit positions. Otherwise, only the higher priority bit is transmitted.

[0293] In some embodiments, the first indication information is MAC CE, where MAC CE indicates N TCI states corresponding to one codepoint of a TCI field of a DCI. Alternatively, the first indication information is MAC CE+DCI, where MAC CE indicates N TCI states corresponding to multiple codepoints of a TCI field of a DCI, and DCI is used to indicate one codepoint.

[0294] In some embodiments, the first indication information includes: a number corresponding to each TCI state, such as which number it is.

[0295] In some embodiments, based on sixteen, at least one of the N TCI states indicated by the first indication information can also be used for the transmission of at least one other channel / signal:

[0296] In some embodiments, at least one channel is at least one of the following: PDSCH, PDCCH

[0297] In some embodiments, the first indication information indicates at least one BWP ID and / or at least one CC ID corresponding to N TCI states. If the CC ID is one of the CC IDs in one of the CC lists, it means that the N TCI states indicated by the first indication information apply to all BWPs on all CCs in the CC list (i.e., the BWP ID can be ignored).

[0298] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0299] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits.
