It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0095] To facilitate understanding of the embodiments of this application, the beam indication mechanism in the NR system will be described.

[0096] After beam measurement and beam reporting, network testing equipment can perform beam indication of downlink and uplink channels or reference signals to establish beam links between network-side equipment and terminals, enabling the transmission of channels or reference signals. For terminals, beam information may include the receive spatial domain filter used by the terminal to receive downlink channels or downlink signals and / or the transmit spatial domain filter used by the terminal to transmit uplink channels or downlink signals.

[0097] In NR systems, beam information is determined by the Quasi-co-located (QCL) Type-D in the Transmission Configuration Indicator (TCI) state. The TCI state may also include a source reference signal (RS), which the terminal can use to receive or transmit other channels or signals that have a QCL relationship with the source reference signal, by using the receive / transmit spatial filters used to receive or transmit the source reference signal.

[0098] In some scenarios, the sub-3GHz spectrum offers advantages such as wide coverage and low penetration loss, playing a crucial role in cellular network deployment due to its excellent coverage performance. On the other hand, compared to higher frequency bands, the sub-3GHz spectrum is fragmented and allocated to different wireless communication systems; regarding the spectrum occupied by mobile communication systems, competition among mobile operators further discretizes or fragments the spectrum available to each operator.

[0099] From the perspective of a single operator, almost all operators globally possess multiple Sub-3GHz frequency bands (e.g., 700MHz, 800MHz, 900MHz, 1.4GHz, 1.8GHz, 2.1GHz, 2.3GHz, or 2.6GHz bands). Related technologies, such as Carrier Aggregation (CA) / Dual Connection (DC), can aggregate multiple discrete or cross-band spectra to provide higher throughput performance for a single UE. However, CA / DA mechanisms introduce significant complexity and overhead on both the network and terminal sides. It is anticipated that if multiple discrete spectra can be aggregated into a single carrier or cell in a more efficient manner, the complexity and overhead on both sides can be significantly reduced; simultaneously, data transmission performance, such as throughput and latency, as well as operational flexibility, can be improved.

[0100] However, when multiple discrete spectrums are aggregated into a single cell or carrier, how to configure and indicate power control parameters or spatial relationship information is an urgent problem to be solved.

[0101] The wireless communication method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0102] Figure 2 is a schematic interaction diagram of an invalid communication method provided in an embodiment of this application. As shown in Figure 2, the method 200 may include at least some of the following:

[0103] S210, the terminal receives first configuration information from the network-side device. The first configuration information is used to configure at least one of the following: at least one spatial relationship information, at least one set of power control parameters, and at least one TCI status.

[0104] S220, the terminal receives first indication information from the network-side device, the first indication information being used to activate at least one of the following for the target object:

[0105] At least one spatial relationship information, at least one set of power control parameters, and at least one TCI state.

[0106] In some embodiments, the target object includes at least one of the following:

[0107] At least one frequency unit (FU);

[0108] At least one FU combination;

[0109] At least one first uplink transmission resource;

[0110] At least one first uplink transmission resource on at least one FU;

[0111] At least one first uplink transmission resource on at least one FU combination.

[0112] In some embodiments, the serving cell of the terminal, the TRP where the terminal is located, and the working carrier or bandwidth part (BWP) of the terminal are configured with multiple functions or combinations of multiple functions. These multiple functions are non-contiguous, or discrete; that is, they can be discontinuous or discrete FUs. Each FU combination may include one or more FUs, which can be non-contiguous or discrete. The FUs included in each FU combination may be reported by the terminal, configured by network-side equipment, or determined by a predefined method, etc. This application does not limit the method of determining FU combinations.

[0113] In the embodiments of this application, a FU is a group of consecutive frequency domain resources, which can be a band, carrier, subband, BWP, etc. The size of each frequency domain unit can be the same or different. For example, a cell can be composed of four frequency domain units, with sizes of 3MHz, 10MHz, 5MHz, and 5MHz respectively. Each frequency domain unit can be considered as an FU.

[0114] In some embodiments, the target object is associated with a single cell (e.g., the serving cell of the terminal), a single TRP, a single carrier (e.g., the working carrier of the terminal), or a single BWP (e.g., the BWP currently active by the terminal).

[0115] That is, the first indication information can be spatial relationship information, power control parameter set, or TCI state activation for target objects per serving cell, per carrier, per TRP, or per BWP.

[0116] In some embodiments, the at least one FU is associated with a single cell, a single TRP, a single carrier, or a single BWP. For example, the at least one FU may include multiple FUs, which may be non-contiguous FUs on a single cell, a single carrier, or a single BWP, or discrete FUs, or non-contiguous spectrum, or discrete spectrum.

[0117] Optionally, the at least one FU may include some or all of the FUs that the terminal is configured or activated.

[0118] In some embodiments, the at least one FU combination is associated with a single cell, a single TRP, a single carrier, or a single Band Width Part (BWP). Each FU combination may include one or more FUs, and the multiple FUs belonging to a single FU combination may be non-contiguous FUs, or discrete FUs, or non-contiguous spectrum, or discrete spectrum.

[0119] Optionally, the at least one FU combination may include some or all of the FU combinations that the terminal is configured or activated.

[0120] In some embodiments, the first uplink transmission resource includes, but is not limited to, at least one of the following:

[0121] Physical Uplink Control Channel (PUCCH) resources, Physical Uplink Shared Channel (PUSCH), Configured Grant-PUSCH (CG-PUSCH) resources, Sounding Reference Signal (SRS) resources, and Physical Random Access Channel (PRACH) resources.

[0122] In this application embodiment, spatial relation information may include, but is not limited to, at least one of the following:

[0123] Spatial relationship information used for downlink reception, such as the receive spatial domain filter used by the terminal to receive downlink channels or uplink signals;

[0124] Spatial relationship information used for uplink transmission, such as the transmit spatial domain filter used by the terminal to transmit uplink channels or uplink signals.

[0125] In this application embodiment, the uplink channel includes, but is not limited to, at least one of the following:

[0126] Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Configured Grant-PUSCH (CG-PUSCH), and Physical Random Access Channel (PRACH).

[0127] In the embodiments of this application, the uplink signal includes, but is not limited to, the Sounding Reference Signal (SRS).

[0128] In the embodiments of this application, the downlink channel and / or signal includes, but is not limited to, at least one of the following:

[0129] Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH).

[0130] In this application embodiment, the downlink signal includes, but is not limited to, at least one of the following:

[0131] Synchronization Signal Block (SSB) and Channel State Information Reference Signal (CSI-RS).

[0132] In the embodiments of this application, spatial relationship information, or beam information, refers to, for example, the receiving beam used by the terminal to receive the downlink channel or downlink signal, and / or the transmitting beam used by the terminal to transmit the uplink channel or uplink signal.

[0133] In some embodiments, the power control set may refer to parameters used by the terminal to perform power control, and may include, for example, at least one of the following:

[0134] Initial power parameters used for terminal transmission of preamble;

[0135] The maximum number of times the preamble can be sent;

[0136] Power adjustment step size;

[0137] The terminal's maximum transmit power;

[0138] Downlink transmission power of network-side equipment;

[0139] Road loss compensation factor alpha;

[0140] Road loss reference signal

[0141] Nominal power P0;

[0142] Closed loop index

[0143] PUCCH format adjustment factor Δ F_PUCCH ( F );

[0144] PUCCH transmission power adjustment factor Δ TF .

[0145] The TCI state in the embodiments of this application may include spatial relationship information and / or a set of power control parameters.

[0146] In other words, network-side devices can configure and indicate spatial relationship information and / or power control parameter sets through the configuration and indication of TCI status.

[0147] In some embodiments, each TCI state includes a quasi-co-located QCL type D (Type-D), a source reference signal, and a set of power control parameters associated with the TCI state, wherein the source reference signal can be considered as spatial relationship information.

[0148] When the TCI state includes spatial relationship information and a set of power control parameters, it can be assumed that network-side devices can configure or indicate spatial relationship information and power control parameters through a unified TCI state. In other words, network-side devices can perform unified beam management and power control through the TCI state.

[0149] Optionally, a TCI state may include spatial relationship information and a set of power control parameters, which may correspond to a FU, a combination of FUs, or a first uplink transmission resource.

[0150] Optionally, a TCI state may also include spatial relationship information and multiple sets of power control parameters. Each set of power control parameters corresponds to a FU or a combination of FUs or a first uplink transmission resource. The spatial relationship information corresponds to multiple FUs or combinations of FUs or multiple first uplink transmission resources. That is, network-side devices can use the same beam management for different FUs or combinations of FUs or first uplink transmission resources, but perform independent power control, thereby making power control more flexible.

[0151] Optionally, the correspondence between the multiple sets of power control parameters and the multiple FUs or FU combinations or multiple first uplink transmission resources can be predefined. For example, the first set of power control parameters in the multiple sets of power control parameters can be predefined to correspond to the first FU / FU combination that the terminal is configured / activated, or the FU / FU combination with the smallest FU / FU combination ID. The second set of power control parameters can correspond to the second FU / FU combination that the terminal is configured / activated, or the FU / FU combination with the second smallest FU / FU combination ID, and so on.

[0152] Optionally, when configuring multiple sets of power control parameters in the TCI state, the network-side device can configure the FU / FU combination or the first uplink transmission resource corresponding to each set of power control parameters in the multiple sets of power control parameters.

[0153] In some embodiments, at least one spatial relationship information configured in the first configuration information can be considered as at least one candidate spatial relationship information, or a spatial relationship information pool; at least one power control parameter set configured in the first configuration information can be considered as at least one candidate power control parameter set, or a power control parameter set pool; at least one TCI state configured in the first configuration information can be considered as at least one candidate TCI state, or a TCI state pool.

[0154] In some embodiments, the network-side device may activate at least one of the following for a target object through first indication information: at least one spatial relationship information, at least one set of power control parameters, and at least one TCI state. The at least one spatial relationship information includes some or all of the aforementioned at least one candidate spatial relationship information; the at least one set of power control parameters includes some or all of the aforementioned at least one candidate power control parameter set; and the at least one TCI state includes some or all of the aforementioned at least one candidate TCI state.

[0155] That is, the network-side device can activate part or all of the spatial relationship information pool, power control parameter set pool or TCI state pool configured in the first configuration information for the target object through the first indication information.

[0156] Therefore, in this embodiment of the application, the network-side device can configure a spatial relationship information pool, a power control parameter set pool, or a TCI state pool for the terminal through the first configuration information. Furthermore, the network-side device can dynamically activate some or all of the spatial relationship information pool, power control parameter set pool, or TCI state pool for the target object through the first indication information, which is beneficial to meet the uplink channel / or signal transmission requirements of the target object.

[0157] In some embodiments, the first indication information may include, but is not limited to, at least one of the following:

[0158] The identification information of the target object;

[0159] The identification information of at least one activated spatial relationship information corresponding to the target object;

[0160] The identification information of at least one set of activated power control parameters corresponding to the target object;

[0161] The identification information of at least one activated TCI state corresponding to the target object.

[0162] It should be noted that the target object identification information or target object index information in the embodiments of this application can be replaced with other information used to identify the target object. Similarly, the same applies to the identification information of spatial relationship information, the identification information of power control parameter set, and the identification information of TCI status. This application does not limit this.

[0163] Optionally, the target object includes at least one FU, and the identification information of the target object includes the identification information of at least one FU, such as FU Identity (FU ID) or FU Index.

[0164] Optionally, the target object includes at least one FU combination, and the identification information of the target object includes the identification information of at least one FU combination, such as FU Combination Identity (FU Combination ID) or FU Combination Index.

[0165] Optionally, the target object includes at least one first uplink transmission resource, and the identification information of the target object includes the identification information of at least one first uplink transmission resource. For example, the first uplink transmission resource is a PUCCH resource, and the identification information of the first uplink transmission resource may be a PUCCH resource ID.

[0166] Optionally, the target object includes at least one first uplink transmission resource on at least one FU, and the identification information of the target object may include the identification information of at least one FU (e.g., FU ID) and the identification information of at least one first uplink transmission resource on each FU (e.g., PUCCH Resource ID).

[0167] Optionally, the target object includes at least one first uplink transmission resource on at least one FU combination, and the identification information of the target object may include the identification information of at least one FU combination (e.g., FU Combination ID) and the identification information of at least one first uplink transmission resource on each FU combination (e.g., PUCCH Resource ID).

[0168] Optionally, the identification information of the spatial relation information can be a spatial relation info ID, the identification information of the power control parameter set can be a power control parameter set ID, and the identification information of the TCI state can be a TCI state ID.

[0169] In some embodiments, the first indication information is used to activate at least one TCI state for a target object on a first serving cell of the terminal or a first BWP of the first serving cell. That is, the first indication information can activate at least one TCI state for a target object per serving cell or per BWP.

[0170] In this case, the first indication information includes at least one of the following:

[0171] The identification information of the first serving cell;

[0172] The identification information of the first BWP in the first serving cell, such as the BWP ID;

[0173] The identification information of the target object;

[0174] The identification information of at least one TCI status.

[0175] In some embodiments, the first configuration information may be carried by static or semi-static signaling, such as by Radio Resource Control (RRC) messages.

[0176] In some embodiments, the first indication information may be carried by dynamic signaling, such as by a Media Access Control Element (MAC CE) or Downlink Control Information (DCI).

[0177] Optionally, the terminal can obtain the specific content of the spatial relationship information corresponding to the activated spatial relationship information from the first configuration information based on the identification information of the activated spatial relationship information indicated by the first indication information; or, the terminal can obtain the specific parameters of the power control parameter set corresponding to the activated power control parameter set from the first configuration information based on the identification information of the activated power control parameter set indicated by the first indication information; or, the terminal can obtain the specific content of the TCI state corresponding to the activated TCI state from the first configuration information based on the identification information of the activated TCI state indicated by the first indication information.

[0178] Therefore, network-side devices can configure at least one candidate spatial relationship information / candidate power control parameter set / candidate TCI state for the terminal through static or semi-static signaling. Each candidate spatial relationship information / candidate power control parameter set / candidate TCI state corresponds to a corresponding identification information. Furthermore, when the network-side device dynamically activates part or all of the at least one candidate spatial relationship information, at least one candidate power control parameter set, or at least one candidate TCI state for the target object through the first indication information, it only needs to indicate the identification information corresponding to the activated candidate spatial relationship information / candidate power control parameter set / candidate TCI state, without needing to indicate the complete candidate spatial relationship information / candidate power control parameter set / candidate TCI state, which can reduce the signaling overhead on the network side.

[0179] On the other hand, network-side equipment first configures at least one candidate spatial relationship information / candidate power control parameter set / candidate TCI state through static or semi-static signaling, and then flexibly indicates the activated candidate spatial relationship information / candidate power control parameter set / candidate TCI state through dynamic signaling. Compared with fixed configuration of at least one candidate spatial relationship information / candidate power control parameter set / candidate TCI state, it can improve the flexibility of spatial relationship information / power control parameter set / TCI state indication, which is conducive to meeting the uplink channel / or signal transmission requirements of different target objects.

[0180] It should be noted that, in the embodiments of this application, the configuration of the power control parameter set pool, the spatial relationship information pool, and the TCI state pool can be performed by independent signaling, or by a single signaling; similarly, the indication of the activated power control parameter set, the activated spatial relationship information, and the activated TCI state can be performed by independent signaling, or by a single signaling, and this application does not limit this.

[0181] The design of the first instruction information provided in the embodiments of this application will be described below with reference to specific examples.

[0182] Example 1:

[0183] In some embodiments, the target object includes at least one FU or at least one combination of FUs; wherein the first indication information includes at least one of the following:

[0184] The identification information of the at least one FU (e.g., FU ID) or the identification information of the at least one FU combination (e.g., FU Combination ID);

[0185] Identification information of at least one set of activated power control parameters corresponding to each FU or combination of FUs, such as Power Control Set ID;

[0186] Identification information for at least one activated spatial relation information corresponding to each FU or combination of FUs, such as Spatial relation info ID;

[0187] Identification information of at least one activated TCI state corresponding to each FU or combination of FUs, such as TCI state ID.

[0188] In one embodiment of Example 1, the network-side device can activate the corresponding power control parameter set and / or spatial relationship information for at least one FU or at least one FU combination. This addresses the issues of power control parameters and beam management for a single cell, a single TRP, a single carrier, or a single BWP, including non-contiguous spectrum, thereby improving the flexibility and efficiency of resource utilization. For the terminal, power control and beam management may be implemented by different devices. For cells containing non-contiguous spectrum, the terminal implementation may use independent power control devices or antennas for different frequencies. For example, the terminal may use a single power control device for the entire cell, but different FU / FU combinations may use different antennas, or the terminal may use a single antenna for the entire cell, but different FU / FU combinations may use different power control devices. Therefore, independently performing power control and beam management for different FU / FU combinations can avoid the impact of terminal implementation and improve system flexibility.

[0189] In one embodiment of Example 1, the network-side device can configure the TCI state pool via RRC signaling. Furthermore, the network-side device can activate the corresponding TCI state for at least one FU or at least one FU combination via MAC CE. That is, the network-side device can perform beam management and power control through unified TCI states, thereby solving the problems of power control parameters and beam management for a single cell, a single carrier, a single TRP, or a single BWP, including non-contiguous spectrum, improving the flexibility and efficiency of resource utilization. This implementation can be applied to scenarios where the terminal's power control and beam management are implemented using the same device. For cells containing non-contiguous spectrum, the network-side device can therefore perform unified power control and beam management for FU / FU combinations.

[0190] Optionally, in this embodiment 1, at least one set of activated power control parameters corresponding to each FU or each FU combination is used for at least one uplink channel or at least one uplink signal on each FU or each FU combination.

[0191] Optionally, in this embodiment 1, at least one activated spatial relationship information corresponding to each FU or each FU combination is used for at least one uplink channel or at least one uplink signal on each FU or each FU combination.

[0192] Optionally, in this embodiment 1, at least one activated TCI state corresponding to each FU or each FU combination is used for at least one uplink channel or at least one uplink signal on each FU or each FU combination.

[0193] Wherein, the at least one uplink channel includes, but is not limited to, at least one of the following:

[0194] PUCCH, PUSCH, PRACH;

[0195] The at least one uplink signal includes, but is not limited to, SRS.

[0196] Optionally, the at least one uplink channel or at least one uplink signal may be predefined by the protocol, or it may be configured or indicated by the network-side device, or it may be indicated in the first indication information. This application does not limit this.

[0197] Figure 3 is a schematic format diagram of a MAC CE provided in an embodiment of this application. The MAC CE is used to activate at least one set of power control parameters for a FU or FU combination. The FU or FU combination can be a FU or FU combination on the BWP of the serving cell.

[0198] As shown in Figure 3, the MAC CE may include at least one of the following:

[0199] Serving cell ID, BWP ID, FU ID or FU Combination ID, and at least one power control parameter set ID. The at least one power control parameter set ID can be considered as the power control parameter set ID activated for the FU or FU Combination on the BWP of the serving cell.

[0200] It should be noted that the R field in the MAC CE provided in this application represents a reserved field. The number of bits in the R field is only an example and can be flexibly adjusted according to the number of candidate power control parameter sets, candidate spatial relationship information, or candidate TCI states, or according to the number of bits required to activate candidate power control parameter sets, candidate spatial relationship information, or candidate TCI states. This application does not limit this.

[0201] It should also be noted that the MAC CE provided in this application embodiment may include a control resource pool identifier (CORESET Pool ID), which can be used to indicate the control resource pool or TRP associated with the target object. That is, this application embodiment can realize the indication of spatial relationship information / power control parameter set / TCI status on the target object associated with the control resource pool or TRP.

[0202] Figure 4 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one spatial relationship information for a FU or FU combination, where the FU or FU combination can be an FU or FU combination on the BWP of the serving cell. As shown in Figure 4, the MAC CE may include at least one of the following:

[0203] The serving cell ID, BWP ID, FU ID or FU Combination ID, and at least one spatial relationship information ID. The at least one spatial relationship information ID can be considered as the spatial relationship information ID activated for the FU or FU Combination on the BWP of the serving cell.

[0204] Figure 5 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one TCI state for a FU or FU combination, where the FU or FU combination can be an FU or FU combination on the BWP of the serving cell. As shown in Figure 5, the MAC CE may include at least one of the following:

[0205] The MAC CE format includes a serving cell ID, a BWP ID, a FU ID or FU Combination ID, and at least one TCI state ID. The at least one TCI state ID can be considered as the TCI state ID activated by the FU or FU Combination on the serving cell's BWP. In the example of Figure 5, the TCI state corresponding to the FU ID or FU Combination ID can be considered as a code point, which includes a joint TCI state, or it can include the entire set or a subset of downlink and uplink TCI states. Optionally, the MAC CE format may include a P1 indicator field to indicate the number of TCI states corresponding to the FU ID or FU Combination ID, for example, including only a subset of downlink and uplink TCI states, or including the entire set of downlink and uplink TCI states, or a specific number of included TCI states. The MAC CE format may also include a D / U indicator field to indicate whether the corresponding TCI state is an uplink TCI state or a downlink TCI state. For example, in Separate TCI mode, if the P1 indicator field can indicate that the corresponding FU ID or FU Combination ID corresponds to one TCI state or two TCI states, if it is one TCI state, then the code point can include one TCI state. Whether the TCI state is an uplink TCI or a TCI state can be determined according to the D / U indicator field.

[0206] Figure 6 is a schematic format diagram of a MAC CE provided in an embodiment of this application. The MAC CE is used to activate at least one set of power control parameters for each of a plurality of FUs or FU combinations, wherein the plurality of FUs or FU combinations may be FUs or FU combinations on the BWP of the serving cell. As shown in Figure 6, the MAC CE may include at least one of the following:

[0207] The MAC CE includes a serving cell ID, a BWP ID, multiple FU IDs or multiple FU Combination IDs, and an ID representing at least one activated power control parameter set corresponding to each FU ID or FU Combination ID. This at least one power control parameter set ID can be considered as the power control parameter set ID activated for that FU or FU Combination on the BWP of the serving cell. Optionally, each FU ID or FU Combination ID (e.g., all FUs or FU combinations contained in the serving cell or BWP) in the MAC CE corresponds to a C indication field, used to indicate whether the MAC CE includes a power control parameter set activated for the corresponding FU ID or FU Combination ID. For example, for the C indication field corresponding to the first FU ID, if the indication is yes, then the MAC CE includes a power control parameter set activated for the first FU ID, and this power control parameter set is used for at least one uplink channel or at least one uplink signal transmission on the first FU ID.

[0208] Figure 7 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one spatial relationship information for each of a plurality of FUs or FU combinations, wherein the plurality of FUs or FU combinations may be FUs or FU combinations on the BWP of the serving cell. As shown in Figure 7, the MAC CE may include at least one of the following:

[0209] The MAC CE includes a serving cell ID, a BWP ID, multiple FU IDs or multiple FU Combination IDs, and at least one activated spatial relationship information ID corresponding to each FU ID or FU Combination ID. The at least one spatial relationship information ID can be considered as the spatial relationship information ID activated for that FU or FU Combination on the BWP of the serving cell. Optionally, each FU ID or FU Combination ID in the MAC CE corresponds to a C indicator field, used to indicate whether the MAC CE includes spatial relationship information activated for the corresponding FU ID or FU Combination ID. For example, for the C indicator field corresponding to the first FU ID, if the indication is yes, then the MAC CE includes spatial relationship information activated for the first FU ID, and this spatial relationship information is used for at least one uplink channel or at least one uplink signal transmission on the first FU ID.

[0210] Figure 8 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one TCI state for each of a plurality of FUs or FU combinations, where the plurality of FUs or FU combinations may be FUs or FU combinations on the BWP of the serving cell. As shown in Figure 8, the MAC CE may include at least one of the following:

[0211] Serving cell ID, BWP ID, multiple FU IDs or multiple FU Combination IDs, and at least one activated TCI status ID corresponding to each FU ID or FU Combination ID. The at least one TCI status ID can be considered as the TCI status ID activated for that FU or FU Combination on the BWP of the serving cell.

[0212] In the example of Figure 8, the TCI state corresponding to each FU ID or FU Combination ID can be considered as a code point, which includes a Joint TCI state, or it can include the complete set or subset of downlink TCI states and uplink TCI states. Optionally, the MAC CE format may include a P1 indicator field to indicate the number of TCI states corresponding to the FU ID or FU Combination ID, for example, including only a subset of downlink and uplink TCI states, or including the complete set of downlink and uplink TCI states, or a specific number of included TCI states. The MAC CE format may also include a D / U indicator field to indicate whether the corresponding TCI state is an uplink TCI state or a downlink TCI state. For example, in Separate TCI mode, if the P1 indicator field can indicate that the corresponding FU ID or FU Combination ID corresponds to one TCI state or two TCI states, if it is one TCI state, then the code point can include one TCI state. Whether the TCI state is an uplink TCI or a TCI state can be determined according to the D / U indicator field.

[0213] It should be understood that the set of activated power control parameters, spatial relationship information or TCI states corresponding to each FU or FU combination in Figures 3 to 8 are merely examples, and this application does not limit them.

[0214] Example 2:

[0215] In some embodiments, the target object includes at least one first uplink transmission resource on at least one FU or at least one first uplink transmission resource on a combination of at least one FU;

[0216] The first indication information includes at least one of the following:

[0217] Identification information of the at least one FU or the combination of the at least one FU;

[0218] The identification information of the at least one first uplink transmission resource;

[0219] Identification information of at least one activated spatial relationship information corresponding to each first uplink transmission resource;

[0220] Identification information of at least one set of power control parameters activated for each first uplink transmission resource;

[0221] At least one activated TCI state corresponding to each first uplink transmission resource.

[0222] In one embodiment of this embodiment 2, the network-side device can activate the corresponding power control parameter set and / or spatial relationship information for at least one first uplink transmission resource on at least one FU or at least one combination of FUs, thereby solving the problem of power control parameters and beam management under discontinuous spectrum for a single cell or a single TRP or a single carrier or a single BWP, and improving the flexibility and efficiency of resource utilization.

[0223] In another embodiment of this embodiment 2, the network-side device can configure the TCI state pool through RRC signaling. Furthermore, the network-side device can activate the corresponding TCI state for at least one first uplink transmission resource on at least one FU or at least one combination of FUs through MAC CE. That is, the network-side device can perform beam management and power control through unified TCI state, thereby solving the problems of power control parameters and beam management under non-continuous spectrum for a single cell or a single TRP or a single carrier or a single BWP, and improving the flexibility and efficiency of resource utilization.

[0224] Figure 9 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one set of power control parameters for multiple PUCCH resources on a single FU or FU combination. The FU or FU combination can be an FU or FU combination on the BWP of the serving cell. As shown in Figure 9, the MAC CE may include at least one of the following:

[0225] The serving cell ID, BWP ID, FU ID or FU Combination ID, multiple PUCCH resource IDs, and at least one set ID of activated power control parameters corresponding to each PUCCH resource ID. The at least one set ID of power control parameters can be considered as the set ID of power control parameters activated for the PUCCH resources on the FU or FU Combination of the serving cell's BWP.

[0226] In the example of Figure 9, the power control parameter set corresponding to each PUCCH resource ID can be considered as a code point. Optionally, the MAC CE format may include a P1 indicator field to indicate the number of power control parameter sets corresponding to a PUCCH resource ID. The terminal then determines that number of power control parameter set IDs as the power control parameter set IDs corresponding to the PUCCH resource ID on the FU ID or FU Combination ID. Optionally, the P1 indicator field can also be replaced with an R field.

[0227] Figure 10 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one spatial relationship information for multiple PUCCH resources on a single FU or FU combination. The FU or FU combination can be an FU or FU combination on the BWP of the serving cell. As shown in Figure 10, the MAC CE may include at least one of the following:

[0228] The serving cell ID, BWP ID, FU ID or FU Combination ID, multiple PUCCH resource IDs, and at least one activated spatial relationship information ID corresponding to each PUCCH resource ID. The at least one spatial relationship information ID can be considered as the spatial relationship information ID activated for the PUCCH resource on the FU or FU Combination of the serving cell's BWP.

[0229] Figure 11 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one set of power control parameters for a PUCCH resource across multiple FUs or FU combinations. These multiple FUs or FU combinations can be FUs or FU combinations on the BWP of the serving cell. As shown in Figure 11, the MAC CE may include at least one of the following:

[0230] The system includes a serving cell ID, a BWP ID, a PUCCH resource ID, multiple FU IDs or FU Combination IDs, and at least one set ID of activated power control parameters corresponding to each FU ID or FU Combination ID. The at least one set ID of power control parameters can be considered as the set ID of power control parameters activated on the FU or FU Combination corresponding to the PUCCH resource ID on the serving cell's BWP, where the PUCCH resource corresponds to that FU ID or FU Combination ID. For example, if multiple FU IDs include a first FU ID and a second FU ID, corresponding to FU1 and FU2 respectively, and the PUCCH resource ID corresponds to the first PUCCH resource, if a terminal is configured or scheduled to transmit the first PUCCH resource on FU1 in the first time unit and on FU2 in the second time unit, then in the first time unit, when the terminal uses the first PUCCH resource to transmit PUCCH on FU1, it can use the power control parameter set corresponding to FU1 to transmit the PUCCH; in the second time unit, when the terminal uses the first PUCCH resource to transmit PUCCH on FU2, it can use the power control parameter set corresponding to FU2 to transmit the PUCCH.

[0231] Optionally, each FU ID or FU Combination ID in the MAC CE corresponds to a C indicator field, used to indicate whether the MAC CE includes a set of power control parameters activated for the corresponding FU ID or FU Combination ID, or the number of power control parameter sets activated for the corresponding FU ID or FU Combination ID. For example, for the C indicator field corresponding to the first FU ID, if the indicator includes the power control parameter set corresponding to the first FU ID, then the MAC CE includes the power control parameter set activated for the first FU ID.

[0232] Optionally, the C indicator field corresponding to each FU ID or FU Combination ID can be set before each FU ID or FU Combination ID field, or it can be set before the PUCCH resource ID field. For example, it can indicate whether the MAC CE contains a set of power control parameters activated for the corresponding FU or FU Combination, or the number of such sets, through a bitmap. As a specific example, a cell or BWP may include 4 FUs, and 8 bits can be used to indicate whether the MAC CE contains a set of power control parameters activated for each of the 4 FUs, or the number of such sets. For example, each FU corresponds to 2 bits, where a value of 0 indicates that no power control parameter set activated for that FU is included, a value of 1 indicates that the number of such sets is 1, a value of 2 indicates that the number of such sets is 2, and a value of 3 indicates that the number of such sets is 3.

[0233] Figure 12 is a schematic format diagram of a MAC CE provided in an embodiment of this application. This MAC CE is used to activate at least one spatial relationship information for a PUCCH resource across multiple FUs or FU combinations. These multiple FUs or FU combinations can be FUs or FU combinations on the BWP of the serving cell. As shown in Figure 12, the MAC CE may include at least one of the following:

[0234] The system includes a serving cell ID, a BWP ID, a PUCCH resource ID, multiple FU IDs or FU Combination IDs, and at least one activated spatial relationship information ID corresponding to each FU ID or FU Combination ID. The at least one spatial relationship information ID can be considered as the spatial relationship information ID activated on the FU or FU Combination corresponding to the FU ID or FU Combination ID for the PUCCH resource ID on the serving cell's BWP. For example, if multiple FU IDs include a first FU ID and a second FU ID, corresponding to FU1 and FU2 respectively, and the PUCCH resource ID corresponds to the first PUCCH resource, if the terminal is configured or scheduled to transmit the first PUCCH resource on FU1 in the first time unit and on FU2 in the second time unit, then in the first time unit, when the terminal uses the first PUCCH resource to transmit PUCCH on FU1, it can use the spatial relationship information corresponding to FU1 to transmit the PUCCH; in the second time unit, when the terminal uses the first PUCCH resource to transmit PUCCH on FU2, it can use the spatial relationship information corresponding to FU2 to transmit the PUCCH.

[0235] Optionally, each FU ID or FU Combination ID in the MAC CE corresponds to a C indicator field, used to indicate whether the MAC CE includes spatial relationship information activated for the corresponding FU ID or FU Combination ID, or the number of spatial relationship information activated for the corresponding FU ID or FU Combination ID. For example, for the C indicator field corresponding to the first FU ID, if the indicator includes spatial relationship information corresponding to the first FU ID, then the MAC CE includes spatial relationship information activated for the first FU ID.

[0236] Optionally, the C indicator field corresponding to each FU ID or FU Combination ID can be set before each FU ID or FU Combination ID field, or it can be set before the PUCCH resource ID field. For example, it can indicate whether the MAC CE contains spatial relationship information activated for the corresponding FU or FU Combination, or the number of spatial relationship information activated for the corresponding FU or FU Combination, through a bitmap method.

[0237] As a concrete example, a cell or BWP may include 4 FUs. An 8-bit indicator can be used to specify whether the MAC CE contains spatial relationship information activated for each of the 4 FUs, or the number of spatial relationship information activated for each of the 4 FUs. For example, each FU corresponds to 2 bits: a value of 0 indicates that no spatial relationship information activated for that FU is included; a value of 1 indicates that the number of spatial relationship information activated for that FU is 1; a value of 2 indicates that the number of spatial relationship information activated for that FU is 2; and a value of 3 indicates that the number of spatial relationship information activated for that FU is 3.

[0238] It should be understood that the set of activated power control parameters, spatial relationship information or TCI states, and the number of bits occupied by each domain corresponding to the PUCCH resource on each FU or FU combination in Figures 9 to 12 are merely examples and are not limited in this application.

[0239] Example 3

[0240] In some embodiments of this application, the first indication information includes at least one codepoint, wherein each codepoint is used to indicate activation of at least one of the following for at least one FU or at least one combination of FUs or at least one first uplink transmission resource: at least one spatial relationship information, at least one power control parameter set, and at least one TCI state.

[0241] For example, each code point includes at least one of the following:

[0242] Identification information of at least one FU or a combination of at least one FU, or identification information of at least one first uplink transmission resource;

[0243] The identification information of at least one spatial relationship information that has been activated;

[0244] Identification information of at least one set of power control parameters that are activated;

[0245] Identification information of at least one activated TCI state.

[0246] Optionally, the FU or at least one combination of FUs corresponding to each code point or the first uplink transmission resource may be predefined, or may be configured or indicated by the network-side device, for example, included in each code point.

[0247] In this embodiment 3, different FU / FU combinations, the power control parameter set of the first uplink transmission resource, spatial relationship information, and TCI state are jointly activated, which helps to save MAC CE overhead on the network side. Meanwhile, considering the frequency band relationships of different FU / FU combinations, the impact of joint activation on performance loss may be minimal.

[0248] In this embodiment 3, the network testing device can configure a pool of candidate power control parameter sets / candidate spatial relationship information / TCI states via RRC signaling, and further activate at least one power control parameter set / spatial relationship information / TCI state corresponding to a code point via MAC CE. Each code point can correspond to at least one activated power control parameter set / spatial relationship information / TCI state. The activated at least one power control parameter set / spatial relationship information / TCI state can be used for all FU / FU combinations / first uplink transmission resources configured or activated by the terminal, or for a specific FU / FU combination / first uplink transmission resource configured or activated by the terminal. The specific FU / FU combination / first uplink transmission resource can be predefined, or configured or indicated by the network side device, for example, indicated by a code point.

[0249] Figure 13 is a schematic diagram of a MAC CE format provided in an embodiment of this application. This MAC CE is used to activate four code points, each of which may contain one or more FU / FU combinations corresponding to an activated power control parameter set / spatial relationship information / TCI state. Optionally, the code point Pi may also include identification information for one or more corresponding FU / FU combinations.

[0250] For example, in the example of Figure 13, each code point can include up to three spatial relationship information pieces. These three spatial relationship information pieces can correspond one-to-one with the FU / FU combinations that the terminal is configured or activated (e.g., the first spatial relationship information corresponds to the FU / FU combination with the lowest ID, the second spatial relationship information corresponds to the FU / FU combination with the second lowest ID, and so on). The MAC CE can include a Pi indicator field (where Pi, i = 1, 2, 3, 4). The Pi indicator field is used to indicate the number of spatial relationship information pieces contained in the corresponding code point. The terminal can then obtain the corresponding number of spatial relationship information IDs as the spatial relationship information IDs included in the corresponding code point based on the number indicated by the Pi indicator field.

[0251] As a specific example, if the P1 indicator field is used to indicate that the corresponding code point includes 3 spatial relationship information, the P2 indicator field is used to indicate that the corresponding code point includes 1 spatial relationship information, the P3 indicator field is used to indicate that the corresponding code point includes 2 spatial relationship information, and the P4 indicator field is used to indicate that the corresponding code point includes 1 spatial relationship information, then the terminal can obtain 3 spatial relationship information IDs starting from byte 3 as the spatial relationship information IDs included in the first activated code point, obtain 1 spatial relationship information ID starting from byte 6 as the spatial relationship information IDs included in the second activated code point, obtain 2 spatial relationship information IDs starting from byte 7 as the spatial relationship information IDs included in the third activated code point, and obtain 1 spatial relationship information ID starting from byte 9 as the spatial relationship information IDs included in the fourth activated code point.

[0252] It should be understood that Figure 13 is only an example of code points including spatial relationship information. Code points may also include other information, such as a set of power control parameters or TCI status. In addition, the number of code points activated by MAC CE in the example of Figure 13, and the amount of spatial relationship information included in each code point, are only examples and are not limited in this application.

[0253] It is understood that the above embodiments 1, 2, 3 and other examples can be combined to solve the corresponding technical problems when they are not contradictory.

[0254] In some embodiments, the target object includes at least one first uplink transmission resource, the at least one first uplink transmission resource being associated with an FU or a combination of FUs, and the first indication information includes at least one of the following:

[0255] The identification information of the at least one first uplink transmission resource;

[0257] Identification information of at least one set of power control parameters activated for each first uplink transmission resource;

[0258] At least one activated TCI state corresponding to each first uplink transmission resource.

[0259] For example, if a first uplink transmission resource can be associated with at least one FU or at least one combination of FUs, then the spatial relationship information, power control parameter set, or TCI state activated by the network-side device for the first uplink transmission resource can be understood as: the spatial relationship information, power control parameter set, or TCI state activated by the network-side device for the first uplink transmission resource on the at least one FU or at least one combination of FUs. In this case, the network-side device may not indicate the at least one FU or at least one combination of FUs associated with the first uplink transmission resource, and the terminal defaults to using the activated spatial relationship information, power control parameter set, or TCI state for uplink transmission on the first uplink transmission resource on the at least one FU or at least one combination of FUs.

[0260] In some embodiments of this application, the method 200 further includes:

[0261] The terminal performs a first operation; wherein the first operation includes at least one of the following:

[0266] Based on the DCI of the network-side device, a target power control parameter set for uplink transmission on the target object is determined from multiple power control parameter sets;

[0267] Based on the DCI of the network-side device, determine the target TCI state for uplink transmission on the target object from multiple TCI states;

[0268] The DCI is used to indicate at least one of the following:

[0272] The target code point among multiple code points, each code point including at least one of the following: activated spatial relationship information, power control parameter set, and TCI state;

[0273] Wherein, the activated at least one spatial relationship information includes the plurality of spatial relationship information; or

[0274] The activated at least one set of power control parameters includes the plurality of power control parameter sets; or

[0275] The activated at least one TCI state includes the plurality of TCI states.

[0276] In some embodiments, the predefined rules may include, but are not limited to, at least one of the following:

[0277] The terminal uses these multiple spatial relationship information in turn to perform uplink transmission on the target object;

[0278] The terminal uses multiple sets of power control parameters in turn to perform uplink transmission on the target object;

[0279] The terminal uses multiple TCI states in turn to perform uplink transmissions on the target object;

[0280] The terminal determines a specific spatial relationship among multiple spatial relationship information (e.g., the first spatial relationship information) as the target spatial relationship information;

[0281] The terminal determines a specific set of power control parameters (e.g., the first set of power control parameters) from multiple sets of power control parameters as the target set of power control parameters;

[0282] The terminal determines the target TCI state from among multiple TCI states (e.g., the first TCI state).

[0283] Optionally, performing an uplink transfer on the target object may include at least one of the following:

[0284] If the target object includes at least one FU / FU combination, at least one uplink channel or at least one uplink signal is transmitted on at least one FU / FU combination;

[0285] If the target object includes at least one first uplink transmission resource, uplink transmission is performed on at least one first uplink transmission resource. For example, if the first uplink transmission resource is a PUCCH resource, then PUCCH is transmitted on the PUCCH resource.

[0286] If the target object includes at least one first uplink transmission resource on at least one FU / FU combination, then uplink transmission is performed on at least one first uplink transmission resource on at least one FU / FU combination. For example, if the first uplink transmission resource is a PUCCH resource, then PUCCH is transmitted on the PUCCH resource on at least one FU / FU combination.

[0287] In some embodiments, the terminal may also determine target spatial relationship information from multiple spatial relationship information based on the DCI, and further perform uplink transmission on the target object based on the target spatial relationship information; or, the terminal may determine target power control parameter set from multiple power control parameter sets based on the DCI, and further perform uplink transmission on the target object based on the target power control parameter set; or, the terminal may determine target TCI state from multiple TCI states based on the DCI, and further perform uplink transmission on the target object based on the target TCI state; or, the terminal may determine target code point from multiple code points based on the DCI, and further perform uplink transmission on the target object based on at least one of the spatial relationship information, power control parameter set, and TCI state corresponding to the target code point.

[0288] That is, in the embodiments of this application, the network-side device can configure the spatial relationship information pool, the power control parameter set pool, or the TCI state pool through RRC signaling. Furthermore, the network-side device can dynamically activate multiple spatial relationship information in the spatial relationship information pool, multiple power control parameter sets in the power control parameter set pool, or multiple TCI states in the TCI state pool for the target object through MAC CE. Alternatively, it can activate multiple code points for the target object. Each code point can include at least one of the spatial relationship information, power control parameter set, and TCI state activated for the target object. Furthermore, the network-side device can indicate the target spatial relationship information in the multiple spatial relationship information, the target power control parameter set in the multiple power control parameter sets, the target TCI state in the multiple TCI states, or the target code point in the multiple code points through DCI. This can solve the problem of power control parameters and beam management in a single cell, a single TRP, a single carrier, or a single BWP, including non-continuous spectrum.

[0289] In summary, network-side equipment configures at least one set of power control parameters and / or spatial relationship information through the first configuration information. Furthermore, it can activate the corresponding set of power control parameters and / or spatial relationship information for at least one FU or at least one FU combination through the first indication information. This solves the problems of power control parameters and beam management for a single cell, a single TRP, a single carrier, or a single BWP, including non-contiguous spectrum, improving the flexibility and efficiency of resource utilization. For the terminal, power control and beam management may be implemented by different devices. For cells containing non-contiguous spectrum, the terminal implementation may use independent power control devices or antennas for different frequencies. For example, the terminal may use a single power controller for the entire cell, but different FU / FU combinations may use different antennas; or the terminal may use a single antenna for the entire cell, but different FU / FU combinations may use different power controllers. Therefore, independently performing power control and beam management for different FU / FU combinations can avoid the impact of terminal implementation and improve system flexibility.

[0290] In other implementations, the network-side device can configure at least one candidate TCI state through the first configuration information. Furthermore, the network-side device can activate the corresponding TCI state for at least one FU or a combination of at least one FU through the first indication information. That is, the network-side device can perform beam management and power control through unified TCI state, thereby solving the problems of power control parameters and beam management under non-continuous spectrum for a single cell, a single TRP, a single carrier, or a single BWP, and improving the flexibility and efficiency of resource utilization.

[0291] In some other implementations, the network-side equipment can activate the corresponding set of power control parameters and / or spatial relationship information for at least one first uplink transmission resource on at least one FU or at least one combination of FUs, thereby solving the problems of power control parameters and beam management in a single cell or a single TRP or a single carrier or a single BWP, including non-continuous spectrum, and improving the flexibility and efficiency of resource utilization.

[0292] In some other implementations, the network-side device can configure at least one candidate TCI state through the first configuration information. Furthermore, the network-side device can activate the corresponding TCI state for at least one first uplink transmission resource on at least one FU or at least one combination of FUs through the first indication information. That is, the network-side device can perform beam management and power control through unified TCI state, thereby solving the problems of power control parameters and beam management under non-continuous spectrum for a single cell or a single TRP or a single carrier or a single BWP, and improving the flexibility and efficiency of resource utilization.
