In order to facilitate understanding of the technical solution of the embodiments of the present application, an antenna panel (panel) related to the present application is described.

With the continued evolution of antenna packaging technology, multiple antenna elements (ANTENNA ELEMENTS) may be nested with a chip to form a panel, which makes it possible to configure multiple low-correlation panels at the transmitter. Through the beam forming (Beamforming) technology of multiple antennas, the energy of the transmitted signal is collected in a certain direction for transmission, so that coverage can be effectively improved, and further, the communication performance is improved. The radio frequency links of the plurality of panels are independent, each panel of the plurality of panels can independently form a transmission beam, and the beams formed by different panels can be the same or different. So that one terminal transmitter can transmit data streams on a plurality of panels simultaneously through different beams to improve the capacity or reliability of transmission.

The terminal device needs to notify the number of antenna panels configured on the network side in the capability report. Meanwhile, the terminal device may also need to inform the network side whether it has the capability to transmit signals simultaneously on multiple antenna panels. Since the channel conditions corresponding to different panels are different, different panels need to adopt different transmission parameters according to the respective channel information. To obtain these transmission parameters, different Sounding REFERENCE SIGNAL Resource (SRS Resource) needs to be configured for different panels to obtain uplink channel information. For example, for uplink beam management, one SRS Resource set (SRS Resource set) may be configured for each panel, so that each panel performs beam management separately and determines an independent analog beam. In order to obtain precoding information for Physical Uplink SHARED CHANNEL, PUSCH (Physical Uplink SHARED CHANNEL, PUSCH) transmission, an SRS resource set may be configured for each panel to obtain transmission parameters such as a beam, a precoding vector, a transmission layer number and the like for PUSCH transmitted on the panel. Meanwhile, the multi-panel transmission can also be applied to a physical uplink control channel (Physical Uplink Control Channel, PUCCH), that is, information carried by the same PUCCH resource or PUCCH resources on the same time domain resource can be simultaneously sent to the network side through different panels. Each panel may have its own panel ID for associating different signals transmitted on the same panel, i.e. the terminal device may consider that signals associated with the same panel ID need to be transmitted from the same panel.

In order to facilitate understanding of the technical solution of the embodiment of the present application, description is made on uplink incoherent transmission related to the present application.

In an NR system, non-coherent transmission of downlink and uplink based on a plurality of transmission reception points (Transmission Reception Point, TRP) is introduced. The backhaul (backhaul) connection between the TRPs may be ideal or non-ideal, and information interaction between the TRPs under the ideal backhaul may be performed rapidly and dynamically, and information interaction between the TRPs under the non-ideal backhaul may be performed only in a quasi-static manner due to a larger time delay. In downlink incoherent transmission, multiple TRPs may independently schedule multiple physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH) transmissions of one terminal device based on different control channels, or may schedule different TRP transmissions based on the same control channel, where different TRP data is based on different transmission layers, which can only be used in the case of ideal backhaul.

In uplink incoherent transmission, different TRPs can also independently schedule PUSCH transmission of the same terminal device. Different PUSCH transmissions may configure independent transmission parameters such as beams, precoding matrices, number of layers, etc. The scheduled PUSCH transmissions may be transmitted in the same time slot or in different time slots. If the terminal device is scheduled two PUSCH transmissions simultaneously in the same slot, it is necessary to determine how to transmit based on its own capabilities. If the terminal device is configured with multiple panels and supports simultaneous PUSCH transmission on the multiple panels, the terminal device may simultaneously transmit the two PUSCHs, and the PUSCHs transmitted on different panels perform analog shaping aiming at corresponding TRPs, so as to distinguish different PUSCHs through a spatial domain, and improve uplink spectrum efficiency (as shown in fig. 2). If the terminal device has only a single panel or does not support simultaneous transmission of multiple panels, the terminal device can only transmit PUSCH on one panel. Similar to downlink, PUSCH for different TRP transmissions may be scheduled based on multiple downlink control information (Downlink Control Information, DCI) that may be carried over different sets of control resources (Control Resource Set, CORESET). Specifically, the network side configures a plurality of CORESET groups, and each TRP is scheduled based on CORESET in the respective CORESET group, that is, different TRPs can be distinguished by CORESET groups. For example, the network device may configure one CORESET group index for each CORESET, with different indexes indicating that different CORESE groups correspond to different TRPs. Likewise, PUSCH transmitted to different TRPs may be scheduled based on a single DCI, where the DCI needs to indicate the beam and Demodulation reference signal (Demodulation REFERENCE SIGNAL, DMRS) ports (as shown in fig. 3) on which PUSCH transmission layers transmitted to different TRPs are respectively based, i.e. one PUSCH different transmission layer may be transmitted on different panel.

A similar approach may also be used for PUCCH transmission. That is, the terminal device may configure different PUCCHs and transmit on different panels at the same time, and the different panels are based on different beams, and each of the beams is notified to the terminal device by respective spatial related information. Taking two different PUCCHs transmitted on different lanes as an example, as shown in fig. 4, PUCCHs transmitted on different lanes may be used to carry uplink control information (Uplink Control Information, UCI) addressed to different TRPs, e.g., UCI on lane 1 is sent to TRP1 and UCI on lane 2 is sent to TRP 2.

In order to facilitate understanding of the technical solution of the embodiments of the present application, description will be given of uplink beam management related to the present application.

In an NR system, a terminal device may employ an analog beam to transmit uplink data and uplink control information. The terminal device may perform uplink beam management based on the SRS signal to determine an analog beam for uplink transmission. Specifically, the network device may configure the terminal device with an SRS resource set 1, where the SRS resource set 1 includes N SRS resources (N > 1). The terminal equipment can adopt different beams to send the N SRS resources, the network side respectively measures the receiving quality of the N SRS resources, and K SRS resources with the best receiving quality are selected. The network side may reconfigure one SRS resource set 2, which includes K SRS resources, and make the terminal transmit the SRS resources in the SRS resource set 2 by using the analog beam used by the K selected SRS resources in the SRS resource set 1. This can be achieved by configuring the K SRS resources selected in SRS resource set 1 as reference SRS resources of the K SRS resources in SRS resource set 2, respectively. At this time, based on the SRS transmitted by the terminal device in the SRS resource set 2, the network side may select one SRS resource with the best reception quality, and notify the terminal device of the corresponding SRS resource indication (Sounding Reference SignalResource Indicator, SRI). And after the terminal equipment receives the SRI, determining the analog beam used by SRS resources indicated by the SRI as the analog beam used for transmitting the PUSCH.

In order to determine the beam used for PUCCH transmission, in NR system, the beam used for UCI transmission on each PUCCH resource is indicated by means of radio resource Control (Radio Resource Control, RRC) plus medium access Control (MEDIA ACCESS Control, MAC) signaling. Specifically, the spatial correlation information (PUCCH-spatialrelationinfo) of N PUCCHs is configured through the higher layer signaling, and then the spatial correlation information corresponding to each PUCCH resource is determined from the N PUCCHs-spatialrelationinfo through the MAC signaling.

For better understanding of the embodiments of the present application, a description will be given of a transmission configuration indicator (Transmission Configuration Indicator, TCI) state of the downlink signal transmission related to the present application.

In the NR system, the network device may configure a corresponding TCI state for each downlink signal or downlink channel, to indicate a Quasi co-located (QCL) reference signal corresponding to the target downlink signal or the target downlink channel, so that the terminal receives the target downlink signal or the target downlink channel based on the reference signal.

Wherein, a TCI state may comprise the following configuration:

A TCI state ID for identifying a TCI state;

QCL information 1;

QCL information 2.

Wherein, one QCL information further comprises the following information:

The QCL type (type) configuration may be one of QCL type a, QCL type B, QCL type C, QCL type D;

The QCL reference signal configuration includes a cell ID where the reference signal is located, a bandwidth part (Band WIDTH PART, BWP) ID, and an identification of the reference signal (which may be a channel state Information reference signal (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS) resource ID or a synchronization signal block (Synchronization Signal Block, SSB) index).

Wherein the QCL type of at least one of the QCL information 1 and the QCL information 2 must be one of typeA, typeB, typeC, and the QCL type of the other QCL information (if configured) must be QCL type D.

Wherein, the definition of different QCL type configurations is as follows:

'QCL-TypeA': (Doppler shift), doppler spread (Doppler spread), average delay (AVERAGE DELAY), delay spread (DELAY SPREAD);

'QCL-TypeB': { Doppler shift (Doppler shift), doppler spread (Doppler spread) };

'QCL-TypeC': doppler shift (Doppler shift), average delay (AVERAGE DELAY) };

'QCL-TypeD': spatial reception parameters (Spatial Rx parameter) }.

If the network device configures the QCL reference signal of the target downlink channel to be the reference SSB or the reference CSI-RS resource through the TCI state and the QCL type is configured to be typeA, typeB or typeC, the terminal device may assume that the target downlink channel is the same as the target macro-scale parameter of the reference SSB or the reference CSI-RS resource, so as to receive with the same corresponding receiving parameter, where the target macro-scale parameter is determined through QCL type configuration. Similarly, if the network device configures the QCL reference signal of the target downlink channel to be the reference SSB or the reference CSI-RS resource through the TCI state and the QCL type is configured to be type D, the terminal device may receive the target downlink channel using the same reception beam (i.e., spatial Rx parameter) as that used to receive the reference SSB or the reference CSI-RS resource. In general, the target downlink channel is transmitted with its reference time synchronization/broadcast channel (SSB/PBCH) or reference CSI-RS resource by the same TRP or the same antenna panel (panel) or the same beam at the network side. If the transmission TRP or transmission panel or transmission beam of the two downlink signals or downlink channels are different, different TCI states are typically configured.

For the downlink control channel, the TCI state may be indicated by radio resource control (Radio Resource Control, RRC) signaling or RRC signaling in combination with MAC signaling. For the downlink data channel, the available TCI state set is indicated by RRC signaling, part of the TCI states are activated by medium access Control (MEDIA ACCESS Control, MAC) layer signaling, and finally one or two TCI states are indicated from the activated TCI states by a TCI state indication field in the DCI for PDSCH scheduled by the DCI. For example, as shown in fig. 5, the network device indicates N candidate TCI states through RRC signaling, activates K TCI states through MAC signaling, and finally indicates 1 or 2 used TCI states from among the activated TCI states through a TCI state indication field in DCI.

It should be understood that in the embodiment of the present application, the Spatial information may refer to a Spatial configuration (SPATIAL SETTING) for uplink information transmission, or a Spatial relationship (Spatial relationship), for example, including but not limited to at least one of the following: antenna panels (panels), CORESET groups, reference signal sets, TCI status, beams.

In some embodiments, the set of reference signals may be a set of synchronization signal blocks (Synchronization Signal Block, SSB) or a set of channel state Information reference signals (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS) or a set of SRS.

In embodiments of the present application, the beam may also be referred to as a spatial domain transmit filter (Spatial domain transmission filter or Spatial domain filter for transmission), or a spatial domain receive filter (Spatial domain reception filter or Spatial domain filter for reception) or spatial receive parameters (Spatial Rx parameter).

It should be understood that in the embodiment of the present application, different spatial information may be indicated by different indexes or Identifiers (IDs), for example, antenna panels may be identified by a panel ID, CORESET groups are indicated by CORESET groups index, reference signal sets are indicated by reference signal set index, TCI status may be indicated by TCI, and beams may be indicated by beam IDs.

In order to better understand the embodiments of the present application, a conventional processing manner of a time-domain overlapped PUCCH or a time-domain overlapped PUCCH and PUSCH is described.

In an NR system, for example, NR version 15 (Release 15, r-15), a terminal device can transmit 2 PUCCHs at most in a time-division manner in one slot, and at least one PUCCH is a short-format PUCCH. When a plurality of PUCCHs overlap in the time domain, the timing relationship is set so that the terminal device has enough time to determine whether different PUCCHs need multiplexing, and if so, consider the time required for UCI to reassemble packets. In NR, in order to reduce interference between uplink transmissions of a terminal device, when a PUCCH and a PUSCH overlap in a time domain, UCI carried in the PUCCH is supported to be carried on the PUSCH for transmission.

Multiple PUCCHs overlap in the time domain or multiple PUCCHs and PUSCHs overlap in the time domain, the PUCCHs carry hybrid automatic repeat request acknowledgement (Hybrid automatic repeat request acknowledgement, HARQ-ACK) feedback to the PDSCH, the timing specifying the following conditions:

Condition 1: the 1 st symbol of the earliest transmitted PUCCH/PUSCH in time-domain overlapped uplink transmission is not earlier than a processing time after the last 1 symbol of a group of PDSCH corresponding to time-domain overlapped PUCCH (carrying HARQ-ACK)

By way of example only, and not by way of limitation,Wherein,N ₁ is the PDSCH processing time of the terminal device corresponding to the ith PDSCH, which is the ith processing time; μ is a configuration of subcarrier spacing (subcarrier spacing, SCS), where the value of μ is the minimum value of SCS configured as follows: SCS of the ith PDSCH, SCS of the scheduling PDCCH of the ith PDSCH, SCS of the PUCCH carrying HARQ-ACK feedback of the ith PDSCH, SCS of all the PUSCHs overlapped in the time domain; d _1,1 is predefined in the protocol.

Condition 2: the 1 st symbol of the earliest transmitted PUCCH/PUSCH in time domain overlapping uplink transmission is not earlier than the processing time after the last 1 symbol of PDCCH for Semi-PERSISTENT SCHEDULING (SPS) PDSCH release (release)The HARQ-ACK feedback corresponding to the PDCCH is carried on one of a group of PUCCHs overlapping in the time domain.

By way of example only, and not by way of limitation,Wherein,N is the processing time of the terminal equipment corresponding to the i-th PDCCH used for SPS PDSCH RELEASE; μ is a configuration of SCS, where the value of μ is the minimum value of SCS configured as follows: the i-th SCS of PDCCH for SPS PDSCH RELEASE, the i-th SCS of scheduling PDCCH of PDSCH, the SCS of PUCCH carrying HARQ-ACK feedback of i SPS PDSCH RELEASE, the SCS of PUSCH where all time domains overlap.

Condition 3: the 1 st symbol of the multiple PUCCHs with overlapping time domains is not earlier than the processing time after the last 1 st symbol of the scheduled PDCCH of the PDSCH corresponding to the PUCCH with overlapping time domains (carrying HARQ-ACKs)Or not earlier than a processing time after the last 1 symbol of a group of PDCCHs for SPSPDSCHRELEASE corresponding to a time-domain overlapped PUCCH (carrying HARQ-ACK)

And multiplexing UCI meeting the conditions to one PUCCH resource for transmission when the time sequence relation is met. For example, the PUCCH resource may be determined according to the payload of the multiplexed UCI and the PUCCH resource indication field in the DCI.

In order to better understand the embodiment of the present application, a method for determining the number of physical resource blocks (physical resource block, PRBs) of the PUCCH resource after UCI multiplexing is described.

The PUCCH resources after UCI multiplexing, that is, PUCCH resources for transmitting the multiplexed UCI, may be selected according to the total number of bits of the multiplexed UCI. The PRB number of the PUCCH resource may be determined according to at least one of: total UCI number of bits, CRC number of bits, number of time domain symbols corresponding to PUCCH formatPRB number corresponding to PUCCH formatBit number Q _m of each Resource Element (RE), subcarrier number of each Resource block corresponding to PUCCH formatUCI code rate, etc.

Then, UCI code rate R may be expressed as:

As an example, a maximum UCI code rate corresponding to each PUCCH format may be configured through PUCCH configuration information (such as PUCCH-config), which may be used for UCI multiplexing.

In the above scheme, the PUCCH with overlapped time domains, or the PUCCH with overlapped time domains and the PUSCH are associated with the same spatial information, for example, may be sent by the terminal device through the same panel. However, when the time-domain overlapped PUCCHs transmitted by the terminal device, or the time-domain overlapped PUCCHs and PUSCHs are associated with at least two pieces of spatial information, for example, transmitted through a plurality of (e.g., two or more) different panels, how the UCI corresponding to these PUCCHs/PUSCHs is multiplexed is not considered.

Based on the above problems, the present application proposes a method, a terminal device and a network device for wireless communication, where when time domain resources of at least two uplink channels overlap and/or time domains of the at least two uplink channels are in the same time unit, if the at least two uplink channels are associated with at least two spatial information, the terminal device may determine a multiplexing manner of UCI carried by the at least two uplink channels, and send UCI carried by the at least two uplink channels according to the multiplexing manner, thereby implementing multiplexing of UCI of the at least two uplink channels and improving efficiency of wireless communication.

The technical scheme of the application is described in detail below through specific embodiments.

Fig. 8 is a schematic flow chart diagram of a method 200 of wireless communication in accordance with an embodiment of the present application. The method 200 may be applied, for example, in the communication system 100 shown in fig. 1. As shown in fig. 8, the method 200 may include at least some of the following:

Optionally, S210, the terminal device determines a multiplexing manner of uplink control information UCI carried by at least two uplink channels. Wherein the at least two uplink channels are associated with at least two spatial information, time domain resources of the at least two uplink channels overlap and/or the time domain resources of the at least two uplink channels are in the same time unit.

Illustratively, the uplink channels may include at least one of PUCCH, PUSCH, SRS, PRACH, and the at least two uplink channels may be any combination of at least one of PUCCH, PUSCH, SRS, PRACH, as the application is not limited in this regard. For example, the at least two uplink channels include at least two PUCCHs, i.e., at least two PUCCHs with overlapping time domain resources and/or within the same time unit. For another example, the at least two uplink channels include at least one PUCCH and at least one PUSCH, and the at least one PUCCH and at least one PUSCH that have overlapping time domain resources and/or are in the same time unit, which is not limited by the present application.

In some embodiments, the multiplexing manner of UCI carried by at least two uplink channels includes: the at least two uplink channels are at least two PUCCHs, which carry the multiplexing mode of UCI, or the at least two uplink channels are at least one PUCCH and at least one PUSCH, which carry the multiplexing mode of UCI and at least one PUSCH.

In some embodiments, the at least two uplink channels are associated with at least two spatial information, which may be understood as at least two uplink channels being in one-to-one correspondence with the at least two spatial information, or may be understood as a plurality of uplink channels of the at least two uplink channels being associated with the same spatial information.

Illustratively, the Spatial information may refer to a Spatial configuration (SPATIAL SETTING) for uplink information transmission, or a Spatial relationship (Spatial relationship), including, for example, but not limited to, at least one of: antenna panel, CORESET groups, reference signal set, TCI state, beam. Specifically, the spatial information may be referred to the above description, and will not be repeated.

For example, in the embodiment of the present application, the time unit may be any one of a subframe (subframe), a slot (slot), a sub-slot (sub-slot), a mini-slot (mini-slot), a symbol (symbol), a slot aggregation (slot aggregation), and a time window (time window).

In some embodiments, the terminal device may receive first information, which may be used to instruct or configure the terminal device that at least two uplink channels are associated with at least two spatial information. As an example, with the first information, the terminal device may be configured or scheduled to associate a plurality of PUCCHs with n segments, e.g., transmit a plurality of PUCCHs at n segments, whose time domain resources overlap and/or within the same time unit, or configured or scheduled to associate at least one PUCCH and at least one PUSCH with n segments, e.g., transmit at least one PUCCH and at least one PUSCH at n segments, whose time domain resources overlap and/or within the same time unit.

Alternatively, the first information may be configured through RRC signaling or dynamically scheduled through DCI, which is not limited by the present application.

In some alternative embodiments, before the step S210, the network device may further send second information to the terminal device, where the second information is used to indicate time domain resources of the at least two uplink channels. Correspondingly, the terminal device may receive the second information, and determine time domain resources of the at least two uplink channels according to the second information.

The second information may be configured through RRC signaling or dynamically scheduled through DCI, which is not limited by the present application.

S220, the terminal equipment sends UCI carried by the at least two uplink channels according to the multiplexing mode. Here, UCI carried by the at least two uplink channels is UCI multiplexed according to the multiplexing manner.

The terminal device sends UCI carried by the at least two uplink channels to the network device. Correspondingly, the network device receives UCI carried by the at least two uplink channels. For example, the terminal device may receive UCI carried by the at least two uplink channels according to a multiplexing manner of the uplink control information UCI carried by the at least two uplink channels.

Optionally, S230, the network device determines a multiplexing manner of uplink control information UCI carried by the at least two uplink channels.

For example, the network device may determine a multiplexing manner of UCI carried by the at least two uplink channels before, after, or while receiving UCI carried by the at least two uplink channels.

The process of determining the multiplexing manner of UCI carried by the at least two uplink channels by the network device is the same as or similar to the process of determining the multiplexing manner of UCI carried by the at least two uplink channels by the terminal device in S210, for example, the network device and the terminal device may determine the multiplexing manner of UCI carried by the at least two uplink channels based on the same manner or rule.

Optionally, the network device may send configuration information to the terminal device, where the configuration information is used to configure a multiplexing manner of UCI carried by at least two uplink channels associated with at least two spatial information.

Optionally, the network device may further process the UCI received from the terminal device according to the multiplexing manner of UCI carried by the at least two uplink channels.

Therefore, in the embodiment of the present application, when at least two uplink channels overlap in time domain resources and/or are in the same time unit, and the at least two uplink channels are associated with at least two pieces of spatial information, the terminal device may determine a multiplexing manner of UCI carried by the at least two uplink channels, and send UCI carried by the at least two uplink channels according to the multiplexing manner, thereby implementing multiplexing of UCI of the at least two uplink channels, and improving efficiency of wireless communication.

In some optional embodiments, the multiplexing manner may include a first multiplexing manner, where the first multiplexing manner includes multiplexing UCI carried by the at least two uplink channels onto a first uplink channel for transmission. Wherein the at least two uplink channels include the first uplink channel, or the first uplink channel is an uplink channel other than the at least two uplink channels.

That is, in the first multiplexing manner, UCI carried by at least two uplink channels associated with different spatial information may be multiplexed onto the same uplink channel to be transmitted, for example, on the first uplink channel. The UCI carried by the uplink channels of each different spatial information can be jointly processed. For example, the first uplink channel may be PUCCH, or PUSCH, without limitation.

In some embodiments, the first uplink channel belongs to at least two uplink channels associated with different spatial information as described above; or the first uplink channel is an uplink channel other than the at least two uplink channels, for example, an uplink channel indicated by the network device and different from the at least two uplink channels, which is not limited in the embodiment of the present application.

Taking at least two uplink channels and at least two panels as an example, in the first multiplexing manner, when at least two uplink channels associated with at least two panels overlap in time domain resources and/or are in the same time unit, UCI carried by the uplink channels associated with each panel may be jointly processed, that is, the panels are not distinguished, and UCI carried by the uplink channels may be multiplexed onto one uplink channel to be sent.

It should be understood that, here, the spatial information including the panel is described by taking an example, when the spatial relationship includes at least one of CORESET groups, a reference signal set, a TCI state, and a beam, the first multiplexing manner of the uplink control information UCI carried by the at least two uplink channels is the same as or similar to the multiplexing manner when the spatial information includes the panel, and for example, the panel in the foregoing embodiment may be replaced by at least one of panel, CORESET groups, a reference signal set, a TCI state, a beam, and so on, which will not be repeated herein.

Optionally, when the UCI carried by the uplink channels of each different spatial information is jointly processed, the terminal device may process multiplexing of UCI carried by the uplink channels of the same spatial information (for example, the same panelID or RS index (index)) first, and then process multiplexing of UCI carried by the uplink channels associated with different spatial information.

In some optional embodiments, the multiplexing manner includes a second multiplexing manner, where the second multiplexing manner includes multiplexing UCI carried by at least one uplink channel associated with first spatial information onto a second uplink channel, and the first spatial information is one, for example, any, of the at least two spatial information, and the second uplink channel is associated with the first spatial information. Wherein the at least two uplink channels include the second uplink control channel, or the second uplink channel is an uplink channel other than the at least two uplink channels.

That is, in the second multiplexing manner, UCI carried by at least one uplink channel associated with the first spatial information may be multiplexed onto one uplink channel associated with the first spatial information, for example, the second uplink channel, where the first spatial information may be any one of the at least two spatial information, that is, UCI carried by the uplink channel associated with each spatial information may be separately processed. For example, the second uplink channel may be PUCCH, or PUSCH, without limitation.

In some embodiments, the second uplink channel belongs to at least one uplink channel associated with the first spatial information; or the first uplink channel is an uplink channel other than the at least one uplink channel associated with the first spatial information, for example, an uplink channel indicated by the network device and different from the at least one uplink channel associated with the first spatial information.

Taking at least two uplink channels and at least two panels as an example, in the second multiplexing manner, when at least two uplink channels associated with at least two panels overlap in time domain resources and/or are in the same time unit, UCI carried by the uplink channels associated with each panel may be processed separately, that is, panels are distinguished, UCI carried by at least one uplink channel associated with one of the at least two panels is multiplexed onto an uplink channel associated with the panel for transmission, or UCI carried by at least one uplink channel associated with the same panel may be multiplexed onto one uplink channel associated with the panel for transmission.

It should be understood that, here, the spatial information including the panel is described by taking an example, when the spatial relationship includes at least one of CORESET groups, a reference signal set, a TCI state, and a beam, the second multiplexing manner of the uplink control information UCI carried by the at least two uplink channels is the same as or similar to the multiplexing manner when the spatial information includes the panel, for example, the panel in the foregoing embodiment may be replaced by at least one of panel, CORESET groups, a reference signal set, a TCI state, a beam, and the like, which are not described herein.

In some alternative embodiments, the at least two uplink channels include a first group of uplink channels. The first uplink channel group has at least one of the following timing relationships:

The time interval between the first symbol of the first PUCCH or the first PUSCH and the last symbol of the second channel associated with the first uplink channel group is greater than or equal to the fourth processing time.

The first uplink channel group may include a part of the at least two uplink channels, or the first uplink channel group may include all of the at least two uplink channels, for example.

Optionally, the uplink channels in the first uplink channel group are associated with the same spatial information, or the uplink channels in the first uplink channel group are associated with at least two uplink channels meeting the above time sequence relationship.

In step S210, when the multiplexing manner of UCI carried by the at least two uplink channels is the first multiplexing manner, the uplink channels in the first uplink channel group are associated with at least two spatial information associated with the at least two uplink channels in step S210, for example, the first uplink channel group may be uplink channels associated with all the panels and satisfying the timing relationship. In step S210, when the multiplexing mode of UCI carried by the at least two uplink channels is the second multiplexing mode, the uplink channels in the first uplink channel group are associated with the same spatial information, for example, may be associated with the first spatial information above, for example, the first uplink channel group may be at least one uplink channel associated with a panel panelID of 0, which satisfies the above timing relationship.

As an example, the first uplink channel group may include at least one PUCCH, that is, the first uplink channel group may include at least one PUCCH associated with the same spatial information, or at least two PUCCHs associated with at least two spatial information, which is not limited by the present application.

As another example, the first uplink channel group may include at least one PUCCH and at least one PUSCH, that is, the first uplink channel group may include at least one PUCCH and at least one PUSCH associated with the same spatial information, or at least one PUCCH and at least one PUSCH associated with at least two spatial information, which is not limited by the present application.

Specifically, when the multiplexing mode of UCI carried by the at least two uplink channels is the first multiplexing mode, the first uplink channel group includes at least two PUCCHs associated with at least two spatial information, or at least one PUCCH and at least one PUSCH associated with at least two spatial information. And the at least two PUCCHs, or the at least one PUCCH and the at least one PUSCH, satisfy the above timing relationship. For example, one or more PUCCHs of at least two PUCCHs are associated with spatial information 1, and other PUCCHs of the at least two PUCCHs are associated with spatial relationship 2. For example, a portion of the at least one PUCCH and the at least one PUSCH is associated with spatial relationship 1 and another portion of the PUCCH and/or PUSCH is associated with spatial relationship 2.

When the multiplexing mode of UCI carried by the at least two uplink channels is the second multiplexing mode, the first uplink channel group includes at least one PUCCH or at least one PUCCH and at least one PUSCH associated with the same spatial information. The at least two PUCCHs, or at least one PUCCH and at least one PUSCH, each satisfy the above timing relationship. For example, all PUCCHs of the at least one PUCCH are associated with spatial information 1. For another example, all uplink information in the at least one PUCCH and the at least one PUSCH is associated with spatial information 1. Here, the spatial information 1 may be any one of the above-described at least two spatial information.

The first PUCCH, the first PUSCH, the PUSCH associated with the first uplink channel group, the first channel associated with the first uplink channel group, and the second channel associated with the first uplink channel group in the above-described timing relationship are described below.

For example, the first PUCCH or the first PUSCH is the earliest time domain channel in the first uplink channel group. Or the first PUCCH or the first PUSCH may be any channel in the first uplink channel group, which is not limited in the present application.

For example, the PDSCH associated with the first uplink channel group may refer to the PDSCH corresponding to the first uplink channel group. For example, when the first uplink channel group includes a PUCCH, the PDSCH corresponding to the first uplink channel group is the PDSCH corresponding to the PUCCH, and the HARQ-ACK feedback of the PDSCH is also carried and transmitted on the PUCCH.

The first additional processing time may be, for example, m symbols, m being an integer greater than or equal to 0, i being a positive integer and less than or equal to the number of uplink channels in the first group of uplink channels.

Optionally, the first additional processing time is predefined or determined according to the capability information of the terminal device, which is not limited by the present application. When the first additional processing time is m symbols, m is predefined or determined from capability information of the terminal device. I.e. the first additional processing time, or the value of m, is related to the processing capability of the terminal device for simultaneous transmission of at least two uplink channels of spatial information. As an example, m may be 0,1,2,3, etc., without limitation.

For example, the first processing time may be a maximum value of a sum of a processing time of at least one PDSCH associated with the first uplink channel group (e.g., at least one PDSCH corresponding to at least one PUCCH in the first uplink channel group) and a first additional processing time.

Illustratively, the sum of the processing time of the i-th PDSCH and the first additional processing time is a maximum value of the sum of the processing time of all PDSCH associated with the first uplink channel group and the first additional processing time.

Illustratively, no uplink channel of the at least two uplink channels is responsive to the downlink control information DCI.

Fig. 9 is a schematic diagram of PUCCH overlapping in time domain, by taking a multiplexing manner as a second multiplexing manner, where at least two uplink channels are associated with at least two channels as an example. In fig. 9, 2 PUCCHs may be transmitted through two panels (e.g., panel 1 and panel 2), respectively. Referring to fig. 9, the uplink channel group associated with Panel 1 includes 2 PUCCHs, corresponding to a first processing timeA corresponding second processing time based on the maximum value of the sum of the processing time of the 2 nd PDSCH associated with the uplink channel group and the first additional processing timeIs the maximum value of the sum of the processing time of the PUSCH associated with the PUCCH in the uplink channel group and the second additional processing time. In fig. 9, a time interval between a first symbol of a first PUCCH transmitted through panel1 and a last symbol of a PDSCH associated with the PUCCH transmitted through panel1 is greater than or equal to a first processing time corresponding to panel1The time interval between the first symbol of the first PUCCH transmitted through Panel 1 and the last symbol of the PDCCH associated with the PUCCH transmitted through Panel 1 is greater than or equal to the second processing time corresponding to Panel 1The UCI carried by the 2 PUCCHs associated with the panel 1 may be multiplexed onto one uplink channel (such as PUCCH or PUSCH) associated with the panel 1 to be transmitted.

In fig. 9, the uplink channel group associated with the panel 2 includes 2 PUCCHs, and corresponds to a first processing timeA corresponding second processing time based on the maximum value of the sum of the processing time of the 2 nd PDSCH associated with the uplink channel group and the first additional processing timeIs the maximum value of the sum of the processing time of the PUSCH associated with the PUCCH in the uplink channel group and the second additional processing time. In fig. 9, a time interval between a first symbol of a first PUCCH transmitted through panel 2 and a last symbol of a PDSCH associated with the PUCCH transmitted through panel 2 is greater than or equal to a first processing time corresponding to panel 2The time interval between the first symbol of the first PUCCH transmitted through panel 2 and the last symbol of the PDCCH associated with the PUCCH transmitted through panel 2is greater than or equal to the second processing time corresponding to panel 2The UCI carried by the 2 PUCCHs associated with the panel 2 may be multiplexed onto one uplink channel (such as PUCCH or PUSCH) associated with the panel 2 to be transmitted.

It should be understood that, here, the spatial information including the panel is described by taking an example, when the spatial relationship includes at least one of CORESET groups, a reference signal set, a TCI state, and a beam, the multiplexing manner of the uplink control information UCI of the at least two PUCCHs is the same as or similar to that when the spatial channel includes the panel, and the panel in the foregoing embodiment may be replaced with at least one of panel, CORESET groups, the reference signal set, the TCI state, the beam, and the like, which are not repeated herein.

In some optional embodiments, the third processing time is determined according to a sum of a processing time of the PDCCH for SPS PDSCH release associated with the first uplink channel group and a third additional processing time, where the third additional processing time is an additional processing time required for the terminal device to transmit at least two uplink channels associated with at least two spatial information, and may be an additional processing time required for the PDCCH for SPS PDSCH release associated with the first uplink channel group. Here, the HARQ-ACK feedback corresponding to the PDCCH is carried on the PUCCH of the first uplink channel group. Illustratively, the first additional processing time may be p symbols, p being an integer greater than or equal to 0.

Optionally, the third additional processing time is predefined or determined according to the capability information of the terminal device, which is not limited by the present application. When the third additional processing time is p symbols, p is predefined or determined from the capability information of the terminal device. I.e. the third additional processing time, or the value of p, is related to the processing capability of the terminal device for simultaneous transmission of at least two uplink channels of spatial information. As an example, p may be 0,1,2,3, etc., without limitation.

For example, the third processing time may be a sum maximum of the processing time of the PDCCH for SPSPDSCH release associated with the first uplink channel group and a third additional processing time.

Exemplary, i.e. the maximum value of the sum of the processing time associated with the first uplink channel group for SPSPDSCH released PDCCH and the third additional processing time can be expressed asWherein,Indicating the sum of the processing time of the ith PDCCH associated with the first uplink channel group for SPSPDSCH released and the third additional processing time, where i is a positive integer and is less than the number of PDCCHs associated with the first uplink channel group for SPSPDSCH released.

In some alternative embodiments, the third processing time is determined from a sixth reference subcarrier spacing.

Wherein the sixth reference subcarrier spacing is the minimum value of the subcarrier spacing of the following channels:

The ith scheduling PDCCH (physical downlink control channel) for SPSPDSCH release associated with the first uplink channel group is a positive integer, and the i is smaller than or equal to the number of scheduling PDCCHs for SPSPDSCH release associated with the first uplink channel group;

PUCCH in the first uplink channel group;

PUSCH in the first uplink channel group.

Exemplary, the ith processing time of the PDSCH released by SPSPDSCH associated with the first uplink channel group can be expressed as Wherein N is the processing time of the terminal device corresponding to the ith PDCCH for SPS PDSCH RELEASE; p is the third additional processing time; μ is a configuration of SCS, where the value of μ is the minimum value of SCS configured as follows:

The i-th SCS of PDCCH used for SPS PDSCH release associated with the first uplink channel group, i is a positive integer which is smaller than or equal to the quantity of PDCCH used for SPSPDSCH release associated with the first uplink channel group;

SCS of PUCCH carrying HARQ-ACK feedback released by ith SPS PDSCH associated with the first uplink channel group, wherein i is a positive integer which is smaller than or equal to the number of PUCCH used for SPSPDSCH released HARQ-ACK feedback associated with the first uplink channel group;

SCS of PUSCH with all time domains associated with the first uplink channel group overlapped.

In some alternative embodiments, the fourth processing time is determined according to a sum of a calculated time of CSI associated with the first uplink channel group and a fourth additional processing time. Wherein the fourth additional processing time is an additional processing time required for the terminal device to transmit the at least two uplink channels associated with the at least two spatial information, which may be an additional processing time required for the second channel associated with the first uplink channel group.

Optionally, the fourth additional processing time is predefined or determined according to the capability information of the terminal device, which is not limited by the present application. When the fourth additional processing time is y symbols, y is predefined or determined from the capability information of the terminal device. I.e. the fourth additional processing time, or the value of y, is related to the processing capability of the terminal device for simultaneous transmission of at least two uplink channels of spatial information. As an example, y may be 0,1,2,3, etc., without limitation.

The fourth additional processing time may be, for exampleWhere Z is the CSI calculation time associated with the first uplink channel group, d, T _switch,d _2,2 is the value predefined by the protocol.

For example, the fourth processing time is determined from a seventh reference subcarrier spacing that is the minimum value of the subcarrier spacing of the following channels:

Scheduling PDCCH of PUSCH in the first uplink channel group;

PDCCH for SPSPDSCHRELEASE associated with the first uplink channel group;

PUSCH in the first uplink channel group;

The first uplink channel group associated CSI-RS carrying PUSCH associated aperiodic CSI.

For example, the fourth processing time is determined from an eighth reference subcarrier spacing that is the minimum value of the subcarrier spacing of the following channels:

PUSCH in a first uplink channel group;

PUSCH-associated CSI-RS carrying aperiodic CSI.

In some alternative embodiments, the first additional processing time, the second additional processing time, the third additional processing time, and the fourth additional processing time may be the same value or the same additional processing time, which is not limited by the present application.

As a possible implementation manner, when the second multiplexing manner is adopted, UCI carried by an uplink channel in a first uplink channel group that satisfies a timing relationship is multiplexed onto an uplink channel associated with the same spatial information (such as panel 0), UCI carried by an uplink channel in a second uplink channel group that satisfies a timing relationship is multiplexed onto an uplink channel associated with the same spatial information (such as panel 1), and so on, UCI carried by an uplink channel in an nth uplink channel group that satisfies a timing relationship is multiplexed onto an uplink channel associated with the same spatial information (such as paneln-1). Here, n is the number of at least two spatial information of the simultaneous transmission uplink channel supported by the terminal device.

Therefore, the embodiment of the application can ensure that the terminal equipment has enough time to judge whether the UCI carried by different uplink channels needs to be multiplexed or not through the first uplink channel group in at least two uplink channels to meet a certain time sequence relation, and has enough time for re-grouping under the condition that the UCI carried by different uplink channels needs to be multiplexed.

In some optional embodiments, when the multiplexing mode is determined to be the first multiplexing mode, the maximum UCI code rate (maxCodeRate) corresponding to the PUCCH format associated with each of the at least two spatial information is the same or different, which is not limited by the present application.

For example, different maximum UCI code rates may be configured for PUCCH formats associated with each spatial information, respectively. Taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. Maximum UCI code rates are respectively configured for each panelID associated PUCCH format, and the maximum UCI code rates corresponding to the same PUCCH formats associated with different panelID may be the same or different, and are not limited. Taking PUCCH format 2 associated with each panelID as an example, the configuration of the maximum UCI code rate of the same PUCCH format associated with different panelID is shown in table 1 below:

TABLE 1

panelID	PUCCH format	Maximum UCI code rate
panel 0	PUCCH Format 2	MaxCodeRate-panel0
panel 1	PUCCH Format 2	MaxCodeRate-panel1
panel 2	PUCCH Format 2	MaxCodeRate-panel2
…	…	…
panel n-1	PUCCH Format 2	MaxCodeRate-paneln-1

In table 1, the maximum UCI rates corresponding to the same PUCCH formats associated with different panelID are different, maxCodeRate-panel0, …, maxCodeRate-paneln-1 respectively correspond to different maximum UCI rates.

As an example, configuration information of an uplink channel associated with at least two spatial information is independently configured.

In some embodiments, the network device configures configuration information of uplink information associated with at least two spatial information respectively through different higher layer parameters. The spatial information may be any of the foregoing spatial information, and will not be described herein. Illustratively, the uplink channel may be any of PUSCH, PUCCH, SRS, PRACH.

For example, taking one panel for each spatial information, the uplink channel is PUCCH, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. Wherein each panelID is associated with a set of PUCCH configuration information, e.g. panel x configures the higher layer parameters PUCCH-config-panelx, where x represents the index of panelID, ranging from [0, …, n-1]. For example, the higher layer parameters of panel0 to paneln-1 are respectively higher layer parameters PUCCH-config-panel0, higher layer parameters PUCCH-config-panel1, …, higher layer parameters PUCCH-config-paneln-1, etc., and the maximum UCI code rate configured for each PUCCH format is included in the higher layer parameters PUCCH-config-panelx. Alternatively, the maximum UCI code rate in PUCCH configuration information associated with different panelID may be different, for example, may be denoted as r _panelx.

For example, the higher layer parameters PUCCH-config-panelx may be as follows:

As another example, taking one panel for each spatial information, the uplink channel is PUCCH, n spatial information for n panels, panelID is [0, n-1], and n is a positive integer. Wherein a plurality panelID of the at least two spatial information associations associate the same PUCCH configuration parameter, e.g. PUCCH-config configuration, wherein the same PUCCH formats of the plurality panelID associations configure different maximum UCI code rates.

The higher layer parameter PUCCH-config may be exemplified as follows:

illustratively, UCI carried by an uplink channel associated with each spatial information is independently encoded.

It should be understood that, when the spatial information includes a panel, and the spatial relationship includes at least one of CORESET groups, a reference signal set, a TCI state, and a beam, the configuration manner of the maximum UCI code rate of the multiple PUCCH formats associated with the spatial information is the same as or similar to that when the spatial information includes a panel, for example, the panel in the foregoing embodiment may be replaced with at least one of panel, CORESET groups, a reference signal set, a TCI state, a beam, and so on, which will not be repeated herein.

Therefore, the embodiment of the application can flexibly realize independent adjustment of the maximum UCI code rate of the PUCCH formats associated with different space information by respectively configuring the maximum UCI code rates of the plurality of PUCCH formats associated with each space information and not limiting whether the maximum UCI code rates of the same PUCCH formats associated with different space information are the same.

In some optional embodiments, the at least two pieces of spatial information may include s sets of spatial information, where s is an integer greater than 1, and s is less than or equal to the number of the at least two pieces of spatial information, and the maximum UCI code rates corresponding to the same PUCCH format associated with each set of spatial information in the s sets of spatial information are the same.

For example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. Wherein, the n panelID same PUCCH formats associated with at most s different maximum UCI code rates may be configured, where s is an integer greater than 1 and less than or equal to n. By way of example, table 2 shows one example of maximum UCI code rates of the same PUCCH formats associated with different panelID, wherein the n panelID may be divided into s=2 groups, as shown in table 2, the maximum UCI code rate of PUCCH format 2 associated with at least one panelID (including panel 0 and panel 1) included in the first group panelID is configured to be MaxCodeRate first value, and the maximum UCI code rate of PUCCH format 2 associated with at least one panelID (including panels 2 to paneln-1) included in the second group panelID is configured to be MaxCodeRate second value. Illustratively, maxCodeRate first values are different than MaxCodeRate second values.

TABLE 2

panelID	PUCCH format	Maximum UCI code rate
panel 0	PUCCH Format 2	MaxCodeRate first value
panel 1	PUCCH Format 2	MaxCodeRate first value
panel 2	PUCCH Format 2	MaxCodeRate second value
…	…	…
panel n-1	PUCCH Format 2	MaxCodeRate second value

For example, when the at least two pieces of spatial information are divided into s groups of spatial information, UCI carried by an uplink channel associated with at least one piece of spatial information in the same group of spatial information is jointly encoded, and UCI carried by uplink channels associated with different groups of spatial information is independently encoded. The uplink channel is, for example, PUCCH.

Optionally, the value of s is predefined or determined according to the priority level of UCI. Illustratively, the priority level of UCI is related to the content and/or traffic type of UCI. As an example, the content of UCI may include at least one of HARQ-ACK, SR, channel state information first part (CHANNEL STATE information part1, csipart 1), channel state information second part (CHANNEL STATE information part 2, csipart 2), and the like; the UCI service types include at least one of Enhanced Mobile BroadBand-related (eMBB), ultra-high reliability low latency communication-related (Ultra-Reliable Low Latency Communications, URLLC), internet of things (Internet of Things, ioT) -related (lot), and the like.

As a specific example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. Illustratively, when n=4, s=2, the number of panels that the terminal device simultaneously transmits is 4. Of the 4 panels, 2 panels are in the first group and 2 panels are in the second group. The first group includes panelID associated identical PUCCH formats (e.g. PUCCH format 2) having a maximum UCI code rate of maxCodeRate first value and the second group panelID associated identical PUCCH formats (e.g. PUCCH format 2) having a maximum UCI code rate of maxCodeRate second value.

As another specific example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. Illustratively, when n=4, s=2, the number of panels that the terminal device simultaneously transmits is 4. The priorities of UCI carried by 2 PUCCHs associated with panelID of the 4 panels are the same, and then the 2 panels are in the first group, and the first group includes a maximum UCI code rate of the same PUCCH format (e.g. PUCCH format 2) associated with panelID as a maxCodeRate first value. The priorities of UCI carried by PUCCH associated with another 2 panelID of the 4 panels are the same, and then the other 2 panels are in a second group, and the second group includes a maximum UCI code rate of the same PUCCH format (e.g. PUCCH format 2) associated with the panel ID as maxCodeRate second value.

In other embodiments, the value of s is determined based on the spatial information and the priority level of UCI, and s may be greater than n.

For example, the priority levels of UCI carried by multiple uplink channels associated with the same spatial information may be different. In this case, the different groups may be classified according to priority levels of the different UCI. For example, the priority levels of UCI carried by a plurality of uplink channels associated with the same spatial information are 2, and then the UCI is classified into 2 groups according to the priority levels of UCI.

As a specific example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. In some embodiments, n=2, i.e. the number of panels that the terminal device simultaneously transmits is 2. The priority levels of UCI carried by PUCCH associated with 1 of the 2 panels are the same, and then the maximum UCI code rate of the same PUCCH format (e.g. PUCCH format 2) associated with panelID included in the first group by the 1 panel is maxCodeRate first value. The priorities of UCI of the plurality of PUCCH bearers associated with the other 1 panelID of the 2 panels have 2 priority levels, and then the panels are divided into 2 groups including a second group and a third group according to the priorities of UCI. The second group includes a panel ID associated with the same PUCCH format (e.g., PUCCH format 2) having a maximum UCI code rate of maxCodeRate second value. The third group includes a panel ID associated with the same PUCCH format (e.g. PUCCH format 2) having a maximum UCI code rate of maxCodeRate third value.

It should be understood that, when the spatial information includes a panel, and the spatial relationship includes at least one of CORESET groups, a reference signal set, a TCI state, and a beam, the configuration manner of the maximum UCI code rate corresponding to the same PUCCH format associated with each group of s spatial information is the same as or similar to the configuration manner when the spatial information includes a panel, for example, the panel in the foregoing embodiment may be replaced with at least one of panel, CORESET groups, a reference signal set, a TCI state, a beam, and so on, which will not be repeated herein.

Therefore, the embodiment of the application can help reduce the complexity of PUCCH resource calculation after UCI multiplexing by dividing at least two pieces of space information into s groups and the maximum UCI code rates of the same PUCCH formats associated with at least one piece of space information corresponding to each group of space information are the same.

Optionally, the terminal device may receive second information, where the second information may be used to indicate a maximum UCI code rate corresponding to the PUCCH format associated with the at least two spatial information. The second information may be configured through RRC signaling or dynamically indicated through DCI, which is not limited by the present application.

In some optional embodiments of the present application, the number of physical resource blocks (physical resource block, PRBs) of the UCI-multiplexed PUCCH resource may also be determined.

As one possible implementation manner, when different maximum UCI code rates are respectively configured for PUCCH formats associated with each spatial information, the number of UCI-multiplexed PRBs carried by the at least two uplink channels is determined by at least one of the number of UCI bits associated with each spatial information in the at least two spatial information, the number of CRC scrambling bits associated with each spatial information, and the maximum UCI code rate associated with each spatial information.

As a specific example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. Wherein, the number of PRBs after multiplexing may be related according to at least one of UCI bits associated with each panelID of the n number panelID, CRC scrambling bits associated with each panelID, and maximum UCI code rate associated with each panelID, for UCI carried by at least two uplink channels associated with the n number panelID.

For example, if the following formula (1) holds:

the number of PRBs after UCI multiplexing carried by the at least two uplink channels is the smallest satisfying the formula (1) Or the value satisfying the formula and being the smallest of the common multiples of 2,3,5Is a value of (2).

For example, if the following formula (2) holds:

The number of PRBs after UCI multiplexing carried by the at least two uplink channels is Is a value of (2).

Wherein, in the above formula (1) and formula (2),Respectively corresponding to the UCI number of bits associated with each panelID,The number of CRC scrambling bits associated with each panelID, respectively, r _panel0,…,r _paneln-1 corresponds to the maximum UCI code rate associated with each panelID, respectively, Q _m is a parameter associated with the modulation scheme (modulation scheme) or understood to be the number of bits per RE,Is the number of PRBs corresponding to the PUCCH format,Is the number of subcarriers per resource block corresponding to the PUCCH format,Is the number of time domain symbols corresponding to the PUCCH format,Is less thanIs a number of PRBs of (a).

Therefore, the embodiment of the application determines the PRB number after UCI multiplexing carried by at least two uplink channels according to at least one of UCI bit number associated with each space information, CRC scrambling bit number associated with each space information and maximum UCI code rate associated with each space information in at least two space information, so that the influence of the PRB number corresponding to at least one of UCI bit number, CRC scrambling bit number and maximum UCI code rate corresponding to each space information is reflected on the PRB number of PUCCH resources corresponding to the multiplexed UCI.

As another possible implementation manner, when the at least two pieces of spatial information include s sets of spatial information and maximum UCI code rates corresponding to the same PUCCH formats associated with each set of spatial information are the same, the number of UCI-multiplexed PRBs carried by the at least two uplink channels is determined according to at least one of the total number of UCI bits associated with each set of spatial information, the total number of CRC scrambling bits associated with each set of spatial information, and the total maximum UCI code rate associated with each set of spatial information in the s sets of spatial information.

As a specific example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. When the n panelID groups may be s groups, UCI carried by at least two uplink channels associated with each group panelID, the number of PRBs after multiplexing may be determined according to at least one of the total UCI bits associated with the group of panels, the total CRC scrambling bits associated with the group of panels, and the total maximum UCI code rate associated with the group of panels. Illustratively, s may be less than or equal to the number of panels n, or greater than or equal to the number of panels n, without limitation. Specifically, the process of dividing the n panelID into s groups may be referred to above, and will not be described herein.

For example, if the following formula (3) holds:

the number of PRBs after UCI multiplexing carried by the at least two uplink channels is the smallest satisfying the formula (3) Or the value satisfying the formula (3) and being the smallest of the common multiples of 2,3,5Is a value of (2).

For example, if the following formula (4) holds:

The number of PRBs after UCI multiplexing carried by the at least two uplink channels is

Wherein in the above formulas (3) and (4), O _{UCI_group1},…,O _{UCI_groups} corresponds to the total UCI bit number associated with each group of panel, r _{First value of},…,r _{First, the s Value of} corresponds to the maximum UCI code rate associated with each group of panel, O _CRC,group1,…,O _CRC,groups corresponds to the total CRC scrambling bit number associated with each group of panel, Q _m is a parameter related to the modulation scheme (modulation scheme) or understood as the bit number of each RE,Is the number of subcarriers per resource block corresponding to the PUCCH format,Is the number of time domain symbols corresponding to the PUCCH format,Is the number of PRBs corresponding to the PUCCH format,Is less thanIs a number of PRBs of (a).

It should be understood that, when the spatial information includes a panel, and the spatial relationship includes at least one of CORESET groups, a reference signal set, a TCI state, and a beam, the determining manner of the number of PRBs after UCI multiplexing carried by the at least two uplink channels is the same as or similar to the determining manner when the spatial information includes a panel, for example, the panel in the foregoing embodiment may be replaced with at least one of panel, CORESET groups, a reference signal set, a TCI state, a beam, and the like, which are not described herein.

Therefore, the embodiment of the application determines the PRB number after UCI multiplexing carried by at least two uplink channels according to at least one of the total UCI bit number associated with each group of space information, the total CRC scrambling bit number associated with each group of space information and the total maximum UCI code rate associated with each group of space information, so that the influence of the PRB number corresponding to at least one of the total UCI bit number, the total CRC scrambling bit number and the total maximum UCI code rate corresponding to each group of space information is reflected on the PRB number of the PUCCH resource corresponding to the UCI after multiplexing. And, by dividing at least two pieces of spatial information into s groups of spatial information and setting the same maximum UCI code rate for the same PUCCH format corresponding to each group of spatial information, the complexity of determining the PRB number of the UCI after multiplexing can be reduced.

In some alternative embodiments, the terminal device may also send capability information, for example to the network device. Illustratively, the capability information includes at least one of:

Whether uplink channels associated with at least two spatial information are supported to be simultaneously transmitted;

whether the uplink channels associated with at least two spatial information are supported to adopt different code rates or maximum UCI code rates;

The uplink channels associated with the at least two spatial information are transmitted simultaneously with the additional processing time required.

As a specific example, taking one panel for each spatial information as an example, n types of spatial information correspond to n panels, panelID is [0, n-1], and n is a positive integer. The capability information may be, for example, at least one of whether uplink channels associated with n panelID are supported for simultaneous transmission, whether a code rate or a maximum UCI code rate associated with n panelID is supported, and an additional processing time (e.g., a first additional processing time, and/or a second additional processing time, and/or a third additional processing time) for simultaneous transmission of uplink channels associated with n panelID. For example, the first additional processing time, and/or the second additional processing time, and/or the third additional processing time may be referred to the above description, and will not be repeated.

Correspondingly, the network equipment receives the capability information and acquires the capability of the terminal equipment according to the capability information.

Optionally, the network device configures or schedules the terminal device to simultaneously send uplink channels associated with at least two spatial information according to the capability information of the terminal device.

Optionally, the network configures uplink channels associated with at least two spatial information to use different code rates or maximum UCI code rates according to capability information of the terminal device.

Optionally, the network device configures the additional processing time, for example, the first additional processing time, and/or the second additional processing time, and/or the third additional processing time, according to the capability information of the terminal device.

Optionally, the terminal device performs UCI multiplexing with the first additional processing time, and/or the second additional processing time, and/or the third additional processing time according to the capability information.

Alternatively, the first additional processing time, the second additional processing time, and the third additional processing time may be the same value or the same additional processing time, which is not limited by the present application.

Alternatively, the terminal device may send uplink channels associated with at least two spatial information, such as PUCCH and/or PUSCH and/or SRS and/or PRACH, simultaneously according to its capability information.

For example, when the capability information reported by the terminal device supports simultaneous transmission of PUCCHs associated with n panelID for the terminal device, the terminal device performs UCI multiplexing according to the second multiplexing manner. And when the capability information reported by the terminal equipment is that the terminal equipment does not support simultaneous transmission of the PUCCH associated with n panelID, the terminal equipment performs UCI multiplexing according to the first multiplexing mode. When the capability information reported by the terminal equipment supports different code rates or maximum UCI code rates for the uplink channels associated with at least two space information for the terminal equipment, the terminal equipment can multiplex UCI according to a first multiplexing mode.

For example, whether the terminal device supports simultaneous transmission of uplink channels associated with at least two spatial information may be reported according to a combination of different uplink channels. Illustratively, the combination of uplink channels includes one or a combination of multiple channels of PUCCH, PUSCH, SRS, PRACH. For example, the terminal device may report whether or not simultaneous transmission of PUCCHs associated with at least two spatial information is supported, or the terminal device may report whether or not simultaneous transmission of multiple combinations such as PUCCHs and PUSCHs associated with at least two spatial information is supported, which will not be described herein.
