Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a method, apparatus and terminal for simultaneous transmission on a Physical Uplink Shared Channel (PUSCH). Background Technology

[0002] Due to limitations in the transmission capacity of the terminal antenna panels, the 5G communication protocol Rel-17 only discusses a scheme where two antenna panels switch transmissions in a time-division manner to improve PUSCH transmission reliability.

[0023] Firstly, in related technologies, there are two antenna panels that can simultaneously receive PDSCH. The reception schemes for simultaneously receiving the Physical Downlink Shared Channel (PDSCH) include: Space Division Multiplexing (SDM), Frequency Division Multiplexing (FDM) (including FDM-A and FDM-B), and Single Frequency Network (SFN) proposed for high-speed rail scenarios.

[0024] I. For SDM

[0025] In the absence of an SFN scheme in the higher-layer signaling, if the Downlink Control Information (DCI) format (1-1 or 1-2) carries two Transmission Configuration Indicator (TCI) states, and the Demodulation Reference Signal (DMRS) port indications include two Code Division Multiplexing (CDM) groups, then the terminal considers the PDSCH to be received using the SDM transmission scheme. In this scheme, the PDSCH occupies one Transport Block (TB) (also referred to as a "transmit data block"), and it is a Redundant Version (RV) channel-coded version. The size of the TB block is calculated based on all transport layers from both Transmission Reception Points (TRPs), and different TRPs use different CDM groups for their DMRS ports.

[0026] II. For FDM-A

[0027] When the higher-layer signaling is configured with the FDM-A scheme, if the DCI signaling of DCI format 1-1 or 1-2 carries two TCI states and the DMRS ports indicate that it contains one CDM group, then the terminal considers that the FDM-A transmission scheme is being used to receive PDSCH simultaneously. Specifically, when the precoding granularity: the Precoding Resource Block Group (PRG) configuration information is wideband, the frequency domain information carried in the DCI indicates that the frequency domain resources indicated in the Frequency Domain Resource Allocation (FDRA) are divided into two parts: the first part is associated with the first TCI state and comes from TRP1; the second part is associated with the second TCI state and comes from TRP2.

[0028] PDSCH occupies 1 TB, and the TB block size is calculated based on the frequency domain resources indicated by the entire FDRA. One channel coding RV is configured, and the encoded bit information is divided into two parts, which are mapped to different TRPs respectively.

[0029] III. For FDM-B

[0030] The FDM-B scheme is basically the same as that of FDM-A. The difference is that in FDM-B, two identical TB blocks are rate matched based on two configured RV redundancy versions (i.e., the same TB is rate matched twice using two RV redundancy versions), and then mapped to different TRPs respectively.

[0031] IV. For SFN

[0032] Each TB block undergoes channel coding and rate matching once, and is then copied to two TRPs. Both TRPs transmit the same PDSCH (including DMRS) signal, and each layer of data stream is simultaneously associated with two different TCI states. DMRSPorts indicates whether the data streams are in the same or different CDM groups.

[0033] Secondly, in related technologies, the uplink PUSCH supports alternating transmission between two antenna panels. Specifically, the higher layers configure two Sounding Reference Signal (SRS) resource sets for the terminal, each SRS resource set being associated with one antenna panel. When the PUSCH operates in codebook mode, the DCI signaling of DCI format 0-1 or 0-2 carries two Transmitted Precoding Matrix Indicator (TPMI) fields, with the transmitted data stream information located in the first TPMI field. When the PUSCH operates in non-codebook mode, the DCI signaling of DCI format 0-1 or 0-2 carries two SRS Resource Indicator (SRI) fields, with the transmitted data stream information located in the first SRI field.

[0034] The embodiments of this application propose a scheme for simultaneous transmission of uplink PUSCH in a multi-panel configuration, and propose how to configure the related SRS resource set signaling under this scheme, how to indicate the TPMI / RI domain and SRI domain, the related influence of DMRS pilot and phase tracking reference signal (PTRS) pilot, and some scheduling restrictions on frequency domain resource allocation under different transmission schemes.

[0035] The following description, in conjunction with the accompanying drawings, details the method, apparatus, and terminal for simultaneous PUSCH transmission provided in this application, through some embodiments and application scenarios.

[0036] Please see Figure 2 The present application provides a method for simultaneous PUSCH transmission, the execution subject of which can be a terminal, such as... Figure 1 The terminal types listed in the illustrated embodiments may be any of the types listed, or may be any other than those listed below. Figure 1 Terminals other than those listed in the illustrated embodiments are not specifically limited here.

[0037] like Figure 2 As shown, the method for simultaneously sending the PUSCH may include the following steps:

[0038] Step 201: The terminal transmits the target PUSCH simultaneously through N antenna panels, wherein the target PUSCH is associated with N SRS resource sets, where N is an integer greater than 1, and the N SRS resource sets correspond one-to-one with the N antenna panels. The target transmission scheme adopted by the target PUSCH includes: frequency division multiplexing (FDM) transmission scheme, or single-frequency network (SFN) transmission scheme, or space division multiplexing (SDM) scheme.

[0039] In practice, N can be equal to 2 or any integer greater than 2. For ease of explanation, the following examples use N equal to 2 as an example, which does not constitute a specific limitation.

[0040] In practical applications, the terminal can simultaneously send the target PUSCH based on the N SRS resource sets associated with the target PUSCH. The specific transmission scheme, such as FDM, SFN, or SDM, can be determined based on the terminal's capabilities or by the network-side equipment.

[0041] The above N SRS resource sets correspond one-to-one with the N antenna panels. Each SRS resource set may include one or more SRS resources. All SRS resources in a given SRS resource set use the beam of the antenna panel corresponding to that SRS resource set. For example, if an SRS resource set includes multiple SRS resources, the multiple SRS resources may use different beams, and these different beams all belong to the antenna panel corresponding to that SRS resource set.

[0042] As an optional implementation, the method for simultaneous PUSCH transmission further includes:

[0043] The terminal sends capability information to the network-side device, wherein the capability information includes the PUSCH transmission scheme supported by the terminal.

[0044] The terminal determines the target transmission scheme based on the first indication information from the network-side device, wherein the PUSCH transmission scheme supported by the terminal includes the target transmission scheme.

[0045] In implementation, the terminal may support one or more of the FDM, SFN, and SDM transmission schemes. In this embodiment, the terminal can report the transmission scheme it supports or the identification information of the transmission scheme to the network-side device, so that the network-side device can select one of the transmission schemes supported by the terminal as the target transmission scheme for the target PUSCH, and send the selected target transmission scheme or the identification information of the target transmission scheme to the terminal, so that the terminal and the network-side device can reach an agreement on the transmission scheme adopted for the target PUSCH.

[0046] In implementation, the aforementioned first indication information can be carried in any message or signaling sent from the network-side device to the terminal. Optionally, the aforementioned first indication information can be reused from existing messages or signaling sent from the network-side device to the terminal. For example, when the first indication information is used to instruct the terminal to adopt a PDSCH simultaneous reception scheme, the terminal determines the target transmission scheme based on the first indication information from the network-side device, including:

[0047] The terminal determines that the target transmission scheme is the same as the transmission scheme corresponding to the PDSCH simultaneous reception scheme.

[0048] In this way, the terminal only needs to receive a first indication message from the network-side device to simultaneously determine the simultaneous reception scheme of PDSCH and the simultaneous transmission scheme of the target PUSCH, thereby saving signaling overhead.

[0049] Optionally, if the first indication information includes the number of demodulation reference signal DMRS code division multiplexing groups carried in the first downlink control information (DCI) signaling, and the first DCI signaling is used to schedule the target PUSCH, or if the first indication information includes the number of TBs configured for the target PUSCH, the terminal determines the target transmission scheme based on the first indication information from the network-side device, including at least one of the following:

[0050] If the number of DMRS CDM groups occupied by the target PUSCH or the number of configured TBs is greater than 1, the terminal determines that the target transmission scheme is an SDM transmission scheme.

[0051] If the number of DMRS CDM groups or the number of configured TBs occupied by the target PUSCH is equal to 1, the terminal determines that the target transmission scheme is an FDM transmission scheme or an SFN transmission scheme.

[0052] In this embodiment, the terminal can determine whether the target PUSCH transmission scheme is SDM or non-SDM based on the number of DMRS CDM groups occupied by the target PUSCH dynamically indicated in the first DCI signaling that schedules the target PUSCH, or based on the number of TBs configured by the higher layer for the target PUSCH.

[0053] Optionally, the number of repeated transmissions between time slots of the target PUSCH or the number of repeated transmissions on the nominal time dimension (which can also be called the nominal scale) is equal to 1.

[0054] In an embodiment, when the Time Domain Resource Allocation (TDRA) field in DCI format 0-1 or 0-2 indicates the number of times the PUSCH is repeatedly transmitted between time slots (when the PUSCH mapping type is configured as 'Type A' by network signaling) or the nominal number of times the PUSCH is repeated in the time dimension (when the PUSCH mapping type is configured as 'Type B' by network signaling) equals 1, the terminal selects one of the target transmission schemes to transmit the PUSCH; when the TDRA indicates a repetition count greater than 1, the terminal performs time-division PUSCH repetition transmission supported by Rel-17.

[0055] As an optional implementation, if the second DCI signaling for scheduling PDSCH indicates N transport configurations indicating TCI states, or if the second DCI signaling indicates N TCI state groups, then the N SRS resource sets correspond one-to-one with the N TCI states or N TCI state groups.

[0056] In implementation, the spatial relationship of one or more SRS resources in an SRS resource set is associated with the corresponding TCI state or TCI state group. Taking N=2 as an example, the spatial relationship of one or more SRS resources in the first SRS resource set can be associated with the first TCI state or first TCI state group indicated in the second DCI signaling; the spatial relationship of one or more SRS resources in the second SRS resource set can be associated with the second TCI state or second TCI state group indicated in the second DCI signaling.

[0057] In this way, the spatial relationship of SRS resources in the SRS resource set can be determined based on the correspondence between the SRS resource set and the TCI state or TCI state group.

[0058] In an optional implementation, when the target PUSCH adopts a codebook transmission mode, if the target SRS resource set in the N SRS resource sets includes M SRS resources, and the spatial relationship of the M SRS resources is associated with a TCI state indicated in the second DCI signaling, then the size of the SRS resource index indication field carried in the first DCI signaling that schedules the target PUSCH is related to the value of M, where M is an integer greater than or equal to 1.

[0059] In implementation, the size of the SRS resource index indicator field carried in the first DCI signaling of the target PUSCH mentioned above is related to the value of M. A larger value of M results in a larger SRS resource index indicator field, enabling it to indicate the indices of M SRS resources. For example, assuming the size of the SRS resource index indicator field is X bits, then... in, This indicates rounding down A. Thus, the SRS resource index indication field in the first DCI signaling can be used to indicate that the spatial relationships of M SRS resources are all associated with a TCI state indicated in the second DCI signaling.

[0060] Furthermore, when M is greater than 1, the number of ports corresponding to each SRS resource in the target SRS resource set is different. In this way, multiple SRS resources applied to the same TCI state can be transmitted using different numbers of ports, thereby enabling dynamic switching between full-power mode and non-full-power mode.

[0061] In another optional implementation, when the target PUSCH adopts a codebook transmission mode, if the target SRS resource set in the N SRS resource sets includes M SRS resources, and the spatial relationship of the M SRS resources is associated with a TCI state in a target TCI state group indicated in the second DCI signaling, then the size of the SRS resource index indication field carried in the first DCI signaling that schedules the target PUSCH is related to M', where M' represents the number of distinct SRS ports among the M SRS ports corresponding to the M SRS resources, and M' is an integer greater than or equal to 1 and less than or equal to M.

[0062] In implementation, the M SRS resources in the target SRS resource set mentioned above correspond to M SRS ports. These M SRS ports may include the same SRS ports. In this case, M' can be equal to the number of different types of SRS ports among the M SRS ports. For example, if M equals 4 and the SRS ports corresponding to these 4 SRS resources are 4, 4, 2, and 1 respectively, then M' equals 3.

[0063] The size of the SRS resource index indicator field carried in the first DCI signaling of the target PUSCH mentioned above is related to M'. A larger value for M' results in a larger SRS resource index indicator field, so that the SRS resource index indicator field can indicate the indices of M' SRS resources, each with a different SRS port. For example, assuming the size of the SRS resource index indicator field is X bits, then... In this way, the SRS resource corresponding to one of the SRS ports can be indicated by the SRS resource index indication field in the first DCI signaling.

[0064] Optionally, when the number of SRS resources corresponding to the target SRS port in the M SRS resources is L, the spatial relationship of the L SRS resources corresponding to the target SRS port is respectively associated with the first L TCI states in the target TCI state group, where L is an integer greater than 0.

[0065] In implementation, the target SRS port can be any SRS port corresponding to M SRS resources, and the target TCI state group can include K TCI states, where K can be an integer greater than or equal to L. When K equals L, the spatial relationship between the L TCI states and the L SRS resources corresponding to a certain SRS port can be determined based on all the TCI states in the target TCI state group. When K is greater than L, the first L TCI states are selected from the target TCI state group, and the spatial relationship between the L TCI states and the L SRS resources corresponding to a certain SRS port can be determined accordingly.

[0066] Optionally, the method for simultaneously sending PUSCH further includes:

[0067] The terminal determines, based on the first association relationship, that the SRS resource associated with the target PUSCH transmission includes: one of the L SRS resources corresponding to the target SRS port, and an SRS resource associated with the TCI status indicated in the second DCI signaling;

[0068] The first association relationship includes the spatial relationship between the L SRS resources corresponding to the target SRS port and the association relationship between the L TCI states.

[0069] Specifically, the first association relationship mentioned above refers to the association relationship in which the spatial relationship of the L SRS resources corresponding to the target SRS port is associated with the first L TCI states in the target TCI state group in a one-to-one correspondence.

[0070] For example, assuming N equals 4, where two SRS resources use SRS port A and the other two use SRS port B, if SRS port A corresponds to two unified beam resources, then based on a TCI state indicated in the downlink DCI, one of the two unified beam resources can be determined as an SRS resource associated with the target PUSCH transmission. That is, different SRS ports can be grouped and associated with the unified beam, and further, a TCI state indicated in the downlink DCI can be used to determine which unified beam will be associated with the target PUSCH transmission as an SRS resource.

[0071] In this embodiment, when at least two SRS resources correspond to a certain SRS port, the SRS resources associated with the target PUSCH transmission can be determined from the SRS resources corresponding to a certain SRS port by combining the SRS resources associated with the TCI state indicated in the second DCI signaling.

[0072] As an optional implementation, when N equals 2, the first DCI signaling that schedules the target PUSCH carries a first indication field and a second indication field;

[0073] When the target PUSCH adopts the codebook transmission mode, the first indication field includes a joint indication field of the transmit precoding matrix indicator (TPMI) and the rank indicator (RI) corresponding to the first SRS resource set, and the second indication field includes a TPMI indication field or a joint indication field of TPMI and RI corresponding to the second SRS resource set. The N SRS resource sets include the first SRS resource set and the second SRS resource set.

[0074] When the target PUSCH adopts a non-codebook transmission mode, the first indication field includes the joint indication field of SRS resource indication SRI and RI corresponding to the first SRS resource set, and the second indication field includes the SRI indication field or the joint indication field of SRI and RI corresponding to the second SRS resource set.

[0075] In this embodiment, two different indication fields are divided in the first DCI signaling to indicate the TPMI and RI of the first SRS resource set and the second SRS resource set respectively in codebook transmission mode; alternatively, two different indication fields are divided in the first DCI signaling to indicate the SRI and RI of the first SRS resource set and the second SRS resource set respectively in non-codebook transmission mode. It is worth noting that, in practice, only the RI of the first SRS resource set may be indicated, without indicating the RI of the second SRS resource set, and the RI of the second SRS resource set may be determined based on a preset rule according to the RI of the first SRS resource set. For example, the first indication field may contain the layer data stream number or RI information of the PUSCH transport resource associated with the first SRS resource set.

[0076] The number of layers or RI information of the PUSCH transport resources associated with the second SRS resource set is the same as the number of layers or RI information of the PUSCH transport resources associated with the first SRS resource set.

[0077] In codebook transmission mode, the first indication field can indicate the joint indication field of TPMI and RI corresponding to the first SRS resource set, while the second indication field only indicates the TPMI corresponding to the second SRS resource set. It is also determined that the number of layer data streams or RI information of the PUSCH transport resource associated with the second SRS resource set is the same as that of the PUSCH transport resource associated with the first SRS resource set. In non-codebook transmission mode, the first indication field can indicate the joint indication field of SRI and RI of the SRS resource indication corresponding to the first SRS resource set, while the second indication field only indicates the SRI corresponding to the second SRS resource set. It is also determined that the number of layer data streams or RI information of the PUSCH transport resource associated with the second SRS resource set is the same as that of the PUSCH transport resource associated with the first SRS resource set. This reduces the number of bits occupied by the second indication field.

[0078] Of course, both the first and second indication fields can indicate the joint indication field of TPMI and RI, or the joint indication field of SRI and RI, without specific limitations here.

[0079] As an optional implementation, the method for simultaneous PUSCH transmission further includes:

[0080] The terminal receives first configuration information;

[0081] Wherein, the first configuration information is used to configure a first maximum rank and a second maximum rank, wherein the first maximum rank is the maximum rank supported by the first indicator domain, and the second maximum rank is the maximum rank supported by the second indicator domain; or...

[0082] The first configuration information is used to configure the third rank maximum value, which is the maximum rank value supported by the first indication domain.

[0083] In practice, the aforementioned first configuration information may be configuration information for the target PUSCH transmission to configure the maximum rank.

[0084] In one optional implementation, the first rank maximum value is the maximum rank value supported by the first indicator field. This can be understood as follows: assuming the first rank maximum value is 4, the first indicator field can be used to indicate any rank among 1, 2, 3, and 4. Similarly, the rank value indicated by the second indicator field can be less than or equal to the second rank maximum value. Thus, the two rank maximum values ​​respectively indicate the maximum number of ranks allowed to be indicated by the first and second indicator fields.

[0085] In another optional implementation, the first configuration information is only used to configure the maximum rank value supported by the first indication domain, while the maximum rank value supported by the second indication domain can be determined according to the maximum rank value supported by the first indication domain using preset rules.

[0086] For example, when the first configuration information is used to configure the maximum value of the third rank, the maximum rank value R′ supported by the second indication field may include any of the following:

[0087] Among them, R max This represents the maximum value of the third rank. This indicates rounding down A;

[0088] in, This means rounding A up;

[0089] R′=R max .

[0090] Thus, compared to the implementation that separately indicates the maximum rank allowed to be indicated in the first and second indication fields, the implementation that only indicates the third maximum rank of the first indication field and calculates the maximum rank supported by the second indication field based on the third maximum rank using a preset rule can reduce the amount of information in the first configuration information. In implementation, the specific preset rule used to determine the maximum rank supported by the second indication field can be agreed upon in the protocol or pre-configured, and is not specifically limited here.

[0091] In this embodiment, when two TPMI fields or SRI fields are carried in the first DCI signaling, it is supported that the ranks associated with different SRIs can be indicated separately or shared.

[0092] As an optional implementation, the first DCI signaling further includes second indication information, which indicates that at least one of the following rules is in effect:

[0093] The first indication field is associated with the first SRS resource set among the N SRS resource sets, and the second indication field is associated with the second SRS resource set among the N SRS resource sets;

[0094] The first indication field is associated with the second SRS resource set among the N SRS resource sets, and the second indication field is associated with the first SRS resource set among the N SRS resource sets.

[0095] In implementation, the second indication information can dynamically switch the association between the first and second indication domains and the first SRS resource set, respectively. In implementation, the second indication information can reuse the indication information used in related technologies to indicate beam switching. For example, in related technologies, assuming the second indication information is 10, it indicates that the first SRS resource set corresponds to beam1 and the second SRS resource set corresponds to beam2; assuming the second indication information is 11, it indicates that the second SRS resource set corresponds to beam1 and the first SRS resource set corresponds to beam2. In this embodiment, when the target PUSCH is transmitted simultaneously on N antenna panels, the beam scheme is the same when the second indication information is 10 and the second indication information is 11. In this embodiment, the second indication information can be reused to indicate the switching between the above two rules.

[0096] As an optional implementation, when N equals 2 and the target transmission scheme is an FDM transmission scheme, the sum of the number of the first physical resource blocks (PRBs) and the number of the second PRBs is equal to the number of PRBs occupied by the target PUSCH as indicated by the frequency domain resource allocation (FDRA) field in the first DCI signaling.

[0097] Wherein, the first PRB number is the number of first PRBs occupied by the PUSCH transmission resources associated with the first SRS resource set among the N SRS resource sets;

[0098] The second PRB number is the number of second PRBs occupied by the PUSCH transmission resources associated with the second SRS resource set among the N SRS resource sets;

[0099] The first DCI signaling is used to schedule the target PUSCH.

[0100] In this embodiment, when the target PUSCH is associated with two SRS resource sets, each of the two SRS resource sets occupies its own PRB, and the sum of the number of PRBs occupied by the two SRS resource sets is equal to the number of PRBs occupied by the target PUSCH as indicated by the FDRA field.

[0101] In implementation, if the target PUSCH occupied by the FDRA field indicates the number N of PRBs... PRB If it is not divisible by N, then the first and second PRB numbers can be determined in the following way:

[0102] Method 1: The first PRB number equals The second PRB number equals

[0103] Method 2: The first PRB number equals The second PRB number equals

[0104] In practice, the first PRB number and the second PRB number can be determined by default using either method one or method two.

[0105] Furthermore, the starting frequency domain position of the first PRB can be the first PRB position from the lowest frequency on the frequency domain resources occupied by the target PUSCH indicated by the FDRA domain. When the frequency domain frequency hopping function is enabled, the low-frequency position before frequency hopping can be used as the starting frequency domain position of the first PRB. In other words, the first PRB is a continuous frequency domain position including the lowest frequency position in the frequency domain resources occupied by the target PUSCH.

[0106] Correspondingly, the frequency domain position of the second PRB can be a continuous frequency domain configuration at the other end of the frequency domain resources occupied by the target PUSCH, excluding the frequency domain position where the first PRB is located. This ensures that the frequency domain resources of both the first and second PRBs are continuous. Furthermore, when frequency hopping mode is enabled, the result after frequency hopping can also be that the first and second PRBs occupy consecutive frequency domain PRBs. However, the first and second PRBs can be discontinuous in the frequency domain.

[0107] In this embodiment, when the target PUSCH is configured as a DFT waveform, considering the scheduling restrictions of the target PUSCH on the PRB under the FDM transmission scheme, and considering the impact when frequency hopping is enabled, it can support the target PUSCH to be transmitted according to the DFT waveform under the FDM transmission scheme in the frequency hopping enabled mode.

[0108] Optionally, the transfer data block size (TB) of the target PUSCH is determined based on any of the following reference PRB numbers:

[0109] Equal to the N PRB ;

[0110] equal

[0111] It is equal to the first PRB number.

[0112] Option 1, for the target PUSCH, the transfer data block size (TB) is referenced to N. PRB In certain cases, it can be based on setting the reference PRB to N. PRB The value of the reference PRB is then substituted into the formula for calculating the TB size of the target PUSCH transmission data block to obtain the TB size of the target PUSCH. This is similar to the FDM-A scheme that simultaneously receives PDSCH in related technologies, and will not be described in detail here.

[0113] Option 2, refer to the TB size of the transmission data block for the target PUSCH. The situation is similar to the FDM-B scheme that simultaneously receives PDSCH in related technologies, and will not be elaborated further here.

[0114] Option 3, for the case where the size of the target PUSCH's transmitted data block (TB) is determined by referring to the first PRB, the first PRB number may be equal to... It may also equal to The first PRB number may equal When option three is the same as option two, in the first PRB equals At that time, the number of PRBs occupied by the first PRB is still used as the basis to determine the size of the transmission data block TB of the target PUSCH.

[0115] As an optional implementation, when the waveform of the target PUSCH is a Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform, the first PRB number and the second PRB number respectively satisfy the target constraint conditions, wherein the target constraint conditions include: equal to 2. x *3 y *5 z x, y, and z are integers greater than or equal to 0.

[0116] In this embodiment, by ensuring that the number of the first PRB and the number of the second PRB satisfy the target constraint conditions respectively, it is possible to support the use of DFT to perform Fourier transforms on the first PRB and the second PRB related to the DFT-s-OFDM waveform.

[0117] As an optional implementation, when the waveform of the target PUSCH is a DFT-s-OFDM waveform, the method further includes:

[0118] The terminal generates a first ZC sequence corresponding to the first PRB number and a second ZC sequence corresponding to the second PRB number. The first ZC sequence and the second ZC sequence are used to generate DMRS.

[0119] In this embodiment, the terminal generates two ZC sequences corresponding to the first PRB number and the second PRB number, respectively. The ZC sequence corresponding to the first PRB number is used for the DMRS corresponding to the first PRB, and the ZC sequence corresponding to the second PRB number is used for the DMRS corresponding to the second PRB. Thus, two DMRSs can be used to support the demodulation of DFT-s-OFDM waveform signals transmitted on the first and second PRBs.

[0120] As an optional implementation, when the target transmission scheme is an FDM transmission scheme and the waveform of the target PUSCH is a DFT-s-OFDM waveform, the first phase-tracking reference signal (PTRS) is associated with the SRS resources in the first SRS resource set, and the second PTRS is associated with the SRS resources in the second SRS resource set.

[0121] In this embodiment, the PTRS and the SRS resources in the associated SRS resource set can use the same beam information method for transmission.

[0122] Optionally, the number of PTRS groups in the first PTRS and / or the number of PTRS samples in each PTRS group are related to the number of the first PRBs;

[0123] The number of PTRS groups in the second PTRS and / or the number of PTRS samples within each PTRS group are related to the number of the second PRB.

[0124] In implementation, the number of PTRS groups and / or the number of PTRS samples within each PTRS group are related to the number of PRBs. This can be achieved by dividing the PRBs into multiple value intervals, each interval having its own corresponding number of PTRS groups and / or the number of PTRS samples within each PTRS group. In this way, the value interval to which the PRBs belong can be determined based on the PRBs, and the number of PTRS groups and / or the number of PTRS samples within each PTRS group corresponding to that value interval can be determined.

[0125] In this embodiment, the number of PTRS groups of the first PTRS associated with the SRS resources in the first SRS resource set and the number of PTRS samples in each PTRS group can be determined based on the first PRB number, and the number of PTRS groups of the second PTRS associated with the SRS resources in the second SRS resource set and the number of PTRS samples in each PTRS group can be determined based on the second PRB number.

[0126] Furthermore, the number of PTRS groups in the first PTRS is the same as the number of PTRS groups in the second PTRS, and the number of PTRS samples in each PTRS group of the first PTRS is the same as the number of PTRS samples in each PTRS group of the second PTRS.

[0127] The number of PTRS groups in the first PTRS, the number of PTRS groups in the second PTRS, the number of PTRS samples in each PTRS group of the first PTRS, and the number of PTRS samples in each PTRS group of the second PTRS are related to the preset number of PRBs in the first number of PRBs and the second number of PRBs.

[0128] In practice, the aforementioned preset PRB number can be either the first PRB number or the second PRB number. For example, the first PRB number, or a PRB number determined based on the values ​​of the first PRB number and the second PRB number. For example, the preset PRB number is the largest value among the first PRB number and the second PRB number, or the preset PRB number is the smallest value among the first PRB number and the second PRB number. No specific limitation is made here.

[0129] In this embodiment, the first PTRS and the second PTRS have the same number of PTRS groups, and the number of PTRS samples in each PTRS group is the same. Thus, it is only necessary to determine the number of PTRS groups and the number of PTRS samples in each PTRS group according to the first PRB number or the second PRB number.

[0130] As an optional implementation, when the target PUSCH includes a first PUSCH transmission timing and a second PUSCH transmission timing, the first PUSCH transmission timing is transmitted on the first PRB, and the second PUSCH transmission timing is transmitted on the second PRB.

[0131] In implementation, the target PUSCH mentioned above includes a first PUSCH transmission timing and a second PUSCH transmission timing. The target PUSCH may adopt a scheme similar to the FDM-B transmission scheme in the PDSCH simultaneous reception scheme in related technologies, and the data transmitted on the target PUSCH may be copied into two copies with different RV redundancy versions, so as to be sent to the network-side device at the first PUSCH transmission timing and the second PUSCH transmission timing respectively.

[0132] In this embodiment, the two PUSCHs included in the target PUSCH can each occupy a different PRB for transmission.

[0133] In one optional implementation, the data transmitted by the target PUSCH and the Channel State Information (CSI) report information are multiplexed and transmitted using at least one of the following methods:

[0134] The CSI report information is multiplexed and transmitted according to the size of the first PRB and the timing of the first PUSCH transmission, and the CSI report information is also multiplexed and transmitted according to the size of the second PRB and the timing of the second PUSCH transmission.

[0135] The CSI report information is multiplexed with the first PUSCH transmission timing and the second PUSCH transmission timing, respectively, according to the size of the first PRB or the size of the second PRB.

[0136] The CSI report information is multiplexed and transmitted with the first PUSCH transmission timing and the second PUSCH transmission timing, respectively, based on the minimum value of the size of the first PRB or the size of the second PRB.

[0137] The CSI report information is multiplexed and transmitted with the first PUSCH transmission timing and the second PUSCH transmission timing, respectively, based on the maximum value of the first PRB size or the second PRB size.

[0138] The CSI report information is multiplexed with the target PUSCH based on the size of the PRB occupied by the target PUSCH.

[0139] Option 1: For the case where the CSI report information is multiplexed with the first PUSCH transmission timing based on the size of the first PRB, and the CSI report information is also multiplexed with the second PUSCH transmission timing based on the size of the second PRB, i.e., the same CSI report information is independently multiplexed with the first PUSCH transmission timing and the second PUSCH transmission timing according to existing behaviors. The multiplexing method includes CSI rate matching behavior and PUSCH rate matching behavior, wherein the CSI rate matching behavior and PUSCH rate matching behavior are respectively related to their corresponding PRB numbers, so that the CSI report information and the data carried on the PUSCH can be blended according to a certain order and rules based on the PRB number.

[0140] Option 2: For the CSI report information, the transmission is multiplexed with the first PUSCH transmission timing and the second PUSCH transmission timing according to the size of the first PRB or the size of the second PRB, respectively. The difference from Option 1 is that the CSI report information is combined with the data transmitted on the first PUSCH transmission timing and the second PUSCH transmission timing according to the multiplexing method corresponding to either the number of first PRBs or the number of second PRBs.

[0141] Option 3: For the CSI report information, based on the minimum value of the first PRB size or the second PRB size, it is multiplexed with the first PUSCH transmission timing and the second PUSCH transmission timing, respectively. The difference from Option 2 is that the CSI report information is combined with the data transmitted on the first PUSCH transmission timing and the second PUSCH transmission timing according to the multiplexing method corresponding to the minimum value of the first PRB number and the second PRB number.

[0142] Option 4: The CSI report information is multiplexed with the first PUSCH transmission timing and the second PUSCH transmission timing according to the maximum value of the first PRB size or the second PRB size. The difference from Option 2 is that the CSI report information is combined with the data transmitted on the first PUSCH transmission timing and the second PUSCH transmission timing according to the multiplexing method corresponding to the maximum value of the first PRB size and the second PRB size.

[0143] Option 5: Regarding the CSI report information based on the size of the PRBs occupied by the target PUSCH and the multiplexing transmission of the target PUSCH, the difference from Option 2 is that it is based on the sum of the first PRB number and the second PRB number (i.e., the total number of PRBs N occupied by the target PUSCH). PRBThe corresponding multiplexing method integrates the data transmitted on the target PUSCH as a whole with the CSI report information.

[0144] In this embodiment, CSI reporting information can be multiplexed and transmitted with data transmitted on the target PUSCH in various multiplexing methods.

[0145] In another optional implementation, when the third DCI signaling uses DCI format 2_4 and the third DCI signaling carries an uplink PUSCH cancellation command, the method further includes:

[0146] The terminal cancels the transmission of at least one of the first PUSCH transmission timing and the second PUSCH transmission timing according to the uplink PUSCH cancellation command.

[0147] In implementation, the third DCI signaling of the aforementioned DCI format 2_4 is used to instruct the terminal to cancel the transmission of PUSCH at a future time. In this embodiment, the terminal can cancel the transmission of at least one of the first PUSCH transmission timing and the second PUSCH transmission timing based on receiving the third DCI signaling. Specifically, the terminal can determine which of the first and second PUSCH transmission timings to cancel, or both, can be canceled using the following methods:

[0148] Optionally, the terminal cancels the transmission of at least one of the first PUSCH transmission timing and the second PUSCH transmission timing, including at least one of the following:

[0149] If the terminal determines that the frequency domain resource indicated for cancellation in the third DCI signaling overlaps at least partially with the frequency domain resource of the first PRB and does not overlap with the frequency domain resource of the second PRB, it cancels the transmission of the first PUSCH transmission timing.

[0150] If the terminal determines that the frequency domain resource indicated for cancellation in the third DCI signaling overlaps at least partially with the frequency domain resource of the second PRB and does not overlap with the frequency domain resource of the first PRB, it cancels the transmission of the second PUSCH transmission timing.

[0151] If the terminal determines that the frequency domain resources indicated for cancellation in the third DCI signaling at least partially overlap with the frequency domain resources of the first PRB and the second PRB, it cancels the transmission of the first PUSCH transmission timing and the second PUSCH transmission timing.

[0152] In this embodiment, the terminal cancels the transmission of the PUSCH corresponding to the PRB whose frequency domain resources at least partially overlap with those indicated for cancellation in the third DCI signaling, thereby realizing the cancellation behavior at the antenna panel level.

[0153] As an optional implementation, when N equals 2, the method further includes:

[0154] The terminal acquires third indication information, which is carried in first DCI signaling. The first DCI signaling is used to schedule the target PUSCH. The third indication information is used to indicate that at least one of the following rules is in effect:

[0155] The PUSCH transport resource associated with the first SRS resource set among the N SRS resource sets uses the DMRS port of the first CDM group among the two CDM groups, and the PUSCH transport resource associated with the second SRS resource set among the N SRS resource sets uses the DMRS port of the second CDM group among the two CDM groups.

[0156] The PUSCH transport resource associated with the first SRS resource set uses the DMRS port of the second CDM group of the two CDM groups, and the PUSCH transport resource associated with the second SRS resource set uses the DMRS port of the first CDM group of the two CDM groups.

[0157] The PUSCH transport resources associated with the first SRS resource set or the second SRS resource set use the DMRS ports of the two CDM groups;

[0158] The first PTRS domain is associated with at least one DMRS port used by the PUSCH transmission resource of the first SRS resource set in the N SRS resource sets, and the second PTRS domain is associated with at least one DMRS port used by the PUSCH transmission resource of the second SRS resource set in the N SRS resource sets.

[0159] The first PTRS domain is associated with at least one DMRS port used by the PUSCH transport resource of the second SRS resource set, and the second PTRS domain is associated with at least one DMRS port used by the PUSCH transport resource of the first SRS resource set.

[0160] In implementation, the DMRS port information of the target PUSCH can occupy two CDM groups, that is, the target PUSCH can adopt the SDM transmission scheme. Of course, in implementation, the target PUSCH can also adopt other schemes, such as the SFN transmission scheme or the FDM transmission scheme, etc., which will not be specifically mentioned here.

[0161] Rule 1: The PUSCH transmission resource associated with the first SRS resource set among the N SRS resource sets uses the DMRS port of the first CDM group among the two CDM groups, and the PUSCH transmission resource associated with the second SRS resource set among the N SRS resource sets uses the DMRS port of the second CDM group among the two CDM groups. This can be achieved by associating the PUSCH transmission resources associated with the N SRS resource sets with the DMRS ports of the N CDM groups in a one-to-one correspondence. In this way, when the target PUSCH is transmitted simultaneously through the first antenna panel and the second antenna panel, each antenna panel can occupy the DMRS port associated with its corresponding SRS resource set.

[0162] Rule 2: The PUSCH transmission resources associated with the first SRS resource set use the DMRS port of the second CDM group among the two CDM groups, and the PUSCH transmission resources associated with the second SRS resource set use the DMRS port of the first CDM group among the two CDM groups. The difference from Rule 1 is that the association between the PUSCH transmission resources associated with N SRS resource sets and the DMRS ports of the N CDM groups can be switched.

[0163] Rule 3: PUSCH transmission resources associated with the first SRS resource set or the second SRS resource set use the DMRS ports of the two CDM groups. This differs from Rules 1 and 2 in that, at certain times, the target PUSCH may also support transmission on only one antenna panel, in which case that antenna panel may occupy one or more DMRS ports.

[0164] Rule 4: The first PTRS domain is associated with at least one DMRS port used by the PUSCH transmission resource of the first SRS resource set among the N SRS resource sets, and the second PTRS domain is associated with at least one DMRS port used by the PUSCH transmission resource of the second SRS resource set among the N SRS resource sets. In implementation, each SRS resource set associated with a PUSCH transmission resource may use one or more DMRS ports, wherein the PTRS occupies at least one DMRS port.

[0165] Through rule four above, the signaling can instruct the terminal to associate the PTRS domains of N antenna panels with N SRS resource sets in a one-to-one correspondence, thereby enabling the PTRS domains to use the PUSCH transmission resources of the associated SRS resource sets to transmit DMRS ports.

[0166] Rule 5: The first PTRS domain is associated with at least one DMRS port used by the PUSCH transmission resources of the second SRS resource set, and the second PTRS domain is associated with at least one DMRS port used by the PUSCH transmission resources of the first SRS resource set. This rule differs from Rule 4 above in that the association between the PTRS domains of the N antenna panels and the N SRS resource sets can be switched.

[0167] In this embodiment, by carrying the aforementioned third instruction information in the first signaling, the terminal can be instructed to adopt any one of the aforementioned rules one to five, thereby realizing the flexible switching of the aforementioned rules one to five.

[0168] As an optional implementation, when the target transmission scheme is the SFN transmission scheme, if the target PUSCH is configured with a first PTRS port and a second PTRS port, then the first PTRS port corresponds to a different DMRS port, wherein the different DMRS ports belong to different CDM groups.

[0169] In the SFN transmission scheme, the same data is transmitted on the PUSCH resources associated with N SRS resource sets. However, the PUSCH resources associated with N SRS resource sets can use different DMRS pilots (corresponding to different DMRS ports). In this embodiment, by configuring two different PTRS ports for the target PUSCH, and each PTRS port corresponds to a different DMRS port in a different CDM group, the PUSCH resources associated with N SRS resource sets can use different DMRS pilots.

[0170] As an optional implementation, when the target transmission scheme is the SFN transmission scheme, if the waveform of the target PUSCH is the CP-OFDM waveform, then the first offset value is the value corresponding to the resource element offset indicated by the higher layer signaling, or the first offset value is the value corresponding to the default first resource element offset.

[0171] Wherein, the first offset value is the frequency domain offset of the PTRS on the PUSCH transport resource associated with the first SRS resource set among the N SRS resource sets.

[0172] In practice, the value of resourceElementOffset can be any one of Offse00, Offse01, Offse10, and Offse11. If the higher-level signaling specifies a value for resourceElementOffset, that value will prevail. If the higher-level signaling does not specify a value for resourceElementOffset, the default first resource element offset will be used. For example, the default first resource element offset is equal to Offse00.

[0173] Through this implementation method, the frequency domain offset value of the PTRS on the PUSCH transmission resource associated with the first SRS resource set among the N SRS resource sets can be determined.

[0174] Optionally, if the target transmission scheme is the SFN transmission scheme, and the waveform of the target PUSCH is the CP-OFDM waveform, then the second offset value is an offset value related to the first offset value, or the second offset value is the value corresponding to the default second resource element offset.

[0175] Wherein, the second offset value is the frequency domain offset of the PTRS on the PUSCH transport resource associated with the second SRS resource set among the N SRS resource sets.

[0176] In implementation, the offset value related to the first offset value can be: the second offset value is calculated based on the first offset value using a preset calculation rule. For example, assuming the first offset value is V1 and the second offset value is V2, the second offset value can be calculated according to the formula V2 = (V1 + h) mod 12, where h is an integer. This can reduce the mutual interference of PTRS on the PUSCH transmission resources of the N SRS resource sets.

[0177] Of course, in practice, the second offset value can also be directly set to the value corresponding to the offset of the second resource element, for example: the offset of the second resource element is set to Offse01 by default.

[0178] For example, if the higher-level signaling indicates the value corresponding to resourceElementOffset, the first offset value V1 can be determined based on the value corresponding to resourceElementOffset, and the second offset value can be calculated based on the formula V2=(V1+h)mod 12; if the higher-level signaling does not indicate the value corresponding to resourceElementOffset, the first offset value can be assumed to be equal to the value corresponding to Offse00, and the second offset value can be assumed to be equal to the value corresponding to Offse01.

[0179] During PUSCH transmission, the terminal can perform rate matching on the PTRS of the two associated SRS resources based on the first offset value and the second offset value mentioned above.

[0180] As an optional implementation, if the target transmission scheme is an SFN transmission scheme, and the waveform of the target PUSCH is a DFT-s-OFDM waveform:

[0181] The index value of the orthogonal sequence used by PTRS on the PUSCH transport resource of the first SRS resource set in the N SRS resource sets is determined based on the following formula:

[0182]

[0183] in, This represents the number of orthogonal sequences within the PTRS group to which the PTRS belongs (e.g.: (equal to 2 or 4), n RNTI This represents the number of RNTIs associated with the scrambling of the first DCI signaling transmitted to the target PUSCH, or a constant value associated with the RNTI scrambling value of the first DCI signaling, or a default constant.

[0184] And / or,

[0185] The index value of the orthogonal sequence used by PTRS on the PUSCH transport resources of the second SRS resource set in the N SRS resource sets is determined based on the following formula:

[0186]

[0187] Where k is a positive integer.

[0188] In implementation, the value of k can be a fixed integer (e.g., k = 1), or the value of k can be flexibly configured through the protocol, without specific limitations here.

[0189] In this embodiment, the RNTI number related to the scrambling of the first DCI signaling or a constant value n related to the RNTI scrambling value of the first DCI signaling can be configured. RNTI This is used to determine the index value of the orthogonal sequence used by PTRS on the PUSCH transport resources corresponding to each of the N SRS resource sets. This reduces mutual interference between PTRS on the PUSCH transport resources of the N SRS resource sets.

[0190] As an optional implementation, when N equals 2 and the first DCI signaling that schedules the target PUSCH is configured with two TB associated fields, if the target PUSCH is used to transmit two TBs simultaneously, then the first PTRS is associated with the SRS resources in the first SRS resource set, and the second PTRS is associated with the SRS resources in the second SRS resource set.

[0191] The N SRS resource sets include the first SRS resource set and the second SRS resource set.

[0192] In this embodiment, the PUSCH transmission resources corresponding to the two SRS resource sets are used to transmit their respective TB blocks. Thus, the SRS resources in the two SRS resource sets have their own associated PTRS. In this way, two TB blocks can be transmitted simultaneously based on different PTRS.

[0193] Optionally, if two TB indications are configured in the first DCI signaling;

[0194] The density of the first PTRS is related to the modulation and coding scheme (MCS) level used by the first TB indicated by the two TB indicators, and the density of the second PTRS is related to the MCS level used by the second TB indicated by the two TB indicators; or,

[0195] The density of the first PTRS is the same as that of the second PTRS, and is related to the MCS level used by the preset TB indicated by the two TB indicators.

[0196] In one alternative implementation, the density of the first PTRS and the density of the second PTRS correspond one-to-one with the MCS level used by the first TB and the MCS level used by the second TB, respectively.

[0197] In another optional implementation, the density of the first PTRS is the same as that of the second PTRS, and corresponds to the MCS level used by the preset TB. The preset TB can be the TB at the preset position indicated by the two TB indicators (e.g., the TB in the first position or the TB in the second position), or the TB with the largest MCS among the first and second TBs indicated by the two TB indicators, or the TB with the smallest MCS among the first and second TBs indicated by the two TB indicators. No specific limitation is made here.

[0198] In this embodiment, the density of the first PTRS and the density of the second PTRS can be determined based on at least one of the MCS levels used by the two TB indications configured in the first DCI signaling.

[0199] In this embodiment, the terminal simultaneously transmits a target PUSCH through N antenna panels. Each target PUSCH is associated with N SRS resource sets, where N is an integer greater than 1. Each of the N SRS resource sets corresponds one-to-one with one of the N antenna panels. The target PUSCH uses a target transmission scheme including: Frequency Division Multiplexing (FDM), Single Frequency Network (SFN), or Space Division Multiplexing (SDM). This allows the terminal to simultaneously transmit the target PUSCH using at least two antenna panels, improving the transmission efficiency of the target PUSCH.

[0200] The method for simultaneous PUSCH transmission provided in this application can be executed by a device for simultaneous PUSCH transmission. This application uses an example of a device for simultaneous PUSCH transmission executing the method to illustrate the device for simultaneous PUSCH transmission provided in this application.

[0201] Please see Figure 3 This application provides an apparatus for simultaneous PUSCH transmission, which can be applied to terminals, such as... Figure 3 As shown, the device 300 that transmits PUSCH simultaneously may include the following modules:

[0202] The transmission module 301 is used to transmit a target PUSCH simultaneously through N antenna panels, wherein the target PUSCH is associated with N SRS resource sets, N is an integer greater than 1, the N SRS resource sets correspond one-to-one with the N antenna panels, and the target transmission scheme adopted by the target PUSCH includes: frequency division multiplexing (FDM) transmission scheme, or single-frequency network (SFN) transmission scheme, or space division multiplexing (SDM) scheme.

[0203] Optionally, the device 300 for simultaneous PUSCH transmission also includes:

[0204] A sending module is used to send capability information to network-side devices, wherein the capability information includes the PUSCH transmission scheme supported by the terminal;

[0205] The first determining module is configured to determine the target transmission scheme based on first indication information from the network-side device, wherein the PUSCH transmission scheme supported by the terminal includes the target transmission scheme.

[0206] Optionally, when the first indication information is used to instruct the terminal to adopt a Physical Downlink Shared Channel (PDSCH) simultaneous reception scheme, the first determining module is specifically used for:

[0207] The target transmission scheme is determined to be the same as the transmission scheme corresponding to the PDSCH simultaneous reception scheme.

[0208] Optionally, if the first indication information includes the number of Demodulation Reference Signal (DMRS) Code Division Multiplexing (CDM) groups used to indicate the number of occupied groups carried in the first downlink control information (DCI) signaling for scheduling the target PUSCH, or if the first indication information includes the number of transport blocks (TBs) configured for the target PUSCH, the first determining module is specifically configured to perform at least one of the following:

[0209] If the number of DMRS CDM groups occupied by the target PUSCH or the number of configured TBs is greater than 1, the target transmission scheme is determined to be an SDM transmission scheme.

[0210] If the number of DMRS CDM groups occupied by the target PUSCH or the number of configured TBs is equal to 1, the target transmission scheme is determined to be either an FDM transmission scheme or an SFN transmission scheme.

[0211] Optionally, the number of times the target PUSCH is repeatedly transmitted between time slots or the nominal number of times it is repeatedly transmitted in the time dimension is equal to 1.

[0212] Optionally, if the second DCI signaling for scheduling PDSCH indicates N transport configurations indicating TCI states, or if the second DCI signaling indicates N TCI state groups, then the N SRS resource sets correspond one-to-one with the N TCI states or N TCI state groups.
