With the introduction of simultaneous transmission of multiple TRPs / panels / beams, there is currently no clear method for how terminal devices determine the number of bits in the relevant information field based on the different maximum transmission layer counts.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0034] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0035] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto.

[0036] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110.

[0046] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0047] The transmission of the physical downlink shared channel (PUSCH) may include codebook-based transmission and non-codebook-based transmission. The codebook-based transmission scheme of PUSCH may include the following steps:

[0048] Step 1: The terminal device sends a sounding reference signal (SRS) for a codebook to the network device.

[0049] Step 2: The network device performs uplink channel detection based on the SRS sent by the terminal device, schedules resources for the terminal device, and determines the SRS resources corresponding to the PUSCH transmission, the number of uplink transmission layers, and the precoding matrix. The network device indicates this information to the terminal device via downlink control information (DCI).

[0050] Step 3: The terminal device receives the DCI and sends the PUSCH according to the instructions of the DCI.

[0051] In the codebook-based PUSCH transmission scheme, the network device can indicate the number of uplink transmission layers and precoding matrix of the PUSCH through the Transmitted Precoding Matrix Indicator (TPMI) field in the DCI. The specific SRS resources in the SRS resource set are indicated through the SRS Resource Indicator (SRI) field in the DCI. The number of PUSCH transmission layers and the PUSCH precoding matrix are indicated using a joint coding method.

[0052] It should be noted that for the codebook-based PUSCH transmission scheme, the terminal device can determine the number of bits in the TPMI field based on the configured maximum number of transmission layers (also known as the maximum rank), that is, the value of the configured high-level parameter maxRank / maxMIMO-Layers. In this way, the terminal device can obtain the value range of the TPMI field based on the determined number of bits, thereby determining the precoding matrix actually indicated by the TPMI field to complete PUSCH transmission.

[0053] In addition, non-codebook based transmission of the PUSCH may include the following steps:

[0054] Step 1: The terminal device measures the downlink reference signal, obtains a candidate precoding matrix, precodes the SRS using the candidate precoding matrix, and then sends the SRS for non-codebook to the network device.

[0055] Step 2: The network device performs uplink channel detection based on the SRS sent by the terminal device, schedules resources for the terminal device, and determines the SRS resources corresponding to the beam transmitted by the PUSCH; the network device indicates the above information to the terminal device through the DCI.

[0056] Step 3: The terminal device receives the DCI and transmits the PUSCH according to the instructions of the DCI.

[0057] In non-codebook-based PUSCH transmission schemes, the network device indicates the number of PUSCH transmission layers and the SRS resources in the SRS resource set to the terminal device via the SRI field in the DCI. For non-codebook-based PUSCH transmission schemes, the terminal device can determine the number of SRI bits based on the configured maximum number of transmission layers, namely the network-configured high-layer parameters maxRank / maxMIMO-Layers. This number of bits can be used by the terminal device to determine the range of the SRI field and thus the SRS resource set actually indicated by the SRI field.

[0058] To improve uplink transmission reliability, Release 17 (R17) of the standardization process introduced two PUSCH transmission schemes: TRP / panel / beam. For the codebook-based PUSCH transmission scheme, the PUSCH repetition types include repetition type A and repetition type B.

[0059] Since the number of transmission layers of PUSCH repetition type A is limited to 1, there is no need to additionally indicate the association relationship between the Phase Tracking Reference Signals (PTRS) port and the Dedicated Demodulation Reference Signals (DMRS) port.

[0060] For PUSCH repetition type B, the number of transmission layers can be greater than one. When maxrank is 2 (i.e., the maximum number of transmission layers is 2), only one PTRS port is required. DCI formats 0-1 or 0-2 use 2 bits to indicate the association between the PTRS port and the DMRS port. As shown in Table 1, the 2 bits can include the most significant bit (MSB) and the least significant bit (LSB), corresponding to TRP1 and TRP2, respectively.

[0061] Table 1

[0062]

[0063] As can be seen from Table 1, the state of 0 in the MSB can be used to indicate that the PTRS of the PUSCH sent to TRP1 is associated with the first DMRS port. The state of 1 in the MSB can be used to indicate that the PTRS of the PUSCH sent to TRP1 is associated with the second DMRS port. The state of 0 in the LSB can be used to indicate that the PT-RS of the PUSCH sent to TRP2 is associated with the first DMRS port. The state of 1 in the LSB can be used to indicate that the PT-RS of the PUSCH sent to TRP2 is associated with the second DMRS port.

[0064] When maxrank is greater than 2 (i.e., the maximum number of transmission layers is greater than 2), the actual need for one or two PTRS ports is determined based on the TPMI and the number of transmission layers. DCI format 0-1 or DCI format 0-2 uses 4 bits to indicate the association between the PTRS port and the DMRS port.

[0065] In some embodiments, when the actual number of PTRS ports is determined to be 1 according to the TPMI and the number of transport layers, the DMRS port associated with the PTRS port may be determined according to Table 2.

[0066] Table 2

[0067] Status value DMRS port 0 1st DMRS port 1 2nd DMRS port 2 3rd DMRS port 3 4th DMRS port

[0068] In other embodiments, when the actual number of PTRS ports is determined to be 2 based on the TPMI and the number of transport layers, the DMRS port associated with each PTRS port can be determined based on Table 3. The MSB and LSB are associated with different TRPs, respectively, and the DMRS port associated with the PTRS is determined based on the status of the MSB and LSB.

[0069] Table 3

[0070]

[0071] In actual applications, the terminal device is usually configured with a maximum number of transmission layers (i.e., a maxRank). The terminal device can determine the number of bits of the indication field related to the PUSCH transmission parameters and the specific indication information based on the maxRank. For example, the terminal device can determine the number of bits of the PTRS-DMRS association indication (PTRS-DMRS association) field and the specific association relationship table based on the maxRank.

[0072] The current communication system does not support configuring different maximum transmission layers for multiple panels. However, in the scenario of simultaneous transmission of multiple TRP / panel / beam, different panels may have different maximum transmission layers. After the introduction of the scheme of simultaneous transmission of multiple TRP / panel / beam, there is currently no clear method for how to determine the number of bits of the relevant indication field according to the different maximum transmission layers. In addition, the scheme of simultaneous transmission of multiple TRP / panel / beam can be switched with the scheme of single TRP / panel / beam transmission, and the maximum number of transmission layers supported by the scheme of simultaneous transmission of multiple TRP / panel / beam is also different from that of the scheme of single TRP / panel / beam transmission. Therefore, the number of DCI bits corresponding to different schemes is different, which will affect the blind detection of terminal devices.

[0073] Based on this, in one embodiment of the present application, an information processing method is provided. Referring to FIG2 , the information processing method may include the following steps:

[0074] Step 210: The terminal device determines the number of valid bits of the first information field according to the maximum number of transmission layers associated with one or more spatial parameters.

[0075] It should be understood that the spatial parameters can characterize the spatial relationship between the uplink and downlink channels transmitted by the terminal device. For example, the spatial relationship can include the panel, beam, or TRP of the uplink and downlink channels transmitted by the terminal device.

[0076] Optionally, the spatial parameters may include one or more of the following: reference signal set information, transmission configuration indicator (TCI) status information, panel information, TRP information, control resource set CORESET group information (coresetPoolIndex), and beam information.

[0077] Optionally, the reference signal set may include an SRS resource set. The SRS resource set may be associated with a panel / beam / TCI state. In practical applications, a terminal device may use the same panel / beam / TCI state as used to transmit the SRS resource set to transmit an uplink channel.

[0078] TCI state information can be used for uplink and downlink beam management. Among them, a TCI state may include Quasi Co-Location (QCL) type configuration and QCL reference signal configuration, the QCL type configuration may be one of QCL type A (typeA), QCL typeB, QCL typeC or QCL typeD, and the reference signal configuration may be a cell identifier (ID), a bandwidth part (BWP) ID and a reference signal identifier (such as a CSI-RS resource ID or an SSB index). Among them, the definitions of different QCL types are as follows: QCL TypeA is used to configure the following content {Doppler shift, Doppler spread, average delay, delay spread}, QCL typeB is used to configure {Doppler shift, Doppler spread}, QCL typeC is used to configure {Doppler shift, average delay}, and QCL typeD is used to configure {Spatial Rx parameter}.

[0079] If the network device configures the QCL reference signal of the target uplink channel as an SSB 1 resource through the TCI state, and the QCL type is configured as typeA, typeB or typeC, the terminal device can assume that the large-scale parameters of the above-mentioned target uplink signal and the SSB 1 resource are the same or similar, and the large-scale parameters are determined by the QCL type configuration.

[0080] It should be understood that if the transmission TRP or transmission panel or transmission beam of two uplink channels are different, different TCI states will usually be configured.

[0081] In the embodiment of the present application, the panel information may include a panel ID, or an index value of a panel, etc., which is not limited in the embodiment of the present application.

[0082] In an embodiment of the present application, coresetPoolIndex can be associated with a TRP. A network device can configure a coresetPoolIndex for each CORESET to indicate whether it is the same TRP. The value range of this value is 0 and 1. For CORESETs configured with the same coresetPoolIndex, the terminal device can be considered to be associated with the same TRP.

[0083] In addition, the beam information may include a beam ID, or a beam index value, etc., which is not limited in this embodiment of the present application.

[0084] Similarly, the TRP information may include a TRP ID, or an index value of a TPR, etc., which is not limited in this embodiment of the present application.

[0085] In an embodiment of the present application, the terminal device can be configured with multiple different spatial parameters, that is, the terminal device can transmit uplink channels through multiple different spatial relationships.

[0086] Optionally, as shown in FIG2 , before the terminal device transmits the uplink channel, the following steps may be performed:

[0087] Step 200: The network device sends first information to the terminal device, where the first information is carried in a first information field.

[0088] It should be understood that the network device can instruct the terminal device to transmit the transmission parameters of the uplink channel through the first information.

[0089] Optionally, the first information may include PTRS-DMRS association information, TPMI information, or SRI information. That is, the terminal device may determine the PTRS-DMRS association information, precoding matrix, or SRS resource information used when transmitting the uplink channel based on the first information.

[0090] In the embodiment of the present application, the first information may be carried by a first information field. It is understood that the first information field may be used to indicate transmission parameters when multiple TRPs / panels / beams are transmitted simultaneously. The first information field may include one or more of the following: a PTRS-DMRS association indication field, a TPMI field, and an SRI field.

[0091] In addition, in the embodiment of the present application, each of the multiple spatial parameters configured by the terminal device is associated with a maximum number of transmission layers. The maximum number of transmission layers associated with different spatial parameters in the multiple spatial parameters can be the same or different, and the embodiment of the present application does not impose any limitation on this.

[0092] Optionally, the maximum number of transmission layers associated with multiple spatial parameters can be determined based on the capabilities supported by the terminal device, or based on the configuration information sent by the network device. This embodiment of the present application does not impose any restrictions on this.

[0093] The value of the first information field is related to the number of valid bits in the first information field. After receiving the first information, the terminal device needs to first determine the number of valid bits in the first information field.

[0094] In an embodiment of the present application, the terminal device may determine the number of valid bits in the first information field based on at least one spatial parameter (that is, one or more spatial parameters) among multiple spatial parameters.

[0095] It should be understood that after determining the effective number of bits of the first information field, the terminal device can determine the value range of the first information field. In this way, the terminal device can determine the first information actually carried by the first information field based on the actual value of the first information field.

[0096] In summary, in the information processing method provided in the embodiments of the present application, multiple spatial parameters configured by a terminal device can each be associated with a maximum number of transmission layers, and the terminal device can determine the effective number of bits of the first information field based on one or more of the parameters. In this way, the terminal device can determine the information carried by the first information field based on the effective number of bits of the first information field.

[0097] It should be noted that the information processing method provided in the embodiment of the present application can be applied to scenarios where multiple TRPs / panels / beams simultaneously transmit uplink channels.

[0098] Optionally, the scheme for simultaneous transmission of multiple TRP / panel / beams may include a spatial division multiplexing (SDM) transmission scheme and a single frequency network (SFN) transmission scheme, etc.

[0099] In the SDM uplink transmission, different transmission layer sets of a PUSCH are sent to the same TRP or to different TRPs through different panels / beams of the terminal device, wherein the uplink resources of the different transmission layer sets of PUSCH are the same. For example, referring to the schematic diagram of SDM uplink transmission shown in Figure 3, the terminal device can send PUSCH 1 to TRP 1 through the transmission layer 0 of panel 1, and send PUSCH 2 to TRP 2 through the transmission layer 1 of panel 2, wherein PUSCH 1 is associated with the first TCI state and PUSCH 2 is associated with the second TCI state. PUSCH 1 and PUSCH 2 use the same time-frequency resources.

[0100] In addition, in SFN uplink transmission, repeated transmission of a PUSCH is sent to the same TRP or different TRPs through different panels / beams. The frequency domain resources used for repeated transmission of PUSCH are the same, the time domain resources are the same, and the DMRS ports are also the same. For example, referring to the schematic diagram of SFN uplink transmission shown in Figure 4, the terminal device can send PUSCH to TRP 1 through the transmission layer 0 of panel 1, and send repeated PUSCH transmission to TRP 2 through the transmission layer 1 of panel 2. The time-frequency resources for PUSCH and repeated PUSCH transmission are the same, and the DMRS ports are also the same.

[0101] In an embodiment of the present application, the terminal device determines the effective number of bits of the first information field according to the maximum number of transmission layers associated with one or more spatial parameters in multiple ways, two of which are described in detail below.

[0102] In one embodiment of the present application, in step 210, the terminal device determines the effective number of bits of the first information field based on the maximum number of transmission layers associated with one or more spatial parameters, which can be achieved by:

[0103] Step 2101: The terminal device determines the effective number of bits of the first information field according to the maximum number of transmission layers associated with multiple spatial parameters.

[0104] It should be understood that in an embodiment of the present application, the terminal device can determine the effective number of bits of the first information field based on the maximum number of transmission layers associated with each spatial parameter in the configured multiple spatial parameters.

[0105] The maximum number of transmission layers associated with each spatial parameter may be the same or different, and this embodiment of the present application does not impose any restrictions on this.

[0106] In a first implementation, if the number of the multiple spatial parameters is N and the maximum number of transmission layers associated with each spatial parameter is not limited, the effective number of bits of the first information field can be determined by:

[0107] The effective number of bits M of the first information field can be determined according to the following formula (1):

[0108]

[0109] in, Indicates rounding up, x i is the maximum number of transmission layers associated with the i-th spatial parameter, x i is an integer greater than or equal to 1.

[0110] For example, when N = 2, that is, when the terminal device is configured with two spatial parameters, if the maximum number of transmission layers associated with both spatial parameters is 1 (i.e., x1 = x2 = 1), then M = 0. If the maximum number of transmission layers associated with the two spatial parameters is 2 and the other is 1 (e.g., x1 = 1, x2 = 2), then M = 1. If the maximum number of transmission layers associated with both spatial parameters is 2 (i.e., x1 = x2 = 2), then M = 2. This is analogous and will not be further elaborated here.

[0111] For example, when N=3, that is, the terminal device is configured with 3 spatial parameters, if the maximum number of transmission layers associated with the three spatial parameters is 1 (that is, x1=x2=x3=1), then M=0. If one of the maximum number of transmission layers associated with the three spatial parameters is 2, and the other two are 1 (for example, x1=x2=1, x3=2), then M=1. If two of the maximum number of transmission layers associated with the three spatial parameters are 2, and the other one is 1 (for example, x1=x2=2, x3=1), then M=2. If the maximum number of transmission layers associated with the three spatial parameters is 2 (that is, x1=x2=x3=2), then M=3. And so on, I will not go into details here.

[0112] For example, when N = 4, that is, the terminal device is configured with 4 spatial parameters, if the maximum number of transmission layers associated with all four spatial parameters is 1 (that is, x1 = x2 = x3 = x4 = 1), then M = 0. If one of the four spatial parameters has a maximum number of transmission layers of 2 and the other is 1 (for example, x1 = x2 = x3 = 1, x4 = 2), then M = 1. If two of the four spatial parameters have a maximum number of transmission layers of 2 and the other two are 1 (for example, x1 = x2 = 1, x3 = x4 = 2), then M = 2. If three of the four spatial parameters have a maximum number of transmission layers of 2 and the other is 1 (for example, x1 = x2 = x3 = 2, x4 = 1), then M = 3. If the maximum number of transmission layers associated with all four spatial parameters is 2 (that is, x1 = x2 = x3 = x4 = 2), then M = 4. And so on, which will not be elaborated here.

[0113] It should be noted that the total number of bits in the first information field is greater than or equal to the number of valid bits in the first information field. When the total number of bits in the first information field is greater than the number of valid bits in the first information field, the valid bits in the first information field may be located in either the high-order bits or the low-order bits of the first information field, and this is not limited in this embodiment of the present application. For example, if the total number of bits in the first information field is 3 bits and the number of valid bits is 2 bits, then of the 3 bits in the first information field, either the first two bits are valid bits or the last two bits are valid bits.

[0114] Optionally, in some embodiments, the M valid bits of the first information field may include N parts, the i-th part corresponds to the i-th spatial parameter among the multiple spatial parameters, and the number of valid bits of the i-th part is

[0115] It should be understood that different portions of the M valid bits of the first information field may correspond to different spatial parameters. The portion of the first information field corresponding to a particular spatial parameter may be used to indicate a transmission parameter associated with the spatial parameter (e.g., a DMRS port, a precoding matrix, etc.).

[0116] Exemplarily, when the first information field is a PTRS-DMRS association indication field, the i-th part of the M valid bits of the first information field corresponding to the i-th spatial parameter can be used to indicate the association relationship between the PTRS port and the DMRS port associated with the i-th spatial parameter. Different values ​​of the i-th part in the first information field correspond to different association relationships between the PTRS port and the DMRS port. When the number of valid bits of the i-th part in the first information field is 1, if the value of the i-th part in the first information field is 0, it indicates that when associated with the i-th spatial parameter, the DMRS port associated with the PTRS port is the first DMRS port. If the value of the i-th part in the first information field is 1, it indicates that when associated with the i-th spatial parameter, the DMRS port associated with the PTRS port is the second DMRS port.

[0117] Optionally, in some other embodiments, the first information field includes N sub-information fields, the i-th sub-information field in the N sub-information fields corresponds to the i-th spatial parameter in the N spatial parameters, and the effective number of bits of the i-th sub-information field is

[0118] It should be understood that the first information field may include multiple sub-information fields, each of which may correspond to a spatial parameter. Each sub-information field may be used to indicate a transmission parameter associated with its corresponding spatial parameter (e.g., a DMRS port associated with a PTRS port associated with the spatial parameter, a precoding matrix, etc.).

[0119] In a second implementation, if the number of multiple spatial parameters is N, and the maximum number of transmission layers associated with each spatial parameter is at most 2, the effective number of bits of the first information field can be determined by:

[0120] When the maximum number of transmission layers associated with each of the N spatial parameters is 1, the number of valid bits in the first information field is 0.

[0121] When the k maximum transmission layer numbers among the maximum transmission layer numbers associated with N spatial parameters are 2 and the Nk maximum transmission layer numbers are 1, the effective number of bits of the first information field is k bits, where k is an integer greater than or equal to 1 and less than or equal to N.

[0122] Optionally, in some embodiments, among the k valid bits of the first information field, each valid bit corresponds to a specified space parameter among the N space parameters, and the maximum number of transmission layers associated with the specified space parameter is 2.

[0123] It can be understood that the spatial parameter with an associated maximum number of transmission layers of 2 can correspond to 1 bit among k valid bits, and each valid bit can be used to indicate the transmission parameter associated with the spatial parameter corresponding to the valid bit (for example, the DMRS port associated with the PTRS port associated with the spatial parameter, the precoding matrix, etc.).

[0124] Optionally, in some other embodiments, the first information field includes N sub-information fields, wherein the N sub-information fields correspond to N spatial parameters respectively.

[0125] Among the N spatial parameters, the effective number of bits of the sub-information field corresponding to the spatial parameter with an associated maximum number of transmission layers of 2 is 1 bit, and the effective number of bits of the sub-information field corresponding to the spatial parameter with an associated maximum number of transmission layers of 1 is 0 bit.

[0126] It is understandable that the first information field may include multiple sub-information fields, each of which may correspond to a spatial parameter. Each sub-information field may be used to indicate a transmission parameter (eg, DMRS port, precoding matrix, etc.) associated with its corresponding spatial parameter.

[0127] In a third implementation, if the multiple spatial parameters include a first spatial parameter and a second spatial parameter, the first spatial parameter is associated with a first maximum number of transmission layers, the second spatial parameter is associated with a second maximum number of transmission layers, and the maximum number of transmission layers associated with each spatial parameter is at most 2, then the effective number of bits of the first information field can be determined by:

[0128] When the first maximum number of transmission layers is 1 and the second maximum number of transmission layers is 1, the number of valid bits in the first information field is 0 bits;

[0129] When one of the first maximum number of transmission layers and the second maximum number of transmission layers is 1 and the other maximum number of transmission layers is 2, the effective number of bits of the first information field is 1 bit;

[0130] When the first maximum number of transmission layers and the second maximum number of transmission layers are both 2, the effective number of bits of the first information field is 2 bits.

[0131] Optionally, in some embodiments, when one of the first maximum number of transmission layers and the second maximum number of transmission layers is 1 and the other maximum number of transmission layers is 2, the first information domain may correspond to a specified spatial parameter, and the maximum number of transmission layers associated with the specified spatial parameter is 2.

[0132] It can be understood that one valid bit in the first information field may correspond to a spatial parameter with a maximum number of transmission layers of 2, and the valid bit may indicate a transmission parameter associated with the spatial parameter with a maximum number of transmission layers of 2.

[0133] Assuming that the first information field is a PTRS-DMRS association field, Table 4 shows a specific indication method of the bit when the number of valid bits of the PTRS-DMRS association field is 1 bit.

[0134] Table 4

[0135]

[0136] As can be seen from Table 4, when the value of the PTRS-DMRS association field is 0, the DMRS port associated with the PTRS port associated with the spatial parameter with a maximum number of transmission layers of 2 is the first scheduled DMRS port. When the value of the PTRS-DMRS association field is 1, the DMRS port associated with the PTRS port associated with the spatial parameter with a maximum number of transmission layers of 2 is the second scheduled DMRS port.

[0137] In addition, when the first maximum number of transmission layers and the second maximum number of transmission layers are both 2, the two valid bits of the first information field correspond to the first space parameter and the second space parameter, respectively.

[0138] It is understandable that the high-order bit of the two valid bits of the first information field corresponds to one of the first and second spatial parameters, and the low-order bit of the two valid bits corresponds to the other spatial parameter. For example, the high-order bit of the two valid bits corresponds to the spatial parameter with a smaller index, and the low-order bit of the two valid bits corresponds to the spatial parameter with a larger index. Alternatively, the high-order bit of the two valid bits corresponds to the spatial parameter with a larger index, and the low-order bit of the two valid bits corresponds to the spatial parameter with a smaller index.

[0139] Taking the first information field as the PTRS-DMRS association field for illustration, Table 5 shows the specific indication method of different bits when the effective number of bits of the PTRS-DMRS association field is 2 bits, and the high-order bit of the PTRS-DMRS association field corresponds to the first space parameter and the low-order bit corresponds to the second space parameter.

[0140] Table 5

[0141]

[0142] As can be seen from Table 5, when the value of the high-order bit in the PTRS-DMRS association domain is 0, the DMRS port associated with the PTRS port associated with the first spatial parameter is the first scheduled DMRS port. When the value of the high-order bit in the PTRS-DMRS association domain is 1, the DMRS port associated with the PTRS port associated with the first spatial parameter is the second scheduled DMRS port. When the value of the low-order bit in the PTRS-DMRS association domain is 0, the DMRS port associated with the PTRS port associated with the second spatial parameter is the first scheduled DMRS port. When the value of the low-order bit in the PTRS-DMRS association domain is 1, the DMRS port associated with the PTRS port associated with the second spatial parameter is the second scheduled DMRS port.

[0143] Optionally, different space parameters in the multiple space parameters correspond to different PTRS ports. For example, the multiple space parameters include a first space parameter and a second space parameter, the first space parameter corresponds to PTRS port 0, and the second space parameter corresponds to PTRS port 1. With respect to Table 5, the high-order bit corresponds to the first space parameter, i.e., to PTRS port 0, and the low-order bit corresponds to the second space parameter, i.e., to PTRS port 1.

[0144] Optionally, different space parameters in the multiple space parameters correspond to the same PTRS port. For example, the multiple space parameters include a first space parameter and a second space parameter, and the first space parameter and the second space parameter both correspond to PTRS port 0. Furthermore, when different space parameters in the multiple space parameters correspond to the same PTRS port, the DMRS ports corresponding to the PTRS ports are also the same. Alternatively, when different space parameters in the multiple space parameters correspond to the same PTRS port, the PTRS segment cassette may also correspond to different DMRS ports.

[0145] Optionally, in some other embodiments, the first information field may include a first sub-information field and a second sub-information field, the first sub-information field corresponds to the first spatial parameter, and the second sub-information field corresponds to the second spatial parameter.

[0146] It is understandable that the first sub-information field can be used to indicate the transmission parameters associated with the first spatial parameter (e.g., DMRS port, precoding matrix, etc.). The second sub-information field can be used to indicate the transmission parameters associated with the second spatial parameter (e.g., DMRS port, precoding matrix, etc. associated with the PTRS port associated with the spatial parameter).

[0147] Among them, when one of the first maximum number of transmission layers and the second maximum number of transmission layers is 1 and the other maximum number of transmission layers is 2, the effective number of bits of the first target sub-information field in the first information field is 0 bits, and the effective number of bits of the second target sub-information field is 1 bit; wherein, the first target sub-information field is the sub-information field corresponding to the spatial parameter with the maximum number of transmission layers being 1, and the second target sub-information field is the sub-information field corresponding to the spatial parameter with the maximum number of transmission layers being 2.

[0148] It can be understood that, when one of the first maximum number of transmission layers and the second maximum number of transmission layers is 1 and the other maximum number of transmission layers is 2, the effective number of bits in the sub-information domain corresponding to the spatial parameter with the associated maximum transmission layer number value of 2 in the first information domain is 1 bit, and the effective number of bits in the sub-information domain corresponding to the spatial parameter with the associated maximum transmission layer data value of 1 is 0 bits.

[0149] That is, when the first maximum number of transmission layers is 1 and the second maximum number of transmission layers is 2, the number of valid bits of the first sub-information field in the first information field is 0, and the number of valid bits of the second sub-information field is 1. When the first maximum number of transmission layers is 2 and the second maximum number of transmission layers is 1, the number of valid bits of the first sub-information field in the first information field is 1, and the number of valid bits of the second sub-information field is 0.

[0150] In addition, when the first maximum number of transmission layers and the second maximum number of transmission layers are both 2, the effective bit numbers of the first sub-information field and the second sub-information field are both 1 bit.

[0151] Exemplarily, the first information field is taken as the PTRS-DMRS association field for description. Table 6 shows the indication method of each sub-information field with a valid number of bits in the PTRS-DMRS association field.

[0152] Table 6

[0153]

[0154] As can be seen from Table 6, when the value of the sub-information field with a valid number of bits is 0, the DMRS port associated with the PTRS port associated with the spatial parameter corresponding to the sub-information field is the first scheduled DMRS port. When the value of the sub-information field with valid bit data is 1, the DMRS port associated with the spatial parameter corresponding to the sub-information field is the second scheduled DMRS port.

[0155] In another embodiment of the present application, in step 210, the terminal device determines the effective number of bits of the first information field based on the maximum number of transmission layers associated with one or more spatial parameters, which can also be implemented in the following manner:

[0156] Step 2102: The terminal device determines the valid number of bits of the first information field according to the third maximum number of transmission layers; the third maximum number of transmission layers is associated with multiple spatial parameters.

[0157] It should be understood that the maximum number of transmission layers associated with the multiple spatial parameters is the third number of transmission layers. In other words, the maximum number of transmission layers associated with the multiple spatial parameters is the same, which is the third number of transmission layers.

[0158] In a first implementation, if the number of the plurality of spatial parameters is N and the third maximum number of transmission layers is any integer greater than or equal to 1, the effective number of bits of the first information field may be determined as follows:

[0159] The effective number of bits M of the first information field is determined according to the following formula (2):

[0160]

[0161] in, Indicates rounding up, where y is the third maximum number of transmission layers.

[0162] For example, when N=3, that is, the terminal device is configured with three spatial parameters, if y=1, the effective number of bits in the first information field is 0; if y=2, the effective number of bits in the first information field is 3, with each spatial parameter corresponding to one bit; if y=3, the effective number of bits in the first information field is 6, with each spatial parameter corresponding to two bits. This is analogous and will not be detailed here.

[0163] Optionally, in some embodiments, the M valid bits of the first information field may include N parts, the i-th part corresponds to the i-th spatial parameter among the multiple spatial parameters, and the number of valid bits of the i-th part is

[0164] It should be understood that different portions of the M valid bits of the first information field may correspond to different spatial parameters. The portion corresponding to a particular spatial parameter may be used to indicate a transmission parameter associated with the spatial parameter (e.g., a DMRS port associated with a PTRS port associated with the spatial parameter, a precoding matrix, etc.).

[0165] When the first information field is a PTRS-DMRS association indication field, the i-th part of the M valid bits of the first information field corresponding to the i-th spatial parameter can be used to indicate the association relationship between the PTRS port and the DMRS port associated with the i-th spatial parameter. Different values ​​of the i-th part in the first information field correspond to different association relationships between the PTRS port and the DMRS port. When the number of valid bits of the i-th part in the first information field is 1, if the value of the i-th part in the first information field is 0, it indicates that when associated with the i-th spatial parameter, the DMRS port associated with the PTRS port is the first DMRS port. If the value of the i-th part in the first information field is 1, it indicates that when associated with the i-th spatial parameter, the DMRS port associated with the PTRS port is the second DMRS port.

[0166] Optionally, in some other embodiments, the first information field includes N sub-information fields, the i-th sub-information field among the N sub-information fields corresponds to the i-th spatial parameter among the N spatial parameters, and the effective number of bits of the i-th sub-information field is

[0167] It should be understood that the first information field may include multiple sub-information fields, each of which may correspond to a spatial parameter. Each sub-information field may be used to indicate a transmission parameter associated with its corresponding spatial parameter (e.g., a DMRS port associated with a PTRS port associated with the spatial parameter, a precoding matrix, etc.).

[0168] In a second implementation, if the number of multiple spatial parameters is N, and the maximum number of transmission layers associated with each spatial parameter is at most 2, the effective number of bits of the first information field can be determined by:

[0169] When the third maximum number of transmission layers is 1, the valid number of bits in the first information field is 0 bits; when the third maximum number of transmission layers is 2, the valid number of bits in the first information field is N bits.

[0170] In some embodiments, when the third maximum number of transmission layers is 2, the N valid bits in the first information field correspond to N space parameters respectively. Each of the N valid bits in the first information field corresponds to a space parameter.

[0171] In other embodiments, the first information field includes N sub-information fields, wherein the N sub-information fields correspond to N spatial parameters respectively. When the third maximum number of transmission layers is 2, the effective number of bits of the N sub-information fields is 1 bit.

[0172] In a third implementation, if the multiple spatial parameters include a first spatial parameter and a second spatial parameter, the first spatial parameter is associated with a first maximum number of transmission layers, the second spatial parameter is associated with the second maximum number of transmission layers, and the third maximum number of transmission layers is at most 2, then the effective number of bits of the first information field can be determined by:

[0173] When the third maximum number of transmission layers is 1, the number of valid bits in the first information field is 0 bits;

[0174] When the third maximum number of transmission layers is 2, the number of valid bits of the first information field is 2 bits.

[0175] In a possible implementation, when the third maximum number of transmission layers is 2, the two bits of the first information field correspond to the first space parameter and the second space parameter, respectively.

[0176] In another possible implementation, the first information domain includes a first sub-information domain and a second sub-information domain, the first sub-information domain corresponds to the first space parameter, and the second sub-information domain corresponds to the second space parameter; wherein, when the third maximum number of transmission layers is 2, the effective number of bits of the first sub-information domain and the second sub-information domain are both 1 bit.

[0177] In an embodiment of the present application, referring to FIG5 , the information processing method provided in the embodiment of the present application may further include the following steps:

[0178] Step 220: The terminal device sends second information to the network device. Correspondingly, the network device receives the second information sent by the terminal device. The second information is used to indicate the maximum number of transmission layers supported by the terminal device.

[0179] It should be understood that there are multiple ways to configure the maximum number of transmission layers. The configuration method for the maximum number of transmission layers is related to the maximum number of transmission layers that can be configured on the terminal device. In different configuration methods, the maximum number of transmission layers configured on the terminal device may vary. For example, the terminal device may support configuration of 1 maximum number of transmission layers, 2 maximum number of transmission layers, N maximum number of transmission layers, etc.

[0180] The design of the first information field corresponding to different configuration modes of the maximum number of transmission layers is different. Based on this, the terminal device can report the configuration it supports to the network device.

[0181] Optionally, the second information may be sent via dedicated signaling or via capability information of the terminal device (eg, UECapabilityInformation), and this application does not impose any restrictions on this.

[0182] In some embodiments, the second information may be used to indicate one or more of the following:

[0183] The terminal device supports configuring N+1 maximum transmission layers, N maximum transmission layers among the N+1 maximum transmission layers (for example, the first N maximum transmission layers among the N+1 maximum transmission layers, or the last N maximum transmission layers) are used for the first transmission mode, and the remaining maximum transmission layer among the N+1 maximum transmission layers (for example, the N+1th maximum transmission layer among the N+1 maximum transmission layers, or the first maximum transmission layer) is used for the second transmission mode;

[0184] The terminal device supports configuring N maximum transmission layers, where the N maximum transmission layers are used for the first transmission mode, a specified maximum transmission layer among the N maximum transmission layers is used for the second transmission mode, and a spatial parameter associated with the specified maximum transmission layer is the same as a spatial parameter associated with the second transmission mode;

[0185] The terminal device supports configuring two maximum transmission layers, one of which is used for the first transmission mode and the other is used for the second transmission mode;

[0186] The terminal device supports configuring one maximum number of transmission layers, one maximum transmission layer for the first transmission mode and one maximum transmission layer for the second transmission mode;

[0187] Among them, the first transmission mode includes simultaneous transmission of multiple TRP / panel / beams, and the second transmission mode includes single TRP / panel / beam transmission.

[0188] It should be noted that the terminal device can simultaneously support a first transmission mode in which multiple TRPs / panels / beams are transmitted simultaneously, and a second transmission mode in which a single TRP / panel / beam is transmitted. The configuration method of the maximum transmission layer of the terminal device can be related to the first transmission mode and the second transmission mode.

[0189] It should be noted that the maximum number of transmission layers supported by the terminal device belongs to the capability of the terminal device. In the embodiment of the present application, the terminal device may have the following four capabilities.

[0190] Capability A: The terminal device supports the configuration of N+1 maximum transmission layers. N of the N+1 maximum transmission layers are used for simultaneous transmission of multiple TRPs / panels / beams, and the remaining one of the N+1 maximum transmission layers is used for transmission of a single TRP / panel / beam.

[0191] It is understood that if a terminal device is configured with N spatial parameters, the terminal device can support configuration of N+1 maximum transmission layers. Specifically, the terminal device can configure a maximum transmission layer for each of the N spatial parameters in the first transmission mode, and a maximum transmission layer for single TRP / panel / beam transmission in the second transmission mode.

[0192] In the first transmission mode, the maximum number of transmission layers for each spatial parameter configuration may be the same or different, and this embodiment of the present application does not impose any restrictions on this. Furthermore, the N maximum number of transmission layers configured in the first transmission mode may be the same as or different from the 1 maximum number of transmission layers configured in the second transmission mode, and this embodiment of the present application does not impose any restrictions on this.

[0193] Capability B: The terminal device supports configuring N maximum transmission layers, where the N maximum transmission layers are used for the first transmission mode, and a specified maximum transmission layer among the N maximum transmission layers is used for the second transmission mode, and the spatial parameters associated with the specified maximum transmission layers are the same as the spatial parameters associated with the second transmission mode.

[0194] It is understandable that the terminal device may support configuration of N maximum transmission layers. The N maximum transmission layers may correspond one-to-one to the N spatial parameters configured in the terminal device.

[0195] In the first transmission mode, when multiple TRP / panel / beam are transmitted, the maximum number of transmission layers associated with different spatial parameters can be the same or different, and the embodiments of the present application do not impose any restrictions on this.

[0196] In the second transmission mode, the maximum number of transmission layers associated with a single TRP / panel / beam transmission may be a specified maximum number of transmission layers among the N maximum numbers of transmission layers. The spatial parameters associated with the specified maximum number of transmission layers are the same as the spatial parameters associated with the single TRP / panel / beam transmission.

[0197] Capability C: The terminal device supports configuration of two maximum transmission layers, one of the two maximum transmission layers is used for the first transmission mode, and the other is used for the second transmission mode.

[0198] It is understandable that, in the first transmission mode, the maximum number of transmission layers associated with the N spatial parameters are all the same. Exemplarily, with reference to the description of the above embodiment, the N spatial parameters may be associated with a third maximum number of transmission layers.

[0199] It should be noted that, in this configuration, the maximum number of transmission layers used for the first transmission mode and the maximum number of transmission layers used for the second transmission mode may be the same or different, and the implementation of this application does not impose any restrictions on this.

[0200] Capability D: The terminal device supports configuring a maximum number of transmission layers, which is used for the first transmission mode and the second transmission mode.

[0201] It is understandable that the terminal device can be configured with only one maximum number of transmission layers, and the maximum number of transmission layers can be used for the first transmission mode and / or the second transmission mode.

[0202] Optionally, when the terminal device supports configuring one maximum number of transmission layers, the maximum number of transmission layers associated with the multiple spatial parameters is the minimum value of the first number and the second number.

[0203] That is to say, when the terminal device only supports configuring one maximum number of transmission layers, in the first transmission mode, the maximum number of transmission layers associated with multiple spatial parameters configured by the terminal device can be min{first number, second number}.

[0204] The first number is the maximum number of transmission layers supported by each TRP / panel / beam in the first transmission mode, that is, when multiple TRPs / panels / beams simultaneously transmit uplink channels, the maximum number of uplink channel layers that each TRP / panel / beam can transmit. For example, the first number is 2. In addition, the second number is the maximum number of transmission layers supported by a single TRP / panel / beam in the second transmission mode.

[0205] In an embodiment of the present application, the terminal device may report one or more of the above four capabilities to the network device via the second information, so that the network device can perform uplink scheduling on the terminal device based on the reported capabilities. Since the configuration method of the maximum number of transmission layers has a significant impact on the design and number of bits of the DCI sent by the network device side, and also has a significant impact on the blind detection of the terminal device, the configuration of the maximum number of transmission layers reported by the terminal device has a high degree of flexibility.

[0206] Optionally, referring to FIG5 , based on step 220, the information processing method provided in the embodiment of the present application further includes the following steps:

[0207] Step 230: The terminal device sends third information to the network device. Correspondingly, the network device receives the third information sent by the terminal device. The third information is used to indicate the number of each maximum number of transmission layers in the maximum number of transmission layers supported by the terminal device.

[0208] It is understandable that, in addition to reporting the number of maximum transmission layers supported for configuration to the network device, the terminal device may also report the specific number of each maximum transmission layer supported for configuration to the network device.

[0209] Exemplarily, when the terminal device supports configuring N+1 maximum transmission layers, the specific number of each maximum transmission layer in the N+1 maximum transmission layers can be reported to the network device through the third information. When the terminal device supports configuring N maximum transmission layers, the specific number of each transmission layer in the N maximum transmission layers can be reported to the network device through the third information.

[0210] It should be noted that the third information can be sent via dedicated signaling or via the capability information of the terminal device. In addition, the third information and the second information can be the same information or different information. This embodiment of the application does not limit this.

[0211] For example, the terminal device may report the number of maximum transmission layers supported by the terminal device and the specific number of each maximum transmission layer to the network device through UECapabilityInformation.

[0212] In some embodiments, the maximum number of transmission layers associated with the plurality of spatial parameters, and / or the third maximum number of transmission layers, are determined according to any one of the following:

[0213] The maximum number of transmission layers supported by the terminal device;

[0214] Configuration information sent by network devices;

[0215] Predefined rules.

[0216] In one possible implementation, the maximum number of transmission layers associated with the multiple spatial parameters, and / or the third maximum number of transmission layers can be configured by the network device, or can be determined by a predefined rule. The predefined rule can be implemented by pre-saving the corresponding code, table or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device). The present application does not limit its specific implementation. In some embodiments, the predefined rule can also be a predefined value. For example, the predefined value can be 2, 4, etc., which is not limited in the embodiments of the present application.

[0217] In another possible implementation, the terminal device can determine the maximum number of transmission layers associated with multiple spatial parameters in the above embodiment, and / or the third maximum number of transmission layers based on the number of maximum number of transmission layers it supports and the specific number of each maximum number of transmission layers.

[0218] For example, a terminal device configured with N spatial parameters is used as an example for description. If the terminal device supports configuration of N+1 maximum transmission layers, the terminal device can determine the maximum transmission layers associated with each of the N spatial parameters based on the N maximum transmission layers used for the first transmission mode among the N+1 maximum transmission layers. The maximum transmission layers associated with different spatial parameters can be the same or different. If the maximum transmission layers associated with the N spatial parameters are the same, the third maximum transmission layer number described in the above embodiment can be obtained.

[0219] If the terminal device supports configuring N maximum transmission layers, the terminal device can determine the maximum transmission layer numbers associated with the N spatial parameters based on the N maximum transmission layer numbers. The maximum transmission layer numbers associated with different spatial parameters can be the same or different. If the maximum transmission layer numbers associated with the N spatial parameters are the same, the third maximum transmission layer number described in the above embodiment can be obtained.

[0220] When the terminal device supports configuring two maximum transmission layers, the terminal device can determine the maximum transmission layer number associated with the above N spatial parameters based on the maximum transmission layer number used for the first transmission mode among the two maximum transmission layers to obtain the third maximum transmission layer number.

[0221] If the terminal device is configured with only one maximum number of transmission layers, the third maximum number of transmission layers = min{first number, second number}. The second number is the maximum number of transmission layers for single TRP / panel / beam transmission, or it may be the maximum number of transmission layers configured only for the terminal device in this implementation.

[0222] That is, the maximum number of transmission layers associated with each of the multiple spatial parameters may be different from the second number. Alternatively, the specified maximum number of transmission layers among the maximum numbers of transmission layers associated with each of the multiple spatial parameters may be the same as the second number; and the spatial parameter associated with the specified maximum number of transmission layers may be the same as the spatial parameter associated with the second transmission mode.

[0223] In addition, the third maximum number of transmission layers is different from the second number. Alternatively, the third maximum number of transmission layers is the minimum value between the first number and the second number.

[0224] In another possible implementation, when the terminal device reports to the network device the number of maximum transmission layers that it supports for configuration, and the number of each maximum transmission layer number, through the second information and / or the third information, the network device may configure the maximum transmission layers that are respectively associated with multiple spatial parameters in actual applications, and / or the third maximum transmission layer number for the terminal device based on the above-mentioned capabilities reported by the terminal device. When the terminal device reports to the network device the number of maximum transmission layers that it supports for configuration, and the number of each maximum transmission layer number, through the second information and / or the third information, the terminal device and the network device may also determine the maximum transmission layers that are respectively associated with multiple spatial parameters in actual applications, and / or the third maximum transmission layer number, based on predefined rules.

[0225] In some embodiments, the terminal device can switch between the first transmission mode and the second transmission mode. Optionally, the terminal device can switch between the first transmission mode and the second transmission mode according to instructions from the network device. It should be understood that in the first transmission mode, the terminal device can determine the number of valid bits of the first information field according to the method provided in the above embodiment.

[0226] In one embodiment of the present application, in step 210, the terminal device determines the effective number of bits of the first information field based on the maximum number of transmission layers associated with one or more spatial parameters, which can also be implemented based on the following methods:

[0227] Upon receiving the fourth information, the terminal device determines the valid number of bits of the first information field based on the maximum number of transmission layers associated with the one or more spatial parameters;

[0228] The fourth information is used to indicate simultaneous transmission through multiple TRPs / panels / beams.

[0229] It should be noted that the fourth information can be used to indicate simultaneous transmission through multiple TRP / panel / beams, and can also be used to indicate transmission through a single TRP / panel / beam.

[0230] The fourth information is used to indicate simultaneous transmission through multiple TRPs / panels / beams. It can be understood that the fourth information can instruct the terminal device to use the first transmission mode for uplink channel transmission. Or it can instruct the terminal device to simultaneously apply multiple spatial parameters to send uplink channels, or it can instruct the terminal device to use the SDM / SFN solution to send uplink channels.

[0231] The fourth information is used to indicate transmission through a single TRP / panel / beam. It can be understood that the fourth information can instruct the terminal device to adopt the second transmission mode for uplink channel transmission.

[0232] Exemplarily, if the fourth information takes the first value (for example, "10" or "11"), it indicates that the terminal device transmits the uplink channel simultaneously through multiple TRP / panel / beams; if the fourth information takes the second value (for example, "01" or "00"), it indicates that the terminal device transmits the uplink channel through a single TRP / panel / beam.

[0233] Exemplarily, the fourth information may be first SRS resource set indication information, and the first SRS resource set indication information is used to indicate an SRS resource set. When the first SRS resource set indication information is used to indicate multiple SRS resources, it may implicitly indicate that the terminal device transmits uplink channels simultaneously through multiple TRPs / panels / beams. When the first SRS resource set indication information is used to indicate one SRS resource, it may indicate that the terminal device transmits through a single TRP / panel / beam. Alternatively, when the first SRS resource set indication information takes a first value (for example, "10" or "11"), it indicates that the terminal device transmits uplink channels simultaneously through multiple TRPs / panels / beams, and when the first SRS resource set indication information takes a second value (for example, "01" or "00"), it indicates that the terminal device transmits uplink channels through a single TRP / panel / beam.

[0234] In an embodiment of the present application, when the fourth information is used to indicate simultaneous transmission via multiple TRPs / panels / beams, the terminal device may determine the maximum number of transmission layers associated with one or more spatial parameters to determine the effective number of bits of the first information field. The manner in which the terminal device determines the effective number of bits of the first information field based on the maximum number of transmission layers associated with one or more spatial parameters is the same as that described in the above embodiment and is not further described here for the sake of brevity.

[0235] In one embodiment of the present application, a terminal device receives a first DCI, which is a DCI for scheduling simultaneous transmission of multiple TRPs / panels / beams, and includes a first information field. In other words, the first information field in the embodiment of the present application can be carried by the first DCI.

[0236] In one possible implementation, the total number of bits of the first DCI is the same as the total number of bits of the second DCI, and the second DCI is a DCI that schedules a single TRP / panel / beam transmission.

[0237] It should be understood that in the scenario of switching between the first transmission mode and the second transmission mode, in order to avoid an increase in the number of blind detections of the terminal device, the network device can set the total number of bits of the first DCI scheduled for simultaneous transmission of multiple TRPs / panels / beams to be the same as the total number of bits of the second DCI scheduled for transmission of a single TRP / panel / beam. That is, the total number of bits of the first DCI and the second DCI are aligned.

[0238] Optionally, the total number of bits of the first DCI and the total number of bits of the second DCI is the maximum value of the valid number of bits of the first DCI and the valid number of bits of the second DCI.

[0239] It should be understood that the effective number of bits of the first DCI is recorded as the first bit number, and the effective number of bits of the second DCI is recorded as the second bit number. The total number of bits of the first DCI and the second DCI = max{first bit number, second bit number}.

[0240] In which, when the valid number of bits of the first DCI is different from the valid number of bits of the second DCI, the total number of bits of the DCI with a smaller valid number of bits in the first DCI or the second DCI is padded with zeros until the total number of bits is the same as the total number of bits of the DCI with a larger valid number of bits.

[0241] That is, the network device can pad the DCI with a smaller number of valid bits with zeros to align the total number of bits of the first DCI and the second DCI, so that the total number of bits of the first DCI is the same as the total number of bits of the second DCI. For example, if the number of valid bits of the first DCI is less than the number of valid bits of the second DCI, zero padding is performed after the valid number of bits of the first DCI, that is, zero padding starts from the high-order bits. In addition, zero padding can also be performed from the low-order bits, which is not limited in this embodiment of the present application.

[0242] It can be seen that the information processing method provided in the embodiment of the present application can align the total number of bits of the first DCI scheduled for simultaneous transmission of multiple TRPs / panels / beams and the total number of bits of the second DCI scheduled for transmission of a single TRP / panel / beam, so that the total number of bits of the first DCI and the total number of bits of the second DCI are the same. In this way, when the terminal device dynamically switches between the first transmission mode and the second transmission mode, the terminal device avoids an increase in the number of blind detections due to the difference in the total number of bits of the first DCI and the second DCI.

[0243] In another possible implementation, the second DCI may include a second information field, and the second information field has the same function as the first information field; wherein the total number of bits of the second information field is the same as the total number of bits of the first information field.

[0244] In this implementation, the total number of bits of the first information field and the second information field with the same function in the first DCI and the second DCI can be set to be the same, that is, the total number of bits of the information field with the same function in the first DCI and the second DCI are aligned.

[0245] Exemplarily, the second information field may include one or more of the following: a PTRS-DMRS association field, a TPMI field, and an SRI field.

[0246] Optionally, the total number of bits of the first information field and the total number of bits of the second information field is the maximum value of the effective number of bits of the first information field and the effective number of bits of the second information field.

[0247] Here, the effective number of bits in the first information field is recorded as the first bit number, and the effective number of bits in the second information field is recorded as the second bit number. The total number of bits in the first information field and the second information field in the first DCI and the second DCI = max{first bit number, second bit number}.

[0248] In the case where the effective bit number of the second information field is different from the effective bit number of the first information field, the information field with the smaller effective bit number in the first information field or the second information field is padded with zeros until the total number of bits is the same as the total number of bits of the information field with the larger effective bit number.

[0249] That is, the network device can pad the DCI with a smaller number of valid bits with zeros to align the total number of bits of the first DCI and the second DCI, so that the total number of bits of the first DCI is the same as the total number of bits of the second DCI. For example, if the number of valid bits of the first DCI is less than the number of valid bits of the second DCI, zero padding is performed after the valid number of bits of the first DCI, that is, zero padding starts from the high-order bits. In addition, zero padding can also be performed from the low-order bits, which is not limited in this embodiment of the present application.

[0250] Optionally, after performing a zero padding operation on the first information field or the second information field so that the total number of bits of the first information field and the second information field are the same, if the total number of bits of the first DCI carrying the first information field and the second DCI carrying the second information field are different, the first DCI and the second DCI with the smaller number of bits can be padded with zeros so that the total number of bits of the first DCI and the second DCI are the same.

[0251] Thus, it can be seen that the information processing method provided in the embodiment of the present application can align the total number of bits of information fields with the same function, so that the total number of bits of information fields with the same function is the same. At the same time, the total number of bits of the first DCI and the second DCI can also be aligned. In this way, when the terminal device dynamically switches between the first transmission mode and the second transmission mode, the terminal device avoids an increase in the number of blind detections due to the difference in the total number of bits of the first DCI and the second DCI.

[0252] In another possible implementation, the second DCI includes a second information field, and the second information field has the same function as the first information field; wherein, the first information field includes N sub-information fields, and the N sub-information fields correspond to multiple spatial parameters respectively; the total number of bits of the specified sub-information field in the first information is the same as the total number of bits of the second information field; the spatial parameter corresponding to the specified sub-information field is the same as the spatial parameter associated with the second information field.

[0253] In this implementation, the network device may set the total number of bits of the information fields of the same function associated with the same spatial parameters in the first DCI and the second DCI to be the same, that is, align the number of bits of the information fields of the same function associated with the same spatial parameters.

[0254] It should be understood that the first DCI may be a DCI for scheduling simultaneous transmission of multiple TRPs / panels / beams, and the first information field in the first DCI may correspond to multiple different spatial parameters. The second DCI may be a DCI for scheduling transmission of a single TRP / panel / beam, and the second information field in the second DCI may correspond to the spatial parameters of the single TRP / panel / beam transmission.

[0255] Optionally, the total number of bits of the target sub-information field and the total number of bits of the second information field is the maximum value of the effective number of bits of the target sub-information field and the effective number of bits of the second information field.

[0256] In which, when the effective number of bits of the target sub-information field is different from the effective number of bits of the second information field, the target sub-information field or the information field with the smaller effective number of bits in the second information field is padded with zeros until the total number of bits is the same as the total number of bits of the information field with the larger effective number of bits.

[0257] Exemplarily, the effective number of bits of the first information field is recorded as the first bit number. The first information field may include a first sub-information field and a second sub-information field. The first sub-information field is associated with the first spatial parameter, and the second sub-information field is associated with the second spatial parameter. The effective number of bits of the first sub-information field is recorded as the third bit number, and the effective number of bits of the second sub-information field is recorded as the fourth bit number. The effective number of bits of the second information field in the second DCI is the second bit number, and the second information field may be associated with the first spatial parameter or the second spatial parameter. If the second information field is associated with the first spatial parameter, the total number of bits of the first sub-information field associated with the first spatial parameter in the first information field is the same as the total number of bits of the second information field, specifically max{third bit number, second bit number}. If the second information field is associated with the second spatial parameter, the total number of bits of the second sub-information field associated with the second spatial parameter in the first information field is the same as the total number of bits of the second information field, specifically max{fourth bit number, second bit number}.

[0258] Optionally, after performing a zero padding operation on the target sub-information field or the second information field in the first information field so that the total number of bits of the target sub-information field and the second information field are the same, if the total number of bits of the first DCI carrying the first information field and the second DCI carrying the second information field are different, the first DCI and the second DCI with the smaller number of bits can be padded with zeros so that the total number of bits of the first DCI and the second DCI are the same.

[0259] It can be seen that the information processing method provided in the embodiment of the present application can align the number of bits of the information field of the same function associated with the same spatial parameter in the first DCI and the second DCI, thereby avoiding changes in the number of bits of the same function corresponding to the same spatial parameter when switching between the first transmission mode and the second transmission mode. At the same time, the total number of bits of the first DCI and the second DCI can also be aligned. In this way, when the terminal device dynamically switches between the first transmission mode and the second transmission mode, the number of blind detections of the terminal device is avoided due to the difference in the total number of bits of the first DCI and the second DCI.
