The wireless terminal device may communicate with one or more core networks (CN) through a Radio Access Network (RAN), and the wireless terminal device may be a mobile terminal device, such as a mobile phone (also called a "cellular" phone) and a computer with a mobile terminal device, such as a mobile, pocket, handheld, computer-embedded or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), etc. The wireless terminal equipment may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, and is not limited to the embodiments of the present disclosure.

[0121] The network equipment according to the embodiment of the present disclosure may be a base station, which may include multiple cells serving terminals. Depending on the specific application, the base station may be called an access point, or may be a device that communicates with wireless terminal equipment through one or more sectors over an air interface in an access network, or may be other names. The network equipment is used to exchange received air frames and Internet Protocol (IP) packets, and may be a router between the wireless terminal equipment and the rest of the access network, which may include an Internet Protocol (IP) communication network.

[0122] Between the network device and the terminal device, multiple input multiple output (MIMO) transmission can be performed using one or more antennas, and the MIMO transmission may be single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Based on the form and number of root antenna combinations, the MIMO transmission may be 2D-MIMO (2 Dimension MIMO, 2D-MIMO), 3D-MIMO (3 Dimension MIMO, 3D-MIMO), FD-MIMO (Full Dimension MIMO, FD-MIMO) or massive-MIMO, and may be diversity transmission, precoding transmission, beamforming transmission, etc.

[0125] The common points of the transmission programs (1)-(5) are as follows:

[0126] (1) There is a one-to-one mapping between the layers of the downlink signal and the demodulation reference signal (DMRS) port.

[0127] (2) The quasi co-location (QCL) information of a downlink signal and its DMRS port is determined based on a Transmission Configuration Indicator (TCI) codepoint including two TCI states, which can be called a TCI codepoint corresponding to a downlink signal. The information in the TCI state associated with the TCI codepoint is the QCL information of the downlink signal. The reference signal in the TCI state associated with the TCI codepoint is the QCL reference signal of the downlink signal.

[0128] The difference between the transmission programs (1) to (5) is that the association relationship between the Transmission Configuration Indication state (TCI state) and the DMRS port of the downlink signal in the time-frequency resource is different.

[0129] One TCI state may include a TCI state identifier, a QCL type, and a reference signal corresponding to the QCL type. For example, as a method of setting a TCI state, the TCI state includes QCL type information (e.g., qcl-Type1, indicated by QCL-Info) and a TCI state identifier (e.g., tci-StateId, indicated by TCI-StateId). Each QCL type information is indicated by QCL-Info, which includes a specific QCL type (qcl-Type, whose value includes one of {typeA, typeB, typeC, typeD}, where type A includes channel large scale parameters, i.e., {average delay, delay extension, Doppler frequency shift, Doppler extension}, type B includes channel large scale parameters, i.e., {Doppler frequency shift, Doppler extension}, type C includes channel large scale parameters, i.e., {average delay, Doppler frequency shift}, and type D includes channel large scale parameters, i.e., {reception spatial parameters}), a reference signal type (e.g., csi-rs, SSB), a reference signal identifier (e.g., NZP-CSI-RS-ResourceId, SSB-Index), a cell in which the reference signal is located, and a bandwidth portion BWP (bwp-Id). Here, the reference signals in the same QCL-Info are associated with the QCL type, that is, the reference signals in one QCL-Info are the reference signals corresponding to the QCL type indicated by this QCL-Info. In addition, some aspects of determining the QCL reference signal of the downlink signal include the following aspects.

[0130] When only one TCI state is configured for a downlink signal by radio resource control (RRC) signaling, the TCI state corresponding to the downlink signal transmission is the TCI state configured by the RRC signaling, and the reference signal included in the TCI state is the QCL reference signal of the downlink signal.

[0131] When multiple TCI states are configured for a downlink signal by RRC signaling and a TCI indicating a downlink signal is not configured via DCI, the TCI state corresponding to the downlink signal transmission may be indicated via a media access control unit (MAC-CE) signaling. In one implementation, multiple TCI states are configured via RRC signaling, and one TCI codepoint is activated via MAC-CE signaling, where the TCI codepoint corresponds to one or more TCI states configured via RRC, and the TCI codepoint corresponding to the downlink signal is the TCI codepoint activated via MAC-CE. The reference signal included in the TCI state associated with the TCI codepoint is the QCL reference signal of the downlink signal.

[0132] When a TCI indicating a downlink signal is configured through the DCI by RRC signaling, the TCI codepoint corresponding to the PDSCH transmission is indicated through the TCI field in the DCI. In one implementation, multiple TCI states are configured through RRC signaling, and multiple TCI codepoints are then configured to be activated and deactivated for the TCI field in the DCI through MAC-CE signaling, where each TCI codepoint corresponds to one or multiple TCI states, and the TCI field in the DCI selects one TCI codepoint from the multiple TCI codepoints activated through the MAC-CE as the TCI codepoint corresponding to the downlink signal. The reference signal included in the TCI state associated with the TCI codepoint corresponding to the downlink signal is the QCL reference signal of the downlink signal.

[0133] Optionally, the DCI is a DCI for scheduling the downlink signal.

[0134] In the embodiments of the present disclosure, the downlink signal may be a downlink shared channel (PDSCH) signal, a downlink control channel (PDCCH) signal, an SSB, etc. In the following, for ease of description, a PDSCH signal is taken as an example in several cases.

[0135] The above transmission programs are specifically described below.

[0136] (1)SDM Program 1a The DMRS ports of the PDSCH are in two Code Division Multiplexing (CDM) groups, of which the DMRS ports of one CDM group are associated with one TCI state and the DMRS ports of the other CDM group are associated with another TCI state.

[0137] (2) FDM Program 2a A transport block (TB) of the same PDSCH transmission occasion is associated with two TCI states, each of the two TCI states is associated with a set of resources, and the resources associated with the two TCI states do not overlap in the frequency domain, where one TCI state is associated with a set of resources, which means that a DMRS port of a PDSCH is associated with this TCI state in this set of resources.

[0138] (2) FDM Program 2b The same PDSCH TB is transmitted via two PDSCH transmission occasions, each of which is associated with one TCI state, and the two PDSCH transmission occasions do not overlap in the frequency domain.

[0139] (3) TDM Program 3 The number of PDSCH transmission occasions depends on the number of TCI states included in the TCI codepoint indicated for the PDSCH. 1) When a TCI codepoint including two TCI states is indicated, the PDSCH is transmitted in one predetermined slot via two PDSCH transmission occasions, each PDSCH transmission occasion is associated with one TCI state, and the PDSCH transmission occasions associated with the two TCI states do not overlap in the time domain (TDM 3). 2) If a TCI codepoint containing one TCI state is indicated, one TB is transmitted via one PDSCH transmission occasion, and the TCI state is associated with the PDSCH transmission occasion (falling back from TDM 3 to the basic transmission program).

[0140] (4) TDM Program 4 The PDSCH is transmitted via multiple PDSCH transmission occasions. 1) When a TCI codepoint including two TCI states is indicated, the PDSCH is transmitted via multiple PDSCH transmission occasions, different PDSCH transmission occasions are transmitted in different slots, each TCI state is associated with one or more PDSCH transmission occasions, and the two TCI states are respectively associated with different PDSCH transmission occasions (TDM 4). 2) If a TCI codepoint including one TCI state is indicated, the PDSCH is transmitted via multiple PDSCH transmission occasions, where different PDSCH transmission occasions are transmitted in different slots, and every PDSCH transmission occasion is associated with that TCI state (TDM4 fallback program).

[0141] In each of the above programs, when one PDSCH transmission occasion is selectively associated with one TCI state, the DMRS port corresponding to the transmission occasion of this PDSCH is also associated with the TCI state. When one TB block of the PDSCH is selectively associated with one TCI state, the DMRS port corresponding to this TB of the PDSCH is also associated with the TCI state.

[0142] The basic transmission program means that a PDSCH is associated with only one TCI state.

[0143] In the embodiments of the present disclosure, a DMRS port is associated with one TCI state, which means that the TCI state is used to indicate the QCL information of the DMRS port. A TCI state is associated with one set of resources, which means that the TCI state is used to indicate the QCL information of the DMRS port and / or the PDSCH layer on the set of resources. A PDSCH transmission opportunity is associated with one TCI state, which means that the TCI state is used to indicate the QCL information of the PDSCH layer and / or the DMRS port of the PDSCH on the PDSCH transmission opportunity.

[0144] Optionally, using the TCI state to indicate the QCL information of a DMRS port means using the TCI state to indicate a reference signal having a QCL relationship with the DMRS port, and using the TCI state to receive the QCL information of a signal layer means using the TCI state to indicate a reference signal having a QCL relationship with the layer.

[0145] The basic transmission scheme of the PDSCH is that all DMRS ports of the PDSCH are associated with the same TCI state, and in that TCI state, all QCL types have one associated reference signal.

[0146] Also, in typical application scenarios involving high speed movement, such as high speed transmission (HST) scenarios, multiple transmission / receiption points (TRPs, which may be multiple remote radio heads (RRHs)) can simultaneously transmit downlink signals to terminal devices in a high speed moving manner. Here, channel estimation can be performed by determining large scale parameters such as Doppler frequency shifts of the channels of the downlink signals based on Quasi Co-Location (QCL) reference signals simultaneously transmitted through multiple TRPs, and determining channel estimation interpolation coefficients based on the large scale parameters.

[0147] In addition, the network device can transmit QCL information of the DMRS port of the downlink signal to the terminal, where the QCL information includes a QCL type and a reference signal associated with each QCL type. Here, one QCL type includes one or more channel large scale parameters, and the terminal can estimate these large scale parameters of the channel of the DMRS port based on these large scale parameters of the channel of the reference signal corresponding to this QCL type, so as to better perform channel estimation of the downlink signal. For convenience of explanation, if the large scale parameter A of the channel of one antenna port is estimated from the large scale parameter A of the channel of another antenna port, the two antenna ports are considered to have a QCL relationship with respect to the channel large scale parameter A. Similarly, if the large scale parameter A of the channel of one layer of one signal is estimated from the large scale parameter A of the channel of one antenna port, the layer and the antenna port are considered to have a QCL relationship with respect to the channel large scale parameter A.

[0148] Also, considering that the terminal device moves at high speed, when the positions of the TRPs are different, the paths corresponding to each TRP may come from opposite directions, so that the Doppler frequency shifts of the multiple paths are different, so that the Doppler frequency shift and Doppler extension of the downlink channel cannot be accurately obtained through one reference signal simultaneously transmitted from multiple TRPs, so that the channel estimation result is not accurate and affects the demodulation performance of the downlink signal. In order to improve the demodulation performance of the downlink signal, considering that each TRP transmits a reference signal corresponding to itself, the terminal can commonly determine the channel estimation coefficient of the downlink channel based on the multiple reference signals, thereby making it possible to better estimate the downlink channel. In such a program, the data layer and / or DMRS port of the PDSCH have a QCL (quasi-collocation) relationship with the multiple reference signals and at least one channel large-scale parameter.

[0149] Based on the above, the embodiments of the present disclosure provide an information processing method, an apparatus, a terminal, and a network device to solve the problem in the related art that a specific transmission program cannot be accurately determined when multiple types of Multi-TRP transmission programs exist in a system. Here, the information processing method, the apparatus, the terminal, and the network device are based on the same concept, and the principles by which the information processing method, the apparatus, the terminal, and the network device solve problems are similar, so that the implementations of the information processing method, the apparatus, the terminal, and the network device can be mutually referenced, and redundant explanations will be omitted.

[0150] An embodiment of the present disclosure provides an information processing method that can be applied to a terminal, and as shown in FIG. 2, includes the following steps 21 to 22.

[0151] In step 21, transmission mode related setting information is received.

[0152] In step 22, based on the transmission mode related setting information, determine whether the transmission program of the first signal is a first transmission program, where the transmission mode related setting information includes at least one of transmission mode setting information, demodulation reference signal DMRS port indication information of the first signal, time domain resource allocation TDRA indication information for the first signal, and scene indication information regarding whether the terminal is in a high-speed railway scene and / or a frequency pre-compensation scene, and in the first transmission program, a data layer of the first signal has a quasi-co-location QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or a DMRS port of the first signal has a QCL relationship with at least two reference signals for at least one channel large scale parameter.

[0153] Here, the first signal may be a signal of a first channel, the first channel including a downlink shared channel PDSCH, and / or an uplink shared channel PUSCH, and / or an uplink control channel PUCCH, and the transmission mode setting information may be obtained via radio resource control RRC signaling, and / or media access control unit MAC-CE signaling, and / or downlink control information DCI signaling.

[0154] In an embodiment of the present disclosure, "in the first transmission program, the data layer of the first signal has a quasi-co-located QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least two reference signals for at least one channel large scale parameter" may be specifically realized as follows: in the first transmission program, the data layer of the first signal has a QCL relationship with at least two reference signals for the same channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least two reference signals for the same at least one channel large scale parameter.

[0155] Regarding "having a QCL relationship with at least two reference signals regarding at least one channel large scale parameter", specifically, this can be realized as having a QCL relationship with at least two reference signals regarding the same channel large scale parameter.

[0156] Instructing that "the terminal is in a frequency pre-compensation scene" may specifically mean, but is not limited to, instructing the network device to perform downlink signal frequency pre-compensation.

[0157] In an embodiment of the present disclosure, a transmission mode related setting information is received, and whether a transmission program of a first signal is a first transmission program is determined according to the transmission mode related setting information, where the transmission mode related setting information includes at least one of transmission mode setting information, demodulation reference signal DMRS port indication information of the first signal, time domain resource allocation TDRA indication information for the first signal, and scene indication information for whether the terminal is in a high-speed railway scene and / or a frequency pre-compensation scene, and in the first transmission program, a data layer of the first signal has a quasi-co-location QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or a DMRS port of the first signal has a QCL relationship with at least one channel large scale parameter with at least two reference signals, thus realizing accurate identification of the first transmission program, and further, a specific transmission program can be accurately determined when multiple types of Multi-TRP transmission programs exist in the system, and successfully solving the problem in the related art that a specific transmission program cannot be accurately determined when multiple types of Multi-TRP transmission programs exist in the system.

[0158] In an embodiment of the present disclosure, determining whether the transmission program of the first signal is the first transmission program based on the transmission mode related setting information includes: determining a quantity of code division multiplexing CDM groups in which the DMRS port of the first signal is located and / or quasi-co-location QCL indication information of the DMRS port of the first signal based on the DMRS port indication information; and determining whether the transmission program of the first signal is the first transmission program based on the quantity and / or QCL indication information.

[0159] The "quasi-co-location QCL indication information of the DMRS port" may be specifically realized as, but is not limited to, the QCL indication information of the DMRS port of the layer of the first signal. For example, the QCL indication information of the layer of the first signal indicates the QCL information of the DMRS port. When the QCL indication information of the layer of the first signal indicates the QCL information of the DMRS port, the reference signal for determining a certain channel large scale parameter of one layer of the first signal is selectably a parameter signal for determining the channel large scale parameter of the DMRS port corresponding to the layer.

[0179] Here, "determine a reference signal having a QCL relationship with the DMRS port on a frequency characteristic channel large scale parameter according to a first rule" may be instructed by a network device or may be determined based on a predefined method or rule in a protocol. For example, when the network device indicates that the UE is in a frequency pre-compensation scene and indicates a TCI state of method 10, it determines that it is the first transmission program.

[0180] The channel large scale parameters included in the third type may specifically be {average delay, delay extension, Doppler frequency shift, Doppler extension}.

[0181] Optionally, the transmission mode related configuration information is used to instruct the terminal to determine a reference signal having a QCL relationship with the DMRS port with respect to a frequency characteristic channel large scale parameter according to a first rule; Determining a reference signal having a QCL relationship with the DMRS port with respect to a frequency characteristic channel large scale parameter according to a first rule includes: determining a target TCI state; The method includes: setting a reference signal corresponding to a QCL type including a frequency characteristic channel large scale parameter in the target TCI state as a reference signal having a QCL relationship regarding a frequency characteristic channel large scale parameter with the DMRS port.

Upon receiving the target TCI state, the terminal determines the frequency characteristic of the channel of the first signal using the reference signal corresponding to a QCL type including the frequency characteristic channel large scale parameter in the target TCI state, without determining the frequency characteristic of the channel of the first signal using another TCI state.

[0188] In an embodiment of the present disclosure, the information processing method optionally further includes receiving first indication information for indicating a target TCI state, wherein the first rule is that a UE ignores a reference signal corresponding to a QCL type including a frequency characteristic channel large scale parameter in the target TCI state, and a reference signal corresponding to a QCL type including a frequency characteristic channel large scale parameter in another TCI state is used to determine a reference signal of a frequency characteristic channel large scale parameter of a channel of a first signal.

[0190] In an embodiment of the present disclosure, the information processing method optionally further includes receiving first indication information for indicating a target TCI state, wherein the first rule is that a UE ignores a reference signal corresponding to a QCL type including a delay characteristic channel large scale parameter in the target TCI state, and a reference signal corresponding to a QCL type including a delay characteristic channel large scale parameter in another TCI state is used to determine a reference signal of a frequency characteristic channel large scale parameter of a channel of a first signal.

[0192] In the embodiment of the present disclosure, the eighth condition in this method may be used in combination with any of the above conditions, and is not limited thereto.

[0193] In each of the above schemes and their combinations, the QCL indication is selectively indicated via RRC signaling. In one implementation, if the radio resource control (RRC) signaling configures only one TCI state for the first signal, the QCL indication is the TCI state configured by the RRC signaling. The reference signal included in the TCI state associated with the TCI codepoin corresponding to the first signal is the QCL reference signal of the first signal and / or the DMRS port of the first signal.

[0194] In each of the above methods and their combinations, the QCL indication information is optionally indicated via a media access control unit (MAC-CE) signaling. In one implementation, the RRC signaling configures multiple TCI states for the first signal, and the MAC-CE signaling activates one TCI codepoint for the first signal, the TCI codepoint corresponds to one or more TCI states configured via the RRC, and the information indicated via the MAC-CE signaling is the QCL indication information. A reference signal included in the TCI state corresponding to the TCI codepoint is a QCL reference signal of the first signal and / or a DMRS port of the first signal.

[0195] In each of the above methods and combinations thereof, optionally, the QCL indication is indicated by a TCI field in a DCI that schedules the first signal. For example, the TCI of the first signal is indicated by the DCI via RRC signaling, and the QCL indication is a TCI codepoint corresponding to the first signal and is indicated by a TCI field in the DCI. As an implementation method, multiple TCI states are configured via RRC signaling, and multiple TCI codepoints are then activated and deactivated for the TCI field in the DCI via MAC-CE signaling, each TCI codepoint corresponds to one or more TCI states, and the TCI field in the DCI selects one TCI codepoint from the multiple TCI codepoints activated via MAC-CE as the TCI codepoint corresponding to the first signal. The reference signal included in the TCI state corresponding to the TCI codepoint is a QCL reference signal of the first signal and / or a DMRS port of the first signal.

[0196] For each of the above methods, in an embodiment of the present disclosure, the information processing method further includes determining a frequency of the downlink signal based on a reference signal for determining a transmission frequency of the uplink signal.

[0197] For each of the above methods, in an embodiment of the present disclosure, the information processing method further includes at least one of: determining a frequency of a downlink signal based on a reference signal having a QCL relationship for a frequency characteristic channel large scale parameter with a DMRS port of the first signal; and determining a transmission frequency of an uplink signal based on a reference signal having a QCL relationship for a frequency characteristic channel large scale parameter with a DMRS port of the first signal.

[0198] The "frequency characteristic channel large scale parameter" herein may specifically be realized as, but is not limited to, Doppler broadening and / or Doppler frequency shift.

[0199] In an embodiment of the present disclosure, the information processing method further includes: determining that the transmission program of the first signal is a third transmission program when a ninth condition is satisfied; Here, the ninth condition includes that a TDRA field of a DCI that schedules the first signal does not indicate a parameter corresponding to a second transmission program, the transmission mode configuration information is not set to a value corresponding to the first transmission program, and the number of CDM groups in which a DMRS port of the first signal is located is 2; the ninth condition further includes at least one of: the first signal is associated with two TCI states; and the DMRS port of the first signal is associated with two TCI states; The third transmission program, the second transmission program, and the first transmission program are different from each other.

[0200] The third transmission program can be specifically realized as the above-mentioned SDM program 1a, but is not limited to this.

[0201] The embodiment of the present disclosure further provides an information processing method that can be applied to a network device, as shown in FIG. 3, including the following steps 31.

[0202] In step 31, indicate whether the transmission program of the first signal is a first transmission program by sending transmission mode related setting information, where the transmission mode related setting information includes at least one of transmission mode setting information, demodulation reference signal DMRS port indication information of the first signal, time domain resource allocation TDRA indication information for the first signal, and scene indication information regarding whether the terminal is in a high-speed railway scene and / or a frequency pre-compensation scene, and in the first transmission program, the data layer of the first signal has a quasi-co-location QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least two reference signals for at least one channel large scale parameter.

[0203] Here, the first signal may be a signal of a first channel, the first channel including a downlink shared channel PDSCH, and / or an uplink shared channel PUSCH, and / or an uplink control channel PUCCH, and the transmission mode setting information may be obtained via radio resource control RRC signaling, and / or media access control unit MAC-CE signaling, and / or downlink control information DCI signaling.

[0204] In an embodiment of the present disclosure, "in the first transmission program, the data layer of the first signal has a quasi-co-located QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least two reference signals for at least one channel large scale parameter" may be specifically realized as follows: in the first transmission program, the data layer of the first signal has a QCL relationship with at least two reference signals for the same channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least two reference signals for the same at least one channel large scale parameter.

[0205] Regarding "having a QCL relationship with at least two reference signals regarding at least one channel large scale parameter", specifically, this can be realized as having a QCL relationship with at least two reference signals regarding the same channel large scale parameter.

[0206] Instructing that "the terminal is in a frequency pre-compensation scene" may specifically mean, but is not limited to, instructing the network device to perform downlink signal frequency pre-compensation.

[0207] In the embodiment of the present disclosure, the transmission mode related setting information is sent to indicate whether the transmission program of the first signal is the first transmission program, where the transmission mode related setting information includes at least one of transmission mode setting information, demodulation reference signal DMRS port indication information of the first signal, time domain resource allocation TDRA indication information for the first signal, and scene indication information for whether the terminal is in a high-speed railway scene and / or a frequency pre-compensation scene, and in the first transmission program, the data layer of the first signal has a quasi-co-location QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least one channel large scale parameter with at least two reference signals, thus realizing accurate identification of the first transmission program, and further, a specific transmission program can be accurately determined when multiple types of Multi-TRP transmission programs exist in the system, and successfully solving the problem in the related art that a specific transmission program cannot be accurately determined when multiple types of Multi-TRP transmission programs exist in the system.

[0208] In an embodiment of the present disclosure, indicating whether the transmission program of the first signal is the first transmission program by sending the transmission mode related setting information includes indicating whether the transmission program of the first signal is the first transmission program by indicating, by the DMRS port indication information, the number of code division multiplexing CDM groups in which the DMRS port of the first signal is located and / or quasi-co-location QCL indication information of the DMRS port of the first signal.

[0209] The "quasi-co-location QCL indication information of the DMRS port" may be specifically realized as, but is not limited to, the QCL indication information of the DMRS port of the layer of the first signal. For example, the QCL indication information of the layer of the first signal indicates the QCL information of the DMRS port. When the QCL indication information of the layer of the first signal indicates the QCL information of the DMRS port, the reference signal for determining a certain channel large scale parameter of one layer of the first signal is selectably a parameter signal for determining the channel large scale parameter of the DMRS port corresponding to the layer.

[0213] Regarding "the TDRA field of the DCI for scheduling the first signal does not indicate a parameter corresponding to the second transmission program," this is not a limitation on the information to be indicated, but a limitation on the first condition. Therefore, for similar points to those described below, the explanation here may be referred to, and further explanation will be omitted.

[0214] Regarding "associated with at least two TCI states", specifically, this can be realized as a transmission setting indication codepoint (TCI codepoint) indicated by a transmission setting indication field in a DCI that schedules a first signal includes at least two TCI states.

[0222] Method 7 Indicating whether the transmission program of the first signal is the first transmission program by indicating QCL type information by the QCL indication information includes indicating that the transmission program of the first signal is the first transmission program by indicating information that satisfies a fifth condition by the QCL indication information; Here, the fifth condition is that the QCL indication information indicates that the first signal is associated with at least two TCI states; the QCL indication information indicates that the DMRS port of the first signal is associated with at least two TCI states; Here, one QCL type included in one TCI state among the at least two TCI states is a first type, one QCL type included in one TCI state is a second type, all channel large-scale parameters included in the first type are delay characteristic channel large-scale parameters, and the second type includes a delay characteristic channel large-scale parameter and a frequency characteristic channel large-scale parameter.

[0223] Here, the channel large scale parameters included in the first type may be specifically, but not limited to, {average delay, delay extension} or {delay extension} or {average delay}. The channel large scale parameters included in the second type may be specifically, but not limited to, {average delay, delay extension, Doppler frequency shift, Doppler extension}.

[0224] In the embodiment of the present disclosure, there is not necessarily only one QCL type in the TCI state, and there may be a QCL-Type D (reception spatial parameters), but the same applies to other methods.

[0225] Method 8 and Method 9 Indicating whether the transmission program of the first signal is the first transmission program by indicating QCL type information by the QCL indication information includes indicating that the transmission program of the first signal is the first transmission program by indicating information satisfying a sixth condition by the QCL indication information; Here, the sixth condition is: the QCL indication indicates that the first signal is associated with at least two TCI states; the QCL indication information indicates that the DMRS port of the first signal is associated with at least two TCI states; Here, one QCL type included in one TCI state of the at least two TCI states is a first type, one QCL type included in one TCI state is a third type, all channel large scale parameters included in the first type are delay characteristic parameters, and all channel large scale parameters included in the third type are frequency characteristic parameters.

[0226] Specifically, the channel large scale parameters included in the first type may be specifically {average delay, delay extension} to correspond to method 8, and the channel large scale parameters included in the first type may be specifically {delay extension} or {average delay} to correspond to method 9, but are not limited thereto.

[0227] The channel large scale parameters included in the third type may specifically be {Doppler frequency shift, Doppler expansion}.

[0228] For methods seven to nine, in an embodiment of the present disclosure, the information processing method further includes indicating, according to the TCI state, a reference signal corresponding to a QCL type including a frequency characteristic channel large scale parameter.

[0229] Here, the "QCL type including a frequency characteristic channel large scale parameter" may be specifically realized as a QCL type including {Doppler frequency shift} and / or {Doppler extension}.

[0230] method ten Indicating whether the transmission program of the first signal is the first transmission program by indicating QCL type information by the QCL indication information includes indicating that the transmission program of the first signal is the first transmission program by indicating information satisfying a seventh condition by the QCL indication information; wherein the seventh condition includes determining a reference signal having a QCL relationship with the DMRS port in terms of a frequency characteristic channel large scale parameter according to a first rule; The seventh condition further includes: the QCL indication information indicates that the first signal is associated with at least two TCI states; the QCL indication information indicates that the DMRS port of the first signal is associated with at least two TCI states; wherein the at least two TCI states include two TCI states each satisfying that one QCL type included therein is a second type; The second type includes a delay characteristic channel large scale parameter and a frequency characteristic channel large scale parameter.

[0231] Here, "determine a reference signal having a QCL relationship with the DMRS port on a frequency characteristic channel large scale parameter according to a first rule" may be instructed by a network device or may be determined based on a predefined method or rule in a protocol. For example, when the network device indicates that the UE is in a frequency pre-compensation scene and indicates a TCI state of method 10, it determines that it is the first transmission program.

[0232] The channel large scale parameters included in the third type may specifically be {average delay, delay extension, Doppler frequency shift, Doppler extension}.

[0233] In an embodiment of the present disclosure, optionally, the information processing method further includes transmitting first indication information for indicating a target TCI state, and a reference signal corresponding to a QCL type including a frequency-characteristic channel large-scale parameter in the target TCI state is a reference signal having a QCL relationship with the DMRS port regarding the frequency-characteristic channel large-scale parameter.

[0234] Here, the first indication information is transmitted via RRC signaling, and / or MAC-CE signaling, and / or DCI signaling.

[0236] In the embodiment of the present disclosure, the eighth condition in this method may be used in combination with any of the above conditions, and is not limited thereto.

[0237] In each of the above schemes and their combinations, the QCL indication is selectively indicated via RRC signaling. In one implementation, if the radio resource control (RRC) signaling configures only one TCI state for the first signal, the QCL indication is the TCI state configured by the RRC signaling. The reference signal included in the TCI state associated with the TCI codepoin corresponding to the first signal is the QCL reference signal of the first signal and / or the DMRS port of the first signal.

[0238] In each of the above methods and their combinations, the QCL indication information is optionally indicated via a media access control unit (MAC-CE) signaling. In one implementation, the RRC signaling configures multiple TCI states for the first signal, and the MAC-CE signaling activates one TCI codepoint for the first signal, the TCI codepoint corresponds to one or more TCI states configured via the RRC, and the information indicated via the MAC-CE signaling is the QCL indication information. A reference signal included in the TCI state corresponding to the TCI codepoint is a QCL reference signal of the first signal and / or a DMRS port of the first signal.

[0239] In each of the above methods and combinations thereof, optionally, the QCL indication is indicated by a TCI field in a DCI that schedules the first signal. For example, the TCI of the first signal is indicated by the DCI via RRC signaling, and the QCL indication is a TCI codepoint corresponding to the first signal and is indicated by a TCI field in the DCI. As an implementation method, multiple TCI states are configured via RRC signaling, and multiple TCI codepoints are then activated and deactivated for the TCI field in the DCI via MAC-CE signaling, each TCI codepoint corresponds to one or more TCI states, and the TCI field in the DCI selects one TCI codepoint from the multiple TCI codepoints activated via MAC-CE as the TCI codepoint corresponding to the first signal. The reference signal included in the TCI state corresponding to the TCI codepoint is a QCL reference signal of the first signal and / or a DMRS port of the first signal.

[0240] For each of the above methods, in an embodiment of the present disclosure, the information processing method further includes indicating a reference signal for determining a transmission frequency of an uplink signal.

[0241] For each of the above methods, in an embodiment of the present disclosure, the information processing method further includes indicating a reference signal having a QCL relationship with a DMRS port of the first signal in terms of a frequency characteristic channel large scale parameter.

[0242] The "frequency characteristic channel large scale parameter" herein may specifically be realized as, but is not limited to, Doppler broadening and / or Doppler frequency shift.

[0243] In an embodiment of the present disclosure, the information processing method further includes indicating that the transmission program of the first signal is a third transmission program by indicating information that satisfies a ninth condition through the transmission mode related setting information; Here, the ninth condition includes that a TDRA field of a DCI that schedules the first signal does not indicate a parameter corresponding to a second transmission program, the transmission mode configuration information is not set to a value corresponding to the first transmission program, and the number of CDM groups in which a DMRS port of the first signal is located is two; the ninth condition further includes at least one of: the first signal is associated with two TCI states; and the DMRS port of the first signal is associated with two TCI states; The third transmission program, the second transmission program, and the first transmission program are different from each other.

[0244] The third transmission program can be specifically realized as the above-mentioned SDM program 1a, but is not limited to this.

[0245] The information processing method according to the embodiment of the present disclosure will be further described below in relation to various aspects such as a terminal and a network device. Hereinafter, the first transmission program is referred to as a transmission program of SDM 1c, and the first signal is an example of a PDSCH signal (hereinafter abbreviated as PDSCH).

[0246] In response to the above technical problems, an embodiment of the present disclosure provides an information processing method, in which the systems to which the program of the embodiment of the present disclosure is applicable include, but are not limited to, NR systems, LTE systems, 6G systems, and their evolutionary version systems.

[0247] The transmission program for SDM 1c is as follows:

[0248] The data layer and / or DMRS ports of the PDSCH have a QCL relationship with the plurality of reference signals for at least one channel large scale parameter, and optionally, specifically, all data layers and / or DMRS ports of the PDSCH have a QCL relationship with the plurality of reference signals for at least one channel large scale parameter.

[0249] Optionally, in particular, the data layer of the PDSCH and / or the DMRS port has a QCL relationship with the plurality of reference signals with respect to at least one channel large-scale parameter.

[0250] Optionally, in particular, the data layer of the PDSCH has a QCL relationship with multiple reference signals with respect to the same channel large scale parameter, and / or the DMRS port of the PDSCH has a QCL relationship with multiple reference signals with respect to the same channel large scale parameter.

[0251] Optionally, in particular, any one data layer of the PDSCH has a QCL relationship with multiple reference signals with respect to the same channel large scale parameter, and / or any one DMRS port of the PDSCH has a QCL relationship with multiple reference signals with respect to the same channel large scale parameter.

[0252] Optionally, in particular, all data layers of the PDSCH have a QCL relationship with multiple reference signals with respect to the same channel large scale parameter, and / or all DMRS ports of the PDSCH have a QCL relationship with multiple reference signals with respect to the same channel large scale parameter. For example, if the PDSCH shares two DMRS ports (DMRS Port 1 and DMRS Port 2), each of the two DMRS ports has a QCL relationship with multiple reference signals with respect to channel large scale parameter A. For example, DMRS Port 1 has a QCL relationship with reference signals RS1 and RS2 with respect to channel large scale parameter A, and DMRS Port 2 has a QCL relationship with reference signals RS1 and RS2 with respect to channel large scale parameter A. Optionally, all DMRS ports of the PDSCH have a QCL relationship with the same channel large scale parameter with the same multiple reference signals. Still taking the case where the PDSCH shares two DMRS ports (DMRS port 1 and DMRS port 2) as an example, the two DMRS ports both have a QCL relationship with reference signal RS1 and reference signal RS2 with respect to the channel large scale parameter A.

[0253] Optionally, the network device indicates to the UE a QCL relationship for a channel large scale parameter between a data layer / DMRS port of the PDSCH and a reference signal through a TCI indication, and indicates a TCI codepoint through one TCI indication, the TCI codepoint may be associated with one or more TCI states, and in each TCI state, one or more QCL types and reference signals corresponding to each QCL type are included.

[0254] Specifically, the following applies: (1) Optionally, for SDM 1c, the TCI codepoint indicated by the TCI indication information is associated with multiple TCI states, and the QCL types included in the multiple TCI states are the same or different. The data layer / DMRS port of the PDSCH has a QCL relationship for each reference signal indicated by these TCI states and the QCL type corresponding to each reference signal. Selectably, all data layer / DMRS ports of the PDSCH have a QCL relationship for each reference signal indicated by these TCI states and the QCL type corresponding to each reference signal. Selectably, any one data layer / DMRS port of the PDSCH has a QCL relationship for each reference signal indicated by these TCI states and the QCL type corresponding to each reference signal. Selectably, at least two TCI states of the multiple TCI states include one same QCL type. The data layer / DMRS port of the PDSCH has a QCL relationship for the one same QCL type for reference signals corresponding to the one same QCL type included in the at least two TCI states.

[0255] Here, the QCL types included in the multiple TCI states may be the same or different.

[0256] Selectively, the QCL types included in at least two TCI states among the plurality of TCI states correspond to at least one of the same channel large scale parameters. For example, one TCI state among the two TCI states includes a QCL type A, and the channel large scale parameters corresponding to the QCL type A are {average delay, delay extension, Doppler frequency shift, Doppler extension}, and another TCI state includes a QCL type B, and the channel large scale parameters corresponding to the QCL type B are {Doppler frequency shift, Doppler extension}, and the QCL types included in these two TCI states correspond to the Doppler frequency shift and the Doppler extension, that is, there are two of the same channel large scale parameters, so that "the QCL types included in at least two TCI states among the plurality of TCI states correspond to at least one of the same channel large scale parameters." is satisfied.

[0257] For example, one TCI state out of two TCI states includes only QCL type B, and the channel large scale parameters corresponding to QCL type B are {Doppler frequency shift, Doppler extension}, while the other TCI state includes only QCL type D, and the channel large scale parameters corresponding to QCL type D are {spatial reception parameters}. Since the QCL types included in these two TCI states correspond to different channel large scale parameters in total, this does not satisfy "QCL types included in at least two TCI states out of the multiple TCI states correspond to at least one of the same channel large scale parameters."

[0258] (2) Optionally, for SDM 1c, the TCI codepoint indicated by the TCI indication information is associated with one or more TCI states, among which a QCL type included in at least one TCI state corresponds to multiple reference signals. The data layer / DMRS port of the PDSCH has multiple reference signals corresponding to this QCL type and a QCL relationship for this QCL type. Optionally, all data layer / DMRS ports of the PDSCH have multiple reference signals corresponding to this QCL type and a QCL relationship for this QCL type. Optionally, any data layer and / or DMRS port of the PDSCH has multiple reference signals corresponding to this QCL type and a QCL relationship for this QCL type.

[0259] The program according to the embodiment of the present disclosure mainly performs SDM based on a setting of signaling (RRC signaling, media access control unit MAC-CE signaling, or downlink control information DCI) (corresponding to the above-mentioned transmission mode setting information), a setting of a DMRS port of a PDSCH (corresponding to the above-mentioned DMRS port indication information and including QCL indication information that may indicate QCL type information and / or number information of TCI states, where the setting may be information indicated by DCI signaling, for example, an antenna port indicated by a DCI scheduling the PDSCH, and where the setting may be information indicated by one signaling or a plurality of signalings, for example, a part of the information is indicated by RRC signaling and another part of the information is indicated by DCI), a time domain resource allocation TDRA indication for a PDSCH of a network device (corresponding to the above-mentioned TDRA indication information), and / or indication information of whether the UE is in a high-speed train scene and / or a frequency pre-compensation scene (corresponding to the above-mentioned scene indication information). 1c (which can also be understood as determining whether the transmission program of the first signal to be adopted is SDM 1c).

[0260] Specifically, this can be realized by determining whether it is SDM 1c using at least one of the following methods (for "associated with at least two TCI states", an example is that the corresponding TCI codepoint includes two or more TCI states; for the parameters of the second transmission program, an example is setting the number of times that the TDM 4 is repeated; for the transmission mode, an example is the repeated transmission mode; and for the signaling, an example is RRC signaling).

[0261] Method 1 (determined based on the DMRS port setting of the PDSCH and the TDRA instruction for the PDSCH) If the TDRA field of the DCI scheduling a PDSCH does not indicate that it contains a setting corresponding to the number of TDM 4 overlaps (also understood as a TDM 4 setting parameter), and the TCI codepoint corresponding to the PDSCH (and / or the DMRS ports of the PDSCH) contains two or more TCI states, and all the DMRS ports of the PDSCH are within one CDM group, then the transmission of the PDSCH is an SDM 1c transmission program.

[0262] Method 2 (based on RRC signaling settings) When an RRC parameter for indicating the duplicate transmission mode of a PDSCH (for example, the RRC parameter Repetition Scheme-r16, which is also referred to as "RepetitionScheme", hereinafter referred to as "RepetitionScheme-r16" as an example, and the duplicate transmission mode may be a multi-transmission point M-TRP transmission mode) is set to a value corresponding to SDM 1c, the transmission of the PDSCH is a transmission program of SDM 1c.

[0263] Method 3 (based on RRC signaling settings) If an RRC parameter for indicating the duplicate transmission mode of a PDSCH (e.g., the RRC parameter RepetitionScheme-r16) is set to a value corresponding to SDM 1c and the TCI codepoint corresponding to the PDSCH includes two or more TCI states, the transmission of the PDSCH is an SDM 1c transmission program.

[0264] Optionally, the UE may further determine whether it is SDM 1a according to the following manner.

[0265] If the TDRA field of the DCI scheduling the PDSCH does not indicate that it contains a setting corresponding to the number of repetitions of TDM 4, and an RRC parameter for indicating the repetition transmission mode of the PDSCH (e.g., the RRC parameter RepetitionScheme-r16) is not set to a value corresponding to SDM 1c, and the TCI codepoint corresponding to the PDSCH includes two TCI states, and the DMRS port of the PDSCH is in two CDM groups, then the transmission of the PDSCH is an SDM 1a transmission program.

[0266] Method 4 (based on RRC signaling settings and PDSCH DMRS port settings) If an RRC parameter for indicating the duplicate transmission mode of a PDSCH (e.g., the RRC parameter RepetitionScheme-r16) is set to a value corresponding to SDM 1c, and the TCI codepoint corresponding to the PDSCH includes two or more TCI states, and all DMRS ports of the PDSCH are within one CDM group, then the transmission of the PDSCH is an SDM 1c transmission program.

[0267] Method 5 (determined based on the setting of the DMRS port of the PDSCH) If the TCI codepoint corresponding to a PDSCH includes at least one TCI state that satisfies the following condition, the transmission of the PDSCH is an SDM 1c transmission program.

[0268] Condition: At least one QCL type is associated with multiple reference signals.

[0269] Method 6 (determined based on the TDRA instruction for PDSCH and the DMRS port setting for PDSCH) If the TDRA field of the DCI scheduling the PDSCH does not indicate that it contains a setting corresponding to the number of overlaps of TDM 4, and the TCI codepoint corresponding to the PDSCH contains at least one TCI state that satisfies the following conditions, the transmission of the PDSCH is an SDM 1c transmission program.

[0270] Condition: At least one QCL type is associated with multiple reference signals.

[0271] For example, TCI state 1 is: QCL_type(QCL type)1:RS(reference signal)1,RS2 QCL_type2:RS3 RS4 It is understood that at least one QCL_type corresponds to two RSs.

[0272] Method 7 (determined based on the configuration of the DMRS port of the PDSCH, specifically, using the QCL type information and the number of TCI states) When the TCI codepoint that the network device indicates for the PDSCH includes two or more TCI states, of which one QCL type included in one TCI state (understood as one of the QCL types included in the TCI state) is {average delay, delay spread} (corresponding to the above first type, the TCI state may further include other QCL types), and one QCL type included in another TCI state is {average delay, delay spread, Doppler shift, Doppler spread} (corresponding to the above second type, the TCI state may further include other QCL types), the transmission of the PDSCH is an SDM 1c transmission program.

[0273] Method 8 (Determined based on the DMRS port setting of PDSCH) If the TCI codepoint that the network device indicates for the PDSCH includes two or more TCI states, of which one QCL type included in one TCI state is {average delay, delay spread} (corresponding to the above-mentioned first type, and the TCI state may further include other QCL types), and one QCL type included in another TCI state is {Doppler shift, Doppler spread} (corresponding to the above-mentioned third type, and the TCI state may further include other QCL types), then the transmission of the PDSCH is an SDM 1c transmission program.

[0274] Method 9 (Determined based on the DMRS port setting of PDSCH) If the TCI codepoint that the network device indicates for the PDSCH includes two or more TCI states, of which one QCL type included in one TCI state is {delay spread} (corresponding to the above-mentioned first type, and the TCI state may further include other QCL types) and one QCL type included in another TCI state is {Doppler shift, Doppler spread} (corresponding to the above-mentioned third type, and the TCI state may further include other QCL types), the transmission of the PDSCH is an SDM 1c transmission program.

[0275] Method 10 (Determined based on the setting of the DMRS port of the PDSCH) If the TCI codepoint indicated by the network device for the PDSCH includes two or more TCI states, and both of the two TCI states include reference signals corresponding to QCL types {average delay, delay spread, Doppler shift, Doppler spread} (corresponding to the above-mentioned second type), and the UE determines which reference signal is used to determine which large-scale parameter of the channel of the DMRS port according to a specific rule (corresponding to the above-mentioned first rule) (corresponding to determining a reference signal having a QCL relationship with the DMRS port regarding the frequency characteristic channel large-scale parameter according to the above-mentioned first rule), the transmission of the PDSCH is a transmission program of SDM 1c. The channel large-scale parameters include a receiving spatial parameter (e.g., a receiving beam), and / or an average gain, and / or an average delay, and / or a delay extension, and / or a Doppler frequency shift, and / or a Doppler extension. The frequency large-scale parameters of the channel include a Doppler frequency shift, and / or a Doppler extension, and the delay characteristic large-scale parameters of the channel include an average delay, and / or a delay extension.

[0276] Method 11 (determining whether the UE is in a high-speed train scene and / or a frequency pre-compensation scene and based on the configuration of the DMRS port of the PDSCH) If the network equipment indicates that the UE is in a high-speed train scene and / or a frequency pre-compensation scene, and the TCI codepoint that the network equipment indicates for the PDSCH includes two or more TCI states, the transmission of the PDSCH is a transmission program of SDM 1c.

[0277] Of course, it can be determined whether the transmission program is SDM 1c only based on whether the UE is in a high-speed train scene and / or a frequency pre-compensation scene, specifically, when the network device indicates that the UE is in a high-speed train scene and / or a frequency pre-compensation scene, the transmission of the PDSCH is a transmission program of SDM 1c, which is not limited here.

[0278] In the embodiment of the present disclosure, the corresponding content of determining the downlink frequency (corresponding to the frequency of the downlink signal) or the uplink frequency (corresponding to the transmission frequency of the uplink signal) is specifically as follows:

[0279] The network equipment sends to the UE indication information indicating that the UE is in a high-speed train scene (corresponding to the above scene indication information), or indication information that the network equipment performs downlink signal frequency pre-compensation.

[0280] The UE determines, based on the indication information, a reference signal for determining a downlink carrier frequency (ie, a downlink frequency) and / or a channel estimation algorithm for the downlink signal. Here, the manner in which the UE determines a reference signal for determining a downlink carrier frequency according to the indication information includes the following manners:

[0281] Method 1 If the indication information indicates that the UE is in a high-speed train scene or indicates that the network equipment performs downlink signal frequency pre-compensation, the UE determines a downlink carrier frequency based on a reference signal for determining the Doppler frequency shift of the downlink signal.

[0282] The UE further receives TCI indication information (TCI indication information may be included in the above DMRS port indication information) sent from the network equipment to indicate the QCL type and the QCL reference signal of the downlink signal, and the TCI indication information includes one or more TCI states. If the indication information indicates that the UE is in a high-speed train scene or indicates that the network equipment performs downlink signal frequency pre-compensation, the UE determines the TCI indication information that the network equipment indicates for the downlink signal, and determines a reference signal for determining a downlink carrier frequency according to the content indicated by the TCI indication information.

[0283] Method 1-1 If the TCI indication information indicates that a CORESET (control resource set) corresponding to a PDCCH is associated with N TCI states, and only one TCI state among the N TCI states includes a reference signal for determining a Doppler frequency shift of a PDSCH, the UE determines a downlink carrier frequency based on the reference signal for determining a Doppler frequency shift of a PDSCH, where N is an integer greater than 1.

[0284] Method 1-2 When the TCI indication information indicates that the same DMRS port of a PDSCH is associated with N TCI states, and only one TCI state among the N TCI states includes a reference signal for determining a Doppler frequency shift of a PDSCH, the UE determines a reference signal of a downlink carrier frequency based on the reference signal for determining a Doppler frequency shift of a PDSCH, where N is an integer greater than 1.

[0285] Here, Scheme 1-1 and Scheme 1-2 may have an “and / or” relationship, and in the “and” relationship, the UE determines a reference signal of a downlink carrier frequency based on a reference signal for determining a Doppler frequency shift of a PDSCH as long as only one of the following conditions is satisfied: “the TCI indication information indicates that a CORESET corresponding to a PDCCH is associated with N TCI states, and only one TCI state among the N TCI states includes a reference signal for determining a Doppler frequency shift of a PDSCH” and “the TCI indication information indicates that a same DMRS port of a PDSCH is associated with N TCI states, and only one TCI state among the N TCI states includes a reference signal for determining a Doppler frequency shift of a PDSCH”.

[0286] Method 1-3 When the TCI indication information indicates that a CORESET corresponding to a PDCCH is associated with N TCI states, and multiple TCI states among the N TCI states include a reference signal for determining a Doppler frequency shift of a PDSCH, the UE determines a downlink carrier frequency based on the reference signal for determining a Doppler frequency shift of a PDSCH in a specific TCI state, where N is an integer greater than 1.

[0287] The specific TCI state may be a pre-agreed TCI state or a TCI state instructed by a network device, for example, a first TCI state, or a second TCI state.

[0288] Method 1-4 When the TCI indication information indicates that the same DMRS port of a PDSCH is associated with N TCI states, and multiple TCI states among the N TCI states include a reference signal for determining a Doppler frequency shift of a PDSCH, the UE determines a reference signal of a downlink carrier frequency based on the reference signal for determining a Doppler frequency shift of a PDSCH in a specific TCI state, where N is an integer greater than 1.

[0289] The specific TCI state may be a pre-agreed TCI state or a TCI state instructed by a network device, for example, a first TCI state, or a second TCI state.

[0290] Optionally, the UE further determines a transmission frequency of the uplink signal based on a received frequency corresponding to a reference signal for determining the downlink carrier frequency.

[0291] Optionally, the network equipment determines a frequency pre-compensation value for a downlink signal based on the uplink signal, and the network equipment can use the frequency pre-compensation value to perform frequency pre-compensation on the downlink signal and then transmit the downlink signal to the UE.

[0292] Method 2 If the indication information indicates that the UE is in a high-speed railway scene or indicates that the network equipment performs downlink signal frequency pre-compensation, the UE determines the downlink carrier frequency based on a reference signal for determining the transmission frequency of the uplink signal.

[0293] Optionally, the network device transmits to the UE an indication of a reference signal for determining a transmission frequency of an uplink signal. Optionally, the uplink signal is a reference signal of an unspecified type, and the indication of a reference signal for determining a transmission frequency of the uplink signal is an indication applied to a plurality of uplink signals. Optionally, the uplink signal is a signal of a specific type, for example, a Sounding Reference Signal (SRS).

[0294] The reference signal for determining the transmission frequency of the uplink signal is a downlink signal, and may be a CSI-RS (Channel State Information-Reference Signal), SSB (Synchronization Signal Block), DMRS, etc. If it is a CSI-RS, it may be a CSI-RS for beam management, a CSI-RS obtained by acquiring downlink CSI, a TRS (Tracking Reference Signal), etc.

[0295] Optionally, the indication information is TCI indication information, and the TCI indication information includes one or more TCI states, in which a QCL type included in one TCI state is a transmission frequency, and a reference signal corresponding to the QCL type is a downlink signal, which may be CSI-RS, SSB, DMRS, etc. If it is CSI-RS, it may be CSI-RS for beam management, CSI-RS by acquiring downlink CSI, TRS, etc.

[0296] Optionally, the UE determines a downlink carrier frequency based on a reference signal indicated by the indication information of a reference signal for determining a transmission frequency of an uplink signal. Optionally, when the indication information indicates that the UE is in a high-speed train scene or indicates that the network equipment performs downlink signal frequency pre-compensation, the UE determines a downlink carrier frequency based on a reference signal indicated by the indication information of a reference signal for determining a transmission frequency of an uplink signal.

[0297] Wherein, the manner in which the UE determines the channel estimation algorithm for the downlink signal according to the indication information includes the following manners:

[0298] Method 1 If the indication information indicates that the UE is in a high-speed train scene or indicates that the network equipment performs downlink signal frequency pre-compensation (corresponding to indicating that the UE is in a high-speed train scene or a frequency pre-compensation scene), the UE determines that any DMRS port of the downlink signal is associated with all TCI states indicated by the network equipment for the downlink signal (which may be one TCI state or multiple TCI states, and may be indicated via a TCI field in a DCI scheduling the downlink signal), and the UE performs channel estimation of the downlink signal based on the TCI state indicated by the network equipment for the downlink signal.

[0299] Specifically, there are the following methods:

[0300] Method 1-1 The network equipment instructs the UE that the downlink signal is associated with two TCI states, of which one QCL type included in one TCI state is {average delay, delay spread} and one QCL type included in another TCI state is {average delay, delay spread, Doppler shift, Doppler spread}.

[0301] The UE determines delay characteristics of a channel of the downlink signal based on a reference signal indicated by a TCI state whose QCL type is {average delay, delay spread} and a reference signal indicated by a TCI state whose QCL type is {average delay, delay spread, Doppler shift, Doppler spread}, determines Doppler characteristics of the channel of the downlink signal based on a reference signal indicated by a TCI state whose QCL type is {average delay, delay spread, Doppler shift, Doppler spread}, and performs channel estimation of the downlink signal based on the delay characteristics and Doppler characteristics.

[0302] Method 1-2 The network equipment instructs the UE that the downlink signal is associated with two TCI states, of which one QCL type included in one TCI state is {average delay, delay spread} and one QCL type included in another TCI state is {Doppler shift, Doppler spread}. The UE determines delay characteristics of the channel of the downlink signal based on a reference signal indicated by a TCI state whose QCL type is {average delay, delay spread}, determines Doppler characteristics of the channel of the downlink signal based on a reference signal indicated by a TCI state whose QCL type is {Doppler shift, Doppler spread}, and performs channel estimation of the downlink signal based on the delay characteristics and Doppler characteristics.

[0303] Method 1-3 The network equipment instructs the UE that the downlink signal is associated with two TCI states, of which one QCL type included in one TCI state is {delay spread} and one QCL type included in another TCI state is {Doppler shift, Doppler spread}.

[0304] The UE determines delay characteristics of the channel of the downlink signal based on a reference signal indicated by a TCI state whose QCL type is {delay spread}, determines Doppler characteristics of the channel of the downlink signal based on a reference signal indicated by a TCI state whose QCL type is {Doppler shift, Doppler spread}, and performs channel estimation of the downlink signal based on the delay characteristics and Doppler characteristics.

[0305] Method 1-4 The network equipment instructs the UE that the downlink signal is associated with two TCI states, both of which include {average delay, delay spread, Doppler shift, Doppler spread} of a QCL type.

[0306] The UE commonly determines delay characteristics of a downlink signal channel based on reference signals whose QCL types are {average delay, delay spread, Doppler shift, Doppler spread} in two TCI states, determines Doppler characteristics of a downlink signal channel based on a reference signal whose QCL type is {average delay, delay spread, Doppler shift, Doppler spread} in a specific TCI state, and performs channel estimation of the downlink signal based on the delay characteristics and Doppler characteristics. The specific TCI state may be a pre-agreed TCI state or a TCI state instructed by a network device, for example, the first TCI state or the second TCI state.

[0307] Method 1-5 The network equipment instructs the UE that the downlink signal is associated with two TCI states, both of which include {average delay, delay spread, Doppler shift, Doppler spread} of a QCL type.

[0308] The UE commonly determines delay characteristics of the downlink signal channel based on reference signals whose QCL types are {average delay, delay spread, Doppler shift, Doppler spread} in two TCI states, commonly determines Doppler characteristics of the downlink signal channel based on reference signals whose QCL types are {average delay, delay spread, Doppler shift, Doppler spread} in a specific TCI state, and performs channel estimation of the downlink signal based on the delay characteristics and Doppler characteristics.

[0309] Optionally, if the network equipment indicates information indicating that the UE is in a high-speed train scene, and the network equipment indicates to the UE that the downlink signal is associated with one TCI state, the UE performs channel estimation of the downlink signal using an augmentation algorithm for HST (high-speed transmission) scenes.

[0310] The following describes a program according to an embodiment of the present disclosure with reference to an example, and illustratively, the network device is a base station.

[0311] Exemplary Scheme 1 Corresponding to Scheme 1 Above Specifically, whether the transmission mode is SDM 1c is dynamically determined through DCI signaling.

[0312] In such a program, the SDM 1c transmission program further includes that all DMRS ports of the PDSCH are all in the same CDM group.

[0313] The SDM 1c determination method is as follows: If the TDRA field of the DCI scheduling the PDSCH does not indicate a setting for RepetitionNumber-r16 (one specific example of the number of repetitions of the above TDM 4), the TCI codepoint corresponding to the PDSCH includes two or more TCI states, and all the DMRS ports of the PDSCH are within one CDM group, the transmission of the PDSCH is an SDM 1c transmission program.

[0314] As an implementation example 1 based on the exemplary scheme 1, the base station instructs the UE to receive the PDSCH via DCI.

[0315] The UE determines whether the TDRA field in the DCI indicates a PDSCH-Time Domain Resource Allocation-r16 (r16 may or may not be present) setting corresponding to the Repetition Number-r16, and then determines the number of TCI states corresponding to the TCI codepoint indicated by the TCI field in the DCI and the CDM group in which the DMRS port indicated by the antenna port field in the DCI is located. If the TDRA field of the DCI scheduling the PDSCH does not indicate a setting corresponding to RepetitionNumber-r16, the number of TCI states corresponding to the above TCI codepoint is 2, and all DMRS ports indicated by the antenna port field are all within one CDM group (can be obtained from the DMRS port indication information), the UE determines that the transmission mode of the PDSCH is SDM 1c, that is, there is only one PDSCH transmission occasion, and in the time-frequency resource corresponding to the PDSCH transmission occasion, the DMRS port of the PDSCH is associated with all TCI states corresponding to the above TCI codepoint. Here, "including RepetitionNumber-r16" is one specific realization of "corresponding to RepetitionNumber-r16", and is not limited here.

[0316] The UE receives the PDSCH based on the determined transmission mode of the PDSCH.

[0317] Optionally, the UE judges each transmission program based on the following judgment conditions: The number of TCI states included in the specified TCI codepoint Number of CDM groups on a DMRS port Whether RepetitionNumber-r16 is set in the UE (Number of repeated transmissions) Whether RepetitionScheme-r16 is set in the UE (Transmission Program Settings) UE Behavior (UE operation) 1 ≧1 YES, and the TDRA field of the DCI does not indicate the setting corresponding to RepetitionNumber-r16 / NO NO Basic transmission program 1 1 YES, and the TDRA field of the DCI indicates the setting corresponding to RepetitionNumber-r16. NO TDM4 fallback mode 2 1 YES, and the TDRA field of the DCI indicates the setting corresponding to RepetitionNumber-r16 NO TDM 4 2 1 YES, and the TDRA field of the DCI does not indicate a setting corresponding to RepetitionNumber-r16 NO SDM 1c 2 2 YES, and the TDRA field of the DCI does not indicate a setting corresponding to RepetitionNumber-r16 NO SDM 1a 2 2 NO YES or NO SDM 1a 2 1 NO NO SDM 1c 2 1 NO YES and 'TDMSchemeA' FDM 2a 2 1 NO YES and 'FDMSchemeB' FDM 2b 2 1 NO YES and 'TDMSchemeA' TDM 3

[0318] Based on the above, a possible UE determines each transmission program by a flow as shown in FIG. 4, where: The UE determines the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by a 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0319] 1. If 1, the UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0320] (1) If set, this is the fallback transmission program for TDM 4. (2) If not, it is a basic transmission program.

[0321] 2. If it is greater than 1 (eg, 2), the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0322] (1) If it is 2, determine whether the TDRA in the DCI indicates a setting including the number of retransmissions corresponding to TDM 4; if it is "NO", it is SDM 1a; if it is "YES", do not perform the operation or the terminal determines that this is an error case. (2) If 1, the UE determines whether the TDRA in the DCI indicates a setting including the number of retransmissions corresponding to TDM 4; if "YES", it is TDM 4; if "NO", it determines whether a parameter (e.g., RRC parameter RepetitionScheme-r16) exists to indicate a duplicate transmission program.

[0323] 1) If not present, then SDM 1c. 2) If present, determine a specific transmission program based on the value of the parameter.

[0324] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM 3 is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3.

[0325] Another possible flow of UE determining each transmission program is as shown in FIG. 5, where: The UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission number corresponding to TDM 4 (eg RRC parameter repetitionNumber-r16).

[0326] 1. If configured, determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0327] (1)If it is 2, then TDM 4. (2) If it is 1, it is a fallback transmission program for TDM 4.

[0328] 2. If not set, determine the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0329] (1) If it is 1, it is a basic transmission program. (2) Otherwise, the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0330] 1) If it is 2, then it is SDM 1a. 2) If 1, the UE determines whether there is a parameter (eg, RRC parameter RepetitionScheme-r16) for indicating a duplicate transmission program.

[0331] If not present, it is SDM 1c. If present, a specific transmission program is determined based on the value of the parameter.

[0332] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM 3 is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3.

[0333] Also, a possible flow of a UE determining each transmission program is as shown in FIG. 6, where: The UE determines in the RRC signaling whether there is a retransmission count setting corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16) or a parameter for indicating a duplicate transmission program (e.g., RRC parameter RepetitionScheme-r16).

[0334] 1. If neither exists, determine the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0335] (1) If it is 1, it is a basic transmission program. (2) If it is 2, determine the number of CDM groups in which the DMRS port of the PDSCH is located; if it is 1, it is SDM 1c, and if it is 2, it is SDM 1a.

[0336] 2. If a retransmission count configuration corresponding to TDM 4 exists (e.g., RRC parameter repetitionNumber-r16 exists), determine whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count configuration corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0337] (1) If 'YES', determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI that schedules the PDSCH).

[0338] 1) If it is 2, then TDM 4. 2) If it is 1, it is a fallback transmission program for TDM 4.

[0339] (2) If "NO", determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0340] 1) If it is 1, it is a basic transmission program. 2) If 2, determine the number of CDM groups in which the DMRS port of the PDSCH is located; if 1, it is SDM 1c, and if 2, it is SDM 1a.

[0341] 3. If a parameter for indicating a duplicate transmission program is present, the UE determines the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0342] (1) If it is 1, it is a basic transmission program. (2) If it is greater than 1, for example 2, the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0343] 1) If it is 2, then it is SDM 1a. 2) If it is 1, determine the value of a parameter for indicating an existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16).

[0344] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3.

[0345] Exemplary Scheme 2, corresponding to Scheme 4 above In such a program, the SDM 1c transmission program further includes that all DMRS ports of the PDSCH are all in the same CDM group.

[0346] The SDM 1c indication is multiplexed with an RRC parameter for indicating the duplicated transmission mode of the PDSCH (eg, the RRC parameter RepetitionScheme-r16), i.e. adding candidate values ​​to said parameter, eg adding candidate values ​​SDMSchemeA or SDMSchemeC.

[0347] That is, the determination method of SDM 1c is as follows. If an RRC parameter for indicating the duplicate transmission mode of a PDSCH (e.g., the RRC parameter RepetitionScheme-r16) is set to a value corresponding to SDM 1c, and the TCI codepoint corresponding to the PDSCH includes two or more TCI states, and all DMRS ports of the PDSCH are within one CDM group, then the transmission of the PDSCH is an SDM 1c transmission program.

[0348] Example implementation 2 based on exemplary scheme 2 The base station instructs the UE to receive the PDSCH via DCI.

[0349] The UE determines whether a parameter for indicating a duplicated transmission mode of the PDSCH exists in the RRC signaling, and determines the number of TCI states corresponding to the TCI codepoint indicated by the TCI field in the DCI and the CDM group in which the DMRS port indicated by the antenna port field in the DCI is located. If a parameter for indicating a duplicated transmission mode of the PDSCH exists and is set to SDM 1c, the number of TCI states corresponding to the TCI codepoint is 2, and all the DMRS ports indicated by the antenna port field are all in one CDM group, the UE determines that the transmission mode of the PDSCH is SDM 1c, that is, there is only one PDSCH transmission occasion, and in the time-frequency resource corresponding to the PDSCH transmission occasion, the DMRS port of the PDSCH is associated with all the TCI states corresponding to the TCI codepoint.

[0350] The UE receives the PDSCH based on the determined transmission mode of the PDSCH.

[0351] The judgment conditions for the UE to selectively determine each transmission program are as follows: The number of TCI states included in the specified TCI codepoint Number of CDM groups on a DMRS port Whether RepetitionNumber-r16 is set in the UE (Number of repeated transmissions) Whether RepetitionScheme-r16 is set in the UE (Transmission Program Settings) UE Behavior (UE operation) 1 ≧1 YES, and the TDRA field of the DCI does not indicate the setting corresponding to RepetitionNumber-r16 / NO NO Basic transmission program 1 1 YES, and the TDRA field of the DCI indicates the setting corresponding to RepetitionNumber-r16. NO TDM4 fallback mode 2 1 YES, and the TDRA field of the DCI indicates the setting corresponding to RepetitionNumber-r16 NO TDM 4 2 2 YES, and the TDRA field of the DCI does not indicate a setting corresponding to RepetitionNumber-r16 NO SDM 1a 2 2 NO YES / NO SDM 1a 2 1 NO YES and 'TDMSchemeA' FDM 2a 2 1 NO YES and 'FDMSchemeB' FDM 2b 2 1 NO YES and 'TDMSchemeA' TDM 3 2 1 NO YES and 'SDMSchemeA' (note that it may be expressed as another value, in other words, it is the value corresponding to SDM1c) SDM 1c

[0352] Based on the above, a possible UE determines each transmission program by the flow shown in FIG. 7, where: The UE determines the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by a 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0353] 1. If 1, the UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0354] (1) If set, this is the fallback transmission program for TDM 4. (2) If not, it is a basic transmission program.

[0355] 2. If it is greater than 1 (eg, 2), the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0356] (1)If it is 2, then it is SDM 1a. (2) If the answer is 1, the UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0357] 1) If "YES", then it is TDM 4. 2) If "NO", the UE determines the value of a parameter for indicating a duplicate transmission program (eg, the RRC parameter RepetitionScheme-r16).

[0358] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3. If SDM 1c is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is SDMSchemeA), then SDM 1c is used.

[0359] Another possible flow of UE determining each transmission program is as shown in FIG. 8, where: The UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission number corresponding to TDM 4 (eg RRC parameter repetitionNumber-r16).

[0360] 1. If configured, determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0361] (1)If it is 2, then TDM 4. (2) If it is 1, it is a fallback transmission program for TDM 4.

[0362] 2. If not set, determine the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0363] (1) If it is 1, it is a basic transmission program. (2) Otherwise, the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0364] 1) If it is 2, then it is SDM 1a. 2) If it is 1, determine the value of a parameter for indicating the existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16).

[0365] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3. If SDM 1c is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is SDMSchemeA), then SDM 1c is used.

[0366] Also, a possible flow of a UE determining each transmission program is as shown in FIG. 9, where: The UE determines in the RRC signaling whether there is a configuration for the number of retransmissions corresponding to TDM 4 (e.g., in the RRC parameter repetitionNumber-r16) or a parameter for indicating a duplicate transmission program (e.g., in the RRC parameter RepetitionScheme-r16).

[0367] 1. If neither exists, it is a basic transmission program. 2. If a retransmission count configuration corresponding to TDM 4 exists (e.g., RRC parameter repetitionNumber-r16 exists), determine whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count configuration corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0368] (1) If 'YES', determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI that schedules the PDSCH).

[0369] 1) If it is 2, then TDM 4. 2) If it is 1, it is a fallback transmission program for TDM 4.

[0370] (2) If "NO", determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0371] 1) If it is 1, it is a basic transmission program. 2) If it is 2, then it is SDM 1a.

[0372] 3. If a parameter for indicating a duplicate transmission program is present, the UE determines the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0373] (1) If it is 1, it is a basic transmission program. (2) If it is greater than 1, for example 2, the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0374] 1) If 2, determine whether the value of the parameter for indicating the duplicate transmission mode corresponds to SDM 1c; if "YES", it is SDM 1c; if "NO", it is SDM 1a. 2) If it is 1, determine the value of a parameter for indicating the existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16).

[0375] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3. If SDM 1c is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is SDMSchemeA), then SDM 1c is used.

[0376] Exemplary Scheme 3 corresponding to Scheme 3 above Optionally, the SDM 1c transmission program further includes that the same TB is transmitted via one PDSCH transmission occasion, all DMRS ports of the PDSCH are associated with multiple TCI states included in the same TCI codepoint, and all DMRS ports of the PDSCH occupy the same PRB (Physical resource block). Optionally, the multiple TCI states are specifically two TCI states.

[0377] The SDM 1c indication is multiplexed with an RRC parameter for indicating the duplicated transmission mode of the PDSCH (eg, the RRC parameter RepetitionScheme-r16), i.e. adding candidate values ​​to said parameter, eg adding candidate values ​​SDMSchemeA or SDMSchemeC.

[0378] That is, the determination method of SDM 1c is as follows.

[0379] If an RRC parameter for indicating the duplicated transmission mode of a PDSCH (eg, the RRC parameter RepetitionScheme-r16) is set to a value corresponding to SDM 1c, the transmission of the PDSCH is a transmission program of SDM 1c.

[0380] Optionally, if an RRC parameter for indicating the duplicate transmission mode of a PDSCH (e.g., the RRC parameter RepetitionScheme-r16) is set to a value corresponding to SDM 1c and the TCI codepoint corresponding to the PDSCH includes two or more TCI states, the transmission of the PDSCH is an SDM 1c transmission program.

[0381] In response to the above, the UE can determine whether it is SDM 1a according to the following manner.

[0382] If the TDRA field of the DCI scheduling the PDSCH does not indicate a setting corresponding to RepetitionNumber-r16, and an RRC parameter for indicating the duplicate transmission mode of the PDSCH (e.g., the RRC parameter RepetitionScheme-r16) is not set to a value corresponding to SDM 1c, and the TCI codepoint corresponding to the PDSCH includes two TCI states, and the DMRS port of the PDSCH is in two CDM groups, then the transmission of the PDSCH is an SDM 1a transmission program.

[0383] Example implementation 3 based on exemplary scheme 3 The base station instructs the UE to receive the PDSCH via DCI.

[0384] The UE determines whether a parameter for indicating a duplicate transmission mode of the PDSCH exists in the RRC signaling, and determines the number of TCI states corresponding to the TCI codepoint indicated by the TCI field in the DCI. If a parameter for indicating a duplicate transmission mode of the PDSCH exists and is set to SDM 1c, and the number of TCI states corresponding to the TCI codepoint is 2, the UE determines that the transmission mode of the PDSCH is SDM 1c, that is, there is only one PDSCH transmission occasion, and in the time-frequency resource corresponding to the PDSCH transmission occasion, the DMRS ports of the PDSCH are associated with all TCI states corresponding to the TCI codepoint.

[0385] The UE receives the PDSCH based on the determined transmission mode of the PDSCH.

[0386] The judgment conditions for the UE to selectively determine each transmission program are as follows: The number of TCI states included in the specified TCI codepoint Number of CDM groups on a DMRS port Whether RepetitionNumber-r16 is set in the UE (Number of repeated transmissions) Whether RepetitionScheme-r16 is set in the UE (Transmission Program Settings) UE Behavior (UE operation) 1 ≧1 YES, and the TDRA field of the DCI does not indicate the setting corresponding to RepetitionNumber-r16 / NO NO Basic transmission program 1 1 YES, and the TDRA field of the DCI indicates the setting corresponding to RepetitionNumber-r16. NO TDM4 fallback mode 2 1 YES, and the TDRA field of the DCI indicates the setting corresponding to RepetitionNumber-r16 NO TDM 4 2 2 YES, and the TDRA field of the DCI does not indicate a setting corresponding to RepetitionNumber-r16 NO SDM 1a 2 2 NO YES and the value does not correspond to SDM 1c (e.g., 'SDMSchemeA') / NO SDM 1a 2 1 NO YES and 'TDMSchemeA' FDM 2a 2 1 NO YES and 'FDMSchemeB' FDM 2b 2 1 NO YES and 'TDMSchemeA' TDM 3 2 ≧1 NO YES and a value corresponding to SDM 1c (e.g., 'SDMSchemeA', but may also be a representation of another value) SDM 1c

[0387] A possible flow of a UE determining each transmission program is as shown in FIG. 10, where: The UE determines the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by a 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0388] 1. If 1, the UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0389] (1) If set, this is the fallback transmission program for TDM 4. (2) If not, it is a basic transmission program.

[0390] 2. If it is greater than 1 (eg, 2), the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0391] (1) If 2, the UE determines whether the value of a parameter for indicating a duplicate transmission program (for example, the RRC parameter RepetitionScheme-r16) corresponds to SDM 1c.

[0392] 1) If "YES", then SDM 1c. 2) "NO" or no parameter is present to indicate a duplicate transmission program, SDM 1a.

[0393] (2) If 1, the UE determines whether the TDRA in the DCI indicates a setting including the number of retransmissions corresponding to TDM 4; if "YES", it is TDM 4; if "NO", it determines the content indicated by the value of a parameter for indicating a duplicate transmission program (e.g., RRC parameter RepetitionScheme-r16).

[0394] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3. If SDM 1c is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is SDMSchemeA), then SDM 1c is used.

[0395] Another possible flow of UE determining each transmission program is as shown in FIG. 11, where: The UE determines whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission number corresponding to TDM 4 (eg RRC parameter repetitionNumber-r16).

[0396] 1. If configured, determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0397] (1)If it is 2, then TDM 4. (2) If it is 1, it is a fallback transmission program for TDM 4.

[0398] 2. If not set, determine the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0399] (1) If it is 1, it is a basic transmission program. (2) Otherwise, the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0400] 1) If the answer is 2, determine whether the value of a parameter for indicating an existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16) corresponds to SDM 1c.

[0401] If it corresponds to SDM 1, it is SDM 1c. If not present or the value does not correspond to SDM 1c, then it is SDM 1a.

[0402] 2) If it is 1, determine the value of a parameter for indicating an existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16).

[0403] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3. If SDM 1c is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is SDMSchemeA), then SDM 1c is used.

[0404] Another possible flowchart of UE determining various transmission programs is as shown in FIG. 12, where: The UE determines in the RRC signaling whether there is a retransmission count setting corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16) or a parameter for indicating a duplicate transmission program (e.g., RRC parameter RepetitionScheme-r16).

[0405] 1. If neither exists, it is a basic transmission program.

[0406] 2. If a retransmission count configuration corresponding to TDM 4 exists (e.g., RRC parameter repetitionNumber-r16 exists), determine whether the TDRA field ("Time domain resource assignment" field) in the DCI scheduling the PDSCH indicates a configuration including a retransmission count configuration corresponding to TDM 4 (e.g., RRC parameter repetitionNumber-r16).

[0407] (1) If 'YES', determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI that schedules the PDSCH).

[0408] 1) If it is 2, then TDM 4. 2) If it is 1, it is a fallback transmission program for TDM 4.

[0409] (2) If "NO", determine the quantity of TCI states included in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0410] 1) If it is 1, it is a basic transmission program. 2) If it is 2, then it is SDM 1a.

[0411] 3. If a parameter for indicating a duplicate transmission program is present, the UE determines the quantity of TCI states contained in the TCI codepoint corresponding to the PDSCH (optionally, the TCI codepoint corresponding to the PDSCH is indicated by the 'Transmission Configuration Indication' field in the DCI scheduling the PDSCH).

[0412] (1) If it is 1, it is a basic transmission program.

[0413] (2) If it is greater than 1, for example 2, the UE determines the number of CDM groups in which the DMRS ports of the PDSCH are located.

[0414] 1) If the answer is 2, determine whether the value of a parameter for indicating an existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16) corresponds to SDM 1c.

[0415] If it corresponds to SDM 1, it is SDM 1c. If not present or the value does not correspond to SDM 1c, then it is SDM 1a.

[0416] 2) If it is 1, determine the value of a parameter for indicating the existing duplicate transmission program (eg, RRC parameter RepetitionScheme-r16).

[0417] If FDM 2a is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeA), then FDM 2a. If FDM 2b is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is FDMSchemeB), then FDM 2b. If TDM3 is indicated (e.g., the value of the RRC parameter RepetitionScheme-r16 is TDMSchemeA), then it is TDM 3. If SDM 1c is indicated (eg, the value of the RRC parameter RepetitionScheme-r16 is SDMSchemeA), then SDM 1c is used.

[0418] Exemplary Scheme 4, corresponding to Schemes 5 to 9 above Based on the quantity of reference signals associated with the same QCL type in the TCI state, it is determined whether the transmission mode is SDM 1c.

[0419] Optionally, the SDM 1c transmission program further includes: the same TB is transmitted via one PDSCH transmission occasion; the DMRS ports of the PDSCH are in one or more CDM groups and occupy the same PRBs (Physical resource blocks); the DMRS ports of the PDSCH are associated with a TCI state included in an indicated TCI codepoint; and at least one QCL type of the at least one TCI state is associated with two or more reference signals.

[0420] Optionally, in the case of an SDM 1c transmission program, the TCI codepoint indicated for the PDSCH includes only one TCI state.

[0421] In this case, it is determined whether or not it is an SDM 1c program by checking the setting of the reference signal in the TCI state specified for the PDSCH.

[0422] That is, the decision method of SDM 1c is one of the following.

[0423] If the TCI codepoint corresponding to a PDSCH includes at least one TCI state that satisfies the following condition, the transmission of the PDSCH is an SDM 1c transmission program: At least one QCL type is associated with multiple reference signals.

[0424] If the TDRA field of the DCI scheduling the PDSCH does not indicate a setting corresponding to RepetitionNumber-r16 and the TCI codepoint corresponding to the PDSCH includes at least one TCI state that satisfies the following condition, the transmission of the PDSCH is an SDM 1c transmission program, and at least one QCL type is associated with multiple reference signals.

[0425] Implementation Example 4 Based on Exemplary Scheme 4 The base station instructs the UE to receive the PDSCH via DCI.

[0426] The UE determines an association relationship between the QCL type and the reference signal in the TCI state corresponding to the TCI codepoint indicated by the TCI field in the DCI. If there is at least one QCL type associated with multiple reference signals, the UE determines that the transmission mode of the PDSCH is SDM 1c, that is, there is only one PDSCH transmission occasion, and in the time-frequency resource corresponding to the PDSCH transmission occasion, the DMRS port of the PDSCH is associated with all the TCI states corresponding to the TCI codepoint.

[0427] For example, one TCI state associated with the TCI codepoint indicated by the TCI field includes the following content, i.e., {QCL_type 1: RS1,RS2}, that is, when QCL type 1 is associated with two reference signals of RS1 and RS2, the UE determines that the transmission mode of the PDSCH is SDM 1c.

[0428] The UE receives the PDSCH based on the determined transmission mode of the PDSCH.

[0429] Implementation example 5 based on exemplary scheme 4 The base station instructs the UE to receive the PDSCH via DCI.

[0430] The UE determines whether the TDRA field in the DCI indicates a PDSCH-Time Domain Resource Allocation-r16 configuration corresponding to Repetition Number-r16, and determines the association relationship between the QCL type and the reference signal in the TCI state corresponding to the TCI codepoint indicated by the TCI field in the DCI. If the TDRA field of the DCI scheduling the PDSCH does not indicate a configuration corresponding to Repetition Number-r16, and there is at least one QCL type associated with multiple reference signals, the UE determines that the transmission mode of the PDSCH is SDM 1c, that is, there is only one PDSCH transmission occasion, and in the time-frequency resource corresponding to the PDSCH transmission occasion, the DMRS port of the PDSCH is associated with all the TCI states corresponding to the TCI codepoint.

[0431] The UE receives the PDSCH based on the determined transmission mode of the PDSCH.

[0432] In this example, in each TCI state, one or more QCL types are included, and each QCL type is associated with one or more reference signals.

[0433] The DMRS port is associated with a TCI state. This means that the large-scale parameter corresponding to a certain QCL type in the TCI state of the channel transmitting the DMRS port can be estimated based on the channel of a reference signal associated with the QCL type in the transmitted TCI state.

[0434] Some typical large-scale parameters are: Includes Doppler frequency shift, Doppler spread, average delay, delay spread, and average gain.

[0435] Exemplary Scheme 6, corresponding to Schemes 5 to 9 above Method 6 is a program that determines whether the QCL type specified by the base station for the PDSCH is SDM 1c or not.

[0436] Implementation Example 6 Based on Exemplary Scheme 6 The base station transmits scheduling information of the PDSCH to the terminal, and indicates a QCL reference signal related to the PDSCH to the PDSCH through a TCI field in the DCI. If the TCI codepoint indicated by the TCI field is associated with two TCI states, and one TCI state of the two TCI states includes at least a QCL type {average delay, delay spread} (and may include one or more other QCL types), and another TCI state includes at least a QCL type {average delay, delay spread, Doppler shift, Doppler spread} (and may include one or more other QCL types), the terminal determines that the transmission of the PDSCH is a transmission program of SDM 1c.

[0437] Examples 7 and 8 This is similar to Example 6, but the QCL types correspond to methods 8 and 9, respectively, and their explanations are omitted here.

[0438] Example 9 corresponding to the above methods 10 and 11 The base station transmits scheduling information of the PDSCH to the terminal, and indicates the QCL reference signal associated with the PDSCH to the PDSCH via RRC signaling, MAC-CE signaling, or a TCI field in the DCI.

[0439] The base station instructs the UE via RRC signaling, MAC-CE signaling, or DCI signaling that the UE determines channel characteristics corresponding to a specific large-scale parameter based on a reference signal in which TCI state. Optionally, the specific large-scale parameter is a frequency-characteristic channel large-scale parameter, such as a Doppler frequency shift and / or a Doppler extension.

[0440] If the TCI codepoint indicated by the TCI field is associated with two TCI states, and both of these TCI states include at least a QCL type {average delay, delay spread, Doppler shift, Doppler spread}, the terminal determines that the PDSCH transmission is an SDM 1c transmission program.

[0441] Example 10 corresponding to the above method 11 The base station indicates to the UE whether the UE is in a high-speed train scene.

[0442] The base station transmits scheduling information of the PDSCH to the terminal, and indicates the QCL reference signal associated with the PDSCH to the PDSCH via RRC signaling, MAC-CE signaling, or a TCI field in the DCI.

[0443] When the UE receives indication information from the base station indicating that the UE is in a high-speed train scene, and the TCI codepoint indicated by the TCI field is associated with two TCI states, the terminal determines that the transmission of the PDSCH is an SDM 1c transmission program.

[0444] Example 11 corresponding to the above method 11 The base station indicates to the UE whether the base station performs frequency pre-compensation on the downlink signal.

[0445] The base station transmits scheduling information of the PDSCH to the terminal, and indicates the QCL reference signal associated with the PDSCH to the PDSCH via RRC signaling, MAC-CE signaling, or a TCI field in the DCI.

[0446] When the UE receives from the base station an indication that the base station will perform frequency pre-compensation on the downlink signal (corresponding to the above-mentioned "frequency pre-compensation scene"), and the TCI codepoint indicated by the TCI field is associated with two TCI states, the terminal determines that the transmission of the PDSCH is an SDM 1c transmission program.

[0447] As can be seen from the above, the program of the embodiment of the present disclosure relates to a method for determining SDM 1c and a flow for a UE to determine each transmission program. According to the embodiment of the present disclosure, the determination of the SDM 1c program can be accurately realized, and the distinction from other Multi-TRP programs can be realized, thereby ensuring that a specific transmission program can be accurately determined when multiple types of Multi-TRP transmission programs exist in the system.

[0449] In an embodiment of the present disclosure, a transmission mode related setting information is received, and whether a transmission program of a first signal is a first transmission program is determined based on the transmission mode related setting information, where the transmission mode related setting information includes transmission mode setting information, demodulation reference signal DMRS port indication information of the first signal, time domain resource allocation TDRA indication information for the first signal, and / or scene indication information for whether the terminal is in a high-speed railway scene and / or a frequency pre-compensation scene, and in the first transmission program, the data layer of the first signal has a quasi-co-location QCL relationship with at least two reference signals for at least one channel large scale parameter, and / or the DMRS port of the first signal has a QCL relationship with at least one channel large scale parameter with at least two reference signals, thus realizing accurate identification of the first transmission program, and further, a specific transmission program can be accurately determined when multiple types of Multi-TRP transmission programs exist in the system, and successfully solving the problem in the related art that a specific transmission program cannot be accurately determined when multiple types of Multi-TRP transmission programs exist in the system.
