[0037] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0038] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specified order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited, for example, the first object can be one or more. In addition, "and" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0039] It is worth noting that the technology described in the embodiments of the present application is not limited to the Long Term Evolution (LTE) / LTE-Advanced (LTE-A) system, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA) and other systems. The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies. The following description describes a New Radio (NR) system for illustrative purposes, and NR terminology is used in most of the following descriptions, but these technologies can also be applied to applications other than NR system applications, such as the 6th generation (6 th Generation, 6G) communication system.

[0040] In order to facilitate understanding of the embodiments of the present application, the following technical points are first introduced below:

[0041] 1. About SFN transmission method:

[0042] In SFN network deployment, multiple remote radio heads (RRH) (or TRP) are connected to a baseband processing unit (BBU), so that the terminal does not need to frequently switch base stations during high-speed movement. At the same time, multiple RRHs (TRPs) send the same data to the terminal. Figure 1 .

[0043] Due to the different positional relationships between the terminal and multiple RRHs (TRPs), the transmission signals from multiple RRHs (TRPs) have different powers, delays, phases, and Doppler shifts when reaching the terminal. When the terminal is at different positions on the rails, the SFN signal transmitted to the terminal will experience completely different channel characteristics. When the delay of the SFN signal from two RRHs (TRPs) reaching the terminal is large, the SFN signal may experience severe deep attenuation in the frequency domain; when the terminal moves at high speed between the two RRHs, it will cause two Doppler frequency shifts with opposite signs in the received signal, resulting in deep attenuation in the time domain of the SFN signal. Therefore, in order to improve the receiving performance of the terminal, the network can dynamically switch the transmission mode according to the moving position of the terminal, thereby improving the receiving performance of the terminal.

[0044] 2. About Control Resource Set (CORESET) and Search Space (SS):

[0045] In the related art, the network can configure multiple CORESETs, and the configuration of CORESET includes the number of continuous symbols, frequency domain resources, precoding granularity, interleaving mode, demodulation reference signal (DMRS) mapping mode, etc. Multiple search spaces can be configured in each CORESET, and the terminal monitors in the search spaces of multiple PDCCHs. The configuration of the search space includes the aggregation level, period and offset value (determine the monitor occasion) of PDCCH monitoring, etc. At the same time, the terminal may need to monitor the physical downlink control channel (PDCCH) in multiple CORESETs.

[0046] Among them, the search space is divided into common search space (CSS) and terminal-specific search space (USS). CSS is used to transmit control information related to broadcast control channel (BCCH), paging, random access response (RAR), etc., and USS is used to transmit control information related to downlink shared channel (DL-SCH) and uplink shared channel (UL-SCH).

[0047] 3. About the Transmission Configuration Indicator (TCI) state and Quasi Co-Location (QCL):

[0048] TCI state is used to indicate the QCL reference relationship between two antenna ports.

[0049] QCL refers to the average delay, delay spread, Doppler frequency offset, Doppler spread, and spatial reception parameters of the channel experienced by the symbol on a certain antenna port, which can be inferred from another antenna port. Four different types of QCL relationships are designed in New Radio (NR) to cope with different transmission scenarios.

[0050] 1) Quasi-co-location type A (QCL-Type A), {Doppler frequency deviation, Doppler spread, average delay, delay spread};

[0051] 2) Quasi-co-location type B (QCL-Type B), {Doppler frequency shift, Doppler spread};

[0052] 3) Quasi-co-location type C (QCL-Type C), {Doppler frequency deviation, average delay};

[0053] 4) Quasi-co-location type D (QCL-TypeD), {spatial reception parameters}.

[0054] For the Physical Downlink Share Channel (PDSCH), the Radio Resource Control (RRC) configures a maximum of M (M≤128) TCI states, the Media Access Control (MAC) Control Element (CE) activates N (N≤8) TCI states from them, and the final Downlink Control Information (DCI) indicates one of the N TCI states; for PDCCH, RRC configures a maximum of L (L≤64) TCI states for each CORESET, and these L TCIstates come from the M TCI states configured by RRC for PDSCH, and the MAC CE is one of the L TCIstates activated by a CORESET.

[0055] 1) When the PDCCH is in DCI format 1_1 and TCI state is configured in the RRC parameters:

[0056] If the scheduling time interval between DCI and PDSCH is greater than or equal to the threshold (timeDurationForQCL), the QCL reference of PDSCH is the TCI state in DCI.

[0057] If the scheduling time interval between PDCCH and PDSCH is less than the threshold (timeDurationForQCL), PDSCH is consistent with the QCL reference of the CORESET with the smallest identity (ID) in the most recent debugging time slot containing the CORESET.

[0058] 2) When the DCI is in DCI format 1_0, or the RRC parameter does not configure TCIstate, then:

[0059] If the scheduling time interval between the DCI and the PDSCH is greater than or equal to a threshold (timeDurationForQCL), the QCL reference of the PDSCH is consistent with the QCL reference of the PDCCH that schedules it.

[0060] If the scheduling time interval between DCI and PDSCH is less than the threshold (timeDurationForQCL), PDSCH is consistent with the QCL reference of the CORESET with the smallest ID in the most recent debugging time slot containing the CORESET.

[0061] 4. About the Multiple Transmitting Receiving Point (MTRP) transmission mode:

[0062] In the NR related protocols, multiple MTRP transmission modes are defined, namely:

[0063] Scheme 1a (Space Division Multiplexing (SDM));

[0064] Mode 2a (Scheme 2a) (Frequency Division Multiplexing (FDM), Mode A (Scheme A));

[0065] Scheme 2b (FDM Scheme B);

[0066] Mode 3 (Scheme 3) (TDM Scheme A);

[0067] Scheme 4 (Slot-based repetition).

[0068] Among them, Scheme 2a, Scheme 2b, Scheme 3 and Scheme 4 are indicated by RRC high-level parameters respectively:

[0069] (1) Scheme 2a: The RRC parameter (RepetitionSchemeConfig-r16) is configured as FDM-TDM-r16, the parameter (repetitionScheme-r16) in FDM-TDM-r16 is configured as fdmSchemeA, the number of code division multiplexing (CDM) groups of PDSCH is 1, and the number of TCI states indicated is 2.

[0070] (2) Scheme 2b: The RRC parameter (RepetitionSchemeConfig-r16) is configured as FDM-TDM-r16, the parameter (repetitionScheme-r16) in FDM-TDM-r16 is configured as fdmSchemeB, the number of CDM groups of PDSCH is 1, and the number of TCI states indicated is 2.

[0071] (3) Scheme 3: The RRC parameter (RepetitionSchemeConfig-r16) is configured as FDM-TDM-r16, the parameter (repetitionScheme-r16) in FDM-TDM-r16 is configured as tdmSchemeA, the number of CDM groups of PDSCH is 1, and the number of TCI states indicated is 2.

[0072] (4) Scheme 4: The RRC parameter (RepetitionSchemeConfig-r16) is configured as SlotBased-r16, and the RRC parameter PDSCH-config indicates that at least one PDSCH time domain allocation list (pdsch-TimeDomainAllocationList) contains a parameter indicating RepNumR16, and the number of CDM groups of the PDSCH is 1, and the number of TCI states indicated is 2.

[0073] (5) Scheme 1: The pdsch-TimeDomainAllocationList indicated by the RRC parameter PDSCH-config does not contain any PDSCH-TimeDomainResourceAllocation parameter including the RepNumR16 parameter, and the number of CDMgroups of the PDSCH is 2, and the number of TCI states indicated is 2.

[0074] In the SFN transmission mode (such as in a high-speed rail network), the terminal may enable a specific receiving algorithm to receive information transmitted in the SFN manner, and the implementation of the specific receiving algorithm is different from the conventional STRP receiving algorithm.

[0075] When the network dynamically instructs the terminal to switch from SFN transmission mode to STRP transmission, the terminal may not be able to immediately switch the receiving algorithm from SFN transmission mode to STRP transmission mode due to the limitation of terminal capabilities; or, when the network sends PDCCH through STRP transmission mode but sends PDSCH through SFN transmission mode, the terminal will need to dynamically switch the receiving algorithm back and forth in time when receiving PDCCH and PDSCH, which poses certain challenges to the terminal.

[0076] From another perspective, if the terminal can dynamically switch the receiving algorithm in time, it may be necessary to maintain the relevant operations of the two receiving algorithms in advance in preparation for switching at any time, which will lead to increased terminal power consumption and unnecessary redundant computing overhead when dynamic switching is not required.

[0215] Wherein, in the SFN transmission mode, the terminal uses multiple TRSs as QCL reference sources for joint processing and reception.

[0216] For the relevant description of the transmission mode switching capability information, the first scheduling information, and the second scheduling information, please refer to Figure 3 and Figure 4 Relevant content in the illustrated embodiment.

[0217] The following describes the implementation methods of the present application in combination with implementation methods one to three.

[0218] Implementation method 1:

[0219] Indication method of SFN transmission mode:

[0220] 1. For PDCCH, the following methods can be used to indicate that PDCCH is transmitted in SFN transmission mode:

[0221] a) RRC parameters are configured;

[0222] b) The number of TCI states indicated in the TCI state field of the MAC CE is equal to 2;

[0223] c) A combination of the above methods.

[0224] 2. For PDSCH, the following methods can be used to indicate that PDSCH is transmitted in SFN transmission mode:

[0225] a) RRC parameters are configured;

[0226] b) The number of TCI states indicated in the DCI codepoint is equal to 2;

[0227] c) The QCL-type of the TCI state configured or indicated in the RRC, MAC CE, or DCI is {average delay, delay spread}, or {delay spread};

[0228] d) The number of TCI states associated with the PDCCH that schedules the PDSCH is equal to 2;

[0229] e) A combination of the above methods.

[0230] Implementation method 2:

[0231] 1) See Figure 6 , PDSCH1 is scheduled by PDCCH1, and PDSCH2 is scheduled by PDCCH2. The number of TCI states associated with each bit is shown in the figure. Assume that the transmission mode switching effective time reported by the terminal is T1, and the time interval between the last symbol of PDCCH2 and the first symbol of PDSCH1 is T. Then, since T>T1, the terminal has enough time to switch from the algorithm for receiving PDCCH1 to the algorithm for receiving PDSCH1. Therefore, such scheduling can be applied to terminals with limited capabilities when dynamically switching between STRP and SFN transmission modes.

[0232] 2) See Figure 7 , assuming that T2 is the time protection interval pre-agreed between the network and the terminal, since T>T2, the terminal has enough time to switch from the algorithm for receiving PDCCH1 to the algorithm for receiving PDSCH1. Therefore, such scheduling can be applied to terminals with limited capabilities when dynamically switching between STRP and SFN transmission modes.

[0233] Implementation method three:

[0234] 1) See Figure 8 , the number of TCI states indicated by the network for DCI format 1_0 through MAC CE is 2, and the time interval T between DCI format 1_0 and the PDSCH it schedules is greater than the threshold (timeDurationForQCL), where the PDSCH is configured by the network as SFN transmission mode. Since DCI format 1_0 does not carry a TCI indication, the TCI state of the PDSCH defaults to the same as the TCI state of the DCI format1_0. It should be noted that since the network indicates that the transmission mode of the PDSCH is SFN, the terminal does not expect the number of TCI states of the DCI format 1_0 that schedules the PDSCH to be 1.

[0235] 2) See Fig. 9, the PDSCH is scheduled by the PDCCH in CORESET1, and the PDSCH is configured by the network as SFN transmission mode, but because the time interval between the PDSCH and the PDCCH that schedules it is less than the threshold (timeDurationForQCL), the terminal does not have enough time to decode the DCI information from it. Therefore, the default QCL reference of the PDSCH is consistent with the QCL reference of the CORESET with the smallest ID associated with two TCI states in the most recent debugging time slot containing the CORESET, that is, CORESET2 in the figure.
