DETAILED DESCRIPTION OF THE INVENTION
[0018] The following clearly describes the technical solutions in the embodiments of the present application, in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application fall within the scope of protection of the present application.
[0019] The terms "first," "second," etc. in the specification and claims of this application distinguish between similar objects and do not describe a specified order or sequence. It should be understood that terms used in this manner are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein. Furthermore, objects distinguished by "first" and "second" generally are of the same type and do not limit the number of objects; for example, a first object may be one or more. Furthermore, the term "and" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.
[0020] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to 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 always used interchangeably, and the described techniques may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. Although the following description describes New Radio (NR) systems for illustrative purposes and uses NR terminology in most of the following description, these technologies may also be used in applications other than NR system applications, such as sixth generation (6G) systems. thThis may be applied to 6G (6th Generation) communication systems.
[0021] In order to facilitate understanding of the embodiments of the present application, the following technical points will be first introduced below.
[0022] 1. SFN transmission method: In an SFN network deployment, multiple remote radio heads (RRHs) (also called TRPs) are connected to a single baseband processing unit (BBU). In this way, a terminal does not need to frequently switch base stations while moving at high speed. Also, referring to Figure 1, multiple RRHs (TRPs) transmit the same data to a terminal.
[0023] Because the locational relationship between the terminal and multiple remote radio receptacles (TRPs) varies, the power, delay, phase, and Doppler shift of the transmission signals from the multiple remote radio receptacles (TRPs) when they reach the terminal are different. When the terminal is located at different positions on the railway, the SFN signals transmitted to the terminal experience completely different channel characteristics. If the delay between the SFN signals from the two remote radio receptacles (TRPs) when they reach the terminal is relatively large, the SFN signals may experience severe attenuation in the frequency domain. When the terminal is moving quickly between the two remote radio receptacles (RRHs), the presence of two Doppler frequency offsets with opposite symbols in the received signal causes severe attenuation in the time domain of the SFN signals. Therefore, to improve the terminal's reception performance, the network can dynamically switch transmission modes based on the terminal's movement position to improve the terminal's reception performance.
[0024] 2. Control Resource Set (CORESET) and Search Space (SS): In related technology, a network can configure multiple CORESETs, and the configuration of a CORESET includes the number of consecutive symbols, frequency domain resources, precoding granularity, interleaving scheme, and demodulation reference signal (DMRS) mapping scheme. Multiple search spaces can also be configured in each CORESET, and a terminal monitors in multiple PDCCH search spaces. The configuration of the search space includes an aggregation level, period, and offset value (which determine monitoring occasions) for PDCCH monitoring. At the same time, a terminal may need to perform physical downlink control channel (PDCCH) monitoring in multiple CORESETs.
[0025] Here, the search space is divided into a common search space (CSS) and a UE-specific search space (USS). The CSS is used to transmit control information related to a Broadcast Control Channel (BCCH), paging, a Random Access Response (RAR), etc., and the USS is used to transmit control information related to a Downlink Shared Channel (DL-SCH), an Uplink Shared Channel (UL-SCH), etc.
[0026] 3. Transmission configuration indicator (TCI) states and Quasi Co-Location (QCL): The TCI state is used to indicate the QCL reference relationship between the two antenna ports.
[0027] QCL means that the channel average delay, delay spread, Doppler frequency offset, Doppler spread, and spatial reception parameters experienced by a symbol on one antenna port can be estimated by another antenna port. In New Radio (NR), four different types of QCL relationships have been designed to accommodate different transmission scenarios.
[0028] 1) Quasi-Collocation Type A (QCL-TypeA), {Doppler frequency offset, Doppler extension, mean delay, delay extension}, 2) Quasi-Collocation Type B (QCL-TypeB), {Doppler frequency offset, Doppler extension}, 3) Quasi-Collocation Type C (QCL-TypeC), {Doppler frequency offset, average delay}, 4) Quasi-Collocation Type D (QCL-TypeD), {spatial receiving parameters}.
[0029] For the Physical Downlink Share Channel (PDSCH), Radio Resource Control (RRC) configuration configures up to M (M≦128) TCI states, from which a media access control (MAC) control element (CE) activates N (N≦8) TCI states, and finally, Downlink Control Information (DCI) indicates one of the N TCI states. For the PDCCH, RRC configures up to L (L≦64) TCI states for each CORESET, and these L TCI states are derived from one of the L TCI states activated by a MAC CE for a CORESET among the M TCI states configured by RRC for the PDSCH.
[0030] 1) When the PDCCH is DCI format 1_1 (DCI format 1_1) and the TCI state is configured in the RRC parameters, If the scheduling time interval between DCI and PDSCH is equal to or greater than a threshold (timeDurationForQCL), the QCL reference of the PDSCH is the TCI state in the DCI; If the scheduling time interval between the PDCCH and the PDSCH is smaller than a threshold (timeDurationForQCL), the PDSCH matches the QCL reference of the CORESET with the smallest identifier (Identity, ID) in the closest debug slot containing the CORESET.
[0031] 2) If the DCI is DCI format 1_0, or if the TCI state is not configured in the RRC parameters, If the scheduling time interval between the DCI and the PDSCH is equal to or greater than a threshold (timeDurationForQCL), the QCL reference of the PDSCH matches the QCL reference of the PDCCH that schedules it; If the scheduling time interval between DCI and PDSCH is smaller than a threshold (timeDurationForQCL), the PDSCH matches the QCL reference of the CORESET with the smallest ID in the closest debug slot containing the CORESET.
[0032] 4. About Multi-TRP (Multiple Transmitting Receiving Point, MTRP) transmission mode: Various MTRP transmission modes are defined in NR related protocols, each of which: Mode 1a (Scheme 1a) (Space Division Multiplexing (SDM)), Mode 2a (Scheme 2a) (Frequency Division Multiplexing, FDM, Mode A (Scheme A)), Mode 2b (Scheme 2b) (FDM Mode B (Scheme B)), Mode 3 (Scheme 3) (TDM Scheme A), Mode 4 (Scheme 4) (Slot-based repetition).
[0033] Here, Scheme 2a, Scheme 2b, Scheme 3 and Scheme 4 are each indicated by an RRC upper layer parameter.
[0034] (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 the PDSCH is 1, and the number of indicated TCI states is 2.
[0035] (2) Scheme 2b: The RRC parameters (RepetitionSchemeConfig-r16) are configured as FDM-TDM-r16, the parameters (repetitionScheme-r16) in FDM-TDM-r16 are configured as fdmSchemeB, the number of CDM groups in the PDSCH is 1, and the number of TCI states indicated is 2.
[0036] (3) Scheme 3: The RRC parameters (RepetitionSchemeConfig-r16) are configured as FDM-TDM-r16, the parameters (repetitionScheme-r16) in FDM-TDM-r16 are configured as tdmSchemeA, the number of CDM groups in the PDSCH is 1, and the number of TCI states indicated is 2.
[0037] (4) Scheme 4: The RRC parameter (RepetitionSchemeConfig-r16) is configured as SlotBased-r16, the RRC parameter PDSCH-config indicates that at least one PDSCH time domain resource allocation (PDSCH-TimeDomainResourceAllocation) in the PDSCH time domain allocation list (pdsch-TimeDomainAllocationList) includes a parameter representing RepNumR16, the number of CDM groups in the PDSCH is 1, and the number of indicated TCI states is 2.
[0038] (5) Scheme 1: In the pdsch-TimeDomainAllocationList indicated by the RRC parameter PDSCH-config, no PDSCH-TimeDomainResourceAllocation includes the RepNumR16 parameter, the number of CDM groups in the PDSCH is 2, and the number of indicated TCI states is 2.
[0039] In the SFN transmission mode (e.g., in a high-speed rail network), the terminal may turn on a specific receiving algorithm to receive information transmitted in the SFN mode, and the implementation of the specific receiving algorithm is different from the general STRP receiving algorithm.
[0040] When the network dynamically instructs the terminal to switch from SFN transmission mode to STRP transmission, due to limitations in the terminal's capabilities, the terminal may not be able to dynamically switch the receiving algorithm from SFN transmission mode to STRP transmission mode immediately; or, when the network transmits the PDCCH in STRP transmission mode but transmits the PDSCH in SFN transmission mode, the terminal needs to repeatedly and dynamically switch the receiving algorithm in a timely manner when receiving the PDCCH and PDSCH, which is a challenge for the terminal.
[0041] From another perspective, if the terminal can dynamically switch the receiving algorithm in a timely manner, it may be necessary to simultaneously maintain the related operations of two sets of receiving algorithms in advance so that they can be switched at any time, which will increase the terminal power consumption and incur unnecessary and redundant calculation overhead when dynamic switching is not required.
[0042] 2 shows a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 21 and a network side device 22. Here, the terminal 21 may be referred to as a terminal device or user equipment (UE), and may be a terminal side device such as a mobile phone, a tablet personal computer (PDA), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a palmtop computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), a wearable device, a vehicle-mounted equipment (VUE), a pedestrian-mounted equipment (PUE), etc., and wearable devices include a smart watch, a bracelet, earphones, glasses, etc. It should be noted that the embodiments of the present application do not limit the specific type of the terminal 21.
[0043] The network side device 22 may be a base station or a core network, where the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP), a radio access network node, or any other suitable term in the art, and the base station is not limited to the specified technical term as long as the same technical effect is achieved. It should be noted that the embodiments of this application only take base stations in an NR system as examples, and do not limit the specific type of base station.
[0044] The following describes in detail the scheduling method, apparatus, device and readable storage medium according to the embodiments of the present application through several embodiments and their application scenarios in conjunction with the drawings.
[0045] Referring to FIG. 3, the present application provides a scheduling method, the execution body of which may be a terminal, and the specific steps include step 301.
[0046] Step 301: A terminal receives first scheduling information and / or second scheduling information; Here, the first scheduling information is used to schedule the terminal when the terminal reports transmission mode switching capability information, where the transmission mode switching is switching between the SFN transmission mode and another transmission mode, and the second scheduling information is used to schedule the terminal when a network side device configures the SFN transmission mode.
[0047] Here, in the SFN transmission mode, the terminal performs cooperative reception using multiple Tracking Reference Signals (TRS) (for example, two or more TRSs) as QCL reference sources.

[0054] (3) CORESET0 is used for scheduling common information.
[0055] Here, the common information may include one or more of cell broadcast information, groupcast information, and the like.
[0056] In one embodiment of the present application, the time interval information between the first PDCCH and the first PDSCH, or between the first PDCCH and the second PDCCH, or between the first PDSCH and the second PDSCH satisfies one or more of the following:

[0064] (2) When a PDSCH is associated with two TCI states and the PDCCH that schedules the PDSCH is associated with only one TCI state, the DCI in the PDCCH carries TCI indication information, and the TCI indication information includes two TCI states. For example, when a first PDSCH is associated with two TCI states and the first PDCCH that schedules the first PDSCH is associated with only one TCI state, the DCI in the first PDCCH carries TCI indication information, and the TCI indication information includes two TCI states; For example, if a second PDSCH is associated with two TCI states and the second PDCCH that schedules the second PDSCH is associated with only one TCI state, the DCI in the second PDCCH carries TCI indication information, and the TCI indication information includes two TCI states.
[0065] It should be noted that if the PDSCH is associated with two TCI states and the PDCCH that schedules the PDSCH is associated with only one TCI state, the terminal does not want the PDCCH to be scheduled in DCI format 1_0.
[0066] (3) When a PDSCH is associated with two TCI states and the scheduling time interval between the PDCCH that schedules the PDSCH and the PDSCH is less than a threshold (timeDurationForQCL), the CORESET with the smallest ID in the debug slot including the CORESET closest to the PDSCH is associated with two TCI states; Here, the type of the PDSCH includes, but is not limited to, a terminal-dedicated type or other types, and the type of the PDCCH includes, but is not limited to, a terminal-dedicated type or other types.

[0103] For related descriptions regarding the transmission mode switching capability information, the first scheduling information, and the second scheduling information, please refer to the related contents in the embodiments shown in FIGS.
[0104] Hereinafter, the embodiments of the present application will be introduced by combining the first to third embodiments.
[0105] Embodiment 1: SFN transmission mode indication method: 1. For PDCCH, a) configuring RRC parameters; b) the number of TCI states indicated in the TCI state field of the MAC CE is equal to 2; and c) A combination of the above methods may be employed to instruct the PDCCH to transmit in SFN transmission mode.
[0106] 2. For PDSCH, a) configuring RRC parameters; b) the number of TCI states indicated in the DCI codepoint is equal to 2; and c) The QCL-type of the TCI state configured or indicated to the RRC, MAC CE, and DCI is {average delay, delay extension} or {delay extension}; d) the number of TCI states associated with the PDCCH scheduling the PDSCH is equal to 2; e) A combination of the above methods may be employed to instruct the PDSCH to transmit in SFN transmission mode.
[0107] Embodiment 2: 1) Referring to Figure 6, PDSCH1 is scheduled by PDCCH1, and PDSCH2 is scheduled by PDCCH2, and the number of TCI states associated with each bit is as shown in the figure. Assume that the transmission mode switching activation 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. 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 is applicable to terminals with limited capabilities when dynamically switching between STRP and SFN transmission modes.
[0108] 2) Referring to Figure 7, if T2 is a time protection interval pre-agreed between the network and the terminal, T>T2, so the terminal has enough time to switch from an algorithm for receiving PDCCH1 to an algorithm for receiving PDSCH1. Therefore, such scheduling may be used for terminals with limited capabilities when dynamically switching between STRP and SFN transmission modes.
[0109] Embodiment 3: 1) Referring to Figure 8, the number of TCI states indicated by the network by the MAC CE for DCI format 1_0 is 2, and the time interval T between DCI format 1_0 and the PDSCH scheduled thereby is greater than a threshold (timeDurationForQCL), where the PDSCH is configured by the network in SFN transmission mode. Because no TCI indication is carried in DCI format 1_0, the TCI state of the PDSCH is consistent with the TCI state of this DCI format 1_0 by default. It should be noted that because the network indicates that the transmission mode of the PDSCH is SFN, the terminal does not want the number of TCI states of DCI format 1_0 scheduling the PDSCH to be 1.
[0110] 9, a PDSCH is scheduled by a PDCCH in CORESET1, and the PDSCH is configured in SFN transmission mode by the network. However, since the time interval between the PDSCH and the PDCCH that schedules it is less than a threshold (timeDurationForQCL), the UE does not have enough time to decode DCI information therefrom. Therefore, the default QCL reference of the PDSCH matches the QCL reference of the CORESET with the smallest ID associated with two TCI states in the debug slot containing the nearest CORESET, i.e., CORESET2 in the figure.
