[0018] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0019] In one exemplary implementation Figure 1This is a flowchart illustrating an information transmission method provided in this application. This method is applicable to scenarios where multiple communication nodes jointly transmit data to a single terminal, improving transmission efficiency. The method can be executed by the information transmission device provided in this application, which can be implemented in software and / or hardware and integrated on the first communication node.

[0020] In one embodiment, the first and second communication nodes in this application can be base stations of macro cells, base stations or transmission nodes of small cells, transmission receive points (TRPs), transmitting nodes in high-frequency communication systems, transmitting nodes in Internet of Things systems, satellites in satellite communication, etc. The terminal can be a third communication node, which can be a node, relay node, small base station, etc. in a communication system such as a user terminal (UE), mobile phone, portable device, or automobile.

[0021] The information can be Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) information, or Physical Downlink Control Channel (PDCCH) or Physical Uplink Control Channel (PUCCH) information, or downlink / uplink demodulation reference signals, or uplink signals for random access, or channel sounding reference signals (SRS) signals, or phase tracking reference signals, etc.

[0022] For high reliability and ultra-low latency communication (URLLC) transmission schemes under multiple TRPs, they can be divided into space division multiplexing (SDM), frequency division multiplexing (FDM), and time division multiplexing (TDM).

[0023] FDM can be further divided into scheme 2a and scheme 2b. The main difference between scheme 2a and scheme 2b is that scheme 2a outputs one codeword stream after the transport block is encoded, while scheme 2b outputs two codeword streams after the transport block is encoded.

[0024] Assuming the target user occupies frequency domain resources in resource blocks (RBs) from RB0 to RBN, the resource allocation method among multiple TRPs in FDM can be a continuous resource allocation method, i.e., TRP1 occupies RB0 to RBfloor(N / 2), i.e., RB layer(N / 2), and TRP2 occupies RBfloor(N / 2)+1 to RBN; or a discrete resource allocation method, i.e., TRP1 occupies RB0, RB2, RB4, ..., RBN-1, and TRP2 occupies RB1, RB3, RB5, ..., RBN.

[0025] In addition to RBs, the frequency domain resource allocation granularity of FDM can also be a precoding resource block group (PRG).

[0026] For TDM, it can be time-division within a time slot, where different TRPs occupy different symbols within a time slot, or time-division between time slots, where different TRPs occupy different time slots.

[0027] like Figure 1 As shown, this application provides a method for transmitting information, including steps S110-S120.

[0038] The method by which the first communication node determines the required resources is not limited, as long as it ensures that the terminal can effectively transmit data with each communication node.

[0039] S120. Determine the method required to send information, and instruct the terminal on the method of sending information via signaling, or predefine the method of sending information.

[0040] In one embodiment, the first communication node instructs the terminal via signaling to provide at least one of the following information: the method of sending information and the method of receiving information.

[0041] In one embodiment, the first communication node and the terminal may also predefine the method by which the terminal receives information and / or receives information. The terminal and the first communication node transmit information based on the predefined method.

In the case of joint transmission between multiple communication nodes and a terminal, defining the resources for the terminal to receive information or the method of transmitting information improves the transmission efficiency in scenarios where multiple communication nodes jointly transmit to a single terminal.

[0047] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0048] In one embodiment, the resources include at least one of the following: frequency domain resources and time domain resources.

[0049] For example, for uRLLC transmission schemes, in order to distinguish between SDM and FDM, TRP and UE can predefine rules. If the number of TCIs corresponding to the TCI state indicated by the TCI (Transmission configuration indication) field in the DCI is greater than 1, or the number of QCL RS sets included in the TCI corresponding to the TCI state is greater than 1, it indicates that multiple TRPs transmit to one UE. Then, the transmission mode is determined according to the following situations: (1) If the resource allocation mode indicated by the DCI is a discrete resource allocation mode, such as indicating that the UE occupies RB0, RB2, RB4, ..., RBN-1, then the UE can infer that the transmission scheme is FDM, and the frequency domain resources occupied by another TRP are RB1, RB3, RB5, ..., RBN; (2) If the DCI indicates that the resources occupied by the UE are in other ways, then the UE can infer that the transmission scheme is SDM.

[0050] In one embodiment, the frequency domain resource allocation method includes at least one of the following: continuous frequency domain resource allocation and discrete frequency domain resource allocation.

[0051] In one embodiment, the method of transmitting information includes at least one of the following: spatial division, frequency division, intra-slot time division, and inter-slot time division.

[0052] In one embodiment, determining the resources required for transmitting information includes at least one of the following: when the mode of transmitting information is frequency division and the number of transmission configuration indications corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource;

[0053] When the information transmission method is frequency division and the number of quasi-common reference signal sets included in the transmission configuration indication corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource;

[0054] When the information transmission method is time-division and the number of transmission configuration indications corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource;

[0055] When the information is transmitted in a time-division manner and the number of quasi-common reference signal sets included in the transmission configuration indication corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource.

[0056] If the number of TCIs corresponding to the transmission configuration indication state TCI state indicated by the transmission configuration indication field in the downlink control signaling exceeds 1, or if the number of quasi-co-bit reference signal sets included in the TCI corresponding to the TCI state exceeds 1, then the number of communication nodes communicating with the terminal exceeds 1.

[0057] The number of communication nodes that transmit data with the terminal is determined based on the number of TCIs corresponding to the TCI state or the number of quasi-co-bit reference signal sets included in the TCIs corresponding to the TCI state.

[0058] In one embodiment, the number of communication nodes that transmit data with the terminal is equal to the number of TCIs corresponding to the TCI state or the number of quasi-co-position reference signal sets included in the TCIs corresponding to the TCI state.

[0059] The first and second frequency domain resources can be frequency domain resources used for data transmission between different communication nodes and terminals. In one embodiment, the first frequency domain resource is the frequency domain resource for data transmission between a first communication node and a terminal, and the second frequency domain resource is the frequency domain resource for data transmission between a second communication node and a terminal. The number of second frequency domain resources is at least one. Different second frequency domain resources can correspond to different second communication nodes.

[0060] In one embodiment, the information transmission method further includes: determining the allocation position of the second frequency domain resource based on the difference or sum of the allocation position and the position offset value of the first frequency domain resource.

[0061] When two communication nodes transmit data to a terminal, the first frequency domain resource and the second frequency domain resource satisfy the following relationship: the allocation position of the second frequency domain resource is equal to the allocation position of the first frequency domain resource plus the position offset value or the allocation position of the first frequency domain resource minus the position offset value.

[0062] When at least two communication nodes are transmitting data with the terminal, the number of second frequency domain resources can be at least one. The allocation position of each second frequency domain resource is equal to the allocation position of the first frequency domain resource plus the position offset value of the corresponding second communication node, or the allocation position of the first frequency domain resource minus the position offset value of the corresponding second communication node. Each second communication node has its own corresponding offset value to ensure that the frequency domain positions of each second frequency domain resource and the first frequency domain resource do not overlap.

[0063] In one embodiment, the determination of the first frequency domain resource and the second frequency domain resource includes at least one of the following: determination by downlink control signaling and determination by a predefined method.

[0064] In one embodiment, when the first communication node determines the resources required to send information, it determines the first frequency domain resources and the second frequency domain resources required to send information through downlink control signaling and determines the first frequency domain resources and the second frequency domain resources required to send information through a predefined method.

[0065] For example, Figure 2 This diagram illustrates the discrete and continuous resource allocation of the FDM transmission scheme provided in this application. The resource allocation methods for FDM transmission scheme mode 2a or mode 2b are as follows: Figure 2 As shown, the first communication node TRP1 and the second communication node TRP2 jointly transmit with the terminal UE1, using either discrete resource allocation or continuous resource allocation during transmission.

[0066] For example, in the FDM transmission scheme of uRLLC, assume that the serving cell of UE1 is TRP1, and there is an ideal backhaul connection between TRP2 and TRP1. TRP1 schedules UE1 through downlink control signaling, instructing UE1 to receive downlink data from TRP1 in time slot n at frequency domain position A. Then, the first communication node can predefine the frequency domain position of UE1 receiving downlink data from TRP2 in time slot n as B, where B = A + frequency domain offset value, or B = A - frequency domain offset value, and A and B do not overlap in the frequency domain.

[0067] Alternatively, TRP1 can schedule UE1 through downlink control signaling, instructing UE1 to send uplink data to TRP1 in time slot n at frequency domain position A. Then, the first communication node can predefine the frequency domain position of UE1 sending uplink data to TRP2 in time slot n as B, where B = A + frequency domain offset value, or B = A - frequency domain offset value, and A and B do not overlap in the frequency domain.

[0068] When there are multiple UE2s, the frequency domain position of each second communication node is determined based on the frequency domain position of the first communication node and the frequency domain offset value of each corresponding second communication node.

[0069] In one embodiment, the frequency domain position of the first communication node in the first time slot is read from the downlink control signaling; the frequency domain position of the second communication node is determined based on the frequency domain position of the first communication node, wherein there is at least one second communication node, and the frequency domain positions do not overlap; the frequency domain positions of the first communication node and each of the second communication nodes are changed continuously in the next time slot or in the time slot group. The frequency domain positions of the first and second communication nodes are used to receive or transmit information.

[0070] In one embodiment, the determination of the first frequency domain resource and the second frequency domain resource includes: when the frequency domain resource for the first communication node to send information is the first frequency domain resource and the frequency domain resource for the second communication node to send information is the second frequency domain resource in the current time slot or when the current time slot is the next time slot in the time slot group, the frequency domain resources of the first communication node and the second communication node are exchanged in the next time slot or when the current time slot is the next time slot in the time slot group.

[0071] In one embodiment, a time slot group is a group formed by dividing time slots. Different time slots are divided into different groups to form different time slot groups, such as a first time slot group and a second time slot group. If the current time slot falls into the first time slot group, the first time slot group is the current time slot group.

[0072] In the current time slot or within a time slot group, the frequency domain resources of the first communication node and the second communication node are the first frequency domain resource and the second frequency domain resource, respectively. In the next time slot or the next time slot within a time slot group, the frequency domain resources of the first communication node and the second communication node are exchanged, so that the frequency domain resources of the first communication node and the second communication node are different from those in the previous time slot.

[0073] For example, there are two resource allocation methods for schemes 2a / 2b: continuous resource allocation and discrete resource allocation. These two cases will be discussed below:

[0074] (1) A fixed resource allocation method is adopted:

[0075] Assume that the serving cell of UE1 is TRP1, and there is an ideal backhaul connection between TRP2 and TRP1. TRP1 schedules UE1 via downlink control signaling, instructing UE1 to receive downlink data from TRP1 at frequency position A in time slot n, and instructing UE1 to receive downlink data from TRP2 at frequency position B in time slot n, or predefining the frequency position of UE1 receiving downlink data from TRP2 in time slot n as B, where frequency positions A and B do not overlap in the frequency domain. Therefore, in the next time slot n+1, it can be predefined that the frequency position of UE1 receiving downlink data from TRP1 is B, and the frequency position of UE1 receiving downlink data from TRP2 is A. That is, the frequency positions of UE1 receiving downlink data from TRP1 and TRP2 alternate in the time domain as the time slot changes.

[0076] When there are at least two communication nodes communicating with the terminal, the first communication node can exchange the frequency domain positions corresponding to each communication node, so that the frequency domain positions corresponding to each communication node in the current time slot are different from the frequency domain positions corresponding to each node in the previous time slot.

[0077] For example, a fixed continuous resource allocation method is used. To increase transmission robustness, the resource allocation position can be changed alternately over time. For instance, in slot n, the frequency domain position of TRP1 on Layer 0 is the upper half-bandwidth frequency domain resource; the frequency domain position of TRP2 on Layer 1 is the lower half-bandwidth frequency domain resource; in slot n+1, the frequency domain position of TRP1 on Layer 0 is the lower half-bandwidth frequency domain resource; the frequency domain position of TRP2 on Layer 1 is the upper half-bandwidth frequency domain resource.

[0078] (2) Two resource allocation methods are adopted:

[0079] If the standard adopts a continuous resource allocation method and a discrete resource allocation method, the switching between these two methods can be RRC allocation, DCI dynamic switching (associated with a certain dynamic parameter), or it can change over time. For example, continuous resource allocation method is used in slot n, and discrete resource allocation method is used in slot n+1.

[0080] The granularity of resource allocation in the time domain can be based on odd / even slots or on slot sets.

[0081] When there are two communication nodes communicating with the terminal, in the next time slot or the current time slot is the next time slot in the time slot group, the frequency domain resource for the first communication node to send the information is the second frequency domain resource, and the frequency domain resource for the second communication node to send the information is the first frequency domain resource.

[0082] In one embodiment, determining the required method for transmitting information includes: when the allocation position of the frequency domain resources indicated by the signaling satisfies a set rule, the method for transmitting information is frequency division.

[0083] The rules can be determined based on resource blocks, resource block groups, or precoded resource block groups.

[0084] In one embodiment, the setting rule includes at least one of the following: the allocation position number of the frequency domain resource is an odd-numbered resource block, an odd-numbered resource block group, an odd-numbered precoding resource block group, an even-numbered resource block, an even-numbered resource block group, and an even-numbered precoding resource block group.

[0085] In one embodiment, the information transmission method further includes: scrambling the transmitted information using a scrambling sequence, wherein the scrambling sequence is generated by a scrambling sequence generator, and the initialization value of the scrambling sequence generator is determined in a manner including at least one of the following: c init =n RNTI ·2 15 +q·2 14 +g·2 x +n ID Where x is 10, 11, 12, or 13; g ∈ {0,1} is associated with the control resource set identifier; q ∈ {0,1} is associated with the number of transmission codewords; n RNTI For temporary identification of wireless networks; n ID ∈{0,1,…,1023} or cell identifier ID.

[0086] To randomize the interference of different TRPs, different initialization values ​​can be used for different TRPs. When there are at least two communication nodes communicating with the terminal, g∈{0,1……n} is associated with the control resource set identifier; q∈{0,1……m} is associated with the control resource set identifier. The value of n is associated with the control resource set identifier, and the value of m is associated with the control resource set identifier. In one embodiment, n and m are integers.

[0087] In one embodiment, the information transmission method further includes: scrambling the transmitted information using a scrambling sequence, wherein the scrambling sequence is generated by a scrambling sequence generator, and the initialization value of the scrambling sequence generator is determined in a manner including at least one of the following: c init =n RNTI ·2 15 +q·2 14 +n ID n ID ∈{0,1,…,1023} or cell identifier ID; when at least two control resource groups are configured in the higher-level signaling, the value of q is associated with the identifier of the control resource group.

[0088] In one embodiment, the higher-layer signaling may be signaling sent from the first communication node to the terminal.

[0089] For example, if RRC is configured with two control resource sets (CORESET groups), q is related to the identifier of the control resource set (CORESET group ID), that is, q can be 0 or 1.

[0090] When there are x identifiers for the control resource sets, the value of q can be from 1 to x, where x is a positive number.

[0091] In one embodiment, the value of q includes at least one of the following: when the identifier of the control resource set is 0, the value of q corresponding to codeword 0 is 0, and the value of q corresponding to codeword 1 is 1; when the identifier of the control resource set is 0, the value of q corresponding to codeword 0 is 1, and the value of q corresponding to codeword 1 is 0; when the identifier of the control resource set is 1, the value of q corresponding to codeword 0 is 1, and the value of q corresponding to codeword 1 is 0; when the identifier of the control resource set is 1, the value of q corresponding to codeword 0 is 0, and the value of q corresponding to codeword 1 is 1.

[0092] When the identifier of the control resource set is y, the value of q corresponding to codeword 0 is 0, the value of q corresponding to codeword 1 is 1, the value of q corresponding to codeword 2 is 2, and so on, with the value of q corresponding to codeword y being y. Alternatively, the values ​​of q corresponding to codewords 0 to y can be any value from 0 to y, with each q value being different. y is a positive number.

[0093] In one embodiment, the n ID The determination method includes at least one of the following: configuring at least two n values ​​to the terminal via higher-level signaling. ID Each of these corresponds to the identifier of at least two control resource sets.

[0094] When there are at least two communication nodes communicating with the terminal, the first communication node configures at least two n nodes to the terminal via higher-layer signaling. ID n ID The value corresponds to the identifier of at least two control resource sets.

[0095] When the identifier of the control resource set is from 0 to z, n ID The value of is from 1 to z, where z is a positive number. The identifier of each control resource set group corresponds to n. ID The values ​​can be different.

[0096] When there are two communication nodes communicating with the terminal, n IDTwo can be configured, each corresponding to a different CORESET group ID.

[0097] When the identifier of the control resource set is 1, n ID It is 1 or 0; when the identifier of the control resource set is 0, n ID It can be 1 or 0.

[0098] In one embodiment, when the information is transmitted in a time-division manner, the time-domain resources include a first time-domain resource and a second time-domain resource.

[0099] The first and second time-domain resources can be time-domain resources used for data transmission between different communication nodes and terminals.

[0100] In one embodiment, the first time-domain resource is the time-domain resource for data transmission between the first communication node and the terminal, and the second time-domain resource is the time-domain resource for data transmission between the second communication node and the terminal. The number of second time-domain resources is at least one. Different second time-domain resources can correspond to different second communication nodes.

[0101] In one embodiment, the information transmission method further includes: determining the time domain symbol position of the second time domain resource based on the start symbol and symbol length of the first time domain resource.

[0102] When there are at least two second communication nodes, the position of the time-domain symbol corresponding to each second communication node can be determined based on the starting symbol and symbol length of the first time-domain resource.

[0103] In one embodiment, second time-domain resources are selected sequentially for each second transmission node after the time-domain symbol position corresponding to the first time-domain symbol. The time-domain positions of the second time-domain resources do not overlap.

[0104] In one embodiment, when the transmission mode is time-division multiplexing, the remaining symbol length is determined according to the time-domain resource allocation field in the downlink control signaling, wherein the time-domain resource allocation field indicates the symbol length and the starting symbol position; if the remaining symbol length is greater than or equal to the symbol length, the time-domain symbol position of at least one second communication node is determined according to the time-domain resource allocation field.

[0105] In one embodiment, determining the remaining symbol length based on the time-domain resource allocation field in the downlink control signaling includes: subtracting the starting symbol position and the symbol length from the number of symbols included in the time slot to obtain the remaining symbol length.

[0106] In one embodiment, determining the time-domain symbol position of at least one second communication node according to the time-domain resource allocation domain includes: adding the symbol position of the starting symbol position to the symbol position of the symbol length to obtain the ending symbol position; obtaining the target time slot indicated by the downlink control information; selecting a corresponding time-series symbol position for at least one second communication node after the ending symbol position of the target time slot, wherein the time-series symbol positions corresponding to each second communication node do not overlap, and the symbol length corresponding to each time-series symbol position is the same as the symbol length.

[0107] For example, in a TDM transmission scheme in uRLLC, assume that the serving cell of UE1 is TRP1, and there is an ideal backhaul connection between TRP2 and TRP1. TRP1 schedules UE1 via downlink control signaling, instructing UE1 to receive downlink data from TRP1 in time slot n. If the symbol length indicated by the Time domain resource assignment field in the DCI is M, and the indicated start symbol is K, then the time domain symbol positions for UE1 to receive downlink data from TRP1 are from symbol K to symbol K+M-1. When (14-KM) is greater than or equal to M (i.e., 2M<=14-K), then UE1 receives downlink data from TRP2 for M symbols from symbol positions K+M to 13 in time slot n.

[0108] This application also provides a method for receiving information. Figure 3 This is a flowchart illustrating an information receiving method provided in this application. This information receiving method is applicable to scenarios where multiple communication nodes jointly transmit data to a single terminal, thereby improving transmission efficiency. The method can be executed by the information receiving device provided in this application, which can be implemented in software and / or hardware and integrated into the terminal.

[0109] like Figure 3 As shown, this application provides a method for receiving information, including steps S310-S320.

[0110] S310. Determine the resources required to receive information, and receive information on the resources, wherein the resources are resources indicated by the signaling of the first communication node and / or the second communication node, or predefined resources.

[0111] The first communication node and the second communication node are communication nodes that communicate with the terminal. When the terminal receives a message from the second communication node, the means by which the second communication node instructs the terminal can be the same as the means by which the first communication node instructs the terminal.

[0112] S320. Determine the method required to receive information, and receive information according to the method.

[0113] The method required to receive information is either the method indicated by the signaling of the first communication node and / or the second communication node, or a predefined method.

[0114] In one embodiment, the terminal is a third communication node.

[0115] In one embodiment, the terminal determines the resources required to receive information and receives the information on said resources. The terminal determines the mode required to receive the information and receives the information according to said mode. The resources are resources indicated by signaling from a first communication node and / or a second communication node, or predefined resources; the mode is a mode indicated by signaling from the first communication node and / or the second communication node, or a predefined mode.

[0116] It should be noted that the execution order of S310 and S320 is not limited. In one embodiment, S310 is executed first, followed by S320. In another embodiment, S320 is executed first, followed by S310. In one embodiment, only S310 is executed. In another embodiment, only S320 is executed.

[0117] Furthermore, the process or method for the UE to receive downlink data in the embodiments is also applicable to the UE sending uplink data to the TRP. That is, the technical means for the terminal to determine the resources or methods required for receiving information is applicable to the terminal to determine the resources or methods required for sending information.

[0118] For example, there are two resource allocation methods for schemes 2a / 2b: continuous resource allocation and discrete resource allocation. These two cases will be discussed below:

[0119] (1) A fixed resource allocation method is adopted:

[0120] Assume that the serving cell of UE1 is TRP1, and there is an ideal backhaul connection between TRP2 and TRP1. TRP1 schedules UE1 via downlink control signaling, instructing UE1 to receive downlink data from TRP1 at frequency position A in time slot n, and instructing UE1 to receive downlink data from TRP2 at frequency position B in time slot n, or predefining the frequency position of UE1 receiving downlink data from TRP2 in time slot n as B, where frequency positions A and B do not overlap in the frequency domain. Therefore, in the next time slot n+1, it can be predefined that the frequency position of UE1 receiving downlink data from TRP1 is B, and the frequency position of UE1 receiving downlink data from TRP2 is A. That is, the frequency positions of UE1 receiving downlink data from TRP1 and TRP2 alternate in the time domain as the time slot changes.

[0121] When there are at least two communication nodes communicating with the terminal, the terminal can exchange the frequency domain positions corresponding to each communication node, so that the frequency domain positions corresponding to each communication node in the current time slot are different from the frequency domain positions corresponding to each node in the previous time slot.

[0122] For example, a fixed continuous resource allocation method is used. To increase transmission robustness, the resource allocation position can be changed alternately over time. For instance, in slot n, the frequency domain position of TRP1 on Layer 0 is the upper half-bandwidth frequency domain resource; the frequency domain position of TRP2 on Layer 1 is the lower half-bandwidth frequency domain resource; in slot n+1, the frequency domain position of TRP1 on Layer 0 is the lower half-bandwidth frequency domain resource; the frequency domain position of TRP2 on Layer 1 is the upper half-bandwidth frequency domain resource.

[0123] (2) Two resource allocation methods are adopted:

[0124] If the standard adopts a continuous resource allocation method and a discrete resource allocation method, the switching between these two methods can be RRC allocation, DCI dynamic switching (associated with a certain dynamic parameter), or it can change over time. For example, continuous resource allocation method is used in slot n, and discrete resource allocation method is used in slot n+1.

[0125] The granularity of resource allocation in the time domain can be based on odd / even slots or on slot sets.

[0126] It should be noted that for details not covered in the information receiving method section, please refer to the information sending method section; these details will not be elaborated upon here.

[0127] In one embodiment, the resources include at least one of the following: frequency domain resources and time domain resources.

[0128] For example, for uRLLC transmission schemes, in order to distinguish between SDM and FDM, TRP and UE can predefine rules. If the number of TCIs corresponding to the TCI state indicated by the TCI (Transmission configuration indication) field in the DCI is greater than 1, or the number of QCL RS sets included in the TCI corresponding to the TCI state is greater than 1, it indicates that multiple TRPs transmit to one UE. Then, the transmission mode is determined according to the following situations: (1) If the resource allocation mode indicated by the DCI is a discrete resource allocation mode, such as indicating that the UE occupies RB0, RB2, RB4, ..., RBN-1, then the UE can infer that the transmission scheme is FDM, and the frequency domain resources occupied by another TRP are RB1, RB3, RB5, ..., RBN; (2) If the DCI indicates that the resources occupied by the UE are in other ways, then the UE can infer that the transmission scheme is SDM.

[0129] In one embodiment, the frequency domain resource allocation method includes at least one of the following: continuous frequency domain resource allocation and discrete frequency domain resource allocation.

[0130] In one embodiment, the method of receiving information includes at least one of the following: spatial division, frequency division, intra-slot time division, and inter-slot time division.

[0131] In one embodiment, determining the resources required to receive information includes:

[0132] When the information receiving method is frequency division and the number of transmission configuration indications corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource.

[0133] When the information receiving method is frequency division and the number of quasi-common reference signal sets included in the transmission configuration indication corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource.

[0134] When the information is received in a time-division manner and the number of transmission configuration indications corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource;

[0135] When the information is received in a time-division manner and the number of quasi-common reference signal sets included in the transmission configuration indication corresponding to the transmission configuration indication state indicated by the transmission configuration indication field in the downlink control signaling is greater than 1, the resource is a frequency domain resource and the frequency domain resource includes at least one of the following: a first frequency domain resource and a second frequency domain resource.

[0136] For example, in the FDM transmission scheme of uRLLC, assume that the serving cell of UE1 is TRP1, and there is an ideal backhaul connection between TRP2 and TRP1. TRP1 schedules UE1 through downlink control signaling, instructing UE1 to receive downlink data from TRP1 in time slot n at frequency domain position A. Then, the first communication node can predefine the frequency domain position of UE1 receiving downlink data from TRP2 in time slot n as B, where B = A + frequency domain offset value, or B = A - frequency domain offset value, and A and B do not overlap in the frequency domain.

[0137] Alternatively, TRP1 can schedule UE1 through downlink control signaling, instructing UE1 to send uplink data to TRP1 in time slot n at frequency domain position A. Then, the first communication node can predefine the frequency domain position of UE1 sending uplink data to TRP2 in time slot n as B, where B = A + frequency domain offset value, or B = A - frequency domain offset value, and A and B do not overlap in the frequency domain.

[0138] When there are multiple UE2s, the frequency domain position of each second communication node is determined based on the frequency domain position of the first communication node and the frequency domain offset value of each corresponding second communication node.

[0139] In one embodiment, the information receiving method further includes:

[0140] The allocation position of the second frequency domain resource is determined based on the difference or sum of the allocation position and the position offset value of the first frequency domain resource.

[0141] In one embodiment, the determination of the first frequency domain resource and the second frequency domain resource includes at least one of the following:

[0142] Determined through downlink control signaling and through predefined methods.

[0143] In one embodiment, the determination of the first frequency domain resource and the second frequency domain resource includes:

[0144] In the current time slot or a time slot within a time slot group, if the frequency domain resources for the information received by the first communication node are first frequency domain resources and the frequency domain resources for the information received by the second communication node are second frequency domain resources, then in the next time slot or the next time slot within a time slot group, the frequency domain resources of the first communication node and the second communication node are exchanged.

[0145] In one embodiment, determining the method required to receive information includes:

[0146] When the allocation of frequency domain resources indicated by the signaling meets the set rules, the information is received in a frequency division manner.

[0147] In one embodiment, the set rule includes at least one of the following:

[0148] The allocation positions of the frequency domain resources are numbered as follows: odd-numbered resource blocks, odd-numbered resource block groups, odd-numbered precoding resource block groups, even-numbered resource blocks, even-numbered resource block groups, and even-numbered precoding resource block groups.

[0149] In one embodiment, the information receiving method further includes: scrambling the received information using a scrambling sequence, wherein the scrambling sequence is generated by a scrambling sequence generator, and the initialization value of the scrambling sequence generator is determined in a manner including at least one of the following: c init =n RNTI ·2 15 +q·2 14 +g·2 x +n ID Where x is 10, 11, 12, or 13; g ∈ {0,1} is associated with the control resource set identifier; q ∈ {0,1} is associated with the number of transmission codewords; n RNTI For temporary identification of wireless networks; n ID ∈{0,1,…,1023} or cell identifier ID.

[0150] In one embodiment, the information receiving method further includes: scrambling the received information using a scrambling sequence, wherein the scrambling sequence is generated by a scrambling sequence generator, and the initialization value of the scrambling sequence generator is determined in a manner including at least one of the following: c init =n RNTI ·2 15 +q·2 14 +n ID n ID ∈{0,1,…,1023} or cell identifier ID; when at least two control resource sets are configured in the higher-layer signaling, the value of q is associated with the identifier of the control resource set. In one embodiment, the value of q includes at least one of the following:

[0151] When the identifier of the control resource set is 0, the value of q corresponding to codeword 0 is 0, and the value of q corresponding to codeword 1 is 1.

[0152] When the identifier of the control resource set is 0, the value of q corresponding to codeword 0 is 1, and the value of q corresponding to codeword 1 is 0.

[0153] When the identifier of the control resource set is 1, the value of q corresponding to codeword 0 is 1, and the value of q corresponding to codeword 1 is 0.

[0154] When the identifier of the control resource set is 1, the value of q corresponding to codeword 0 is 0, and the value of q corresponding to codeword 1 is 1.

[0155] In one embodiment, the n ID The determination method includes at least one of the following: configuring at least two n through higher-level signaling. ID Each of these corresponds to the identifier of at least two control resource sets.

[0156] When the terminal uses a scrambling sequence to scramble the received information, the corresponding technical means can be found in the technical means by which the first communication node uses a scrambling sequence to scramble the sent information, which will not be elaborated here.

[0157] In one embodiment, when the information is received in a time-division manner, the time-domain resources include a first time-domain resource and a second time-domain resource.

[0158] In one embodiment, the information receiving method further includes:

[0159] The time-domain symbol position of the second time-domain resource is determined based on the starting symbol and symbol length of the first time-domain resource.

[0160] For example, in a TDM transmission scheme in uRLLC, assume that the serving cell of UE1 is TRP1, and there is an ideal backhaul connection between TRP2 and TRP1. TRP1 schedules UE1 via downlink control signaling, instructing UE1 to receive downlink data from TRP1 in time slot n. If the symbol length indicated by the Time domain resource assignment field in the DCI is M, and the indicated start symbol is K, then the time domain symbol positions for UE1 to receive downlink data from TRP1 are from symbol K to symbol K+M-1. When (14-KM) is greater than or equal to M (i.e., 2M<=14-K), then UE1 receives downlink data from TRP2 for M symbols from symbol positions K+M to 13 in time slot n.
