The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Long Term Evolution (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, a Universal Mobile Telecommunications System (UMTS), a fifth generation (5th generation, 5G) system, or a New Radio (NR).

It should be understood that the network device in the communication system may be any device with wireless transceiving function or a chip disposed on the device, and the device includes but is not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (Node B, NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home evolved Node B, or Home Node B, HNB), BaseBand Unit (Base band Unit, BBU), Access Point (AP) in Wireless Fidelity (WIFI) system, etc., and may also be 5G, such as NR, gbb in system, or Transmission Point (TRP or TP), one or a group of antennas (including multiple antennas, NB, or a panel of Transmission points, such as a Network Node, or a BaseBand Node B, etc.), or a Distributed Unit (DU), etc.

In some deployments, the gNB may include a Centralized Unit (CU) and a DU. The gNB may also include a Radio Unit (RU). The CU implements part of the function of the gNB, and the DU implements part of the function of the gNB, for example, the CU implements Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) layers, and the DU implements Radio Link Control (RLC), Medium Access Control (MAC) and Physical (PHY) layers. Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PHCP layer signaling, may also be considered to be transmitted by the DU or by the DU + RU under this architecture. It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.

It should also be understood that terminal equipment in the communication system may also be referred to as User Equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or user device. The terminal device in the embodiment of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a wireless terminal in remote medical treatment (remote medical), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), and the like. The embodiments of the present application do not limit the application scenarios.

To facilitate understanding of the embodiments of the present application, a brief description of several terms referred to in the present application will be given first.

1. Transmission configuration indication status (TCI state): the TCI state is used to indicate a quasi co-location (QCL) relationship of a channel large-scale parameter of a data transmission process and one or two downlink reference signals. Therefore, the terminal can obtain the indication information of the large-scale parameter relationship of the channel of the received signal based on the TCI state, and then demodulate the data carried by the signal based on channel estimation. An index (servececellindex) of a serving cell, a bandwidth part (BWP) Identifier (ID), and a reference signal resource identifier (rs ID) may be included in each TCI state. The reference signal resource identifier may be at least one of the following: non-zero power (NZP) CSI-RS reference signal resource identification (NZP-CSI-RS-resource id), non-zero power CSI-RS reference signal resource set identification (NZP-CSI-RS-resource eSetId), or SSB Index (SSB-Index). Different TCI states in the following expression correspond to different TRPs.

2. Sounding reference Signal Resource Index (SRI): a channel Sounding Reference Signal (SRS) resource indication. The resource identifier used for indicating the SRS may be used as indication information referred to when the UE transmits a Physical Uplink Shared Channel (PUSCH).

3. Quasi co-localized (QCL): QCL relationships are used to indicate that multiple resources have one or more identical or similar communication characteristics. For example, if two antenna ports have a quasi co-location relationship, the large scale characteristics of the channel carrying a signal on one port can be inferred from the large scale characteristics of the channel carrying a signal on the other port. The signals corresponding to the antenna ports having the QCL relationship have the same parameters, or the parameters of one antenna port may be used to determine the parameters of another antenna port having the QCL relationship with the antenna port, or two antenna ports have the same parameters, or the parameter difference between the two antenna ports is smaller than a certain threshold. Wherein the parameters may include one or more of the following channel large-scale parameters: delay spread (delay spread), Doppler spread (Doppler spread), Doppler shift (Doppler shift), average delay (average delay), average gain, spatial Rx parameters. The spatial receiving parameter may include one or more of an Angle of arrival (AOA), a main Angle of arrival (Dominant AOA), an Average Angle of arrival (Average AOA), an Angle of Arrival (AOD), a channel correlation matrix, a power Angle spread spectrum of the Angle of arrival, an Average trigger Angle (Average AOD), a power Angle spread spectrum of the Angle of departure, a transmit channel correlation, a receive channel correlation, a transmit beamforming, a receive beamforming, a spatial channel correlation, a spatial filter, or a spatial filtering parameter, or a spatial receiving parameter.

4. Time domain/time unit: at least comprises a plurality of time sampling points, which can be frames, wireless frames, system frames, subframes, half frames, time slots, mini-slots, symbols and the like. The time domain/time cell involved in the following expressions are all indicated by slots.

5. Data: may refer to a codeword, a transport block, a code block of code blocks, a code block group of code blocks.

6. Frequency domain resources: the frequency domain resources mentioned in the embodiments of the present application may refer to physical frequency domain resources, or virtual frequency domain resources.

In addition, in order to facilitate understanding of the embodiments of the present application, the following description is made.

First, in the present application, when numbering is referred to, the numbering may be continued from 0 for convenience of description. For example, the 0 th symbol in a certain slot may refer to the first symbol of the slot. Of course, the specific implementation is not limited thereto. For example, the numbers may be consecutively numbered from 1. For example, the 1 st symbol in a certain slot may also refer to the first symbol of the slot. Because the starting values of the numbers are different, the numbers corresponding to the same symbol in the time slot are also different.

It should be understood that the above descriptions are provided for convenience of describing the technical solutions provided by the embodiments of the present application, and are not intended to limit the scope of the present application.

Second, the first, second and various numerical numbers in the embodiments shown below are merely for convenience of description and are not intended to limit the scope of the embodiments of the present application. For example, different frequency domain resources, different TCI states, etc. are distinguished.

Third, in the embodiments illustrated below, "pre-acquisition" may include signaling by the network device or pre-defined, e.g., protocol definition. The "predefined" may be implemented by saving a corresponding code, table, or other means that can be used to indicate the relevant information in advance in the device (for example, including the terminal device and the network device), and the present application is not limited to a specific implementation manner thereof.

Fourth, the term "store" referred to in the embodiments of the present application may refer to a store in one or more memories. The one or more memories may be provided separately or integrated in the encoder or decoder, the processor, or the communication device. The one or more memories may also be provided separately, with a portion of the one or more memories being integrated into the decoder, the processor, or the communication device. The type of memory may be any form of storage medium and is not intended to be limiting of the present application.

Fifth, the "protocol" referred to in the embodiments of the present application may refer to a standard protocol in the communication field, and may include, for example, an LTE protocol, an NR protocol, and a related protocol applied in a future communication system, which is not limited in the present application.

Sixth, "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, at least one (one) of a, b, and c, may represent: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b and c. Wherein a, b and c may be single or plural respectively.

For the convenience of understanding the embodiments of the present application, a communication system suitable for the data transmission method provided in the embodiments of the present application will be described in detail below by taking the communication system shown in fig. 1 as an example. Fig. 1 shows a schematic diagram of a communication system 100 suitable for use in the method of transmitting and receiving data of an embodiment of the present application. As shown, the communication system 100 may include at least one terminal device, such as the terminal device 101 shown in the figure; the communication system 100 may also include at least one network device, such as network device #1102 or network device # 2103 as shown.

Alternatively, the communication system 100 may include a plurality of network devices, such as network device #1102 and network device # 2103 as shown. The network device #1102 and the network device # 2103 may be network devices in the same cell or network devices in different cells, which is not limited in this application. The figure shows an example in which network device #1102 and network device # 2103 are located in the same cell, for example only.

At present, the frequency domain resources used by network devices to transmit data in different time units are the same, while the frequency domain resources corresponding to different time units have different qualities, which is more obvious.

Therefore, a frequency domain resource allocation scheme for frequency domain resource indication associated TCI state is proposed.

Fig. 2 is a schematic flow chart diagram of a method 200 of data transmission provided by an embodiment of the present application, shown from the perspective of device interaction. As shown, the method 200 may include steps 210 and 220. The steps in method 200 are described in detail below.

It should be noted that the method for data transmission provided in the present application may be applied to a wireless communication system, for example, the communication system 100 shown in fig. 1. Communication devices in a communication system may have wireless communication connections between them. For example, the terminal apparatus 101 shown in fig. 1 may have a wireless communication connection relationship with the network apparatus #1102 and the network apparatus # 2103, respectively. The network device #1102 and the network device # 2103 may be an ideal backhaul link or a non-ideal backhaul link, which is not limited in this application.

The network devices shown hereinafter may correspond to, for example, network device #1102 and/or network device # 2103 in fig. 1. It should be understood that in the embodiment shown below, network device #1102 and/or network device # 2103 configure frequency domain transmission resources for terminal device 101.

In step 210, the terminal device receives indication information from the network device. Accordingly, the network device transmits the indication information to the terminal device.

Specifically, the indication information includes N frequency domain resource indications, each frequency domain resource indication is associated with one or more transmission configuration indication states TCI State, each TCI State corresponds to multiple transmission time units, and each frequency domain resource indication is used for indicating a frequency domain transmission resource in each transmission time unit in the multiple transmission time units corresponding to its associated TCI State; wherein at least two of the frequency domain transmission resources indicated by the N frequency domain resource indications are different, and N is an integer equal to or greater than 1.

The following description is given by taking an example of a slot (slot) as a transmission time unit, and those skilled in the art can understand that the transmission time unit may further include a symbol (symbol), a mini-slot (mini-slot), a frame (frame), or the like.

Optionally, the indication information includes N frequency domain indication domains, and is used to carry N frequency domain resource indications. An example is that, as shown in fig. 3, two frequency domain indication domains are taken as an example and are respectively denoted as a frequency domain indication domain 1 and a frequency domain indication domain 2, where the frequency domain indication domain 1 is used to indicate a frequency domain transmission resource 1, and the frequency domain indication domain 2 is used to indicate a frequency domain transmission resource 2. Or, the frequency domain indication field 1 is used to indicate the frequency domain transmission resource 1, the frequency domain indication field 2 indicates a value, and the frequency domain transmission resource 2 is determined based on the frequency domain transmission resource 1 and the value. The indication of the frequency domain indication domain 1 is associated with TCI state1, and the transmission time units corresponding to TCI state1 are slots 1 and slots 3; the indication of the frequency domain indication domain 2 is associated with TCI state2, and the transmission time units corresponding to TCI state2 are slot2 and slot 4. Another example is that, as shown in fig. 5, two frequency domain indication domains are taken as an example and are respectively denoted as a frequency domain indication domain 1 and a frequency domain indication domain 2, where the frequency domain indication domain 1 is used to indicate a frequency domain transmission resource 1, and the frequency domain indication domain 2 is used to indicate a frequency domain transmission resource 2. The indication of the frequency domain indication domain 1 is associated with TCI state1 and TCI state2, and the corresponding transmission time units of TCI state1 and TCI state2 are slot1 and slot 3; the indication of the frequency domain indication domain 2 is associated with TCI state3, and the transmission time units corresponding to TCI state3 are slot2 and slot 4.

Optionally, the indication information includes 1 frequency domain indication domain, and is used to carry N frequency domain resource indications. An example is that, as shown in fig. 4, 1 frequency domain indication domain indicates both frequency domain transmission resource 1 and frequency domain transmission resource 2. The indication of the frequency domain indication domain 1 is associated with the TCI state1, and the transmission time units corresponding to the TCI state1 are slots 1 and slots 3; the indication of the frequency domain indication domain 2 is associated with TCI state2, and the transmission time units corresponding to TCI state2 are slot2 and slot 4. Another example is that, as shown in fig. 6, 1 frequency domain indication domain indicates both frequency domain transmission resource 1 and frequency domain transmission resource 2. The indication of the frequency domain indication domain 1 is associated with TCI state1 and TCI state2, and the corresponding transmission time units of TCI state1 and TCI state2 are slot1 and slot 3; the indication of the frequency domain indication domain 2 is associated with TCI state3, and the transmission time units corresponding to TCI state3 are slot2 and slot 4.

In a possible embodiment, the frequency domain transmission resource 1 and the frequency domain transmission resource 2 indicated by the frequency domain resource are different frequency domain transmission resources in order to realize frequency hopping between different network devices without considering frequency domain offset (offset) or being uniformly configured from another perspective or with default frequency domain offset being 0. As shown in fig. 7, the frequency domain transmission resource used by the transmission time units slot1 and slot3 corresponding to the TCI state1 for data transmission is frequency domain transmission resource 1, and the frequency domain transmission resource used by the transmission time units slot2 and slot4 corresponding to the TCI state2 for data transmission is frequency domain transmission resource 2. It can be seen that, in this embodiment, when data is transmitted, frequency domain transmission resources used for transmitting data in transmission time units corresponding to different TCI states are different.

In another possible implementation, the frequency domain transmission resource 1 and the frequency domain transmission resource 2 indicated by the frequency domain resource are the same frequency domain transmission resource, the first slot where each network device starts to transmit (for example, the first slot of the network device 1 corresponding to the TCI state1 is slot1, and the first slot of the network device 2 corresponding to the TCI state2 is slot2) does not relate to a frequency domain offset or may consider that the frequency domain offset is 0, and except for the first slot corresponding to each network device, the frequency domain offsets corresponding to other slots are the same and are not 0. Then, as shown in fig. 8, the frequency domain transmission resource used by the transmission time unit slot1 corresponding to the TCI state1 for transmitting data is frequency domain transmission resource 1, and the frequency domain transmission resource used by the transmission time unit slot3 corresponding to the TCI state1 for transmitting data is determined by both the frequency domain transmission resource 1 and the frequency domain offset. The frequency domain transmission resource used by the transmission time unit slot2 corresponding to the TCI state2 for transmitting data is frequency domain transmission resource 2, and the frequency domain transmission resource used by the transmission time unit slot4 corresponding to the TCI state2 for transmitting data is determined by both the frequency domain transmission resource 2 and the frequency domain offset. Optionally, the frequency domain offsets corresponding to other slots are different. Optionally, the frequency domain offset corresponding to each time domain unit may be configured by the network device in a unified manner, or configured by the network device for different time domain units, or may be specified by a protocol, for example, according to the parity of a slot number, to correspond to different offset adjustment coefficients (e.g., 0,1, etc.), and after the network device configures the frequency domain offset, the terminal device performs an operation according to the frequency domain offset and the offset adjustment coefficients to obtain the corresponding offset. It can be seen that, in this embodiment, when data is transmitted, frequency domain transmission resources used by transmission time units corresponding to the same TCI state are different.

In another possible embodiment, the frequency domain resource indication indicates only one frequency domain transmission resource 1, as shown in fig. 9, the transmission time unit corresponding to the TCI state1 is slot1, slot2, slot3, slot4, the frequency domain transmission resource used for transmitting data in slot1 is frequency domain transmission resource 1, and the frequency domain transmission resource used for transmitting data in the transmission time unit slot2 corresponding to the TCI state1 is determined by both the frequency domain transmission resource 1 and the frequency domain offset. Frequency domain transmission resources used by the transmission time units slot3 and slot4 corresponding to the TCI state1 for transmitting data are the same as the frequency domain transmission resources determined by slot1 and slot2, and an offset can be determined according to a parity rule of slot numbers, for example, an offset adjustment coefficient of the slot number is 0 for odd number and an offset adjustment coefficient of the slot number is 1 for even number, if a uniform offset value, for example, X, is configured for the network device, the offset in the slot number of the odd number is 0, the offset in the slot number of the even number is X, and of course, there may be other rules as long as there are frequency hopping (that is, not exactly the same) frequency domain transmission resources on different slots corresponding to the TCI state 1. Optionally, the frequency domain offsets corresponding to other slots may be configured by the network device uniformly with the shared frequency domain offset, or configured by the network device respectively for different time domain units, and the like. It can be seen that, in this embodiment, when data is transmitted, frequency domain transmission resources used by adjacent transmission time units corresponding to the same TCI state are different.

In another possible embodiment, the frequency domain transmission resource 1 and the frequency domain transmission resource 2 indicated by the frequency domain resource are different frequency domain transmission resources, the first slot where each network device starts to transmit (for example, the first slot of the network device 1 corresponding to the TCI state1 is slot1, and the first slot of the network device 2 corresponding to the TCI state2 is slot2) does not relate to a frequency domain offset or may consider that its frequency domain offset is 0, and except for the first slot corresponding to each network device, the frequency domain offsets corresponding to other slots are different and are not 0. Then, as shown in fig. 10, the frequency domain transmission resource used by the transmission time unit slot1 corresponding to the TCI state1 for transmitting data is frequency domain transmission resource 1, and the frequency domain transmission resource used by the transmission time unit slot3 corresponding to the TCI state1 for transmitting data is determined by both the frequency domain transmission resource 1 and the frequency domain offset 1. The frequency domain transmission resource used by the transmission time unit slot2 corresponding to the TCI state2 for transmitting data is frequency domain transmission resource 2, and the frequency domain transmission resource used by the transmission time unit slot4 corresponding to the TCI state2 for transmitting data is determined by both the frequency domain transmission resource 2 and the frequency domain offset 2. Optionally, the frequency domain offsets corresponding to other slots are the same and are not 0. Optionally, the frequency domain offset corresponding to each time domain unit may be configured by the network device in a unified manner, or configured by the network device for different time domain units, or may be specified by a protocol, for example, according to the parity of a slot number, to correspond to different offset adjustment coefficients (e.g., 0,1, etc.), and after the network device configures the frequency domain offset, the terminal device performs an operation according to the frequency domain offset and the offset adjustment coefficients to obtain the corresponding offset. It can be seen that, in the embodiment, when data is transmitted, frequency domain transmission resources used by transmission time units corresponding to the same TCI state are different; the frequency domain transmission resources used by the transmission time units corresponding to different TCI states are different.

For the sake of distinction and illustration, in step 210, at least two frequency domain transmission resources are different, including: at least two frequency domain transmission resources in a plurality of transmission time units corresponding to the same TCI state are different.

As shown in fig. 8, taking transmission time units slot1 and slot3 corresponding to TCI state1 as an example, frequency domain transmission resources in slot1 and slot3 are different, that is, frequency domain transmission resources of transmission time unit slot1 corresponding to TCI state1 are f2-f4, and frequency domain transmission resources of transmission time unit slot3 corresponding to TCI state1 are f1-f 3.

The at least two frequency domain transmission resources are different, including: at least two frequency domain transmission resources in one transmission time unit respectively corresponding to different TCI states are different.

As shown in fig. 6, taking transmission time unit slot1 corresponding to TCI state1 and transmission time unit slot2 corresponding to TCI state2 as an example, frequency domain transmission resources in slot1 and slot2 are different, that is, frequency domain transmission resources of transmission time unit slot1 corresponding to TCI state1 are f2-f4, and frequency domain transmission resources of transmission time unit slot2 corresponding to TCI state2 are f1-f 3.

The at least two frequency domain transmission resources are different, including: at least two frequency domain transmission resources in a plurality of transmission time units corresponding to the same TCI State are different, and at least two frequency domain transmission resources in one frequency domain transmission resource in one transmission time unit corresponding to different TCI states are different.

As shown in fig. 9, taking transmission time units slot1, slot3 and transmission time units slot2 and slot4 corresponding to TCI state2 corresponding to TCI state1 as examples, frequency domain transmission resources in transmission time unit slot1 and slot3 corresponding to TCI state1 are different, that is, frequency domain transmission resources of transmission time unit slot1 corresponding to TCI state1 are f4-f8, and frequency domain transmission resources of transmission time unit slot3 corresponding to TCI state1 are f3-f 7. The frequency domain transmission resources in the transmission time unit slot2 and the slot4 corresponding to the TCI state2 are different, that is, the frequency domain transmission resources of the transmission time unit slot2 corresponding to the TCI state2 are f2-f6, and the frequency domain transmission resources of the transmission time unit slot4 corresponding to the TCI state2 are f1-f 5. The frequency domain transmission resources of the transmission time unit slot1 corresponding to the TCI state1 are f4-f8, and the frequency domain transmission resources of the transmission time unit slot2 corresponding to the TCI state2 are f2-f 6.

Optionally, the TCI states associated with the same frequency domain resource indication belong to a TCI state group; the TCI state groups are divided according to a predetermined grouping rule, or are configured by the network device. Optionally, the indication information is downlink control information DCI.

In step 220, the terminal device determines the frequency domain transmission resources indicated by the N frequency domain resource indications.

Optionally, the frequency domain resource indication is used to directly indicate the frequency domain transmission resource or indirectly indicate the frequency domain transmission resource.

In one possible embodiment, the frequency domain resource indication is used to directly indicate the frequency domain transmission resources. And the terminal equipment directly transmits data according to the frequency domain transmission resource indicated by the frequency domain resource.

In another possible embodiment, the frequency domain resource indication is used to indirectly indicate frequency domain transmission resources. And the frequency domain resource indication indicates frequency domain transmission resources, and the frequency domain transmission resources indicated by the N frequency domain resource indications are determined according to the frequency domain offset corresponding to each time domain unit in the frequency domain transmission resources indicated by the frequency domain resource indication domain and a plurality of time domain units corresponding to the TCI state associated with the frequency domain transmission resources.

The frequency domain transmission resources configured for the terminal device may be the same or different for different network devices. The frequency domain offset corresponding to each time domain unit may be configured by the higher layer signaling in a unified manner or configured separately, and the configured frequency domain offsets may be the same or different.
