Description

A channel transmission method, apparatus, device, chip, and storage medium Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to a channel transmission method, apparatus, device, chip, and storage medium. Background Technology

[0002] Existing systems and protocols employ or discuss two main duplex technologies: dynamic time division duplex (TDD), which flexibly changes the transmission direction of each time slot, and subband non-overlapping full duplex (SBFD), which embeds uplink subbands into downlink time slots. Both technologies face the problem of cross-link interference (CLI) between base stations caused by the flexibility of uplink and downlink configurations. Specifically, when adjacent base stations are configured with different transmission directions, or when adjacent base stations simultaneously receive uplink data and transmit downlink data in SBFD time slots, the base station receiving uplink data will be interfered with by the downlink transmission of adjacent base stations due to the extremely high downlink transmission power of the base station. To address the cross-link interference problem with better scheduling strategies, accurate assessment of interference signals is needed, which is beneficial for receiver enhancement design.

[0003] Therefore, in order to satisfy both the measurement of interference covariance of only empty resource elements (REs) and the measurement of pilot signals of adjacent base stations that conform to a certain time-frequency domain arrangement, designing a reasonable uplink silent resource configuration method and channel transmission rules is an urgent problem to be solved.

[0004] Summary of the Invention

[0005] This application provides a channel transmission method, apparatus, device, chip, and storage medium.

[0006] In a first aspect, the channel transmission method provided in the embodiments of this application includes:

[0007] When the uplink channel resources overlap with the first resource, the terminal device transmits uplink channel data according to the first rule; wherein, the uplink channel resources are resources used for transmitting the uplink channel, and the first resource is a resource used for interference measurement.

[0008] Secondly, the channel transmission method provided in the embodiments of this application includes:

[0009] The network device sends first information, which indicates a first resource, which is a resource used for interference measurement.

[0010] Thirdly, the channel transmission device provided in the embodiments of this application is applied to a terminal device, and the channel transmission device includes:

[0011] The transmitting unit is configured to transmit uplink channel data according to a first rule when uplink channel resources overlap with the first resource.

[0012] Wherein, the uplink channel resource is the resource used for transmitting the uplink channel, and the first resource is the resource used for interference measurement.

[0013] Fourthly, the channel transmission apparatus provided in this application embodiment is applied to a network device, and the channel transmission apparatus includes:

[0014] The receiving unit is configured to receive the uplink channel according to the first rule.

[0015] Fifthly, the terminal device provided in the embodiments of this application includes a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the channel transmission method described above.

[0016] Sixthly, the network device provided in the embodiments of this application includes a processor and a memory. The memory is used to store a computer program, and the processor is used to call and run the computer program stored in the memory to execute the channel transmission method described above.

[0017] The chip provided in this application embodiment is used to implement the channel transmission method described above.

[0018] Specifically, the chip includes a processor for calling and running a computer program from memory, causing a device equipped with the chip to perform the aforementioned channel transmission method.

[0019] The computer-readable storage medium provided in this application embodiment is used to store a computer program that causes a computer to execute the channel transmission method described above.

[0020] The computer program product provided in this application includes computer program instructions that cause a computer to execute the channel transmission method described above.

[0021] The computer program provided in this application embodiment, when run on a computer, causes the computer to execute the channel transmission method described above.

[0022] According to the channel transmission method of this application embodiment, the terminal device can determine the first resource pre-configured by the network device for interference measurement based on the first information sent by the network device. When the first resource for interference measurement overlaps with the resource for uplink channel transmission, the transmission rules of the uplink channel are changed. That is, if there is no uplink channel transmission on the first resource, interference measurement can be performed directly. If there is uplink channel transmission, the overlapping resource is silenced. Based on this, the terminal device can measure the interference situation at any time, thereby obtaining more accurate interference measurement results. The first resource can also correspond to various time-frequency resource mappings of pilot signals of adjacent base stations, which can support the measurement of interference covariance in the presence of empty REs and the measurement of pilot signals, thereby improving the overall resource utilization.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Figure 1 is a schematic diagram of an application scenario of an embodiment of this application.

[0054] As shown in Figure 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0055] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), 6th generation mobile networks (6G) system, or future communication systems, etc.

[0056] In the communication system 100 shown in Figure 1, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., user equipment (UE)) located within that coverage area.

[0058] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0062] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

Optionally, the wireless communication system 100 may include multiple network devices 120, and the coverage area of ​​each network device 120 may include other numbers of terminal devices 110.

[0066] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0067] (1) Subband non-overlapping full duplex (SBFD)

[0068] To overcome the problems of weak uplink coverage, high uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation in NR TDD, the 3rd Generation Partnership Project (3GPP) introduced SBFD technology in Release 18. This technology allows simultaneous transmission and reception of data on different subbands within the same subframe / slot / symbol. This technology is primarily used on the base station side, while the terminal side maintains its current state, meaning that only transmission or reception of data is supported within a single subframe / slot / symbol. As shown in Figures 2 and 3, an uplink (UL) subband is configured in the middle subband of a downlink (DL) link or flexible subframe / slot / symbol.

[0069] When the UL link occupies the full bandwidth, it is considered dynamic TDD technology. This can be seen as an extreme case of SBFD, which allows for dynamic adaptation of the transmission direction of time resources based on time slots.

[0070] In addition, the standard specifies that SBFD subbands (including UL subbands and / or DL ​​subbands) can only be configured on DL symbols and / or flexible symbols configured in TDD-UL-DL-ConfigCommon, i.e., a possible frame structure is shown in Figure 4.

[0071] (2) Uplink resource muting

[0072] Uplink resource silencing is a proposed solution to address cross-link interference (CLI) in SBFD (Site-Based Free-Flight). Specifically, by measuring cross-link interference (CLI) between base stations in resource elements that lack uplink transmission, the interference covariance matrix can be accurately obtained. Applying this to the receiver of enhanced base stations can effectively improve the uplink coverage reduction caused by CLI between base stations. Figure 5 illustrates an example of uplink resource silencing. The basic configuration of uplink resource silencing was agreed upon at the R19 RAN#117 meeting as follows:

[0073] If non-transparent UL resource muting is supported for gNB-to-gNB CLI handling, Option 1 is recommended to be specified.

[0074] In some embodiments, this is used for Mode 2 (Comb-2) of both single-carrier orthogonal frequency division multiplexing (OFDM) and cyclic prefix OFDM (CP-OFDM).

[0075] It should be noted that additional details can be discussed in RAN1#117.

[0076] It should be noted that power boosting is assumed for REs in the symbol with UL resource muting (FFS:Details).

[0077] It should also be noted that the above content is subject to separate UE capabilities (including separate capabilities for DFT-S-OFDM and CP-OFDM).

[0078] As shown in Figure 6, an feasible time-frequency domain resource configuration method for uplink muting resources is given. It can be seen that uplink muting resources can be configured in the time-frequency domain resources of the demodulation reference signal (DMRS) and the physical uplink shared channel (PUSCH).

[0079] Existing systems and protocols employ or discuss two duplexing technologies: dynamic TDD, which flexibly changes the transmission direction of each time slot, and SBFD, which embeds uplink subbands into downlink time slots. Both technologies face the CLI problem between base stations caused by the flexibility of uplink and downlink configurations. Specifically, when adjacent base stations are configured with different transmission directions, or when adjacent base stations simultaneously receive uplink data and transmit downlink data in SBFD time slots, the base station receiving uplink data will experience interference from the downlink transmission of adjacent base stations due to the extremely high downlink transmission power of the base station. To address cross-link interference with better scheduling strategies, accurate assessment of interference signals is needed to facilitate receiver enhancement design.

[0080] Currently, Release 19 does not discuss uplink silencing resource configuration methods and enabling rules. In order to satisfy both the measurement of interference covariance requiring only empty resource elements (REs) and the measurement of pilot signals from adjacent base stations with a certain time-frequency domain arrangement, designing a reasonable uplink silencing resource configuration method and silencing rules is an urgent problem to be solved. Secondly, considering that the strength of interference signals is almost the same in one or several slots, and uplink resource silencing will cause some uplink resources to be unable to transmit, if only the uplink signals used for measurement are effectively silenced, it will lead to a decrease in overall resource utilization and uplink throughput. Therefore, it is also necessary to further optimize the uplink silencing resource configuration method to ensure its efficiency.

[0081] In view of this, embodiments of this application provide a channel transmission method in which the terminal device can change the transmission rules of the uplink channel when there is overlap between the first resource used for interference measurement and the resource used for uplink channel transmission. Based on this, the terminal device can measure the interference situation at any time, thereby obtaining more accurate interference measurement results, which is beneficial to the subsequent enhancement design of the receiver.

[0082] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0083] Figure 7 illustrates a channel transmission method provided in an embodiment of this application, which may include:

[0084] S700: When the uplink channel resources and the first resource overlap, the terminal equipment transmits uplink channel resources according to the first rule; wherein, the uplink channel resources are resources used for transmitting uplink channels, and the first resource is a resource used for interference measurement.

[0085] It should be noted that uplink channel resources are resources used for uplink channel transmission. This can be understood as the uplink channel resources being configured for uplink channel transmission, but the resources actually used for uplink channel transmission can be all or part of these uplink channel resources. Similarly, the first resource is configured for interference measurement, and the resources actually used for interference measurement can be all or part of the first resource.

[0086] In this embodiment, when the uplink channel resources used for transmitting the uplink channel overlap with the first resources used for interference measurement, the terminal device transmits the uplink channel according to the first rule.

[0087] In some embodiments, the first rule includes: if the overlapping resources of the uplink channel resources and the first resource include the second resource, the terminal device determines that the second resource is not used for uplink channel transmission; wherein, the second resource is the uplink channel resource used for transmitting signals other than the reference signal in the uplink channel.

[0088] For example, if the uplink channel resources of the terminal device overlap with the first resource, and the overlapping resources include the second resource of the uplink channel resources used for transmitting signals other than the reference signal in the uplink channel, then the terminal device determines that the second resource is not used for uplink channel transmission; that is, if the overlapping resources include non-reference signal resources, uplink channel transmission can be avoided on the non-reference signal resources, and the non-reference signal resources can be used for interference measurement.

[0089] In some embodiments, the first rule includes: if the overlapping resources of the uplink channel resources and the first resources include a third resource, the terminal device determines that the transmission of the reference signal in the uplink channel occupies the third resource; wherein, the third resource is the resource in the uplink channel resources used for transmitting the reference signal in the uplink channel.

[0090] For example, if the uplink channel resources of the terminal device overlap with the first resource, and the overlapping resources include a third resource in the uplink channel resources used for transmitting the reference signal in the uplink channel, then the terminal device determines that the transmission of the reference signal in the uplink channel occupies the third resource; that is, if the overlapping resources include the reference signal resource, the uplink channel transmission can be performed normally on the reference signal resource, and therefore, the reference signal resource cannot be occupied for interference measurement.

[0091] In some embodiments, the reference signal includes, but is not limited to, any one of the following: demodulation reference signal (DMRS); sounding reference signal (SRS); enhanced sounding reference signal (E-SRS); phase tracking reference signal (PTRS).

[0092] For example, if the overlapping resources of the uplink channel resources and the first resource include one or more of the following resources: DMRS resources, SRS resources, E-SRS resources, and PTRS resources, then the terminal device does not use these resources for interference measurement, and these resources can still be used for uplink channel transmission.

[0093] In some embodiments, the terminal device receives first information, which includes configuration information of at least one set of first resources.

[0094] For example, a terminal device receives first information sent by a network device. Since the first information includes configuration information of at least one set of first resources, the terminal device can determine one or more first resources based on the configuration information of at least one set of first resources. Each set of configuration information of first resources can determine one first resource, and each set of configuration information of first resources can also determine multiple first resources. At least one set of configuration information of first resources can also determine one first resource.

[0095] In another example, after determining the first resource based on the first information, the terminal device determines whether there is resource overlap with the first resource in the uplink channel resources. If there is, it determines whether the overlapping resources include the second resource or whether the overlapping resources include the third resource. If the overlapping resources include the second resource, the terminal device determines that the second resource is not used for uplink channel transmission. If the overlapping resources include the third resource, the terminal device determines that the transmission of the reference signal in the uplink channel occupies the third resource.

[0096] In some embodiments, the configuration information of the first resource includes: bandwidth indication information for indicating the bandwidth of the first resource; period indication information for indicating the period of the first resource; frequency domain indication information for indicating the subcarrier or RE occupied by the first resource; and time domain indication information for indicating the symbol occupied by the first resource.

[0097] It should be noted that the network device indicates the first resource to the terminal device through the configuration information of the first resource. Among them, the bandwidth indication information is used to indicate the system bandwidth occupied by the first resource, the period indication information is used to indicate the time domain period of the first resource, the frequency domain indication information is used to indicate the symbol position of the first resource in a time slot, and the time domain indication information is used to indicate the subcarrier position occupied by the first resource in a RB.

[0098] In some embodiments, the bandwidth indication information includes:

[0099] First bandwidth information, which is used to indicate the total system bandwidth and / or sub-bandwidth occupied by the first resource;

[0100] Second bandwidth information, which is used to indicate one or more first resource blocks (RBs) that are continuous or discrete within the full bandwidth and / or sub-bandwidth of the first resource.

[0101] It should be noted that the first bandwidth information in the bandwidth indication information can be used to indicate the system bandwidth occupied by the first resource, and the second bandwidth information in the bandwidth indication information can be used to indicate the system bandwidth occupied by the first resource. It is also possible to indicate the system bandwidth occupied by the first resource simultaneously through the first bandwidth information and the second bandwidth information. This application embodiment does not limit this.

[0102] In some embodiments, the second bandwidth information includes any one of the following: one or more first resource block (RB) indices; the starting first resource block (RB) index and the number of first resource blocks (RBs); first resource block (RB) mapping information; and first resource block (RB) comb mapping interval values.

[0103] It should be noted that since there are multiple resource blocks (RBs) on the system's full bandwidth and / or sub-bandwidth, the second bandwidth information can indicate one or more first resource blocks (RBs) that are consecutive or discrete among the multiple resource blocks (RBs) occupying the system's full bandwidth and / or sub-bandwidth.

[0104] As an example, one or more first resource block (RB) indices included in the second bandwidth information are used to indicate the location of the first resource block (RB). Since corresponding indices are pre-edited for each resource block (RB) of the system's full bandwidth and / or sub-bandwidth, the first resource block (RB) can be indicated by one or more first resource block (RB) indices. For example, if one or more first resource block (RB) indices included in the second bandwidth information are indices 2, 5, and 10, then the resource block (RB) with indices 2, 5, and 10 among the multiple resource block (RB) in the system's full bandwidth and / or sub-bandwidth is the first resource block (RB).

[0105] In another example, the starting first resource block RB index and the number of first resource block RBs included in the second bandwidth information are used to indicate the position of the first resource block RB. Since the corresponding index is pre-edited for each resource block RB of the system's full bandwidth and / or sub-bandwidth, the starting resource block RB in the first resource block RB can be indicated by the starting first resource block RB index, and the number of resource block RBs in the first resource block RB can be indicated by the number of first resource block RBs. For example, if the starting first resource block RB index and the number of first resource block RBs included in the second bandwidth information are index 5 and number 5, respectively, then the five consecutive resource block RBs starting with the resource block RB with index 5 in the multiple resource block RBs of the system's full bandwidth and / or sub-bandwidth are the first resource block RBs.

[0106] In another example, the first resource block (RB) mapping information included in the second bandwidth information is used to indicate the location of the first resource block (RB). Since the number of bits in the first resource block (RB) mapping information bitmap is the same as the number of multiple resource blocks (RBs) on the system's full bandwidth and / or sub-bandwidth, each bit in the first resource block (RB) mapping information bitmap corresponds to one resource block (RB). A bit value of 1 indicates that the corresponding resource block (RB) is occupied by the first resource and is the first resource block (RB), while a bit value of 0 indicates that the corresponding resource block (RB) is not occupied by the first resource and is not the first resource block (RB). For example, if the first, fifth, seventh, and fourteenth bits in the first resource block (RB) mapping information bitmap included in the second bandwidth information have a bit value of 1, and the remaining bits have a bit value of 0, then the four resource blocks (RBs) corresponding to the first, fifth, seventh, and fourteenth bits constitute the first resource block (RB).

[0107] In another example, the first resource block RB comb mapping interval value included in the second bandwidth information is used to indicate the location of the first resource block RB. In this case, the first resource block RB comb mapping interval value is used to indicate the first resource block RB from multiple resource block RBs on the full bandwidth and / or sub-bandwidth of the system. For example, if the first resource block RB comb mapping interval value included in the second bandwidth information is 4, then starting from the first resource block RB among multiple resource block RBs on the full bandwidth and / or sub-bandwidth of the system, every 4 resource block RBs occupy 1 resource block RB to form the first resource block RB.

[0108] In some embodiments, bandwidth indication information is used to indicate bandwidth associated with the time slot type of the first time slot; the first time slot is a time slot occupied by a first resource.

[0109] In some embodiments, the time slot type is at least any one of the following: uplink time slot; subband non-overlapping full-duplex (SBFD) time slot.

[0110] It should be noted that at least one set of configuration information for the first resource can be configuration information corresponding to at least one time slot type, that is, each time slot type can correspond to a set of configuration information for the first resource.

[0111] For example, if the time slot type includes uplink time slots and SBFD time slots, then the first information may include configuration information of a set of first resources corresponding to the uplink time slot and configuration information of a set of first resources corresponding to the SBFD time slot.

[0112] Correspondingly, the bandwidth indication information can instruct the network device to configure the first resource on the bandwidth within the uplink time slot, or it can instruct the network device to configure the first resource on the bandwidth within the SBFD time slot.

[0113] For example, if the interfered base station is located in the uplink time slot, in order to measure the interference caused by the downlink transmission of the adjacent base station, the bandwidth occupied by the pilot signal of the adjacent base station, such as the frequency domain pattern of the channel state information reference signal (CSI-RS), can be used to indicate the bandwidth occupied by the first resource in the uplink time slot. As shown in Figure 8, the first bandwidth information indicates that the first resource occupies the full bandwidth of the system (the black box in UL in Figure 8). The subcarrier positions within the full bandwidth of the first resource occupying the system are consistent with the frequency domain pattern of CSI-RS (DL in Figure 8). As shown in Figure 9, the first bandwidth information indicates the sub-bandwidth of the first resource occupying the system (the black dashed box in UL in Figure 9). The subcarrier positions within the sub-bandwidth of the first resource occupying the system are consistent with the frequency domain pattern of CSI-RS (DL subband1 and DL subband3 in Figure 9). Correspondingly, the second bandwidth information can also indicate one or more first resource blocks RBs that are continuous or discrete in the full bandwidth and / or sub-bandwidth of the first resource occupying the system.

[0114] In another example, if the interfered base station is located in the SBFD time slot, in order to measure the interference caused by the downlink transmission of the adjacent base station, the bandwidth occupied by the pilot signal of the adjacent base station, such as the frequency domain pattern of CSI-RS, can be used to indicate the bandwidth occupied by the first resource in the SBFD time slot. As shown in Figure 10, the first resource occupies the full bandwidth of the system (the black dashed box in UL in Figure 10) through the first bandwidth information. The subcarrier positions inside the full bandwidth UL of the first resource occupy the system are consistent with the frequency domain pattern of CSI-RS (DL in Figure 10). As shown in Figure 11, the first resource occupies the sub-bandwidth of the system (the black dashed box in UL in Figure 11) through the first bandwidth information. The subcarrier positions inside the sub-bandwidth of the first resource occupy the system are consistent with the frequency domain pattern of CSI-RS (DL subband1 and DL subband3 in Figure 11). Correspondingly, the first resource occupies the full bandwidth of the system and / or the sub-bandwidths, and one or more first resource blocks RB, which are continuous or discrete, can also be indicated by the second bandwidth information.

[0115] It should be noted that network devices can configure different first resource configurations for uplink time slots and SBFD time slots, meaning that all or part of the first information corresponding to the uplink time slot and SBFD time slot is different. Alternatively, they can configure the same first resource configuration for uplink time slots and SBFD time slots, meaning that the first information corresponding to the uplink time slot and SBFD time slot is the same, that is, only the first information is configured, without distinguishing them by time slot type.

[0116] It is understandable that keeping the configuration methods of SBFD slots and uplink slots consistent can reduce the signaling overhead required for configuring resources.

[0117] In summary, to meet the requirements of interference measurement, when there is signaling interaction between the interfered base station and the neighboring interfering base station, such as time slot type configuration or pilot signal time-frequency pattern arrangement, the interfered base station (network device) can compare its own serving user time slot type configuration with that of the neighboring base station to provide the most matching first resource configuration method. For example, only empty REs are used to measure interference covariance. A simple configuration method that saves signaling overhead is to use full bandwidth configuration for both uplink time slots and SBFD time slots. Furthermore, according to different time slot types, the first resource for interference measurement can be configured on all or part of the RBs in the full bandwidth or uplink subband, all or part of the subcarriers on the RBs, or on the REs.

[0118] In some embodiments, the period indication information includes one or more of the following: period attribute information, which indicates whether the first resource is configured periodically or aperiodically; period configuration information, which indicates the number of time-domain units included in the period; and offset configuration information, which indicates the time-domain location of the first time slot within the period.

[0119] It should be noted that the network device first indicates whether the first resource is periodically configured or aperiodically configured through the periodic attribute information in the periodic indication information. If the first resource is periodically configured, then the number of time domain units included in each period is indicated through the periodic configuration information, and finally the first time slot in each period is indicated through the offset configuration information. It can be seen that if the first resource is aperiodically configured, the periodic indication information may not include the periodic configuration information and the offset configuration information.

[0120] In some embodiments, the time-domain location of the first time slot is related to the time slot type within the period.

[0121] For example, if the time slot type includes uplink time slots and SBFD time slots, the network device can configure the first time slot in the uplink time slot and the first time slot in the SBFD time slot. The configurations of the first time slot in the uplink time slot and the first time slot in the SBFD time slot can be the same, different, or partially different.

[0122] In some embodiments, the number of time slot types is multiple, and the time domain position of the first time slot includes: the time domain position corresponding to each time slot of the first time slot type within the period; the time domain position corresponding to a portion of the time slots of multiple consecutive time slots of the first time slot type within the period; wherein, the first time slot type is one or more of multiple time slot types.

[0123] For example, if the time slot type includes uplink time slots and SBFD time slots, the network device can configure the first resource on each of the uplink time slots and / or SBFD time slots within the period.

[0124] In another example, if the time slot type includes uplink time slots and SBFD time slots, the network device can configure the first resource on some of the uplink time slots and / or some of the SBFD time slots when there are multiple consecutive uplink time slots and / or multiple consecutive SBFD time slots.

[0125] It is understandable that configuring the first resource on each time slot can ensure accurate measurement of interference. However, configuring the first resource on only one or a few of the M consecutive time slots is because the interference between symbols in the same type of time slot is roughly the same, and excessive configuration of the first resource will reduce the uplink throughput.

[0126] In some embodiments, the time slot type includes uplink time slots and SBFD time slots, and the time domain position of the first time slot includes at least one of the following: the time domain position corresponding to each uplink time slot within the period; the time domain position corresponding to each SBFD time slot within the period; the time domain position corresponding to each uplink time slot and the time domain position corresponding to each SBFD time slot within the period; the time domain position corresponding to one or more uplink time slots among a plurality of consecutive uplink time slots within the period; the time domain position corresponding to one or more SBFD time slots among a plurality of consecutive SBFD time slots within the period; the time domain position corresponding to one or more time slots among a plurality of first time slot groups within the period; the first time slot group includes at least one uplink time slot and at least one SBFD time slot, wherein the at least one uplink time slot and the at least one SBFD time slot are consecutive in the time domain.

[0127] As an example, a network device can configure the first resource on each uplink slot / each SBFD slot within a period, as shown in Figure 12. The black dashed box in Figure 12 indicates that the first resource is configured only on each uplink slot, as shown in Figure 13. The black dashed box in Figure 13 indicates that the first resource is configured only on each SBFD slot.

[0128] In another example, the network device can configure a first resource on each uplink time slot and each SBFD time slot within a cycle, as shown in Figure 14. The black dashed box in Figure 14 indicates that the first resource can be configured on both the uplink time slot and each SBFD time slot. Considering that the bandwidth configured for the uplink time slot and the SBFD time slot may be different, the first resource can occupy all or part of the bandwidth used for uplink transmission in the uplink time slot and / or the SBFD time slot, as shown in Figure 15. The black dashed box in Figure 15 indicates that the first resource can be configured on both the SBFD time slot and a portion of the bandwidth of each uplink time slot. As shown in Figure 16, several examples of bandwidth configuration on the uplink time slot are given. The bandwidth configuration on the uplink time slot can correspond to the pilot signals of adjacent base stations.

[0129] In another example, when a network device encounters M consecutive uplink time slots within a period, it can select one or more uplink time slots to configure the first resource. Similarly, when a network device encounters M consecutive SBFD time slots within a period, it can select one or more SBFD time slots to configure the first resource. Typically, the first resource can be configured at any position at the beginning, middle, or end of the M consecutive uplink time slots or M consecutive SBFD time slots, as shown in Figure 17, where M is 2. Once two consecutive uplink time slots or two consecutive SBFD time slots appear, the first resource is configured at the beginning of the two consecutive uplink time slots and at the end of the two consecutive SBFD time slots.

[0130] In some embodiments, the number of one or more uplink time slots is N1, and the one or more uplink time slots are any N1 time slots within a first time slot range of multiple consecutive uplink time slots. The first time slot range is the first M1 time slots, or the K1th time slot to the K1+M1th time slots, or the last M1 time slots in the multiple consecutive uplink time slots; N1, M1, and K1 are all integers greater than or equal to 1, and N1 is less than or equal to M1.

[0131] The number of one or more SBFD time slots is N2. One or more SBFD time slots are any N2 time slots within the second time slot range of multiple consecutive SBFD time slots. The second time slot range is the first M2 time slots, or the K2th time slot to the K2+M2th time slots, or the last M2 time slots in the multiple consecutive SBFD time slots. N2, M2, and K2 are all integers greater than or equal to 1, and N2 is less than or equal to M2.

[0132] The number of one or more time slots is N3. One or more time slots are any N3 time slots within the third time slot range of the first time slot group. The third time slot range is the first M3 time slots in the first time slot group, or the K3th time slot to the K3+M3th time slot, or the last M3 time slots. N3, M3, and K3 are all integers greater than or equal to 1, and N3 is less than or equal to M3.

[0133] For example, if N1 equals 1, the first resource can be configured at any position in multiple consecutive uplink time slots, such as configuring the first resource at the beginning of multiple consecutive uplink time slots, that is, configuring the first resource at any position in the first M1 time slots of multiple consecutive uplink time slots; similarly, if N2 equals 1, the first resource can be configured at any position in multiple consecutive SBFD time slots, such as configuring the first resource at the beginning of multiple consecutive SBFD time slots, that is, configuring the first resource at any position in the first M2 time slots of multiple consecutive SBFD time slots; similarly, if N3 equals 1, the first resource can be configured at any position in both multiple consecutive uplink time slots and multiple consecutive SBFD time slots, such as configuring the first resource at the beginning of both multiple consecutive uplink time slots and multiple consecutive SBFD time slots, that is, configuring the first resource at any position in the first M3 time slots of both multiple consecutive uplink time slots and multiple consecutive SBFD time slots.

[0134] In another example, if N1 is greater than 1, the first resource can be centrally deployed at the beginning of multiple consecutive uplink time slots, i.e., multiple locations are selected to configure the first resource in the first M1 time slots of multiple consecutive uplink time slots; it can also be centrally deployed at the middle of multiple consecutive uplink time slots, i.e., multiple locations are selected to configure the first resource in the K1 to K1+M1 time slots of multiple consecutive uplink time slots; it can also be centrally deployed at the end of multiple consecutive uplink time slots, i.e., multiple locations are selected to configure the first resource in the last M1 time slots of multiple consecutive uplink time slots; or the first resource can be evenly deployed at multiple locations in multiple consecutive uplink time slots.

[0135] Correspondingly, if N2 is greater than 1, the first resource can be centrally deployed at the beginning of multiple consecutive SBFD time slots, i.e., multiple locations are selected to configure the first resource in the first M2 time slots of multiple consecutive SBFD time slots; it can also be centrally deployed at the middle of multiple consecutive SBFD time slots, i.e., multiple locations are selected to configure the first resource in the K2 to K2+M2 time slots of multiple consecutive SBFD time slots; it can also be centrally deployed at the end of multiple consecutive SBFD time slots, i.e., multiple locations are selected to configure the first resource in the last M2 time slots of multiple consecutive SBFD time slots; or the first resource can be evenly deployed at multiple locations in multiple consecutive SBFD time slots.

[0136] Correspondingly, if N3 is greater than 1, the first resource can be deployed simultaneously at the beginning of multiple consecutive uplink time slots and multiple consecutive SBFD time slots, i.e., multiple locations can be selected to configure the first resource in the first M3 time slots of multiple consecutive uplink time slots and multiple consecutive SBFD time slots; alternatively, the first resource can be deployed simultaneously at the middle of multiple consecutive uplink time slots and multiple consecutive SBFD time slots, i.e., multiple locations can be selected to configure the first resource in the K3 to K3+M3 time slots of multiple consecutive uplink time slots and multiple consecutive SBFD time slots; alternatively, the first resource can be deployed simultaneously at the end of multiple consecutive uplink time slots and multiple consecutive SBFD time slots, i.e., multiple locations can be selected to configure the first resource in the last M3 time slots of multiple consecutive uplink time slots and multiple consecutive SBFD time slots; or the first resource can be evenly deployed in multiple locations of multiple consecutive uplink time slots and multiple consecutive SBFD time slots.

[0137] It should be noted that the presence of multiple consecutive uplink time slots / multiple consecutive SBFD time slots indicates that the external interference situation is relatively stable, and the configuration of the first resource can be appropriately reduced to reduce the impact on uplink throughput.

[0138] It should be noted that the configuration methods of the first resource differ between the uplink time slot and the SBFD time slot according to the time slot type within the cycle. This is because the cross-link interference (CLI) situation varies for different time slot types. For example, the uplink time slot is full-bandwidth uplink, so the corresponding first resource can be configured on the uplink time slot according to the time-frequency pattern of the pilot signal of the adjacent base station. However, since the SBFD time slot has a UL subband and is transmitted together with adjacent base stations under the same operator, it generally only needs to reserve an empty RE for measuring leakage interference. Therefore, the configuration method of the first resource can be distinguished according to the time slot type.

[0139] In some embodiments, the bias configuration information includes any one of the following: one or more first time slot indices; first time slot mapping information.

[0140] As an example, the network device indicates the time domain location of the first time slot within a period through one or more first time slot indices in the bias configuration information. For the uplink time slot / SBFD time slot, since the corresponding index is pre-edited for each time slot in the uplink time slot / SBFD time slot within the period, the first time slot can be indicated by one or more first time slot indices; for example, if the one or more first time slot indices included in the bias configuration information are indices 3 and 7, then the uplink time slot / SBFD time slot with indices 3 and 7 within the period is the first time slot.

[0141] In another example, the network device indicates the time domain position of the first time slot within a period through the first time slot mapping information in the bias configuration information. Since the number of bits in the first time slot mapping information bitmap is the same as the number of time slots in the uplink time slot / SBFD time slot within the period, each bit in the first time slot mapping information bitmap corresponds to one uplink time slot / one SBFD time slot. A bit value of 1 indicates that the corresponding uplink time slot / SBFD time slot is occupied by the first resource and is the first time slot, while a bit value of 0 indicates that the corresponding uplink time slot / SBFD time slot is not occupied by the first resource and is not the first time slot. For example, if the first, third, and fifth bits in the first time slot mapping information bitmap included in the bias configuration information have a bit value of 1, and the remaining bits have a bit value of 0, then the three uplink time slots / SBFD time slots corresponding to the first, third, and fifth bits are the first time slots.

[0142] In some embodiments, the time-domain unit is at least any one of the following: millisecond; frame; subframe; time slot; symbol.

[0143] For example, a network device repeatedly configures the first resource within a period of N time-domain units. The time-domain unit can be milliseconds (ms), frames, subframes, slots, or symbols. Within a period, the first resource can be configured on one or more slots according to the slot type. The slot position of the first resource in each period can be configured through slot type and offset configuration information.

[0144] In some embodiments, frequency domain indication information is used to indicate that the first resource occupies one or more consecutive or discrete subcarriers or one or more resource elements in the first resource block.

[0145] It should be noted that since each resource block RB typically includes 12 subcarriers / REs, after the network device indicates at least one first resource block RB on the bandwidth occupied by the first resource based on the bandwidth indication information, it can also indicate one or more resource elements RE on each first resource block RB by the frequency domain indication information.

[0146] In some embodiments, the frequency domain indication information includes any one of the following: an index of one or more subcarriers, or an index of one or more resource elements; an index of the starting subcarrier and the number of subcarriers of one or more subcarriers, or an index of the starting resource element and the number of resource elements of one or more resource elements; mapping information of one or more subcarriers, or mapping information of one or more resource elements; a comb mapping interval value of one or more subcarriers, or a comb mapping interval value of one or more resource elements.

[0147] As an example, the index of one or more subcarriers or REs included in the frequency domain indication information is used to indicate the location of at least one subcarrier or at least one RE on each first resource block RB. Since each resource block RB typically includes 12 subcarriers / REs, and each subcarrier / RE has its own corresponding index, the location of at least one subcarrier or at least one RE on each first resource block RB can be indicated by one or more subcarrier or RE indices. For example, if the index of one or more subcarriers or REs included in the frequency domain indication information is index 1, 3, and 5, then the first resource occupies the subcarriers or REs with indices 1, 3, and 5 in each first resource block RB.

[0148] In another example, the index of the starting subcarrier or RE, and the number of subcarriers or REs included in the frequency domain indication information are used to indicate the position of at least one subcarrier or at least one RE on each first resource block RB. Since each resource block RB typically includes 12 subcarriers / REs, and each subcarrier / RE has its own corresponding index, the starting subcarrier index or starting RE index can be used to indicate the starting subcarrier or starting RE in each first resource block RB, and the number of subcarriers or REs in each first resource block RB can be indicated by the number of subcarriers or REs in each first resource block RB. For example, if the starting subcarrier or RE index included in the frequency domain indication information is 2 and the number of subcarriers or REs is 5, then the first resource occupies 5 consecutive subcarriers or REs in each first resource block RB starting with the subcarrier or RE with index 2.

[0149] In another example, the subcarrier or RE mapping information included in the frequency domain indication information is used to indicate the position of at least one subcarrier or at least one RE on each first resource block RB. Since the number of bits in the subcarrier or RE mapping information bitmap is the same as the number of 12 subcarriers / REs typically included on each resource block RB, each bit in the subcarrier or RE mapping information bitmap corresponds to one subcarrier / RE. A bit value of 1 indicates that the corresponding subcarrier / RE is occupied by the first resource, and a bit value of 0 indicates that the corresponding subcarrier / RE is not occupied by the first resource. For example, if the first, third, and eleventh bits of the subcarrier or RE mapping information bitmap included in the frequency domain indication information have a bit value of 1, and the remaining bits have a bit value of 0, then the first resource occupies the three subcarriers / REs corresponding to the first, third, and eleventh bits in each first resource block RB.

[0150] In another example, the comb mapping interval value of the subcarrier or RE included in the frequency domain indication information is used to indicate the position of at least one subcarrier or at least one RE on each first resource block RB; for example, if the comb mapping interval value of the subcarrier or RE included in the frequency domain indication information is 2, then the first resource starts from the first resource block subcarrier or RE on each first resource block RB, and every 2 subcarriers or REs occupy 1 subcarrier or RE.

[0151] In some embodiments, time-domain indication information is used to indicate one or more consecutive or discrete symbols in a first time slot for the first resource to occupy.

[0152] It should be noted that since each first time slot typically includes multiple symbols, after the network device indicates the first time slot within the first resource occupancy period based on the periodic indication information, it can also indicate one or more symbols in each first time slot for the first resource occupancy through the time domain indication information.

[0153] In some embodiments, the time-domain indication information includes any one of the following: an index of one or more symbols; an index of the starting symbol of one or more symbols and the number of symbols; mapping information of one or more symbols; and comb mapping interval values ​​of one or more symbols.

[0154] As an example, the index of one or more symbols included in the time-domain indication information is used to indicate the symbol position of one or more symbols in each first time slot occupied by the first resource. Since the corresponding index is pre-edited for each symbol in the first time slot, the index of one or more symbols can be used to indicate that the first resource occupies one or more symbols in the first time slot; for example, if the index of one or more symbols included in the time-domain indication information is index 0, 5 and 9 respectively, then the first resource occupies the symbols with indices 0, 5 and 9 in each first time slot.

[0155] In another example, the index of the starting symbol and the number of symbols included in the time-domain indication information are used to indicate the symbol position of one or more symbols in each first time slot occupied by the first resource. Since the corresponding index is pre-edited for each symbol in the first time slot, the starting symbol occupied by the first resource in each first time slot and the number of symbols occupied by the first resource in each first time slot can be indicated by the index of the starting symbol and the number of symbols occupied by the first resource in each first time slot. For example, if the starting symbol index included in the time-domain indication information is 0 and the number of symbols is 6, then the first resource occupies 6 consecutive symbols in each first time slot starting with the symbol with index 0.

[0156] In another example, the mapping information of one or more symbols included in the time-domain indication information is used to indicate the symbol positions of one or more symbols occupied by the first resource in each first time slot. Since the number of bits in the mapping information bitmap of one or more symbols is the same as the number of symbols included in each first time slot, each bit in the mapping information bitmap of one or more symbols corresponds to one symbol. A bit value of 1 indicates that the corresponding symbol is occupied by the first resource, and a bit value of 0 indicates that the corresponding symbol is not occupied by the first resource. For example, if the first, third, and fifth bits of the mapping information bitmap of one or more symbols included in the time-domain indication information have a bit value of 1, and the remaining bits have a bit value of 0, then the first resource occupies the three symbols corresponding to the first, third, and fifth bits in each first time slot.

[0157] In another example, the comb mapping interval value of one or more symbols included in the time domain indication information is used to indicate the symbol position of one or more symbols in each first time slot occupied by the first resource; for example, if the comb mapping interval value of one or more symbols included in the time domain indication information is 3, then the first resource starts from the first symbol in each first time slot, and 1 symbol is occupied for every 2 symbols.

[0158] It is understandable that the first resource, which arranges multiple discrete symbols in each time slot, can accurately measure the interference situation at any time, which is beneficial to the accurate reception of the uplink channel. In particular, when scheduling multiple PUSCH channels in one time slot, it can accurately grasp the interference situation of each uplink channel.

[0159] It should be noted that the network device indicates the location of the RE occupied by the first resource within a first time slot through frequency domain indication information and time domain indication information; wherein, in order to facilitate interference measurement, the network device supports configuring frequency domain indication information and time domain indication information based on the pilot signals of neighboring base stations.

[0160] For example, if the pilot signal is CSI-RS, the position of CSI-RS within a time slot is defined by TS38211 Table 7.4.1.5.3-1, as shown in Figure 18. This is the network device configuring the first resource on the corresponding RE based on the CSI-RS configuration method in the first row of TS38211 Table 7.4.1.5.3-1. As shown in Figure 19, this is the network device configuring the first resource on the corresponding RE based on the CSI-RS configuration method in the eighth row of TS38211 Table 7.4.1.5.3-1.

[0161] It should be noted that after configuring the first resource, the network device can directly measure the interference covariance matrix using the first resource. The first resource can occupy multiple discrete or continuous REs on multiple symbols within a first time slot.

[0162] As shown in Figure 20, the network device configures the RE occupancy of the first resource on two discrete symbols based on a comb mapping interval of 2; as shown in Figure 21, the network device configures the RE occupancy of the first resource on two consecutive symbols based on a comb mapping interval of 2 for one or more symbols; as shown in Figure 22, the network device configures the RE occupancy of the first resource on two more distant discrete symbols based on a comb mapping interval of 2. Thus, it is possible to schedule PUSCHs at any location within a time slot to perform interference measurement to ensure accurate reception, and it is also possible to accurately grasp the interference situation of each uplink channel when scheduling two PUSCHs.

[0163] It should be noted that Figures 20-22 show a method of uniformly configuring the first resource on the symbol. This uniform configuration can be accomplished by the RE comb mapping interval value mentioned above. Furthermore, the uniform configuration of the first resource can also be accomplished by the starting RE index and the number of REs mentioned above. In addition, for discrete non-uniform RE occupancy, it can be accomplished by one or more RE indices mentioned above, or by RE mapping information.

[0164] In some embodiments, the number of sets of configuration information for at least one first resource is related to the number of time slot types.

[0165] For example, if the number of time slot types is 2, including uplink time slots and SBFD time slots, then the first information includes the configuration information of 2 sets of first resources, namely, the configuration information of one set of first resources corresponding to the uplink time slot and the configuration information of one set of first resources corresponding to the SBFD time slot.

[0166] In some embodiments, the configuration information for each group of first resources is different, or partially different.

[0167] For example, for the uplink time slot and the SBFD time slot, the configuration information of each group of first resources contains bandwidth indication information for indicating the bandwidth of the first resource, period indication information for indicating the period of the first resource, frequency domain indication information for indicating the subcarrier or RE occupied by the first resource, and time domain indication information for indicating the symbol occupied by the first resource. The bandwidth indication information, period indication information, frequency domain indication information, and time domain indication information corresponding to the uplink time slot and the SBFD time slot are different or partially different.

[0168] In some embodiments, the number of first resources is one or more, and each of the multiple first resources occupies one or more of the following: subcarriers or REs, symbols, bandwidth, and periods.

[0169] For example, for the uplink time slot and the SBFD time slot, since the bandwidth indication information, period indication information, frequency domain indication information, and time domain indication information corresponding to the uplink time slot and the SBFD time slot are different or partially different, when the network device configures the first resource on the uplink time slot and the SBFD time slot respectively, the subcarrier or RE, symbol, bandwidth, and period occupied by the first resource corresponding to the uplink time slot and the SBFD time slot are different, one or more of these will be different.

[0170] In some embodiments, the first information is included in one or more of the following signaling: Radio Resource Control (RRC) signaling; Downlink Control (DCI) signaling; and Media Access Control (MAC) CE signaling.

[0171] For example, a network device sends out first information via RRC signaling. The first information is used to indicate the first resource for interference measurement. The network device can configure multiple sets of configuration information for the first resource via RRC signaling. That is, multiple time-frequency configuration methods may occur within one cycle of actual transmission, which supports both the measurement of interference covariance and the measurement of pilot signals.

[0172] In another example, the network device sends first information via DCI signaling or MAC CE signaling. The first information is used to indicate the first resource for interference measurement. Considering that the transmission of the pilot signal may be aperiodic or semi-continuous, the network device may also specify the first resource on one or more time slots via DCI signaling or MAC CE signaling.

[0173] In some embodiments, the terminal device receives a downlink channel and / or a downlink signal on a first resource, the downlink channel and / or the downlink signal being used for interference measurement.

[0174] Understandably, network devices send first information via higher-layer signaling or downlink control signaling. Terminals determine the first resource based on this information and enable uplink silencing for resources overlapping with their own uplink channel resources within the first resource, i.e., they do not perform uplink transmission on these overlapping resources. Since the resources used by the terminal device to transmit PUSCH are indicated semi-statically or dynamically by the network device, the network device knows the location of the enabled uplink silencing resources. Therefore, the network device and the terminal device can perform interference measurements on the first resource. The terminal device receives downlink channels and / or downlink signals on this first resource and measures the interference covariance using the downlink channels and / or downlink signals, or correlates the received downlink channels and / or downlink signals with pilot signal sequences from adjacent base stations to measure interference power. If no uplink channel scheduling is performed on this first resource, then interference measurements on this first resource will not affect the accurate estimation of cross-link interference, and since there is no uplink transmission, it will not affect the uplink throughput.

[0175] In summary, according to the channel transmission method of this application embodiment, the terminal device can determine the first resource pre-configured by the network device for interference measurement based on the first information sent by the network device. When the first resource for interference measurement overlaps with the resource for uplink channel transmission, the transmission rules of the uplink channel are changed. That is, if there is no uplink channel transmission on the first resource, interference measurement can be performed directly. If there is uplink channel transmission, the overlapping resource is muted. Based on this, the terminal device can measure the interference situation at any time, thereby obtaining more accurate interference measurement results. The first resource can also correspond to various time-frequency resource mappings of pilot signals from adjacent base stations, which can support the measurement of interference covariance in the presence of empty REs and the measurement of pilot signals, thereby improving the overall resource utilization rate.

[0176] The channel transmission method of this embodiment of the invention has been described in detail above from the perspective of the terminal device with reference to Figure 6. The channel transmission method of this embodiment of the invention will be described in detail below from the perspective of the network device with reference to Figure 23. It should be understood that the steps performed by the network device correspond to the steps performed by the terminal device. For the sake of brevity, repeated descriptions will be omitted appropriately below.

[0201] In some embodiments, the number of first resources is one or more, and each of the multiple first resources occupies one or more of the following: subcarriers or resource elements, symbols, bandwidth, and periods.

[0202] In some embodiments, the time slot type is at least any one of the following: uplink time slot; SBFD time slot.

[0203] In some embodiments, the first information is included in one or more of the following signaling: Radio Resource Control (RRC) signaling; Downlink Control (DCI) signaling; and Media Access Control (MAC) CE signaling.

[0204] In some embodiments, the reference signal includes any one of the following: demodulation reference signal DMRS; probe reference signal SRS; enhanced probe reference signal E-SRS; phase tracking reference signal PTRS.

[0205] In some embodiments, the first information relates to the resource configuration of downlink channels and / or downlink signals used for interference measurement.

[0206] As an example, in order to measure the interference caused by downlink transmissions from adjacent base stations, a network device may generate first information based on the resource configuration of the downlink channel and / or downlink signal used for measuring the interference from adjacent base stations. The first information is used to indicate the first resource. For example, the network device generates the first information based on the resource configuration of the pilot signal CSI-RS of adjacent base stations.

[0207] In some embodiments, the network device transmits downlink channels and / or downlink signals on a first resource.

[0208] Understandably, network devices send first information via higher-layer signaling or downlink control signaling. Terminals determine the first resource based on this first information and enable uplink silencing for resources overlapping with their own uplink channel resources within the first resource, i.e., they do not perform uplink transmission on these overlapping resources. Since the resources used by the terminal device to transmit PUSCH are indicated semi-statically or dynamically by the network device, the network device knows the location of the enabled uplink silencing resources. Therefore, the network device and the terminal device can perform interference measurements on the first resource. The terminal device receives downlink channels and / or downlink signals on this first resource and measures the interference covariance using the downlink channels and / or downlink signals, or correlates the received downlink channels and / or downlink signals with pilot signal sequences from adjacent base stations to measure interference power. If no uplink channel scheduling is performed on this first resource, then interference measurements on this first resource will not affect the accurate estimation of cross-link interference, and since there is no uplink transmission, it will not affect the uplink throughput.

[0209] In summary, according to the channel transmission method of this application embodiment, the terminal device can determine the first resource pre-configured by the network device for interference measurement based on the first information sent by the network device. When the first resource for interference measurement overlaps with the resource for uplink channel transmission, the transmission rules of the uplink channel are changed. That is, if there is no uplink channel transmission on the first resource, interference measurement can be performed directly. If there is uplink channel transmission, the overlapping resource is muted. Based on this, the terminal device can measure the interference situation at any time, thereby obtaining more accurate interference measurement results. The first resource can also correspond to various time-frequency resource mappings of pilot signals from adjacent base stations, which can support the measurement of interference covariance in the presence of empty REs and the measurement of pilot signals, thereby improving the overall resource utilization rate.

[0210] The channel transmission method provided in the embodiments of this application has been introduced above. To facilitate understanding of the embodiments of this application, the following describes possible implementation schemes of the channel transmission method applicable to the embodiments of this application based on the interaction process between network devices and terminal devices.

[0211] Step 1: The network device sends a pre-configured silent resource indication (first information) via higher-layer signaling or downlink control signaling.

[0212] It should be noted that the pre-configured silent resource indication is used to indicate the pre-configured silent resource (first resource). The pre-configured silent resource indication may be related to the resource configuration of the pilot signal of the adjacent base station, or it may be unrelated and directly indicated by the network device. This application embodiment does not limit this.

[0213] Step 2: The terminal device receives the pre-configured silent resource indication (first information) and determines, according to the pre-configured silent resource indication (first information), that some resources in the uplink channel resources for transmitting the uplink channel are silent resources and no uplink transmission is performed on these resources.

[0214] Among them, some resources are not only resources in the uplink channel resources, but also resources in the pre-configured silent resources (first resources). That is, some resources are resources in the overlapping resources of the uplink channel resources and the pre-configured silent resources (first resources). The pre-configured silent resources (first resources) include one or more symbols and / or one or more REs on one or more symbols.

[0215] Some resources do not include reference signal resources (third resources) in the uplink channel resources. If the pre-configured silence resources (first resources) include some reference signal resources, then the uplink resource silence is not enabled for these reference signal resources. The reference signals include, but are not limited to, at least one of the following: demodulation reference signal (DMRS), sounding reference signal (SRS), enhanced SRS (E-SRS), and phase tracking reference signal (PTRS).

[0216] The pre-configured silent resource indication (first information) includes at least one set of time-frequency pattern configuration information (configuration information of the first resource). Each set of time-frequency pattern configuration information (configuration information of the first resource) includes at least frequency domain configuration information (frequency domain indication information), time domain configuration information (time domain indication information), bandwidth configuration information (bandwidth indication information), and period configuration information (period indication information). Each set of time-frequency pattern configuration information (configuration information of the first resource) is different or partially different.

[0217] The time-domain configuration information (time-domain indication information) indicates the subcarrier position occupied by the silent resource (first resource) within an RB. The silent resource (first resource) can occupy one or more REs on an RB, and the multiple occupied REs can be continuous or discrete.

[0218] The frequency domain configuration information (frequency domain indication information) indicates the symbol position of the silent resource (first resource) within a time slot. The silent resource (first resource) can occupy one or more symbols within a time slot, and the occupied symbols can be continuous or discrete.

[0219] The periodic configuration information (period indication information) is used to indicate the configuration period of the time-frequency pattern, including: the time-frequency pattern spoiler periodicity, which is repeatedly configured with Q time domain units as the period. The time domain units can be milliseconds (ms), frames, subframes, slots, or symbols. At least one time-frequency pattern can be configured on a slot in each period. The slot position of the silent resource (first resource) in each period can be indicated by configuring offset configuration information.

[0220] Within a period, one or more time slots can be configured with silent resources (first resources) according to the time slot type. Each time slot type can correspond to a set of time-frequency pattern configuration information.

[0221] As an example, the uplink slot and SBFD slot can have the same or different configurations depending on the slot type:

[0222] 1. A silent resource (first resource) is configured for each uplink slot and / or SBFD slot within the period.

[0223] Optionally, a silent resource (first resource) may be configured only on each uplink slot, or only on each SBFD slot, or both uplink slots and SBFD slots may be configured with a silent resource (first resource).

[0224] 2. If there are M consecutive uplink time slots and / or SBFD time slots within a period, select one or more of these time slots to configure silent resources (first resources).

[0225] Optionally, a silent resource (first resource) may be configured on one or more uplink time slots among the M uplink time slots only when there are M consecutive uplink time slots; or, a silent resource may be configured on one or more SBFD time slots among the M SBFD time slots only when there are M consecutive SBFD time slots; or, a silent resource may be configured on one or more uplink time slots and / or SBFD time slots when there are M consecutive uplink time slots and SBFD time slots.

[0226] The bandwidth configuration information (bandwidth indication information) is used to indicate the bandwidth occupied by the silent resource (first resource). Similarly, the same or different configurations can exist on the uplink time slot and SBFD time slot according to different time slot types.
