Description

Technical Field

[0001] The embodiments of the present application relate to the field of communications, and in particular to a method and device for configuring measurement resources. Background Art

[0002] In order to improve the uplink coverage and reduce the uplink delay in the mobile communication system, a subband full duplex (SBFD) duplex mode can be used. In SBFD, the frequency band on the downlink symbol can be divided into an uplink subband and a downlink subband, allowing uplink transmission on the uplink subband of the downlink symbol.

[0003] In addition, the mobile communication system also supports dynamic / flexible time division duplex (TDD). Dynamic / flexible TDD supports different uplink and downlink time slot ratios in different cells and supports dynamic changes in uplink and downlink time slot ratios.

[0004] However, SBFD and dynamic / flexible TDD will introduce cross link interference (CLI) between base stations, and base stations need to perform CLI measurements. Therefore, how to configure CLI measurement resources is an urgent problem to be solved. Summary of the invention

[0005] The embodiments of the present application provide a method and device for configuring measurement resources, which can flexibly configure the time domain location of CLI measurement resources, thereby improving CLI measurement performance.

[0006] In a first aspect, a method for configuring measurement resources is provided, which can be executed by a first network device, or by a component of the first network device, such as a processor, a chip, or a chip system of the first network device, or can be implemented by a logic module or software that can implement all or part of the functions of the first network device. The method includes: sending a first message to a first terminal device, wherein the first message indicates a first resource, and the first resource is used for cross-link interference CLI measurement. CLI is measured on the first resource. The first resource is a time domain periodic resource, and / or the first resource is located within a first time domain range, the first time domain range is the time domain position of a physical uplink shared channel PUSCH within a time unit, or the first time domain range is the time domain position corresponding to each frequency hop within the PUSCH.

[0007] Based on this solution, the first resource (i.e., the CLI measurement resource) can be a time domain periodic resource, so that the network device can flexibly configure the period of the first resource, the time unit and sub-time unit, etc., to improve the CLI measurement performance. Alternatively, the first resource can be located in the time domain position of the PUSCH within a time unit, so that the network device can flexibly configure the first resource in the time domain position of the PUSCH to avoid duplication of the first resource with the DMRS and / or UCI, thereby improving the CLI measurement performance. Alternatively, the first resource can be located in the time domain position corresponding to each frequency hop in the PUSCH, so that there is a CLI measurement resource in the time domain position corresponding to each frequency hop, so that CLI measurement can be performed before and after each frequency hop, thereby improving the CLI measurement performance.

[0008] In one possible design, the method further includes: sending second information to the first terminal device, the second information indicating a second resource, the second resource being a resource where the PUSCH is located. Receiving a first signal from the first terminal device on a third resource, the third resource being a resource in the second resource that does not overlap with the first resource.

[0009] In the second aspect, a method for configuring measurement resources is provided, which can be executed by a first terminal device, or by a component of the first terminal device, such as a processor, a chip, or a chip system of the first terminal device, or can be implemented by a logic module or software that can implement all or part of the functions of the first terminal device. The method includes: receiving first information from a first network device, the first information indicating a first resource, and the first resource is used for cross-link interference CLI measurement. Sending a first signal to the first network device on a third resource, the third resource does not include the first resource. Among them, the first resource is a time domain periodic resource, and / or the first resource is located within a first time domain range. The first time domain range is the time domain position of the physical uplink shared channel PUSCH within a time unit, or the first time domain range is the time domain position corresponding to each frequency hop within the PUSCH.

[0010] Based on this scheme, the first resource (i.e., the CLI measurement resource) can be a time domain periodic resource, so that the network device can flexibly configure the period of the first resource, the time unit and sub-time unit, etc., to improve the CLI measurement performance. Alternatively, the first resource can be located in the time domain position of the PUSCH within a time unit, so that the network device can flexibly configure the first resource in the time domain position of the PUSCH, avoid duplication of the first resource with the DMRS and / or UCI, and improve the CLI measurement performance. Alternatively, the first resource can be located in the time domain position corresponding to each frequency hop in the PUSCH, so that there is a CLI measurement resource in the time domain position corresponding to each frequency hop, so that CLI measurement can be performed before and after each frequency hop, thereby improving the CLI measurement performance. In addition, the third resource does not include the first resource, that is, the terminal device does not send an uplink signal on the first resource, which can reduce the interference of the uplink signal on the CLI measurement and improve the CLI measurement performance.

[0011] In one possible design, the method also includes: receiving second information from the first network device, the second information indicating a second resource, the second resource being a resource where the PUSCH is located, and the third resource being a resource in the second resource that does not overlap with the first resource.

[0012] In combination with the first aspect or the second aspect, in one possible design, the first resource is a time domain periodic resource, and the first information indicates at least one of the following: a period of the first resource, an offset, or a sub-time unit in which the first resource is located. The offset is used to indicate the time unit in which the first resource is located, and the time unit includes at least one sub-time unit.

[0013] Based on this possible design, the network device can flexibly configure at least one of the period, the time unit, and the sub-time unit of the first resource, thereby improving the flexibility of CLI measurement resource configuration.

[0014] In combination with the first aspect or the second aspect, in a possible design, the first information includes a first bitmap or a second bitmap. The first bitmap includes X bits, and the X bits correspond one-to-one to the X sub-time units in the time unit where the first resource is located. Among the X bits, the sub-time unit corresponding to the bit with the first numerical value is the sub-time unit where the first resource is located, and X is the total number of sub-time units included in the time unit where the first resource is located. The second bitmap includes Y bits, and the Y bits correspond one-to-one to the Y sub-time units in the time unit where the first resource is located. The Y sub-time units do not include the sub-time unit used to carry the non-demodulation reference signal DMRS. Among the Y bits, the sub-time unit corresponding to the bit with the first numerical value is the sub-time unit where the first resource is located, and Y is a positive integer.

[0015] In combination with the first aspect or the second aspect, in a possible design, the time domain position of the PUSCH within a time unit includes: the time domain position repeated in each time unit in PUSCH repetition type A, the time domain position actually repeated in each time unit in PUSCH repetition type B, or the time domain position of a transmission block TB across multiple time units in each time unit.

[0016] Based on this possible design, CLI measurement in various PUSCH transmission scenarios can be flexibly supported. In the case where PUSCH transmission involves multiple time units, CLI measurement resources can be present in each time unit or each actually repeated time domain position, so that the network device can perform CLI measurement in each time unit or each actually repeated time domain position, thereby improving the accuracy of the measurement.

[0017] In combination with the first aspect or the second aspect, in one possible design, the first information indicates N sub-time units within a first time domain range, the N sub-time units are the sub-time units where the first resource is located, and N is a positive integer.

[0018] Based on this possible design, the network device can flexibly indicate the sub-time unit where the first resource is located, thereby improving the flexibility of CLI measurement resource configuration.

[0019] In combination with the first aspect or the second aspect, in a possible design, the time domain position of the first resource satisfies at least one of the following:

[0020] The first sub-time unit within the first time domain range that is not used to carry a non-demodulation reference signal DMRS;

[0021] The first sub-time unit within the first time domain that is not used to carry uplink control information UCI;

[0022] The first sub-time unit in the first time domain range that is not used to carry DMRS and is not used to carry UCI;

[0023] The first sub-time unit not used for carrying DMRS after the first sub-time unit used for carrying DMRS in the first time domain range;

[0024] The first sub-time unit not used to carry UCI after the first sub-time unit used to carry UCI in the first time domain range;

[0025] The first sub-time unit not used for carrying DMRS and not used for carrying UCI after the first sub-time unit used for carrying DMRS in the first time domain range;

[0026] A first sub-time unit that is not used to carry DMRS and is not used to carry UCI after the first sub-time unit that is used to carry UCI in the first time domain range.

[0027] In combination with the first aspect or the second aspect, in a possible design, the time domain position of the first resource does not overlap with the time domain position of the fourth resource; the fourth resource is used to carry DMRS, and / or the fourth resource is used to carry UCI.

[0028] In combination with the first aspect or the second aspect, in one possible design, the first information indicating the first resource includes: the first information indicating a fifth resource, and the fifth resource is used for CLI measurement. The first resource includes a resource in the fifth resource that does not overlap with the fourth resource; the fourth resource is used to carry DMRS, and / or the fourth resource is used to carry UCI.

[0029] In combination with the first aspect or the second aspect, in a possible design, the first resource also includes M sub-time units after the fifth resource, where M is the number of sub-time units occupied by the fourth resource.

[0030] Based on the above four possible designs, it is possible to ensure that the resources actually used for CLI measurement do not overlap with the time domain position of DMRS and / or UCI, thereby avoiding the impact of CLI measurement on DMRS and / or UCI, reducing the impact of CLI measurement on uplink data demodulation and / or UCI transmission, and improving the transmission performance of uplink data and / or UCI.

[0031] In combination with the first aspect or the second aspect, in a possible design, the UCI satisfies at least one of the following:

[0032] UCI is hybrid automatic repeat request confirmation HARQ-ACK information;

[0033] UCI includes HARQ-ACK information and channel state information reference signal CSI-RS part 1;

[0034] UCI includes HARQ-ACK information, CSI-RS part 1, and joint coding of HARQ-ACK and configuration grant UCI;

[0035] UCI includes HARQ-ACK information, CSI-RS part 1, CSI-RS part 2, configuration grant UCI, and joint coding of HARQ-ACK and configuration grant UCI;

[0036] UCI is the joint coding of HARQ-ACK and CG-UCI;

[0037] UCI includes HARQ-ACK information and joint coding of HARQ-ACK and CG-UCI.

[0038] In combination with the first aspect or the second aspect, in a possible design, the first resource occupies P resource elements RE in a resource block RB, and the index difference between any two adjacent REs among the P REs is Q / P, where Q is the total number of REs included in the RB, and P and Q are positive integers.

[0039] In combination with the first aspect or the second aspect, in a possible design, an index i of a resource element RE occupied by the first resource in a resource block RB satisfies:

[0040] i=nL+k

[0041] Where L is a divisor of Q, Q is the number of REs included in RB; k is one of 0, 1, ..., L-1, L is an integer greater than 1.

[0042] Based on the above two possible designs, the REs occupied by the first resource can be distributed in a comb-teeth manner, so that the REs not used for the first resource can be used to carry other signals, thereby improving resource utilization.

[0043] In combination with the first aspect or the second aspect, in one possible design, the method also includes: sending third information to the second network device, where the third information indicates the first resource.

[0044] Based on this possible design, the first network device indicates the first resource to the second network device, so that the second network device can use the same resource to perform CLI measurement, so that there may be no uplink signal sent by the terminal device to the network device on the measurement resource (such as the first resource), thereby reducing the impact on the CLI measurement between base stations and improving the accuracy of the CLI measurement.

The module or unit may be implemented by hardware, software, or by hardware executing corresponding software implementation.

[0047] In some possible designs, the transceiver module may be composed of a transceiver circuit, a transceiver, a transceiver or a communication interface.

[0048] In a fourth aspect, a communication device is provided, the communication device comprising a processor, the processor being configured to execute any of the methods described in the first aspect or the second aspect. The processor may be one or more. The communication device may also include a memory, the memory being used to store computer instructions, and when the processor executes the instructions, the communication device executes any of the methods described in the first aspect or the second aspect.

The following description of the implementation methods of this application does not constitute a limitation on the scope of protection of this application.

[0083] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the related technologies of the present application is first given as follows.

[0084] 1. Subband full duplex (SBFD):

[0085] Time division duplex (TDD) is widely used in the fifth generation (5G) mobile communication system. TDD separates transmission and reception in the time domain, dividing the time domain resources into uplink resources and downlink resources. The terminal device transmits on the uplink resources and receives on the downlink resources.

[0086] For example, Figure 1As shown, a possible TDD uplink and downlink time slot ratio is DDDSU. Among them, D represents the downlink time slot, U represents the uplink time slot, and S identifies the special time slot. Each orthogonal frequency division multiplexing (OFDM) symbol (hereinafter referred to as symbol) in the downlink time slot is a downlink symbol, which is used for downlink transmission. Each symbol in the uplink time slot is an uplink symbol, which is used for uplink transmission. Special time slots include at least flexible symbols, which can be used for both downlink transmission and uplink transmission.

[0087] In the commonly used TDD uplink and downlink time slot ratio, the uplink time domain resources are usually less, which will lead to reduced uplink coverage and increased latency of TDD. A possible uplink enhancement method is to use SBFD.

[0088] SBFD divides the frequency band on the downlink symbol into at least one uplink subband and at least one downlink subband, allowing the terminal device to perform uplink transmission on the uplink subband of the downlink symbol. Among them, the subbands in SBFD may or may not overlap, and this application does not make specific restrictions on this.

[0089] For example, Figure 2 As shown, in a certain time slot, subband 1 and subband 2 can be divided in the frequency domain, allowing downlink transmission on subband 1 and uplink transmission on subband 2.

[0090] Currently, the base station supports full duplex (FD) SBFD, that is, the base station can simultaneously receive in the uplink subband and transmit in the downlink subband in one time slot. The terminal device supports half duplex (HD) SBFD, that is, the terminal device can only transmit in the uplink subband or only receive in the downlink subband in one time slot.

[0091] 2. Dynamic / Flexible TDD:

[0092] Dynamic / flexible TDD supports different uplink and downlink time slot ratios in different cells, and supports dynamic changes in uplink and downlink time slot ratios. For example, Figure 3 As shown, the uplink and downlink time slot ratio used by cell 1 is DDDSU, and the uplink and downlink time slot ratio used by cell 2 is DSUUU.

[0093] 3. Cross link interference (CLI):

[0094] CLI can be understood as interference between communication links in opposite directions, such as interference from an uplink to a downlink, or from a downlink to an uplink.

[0095] In SBFD or dynamic TDD mechanisms, CLI between base stations is usually introduced. For example, the downlink signal sent by base station 1 interferes with the uplink signal received by base station 2. It should be noted that, unless otherwise specified, the CLI in the following embodiments of the present application refers to CLI between base stations or CLI between network devices.

[0096] For example, Figure 2 As shown in the figure, assuming that base station 1 sends downlink signal 1 to terminal device 1 on subband 1, and base station 2 receives uplink signal 2 of terminal device 2 on subband 2, the interference caused by downlink signal 1 sent by base station 1 to uplink signal 2 received by base station 2 can be considered as CLI between base stations. In addition, since the base station supports FD SBFD, the downlink signal sent by base station 2 on subband 1 will also generate CLI for the signal received by base station 1 on subband 2.

[0097] Or, if Figure 3 As shown, it is assumed that at the same time, the uplink and downlink time slot ratio used by cell 1 of base station 1 is DDDSU, and the uplink and downlink ratio used by cell 2 of base station 2 is DSUUU. If base station 1 and base station 2 are synchronized, then in time slot 3, the downlink signal sent by base station 1 will generate CLI for the uplink signal received by base station 2.

[0098] Due to the existence of CLI between base stations, it is necessary to measure and compensate the CLI between base stations to suppress the influence of CLI between base stations on uplink communication.

[0099] In a possible implementation, channel state information-interference measurement (CSI-IM) resources may be used to perform CLI measurement between base stations.

[0100] CSI-IM resources are originally used for downlink interference measurement between cells. CSI-IM resources support two time-frequency patterns: pattern 0 and pattern 1. Each time-frequency pattern occupies 4 resource elements (REs), but the time-frequency positions of the two patterns are different. Figure 4 As shown in (a) in FIG. 1 , in pattern 0, the CSI-IM resource occupies two consecutive symbols in the time domain; Figure 4 As shown in (b) in pattern 1, the CSI-IM resource occupies 1 symbol in the time domain.

[0101] It should be noted that in the attached drawings regarding time-frequency resources in the embodiments of the present application, the horizontal axis represents the time domain and the vertical axis represents the frequency domain. They are explained uniformly here and will not be repeated in subsequent embodiments.

[0102] However, if CSI-IM resources are directly used to perform CLI measurements between base stations, the following problems may occur:

[0103] 1) CSI-IM resources may conflict with the time-frequency resources multiplexed with uplink control information (UCI), resulting in reduced UCI multiplexing performance.

[0104] Exemplarily, the cause of this problem is that the CLI measurement between base stations needs to be performed by the base station performing uplink reception, that is, the resources used for CLI measurement can be understood as uplink resources, and UCI is also sent in uplink resources, so there may be a conflict between the two.

[0105] 2) It is not possible to measure the CLI between base stations caused by different downlink channels in the same time slot.

[0106] Usually, the inter-station CLI caused by the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH) are different and need to be measured separately. However, since CSI-IM occupies 1 symbol or 2 consecutive symbols in a time slot, and PDCCH and PDSCH are usually not located on 1 symbol or 2 consecutive symbols. Therefore, it is impossible to measure the inter-station CLI caused by PDCCH and PDSCH in the same time slot.

[0107] In another possible implementation, Figure 5 As shown, the resource for CLI measurement between base stations (hereinafter referred to as CLI measurement resource) can be located in the first symbol in the time slot (such as Figure 5 Alternatively, it may be located at the first symbol after the first demodulation reference signal (DMRS) of the PUSCH (e.g. Figure 5 The symbol 4) in .

[0108] However, when the CLI measurement resource is located at the first symbol in the time slot, the inter-base station CLI caused by the PDCCH may not be measured. For example, the PDCCH may be located at any symbol in the time slot, such as Figure 6 As shown, if the PDCCH is located at symbols 5 and 6 of the time slot, and the CLI measurement resource is located at symbol 0 in the time slot, then the inter-base station CLI caused by the PDCCH cannot be measured due to the different time domain positions of the CLI measurement resource and the PDCCH.

[0109] In addition, for the scenario of frequency hopping in the PUSCH time slot, the frequency domain position of the PUSCH changes before and after the frequency hopping, and the received CLI between base stations will also change. The CLI needs to be re-measured after the frequency hopping. If the CLI measurement resource is only located on the first symbol after the first DMRS of the PUSCH, the CLI between base stations after the frequency hopping cannot be measured.

[0110] For example, Figure 7 As shown, the first DMRS of PUSCH is located at symbol 3, and the first symbol after the first DMRS is symbol 4. Assuming that the frequency domain position of PUSCH is frequency domain position 1 from symbol 0 to symbol 6, and frequency hopping occurs after symbol 6, that is, the frequency domain position of PUSCH is frequency domain position 2 from symbol 7 to 13, then the inter-base station CLI before frequency hopping can only be measured at symbol 4. Since there is no CLI measurement resource at other positions, the inter-base station CLI after frequency hopping cannot be measured.

[0111] In summary, in the above scheme, the number of symbols occupied by the CLI measurement resource in the time domain is fixed or the time domain position is fixed, and the flexibility is low. Based on this, the present application provides a configuration method for measurement resources, which can flexibly set the time domain position of the CLI measurement resource, thereby improving the measurement performance.

[0112] The technical solution provided in the present application can be used in various communication systems, and the communication system can be a third generation partnership project (3GPP) communication system, for example, a fourth generation (4G) long term evolution (LTE) system, a fifth generation (5G) new radio (NR) system, a vehicle to everything (V2X) system, a system of LTE and NR hybrid networking, or a device to device (D2D) system, a machine to machine (M2M) communication system, the Internet of Things (IoT), a non-terrestrial network (NTN), and other next generation communication systems. Alternatively, the communication system may also be a non-3GPP communication system without limitation.

[0113] Among them, the above-mentioned communication system applicable to the present application is only an example, and the communication system applicable to the present application is not limited to this. It is uniformly explained here and will not be repeated below.

[0114] See also Figure 8, is an exemplary communication system provided by the present application. The communication system includes a first network device and a first terminal device. There is uplink transmission between the first network device and the first terminal device.

[0115] Optionally, the communication system may further include a second network device and a second terminal device. Downlink transmission exists between the second network device and the second terminal device. The second network device may be understood as a neighboring station of the first network device. Alternatively, the first network device may be understood as a neighboring station of the second network device.

[0116] Furthermore, the communication system may also include a third terminal device and a fourth terminal device. The third terminal device is a terminal device served by the first network device, and there may be downlink transmission between the two. The fourth terminal device is a terminal device served by the second network device, and there may be uplink transmission between the two.

[0117] In a possible implementation scenario, downlink transmission between the second network device and the second terminal device interferes with the first network device receiving an uplink signal of the first terminal device, that is, there is an inter-base station CLI between the first network device and the second network device.

[0126] The following will be combined with the accompanying drawings to Figure 8 Taking the interaction between the network device and the terminal device shown as an example, the configuration method of the measurement resources provided in the embodiment of the present application is described in detail.

[0127] It is understandable that in the embodiment of the present application, the network device or terminal device may perform some or all of the steps or operations in the embodiment of the present application, and these steps or operations are only examples. The embodiment of the present application may also perform other steps or operations or variations of each step or operation.

For example, when the first network device is CU, DU or RU, only some of the steps or operations performed by the first network device described in the embodiment of the present application may be performed, and other operations are performed by at least one other network device.

[0128] It should be noted that the message names between the devices or the names of the parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in the specific implementation, and the embodiments of the present application do not specifically limit this.

[0129] like Fig. 9 As shown, it is a flow chart of a method for configuring measurement resources provided in an embodiment of the present application, and the method for configuring measurement resources includes the following steps:

[0130] S901: A first network device sends first information to a first terminal device. Correspondingly, the first terminal device receives the first information from the first network device.

[0131] The first information indicates a first resource, and the first resource is used for CLI measurement. Specifically, the first resource is used for CLI measurement between base stations (or called CLI between network devices).

[0132] In a possible implementation, the first resource is a time domain periodic resource. That is, the first resource is periodically repeated in the time domain. Exemplarily, the repetition period of the first resource may be in units of time slots, symbols, etc., or in units of duration (such as milliseconds (ms), etc.).

[0133] In another possible implementation, the first resource is located in a first time domain range. The first time domain range is a time domain position of a PUSCH in a time unit, or the first time domain range is a time domain position corresponding to each frequency hopping in the PUSCH.

[0134] As a possible implementation, the time unit in the embodiment of the present application may further include multiple sub-time units. Exemplarily, the time unit may be a radio frame, a half frame, a subframe, a time slot, a mini-subframe, a mini-time slot, a transmission occasion (TO), etc. The sub-time unit may be a half frame, a subframe, a time slot, an OFDM symbol, etc.

[0135] Optionally, the first information may also indicate that the first terminal device cannot send an uplink signal on the first resource, or indicate that the first terminal device is not allowed to send an uplink signal on the first resource, or indicate that the first resource is not used to carry an uplink signal.

[0136] Since the first resource is used for CLI measurement between base stations, that is, for measuring the interference caused by other network devices (such as the second network device) to the uplink reception of the first network device. Therefore, it is not expected that the first terminal device sends an uplink signal on the first resource. If the first terminal device sends an uplink signal on the first resource, then when performing CLI measurement between base stations on the first resource, the uplink signal of the first terminal device will also exist on the first resource, and the uplink signal will affect the accuracy of CLI measurement between base stations.

[0137] In a possible implementation, the first information may be carried in a radio resource control (RRC) signaling. In this scenario, it can be considered that the first resource is semi-statically configured through the RRC signaling.

[0138] Optionally, when the first information is carried in RRC signaling, the first information may be cell-level information. That is, the first network device may send the first information to all terminal devices in the current cell to indicate the first resource. The current cell may be understood as the current serving cell of the first terminal device.

[0139] In another possible implementation, the first information may be carried in downlink control information (DCI). In this scenario, before the first information, the first network device may configure a first resource set to the first terminal device, and the resources in the first resource set may be used for CLI measurement. The first information may indicate the first resource from the first resource set. The first resource may be one or more resources in the first resource set. When the first information indicates multiple resources in the first resource set, the multiple resources are effective at the same time and are all used for CLI measurement. Exemplarily, the first network device may configure the first resource set to the first terminal device through RRC signaling. That is, the first network device may semi-statically configure the first resource set through RRC signaling, and then dynamically indicate the first resource through DCI.

[0140] Optionally, when the first information is carried in DCI, the first resource set may be cell-level information, that is, the first network device may configure the first resource set for all terminal devices in the current cell.

[0141] When the first network device indicates the first resource or the first resource set to all terminal devices in the current cell, the first network device expects that none of the terminal devices in the current cell will send uplink signals on the first resource or the resources in the first resource set. In this scenario, all terminal devices in the current cell can learn that the first resource or the first resource set is used for CLI measurement, so that the terminal devices may not send uplink signals on the first resource or the resources in the first resource set, reducing the impact on CLI measurement.

[0142] S902: The first network device measures a CLI on a first resource.

[0143] In a possible implementation manner, the first network device measures, on the first resource, the inter-base station CLI caused by the second network device to the first network device.

[0144] As a possible implementation, the second network device may send a downlink signal (recorded as a second signal) to the second terminal device. The first network device may measure the signal quality, signal strength, or covariance matrix of the second signal sent by the second network device to the second terminal device on the first resource, and the signal quality, signal strength, or covariance matrix may be understood as the inter-base station CLI caused by the second network device to the first network device.

[0145] In a possible implementation, the method may further include the following steps:

[0146] S903: The first network device sends second information to the first terminal device. Correspondingly, the first terminal device receives the second information from the first network device.

[0147] The second information indicates the second resource. The second resource is a resource where the PUSCH is located, or in other words, the second resource is used to carry the PUSCH. Exemplarily, the second information may be carried in the DCI or RRC signaling for scheduling the PUSCH.

[0148] In a possible implementation manner, the second resource and the first resource overlap in the time domain and / or frequency domain.

[0149] It should be noted that there is no temporal order between step S903 and step S901. Step S903 may be performed first, and then step S901; or step S901 may be performed first, and then step S903; or steps S901 and S903 may be performed simultaneously. That is, the second information may be sent before, after, or simultaneously with the first information. This application does not make any specific limitation on this.

[0150] Optionally, the first information and the second information may be carried in the same message, or the first information and the second information may be carried in different messages, which is not specifically limited in the present application.

[0151] S904: The first terminal device sends a first signal to the first network device on the third resource. Correspondingly, the first network device receives the first signal from the first terminal device on the third resource.

[0152] The third resource does not include the first resource. The third resource is a resource in the second resource that does not overlap with the first resource.

[0153] In a possible implementation, before step S904, the first terminal device may determine the third resource based on the first information and the second information. Exemplarily, the third resource is a difference set of the second resource and the first resource, that is, the third resource is a resource in the second resource that does not overlap with the first resource. In addition, before step S904, the first network device also needs to determine the third resource, and the determination method is consistent with that of the first terminal device, which will not be repeated here.

[0154] In a possible implementation manner, before step S904, the first terminal device may generate the first signal in the following two ways:

[0155] Method 1: Generate the first signal by rate matching. Exemplarily, in this method, the first terminal device may perform the following steps:

[0156] 1) Determine the total number of coded bits G that can be used for TB transmission according to the size of the third resource.

[0157] Exemplarily, the total number of coded bits may be determined according to the total number of REs included in the third resource, the modulation order of the first signal, and the number of layers (or referred to as the number of transmission layers or the number of streams) of the first signal. For example, the total number of coded bits satisfies the following relationship:

[0158] G=N RE,3 ×Qm×N L

[0159] Among them, N RE,3 represents the total number of REs included in the third resource. Qm represents the modulation order of the first signal. N L Indicates the layer number of the first signal.

[0160] 2) Channel coding and rate matching are performed on the uplink TB according to the total number of coded bits G.

[0161] 3) Map the bit sequence output by rate matching to the third resource.

[0162] Method 2: Generate the first signal by punching. Exemplarily, in method 2, the first terminal device may perform the following steps:

[0163] 1) Determine the total number of coded bits G that can be used for TB transmission according to the size of the second resource.

[0164] Exemplarily, the total number of coded bits may be determined according to the total number of REs included in the second resource, the modulation order of the first signal, and the number of layers (or referred to as the number of transmission layers or the number of streams) of the first signal. For example, the total number of coded bits satisfies the following relationship:

[0165] G=N RE,2 ×Qm×N L

[0166] Among them, N RE,2 represents the total number of REs included in the second resource. Qm represents the modulation order of the first signal. N L Indicates the layer number of the first signal.

[0167] 2) Channel coding and rate matching are performed on the uplink TB according to the total number of coded bits G.

[0168] 3) Mapping the bit sequence output by the rate matching to the second resource.

[0169] 4) Discarding bits on REs in the second resource that overlap with the first resource.

[0170] Optionally, the resource mapping result obtained in step 3) of the above method 1 or step 4) of the above method 2 can be understood as a signal of the first signal in the frequency domain. Afterwards, the first terminal device can convert the resource mapping result into a time domain signal and send it to the first network device.

[0171] It can be understood that, when the second resource and the first resource do not overlap, the third resource is the second resource, and the results of the above-mentioned method 1 and method 2 are the same.

[0172] It should be noted that there is no time sequence between step S904 and step S902. Step S902 may be performed first, and then step S904; or step S904 may be performed first, and then step S902; or step S902 and S904 may be performed simultaneously, and this application does not make any specific limitation on this.

[0173] In a possible implementation, the first network device may further send a downlink signal (referred to as the third signal) to the third terminal device, and accordingly, the third terminal device receives the third signal from the first network device. The fourth terminal device may further send an uplink signal (referred to as the fourth signal) to the second network device, and accordingly, the second network device receives the fourth signal from the fourth terminal device.

[0174] Optionally, the first signal, the second signal, the third signal, and the fourth signal may be transmitted simultaneously, that is, the transmission times or time domain positions of the four signals overlap or are the same.

[0175] In this scenario, the third signal sent by the first network device to the third terminal device may interfere with the second network device receiving the fourth signal, that is, the first network device may also cause inter-base station CLI to the second network device. At this time, the second network device may also measure the inter-base station CLI on the first resource.

[0176] Optionally, after the first network device determines the first resource or the first resource set, it can send third information to the second network device, where the third information indicates the first resource or the first resource set. After receiving the third information, the second network device can send fourth information to the terminal device served by the second network device to indicate the first resource, and can further instruct the terminal device not to send an uplink signal on the first resource.

[0177] Exemplarily, the terminal device served by the second network device may be a third terminal device or all terminal devices in the first cell. The first cell is a service cell for the third terminal device managed by the second network device. In addition, the implementation of the fourth information may refer to the relevant description of the first information, the behavior of the second network device may refer to the relevant description of the first network device, the behavior of the fourth terminal device may refer to the relevant description of the first terminal device, and the behavior of the second terminal device is similar to that of the third terminal device.

[0178] Optionally, the first network device may also indicate the first resource or the first resource set to other network devices other than the second network device. After the other network devices learn of the first resource or the first resource set, they may also instruct the terminal devices they serve not to send uplink signals on the first resource or the first resource set, and may perform inter-base station CLI measurements on the first resource or the first resource set.

[0179] Based on this solution, since multiple adjacent network devices use the same resources for CLI measurement, there may be no uplink signal sent by the terminal device to the network device on the measurement resource (such as the first resource), thereby reducing the impact on the CLI measurement between base stations and improving the accuracy of the CLI measurement.

[0180] In the measurement resource configuration method provided in the embodiment of the present application, the first resource (i.e., the CLI measurement resource) may be a time domain periodic resource, so that the network device can flexibly configure the period, time unit, and sub-time unit of the first resource, thereby improving the CLI measurement performance. Alternatively, the first resource may be located in the time domain position of the PUSCH within a time unit, so that the network device can flexibly configure the first resource in the time domain position of the PUSCH, avoiding duplication of the first resource with the DMRS and / or UCI, thereby improving the CLI measurement performance. Alternatively, the first resource may be located in the time domain position corresponding to each frequency hop within the PUSCH, so that there is a CLI measurement resource in the time domain position corresponding to each frequency hop, so that CLI measurement can be performed before and after each frequency hop, thereby improving the CLI measurement performance.

[0181] Based on the above scheme, since the network device can know the time-frequency resource position of UCI, when configuring CLI measurement resources, the network device can try to make the CLI measurement resources not overlap with the time domain position of UCI. In addition, multiple OFDM symbols can be configured as CLI measurement resources in one time slot, such as configuring CLI measurement resources on OFDM symbols corresponding to the time domain positions of PDCCH and PDSCH, so as to achieve the measurement of CLI between base stations caused by PDCCH and PDSCH in the same time slot. Furthermore, the position of CLI measurement resources can be flexibly adjusted according to the position of PDCCH, so that the network device can measure the CLI between base stations caused by PDCCH. In addition, CLI measurement resources can be configured in the time domain position corresponding to each frequency hopping of PUSCH, so that the network device can perform CLI measurement before and after each frequency hopping, and can flexibly support PUSCH frequency hopping, thereby improving the measurement performance in the PUSCH frequency hopping scenario.

[0182] The above is a description of the overall process of the configuration method of the measurement resource provided in the embodiment of the present application. The following is a detailed introduction to the first resource and the first information.

[0183] In a possible implementation, when the first resource is a time domain periodic resource, the first information indicates at least one of the following: a period (or called a repetition offset) of the first resource, an offset (or called a repetition offset), or a sub-time unit where the first resource is located. The offset is used to indicate the time unit where the first resource is located.

[0184] Exemplarily, the value of the period T of the first resource can be one of {1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320, 640}, and correspondingly, the value of the offset offset can be offset = 0, 1, ..., T-1. Among them, the units of period and offset can be time units. Offset equal to x can be understood as: the time unit where the first resource is located is the x+1th time unit in a period of the first resource, or the time unit where the first resource is located is the x+1th time unit in T time units. For example, taking T equal to 4 and offset equal to 0 as an example, the time unit where the first resource is located can be time unit 0, time unit 4, time unit 8, time unit 12, etc.

[0185] In the case where the first information indicates the sub-time unit where the first resource is located:

[0186] As a possible implementation, the first information may include a first bitmap. The first bitmap includes X bits, and the X bits correspond one-to-one to the X sub-time units in the time unit where the first resource is located. X is the total number of sub-time units included in the time unit where the first resource is located. Among the X bits, the sub-time unit corresponding to the bit with the first value is the sub-time unit where the first resource is located, and the sub-time unit corresponding to the bit with the second value is not the sub-time unit where the first resource is located.

[0187] For example, the first value may be "1", and correspondingly, the second value may be "0". Alternatively, the first value may be "0", and correspondingly, the second value may be "1".

[0188] Exemplarily, taking the time unit as a time slot, the sub-time unit as an OFDM symbol, X equals 14, and the first value equals "1" as an example, when the first bitmap is {0,0,1,1,1,1,1,1,1,1,1,1,0,0}, it indicates that the OFDM symbols where the first resource is located are the middle 10 OFDM symbols in the time slot. If the indexes of the 14 OFDM symbols in the time slot are 0-13, the first resource is the OFDM symbol indexed 2-11 in the time slot.

[0189] As another possible implementation, the first information may include a second bit map. The second bit map includes Y bits, and the Y bits correspond one-to-one to the Y sub-time units in the time unit where the first resource is located. The Y sub-time units do not include the sub-time units used to carry DMRS. That is, the Y bits in the second bit map correspond one-to-one to the OFDM symbols excluding the symbols where the DMRS is located. Among the Y bits, the sub-time unit corresponding to the bit with the first numerical value is the sub-time unit where the first resource is located, and Y is a positive integer, and Y is less than or equal to X. The first numerical value can refer to the aforementioned related instructions and will not be repeated here.

[0190] Exemplarily, taking the time unit as a time slot, the sub-time unit as an OFDM symbol, X equals 14, the first value equals "1", and the indexes of the 14 OFDM symbols in the time slot are 0-13 as an example, assuming that the OFDM symbols with indexes 2 and 3 are used to carry DMRS, then Y equals 12, and the first two bits in the bitmap correspond to the OFDM symbols with indexes 0 and 1, respectively, and the last 10 bits correspond to the OFDM symbols with indexes 4-13, respectively. When the second bitmap is {0,0,1,1,1,1,1,1,1,1,0,0}, it indicates that the first resource is the OFDM symbol with indexes 4-11 in the time slot.

[0191] In a possible implementation manner, when the first resource is located within the first time domain, the PUSCH in the embodiment of the present application may have the following four situations:

[0192] Case 1: No PUSCH repetition.

[0193] In this case 1, the PUSCH is usually located in a time unit, that is, the time domain resource where the PUSCH is located is located in a time unit, and the PUSCH in the time unit can be understood as a PUSCH. At this time, the first time domain range is the time domain position of the PUSCH in a time unit, which can also be understood as: the first time domain range is the time domain position of the PUSCH.

[0194] For example, Fig.10 As shown in (a) in FIG. 1 , taking the time unit as a time slot and the sub-time unit as an OFDM symbol as an example, assuming that PUSCH#1 is transmitted in time slot 1, occupying OFDM symbols 1-13 in time slot 1, and another PUSCH#2 is transmitted in time slot 2, occupying OFDM symbols 1-13 in time slot 2. Then, for PUSCH#1, the first time domain range is symbols 1-13 in time slot 1. For PUSCH#2, the first time domain range is symbols 1-13 in time slot 2.

[0195] Case 2: PUSCH repetition type A:

[0196] In PUSCH repetition type A, PUSCH is repeated K times and only once in one time unit. That is, PUSCH is repeated K times in K time units, and the time domain position of PUSCH in each time unit is the same. K is a positive integer.

[0197] In a possible implementation manner, PUSCH repetition K times may be understood as PUSCH transmission K times in total. In this case, the first PUSCH transmission may also be understood as one PUSCH repetition.

[0198] In a possible implementation, K repetitions of a PUSCH may be understood as one PUSCH, and the time domain position of the PUSCH is located in K time units. At this time, the time domain position of the repetition in each time unit may be understood as a first time domain range. That is, the first time domain range is the time domain position of the PUSCH in one time unit, which may be understood as follows: the first time domain range is the time domain position repeated in each time unit in PUSCH repetition type A.

[0199] Optionally, the time domain position repeated within the time unit may also be understood as: the time domain position used for PUSCH repetition within the time unit, or the time domain position of PUSCH within the time unit, and the three may be interchangeable.

[0200] For example, Fig.10As shown in (b), the time unit is a time slot, the sub-time unit is an OFDM symbol, K is equal to 3, that is, PUSCH is repeated 3 times in 3 time slots. Assuming that OFDM symbols 2-9 in each time slot of time slots 1-3 are used to carry PUSCH, then it can be considered that the time domain position of the entire PUSCH includes OFDM symbols 2-9 in time slot 1, OFDM symbols 2-9 in time slot 2, and OFDM symbols 2-9 in time slot 3. In addition, OFDM symbols 2-9 in time slot 1, OFDM symbols 2-9 in time slot 2, and OFDM symbols 2-9 in time slot 3 are each a first time domain range. That is, it can be considered that there are 3 first time domain ranges in this scenario.

[0201] Case 3: PUSCH repetition type B:

[0202] In a possible implementation, in PUSCH repetition type B, PUSCH is repeated K times, and is repeated at least once in one time unit, for example, there may be 2 PUSCH repetitions in one time unit. That is, PUSCH is repeated K times in Q time units. K is a positive integer, and Q is a positive integer less than or equal to K.

[0203] Exemplarily, in PUSCH repetition type B, the network device may first indicate the nominal repetition (nominalrepetition) time domain position and the nominal number of repetitions, for example, indicating the starting OFDM symbol and the number of consecutive OFDM symbols and the nominal number of repetitions of the time domain position of the nominal repetition in the time slot. Among them, starting from the second nominal repetition (or called nominal PUSCH), the starting OFDM symbol of the next nominal repetition is the next OFDM symbol of the ending OFDM symbol of the previous nominal repetition. Taking the example that the starting OFDM symbol of the time domain position of the first nominal repetition in the time slot is symbol 0, the number of consecutive OFDM symbols is equal to 6, and the nominal number of repetitions is equal to 4, the time domain resources of the nominal repetition can be as follows: Fig.10 As shown in (c) in .

[0204] Subsequently, the terminal device may determine the actual repeated time domain position in the nominal repeated time domain position for PUSCH repetition transmission. The actual repeated time domain position may include the time domain position other than the invalid position in the nominal repeated time domain position. Exemplarily, the invalid position may include OFDM symbols configured as downlink symbols by high-level parameters and invalid symbols configured by high-level parameters. In addition, the boundaries of the invalid time domain position and the time unit boundary may serve as the boundaries of the actual PUSCH repetition.

[0205] For example, Fig.10As shown in (c), OFDM symbol 2 and OFDM symbol 5 in time slot 1, and OFDM symbol 5 in time slot 2 are configured as downlink symbols, and OFDM symbol 6 and OFDM symbol 7 in time slot 1, and OFDM symbol 6 and OFDM symbol 7 in time slot 2 are configured as invalid symbols. Based on this, Fig.10 In the example shown in (c) there are 7 actual PUSCH repetitions.

[0206] In a possible implementation, the time domain position of the actual repetition in each time unit can be understood as a first time domain range. That is, the first time domain range is the time domain position of the PUSCH in a time unit, which can be understood as: the first time domain range is the time domain position of the actual repetition in each time unit in the PUSCH repetition type B.

[0207] Optionally, the time domain position actually repeated within the time unit can also be understood as: the time domain position actually used for PUSCH repetition within the time unit, or, the time domain position actually repeated by PUSCH within the time unit, or, the actual time domain position of PUSCH within the time unit, or, the time domain position actually occupied by PUSCH within the time unit, and the five can be replaced with each other.

[0208] For example, Fig.10 As shown in (c), it can be considered that there are 7 first time domain ranges in this scenario, and the 7 first time domain ranges are the time domain positions of 7 actual PUSCH repetitions. For example, the first first time domain range is the time domain position of the first actual PUSCH repetition, that is, OFDM symbol 0 and OFDM symbol 1 in slot 1, and so on.

[0209] Case 4: Transport block (TB) spanning multiple time units.

[0210] Exemplarily, when the time unit is a time slot, this situation four can be understood as a transport block over multi-slot (TBoMS).

[0211] In the TB scenario across multiple time units, multiple time units are used to transmit a larger TB. A portion of the TB is transmitted on each time unit. At this time, the transmission of the entire TB can be regarded as a PUSCH. The time domain position of the PUSCH occupies multiple time units, and the time domain position of the PUSCH in each time unit can be understood as a first time domain range. That is, the first time domain range is the time domain position of the PUSCH in a time unit, which can be understood as: the first time domain range is the time domain position of the TB across multiple time units in each time unit.

[0212] For example, Fig.10 As shown in (d) in FIG. 1 , taking the time unit as a time slot, the sub-time unit as an OFDM symbol, and the TB being transmitted in two time units as an example, assuming that OFDM symbols 0-13 in each time slot of time slots 1-2 are used to carry TB, then it can be considered that the time domain position of the entire PUSCH includes all OFDM symbols in time slots 1 and 2. In addition, OFDM symbols 0-13 in time slot 1 and OFDM symbols 0-13 in time slot 2 are each a first time domain range. That is, it can be considered that there are two first time domain ranges in this scenario.

[0213] As a possible implementation, frequency hopping within the PUSCH can be understood as frequency hopping of the PUSCH within a time unit. One frequency domain position of the PUSCH within a time unit can be understood as one frequency hopping. For example, it can be considered Figure 7 In the example shown, there are two frequency hops, referred to as the first hop and the second hop.

[0214] Exemplarily, taking the time unit as a time slot, that is, frequency hopping within a time slot as an example, the frequency hopping pattern of the frequency hopping within the time slot may satisfy the following relationship:

[0215]

[0216] Here, i=0 and i=1 refer to the first hop and the second hop respectively. start Refers to the starting resource block (RB) of the PUSCH within the uplink bandwidth. The uplink bandwidth can be, for example, the uplink bandwidth part (BWP) or the uplink carrier. RB offset Refers to the frequency hopping interval between two frequency hopping, RB offset The unit is RB. The number of symbols in the first hop is The number of symbols in the second hop is The number of symbols occupied by PUSCH in a time slot.

[0217] As a possible implementation, the time domain position corresponding to each frequency hopping in the PUSCH can also be understood as: the time domain position corresponding to each frequency hopping of the PUSCH in a time unit, and / or, the time domain position corresponding to each frequency domain position of the PUSCH in a time unit. The frequency hopping of the PUSCH in a time unit can refer to the relevant description of the frequency hopping in the above time slot, which will not be repeated here.

[0218] Optionally, in the above situation, if there are two frequency hoppings in the PUSCH within a time unit, that is, there are two frequency domain positions of the PUSCH within the time unit, then the time domain position corresponding to each frequency domain position can be understood as a first time domain range.

[0219] For example, Fig.11 As shown in (a), taking the time unit as a time slot, the sub-time unit as an OFDM symbol, and a frequency hopping operation within the time slot as an example, assuming that PUSCH#1 is transmitted within time slot 1, occupying OFDM symbols 1-13 within time slot 1, and the frequency domain position of PUSCH in OFDM symbols 1-7 is frequency domain position 1, and the frequency domain position of PUSCH in OFDM symbols 8-13 is frequency domain position 2, then OFDM symbols 1-7 can be understood as a first time domain range, and OFDM symbols 8-13 can be understood as another first time domain range.

[0220] Optionally, in the above situation 2, if there are two frequency hops in the PUSCH in each time in PUSCH repetition type A, that is, there are two frequency domain positions in the PUSCH in each time unit, then the time domain position corresponding to each frequency domain position in each time unit can be understood as a first time domain range.

[0221] For example, Fig.11 As shown in (b), taking the time unit as a time slot, the sub-time unit as an OFDM symbol, and K equal to 3 as an example, assuming that OFDM symbols 2-9 in each time slot in time slots 1-3 are used to carry PUSCH, and the frequency domain position of PUSCH in OFDM symbols 2-5 in each time slot is frequency domain position 1, and the frequency domain position of PUSCH in OFDM symbols 6-9 is frequency domain position 2, then OFDM symbols 2-5 in each time slot can be understood as a first time domain range, and OFDM symbols 6-9 in each time slot can be understood as another first time domain range, that is, it can be considered that there are 6 first time domain ranges in this scenario.

[0222] Optionally, in the above situation 4, if the TB across multiple time units has two frequency hops in each time unit, then the time domain position corresponding to each frequency hop in each time unit can be understood as a first time domain range, and the above Fig.11 The example described in (b) will not be repeated here.

[0223] In the case where the first resource is within the first time domain range, the first information may indicate N sub-time units within the first time domain range, where the N sub-time units are the sub-time units where the first resource is located, and N is a positive integer. For example, N is equal to 1, that is, there is one sub-time unit in the first time domain range for CLI measurement.

[0224] Exemplarily, the first information may include the index of the N sub-time units. The index of the N sub-time units may be the index of the sub-time unit within the time unit, or may be the index of the sub-time unit within the first time domain. Taking the time unit as a time slot, the sub-time unit as an OFDM symbol, and a time slot including 14 OFDM symbols (indexed 0-13) as an example:

[0225] In the case where the first time domain range is the time domain position of the PUSCH within a time unit, and the time domain position of the PUSCH includes OFDM symbols indexed 1-13 in the time slot, if the index of the N sub-time units is the index of the sub-time unit in the time unit, then the index of the N sub-time units may be located within 0-13. If the index of the N sub-time units is the index of the sub-time unit in the first time domain range, then the first time domain range includes 13 sub-time units, and the index of the N sub-time units may be located within 0-12.

[0226] In the case where the first time domain range is the time domain position corresponding to each frequency hop within the PUSCH, assuming that when the first terminal device sends PUSCH, the time domain position of the first hop within a time slot is OFDM symbols 0-6, and the time domain position of the second hop is OFDM symbols 7-13, if the index of the N sub-time units is the index of the sub-time unit in the time unit, then the index of the N sub-time units corresponding to the first hop can be located within 0-6, and the index of the N sub-time units corresponding to the second hop can be located within 7-13.

[0227] If the indexes of the N sub-time units are indexes of the sub-time units within the first time domain, the indexes of the N sub-time units corresponding to the first hop and the second hop may both be within 0-6.

[0228] In the case where the first time domain range is the time domain position corresponding to each frequency hopping in the PUSCH, the positions of the N sub-time units corresponding to each frequency hopping in the first time domain range may be the same. At this time, the first information may only indicate the N sub-time units. For example, taking N equal to 1 as an example, the first information may indicate that the nth sub-time unit in each first time domain range is the sub-time unit where the first resource is located. The first information may include an index n.

[0229] Alternatively, the positions of the N sub-time units corresponding to each frequency hop within the first time domain range may be different, in which case the first information may indicate the N sub-time units within each first time domain range respectively. For example, taking N equal to 1 and two frequency hops within a time unit as an example, the first information may indicate that the nth sub-time unit within the first time domain range corresponding to the first hop is the sub-time unit where the first resource is located, and indicates that the mth sub-time unit within the first time domain range corresponding to the second hop is the sub-time unit where the first resource is located. Where n and m are different, the first information may include index n and index m.

[0230] Optionally, the first information may be carried in RRC signaling, in which case the N sub-time units may be considered to be semi-statically configured. Alternatively, the first information may be carried in DCI, in which case the N sub-time units may be considered to be dynamically configured. In the case where the first information is carried in DCI, before the DCI, the first network device may configure a set of candidate sub-time units, and the DCI may indicate N sub-time units from the candidate sub-time units.

[0231] When the first resource is located within the first time domain range, the time domain position of the first resource may satisfy at least one of the following conditions:

[0232] 1) The time domain position of the first resource is the first sub-time unit in the first time domain range that is not used to carry DMRS.

[0233] For example, Fig.12 As shown in (a), taking the time domain position of PUSCH in a time slot including OFDM symbols 1-13, that is, the first time domain range includes OFDM symbols 1-13 as an example, assuming that OFDM symbol 3 is used to carry DMRS, then the first sub-time unit in the first time domain range that is not used to carry DMRS is OFDM symbol 1.

[0234] 2) The time domain position of the first resource is the first sub-time unit in the first time domain range that is not used to carry UCI. Please refer to the relevant description in condition 1), which will not be repeated here.

[0235] 3) The time domain position of the first resource is the first sub-time unit in the first time domain range that is not used to carry DMRS and is not used to carry UCI.

[0236] For example, Fig.12As shown in (b), taking the time domain position of PUSCH in a time slot including OFDM symbols 1-13, that is, the first time domain range includes OFDM symbols 1-13 as an example, assuming that OFDM symbol 3 is used to carry DMRS and OFDM symbol 4 is used to carry UCI, then the first sub-time unit in the first time domain range that is not used to carry DMRS and is not used to carry UCI is OFDM symbol 1. Or, Fig.12 As shown in (c), assuming that OFDM symbol 1 is used to carry DMRS and OFDM symbol 2 is used to carry UCI, then the first sub-time unit in the first time domain range that is not used to carry DMRS and is not used to carry UCI is OFDM symbol 3.

[0237] 4) The time domain position of the first resource is the first sub-time unit not used to carry DMRS after the first sub-time unit used to carry DMRS in the first time domain range.

[0238] For example, Fig.13 As shown, taking the case where the time domain position of the PUSCH in a time slot includes OFDM symbols 1-13, that is, the first time domain range includes OFDM symbols 1-13, as an example, assuming that OFDM symbol 3 and OFDM symbol 4 are used to carry DMRS, then the first sub-time unit used to carry DMRS is OFDM symbol 3. The first sub-time unit after OFDM symbol 3 that is not used to carry DMRS is OFDM symbol 5. That is, the first sub-time unit that is not used to carry DMRS after the first sub-time unit used to carry DMRS in the first time domain range is OFDM symbol 5.

[0239] 5) The time domain position of the first resource is the first sub-time unit not used to carry UCI after the first sub-time unit used to carry UCI in the first time domain range. Please refer to the relevant description in condition 4) and will not be repeated here.

[0240] 6) The time domain position of the first resource is the first sub-time unit that is not used to carry DMRS and not used to carry UCI after the first sub-time unit used to carry DMRS in the first time domain range.

[0241] For example, Fig.14 As shown, taking the time domain position of PUSCH in a time slot including OFDM symbols 1-13, that is, the first time domain range includes OFDM symbols 1-13 as an example, assuming that OFDM symbol 3 is used to carry DMRS and OFDM symbol 4 is used to carry UCI, then the first sub-time unit used to carry DMRS is OFDM symbol 3, and the first sub-time unit after OFDM symbol 3 that is not used to carry DMRS and is not used to carry UCI is OFDM symbol 5.

[0242] 7) The time domain position of the first resource is the first sub-time unit not used to carry DMRS and different from the sub-time unit carrying UCI in the first time domain range after the first sub-time unit used to carry UCI. Please refer to the relevant description of condition 6) and will not be repeated here.

[0243] Optionally, when the time domain position of the first resource satisfies at least one of the above conditions, the protocol may define the above 7 conditions or the first network device may pre-configure the above 7 conditions to the first terminal device. In this scenario, the first information may indicate at least one of the above 7 conditions, for example, the first information includes an index of at least one condition. Alternatively, the protocol may define one of the above 7 conditions. In this case, the first network device and the first terminal device assume that the condition satisfied by the time domain position of the first resource is the condition defined by the protocol. The first information may indicate the frequency domain position of the first resource, but does not indicate the time domain position of the first resource.

[0244] Optionally, UCI can meet at least one of the following:

[0245] UCI is hybrid automatic repeat request-acknowledgement (HARQ-ACK) information;

[0246] UCI includes HARQ-ACK information and channel state information-reference signal (CSI-RS) part 1;

[0247] UCI includes HARQ-ACK information, CSI-RS part 1, and the joint coding of HARQ-ACK and configured grant (CG) UCI ​​(i.e., CG-UCI);

[0248] UCI includes HARQ-ACK information, CSI-RS part 1, CSI-RS part 2, and joint coding of HARQ-ACK and CG-UCI;

[0249] UCI is the joint coding of HARQ-ACK and CG-UCI;

[0250] UCI includes HARQ-ACK information and joint coding of HARQ-ACK and CG-UCI.

[0251] Optional, above Figure 12 to Figure 14 Taking the first time domain range as the time domain position of the PUSCH within a time unit as an example, when the first time domain range is the time domain position corresponding to each frequency hopping of the PUSCH, Figure 12 to Figure 14 The time domain position of PUSCH in is replaced by the time domain position corresponding to one frequency hopping for easy understanding, which will not be repeated here.

[0252] In a possible implementation, the first resource that is periodically repeated in the time domain (i.e., the first type of measurement resource) and the first resource located within the first time domain (recorded as the second type of measurement resource) may exist at the same time, or one of the two types of measurement resources may exist within a certain period of time. That is, the first network device may configure the first type of measurement resource and the second type of measurement resource at the same time, or only configure the first type of measurement resource or only configure the second type of measurement resource within a certain period of time.

[0253] In a possible implementation, the time domain position of the first resource does not overlap with the time domain position of the fourth resource. The fourth resource is used to carry DMRS, and / or the fourth resource is used to carry UCI. That is, the time domain position of the first resource does not overlap with the time domain position of DMRS and / or UCI.

[0254] Based on this possible implementation, when the time domain position of the first resource does not overlap with the time domain position of DMRS and / or UCI, the CLI measurement will not affect the DMRS and / or UCI, thereby not affecting the demodulation of the uplink data and / or the transmission of UCI, thereby improving the transmission performance of the uplink data and / or UCI.

[0255] In a possible implementation manner, if the time domain position of the CLI measurement resource overlaps with the fourth resource, it can be processed according to the following criteria:

[0256] 1) Abandon the CLI measurement resources, or consider the CLI measurement resources to be an empty set. In this scenario, it can be considered that the transmission of DMRS and / or UCI is prioritized, and the CLI measurement is abandoned.

[0257] 2) Discard the portion of the CLI measurement resource that overlaps with the fourth resource.

[0258] As a possible implementation, the first network device can indicate a CLI measurement resource to the first terminal device, but the measurement resource may contain a portion that overlaps with a fourth resource. In this case, the first terminal device and the first network device can discard the portion of the original CLI measurement resource that overlaps with the fourth resource, and use the portion that does not overlap with the fourth resource for CLI measurement.

[0259] That is, the first information indicating the first resource may include: the first information indicating the fifth resource, the fifth resource is used for CLI measurement, that is, the fifth resource is the original CLI measurement resource. There is a part of the fifth resource that overlaps with the fourth resource. At this time, the first resource includes the resources in the fifth resource that do not overlap with the fourth resource.

[0260] As a possible implementation, the first resource may also include M sub-time units after the fifth resource, where M is the number of sub-time units occupied by the fourth resource. That is, after discarding the portion of the original CLI measurement resource that overlaps with the fourth resource, a resource of a corresponding size may be added as a new CLI measurement resource.

[0261] For example, Fig.15 As shown, taking the time unit as a time slot and the sub-time unit as an OFDM symbol as an example, assuming that the OFDM symbol where the fifth resource is located includes OFDM symbols 1-6, but OFDM symbol 3 is used to carry DMRS and OFDM symbol 4 is used to carry UCI, then the first resource may first include OFDM symbols 1-2 and OFDM symbols 5-6. Further, two more OFDM symbols (such as OFDM symbols 7-8) may be added after OFDM symbol 6 as the first resource. That is, the first resource includes OFDM symbols 1-2 and OFDM symbols 5-8.

[0262] Based on the above criteria, it can be ensured that the resources actually used for CLI measurement do not overlap with the time domain position of DMRS and / or UCI, thereby avoiding the impact of CLI measurement on DMRS and / or UCI, reducing the impact of CLI measurement on uplink data demodulation and / or UCI transmission, and improving the transmission performance of uplink data and / or UCI.

[0263] The above describes the time domain position of the first resource, and the following describes the frequency domain position of the first resource. First, regarding the frequency domain bandwidth of the first resource:

[0264] In a first possible implementation manner, the first information may indicate a starting RB of the frequency domain bandwidth and the number of RBs included in the frequency domain bandwidth.

[0265] In a second possible implementation, the frequency domain bandwidth of the first resource is the same as the frequency domain bandwidth of the second resource, that is, the frequency domain bandwidth of the first resource is the same as the frequency domain bandwidth of the PUSCH, that is, the starting RB and the number of RBs included in the bandwidth of the two are the same.

[0266] In a third possible implementation, the frequency domain bandwidth of the first resource may be an uplink part bandwidth (bandwidth part, BWP), or an uplink carrier, or an uplink subband (such as an uplink subband in a SBFD scenario).

[0267] In the above second and third possible implementations, the first information may not indicate the frequency domain bandwidth of the first resource. The first network device and the first terminal device may default that the frequency domain bandwidth of the first resource is the same as the frequency domain bandwidth of the second resource, or default that the frequency domain bandwidth of the first resource is the bandwidth of the uplink BWP or the uplink carrier or the uplink subband.

[0268] The resource elements (REs) occupied by the first resource in the frequency domain bandwidth may be distributed in a comb-tooth distribution. Exemplarily, the number of comb teeth may be 2. Of course, other comb-tooth numbers may also be used, such as 4, etc., which are not specifically limited in this application. The first resource has the same position in each RB, that is, the first resource occupies the same REs in each RB.

[0269] In a possible implementation, the first resource occupies P REs in one RB, and the index difference between any two adjacent REs in the P REs is Q / P, where Q is the total number of REs included in one RB, and P and Q are positive integers. Further, P is a divisor of Q.

[0270] For example, taking Q equal to 12 and P equal to 6 as an example, the first resource occupies 6 REs in one RB, and the index difference between any two adjacent REs is 2. Taking Q equal to 12 and P equal to 3 as an example, the first resource occupies 3 REs in one RB, and the index difference between any two adjacent REs is 4.

[0271] As a first possible implementation, when the REs occupied by the first resource are in a 2-comb distribution (for example, Q is equal to 12 and P is equal to 6), the index of each RE occupied by the first resource can be indicated in the following two ways:

[0272] Mode 1: The first information includes a first field. When the value of the first field is a third numerical value, the frequency domain position of the first resource in an RB is an RE with an even index, that is, the first resource occupies an RE with an even index in an RB. When the value of the first field is a fourth numerical value, the frequency domain position of the first resource in an RB is an RE with an odd index, that is, the first resource occupies an RE with an odd index in an RB.

[0273] Mode 2: The index of REs occupied by the first resource in one RB satisfies: 2n+k, where k=0 or 1, and n=0, 1, ..., Q / 2-1.

[0274] In this manner, the first information may indicate the value of k, and the index of the RE occupied by the first resource is determined by the value of k. When k=0, the first resource occupies the RE with an even index in one RB; when k=1, the first resource occupies the RE with an odd index in one RB.

[0275] For example, Fig.16 As shown in FIG. 1 , taking the time unit as a time slot and the sub-time unit as an OFDM symbol as an example, the black filled part in the figure can be understood as the time-frequency position of the first resource. Fig.16In the example, the first resource is located at OFDM symbol 4 and OFDM symbol 9 in the time domain, and is located at REs with even indexes within the RB in the frequency domain.

[0276] As a second possible implementation, the index i of the RE occupied by the first resource in the RB satisfies: i=nL+k.

[0277] Where L is a divisor of Q, Q is the number of REs included in RB; k is one of 0, 1, ..., L-1, L is an integer greater than 1.

[0278] For example, taking L=4, k=2 as an example, the first resource occupies REs with indexes 2, 6, and 10 in the RB. Fig.17 As shown in FIG. 1 , taking the time unit as a time slot and the sub-time unit as an OFDM symbol as an example, the black filled part in the figure can be understood as the time-frequency position of the first resource. Fig.17 In the example, the first resource is located at OFDM symbol 4 and OFDM symbol 9 in the time domain, and is located at REs indexed as 2, 6, and 10 in the RB in the frequency domain.

[0279] It can be understood that, regarding the REs occupied by the first resource in the RB, the first possible implementation can be understood as a special case of the second implementation. For example, when L in the second possible implementation is equal to 2, the second possible implementation is the same as the first possible implementation.

[0280] Optionally, when the time domain positions of the first resource and the second resource overlap and the REs occupied by the first resource are comb-tooth distributed, on the OFDM symbol where the first resource and the second resource overlap, the REs not occupied by the first resource can be used to send the first signal.

[0281] For example, Fig.16 or Fig.17 As shown, assuming that the first resource and the second resource overlap on OFDM symbol 4 and OFDM symbol 9, then Fig.16 In the scenario shown, REs with odd indexes on OFDM symbol 4 and OFDM symbol 9 can be used to send the first signal. Fig.17 In the scenario shown, REs indexed as 0, 1, 3, 4, 5, 7, 8, 9, and 11 on OFDM symbol 4 and OFDM symbol 9 may be used to send a first signal.

[0282] Optionally, in this scenario, the transmit power spectral density of the first signal on the OFDM symbol where the second resource overlaps with the first resource is Q / (QQ / L) times the transmit power spectral density of the first signal on the OFDM symbol where the two do not overlap. For example, taking Q equal to 12 and L equal to 2 as an example, assuming that Fig.16 or Fig.17In the scenario shown, the second resource also includes OFDM symbol 5, so the transmit power spectral density of the first signal on OFDM symbol 4 and OFDM symbol 9 is twice the transmit power spectral density of the first signal on OFDM symbol 5.

[0283] Optionally, the transmit power spectrum density of the first signal on the OFDM symbol where the second resource does not overlap with the first resource may be indicated by the first network device. For example, the first network device may indicate the transmit power spectrum density in the second information.

[0284] It should be noted that in the embodiment of the present application, the time domain position allocation and the frequency domain position allocation of the first resource can be implemented independently, that is, there is no mutual dependence between the two, and the time domain position allocation is not affected by the frequency domain position allocation, and the frequency domain position allocation is not affected by the time domain position allocation. That is, the time domain position of the first resource can be allocated according to the above scheme, and the frequency domain position of the first resource can be allocated according to other schemes; or, the frequency domain position of the first resource can be allocated according to the above scheme, and the time domain position of the first resource can be allocated according to other schemes. Of course, the time domain position and frequency domain position of the first resource can also be allocated according to the above scheme.

[0285] It is understandable that in the above embodiments, the methods and / or steps implemented by the network device may also be implemented by components (such as processors, chips, chip systems, circuits, logic modules, or software) that can be used in the network device; the methods and / or steps implemented by the terminal device may also be implemented by components (such as processors, chips, chip systems, circuits, logic modules, or software) that can be used in the terminal device.
