A method and device for configuring measurement resources

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on August 10, 2023, with application number 202311014175.3 and application name “A method and device for configuring measurement resources”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and in particular to a method and apparatus for configuring measurement resources. Background Art

[0003] To improve uplink coverage and reduce uplink latency in mobile communication systems, subband full duplex (SBFD) can be used. In SBFD, the frequency band for downlink symbols is divided into uplink subbands and downlink subbands, allowing uplink transmission on the uplink subband of downlink symbols.

[0004] In addition, mobile communication systems also support dynamic / flexible time division duplex (TDD), which allows different cells to use different uplink and downlink time slot ratios and supports dynamic changes in the uplink and downlink time slot ratios.

[0005] However, SBFD and dynamic / flexible TDD introduce cross-link interference (CLI) between base stations, requiring base stations to perform CLI measurements. Therefore, how to configure CLI measurement resources is an urgent issue to be resolved.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide a method and apparatus for configuring measurement resources, which can flexibly configure the time domain location of CLI measurement resources, thereby improving CLI measurement performance.

[0008] In the 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, chip, or chip system of the first network device, or by a logic module or software that can implement all or part of the functions of the first network device. The method comprises: sending first information to a first terminal device, wherein the first information 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.

[0009] 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 in which it is located, and the 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, avoiding duplication of the first resource with the DMRS and / or UCI, and 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.

[0010] In one possible design, the method further includes: sending second information to the first terminal device, the second information indicating a second resource, where the second resource is a resource where the PUSCH is located. Receiving a first signal from the first terminal device on a third resource, where the third resource is a resource in the second resource that does not overlap with the first resource.

[0011] On 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, chip, or chip system of the first terminal device, or 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. 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.

[0012] 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 in which it is located, and the 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 within 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.

[0013] 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 the 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.

[0014] 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.

[0015] 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.

[0016] In combination with the first aspect or the second aspect, in one 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.

[0017] In combination with the first aspect or the second aspect, in one 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 the transport block TB across multiple time units in each time unit.

[0018] Based on this possible design, CLI measurements in various PUSCH transmission scenarios can be flexibly supported. When PUSCH transmission involves multiple time units, CLI measurement resources can be present in each time unit or each actually repeated time domain position, thereby enabling the network device to perform CLI measurements in each time unit or each actually repeated time domain position, thereby improving measurement accuracy.

[0019] In combination with the first aspect or the second aspect, in one possible design, the first information indicates N sub-time units within the 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.

[0020] 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.

[0021] In combination with the first aspect or the second aspect, in one possible design, the time domain location of the first resource satisfies at least one of the following:

[0022] The first sub-time unit within the first time domain range that is not used to carry a non-demodulation reference signal DMRS;

[0023] The first sub-time unit in the first time domain range that is not used to carry uplink control information UCI;

[0024] 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;

[0025] 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;

[0026] 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;

[0027] 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;

[0028] The first sub-time unit that is not used to carry DMRS and is not used to carry UCI after the first sub-time unit used to carry UCI in the first time domain range.

[0029] In combination with the first aspect or the second aspect, in one 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.

[0030] 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.

[0031] In combination with the first aspect or the second aspect, in one 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.

[0032] 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.

[0033] In combination with the first aspect or the second aspect, in one possible design, the UCI satisfies at least one of the following:

[0034] UCI is the hybrid automatic repeat request confirmation HARQ-ACK information;

[0035] UCI includes HARQ-ACK information and channel state information reference signal CSI-RS part 1;

[0036] UCI includes HARQ-ACK information, CSI-RS part 1, and the joint coding of HARQ-ACK and configuration grant UCI;

[0037] 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;

[0038] UCI is the joint coding of HARQ-ACK and CG-UCI;

[0039] UCI includes HARQ-ACK information and joint coding of HARQ-ACK and CG-UCI.

[0040] 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.

[0041] In combination with the first aspect or the second aspect, in a possible design, the index i of the resource element RE occupied by the first resource in the resource block RB satisfies: i=nL+k

[0042] 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.

[0043] Based on the above two possible designs, the REs occupied by the first resource can be distributed in a comb-teeth pattern, so that the REs not used for the first resource can be used to carry other signals, thereby improving resource utilization.

[0044] 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.

[0045] 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 for 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.

[0046] In a third aspect, a communication device is provided, comprising a unit or module configured to perform any of the methods described in the first or second aspects. The module or unit may be implemented in hardware, software, or by hardware executing a corresponding software implementation. The hardware or software may include one or more modules or units corresponding to the functions.

[0047] In some possible designs, the communication device may include a processing module and a transceiver module. The processing module may be configured to implement the processing functionality of any of the above aspects and any possible implementations thereof. The transceiver module may include a receiving module and a transmitting module, respectively configured to implement the receiving functionality and the transmitting functionality of any of the above aspects and any possible implementations thereof.

[0048] In some possible designs, the transceiver module may be composed of a transceiver circuit, a transceiver, a transceiver or a communication interface.

[0049] In a fourth aspect, a communication device is provided, comprising a processor configured to execute any of the methods described in the first or second aspects. There may be one or more processors. The communication device may further comprise a memory configured to store computer instructions that, when executed by the processor, cause the communication device to execute any of the methods described in the first or second aspects. The memory may be coupled to the processor or may be independent of the processor. The communication device may further comprise a communication interface configured to communicate with modules external to the communication device.

[0050] The communication device in the third and fourth aspects may be the first network device in the first aspect, or a device included in the first network device, such as a chip or a chip system; alternatively, the communication device may be the first terminal device in the second aspect, or a device included in the first terminal device, such as a chip or a chip system. When the communication device is a chip, the sending action / function of the communication device may be understood as outputting information, and the receiving action / function of the communication device may be understood as inputting information.

[0051] In a fifth aspect, a computer-readable storage medium is provided, which stores a computer program or instruction. When the computer program or instruction is run on a communication device, the communication device can execute any method described in the first aspect or the second aspect.

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

[0084] In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction to the relevant technologies of the present application is first given as follows.

[0085] 1. Subband full duplex (SBFD):

[0086] Time division duplex (TDD) is widely used in fifth-generation (5G) mobile communication systems. TDD separates transmission and reception in the time domain, dividing time resources into uplink and downlink resources. Terminal devices transmit on uplink resources and receive on downlink resources.

[0087] For example, as shown in Figure 1, a possible TDD uplink and downlink time slot ratio is DDDSU. Wherein, 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 and is used for downlink transmission. Each symbol in the uplink time slot is an uplink symbol and is used for uplink transmission. Special time slots include at least flexible symbols, which can be used for both downlink transmission and uplink transmission.

[0088] In the commonly used TDD uplink and downlink time slot ratio, uplink time domain resources are usually limited, which leads to reduced TDD uplink coverage and increased latency. One possible uplink enhancement method is to use SBFD.

[0089] SBFD divides the frequency band of downlink symbols into at least one uplink subband and at least one downlink subband, allowing terminal devices to perform uplink transmissions on the uplink subband of downlink symbols. The subbands in SBFD may or may not overlap, and this application does not specifically limit this.

[0090] For example, as shown in FIG2 , in a certain time slot, sub-band 1 and sub-band 2 may be divided in the frequency domain, allowing downlink transmission on sub-band 1 and uplink transmission on sub-band 2 .

[0091] Currently, base stations support full-duplex (SBFD), meaning they can simultaneously receive on the uplink subband and transmit on the downlink subband in a timeslot. Terminals support half-duplex (HD) SBFD, meaning they can only transmit on the uplink subband or only receive on the downlink subband in a timeslot.

[0092] 2. Dynamic / Flexible TDD:

[0093] Dynamic / flexible TDD supports different uplink and downlink time slot ratios for different cells and supports dynamic changes in uplink and downlink time slot ratios. For example, as shown in Figure 3, 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.

[0094] 3. Cross link interference (CLI):

[0095] CLI can be understood as interference between communication links in opposite directions, such as interference from an uplink to a downlink, or vice versa.

[0096] In SBFD or dynamic TDD mechanisms, CLI between base stations is typically 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 this application refers to CLI between base stations or CLI between network devices.

[0097] For example, as shown in Figure 2, assuming that base station 1 transmits downlink signal 1 to terminal device 1 on subband 1, and base station 2 receives uplink signal 2 from terminal device 2 on subband 2, the interference caused by downlink signal 1 transmitted by base station 1 on uplink signal 2 received by base station 2 can be considered as inter-base station CLI. Furthermore, because the base stations support FD SBFD, the downlink signal transmitted by base station 2 on subband 1 also generates CLI for the signal received by base station 1 on subband 2.

[0098] Alternatively, as shown in Figure 3, assume that at the same time, cell 1 of base station 1 uses the uplink and downlink timeslot ratio of DDDSU, and cell 2 of base station 2 uses the uplink and downlink ratio of DSUUU. If base stations 1 and 2 are synchronized, then in timeslot 3, the downlink signal sent by base station 1 will generate a CLI for the uplink signal received by base station 2.

[0099] Due to the existence of CLI between base stations, it is necessary to measure and compensate for the CLI between base stations to suppress the impact of the CLI between base stations on uplink communication.

[0100] In a possible implementation, channel state information-interference measurement (CSI-IM) resources may be used to perform CLI measurement between base stations.

[0101] The CSI-IM resource is originally used for downlink interference measurement between cells. The CSI-IM resource supports two time-frequency patterns: pattern 0 and pattern 1. Each time-frequency pattern occupies four resource elements (REs), but the two patterns have different time-frequency locations. As shown in Figure 4 (a), in pattern 0, the CSI-IM resource occupies two consecutive symbols in the time domain; as shown in Figure 4 (b), in pattern 1, the CSI-IM resource occupies one symbol in the time domain.

[0102] 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.

[0103] However, if CSI-IM resources are directly used for CLI measurement between base stations, the following problems may occur:

[0104] 1) CSI-IM resources may conflict with the time-frequency resources multiplexed with uplink control information (UCI), resulting in reduced UCI multiplexing performance.

[0105] Exemplarily, the cause of this problem is that 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.

[0106] 2) It is impossible to measure the CLI between base stations caused by different downlink channels in the same time slot.

[0107] Typically, the inter-base 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 one symbol or two consecutive symbols in a time slot, and PDCCH and PDSCH are usually not located on one symbol or two consecutive symbols, it is impossible to measure the inter-base station CLI caused by PDCCH and PDSCH separately in the same time slot.

[0108] In another possible implementation, as shown in FIG5 , resources for inter-base station CLI measurement (hereinafter referred to as CLI measurement resources) may be located on the first symbol in a time slot (such as symbol 0 in FIG5 ), or may be located on the first symbol after the first demodulation reference signal (DMRS) of the PUSCH (such as symbol 4 in FIG5 ).

[0109] However, if the CLI measurement resource is located at the first symbol in a timeslot, inter-base station CLI caused by the PDCCH may not be measured. For example, the PDCCH can be located at any symbol in a timeslot. As shown in Figure 6, if the PDCCH is located at symbols 5 and 6 in a timeslot, and the CLI measurement resource is located at symbol 0 in the timeslot, then inter-base station CLI caused by the PDCCH cannot be measured due to the different time domain locations of the CLI measurement resource and the PDCCH.

[0110] In addition, for frequency hopping within a PUSCH timeslot, the frequency domain position of the PUSCH changes before and after the frequency hop, and the received inter-base station CLI also changes. Re-measurement of CLI is required after the frequency hop. If the CLI measurement resource is located only in the first symbol after the first DMRS of the PUSCH, inter-base station CLI cannot be measured after the frequency hop.

[0111] For example, as shown in FIG7 , the first DMRS of the PUSCH is located at symbol 3, and the first symbol after the first DMRS is symbol 4. Assuming that the frequency domain position of the PUSCH from symbols 0 to 6 is frequency domain position 1, and frequency hopping occurs after symbol 6, that is, the frequency domain position of the PUSCH from symbols 7 to 13 is frequency domain position 2, then the inter-base station CLI before frequency hopping can only be measured at symbol 4. Since there are no CLI measurement resources at other positions, the inter-base station CLI after frequency hopping cannot be measured.

[0112] 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, which has low flexibility. 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 measurement performance.

[0113] The technical solution provided in this application can be used in various communication systems, which may 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 hybrid networking of LTE and NR, 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.

[0114] 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 described here and will not be repeated below.

[0115] 8 , which shows 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.

[0116] Optionally, the communication system may further include a second network device and a second terminal device. Downlink transmission occurs 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.

[0117] Furthermore, the communication system may further 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 downlink transmission may occur between the third terminal device and the fourth terminal device is a terminal device served by the second network device, and uplink transmission may occur between the third terminal device and the fourth terminal device.

[0118] In a possible implementation scenario, downlink transmission between the second network device and the second terminal device interferes with the first network device receiving the 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.

[0119] It should be noted that Figure 8 is only a schematic diagram. The communication system may also include other devices, such as wireless relay devices, wireless backhaul devices, core network devices / network elements, etc., which are not shown in Figure 8. The number of network devices and terminal devices in Figure 8 is only an example. The communication system may include more or fewer network devices or terminal devices than shown in Figure 8.

Exemplarily, the base stations in the embodiments of the present application may include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, access points, etc., and the embodiments of the present application do not specifically limit this.

[0123] In some implementation scenarios, the network device may also be a module or unit that can implement some or all of the functions of a base station. For example, the network device may be a centralized unit (CU), a distributed unit (DU), a CU and a DU, a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU).

[0127] The following will describe the configuration method of measurement resources provided in an embodiment of the present application in detail with reference to the accompanying drawings, taking the interaction between the network device and the terminal device shown in FIG8 as an example.

[0128] It is understandable that in the embodiment of the present application, the network device or terminal device can 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 can also perform other steps or operations or variations of each step or operation. In addition, each step or operation can be performed in a different order presented in the embodiment of the present application, and it is possible not to perform all the steps or operations in the embodiment of the present application. For example, when the first network device is a CU, a DU, or a RU, it may only be possible to perform some of the steps or operations performed by the first network device described in the embodiment of the present application, and other operations are performed by at least one other network device.

[0129] 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. Other names may be used in specific implementations, and the embodiments of the present application do not specifically limit this.

[0130] FIG9 is a flow chart of a method for configuring measurement resources provided in an embodiment of the present application. The method for configuring measurement resources includes the following steps:

[0131] 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.

[0132] The first information indicates a first resource, and the first resource is used for CLI measurement. Specifically, the first resource is used for inter-base station CLI (or inter-network device CLI) measurement.

[0133] In one possible implementation, the first resource is a time-domain periodic resource. That is, the first resource is periodically repeated in the time domain. For example, the repetition period of the first resource may be in units of time slots, symbols, etc., or in units of duration (e.g., milliseconds (ms)).

[0134] In another possible implementation, the first resource is located within a first time domain range. The first time domain range is a time domain position of a PUSCH within a time unit, or the first time domain range is a time domain position corresponding to each frequency hopping within the PUSCH.

[0135] 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.

[0136] 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.

[0137] Since the first resource is used for inter-base station CLI measurement, 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 will send an uplink signal on the first resource. If the first terminal device sends an uplink signal on the first resource, then when the inter-base station CLI measurement is performed 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 the inter-base station CLI measurement.

[0138] In a possible implementation, the first information may be carried in radio resource control (RRC) signaling. In this scenario, it can be considered that the first resource is semi-statically configured through RRC signaling.

[0139] 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.

[0140] 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 take effect 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.

[0141] 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.

[0142] 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. As a result, the terminal devices may not send uplink signals on the first resource or the resources in the first resource set, thereby reducing the impact on CLI measurement.

[0143] S902: The first network device measures a CLI on a first resource.

[0144] In a possible implementation, 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.

[0145] As a possible implementation, the second network device can send a downlink signal (referred to as a second signal) to the second terminal device. The first network device can measure, on the first resource, the signal quality, signal strength, or covariance matrix of the second signal sent by the second network device to the second terminal device. The signal quality, signal strength, or covariance matrix can be understood as the inter-base station CLI caused by the second network device to the first network device.

[0146] In a possible implementation, the method may further include the following steps:

[0147] 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.

[0148] The second information indicates a 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 can be carried in the DCI or RRC signaling that schedules the PUSCH.

[0149] In a possible implementation manner, the second resource and the first resource overlap in the time domain and / or frequency domain.

[0150] It should be noted that there is no temporal order for step S903 and step S901. Step S903 may be performed first, followed by step S901; or step S901 may be performed first, followed by 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 impose any specific limitations on this.

[0151] 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 this application.

[0152] S904: The first terminal device sends a first signal to the first network device via the third resource. Correspondingly, the first network device receives the first signal from the first terminal device via the third resource.

[0153] 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.

[0154] In one possible implementation, before step S904, the first terminal device may determine a third resource based on the first information and the second information. Exemplarily, the third resource is the difference between the second resource and the first resource, i.e., the third resource is a resource within the second resource that does not overlap with the first resource. Furthermore, before step S904, the first network device also needs to determine the third resource in the same manner as the first terminal device, and will not be further described here.

[0155] In a possible implementation, before step S904, the first terminal device may generate the first signal in the following two ways:

[0156] Method 1: Generate the first signal by rate matching. Exemplarily, in this method, the first terminal device may perform the following steps:

[0157] 1) Determine the total number of coded bits G that can be used for TB transmission according to the size of the third resource.

[0158] Exemplarily, the total number of coded bits may be determined based on the total number of REs included in the third resource, the modulation order of the first signal, and the number of layers (or transmission layers or streams) of the first signal. For example, the total number of coded bits satisfies the following relationship: G = N RE,3 ×Q m ×N L

[0159] Among them, N RE,3 Indicates the total number of REs included in the third resource. m Indicates 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) Mapping the bit sequence output by rate matching to the third resource.

[0162] Method 2: Generate the first signal by punching. Exemplarily, in this 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 based on the total number of REs included in the second resource, the modulation order of the first signal, and the number of layers (or transmission layers or streams) of the first signal. For example, the total number of coded bits satisfies the following relationship: G = N RE,2 ×Q m ×N L

[0165] Among them, N RE,2 Indicates the total number of REs included in the second resource. m Indicates the modulation order of the first signal. N L Indicates the layer number of the first signal.

[0166] 2) Channel coding and rate matching are performed on the uplink TB according to the total number of coded bits G.

[0167] 3) Mapping the bit sequence output by the rate matching to the second resource.

[0168] 4) Discard the bits on the REs in the second resource that overlap with the first resource.

[0169] 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 the 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.

[0170] 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.

[0171] It should be noted that there is no temporal order for step S904 and step S902. Step S902 may be performed first, followed by step S904; or step S904 may be performed first, followed by step S902; or step S902 and S904 may be performed simultaneously. This application does not impose any specific restrictions on this.

[0172] In one possible implementation, the first network device may further send a downlink signal (referred to as a 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 a fourth signal) to the second network device, and accordingly, the second network device receives the fourth signal from the fourth terminal device.

[0173] 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.

[0174] 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 can also measure the inter-base station CLI on the first resource.

[0175] Optionally, after determining the first resource or the first set of resources, the first network device may send third information to the second network device, where the third information indicates the first resource or the first set of resources. After receiving the third information, the second network device may send fourth information to the terminal device served by the second network device to indicate the first resource, and may further instruct the terminal device not to send uplink signals on the first resource.

[0176] Exemplarily, the terminal device served by the second network device may be a third terminal device or all terminal devices within the first cell. The first cell is the service cell for the third terminal device managed by the second network device. Furthermore, the implementation of the fourth information may refer to the description of the first information above, the behavior of the second network device may refer to the description of the first network device above, and the behavior of the fourth terminal device may refer to the description of the first terminal device above. The behavior of the second terminal device is similar to that of the third terminal device.

[0177] Optionally, the first network device may further indicate the first resource or the first resource set to other network devices other than the second network device. After learning the first resource or the first resource set, the other network devices 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.

[0178] 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.

[0179] In the measurement resource configuration method provided in the embodiment of the present application, 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, time unit, and sub-time unit of the first resource, thereby improving 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, avoiding 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.

[0180] Based on the above scheme, since the network device can know the time-frequency resource position of UCI, the network device can try to make the CLI measurement resource not overlap with the time domain position of UCI when configuring CLI measurement resources. 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 hop of PUSCH, so that the network device can perform CLI measurement before and after each frequency hop, and can flexibly support PUSCH frequency hopping, thereby improving the measurement performance in the PUSCH frequency hopping scenario.

[0181] The above describes the overall process of the configuration method of the measurement resource provided in the embodiment of the present application. The following describes the first resource and the first information in detail.

[0182] In one 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 repetition offset) of the first resource, an offset (or repetition 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.

[0183] 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 accordingly, the value of the offset can be offset = 0, 1, ..., T-1. The units of the period and the offset can be time units. The 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 among 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.

[0184] In the case where the first information indicates the sub-time unit where the first resource is located:

[0185] 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 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.

[0186] 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".

[0187] For example, taking the time unit as a time slot, the sub-time unit as an OFDM symbol, X equal to 14, and the first value equal to "1", when the first bitmap is {0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 0, 0}, the OFDM symbols indicating that 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 symbols indexed 2-11 in the time slot.

[0188] As another possible implementation, the first information may include a second bitmap. 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 units used to carry DMRS. That is, the Y bits in the second bitmap 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 be referred to the aforementioned related description and will not be repeated here.

[0189] For example, taking the time unit as a time slot, the sub-time unit as an OFDM symbol, X equal to 14, the first value equal to "1", and the indexes of the 14 OFDM symbols in the time slot as 0-13, assuming that the OFDM symbols with indexes 2 and 3 are used to carry DMRS, then Y equals 12, 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, 0, 0}, it indicates that the first resource is the OFDM symbols with indexes 4-11 in the time slot.

[0190] In a possible implementation, when the first resource is within the first time domain, the PUSCH in the embodiment of the present application may have the following four situations:

[0191] Case 1: No PUSCH repetition.

[0192] In this case 1, the PUSCH is usually located within a time unit, that is, the time domain resource where the PUSCH is located is located within a time unit, and the PUSCH within the time unit can be understood as one PUSCH. In this case, the first time domain range is the time domain position of the PUSCH within a time unit, which can also be understood as: the first time domain range is the time domain position of the PUSCH.

[0193] For example, as shown in (a) of FIG10 , taking a time slot as the time unit and an OFDM symbol as the sub-time unit, it is assumed that PUSCH#1 is transmitted in time slot 1 and occupies OFDM symbols 1-13 in time slot 1, and another PUSCH#2 is transmitted in time slot 2 and occupies 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.

[0194] Case 2: PUSCH repetition type A:

[0195] In PUSCH repetition type A, the PUSCH is repeated K times, and only once in a time unit. That is, the PUSCH is repeated K times in K time units, and the time domain position of the PUSCH in each time unit is the same. K is a positive integer.

[0196] In a possible implementation, PUSCH repetition K times can be understood as PUSCH transmission K times in total. In this case, the first PUSCH transmission can also be understood as one PUSCH repetition.

[0197] In one possible implementation, K repetitions of the PUSCH can be understood as one PUSCH, and the time domain position of the PUSCH is located in K time units. In this case, the time domain position of the 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 one time unit, which can be understood as: the first time domain range is the time domain position of the repetition in each time unit in PUSCH repetition type A.

[0198] 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.

[0199] For example, as shown in (b) of FIG10 , taking the time unit as a time slot, the sub-time unit as an OFDM symbol, and K equal to 3, that is, the PUSCH is repeated three times in three time slots, assuming that OFDM symbols 2-9 in each of time slots 1-3 are used to carry the 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 each constitute a first time domain range. That is, it can be considered that there are three first time domain ranges in this scenario.

[0200] Case 3: PUSCH repetition type B:

[0201] In one possible implementation, in PUSCH repetition type B, the PUSCH is repeated K times, with at least one repetition in one time unit. For example, there may be two PUSCH repetitions in one time unit. That is, the 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.

[0202] Exemplarily, in PUSCH repetition type B, the network device may first indicate the nominal repetition time domain position and the nominal repetition number, for example, indicating the starting OFDM symbol, the number of consecutive OFDM symbols, and the nominal repetition number of the time domain position of the nominal repetition within the time slot. Starting from the second nominal repetition (or 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. For example, if the starting OFDM symbol of the time domain position of the first nominal repetition within the time slot is symbol 0, the number of consecutive OFDM symbols is 6, and the nominal repetition number is 4, the time domain resources of the nominal repetition may be as shown in (c) of FIG10 .

[0203] Subsequently, the terminal device can determine the actual repeated time domain position in the nominal repeated time domain position for PUSCH retransmission. The actual repeated time domain position may include the time domain position in the nominal repeated time domain position except the invalid 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 can serve as the boundaries of the actual PUSCH repetition.

[0204] For example, as shown in (c) of FIG10 , OFDM symbols 2 and 5 in time slot 1, and OFDM symbol 5 in time slot 2 are configured as downlink symbols, and OFDM symbols 6 and 7 in time slot 1, and OFDM symbols 6 and 7 in time slot 2 are configured as invalid symbols. Based on this, there are 7 actual PUSCH repetitions in the example shown in (c) of FIG10 .

[0205] In one 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 PUSCH repetition type B.

[0206] Optionally, the actual repeated time domain position 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 of the actual PUSCH repetition 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.

[0207] For example, as shown in (c) in Figure 10, 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 1st actual PUSCH repetition, that is, OFDM symbol 0 and OFDM symbol 1 in time slot 1, and so on, which will not be repeated.

[0208] Case 4: Transport block (TB) spanning multiple time units.

[0209] Exemplarily, when the time unit is a time slot, this fourth situation can be understood as a transport block over multi-slot (TBoMS).

[0210] In a TB scenario spanning multiple time units, multiple time units are used to transmit a larger TB. A portion of the TB is transmitted in each time unit. In this case, the transmission of the entire TB can be considered 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 spanning multiple time units in each time unit.

[0211] For example, as shown in (d) of Figure 10, taking the time unit as a time slot, the sub-time unit as an OFDM symbol, and the TB being transmitted within 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 TBs, then the time domain position of the entire PUSCH can be considered to include 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 each constitute a first time domain range. That is, it can be considered that there are two first time domain ranges in this scenario.

[0212] As a possible implementation, frequency hopping within a 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 hop. For example, the example shown in FIG7 can be considered to have two frequency hops, namely the first hop and the second hop.

[0213] For example, taking a time slot as the time unit, i.e., 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:

[0214] Where i=0 and i=1 refer to the first hop and the second hop respectively. start Refers to the starting resource block (RB) of PUSCH within the uplink bandwidth. The uplink bandwidth can be, for example, the uplink bandwidth part (BWP) or the uplink carrier. 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.

[0215] As a possible implementation manner, the time domain position corresponding to each frequency hopping within the PUSCH can also be understood as: the time domain position corresponding to each frequency hopping of the PUSCH within a time unit, and / or the time domain position corresponding to each frequency domain position of the PUSCH within a time unit. The frequency hopping of the PUSCH within a time unit can refer to the relevant description of the frequency hopping within the above time slot, and will not be repeated here.

[0216] Optionally, in the above case, 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.

[0217] For example, as shown in (a) in Figure 11, 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 in time slot 1, occupying OFDM symbols 1-13 in 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.

[0218] Optionally, in the above case 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.

[0219] For example, as shown in (b) in Figure 11, taking the time unit as the time slot, the sub-time unit as the OFDM symbol, and K equal to 3 as an example, assuming that the OFDM symbols 2-9 in each time slot in time slots 1-3 are used to carry PUSCH, and the frequency domain position of the PUSCH in the OFDM symbols 2-5 in each time slot is frequency domain position 1, and the frequency domain position of the PUSCH in the OFDM symbols 6-9 is frequency domain position 2, then the OFDM symbols 2-5 in each time slot can be understood as a first time domain range, and the 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.

[0220] Optionally, in the above-mentioned fourth situation, if the TB spanning 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. Please refer to the example described in (b) in the above Figure 11, which will not be repeated here.

[0221] When 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 within which the first resource is located, and N is a positive integer. For example, if N is 1, then one sub-time unit within the first time domain range is used for CLI measurement.

[0222] 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 one time slot including 14 OFDM symbols (indexed 0-13) as an example:

[0223] When 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 within the time slot, if the indexes of the N sub-time units are the indexes of the sub-time units within the time unit, then the indexes of the N sub-time units may be within 0-13. If the indexes of the N sub-time units are the indexes of the sub-time units within the first time domain range, then the first time domain range includes 13 sub-time units, and the indexes of the N sub-time units may be within 0-12.

[0224] 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 within 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.

[0225] 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.

[0226] When the first time domain range is the time domain position corresponding to each frequency hop within the PUSCH, the positions of the N sub-time units corresponding to each frequency hop within the first time domain range may be the same. In this case, 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 within each first time domain range is the sub-time unit where the first resource is located. The first information may include an index n.

[0227] Alternatively, the positions of the N sub-time units corresponding to each frequency hop within the first time domain range may be different. In this 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 one 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 indicate 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.

[0228] 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.

[0229] When the first resource is located within the first time domain, the time domain location of the first resource may satisfy at least one of the following conditions:

[0230] 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.

[0231] For example, as shown in (a) in Figure 12, 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.

[0232] 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) and will not be repeated here.

[0233] 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.

[0234] For example, as shown in (b) of FIG12 , 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, 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. Alternatively, as shown in (c) of FIG12 , 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.

[0235] 4) The time domain position of the first resource is the first sub-time unit not used to carry DMRS and after the first sub-time unit used to carry DMRS in the first time domain range.

[0236] For example, as shown in FIG13 , taking the case where the time domain position of the PUSCH within a time slot includes OFDM symbols 1-13, i.e., the first time domain range includes OFDM symbols 1-13, and 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 after the first sub-time unit used to carry DMRS in the first time domain range that is not used to carry DMRS is OFDM symbol 5.

[0237] 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.

[0238] 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.

[0239] For example, as shown in Figure 14, 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.

[0240] 7) The time domain position of the first resource is the first sub-time unit after the first sub-time unit used to carry UCI in the first time domain range, and the first sub-time unit not used to carry DMRS and different from the sub-time unit carrying UCI. Please refer to the relevant description of condition 6) and will not be repeated here.

[0241] Optionally, when the time domain position of the first resource satisfies at least one of the above conditions, the protocol may define the above seven conditions or the first network device may pre-configure the above seven conditions to the first terminal device. In this scenario, the first information may indicate at least one of the above seven conditions, for example, the first information includes an index of at least one condition. Alternatively, the protocol may define one of the above seven conditions. In this case, the first network device and the first terminal device default to the condition satisfied by the time domain position of the first resource as the condition defined by the protocol. The first information may indicate the frequency domain position of the first resource, but not the time domain position of the first resource.

[0242] Optionally, UCI may meet at least one of the following requirements:

[0243] UCI is hybrid automatic repeat request-acknowledgement (HARQ-ACK) information;

[0244] UCI includes HARQ-ACK information and channel state information-reference signal (CSI-RS) part 1;

[0245] 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);

[0246] UCI includes HARQ-ACK information, CSI-RS part 1, CSI-RS part 2, and joint coding of HARQ-ACK and CG-UCI;

[0247] UCI is the joint coding of HARQ-ACK and CG-UCI;

[0248] UCI includes HARQ-ACK information and joint coding of HARQ-ACK and CG-UCI.

[0249] Optionally, the above Figures 12 to 14 are illustrated using 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 hop of the PUSCH, the time domain position of the PUSCH in Figures 12 to 14 can be replaced with the time domain position corresponding to one frequency hop for understanding, and no further details will be given here.

[0250] In one possible implementation, first resources that periodically repeat in the time domain (i.e., first-type measurement resources) and first resources located within the first time domain (referred to as second-type measurement resources) may coexist, or one of the two types of measurement resources may exist within a certain period of time. That is, the first network device may be configured with both the first-type measurement resources and the second-type measurement resources simultaneously, or may be configured with only the first-type measurement resources or only the second-type measurement resources within a certain period of time.

[0251] In one 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 a DMRS and / or the fourth resource is used to carry UCI. In other words, the time domain position of the first resource does not overlap with the time domain position of the DMRS and / or UCI.

[0252] Based on this possible implementation method, when the time domain position of the first resource does not overlap with the time domain position of the 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 the UCI, thereby improving the transmission performance of the uplink data and / or UCI.

[0253] In a possible implementation, if the time domain location of the CLI measurement resource overlaps with the fourth resource, processing may be performed according to the following criteria:

[0254] 1) Abandoning the CLI measurement resources, or considering the CLI measurement resources to be an empty set. In this scenario, it can be considered that DMRS and / or UCI transmission is prioritized and CLI measurement is abandoned.

[0255] 2) Discard the portion of the CLI measurement resource that overlaps with the fourth resource.

[0256] As a possible implementation, the first network device can indicate the CLI measurement resource to the first terminal device, but there may be a part in the measurement resource that overlaps with the fourth resource. Then the first terminal device and the first network device can discard the part of the original CLI measurement resource that overlaps with the fourth resource, and use the part that does not overlap with the fourth resource for CLI measurement.

[0257] That is, the first information indicating the first resource may include: the first information indicating a fifth resource, the fifth resource being used for CLI measurement, i.e., the fifth resource being the original CLI measurement resource. The fifth resource has a portion that overlaps with the fourth resource. In this case, the first resource includes a resource in the fifth resource that does not overlap with the fourth resource.

[0258] As a possible implementation, the first resource may further include M sub-time units following 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, resources of a corresponding size may be added as new CLI measurement resources.

[0259] For example, as shown in FIG15 , taking a time slot as the time unit and an OFDM symbol as the sub-time unit, 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 initially include OFDM symbols 1-2 and OFDM symbols 5-6. Furthermore, two more OFDM symbols (e.g., 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.

[0260] Based on the above criteria, 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.

[0261] The above describes the time domain location of the first resource. The following describes the frequency domain location of the first resource. First, regarding the frequency domain bandwidth of the first resource:

[0262] 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.

[0263] 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 are the same.

[0264] In a third possible implementation, the frequency domain bandwidth of the first resource may be an uplink bandwidth part (BWP), or an uplink carrier, or an uplink subband (such as an uplink subband in an SBFD scenario).

[0265] In the second and third possible implementations described above, 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 uplink BWP or the bandwidth of the uplink carrier or the uplink subband.

[0266] The resource elements (REs) occupied by the first resource in the frequency domain bandwidth may be distributed in a comb-tooth pattern. For example, the number of comb teeth may be 2. Other comb-tooth numbers, such as 4, are also possible, and are not specifically limited in this application. The first resource has the same position within each RB, meaning that the first resource occupies the same REs within each RB.

[0267] In one possible implementation, the first resource occupies P REs within an 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 an RB, and P and Q are positive integers. Furthermore, P is a divisor of Q.

[0268] 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.

[0269] 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:

[0270] Mode 1: The first information includes a first field. When the value of the first field is a third value, the frequency domain position of the first resource within an RB is an RE with an even index, that is, the first resource occupies an even-indexed RE within an RB. When the value of the first field is a fourth value, the frequency domain position of the first resource within an RB is an odd-indexed RE, that is, the first resource occupies an odd-indexed RE within an RB.

[0271] 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.

[0272] 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 within an RB; when k = 1, the first resource occupies the RE with an odd index within an RB.

[0273] For example, as shown in Figure 16, where the time unit is a time slot and the sub-time unit is an OFDM symbol, the black-filled portion in the figure can be understood as the time-frequency position of the first resource. In Figure 16, the first resource is located in OFDM symbol 4 and OFDM symbol 9 in the time domain and in an even-indexed RE within an RB in the frequency domain.

[0274] As a second possible implementation, the index i of the RE occupied by the first resource in the RB satisfies: i=nL+k.

[0275] 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.

[0276] For example, taking L = 4 and k = 2, the first resource occupies REs indexed 2, 6, and 10 within the RB. As shown in Figure 17, taking the time unit as a time slot and the sub-time unit as an OFDM symbol as an example, the black-filled portion in the figure can be understood as the time-frequency location of the first resource. In Figure 17, the first resource is located in OFDM symbols 4 and 9 in the time domain and in REs indexed 2, 6, and 10 within the RB in the frequency domain.

[0277] It is understandable that, regarding the REs occupied by the first resource within 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.

[0278] 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.

[0279] For example, as shown in Figure 16 or Figure 17, assuming that the first resource and the second resource overlap on OFDM symbol 4 and OFDM symbol 9, then in the scenario shown in Figure 16, REs indexed as odd numbers on OFDM symbol 4 and OFDM symbol 9 can be used to send the first signal, and in the scenario shown in Figure 17, REs indexed as 0, 1, 3, 4, 5, 7, 8, 9, and 11 on OFDM symbol 4 and OFDM symbol 9 can be used to send the first signal.

[0280] 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. Exemplarily, taking Q equal to 12 and L equal to 2 as an example, assuming that in the scenario shown in Figure 16 or Figure 17, the second resource also includes OFDM symbol 5, then 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.

[0281] 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.

[0282] It should be noted that in the embodiments of the present application, the time domain position allocation and 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.

[0298] Among them, all relevant contents of each step involved in the above method embodiment can be referred to the functional description of the corresponding functional module and will not be repeated here.

[0299] In the present application, the communication device 180 may be presented in the form of various functional modules divided in an integrated manner. The "module" here may refer to a specific application-specific integrated circuit (ASIC), a circuit, a processor and memory that executes one or more software or firmware programs, an integrated logic circuit, and / or other devices that can provide the above functions.

[0300] In some embodiments, when the communication device 180 in Figure 18 is a chip or a chip system, the function / implementation process of the transceiver module 1802 can be implemented through the input and output interface (or communication interface) of the chip or chip system, and the function / implementation process of the processing module 1801 can be implemented through the processor (or processing circuit) of the chip or chip system.

[0301] Since the communication device 180 provided in this embodiment can execute the above method, the technical effects that can be obtained can refer to the above method embodiments and will not be repeated here.

[0302] As a possible product form, the terminal device or network device described in the embodiments of the present application can also be implemented using the following: one or more field programmable gate arrays (FPGAs), programmable logic devices (PLDs), controllers, state machines, gate logic, discrete hardware components, any other suitable circuits, or any combination of circuits that can perform the various functions described throughout this application.

[0303] As another possible product form, the terminal device or network device described in the embodiment of the present application can be implemented by a general bus architecture. For ease of explanation, refer to Figure 19, which is a structural diagram of a communication device 1900 provided in an embodiment of the present application, and the communication device 1900 includes a processor 1901 and a transceiver 1902. The communication device 1900 can be a network device, or a chip or chip system therein; or, the communication device 1900 can be a terminal device, or a chip or module therein. Figure 19 only shows the main components of the communication device 1900. In addition to the processor 1901 and the transceiver 1902, the communication device may further include a memory 1903, and an input and output device (not shown in the figure).

[0304] Optionally, processor 1901 is primarily used to process communication protocols and communication data, as well as control the entire communication device, execute software programs, and process software program data. Memory 1903 is primarily used to store software programs and data. Transceiver 1902 may include a radio frequency circuit and an antenna. The radio frequency circuit is primarily used to convert baseband signals into radio frequency signals and process radio frequency signals. The antenna is primarily used to transmit and receive radio frequency signals in the form of electromagnetic waves.

[0305] Optionally, the processor 1901 , the transceiver 1902 , and the memory 1903 may be connected via a communication bus.

[0306] When the communication device is powered on, processor 1901 can read the software program in memory 1903, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, processor 1901 performs baseband processing on the data to be sent and outputs the baseband signal to the radio frequency circuit. The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves via the antenna. When data is sent to the communication device, the radio frequency circuit receives the radio frequency signal via the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to processor 1901. Processor 1901 converts the baseband signal into data and processes the data.

[0307] In another implementation, the RF circuit and antenna may be provided independently of the processor performing baseband processing. For example, in a distributed scenario, the RF circuit and antenna may be remotely arranged independent of the communication device.
