[0059] Subband non-overlapping full-duplex

[0060] SBFD is a communication technology designed to improve spectrum efficiency and the performance of communication systems. In 5G NR TDD, insufficient uplink resources lead to weak uplink coverage, high uplink latency, and inadequate uplink capacity. 3GPP introduced SBFD technology, which allows simultaneous transmission and reception of data in different subbands within the same subframe / slot / symbol. This technology is primarily used on the base station side, while the terminal device side maintains its current state, meaning that only transmission or reception of data is supported within a single subframe / slot / symbol.

[0061] As shown in Figure 1, an intermediate sub-band in a downlink time domain unit is configured as an uplink sub-band. This downlink time domain unit can be a subframe, a time slot, or a symbol.

[0062] In a downlink or flexible subframe / slot / symbol, an intermediate subband is configured as an uplink subband. When the uplink (UL) link occupies the full bandwidth, it is called dynamic time division duplex (dynamic TDD). This can be regarded as an extreme case of SBFD, which can dynamically adapt the transmission direction of time resources based on time slots.

[0063] Furthermore, according to the current 3GPP agreement, SBFD subbands include: Uplink subbands (UL subbands) can only be configured on downlink time-domain symbols (DL symbols) and / or flexible time-domain symbols configured in TDD-UL-DL-ConfigCommon. Downlink subbands (DL subbands) can only be configured on uplink time-domain symbols (UL symbols) and / or flexible time-domain symbols configured in TDD-UL-DL-ConfigCommon. Figure 2 shows a possible frame structure for SBFD. In Figure 2, D represents the downlink time-domain symbol, and U represents the uplink time-domain symbol.

[0064] The relevant technology only supports semi-static SBFD, which means that the subframe / time slot / symbol where the SBFD is located, as well as the bandwidth and location of the uplink and downlink subbands, are configured in a semi-static manner and cannot be changed dynamically. In this case, base stations of the same operator in different cells, especially neighboring cells, usually have the same configuration.

[0065] Cross-link interference reporting

[0066] Cross-link interference (CLI) refers to the interference that may occur when uplink transmission in one cell can interfere with downlink reception in another cell when different TDD uplink and downlink modes are used between different cells. CLI measurements mainly fall into two categories:

[0067] (1) Sounding Reference Signal-Reference Signal Received Power (SRS-RSRP): The user equipment (UE) measures the SRS-RSRP on the sounding reference signal (SRS) resources from interfering UEs. This measurement is used to assess the strength of the interfering signal.

[0068] (2) Cross-Link Interference-Received Signal Strength Indicator (CLI-RSSI): Also known as interference signal strength, this measures the total received power observed by the UE on the Received Signal Strength Indicator (RSSI) resource. This includes power from co-channel and non-serving cells, adjacent channel interference, and thermal noise, etc.

[0069] CLI-RSSI, as a method for measuring cross-link interference signals, has been defined in relevant technologies. However, this type of measurement is performed during a measurement gap. During this gap, neither the terminal nor the base station transmits or receives any signals. Therefore, measurements on empty resource elements (REs) during this phase are not affected by signals transmitted or received within the same cell, but rather by interference signals from other cells. The duplexing technologies employed or discussed in relevant technologies include dynamic TDD, which flexibly changes the transmission direction of each time slot, and SBFD, which embeds uplink subbands into downlink time slots. Both technologies face the problem of cross-link interference between terminals due to the flexibility of terminal configurations. That is, when adjacent terminals are configured with different transmission directions, the terminal receiving downlink data will be affected by uplink transmission interference from adjacent terminals.

[0070] Related technologies have established a mechanism for physical layer (Layer 1, L1) CLI measurement and reporting, which aims to report cross-link interference in a timely manner to facilitate base station scheduling. The following protocol has been formed, which includes CLI-RSSI measurement and reporting, that is, measuring the received signal strength in the empty RE on the DL subband as CLI-RSSI and reporting it.

[0104] -CLI measurement accuracy requirements

[0105] Figure 3 illustrates a schematic diagram of a communication system provided in an exemplary embodiment of this application. The communication system includes a network device 320, a terminal device 340, and / or a terminal device 342.

[0106] The network device 320 in this embodiment provides wireless communication functionality. This network device 320 includes, but is not limited to: an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a Home Evolved Node B (or Home Node B, HNB), a Baseband Unit (BBU), an Access Point (AP) in a Wi-Fi system, a wireless relay node, a wireless backhaul node, a Transmission Point (TP), or a Transmission and Reception Point (TRP), etc. It can also be used for next-generation Node B (Next Generation Node) systems in 5G mobile communication systems. B, gNB) or transmission point (TRP or TP), or, in a 5G system, one or a group of antenna panels (including multiple antenna panels) of a base station, or, network nodes constituting a gNB or transmission point, such as baseband unit (BBU) or distributed unit (DU), or base stations in Beyond Fifth Generation (B5G) mobile communication systems or 6th Generation (6G) mobile communication systems, or core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, etc., or serving cell, primary cell (PCell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (SCell), neighboring cell, etc. of terminal equipment.

[0107] The terminal devices 340 and 342 in this application embodiment can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user apparatus. This terminal includes, but is not limited to: handheld devices, wearable devices, in-vehicle devices, and IoT devices, such as: mobile phones, tablets, e-readers, laptops, desktop computers, televisions, game consoles, mobile internet devices (MID), augmented reality (AR) terminals, virtual reality (VR) terminals, mixed reality (MR) terminals, wearable devices, controllers, electronic tags, controllers, wireless terminals in industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, smart home, remote medical surgery, cellular phones, cordless phones, Session Initiation Protocol (SIP) phones, and wireless local loops. Loop (WLL) stations, personal digital assistants (PDAs), set-top boxes (STBs), customer premises equipment (CPEs), etc.

[0108] Terminal device 340 and network device 320 communicate with each other via some air interface technology. For example, there is a downlink communication scenario between terminal device 340 and network device 320. Terminal device 342 and network device 320 also communicate with each other via some air interface technology. For example, there is an uplink communication scenario between terminal device 342 and network device 320. Uplink communication refers to terminal device 342 sending signals to network device 320; downlink communication refers to network device 320 sending signals to terminal device 340.

[0109] In this embodiment, the first resource 360 ​​and the second resource 362 are used for communication and measurement between the terminal device 340 and other devices, respectively. For example, the first resource 360 ​​is the downlink channel resource from the network device 320 received by the terminal device 340, and the second resource 362 is the resource used by the terminal device 342 for interference measurement. For example, the first resource 360 ​​and the second resource 362 have an overlapping portion 364, meaning that downlink channel transmission and interference measurement conflict.

[0110] In scenarios where SBFD technology is introduced, taking CLI-RSSI measurement as an example of interference measurement, terminal device 340 aims to measure the cross-link interference strength of its uplink signal on the second resource 362. However, if network device 320 simultaneously sends a downlink signal to terminal device 340 on the first resource 360, the signal measured on the overlapping resource 364 will be a mixture of uplink and downlink signals, not just the uplink signal from terminal device 342, leading to inaccurate CLI-RSSI measurement results. Therefore, how to resolve and handle such conflicts, and how to achieve accurate CLI-RSSI measurement, are urgent problems to be solved.

[0111] Figure 4 illustrates a flowchart of a downlink channel receiving method provided in an exemplary embodiment of this application. The method is performed by a terminal device and includes:

[0112] Step 402: If the first resource overlaps with the second resource, execute the first action;

[0113] The first resource is used to carry the first downlink channel. Optionally, the first resource includes frequency domain resources and / or time domain resources. When the first resource includes frequency domain resources, it can be one or more of a Physical Resource Block (PRB) and a subcarrier. When the first resource includes time domain resources, it can be one or more of a radio frame, subframe, half-frame, slot, symbol group, and symbol. When the first resource includes time-frequency resources, it can be one or more of a Resource Element (RE) and a Resource Grid. In some embodiments, the first resource can also be characterized using resource units newly defined in 6G and subsequent evolutions.

[0114] The first downlink channel includes one or more of the Physical Downlink Shared Channel (PDSCH) and the Physical Downlink Control Channel (PDCCH). In some embodiments, the first downlink channel also includes any channel in the downlink direction newly defined in 6G.

[0115] The second resource is used for interference measurement. Optionally, the second resource includes frequency domain resources and / or time domain resources. When the second resource includes frequency domain resources, it can be one or more of a PRB (Paragraph Repository Block), a subcarrier, etc. When the second resource includes time domain resources, it can be one or more of a radio frame, a subframe, a half-frame, a time slot, a symbol group, a symbol, etc. When the second resource includes time-frequency resources, it can be one or more of a RE (Resource Array) and a resource grid. In some embodiments, the second resource can also be characterized using resource units newly defined in 6G and subsequent evolutions.

[0116] In some embodiments, the second resource is a resource configured for measuring interference for any terminal device within the serving cell and / or neighboring cells of the terminal device.

[0117] In some embodiments, the results of interference measurement can be characterized by one or more of CLI-RSSI and Sounding Reference Signal-Reference Signal Received Power (SRS-RSRP). In the embodiments of this application, interference measurement refers to the measurement of CLI-RSSI interference.

[0118] Overlap of the first and second resources: Overlap includes complete overlap or partial overlap. Complete overlap means that the first and second resources are the same size and also completely identical in position. For example, Figure 5 shows a schematic diagram of complete overlap of the first resource 360 ​​and the second resource 362 provided in an exemplary embodiment of this application.

[0119] Optionally, partial overlap includes at least one or more of the following three cases: First case: All resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362, as shown in Figure 6. Second case: A portion of the resources of the first resource 360 ​​overlaps with all resources of the second resource 362, as shown in Figure 7. Third case: A portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362, as shown in Figure 8.

[0120] The first line is used to resolve conflicts when the first resource and the second resource overlap. In some embodiments, the first line prioritizes ensuring downlink reception of the first downlink channel. In some embodiments, the first line prioritizes ensuring the accuracy of interference measurements. In some embodiments, the first line ensures that downlink reception and interference measurements of the first downlink channel are performed simultaneously without interference.

[0121] Optionally, the first action includes one or more of the following six actions: Action 1: Receiving a first downlink channel in all or part of the resources of the first resource; Action 2: Performing interference measurement in the portion of the second resource that does not overlap with the first resource; Action 3: Canceling the reception of the first downlink channel in all or part of the resources of the first resource; Action 4: Canceling the performance of interference measurement in all or part of the resources of the second resource; Action 5: De-enabling interference measurement in all or part of the resources of the second resource; Action 6: Re-determining a third resource for interference measurement, wherein the third resource is offset from the second resource in the time domain by a first number of time domain units, and / or offset from the second resource in the frequency domain by a second number of frequency domain units; wherein the first number and the second number are positive integers. The first number and / or the second number are agreed upon by the communication protocol or configured by the second information.

[0122] In some embodiments, the second information refers to signaling. In some embodiments, a portion of the first resource refers to the first resource in which the first resource 360 ​​and the second resource 362 partially or completely overlap. In other embodiments, a portion of the first resource refers to the portion of the first resource in which the first resource 360 ​​and the second resource 362 do not overlap.

[0123] In summary, the method provided in this embodiment is used to perform a first action when the first resource and the second resource overlap, in order to resolve the conflict between downlink reception and interference measurement, thereby prioritizing the reception of the first downlink channel; and / or prioritizing the correct interference measurement.

[0124] For behavior one: The terminal device receives the first downlink channel in all or part of the resources of the first resource. In this case, the resources of the first resource do not overlap with the second resource, or the resources of the first resource do not include the second resource.

[0125] For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the first downlink channel is received in all resources of the first resource 360. For example, as shown in FIG7, a portion of the resources of the first resource 360 ​​overlaps with all resources of the second resource 362. The first downlink channel is received in the portion of the first resource 360 ​​excluding the second resource 362. For example, as shown in FIG8, all resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362. The first downlink channel is received in the portion of the first resource 360 ​​that does not overlap with the second resource 362.

[0126] For example, FIG9 shows a time-frequency resource diagram of a first resource 360 ​​and a second resource 362 provided in an exemplary embodiment of this application. As shown in FIG9, PDSCH is a portion of the first resource, which is the non-overlapping portion of the first resource 360 ​​and the second resource 362. RB-level CLI-RSSI resource is the second resource, which occupies a plurality of consecutive RBs on a plurality of consecutive symbols. For example, FIG10 shows a time-frequency resource diagram of a first resource 360 ​​and a second resource 362 provided in an exemplary embodiment of this application. As shown in FIG10, RE-level CLI-RSSI resource is the second resource 362, which occupies a plurality of discrete REs on a symbol. The terminal device can implement reception of the first downlink channel on a portion of the resources excluding the second resource 362, i.e., a portion of the resources of the first resource 360. For example, in some embodiments, the portion of the resources excluding the second resource 362 may refer to the PDSCH resource excluding the RB-level CLI-RSSI resource. In some embodiments, the portion of the resources excluding the second resource 362 may refer to the PDSCH resource excluding the RE-level CLI-RSSI resource.

[0127] In some embodiments, the second resource 362 is configured by first information, and a portion of the resources of the first resource 360 ​​does not include all the resources configured by the first information. Optionally, the first information is higher-layer signaling or downlink control signaling, used to indicate the time-domain and / or frequency-domain configuration of the second resource 362. Optionally, a portion of the resources of the first resource 360 ​​refers to a portion of the resources that do not overlap with the second resource 362 and are used to carry the first downlink channel. The portion of the resources of the first resource 360 ​​does not include all the resources configured by the first information, that is, this portion of the resources does not include all symbols and all subcarriers configured by the first information.

[0128] In some embodiments, a portion of the resources of the first resource 360 ​​does not include the overlapping portion of the second resource 362 and the fourth resource, where the fourth resource is a zero-power signal recourse. The fourth resource is configured by higher-layer signaling or downlink control signaling. In some embodiments, interference signal measurements are performed on the overlapping portion of the second resource 362 and the fourth resource, while the non-overlapping portion of the second resource 362 and the fourth resource supports reception of the first downlink channel. For example, FIG11 shows a time-frequency resource diagram of the first and second resources provided in an exemplary embodiment of this application. As shown in FIG11, the second resource 362 is configured on PRB n to PRB m of symbol 1, and the second resource 362 overlaps with the fourth resource on a portion of the REs in PRB n and PRB m. The overlapping REs are treated as unavailable resources, and the first downlink channel is received at locations where unavailable resources are not included. Optionally, in some embodiments, the REs in PRB n to PRB m occupied by the fourth resource are treated as unavailable resources, and the first downlink channel (e.g., PDSCH) is received at other locations where unavailable resources are not included. Optionally, all fourth resources on symbol 1 are treated as unavailable resources, and the first downlink channel is received at other locations that do not contain unavailable resources. Optionally, in some embodiments, if a second resource 362 overlaps with a fourth resource, all fourth resources are treated as unavailable resources, and the first downlink channel is received at other locations that do not contain unavailable resources.

[0129] In summary, the method provided in this embodiment receives the first downlink channel on the first resource in the non-overlapping portion of the first resource 360 ​​and the second resource 362, thus prioritizing the reception of the first downlink channel.

[0130] For behavior two: The terminal device performs interference measurement on the portion of the second resource that does not overlap with the first resource. In some embodiments, a portion of the first resource does not overlap with the second resource, or a portion of the first resource does not include the second resource.

[0131] For example, FIG9 illustrates a time-frequency resource map of a first resource 360 ​​and a second resource 362 provided in an exemplary embodiment of this application. As shown in FIG9, PDSCH is a portion of the first resource 360, and the RB-level CLI-RSSI resource is the second resource 362. The second resource 362 does not overlap with the first resource 360 ​​at consecutive positions of PRB n to PRB m on symbols 1 to 4, i.e., interference measurements are performed at consecutive positions of PRB n to PRB m on symbols 1 to 4. As shown in FIG10, the RE-level CLI-RSSI resource is the second resource 362. The second resource 362 does not overlap with the first resource 360 ​​on a plurality of discrete REs on symbol 1, i.e., interference measurements are performed on a portion of the REs on PRB n to PRB m on symbol 1. The terminal device can perform interference measurements on a portion of the resources excluding the first resource 360, i.e., a portion of the resources of the second resource 362.

[0132] In some embodiments, a portion of the resources of the second resource 362 overlaps with the first resource 360. For example, as shown in FIG6, all the resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362, and interference measurement is performed on the portion of the second resource 362 excluding the first resource 360. In some embodiments, a downlink channel is received on the portion of resource 364 where the first resource 360 ​​and the second resource 362 overlap. In other embodiments, no operation is performed on the portion of resource 364 where the first resource 360 ​​and the second resource 362 overlap. In some embodiments, a first downlink channel is received on the first resource 360, and interference measurement is performed on the portion of the second resource 362 that does not overlap with the first resource 360; in other embodiments, neither the first downlink channel is received on the first resource 360, nor is interference measurement performed on the first resource 360, but interference measurement is performed only on the portion of the second resource that does not overlap with the first resource. For example, as shown in FIG7, all the resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362, and interference measurement is performed on the portion of the second resource 362 that does not overlap with the first resource 360, and a first downlink channel is received on the first resource 360. For example, as shown in FIG8, in some embodiments, a portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362, interference measurement is performed on the portion of the second resource 362 that does not overlap with the first resource 360, and the first downlink channel is received on all the resources of the first resource 360. In other embodiments, the first downlink channel is received on the portion of the first resource 360 ​​that does not overlap with the second resource 362, and interference measurement is performed on the entire second resource 362.

[0133] In summary, the method provided in this embodiment performs interference measurement on the second resource where the first resource 360 ​​and the second resource 362 do not overlap, thus prioritizing the accuracy of the interference measurement.

[0134] Regarding behavior three: The terminal device cancels the reception of the first downlink channel in all or part of the first resource.

[0135] In some embodiments, the terminal device cancels receiving the first downlink channel on all resources of the first resource 360. For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the terminal device cancels receiving the first downlink channel on all resources of the first resource 360 ​​and performs interference measurement.

[0136] In some embodiments, the terminal device cancels receiving the first downlink channel on a portion of the resources of the first resource 360. Optionally, the terminal device cancels receiving the first downlink channel on a portion of resources 364 where the first resource 360 ​​and the second resource 362 overlap. For example, as shown in FIG7, receiving the first downlink channel is canceled on the portion of resources 364 where the first resource 360 ​​and the second resource 362 overlap. In some embodiments, the terminal device performs interference measurement on the overlapping portion of resources 364. For example, as shown in FIG8, in some embodiments, a portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362. In the portion of resources 364 where the first resource 360 ​​and the second resource 362 overlap, receiving the first downlink channel is canceled, and the terminal device performs interference measurement on all resources of the second resource 362.

[0137] In summary, the method provided in this embodiment cancels the reception of the first downlink channel on the first resource 360 ​​where the first resource 360 ​​and the second resource 362 are wholly or partially overlapped, thus prioritizing the accuracy of interference measurement.

[0138] Regarding behavior four: The terminal device cancels the execution of interference measurement on all or part of the second resource.

[0139] In some embodiments, the terminal device cancels the interference measurement on all resources of the second resource 362. For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the terminal device cancels the interference measurement on all resources of the second resource 362 and receives a first downlink channel within all resources of the second resource 362. For example, as shown in FIG7, some resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the terminal device cancels the interference measurement on all resources of the second resource 362 and receives a first downlink channel within all resources of the second resource 362.

[0140] In some embodiments, the terminal device cancels interference measurement on a portion of the resources of the second resource 362. Optionally, the terminal device cancels interference measurement on a portion of resources 364 where the second resource 362 overlaps with the first resource 360. For example, as shown in FIG6, interference measurement is canceled on the portion of resources 364 where the first resource 360 ​​overlaps with the second resource 362. In some embodiments, the terminal device cancels interference measurement on the overlapping portion of resources 364 and receives a first downlink channel. For example, as shown in FIG8, in some embodiments, a portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362. Interference measurement is canceled on a portion of the resources of the second resource 362, i.e., the portion where the first resource 360 ​​overlaps with the second resource 362, and the terminal device receives a first downlink channel on all resources of the first resource 360.

[0141] In summary, the method provided in this embodiment cancels the interference measurement on the second resource where the first resource 360 ​​and the second resource 362 overlap in whole or in part, thus prioritizing the reception of the first downlink channel.

[0142] For behavior five: The terminal device disables interference measurement on all or part of the second resource.

[0143] In some embodiments, the terminal device enables interference measurement on all resources of the second resource 362. For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the terminal device enables interference measurement on all resources of the second resource 362 and receives a first downlink channel within all resources of the second resource 362. For example, as shown in FIG7, a portion of the resources of the first resource 360 ​​overlaps with all resources of the second resource 362. In some embodiments, the terminal device enables interference measurement on all resources of the second resource 362 and receives a first downlink channel within all resources of the second resource 362.

[0144] In some embodiments, the terminal device enables interference measurement on a portion of the resources of the second resource 362. Optionally, the terminal device enables interference measurement on a portion 364 where the second resource overlaps with the first resource. For example, as shown in FIG6, interference measurement is enabled on a portion 364 where the first resource 360 ​​overlaps with the second resource 362. In some embodiments, the terminal device enables interference measurement on the overlapping portion 364 and receives a first downlink channel. For example, as shown in FIG8, in some embodiments, a portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362, and interference measurement is disabled in the overlapping portion of the first resource 360 ​​and the second resource 362, while the terminal device receives the first downlink channel on all resources of the first resource 360. In some embodiments, the network device prioritizes the reception of the first downlink channel. FIG14 shows a time-frequency resource map of the first resource and the second resource provided in an exemplary embodiment of this application. For example, as shown in Figure 14, the second resource 362 used for measuring interference overlaps with the first resource 360 ​​on PRB n to PRB m of symbol 1. At this time, the network device enables interference measurement on a portion of the resources of the second resource 362, that is, the network device enables interference measurement on the resources where the first resource 360 ​​and the second resource 362 partially overlap.

[0145] In summary, the method provided in this embodiment enables interference measurement on the second resource where the first resource 360 ​​and the second resource 362 partially or completely overlap, thus prioritizing the reception of the first downlink channel.

[0146] For behavior six: A third resource is reassigned for interference measurement, offset from the second resource in the time domain by a first number of time-domain units, and / or offset from the second resource in the frequency domain by a second number of frequency-domain units; wherein the first and second numbers are positive integers. The first and / or second numbers are determined by the communication protocol or configured by the second information.

[0147] In some embodiments, the second information refers to signaling. In some embodiments, the second resource 362 is configured by the first information. Optionally, the first information is higher-layer signaling or downlink control signaling, used to indicate the time-domain configuration and / or frequency-domain configuration of the second resource 362. When the terminal device determines that the first resource 360 ​​overlaps with the second resource 362, a third resource for interference measurement is re-determined. The third resource is advanced or delayed by a first number of time-domain units in the time domain compared to the second resource 362, and / or offset by a second number of frequency-domain units in the frequency domain, so that the first resource 360 ​​and the re-determined third resource do not overlap. For example, as shown in FIG6, if all resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362, in some embodiments, the third resource is re-determined by advancing or delaying by a first number of time-domain units compared to the second resource 362 in the time domain, so that the first resource 360 ​​and the third resource do not overlap. In other embodiments, the third resource is re-determined by advancing or delaying by a first number of time-domain units compared to the second resource 362 in the frequency domain, so that the first resource 360 ​​and the third resource do not overlap.

[0148] In summary, the method provided in this embodiment is used to redetermine a third resource when the first resource 360 ​​and the second resource 362 partially or completely overlap. The third resource and the second resource 362 are advanced or delayed by a first number of time domain units in the time domain, and / or offset by a second number of frequency domain units in the frequency domain, so as to give priority to ensuring the reception or interference measurement of the downlink channel.

[0149] In some embodiments, the terminal device performs interference measurements on several interference measurement resources. After performing the interference measurements, the terminal device reports an interference measurement report to the network device. Depending on the configured reporting content, there may be three different reporting scenarios. For example, FIG15 shows a time-frequency resource diagram of interference measurement resources provided in an exemplary embodiment of this application. As shown in FIG15, for example, there are six interference measurement resources: interference measurement resource 151, interference measurement resource 152, interference measurement resource 153, interference measurement resource 154, interference measurement resource 155, and interference measurement resource 156. Wherein, if the interference measurement resource overlaps with the first resource, the interference measurement resource is a second resource. For example, interference measurement resources 152, 154, and 155 in FIG15 are all second resources.

[0150] Reporting Scenario 1: Reporting the measurement results of N interfering measurement resources

[0151] In some embodiments, the terminal device needs to report the measurement results of the largest N interference measurement resources. In other embodiments, the terminal device needs to report the measurement results of the smallest N interference measurement resources. In an optional embodiment based on the above embodiments, the terminal device is configured to report the measurement results of N interference measurement resources. The measurement results of the N interference measurement resources are a subset of the measurement results of the plurality of interference measurement resources. N is a positive integer. Optionally, the terminal device may use any one of the following three reporting methods: Reporting method 1-1: When it is necessary to report the measurement results of N interference measurement resources, the measurement results of the second resource are not reported. Optionally, the second resource is one or more of the plurality of interference measurement resources. For example, as shown in FIG15, in some embodiments, when it is necessary to report the measurement results of N interference measurement resources, the terminal device is configured to: not report the results of the second resource 152, the second resource 154 and the second resource 155. Reporting Method 1-2: When it is necessary to report the measurement results of N interference measurement resources, the measurement results of interference measurement resources other than the second resource are reported first. Optionally, the second resource is one or more of the several interference measurement resources. For example, as shown in FIG15, in some embodiments, when it is necessary to report the measurement results of N interference measurement resources, the terminal device is configured to: report the interference measurement resources other than the second resource first, i.e., the results of interference measurement resources 151, 153, and 156. Reporting Method 1-3: When it is necessary to report the measurement results of N interference measurement resources, the measurement results of the second resource are reported first. The measurement results of the second resource are represented by invalid values ​​or conflict indicators. For example, as shown in FIG15, in some embodiments, the terminal device is configured to report the results of the second resource 152 first, and the results of the second resource 154 and the second resource 155 are represented by invalid values ​​or conflict indicators. Optionally, the second resource is one or more of the several interference measurement resources.

[0152] In summary, the method provided in this embodiment, when it is necessary to report the resource results of N interference measurement resources, is not affected by the second resource that overlaps with the first resource 360 ​​in whole or in part, thus prioritizing the accuracy of the measurement results of the N interference measurement resources.

[0153] Reporting Scenario 2: Reporting the measurement results of the first interference measurement resource, where the first interference measurement resource is the second resource.

[0154] In some embodiments, the terminal device is configured to report the measurement results of a first interference measurement resource, where the first interference measurement resource is a second resource. The second resource 362 is one or more of a plurality of interference measurement resources, and the first interference measurement resource is the interference measurement resource closest to the first time-domain resource in the time domain dimension. The first time-domain resource includes the time-domain unit corresponding to the interference measurement report, or a time limit defined by a communication protocol. For example, FIG16 shows a time-frequency resource diagram of interference measurement resources provided in an exemplary embodiment of this application. As shown in FIG16, in some embodiments, the measurement results of the interference measurement resource closest to the first time-domain resource are calculated from right to left starting from the first time-domain resource. For example, the interference measurement resource closest to the first time-domain resource is interference measurement resource 156. The second resource includes interference measurement resources 152, 154, and 155.

[0155] Optionally, the terminal device may employ either of the following two reporting methods: Reporting Method 2-1: When it is necessary to report the measurement results of the first interference measurement resource and the first interference measurement resource is the second resource, the measurement results of the second resource are not reported; for example, as shown in Figure 16, the interference measurement resource closest to the first time domain resource is interference measurement resource 156, and the measurement results of the second resources 152, 154, and 155 are not reported. Reporting Method 2-2: When it is necessary to report the measurement results of the first interference measurement resource and the first interference measurement resource is the second resource, the measurement results of the second resource are reported, and the measurement results of the second resource are represented by invalid values ​​or conflict indications; for example, as shown in Figure 16, optionally, the measurement results of the second resources 152, 154, and 155 are reported as invalid values ​​or conflict indications.

[0156] In summary, the method provided in this embodiment, when it is necessary to report the measurement results of the first interference measurement resource and the first interference measurement resource is the second resource, is not affected by the second resource 362 that partially or completely overlaps with the first resource 360, thus prioritizing the accuracy of the measurement results of the interference measurement resource.

[0157] Reporting Scenario 3: Report the average value of measurement results from M interfering measurement resources.

[0158] In an optional embodiment based on the above embodiments, the terminal device is configured to, when it is necessary to report the average value of the measurement results of M interference measurement resources, including the second resource, the second resource is designated as an unavailable resource; or, the average value is determined based on the measurement result of at least one interference measurement resource other than the second resource among the M interference measurements; wherein the second resource is one or more of the M interference measurement resources. Where M is a positive integer.

[0159] In some embodiments, when it is necessary to report the average value of the measurement results of M interference measurement resources, the second resource is designated as an unavailable resource. For example, as shown in FIG15, when it is necessary to report the average value of the measurement results of M interference measurement resources, the second resource 152, the second resource 154 and the second resource 155 are designated as unavailable resources.

[0160] In some embodiments, when it is necessary to report the average value of the measurement results of M interference measurement resources, the average value is determined based on the measurement results of at least one interference measurement resource other than the second resource among the M interference measurements. The measurement results of the second resource are not included in the calculation of the average value. For example, as shown in FIG15, the measurement results of the second resources 152, 154 and 155 are not included in the calculation of the average value; only the average value of the interference measurement resources 151, 153 and 156 is calculated.

[0161] In summary, the method provided in this embodiment calculates the average value of the measurement results of M interfering measurement resources, excludes the second resource that partially or completely overlaps with the first resource, and prioritizes ensuring the accuracy of the measurement results of the interfering measurement resources.

[0162] Figure 17 illustrates a flowchart of a downlink channel transmission method provided in an exemplary embodiment of this application. The method is performed by a network device and includes:

[0163] Step 1702: If the first resource and the second resource overlap, execute the second action;

[0164] The first resource is used to carry the first downlink channel. The second resource is used for interference measurement. For a detailed description of the first resource, the second resource, and the first downlink channel, please refer to the relevant description in step 402 of the above embodiment; it will not be repeated here.

[0165] Overlap of the first and second resources: Overlap includes complete overlap or partial overlap. Complete overlap means that the first and second resources are the same size and also completely identical in position. For example, Figure 5 shows a schematic diagram of complete overlap of the first resource 360 ​​and the second resource 362 provided in an exemplary embodiment of this application.

[0166] Optionally, partial overlap includes at least one or more of the following three cases: First case: All resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362, as shown in Figure 6. Second case: A portion of the resources of the first resource 360 ​​overlaps with all resources of the second resource 362, as shown in Figure 7. Third case: A portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362, as shown in Figure 8.

[0167] The second action is used to resolve conflicts when the first and second resources overlap. In some embodiments, the second action prioritizes downlink transmission of the first downlink channel. In some embodiments, the second action prioritizes ensuring the accuracy of interference measurements. In some embodiments, the second action ensures that downlink transmission of the first downlink channel and interference measurements are performed simultaneously without interference.

[0168] Optionally, the second action includes one or more of the following four actions: Action 7: transmitting the first downlink channel in all or part of the resources of the first resource; Action 8: canceling the transmission of the first downlink channel in all or part of the resources of the first resource; Action 9: disabling interference measurement in all or part of the resources of the second resource; Action 10: re-determining a third resource for interference measurement, wherein the third resource is offset from the second resource in the time domain by a first number of time domain units, and / or offset from the second resource in the frequency domain by a second number of frequency domain units; wherein the first number and the second number are positive integers. The first number and / or the second number are agreed upon by the communication protocol or configured by the second information.

[0169] In summary, the method provided in this embodiment is used to perform a second action when the first resource and the second resource overlap, in order to resolve the conflict between downlink transmission and interference measurement, thereby prioritizing the transmission of the first downlink channel and / or prioritizing correct interference measurement.

[0170] For behavior seven: The network device transmits the first downlink channel in all or part of the resources of the first resource. In this case, the part of the resources of the first resource does not overlap with the second resource, or the part of the resources of the first resource does not include the second resource.

[0171] For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the first downlink channel is transmitted in all resources of the first resource 360. For example, as shown in FIG7, a portion of the resources of the first resource 360 ​​overlaps with all resources of the second resource 362. The first downlink channel is transmitted in the portion of the first resource 360 ​​that does not include the second resource 362. For example, as shown in FIG8, all resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362. The first downlink channel is transmitted in the portion of the first resource 360 ​​that does not overlap with the second resource 362.

[0172] For example, FIG9 illustrates a time-frequency resource diagram of a first resource 360 ​​and a second resource 362 provided in an exemplary embodiment of this application. As shown in FIG9, the PDSCH is a portion of the resources in the first resource 360, and the RB-level CLI-RSSI resource is the second resource 362, which occupies a plurality of consecutive RBs on a plurality of consecutive symbols. As shown in FIG10, the RE-level CLI-RSSI resource is the second resource 362, which occupies a plurality of discrete REs on a single symbol. The network device can implement the transmission of the first downlink channel on the portion of the resources excluding the second resource 362, i.e., the portion of the resources in the first resource 360. For example, in some embodiments, the portion of the resources excluding the second resource 362 may refer to the PDSCH resource excluding the RB-level CLI-RSSI resource. In some embodiments, the portion of the resources excluding the second resource 362 may refer to the PDSCH resource excluding the RE-level CLI-RSSI resource.

[0173] In some embodiments, the second resource 362 is configured by first information, and a portion of the resources of the first resource 360 ​​does not include all the resources configured by the first information. Optionally, the first information is higher-layer signaling or downlink control signaling, used to indicate the time-domain and / or frequency-domain configuration of the second resource 362. Optionally, a portion of the resources of the first resource 360 ​​refers to a portion of the resources that do not overlap with the second resource 362 and are used to carry the first downlink channel. The portion of the resources of the first resource 360 ​​does not include all the resources configured by the first information, that is, this portion of the resources does not include all symbols and all subcarriers configured by the first information.

[0174] In some embodiments, a portion of the resources of the first resource 360 ​​does not include the overlapping portion of the second resource 362 and the fourth resource, where the fourth resource is a zero-power signal recourse. The fourth resource is configured by higher-layer signaling or downlink control signaling. In some embodiments, the non-overlapping portions of the second resource 362 and the fourth resource support the transmission of the first downlink channel. For example, FIG11 shows a time-frequency resource diagram of the first and second resources provided in an exemplary embodiment of this application. As shown in FIG11, the second resource 362 is configured on PRB n to PRB m of symbol 1. The second resource 362 and the fourth resource overlap on a portion of the REs of PRB n and PRB m. The overlapping REs are treated as unavailable resources, and the first downlink channel is transmitted at locations where unavailable resources are not included. Optionally, in some embodiments, the REs occupied by the fourth resource in PRB n to PRB m are treated as unavailable resources, and the first downlink channel (e.g., PDSCH) is transmitted at other locations where unavailable resources are not included. Optionally, all fourth resources on symbol 1 are treated as unavailable resources, and the first downlink channel is transmitted at other locations where unavailable resources are not included. Optionally, in some embodiments, if the second resource overlaps with the fourth resource, all of the fourth resources are treated as unavailable resources, and the first downlink channel is transmitted at other locations that do not contain unavailable resources.

[0175] In summary, the method provided in this embodiment transmits the first downlink channel in all or part of the resources of the first resource where the first resource 360 ​​and the second resource 362 do not overlap, thus prioritizing the reception of the first downlink channel.

[0176] For behavior eight: The network device cancels the transmission of the first downlink channel in all or part of the first resource.

[0177] In some embodiments, the network device cancels the transmission of the first downlink channel on all resources of the first resource 360. For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the network device cancels the transmission of the first downlink channel on all resources of the first resource 360.

[0178] In some embodiments, the network device cancels transmission of the first downlink channel on a portion of the resources of the first resource 360. Optionally, the network device cancels transmission of the first downlink channel on a portion of the resources where the first resource and the second resource overlap. For example, as shown in FIG7, transmission of the first downlink channel is canceled on a portion of resource 364 where the first resource 360 ​​and the second resource 362 overlap. For example, as shown in FIG8, in some embodiments, a portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362, and transmission of the first downlink channel is canceled in the overlapping portion of the first resource 360 ​​and the second resource 362.

[0179] In summary, the method provided in this embodiment cancels the transmission of the first downlink channel on the first resource where the first resource 360 ​​and the second resource 362 overlap in whole or in part, thus prioritizing the accuracy of interference measurement.

[0180] For behavior nine: Network devices disable interference measurement on all or part of the second resource.

[0181] In some embodiments, the network device enables interference measurement on all resources of the second resource 362. For example, as shown in FIG5, all resources of the first resource 360 ​​overlap with all resources of the second resource 362. In some embodiments, the network device enables interference measurement on all resources of the second resource 362 and transmits a first downlink channel throughout the second resource 362. For example, as shown in FIG7, a portion of the resources of the first resource 360 ​​overlaps with all resources of the second resource 362. In some embodiments, the network device enables interference measurement on all resources of the second resource 362 and transmits a first downlink channel throughout the second resource 362.

[0182] In some embodiments, the network device enables interference measurement on a portion of the resources of the second resource 362. Optionally, the network device enables interference measurement on the portion where the second resource overlaps with the first resource. For example, as shown in FIG6, interference measurement is enabled on resource 364 where the first resource 360 ​​and the second resource 362 overlap. In some embodiments, the network device enables interference measurement on the overlapping portion of resource 364 and transmits a first downlink channel. For example, as shown in FIG8, in some embodiments, a portion of the resources of the first resource 360 ​​overlaps with a portion of the resources of the second resource 362. Interference measurement is enabled in the overlapping portion of the first resource 360 ​​and the second resource 362, and the network device transmits a first downlink channel on all resources of the first resource 360. In some embodiments, the network device prioritizes the transmission of the first downlink channel. For example, as shown in FIG14, the second resource 362 used for measuring interference overlaps with the first resource 360 ​​on PRB n to PRB m of symbol 1. In this case, the network device enables interference measurement on a portion of the resources of the second resource 362, that is, the network device enables interference measurement on the resource where the first resource 360 ​​and the second resource 362 partially overlap.

[0183] In summary, the method provided in this embodiment enables interference measurement on the second resource where the first resource 360 ​​and the second resource 362 overlap in whole or in part, thus prioritizing the transmission of the first downlink channel.

[0184] For behavior ten: A third resource is reassigned for interference measurement, the third resource being offset from the second resource in the time domain by a first number of time-domain units, and / or offset in the frequency domain by a second number of frequency-domain units; wherein the first and second numbers are positive integers. The first and / or second numbers are defined by the communication protocol or configured by second information. In some embodiments, the second information refers to signaling.

[0185] In summary, the method provided in this embodiment is used to redetermine a third resource for interference measurement when the first resource 360 ​​and the second resource 362 overlap completely or partially. The third resource and the second resource 362 are advanced or delayed by a first number of time domain units in the time domain, and / or offset by a second number of frequency domain units in the frequency domain, so that the first resource 360 ​​and the redetermined third resource do not overlap, thus prioritizing the transmission of the first downlink channel or interference measurement.

[0186] For example, as shown in Figure 6, all resources of the first resource 360 ​​overlap with a portion of the resources of the second resource 362. In some embodiments, a third resource that is advanced or delayed by a first number of time-domain units from the second resource 362 in the time domain is determined as a new resource for interference measurement, such that the first resource 360 ​​does not overlap with the newly determined interference measurement resource, i.e., the third resource. In other embodiments, a third resource that is offset by a second number of frequency-domain units from the second resource 362 in the frequency domain is determined as a new resource for interference measurement, such that the first resource 360 ​​does not overlap with the newly determined interference measurement resource.

[0187] Figure 18 illustrates a flowchart of a resource determination method provided in an exemplary embodiment of this application. The method is executed by a terminal device and includes:

[0188] Step 1802: Do not expect the first resource to overlap with the second resource;

[0189] The first resource is used to carry the first downlink channel, and the second resource is used for interference measurement. The terminal equipment does not expect the first and second resources to overlap. This can also be understood as the terminal equipment expecting the first and second resources not to overlap. Not expecting the first and second resources to overlap includes one or more of the following: Case 1: Not expecting the first and second resources to overlap in the time domain; Case 2: Not expecting the first and second resources to overlap in the frequency domain; Case 3: Not expecting simultaneous downlink reception and interference measurement; Case 4: Expecting the first and second resources to be at least Z time slots or symbols apart in the time domain.

[0190] In summary, the method provided in this embodiment is intended to ensure that the first resource and the second resource do not overlap, thereby guaranteeing resource determination.

[0191] Regarding scenario one: The terminal device does not expect the first resource and the second resource to overlap in the time domain. In some embodiments, the terminal device expects the first resource and the second resource to be completely non-overlapping in the time domain.

[0192] Regarding scenario two: The terminal device does not expect the first resource and the second resource to overlap in the frequency domain. In some embodiments, the terminal device expects the first resource and the second resource to be completely non-overlapping in the frequency domain. For example, FIG12 shows a time-frequency resource diagram of the first resource and the second resource provided in an exemplary embodiment of this application. As shown in FIG12, in some embodiments, the first resource 360 ​​occupies a portion of the resources on PRB n to PRB m, and the second resource 362 occupies a portion of the resources on PRB k to PRB l. In this case, the first resource 360 ​​and the second resource 362 are completely non-overlapping in the frequency domain.

[0193] For scenario three: The terminal device does not expect to perform downlink reception and interference measurement simultaneously. The terminal device does not expect to perform downlink reception and interference measurement simultaneously on the same resources. In some embodiments, downlink reception has higher priority than interference measurement; in this case, the terminal device prioritizes downlink reception. In some embodiments, interference measurement has higher priority than downlink reception; in this case, the terminal device prioritizes interference measurement.

[0194] Regarding scenario four: The terminal device expects the first resource and the second resource to be at least Z time slots or symbols apart in the time domain. Figure 13 shows a time-frequency resource diagram of the first resource and the second resource provided in an exemplary embodiment of this application. As shown in Figure 13, the first resource occupies part of the resources of symbols 2 to 4, and the second resource occupies part of the resources of symbol 1. In this case, the first resource and the second resource are at least one symbol apart in the time domain, which can ensure that downlink reception and interference measurement are spaced apart in the time domain, avoiding the reception of useful signals in the downlink channel from affecting interference measurement. In some embodiments, the terminal device expects the first resource 360 ​​and the second resource 362 to differ by at least Z time slots or symbols, so that the first resource 360 ​​and the second resource 362 do not overlap in the time domain. For example, as shown in Figure 13, in some embodiments, the first resource 360 ​​occupies part of the resources of symbols 2 to 4, and the second resource 362 occupies part of the resources of symbol 1. In this case, the first resource 360 ​​and the second resource 362 do not overlap at all in the time domain.

[0195] Network devices may consider or ignore the expectations or non-expectations of terminal devices. Even when a network device ignores the expectations or non-expectations of a terminal device, the network device may still configure the first resource and the second resource to overlap. In some embodiments, if the first resource 360 ​​and the second resource 362 overlap, the terminal device redetermines a third resource for interference measurement. The third resource is offset from the second resource 362 in the time domain by a first number of time-domain units, and / or offset in the frequency domain by a second number of frequency-domain units, such that the first resource 360 ​​and the redetermined interference measurement resource do not overlap. Here, both the first and second numbers are positive integers.

[0196] In some embodiments, the first quantity and / or the second quantity are agreed upon by the communication protocol or configured by the second information. In some embodiments, the second resource 362 is configured by the first information. When the terminal device determines that the first resource 360 ​​and the second resource 362 overlap completely or partially, a third resource for interference measurement is re-determined. The third resource is advanced or delayed by a first number of time-domain units in the time domain and / or offset by a second number of frequency-domain units in the frequency domain, so that the first resource 360 ​​and the re-determined third resource do not overlap, thus prioritizing the transmission of the first downlink channel or interference measurement.
