Description

Interference measurement method, device, chip module and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a chip module, and a storage medium for interference measurement.

Background

With the rapid increase of uplink traffic demand, higher demands are put forward on uplink coverage, rate and time. The full duplex technology can simultaneously transmit uplink and downlink at the same time, and provides opportunities for enhancing uplink services compared with the existing time division duplex (time division duplex, TDD) system which is more focused on downlink transmission. As a third generation partnership project (3 ^rd generation partnership project,3 GPP) release 18 (R18), the duplex enhancement issue will be studied for sub-band full duplex at the base station side. As shown in fig. 1a to 1d, on the base station side, uplink and downlink transmission is divided in the frequency domain by using the existence of sub-bands, so that interference is reduced by using frequency division while uplink and downlink transmission can be performed at the same time, complexity of the base station is reduced, and the base station is easier to realize and becomes a standardized hotspot. Where t represents time, f represents frequency, D represents downlink (downlink), and U represents uplink (uplink).

For sub-band full duplex, the base station side divides the frequency domain resource into different sub-bands, and at the same time, the different sub-bands can respectively perform downlink transmission and uplink reception. For a User Equipment (UE), half duplex is still supported, and only downlink reception can be performed in a downlink sub-band or uplink transmission can be performed in an uplink sub-band at a certain point in time. This introduces inter-subband cross-link interference (UE-to-UE inter subband CLI) between the user equipment and intra-subband cross-link interference (UE-to-UE intra subband CLI) of the user equipment.

In sub-band full duplex, there is currently no relevant technology to implement how a terminal device subject to cross-link interference (cross link interference, CLI) measures cross-link interference.

The embodiment of the application provides an interference measurement scheme, wherein a first terminal device subjected to cross-link interference receives configuration information for configuring measurement resources to perform cross-link interference measurement on the corresponding measurement resources, so that a method for measuring cross-link interference in a sub-band full duplex scene is provided.

The method for interference measurement provided in the embodiments of the present application is specifically described below.

Fig. 5 is a schematic flow chart of a method for interference measurement according to an embodiment of the present application. Illustratively, the method may include the steps of:

s501, the network equipment sends configuration information.

Accordingly, the first terminal device receives the configuration information.

In order to acquire the cross-link interference suffered by the first terminal device, the network device needs to configure measurement resources for the first terminal device to measure the cross-link interference. Specifically, the network device sends configuration information to the first terminal device.

Wherein the configuration information is used to configure the measurement resources. The measurement resources are used to measure cross-link interference. In one case, the measurement resources include resources in BWP, and/or in another case, the measurement resources include at least one of the following resources: resources in the downlink frequency domain resources, resources in guard band (guard band), RSSI-resource.

The downlink frequency domain resource is a continuous frequency domain resource, for example, a continuous Resource Block (RB) or a subcarrier, which is a frequency domain resource only used for downlink transmission, and may be a downlink subband in full duplex of subbands.

In the full duplex scene of the sub-band, because uplink and downlink transmission can be performed at the same time, the uplink and downlink transmission is divided by different frequency domain resources, in order to reduce uplink and downlink interference, a section of frequency domain resource is inserted between the uplink and downlink frequency domain resources, and uplink and downlink transmission cannot be performed on the section of frequency domain resource, and the section of frequency domain resource may be called a guard band.

The cross-link interference includes interference of uplink transmission of the second terminal equipment on the second time-frequency resource to downlink reception of the first terminal equipment on the first time-frequency resource. The time domain resources of the first time-frequency resource and the second time-frequency resource are the same.

Or, the cross-link interference includes interference of uplink transmission of the plurality of second terminal devices on the plurality of second time-frequency resources (one second terminal device corresponds to one second time-frequency resource) on downlink reception of the first terminal device on the first time-frequency resource. The first time-frequency resource and the time-domain resources of the plurality of second time-frequency resources are the same. The present embodiment does not limit the number of second terminal apparatuses.

Or, the cross-link interference includes interference that the uplink transmission of the second terminal device on the second time-frequency resource receives downlink from the plurality of first terminal devices on the plurality of first time-frequency resources (one first terminal device corresponds to one first time-frequency resource). The time domain resources of the plurality of first time-frequency resources and the second time-frequency resources are the same. The present embodiment does not limit the number of first terminal apparatuses. The first terminal device described in step S501 is any one of the plurality of first terminal devices, and the cross-link interference measured by the first terminal device described in step S501 refers to interference that uplink transmission of the second terminal device on the second time-frequency resource receives downlink of the first terminal device on the corresponding first time-frequency resource.

Or, the cross-link interference includes interference that uplink transmission of the plurality of second terminal devices on the plurality of second time-frequency resources (one second terminal device corresponds to one second time-frequency resource) receives downlink of the plurality of first terminal devices on the plurality of first time-frequency resources (one first terminal device corresponds to one first time-frequency resource). The time domain resources of the plurality of first time-frequency resources and the plurality of second time-frequency resources are the same. The number of the first terminal device and the second terminal device is not limited in this embodiment, and may be one or more. The first terminal device described in step S501 is any one of the plurality of first terminal devices, and the cross-link interference measured by the first terminal device described in step S501 refers to interference that uplink transmissions of the plurality of second terminal devices on the plurality of second time-frequency resources receive downlink signals of the first terminal device on the corresponding first time-frequency resources.

Wherein the frequency domain resources of the first time-frequency resource (which may be referred to as first frequency domain resources) and the frequency domain resources of the second time-frequency resource (which may be referred to as second frequency domain resources) may be completely different, or partially identical, or completely identical. The first frequency domain resource and the second frequency domain resource are each a segment of contiguous frequency domain resource. The first frequency domain resource and the second frequency domain resource may be located in the same BWP or may be located in different BWP.

In the case where the first frequency domain resource and the second frequency domain resource are completely different, the first frequency domain resource and the second frequency domain resource may be different subbands in a subband full duplex scenario. For example, the first frequency domain resource may be a downlink subband in a subband full duplex scenario, and the second frequency domain resource may be an uplink subband in a subband full duplex scenario, where the two subbands may be adjacent subbands or non-adjacent subbands. Each subband may be a segment of contiguous frequency domain resources. The division of the subbands in the subband full duplex scenario and/or the direction of transmission (upstream or downstream) on each subband may be configured for the network device, or protocol-specified, or otherwise determined, without limitation.

As shown in fig. 6, an interference measurement scenario is illustrated in an example of the present application, where an interfering terminal device (UE 1, i.e. a second terminal device) uses a transmission beam to be measured to transmit an uplink signal (e.g. a sounding reference signal (sounding reference signal, SRS)) on an uplink frequency domain resource (i.e. a frequency domain resource of a second time-frequency resource), and other interfered terminal devices (victim UEs) (UE 2, UE3, i.e. a first terminal device) receive a downlink signal on a downlink frequency domain resource (i.e. a frequency domain resource of a first time-frequency resource), and perform measurement and reporting of cross-link interference on a measurement resource.

The present embodiment relates to configuration of cross-link measurement resources and configuration of reporting content.

For example, the measurement resources configured in the present application are zero power channel state information reference signal (ZP-CSI-RS) resources, that is, the network device does not send a signal on the resources, and the first terminal device performs cross-link interference measurement on all the configured measurement resources, where the obtained signal strength is the interference signal strength.

Illustratively, the configuration of measurement resources in this embodiment may include the following cases:

Case 1, the measurement resources include resources in the downlink frequency domain resources.

At this time, the following 3 implementations are possible:

in mode 1.1, the configuration information includes a first index, where the first index is used to indicate downlink frequency domain resources. The downlink frequency domain resource includes one or more resource blocks. In this implementation, the network device is configured to instruct the first terminal device to perform CLI measurement on all resource blocks in the downlink frequency domain resource corresponding to the first index through the configuration information. For example, in one BWP, the downlink frequency domain resource has a unique index, and the downlink frequency domain resource can be uniquely distinguished by the index. The network device sends a first index i to indicate a downlink frequency domain resource with index i, where the value of i may be 0,1,2, …. And the first terminal equipment performs CLI measurement on the downlink frequency domain resource i. As shown in fig. 7, a schematic diagram of a measurement resource configuration is shown in an example of the embodiment of the present application, where a first index is 1, and the first index is used to indicate downlink frequency domain resource 1. The first terminal device performs cross-link interference measurement on all resource blocks of the downlink frequency domain resource 1. For example, the configuration information may also include indexes of a plurality of downlink frequency domain resources, and the first terminal device performs cross-link interference measurement on all resource blocks of the plurality of downlink frequency domain resources.

Mode 1.2, the configuration information includes one or more of the following information: the first index, the index of the first resource block and the number of the first resource blocks. In this implementation, the network device is configured to instruct, through the configuration information, the first terminal device to perform CLI measurement on some or all resource blocks in the downlink frequency domain resource corresponding to the first index. For example, the first index i is used to indicate the downlink frequency domain resource with index i, the index j of the first resource block is used to indicate the start resource block j of the measurement resource in the downlink frequency domain resource i, and the first number of resource blocks is used to indicate the number of resource blocks of the measurement resource in the downlink frequency domain resource. Wherein the values of i and j can be 0,1,2 and … respectively. Assuming that the downlink frequency domain resource i includes 10 resource blocks, the value of j may be any value from 0 to 9. As shown in fig. 8, in another measurement resource configuration diagram of an example of the embodiment of the present application, the first index is 1, the index of the first resource block is 2, and the number of the first resource blocks is 3, and then the first terminal device performs the inter-link interference measurement on the resource blocks 2, 3, and 4 (i.e., RB2 to RB4 in fig. 8) of the downlink frequency domain resource 1. It should be noted that, the indexes of the resource blocks in the drawings of the present application are merely examples, and in actual implementation, indexes of resource blocks in different frequency domain resources may be numbered together, and in this case, the index of the first resource block of the downlink frequency domain resource 1 may not be 0.

It should be noted that, in the embodiment 1.2, if the configuration information includes only the first index, the index of the first resource block, and part of the information in the number of the first resource blocks, other information may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device, which is not limited in this application. For example, if the configuration information includes only the first index, the index of the first resource block, the first number of resource blocks may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device. The first index, the index of the first resource block, and the number of the first resource blocks may be configured by one piece of configuration information, or may be configured by multiple pieces of configuration information. The configuration information in this embodiment is a generic term.

In this implementation, the network device is configured to instruct the first terminal device to perform CLI measurement on some or all of the downlink frequency domain resources of the first index through the configuration information. For example, the first index i is used to indicate downlink frequency domain resources with index i, and the first bitmap is used to indicate continuous or discontinuous measurement resources in the downlink frequency domain resources. Wherein i can be 0,1,2, …. As shown in fig. 9, a schematic diagram of another measurement resource configuration of an example of the embodiment of the present application is shown in fig. 9, where a first index is 1, and the first index is used to indicate downlink frequency domain resource 1. The downlink frequency domain resource 1 includes 10 resource blocks, assuming that the first bitmap is 0001000100, a bit corresponds to a resource block in the downlink frequency domain resource 1, and assuming that a value of a bit is 1, which indicates that the resource block corresponding to the bit is a measurement resource, the first terminal device measures the cross-link interference on the resource block 3 and the resource block 7 of the downlink frequency domain resource 1 (e.g., the black filled resource block in fig. 9).

Alternatively, one bit in the first bitmap may be used to represent a plurality of RBs, and the present embodiment does not limit how many RBs one bit represents. For example, 10 RBs of downlink frequency domain resource 1 may be indicated with a 5-bit bitmap, with 1 bit representing 2 RBs. Assuming that the first bitmap is 00101, the first terminal device measures cross-link interference on resource blocks 4, 5, 8, 9 (i.e., RB4, RB5, RB8, and RB 9) of downlink frequency domain resource 1.

It should be noted that, in the embodiment 1.3, if the configuration information includes only the first index and part of the information in the first bitmap, other information may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device, which is not limited in this application.

The second index is used for indicating the guard band, the index of the second resource block is used for indicating the initial resource block of the measurement resource in the guard band, and the number of the second resource blocks is used for indicating the number of the resource blocks of the measurement resource in the guard band. There may be multiple guard bands in the configured BWP, one for each index. The guard band includes a plurality of resource blocks, each resource block having a corresponding unique index. The first terminal device starts to perform cross-link interference measurement on the initial resource block indicated by the index of the second resource block in the guard band, and performs cross-link interference measurement on the resource block of the second number of resource blocks starting from the initial resource block indicated by the index of the second resource block.

It should be noted that, in the embodiment 2.2, if the configuration information includes only the second index, the index of the second resource block, and part of the information in the number of the second resource blocks, other information may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device, which is not limited in this application. For example, if the configuration information includes only the second index, the index of the second resource block, the second number of resource blocks may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device. The second index, the index of the second resource block, and the number of the second resource blocks may be configured by one piece of configuration information, or may be configured by multiple pieces of configuration information. The configuration information in this embodiment is a generic term.

Mode 2.3, wherein the configuration information includes at least one of: a second index, a second bitmap. In this implementation, the network device is configured to instruct the first terminal device to perform CLI measurement on some or all resources in the guard band corresponding to the second index through the configuration information. Wherein the second index is used to indicate guard bands and the second bitmap is used to indicate measurement resources in the guard bands.

The second index may be used to indicate a guard band as a measurement resource. The second bitmap may be used to indicate one or more resource blocks in the guard band as measurement resources.

It should be noted that, in the mode 2.3, if the configuration information includes only the second index and part of the information in the second bitmap, other information may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device, which is not limited in this application. For example, if the configuration information includes only the second bitmap, the second index may be preconfigured, or protocol-specified, or the network device and the terminal device may negotiate a determination. The second index and the second bitmap may be configured by one piece of configuration information, or may be configured by a plurality of pieces of configuration information. The configuration information in this embodiment is a generic term.

Case 3, measurement resources include resources in BWP

At this time, there may be the following 2 implementations:

mode 3.1, wherein the configuration information includes at least one of: the third index, the index of the third resource block and the number of the third resource blocks. Wherein the third index is used to indicate BWP. In this implementation, the network device is configured to instruct the first terminal device to perform CLI measurement on some or all of the resources in the BWP through the configuration information. Wherein the index of the third resource block is used for indicating the initial resource block of the measurement resource in the BWP, and the third resource block number is used for indicating the resource block number of the measurement resource in the BWP. The BWP comprises a plurality of resource blocks, each resource block having a corresponding unique index. The first terminal device starts the inter-link interference measurement on the starting resource block indicated by the index of the third resource block in the BWP, and performs the inter-link interference measurement on the resource block of the third number of resource blocks starting from the starting resource block indicated by the index of the third resource block.

It should be noted that, in the embodiment 3.1, if the configuration information includes only the third index, the index of the third resource block, and part of the information in the number of the third resource blocks, other information may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device, which is not limited in this application. For example, if the configuration information includes only the third index, the index of the third resource block, the third number of resource blocks may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device. The third index, the index of the third resource block, and the number of the third resource blocks may be configured by one piece of configuration information, or may be configured by multiple pieces of configuration information. The configuration information in this embodiment is a generic term.

Mode 3.2, wherein the configuration information includes at least one of: third index, third bitmap. In this implementation, the network device is configured to instruct the first terminal device to perform CLI measurement on some or all of the resources in the BWP through the configuration information. Wherein the third bitmap is used to indicate measurement resources in BWP. The BWP comprises a plurality of resource blocks, each resource block having a corresponding unique index. The third bitmap may indicate consecutive or non-consecutive several resource blocks in BWP as measurement resources.

It should be noted that, in the embodiment 3.2, if the configuration information includes only the third index and part of the information in the third bitmap, other information may be preconfigured, or specified by a protocol, or determined by negotiation between the network device and the terminal device, which is not limited in this application. For example, if the configuration information includes only the third bitmap, the third index may be preconfigured, or protocol-specified, or the network device and the terminal device may negotiate a determination. The third index and the third bitmap may be configured by one piece of configuration information, or may be configured by a plurality of pieces of configuration information. The configuration information in this embodiment is a generic term.

Case 4, measurement resources include RSSI-resource

At this time, there may be the following 1 implementation:

mode 4.1, the configuration information includes: index of RSSI-resource. The network device may be preconfigured with one or more RSSI-resources, each having a corresponding unique index. The network device can configure the index of the RSSI-resource through the configuration information, and the first terminal device can perform cross-link interference measurement on the RSSI-resource corresponding to the index of the RSSI-resource according to the configuration information.

The various implementations of the above cases 1, 2, and 3 may be combined with each other. For example, one resource in BWP is configured in mode 3.1, and another resource is configured in mode 1.3, and measurements are performed on both resources at the same time. In the current protocol, measurement for CLI is based on a period, and measurement is performed on the configured measurement resources by configuring the periodic measurement resources through radio resource control (radio resource control, RRC) signaling. These resource configurations are periodic, and such configurations are inflexible and may result in wasted resources and may also result in inaccurate measurements. In this embodiment, the configuration information may be carried in MAC-CE and/or DCI, so that dynamic configuration may be implemented, which is more accurate and flexible than the existing configuration in which measurement resources are periodically configured through radio resource control (radio resource control, RRC). Specifically, the periodic measurement resources do not consider the actual measurement requirements, and in the full duplex of the sub-bands, the configuration of the sub-bands may be dynamically changed, so that the measurement resources required by different times are different. For example, in the embodiment of the present application, the CLI may be interference of the uplink subband signal to the downlink subband signal, and due to different scheduling, the same UE may need to measure the interfered condition on different resources at different times, and by dynamically configuring the measurement resources, the interference measurement can be flexibly and accurately performed.

S502, the first terminal equipment measures cross-link interference on measurement resources.

The network equipment sends a reference signal on the configured measurement resource, and the first terminal equipment measures the reference signal on the measurement resource to obtain a measurement result of cross-link interference.

For example, the value of the measurement result reported by the cross-link interference may be the value of RSSI. Further, the method may further comprise the following steps (indicated by dotted lines):

s503, the first terminal equipment reports the measurement result of the cross-link interference, and the measurement result of the cross-link interference is only processed through a physical layer in the first terminal equipment.

Accordingly, the network device receives the measurement of the cross-link interference.

The existing CLI reporting mechanism is based on layer3 (L3). In this embodiment, the measurement result of the cross-link interference may be processed only by the physical layer (i.e., layer1, L1) in the first terminal device. Therefore, the measurement result is directly reported through the L1 without passing through an L3 filter, so that the timeliness of reporting the measurement result can be improved, and the reporting time delay is reduced.

In addition, for the full duplex scenario of the sub-band, the transmission resources and the measurement resources are not necessarily the same, that is, the measurement resources may not overlap with the interference transmission resources, and the signal power measured on the measurement resources is smaller than the original L3CLI-RSSI value, so that the existing reporting content range cannot be used. Accordingly, the range and granularity of the L1-CLI-RSSI need to be redefined. Compared with the L3 CLI-RSSI-Range-r16 ranging from-100 dBm to-25 dBm, the granularity is 1dB, the lower limit of the measurement result reported by the redefined cross-link interference in the embodiment is lower than-100 dBm, namely the value of the RSSI can be smaller than-100 dBm, so that the measurement result of the cross-link interference can be more accurately represented.

According to the method for measuring the interference, the first terminal equipment subjected to the cross-link interference receives the configuration information for configuring the measurement resources, and the cross-link interference measurement is carried out on the corresponding measurement resources, so that the method for measuring the cross-link interference in the sub-band full duplex scene is provided.

It should be noted that although the present application mainly solves the problem of cross-link interference measurement in a full-duplex sub-band scenario, the present application may also be applied to a scenario with similar requirements in a non-duplex sub-band scenario, and the present application is not limited.
