Time domain behavior and QCL relation for SINR measurement

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling that configures a channel measurement resource and an interference measurement resource within a same time interval. The UE may transmit a measurement report that indicates a signal to interference plus noise ratio (SINR) measurement that is generated based on measuring the channel measurement resource and the interference measurement resource. In some cases, the UE may receive a quasi co-location (QCL) relationship indicator that indicates a QCL relationship for the interference measurement resource or the channel measurement resource. The UE may measure the channel measurement resource and the interference measurement resource in accordance with the QCL relationship.

BACKGROUND

The following relates generally to wireless communications, and more specifically to time domain behavior and quasi co-location (QCL) relation for signal to interference plus noise ratio (SINR) measurement.

In some cases, a base station may transmit reference signals to a user equipment (UE) that may use the reference signals to perform channel estimation. Additionally, the base station and the UE may use beamforming to increase transmission directivity in a particular direction, which may increase communication reliability in that direction. Conventional techniques of performing channel estimation and beamforming may be deficient in at least some applications.

SUMMARY

The described techniques relate to improved methods, systems, devices, and apparatuses that support time domain behavior and quasi co-location (QCL) relation for signal to interference plus noise ratio (SINR) measurement. Generally, the described techniques provide for a user equipment (UE) to receive control signaling that configures a channel measurement resource (CMR) and an interference measurement resource (IMR) within a same time interval. The UE may transmit a measurement report that indicates a SINR measurement that is generated based on measuring the CMR and the IMR. A base station may receive the measurement report and may schedule communications to the UE, select a beam pair for use in communication via a wireless channel, or both.

In some cases, the UE may use a same beam to measure each of the CMR and the IMR to generate the L1-SINR measurement. To ensure that the L1-SINR measurement may be made using a single beam, a base station may choose a CMR and IMR that have a same QCL relationship and may transmit a QCL relationship indicator to the UE that indicates a QCL relationship for the IMR or the CMR. The UE may receive the QCL relationship indicator and may measure the CMR and the IMR in accordance with the QCL relationship.

DETAILED DESCRIPTION

A user equipment (UE) may determine a layer 1 signal to noise plus interference ratio (L1-SINR), which may involve the UE performing SINR measurements for transmissions from a base station over a short duration of time. The duration of time may be configured such that the interference term associated with the L1-SINR is not averaged over more than a threshold number of beams. Determining L1-SINR may involve the UE measuring a channel measurement resource (CMR) to determine a channel measurement and measuring an interference measurement resource (IMR) to determine an interference measurement. The time interval over which the CMR and IMR is being measured may be relatively short and may not be long enough for one or more interfering base stations to cycle through many downlink beams, and thus the interference measurement by the UE may not be an average of interference over transmission beams, receive beams, or both. To ensure that the UE measures CMRs and IMRs that are within a short enough duration of time, a base station may transmit to the UE a configuration for the CMR and IMR in which the CMR and IMR are within a same time interval. The SINR measurement may be over a short time interval so that the UE captures a current measurement of the channel. (e.g., an instantaneous observation of the wireless channel). The UE may generate and transmit a measurement report that indicates the SINR measurement, and the base station may use the indicated SINR for making communication determinations, such as scheduling communications to the UE and/or selecting a beam pair to use for communication via a wireless channel.

In some cases, the UE may use a same beam to measure each of the CMR and the IMR to generate the L1-SINR measurement. To ensure that the L1-SINR measurement may be made using a single beam, the base station may ensure that the CMR and IMR used for L1-SINR have a same QCL relationship that indicates to use a same beam for measuring each. The base station may do so by choosing CMRs and IMRs that already have the same QCL relationship or may override a configured QCL for the CMR or the IMR such that the CMR and IMR have the same QCL relationship. The UE may determine that the QCL relationship for the IMR is the same as that of the CMR.

Aspects of the disclosure are initially described in the context of a wireless communications system. Additional aspects of the disclosure are described in the context of an additional wireless communications system, a resource configuration, and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to time domain behavior and QCL relation for SINR measurement.

Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). A wireless network, for example a wireless local area network (WLAN), such as a Wi-Fi (i.e., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network may include an access point (AP) that may communicate with one or more wireless or mobile devices. The AP may be coupled to a network, such as the Internet, and may enable a mobile device to communicate via the network (or communicate with other devices coupled to the access point). A wireless device may communicate with a network device bi-directionally. For example, in a WLAN, a device may communicate with an associated AP via downlink (e.g., the communication link from the AP to the device) and uplink (e.g., the communication link from the device to the AP). A wireless personal area network (PAN), which may include a Bluetooth connection, may provide for short range wireless connections between two or more paired wireless devices. For example, wireless devices such as cellular phones may utilize wireless PAN communications to exchange information such as audio signals with wireless headsets.

Generally, the present disclosure may relate to time domain behavior and QCL relation for CMR and IMR for L1 SINR measurements. For instance, a UE115may receive control signaling that configures a CMR and an IMR within a same time interval. The UE115may transmit a measurement report that indicates a SINR measurement that is generated based on measuring the CMR and the IMR. In some cases, the UE115may receive a QCL relationship indicator that indicates a QCL relationship for the IMR or the CMR. The UE115may measure the CMR and the IMR in accordance with the QCL relationship.

FIG. 2illustrates an example of a wireless communications system200that supports time domain behavior and QCL relation for SINR measurement in accordance with aspects of the present disclosure. In some examples, wireless communications system200may implement aspects of wireless communications system100. For instance, UE115-amay be an example of a UE115as described with reference toFIG. 1and base station105-amay be an example of a base station105as described with reference toFIG. 1.

UEs115-aand115-bmay be within a coverage area110-aof base station105-a. Base station105-b, meanwhile, may be associated with a different coverage area110from base station105-a(e.g., coverage area110-b). Interference from base station105-bwith transmissions that occur within coverage area110-amay be referred to as inter-cellular interference. Interference from base station105-ato UE115-bor vice-versa with transmissions between UE115-aand base station105-amay be referred to as intra-cellular interference. Base station105-amay transmit signals to UEs115within coverage area110-avia transmit beams205(e.g., transmit beams205-a,205-b, and205-c). UE115-amay receive signals from base station105-avia receive beam210over communication link215.

In an example, base station105-amay transmit control signaling to UE115-a(e.g., via beam205-b) that configures one or more CMRs220and IMRs225. UE115-amay measure signals (e.g., reference signals230and235) transmitted by base station105-aover the configured CMRs220and IMRs225and may determine or calculate an L1-SINR. UE115-amay transmit a report back to base station105-athat indicates the determined or calculated L1-SINR.

An L1 SINR may be a SINR measurement over a short duration of time and may be used to approximate an instantaneous SINR measurement. The measurement may be short enough such that interfering base stations105(e.g., base station105-b) may cycle through fewer than a threshold number of downlink beams. As such, the interference term may not be a function of (e.g., averaged over) a large number of transmit beams and receive beams (e.g., more than a threshold number of beams).

In some cases, determining L1-SINR may enable more effective MU-MIMO scheduling. For instance, if L1-SINR is determined using transmit beam205-band receive beam210, L1-SINR may provide signal power and interfering power information for MU-MIMO when base station105-auses transmit beam205-band UE115-auses receive beam210to receive. The interference may be inter-cell interference from neighboring base stations105or gNBs (e.g., base station105-b) or may be intra-cell interference from base station105-afor another UE115(e.g., for UE115-b).

The L1-SINR may be made of a channel measurement resource and an interference measurement resource and may be denoted as CMR+IMR, where CMR may be the channel measurement at a CMR220and IMR may be the interference measurement at an IMR225. Measuring the CMR220may involve UE115-ameasuring a reference signal within the CMR220(e.g., a channel state information reference signal (CSI-RS)) transmitted by base station105-a. Measuring the IMR225, meanwhile, may involve UE115-ameasuring interference from a non-zero power (NZP) reference signal (e.g., CSI-RS) and/or a zero-power (ZP) reference signal (e.g., CSI-RS). If measuring interference from a NZP reference signal, base station105-amay transmit a reference signal (e.g., the NZP CSI-RS) in at least one resource element (RE) of the IMR225and UE115-amay measure the reference signal transmission from base station105-a. Upon measuring the NZP reference signal transmission, UE115-amay subtract the NZP reference signal transmission from the power measurement to determine interference. If measuring interference from a ZP reference signal, UE115-amay measure power in the RE of the ZP CSI-RS to determine interference.

For an L1-SINR measurement to enhance MU-MIMO scheduling (e.g., for L1-SINR measurement to be useful), CMR220and IMR225may be near each other in terms of time. For example, the CMR220and the IMR225may occur within a same time interval. In some examples, the time interval may be a slot, subframe, frame, or the like. In some examples, the CMR220and the IMR225may occur within overlapping symbol periods (e.g., OFDM symbol periods) of a slot (e.g., partially or completely overlap in time), may occur within adjacent sets of symbol periods, or the like. In some examples, CMR220and IMR225may be periodic with similar or same periodicity. In some examples, using a current measurement of CMR220with outdated measurement of IMR225to generate the SINR may fail to capture the relative instantaneousness associated with determining L1-SINR and may thus be avoided. To avoid this, the UE115-agenerating the SINR may measure a CMR220and an IMR225that both occur within a same time interval.

In an example, each or all channel state information (CSI) resource settings linked to a CSI report setting having a same time domain behavior for an L1-SINR report. In some examples, the base station105-amay transit control signaling to configure the UE115-awith a first CSI resource setting for the CMR220, and a second CSI resource setting for ZP or NZP-IMR. Having the same time domain behavior may involve an IMR225and a CMR220being within a same time interval or occurring within a number of symbol periods from each other. Having the same domain behavior may involve the IMR225and the CMR220overlapping in time (e.g., sharing time resources). In some examples, the IMR225and the CMR220may both occur within a same resource block, or may be in different, adjacent, resource blocks (RBs). In some examples, resources blocks that include CMR220may be interleaved with resource blocks that include IMR225. In an example, CMR220may be in a first CSI resource setting while ZP or NZP-IMR225may be in a second CSI resource setting.

When base station105-atransmits the control signaling to UE115-a, the control signaling may indicate that UE115-ais to transmit an aperiodic L1-SINR report, a semi-persistent L1-SINR report, or a periodic L1-SINR report. For an aperiodic L1-SINR report, common time domain behavior (e.g., that the CMR220and the IMR225occur in a same time interval) between the first and second CSI resource settings may be periodic, semi-persistent, or aperiodic. The time domain behavior being periodic or semi-persistent may involve UE115-ahaving been configured by the base station105-awith multiple instances of CMRs220and IMRs225that occur periodically or occur at defined time instances in accordance with a semi-persistent configuration. In some examples, the UE115-amay measure the CMR220and IMR25indicated in the control signaling, such as an aperiodic measurement report trigger received from the base station105-a, for generating an aperiodic L1-SINR report. The chosen periodic or semi-persistent instances may have the same time domain behavior (e.g., that the CMR220and the IMR225occur in a same time interval). For generating an aperiodic SINR report, the UE115-amay receive an aperiodic measurement trigger indicating a particular instance of a CMR220and an IMR225that each occur in a same time interval, may measure the indicated CMR220and IMR225, and may transmit an aperiodic measurement report that indicates the SINR determined by measuring the indicated CMR220and IMR225.

For a periodic or semi-persistent L1-SINR report, common time domain behavior between the first and second CSI resources settings may be periodic or semi-persistent. For instance, UE115-amay be configured by the base station105-awith a periodicity and/or a semi-persistent allocation of multiple instances of CMRs220and IMRs225where each of the instances of the CMRs220and IMRs225occur within a same time interval. The UE115-amay generate an L1-SINR report for some or each of those instances (e.g., for each CMR220). More details about the configurations of CMR220and IMR225may be/described with reference toFIG. 3.

In some cases, UE115-amay determine a QCL relationship between CMR220and IMR225to identify which receive beam to use for measuring the CMR220and IMR225for determining the L1-SINR. For instance, UE115-amay determine that the same QCL exists between each CMR220and associated IMR(s)225. If the base station105-ahas not transmitted control signaling to configure the UE115-awith a QCL relationship for one or more associated IMR(s)225to be measured, the UE115-amay determine that the QCL of the IMR225may be the same as that of the CMR220(e.g., the IMR225may follow QCL for the CMR220). For example, the UE115-amay receive control signaling that indicates a QCL relationship for the CMR220, and the UE115-amay use that same QCL relationship for the IMR225. The UE115-amay thus use a same receive beam (as indicated by the QCL relationship) for measuring each of the CMR220and the IMR225.

In another example, if the associated IMR(s)225already has QCL configured, base station105-amay ensure that the same QCL is configured for both CMR220and IMR225. For example, the UE115-amay receive control signaling from the base station105-athat indicates a QCL relationship for the IMR225. Because the base station105-ahas configured the QCL relationship for the IMR225, a base station105-amay use a transmit beam in accordance with the QCL relationship when transmitting a first reference signal in the CMR220and when transmitting a NZP or ZP reference signal in the IMR225. The UE115-amay thus use a same receive beam (as indicated by the QCL relationship for IMR225) for measuring each of the CMR220and the IMR225.

In an example, if the associated IMR(s)225has QCL configured but is different from QCL for CMR220, the IMR(s)225may follow QCL for CMR220. The base station105-amay, in some examples, transmit control signaling that configures the CMR220with a QCL relationship that differs from a QCL relationship configured for the IMR225. When the configured QCL relationships differ, the UE115-amay use a beam indicated by the QCL relationship for the CMR220when measuring the IMR225.

As such, the CMR220and associated IMRs225may have QCL configured to enable the UE115-ato know which receive beam to use to measure each of the CMR220and the associated IMR225, and the association may be determined by QCL matching.

Subsequent to receiving the measurement report, base station105-amay attempt to schedule the UE115-aand/or may select which beam pair to use for communication with the UE115-a. In an example, the base station105-areceive the measurement report and transmit a scheduling grant to UE115-a. UE115-aand base station105-amay communicate according to the scheduling grant, where such communications may include transmitting and receiving a data transmission (e.g., physical uplink shared channel (PUSCH) or physical downlink shared channel (PDSCH)), transmitting and receiving a control transmission (e.g., physical uplink control channel (PUCCH) or physical downlink control channel (PDCCH)), or both.

In an example, when base station105-areceives the measurement report, base station105-amay determine to use the same beam as was used to measure CMR220and IMR225for generating the measurement report. In such cases, base station105-amay transmit a beam command that indicates the same beam (e.g., indicates the same QCL relationship or no change to the previously indicated QCL relationship configured for measuring the CMR and/or IMR). In another example, base station105-amay receive the measurement report and may determine that the indicated SINR is too low. In such cases, base station105-amay instruct UE115-avia a beam command to switch beams for subsequent data transmission and/or SINR measurement reporting (e.g., configure the UE115-awith a new QCL relationship to indicate that the UE115-ais to use a different beam).

FIG. 3illustrates an example of a resource configuration300that supports time domain behavior and QCL relation for SINR measurement in accordance with aspects of the present disclosure. In some examples, resource configuration300may implement aspects of wireless communications system200.
