DETAILED DESCRIPTION

In wireless communications systems, a user equipment (UE) and one or more base stations may communicate with each other. For instance, a first UE may be served by a first base station and a second UE may be served by a second base station (e.g., neighboring base station). When both base stations are in simultaneous communication, a signal from the second base station (e.g., neighboring base station) may interfere with a reception at the first UE. Similarly, a signal from the first base station may interfere with a reception at the second UE. Such an interference may be referred to as downlink jamming. To reduce downlink jamming, some wireless communications systems may provide for UEs to use channel state information reference signals to identify an interference level. The UEs may then explicitly report the downlink jamming or the interference level, based on the channel state information reference signals. However, reference signal-based interference management may be perform using a channel state information reference signal configuration. In some examples, the measurement using the channel state information reference signal may not be available.

Aspects of the present disclosure provide for techniques to utilize received signal strength indicator measurement to identify and report downlink jamming (interference caused by downlink transmissions of a neighboring base station). In some examples, a UE may receive a control signaling from a serving base station. The control signaling may indicate a received signal strength indicator resource pattern to monitor for interference caused by downlink transmission from a second base station (e.g., neighboring base station). For example, the resource pattern may indicate a resource configuration for received signal strength indicator measurement. The UE may perform a received signal strength indicator measurement of the downlink transmission from the second base station in accordance with the resource pattern. The UE may then report the received signal strength indicator measurement to the serving base station. The serving base station may adjust scheduling of the UE to avoid downlink jamming by the neighbor base station based on the feedback from the UE.

Particular aspects of the subject matter described herein may be implemented to realize one or more advantages. The described techniques may support improvements in interference management in wireless communications systems by reducing signaling overhead. Further, in some examples, the interference management using a resource pattern as described herein may support higher data rates, thereby improving latency and reliability. As such, supported techniques may include improved network operations, and, in some examples, may promote network efficiencies, among other benefits

Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are further illustrated by a received signal strength indicator resource configuration and process flows. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to received signal strength indicator configuration and reporting.

In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrow band IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access for different types of devices.

Some wireless communications systems may experience cross link interference among different links. Cross link interference may be experienced from dynamic frame configuration. For example, cross link interference may occur between two or more base stations or UEs (between uplink and downlink). In the case if cross link interference between two UEs, reference signal received power and received signal strength indicator may be configured to measure the interference. Additionally or alternatively, cross link interference may be from aligned frames. In some examples, a first UE may be served by a first base station and a second UE may be served by a neighboring base station. Often times, a signal from the neighboring base station may interfere with a reception at the first UE. Similarly, a signal from the first base station may interfere with a reception at the second UE. Such interference may be known as downlink jamming.

In some examples, the interference (cross link interference) may be from one UE to another nearby UE. Cross link interference may occur when a base station configures different time domain uplink and downlink slot formats to nearby UEs. When a first UE is transmitting, a second UE (not the intended recipient) may receive this transmission as cross link interference in its downlink symbols if first UE's uplink symbol collides with at least one downlink symbol of second UE. In addition, the cross link interference can occur between two UEs on the same cell or on different cells. In some examples, the second UE may participate in a signaling and procedure to measure cross link interference from the first UE. In such cases, the first UE may not transmit a dedicated signal for cross link interference measurement by another UE and is not aware of an uplink transmission measured by the second UE. The second UE may measure the cross link interference if the base station configures one or more cross link interference measurement resources to it. The cross link interference measurement may defined as periodic measurement based on sounding reference signal reference signal received power or received signal strength indicator. Based on the cross link interference measurement report, the base station can manage the scheduling of UEs to balance the throughput of different UEs. In some examples, a channel state information report may include a channel quality indicator, a precoding matrix indicator, a channel state information reference signal resource indicator, a strongest layer indication, a rank indication and a reference signal received power for beam management.

Higher layer configuration at UE may include N≥1 channel state information reporting settings, M≥1 resource settings, and L≥1 channel state information measurement links. If channel state information interference measurement resources are configured in a resource setting, channel state information interference measurement resources may be used got inter-cell interference measurement and the channel state information interference measurement resources can be shared with UEs within the serving cell. Interference information may be implicitly indicated as a feedback to the base station via channel quality indication (quantized spectrum efficiency). The configurations can support the reference signal-based L1 and L3 inter-cell interference measurement.

Some wireless communications systems support L3 channel state information reference signal for L3 reference signal receive power measurement. However, such L3 channel state information reference signal measurement techniques are deficient. In comparison to L3 reference signal receive power, L3 received signal strength indicator may have one or more advantages. The received signal strength indicator can be measured with low complexity. For example, a maximum received signal strength indicator resource supported by UE may be much larger (at least twice) than that for reference signal receive power measurement resources. In some instances. a per slot maximum number of received signal strength indicator resources may not be used by the wireless communications system. In comparison, a maximum number of reference signal receive power resources per slot may be defined, which is much smaller than the total number of reference signal receive power resources across a slot. Additionally or alternatively, received signal strength indicator measurement may be captured from any neighboring cell downlink transmission (e.g., physical downlink shared channel, physical downlink control channel) that may affect the UE. That is, there may be a lot of more opportunities for the UE to measure the received signal strength indicator.

In some examples, received signal strength indicator measurement may reflect the time domain uplink and downlink configuration difference between the serving cell and neighboring cells. This can be more stable than the channel state information reference signal configuration for neighboring cell's UEs. The configuration of channel state information reference signal for neighboring cells may frequently change. In contrast, the configuration of received signal strength indicator measurement can be less often updated. Thus, received signal strength indicator measurement may have less signaling overhead for the configuration.

In some instances, a reference signal for channel state information may not explicitly indicate the interference level. The reference signal-based interference measurement can be L1 or L3 configuration. However, the reference signal-based management may include a reference signal configuration. Thus, such measurements may not be available. In addition, the reference signal-based measurement may involve large resource cost, and the corresponding channel state information reference signal reference signal receive power processing may be more complicated. In some examples, radio frequency and timing advance tracking may not be accurate for interference measurement. For example, a default downlink reception timing advance may not match a received timing advance from adjacent cells.

According to one or more aspects of the present disclosure, the UE115and the base station105may support a received signal strength indicator configuration for the downlink jamming interference management from adjacent cells. As such, the received signal strength indicator measurement may be used with one configuration (e.g., one static configuration), with limited configuration cost. In addition, the received signal strength indicator may not have a high reception complexity. The received signal strength indicator resource may also be available, and the UE115can detect the interference at any time.

In some examples, a UE115may receive a control signaling from a serving base station105. The control signaling may indicate a resource pattern (e.g., a received signal strength indicator resource pattern) to monitor for interference caused by downlink transmission from a second base station105(e.g., neighboring base station). The UE115may perform a received signal strength indicator measurement of the downlink transmission from the second base station105in accordance with the resource pattern. The UE115then reports the received signal strength indicator measurement to the serving base station105. The serving base station105may adjust scheduling of the UE115to avoid downlink jamming by the neighbor base station105based on the feedback from the UE115.

FIG.2illustrates an example of a wireless communications system200that supports received signal strength indicator configuration and reporting in accordance with aspects of the present disclosure. In some examples, the wireless communications system200may implement or be implemented by aspects of the wireless communications system100. For example, the wireless communications system200may include a UE115-a, a base station105-aand a base station105-b, which may be examples of a UE115and a base station105as described with reference toFIG.1.

The base station105-amay be a serving base station for the UE115-aand the base station105-bmay be a neighboring base station (e.g., a second base station). The UE115-amay communicate with the base station105-ain a geographic coverage area110-asupported by the base station105-a. Additionally, the UE115-amay communicate with the base station105-bin a geographic coverage area110-bsupported by the base station105-b. The geographic coverage area110-aand the geographic coverage area110-bmay be examples of a geographic coverage area110as described with reference toFIG.1.

As depicted in the example ofFIG.1, the base station105-amay transmit one or more downlink signals to the UE115-avia a communications link205(e.g., a downlink communications link) and the UE115-amay transmit one or more uplink signals to the base station105-avia a communications link210(e.g., an uplink communications link). In some cases, the UE115-amay be configured by the base station105-awith a resource pattern. In particular, the UE115-amay receive, from the serving base station105-a, control signaling indicating the resource pattern to monitor for interference caused by downlink transmissions from a second base station105-b.

In some wireless communications systems, a first UE may be served by a first base station and a second UE may be served by a neighboring base station. Often, a signal from the neighboring base station may interfere with a reception at the first UE. Similarly, a signal from the first base station may interfere with a reception at the second UE. Such interference may be referred to as downlink jamming. To reduce downlink jamming, some wireless communications systems may provide for UEs to use channel state information reference signals to identify an interference level. The UEs may explicitly report the downlink jamming or the interference level, based on the channel state information reference signal. However, the reference signal-based interference management may not be available.

One or more aspects of the present disclosure provide for a method to utilize received signal strength indicator measurement to identify and report downlink jamming. As depicted in the example ofFIG.2, the UE115-amay identify the downlink jamming220caused by the base station105-b. The base station105-a(serving base station) and the base station105-b(neighboring base station) may perform a slot format exchange using a communications link215. The UE115-amay receive control signaling via the communications link205. The control signaling may indicate a resource pattern to monitor for interference caused by downlink transmission from a second base station (e.g., neighboring base station105-b). The serving base station105-amay use the slot format of the neighboring base station105-bto select the resource pattern. For example, the resource pattern may indicates time and frequency resources in which the neighboring base station105-bis transmitting downlink signaling in accordance with its slot format. The serving base station105-amay send control signaling that indicates the resource pattern to enable the UE115-ato perform received signal strength indicator (RSSI) measurement of one or more resources indicated in the resource pattern. For example, the UE115-amay perform a received signal strength indicator measurement of the downlink transmissions from the second base station105-bin accordance with the resource pattern. In some examples, the received signal strength indicator resource associated with downlink signals may be at least one of a physical downlink shared channel, a demodulation reference signal, a physical downlink control channel, or a combination thereof.

The UE115-amay then report the received signal strength indicator measurement to the serving base station105-a. Upon receiving the measurement report from the UE115-a, the serving base station105-amay adjust scheduling of the UE115-ato avoid downlink jamming by the neighbor base station105-bbased on the feedback from the UE115-a. Thus, the aspects depicted herein provide a received signal strength indicator configuration and measurement reporting. The procedure for received signal strength indicator configuration and reporting may be transparent to the neighboring base station105-b. The techniques depicted herein may also be achieved with a dedicated resource for the received signal strength indicator measurement.

In some examples, the network (or serving base station105-a) may configure the conditions, which triggers the received signal strength indicator measurement reporting by the UE115-a. For example, the UE115-amay be configured to report RSSI measurement of each resource of the configured received signal strength indicator resources in the resource pattern. That is, in a default mode, the UE115-amay receive the control signaling indicating to report a received signal strength indicator measurement for each resource of a set of resources of the resource pattern. In some examples, the serving base station105-amay configure the UE115-ato report the received signal strength indicator resource measurement when larger than the pre-defined threshold, and an identifier of the resource (e.g., a resource index). The pre-defined threshold may be indicated using a threshold message configuration in a received signal strength indicator RRC signaling. In another example, the UE115-amay receive the control signaling indicating that the UE is to transmit the measurement report when a received signal strength indicator measurement of any resource in the set of resources of the resource pattern satisfies a threshold and may also indicate the measured resource (e.g., a resource index).

Additionally or alternatively, in a given resource pattern, the UE115-amay be configured to report K received signal strength indicator resources with the largest observed RSSI values. A configuration for the K values may be indicated to the UE115-avia received signal strength indicator RRC signaling. For example, the UE115-amay receive the control signaling indicating a quantity number of resources from the resource pattern on which the UE is to report. In some examples, the measurement report may include indications of received signal strength indicator measurements for the quantity number of resources from the resource pattern. For example, the control signaling may configure the UE115-ato report the K resources in the resource pattern having the highest received signal strength indicator measurements. For example, the resource pattern may include 10 different time and frequency resources. The UE may report the 4 resources having the highest observed received signal strength indicator measurements, a respective index of the 4 resources, and indicate a respective RSSI measurement for the 4 resources.

According to one or more aspects depicted herein, the serving base station105-amay configure the UE115-ato report information based on the received signal strength indicator resource. In some instances, the serving base station105-amay configure the UE115-ato report measurement results for the reported received signal strength indicator resources and a received signal strength indicator resource index. That is, the UE115-amay transmit, to the serving base station105-a, the measurement report including the received signal strength indicator measurement for a resource of the resource pattern, an index of the resource of the resource pattern, or both.

A cross link interference resource may be used by one a UE to perform cross link interference measurement between two or more UEs. For instance, the interference may be from an uplink transmission of a first UE to a downlink reception of a second UE. In some examples, the cross link interference resource can be re-used for downlink jamming received signal strength indicator measurement. For instance, the UE115-amay use resources configured for measuring cross link interference to perform the received signal strength indicator measurement of downlink jamming by a base station. For example, the UE115-amay receive, from the serving base station105-a, the control signaling indicating that the resource pattern includes a cross link interference resource and a bit indicating for the UE monitor for interference caused by the downlink transmissions from the second base station105-busing the cross link interference resource. In the control signaling (RRC signaling) indicating the cross link interference-received signal strength indicator configuration, the serving base station105-amay include the one element (e.g., 1 bit) to indicate whether the measurement is of downlink jamming or cross link interference between UEs. Cross link interference received signal strength indicator and downlink jamming received signal strength indicator measurements may hold different configurations (e.g., measurement timing). In some examples, the one element (e.g., 1 bit) may indicate to the UE115-ahow to make the measurement of the received signal strength indicator.

The UE115-amay transmit UE capability information indicating a received signal strength indicator measurement capability for interference measurement, where the control signaling is received based on the UE capability information. The received signal strength indicator measurement capability may indicate at least one of a defined or maximum number of resources across a plurality of slots the UE is capable of measuring, a defined or maximum number of measurement resources per slot the UE is capable of measuring, or both. According to some aspects, a received signal strength indicator measurement capability may be defined for jamming measurement for at least one of the defined or maximum number of received signal strength indicator measurement resources across slots, the defined or maximum number of received signal strength indicator measurement resources per slot, or both. In some examples, a joint received signal strength indicator measurement capability may be defined for total resource number of cross link interference received signal strength indicator resources and received signal strength indicator resources for neighbor cell measurement. For example, the serving base station105-amay define the overall number of the resources for jamming measurement to not be larger than 20. The UE115-amay transmit UE capability information indicating a joint measurement capability that identifies a number of resources the UE is capable of measuring for cross link interference and neighbor cell interference. In some examples, the control signaling may be received based on the UE capability information.

In some examples, the UE115-amay transmit a capability to reuse the capability for the defined or maximum number of cross link interference received signal strength indicator measurement resources. The UE115-amay transmit UE capability information indicating a number of cross link interference resources the UE is capable of measuring. In some examples, the control signaling may be received based on the UE capability information. Thus, the UE that supports cross link interference received signal strength indicator measurement can also afford the complexity for received signal strength indicator neighbor cell measurement for downlink jamming management.

In some examples, the UE115-amay receive, from the serving base station105-a, the timing assistance information including an identifier of a second UE served by the second base station105-b. The UE115-amay then receive, from the second UE based on the identifier, a quasi-colocation parameter associated with a synchronization signal block transmission from the second base station105-b. For instance, if UEs are close to the one neighbor cell's UE, then it may be assumed that the two UEs hold the same downlink timing. The UE115-amay then determine a timing of the synchronization signal block transmission for the neighbor base station based on the quasi-colocation parameter. In some examples, the received signal strength indicator measurement may be performed based on the timing. In other cases, the UE115-amay directly use self-downlink reception timing to measure the received signal strength indicator for downlink jamming. In some examples, the received signal strength indicator timing indication configuration may be defined in the RRC message (RSSI-Measurement-ResourceConfig-DL jamming). The configuration may include an indication of synchronization signal block for timing or UE identifier for timing. The RRC message may further indicate the corresponding quasi-colocation parameter. In some examples, the RRC message may indicate the UE to use the self-downlink reception timing.

FIG.3illustrates an example of a process flow300that supports received signal strength indicator configuration and reporting in accordance with aspects of the present disclosure. In some examples, the process flow300may implement aspects of wireless communications system100and the wireless communications system200described with reference toFIGS.1and2, respectively. For example, the process flow300may be based on one or more rules for received signal strength indicator configuration and reporting in wireless communications systems. The process flow300describes a low complicity procedure for neighbor cell interference measurement and identification. The process flow300may be implemented by the UE315and the base station305for reduced power consumption, and may promote low latency and low interference for wireless communications supporting high priority channels, among other benefits. The base station305and the UE315may be examples of a base station105and a UE115, as described with reference toFIGS.1and2.

In the following description of the process flow300, the operations between the base station305and the UE315may be transmitted in a different order than the example order shown, or the operations performed by the base station305and the UE315may be performed in different orders or at different times. Some operations may also be omitted from the process flow300, and other operations may be added to the process flow300.

The base station305may be a serving base station. A serving cell (including the base station305) may configure the UE315to measure received signal strength indicator for jamming caused by signals transmitted from neighboring cells. Additionally or alternatively, the UE315may be configured with received signal strength indicator measurement resources for multiple neighboring cells.

At320, the base station305may transmit a received signal strength indicator configuration. For example, the base station505may transmit a control signaling indicating a resource pattern to monitor for interference caused by downlink transmissions from a second base station.

At325, the UE315may transmit a measurement report including an indication of a received signal strength indicator measurement of the downlink transmissions from the second base station performed in accordance with the resource pattern. In some examples, the UE315may report the measurement result to the base station305if the measurement for a resource is above a threshold. In some examples, the UE315may report received signal strength indicator measurement based on an event triggered report for a neighboring cell (e.g., when a strong jamming signal received signal strength indicator is detected).

At330, the base station305may transmit a reference signal received power configuration. The base station305may transmit, in response to the measurement report, a control message indicating a reference signal received power measurement resource. For example, the base station305may configure reference signal received power measurement channel state information reference signal resources for neighbor cells reported by the UE315.

At335, the UE315performs a reference signal received power measurement of the reference signal received power measurement resource. At340, the UE315may transmit a measurement report including an indication of the reference signal received power measurement. In some examples, the measurement report may be a periodic measurement report.

FIG.4illustrates an example of a received signal strength indicator resource configuration400that supports received signal strength indicator configuration and reporting in accordance with aspects of the present disclosure. In some examples, the received signal strength indicator resource configuration400may implement aspects of wireless communications system100and the wireless communications system200as depicted with reference toFIGS.1and2. In some examples, the received signal strength indicator resource configuration400may be implemented by a base station105and one or more UEs115. The base station105and the UE115may be examples of a base station105and a UE115, as described with reference toFIGS.1and2.

According to one or more aspects, a UE may receive, from a serving base station, control signaling indicating a resource pattern to monitor for interference caused by downlink transmissions from a second base station. In some examples, the control signaling may be RRC signaling. In some examples, the UE may receive the control signaling indicating a slot duration, a periodicity, a slot index, or any combination thereof, for the resource pattern. The RRC message (RSSI-Measurement-ResourceConfig-DL jamming) may include an allowed size of the measurement bandwidth (nrofPRBs), a starting physical resource block index of the measurement bandwidth (startPRB), an OFDM symbol location of the received signal strength indicator resource within a slot (startPosition), a reference subcarrier spacing for received signal strength indicator measurement (Reference-Subcarrier-Spacing), and periodicity and the slot index to indicate the slot pattern (PeriodicityAndOffset). The RRC message may further indicate a number of symbols (nrofSymbols). Within a slot that is configured for received signal strength indicator measurement, the UE may measure the received signal strength indicator from startPosition to startPosition+nrofSymbols−1. The UE may then perform a received signal strength indicator measurement of the downlink transmissions from the second base station in accordance with the resource pattern. In some examples, the received signal strength indicator measurement may be performed based on at least one of the slot duration, the periodicity, or the slot index.

As depicted in the example ofFIG.4, a base station may configure a slot duration of a resource pattern for received signal strength indicator measurement, which corresponds to one value of periodicity among the periodicity set (i.e., {10 ms, 20 ms, 40 ms, 80 ms, 160 ms, 320 ms, 640 ms}). In some examples, the base station may configure the slot index in the periodicity, as shown in Table 1:

The UE may determine a location of received signal strength indicator resource403based on receiving the RRC signaling. The RRC signaling may indicate a periodicity of 10 slots and an offset of 2 slots, to indicate the resource pattern that the UE is to measure for RSSI. The RRC signaling may further indicate that the received signal strength indicator resource is located at a time period starting with slot402-a(e.g., slot10). The received signal strength indicator resource may occur periodically and is located at a time period starting with slot402-b(e.g., slot20) and at a time period starting with slot402-c(e.g., slot30). As depicted in the example ofFIG.4, the UE may determine that the received signal strength indicator resource403-ais location in slot12(by applying an offset of 2 slots starting from slot10). Similarly, the UE may determine that the received signal strength indicator resource403-bis location in slot22(by applying an offset of 2 slots starting from slot20). Additionally or alternatively, the UE may determine that the received signal strength indicator resource403-cis location in slot32(by applying an offset of 2 slots starting from slot30). Within a slot that is configured for received signal strength indicator measurement, the UE may measure the received signal strength indicator from startPosition to startPosition (3)+nrofSymbols(3)−1. For example, with a starting physical resource block index 1, the UE may calculate a number of resource blocks (e.g., 8 resource blocks starting from resource block 1 to resource block 8).

FIG.5illustrates an example of a process flow500that supports received signal strength indicator configuration and reporting in accordance with aspects of the present disclosure. In some examples, the process flow500may implement aspects of wireless communications system100and the wireless communications system200described with reference toFIGS.1and2, respectively. For example, the process flow500may be based on one or more rules for received signal strength indicator configuration and reporting in wireless communications systems. The process flow500may be implemented by the UE515, a serving base station505-band a neighboring base station505-afor reduced power consumption, and may promote low latency and low interference for wireless communications supporting high priority channels, among other benefits. The UE515, the serving base station505-band the neighboring base station505-amay be examples of a base station105and a UE115, as described with reference toFIGS.1and2.

In the following description of the process flow500, the operations between the UE515, the serving base station505-band the neighboring base station505-amay be transmitted in a different order than the example order shown, or the operations performed by the UE515, the serving base station505-band the neighboring base station505-amay be performed in different orders or at different times. Some operations may also be omitted from the process flow500, and other operations may be added to the process flow500. According to aspects depicted herein, the UE515may receive timing assistance information corresponding to the downlink transmissions from the neighboring base station505-a.

At520, the neighboring base station505-amay transmit, to the serving base station505-b, a quasi-colocation parameter associated with a synchronization signal block transmission. At525, the serving base station505-amay transmit, to the UE515, the quasi-colocation parameter associated with a synchronization signal block transmission. As depicted herein, the UE515may receive the timing assistance information including a quasi-colocation parameter associated with a synchronization signal block transmission from the neighboring base station505-a. For example, the serving base station505-bmay configure the UE515with the quasi-colocation parameter with a neighboring cell's synchronization signal block, for the UE515to determine timing of the received signal strength indicator measurement for downlink jamming. The configured quasi-colocation parameter may be helpful for the UE515to estimate the synchronization signal block, and to determine the timing for the received signal strength indicator measurement.

At530, the UE515may receive a synchronization signal block from the neighboring base station505-a. At535, the UE515may determine a timing of the synchronization signal block transmission based on the quasi-colocation parameter, and may use the determined timing for performing RSSI measurements of other downlink transmissions by the neighboring base station505-a. At540, the UE515performs at least one received signal strength indicator measurement of one or more downlink transmissions by the neighboring base station505-ain at least one resource of the resource pattern using the timing.
