Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) served by a first cell and a second UE served by a second cell may experience cross link interference (CLI). The UEs may have different subcarrier spacing (SCS) configurations. For example, the uplink SCS of the aggressor UE may be different from the downlink SCS of the victim UE. The serving base stations may configure the UEs with one or more parameters for generating and measuring a signal used to manage the CLI. The parameters may be based on the uplink SCS of the aggressor and the downlink SCS of the victim. The aggressor UE may apply the parameters to generate the CLI measurement signal, and the victim UE may apply the parameters to measure the CLI measurement signal, so the signal from the transmitter fits into the resource grid of the receiver.

Abstract: Methods, systems, and devices for wireless communication are described that may enable a user equipment (UE) to monitor a shared spectrum to receive control signaling and data transmissions associated with different transmission time intervals (TTIs). For example, a base station may communicate with a UE according to a first transmission mode during a first, shortened TTI. The base station may transmit a downlink control channel for a shortened TTI based on a subset of a number of blind decodes or control channel elements. Additionally, a downlink control channel for a shortened TTI may contain grants for multiple TTIs. In some cases, the base station may transmit a signaling to the UE via a reference signal, downlink control channel, or radio resource control which may indicate a change from the shortened-TTI transmission mode to a transmission mode with a TTI duration that is longer than the first, shortened TTI duration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a carrier aggregation (CA) configuration for communications on a set of cells. The UE may determine that signals transmitted on the set of cells may be spatially quasi co-located based on the CA configuration and a predetermined relationship rule. For example, the UE may determine that the signals are spatially co-located based on receiving multiple synchronization signal blocks (SSBs) that have a same SSB index, receiving a common SSB, assuming that an SSB and reference signals sourced by the SSB are spatially quasi co-located, receiving a signal from a particular cell of the set of cells, or receiving a common spatial QCL relationship during a configured period of time. Once the spatial QCL relationship is determined, the UE may receive the signals transmitted on the set of cells based on the spatial QCL relationship.

Abstract: A method for speeding up a filter tracking speed includes scaling filter coefficients based at least in part on an uplink/downlink configuration in a time division duplex (TDD) or a multimedia broadcast single frequency network (MBSFN) system. The method also includes applying scaled filter coefficients during at least one downlink subframe to control a filter tracking speed.

Abstract: Techniques and apparatus for adapting bandwidth operation for full duplex user equipments (UEs) are described. One technique involves a base station (BS) determining a plurality of resource bandwidths (BWs) within an active BWP that are available to be used for communications by one or more UEs. An indication of at least one resource BW of the plurality of resource BWs is signaled to a UE. Communications between the BS and the UE are performed on the at least one resource BW.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect, using a low-power receiver of the UE, a low-power synchronization signal (LP-SS) that is associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block. The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for physical downlink control channel (PDCCH) aggregation across monitoring occasions. A method that may be performed by a user equipment (UE) includes determining a policy for monitoring one or more physical downlink control channels (PDCCHs), wherein the policy allows for mapping control channel elements (CCEs) of a single PDCCH candidate across multiple PDCCH monitoring occasions; and monitoring for signals from a network entity via the one or more PDCCHs according to the determined policy.
