Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and including disjoint segments of resource blocks (RBs). The downlink control information may be located at least partially within a first segment of the disjoint segments and a second segment of the disjoint segments may be exclusive of the downlink control information. The downlink control information may include a grant of a set of resources for a downlink shared channel that overlaps with the CORESET. The UE may determine a rate matching operation for the wideband DMRS for a downlink shared channel for portions of the set of resources that overlap with the second segment of the disjoint segments, and receive the downlink shared channel on the set of resources according to the determined rate matching operation.

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: Methods, systems, and devices for wireless communications are described. A base station and a user terminal may communicate via a relaying satellite in a non-terrestrial network. The non-terrestrial network may cause communication disruptions in hybrid automatic repeat request (HARQ) processes due to communication delays. Base stations and user terminals communicating via a satellite may implement dynamically configurable HARQ processes to avoid latency in a wireless communications system.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may configure a UE to transmit a cross link interference reference signal (CLI-RS) using a bandwidth and frequency similar to those used for a synchronization signal. In another aspect, a BS may may configure a UE to measure a cross link interference reference signal (CLI-RS) transmitted using a bandwidth and frequency similar to those used for a synchronization signal. In other aspects, a base station may transmit, to a UE, an instruction to transmit or measure a CLI-RS. Numerous other aspects are provided.

Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a base station by performing an initial access procedure within an initial access bandwidth. In some cases, the UE may monitor for a cell specific configuration in the initial access bandwidth that indicate one or more first common search spaces within the initial access bandwidth that the UE may monitor for control information. Additionally, the UE may receive dedicated signaling after the initial access procedure that indicates a downlink bandwidth part (BWP) and one or more second common search spaces within the downlink BWP to monitor for control information. Accordingly, the UE may monitor the first common search spaces, the second common search spaces, or both based on the dedicated signaling.

Abstract: In the examples described herein, a user equipment (UE) may identify multiple carriers configured for communications with a base station, and the UE may group the carriers into one or more preferred groups for synchronized scheduling at the base station. The preferred groups of carriers for synchronized scheduling may represent a recommendation that carriers within a preferred group are to be scheduled for communications with the base station on at least partially overlapping resources to maximize power savings at the UE. The UE may transmit an indication of the preferred groups of carriers to the base station, and the base station may identify an actual group of carriers for synchronized scheduling based on the indication received from the UE. The base station may then schedule communications with the UE based on the actual group of carriers.

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.
