Abstract: A wireless entity, such as a user equipment (UE) or transmission reception point (TRP), receives and processes aggregated positioning reference signals (PRS) to increase the effective PRS bandwidth, thereby increasing positioning accuracy, such as time of arrival measurements. An aggregated PRS includes one or more PRS components that are transmitted from a same transmitting entity. Each PRS component may be, e.g., a separate PRS resource associated with a contiguous frequency-domain bandwidth or may be, e.g., a plurality of frequency-domain bandwidths spanned by a single PRS resource. PRS components of an aggregated PRS that are unpunctured, e.g., do not collide with higher priority signals, are aligned in time domain, and are configured with common constraints are processed jointly assuming that the PRS components are transmitted from a same antenna port, thereby increasing the effective PRS bandwidth.

Abstract: Aspects are presented which enable a UE to determine a supplementary uplink (SUL) configuration for an uplink cancellation indication (ULCI) for cancelling uplink communications in SUL. The UE receives from a base station a first configuration associated with a first block of an ULCI and associated with at least one of a SUL carrier a non-supplementary uplink (NUL) carrier in a cell. The base station configures the UE with a second configuration associated with a second block of the ULCI and associated with a SUL carrier in the cell, and the UE determines the second configuration. The UE monitors the ULCI based on the first configuration and the second configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a first set of downlink control information (DCI) formats is associated with a same DCI size as a second set of DCI formats, and perform a padding operation so that the first set of DCI formats and the second set of DCI formats are associated with different DCI sizes. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.

Abstract: A base station may transmit a broadcast/multicast service in a multicast broadcast single frequency network (MBSFN) area multicast communication. A method of wireless communication at a base station in accordance with an aspect of the present disclosure comprises determining a broadcast/multicast service to be provided to a user equipment (UE) in a multicast broadcast single frequency network (MBSFN) area, and transmitting a tracking reference signal (TRS) to the UE, the TRS indicating information associated with receiving the broadcast/multicast service by the UE.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for transmitting multiplexed sounding reference signal (SRS) ports in communications systems operating according to new radio (NR) technologies. An exemplary method includes obtaining an indication of a technique to use in transmitting sounding reference signals (SRS) via five or more antenna ports in one slot and transmitting the SRS via the five or more antenna ports according to the indicated technique.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more measurement reference resources, of a plurality of measurement reference resources, are preempted; and, based at least in part on the determination, selectively: cancel transmission of a measurement report, or transmit the measurement report based at least in part on at least a portion of the plurality of measurement reference resources. In some aspects, the UE may determine that one or more uplink reference signal resources, of a plurality of uplink reference signal resources, are to be preempted; and, based at least in part on the determination, selectively: cancel transmission of an uplink reference signal, or transmit the uplink reference signal based at least in part on at least a portion of the plurality of uplink reference signal resources.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encored on computer storage media, for fifth generation (5G)-new radio (NR) physical layer (PHY) timing synchronization. In one aspect, a user equipment (UE) computing device may determine a new timing advance (TA) between downlink frames and uplink frames (NTA_new) for a base station (BS) and determine whether the NTA_new may be within a timing advance acceptable range. In another aspect, a BS may determine a timing advance command (TA) for a timing advance group (TAG) for the BS, and send the TA to the UE computing device. In determining the timing advance command, the TA may be configured by the BS to cause the UE computing device to determine that a new timing advance between downlink frames and uplink frames (NTA_new) for the BS using the TA is within a timing advance acceptable range.

Abstract: Aspects of the present disclosure provide techniques for enhanced transmission time interval (TTI) bundling design for machine type communications (MTC). A method for wireless communications by a wireless device is provided. The method generally includes determining a mapping of one or more uplink or downlink channels to one or more fixed bundling sizes, wherein each of the one or more fixed bundling sizes indicates a number of transmission time intervals (TTIs) over which a channel should be transmitted and processing transmission of the one or more uplink or downlink channels based on the mapping.
