Abstract: A network entity configures a synchronization signal block (SSB) using SSB resources that convey a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) within an SSB resource area of a resource grid bounded in time by a first configured integer number of time units and bounded in frequency by a second configured integer number of physical channels. A product of the first configured integer number and the second configured integer number is a predetermined constant value, each symbol of the SSB has an equal number of resource elements (REs), and all REs in the each symbol of the SSB, except REs within a frequency guard band between any two of the PSS, the SSS, and the PBCH in the each symbol of the SSB, have non-zero values. A user equipment receives the SSB in the SSB resources as a beamformed SSB.

Abstract: Disclosed are techniques for wireless positioning performed by a user equipment. For example, the method includes entering into a Radio Resource Control (RRC) inactive state. The method includes monitoring, during a first time interval, while the user equipment is in the RRC inactive state, one or more first bandwidth parts having a first bandwidth to perform a first operation. The method includes monitoring, during a second time interval, while the user equipment is in the RRC inactive state, one or more second bandwidth parts having a second bandwidth to perform a second operation. The second bandwidth is different than the second bandwidth.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a set of resources to be used for reception of a synchronization signal block (SSB) overlaps at least one of a set of resources to be used for a first uplink transmission or a set of resources to be used for a second uplink transmission. The set of resources to be used for the first uplink transmission may overlap the set of resources to be used for the second uplink transmission. The first uplink transmission and the second uplink transmission may have a same priority index value. The UE may resolve an overlap between the first uplink transmission and the second uplink transmission and then resolve an overlap associated with the reception of the SSB. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may obtain configuration information that identifies resources for sounding reference signal (SRS) positioning. The UE may transmit, to a reconfigurable intelligent surface (RIS), a plurality of SRS transmissions at different times according to the configuration information. The UE may receive, from the RIS, a plurality of SRS transmissions comprising reflections of the plurality of SRS transmissions to the RIS, wherein each of the plurality of SRS transmissions from the RIS is transmitted at a different angle of departure (AoD) from the RIS. The UE may measure each of the plurality of SRS transmissions from the RIS to produce a plurality of measurements. The UE may perform a positioning operation based on the plurality of measurements.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a distance between an end of a first downlink control information (DCI) and a corresponding first physical downlink shared channel (PDSCH) and a distance between an end of a second DCI and a corresponding second PDSCH satisfy a minimum distance threshold for a user equipment (UE). The ends of the DCIs are to be received at the same symbol. The base station may transmit the first DCI, the first PDSCH, the second DCI, and the second PDSCH based at least in part on determining that the distances satisfy the minimum distance threshold. In some aspects, the UE may decode the first and second DCIs in an order that depends on DCI properties. Numerous other aspects are provided.

Abstract: Cell reselection and other operations involving signal measurements at a UE may increase the power consumption and operation complexity at a UE, such as a reduced capacity UE (RedCap UE). In some scenarios, for example, a UE may need to frequently switch to bandwidth parts (BWPs) outside the bandwidth of its initial DL bandwidth part to receive and measure synchronization signal blocks (SSBs) for cell reselection, which increases the power consumption of the UE. The aspects described herein allow a UE to measure SSBs in one or more bandwidth parts that is not an initial DL bandwidth part configured by a serving cell of the UE in response to an event trigger or a message received at the UE. The SSBs may be associated with the serving cell of the UE or with a non-serving cell. The UE performs a cell reselection operation based on the measurements.

Abstract: Apparatuses and methods for mobility enhancements and power saving considerations for UE are described. An apparatus is configured to operate on an active DL BWP in a source node, where the active DL BWP is not a default DL BWP associated with the UE, and start a BWP inactivity timer at the UE that triggers a BWP switch from an active DL BWP to the default DL BWP after the BWP inactivity timer expires at a first expiration time. The apparatus is also configured to report a measurement of at least one of the source node or a target node, and start a mobility reception timer based on a condition associated with at least one of the measurement of the source node being below a first signal quality threshold or the measurement of the target node being above a second signal quality threshold.
