Abstract: A user equipment (UE) may obtain a first indication of a first measurement gap resource associated with a first time period. The UE may receive a set of position reference signals (PRSs) during a PRS occasion. A first portion of the PRS occasion may not overlap with any portion of the first time period. The UE may measure the set of PRSs at the first portion of the PRS occasion based on at least one of (i) the first measurement gap resource associated with the first time period, (ii) a second measurement gap resource associated with a second time period that overlaps with the first portion of the PRS occasion, or (iii) a positioning processing window (PPW) associated with a third time period that overlaps with the first portion of the PRS occasion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, while camped on a cell of a first radio access technology (RAT), a search for closed access group (CAG) cells of a second RAT different from the first RAT. The UE may populate a database based at least in part on the search, wherein populating the database includes associating the cell of the first RAT with one or more of the CAG cells of the second RAT. The UE may perform a reselection process from the cell of the first RAT to a first CAG cell of the second RAT, of the one or more CAG cells of the second RAT. Numerous other aspects are described.

Abstract: Aspects of the present disclosure generally relate to managing decoding of system information blocks (SIBs) at a user equipment (UE) and managing SIB transmissions at a base station. For example, the described aspects at the UE may include detecting a trigger event for decoding one or more SIBs received from a cell and determining to avoid decoding of at least one SIB received from the cell in response to the detected trigger event and a mobility pattern of the UE. The described aspect at the UE may further include using a stored version of the at least one SIB for communication with the first cell.

Abstract: The disclosure provides methods and apparatus to improve public land mobile network search time. A user equipment (UE) may determine a subset of channels within a frequency band based on a stored identifier of a channel used by a previously acquired cell, each channel in the subset being spaced from the channel used by the previously acquired cell by a different multiple of a set spacing, the set spacing being greater than a spacing between adjacent channels. The subset of channels may be scanned to determine a signal strength of each channel in the subset. The UE may rank each channel in the subset according to the determined signal strength of the channel and attempt to acquire a cell using a channel in the subset based on the ranking.

Abstract: The present disclosure presents a method and apparatus for improving uplink (UL) performance at a user equipment (UE). For example, the method may include identifying a random access channel (RACH) preamble failure when the UE is communicating with a current serving cell of the UE, increasing transmission power of successive RACH preambles based at least on the identifying, comparing signals received on a downlink at the UE via a first path and a second path from the current serving cell of the UE, and determining that a RACH preamble failure problem exists at the UE based at least on the comparing of the signals received on the downlink and identifying of successive RACH preamble failures. As such, improved performance uplink (UL) performance at a UE may be achieved.
