Abstract: In order to improve cell detection in NR, a user equipment apparatus performs a PSS search on a first frequency raster from a group of frequency rasters. When the UE detects a PSS on the first frequency raster corresponding to a PSS hypothesis, the UE searches for an SS on a second frequency raster based at least on part on the detected PSS hypothesis on the first frequency raster. The UE may search for a plurality of hypotheses of the SS corresponding to the detected PSS hypothesis on the first frequency raster and the second frequency raster. The second frequency raster may be selected from the group of frequency rasters based at least in part on the detected PSS hypothesis or the first frequency raster on which the PSS was detected.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may determine how densely user equipments are located in various regions surrounding the base station, and may assign more beams for transmission of an initial access signal in an area with more UEs. The apparatus may be a base station. The base station divides a region surrounding the base station into a plurality of sub-regions, where one region of the plurality of sub-regions covers a greater area than at least one other region of the plurality of sub-regions. The base station assigns each beam of a plurality of beams of the base station to a respective sub-region of the plurality of sub-regions. The base station transmits at least one initial access signal in each direction of the plurality of beams using a respective beam of the plurality of beams, each direction of the plurality of beams corresponding to a respective sub-region of the plurality of sub-regions.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines timing information associated with a synchronization signal to be transmitted. The timing information includes a hop count and a reliability indicator associated with the synchronization signal. The reliability indicator is independent of the hop count and indicates one of reliable or unreliable. The UE broadcasts the timing information with the synchronization signal. The hop count may be a number of hops the synchronization signal is from a base station synchronization signal received from a base station.

Abstract: Methods, systems, and devices for fast physical cell identifier (PCI) conflict detection are described. A user equipment (UE) may receive, via a serving cell, a first set of one or more signals indicating a first PCI of the serving cell. After receiving the first set of one or more signals, the UE may receive a control message indicating that the first PCI of the serving cell is changing to a second PCI. The UE may monitor for a second set of one or more signals indicating the second PCI based at least in part on the control message. The UE may receive the second set of one or more signals indicating the second PCI based on the control message, and communicate one or more messages with the serving cell based on the second PCI.
