Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive RACH configuration information on a downlink carrier of a first set of carriers, wherein the RACH configuration information pertains to the first set of carriers and to a second set of carriers; and selectively perform a RACH procedure with regard to the first set of carriers or the second set of carriers based at least in part on the RACH configuration information. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide procedures for new radio (NR) cell measurement. According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving one or more downlink signals from a cell, wherein the cell is of a first cell type that supports a first set of functions or a second cell type that supports a second set of functions, wherein the second set of functions is different than the first set of functions; determining a cell type of the cell based on the one or more downlink signals; and communicating with the cell based on the determination.

Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Methods, systems, and devices for wireless communication are described. A device—such as a base station or user equipment (UE)—may transmit a demodulation reference signal (DMRS) including signaling information in addition to channel estimation information. To improve reception of the DMRS signaling information, the transmitting device may employ data protection techniques to the signaling information and modify a data payload transmitted in the physical data channel associated with the DMRS. In one aspect, the transmitting device may modify cyclic redundancy check (CRC) bits in the payload to include verification for the signaling information. In another aspect, the transmitting device may determine a scrambling code based on the signaling information, and may scramble the payload based on the scrambling code.

Abstract: Aspects of the present disclosure describe acquiring a synchronization signal transmitted at a frequency location. An ordered list of possible frequency locations within a frequency band at which the synchronization signal may be transmitted can be obtained. The synchronization signal can be searched for at one or more possible frequency locations in the ordered list of possible frequency locations, where the searching is performed according to an order indicated in the ordered list of possible frequency locations.

Abstract: Split synchronization signal configuration for unified synchronization channels and techniques for indicating communication block boundaries in wireless communication systems that use a unified synchronization signal configuration that may be used in different communication modes are described. The disclosed split synchronization signal configuration allows the same synchronization signal configuration to be used in different communication modes (or numerologies) that operate on different frequencies. The boundary indication techniques of embodiments allow efficient indication of the beginning of a communication block (such as a frame, subframe, or slot) relative to the beginning of a unified synchronization signal configuration.
