Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

Abstract: Methods, systems, and devices for wireless communication are described that provide for synchronization signal (SS) blocks in which synchronization signals and broadcast channel transmissions may be transmitted. Broadcast channel transmissions may be demodulated using SS transmissions, reference signal transmissions, or combinations thereof. Broadcast channel transmissions may be transmitted in a subset of SS block time resources, and synchronization signals may be transmitted in another subset of SS block time resources. Reference signals may be transmitted using tones within the broadcast channel time resources, and may be transmitted at a higher density for portions of the broadcast channel transmission bandwidth that are outside of the SS transmission bandwidth. Waveforms for reference signal transmissions, and information provided by reference signal transmissions may be provided.

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: Techniques for wireless communication are described. A method of wireless communication at a user equipment (UE) includes receiving a synchronization signal within a synchronization signal (SS) block; receiving at least a portion of a physical broadcast channel (PBCH) of the SS block, the PBCH comprising a self-decodable portion and an outside portion; and decoding the PBCH based at least in part on receiving the self-decodable portion of the PBCH. The synchronization signal has a first bandwidth. The self-decodable portion of the PBCH has a second bandwidth substantially within the first bandwidth. The outside portion having a bandwidth that is outside of the second bandwidth and within a PBCH bandwidth, the PBCH bandwidth being greater than the first bandwidth.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Aspects of the present disclosure provide for the transmission of various synchronization signals with variable periodicity. For synchronization signals with long periodicity, in some aspects of the disclosure, the synchronization signals may be transmitted as single-frequency-network (SFN) synchronization signals and/or the synchronization signals may be repeated a number (N) of times within a synchronization burst to reduce user equipment (UE) search latency and improve UE measurement accuracy. In some examples, the synchronization signals may be repeated within a synchronization burst using a repetition pattern that may be configurable based on the periodicity of transmission or fixed for one or more periodicities of transmission.

Abstract: Wireless communication devices are adapted to facilitate multiple synchronization channels within a single carrier. In some examples, an apparatus for wireless communication may transmit a first synchronization channel at a first frequency in a carrier bandwidth, and at least one additional synchronization channel at a different respective frequency in the carrier bandwidth. In some examples, an apparatus for wireless communication may scan a carrier bandwidth for one of a plurality of synchronization channels conveyed at different respective frequencies in the carrier bandwidth, and discover a synchronization channel from among the plurality of synchronization channels. The apparatus may further receive information conveyed over the discovered synchronization channel and utilize the information to access the carrier. Other aspects, embodiments, and features are also included.
