Abstract: The present disclosure provides for adaptive resource management in new radio operations that adapts a numerology including a subcarrier spacing and/or cyclic prefix for a user equipment (UE) traveling at a high speed. A base station may transmit via a plurality of remote radio heads (RRH) to a user equipment (UE) is moving along a high speed track. The base station may transmit, in a first time period, using a first numerology including a first subcarrier spacing and a first cyclic prefix ratio, a first transmission for the UE. The base station may transmit, in a subsequent time period, using a second numerology including a second subcarrier spacing and a second cyclic prefix ratio, a second transmission for the UE. At least one of the second subcarrier spacing is different than the first subcarrier spacing or the second cyclic prefix ratio is different than the first cyclic prefix ratio.

Abstract: Aspects of the present disclosure describe synchronizing frequency and/or timing in a wireless communication system. A synchronization channel frequency can be determined as one of a plurality of possible synchronization channel frequencies within a frequency band. A tone of one or more synchronization signals that corresponds to the synchronization channel frequency can be punctured, and the one or more synchronization signals can be transmitted as centered around the synchronization channel frequency.

Abstract: Methods, systems, and devices for wireless communications are described for relayed sidelink communications in which a set of relays receives a groupcast sidelink communication from a source and relay the communication to a destination using cooperative multiple-input multiple-output (MIMO) techniques. A source, such as a source user equipment (UE), may reserve resources for the groupcast sidelink communication and the cooperative MIMO transmissions, and may transmit a resource reservation message with an indication of the reserved resources. The resource reservation message may be transmitted in a sidelink control information transmission, in a medium access control message, or any combinations thereof. In the event of a collision in reserved resources of multiple different sources, the sources or relays may determine a priority of each communication and transmit a selected communication based on the priority determination.

Abstract: Techniques are described herein for signaling procedures that use a hierarchical mobility, which may be applied when a user equipment (UE) is operating in a radio resource control (RRC) inactive state or the RRC idle state. A wireless communication system may be configured with a plurality of areas in which one or more networks are established for communicating certain types of signals. Examples of the areas associated with networks may include a tracking area (TA), a radio access network area code (RAN-AC), a radio access network based notification area (RNA). A synchronization signal or a paging signal may be transmitted using a first set of communication resources in a first area, while the synchronization signal or the paging signal may be transmitted using a second set of communication resources in a second area different than the first set of communication resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate sidelink messages over one or more carriers. The UE may schedule a first sidelink message for transmission on a first resource of a first carrier of a set of carriers on which the UE is configured for sidelink carrier aggregation. After scheduling the first sidelink message, the UE may schedule a second sidelink message for transmission on a second resource of a second carrier that at least partially overlaps in time with the first resource. The UE may determine that a transmission capability of the UE pertaining to the overlapping sidelink transmissions has been exceeded by scheduling the second sidelink message and may pre-empt transmission of the first sidelink message in favor of transmission of the second sidelink message based on the transmission capability of the UE being exceeded.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a resource allocation indicating a set of transmission tones comprising a set of data tones and a set of peak reduction tones (PRTs), wherein the resource allocation indicates locations for the set of data tones and locations for the set of PRTs within a particular bandwidth, wherein the locations for the set of PRTs are arranged relative to the locations for the set of data tones according to a PRT sequence, and wherein the PRT sequence comprises a plurality of contiguous PRTs arranged relative to a plurality of contiguous data tones or a pseudo-random pattern generated using a pseudo-random number generator; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.

Abstract: Techniques are described that provide for waveform selection for uplink (UL) and/or downlink (DL) wireless transmissions based on one or more factors associated with the wireless transmission, a transmitter that is to transmit the wireless transmission, or combinations thereof. UL and DL transmissions may use one of a number of different waveforms, such as single-carrier waveforms that use a single carrier for information transmission of a wireless channel, and multi-carrier waveforms that use multiple carriers at different frequencies to transmit some of the bits on each channel. Multi-carrier transmission waveforms or single-carrier waveforms may be selected for wireless transmissions based on a bandwidth allocated for the transmissions, a capability of a transmitter that is to transmit the transmissions, or combinations thereof.
