Abstract: Aspects relate to sounding reference signal (SRS) time-domain bundling. Phase continuity may be maintained across SRS transmissions over multiple SRS occasions to enable a receiver to jointly process these SRS transmissions. In some examples, a user equipment may expect to be configured with SRS transmissions over multiple SRS occasions where SRS configurations for different SRS transmissions over different SRS occasions specify the same parameters. For example, a first SRS configuration for a first SRS transmission over a first SRS occasion may specify a first set of spatial relation information. In addition, a second SRS configuration for a second SRS transmission over a second SRS occasion may specify that same first set of spatial relation information. In this way, phase continuity may be maintained between the first SRS transmission over the first SRS occasion and the second SRS transmission over the second SRS occasion.

Abstract: Aspects relate to mechanisms for wireless communication devices for tone reservation. A user equipment (UE) receives an indication of one or more peak-reduction tone (PRT) resources for a transmission of one or more signals for a base station. The UE transmits a first signal to the base station on an uplink. The UE transmits a second signal to a relay entity on a sidelink for reception by the base station. The second signal is transmitted on the sidelink utilizing the one or more PRT resources.

Abstract: Aspects of the disclosure relate to random access procedures. In one example, a UE initiates a random access procedure with a base station, and receives a random access response (RAR) message from the base station in response to the initiating of the random access procedure. The UE further determines a redundancy version (RV) pattern comprising a sequence of a plurality of RVs. The UE also transmits an uplink (UL) communication to the base station as part of the random access procedure. The UL communication comprises a plurality of repetitions of a UL message, each repetition being an iteration of the UL message that is configured by applying a respective RV of the plurality of RVs to the UL message based on the sequence. The UE further receives a downlink message from the base station based on the UL message. Other aspects, embodiments, and features are also claimed and described.

Abstract: A method for wireless communication by a user equipment (UE) includes transmitting, to a base station, a random access preamble to initiate a random access procedure. The method also includes receiving, from the base station based on transmitting the random access preamble, a downlink message comprising a repetition number indicator. The method further includes transmitting a number of repetitions of a physical uplink channel based on the repetition number indicator.

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 plurality of transmission tones comprising a subset of data tones of a plurality of data tones and a subset of peak reduction tones (PRTs) of a plurality of PRTs, wherein the resource allocation indicates locations for the plurality of data tones and locations for the plurality of PRTs within a particular bandwidth, wherein the locations for the plurality of PRTs are arranged relative to the locations for the plurality of data tones according to a PRT subsequence of a universal PRT sequence, and wherein the PRT subsequence corresponds to a sub-band of the particular bandwidth; and transmit a data transmission using a waveform based at least in part on the resource allocation. Numerous other aspects are provided.

Abstract: Aspects described herein relate to physical downlink control channel (PDCCH) limits for multiple cells scheduling one cell in fifth generation new radio (5G NR). In an example, the aspects may include determining a PDCCH limit corresponding to at least one of a number of blind detections (BDs) and a number of control channel elements (CCEs) used for decoding PDCCH candidates for a first cell that schedules a second cell, and at least a third cell that schedules the second cell, wherein the third cell is the same cell as the second cell or the third cell is different from the second cell; and receiving one or more PDCCH transmissions from the first cell and the third cell based on the PDCCH limit.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) engaged in a positioning session with a transmission-reception point (TRP) receives, during a first state, a configuration of one or more sounding reference signal (SRS) resources, receives a first association between at least one SRS resource of the one or more SRS resources and at least one random access channel (RACH) resource of one or more RACH resources, switches out of the first state during an ongoing positioning session, and transmits, while outside the first state, at least a first signal of a RACH procedure to the TRP using transmission properties based on the first association between the at least one SRS resource and the at least one RACH resource.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may determine that a serving base station supports multi-code and single-code transmissions, receiving a scheduling message having a cyclic redundancy check scrambled with a radio network temporary identifier (RNTI), determine resources for communicating with the serving base station based on the scheduling message, and communicate on the resources using coding associated with the single-code transmissions. A base station may identify at least one user equipment that supports single-code transmissions, transmit a scheduling message having a cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI), wherein the scheduling message schedules the at least one user equipment for communication on resources using coding associated with the single-code transmissions and communicate with the at least one user equipment on the resources using the coding.
