摘要： Apparatus, methods, and computer-readable media for coexistence of multiple uplink control channel formats for wireless communication with power spectral density limitation are disclosed herein. A user equipment (UE) may communicate, with a base station (BS) over a random access channel on a first set of random access resources or a second set of random access resources, a random access request based on a comparison between an intended transmit power of the random access request and a reference transmit power threshold. The UE may communicate, on a first set of uplink resources, a control message for initial network access when the random access request is communicated on the first set of random access resources. The UE also may communicate, on a second set of uplink resources, the control message when the random access request is communicated on the second set of random access resources.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indication of a time gap value associated with a random access channel (RACH) procedure, wherein the time gap value is based at least in part on a capability of the base station, determine whether a physical RACH (PRACH) occasion associated with the RACH procedure is valid based at least in part on receiving the indication of the time gap value associated with the RACH procedure, and selectively transmit, to the base station, a PRACH transmission in the PRACH occasion based at least in part on determining whether the PRACH occasion is valid. Numerous other aspects are provided.

摘要： Certain aspects of the present disclosure provide techniques for demodulation reference signal (DMRS) sequence selection. One aspect provides a method for wireless communication by a first wireless node. The method generally includes selecting a type of DMRS sequence to be used for communication with a second wireless node based on a signal quality associated with the communication, receiving a message having the type of DMRS sequence, and performing channel estimation based on the DMRS sequence using the message.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may process, for a physical uplink control channel (PUCCH) communication in a millimeter wave (mmWave) band, information for transmission, wherein the information is modulated using an extended sequence with a length greater than a base sequence length for PUCCH communication or wherein a cyclic shift, of a plurality of cyclic shifts for a set of contiguous resource blocks for transmission of the information, is applied to the information based at least in part on a resource block group associated with the information. The UE may transmit the information based at least in part on processing the information. Numerous other aspects are described.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may receive, from a base station via a DCI message, an indication of at least one K1 value corresponding to a plurality of physical downlink shared channel (PDSCH) transmissions over a plurality of PDSCH resources. The DCI message may comprise scheduling information for the plurality of PDSCH transmissions. The at least one K1 value may be associated with at least one physical uplink control channel (PUCCH) resource and indicative of a PDSCH-to-hybrid automatic repeat request (HARQ) timing. The apparatus may transmit, to the base station via the at least one PUCCH resource, at least one acknowledgment/negative-acknowledgment (ACK/NACK) indication associated with the at least one K1 value and corresponding to the plurality of PDSCH resources.
