Abstract: A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time-frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described in which a UE may determine a time duration of a transmission gap between a random access preamble and random access payload. The time duration of the transmission gap may be based on a configuration of the random access channel resources, a timing adjustment (e.g., an estimated propagation delay) for uplink transmissions from the UE, a beam management procedure at the UE and/or the base station, or combinations thereof. The UE may select an initial transmission gap duration based on the configuration of the random access channel resources, and may adjust the initial transmission gap duration based on the timing adjustment. Multiple UEs may be configured such that random access channel transmissions align with a random access occasion (RO) window. A base station may decode messages from multiple UEs using joint or successive decoding to recover the corresponding random access messages.

Abstract: Aspects of the present disclosure provide techniques and apparatus for wireless communication. In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE) in a network supporting co-existence of a first type of random access and a second type of random access, which may be associated with different latency, overhead, quality of service (QoS), energy efficiency, and/or spectral efficiency.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may construct, for adjusted fractally enhanced kernel (FRANK) polar coding, encoding code for encoding data of an ultra-reliable low latency (URLLC) communication, wherein an information bit assignment to an information bit set associated with the encoding code is performed based at least in part on an adjusted dimensionality factor, wherein the encoding code is all-stage FRANK polar code or partial-stage FRANK polar code, and wherein the encoding code is constructed for code block shortening or code block puncturing. In some aspects, the user equipment may transmit the URLLC communication encoded using the encoding code based at least in part on the information bit assignment to the information bit set. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for short uplink burst designs. In some cases, one sequence, from a plurality of sequences, may be transmitted in multiple tones of at least one short burst symbol conveying at least one bit of information. The plurality of sequences may have the same values at a first set of common tone locations for demodulation reference signals (DMRS) and groups of sequences from the plurality of sequences may be identified, each sequence in a group having a second set of common tone locations for DMRS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine information that identifies a resource for transmitting an acknowledgment of a message associated with a random access procedure. The information that identifies the resource may be determined based at least in part on at least one of: a frequency band associated with the random access procedure, a resource associated with at least one message in a sequence of messages associated with the random access procedure, a payload of at least one message in the sequence of messages associated with the random access procedure, or a grant associated with another message in the sequence of messages associated with the random access procedure. In some aspects, the user equipment may transmit the acknowledgment based at least in part on the information that identifies the resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices are described for wireless communications. A wireless device may receive an allocation of uplink resources for an uplink transmission of uplink control information (UCI) during a long physical uplink control channel (PUCCH), which may range from four to fourteen symbol periods in length. The wireless device may identify a frequency hopping location based on the length of the PUCCH and a number of bits used to represent the UCI. In some cases, the frequency hopping location partitions the long PUCCH into a first set of symbol periods and a second set of symbol periods. After identifying the frequency hopping location, the wireless device may transmit a UCI message, which may include information and reference symbols, over a first frequency bandwidth during the first set of symbol periods and over a second frequency bandwidth during the second set of symbol periods.
