    Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

    Abstract: Various aspects described herein relate to techniques for random access based on scalable signature design in wireless communications systems. A method, a computer-readable medium, and an apparatus are provided. In an aspect, the method may include randomly choosing an array of source symbols, wherein the array has one or more scalable dimensions based on at least one of a capacity requirement or a coverage requirement of a random access channel (RACH), encoding the array of source symbols into a codeword for a RACH signature, mapping the codeword to a serial concatenation of orthogonal or quasi-orthogonal sequences to define the RACH signature, and transmitting the RACH signature within a RACH slot. The techniques described herein may apply to different communications technologies, including 5th Generation (5G) New Radio (NR) communications technology.

    Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may obtaining channel access after a clear channel assessment (CCA) operation. The transmitting device may then determine an offset between a boundary of a symbol and a particular time at which the channel access is obtained. The transmitting device may generate a channel reservation (CR) preamble based on the offset and transmit the CR preamble. The transmitting device may also generate the CR preamble based on occupancy of sub-bands or beams used by the transmitting device. A receiving device may monitor for a CR message based on the CR preamble.

    Abstract: In order to maintain flexible system bandwidth and a flexible center frequency, without requiring a cyclic prefix or guard interval, a transmitter apparatus transmits a reference signal based on a single carrier waveform having a mixed symbol structure, in reference signal symbols using at least one of a cyclic prefix and a guard interval and transmits data based on the single carrier waveform without the cyclic prefix or the guard interval. The data may be based on input data processed using overlapping FFT windows, and an amount of overlap between the FFT windows may be configurable by the transmitter or the receiver. An apparatus receiving the downlink transmission comprising data based on a single carrier waveform may process the data based on overlapping FFT windows.

    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: Disclosed are techniques for wireless communication. In an aspect, a network entity, such as a location server or base station, may determine a positioning reference signal (PRS) frequency hopping configuration that specifies a plurality of PRS hops within a PRS resource set, each PRS hop occupying a specified set of one or more contiguous physical resource blocks, and further specifying a time gap between PRS hops to allow a sufficient retuning gap for a user equipment (UE) with reduced BW capability and/or relaxed processing time. The network entity may transmit the PRS frequency hopping configuration to at least one UE, e.g., via broadcast, multicast, groupcast, or unicast over Uu or PC5 links. The pre-configured time gap between PRS hops allows a reduced capacity UE to retune its RF circuit and thus allow PRS measurements over a larger bandwidth than what the UE can support without frequency hopping.
