Abstract: Methods, systems, and devices for transmitting a positioning reference signal over a channel within a window including a set of positioning reference signal transmission opportunities. A device may identify the window and perform a channel access procedure to access the channel during the window. Based on performing the channel access procedure, the device may obtain access to the channel and determine that a portion of the positioning reference signal transmission opportunities are remaining within the window. The device may transmit a positioning reference signal during one or more of the remaining positioning reference signal transmission opportunities. In some cases, the device may refrain from transmitting a positioning reference signal during a portion of a positioning reference signal transmission opportunity even if the device gains access to the channel during that portion of the positioning reference signal transmission opportunity.

Abstract: Channel reservation systems and methods are disclosed herein, which schedule transmissions on a shared radio medium that is shared by a plurality of licensed network operators. In embodiments, priority access is pre-assigned to the network and the method determines whether to send a transmission based at least on the transmitter's priority class as compared to another transmitter's priority class and to which transmitter the time slot of a signal is dedicated. In embodiments, priority access may not be preassigned to the network and pre-grants may be used in conjunction with CR-Ts and CR-Rs to determine whether a transmitter transmits.

Abstract: Techniques are described for wireless communication. One method includes segmenting a payload into a plurality of code blocks; generating, for each code block, a cyclic redundancy check (CRC); encoding each code block and associated CRC in one or more codewords of a plurality of codewords; and transmitting the codewords. The encoding is based at least in part on a low density parity check code (LDPCC) encoding type. Another method includes receiving a plurality of codewords associated with a payload encoded using a LDPCC encoding type; decoding a set of the codewords associated with the first payload and a CRC; and transmitting one of an acknowledgement (ACK) or a non-acknowledgement (NAK) for the set of the codewords.

Abstract: Reference signal and transmitter (Tx)/receiver (Rx) precoding for user equipment (UE) multiplexing in new radio (NR) shared spectrum networks is discussed. In certain reference signals, a base station may schedule multiple UEs for transmission of uplink reference signals within an identified subframe. The base station may transmit a reference signal configuration message, wherein the reference signal configuration message includes a transmission sequence identifier identifying a multiplexing for antenna ports assigned for transmission of the uplink reference signals. The multiplexing may be one or both of frequency divisional multiplexing (FDM) and time division multiplexing (TDM) over the identified subframe. Additional reference signals, transmit precoders may be identified by the base station based on channel inversion calculations of the channel matrix determined based on uplink reference signals.

Abstract: Techniques for synchronization across transmitting nodes of a same public land mobile network (PLMN) operator using a shared radio frequency spectrum band may include initiating, at a first wireless node, a listen-before-talk (LBT) procedure for access to the shared radio frequency spectrum band, and identifying that a second wireless node associated with a same PLMN operator as the first wireless node has won contention for the shared radio frequency spectrum band. The first wireless node may discontinue the LBT procedure and initiate an auxiliary transmission using the shared radio frequency spectrum band concurrently with a primary transmission of the second wireless node.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit a first grant to a UE. The apparatus may determine whether an acknowledgment to the first grant is received. When the acknowledgment to the first grant fails to be received by the apparatus, the apparatus may transmit, to the UE, a second grant including information regarding the first grant. In another aspect, an apparatus may be a UE. The apparatus may receive a first grant. The first grant may include a first Mayday bit. The apparatus may receive a second grant. The second grant may include a TTI count corresponding to a number of unacknowledged TTIs. The second grant may further include a second Mayday bit. The apparatus may determine an acknowledgment based on the TTI count and the first and second Mayday bits.
