Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: Various aspects and features provide waveform design and signaling support that provide and facilitate high accuracy positioning determination by low powered devices (e.g. UEs) in NR and IoT by allowing UEs to request on demand positioning operation support from a base station and the base station to dynamically configure parameters associated with a positioning reference signal (PRS) for transmission to the UEs. A UE may transmit an indication of its positioning requirement and/or capability information to a base station. The base station may configure parameters associated with a positioning reference signal (PRS), for example, a waveform type of the PRS, based on the indication and transmit the PRS to the UE. The UE may receive the PRS having the configured parameters and may perform at least one of UE positioning, ranging, or a UE velocity determination based on the received PRS.

Abstract: Aspects of the disclosure relate to allocating resources for a physical uplink control channel (PUCCH). In a first example, a subset of a resource set corresponding to a PUCCH is identified based on an explicit mapping of acknowledgment resource indicator (ARI) values, and a resource index corresponding to a resource within the subset is derived based on an implicit mapping of the resource index. A PUCCH communication is then transmitted via the resource. In another example, a user equipment (UE) is configured to ascertain resources for a PUCCH in accordance with an explicit mapping of ARI values and an implicit mapping of a resource index such that the explicit mapping facilitates an identification of a subset of a resource set, whereas the implicit mapping facilitates a derivation of the resource index to identify a corresponding resource within the subset.

Abstract: In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes a timing value indicating a timing of an opportunity, subsequent to reception of the DCI, for transmission or reception of a communication corresponding to the DCI. The UE may determine an uplink opportunity or a downlink opportunity for transmission or reception of the communication based at least in part on the timing of the opportunity. A counter for determining the uplink opportunity may be incremented only for transmission time intervals (TTIs) in which the UE is allowed to transmit the communication in an uplink channel. A counter for determining the downlink opportunity may be incremented only for TTIs in which the UE can expect to receive the communication in a downlink channel. The UE may transmit or receive the communication in the uplink opportunity or the downlink opportunity. Other aspects are disclosed.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a UE. The apparatus may generate a reference signal using a base sequence obtained from a table for a first Radio Access Technology (RAT), the table including a plurality of base sequences that each have a cross-correlation value with a set of base sequences associated with a second RAT. Then, the apparatus transmits the reference signal to a base station. The reference signal may be multiplexed with a data transmission.

Abstract: A configurable new radio (NR) uplink (UL) transmission may use transmit diversity. A user equipment (UE) may identify an uplink transmission of at least one stream as using one of cyclic prefix orthogonal frequency division multiplexing or discrete Fourier transform spread orthogonal frequency division multiplexing. The UE may apply a precoding matrix to the at least one identified stream. The precoding matrix changes over time. The precoding matrix may change based on closed loop feedback, a precoding cycling pattern, and/or a code division multiplexing group. The UE may transmit the at least one identified stream from multiple antennas according to the applied precoding matrix.
