Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may perform a first encoding operation on source packets that generates a first set of network coding encoded packets and may broadcast the first set of network coding encoded packets for reception by a plurality of receivers. The transmitter may receive feedback information associated with the first set of network coding encoded packets, the feedback information indicating that a first subset of network coding encoded packets were received by at least one of the plurality of receivers, the feedback information further indicating that one or more receivers of the plurality of receivers did not successfully recover all of the plurality of source packets. The transmitter may broadcast a second set of network coding encoded packets that does not include any of the first subset of network coding encoded packets. Numerous other aspects are provided.

Abstract: A user equipment (UE) and a base station may perform a random access procedure based on a dynamic physical random access channel (PRACH) configuration. The UE may determine a first PRACH configuration, for example, based on system information. The UE may determine a second PRACH configuration, for example, based on a dynamic configuration message. The UE may determine to follow the second PRACH configuration based on a current time or the dynamic configuration message. The UE may transmit a first message of a random access (RACH) procedure based on the second PRACH configuration.

Abstract: This disclosure provides systems, methods, and apparatuses for supporting network transmissions using unicast sidelink communications. A base station (BS) may transmit a set of encoded packets to a number of user equipment (UEs) and receive feedback messages from the UEs that indicate sets of decoded packets. Based on the feedback messages, the BS may transmit an updated set of encoded packets based on a difference between the set of encoded packets and the union of decoded packets. The BS may transmit an instruction to a first UE to transmit a unicast sidelink communication to a second UE that includes a set of missed packets that includes one or more decoded packets that were decoded by the first UE but were not decoded by the second UE. The first UE may transmit the unicast sidelink communication to the second UE.

Abstract: A method of wireless communication by a user equipment (UE) comprises receiving, from a base station, multiple reference signals, and estimating a channel based on the received reference signals. The channel comprises multiple channel paths. The method also includes quantizing an angle of arrival (AoA) of each channel path into one of a group of quantization levels. The method further includes reporting to the base station the quantized angle of arrival, and also a delay and/or power level for the quantized angle of arrival.

Abstract: Techniques and apparatus for avoiding hybrid automatic repeat request (HARQ) process identifier (ID) conflicts in scenarios where multiple semi persistently scheduled (SPS) configurations share the same pool of HARQ process IDs are provided. One technique involves receiving an indication of SPS configurations, where each SPS configuration allocates a set of SPS occasions for physical downlink shared channel (PDSCH) transmissions. A conflict is detected between a first HARQ process ID associated with a first SPS occasion of a first SPS configuration and a second HARQ process ID associated with a second SPS occasion of a second SPS configuration, where the first SPS occasion occurs prior to the second SPS occasion. At least one action to resolve the conflict is taken based on predetermined rule(s), in response to detecting the conflict.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by base station. The method generally includes transmitting, to a user-equipment (UE), a packet indicating a beam switch associated with communication with the UE, receiving an acknowledgment (ACK) message, detecting that the ACK message is configured to indicate whether parsing of contents of the packet was successful, determining a timing of the beam switch based on the detection, and performing the beam switch in accordance with the determination of the timing.

Abstract: A configuration for a wireless device to perform iterations of SIM to detect clutter echo in order to improve a configuration for SIM. The apparatus performs a SIM for multiple beam pairs based on a first transmission power. The apparatus performs an iteration of the SIM for one or more beam pairs that meet a criteria. The iteration of the SIM is based on a second transmission power. The second transmission power is greater than the first transmission power.

Abstract: A method comprises: selecting, from a first number of first receive (RX) beams having a first beam width, a first RX beam to form a first beam-pair with a first transmit (TX) beam from one or more base stations, the selection being based on a first measurement of a first reference signal received by the UE using the first beam-pair; selecting, from a second number of second RX beams having a second beam width, a second RX beam to form a second beam-pair with the first TX beam, the selection being based on a second measurement of a second reference signal received by the UE using the second beam-pair, the second number of second RX beams being smaller than the first number of first RX beams, the second beam width being narrower than the first beam width; and performing a location estimate operation using either the second beam-pair, or a third beam-pair derived from the second beam-pair.

Abstract: Aspects of the present disclosure generally relate to methods and apparatus for encoding repetitions of a physical uplink control channel (PUCCH). In some aspects, the disclosed methods or techniques include first determining that a first number of REs of a first PUCCH repetition used for UCI transmission is different than a second number of REs of a second PUCCH repetition used for the UCI transmission. Based on the determination, the UE performs one or more actions to provide a same mother polar code length for generating coded bits for each of the first and second PUCCH repetitions. The UE performs polar code encoding of information bits of the UCI for the first PUCCH repetition and the second PUCCH repetition based on the same mother polar code length. The UE transmits the first and the second PUCCH repetitions including the respective polar-encoded UCI.
