Abstract: A method for data retransmission and related devices are provided. The method includes the following. A first device receives first information from a second device, where the first information includes a hybrid automatic repeat request (HARQ) feedback indication. If the HARQ feedback indication is HARQ feedback enabled, the first device monitors data retransmission of the second device within a duration of a first retransmission timer. If the HARQ feedback indication is HARQ feedback disabled, the first device monitors the data retransmission of the second device within a duration of a second retransmission timer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive at least one channel repetition of a plurality of channel repetitions, wherein the at least one channel repetition comprises an indication associated with a beam parameter. The wireless communication device may perform a wireless communication action based at least in part on a determination associated with the beam parameter, wherein the determination associated with the beam parameter is based at least in part on an identification of a reference repetition occasion of a plurality of repetition occasions corresponding to the plurality of channel repetitions. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a random access channel preamble to abase station. The UE may receive, from the base station and in response to the random access channel preamble, a grant comprising a first frequency hopping indication associated with intra-slot frequency hopping and a second frequency hopping indication associated with inter-slot frequency hopping. The UE may identify, based at least in part on the first frequency hopping indication or the second frequency hopping indication, a frequency hopping configuration for transmission of repetitions of an uplink transmission responsive to the grant. The UE may transmit the repetitions of the uplink transmission using one or more frequency Chops in accordance with the frequency hopping configuration.

Abstract: An apparatus for wireless communication is provided. The apparatus may be a network node. The apparatus receives a set of uplink transmissions from a set of user equipments (UEs) via a first resource of a non-orthogonal channel, wherein the apparatus is unable to decode the set of uplink transmissions. The apparatus transmits a retransmission request to a subset of the set of UEs. The apparatus receives a retransmission of a first uplink transmission in the set of uplink transmissions via a second resource of the non-orthogonal channel in response to the retransmission request. The apparatus decodes a second uplink transmission in the set of uplink transmissions based on at least the retransmission of the first uplink transmission.

An example method may include receiving, from a second network entity, downlink control information (DCI) scheduling a physical uplink shared channel (PUSCH) transmission, where the PUSCH transmission includes a first portion associated with a first subset of layers within a set of layers and a second portion associated with a second subset of layers within the set of layers. The example method may further include mapping at least one transport block (TB) or codeword (CW) to the first portion or the second portion based on the DCI or a radio resource control (RRC) configuration. The example method may further include transmitting the at least one TB or CW to the second network entity.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of retransmission of sidelink positioning reference signal (PRS). The method comprises transmitting, to a second device, a first sidelink reference signal associated with a positioning or ranging procedure of the first device; and receiving, from the second device, a second sidelink reference signal associated with the positioning or ranging procedure, the second sidelink reference signal comprising information indicating whether the first sidelink reference signal needs to be retransmitted. In this way, the retransmission of the sidelink PRS can be triggered without extra resource consumption and a fast RTT estimation for sidelink ranging and positioning can be achieved.
