The disclosure reduces requirements on a buffer and reduces complexity.

This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for terminating HARQ retransmissions. A wireless receiver may determine that a transmission of a first TB based on a first redundancy version is not received from a wireless transmitter. Based on the determination, the wireless receiver may transmit, to the wireless transmitter, a HARQ ACK to terminate one or more HARQ retransmissions associated with the different redundancy versions of the first TB.

A user equipment for a mobile telecommunications system has circuitry configured to communicate with at least one base station, wherein the circuitry is further configured to: interrupt processing of a lower priority data transmission when a higher priority data transmission has to be processed, when it is determined that an available processing power is below a predetermined threshold.

A user equipment (UE) can include processing circuitry configured to decode downlink control information (DCI) from a base station, the DCI including a modulation coding scheme (MCS) index and physical uplink shared channel (PUSCH) allocation. A demodulation reference signal (DMRS) is encoded for transmission to the base station within a plurality of DMRS symbols based on the PUSCH allocation. A phase tracking reference signal (PT-RS) time domain density is determined based on the MCS index and a number count of the DM-RS symbols for the DM-RS transmission. The PTRS is encoded for transmission using a plurality of PT-RS symbols based on the determined time domain density. The plurality of symbols includes one or both of front-loaded DM-RS symbols and additional DM-RS symbols.

In order for a first terminal apparatus to transmit a physical uplink control channel to a base station without retuning regardless of a bandwidth part used by the first terminal apparatus, a base station 100 according to the present disclosure includes a communication processing unit 141 configured to communicate with the first terminal apparatus (terminal apparatus 200A) within a bandwidth part of an uplink system band, the bandwidth part being used by the first terminal apparatus (terminal apparatus 200A), wherein the bandwidth part includes a physical uplink control channel region used by the first terminal apparatus (terminal apparatus 200A).

Methods and apparatuses in a wireless communication system. A method of operating a UE includes: receiving configuration information for TX resource pools including at least one of a first set of resource pools or a second set of resource pools; identifying, at an RRC sub-layer, the first and second set of resource pools based on a HARQ feedback channel; selecting, at a MAC sub-layer, a logical channel to transmit SL data, wherein the logical channel includes a highest priority among multiple logical channels using an LCP function; determining, at the MAC sub-layer, whether the logical channel is configured with the HARQ feedback channel; selecting, at the MAC sub-layer, a TX resource pool from the first set of resource pools based on a determination that the logical channel is configured with the HARQ feedback channel; and transmitting the SL data based on the TX resource pool.

A wireless device receives a radio resource control (RRC) message that includes configuration parameters for scheduling a plurality of physical uplink shared channels (PUSCHs) via a downlink control information (DCI). In an embodiment, the configuration parameters may include an indication enabling a dynamic determination of a PUSCH of the plurality of PUSCHs for multiplexing an uplink control information (UCI). In an additional embodiment, the UCI may overlap with a first PUSCH of the plurality of PUSCHs.
