There is provided a method of transmitting downlink control-related information to a terminal in a wireless telecommunications system. The method comprises allocating downlink resources in a first set of resources for sending the downlink control-related information; determining that a further downlink transmission will be transmitted using at least part of the allocated downlink resources thereby identifying a collision between the downlink control-related information transmission and the further downlink transmission; upon identifying a collision, allocating a second set of resources for sending the downlink control-related information; and transmitting the downlink control-related information using at least the second set of resources.

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.

Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

A method of operating a communications device comprises: determining to transmit a first uplink signal comprising a first set of feedback indications in a first set of uplink resources; determining to transmit a second uplink signal comprising a second set of feedback indications in a second set of uplink resources; determining that the first set of uplink resources and the second set of uplink resources are located within a same time slot; transmitting only the second uplink signal instead of both of the first uplink signal and the second uplink signal, the second uplink signal comprising an indication of one or more of the first set of feedback indications; and determining that a downlink assignment index associated with the first set of feedback indications is reduced when the one or more of the first set of feedback indications are indicated within the second uplink signal.

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, systems, and devices for wireless communications are described for controlling multiplexing of a reference signal on an uplink shared channel (UL-SCH). In an implementation, a user equipment (UE) may time division multiplex (TDM) a demodulation reference signal (DMRS) with other signaling across symbol periods of one or more allocated resource blocks. The UE may map the DMRS to resource elements of one or more symbol periods within the allocated resource blocks. The UE may then map uplink control information (UCI) to one or more symbol periods different than the symbol periods of the DMRS mapping. In some cases, the DMRS, UCI, or both may be frequency interleaved with UL-SCH data for the allocated resource blocks. The UE may generate and transmit an uplink waveform for transmission within the allocated resources of the uplink shared channel.

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 method implemented by a user equipment (UE) in a communication network is provided. The method includes receiving, from a network node, a delay indicator that indicates a scheduling delay for Physical Downlink Shaved Channel, PDSCH, and the UE counts the scheduling delay for the PDSCH according to the received indicator.

Apparatuses, methods, and systems are disclosed for downlink assignments for downlink control channels. One method includes, in response to an assignment group comprising a first assignment: determining a first data channel allocation comprising resources allocated to a first data channel; determining a first DMRS symbol location associated with the first data channel based on the first assignment, a first set of OFDM symbols, and a second set of OFDM symbols; and decoding the first data channel. The method includes, in response to the assignment group comprising a second assignment: determining a second data channel allocation comprising resources allocated to a second data channel; determining a second DMRS symbol location associated with the second data channel based on the second assignment, the first set of OFDM symbols, and the second set of OFDM; and decoding the second data channel.

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. The wireless device may transmit the UCI via a second PUSCH of the plurality of PUSCHs in response to a failed listen-before-talk (LBT) procedure for the first PUSCH.
