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.

HARQ retransmission termination based on lost redundancy version

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.

USER TERMINAL CONFIGURED FOR OPERATION BASED ON PERSISTENT RESOURCE ALLOCATION INFORMATION
20230239849 · 2023-07-27 · ·

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.

20230006801 · 2023-01-05 ·

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.
