Terminal device, telecommunications apparatus and methods
A method of transmitting data by a terminal device operating in a wireless communications system comprising a non-terrestrial network access node and the terminal device, comprises the terminal device receiving an indication of an initial value of a set of one or more communications parameters for transmitting radio signals carrying the data, and modelling a state of a communications channel from the terminal device to a non-terrestrial network access node, in which a link adaptation procedure is used to select a revised value of the set of the one or more communications parameters with respect to the initial value of the set of the one or more communications parameters for the modelled channel state, and the method includes adapting the value of the set of the one or more communications parameters according to the revised value.
Power control for shared feedback
Methods, systems, and devices for wireless communications are described. A base station may communicate with a user equipment (UE) or multiple UEs using multicast transmissions, and each of the multiple UEs may use shared resources to transmit feedback. A UE may receive a power control configuration associated with multicast communications and indicating one or more control parameters or weighting factors for uplink feedback. The UE may monitor a set of downlink resources for the multicast message from the base station, and may determine a decoding failure for the multicast message. The UE may determine whether to transmit uplink feedback to the base station based on the received power control parameters, such as adjusting UE transmit power using a weighting factor or other power control parameters. The UE may determine whether to transmit the uplink feedback message indicating the decoding failure based on the power control configuration.

METHODS TO REDUCE FRONTHAUL COMPLEXITY FOR SINGLE FREQUENCY NETWORK (SFN) IN AN OPEN RADIO ACCESS NETWORK (O-RAN)
An Open Radio Access Network (O-RAN) system including a single frequency network (SFN) for handling signal transmissions involving a user equipment (UE) is provided, which system includes: a plurality of O-RAN radio units (O-RUs) configured to simultaneously send the same signal over the same frequency channel; and an O-RAN distributed unit (O-DU). The system is configured to filter out at least one of uplink (UL) and downlink (DL) signals associated with at least one of the plurality of O-RUs in the SFN based on one of signal power or signal-to-noise ratio (SNR). Signal paths of the O-RUs toward the O-DU are linked directly to the O-DU, and each of the O-RUs filters one of UL and DL signals based on a comparison to a predetermined signal power or SNR threshold. The O-DU controls DL transmission to only use the O-RUs whose UL signals were above the predetermined threshold.
