Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., new radio (NR) wireless communications systems), a base station may serve a large number of user equipment (UEs). The base station may allocate uplink control channel resources to the UEs. A UE may receive, from the base station, a first resource assignment for a first set of symbols. The UE may also receive, from the base station, a second resource assignment for a second set of symbols, where the first set of symbols and the second set of symbols include an overlapping set of symbols. The UE may modify first resources for the first resource assignment, second resources for the second resource assignment, or both. The UE may then transmit first information based on the first resource assignment.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user terminal may communicate via a relaying satellite in a non-terrestrial network. The non-terrestrial network may cause communication disruptions in hybrid automatic repeat request (HARQ) processes due to communication delays. Base stations and user terminals communicating via a satellite may implement dynamically configurable HARQ processes to avoid latency in a wireless communications system.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may broadcast a synchronization signal using a narrowband portion of a bandwidth of a cell. The synchronization signal may include a sequence repeated over several symbol periods using a cover code to support power-efficient cell acquisition. A user equipment (UE) receiving the synchronization signal may determine frequency and timing information for a cell by performing a weighted combination and accumulation of low complexity autocorrelation and cross-correlation procedures on the synchronization signal. The reduced complexity correlation procedures may be enabled based on the use of the cover code and a base sequence. In some cases, the cross-correlation may be performed at multiple sampling rates. The use of the cover code within the synchronization signal may also support correlation procedures that use recursive or repeated updates, which may allow for further reduced computational complexity relative to other cell search procedures.
