Abstract: Methods and devices for downlink (DL) control channel communications operating in a semi-static channel access mode in a shared frequency band are provided. In one aspect, a method is performed by a base station (BS) and includes: transmitting, based on a first configuration during a first period, a first downlink (DL) control signal, where the first configuration is based on the first period associated with a first channel occupancy signal (COT) type; and transmitting, based on a second configuration during a second period, a second DL control signal, where the second configuration is based on the second period associated with a second COT type different from the first COT type, and where the second configuration is different from the first configuration.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of multiple sets of linked physical downlink control channel (PDCCH) candidates if some PDCCH candidates of the multiple sets of linked PDCCH candidates occupy a same set of resources. In one aspect, the UE may select to monitor one of the PDCCH candidates that occupy the same set of resources in accordance with a prioritization rule. Upon selecting one of the PDCCH candidates that occupy the same set of resources for monitoring by the UE, the UE and the component of the BS may select a reference PDCCH candidate for one or more of the multiple sets of PDCCH candidates in accordance with a reference selection rule.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may add a first extension before modulated symbols of a communication, the first extension including data from an end portion of the modulated symbols. The transmitting device may add a second extension after the modulated symbols, the second extension including data from a beginning portion of the modulated symbols. The transmitting device may apply a first weighting function that overlaps the first extension and the beginning portion of the modulated symbols. The transmitting device may apply a second weighting function that overlaps the end portion of the modulated symbols and the second extension. The transmitting device may add one or more of a header before the first extension or a tail after the second extension. The transmitting device may transmit the communication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described for improving sidelink communication reliability. In some examples, a user equipment (UE) may map allocated sidelink resources from a logical domain to a physical domain, where the mapped resources may include greater frequency diversity in the physical domain A frequency range of a sidelink control channel or of a sidelink data channel may be greater in the physical domain than in the logical domain after the mapping. In some examples, sidelink communications may be associated with an aggregation factor that represents a number of repetitions of a sidelink communication. In this example, a UE may repeat a sidelink communication within a contention-based resource pool a number of times before receiving feedback in order to increase communication reliability. A first UE may communicate a sidelink communication with a second UE using a resource mapping or repetitions of the sidelink communication.

Abstract: This disclosure provides systems, methods and apparatuses for uplink channel transmission for multiple transmit receive points (TRPs). In one aspect, a user equipment (UE) resolves overlapping physical uplink control channels (PUCCHs) in a slot or overlapping PUCCH(s) and PUSCH(s) that are mapped to a same TRP in a multi-TRP scenario and that are mapped to two or more different TRPs in the multi-TRP scenario. For example, in a multi-TRP scenario that includes two TRPs, the UE may eliminate overlap of these uplink channels for each of the two TRPs individually and may additionally eliminate overlap of these uplink channels between the two TRPs.
