Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a first transmit receive point in a multi-TRP configuration, a downlink control information (DCI) communication. The UE may identify one or more quasi-co-location (QCL) relationships associated with a control resource set (CORESET) or a search space set in which the DCI communication is received. A QCL relationship, of the one or more QCL relationships, is associated with one or more physical downlink shared channel (PDSCH) layers that are transmitted from a second TRP in the multi-TRP configuration. Numerous other aspects are provided.

Abstract: A base station may configure at least a first downlink transmission in a regular downlink burst with the first numerology for transmitting at least a portion of a data channel to a UE according to a numerology of a service used for data channel transmission. The base station also may configure at least a portion of a second downlink transmission in a regular downlink burst with a second numerology for transmitting a synchronization signal to the UE. A UE that receives the downlink regular burst may demodulate and decode the symbols in the received transmissions according to the numerology associated with each symbol.

Abstract: Aspects directed towards a frame-based equipment (FBE) design for a multi-operator New Radio shared spectrum (NR-SS) are disclosed. In one example, at least one contention slot is monitored within a fixed frame period of an unlicensed spectrum, and a determination is performed of whether a channel reservation signal associated with a higher priority node has been detected within the at least one contention slot. For this example, the at least one contention slot is associated with a resource of a subsequent fixed frame period of the unlicensed spectrum. A determination is then made of whether to transmit communication via the resource. Here, the communication is transmitted via the resource, if the channel reservation signal is not detected, and the communication is not transmitted via the resource, if the channel reservation signal is detected.
