Abstract: Aspects directed towards facilitating multi-node listen before talk (LBT) functionality via a centralized controller are disclosed. In one example, for each of a plurality of scheduled entities, a corresponding set of scheduling entities is identified, and each scheduling entity of the set of scheduling entities is instructed to perform at least one LBT evaluation. This example then further includes controlling whether any of the plurality of scheduled entities is served by a corresponding one or more scheduling entities of the set of scheduling entities based on the at least one LBT evaluation performed by each scheduling entity.

Abstract: Sharing between priority access license (PAL) and general authorized access (GAA) communications in 5G new radio (NR) systems in 3.5 GHz Spectrum Access System (SAS)/License Shared Access (LSA) operations is disclosed. A resource configuration may be defined that identifies a plurality of sound reference signal (SRS) resources including at least a sounding set of SRS resources and a coexistence set of SRS resources. When communication may occur between PAL entities, a base station transmits a trigger signal to a served UE. The UE transmits an SRS in response to the trigger signal using the coexistence set of SRS resources. The SRS over the coexistence set of resources may reserve communication on the shared communication channel.

Abstract: Certain aspects of the present disclosure provide techniques for beam refinement reference signal (BRRS) design for millimeter wave (mmWave) system in shared spectrum. The techniques can include a method for wireless communication that includes transmitting at least one of a request-to-send (RTS) or a clear-to-send (CTS) within a frame using frequency resources in a shared spectrum, and including a beam refinement reference signal (BRRS) in the at least one of the RTS or CTS.

Abstract: Wireless communications systems and methods related to providing frequency diversity for communications in an unlicensed spectrum are provided. A first wireless communication device communicates, with a second wireless communication device, an opportunistic frequency- switching configuration for a first frequency band and a second frequency band. The first frequency band and the second frequency band are shared by a first network operating entity and a second network operating entity. The first wireless communication device communicates, with the second wireless communication device, a first communication signal in a first frequency band based on the opportunistic frequency- switching configuration. The first wireless communication device switches from the first frequency band to a second frequency band based on the opportunistic frequency- switching configuration. The first wireless communication device communicates, with the second wireless communication device after the switching, a second communication signal in the second frequency band based on the opportunistic frequency- switching configuration.

Abstract: Methods, systems, and devices for wireless communications, and more particularly for facilitating autonomous uplink transmission (AUL) using shared (e.g., in a synchronized manner among one or more operators) radio frequency spectrum are described. In aspects, a method of wireless communication over a shared medium may include determining, by at least one user equipment (UE) served by a base station associated with a first operator, access is obtained to the shared medium for a transmission opportunity (TXOP) by the base station based on autonomous uplink resources in the TXOP allocated to at least one UE served by the base station and/or an indication from the at least one UE of autonomous uplink data, and transmitting the autonomous uplink data from the at least one UE to the base station.

Abstract: Certain aspects of the present disclosure provide techniques for rate-matching data on a per transmission reception point (TRP) basis for single downlink control information (DCI) multi-TRP transmissions. Transmitters operating according to the present disclosure use a per TRP rate matching technique in which the rate-matching order is to first rate-match across spatial layers transmitted by a TRP, then across frequency, then across time, and then to another TRP, where remaining data is ratematched across the spatial layers of that other TRP, then across frequency, and then across time. The described per TRP rate-matching technique causes code blocks of a transport block to be transmitted by one TRP, instead of each code block being transmitted by a group of TRPs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a transmission detection procedure on each base station before combining control information. The UE may use demodulation reference signals (DMRS) as a detection mechanism. If the UE detects a DMRS from a base station, the UE may determine that a control resource set associated with the base station is valid for combining. If the UE does not detect DMRS from the base station, the UE may refrain from combining control information from the base station. In another example, base stations that pass a listen-before-talk (LBT) pr6ocedure may transmit a preamble before transmitting control information. A preamble may carry a preamble sequence associated with a specific control resource set. The UE may identify a preamble sequence and determine that the corresponding control resource set is valid for control information combining.
