Abstract: Certain aspects of the present disclosure relate to techniques for configuring an adaptive frame structure for wireless communications systems using unlicensed radio frequency spectrum. A base station (BS) may determine whether another device is transmitting on a channel in the unlicensed radio frequency spectrum or one or more other network conditions pertaining to the channel, determine a frame structure from a plurality of frame structures used for data communications based at least in part on the one or more network conditions, wherein each of the plurality of frame structures has a different frame duration, and communicate with a user equipment (UE) using the determined frame structure. A UE may determine a frame structure from a plurality of frame structures used for data communications, wherein each of the plurality of frame structures has a different frame duration, and communicate with a BS using the determined frame structure.

Abstract: Methods and apparatuses for wireless communications are described. The aspects relate to a frame structure for new radio shared spectrum. For instance, the frame structure may provide shared medium access by multiple operators in a new radio shared spectrum system. Specifically, the present aspects provide for utilizing reservation preambles associated with a distinct operator for announcing to other operators a reservation of at least one transmission opportunity of a given frame in the new radio shared spectrum.

Abstract: Techniques for spectrum sharing among operators are provided. A base station (BS) licensed to a first operator monitors, while operating on a first carrier frequency assigned to the first operator, a reservation period on a second carrier frequency assigned to a second operator that shares spectrum with the first operator. The BS determines, based on the monitoring, availability of the second carrier frequency for use by the BS during at least one subsequent data period. The BS determines whether to attempt to reserve access on the second carrier frequency for use during the at least one subsequent data period based on the determined availability.

Abstract: Certain aspects of the present disclosure provide techniques for protecting overhead and common channel transmissions in a NR shared spectrum system. A BS of a first operator may receive information regarding at least one overhead transmission associated with a wireless device of a second operator and may protect one or more overhead signal transmissions of the wireless device based, at least in part, on the received information. A UE may detect information associated with at least one overhead transmission from a wireless device associated with a first operator and may transmit the information regarding the detected overhead transmission to a BS associated with a second operator. A UE served by a BS associated with a first operator may detect a wireless device (e.g., another UE or a BS) associated with a second operator. The UE may report an identification of the wireless device to the BS.

Abstract: The present methods and apparatus enable transmission of an interlaced reference signal for two UEs using a comb structure. In some aspects, the present methods and apparatus may allocate resources and indicate whether a first UE and a second UE are to transmit DM-RS with a comb structure in a single slot based on the allocation. Further, in some aspects, the present methods and apparatus may allocate resources and transmit information indicating whether a first UE is to transmit DM-RS in a first slot or in both a first slot and a second slot within a subframe.

Abstract: A method, an apparatus, and a computer-readable medium for delivering content to end user via shared broadcast are provided. The apparatus may be a UE that determines to acquire a MBMS service. The UE tunes to a frequency provided by a first MNO to which the UE is not a subscriber in order to receive the MBMS service via a carrier shared by the first MNO and at least one other MNO. The UE receives the MBMS service on the frequency via the carrier shared by the first MNO and the at least one other MNO. The shared carrier may have a common SFN timing with respect to the first MNO and the at least one other MNO. The shared carrier may include a shared MBMS SDL carrier. The shared carrier may include a standalone shared carrier for receiving the MBMS service and control information associated with the MBMS service.
