Abstract: Wireless communications systems and methods related to coordinating shared radio resources for spectrum sharing are provided. A spectrum resource control unit allocates a first resource for exclusive access by a first network operating entity in a spectrum. The exclusive access is configured for at least one of a network information communication or a feedback communication. The spectrum resource control unit allocates a second resource in the spectrum for shared access by the first network operating entity and a second network operating entity. The shared access is configured for at least a downlink control information communication. The spectrum resource control unit transmits, to the first network operating entity and the second network operating entity, a configuration indicating the first resource allocated for exclusive access by the first network operating entity and the second resource allocated for shared access by the first network operating entity and the second network operating entity.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

Abstract: Indication of globally synchronous communications mode is disclosed. A first node may detect an indication signal transmitted by a second node at a synchronization boundary of a shared communication channel. The indication signal is configured to identify a first transmission synchronization mode of the second node. The first node may then adjust its communications configuration in response to the indication signal. In making such adjustments, the first node may either contend for communications on the shared communication channel using the first transmission synchronization mode or refrain from attempting the communications on the shared communication channel using a second transmission synchronization mode.

Abstract: Methods, systems, and devices for wireless communication are described. Discontinuous reception (DRX) operation may be configured differently on enhanced component carriers (eCCs) than on other component carriers, including a primary cell (PCell). In some cases, a user equipment (UE) may be configured with several different eCC DRX modes. An eCC DRX configuration may, for example, be coordinated with downlink (DL) transmission time interval (TTI) scheduling so each DRX ON duration may correspond to a DL burst duration of the corresponding eCC. The eCC DRX ON durations may also be scheduled according to hybrid automatic repeat request (HARQ) process scheduling. In some examples, eCC DRX ON durations may be based on listen-before-talk (LBT) procedures. In some cases, eCC DRX ON durations may be configured to contain an uplink (UL) burst to enable channel state information (CSI) reporting. The eCC DRX may also be configured to minimize interruption of the PCell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay may identify an operator, of a wireless network, that provides service on a first frequency band, and may transmit, to a user equipment and using a second frequency band associated with the relay, a communication that includes information associated with the operator of the wireless network and information indicating that the relay is capable of providing a layer 1 relay function, associated with the first frequency band, to the user equipment. In some aspects, the first frequency band and the second frequency band are on different frequencies. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a first signal; listen, after transmitting the first signal and during a listening interval, for a second signal from a user equipment (UE) affected by the first signal, the second signal being indicative of interference at the first UE; receive the second signal during the listening interval; and initiate an interference management procedure based on receipt of the second signal.

Abstract: Techniques are described for wireless communication. One method includes winning a contention for access to an unlicensed radio frequency spectrum band, transmitting a request message upon winning the contention for access to the unlicensed radio frequency spectrum band, and receiving a response message over the unlicensed radio frequency spectrum band. The request message is transmitted by a user equipment (UE) on an enhanced physical random access channel (ePRACH), to access a cell that operates in the unlicensed radio frequency spectrum band. The response message is received in response to transmitting the request message.

Abstract: New radio (NR) transmission opportunity (TxOP) structure having flexible starting points are disclosed for wireless communications. When a typical listen before talk (LBT) procedure is performed, the transmitting node will not know ahead of time when the LBT will pass and, thus, when data transmissions can start. NR systems may include a mini-slot design for accommodating transmission units smaller than a slot. Aspects of the present disclosure provide for flexibly increasing the number of potential starting transmission boundaries depending on when the LBT pass is detected. Alternative aspects of the present disclosure determine the potential starting transmission points using a mini-slot based design, a floating slot based design, or a punctured slot based design with a code block group (CBG) level retransmission mechanism.

Abstract: A method of wireless communication includes determining, by a communication device, a value of a counter associated with a listen-before-talk (LBT) operation. The method further includes, after determining the value of the counter and during a first portion of a deferral interval associated with the LBT operation, performing a first measurement of a particular duration to determine a first energy value. The method further includes, during a second portion of the deferral interval subsequent to the first portion, performing a second measurement of the particular duration to determine a second energy value. The method also includes determining whether to initiate a contention interval associated with the LBT operation based on the first energy value and further based on the second energy value.

Abstract: A method of wireless communication includes receiving, by a user equipment (UE) from a base station, a listen-before-talk (LBT) configuration message indicating whether category 2 (Cat2) LBT operations are enabled or disabled for the UE. The method further includes receiving, by the UE from the base station, a channel occupancy time (COT) message configuring the UE with a COT. The method further includes performing, by the UE, an LBT operation based on the LBT configuration message and based on the COT message.
