Abstract: A wireless node configured to communicate with a remote node using a timeslot structure. The timeslot structure includes a plurality of data channels and a plurality of control channels, wherein each of the control channels comprises a plurality of control units. The wireless node is further configured to assign any one of a plurality of control messages for the data channels to any one of the control units.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method for wireless communication includes determining, by a user equipment (UE), listen before talk (LBT) information associated with new radio-unlicensed (NR-U) operation of the UE. The method further includes transmitting, by the UE, areport including the LBT information. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide a base station receiving an indication from a core network to serve multicast/broadcast traffic to one or more UEs. The base station may select a radio bearer mode from a plurality of radio bearer modes for delivery of the multicast/broadcast traffic to at least one UE of the one or more UEs. For example, the base station may select a multicast/broadcast only mode, a mixed multicast/broadcast mode and unicast mode, or a unicast mode for service of the traffic. Dependent on the selected mode and/or quality of service, the base station may select a dedicated radio bearer (DRB) for communication of the traffic in a unicast mode (e.g., to a particular UE) or a multicast radio bearer (MRB) for communication of the traffic in a broadcast/multicast mode.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may employ joint paging techniques. Multiple base stations may coordinate to determine joint paging parameters for a joint paging area. Each base station in the joint paging area may use the same paging parameters to generate the same joint paging message. The base stations in the joint paging area may communicate over backhaul links, such as an Xn interface. A user equipment (UE) in the joint paging area may be provided the joint paging parameters and monitor for paging messages based on the joint paging configuration. In some cases, the UE may be provided the joint paging parameters in a resource release message. Additionally, or alternatively, a base station of the joint paging area may broadcast the joint paging parameters.

Abstract: A wireless network may provide system information by either a fixed periodic broadcast or broad-beam transmission or in response to a request by a user equipment (UE). The wireless network may broadcast (or broad-beam transmit) a signal that indicates to the UEs within a cell or zone coverage area that system information is to be transmitted on a fixed periodic schedule or in response to a request sent by one or more UEs.

Abstract: Methods, systems, and devices for wireless communication are described. A serving base station may determine a handover loss metric associated with a UE that is a candidate for handover. The handover loss metric may be based on connection parameters associated with the serving base station and a target base station, respectively. The serving base station may identify, based on the handover loss metric, a type of handover procedure to perform. The serving base station may perform the handover procedure of the UE to the target base station according to the identified handover type.
