    Abstract: Methods, systems, and devices for wireless communications are described in which base stations and user equipment (UEs) may transmit using identified wireless resources in millimeter wave (mmW) radio frequency spectrum. A UE may receive an uplink grant from a base station that indicates uplink resources for transmission of uplink data from the UE to the base station in a shared mmW radio frequency spectrum band. An indication of a duration of a listen-before-talk (LBT) procedure may be provided in or with the uplink grant. The UE may perform, responsive to receiving the uplink grant, the LBT procedure to determine that the shared mmW radio frequency spectrum band is available for the uplink transmission. Based on the outcome of the LBT procedure, the UE may transmit the uplink data to the base station using the uplink resources indicated in the uplink grant.

    Abstract: A Global System for Mobile Communications (GSM) network supports multi-carrier operation on the downlink and/or uplink for a mobile station. The mobile station receives an assignment of multiple carriers for a first link in the GSM network, receives an assignment of at least one carrier for a second link in the GSM network, and exchanges data with the GSM network via the multiple carriers for the first link and the at least one carrier for the second link. The first link may be the downlink and the second link may be the uplink, or vice versa. The mobile station may receive data on multiple carriers at the same time for multi-carrier operation on the downlink. The mobile station may transmit data on multiple carriers at the same time for multi-carrier operation on the uplink.

    Abstract: Wireless communications systems and methods related to signaling medium reservation information medium sharing among multiple radio technologies (RATs) are provided. A first wireless communication device communicates, with a second wireless communication device, a reservation signal to reserve a transmission opportunity (TXOP) in a spectrum. The spectrum is shared by multiple RATs. The reservation signal includes a plurality of first waveform sequences indicating medium reservation information detectable by the multiple RATs. The first wireless communication device and the second wireless communication device are associated with a first RAT of the multiple RATs. The first wireless communication device communicates, with the second wireless communication device using the first RAT, a communication signal in the spectrum during the TXOP.

    Abstract: Various aspects are described relating to wireless communications of a second type of traffic data for small data transmissions. A first indication of control channel resources can be received from a network entity, wherein the control channel resources are defined by a radio access technology to include control data associated with a first type of traffic data. A control channel can be received from the network entity over the control channel resources, wherein the control channel includes a second type of traffic data, wherein the second type of traffic data includes a comparatively smaller data payload than the first type of traffic data. The second type of traffic data can be decoded from the control channel without decoding control data from the control channel.

    Abstract: Systems and methodologies are described that facilitate handing over mobile device communications in a wireless network from a source base station to a target base station without using a random access channel (RACH). In this regard, the source base station can request shared data bandwidth resources from the target base station on behalf of the mobile device and assign the resources to the mobile device. The mobile device can calculate a timing difference between the source and target base stations and can handover communications by transmitting over the shared data bandwidth using the timing difference to generally provide correct timing for the transmission. To this end, the target base station can have transmission time intervals where it allows transmitting with an extended cyclic prefix to ensure more reliable handover for the mobile device.
