Abstract: Methods, systems, and devices are described for wireless communications. The described techniques include separation of communication resources into resource sets based on data service sets for multiple base stations operating over a carrier of a shared spectrum. The base stations may use synchronized communication time resources. Each data service set may include one or more QoS types and/or communication services. Listen before talk (LBT) parameters for contention procedures performed in different resource sets may be different. A UE configured for communication over the carrier may employ a resource set based discontinuous reception (DRX) mode where a sleep mode is entered for resource sets not associated with active communications by the UE. Channel state information (CSI) reporting may be separated by resource sets for the carrier.

Abstract: Techniques for performing listen before talk (LBT) procedures in networks having multiple channels within a shared radio frequency spectrum band are provided. These techniques may include determining a contention window size for a first LBT procedure to access a first channel of a shared radio frequency spectrum band, which may then be applied as the contention window size for a second LBT procedure to access a second channel of the shared radio frequency spectrum band. The contention window size may be determined based at least in part on one or more of a service priority or a channel type for data to be transmitted using the first channel. Performing the first LBT procedure may include determining that a recipient base station has reserved the first channel and the second channel, and performing the second LBT procedure for the second channel.

Abstract: Methods and apparatus for wireless communication are described. A method may include receiving at a user equipment (UE) a number of allocated interlaces for an uplink transmission over a shared spectrum, each of which may include a plurality of non-contiguous resource blocks (RB) of the shared spectrum. In some cases, the number of allocated interlaces is unsupported by joint interlace precoding hardware of the UE and the allocated interlaces may be partitioned into subsets of interlaces which may be a size supported by the joint interlace precoding hardware. Reference signals may be generated for the RBs of the allocated interlaces according to a reference signal sequence based on an ordering of the RBs for the allocated interlaces within the shared spectrum.
