摘要： Techniques for reservation coordination and related operations in shared spectrum are disclosed. Communication over a communication medium may be performed in accordance with a first Radio Access Technology (RAT) and in accordance with a communication pattern of active periods and inactive periods of communication. A channel reservation message may be transmitted in accordance with a second RAT to reserve the communication medium for one of the active periods. The channel reservation message may be transmitted randomly at a plurality of successive burst slots. In addition or as an alternative, one or more medium access parameters associated with the channel reservation message may be set to a value below a threshold associated with aggressive contention.

摘要： An interference management scheme may detect a level of uncoordinated interference and compare a detected uncoordinated interference level against an intra-RAT (radio access technology) interference. Intra-RAT interference management algorithms or intra-RAT interference solutions are not triggered/applied if the uncoordinated interference is dominant. Alternatively, intra-RAT interference management algorithms may be triggered if co-channel intra-RAT interference is dominant.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for sounding reference signal (SRS) coordination, power control, and synchronization for distributed coordinated multipoint (CoMP) using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications by a network entity includes determining a first amount of transmission (Tx) power for transmission of signals originating from a first cluster center that is connected to the network entity, determining a second amount of Tx power for transmission of signals originating from at least a second cluster center that is connected to the network entity, and transmitting signals for one or more user equipment (UEs) served by the first cluster center and one or more UEs served by the second cluster center based on the first amount of Tx power and the second amount of Tx power.

摘要： In an embodiment, an apparatus (e.g., eNB) pages UEs on a shared communication. The apparatus obtains paging message(s) for transmission to UEs with different coverage levels. The apparatus transmits an extended common ePDCCH, followed by a paging ePDCCH, followed by repetitive transmissions of the paging message(s) over a plurality of PDSCH subframes. In a further embodiment, the apparatus obtains first and second sets of paging messages for transmission to different paging groups. The apparatus establishes non-overlapping POWs for the first and second paging groups to avoid a paging ePDCCH collision.

摘要： Techniques for intra- and inter-operator coordination on a shared communication medium are disclosed. A central coordination server may send an operating mode information message to coordinate operation of different points on the communication medium. An access point may receive such an operating mode information message and adjust one or more communication parameters. An access point may determine a level of timing synchronization with neighboring access points and send a synchronization advertisement message to an access terminal. An access terminal may receive a synchronization advertisement message and perform one or more measurements of the neighboring access points.
