Title: DYNAMIC ALLOCATION IN DENSE MMWAVE NETWORKS
Abstract:
Systems, methods, and/or instrumentalities are disclosed for dynamic allocation (e.g. of communication channel time with an access point (AP)) to a plurality of wireless transmit/receive units (STA(s)/WTRUs) in dense mmWave networks. Dynamic allocation may be implemented in multiple (e.g. four) sub-phases, (e.g. a polling period sub-phase with polls, a polling period sub-phase with service period requests (SPRs), a grant sub-phase and/or a data transfer sub-phase). Multi-dimensional dynamic allocation may address multiple STAs simultaneously (e.g. using one or more different dimensions such as space, frequency, and/or code). Directional channel access may provide a contention-based uplink in which STAs compete (e.g. during an uplink request period) to send data requests. Efficient dynamic allocation may optimize signaling and/or operation in sub-phases (e.g. using grouped polling, grouped SPR and/or grouped grant frames). Dynamic allocation with subphase overlap may allow different sub-phases of a dynamic allocation procedure to overlap.
