APPARATUS AND METHODS FOR SCHEDULING RESOURCES IN MESH NETWORKS

摘要

Methods and apparatuses are described herein that facilitate mesh network communication by a millimeter wave base stations (mBs) or WTRUs as nodes of a directional mesh network with other nodes of the directional mesh network. The mB or WTRU may include a directional antenna configured to transmit and receive signals in specific directions during the mesh network communication to define a directional mesh network. The mBs or WTRUs may transmit transmission request messages to neighbor nodes, wherein the transmission request messages include transmission slot allocation bitmaps and channel quality indicator information (CQI). Then response messages from the neighbor nodes may be received, wherein the response messages include receive slot allocation bitmaps and resource allocation decisions. The mBs or WTRUs may then update their transmission slot allocation bitmaps based on the received response messages and transmit data packets in specific directions based on the updated transmission slot allocation bitmap.

1. A method for scheduling resources in a wireless mesh network, the method comprising:
transmitting, via a directional antenna, a first transmission request message to a first neighbor node of a plurality of neighbor nodes, wherein the first transmission request message includes a transmission slot allocation bitmap; receiving, via the directional antenna, a first response message from the first neighbor node of the plurality of neighbor nodes, wherein the first response message includes a first receive slot allocation bitmap and a first resource allocation decision; updating the transmission slot allocation bitmap based on the received first response message; transmitting, via the directional antenna, a second transmission request message to a second neighbor node of the plurality of neighbor nodes, wherein the second transmission request message includes the updated transmission slot allocation bitmap; receiving, via the directional antenna, a second response message from the second neighbor node of the plurality of neighbor nodes, wherein the second response message includes a second receive slot allocation bitmap and a second resource allocation decision; updating the transmission slot allocation bitmap based on the received second response message; and transmitting data packets in specific directions, via the directional antenna, wherein a transmission beam associated with the directional antenna is aligned based on the updated transmission slot allocation bitmap.
