Association and resource partitioning in a wireless network with relays

摘要

Techniques for performing association and resource partitioning in a wireless network with relays are described. In an aspect, resource partitioning may be performed to allocate available resources to nodes and access/backhaul links of relays. In one design, a node computes local metrics for a plurality of possible actions related to resource partitioning. The node receives local metrics for the possible actions from at least one neighbor node and determines overall metrics for the possible actions based on the computed and received local metrics. The node determines resources allocated to a set of nodes and resources allocated to the access and backhaul links of at least one relay based on the overall metrics for the possible actions. In another aspect, association involving relays may be performed by taking into account the performance of the relays. In yet another aspect, association and resource partitioning may be performed jointly.

1. A method for wireless communication, comprising:
obtaining, using at least one network entity, loading information corresponding to at least one neighbor node; obtaining, using the at least one network entity, metrics for a plurality of possible actions related to association involving at least one relay; determining, using the at least one network entity, at least one serving node for at least one station based on said loading information and the metrics for the plurality of possible actions; communicating, using the at least one serving node, with the at least one station; wherein the at least one serving node is one of a base station or the at least one relay; wherein the metrics for the at least one relay are based on at least one of:
resources allocated to access and backhaul links of the at least one relay,an access capacity of the at least one relay, ora backhaul capacity of the at least one relay; and wherein said network entity is one of said base station or said at least one relay, said at least one relay operating as a network node capable of communicating with said at least one station on an access link.
