Adaptive association and joint association and resource partitioning in a wireless communication network

摘要

Techniques for supporting communication in a wireless network are described. In an aspect, association and resource partitioning may be performed jointly to select serving base stations for user equipments (UEs) and to allocate available resources to base stations. In another aspect, adaptive association may be performed to select serving base stations for UEs. In one design, a base station computes local metrics for different possible actions related to association and resource partitioning (or only association). The base station receives local metrics for the possible actions from at least one neighbor base station and determines overall metrics for the possible actions based on the computed and received local metrics. The base station determines serving base stations for a set of UEs and resources allocated to the set of base stations (or just serving base stations for the set of UEs) based on the overall metrics for the possible actions.

主权项

1. A method for wireless communication, comprising:
making pilot measurements for base stations detectable by a user equipment (UE), wherein the pilot measurements are used to determine an active set for the UE, or to compute metrics for adaptive association, or to compute metrics for joint association and resource partitioning, or a combination thereof; transmitting the pilot measurements to a base station; receiving, at the UE, an assignment of at least one resource from the base station, the assignment being based on adaptive association or joint association and resource partitioning for a set of base stations including the base station,
wherein adaptive association determines serving base stations for a set of UEs including the UE based on the transmitted pilot measurements, andwherein joint association and resource partitioning determines serving base stations for the set of UEs and allocates available resources to the set of base stations based on the transmitted pilot measurements, wherein the base station is allocated a subset of the available resources, and wherein the at least one resource assigned to the UE is from the subset of the available resources allocated to the base station; and communicating with the base station on the at least one resource by the UE.
