Queuing far/far service requests in wireless network

Abstract

A technique for coordinating the operation of subscriber units such as in a wireless communications system so that high-probability-of-interference communications do not take place at the same time in adjacent cell sites. A base station becomes aware of expected periods or time slots of high relatively expected interference from remote units operating in a neighboring cell site, and then schedules only low interference level transmissions for its own remote units during such periods. Expected interference information ca be exchanged by base stations directly, through a centralized base station controller-initiated schedule, or by relaying resource load status messages via remote units located near all boundaries.

1 . A method for allocating resources in a wireless communication system comprising a plurality of cells, wherein each cell comprises a base station for communicating with a plurality of wireless transmit/receive units (WTRUs) within each of said cell, the method comprising: 
 a first base station within one of said cells receiving a request for access to available resources from at least one WTRU communicating with said first base station within said adjacent cell;    determining an interference level created by said requesting WTRU on communications within said cell; and    coordinating transmission of communications between said requesting WRTU and other WRTUs connected to a second base station in a cell adjacent to said first base station in response to said interference level.    
   
   
       2 . A method of  claim 1 , wherein said coordinating step comprises said first base station scheduling transmission of high interference communications associated with said requesting WRTU during times of transmission of low interference communications within said adjacent cell.  
   
   
       3 . A method of  claim 2 , wherein each of said first and second base stations is in communication with a plurality of WRTUs.  
   
   
       4 . The method of  claim 3 , wherein each of said first and second base stations determine an interference level for each WRTU communicating with said first base station.  
   
   
       5 . The method of  claim 2 , wherein said first base station receives a report of an expected time of low interference transmissions from said second base station within said adjacent cell.  
   
   
       6 . A method as in  claim 2 , wherein the coordinated communications are reverse link signals traveling from the WRTU to the base stations.  
   
   
       7 . A method as in  claim 2 , wherein the coordinated communications are forward link signals traveling from the base stations to the WRTUs.
