Token-based receiver diversity
First Claim
Patent Images
1. A network switch, comprising:
- a plurality of ports, each of the plurality of ports configurable to communicate with one of a corresponding plurality of repeaters, wherein multiple repeaters receive packets from one of a plurality of mobile stations assigned to the network; and
processing logic configured (i) to pre-assign a token to one of the plurality of repeaters, wherein the token uniquely associates one of the repeaters with one of the mobile stations, (ii) to receive a packet from the one mobile station at each of the plurality of ports corresponding to the multiple repeaters that received the packets, (iii) to determine whether the packet was received cleanly at the port corresponding to the repeater associated with the one mobile station as indicated by the pre-assigned token, and (iv) if the packet was not received cleanly at the port corresponding to the repeater associated with the one mobile station, then to re-assign the token to a selected one of the plurality of repeaters that did receive the packet cleanly.

Abstract
A token-based receiver diversity processing is described. In one embodiment, a receiver diversity comprises repeaters receiving wirelessly transmitted packets from a mobile station, and one of the repeaters forwarding packets of the wirelessly transmitted packets to a switch if the one repeater is currently assigned to forward packets from the mobile station based on an indicator assigned prior to the wirelessly transmitted packets being sent.

9. A method for coordinating communication in a network including a plurality of repeaters coupled to a network switch and a plurality of mobile stations broadcasting to the repeaters, the method comprising:
-
pre-assigning a token to one of the plurality of repeaters, wherein the token uniquely associates one of the repeaters with one of the mobile stations; receiving at the network switch a packet from one of the mobile stations via multiple repeaters; determining at the network switch whether the packet was received cleanly by the repeater associated with the one mobile station as indicated by the pre-assigned token; and if the switch determines that the packet was not received cleanly at the repeater associated with the one mobile station, then reassigning the pre-assigned token to a selected one of the plurality of repeaters that did receive the packet cleanly. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A computer useable medium storing computer program logic for enabling a processor in a network switch to coordinate communication in a network including a plurality of repeaters coupled to the network switch and a plurality of mobile stations broadcasting to the repeaters, the computer program logic comprising:
-
first means for enabling the processor to pre-assign a token to one of the plurality of repeaters, wherein the token uniquely associates one of the repeaters with one of the mobile stations; second means for enabling the processor to receive at the network switch a packet from one of the mobile stations via multiple repeaters; third means for enabling the processor to compare received packets to determine whether the packet was received cleanly by the repeater associated with the one mobile station as indicated by the pre-assigned token; and if the packet was not received cleanly at the repeater associated with the one mobile station, fourth means for enabling the processor to reassign the pre-assigned token to a selected one of the plurality of repeaters that did receive the packet cleanly. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
