Abstract
The present invention is related to controlling delay in a wireless communication system. The present invention includes receiving a signal from a plurality of base stations, measuring at least one signal delay of each of the plurality of base stations, reporting the measured at least one signal delay of each base station to a controller controlling the plurality of base stations, and receiving an adjusted signal from each of the plurality of base stations as a result of reporting the measured at least one signal delay, wherein each adjusted signal is received in a synchronous manner.
Claims8
A method for controlling delay in a wireless communication system, the method comprising:
- transmitting at least one signal to a plurality of mobile stations, wherein the at least one signal is transmitted from two base stations, respectively;
- receiving a report from each of the plurality of mobile stations, wherein the report is related to at least one measured signal delay of the two base stations transmitting a signal to a respective mobile station;
- determining a time zone of each mobile station based on the received reports;
- determining a cyclic prefix length based on the received reports;
- determining a timing offset between the two base stations based on the received reports;
- and
- determining a set of mobile stations that can be served simultaneously by the two base stations according to the time zone of each mobile station, the determined cyclic prefix length and the timing offset between the two base stations.
A method for controlling delay in a wireless communication system, the method comprising:
- receiving at least one signal from two base stations, wherein the two base stations transmit the at least one signal to a plurality of mobile stations;
- measuring at least one signal delay of the two base stations;
- reporting the measured at least one signal delay of the two base stations;
- and
- receiving an adjusted signal from one of the two base stations in response to the reporting of the measured at least one signal delay,
- determining, based on the reported measured at least one signal delay, a time zone of each of the plurality of mobile stations, a cyclic prefix length, and a timing offset between the two base stations;
- and
- determining a set of mobile stations that can be served simultaneously by the two base stations according to the determined time zone of each of the plurality of mobile stations, the determined cyclic prefix length and the determined timing offset.
A network for controlling delay in a wireless communication system, the network comprising:
- two base stations respectively transmitting at least one signal to a plurality of mobile stations and receiving a report from each of the plurality of mobile stations, wherein the report is related to at least one measured signal delay of the two base stations transmitting a signal to a respective mobile station;
- and
- a controller determining a time zone of each mobile station based on the received reports, determining a cyclic prefix length based on the received reports, determining a timing offset between the two base stations based on the received reports, and determining a set of mobile stations that can be served simultaneously by the two base stations according to the time zone of each mobile station, the determined cyclic prefix length and the timing offset between the two base stations.
