Abstract
In a mobile communication system comprising a base station (100) and a plurality of mobile stations (200) and operating closed loop transmitter power control, power control commands for transmission on an uplink are derived from measurements made on received downlink signals comprising nonpredetermined data values. Optionally the non-predetermined data values may comprise power control commands for uplink transmit power control.

wherein the power control circuit is configured to decode, within a slot of the plurality of slots, a single uplink power control command.
51. The mobile station of claim 50, wherein the radio receiver is configured to receive a common downlink pilot signal from the base station; and the signal analyzing circuit is further configured to perform downlink channel estimation based on the received common pilot signal.
52. The mobile station of claim 50, wherein a transmitted phase of the downlink fractional dedicated channel is referenced to a common pilot signal.
53. The mobile station of claim 52, wherein different antennas or antenna weights are used for the common pilot signal and the downlink fractional dedicated channel.
54. The mobile station of claim 50, wherein the signal analyzing circuit is further configured to measure an error rate of the uplink power control commands, and send the downlink power control commands when the measured error rate exceeds a predetermined threshold.
55. The mobile station of claim 50, wherein the fractional dedicated channel is configured to be shared among a plurality of mobile stations in the communication system.
56. The mobile station of claim 50, wherein the fractional dedicated channel is encoded with a same channel code for transmission of the plurality of uplink power control commands to the plurality of mobile stations in the communication system.
57. The mobile station of claim 50, wherein the mobile station is assigned a predetermined channel code and a predetermined fraction of a timeslot, and wherein the power control circuit is configured to decode the first downlink signal based on the predetermined channel code and the predetermined fraction of a timeslot.
58. The mobile station of claim 50, wherein each slot of the plurality of slots is configured to carry uplink power control commands for up to ten mobile stations in the communication system.
