Uplink power control method and user equipment supporting both common and separate tpc commands

Abstract

A transmit power control (TPC) method and a user equipment (UE) of a telecommunications network utilizing the TPC method. The UE receives TPC commands intended for traffic and control channels. The TPC commands are separately identified by logical or physical resources associated with the channels. When the traffic and control channel TPCs occupy the same resources, the UE applies common power control commands to the traffic and control channels. When the traffic and control channel TPCs occupy different resources, the UE applies separate power control commands to the traffic and control channels.

1 . A transmission power control method for use in a base station of a telecommunications system, the system including a user equipment and multiple channels including traffic and control channels, each occupying allocated physical or logical resources between the base station and the user equipment, the method comprising:
 transmitting a message to the user equipment indicating a first identifier identifying transmit power control (TPC) commands for a traffic channel, and indicating a second identifier identifying TPC commands for a control channel;   transmitting for the traffic channel and the control channel, common TPC commands which occupy the same resources, when the first and second identifiers are the same; and   transmitting for the traffic channel and the control channel, separate TPC commands which occupy different resources, when he first and second identifiers are different.   
     
     
         2 . The method according to  claim 1 , further comprising transmitting the TPC commands on a physical downlink control channel (PDCCH) sent from the base station to the user equipment. 
     
     
         3 . The method according to  claim 2 , wherein the traffic channel is a physical uplink shared channel (PUSCH), and wherein the control channel is a physical uplink control channel (PUCCH). 
     
     
         4 . A base station of a telecommunications system, said system including a user equipment and multiple channels including traffic and control channels, each occupying allocated physical or logical resources between the base station and the user equipment, wherein the base station comprises:
 a transceiver for transmitting messages and commands to the user equipment; and   a processing circuit configured to cause the base station to:
 transmit a message to the user equipment indicating a first identifier identifying transmit power control (TPC) commands for a traffic channel, and indicating a second identifier identifying TPC commands for a control channel; 
 transmit for the traffic channel and the control channel, common TPC commands which occupy the same resources, when the first and second identifiers are the same; and 
 transmit for the traffic channel and the control channel, separate TPC commands which occupy different resources, when he first and second identifiers are different. 
   
     
     
         5 . The base station according to  claim 4 , wherein the base station is configured to transmit the TPC commands on a physical downlink control channel (PDCCH) sent from the base station to the user equipment. 
     
     
         6 . The base station according to  claim 5 , wherein the traffic channel is a physical uplink shared channel (PUSCH), and wherein the control channel is a physical uplink control channel (PUCCH).
