Setting power control for a first message based on power used for successfully transmitted preamble

摘要

A method and an apparatus for transmit power control of a first message on physical uplink shared channel during a random access channel procedure on physical random access channel are disclosed. The apparatus comprises a means for performing transmit power control on transmitting a random access channel preamble sufficient for successful receipt; a means for receiving a random access response including a transmit power control command for physical uplink shared channel; and a means for setting transmit power control for a first message transmitted on physical uplink shared channel based at least in part upon the transmit power control command. The means of the apparatus comprise a transmitter for transmitting a physical random access channel and physical uplink shared channel; a receiver; a medium access control layer for performing transmit power control on transmitting the random access channel preamble; and a physical layer for setting transmit power control for the first message transmitted on physical uplink shared channel based upon the random access channel preamble that was successfully received. A method and an apparatus for transmit power control of a first message on physical uplink shared channel during a random access channel procedure on physical random access channel are disclosed. The apparatus comprises means for receiving a random access channel preamble; means for acknowledging successful receipt of the random access channel preamble; means for receiving a random access channel message containing an indication of transmit power control used for the random access channel preamble that was successfully received; and means for transmitting a random access response including a transmit power control command for a first message transmitted on physical uplink shared channel based at least in part upon a transmit power control for the random access channel preamble that was successfully received. The means of the apparatus comprise a receiver for receiving the random access channel preamble on the physical random access channel; a transmitter for acknowledging successful receipt of the random access channel preamble; the receiver further for receiving the random access channel message containing the indication of transmit power control for the random access channel preamble that was successfully received; and a computing platform for transmitting via the transmitter the random access response including the transmit power control command for the first message transmitted on physical uplink shared channel based at least in part upon the transmit power control for the random access channel preamble that was successfully received.
