Abstract
A method and an apparatus are provided for receiving information by a terminal in a wireless communication system. The method includes transmitting, to a base station, a request message including a preamble; receiving, from the base station, a response message including uplink resource information determined based on the preamble; determining at least one of downlink channel information and uplink transmission capability corresponding to a specific uplink transmission; and transmitting, if an information request message is received from the base station, the at least one of the downlink channel information and the uplink transmission capability to the base station.
Claims16
A method for receiving information by a terminal in a wireless communication system, the method comprising:
- transmitting, to a base station, a request message for a random access including a preamble;
- receiving, from the base station, a response message including uplink resource information in response to the request message;
- transmitting, to the base station, a first message based on the uplink resource information, the first message including information on an identity of the terminal;
- identifying downlink channel information based on the response message and uplink transmission capability information corresponding to the first message;
- and
- transmitting, to the base station, the downlink channel information and the uplink transmission capability information, if an information request message is received from the base station,
- wherein the uplink transmission capability information includes at least one of a number of transmission-available bits for available uplink power and an uplink power margin for the specific uplink transmission.
A method for transmitting information by a base station in a wireless communication system, the method comprising:
- receiving, from a terminal, a request message for a random access including a preamble;
- transmitting, to the terminal, a response message including uplink resource information in response to the request message;
- receiving, from the terminal, a first message based on the uplink resource information, the first message including information on an identity of the terminal;
- and
- receiving, from the base station, downlink channel information identified based on the response message and uplink transmission capability information corresponding to the first message, if an information request message is transmitted to the terminal,
- wherein the uplink transmission capability information includes at least one of a number of transmission-available bits for available uplink power and an uplink power margin for the specific uplink transmission.
An apparatus of a terminal for receiving information in a wireless communication system, the apparatus comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller coupled to the transceiver and configured to:
- transmit, to a base station, a request message for a random access including a preamble,
- receive, from the base station, a response message including uplink resource information in response to the request message,
- transmit, to the base station, a first message based on the uplink resource information, the first message including information on an identity of the terminal,
- identify downlink channel information based on the response message and uplink transmission capability information corresponding to the first message, and
- transmit, to the base station, the downlink channel information and the uplink transmission capability information, if an information request message is received from the base station,
- wherein the uplink transmission capability information includes at least one of a number of transmission-available bits for available uplink power and an uplink power margin for the specific uplink transmission.
An apparatus of a base station for transmitting information in a wireless communication system, the apparatus comprising:
- a transceiver configured to transmit and receive a signal;
- and
- a controller coupled to the transceiver and configured to:
- receive, from a terminal, a request message for a random access including a preamble, transmit, to the terminal, a response message including uplink resource information in response to the request message,
- receive, from the terminal, a first message based on the uplink resource information, the first message including information on an identity of the terminal, and
- receive, from the base station, downlink channel information identified based on the response message and uplink transmission capability information corresponding to the first message, if an information request message is transmitted to the terminal,
- wherein the uplink transmission capability information includes at least one of a number of transmission-available bits for available uplink power and an uplink power margin for the specific uplink transmission.
