摘要:
A method and apparatus are provided for transmitting control information to first and second terminals by a Base Station (BS) in a wireless communication system transmitting control information according to a plurality of muting patterns. The method includes determining a resource for transmitting a Channel Status Information Reference Signal (CSI-RS) and a resource for applying muting; determining a resource for transmitting a control signal to a first terminal according to the plurality of muting patterns; and transmitting control information including the determined resource information to at least one of the first terminal and a second terminal. The resource for transmitting the control signal to the first terminal is applied as a resource to which muting is applied for the second terminal.

An improved power control method and apparatus of a mobile terminal is provided for facilitating random access procedure in a mobile communication system based on a distributed antenna system. A method includes receiving, by the terminal, system information from a base station, the system information including transmit power information for transmitting a random access preamble; calculating a transmit power using the transmit power information; and transmitting the random access preamble using with the calculated transmit power.
摘要:
Methods and apparatus for receiving a first control channel and a second control channel in a wireless communication system are provided. Control information for receiving the second control channel from a base station is received through higher layer signaling. A second control channel resource is determined from an entire control channel resource based on the control information. A first control channel resource is determined from the entire control channel resource according to the second control channel resource.
摘要:
A method for allocating resources of a common control channel includes determining a carrier type, allocating, when the carrier is backward compatible, resources for a Physical Control Format Indicator CHannel (PCFICH), and allocating resources for a common control channel with a dedicated reference signal based on a Physical Resource Block allocated for the PCFICH. A UE can receive the common control channel without extra signaling by mapping the common control channel to the frequency resource based on the cell-specific parameter or channel.
摘要:
A new structure of user-specific reference signals design is provided. Higher spectrum efficiency is achieved, and two users may share the same resource for control signal transmission in a distributed antenna system via different distributed antennas. In addition, search space overlapping is enabled and thus control resource reuse is made possible.

A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.
摘要:
Methods and apparatus are provided for scheduling in a communication system. A Coordinated Multi-point Transmission/Reception (CoMP) set of cells is determined for a terminal that supports a CoMP function. An indicator for use in scheduling one or more cells in the CoMP set and cell information corresponding to the indicator are transmitted to the terminal. Scheduling information with the indicator is transmitted to the terminal.
