摘要:
A method for receiving downlink data by a User Equipment (UE) in a wireless communication system is provided. The method includes checking a transmission parameter related to data transmitted from an interfering cell, determining presence/absence of an interference signal based on the transmission parameter, determining whether to apply Network Assisted Interference Cancellation and Suppression (NAICS) technology based on at least one of the transmission parameter or the presence/absence of the interference signal, and decoding the downlink data depending on whether to apply the NAICS technology.

An apparatus and method for radio link monitoring in a wireless communication system are provided, in which a transmission point communicating with a network where a Base Station (BS) and at least one Remote Radio Head (RRH) coexist within a cell receives Reference Signal Configuration Information (RSCI) from the network to which the transmission point belongs, receives RSs of at least one RS type indicated by the received RSCI from the BS and the at least one RRH that coexist within the cell, and performs radio link monitoring using the received RSs of the at least one RS type.

A method for transmitting control data on a downlink and/or uplink channel in a base station and/or mobile station in a mobile communication system. In one embodiment, the base station determines whether there is downlink channel data to transmit to a mobile station. If there is no data to be transmitted over the downlink channel for a predetermined time period, the base station drives a random gating position selector to determine a random gating slot position, gates on the control data at the determined slot position, and gates off the control data at other slot positions. The random position selector determines the gating slot position by calculating a value x by multiplying a system frame number (SFN) of a received signal by a specific integer; selecting n bits starting from a position which is at an x-chip distance from the start point of a scrambling code, which has a period equal to one frame, before a plurality of gating durations used in generating a downlink signal; and determining a gating slot position of a corresponding gating slot group by performing a modulo operation on the selected n bits, where the module operation is by the number of slots in a gating slot group.

A method for controlling a reply signal transmission in a mobile communication system. The method includes determining whether an error is detected in the received data through the radio channel, generating a reply signal according to the error detection, determining a repetition control signal with a value that differs according to a data transmission rate, repeatedly replicating the reply signal according to the repetition control signal, and transmitting the replicated reply signal through the radio channel.

Disclosed is a method and device for transmitting a sounding reference signal (SRS) in a cooperative communication system. The method comprises the steps of: receiving, from a macro base station, SRS resource information indicating transmission resources of an SRS to be transmitted by a user equipment (UE); transmitting the SRS and uplink data on the basis of a UE-specific SRS subframe configuration included in the SRS resource information when the SRS resource information includes information on the UE-specific SRS subframe configuration; and transmitting the SRS and the uplink data on the basis of a pre-stored cell-specific SRS subframe configuration when the SRS resource information does not include the information on the UE-specific SRS subframe configuration. When a destination of the SRS to be transmitted by the UE is selected as a base station related to the macro base station, the SRS resource information includes information on the UE-specific SRS subframe configuration of the base station selected as the destination of the SRS.

An apparatus and a method for generation of channel state information in a wireless communication system are provided. The method includes transmitting, by an evolved Node B (eNB), a first reference signal to a plurality of User Equipments (UEs), receiving channel state information generated based on the first reference signal from the plurality of UEs, selecting candidate UEs to which wireless resources are to be allocated and transmitting second reference signals to the selected candidate UEs, receiving channel state information generated based on the second reference signals from the candidate UEs, and selecting final UEs, to which wireless resources are to be allocated, from the candidate UEs based on the channel state information generated based on the second reference signals, and transmitting control information for data reception to the selected final UEs.

Disclosed is a method for controlling a reverse data rate by a mobile station in a mobile communication system supporting high-rate packet data transmission. The method includes receiving average loading information (FRAB) from a particular base station when the mobile station attempts an initial access to the base station; setting the received average loading information as average loading information for the base station; and upon receiving reverse activity information (RAB) from the base station, controlling a rate of reverse data using the received reverse activity information and the set average loading information.
摘要:
A communication method in a mobile communication system in which an access terminal transmits to an access network DRC information indicating a selected one of forward data rates requested by the access terminal is provided. The access network designates a DRC information length DRC Length indicating a number of slots where the DRC information is repeated and transmits the designated DRC information length to the access terminal. The access terminal gates transmission of DRC information to the access terminal at one time slot in every DRC information length received from the access network.
