摘要:
A method and apparatus for requesting uplink resources in a wireless communication system is provided. A user equipment determines whether a scheduling request for requesting uplink resources is triggered. If the scheduling request is triggered, the user equipment transmits a first set of frequency domain sequences and a second set of frequency domain sequences in a subframe.

The present invention provides a method and an apparatus for the transmission of control signal in a radio communication system. The method includes the steps of processing first control information on the basis of a first resource index to create a first control signal, processing second control information on the basis of a second resource index to create a second control signal, and transmitting the first control signal and the second control signal.

A method for uplink transmitting control information from a user equipment in a wireless communication system comprises selecting a specific point among a plurality of points distributed into a symbol space, corresponding to control information, the symbol space including a modulation dimension and a sequence dimension; mapping a signal corresponding to the specific point with a control channel including single carrier-frequency division multiple access (SC-FDMA) symbols; and transmitting the control channel. Preferably, the specific point belongs to the sequence dimension.

A method and device for transmitting uplink control signals in a wireless communication system, the method including: reserving a preassigned scheduling request (SR) physical uplink control channel (PUCCH) resource used for transmission of a SR; determining a frequency domain sequence and an orthogonal sequence based on the preassigned SR PUCCH resource; spreading an ACK/NACK for Hybrid Automatic Repeat Request (HARQ) with the frequency domain sequence and the orthogonal sequence to generate a mapped sequence; and transmitting the mapped sequence
摘要:
A method of transmitting uplink control signals in a wireless communication system includes preparing a ACK/NACK resource for transmitting the ACK/NACK signal for HARQ of downlink data on an uplink control channel, preparing a scheduling request resource for transmitting a scheduling request and the ACK/NACK signal on the uplink control channel in one subframe, and transmitting the ACK/NACK signal on the uplink control channel configured by the scheduling request resource for the positive transmission of the scheduling request and transmitting the ACK/NACK signal on the uplink control channel configured by the ACK/NACK resource for negative transmission of the scheduling request.
