摘要:
This document is related to a wireless communication system, and more particularly to a method and an apparatus for transmitting encoded signals with frequency hopping environment. A method of transmitting signals by a user equipment (UE) comprises: encoding an input signal having a length of (A) bits by using (A) basis sequences having a length of 20 bits to output an encoded signal having a length of 20 bits, wherein (A) is a natural number less than 14; mapping the encoded signal having the length of 20 bits to two different resource regions, wherein the first 10 bits of the encoded signal are mapped to a first resource region, and the second 10 bits of the encoded signal are mapped to a second resource region; and transmitting the resource-mapped signals to a Node B, wherein the encoded signal or the (A) basis sequences are cyclic shifted with a value of (x) before mapping the encoded signal to the two different resource regions, wherein (x) is a natural number less than 20.

Provided are a method and apparatus for adjusting sounding reference signal transmission power. A terminal a plurality of transmit powers used for transmitting a plurality of sounding reference signals (SRSs) in a sounding reference symbol. If a total transmission power for the plurality of SRSs exceeds a maximum transmission power, the terminal scales each transmission power by the same scale factor.

Provided is a method and an apparatus for performing a random access process in a wireless communication system. A wireless device transmits a random access preamble, based on a random access resource, to a base station, then receives a random access response to the random access preamble. The random-access resource can be set to the wireless device or to the group to which the wireless device belongs.

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for performing processes in which a terminal determines control channel allocation, as well as to an apparatus for the method. The method comprises the following steps: monitoring, on a first carrier, a first search space, containing a control channel candidate set, for control channels having no carrier indication information; and monitoring, on a second carrier, a second search space, containing a control channel candidate set, for control channels having carrier indication information. If the terminal is set to monitor a plurality of control channel candidates which have the same radio network temporary identifier (RNTI), the same information size, and the same first control channel element (CCE) in the first search space and in the second search space, the control channels are received only in the first search space on the first carrier.

Provided are a method and an apparatus for transmitting ACK/NACK in a time division duplex (TDD)-based wireless communication system. A terminal receives zero or more downlink transmission blocks in M downlink subframes from a first serving cell, and determines an ACK/NACK state {HARQ-ACK(1), HARQ-ACK(2), HARQ-ACK(3), HARQ-ACK(4)} for the first serving cell. The terminal determines an ACK/NACK response based on said ACK/NACK state, and transmits the ACK/NACK response in an uplink subframe.

Disclosed are a method and a device for transmitting an ACK/NACK in a time division duplex (TDD)-based wireless communication system. A terminal receives an uplink grant that includes uplink resource allocation and piggyback information, and determines an ACK/NACK response for at least one downlink transmission block according to said piggyback information. The terminal multiplexes the ACK/NACK response with an uplink transport block and transmits the multiplexed ACK/NACK response.

Provided are a method and apparatus for transmitting a sounding reference signal. A terminal receives, from a base station, a configuration for periodic channel quality indicator (CQI) transmission and a configuration for sound reference signal (SRS) transmission. When a positive SRS request is detected, the terminal determines an SRS subframe winch satisfies the configuration for SRS transmission. When the periodically transmitted CQI is triggered in the SRS subframe, the terminal transmits the SRS in the SRS subframe to the base station.

Provided are a method and an apparatus for transmitting a reception confirmation in a wireless system. A terminal determines at least one downlink sub-frame for ACK/NACK feedback from each of a plurality of serving cells and determines the number of ACK/NACK bits for the plurality of serving cells. The terminal generates bundled ACK/NACK bits by arraying the ACK/NACK bits in the ascending order of the cell index of the plurality of serving cells, and transmits the bundled ACK/NACK bits.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting uplink control information where a plurality of cells are configured, and comprises: a step for receiving one or more PDCCH; a step for generating reception response information corresponding to the one or more PDCCH; and a step for transmitting through PUCCH the reception response information in a subframe, wherein the reception response information is transmitted using a PUCCH resource provided in advance by an upper layer signaling when only one PCell PDCCH is detected and the predetermined conditions are met, and is transmitted using a PUCCH resource linked to an index of a resource that makes up the PCell PDCCH when only one PCell PDCCH is detected and the predetermined conditions are not met.
