Problems solved by technology

This is due to the fact that network access may be delayed due to interference occurring in the RACH, which causes traffic delays
[0007] In this way, a large number of RACH resources under limited resource conditions will lead to a reduction in the resources required to transmit other signals
Especially in the case of a wireless communication system using a small frequency band or a system with a large cell radius, the radio resources required to transmit other control signals may be further significantly reduced due to RACH resources

Embodiment Construction

[0028] The techniques described below can be used in various wireless communication systems, such as code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency Division Multiple Access (SC-FDMA), etc. CDMA can be implemented using wireless technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA-2000. TDMA can be implemented using, for example, Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE). The OFDMA may be implemented using, for example, the Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Evolved UTRA (E-UTRA), etc. UTRA is part of the Universal Mobile Telecommunications System (UMTS). The Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a part of Evolved UMTS (E...

Abstract

A method of transmitting a control signal includes transmitting a random access preamble on a random access channel (RACH) resource in a subframe, wherein the RACH resource includes a preamble period which is a time for transmitting the random access preamble and a cyclic prefix (CP) period which is a time for transmitting a CP, and transmitting a sounding signal on a single carrier-frequency division multiple access (SC-FDMA) symbol subsequent to the RACH resource in the subframe.

Description

Technical field [0001] The present invention relates to wireless communication, and more specifically, to a method of transmitting control signals in a wireless communication system. Background technique [0002] Wireless communication systems are widely deployed throughout the world to provide various types of communication services such as voice or data. Generally, a wireless communication system is a multiple access system (multiple access system) capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth, transmission power, etc.). Examples of multiple access systems include code division multiple access (CDMA) systems, frequency division multiple access (FDMA) systems, time division multiple access (TDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access ( SC-FDMA) system and so on. [0003] Orthogonal frequency division multiplexing (OFDM) syste...
