Embodiment Construction

[0022] The techniques, apparatus and systems described herein can be used in various wireless access technologies 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) and so on. CDMA may be implemented with a radio technology such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA can be implemented with radio technologies such as Global System for Mobile communications (GSM) / General Packet Radio Service (GPRS) / Enhanced Data Rates for GSM Evolution (EDGE). OFDMA may be implemented with radio technologies such as Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, Evolved UTRA (E-UTRA), and others. UTRA is part of the Universal Mobile Telecommunications System (UMTS). 3rd Generation Partnership Project (3GPP) Long Term Evo...

Abstract

A method and apparatus for adapting a repetition level for uplink (UL) transmission in a wireless communication is provided. A user equipment (UE) configures different number of repetitions per physical uplink control channel (PUCCH) format, and transmits a PUCCH format by using a corresponding number of repetitions among the different number of repetitions.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a method and apparatus for adapting repetition levels for uplink (UL) transmissions in a wireless communication system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is a technology for enabling high-speed packet communication. Many proposals have been proposed for LTE goals including aiming at reducing user and provider costs, improving service quality, and expanding and enhancing coverage and system capacity. 3GPP LTE requires reduction of cost per bit, increase of service availability, flexible use of frequency bands, simple structure, open interface, and appropriate power consumption of terminals as high-level requirements. [0003] In future versions of LTE-A, it has been considered to deploy low-cost / low-end (or, low-complexity) user equipment (UE) focused on data communication, such as meter reading, water l...
