Method and device for transmitting sounding reference signal and extended uplink control information in wireless communication system

摘要

The present invention relates to a wireless communication system, and more particularly, discloses a method and a device for transmitting a sounding reference signal and extended uplink control information in a wireless communication system. A method for a terminal transmitting the uplink control information through a physical uplink control channel in the wireless communication system, according to one embodiment of the present invention, comprises the following steps: creating a block by multiplying a modulation symbol, which shows the uplink control information, to a circular shift sequence, and creating a NSF blocks for each of the two slots of an uplink subframe; block-wise spreading the NSF blocks using an orthogonal code; and mapping a NRS reference signals and the block-wise spread NSF blocks to each of the two lots of the uplink subframe, and transmitting same to a base station, wherein the NSF blocks transmitted from the second slot of the uplink subframe can have an equal value when the transmission of the sounding reference signal is set and when the transmission of the sounding reference signal is not set in the uplink subframe.

主权项

1. A method of transmitting uplink (UL) control information via a physical uplink control channel (PUCCH) by a user equipment in a wireless communication system, the method comprising:
generating one or more blocks for each of 2 slots of a UL subframe by multiplying a modulated symbol for the UL control information and a cyclic-shifted sequence; block-wise spreading the blocks using an orthogonal code; and mapping one or more reference signals (RSs) and the spread blocks to the 2 slots of the UL subframe, respectively, and transmitting the RSs and the spread blocks to a base station, wherein a number of the blocks transmitted in a second slot among the 2 slots of the UL subframe has a same value for a case of configuring a transmission of sounding reference signal (SRS) in the UL subframe and a case of not configuring the transmission of the SRS.
