Embodiment Construction

[0051] Embodiments of the present invention provide a method for transmitting an uplink control signal, a network side device, and a terminal device, so as to solve the technical problem of low resource utilization in the prior art.

[0052] In order to understand the technical solutions of the embodiments of the present invention more clearly, the embodiments of the present invention will be described by taking the transmission mode of the transmission control signaling of PUCCH Format2 / 2a / 2b in the LTE system as an example.

[0053] The LTE system uses Orthogonal Frequency Division Multiplexing (English: Orthogonal Frequency Division Multiplexing, OFDM for short) technology to subdivide "frequency" and "time" resources into: "subcarriers" and "SC-FDMA symbols". Taking the 20MHz of LTE as an example, the available bandwidth of 18MHz on the frequency is divided into 100 PRBs, expressed as Each PRB contains 12 consecutive subcarriers, expressed as The frequency interval betw...

Abstract

Disclosed are an uplink control signal transmission method, a network-side device and a terminal device. The method comprises: a terminal device encodes and modulates an uplink control signal to obtain uplink modulation data; the terminal device uses two orthogonal sequences to perform spread spectrum processing on the uplink modulation data to obtain spread spectrum data, the two orthogonal sequences being orthogonal sequences obtained by cyclic shifting based on the same base sequence; the terminal device maps the spread spectrum data onto corresponding sub-carriers on PRBs respectively to afirst time slot and a second time slot of uplink transmission resources and SC-FDMA symbols for data transmission; the terminal device places pilot sequences on corresponding SC-FDMA symbols for pilot transmission on the PRBs respectively to the first time slot and the second time slot; and the terminal device sends uplink data which include the SC-FDMA symbols for data transmission and the SC-FDMA symbols for pilot transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for transmitting an uplink control signal, a network side device and a terminal device. Background technique [0002] In the Long Term Evolution (English: Long Term Evolution, referred to as: LTE) system, uplink physical channels include: Physical Uplink Shared Channel (English: Physical Uplink Shared Channel, referred to as: PUSCH) and Physical Uplink Control Channel (English: Physical Uplink Control Channel , referred to as: PUCCH). [0003] The PUCCH is used to carry control signaling, and different control signaling can be transmitted using different PUCCH transmission formats. For example, the user equipment may feed back a channel quality indicator (English: Channel Quality Indicator, CQI for short) through a PUCCH format (Format) 2. If the base station requires the user equipment to feed back CQI and positive acknowledgment information (English: A...
