Embodiment 1

[0068] This embodiment provides a method for sending uplink information, and the method includes the following steps S602 to S606.

[0069] Step S602: Map the uplink information to N PRBs in the frequency domain and X OFDM symbols in the time domain.

[0070] Step S604: Spread the information of X OFDM symbols in the time domain to M subframes by using the spread sequence.

[0071] Step S606: Send the uplink information on the M subframes, where M is a positive integer, X is a positive integer, and N is a positive integer.

[0072] Preferably, X is 1 OFDM symbol; or, X is the number of OFDM symbols occupied by information in 1 time slot; or, X is the number of OFDM symbols occupied by information in 1 subframe; or, X is P subframes The number of OFDM symbols occupied by the internal information, where P is a positive integer greater than 1 and less than or equal to M;

[0073] Preferably, the uplink information and the corresponding pilot are time-division multiplexed.

Embodiment 3

[0098] This embodiment provides a method for sending uplink control information. In this embodiment, it is assumed that the base station configures the physical resource block position {N 0 , N 1 ,...} (wherein through N i The frequency domain position where the uplink information is located and the number of frequency domain resource blocks N), the index of the spreading sequence {W 0 , W 1 ,...} (wherein through W i The spread sequence applied to the uplink information and the spread sequence applied to the pilot) and the uplink subframe {T 0 ,T 1 ,...}, assuming that UE according to the predefined uplink information C size The size is independently selected in the uplink subframe T 0 above, use resource block position N 1 (The frequency domain position where the uplink information is located is on the PRB whose PRB index is 1, then N=1), the index W of the extended sequence 1 (applied to the uplink information extension sequence {W 0 D , W 1 D ,...,W 11 D} and...

Abstract

The invention discloses a method and a device for uplink information transmitting. The method comprises the steps that uplink information is mapped to a pre-set time frequency resource, wherein the pre-set time frequency resource comprises N frequency domain PRB and X time domain orthogonal frequency division multiplexing OFDM symbol; by using a first extension sequence, the time domain resource occupied by the mapped uplink information is extended to M sub frame from X OFDM symbol, wherein N, X and M are positive integers; and the uplink information after extension processing is transmitted. According to the invention, the transmitting uplink multiplexing capacity and the uplink coverage are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending uplink information. Background technique [0002] The Long Term Evolution (LTE for short) system is an important plan of the third generation partnership organization. figure 1 shows a schematic structural diagram of a basic frame structure in an LTE system, such as figure 1 As shown, the frame structure is divided into four levels: radio frame, half frame, subframe, time slot and symbol. Among them, the length of a radio frame is 10ms, and a radio frame is composed of two half frames. The length of each half frame is 5ms, a half frame is composed of 5 subframes, and the length of each subframe is 1ms, and a subframe is composed of two time slots, and the length of each time slot is 0.5ms. When the LTE system uses a conventional cyclic prefix, a slot contains 7 uplink / downlink symbols with a length of 66.7us, among which, the cyclic prefix leng...
