Abstract

The embodiment of the invention provides a method for transmitting, receiving and processing information, a base station and user equipment. In the embodiment of the invention, UE (user equipment) can respectively extend four groups of modulating symbols to make at least one of two transmitted data sequence elements corresponding to the same subcarrier in two transmitted data sequences mapped on each subcarrier of a PRB (physical resource block) with a PUCCH (physical uplink control channel) corresponding to the same time slot of two antenna ports be 0, so that the UE can only use the same extending sequence to extend the two transmitted data sequences; in addition, first pilot frequency sequences placed on SC-FDMA (single carrier-frequency division multiple access) symbols for pilot frequency transmission in each time slot on the two antenna ports are orthogonal sequences after expansion of the same pilot frequency sequence, so that the two antenna ports can use the same pilot frequency sequence. Therefore, the uplink resource in the same PRB can support that the number of the UE which can send a control signaling in a PUCCH format 3 is doubled compared with the prior art, so that the resource utilization rate is improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a method for sending and receiving information, a base station, and user equipment. Background technique [0002] In a Long Term Evolution (hereinafter referred to as: LTE) system, uplink physical channels include: an uplink physical shared channel (Physical Uplink Shared Channel, hereinafter referred to as: PUSCH) and an uplink physical control channel (Physical Uplink Control Channel, hereinafter referred to as: PUCCH) and so on. [0003] The PUCCH is used to carry control signaling, and different control signaling can be transmitted in different PUCCH formats. For example, the uplink ACK / NACK message is transmitted using PUCCH format 3 (hereinafter referred to as format 3). format 3 consists of two time slots (hereinafter referred to as: slot), each slot occupies 1 physical resource block (Physical Resource Block, hereinafter referred to as: PRB), a PR...
