Embodiment 1

[0107] Such as image 3 As shown, the embodiment of the present invention provides a method for sending uplink control information, including:

[0108] Step 31, when there is a collision between different types of uplink control information UCI corresponding to the first transmission time interval TTI length and / or there is a collision between UCI corresponding to the first TTI length and UCI corresponding to the second TTI length, then in On the sPUCCH resource corresponding to the preset second short physical uplink control channel sPUCCH format, use the second sPUCCH format to simultaneously transmit the collided UCI to the base station, or, according to the sPUCCH format used by the UCI corresponding to the first TTI length, determine The transmission method of UCI with collision;

[0109] It should be noted that the first TTI length is shorter than the second TTI length, for example, the second TTI length is 1 ms, the first TTI length is M symbols, and M is a positive in...

Embodiment 2

[0176] Such as Image 6 As shown, the embodiment of the present invention provides a terminal 60, including:

[0177]The transmission module 61 is used for when there is a collision between different types of uplink control information UCI corresponding to the first transmission time interval TTI length and / or there is a collision between UCI corresponding to the first TTI length and UCI corresponding to the second TTI length , then on the sPUCCH resource corresponding to the preset second short physical uplink control channel sPUCCH format, use the second sPUCCH format to simultaneously transmit the UCI with collision to the base station, or, according to the sPUCCH used by the UCI corresponding to the first TTI length Format, which determines the transmission method of UCI with collision.

[0178] Optionally, the transmission module 61 is also used for:

[0179] If the UCI corresponding to the first TTI length adopts the first sPUCCH format, on the preset sPUCCH resource c...

Abstract

The invention provides a method for transmitting and receiving uplink control information, a terminal, and a base station, and relates to the technical field of communication. The method for transmitting the uplink control information comprises the following steps: when different types of uplink control information UCI corresponding to the length of a first transmission time interval TTI occur collision and / or when the UCI corresponding to a first TTI length generates collision with the UCI corresponding to a second TTI length, transmitting the UCIs generating the collision to the base stationin a second sPUCCH format at the same time on an sPUCCH resources corresponding to a preset second short physical uplink control channel sPUCCH format, or, determining a transmission method of the UCIs generating the collision according to the sPUCCH format adopted by the UCI corresponding to the first TTI length. By adoption of the scheme, on the basis of shortening the transmission delay of theUCI corresponding to the short TTI, the UCIs generating the collision are transmitted to the base station as much as possible to ensure that the base station can obtain various UCI feedback information in time, thereby ensuring the reliability of the network communication.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending and receiving uplink control information, a terminal and a base station. Background technique [0002] The existing Long Term Evolution Frequency Division Duplex (LTE FDD) system uses a type 1 frame structure (frame structure), referred to as FS1. In the FDD system, different carrier frequencies are used for uplink and downlink transmission. Both downlink and downlink transmissions use the same frame structure. Such as figure 1 As shown, on each carrier, a 10ms length radio frame (radio frame) contains 10 1ms subframes (subframe), and each subframe is divided into two 0.5ms long time slots (slots), uplink and downlink The transmission time interval (Transmission Time Interval, TTI) duration of data sending is 1 ms. [0003] The existing LTE Time Division Duplex (TDD) system uses a type 2 frame structure, FS2 for short. In the TDD system, upl...
