Abstract

The present invention provides a method for sending uplink control information. The method includes: determining the uplink control information to be sent; encoding the uplink control information; interleaving the encoded uplink control information; interleaving the The subsequent uplink control information is sent on the physical uplink control channel PUCCH. The invention also provides a device for sending uplink control information.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for sending uplink control information in a new PUCCH format. Background technique [0002] The radio frame in the Long Term Evolution (LTE, Long Term Evolution) system and the Long Term Evolution Advanced (LTE-A, LTE-Advanced) system includes a Frequency Division Duplex (FDD, Frequency DivisionDuplex) mode and a Time Division Duplex (TDD) mode. , Time Division Duplex) mode frame structure. figure 1 It is a schematic diagram of the frame structure in the LTE / LTE-A FDD system in the prior art, such as figure 1 As shown, a 10 millisecond (ms) wireless frame is composed of 20 time slots (slots) with a length of 0.5ms and numbered 0 to 19, and time slots 2i and 2i+1 form a subframe (subframe)i with a length of 1ms ; figure 2 It is a schematic diagram of the frame structure in the LTE / LTE-A TDD system in the prior art. A 10ms radio frame is composed ...
