Description

A kind of channel transmission method and device

Technical field

The present invention relates to communication technical field, more particularly to a kind of channel transmission method and device.

Background technology

Existing LTE FDD (FDD) system uses frame structure (frame structure type 1, abbreviation FS1), Its structure is as shown in Figure 1.In FDD system, uplink and downlink transmission uses different carrier frequencies, on Row and downlink transfer use identical frame structure.On each carrier, the radio frames bag of a 10ms length Containing 10 1ms subframes, it is divided into the time slot of 0.5ms length in each subframe again, uplink and downlink data are sent TTI when a length of 1ms.

Existing LTE TDD (time division duplex) system uses frame structure (frame structure type 2, abbreviation FS2), its structure is as shown in Figure 2.In a tdd system, uplink and downlink transmission is used in identical frequency Different subframes or different time-gap.Each 10ms radio frames are made up of two 5ms fields in FS2, each field In the subframe comprising 5 1ms length.Subframe in FS2 is divided into three classes：Descending sub frame, sub-frame of uplink and Special subframe, each special subframe by downlink transfer time slot (DwPTS, Downlink Pilot Time Slot), Protection interval (GP, Guard Period) and upstream transmission time slot (UpPTS, Uplink Pilot Time Slot) Three parts are formed.Wherein, DwPTS can transmit descending pilot frequency, downlink service data and descending control signaling； GP does not transmit any signal；UpPTS only transmits Stochastic accessing and detection reference signal (SRS, Sounding Reference Symbol), it is impossible to transmit uplink service or ascending control information.At least 1 is included in each field Individual descending sub frame and at least one sub-frame of uplink, and at most 1 special subframe.On 7 kinds performed in FS2 Descending sub frame configuration mode is as shown in table 1.
