Description
Technical field
The present invention relates to fields of communication technology, more particularly, to DCI transmission method in a kind of discrete spectrum communication system
And equipment.
Background technique
In broadband access system based on TD-LTE technology, system available bandwidth is divided into multiple sons continuously or discontinuously
Band uses orthogonal frequency division multiplexing (OFDM) technical transmission on each subband.According to function by sub-band division be synchronous subband, broadcast
Subband and service sub-band.Synchronous subband connects for sending downlink synchronous signal, broadcasting sub-band for downlink broadcast and uplink random
Enter, service sub-band is used for transmission business.In order to reduce terminal cost, system supports list band operating mode, and each physical channel must
It must be independently transmitted on each subband.Terminal selects work on all or part of subband according to the different of hardware capabilities, ability
Most weak terminal only works in list band.One typical application scenarios is electric system radio bandwidth access network, abbreviation TD-
LTE230 network, frequency spectrum it is discrete be distributed in 230MHz frequency range, each subband 25kHz, frequency resource distribution schematic diagram such as Fig. 1
It is shown.
Depth covering is supported in TD-LTE230 network requirement, to promote each physical channel transmission performance, is used and is repeated in time domain
Sending method, and periodicity sending is used to obtain time diversity gain.Therefore, the sequential relationship of data transmission is as follows: one
In the PDCCH period, PDCCH sends uplink authorization information scheduling PUSCH and/or downstream grants message scheduling PDSCH, PDCCH biography
The defeated time depends on the PDCCH of the PDCCH maximum number of repetitions that RRC information configures and uplink authorization and/or downstream grants configuration
Number of repetition；Next radio frames start to transmit PUSCH and/or PDSCH, PUSCH after PDCCH last time repeats the end of transmission
The transmission block that transmission time depends on uplink authorization configuration occupies radio frames number and number of repetition, PDSCH transmission time are depended on
Radio frames number and number of repetition are occupied in the transmission block of downstream grants configuration；The feedback information of uplink transmission block passes through interval one
NDI is indicated in the uplink authorization information in next PDCCH period in a PDCCH period, and the feedback information of downstream transmission blocks passes through
Next radio frames start the PUCCH transmitted carrying after PDSCH last time repeats the end of transmission, and PUCCH occupancy one is wireless
Whole sub-frame of uplink of frame, when the PDSCH transmission time being greater than 16 radio frames, PUCCH occupies 2 radio frames, otherwise occupies 1
A radio frames.
In existing LTE system, search space is distributed within the scope of system full bandwidth, and terminal, which must have, monitors full bandwidth
Ability does not support the terminal only to work in the continuous subband of list band or part.In some solutions, in business transmission process
DCI is fixed on first subband and sends, and can not improve PDCCH performance using broadband resource, it is difficult to support different covering demands
Terminal.
