Technical Field
The present invention relates to the field of communications technologies, and in particular, to a downlink control information transmission method.
Background
Under the condition of multiple sub-bands, if uplink and downlink services need to be scheduled simultaneously, the LTE230 system needs to send two downlink control information DCIs simultaneously within one PDCCH period of a physical downlink control channel.
In the prior art, the two pieces of DCI carry uplink scheduling control information and downlink scheduling control information, which are both 39 bits, a terminal first detects the DCI carrying the uplink scheduling control information to obtain the length of the DCI carrying the uplink scheduling control information, and then obtains the position of the DCI carrying the downlink scheduling control information through calculation, thereby taking out corresponding data to detect the DCI carrying the downlink scheduling control information. The PDCCH can carry two DCI transmissions per period, the DCI occupying the initial frequency point is a first search space, and the other DCI is a second search space. Different aggregation levels of the PDCCH are detected through blind detection, and 1, 2, … and 1/2PDCCH span sub-bands can be occupied.
