In the embodiment of the present invention, PDCCH resource configuration information and PDCCH search space that the network equipment can be generated Configuration information is sent to UE, so that UE is generated at least according to PDCCH resource configuration information and PDCCH search space configuration information One is used for the search space of UE blind examination PDCCH.
Optionally, the network equipment passes through minimum system information, system information block, radio resource control signaling, media access PDCCH resource configuration information is sent to UE by control layer control signaling or common set PDCCH message.
S103, UE receive the PDCCH resource configuration information and PDCCH search space configuration information that the network equipment is sent.
In the embodiment of the present invention, UE can receive minimum system information, system information block, the wireless money of network equipment transmission Then source control signaling, media access control layer control signaling or common set PDCCH message are believed from minimum system information, system PDCCH resource is obtained in breath block, radio resource control signaling, media access control layer control signaling or common set PDCCH message Configuration information and PDCCH search space configuration information.
S104, UE generate at least one PDCCH according to PDCCH resource configuration information and PDCCH search space configuration information Search space.
Specifically, above-mentioned S104 can specifically be realized by S104a to S104b:
S104a, UE determine that the network equipment is the quantity of the CCE of UE configuration according to PDCCH resource configuration information, and to all CCE number.
In the embodiment of the present invention, UE can be provided according to the time-frequency for the PDCCH resource configuration information instruction that the network equipment is sent Source determines that the network equipment is the quantity of the CCE of UE configuration.Specifically, UE can according to the quantity of the PRB of network equipments configuration, The quantity of OFDM symbol determines the quantity of resource element groups (resource elements group, REG), then in basis The quantity of REG determines the quantity of CCE.
Illustratively, it is assumed that the quantity 12 of the PRB of network equipments configuration, the quantity of OFDM symbol are 2, then the quantity of REG For the product of the quantity of the quantity and OFDM symbol of PRB, i.e. the quantity of REG is 24, it is assumed that a CCE includes 6 REG, then leads to The quantity for crossing REG determines that the quantity of CCE is 4.
After above-mentioned UE determines the quantity of CCE, UE can number for all CCE of network equipments configuration, it is assumed that UE is true The quantity of fixed CCE is N, and UE can be by this N number of CCE marked as CCE0, CCE1 ..., CCE N-1, such as N=8, this 8 CCE number is CCEO, CCE1, CCE2, CCE3, CCE4, CCE5, CCE6 and CCE7.
S104b, UE generate at least one according to all numbered CCE, the first configuration information and the second configuration information PDCCH search space.
In the embodiment of the present invention, due to including the polymerization grade of CCE and the number of PDCCH Candidate Set in the first configuration information Amount, PDCCH search space type that UE can determine configuration according to the polymerization grade of CCE and each PDCCH Candidate Set are by more Few CCE is polymerized；UE can determine to include how many in each PDCCH search space according to the quantity of PDCCH Candidate Set PDCCH Candidate Set.
Illustratively, it is assumed that in the first configuration information, CCE polymerization grade is 2,4, and the PDCCH corresponding to polymerization grade 2 is waited The quantity of selected works is 5, and the quantity of the PDCCH Candidate Set corresponding to polymerization grade 4 is 4, then two kinds of PDCCH search can be generated in UE Space, the first PDCCH search space include 5 PDCCH Candidate Sets that polymerization grade is 2, second of PDCCH search space packet Include 4 PDCCH Candidate Sets that polymerization grade is 4.
Further, UE knows that at least one PDCCH search is empty according to PDCCH resource configuration information and the first configuration information Between basic condition after, UE can accurately generate at least one PDCCH search space according to the second configuration information.For example, According to the direction of search that the second configuration information indicates, the gap between start offset amount and PDCCH Candidate Set is searched for, is generated extremely A few PDCCH search space.
It should be noted that UE can generate a variety of different search spaces by the above method, when PDCCH resource configures Information is different with PDCCH search space configuration information, then different search spaces can be generated, specifically, can be according to reality Demand, the network equipment are the PDCCH resource configuration information and PDCCH search space configuration information of UE configuration response, so that UE generates the PDCCH search space that can achieve different technologies effect.Below with several examples, UE generation is introduced respectively PDCCH search space.
It should be noted that in following examples, by taking the quantity of CCE is 28 as an example.Remember the search space that polymerization grade is 8 For the first search space, the search space that polymerization grade is 4 is denoted as the second search space, and the search space that polymerization grade is 2 is remembered For third search space, the search space that polymerization grade is 1 is denoted as the 4th search space.
