Embodiment 1
[0134] In the first embodiment, taking the number of bits of the response information of 2 bits as an example, the solution for allocating control channel resources in the technical solution of the present invention is described in detail. High-level signaling pre-configured N 0 =0, or the base station and UE pre-appoint N 0 =0.
[0135] against Figure 6A , Figure 6B , Figure 6C with Figure 6D In the scenario shown, when the UE supports cross-carrier scheduling, that is, when the PDCCH on the DL PCC is cross-carrier scheduling, that is, when all data packets are scheduled from the PDCCH on the DL PCC, the UE can follow DL CC1 (the DL CC1 is DL PCC) on the PDCCH, obtain 2 dynamic channel resources in the corresponding UL PCC, that is, K=2; at this time, since K=(MN 0 ), it can be determined that S=K=2. The UE does not need semi-static channel resources. The UE can select a channel resource and a QPSK modulation symbol from the mapping table shown in Table 1-1 or Table 1-2, and ...
Embodiment 2
[0139] In the second embodiment, taking the number of bits of the response information as 3 bits as an example, the solution for allocating control channel resources in the technical solution of the present invention is described in detail. High-level signaling pre-configured N 0 =1, or the base station and UE pre-appoint N 0 = 1.
[0140] against Figure 7A , Figure 7B In the scenario shown, when the UE supports cross-carrier scheduling, that is, when the PDCCH on the DL PCC is cross-carrier scheduling, that is, when all data packets are scheduled from the PDCCH on the DL PCC, the UE can follow DL CC1 (the DL CC1 is DL PCC) on the PDCCH, obtain 2 dynamic channel resources in the corresponding ULPCC, namely K=2; at this time, since K=(MN 0 ), it can be determined that S=K=2, the number of semi-static channel resources required by the UE N=(MS)=1, that is, the UE needs 2 dynamic channel resources and 1 semi-static channel resource to feed back 3-bit response information; The stat...
Embodiment 3
[0145] In the third embodiment, taking the number of bits of the response information as 4 bits as an example, the solution for allocating control channel resources in the technical solution of the present invention is described in detail. High-level signaling pre-configured N 0 =1, or the base station and UE pre-appoint N 0 = 1.
[0146] against Figure 8A In the scenario shown, when the UE supports cross-carrier scheduling, that is, when the PDCCH on the DL PCC is cross-carrier scheduling, that is, when all data packets are scheduled from the PDCCH on the DL PCC, the UE can follow DL CC1 (the DL CC1 is DL PCC) on the PDCCH, obtain 2 dynamic channel resources in the corresponding UL PCC, namely K=2; at this time, K0 ), S=K=2, the number of semi-static channel resources required by the UE N=(MS)=2, that is, 2 dynamic channel resources and 2 semi-static channel resources are required for the UE to feedback 4-bit response information; the semi-static channel The resource can be dir...
