Description

Transmission strengthens the method for schedule information, base station and subscriber equipment

Technical field

The present invention relates to the communications field, strengthen the method for schedule information, base station and subscriber equipment particularly to transmission in the communications field.

Such as, in 3GPPLTE standard, uplink and downlink data service all can use the transmission means of MU-MIMO, i.e. Physical Uplink Shared Channel (PhysicalUplinkSharedChannel, referred to as " PUSCH ") and Physical Downlink Shared Channel (PhysicalDownlinkSharedChannel, referred to as " PDSCH ") can be operated under MU-MIMO pattern, to alleviate the resource stressful situation when system load is heavier. But, base station needs schedule information by Physical Downlink Control Channel (PhysicalDownlinkControlChannel, referred to as " PDCCH ") notify scheduled subscriber equipment, when available resources total for PDCCH are certain and control channel information format is certain, there is a upper limit in the number of schedulable subscriber equipment. Therefore, although have employed some means strengthening frequency spectrum resource utilization ratio for PDSCH and PUSCH, but, the such enhancement method of such as MU-MIMO is all with the resource consumption increasing PDCCH for cost. In other words, when PDCCH resource is limited, it is impossible to adopt the such mode of MU-MIMO to improve frequency spectrum resource utilization ratio.

In order to strengthen the capacity of Physical Downlink Control Channel, it is possible to expand total available resources of PDCCH by taking the resource of PDSCH. But correspondingly, total available resources of PDSCH reduce so that system descending performance is subject to large effect. Other controls channel and there is resource-constrained problem too.

Therefore, how to strengthen the performance controlling channel, and the utilization ratio improving frequency spectrum resource is to be presently required to solve the technical problem that.

Subscriber equipment can pass through specific bit, distinguishes schedule information and interference information; Or subscriber equipment passes through respective identity identification information, distinguish schedule information and interference information. Subscriber equipment is according to schedule information and interference information, the advanced receivers technology such as such as non-linear receiver can be adopted, process the Physical Downlink Shared Channel PDSCH signal received such that it is able to improve the capacity of resisting disturbance of subscriber equipment, improve frequency spectrum resource utilization ratio; Or the schedule information according to this subscriber equipment and interference information, by such as Physical Uplink Shared Channel PUSCH uplink transmission data.

For given single schedule information, setting identification is M_RNTIThe transmission time of PDCCH be T1, it is T2 that subscriber equipment A, B detect the moment of this PDSCH, then subscriber equipment A and B detects PDCCH in the T1 moment, and according to the schedule information that the PDCCH detected comprises, carries out the detection of PDSCH in the T2 moment.

Should be understood that the embodiment of the present invention only illustrates for two subscriber equipment A and B, but the embodiment of the present invention is not limited to this. Such as, if three subscriber equipmenies A, B, C are in same community, their Physical Downlink Shared Channel resource is completely overlapped, then subscriber equipment A controls channel by detecting, and reads and is designated M_RNTIControl channel. By this control channel, subscriber equipment A can obtain base station and be sent to the enhancing schedule information of this subscriber equipment A.

Assume transmission time respectively T1, T2 of PDCCH, subscriber equipment A detects PDSCH in the T3 moment, wherein T1, T2, T3 meet: T1 < T2��T3 or T2 < T1��T3, so transmitting temporal difference according to the PDCCH schedule information content comprised, it is possible to use any one transmission means carries out the transmission of data by PDCCH below:

PDCCH transmission means one: PDCCH is in the schedule information that the transmission time T1 content comprised is subscriber equipment A, in the schedule information that the transmission time T2 content comprised is interference signal;

PDCCH transmission means two: PDCCH is a part for the schedule information of subscriber equipment A and a part for interference information in transmission time T1 and the T2 content comprised. Specifically, PDCCH in the transmission time T1 content comprised can be the schedule information of subscriber equipment A a part and interference information a part; PDCCH in the transmission time T2 content comprised can be the schedule information of subscriber equipment A remainder and interference information remainder.

Thus, subscriber equipment A can detect the content of the information of carrying on PDCCH at moment T1 and/or T2, and carry out the detection of PDSCH in the T3 moment.
