like Figure 5 (b) As shown in (d), if the scheduling subframe corresponding to the scheduled subframe is an uplink subframe according to the timing relationship, since the scheduling subframe is an uplink subframe, the grant cannot be sent, so scheduling cannot be performed

Embodiment Construction

[0039] A method for scheduling cross-carriers in carrier aggregation with different uplink and downlink ratios proposed by the present invention includes the following basic steps:

[0040] A judges whether the subframe of the scheduled component carrier is consistent with the uplink and downlink of the subframe corresponding to the scheduled component carrier, if yes, execute step B, otherwise, execute step C;

[0041] B. Scheduling the component carrier to perform cross-carrier scheduling on the subframe of the scheduled component carrier, and ending this process;

[0042] C. Set an e-PDCCH in the downlink subframe of the scheduled component carrier, and use the e-PDCCH to schedule the subframe of the scheduled component carrier.

[0043] The present invention is applicable to full-duplex scenarios. For the seven uplink and downlink subframe ratios of configuration 0-configuration 6, because the mixed ratio has a great impact on the specification and the complexity of the de...

Abstract

The invention discloses a method for dispatching crossed carriers in aggregation of carriers with different uplink and downlink proportions. The method comprises the following steps that: A whether the uplink and downlink of a subframe of a dispatched component carrier are consistent with those of a subframe of a dispatching component carrier is judged, if so, a step B is performed; otherwise, a step C is performed; B the dispatching component carrier performs crossed carrier dispatching on the subframe of the dispatched component carrier and ends the flow; and C an e-PDCCH (physical downlink control channel) is arranged in the downlink subframe of the dispatched component carrier and is used for dispatching the subframe of the dispatched component carrier. According to the scheme in the invention, the problem in the prior art that authority can not be sent out during the crossed carrier dispatching in aggregation of carriers with different uplink and downlink proportions is sovled.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to carrier aggregation technology, in particular to a cross-carrier scheduling method in carrier aggregation with different uplink and downlink ratios. Background technique [0002] In Long Term Evolution Time Division Duplex Release 10 (LTE-A TDD Release 10), the concept of carrier aggregation is introduced to support wider bandwidth transmission, that is, two or more carriers are aggregated together to support LTE-A transmission bandwidth greater than 20MHz transmission. For the carrier aggregation TD of Release10, only the intra-band scenario is supported. This frequency band (band) is the available wireless resource spectrum resource determined by the International Telecommunication Union. If different uplink and downlink ratios are used, the uplink and Severe interference occurs during downlink transmission and reception, so the aggregated component carrie...
