Description
Technical field
Method for transmitting signals, base in asymmetric carrier aggregation this application involves wireless communication field more particularly to one kind
It stands and user equipment.
Background technology
Asymmetric carrier aggregation refers to that up-link carrier and descending carrier have the carrier aggregation technology of unequal bandwidth.Non-
In symmetrical carrier aggregation technology, downlink component carrier quantity is typically larger than upstream components number of carrier wave, to be suitable for downlink business
Demand is more than the application scenarios of uplink service demand.Under asymmetric carrier aggregation scene, some component carriers have uplink and downlink
Transmittability, other component carriers only have downlink transfer ability, without uplink ability.For ease of description, below will
Component carrier with downstream transmission ability is known as uplink and downlink component carrier, and the component carrier of only downlink transfer ability is known as
Downlink component carrier.
Since directly uplink information cannot be sent to base station by downlink component carrier, it is therefore desirable to which cross-carrier scheduling is led to
Uplink information, such as channel state information could be sent with the associated uplink and downlink component carrier of downlink component carrier to receiving terminal by crossing
(Chanel State Information, CSI).In existing cross-carrier scheduling, the channel state measurement of downlink component carrier
Process approximately as：Downlink Control Information (Downlink Control Information, DCI) is sent to user and set by base station
It is standby, user equipment parsing DCI, when base station sends channel state measurement reference signal (Chanel on downlink component carrier
State Information-Reference Signal, CSI-RS) after, user equipment carries out channel status survey to CSI-RS
Amount, base station is reported on uplink and downlink component carrier by signal measurement result.
