Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
In the LTE-A system, when the system information of component carrier A sent on well-behaved loading gage ripple A, sending method was with consistent in the LTE system; But when the system information of component carrier A does not send on well-behaved loading gage ripple A, should how to handle, technical scheme of the present invention will be described.
The present invention is directed to when configuration is expanded carrier wave or striden carrier dispatching in the LTE-A system, how the system information of component carrier sends on non-well-behaved loading gage ripple and receives the problem of handling, and has proposed the transmission method and the system of system information in carrier aggregation scene.The present invention is decomposed into this technical problem: select to adopt which or which component carrier to send described system information, and how on selected carrier wave, indicate the system information that sent system information for which component carrier, so that user equipment (UE) can be discerned, accurately obtain the system information of each component carrier.By the selected component carrier that sends, and accurately indicate system information corresponding to which component carrier, just can be implemented in the Downlink Control Information that sends other carrier system information on the carrier wave, thereby, the problem of obtaining of solution system information in carrier aggregation scene.

Component carrier by the selected transmitting system information in base station, the base station utilizes high-level signaling to pass through the 3rd layer of radio resource control layer (Radio Resource Control, abbreviate RRC as) indication information of selected component carrier is sent to one or more UE, UE resolves the indication information that high-level signaling obtains selected component carrier; The base station then sends the DCI of described system information on selected component carrier, UE is the DCI of detection system information on selected carrier wave then.
● give tacit consent to mode automatically
When PDCCH component carrier set pair has only one in UE, perhaps when expansion carrier wave B is only related with one-component carrier wave A, the former UE needs the DCI of system information of blind Detecting on unique component carrier A, latter UE needs the DCI of system information of expansion carrier wave B of blind Detecting on unique component carrier A, does not then need the high-level signaling indication this moment.
● selection mode at random
Can concentrate the DCI of the SI that selects any one component carrier send the expansion carrier wave or be striden the DCI of SI of the component carrier of carrier dispatching from the component carrier of PDCCH.For example, can concentrate optional one-component carrier wave A, be used to send the DCI of the system information of expanding carrier wave B from component carrier.
● the mode that on resident carrier wave, sends
During the system information of other component carriers beyond UE need obtain the component carrier collection of PDCCH, the DCI of these system informations sends on the descending resident carrier wave of UE.
In said method, the DCI that utilizes the RNTI of redetermination or contain the carrier wave indication information on selected component carrier determines the step of the pairing component carrier of DCI of system information to be sent, can by define a kind of have the wireless network temporary sign CI-RNTI of carrier wave indicative character or define a kind of new descending control information format DCI format realize.Wherein:

When the component carrier of carrier dispatching is striden in existence in the sub-district, dispose different CI-RNTI by high-level signaling to each component carrier of being striden carrier dispatching, select in the RNTI numerical value that the value of this CI-RNTI can be reserved from the LTE system, promptly comprise reserved value FFF3～FFFC, different component carriers has different CI-RNTI values, does not conflict with the RNTI of other kinds.
When the SI of component carrier B sends on this carrier wave B, the CRC that carries the DCI format 1A/1C of SI directly uses the SI-RNTI scrambling, when the DCI of the SI of component carrier B does not send on this carrier wave B, when for example on utilizing the selected component carrier A of above-mentioned four kinds of modes, sending, the CRC CI-RNTI scrambling of component carrier B of carrying the DCI format 1A/1C of SI.UE reaches the purpose of the system information of distinguishing different component carriers by descrambling verification DCI.
DCI format 1A definable with the CI-RNTI scrambling only is positioned at the common search space, maybe can be positioned at the proprietary search volume of common search space or UE.
DCI format 1C with the CI-RNTI scrambling only is positioned at the common search space.
● adopt the DCI format X indication that is specifically designed to other carrier waves of indication SI
