The embodiment of the invention provides a kind of downlink control information transmission method, and as shown in Figure 6, this method comprises:

601, network side is determined the receiving mode of subscriber equipment control channel, and chooses the receiving mode corresponding district with described subscriber equipment control channel; Wherein, the receiving mode of described subscriber equipment control channel is to receive or receive from the control channel of at least two sub-districts from the control channel of a sub-district, the receiving mode of the subscriber equipment control channel that network side is determined can be distinguished in the following manner, for example: the receiving mode that defines the subscriber equipment control channel with the data of 1 bit, when the numerical value of 1 bit is " 0 ", represent that described receiving mode receives for the control channel from a sub-district; When the numerical value of 1 bit is " 1 ", represent that described receiving mode receives for the control channel from least two sub-districts.

602, network side is with the receiving mode of definite subscriber equipment control channel, and with the sign of the receiving mode corresponding district of described subscriber equipment control channel, send to described subscriber equipment by the current sub-district that sends Downlink Control Information for described subscriber equipment.

603, subscriber equipment receives the receiving mode of network side by the subscriber equipment control channel of down control channel transmission, judges that described receiving mode is the control channel reception from a sub-district, and still the control channel from least two sub-districts receives; If subscriber equipment detects the subscriber equipment control channel receiving mode that is provided with on the down control channel when receiving for the control channel from a sub-district, for example: the receiving mode of control channel is labeled as " 0 ", the receiving mode that the expression network side is provided with is the control channel reception from a sub-district, then forwards step 604 to; When if the receiving mode that subscriber equipment detects the subscriber equipment control channel that is provided with on the down control channel receives for the control channel from least two sub-districts, for example: the receiving mode of control channel is labeled as " 1 ", the receiving mode that the expression network side is provided with forwards step 606 to for receiving the control channel of at least two sub-districts.

604, subscriber equipment receives the sign of a described sub-district of network side transmission, the identification means that receives described sub-district has following two kinds: first kind, when network side is carried at the sign of a described sub-district in the down control channel of current main Serving cell of subscriber equipment when sending to corresponding subscriber equipment simultaneously with determined receiving mode, directly in the down control channel that receives current main Serving cell, receive the sign of a described sub-district; Second kind, when network side sent to corresponding subscriber equipment with the sign of a described sub-district by high-level signaling, subscriber equipment obtained the sign of a described sub-district by analyzing high-level signaling.

605, from the down control channel of the sign corresponding district of a described sub-district that receives, receive Downlink Control Information, and finish the process of this Downlink Control Information transmission.

606, receive the sign of described at least two sub-districts of network side transmission, the label manner of described at least two sub-districts of described reception is identical as the dual mode in the step 604.

607, subscriber equipment judges whether to receive the sign of described at least two sub-districts that network side sends, if do not receive the sign of described at least two sub-districts of network side transmission, forward step 608 to, if subscriber equipment receives the sign of described at least two sub-districts that network side sends, forward step 609 to.

608, subscriber equipment is from Active Set (candidate set, the physical layer measurement result reports set, Activeset, Candidate CoMP set) receives Downlink Control Information in the down control channel of the whole sub-districts that comprise, and finish the process of this Downlink Control Information transmission.

609, subscriber equipment receives Downlink Control Information from the down control channel of described at least two cell ID corresponding district that receive, and finishes the process of this Downlink Control Information transmission.

Wherein, network side apparatus determines that the receiving mode of subscriber equipment control channel can adopt but is not limited to following dual mode in the step 601:

First kind, network side whether greater than the predetermined speed threshold value, is judged the receiving mode with described subscriber equipment control channel according to described subscriber equipment present speed, and described predetermined speed threshold value can be an empirical value, as 150Kmh; When described subscriber equipment present speed was not more than the predetermined speed threshold value, network side judged that the receiving mode of the control channel of described subscriber equipment receives for the control channel from a sub-district; During greater than the predetermined speed threshold value, network side judges that the receiving mode of the control channel of described subscriber equipment receives for the control channel from least two sub-districts at described subscriber equipment present speed.

Second kind, whether network side judges the receiving mode of subscriber equipment control channel greater than predetermined quality threshold value according to the residing quality of subscriber equipment, when the residing quality of subscriber equipment during greater than predetermined quality threshold value, be the residing quality situation of described subscriber equipment when better, network side judges that the receiving mode of the control channel of described subscriber equipment receives for the control channel from a sub-district; When the described quality of subscriber equipment during less than predetermined quality threshold value, when the residing quality situation of promptly described subscriber equipment was relatively poor, network side judged that the receiving mode of the control channel of described subscriber equipment receives for the control channel from least two sub-districts.Wherein, described predetermined quality threshold value is an empirical value, can determine according to actual conditions.

Wherein, will identify with the receiving mode corresponding district of described control channel in the step 603, send to corresponding subscriber equipment, be implemented as follows by current sub-district for subscriber equipment transmission Downlink Control Information:

First, when described receiving mode is when the control channel of a sub-district receives, the mode that a described cell ID is sent to described family equipment has following three kinds: first kind, network side sends to described subscriber equipment by high-level signaling with the sign of a described sub-district; Second kind, network side is carried at the sign of a described sub-district in the down control channel of current main Serving cell of described subscriber equipment and sends to described subscriber equipment; The third, network side and user equipment side setting just as the rule of acquiescence, described default rule is specially: when receiving mode that the receiving mode of subscriber equipment receives for the control channel from a sub-district, the network side acquiescence is that described subscriber equipment sends Downlink Control Information by the current main Serving cell of described subscriber equipment.Correspondence is planted mode therewith, and when described subscriber equipment received from the receiving mode of the control channel of the control channel reception of a sub-district, acquiescence received Downlink Control Information from the control channel of the current main Serving cell of described subscriber equipment.

Wherein, the described sub-district of the sending method of first kind and second kind sub-district can be current main Serving cell of subscriber equipment or the maximum sub-district of received power (RSRP), perhaps maximum sub-district or minimum sub-district or the less sub-district of business load of path loss (PathLoss) of receiving intensity (RSRQ).

Second, when described receiving mode is when the control channel of at least two sub-districts receives, the mode that the sign of described at least two sub-districts is sent to described subscriber equipment has following three kinds: first kind, when not distinguishing described at least two sub-districts and be whole sub-districts in the Active Set or part sub-district, the sign of described at least two sub-districts is carried in the down control channel of current main Serving cell of described subscriber equipment and send to described subscriber equipment;

Second kind, when distinguishing described at least two sub-districts and be whole sub-districts in the Active Set or part sub-district, the part sub-district that receives in the described Active Set by the high-level signaling notifying user equipment still is whole sub-districts, when if described at least two sub-districts are whole sub-district in the Active Set, only determined receiving mode is sent to described subscriber equipment, described subscriber equipment is with regard to the reception Downlink Control Information in the down control channel of whole sub-districts of acquiescence from described Active Set; When if described at least two sub-districts are part sub-district in the Active Set, the sign of described at least two sub-districts is carried in the down control channel of current main Serving cell of described subscriber equipment and send to described subscriber equipment, described subscriber equipment just can receive Downlink Control Information from the down control channel of the sign corresponding district of described at least two sub-districts of receiving.

The third, the rule that acquiescence is set is: when the receiving mode of described subscriber equipment was defined as from receiving mode that the control channel of at least two sub-districts receives, the network side acquiescence was that subscriber equipment sends Downlink Control Information by the whole sub-districts in the Active Set.Correspondence is planted mode therewith, when described subscriber equipment receives from the receiving mode that the control channel of at least two sub-districts receives, receives Downlink Control Information in the down control channel of whole sub-districts of acquiescence from Active Set.

When the receiving mode of subscriber equipment when from the control channel of at least two cell downlinks, receiving, Active Set upgrades the Downlink Control Information of the reception cell downlink control channel that can guarantee that subscriber equipment is correct timely.Unite the performance that sends and receive in order to improve, the embodiment of the invention also comprises the renewal of Active Set, and for the activating set updating reported result, the highspeed user reduces reporting range, make the easier reporting range that enters in sub-district that Active Set is outer, and measurement result is reported network side.Easier adding Active Set guarantees the real-time update that set collects.For low speed user, do not need too frequent activating set updating, thereby can be for the activating set updating reported result, low speed user improves reporting range, makes the sub-district reporting range more difficult to get access that Active Set is outer, and measurement result is reported network side.The more difficult adding Active Set in sub-district that Active Set is outer.Concrete renewal process comprises as shown in Figure 7:

701, obtain the subscriber equipment present speed corresponding speed factor, described velocity factor high speed velocity factor or middling speed velocity factor or low speed velocity factor.

702, upgrade described reporting range constant according to described velocity factor and standard report scope constant.Wherein said new reporting range constant comprises:

The first, if the current velocity factor of the described subscriber equipment that obtains is the high speed velocity factor, then described new reporting range constant is: R1a* high speed velocity factor, R1b* high speed velocity factor or R1a-high speed velocity factor, R1b-high speed velocity factor; Wherein R1a is the reporting range constant that a sub-district enters reporting range, and R1b is the reporting range constant that reporting range is left in a sub-district;

The second, if the current velocity factor of the described subscriber equipment that obtains is the middling speed velocity factor, then described new reporting range constant is: R1a* middling speed velocity factor, R1b* middling speed velocity factor or R1a-middling speed velocity factor, R1b-middling speed velocity factor;

The 3rd, if the current velocity factor of the described subscriber equipment that obtains is the high speed velocity factor, then described new reporting range constant is: R1a* low speed velocity factor, R1b* low speed velocity factor or R1a-low speed velocity factor, R1b-low speed velocity factor.

703, upgrade described Active Set according to the reporting range constant after the described renewal.For example, when obtaining the current velocity factor of subscriber equipment and be high speed, as new report constant, sub-district of substitution enters the formula of reporting range with R1a* high speed velocity factor or R1a-high speed velocity factor, and the judgement of carrying out the Target cell quality realizes the renewal of Active Set; As new report constant, the formula of reporting range is left in sub-district of substitution with R1b* high speed velocity factor or R1b-high speed velocity factor, and the judgement of carrying out the Target cell quality realizes the renewal of Active Set.

Further, because it is less to be in the influence of the suffered speed of renewal of subscriber equipment Active Set of middling speed or low speed, so the Active Set to the subscriber equipment correspondence that is in low speed or medium velocity state upgrades, and can carry out the renewal of corresponding Active Set according to the reporting range constant of standard.
