Therefore, the method of the control information transmission of the embodiment of the invention, control information by at least one UE of PDCCH signaling bear, thereby can be with the mode control information transmission of combined schedule, therefore can enlarge the capacity of control channel, save the expense of control channel, improve system call efficient and flexibility.

In S110, can divide into groups to subscriber equipment according to factors such as Link State, service related informations in the base station.For example, the base station can be divided into one group by the UE that downlink quality is close, also the UE that business burst is concentrated can be divided into one group, perhaps also can be divided into one group by the UE that traffic performance is close.Need to prove that the group technology of the actual employing in base station includes but not limited to that the method for foregoing description, base station can adopt a kind of method wherein, also can adopt wherein the partly or entirely combination of method.

Should be understood that when adopting specific method to divide into groups in the base station that can't continue to be in same group if one group UE is found to be divided in the base station, then the base station can re-start grouping to UE, and revises original grouping information again.

In S120, the base station sends RRC message to each interior subscriber equipment of the first grouping respectively, and this RRC message comprises the grouping information of this first grouping.For special user equipment, the grouping information that this RRC message comprises can be group sign and the position of this special user equipment in this first grouping of this first grouping.Be that the base station is different to the RRC message that the different user devices in dividing into groups sends.Alternatively, this RRC message can also comprise scheduling mode information, and this scheduling mode information is used to indicate the group scheduling mode that whether adopts the embodiment of the invention.

Should be understood that the position of subscriber equipment in grouping can comprise numbering or the relative position of subscriber equipment in grouping.Should also be understood that the RRC message for notice packet information, can be existing RRC message, and for example (RRC Connection Reconfiguration) message is reshuffled in the RRC connection, also can be the RRC message that increases newly.Can use some field in parameter, the parameter that increases newly or the existing parameter in the existing message and be used to indicate concrete transmission parameter in the grouping information.Should also be understood that the base station can send identical RRC message to the interior subscriber equipment of grouping, this RRC message comprises group sign of this first grouping, and the interior position of each subscriber equipment in this first grouping of this first grouping.

These RRC message and indication parameter only are for convenience of description and the title that adopts, this title can not limit the applicable scope of the embodiment of the invention, namely in some system, perhaps there is not similar title, but, can not think thus that the technical scheme in the embodiment of the invention can not be applicable to these systems.

In S130, suppose that the first grouping comprises N subscriber equipment, in current subframe, there be P subscriber equipment to be scheduled in this first grouping, at this moment, the base station can form a PDCCH signaling with the control information of this P scheduled user's equipment, and this PDCCH signaling has pre-configured magnitude of load, this magnitude of load is reserved according to the control information of M part, every part of control information in this M part control information is corresponding to a subscriber equipment, and N 〉=M 〉=P 〉=1, and wherein N, M, P are natural number.

In S140, the base station sends this PDCCH signaling by PDCCH to this at least one the scheduled user's equipment in this first grouping, thereby so that scheduled user's equipment can be according to the transmitting-receiving of control information to the enterprising row data of corresponding physical channel.

In embodiments of the present invention, alternatively, this PDCCH signaling also comprises scheduling identification, and whether each subscriber equipment that this scheduling identification is used in this first grouping of expression is scheduled.Preferably, this scheduling identification can identify with bit map, and the quantity of the bit that comprises of this scheduling identification equals the quantity of the subscriber equipment in this first grouping.Namely this scheduling identification can identify with bitmap (BitMap) mode of N bit, and the bit that is set to " 1 " or " 0 " can represent whether the subscriber equipment of corresponding sequence number is scheduled.Therefore, UE reads the scheduling identification of this N bit in the PDCCH signaling, and determines the scheduling identification of this UE according to the position of UE in this first grouping, and then determines whether this UE is scheduled in current subframe.

For example, as shown in Figure 2, when the first grouping comprises 8 subscriber equipmenies (N=8), and when in this first grouping of current subframe, 3 scheduled user's equipment (P=3) being arranged, this PDCCH signaling can comprise 8 scheduling identifications, wherein first three scheduling identification is set to " 1 ", and expression UE1, UE2 and UE3 are scheduled in current subframe.Thus, UE1, UE2 and UE3 can determine whether to be scheduled according to scheduling identification, and can determine the position in scheduled user's equipment, thereby can obtain corresponding control information.

In embodiments of the present invention, a PDCCH signaling has pre-configured magnitude of load, and this magnitude of load is reserved according to the control information of M part, and every part of control information is corresponding to a subscriber equipment.Alternatively, this M value adopts pre-configured value, or the value of this M value employing high-level signaling configuration, or this M value is along with the quantity dynamic change of scheduled user's equipment.

For example, as shown in Figure 2, the M value can adopt pre-configured value, and is set to M=4.This pre-configured value can be with reference to the quantity of the subscriber equipment in the grouping, and the quantity of the subscriber equipment that usually need to be scheduled in the same subframe and determining.

In embodiments of the present invention, this M value can adopt the value of high-level signaling configuration, for example this M value adopts the value by the RRC signal deployment, and should value also can be with reference to the quantity of the subscriber equipment in the grouping, and the quantity of the subscriber equipment that usually need to be scheduled in the same subframe and determining.At this moment, the quantity P of the subscriber equipment that is scheduled cannot surpass the M value, if P is then out vacant with the load of remainder less than the M value.

In embodiments of the present invention, this M value can be along with the quantity dynamic change of scheduled user's equipment.At this moment, because M value can dynamic change, thereby can support that the quantity of the subscriber equipment dispatched can be 1 to arrive N.Particularly, magnitude of load according to default PDCCH signaling, the variation of quantity along with the subscriber equipment of scheduling, pre-configured magnitude of load to this PDCCH signaling carries out different parsings, the mode of the granule size that for example can distribute by adjustresources, when the subscriber equipment of realizing varying number is scheduled to the parsing of the load of PDCCH signaling.For example, during the negligible amounts of the subscriber equipment of scheduling, can resolve the load of PDCCH signaling with less resource partition size; Otherwise adopt larger resource partition size.

Shown in Fig. 3 A and 3B, 4 subscriber equipmenies of same subframe scheduling have been shown among Fig. 3 A, the load of this PDCCH signaling is divided into 4 parts, i.e. M=P=4; Then show 2 subscriber equipmenies of same subframe scheduling among Fig. 3 B, the load of the formed objects of this PDCCH signaling is divided into 2 parts, i.e. M=P=2.Pass through thus the dynamically load of the control information of definite each subscriber equipment of carrying, can improve the level of resources utilization, and improve dispatching flexibility.

In embodiments of the present invention, alternatively, this control information that comprises in the PDCCH signaling is used for the transmission of data dispatching channel, or is used for the transmission of scheduling next stage control channel.This data channel for example is Physical Downlink Shared Channel (Physical Downlink Shared Channel, referred to as " PDSCH "), or Physical Uplink Shared Channel (Physical Uplink Shared Channel is referred to as " PUSCH ").This next stage control channel for example is next stage PDCCH, and this next stage PDCCH can be based on the precoding mode and transmit, and subscriber equipment comes this next stage of demodulation PDCCH based on UE specific reference signals (UE-specific Reference Signal).

Should be understood that next stage PDCCH is the PDCCH that carries the schedule information of data channel, the control information in the PDCCH signaling of group scheduling can be used to refer to the information such as resource distribution of this next stage PDCCH.

In embodiments of the present invention, alternatively, this PDCCH signaling also comprises the first resource allocation field that subscriber equipment exclusively enjoys, or the shared Secondary resource allocation field of subscriber equipment, this first resource allocation field or the carrying of this Secondary resource allocation field are used to indicate the information of the resource of distributing to this at least one scheduled user's equipment.

Particularly, the resource allocation information in the PDCCH signaling can be a plurality of subscriber equipmenies independently, or shared by a plurality of subscriber equipmenies.If the resource allocation information in the PDCCH signaling is carried on a plurality of UE independently in the resource allocation field, be that different UE has separately independently resource allocation field in this PDCCH signaling, in order to reduce the magnitude of load of PDCCH signaling, can adopt the resource distribution mode of simplification so.

For example, mode 1: be that resource of UE configuration is distributed set by the RRC signaling, the multiple resources method of salary distribution is arranged in this set, and again by the first resource allocation field in the PDCCH signaling, what notify dynamically that current this UE adopts is which mode in the multiple resources method of salary distribution in the set.Two kinds of concrete resource distribution modes are for example arranged, such as { RB1+RB2} and { RB3+RB4} then only needs 1 bit dynamically to notify this UE specifically to adopt any in this dual mode in the PDCCH signaling in the set of RRC signal deployment.

For example, mode 2: adopt continuous Resource Block (Resource Block is referred to as " the RB ") size of predefine or RRC signal deployment, and the position of adopting the concrete resource of resource allocation field indication UE in the PDCCH signaling to distribute.For example only distribute the resource of two continuous RB sizes for UE1, and always have 50 RB in the system, then only need log2 (50/2)=5 bit to notify concrete any two continuous RB among the PDCCH.

If the resource allocation information in the PDCCH signaling is carried in the public resource allocation field of a plurality of UE, each UE can adopt the predefined method of salary distribution, for example divides equally, and resolves resource allocation information separately.Perhaps each UE adopts the mode of multi-user (Multiple User is referred to as " MU ") multiple-input and multiple-output MIMO to resolve in the same a resource of notifying, and namely a plurality of UE share with a running time-frequency resource, and transmission is on the different layer of mimo channel.Especially, for the PDCCH signaling scheduling be next stage PDCCH, then a plurality of UE can the notice same a resource on blind Detecting next stage PDCCH.Namely the resource allocation information in the PDCCH signaling is in the situation that a plurality of UE shared, a plurality of UE read this resource allocation field jointly, obtain the resource collection of data channel, then according to predefined rule, in the resource collection of this data channel, determine the data channel resource of oneself.

In embodiments of the present invention, alternatively, this PDCCH signaling also comprises resource indication information, this resource indication information is used to indicate this at least one scheduled user's equipment uplink feedback and confirms that ACK/ denies the resource of nack message, or be used to indicate the resource of physical mixed automatic re-transmission indicating channel (Physical HARQ Indicator Channel is referred to as " PHICH ").

Particularly, mapping mode can be implicit expression or demonstration.Take up ACK/NACK as example, if adopt the implicit expression mapping, then can adopt control channel unit (the Control Channel Element of this PDCCH, referred to as " CCE ") label, corresponding ACK/NACK is starting point such as first CCE label that takies with this PDCCH, chooses successively a plurality of UE that a plurality of ACK/NACK distribute to scheduling with ACK/NACK channel label order from small to large; Show mapping if adopt, then can come its corresponding ACK/NACK resource of display notification with two bits respectively for each UE that is scheduled.

In embodiments of the present invention, the group sign of grouping can be running time-frequency resource, subframe numbers for example, frame number, timeslot number, the Resource Block label, the carrier wave label, position in the space, search volume etc., it also can be a yard territory resource, Radio Network Temporary Identifier (Radio Network Temporary Identity for example, referred to as " RNTI "), or space resources, such as antenna port etc., or the polywater equality of PDCCH, the group sign of this grouping can also be above-mentioned running time-frequency resource, code territory resource, the combination of one or more in the polymerization level of space resources and PDCCH.For example, different groupings identifies with different RNTI, and namely the UE of different grouping detects separately PDCCH signaling corresponding to grouping with RNTI corresponding to the group of UE separately; Perhaps, different groupings identifies with different detection subframes, detects corresponding PDCCH signaling such as the UE in the first grouping in the subframe of odd number, and the UE in the second grouping detects corresponding PDCCH signaling in the subframe of even number.

In embodiments of the present invention, alternatively, this RRC message also comprise group sign of at least one the second grouping under the first user equipment in this first grouping and this first user equipment at this position at least one second grouping.Namely a subscriber equipment belongs at least two groupings simultaneously, can greatly improve thus the flexibility of grouping, thereby improves the flexibility of group scheduling.

For example, as shown in Figure 4, UE1 is under the jurisdiction of simultaneously group and is designated the group of RNTI 0 and the group that group is designated RNTI 4, and this overlapping packet mode can improve the dispatching flexibility of group scheduling.Further, different group signs can also corresponding different antenna port informations.For example, UE can according to the PDCCH signaling that is designated RNTI 0 by group and detects, detect PDSCH or the next stage PDCCH of these PDCCH signaling schedulings at antenna port 7; UE can according to the PDCCH signaling that is designated RNTI 4 by group and detects, detect PDSCH or the next stage PDCCH of these PDCCH signaling schedulings at antenna port 8.

Should be understood that in embodiments of the present invention UE can at public search space, perhaps detect this PDCCH signaling in the search volume of group sign correspondence.If the employing public search space can increase the size that has public search space now, as being increased to 32 CCE from 16 CCE.Can limit on the other hand the polymerization level that this PDCCH signaling adopts that detects, as only with 2,4 and 8 three kind of polymerization level detect this PDCCH signaling.If UE has been configured the group sign of a plurality of RNTI, can also lengthen cyclic redundancy check (CRC) code (the Cyclical Redundancy Check of this PDCCH signaling, referred to as " CRC "), for example be increased to 18 or 20 from existing 16, to reduce the CRC false alarm probability.

Above in conjunction with Fig. 1 to Fig. 4, describe method according to the control information transmission of the embodiment of the invention in detail from the angle of base station, below in conjunction with Fig. 5 to Fig. 7, from the angle of subscriber equipment method according to the control information transmission of the embodiment of the invention is described.
