In order to improve the service efficiency of control channel, reduce the expense of control channel, and improve efficiency and the flexibility of system call, can divide into groups to subscriber equipment in base station, and tell each subscriber equipment by blocking message, when the transmission of control information carrying out scheduled user's equipment, the control information of at least one scheduled user's equipment can be formed a PDCCH signaling by base station, and send this PDCCH signaling by PDCCH, thus multiple subscriber equipment can be dispatched with a control signal, save control channel resource, improve the level of resources utilization.

Therefore, the method of the control information transmission of the embodiment of the present invention, by the control information of at least one UE of PDCCH signaling bear, thus can with the mode control information transmission of combined schedule, therefore, it is possible to expand the capacity of control channel, save the expense of control channel, improve system call efficiency and flexibility.

In S110, can divide into groups to subscriber equipment according to the factor such as Link State, service related information in base station.Such as, UE close for downlink quality can be divided into one group by base station, also the UE that business burst is comparatively concentrated can be divided into one group, or also UE close for traffic performance can be divided into one group.It should be noted that, the group technology of the actual employing in base station includes but not limited to the method for foregoing description, and base station can adopt a kind of method wherein, also can adopt the combination of wherein partly or entirely method.

Should be understood that when adopting specific method to divide into groups in base station, if base station finds that the UE being divided into a group cannot continue to be in same group again, then base station can re-start grouping to UE, and revises original grouping information.

In S120, base station sends RRC information respectively to each subscriber equipment in the first grouping, and this RRC information comprises the grouping information of this first grouping.For special user equipment, the grouping information that this RRC information comprises can be group mark and the position of this special user equipment in this first grouping of this first grouping.Namely the RRC information of base station to the different user devices transmission in grouping is different.Alternatively, this RRC information can also comprise scheduling mode information, and this scheduling mode information is used to indicate the group scheduling mode whether adopting the embodiment of the present invention.

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

These RRC information and indication parameter be only for convenience of description and adopt title, this title can not limit the scope that the embodiment of the present invention is suitable for, namely similar title is not perhaps had in some systems, but, can not think that the technical scheme in the embodiment of the present invention can not be applicable to these systems thus.

In S130, suppose that the first grouping comprises N number of subscriber equipment, in present sub-frame, there is P subscriber equipment to need to be scheduled in this first grouping, now, the control information of this P scheduled user's equipment can be formed a PDCCH signaling by base station, 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 corresponds to a subscriber equipment, and N >=M >=P >=1, wherein N, M, P are natural number.

In S140, base station sends this PDCCH signaling by PDCCH to this at least one the scheduled user's equipment in this first grouping, thus makes scheduled user's equipment can 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 this scheduling identification is for representing whether each subscriber equipment in this first grouping is scheduled.Preferably, this scheduling identification can identify by bit map, and the quantity of bit that this scheduling identification comprises equals the quantity of the subscriber equipment in this first grouping.Namely this scheduling identification can identify by the bitmap of N number of bit (BitMap) mode, and the bit being 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 number of bit in 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 at present sub-frame.

Such as, as shown in Figure 2, when the first grouping comprises 8 subscriber equipmenies (N=8), and when having 3 scheduled user's equipment (P=3) in this first grouping of present sub-frame, this PDCCH signaling can comprise 8 scheduling identifications, wherein first three scheduling identification is set to " 1 ", represents that UE1, UE2 and UE3 are scheduled at present sub-frame.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, thus 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 corresponds to a subscriber equipment.Alternatively, this M value adopts pre-configured value, or the value that this M value adopts high-level signaling to configure, or this M value changes along with the Number dynamics of scheduled user's equipment.

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

In embodiments of the present invention, the value that this M value can adopt high-level signaling to configure, such as this M value adopts the value by RRC signal deployment, and this value also with reference to the quantity of the subscriber equipment in a grouping, and can need the quantity of the subscriber equipment be scheduled in same subframe and determine usually.Now, the quantity P of the subscriber equipment be scheduled cannot more than M value, if P is less than M value, then by out vacant for the load of remainder.

In embodiments of the present invention, this M value can change along with the Number dynamics of scheduled user's equipment.Now, because M value can dynamic change, thus can support that the quantity of the subscriber equipment dispatched can be 1 to N.Particularly, according to the magnitude of load of the PDCCH signaling preset, along with the change of the quantity of the subscriber equipment of scheduling, different parsings is carried out to the pre-configured magnitude of load of this PDCCH signaling, the mode of the granule size that such as can be distributed by adjustresources, the parsing to the load of PDCCH signaling when the subscriber equipment realizing varying number is scheduled.Such as, during the negligible amounts of the subscriber equipment of scheduling, can resolve by the load of less resource allocation granularity to PDCCH signaling; Otherwise adopt larger resource allocation granularity.

As shown in figs.3 a and 3b, same subframe scheduling 4 subscriber equipmenies have been shown in Fig. 3 A, and the load of this PDCCH signaling is divided into 4 parts, i.e. M=P=4; Then show same subframe scheduling 2 subscriber equipmenies in Fig. 3 B, the load of the formed objects of this PDCCH signaling is divided into 2 parts, i.e. M=P=2.Thus by dynamically determining the load of the control information carrying each subscriber equipment, can the level of resources utilization be improved, and improve dispatching flexibility.

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

Should be understood that next stage PDCCH is used to the PDCCH of the schedule information carrying data channel, the control information in the PDCCH signaling of group scheduling can be used to refer to the information such as the Resourse Distribute 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 Secondary resource allocation field that subscriber equipment shares, this first resource allocation field or the carrying of this Secondary resource allocation field are used to indicate the information of the resource distributing to this at least one scheduled user's equipment.

Specifically, the resource allocation information in PDCCH signaling can be multiple subscriber equipment independently, or to be shared by multiple subscriber equipment.If the resource allocation information in PDCCH signaling is carried on multiple UE independently in resource allocation field, namely different UE has separately independently resource allocation field in this PDCCH signaling, so in order to reduce the magnitude of load of PDCCH signaling, the resource distribution mode of simplification can be adopted.

Such as, mode 1: be that UE configures a Resourse Distribute set by RRC signaling, have the multiple resources method of salary distribution in this set, then by the first resource allocation field in PDCCH signaling, what notify that this UE current adopts dynamically is which mode in the multiple resources method of salary distribution in set.Such as, there is the resource distribution mode that two kinds concrete in the set of RRC signal deployment, as { RB1+RB2} and { RB3+RB4}, then only needing 1 bit in PDCCH signaling, that this UE of dynamic notification specifically adopts in these two kinds of modes is any.

Such as, mode 2: continuous print Resource Block (Resource Block, referred to as " the RB ") size adopting predefine or RRC signal deployment, and the position of the Resourse Distribute adopting the resource allocation field in PDCCH signaling to indicate UE concrete.Such as UE1 only distributes the resource of two continuous RB sizes, and in system, always have 50 RB, then only need log2 (50/2)=5 bit to notify concrete any two continuous print RB in PDCCH.

If the resource allocation information in PDCCH signaling is carried in the public resource allocation field of multiple UE, each UE can adopt the predefined method of salary distribution, such as, divide equally, and resolves respective resource allocation information.Or each UE adopts multi-user (Multiple User in notified same a resource, referred to as " MU ") mode of multiple-input and multiple-output MIMO resolves, namely multiple UE shares with a running time-frequency resource, transmits on the different layer of mimo channel.Especially, for PDCCH signaling scheduling is next stage PDCCH, then multiple UE can notice same a resource on blind Detecting next stage PDCCH.Namely the resource allocation information in PDCCH signaling by multiple UE shared, multiple UE reads 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, referred to as " PHICH ").

Specifically, mapping mode can be implicit expression or display.For up ACK/NACK, if adopt implicit expression to map, then can adopt control channel unit (the Control Channel Element of this PDCCH, referred to as " CCE ") label, the ACK/NACK that first the CCE label such as taken with this PDCCH is corresponding is starting point, chooses with ACK/NACK channel label order from small to large multiple UE that multiple ACK/NACK distributes to scheduling successively; If adopt display to map, then can show for each UE be scheduled the ACK/NACK resource notifying its correspondence respectively with two bits.

In embodiments of the present invention, the group mark of grouping can be running time-frequency resource, such as subframe numbers, frame number, timeslot number, Resource Block label, carrier wave label, position etc. in space, search volume, also can be code domain resource, such as Radio Network Temporary Identifier (Radio Network Temporary Identity, referred to as " RNTI "), or space resources, such as antenna port etc., or the polywater equality of PDCCH, the group mark of this grouping can also be above-mentioned running time-frequency resource, code domain resource, the combination of one or more in the polymerization level of space resources and PDCCH.Such as, the different RNTI of different groupings identifies, and namely the UE of different grouping detects with the RNTI that respective UE group is corresponding the PDCCH signaling that grouping is corresponding separately; Or the different detection subframe of different groupings identifies, as the UE in the first grouping detects corresponding PDCCH signaling in the subframe of odd number, 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 information also comprises group mark and the position of this first user equipment at this at least one second grouping of at least one the second grouping belonging to first user equipment in this first grouping.Namely a subscriber equipment belongs at least two groupings simultaneously, greatly can improve the flexibility of grouping thus, thus improves the flexibility of group scheduling.

Such as, as shown in Figure 4, UE1 is under the jurisdiction of group simultaneously and is designated the group that the group of RNTI 0 and group are designated RNTI 4, and this overlapping packet mode can improve the dispatching flexibility of group scheduling.Further, all right corresponding different antenna port information of different group marks.Such as, UE according to the PDCCH signaling being designated RNTI 0 by group and detecting, antenna port 7 can detect PDSCH or the next stage PDCCH of this PDCCH signaling scheduling; UE according to the PDCCH signaling being designated RNTI 4 by group and detecting, antenna port 8 can detect PDSCH or the next stage PDCCH of this PDCCH signaling scheduling.

Should be understood that in embodiments of the present invention, UE at public search space, or can detect this PDCCH signaling in the search volume of group mark correspondence.If employing public search space, the size of existing public search space can be increased, as being increased to 32 CCE from 16 CCE.The polymerization level detecting this PDCCH signaling and adopt can be limited on the other hand, as only use 2,4 and 8 three kind of polymerization level to detect this PDCCH signaling.If UE has been configured the group mark of multiple RNTI, cyclic redundancy check (CRC) code (the Cyclical Redundancy Check of this PDCCH signaling can also be lengthened, referred to as " CRC "), be such as increased to 18 or 20 from existing 16, to reduce CRC false alarm probability.
