Description

Control information sending and receiving method and control information transmission and receiving system

Technical field

The present invention relates to the communications field, and more particularly, relate to the sending and receiving method of a kind of MAC-hs (high speed media access control) control information, and the transmission of MAC-hs control information and receiving system.

Background technology

3GPP (third generation partner program) system is divided into UE (User Equipment, subscriber equipment), UTRAN (UMTS Terrestrial Radio Access Network, UMTS system ground Radio Access Network) and three parts of CN (Center Network, core net).

The interface of UE and UTRAN is the Uu interface, and the function of wireless access subscriber is provided.The protocol stack of Uu interface comprises RRC (Radio ResourceControl successively from the upper strata to the lower floor, Radio Resource control), RLC (Radio Link Control, Radio Link control), agreements (this is the protocol stack of control aspect) such as MAC (Medium Access Control, medium access control) and physical layer.The RRC agreement provides the signaling plane of Uu interface to connect, and is used for the high-rise control of transmission signaling between UTRAN and UE.UTRAN is divided into RNC (Radio Network Control, radio network controller) and two network elements of Node B (Node B).RNC control Node B, the protocol function of realization RRC/RLC/MAC.Node B realizes the function of part MAC and the protocol function of radio physical layer.

From version 5,3GPP provides HSDPA (high speed downlink packet access mechanism), is used to provide the downlink grouped high-speed transfer of interface aloft.After introducing HSDPA, the protocol stack of eat dishes without rice or wine (Uu interface) has increased the MAC-hs sublayer.Its protocol stack structure wherein, only shows the protocol stack of control aspect as shown in Figure 1 among Fig. 1.MAC-d shown in Fig. 1 is the sublayer of MAC, is called special-purpose MAC.It provides the service of dedicated logical channel to rlc layer.Iub interface is the interface between Node B and the RNC.RNC sends the MAC-d data block by HS-DSCH FP agreement to Node B and handles to the MAC-hs protocol entity, is configured to MAC-hs PDU by the MAC-hs protocol entity and sends on the HS-DSCH channel.L2/L1 is transport network layer 2 and the transport network layer 1 for HS-DSCH FP service.MAC-hs layer in Node B is realized functions such as HSDPA (HighSpeed Downlink Packet Access, high speed downlink packet inserts) scheduling of resource and quick affirmation re-transmission.

HSDPA is interacted by high-speed downlink shared transmission channel (HS-DSCH), high-speed downstream Physical Shared Channel (HS-PDSCH), downlink high-speed shared control channel (HS-SCCH) and HS-DSCH dedicated uplink physical control channel (HS-DPCCH) and realizes.The characteristic of channel of HS-SCCH, HS-DPCCH and HS-DSCH, all dispose to UE by the RRC signaling when setting up at radio bearer (Radio Bearer) by RNC, RNC also distributes an identifier H-RNTI to give this UE simultaneously, is used for identifying on the HS-SCCH channel this UE.

HS-DSCH is a transmission channel, carrying MAC-hs PDU on it.It is mapped to physical channel HS-PDSCH and goes up transmission.The HS-DSCH frame structure is (3GPP existing protocol version 5 and 6) as shown in Figure 2.

In Fig. 2, Queue ID is queue identity (UE can have 8 formations at most); TSN is a transmission sequence number, is used to represent the serial number of present frame, if the TSN of former and later two frames is identical, shows that then back one is previous retransmission frame; SID represents the length information of corresponding serial MAC-d PDU and multiplexing logic channel on it, N represents the number of the serial MAC-d PDU of this length, F represents whether be the sign of data, if F=0, then expression is thereafter MAC-hs head (MAC-hs Header), if F=1 then is thereafter the carrying (MAC-hs payload) of MAC-hs, head just finishes.Wherein, Mac-hs SDU is exactly MAC-d PDU.Padding fills, and possible MAC-hs PDU is long, but does not have enough SDU to fill up, and therefore fills up whole PDU with some insignificant data, is called filling.

In the evolution of new generation of 3GPP (HSPA evolution), the frame structure of HS-DSCH may have very big variation, can be structure shown in Figure 3, certainly, also can be other form.In Fig. 3, LCH ID is a logical channel identifier, is used to identify corresponding MAC-hs SDU and belongs to which logic channel; LI is the length of the MAC-hs SDU of correspondence; F=0 represent immediately following thereafter be the MAC-hs head, F=1 then represents immediately following being MAC-hs SDU thereafter.

From version 6,3GPP has introduced HSUPA (high speed uplink packet access) agreement, is used to provide the transmission of upstream packet at a high speed.It also is made up of descending E-AGCH physical channel (absolute grant channel of enhancing), E-RGCH physical channel (the relative authorization channel of enhancing), E-DPCCH physical channel (Dedicated Physical Control Channel of enhancing), E-DPDCH physical channel (dedicated data channel of enhancing), E-HICH (the hybrid ARQ indicating channel of enhancing) and E-DCH transmission channel (dedicated channel of enhancing).Wherein, E-AGCH and E-RGCH are by the down physical channel of Node B control, are used to send schedule information.E-DPCCH, E-DPDCH, E-DCH are by the up channel of UE control, are used to send upstream data.Node B uses E-HICH to send replying the Data Receiving situation on the E-DCH.

The channel of UE and the configuration of other various resources are all given UE by network (specifically referring to UTRAN) scheduling configuration concurrency.Network is by the behavior of configuration signal or dispatch control UE.In present 3GPP standard, the method for the network control UE that is adopted mainly contains two kinds: a kind of is to send to UE by the message with rrc layer to control; Another kind is by the signaling of physical layer UE to be controlled, for example, HS-SCCH, E-AGCH, E-RGCH channel, this part signaling is the resource scheduling information that changes very fast HSDPA/HSUPA.

In the mode of controlling by the signaling of rrc layer, RRC structure RRC message, and by becoming the SDU of MAC-hs after RLC, the MAC-d processing, by MAC-hs with other business datum (such as speech VoIP data etc.), non-signaling data scheduled transmission together, MAC-hs does not also know that it is a RRC message, and also message content not being operated, only is to be used as general data to send to UE.This control mode is very flexible, because the content of message and form can be diversified, and is easy to expansion, as long as carry out respective handling after the UE end is by the rrc layer decoding.But it is slow that its shortcoming is a control rate, because need processing and transmission through a lot of layers, and processing and transmission can be introduced corresponding time delay, and dispatch at MAC-hs, and the time of scheduling can't well be guaranteed.So the message of this part is that the general information that can often not change such as the channel parameter among the UE (such as the sign indicating number of physical channel, the data block of transmission channel, the multiplexed information of logic channel) are controlled substantially.

Control mode by the physical channel signaling, in agreement, define fixing physical channel form, and generally have only a kind of form (may have multiple, but implement more complicated, this is because UE need carry out blind decoding in physical layer, generally can be above 3 kinds).Because directly handle in physical layer, can send at any time by physical channel, therefore this control mode speed is very fast.Need take special-purpose Radio Resource (Radio Resource is limited) but its shortcoming is a physical channel, and channel format fixes, be difficult to expansion, control dumb.So, the general control of this part signaling be that content change is very fast, and the information used of physical layer such as the fixing resource scheduling information of form or MAC-hs layer.

Companies such as high pass, Nokia, Ericsson propose in R1-062680 and R1-062996, and UE need be used for the network scheduling downlink resource to network-reporting down channel CQI value (channel quality indication).Because (multiple-input and multiple-output adopts 2 * 2 in the HSPA evolution, promptly at present to have adopted the MIMO technology in the HSPA of 3GPP evolution standard, two inputs, two outputs), UE need be to two kinds of CQI of network-reporting, and a kind of is that single input list is exported, and another kind is two inputs, two outputs.These two kinds of CQI values but are reported on different frames on same uplink special physical channel in turn, and the report frequency of these two kinds of CQI is different with number of times, and the number of times of its report and frequency are given UE by network configuration.The frequency and the number of times of two kinds of CQI reports by three parameter decisions, are referred to as the CQI control information here, and these three parameters are respectively the distribution factor N/M of CQI k reporting period, CQI repetition factor N_cqi_transmit, two kinds of CQI reports.In R1-062680, the above-mentioned CQI control information that the message of regulation by rrc layer will dispose sends to UE, and UE sends CQI according to these three parameters and reports.

Network side can be adjusted above-mentioned three configuration parameters according to the difference (such as area interference level, data traffic etc.) of various states in the sub-district, and usually, judge whether to need to adjust and determine how these three parameters are set (certainly in specific implementation by MAC-hs layer protocol entity, can not adjust yet, perhaps decide adjustment, but need MAC-hs layer or other layers that corresponding information is reported to rrc layer as foundation by rrc layer.But adjusting and being made decisions by the MAC-hs layer is reasonable realization, and making decision with the MAC-hs layer here is that example is discussed).So, after making decisions, MAC-hs (produces the CQI control information), need notify rrc layer with the result of decision, rrc layer is configured to RRC message to comprise this three configuration parameters with the CQI control information, after the protocol processes by RLC/MAC-d layer etc., arrive the MAC-hs layer, by the MAC-hs layer it is dispatched with other data and send to UE.The processing procedure of CQI control information is shown in Figure 4.

As shown in Figure 4, the CQI control information that MAC-hs produces need be delivered to rrc layer, is configured to RRC message (including the CQI control information in this message) by rrc layer; RRC message is handled through RLC, and wherein, RLC can be divided into a plurality of bursts with this RRC message, and is configured to RLC PDU respectively, and afterwards at the MAC-d layer, each RLC PDU is configured to MAC-d PDU after adding the MAC-d head.At last, MAC-d PDU is sent by MAC-hs scheduling, and MAC-hs does not also know content among the MAC-d PDU of own processing.

In addition, in HSPA evolution, adopt MIMO (multiple-input and multiple-output) technology.MIMO has multiple mode of operation.Different UE can work in different MIMO patterns.This is to be selected according to features such as the quality of wireless channel of UE, data traffics by the MAC-hs of network side or physical layer.Network side need be notified UE.Present technology is to adopt the form notice UE of RRC signaling, and this just causes aforesaid shortcoming equally.When physical layer and MAC-hs layer are in Node B, and rrc layer is when being positioned at RNC, and problem is just even more serious.

This shows that the result of decision of MAC-hs layer need send to rrc layer, send it back the MAC-hs layer after handling by rrc layer again, send by the scheduling of MAC-hs layer.This has caused the system handles complexity, and control rate waits problem slowly.

Therefore, in technical scheme described above, owing to need between different layers even different network elements, come transmission back information, dispatch transmission by the MAC-hs layer more at last, caused system handles complexity, control rate slow, directly reduced systematic function in addition.

Another technical scheme related to the present invention is, companies such as Ericsson propose in R1-062877, owing in HSPA evolution, introduce MIMO technology (2 * 2), thus between a plurality of antennas, share same channelization codes, caused interference, it is inaccurate to cause UE to measure CQI.

For the problems referred to above, a kind of solution of proposition is, sets up an independent down physical channel, by network the supplementary that CQI measures sent to corresponding UE.For different UE, because the state difference of UE (for example, the quality of wireless channel of different UEs, data traffic etc. are all different), so the supplementary that CQI measures is also different.Because down physical channel need occupy a yard resource, so can not notify supplementary for each UE sets up a down physical channel.Solution to this is only to set up a physical channel, but UE is divided into groups, and the UE of different conditions assigns to different groups, like this by a physical channel, sends supplementary in turn different groups.But, owing to the state of UE is constantly to change, the therefore maintenance of group very difficult (because the state of UE changes, need its group of notice UE to change, this will bring very a large amount of notification messages, and system is impacted).And the frame structure of physical channel is relatively more fixing (if unfixing, UE will not know how to decode, though multiple frame format can be arranged, UE need carry out blind decoding, this can increase processing complexity and the processing speed of UE, so a variety of frame formats can not be arranged).

So, control (for example, the supplementary that transmission CQI measures) by the physical channel frame, even under the situation that does not have the signaling transmission, also need to take fixing sign indicating number resource, this will cause yard resource waste, control inflexible problem.

Summary of the invention

Consider that the control information that there is network side in present technical scheme gives UE speed slow and handle complicated problems by the RRC transmission of messages, and dumb and problem that be difficult to expand is made the present invention by physical channel control UE.

Embodiment

Describe embodiments of the invention hereinafter with reference to accompanying drawing, should be appreciated that provides following examples so that further understand and implement the present invention, rather than the present invention is carried out any restriction.

Method embodiment one

In the present embodiment, provide a kind of control information sending method.

As shown in Figure 5, this control information sending method may further comprise the steps: step S502, and the high speed media access control of network side (MAC-hs) protocol entity generates the control information of high speed media access control (MAC-hs); Step S504, MAC-hs protocol entity structure high speed media access control protocol Data Unit (PDU, Protocol Data Unit) wherein carries control information; And step S506, the MAC-hs protocol entity will send to subscriber equipment (UE) among the MAC-hsPDU.

It should be noted that at first above-mentioned control information is a generalized concept, it can include but not limited to following content: control information, signaling information, command information, management information, control messages, signaling message etc.And above-mentioned control information can be following any or its combination: MIMO mode control information, channel quality indication control information, channel quality indication measurement supplementary, the control information of channel quality indication report pattern.

In addition, the MAC-hs PDU that relates among the above-mentioned step S504 carries control information can be divided into two kinds of situations, that is, and directly bear control information or bear control information indirectly.Wherein, directly bear control information is meant control information is configured to MAC-hs PDU that this MAC-hs PDU is called the PDU of bear control information; And indirect bear control information is meant control information is configured to MAC-hs SDU that this MAC-hs SDU is encapsulated in MAC-hs PDU, this MAC-hs SDU is called the SDU of bear control information again.Below will be described this respectively.

(1) PDU of bear control information

At this moment, the MAC-hs protocol entity carries identification information in downlink high-speed shared control channel, whether carries control information in order to indicate corresponding MAC-hs PDU; Perhaps the MAC-hs protocol entity carries the number identification information in downlink high-speed shared control channel, in order to indicate the number of the control information that corresponding MAC-hs PDU carried.

Perhaps, if in high speed descending sharing channel, do not carry identification information, can in the head of the PDU of bear control information, carry at least one in the following information: type identification information, whether be used to identify its corresponding PDU is the PDU of bear control information; Control information number identification information is used to identify the number of control information of the PDU carrying of bear control information; Control information length mark information is used to identify PDU carried and the length this control information length mark information control information corresponding of bear control information.The embodiment of the invention provides this MAC-hs control information directly is configured to MAC-hsPDU, and in head the sign wherein carry be control information the PDU structure as shown in Figure 6, in Fig. 6, whether the CIF sign is the PDU of bear control information, if CIF=1, show that this PDU is the PDU of bear control information, otherwise be not; The control information number of carrying among the CIN indication PDU; LI1~LIn indicates the length of n control information respectively.

(2) SDU of bear control information

When in step S506, sending MAC-hs PDU, MAC-hs PDU can only carry the SDU of one or more bear control information, also can carry SDU and other SDU of one or more bear control information simultaneously, wherein, other SDU are that (present Standard Edition 5 of 3GPP and version 6 is the MAC-d layer from the MAC-hs upper strata, may be rlc layer or other layers in version in the future) the MAC-hs protocol entity scheduling that needs that hands down sends to the SDU (hereinafter, being called other SDU) of UE.

Preferably, can carry at least one in the following information in the head of above-mentioned MAC-hs PDU: type identification information, whether be used to identify its corresponding SDU is the SDU of bear control information; SDU number identification information is used to identify the number of the SDU of the bear control information that MAC-hs PDU carries; SDU length mark information is used to identify the length of the SDU of its corresponding bear control information.

In addition, similar with the situation of the PDU of bear control information, the SDU of bear control information also can be carried at the identification information of above mentioning.It should be noted that above identification information is optional rather than necessary, can determine whether to carry according to need of practice.

Perhaps, can carry at least one in the following information in downlink high-speed shared control channel (HS-SCCH): whether the MAC-hs PDU of HS-SCCH frame correspondence carries the identification information of the SDU of bear control information, the number information of described SDU, the length information of described SDU.

Example 1

With reference to Fig. 7, show the example that in MAC-hs PDU, carries type identification information (SID) and number identification information (N, SDU number).

After the MAC-hs of network side handles decision-making, produce for example CQI control information (or CQI measures supplementary or the control information of MIMO pattern), do not send to rrc layer (or on physical channel, sending), but be configured to the SDU of a bear control information at the MAC-hs layer.

SID nBe used for identifying whether corresponding MAC-hs SDU (n SDU) is the SDU of bear control information.In this example, the SID of SDU correspondence that can bear control information is set to certain special value, such as complete 0 or complete 1 etc., also can be configured to the different value of SID of certain and other SDU of expression, and give UE by the RRC message informing.N represents to have the SDU of several bear control information.

Certainly, also can predesignate a PDU and be merely able to carry the SDU of a bear control information, just can not use this parameter of N this moment, but preferably, make a PDU carry the SDU of a plurality of bear control information.Similarly, can also predesignate the SDU that PDU only carries bear control information, and not carry other SDU, just can not use the SID parameter this moment.

Example 2

The scheme that provides in the example 1 mainly is at Standard Edition 5 and version 6, has provided the implementation at the MAC-hs PDU form of the following evolution of 3GPP HSPA in this example.

In the following evolution of 3GPP HSPA, the structure of its MAC-hs PDU may (do not determine as yet now, but its concrete version not influence protection scope of the present invention as shown in Figure 3.As long as adopt the mode of the SDU of MAC-hs structure bear control information that UE is controlled, all belong to protection scope of the present invention).Wherein, if certain SDU is the SDU of bear control information, then its corresponding LCH ID be exactly a special value (such as being complete 0 or complete 1, or be configured to certain value and by the RRC message informing to UE).In the following evolution of HSPA, the length of its MAC-hs SDU is variable, can indicate its length by the LI in the MAC-hsPDU head.

Example 3

Carry at MAC-hs PDU under the situation of SDU of bear control information, except representing, can also in the head of MAC-hs PDU, show the SDU (this identifier can be placed on the optional position of MAC-hs head) whether bear control information is arranged by the identifier with a fixed position by the method for special SID (version 5/6) or special LCH ID (HSPA evolution).

For example, if this identifier is 1, then show the SDU that bear control information is arranged, and the SDU of this bear control information in the end position of a SDU (or position of first SDU), and length be fix (its length can be defined as fixing any size, or by network pre-configured after, by RRC message informing UE).Correspondingly, after UE receives MAC-hs PDU, judge whether identifier is 1, if 1, then receive the SDU of the bear control information of regular length to the corresponding position, and handle accordingly according to the control information among this SDU.

Example 4

The another kind of replacement scheme of the SDU of sign bear control information is provided in this example.Its structure is shown in Figure 8.

In the filling position of MAC-hs PDU, place the SDU of bear control information.Can be in filling show SDU that whether bear control information is arranged (this identifier can be placed on the optional position of filling, and the present invention preferentially selects the 1st the bit position of filling) with the identifier of a fixed position.

For example,, show the SDU that bear control information is arranged, and the SDU of this bear control information is right after after this identifier (or occupy from last bit position of filling the SDU of this bear control information length) forward if this identifier is 1.In addition, the length of the SDU of bear control information can be fix (its length can be defined as any size, or it is pre-configured back) by RRC message informing UE by network, perhaps adopt the structure of SDU of the adjustable length bear control information of Figure 10, by the length of the SDU of the indication of the Length Indication LI value behind identifier bear control information.Correspondingly, UE is after receiving MAC-hsPDU, judged whether filling, if have, then to corresponding position, receive identifier, if identifier is 1, then after identifier, receive the SDU of bear control information according to regular length, or decoding LI, indicate the SDU that receives bear control information according to the LI value, and handle accordingly according to the control information among this SDU.

More than describe the structure of MAC-hs PDU, next, will describe the SDU of bear control information.

Example 5

The control information type The control information content Fill

Above form shows the form of the embodiment of the invention at the SDU of the bear control information of version 5 or version 6 propositions.

Wherein, " control information type " is used to show what the control information of the SDU of this bear control information is, its length can be a bit arbitrarily." control information content " can be provided with according to different control informations." filling " is optional.Because in 3GPP version 5/6, the length of MAC-hs SDU be fixed configurations (for example, the length of certain MAC-dPDU is 240bit, and the length of another MAC-d PDU is 360bit), so the length of the SDU of bear control information also should be fixed.For some control information, its length possibly can't be filled up whole SDU, so, need be with filling up.

Measuring supplementary with CQI report control information and CQI is example, in structure shown in Figure 9, supposes that SID=000000 represents that corresponding SDU is the SDU of bear control information.For example, suppose that the control information type field is that 4 bit are long, the control information type is that 0000 expression is CQI report control information, and the control information type is that 0001 expression is that CQI measures supplementary, and 0002 represents the control information of MIMO pattern.And the length of the SDU of hypothesis bear control information is 40bit.

Example 6

At the following evolution of 3GPP HSPA, provided the SDU of adjustable length bear control information, the SDU of a bear control information can carry one or more control informations.The structure of the SDU of this bear control information as shown in figure 10.

As shown in figure 10, comprise one or more control types and F identifier at the SDU of bear control information head.Wherein, control types represents control information corresponding is to belong to what type.What F represented to be right after thereafter is control types or control information.For example, if F=0, what then expression was right after thereafter is control types, if F=1, what then expression was right after thereafter is control information.Wherein, if what be right after thereafter is control information, represent that its control information corresponding is last control information among the SDU of this bear control information.
