Description

Control information sending, receiving method and device, transmission system
Technical field
The present invention relates to the communications field, particularly relate to a kind of control information sending, receiving method and device, transmission system.
Background technology
Along with informationalized high speed development, the life of people more and more be unable to do without the various services that internet provides.People wish in any place, can both obtain Internet service easily, i.e. so-called ever-online concept any time, and the preferred approach realizing this target is the packet domain carrying of wireless network.
Voice (or similar business) are when packet domain carries, because speech frame is usually very little, and speech business is all very responsive to time delay, delay variation and data error rate, so require that speech frame must be transmitted in time, and transmit again after multiple speech frame can not being connected in series.And if the transmission of each speech frame is all attended by control information, the expense of control information will very large (concrete expense ratio depends on system and realizes different) for Voice Payload.Therefore in order to improve the validity and reliability that speech business carries in packet domain, an effective method the most direct is under the prerequisite ensureing speech service quality, reduces the expense of control information as much as possible.
At present, the scheme reducing control information expense mainly contains two classes, and a class is grouping (Grouping) scheme, and another kind of is semi-persistent scheduling scheme.Introduce this two classes prior art below respectively.
Grouping (Grouping) scheme:
The core concept of this scheme is divided into groups to user, several belong to the Vo IP transmission (VoIP of same grouping, Voice over IP) user's time division multiplexing same physical layer resources, namely statistic multiplexing only carries out between the different user using same physical layer resources, and the concrete Resourse Distribute of each user then depends on layer 3 signaling and carries out preassignment; The program does not adopt adaptive coding and modulation (AMC) technology, and adopts fixed modulation/coding (MCS) scheme to carry out transfer of data; And adopt synchronous hybrid automatic repeat request (HARQ) technology and fixing redundancy version sequence.
Due to user's time division multiplexing same physical layer resources multiple in Grouping scheme, when this method is applied to high-speed slender body theory (HSDPA, High Speed Downlink Packet Access) system time, need the target receiver making an amendment to distinguish HS-DSCH to the structure (frame format) of the high speed descending sharing channel (HS-DSCH, High SpeedDownlink Shared Channel) in existing HSDPA.In addition, in advance to user grouping, need to increase extra layer 3 signaling and this grouping and pre-allocation of resources are configured.
Grouping scheme, owing to adopting the mode of fixing MCS, even if subscriber channel is very poor like this, also has no chance to change MCS, and cause data error rate large, system break probability (Outage) increases, and capacity declines; And for the situation that user channel quality improves, the MCS of this user can not be improved, the resource of this CU dynamically can not give other users, can not improve power system capacity.
Semi-persistent scheduling scheme:
In suc scheme, adopt asynchronous HARQ, the transmission first of each packet adopts fixing Resourse Distribute, retransmits the mode adopting dynamic dispatching.Namely need for each user being in active period fixes reserved resource every 20ms (continuous two speech frame time of occurrence intervals), if certain data packet transmission is made mistakes, then needing removing these is transmit first outside reserved resource to find suitable resource to retransmit, and retransmits needs and sends control information.
When semi-persistent scheduling scheme is applied to HSDPA system, also need to carry out larger change to existing HSDPA system protocol.In addition, owing to needing that resource information is first informed user in advance equally, need to increase extra layer 3 signaling and realize.
The gain that semi-persistent scheduling scheme reduces control information expense depends on re-transmission ratio, if channel is poor, retransmits ratio very high, and need dynamic dispatching owing to retransmitting, descending control overhead increases, and causes power system capacity to decline very fast.In addition, transmit fixed resource first, do not adopt AMC, to cause or error probability is large, or the situation of the wasting of resources occurs.
To sum up, there is the problem that transmission error probability is large, power system capacity can not get raising in the scheme reducing control information in prior art.

Embodiment
Due between quiet period, there is not any contact in receiving terminal and transmitting terminal, larger change may be there is in wireless channel, therefore, the first technical scheme that the control information that the embodiment of the present invention proposes sends is: after quiet period to active period conversion, when sending earlier than first data message, send control information, this activates the resource and corresponding MCS information that period, business took to inform receiving terminal, can no longer send control information before next quiet period to active period transfer point;
Consider that wireless channel has time-varying characteristics, the system change tread that should possess for channel adjusts the ability of corresponding MCS information or resource distribution mode, so the embodiment of the present invention proposes the second technical scheme that control information sends: after quiet period to active period conversion, when sending earlier than first data message, send control information, this activates the resource and corresponding MCS information that period, business took to inform receiving terminal, only had when needing to adjust corresponding MCS or resource distribution mode before next quiet period to active period transfer point, just resend new control information,
On the basis of the first technical scheme of embodiment of the present invention proposition, consider after quiet period to active period conversion, MCS may be consistent to the resource that business in previous active period takies and corresponding MCS with resource distribution mode, so in order to reduce control information further, the embodiment of the present invention propose control information send the third technical scheme: quiet period to active period change after first data packet transmission time, first judge whether to need to adjust corresponding MCS or resource distribution mode, if need adjustment, then resend the control information after adjustment, otherwise do not send control information, but send the indication information being used to indicate receiving terminal receiving data information.Can no longer send control information before next quiet period to active period transfer point.
The control information that the embodiment of the present invention proposes sends the 4th kind of technical scheme and is: after quiet period to active period conversion, when sending earlier than first data message, first judge whether to need to adjust corresponding MCS or resource distribution mode, if need adjustment, then resend the control information after adjustment, otherwise do not send control information, but send the indication information being used to indicate receiving terminal receiving data information.Had when needing adjustment MCS or resource distribution mode before next quiet period to active period transfer point, then resend the control information after adjustment, otherwise can no longer send control information.
Based on each technical scheme of the control information transmission that the invention described above embodiment proposes, accordingly all to the reception programme that should have two kinds of control informations.
The reception programme of the first control information is: receiving terminal moment Monitor and Control channel and Traffic Channel, once receive effective control information, then according to the control information of up-to-date reception on a control channel, receiving data information in the Traffic Channel of correspondence, otherwise still according to original control information, receiving data information in the Traffic Channel of correspondence.
In order to save receiving terminal (particularly for descending, user terminal is receiving terminal) energy resource consumption, the embodiment of the present invention proposes the technical scheme that another control information receives, i.e. transmitting terminal explicit notification receiving terminal, informs that quiet period arrives or informs and prepares to receive new control information.Receiving terminal receives only the data message in Traffic Channel usually, receives that transmitting terminal is explicit informs the indication information that quiet period arrives once receiving terminal, forwards control channel to monitor and the control information receiving next active period from receiving data information; Or receive the explicit indication information of informing the new control information of preparation reception of transmitting terminal once receiving terminal, also forward control channel to from receiving data information and monitor and receive new control information.After receiving terminal correctly receives control information from control channel, switch back in Traffic Channel and continue receiving data information.When receiving terminal receive transmitting terminal explicit inform prepare the indication information of receiving data information time, from monitoring on a control channel and receiving control information forwards receiving data information Traffic Channel to.
Below in conjunction with Figure of description, the specific embodiment of the present invention is described.
Fig. 1 gives the schematic diagram of the control information sending method that the embodiment of the present invention proposes.
In first active period shown in Fig. 1, the transmitting procedure of packet well describes the first technical scheme of the control information transmission that the embodiment of the present invention proposes.In first active period shown in figure, the transmission detailed process of packet is as follows:
1# packet is first packet of first active period shown in figure, when transmitting this packet, also can before first data message transmits, send control information, in order to inform the MCS and resource allocation conditions that adopt in this active period of receiving terminal, and can no longer send control information to be transformed into the transfer point of active period by quiet period at the next one before, all packets all adopt the resource identical with first packet and MCS mode.Retransmit and adopt synchronous HARQ mode, the first time of 2# packet retransmits and is occurring afterwards with transmission intercal two transmission intercals (TTI) first as shown in Figure 1, second time retransmit with transmission intercal five TTI first after occur.
In second active period shown in Fig. 1, the transmitting procedure of packet well describes the second technical scheme of the control information transmission that the embodiment of the present invention proposes.In second active period shown in figure, the transmission detailed process of packet is as follows:
7# packet is first packet of second active period shown in figure, when transmitting this packet, also can before first data message transmits, send control information, if when needing to change MCS or Resourse Distribute before the next one to be transformed into the transfer point of active period by quiet period, again send new control information, as when 8# data packet transmission, need to change MCS or Resourse Distribute, so need again to send new control information, and during 9# data packet transmission afterwards, because do not need to change MCS and Resourse Distribute, therefore no longer send control information, but adopt the MCS identical with during 8# data packet transmission and resource distribution mode.
Also by the transmitting procedure of packet in the active period of first shown in Fig. 1, the third technical scheme that the control information that the embodiment of the present invention proposes sends can be described.In first active period shown in figure, the detailed process of data packet transmission is as follows:
1# packet is first packet of diagram first active period, when transmitting this packet, also can before first data message transmits, first consistent whether with previous active period of service needed takies in this active period resource and corresponding MCS is judged, if inconsistent, then when transmitting 1# packet or before transmission 1# packet, send the corresponding control information generated according to the resource that service needed takies in this active period and corresponding MCS; If consistent, then, when transmitting 1# packet, no longer send control information, but send the indication information (this indication information does not provide in the drawings) being used to indicate receiving terminal receiving data information.
Also by the transmitting procedure of packet in the active period of second shown in Fig. 1, the 4th kind of technical scheme that the control information that the embodiment of the present invention proposes sends can be described.In second active period shown in figure, the detailed process of data packet transmission is as follows:
7# packet is first packet of diagram second active period, when transmitting this packet, also can before first data message transmits, first judge whether to need to change MCS or resource distribution mode, if needed, then when sending 7# packet or before transmission 7# packet, send the corresponding control information generated according to the resource that service needed takies in this active period and corresponding MCS; If when sending 7# packet, the control information finally sent with a upper active period is compared, do not need to change MCS or resource distribution mode, then do not send control information, but send the indication information (this indication information does not provide in the drawings) being used to indicate receiving terminal receiving data information.Afterwards in this active period, if need to change MCS or resource distribution mode, then need the new control information that again retransfers, during as 8# data packet transmission, because needs change MCS and resource distribution mode, therefore need to resend new control information, if do not need to change MCS or resource distribution mode, during as 9# data packet transmission, then no longer send control information.
These the four kinds of technical schemes illustrate that control information sends with four embodiments below, receiving, wherein illustrate that (transmission of control information and data message also can be asynchronous for the synchronous transmission of control information and data message, transmit, as long as can ensure that control information transmits earlier than data message because control information and data message are independent on control channel and Traffic Channel respectively).
Embodiment one:
In order to the first technical scheme that the control information that the embodiment of the present invention proposes sends to be described, specifically shown in Figure 2, transmitting terminal flow process is as follows:
Step 200: whether transmitting terminal detects quiet period and arrive, when detecting that quiet period arrives, sends the indication information being used to indicate quiet period and arriving;
Step 201: transmitting terminal does not detect that quiet period arrives, when being namely in active period, if need to send data, judge to need the packet of transmission to be whether first packet of active period, if it is forward step 202 to continue to perform, otherwise perform step 203;
Step 202: select rational MCS and available resources, and generate corresponding control information according to the MCS selected and available resources, and the control information of generation is sent at corresponding control channel;
Step 203: in the resource of control information instruction, and based on the MCS coded modulation service data information that control information indicates, and the service data information after coded modulation is sent;
Step 204: judge whether receive corresponding feedback information in the regulation moment, if do not had, then forwards step 205 to and continues to perform, otherwise perform step 201;
Whether step 205: when judging that last time sends packet, have sent control information, if it is forwards step 202 to and perform, otherwise perform step 201.
It should be noted that, the packet that in the embodiment of the present invention, the needs of indication send not only refers to the packet of new transmission, also comprises the packet that needs retransmit.
Receiving terminal flow process is as follows:
Step 211: Monitoring and Controlling information, and judge that whether the control information that monitors is effective, if the control information monitored is effective, then forwards step 212 to and continues to perform, otherwise returns step 211 and continue Monitoring and Controlling information.
Step 212: receiving control information also judges whether control information receives successful, if failure, returns step 211 and continues to perform, otherwise perform step 213;
Step 213: receive data service on a traffic channel according to the up-to-date control information obtained, and based on the up-to-date control information received, the work such as demodulation, decoding is carried out to the data service received, send corresponding receiving feedback information;
Step 214: judge whether to receive the indication information being used to indicate quiet period and arriving, namely judge whether to enter quiet period, if find to enter quiet period, then forwards step 211 to and continues to perform, otherwise perform step 213.
It should be noted that, the method that in the embodiment of the present invention, receiving terminal detection quiet period arrives is:
Transmitting terminal explicit notification receiving terminal, informs the arrival of quiet period.Receiving terminal only receives business information in active period on time, after the arrival receiving transmitting terminal instruction confirmation quiet period, transfers Monitor and Control information to, no longer receive and monitor business information from reception business information.After this, when receiving effective control information, after showing that active period is come again, receiving terminal starts to transfer to and receives only business information, no longer Monitor and Control information.This method does not need receiving terminal Monitor and Control information always, thus effectively can save the energy resource consumption of receiving terminal (particularly for descending, user terminal (UE) is receiving terminal).
Transmitting terminal explicit notification receiving terminal, informs that the process that its quiet period arrives is necessary.This is because: if transmitting terminal does not send quiet period instruction, then in quiet period, although transmitting terminal does not send packet to receiving terminal, receiving terminal still continues to attempt, receiving data information in the resource indicated by the control information of its up-to-date reception.And now, the data in described resource are not send to this receiving terminal, receiving terminal can be caused like this to receive the content (namely this receiving terminal correctly receives the data that other receiving terminal should receive) of mistake or unnecessary feedback in quiet period.
The method that in the embodiment of the present invention, receiving terminal detection active period arrives is:
Receiving terminal is at quiet period Monitor and Control channel.Receiving terminal once receive effective control information, or when receiving the indication information being used to indicate receiving terminal receiving data information, then shows that active period arrives, and receiving terminal goes to receive business information according to the up-to-date control information on control channel.
In addition, if the control information sent when each active period starts does not have receiving end to receive (loss) or loading error occurring (CRC check is not passed through), receiving terminal still can continue Monitor and Control information, but can not business data packet be received, also can not send and feed back to transmitting terminal.In this case, need transmitting terminal to resend control information to receiving terminal, period, the packet of loss resends by HARQ technology.In fact, because control information adopts very strong chnnel coding protection usually, the probability of makeing mistakes is very little.
It is less that the business being similar to VoIP has packet, but time delay is had to the feature of being comparatively strict with, and it adopts the gain of complete self adaptation AMC less, normally adopts fixing or only adopt a small amount of MCS scheme.But, consider that wireless channel has time-varying characteristics, the system change tread that should possess for channel adjusts the ability of corresponding MCS and resource distribution mode, the scheme embodiment of the present invention one provided is through expansion, the use of dynamic AMC and resource distribution mode can be supported, and AMC operation (Scalable AMC) that can obtain in various degree, introduces the embodiment two of the Scalable AMC mode supporting dynamic AMC and Resourse Distribute below.
Embodiment two:
In order to the second technical scheme that the control information that the embodiment of the present invention proposes sends to be described, Fig. 3 gives the transfer of data flow process of receiving terminal surveillance style, receiving terminal surveillance style requires that receiving terminal is similar to 3GPPR5 HSDPA and operates, namely receiving terminal constantly monitors the control information of its correspondence, if receive effective control information that transmitting terminal issues it, then according to new control information instruction MCS and take the reception that resource carries out business information next time, otherwise carry out business information reception according to the control information that the last time receives on a control channel.
Transmitting terminal flow process is as follows:
Step 300: whether transmitting terminal detects quiet period and arrive, when detecting that quiet period arrives, sends the indication information being used to indicate quiet period and arriving;
Step 301: transmitting terminal does not detect that quiet period arrives, when being namely in active period, if need to send data, judges that whether the packet needing to send is first packet of active period, if perform step 303, otherwise forwards step 302 to and continues execution;
Step 302: according to information such as wireless channel, data volume and loads, determines, the need of change MCS or Resourse Distribute, if needed, to select rational MCS and resource, and forward step 303 continuation execution to, otherwise, keep original MCS and Resourse Distribute, and perform step 304;
Step 303: select and resource distribution mode according to up-to-date MCS, and generate corresponding control information according to up-to-date MCS and resource distribution mode, and the control information generated is sent at the control channel of correspondence;
Step 304: based on the MCS mode coded modulation service data information of control information instruction, and the resource that the service data information after coded modulation is indicated in control information sends;
Step 305: judge whether receive corresponding feedback information in the regulation moment, if not, forwards step 306 to and continues to perform, otherwise perform step 301;
Whether step 306: when judging that last time sends packet, have sent control information, if it is performs step 303, otherwise perform step 301.
Corresponding to the second technical scheme of the control information transmission that the embodiment of the present invention proposes, the reception programme of control information has two kinds.Here illustrate for the reception programme of " receiving terminal is monitoring control channel always ", receiving terminal flow process is as follows:
Step 311: Monitoring and Controlling information, if monitor effective control information, then goes to step 312 continuation and performs, otherwise return step 311 and continue to monitor;
Step 312: receive storing control information, and judge that whether control information receives successful, continues to perform if unsuccessfully return step 311, otherwise perform step 313;
Step 313: receive data service on a traffic channel according to the up-to-date control information obtained, and based on the up-to-date control information received, the work such as demodulation, decoding is carried out to the data service received, send corresponding receiving feedback information;
Step 314: judge whether to receive the indication information being used to indicate quiet period and arriving, namely judge whether to enter quiet period, if find to enter quiet period, then forwards step 311 to and continues to perform, otherwise perform step 315;
Step 315: continue to monitor control channel, if monitor effective control information, then goes to step 312 continuation and performs, otherwise perform step 313.
Fig. 4 gives the second technical scheme that the explicit indicating mode of transmitting terminal realizes the control information transmission that the embodiment of the present invention proposes, the explicit indicating mode of transmitting terminal needs transmitting terminal to give receiving terminal explicit instruction, the sending method of indication information can have multiple, the indication information of such as 1 bit can carry out multiplexing transmission with business datum, in order to inform that receiving terminal is monitored and receives the control information on control channel, this method is without the need to receiving terminal continuous Monitor and Control information when active period, thus can receiving terminal be saved, particularly for descending, the power consumption of receiving terminal when UE is receiving terminal, and only need the overhead of increase by 1 bit, certain indication information also can send separately, when being namely ready for sending packet, judge the control information needing to change this active period, then first send separately on an indication information notice receiving terminal to control channel and receive new control information, receiving terminal can receive this packet be ready for sending in the resource of new control information instruction.The following embodiment of the present invention is carried in data message with indication information carries out multiplexingly being sent as example to illustrate.
Transmitting terminal flow process is as follows:
