Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of distribution method of ascending resource, and the transmitting terminal device of the receiving end device of upstream data and upstream data.
Background technology
Mobile communication system is one of focus of present Research on Communication Technology.Along with the evolution and the development of mobile communication technology, broadband and IP packet switch is main development trend.In the research of present 3G, 3.5G and 4G, realize that the spectrum efficiency of higher throughput and Geng Gao has become one of research emphasis.
Realize that higher throughput and the spectrum efficiency of Geng Gao have number of ways, comprise the introducing and the realization of various diversity techniques, a kind of approach wherein is exactly more effectively to improve the effective bandwidth that is used for transfer of data in the communication bandwidth.In mobile communication system, carry various control signalings by control channel usually, come the bearer service transfer of data by data channel.So, how to design a communication system efficiently, under the prerequisite of the normal effectively running of assurance system, reduce the expense of control channel as far as possible, thereby improving the occupation proportion of Traffic Channel, improve the throughput of whole system, is an important research project all the time.In the design of control channel, being carried as descending and assignment message ascending resource of user's assignment is one of main effect of control channel.
In the mobile communication system of the packet switch that present commercial and industry is being studied, because each user has sudden, distributed characteristics in descending or up request of data, so need carry out respectively according to the service request of user's downlink or uplink at each user's resource allocation.Specifically, be exactly in the design of control channel, when network side has data to send to the user, by network side is user terminal allocation of downlink channel resource, and by sending down channel assignment message informing user terminal, user terminal just takies reception and the processing that corresponding resource is carried out downlink data according to this message; When the user has data to send to network side, by network side is that user terminal distributes uplink channel resources, and by sending up channel assignment message informing user terminal, user terminal takies preparation and the transmission that corresponding resource is carried out upstream data according to this message.
In ofdm system, be divided into lasting assignment (Persistent Assign) and non-ly continue two kinds of (non-Persistent Assign) assignments according to resource allocation change situation in time.Wherein non-lasting assignment is meant that current assignment is only effective to current data packets for transmission, and packet is successfully decoded or the HARQ retransmission processes finishes then that assignment ceases to be in force automatically, and sets the assignment cycle and carry out assignment again; Lasting assignment is meant that beginning information such as the resource of institute's assignment and transformat from successful assignment no longer changes, and disconnects or goes assignment (de-assign) or carry out assignment again until link, and this lasting assignment was just lost efficacy.Adopt to continue the assignment mode can save/expense of descending assignment message, especially for VoIP (Voice over IP, IP-based audio call) business, because its bag is long smaller, if bag of every transmission all sends an assignment message, then cause a large amount of assignment messages in network, to transmit, therefore increased the expense of system greatly.And adopt to continue the assignment mode, sends assignment message after, the resource long-term of distributing to this user is effective, till assignment message is removed in the network side transmission.
In the prior art, after network side sends and continues assignment message, user terminal is by the resource of assignment, according to the voice packet behind the set point number transmission coding, network side can be responded an acknowledge message to user terminal after demodulating the packet of transmission, and whether this packet of informing user terminal correctly receives.Carry a sign in this acknowledge message, this sign has 3 values, whether is correctly decoded the data that receive in order to show network side, and shows at this user's lasting assignment whether also remain valid.When the value of this sign is+1, show that network side is correctly decoded data, the lasting assignment of this time is still effective, and user terminal can continue to use the resource that continues assignment to send data; When the value of this sign is 1, show that network side is correctly decoded data, but the lasting assignment of this time is no longer valid from send next time, user terminal can not re-use the resource that continues assignment and send data, promptly is equivalent to go assignment at this user terminal; When the value of this sign is 0, show that network side fails correctly to demodulate the speech coding bag content of transmission, need the user terminal data retransmission.User terminal receives and carries ident value for after+1 or-1 the affirmation message, need not continue to send the information of this bag; User terminal receives and carries ident value is after 0 the affirmation message, and retransmission data packet may is carried ident value for till+1 or-1 the affirmation message up to what receive that network side returns; If user terminal never receives the affirmation message of network side, then user terminal can continue to send packet till the maximum retransmission.
Prior art is for the terminal of non-lasting assignment, and network side also can be responded an acknowledge message to user terminal after demodulating the packet of transmission, and whether this packet of informing user terminal correctly receives.Carry a sign in this acknowledge message, this sign has 2 values.When the value of this sign is+1, show that network side is correctly decoded data, this time assignment was lost efficacy; When the value of this sign is 0, show that network side fails correctly to demodulate the speech coding bag content of transmission, need the user terminal data retransmission, carry ident value for till+1 the affirmation message up to what receive that network side returns; If user terminal never receives the affirmation message of network side, then user terminal can continue to send packet till the maximum retransmission.
The voip user is being carried out in the process of resource assignation, network side need distribute the quantity of the subcarrier of this user's use for the user.Generally speaking, the quantity of distributing to user's subcarrier can not be very little, otherwise can increase the expense of assignment message.In resource allocating message, NodeID is used to identify the subcarrier of distributing to the user corresponding to the combination of a series of subcarrier.In once continuing assignment process, voip user fixedly takies the resource of a NodeID correspondence at this section some time slot in the time.Because at present the VoIP speech coding technology strengthens day by day, the flow that needs interface aloft to send reduces day by day, thereby a voip user takies resource at this section period internal fixation and caused bigger redundancy.
Referring to Fig. 1, send the schematic diagram of upstream data for the terminal that continues assignment in the prior art.As shown in Figure 1, general VoIP assignment is carried out at one or more interlace.Suppose that the interlace number is 6, then the 1st among Fig. 1,7,13,19...... frame belong to an interlace.Suppose that in the time interval that 2 VoPs send, each has send opportunity four times by the terminal that continues assignment.But under a lot of situations, after by transmission once or twice, the base station of network side just can receive data, does not need to take the resource of all the lasting assignments in the 20ms.For example, after the base station correctly received the data of user1 by the 1st frame and the 7th frame, the 13rd frame and the 19th frame that belong to user1 just became idle frame, under this kind situation, will cause the waste of resource for ofdm system.
In order to address the above problem, prior art adopts Poewr control method to reach the purpose of saving resource, promptly send user's VoIP packet with lower power, thereby needing more time resource to finish data sends, to fill up the redundancy of the subcarrier of distributing to the voip user, and remaining power division is given the user of other non-sticky assignments, thus the throughput of elevator system.
Although the redundancy that the NodeID that above-mentioned prior art has adopted power control mechanism to fill up the minimum of distributing to the voip user is available, but because terminal channel is relatively good under some situation, can fulfil data ahead of schedule with less power fully sends, therefore, said method will cause the waste of power resource.When voip user's number of service was on the increase simultaneously in the system, because the waste of power resource, total number of users of system's support also was subjected to certain restriction.Thereby influenced the throughput of whole system.

Embodiment
Among the present invention, the idling-resource that the base station will obtain being discharged in the terminal transmission upstream data process of persistent resources assignment is temporarily distributed to other-end and is used, and regain the resource of its lasting assignment under certain condition, thereby improved the availability of frequency spectrum of system, and increased power system capacity.
Describe the present invention below by two embodiment.
Embodiment one
Present embodiment is described in the VoIP system, and after the resource allocation that the base station will obtain continuing the terminal of assignment was used to other-end, this obtained continuing the indication of the terminal of assignment according to network side, regains the process of the resource of its lasting assignment.
Referring to Fig. 2, the terminal that obtains lasting assignment for the present invention regains the schematic flow sheet of its lasting assigned resources according to the network side indication.Suppose that each terminal that continues assignment by network side has four secondary data send opportunity in two data send at interval, the concrete steps of its resource assignation comprise:
1, the base station is distributed ascending resource according to the service request of user1 for it, and is assigned as the resource of its distribution by continuing the assignment mode to it.
When user1 has upstream data to send, initiate request to the base station.After request is received in the base station,, and send lasting assignment message, the assignment information of carrying ascending resource for user1 distributes ascending resource.User1 distributes to its lasting assigned resources by resolving this assignment message acquisition.In the present embodiment, the 1st frame to the 22 frames shown in Figure 2 are the transmission interval of two VoIP packets; 1st, 7,13,19,25 frames ... belong to an interlace are for distributing to the ascending resource of user1.
2, user1 sends cycle (the 1st frame shown in Fig. 2) transmission upstream data in the first time of the interlace at its place, and according to data transmission situation, in the packet that sends, carry a sign, can temporarily use by other-end in order to the lasting assigned resources that shows this terminal.
Usually, carrying a sign in the MAC packet header of terminal last packet to be sent in buffering area, is last packet that present terminal need send in order to show this bag.
3, at first feedback cycle of the interlace at user1 place, the base station sends NACK message to user1, and the value of carrying is 0 sign, shows that it fails to be correctly decoded the upstream data of user1 transmission.
4, after user1 receives NACK message, judge that ident value is 0, then send the data that the cycle (the 7th frame shown in Fig. 2) retransmits the base station decodes failure second time in the interlace at its place, comprise the sign that temporary transient permission other-end uses its resource in the packet of this re-transmission.
5, after the base station was correctly decoded the data of user1, decision was temporarily distributed to user2 with the lasting assigned resources of user1 and is used, and notice user1 temporarily stops using the resource of its lasting assignment.
The base station receives data that user1 sends and successfully after the decoding, at first judge wherein whether to comprise and show that it allows other-end to use the sign of its resource, if comprise, then the base station also will be according to the number of users of current service, and whether decision distributes to other-end with the lasting assigned resources of user1 is used.If the user of current wait service is more, then the lasting assigned resources of user1 can be distributed to user's use to be served in the base station, so that improve the capacity of system.
Whether the base station correctly receives data and indicates it whether temporarily to stop using the resource that continues assignment by ACK acknowledge message notice user1.If the base station is correctly decoded data and decision is not used the resource allocation of user1 to other-end, then with show in the acknowledge message sign that whether correctly receives data be changed to+1, user1 receives and will continue use after this message and be the resource of its lasting assignment; If the base station is correctly decoded data and the lasting assigned resources of user1 is distributed to other-end use, then above-mentioned sign is changed to-1.
After the base station was correctly decoded the data of user1 transmission in the present embodiment, the user2 that decision is distributed to the service of wait with the lasting assigned resources of user1 used.So the base station is distributed to user2 by the mode of non-lasting assignment with the lasting assigned resources of user1; Simultaneously second feedback cycle at the interlace at user1 place returns ACK message to user1, and will be changed to-1 in order to what show the sign that whether correctly receives data.
6, after user1 receives the ACK message of base station transmission, temporarily stop using the resource of its lasting assignment; In the cycle of transmission for the third time (the 13rd frame shown in Fig. 2) of the interlace at user1 place, user2 uses the lasting assigned resources of user1 to send data.
What user1 judged showing of carrying in the ACK message whether the base station correctly receive data is designated-1, at this moment, whether user1 judges to comprise in its last packet that sends and shows the sign that allows other-end to use its lasting assigned resources, if comprise, then continue to keep the resource of this lasting assignment effective, but from temporarily stop using this resource this moment; If do not comprise, then stop using resource, and this resource lost efficacy to the assignment of user1 into its lasting assignment.
7, after the base station is correctly decoded the data of user2 transmission, according to current system situation decision the lasting assigned resources of user1 is distributed to userN and use.
The 3rd feedback cycle at the interlace at user1 place, ACK message is returned to user2 in the base station, and sign is changed to+1, show and be correctly decoded the data that user2 sends, send non-lasting assignment message to the userN that waits for service then, the lasting assigned resources assignment of user1 is used to userN.
ACK message is broadcasted by broadcast mode in the base station on shared control channel, any terminal can both listen to.After user1 listens to this ACK message, find that ident value is+1, judge in view of the above that then the resource of its lasting assignment is still used by other-end, this moment, user1 was left intact; After user2 monitors this ACK message, find that ident value is+1, judge in view of the above that then the base station has correctly received the data of its transmission, stop using the resource of assignment this moment.
8, in the 4th the transmission cycle (the 19th frame shown in Figure 2) of the interlace at user1 place, userN uses the lasting assigned resources of user1 to send data.
9, the base station sends acknowledge message to userN, and indication user1 regains the resource of its lasting assignment.
Have data will send a request message before will uploading owing to continue the terminal of assignment, so the base station can send the request of data according to user1, the resources use right of user1 is returned in decision.
Receive the data sending request of user1 when the base station after, after the data that the correct terminal that receives the resource of current use user1 sends, return ACK message to it, and ident value is changed to-1, show to be correctly decoded data, and indication user1 regains the resource that continues assignment.
Take the resource data retransmission of user1 for a certain reason for a long time for fear of the terminal of non-lasting assignment, influence the transfer of data of user1, its maximum retransmission can be limited in the base station when it being carried out non-lasting assignment.
In the present embodiment, at the 4th feedback cycle of the interlace at user1 place, ACK message is returned to userN in the base station, and sign is changed to-1.
Among the present invention, the sign of base station in the ACK message of feeding back to the terminal of non-lasting assignment is set to-1, shows that the base station is correctly decoded data, and simultaneously, the terminal that also plays the lasting assignment of indication regains the effect of the resource that continues assignment.
10, the user1 resource concurrence that regains its lasting assignment send data.
After userN listens to the ACK message of base station transmission, find that ident value is-1, judge that in view of the above the base station has correctly received the data of its transmission, stop using this moment the resource of assignment to send data; After user1 monitors this ACK message, find that ident value is-1, user1 judged in its last packet that sends and comprised the sign that allows other-end temporarily to use its assigned resources this moment, then regained the resource of its assignment, recovered to send data on the interlace at its place.
Embodiment two
Present embodiment is described in the VoIP system, after the resource allocation that the base station will obtain continuing the terminal of assignment is used to other-end, regains the process of the resource of its lasting assignment when setting-up time arrives.
Referring to Fig. 3, the terminal that obtains lasting assignment for the present invention regains the schematic flow sheet of the resource that continues assignment automatically after setting-up time arrives.Suppose that each terminal that continues assignment by network side has four secondary data send opportunity in two data send at interval, the concrete steps of its resource assignation comprise:
1, the base station is distributed ascending resource according to the service request of user1 for it, and is assigned as the resource of its distribution by continuing the assignment mode to it.
The base station needs to carry a time value in continuing assignment message, with the time that the terminal of indicating lasting assignment can allow other users to use its resource, that is, the terminal that continues assignment when this time arrives will regain its resource.Because sending at interval, data have uncertainty, long if the time of this agreement is compared with real data transmission interval, and then can influence the user who continues assignment and send data; If too short, then do not reach the purpose that idling-resource is made full use of, therefore, need send the interval to the data of terminal and be provided with.Can be by the time interval of agreement in agreement to the terminal transmission upstream data of lasting assignment, when terminal was continued assignment, by a system parameters, indicating terminal was uploaded the time interval of data.
The time value that the base station is set for the terminal that continues assignment can send interlude length for one or more data.
2, user1 sends the cycle (the 1st frame shown in Fig. 3) first time in the interlace at its place and sends upstream data, and according to data transmission situation, in the packet that sends, carry a sign, can temporarily use by other-end in order to the lasting assigned resources that shows this terminal.
3, at first feedback cycle of the interlace at user1 place, the base station sends NACK message to user1, and the value of carrying is 0 sign, shows that it fails to be correctly decoded the upstream data of user1 transmission.
4, after user1 receives NACK message, judge that ident value is 0, then send the data that the cycle (the 7th frame shown in Fig. 3) retransmits the base station decodes failure, comprise the sign that temporary transient permission other-end uses its resource in the packet of this re-transmission in the second time of the interlace at its place.
5, after the base station was correctly decoded the data of user1, the user2 that decision is temporarily distributed to the service of wait with the lasting assigned resources of user1 used.
The base station is distributed to user2 by the mode of non-lasting assignment with the lasting assigned resources of user1; Simultaneously second feedback cycle at the interlace at user1 place returns ACK message to user1, will be changed to-1 in order to what show the sign that whether correctly receives data.
After guaranteeing designated time arrival, when user1 uses the resource that regains to carry out transfer of data, there are not other users to send data on this resource, the maximum retransmission that the user of non-lasting assignment can be specified according to current available resource quantity in the base station, in order to avoid the user of this non-lasting assignment takies this resource data retransmission for a long time for a certain reason, so that the user of this non-lasting assignment when the designated time arrives does not also discharge resource, and clashes with user1.
For example in the present embodiment, the base station judges that the time slot that also has 2 free time at present can distribute user2 to use, and then when being the user2 assigned resources, restriction user2 maximum retransmission is 2, no matter make user2 base station feeding back ACK message whether after maximum retransmit 2 times, all stop to send data.
6, after user1 receives the ACK message of base station transmission, judge that the ident value that whether correctly receives data that shows that wherein carries is-1, and judge to comprise in the own last packet that sends and show the sign that allows other-end to use its lasting assigned resources, then user1 continue to keep this lasting assignment resource effectively but temporarily stop using this resource.
After user2 received assignment message, the cycle of transmission for the third time in the interlace at user1 place (the 13rd frame shown in Fig. 3) sent data.
7, at the 3rd feedback cycle of the interlace at user1 place, ACK message is returned to user2 in the base station, and sign is changed to+1, show and be correctly decoded the data that user2 sends, send non-lasting assignment message to the userN that waits for service then, the lasting assigned resources assignment of user1 is used to userN.
The base station judges that the time slot that also has 1 free time at present can distribute userN to use, and then when being the userN assigned resources, restriction userN maximum retransmission is 1.
8, in the 4th the transmission cycle (the 19th frame shown in Figure 3) of the interlace at user1 place, userN uses the resource of assignment to send data.
9, at the 4th feedback cycle of the interlace at user1 place, ACK message is returned to userN in the base station, and sign is changed to+1, show to be correctly decoded the data that userN sends.
10, after the designated time arrival, the resource concurrence that user1 regains its lasting assignment send data.
