Abstract
Techniques for efficiently assigning resources for spurts of traffic in a wireless communication system are described. The system may support semi-persistent and non-persistent resource assignments. A semi-persistent resource assignment is valid for as long as more data is sent within a predetermined time period of last sent data and expires if no data is sent within the predetermined time period. A non-persistent resource assignment is valid for a predetermined duration or a specific transmission. A semi-persistent resource assignment may be granted for an expected spurt of data to send via the communication link. For Voice-over-Internet Protocol (VoIP), a semi-persistent resource assignment may be granted for a voice frame in anticipation of a spurt of voice activity, and a non-persistent resource assignment may be granted for a silence descriptor (SID) frame during a period of silence.

Fig. 1 shows the wireless multiple-access communication system according to a kind of design.The Node B of evolution (eNB) 100 comprises a plurality of antenna sets, and one group comprises antenna 104 and 106, and another group comprises antenna 108 and 110, also has one group and comprises antenna 112 and 114.In Fig. 1, every group of antenna only shows two antennas.But every group of antenna also can use more or less antenna.Typically, eNB is the fixed radio station for communicating by letter with UE, also can be called Node B, base station, access point etc.
UE 116 communicates by letter with 114 with antenna 112, and wherein, antenna 112 and 114 passes through down link 120 to UE 116 transmission information, and passes through up link 118 from UE 116 reception information.UE122 communicates by letter with 108 with antenna 106, and wherein, antenna 106 and 108 passes through down link 126 to UE 122 transmission information, and passes through up link 124 from UE 122 reception information.Typically, UE can be that fix or mobile, also can be called mobile radio station, terminal, accesses terminal, subscriber unit, radio station etc.UE can be mobile phone, personal digital assistant (PDA), Wireless Telecom Equipment, handheld device, radio modem, kneetop computer etc.In Frequency Division Duplexing (FDD) (FDD) system, communication link 118,120,124 and 126 can be used different frequencies to communicate.Give an example, down link 120 and 126 can be used a frequency, and up link 118 and 124 can be used another frequency.
That whole overlay areas of eNB 100 can be divided into is a plurality of (such as, three) little zone.Not antenna on the same group by eNB 100 is these zonules services.In 3GPP, term " community " refer to eNB minimum overlay area and/or be the eNB subsystem of this overlay area service.In other systems, term " sector " refers to minimum overlay area and/or is the subsystem of this overlay area service.For the sake of clarity, adopt in the following description the 3GPP concept of community.In a kind of design, three groups of antennas of eNB 100 are supported the communication of the UE in eNB 100 San Ge communities.
Fig. 2 shows the design block diagram of eNB 100 and UE 116.In this design, eNB100 is equipped with T the antenna of 224a to 224t, and UE 116 is equipped with R the antenna of 252a to 252r, common T >=1, R >=1.
At eNB 100, emission (TX) data processor 214 receives the business datum of one or more UE from data source 212.TX data processor 214 is according to being the selected one or more encoding schemes of each UE, to the business datum of this UE processed (such as, format, encode and interweave) in order to obtain coded data.Then, TX data processor 214 according to be the selected one or more modulation schemes of each UE (such as, BPSK, QSPK, M-PSK or M-QAM), the coded data of this UE is modulated to (or sign map), in order to obtain modulation symbol.
TX MIMO processor 220 can adopt any multiplexing scheme, by the modulation symbol of frequency pilot sign and all UE, is undertaken multiplexing.The given data that pilot tone is normally processed according to known way, and can be by receiver for channel estimating and other purpose.220 processing of TX MIMO processor (such as, precoding) multiplexing modulation symbol and frequency pilot sign, and T output symbol stream is provided to T transmitter (TMTR) 222a to 222t.In some design, 220 pairs of modulation symbols of TX MIMO processor carry out the beam forming weighting in order to these symbols are carried out to steric direction.Each transmitter 222 is processed output symbol stream separately, such as, for OFDM (OFDM), in order to obtain the output code laminar flow.Each transmitter 222 also process (such as, be converted to simulation, amplification, filtering and up-conversion) the output code laminar flow to be to obtain down link signal.Launch respectively T the down link signal to 222t from transmitter 222a by T antenna 224a to 224t.
At UE 116, antenna 252a is 100 receiving downlink signals to 252r from eNB, and provide the reception signal to receiver (RCVR) 254a to 254r respectively.254 pairs of reception signals separately of each receiver regulated (such as, filtering, amplification, down-conversion and digitlization) in order to obtain sampling, and further process these sampling (such as, for OFDM) in order to obtain receiving symbol.MIMO detector 260 is according to MIMO receiver treatment technology, to from 254a, to the reception signal of the whole R of a 254r receiver, being received and processed, in order to obtain symbol after testing, and the estimation of the modulation symbol of namely eNB 100 emissions.Then, receive (RX) data processor 262 process (such as, rectification, deinterleaving and decoding) the symbol after testing decoded data of UE 116 is provided to data sink 264.Typically, MIMO detector 260 and the performed processing of RX data processor 262 are the complementary operations of the performed processing of the TX MIMO processor 220 of eNB 100 and TX data processor 214.
On up link, at UE 116, process, by modulator 280, further process, regulated to 254r by antenna 254a by TX data processor 278 from business datum and the signaling message of data source 276, and be transmitted into eNB 100.At eNB 100, from the uplink signal of UE 116 by antenna 224 receive, by receiver 222 regulate, by demodulator 240 demodulation, and processed by RX data processor 242, in order to obtain business datum and the message of UE 116 emissions.
Controller/processor 230 and 270 is managed respectively the operation of carrying out at eNB 100 and UE 116.Memory 232 and 272 is stored respectively data and the program code of eNB 100 and UE 116.Scheduler 234 is UE schedule downlink and/or ul transmissions, and distributes for the UE of its scheduling provides resource.
This system is supported mixed automatic retransfer (HARQ) in order to improve the reliability of transfer of data.For HARQ, transmitter sends the transmission of Frame, and if if required, sends one or more re-transmissions, until receiver is correctly decoded this Frame, or sent the re-transmission of maximum quantity, or till running into some other termination situations.Frame also can be called grouping, data cell, data block etc.
Fig. 3 shows in LTE and adopts HARQ to carry out the example of transfer of data on up link.UE116 has data to send on up link, so transmit request, the uplink resource on request Physical Uplink Control Channel (PUCCH).ENB 100 receives this resource request from UE 116, and returns to the allowance of uplink resource on Physical Downlink Control Channel (PDCCH).UE 116 process frames of data A, and above transmit this frame with the capable physically shared channel (PUSCH) of the reverse link resources of permitting.The frame transmission occupies a subframe, and this subframe is 2 milliseconds (ms) in LTE, but can be also other duration, such as 1ms, 5ms, 10ms etc.Subframe can also be called Transmission Time Interval (TTI).The transmission of eNB 100 received frame A, make a mistake when frame A is decoded, so just in the upper Negative Acknowledgement (NAK) that sends of acknowledgement channel (ACKCH).UE 116 receives these NAK new transmission frame A that lays equal stress on.The re-transmission of eNB 100 received frame A, be correctly decoded frame A according to initial transmission and re-transmission, then sends and confirm (ACK).UE 116 receives this ACK, then in the mode that is similar to frame A, processes and transmit next Frame B.
Each transmission and each re-transmission of Frame all can be described as the HARQ transmission.The HARQ the number of transmissions of Frame depends on received signal quality of modulation that this Frame is used and encoding scheme (MCS), this Frame etc.MCS can also refer to speed, frame format, packet format, transformat etc.Select MCS for Frame and stop with the HARQ of realize target, namely Frame is correctly decoded the desired amt of required HARQ transmission.The HARQ of target stops longer, and the level of resources utilization is just higher, but the cost of paying be postpone also just longer.
Define Q HARQ example or interweave, wherein Q can be any integer value.Each HARQ example comprises by Q the separated subframe of subframe.Gives an example, define six HARQ examples, and HARQ example q comprises subframe q, q+6, q+12 etc., wherein q ∈ 0 ..., 5}.
HARQ processes all transmission and the re-transmission (retransmitting if exist) that relates to Frame.HARQ processes when resource is available, after transmission for the first time or one or many re-transmission, stops.The duration that HARQ processes is variable, and it depends on the decoded result at receiver.Each HARQ processes and sends on a HARQ example, and on Q HARQ example, parallel Q the HARQ altogether that send processes.
Once UE 116 has business datum to send on up link, this UE just sends uplink resource request.ENB 100 returns to the allowance of uplink resource to UE 116.UE 116 receives the business datum burst that will send on up link.These bursts can start at any time and can continue any time.Give an example, UE 116 has voip call and receives the burst of speech data from chat user.VoIP be applied between the burst period of speech activity with a certain speed (such as, every 10ms or 20ms) speech frame is provided, and provide the SID frame with another speed (such as, every 160ms) between silence period.UE 116 can't know when can receive the Frame that will transmit in up link from the VoIP application in advance.Once from VoIP application receive Frame (such as, speech frame or SID frame), UE 116 just sends the request of uplink resources to eNB 100, from the allowance of eNB 100 receiving uplink resources, with the resource transmission Frame of permitting.But the request on the up link of each Frame and the transmission of the allowance on down link, can cause high control channel expense.
In one aspect, system supports dissimilar resource to distribute, than as shown in table 1.
Table 1
| distribute type | describe |
| the persistence resource is distributed | in indefinite time span, effective resource is till countermanded distributed. |
| semi-persistent resource allocation | need only in the predetermined amount of time of the data that in the end send and also have data just to send effectively, and if while there is no the data transmission in this predetermined amount of time, the resource with regard to automatic stop is distributed. |
| the perishability resource is distributed | at predetermined lasting time or for the effective resource of specific transmission, distribute. |
Typically, resource can use frequency (such as, one group of subcarrier), time (such as, symbol period or subframe), code, transmitting power etc., or their any combination is quantized.The resource of permitting in semi-persistent resource allocation is called pre-configured resource, predefine resource, pre-allocation resource etc.Predetermined amount of time is also referred to as overtime period.
Semi-persistent and perishability resource are distributed can effectively be applied to any application that data burst is arranged.For VoIP, the speech frame of semi-persistent resource allocation for sending between the speech activity burst period, and the perishability resource is divided and is used in the SID frame sent between silence period.Semi-persistent resource allocation provides superperformance and reduces the control channel expense for voice bursts.Owing to there being the long time interval between the SID frame, so the perishability resource distributes and to be applicable to the SID frame, and because the arrival of SID frame is not frequent, so the control channel expense is rational.
Once UE 116, have data to send on up link, this UE just sends the request of uplink resource on PUCCH.UE 116 indicates amount and/or the type that will send data in resource request.For VoIP, in resource request, whether indication UE 116 has the size of speech frame or SID frame, speech frame or data rate etc.Typically, to different data buffering grades or frame rate (such as, full-rate vocoding, half rate frame, 1/4th rate frame, SID frame etc.), different frame type (such as, header VoIP frame and the incompressible header VoIP frame of compression) and/or point out the amount of the data that will send and/or the out of Memory of type, adopt different code words.UE 116 selects suitable code word according to its data buffering grade, and is sent as the code word that resource request is selected.In a kind of design, VoIP is adopted to two kinds of code words---a kind of for the full-speed voice frame, another kind of for the SID frame.
ENB 100 receives resource request from UE 116, and distributes suitable resource according to this request.In a kind of design, eNB 100:(i) for the resource request of speech frame, permit semi-persistent resource allocation; Or, (ii) for the resource request of SID frame, permit the perishability resource and distribute.In a kind of design, if support the multiple voice frame rate, semi-persistent resource allocation is for the highest supported speech frame rates, such as, full rate.This design makes the enough semi-persistent resource allocation of UE 116 energy send speech frame with the speed of any support.In another kind design, this semi-persistent resource allocation is for the most frequently used speech frame rates, the speech frame rates of asking, etc.
UE 116 receives the perishability resource from eNB 100 and distributes, and uses permitted uplink resource in one period predetermined duration, and this time is enough transmitted a SID frame.UE 116 after this predetermined lasting time (such as, after sending this SID frame) abandon permitted uplink resource.
UE 116 receives semi-persistent resource allocation from eNB 100, and also has data to launch as long as UE is interim when this is overtime, just keeps the uplink resource of permitting.The length in overtime period can be value that fix or configurable, and selects the time interval of expecting between the continuous data frame that namely UE116 will send according to the frame interval time of advent.For VoIP, the every 10ms of UE 116 or 20ms send speech frame, and be that 40ms is to 80ms overtime period.UE 116 is used timer to carrying out timing overtime period.UE 116 is using permitted uplink resource to start timer after sending first speech frame, as long as and sent the subsequent voice frame and just restart timer.When timer expiry, UE 116 abandons the uplink resource of permitting, and is launched without these resources.
If the uplink resource of permitting stops naturally owing to not using overtime period always, determine the time quantum that does not use the uplink resource of allowance in the data burst ending this overtime period.In order efficiently to utilize available resources, if UE 116 does not wish to re-use the uplink resource of allowance, UE 116 can send signaling in order to abandon the uplink resource of this allowance before stopping overtime period.In a kind of design, UE 116 sends the request of not indicating with data, as the in-band signalling in the final data frame of current data burst expectation.In another kind design, if UE 116 phase transmitting data at one's leisure not, UE 116 send not request with the data indication (such as, on PUCCH).Be longer than the frame interval time of advent this idle period, but be shorter than overtime period.Give an example, if every 10ms or 20ms send speech frame, be the 30ms left and right idle period, namely is longer than two time intervals between speech frame to allow there is shake in speech frame arrival.UE 116, after the Frame from last emission starts through idle period, sends the request of not indicating with data.If adopt HARQ, permitted the uplink resource about one or more HARQ examples to UE 116.The HARQ example that UE 116 is each distribution sends the independent request of not indicating with data.As another kind, select, UE 116 can send for the HARQ example of all distribution an independent request of not indicating with data.In any case, the quick releasing that the request support resource of not indicating with data distributes, and accelerate the resource allocation between UE.In order to reduce the transmission time, can use lower modulation and code power grade and/or higher emitting power grade, send the request of not indicating with data.
Typically, semi-persistent resource allocation stops according to following any point:
Interim when overtime do not have data to send,
UE sends explicit signaling and distributes to stop resource,
ENB sends and shows that signaling is to stop the resource distribution,
Resource is redistributed to another UE.
Fig. 4 shows the example of the VoIP transmission distributed by semi-persistent and perishability resource.In time T
11, UE 116 has speech data to send on up link, and sends request, and is full-rate vocoding request uplink resource.In time T
12, eNB 100 has the semi-persistent resource allocation of enough uplink resources for full-rate vocoding returns.In time T
13, the uplink resource that UE 116 use are permitted is launched first speech frame.UE 116 is in time T
14, T

16the interim speech frame of not launching during afterwards overtime.In time T
17, time T namely
16in overtime period afterwards, semi-persistent resource allocation stops, and UE 116 abandons the uplink resource of permitting.
In time T
21, UE 116 has the SID frame to send on up link, and is that this SID frame transmits uplink resource request.In time T
22, the perishability resource that eNB 100 has enough uplink resources for the SID frame returns is distributed.In time T
23, the uplink resource that UE 116 use are permitted transmits the SID frame.After transmission SID frame, the perishability resource is distributed termination, and UE 116 abandons the uplink resource of permitting.
In time T
31, UE 116 has speech data to send on up link, and sends request, and is full-rate vocoding request uplink resource.In time T
32, eNB 100 has the semi-persistent resource allocation of enough uplink resources for full-rate vocoding returns.UE 116 is in time T
33transmit first speech frame with the uplink resource of permitting, and in time T
34transmit extra speech frame.In time T
34t in idle period afterwards
idlein do not launch speech frame.In time T
35, time T namely
34in idle period afterwards, UE 116 transmits the request of not indicating with data, in order to abandon the uplink resource of permitting.
The semi-persistent resource allocation indication is for sending the specific resources of data.The particular resource block of resource in specific sub-frame of permitting provides.Each Resource Block covers in the specific duration one group of subcarrier of (such as a, subframe).If adopt HARQ, the uplink resource of permitting is for one or more specific HARQ examples.Semi-persistent resource allocation is also indicated one or more for sending the specific MCS of data.Each MCS is associated with particular frame size, specific coding scheme or bit rate, certain modulation schemes etc.No matter when, eNB 100 and UE 116 know resource and the MCS for sending data.
In a kind of design, the uplink resource that UE 116 use are permitted sends data on up link, and will send data without sending any signal notice eNB 100.In this design, the transmission in each subframe that eNB 100 attempts it is received on permitted uplink resource is decoded, and UE 116 may send data in each subframe.100 couples of UE 116 of eNB carry out blind decoding for each MCS that sends data.In the another kind design, the Frame that UE 116 notice eNB 100 are sending, and may also notify eNB to be used for the MCS of this Frame.In this design, 100 of eNB when being notified, the transmission attempt decoding further according to MCS (if transmission), it received.For these two kinds of designs, if eNB 100 is interim when overtime, the Frame from UE 116 is not correctly decoded, eNB 100 removes the distribution of uplink resource.If adopted HARQ, eNB 100 waits for the time slightly longer than overtime period, in order to took into account possible ACK/NAK mistake before the distribution of removing the uplink resource of permitting.
Typically, use semi-persistent and perishability resource divide timing can adopt HARQ or do not adopt HARQ.If adopt HARQ, semi-persistent and the distribution of perishability resource are defined as to some aspect that contains HARQ.In a kind of design, semi-persistent or perishability resource are distributed all transmission and the re-transmission of containing Frame.In the another kind design, the transmission for the first time of Frame is only contained in semi-persistent or the distribution of perishability resource, and later retransmission is dispatched to another distribution.For semi-persistent resource allocation, HARQ stops statistic and should complete in the frame interval time of advent on an average.Give an example, if every 20ms sends Frame, the average magnitude of the HARQ of each Frame transmission should be less than 20ms, to prevent that data stacking is in data buffer.For only containing the resource that Frame transmits for the first time, distribute, HARQ stops statistic can be longer than HARQ transmission (such as, 1.2HARQ transmission) a little, in order to be reduced to the quantity of the resource request that Frame retransmits.
Select quantity and/or the target HARQ of HARQ example to stop, to reach efficient resource utilization.Can distribute according to interval, resource between the frame interval time of advent, continuous HARQ transmission is only to contain transmit for the first time or contain all HARQ transmission etc., comes select target HARQ to stop.The MCS that selection will transmit and code bit, so that can realize maximum coding gain for the par of HARQ transmission, the par of this HARQ transmission is stopped determining by target HARQ.The data volume that can send in a HARQ example depends on that target HARQ stops (stop sending more data for longer HARQ, vice versa) and other factors.The quantity of HARQ example is configurable, and selects according to the total amount that sends data, the data volume sent on each HARQ example etc.
Typically, semi-persistent and perishability resource are distributed can be for the transfer of data on up link (as mentioned above), also can be for the transfer of data on down link.For down link, when eNB 100 has data to send to UE 116, eNB 100 just sends down-chain resource on PDCCH to be permitted.If eNB 100 has speech frame to send, eNB 100 sends semi-persistent resource allocation, if there is the SID frame to send, sends the perishability resource and distributes.As long as interim when overtime, also have data to send, semi-persistent resource allocation just effectively, and if interimly when this is overtime do not have data to send, this semi-persistent resource allocation just stops.Can use identical or different overtime periods for down link and up link.ENB 100 also can, before overtime period, come explicitly to stop semi-persistent resource allocation by UE 116, sending signaling.Therefore, when sending, UE 116 can allocate fast down-chain resource when no longer including data.
In a kind of design, eNB 100 can send down link at any time to be permitted, and UE 116 monitoring PDCCH have sent the down link allowance to this UE in order to judge whether.In the another kind design, eNB 100 only sends down link in some subframe to be permitted, and these subframes also can be called the reception subframe.116 of UE monitor PDCCH to judge whether having sent the down link allowance to this UE during receiving subframe.The discontinuous reception (DRX) of UE 116 is supported in this design.
For down link, semi-persistent resource allocation indication particular downlink resource (such as, particular resource block and specific sub-frame), send data to UE 116 in these resources.Semi-persistent resource allocation is also indicated one or more specific MCS, on the down-chain resource permitting, sending data.UE 116 is according to MCS pre-configured in each subframe, and blind decoding is carried out in the transmission that it is received, and wherein, in each subframe, to this UE, sends data.As another kind, select, eNB 100 will signal for the MCS that sends data UE 116, and the transmission that UE 116 receives it according to the MCS notified is decoded.
For down link, eNB 100 use Cell Radio Network Temporary Identifier/Identity, Cell-RNTI symbols (C-RNTI) or some other unique identifier of distributing to UE 116 send data to UE 116.This makes UE 116 can determine clearly that it is that the data-oriented frame is wanted the recipient who arrives.In a kind of design, eNB100 is Frame generation cycle redundancy check code (CRC), then with the C-RNTI of UE 116, this CRC is carried out to mask, then the specific CRC of UE is appended on Frame, then Frame and the specific CRC of UE are sent to UE 116.In the another kind design, the C-RNTI of eNB 100 use UE 116 carries out scrambling to Frame, then the frame of scrambling is sent to UE 116.
