Description

Data communications method in the wireless communication system

Technical field

The present invention relates to a kind of wireless communication system, and more specifically, relate to the data communications method in a kind of wireless communication system.

Background technology

At the multicarrier that uses such as OFDM (OFDMA), perhaps in the wireless communication system of single-carrier frequency division multiple access (SC-FDMA), radio resource is the set of continuous subcarrier and by the T/F zone definitions on the two-dimentional spheroid.The T/F zone is the rectangular in form of cutting apart by time and sub-carrier coordinates.In other words, a T/F zone can be the rectangular in form of cutting apart by at least one symbol on the time shaft and a plurality of subcarriers on the frequency axis.This T/F zone can be assigned to the up link that is used for special user equipment (UE), and perhaps the base station can be to special user equipment launch time-frequency field in down link.For this T/F zone of definition on two-dimentional spheroid, should provide the number of the continuous subcarrier that begins from the point of skew and the number of OFDM symbol with relative reference point.

Current evolved universal mobile communication system (E-UMTS) in question is used the 10ms radio frame that comprises 10 subframes.Just, a subframe comprises two continuous time slot.A time slot has the length of 0.5ms.Moreover a subframe comprises a plurality of OFDM symbols, and the part in a plurality of OFDM symbol (for example, first symbol) can be used for the emission of L1/L2 control information.

Fig. 1 illustrates the example of the structure of the physical channel that uses among the E-UMTS.In Fig. 1, a subframe comprises L1/L2 control information emitting area (dash area) and data transmission zone (non-shaded portion).

Fig. 2 illustrates the conventional method of the emission data among the E-UMTS.In E-UMTS, be used to improve throughput as one in the data re-transmitting scheme mixed automatic repeat request (HARQ) scheme, realize desired communication thus.

With reference to Fig. 2, transmitting down link schedule information (being called as " DL schedule information " hereinafter) is come according to the DL L1/L2 control channel of HARQ scheme by for example physical downlink control channel (PDCCH) in the base station, with to subscriber equipment emission data.The DL schedule information comprise user equipment identifiers (UE ID) or subscriber equipment group identifier (group ID), be allocated for position and duration (duration) (duration of resource assignation and assignment) information, modulating mode, load information, emission parameter, HARQ procedural information, redundancy versions and the new data indicator of radio resource of the emission of down link data such as the MIMO relevant information.

In order to notify by PDCCH which subscriber equipment to have launched the DL schedule information for, launch user equipment identifiers (perhaps group identifier), for example, radio net temporary identifier (RNTI).RNTI can be classified as special-purpose RNTI and public RNTI.Special-purpose RNTI is used for being registered to the subscriber equipment emission data of base station and receiving data from the subscriber equipment that its information is registered to the base station to its information.If carry out with because of the communicating by letter of the unregistered subscriber equipment that is not assigned with special-purpose RNTI to the base station of its information, then use public RNTI.Alternatively, public RNTI is used for information emission that is used for a plurality of subscriber equipmenies jointly and the reception such as system information.For example, the example of public RNTI comprises RA-RNTI and the T-C-RNTI that uses by Random Access Channel (RACH) during random access procedure.User equipment identifiers or group identifier can be by launching by CRC (cyclic redundancy check (CRC)) mask (masking) type in the DL schedule information of PDCCH emission.

The subscriber equipment that is arranged in specific cell uses their RNTI information and monitors PDCCH by the L1/L2 control channel, and if they successfully carry out the CRC decoding by their RNTI, then receive the DL schedule information by corresponding PDCCH.Subscriber equipment receives down link data to its emission by the physical down link sharing channel (PDSCH) by the indication of the DL schedule information that receives.

Scheduling method can be classified as dynamic dispatching pattern and static state or semi-persistent scheduling pattern.When need be for specific user equipment allocation up link or down-chain resource, the dynamic dispatching pattern will be by PDCCH to specific subscriber equipment emission schedule information.The static scheduling pattern refers to the base station during the initial call of setting up such as radio bearer is set up, statically to user equipment allocation down link or uplink scheduling information.In this article, term " static scheduling " has the implication identical with " semi-persistent scheduling ".

In the situation of static scheduling, subscriber equipment is not using under the situation of the DL schedule information of base station assigns or UL scheduling, uses the schedule information of distributing to the base station in advance to launch or receives data.For example, if the base station is set at specific subscriber equipment transformat " B " and the period " C " that allows during subscriber equipment is set up according to radio bearer in advance, come receiving downlink data by RRC signal and radio resource " A ", then subscriber equipment can use information " A ", " B " and " C " to receive the down link data from base station.Similarly, though at subscriber equipment in the base station data conditions, subscriber equipment can be according to the uplink scheduling information of prior distribution, uses the radio resource of predefined to come transmit uplink data.Static scheduling is can be applied to well such as its traffic carrying capacity of voice communication scheduling method of the service of rule.

The AMR codec that uses in the voice communication, promptly the speech data that generates by audio coder ﹠ decoder (codec) has special feature.That is, speech data is classified as talkburst and mourns in silence the period.Talkburst refers to the speech data period that generates when the people is actual to speak, and the period of mourning in silence refers to the speech data period that generates when the people does not speak.For example, every 20ms generates the packets of voice that comprises the speech data in the talkburst, and every 160ms generates the silence packet (SID) that comprises the speech data in the period of mourning in silence.

If static scheduling is used for voice communication, then radio resource will be set up according to talkburst in the base station.That is, the base station will use feature that every 20ms generates packets of voice in advance during call setup, set up by the interval of 20ms to be used for to the subscriber equipment emission with from the radio resource of subscriber equipment receiving uplink or down link data.Subscriber equipment uses radio resource receiving downlink data or the transmit uplink data of setting up with every 20ms in advance.

Summary of the invention

As indicated above, when up link of using static scheduling to dispatch to be used for voice communication or down-chain resource, needed is that the period of mourning in silence should be converted into talkburst.On the other hand, if talkburst is converted into the period of mourning in silence, then neededly be, the base station should change the radio resource allocation information of prior distribution apace, with the radio resource of the feature of redistributing the suitable period of being changed.Except the conversion mutually of mourning in silence between period and the talkburst, if following incident takes place, for example, conversion between the AMR codec mode during the voice communication, and wherein in the PDCP entity, generate the period of full header packets and wherein generate conversion between period of header compression grouping, following problem has then appearred: according to static scheduling, use the radio resource that distributes in advance can not launch or be received in the data that generate after the as above incident generation efficiently.

In wireless communication system, can come executive communication by the mode that dynamic dispatching and static scheduling is applied to simultaneously a subscriber equipment.For example, if carry out the voice communication of serving according to VoIP according to the HARQ scheme, then static scheduling is applied to the initial transmissions grouping, and dynamic dispatching is applied to packet retransmission.Equally, if subscriber equipment uses two or more services simultaneously, then static scheduling can be applied to one the service and dynamic dispatching can be applied to another service.In these situations, neededly be, subscriber equipment should be discerned clearly: whether the schedule information to its emission depends on scheduling method, and perhaps the schedule information configuration that is used for static scheduling still is used for emission/reception packet retransmission, and perhaps which kind of service is schedule information be used for.

Fig. 6 is the flow chart of process of the method for diagram emission data according to an embodiment of the invention.According to the embodiment of Fig. 6, subscriber equipment (UE) receives the SRB grouping according to dynamic dispatching when receiving speech data (VoIP grouping) according to static scheduling.Hereinafter, will only carry out necessary description for understanding embodiments of the invention, and the description that is used for the general process that signal post needs between network and subscriber equipment will be omitted.

With reference to Fig. 6, eNode B (eNB) distributes to subscriber equipment [S61] with two user equipment identifiers.The example of two user equipment identifiers comprises C-RNTI and SPS-C-RNTI (semi-persistent scheduling).Yet these two user equipment identifiers will be not limited to above example.For example, interim C-RNTI and RA-RNTI can be used as two user equipment identifiers.These two user equipment identifiers can be given subscriber equipment by network allocation during random access procedure, call establishment or radio bearer (RB) sets up process.And these two user equipment identifiers can side by side or individually be assigned with.

ENode B launches initial transmissions VoIP grouping V1[S62 by PDSCH to subscriber equipment].It in the situation of using the HARQ scheme is not the packets of voice of packet retransmission that initial transmissions VoIP grouping V1 refers to.If failing, subscriber equipment receives this initial transmissions VoIP grouping V1, promptly, if subscriber equipment fails initial transmissions VoIP grouping V1 is decoded, then subscriber equipment is launched NACK signal [S63] by physical uplink control channel (PUCCH) to eNode B.Static scheduling is used for transmitting and receiving of initial transmissions VoIP grouping V1 and NACK signal.In other words, as long as receive initial transmissions VoIP grouping V1 or emission NACK signal (or ack signal), then subscriber equipment uses the schedule information of distributing to eNode B in advance and does not receive DL schedule information or UL schedule information from eNode B.Therefore, subscriber equipment need be in step S62 and S63 receiving scheduling information.

As indicated above, when subscriber equipment receives initial transmissions VoIP grouping V1 or emission NACK signal (or ack signal), use static scheduling.Yet dynamic dispatching is used for the emission by the repeating transmission VoIP grouping of eNode B.Therefore, after emission NACK signal, subscriber equipment at first receiving scheduling information to receive packet retransmission.For this reason, the PDCCH of user equipment monitors L1/L2 control channel.

In Fig. 6, eNode B launches first schedule information [S64] by PDCCH to subscriber equipment.First schedule information is distributed to subscriber equipment according to dynamic dispatching with up link and/or downlink channel resources.First schedule information can comprise DL schedule information and UL schedule information.Suppose that first schedule information is to be used for to subscriber equipment emission SRB packet scheduling information.

Because subscriber equipment is launched NACK in step S63, be used for initial transmissions VoIP grouping, so user equipment monitors PDCCH is to receive the repeating transmission VoIP grouping relevant with initial transmissions VoIP grouping V1 from eNode B emission.Yet, if be not used for receiving the VoIP packet scheduling information of retransmitting by the PDCCH emission, but launched first schedule information that is used to launch the SRB grouping as step S64, then according to correlation technique, subscriber equipment may be misinterpreted as first schedule information and be used for receiving the VoIP packet scheduling information of retransmitting.In this case, subscriber equipment uses first schedule information that the initial transmissions SRB that receives grouping is defined as retransmitting the VoIP grouping, and according to the HARQ scheme should divide into groups and initial transmissions VoIP packet assembling with the trial packet recovery, mistake has appearred thus.

In order to prevent this mistake, according to the embodiment of Fig. 6, the schedule information of launching by PDCCH comprises the indication information of indication according to specific scheduling method emission corresponding scheduling information.In the embodiment of Fig. 6, two user equipment identifiers that distribute among the step S61 are used as indication information.In other words, C-RNTI can be used as schedule information is launched in indication according to dynamic dispatching information, and SPS-C-RNTI can be used as following information, and it is used to indicate according to static scheduling launches the schedule information that is used to launch the packet retransmission relevant with the initial transmissions grouping.Just, in Fig. 6, it is to be used for schedule information that the repeating transmission VoIP grouping of the initial transmissions VoIP grouping that is used for launching according to static scheduling is launched that SPS-RNTI is used to indicate corresponding scheduling information.C-RNTI or SPS-C-RNTI can be by being included in the schedule information or utilizing at least a portion schedule information and it is carried out the CRC mask launch.

In Fig. 6, if comprise C-RNTI in the schedule information that in step S64, receives, then subscriber equipment recognizes that this schedule information is the schedule information according to dynamic dispatching, and uses this schedule information to receive the initial transmissions SRB grouping S1[S65 that launches from eNode B].

ENode B launches second schedule information by PDCCH to subscriber equipment, and with emission and the related packet retransmission V2 of initial transmissions VoIP grouping V1, wherein, second schedule information comprises SPS-C-RNTI[S66].If subscriber equipment receives second schedule information that comprises SPS-C-RNTI, then subscriber equipment uses second schedule information to receive the repeating transmission VoIP grouping V2[S67 that launches from eNode B].Repeating transmission VoIP grouping V2 and initial transmissions VoIP grouping V1 combination that subscriber equipment will receive according to the HARQ scheme are to recover VoIP grouping [S68].If subscriber equipment successfully recovers the VoIP grouping, then subscriber equipment is to eNode B emission ack signal [S69].The VoIP grouping refers to the packet of attempting to be transmitted into from eNode B subscriber equipment.The VoIP grouping is divided into initial transmissions VoIP grouping V1 and retransmits VoIP grouping V2, and is launched into subscriber equipment according to the HARQ scheme subsequently.

In the embodiment of Fig. 6, first schedule information and second schedule information may further include that can to discern according to first schedule information and second schedule information be the initial transmissions grouping or the identifying information of packet retransmission from the packet that eNode B is transmitted into subscriber equipment.This identifying information can be included in first schedule information and second schedule information in the following way: promptly, the specific fields of first schedule information and second schedule information is set to the value of having set in advance.For example, can discern first packet retransmission, second packet retransmission and the 3rd repeating transmission grouping in the following way: promptly, the particular value such as 1,2 and 3 is set in redundancy versions (RV) field that comprises in first schedule information and second schedule information.Except the RV field, other fields that comprise in first schedule information and second schedule information, for example, at least one of HARQ process id field, format fields, MCS field, NDI (new data indicator), TPC field, " cyclic shift that is used for DMRS " field, " TX antenna " field and CQI request field is set to particular value, makes this value can be used as identifying information.

In the embodiment of Fig. 6, if for example the specific fields that comprises in the schedule information of HARQ process id field is set to the particular value of predefined, the subscriber equipment that has then received corresponding scheduling information thinks that this corresponding scheduling information is the configuration information that is used for static scheduling.Therefore, the subscriber equipment that has received the schedule information that comprises the HARQ process id field that is set to particular value uses corresponding scheduling information to come according to static scheduling emission or reception data, be released until radio bearer foundation or call setup, perhaps other schedule informations are updated.

In this case, received and comprise and be set to the schedule information that is used for corresponding Transmission Time Interval (TTI) except the subscriber equipment of the schedule information of the HARQ process id field of the value this particular value, perhaps used schedule information to arrive the emission maximum number of times until the HARQ processor relevant with this schedule information.

Fig. 7 is the flow chart of process that illustrates the method for emission data according to another embodiment of the present invention.According to the embodiment of Fig. 7, by the mode identical with the embodiment of Fig. 6, subscriber equipment (UE) receives the SRB grouping according to dynamic dispatching when receiving speech data (VoIP grouping) according to static scheduling.The embodiment of Fig. 7 identification is according to the HARQ scheme of dynamic dispatching with according to the HARQ scheme of static scheduling.Hereinafter, will only carry out necessary description for understanding embodiments of the invention, and the description that is used for the general process that signal post needs between network and subscriber equipment will be omitted.

As indicated above, when subscriber equipment receives initial transmissions VoIP grouping V1 or emission and is used for the NACK signal (or ack signal) of initial transmissions VoIP grouping, use static scheduling.Yet dynamic dispatching is used for retransmitting the VoIP grouping by eNode B emission.Therefore, after emission was used for the NACK signal of initial transmissions VoIP grouping, subscriber equipment should at first pass through PDCCH receiving scheduling information, retransmitted the VoIP grouping to receive from eNode B.

If subscriber equipment receives for example grouping of SRB grouping according to dynamic dispatching when carrying out voice communication, then subscriber equipment need be by discerning being used to transmit and receive retransmit the schedule information that the VoIP grouping launch and be used to receive the schedule information that SRB divides into groups to launch, thereby receive this schedule information.For this reason, in the embodiment of Fig. 7, be used for transmitting and receiving and retransmit the VoIP grouping and HARQ process id field that the schedule information of emission comprises is set at least one particular value.In the embodiment of Fig. 7, if HARQ process id field is set to " 101 ", " 110 " and " 111 ", then corresponding scheduling information is retransmitted the VoIP grouping and the schedule information of emission corresponding to being used to transmit and receive.ENode B and subscriber equipment can be dispatched, make HARQ process id field can during initial access process, call establishment or RB set up process, be set to particular value in advance, retransmit the VoIP grouping and the schedule information of emission so that expression is used to transmit and receive.

With reference to Fig. 7, eNode B (eNB) is to subscriber equipment (UE) emission initial transmissions VoIP grouping V1[S71].It not is to be the voice data packet of packet retransmission that initial transmissions VoIP grouping refers to.If subscriber equipment receives initial transmissions VoIP grouping with failing, then subscriber equipment is to eNode B emission NACK[S72].

ENode B launches first schedule information by PDCCH to subscriber equipment, with emission initial transmissions SRB grouping S1[S73].If the value of setting in the HARQ process id field that comprises in first schedule information is not the particular value of predefined, then subscriber equipment recognizes that first schedule information is not to be used for the related packet retransmission with initial transmissions VoIP grouping V1.The value of dispatching in advance because the HARQ process id field of first schedule information is set to " 000 ", so subscriber equipment uses first schedule information to receive the initial transmissions SRB grouping S1[S74 that launches from eNode B].If initial transmissions SRB grouping S1 is not successfully decoded, then subscriber equipment is to eNode B emission NACK[S75].

ENode B launches second schedule information by PDCCH to subscriber equipment, so that to the subscriber equipment emission first repeating transmission VoIP grouping V2 related with initial transmissions VoIP grouping V1, wherein second schedule information comprises the HARQ process id field that is set to " 101 ", and " 101 " are [S76] in the particular value of predefined.After the HARQ process id field of identification second schedule information had been set to the value of predefined, it was the schedule information that is used for the packet retransmission related with initial transmissions VoIP grouping V1 that subscriber equipment can be discerned second schedule information.

ENode B retransmits VoIP grouping V2 according to second schedule information to subscriber equipment emission first, and subscriber equipment uses second schedule information to receive the first repeating transmission VoIP grouping V2[S77].Subscriber equipment is retransmitted VoIP grouping V2 according to the HARQ scheme with first and is made up with initial transmissions VoIP grouping V1, and to grouping decode [S78].If subscriber equipment fail to the VoIP packet decoding, then subscriber equipment is to eNode B emission NACK[S79].

ENode B launches the 3rd schedule information by PDCCH to subscriber equipment, so that to subscriber equipment emission and the initial transmissions SRB related packet retransmission of S 1 of dividing into groups, wherein the 3rd schedule information comprises the HARQ process id field [S80] that is set to " 000 ".ENode B retransmits SRB grouping S2 according to the 3rd schedule information to the subscriber equipment emission, and subscriber equipment uses the 3rd schedule information to receive the first repeating transmission SRB grouping S2[S81].Repeating transmission SRB that subscriber equipment will receive grouping S2 and initial transmissions SRB grouping S1 combination, and to SRB divide into groups to decode [S82].If subscriber equipment is successfully to packet decoding, then subscriber equipment is to eNode B emission ACK[S83].

ENode B launches the 4th schedule information by PDCCH to subscriber equipment, so that the related packet retransmission of VoIP grouping V2 is retransmitted in emission and first, wherein, the 4th schedule information comprises the HARQ process id field [S84] that is set to " 110 ".After the HARQ process id field of identification the 4th schedule information had been set to the value of predefined, subscriber equipment can recognize that the 4th schedule information is the schedule information that is used for the packet retransmission related with the first repeating transmission VoIP grouping V2.

To the subscriber equipment emission second repeating transmission VoIP grouping V3, it is the packet retransmission of the first repeating transmission VoIP grouping V2 to eNode B according to the 4th schedule information, and subscriber equipment uses the 4th schedule information to receive the second repeating transmission VoIP grouping V3[S85].Subscriber equipment makes second to retransmit VoIP grouping V3, first and retransmit VoIP grouping V2 and initial transmissions VoIP grouping V1 combination with one another according to the HARQ scheme, and the grouping decode [S86] to VOIP.If subscriber equipment successfully divides into groups to decode to VoIP, then subscriber equipment is to eNode B emission ACK[S87].
