Description
Technical field
The present invention relates to field of wireless communication, more specifically, relate to a kind of scheduling information uploading method for multi-carrier reinforced uplink access system.
Background technology
The enhanced uplink connecting system is commonly referred to as HSUPA (High Speed UplinkPacket Access; High speed uplink packet inserts); Be intended to technology through the advanced person and improve the efficient of up link, with effective support web browse, video, multimedia messages and other IP-based business.
At present, 3GPP (3G (Third Generation) Moblie partnership projects tissue) has accomplished the standardization effort of TD-SCDMA enhanced uplink connecting system.Be applicable to single carrier TD-SCDMA system.Increased a kind of transmission channel E-DCII (enhanced uplink dedicated transmission channel) in the enhanced uplink connecting system newly, the TTI of E-DCH (Transmission Time Interval) is 5ms.The grouping that is mapped on the E-DCH transmission channel is called MAC-e PDU (enhancing media access control protocol data unit).
The physical channel relevant with E-DCH has:
E-UCCH (enhanced uplink control channel); It is physical layer control channel; It is carried in the physical layer indication territory of E-PUCH; The control information of carrying comprises E-TFCI (indication of enhanced uplink transformat is in order to indicate current transport block length) and HARQ information (comprising process ID and number of retransmissions information);
E-AGCH channel (E-DCH absolute grant channel) is a control channel, is used for NodeB (base station) to UE (User Equipment, user terminal) transmission authorization message;
E-PUCH (the E-DCH uplink physical channel is claimed the enhanced uplink physical channel again) is a Traffic Channel, is used for UE and carries the E-DCH transport channel data, and the information that auxiliary dispatching is correlated with is also in this channel;
(E-DCH inserts ascending control channel to E-RUCCH at random; Be that enhanced uplink random inserts ascending control channel), be physical layer control channel, being used for UE is not having under the situation of authorizing; The relevant information of transmission auxiliary dispatching, E-RUCCH uses the Physical Random Access Channel resource; And
E-HICH (E-DCH hybrid automatic repeat request indication channel) is a physical layer control channel, is used for Node B and carries HARQ (mixing automatic repeat requests) indication information.
The enhanced uplink access service is divided into dispatching services and non-scheduling service by the difference of scheduling mode; Wherein, The resource of non-scheduling service is that by RNC (radio network controller) UE distributes, and the method for salary distribution is with existing dedicated channel allocation mode, and in dispatching services; For Node B distributes the enhanced uplink resource pool, is single UE Resources allocation by Node B by SRNC.
In dispatching services; UE need report the scheduling of some information with auxiliary Node B; These information are called schedule information SI (Scheduling Information), and Fig. 1 is the diagrammatic sketch of the content of schedule information, wherein; Comprise the path loss information SNPL of UE buffering area occupied information BO, power headroom UPH, service/adjacent sub-district, have 23 bits.The total buffer state is the sum total of data volume to be sent in the UE logic channel buffering area among the buffering area occupied information BO; The highest priority logical channel buffer state is the current data volume that data highest priority logical channel buffering area to be sent is arranged, and highest priority logical channel ID indicates data highest priority logical channel to be sent number.Node B is that UE distributes adequate resources according to BO information mainly, comprises channel resource and power resource; Serve/the path loss information of adjacent sub-district and the restrictive condition that power margin information then provides resource authorization, this sub-district that Node B need report according to UE and the path loss information of adjacent sub-district limit scheduling of resource with the interference of control to adjacent sub-district; Node B is that the authorization power that UE distributes can not surpass the power headroom that UE reports.
When UE had upstream data to send, UE just possibly trigger the transmission of schedule information.When UE does not authorize, will send schedule information through the E-RUCCH channel, shown in Fig. 2 a, the situation that UE does not have to authorize comprises that the E-DCH of UE carries and sets up initially, UE has data to need transmission; Perhaps UE does not continue in a period of time to obtain the authorization after the last time, mandate used up.When UE had the E-PUCH resource of mandate, schedule information and business datum were sent through the E-PUCH channel together, and the schedule information of 23 bits will be added on the end of E-DCH data, shown in Fig. 2 b.Remaining bits after buffer data is multiplexed into MAC-e PDU (enhancing media access control protocol data unit); It is the bit after MAC-e PDU transport block length deducts packets headers (data description) and data division length; Add the DDI0 field during more than or equal to 29 bits; Wherein fill in 111111, be used for the transmission of explicit indication schedule information; Remaining bits after buffer data is multiplexed into MAC-e PDU (enhancing media access control protocol data unit) does not have the DDI0 indication during less than 29 bits but greater than 23 bits, only adds schedule information at the data end.Node B can judge among this MAC-e PDU whether carried schedule information according to the total length of MAC-e PDU and the length of data description and data division fully.When only having transmitted schedule information among the MAC-e PDU, whether Node B can only transmit schedule information according to the identification of the E-TFCI among the E-UCCH.
For the further throughput of raising system, existing single carrier enhanced uplink system will introduce the multicarrier characteristic, and the system of N carrier wave will have N times to the throughput of single-carrier system in theory.When introducing the multicarrier characteristic; With the consideration that has multiple framework; Wherein a kind of feasible framework is a multicarrier binding mechanism, and promptly RNC is in advance for UE distributes a plurality of carrier resources, and Node B can authorize one or more carrier resources (these carrier resources are that RNC is pre-configured) for single UE in a TTI (Transmission Time Interval); UE can send the E-DCH data simultaneously on a plurality of carrier waves in a TTI, the data block that each carrier wave sends is independently.Another kind of framework is a RNC distributing carrier wave resource not in advance, and Node B can select one or more carrier resources for single UE in a TTI (Transmission Time Interval).
After introducing multicarrier mechanism, need carry out many-sided improvement to single carrier enhanced uplink connecting system, make it can adapt to that multicarrier sends simultaneously and the situation of carrier wave dynamic dispatching.

Wherein, long schedule information comprises public information and carrier wave customizing messages, and minor degree information only comprises the carrier wave customizing messages.
Wherein, after MAC-e PDU transport block length is completion logic channel buffer data multiplex, the transport block length of gained is quantized to the length after certain value in the E-DCH transport block length form of system's appointment.
If remaining bits can be held long schedule information, then user terminal adds long schedule information to strengthen media access control protocol data unit afterbody.
And if remaining bits is more than or equal to 29 bits; Then add the schedule information indication at the head that strengthens media access control protocol data unit; And user terminal adds long schedule information to strengthen media access control protocol data unit afterbody, and wherein, schedule information is designated as 111111.
In addition, if remaining bits can not be held long schedule information, but can hold minor degree information, then user terminal adds minor degree information to the afterbody that strengthens media access control protocol data unit.
Wherein, public information is that user terminal is mapped to the logic channel buffering area occupied information on the E-DCH, comprising: total buffer state, highest priority logical channel buffer state and limit priority logical message ID.
The carrier wave customizing messages is the schedule information of sending the carrier wave at schedule information place, comprising: the path loss of service/adjacent sub-district and the user terminal power headroom on this carrier wave.
Report method according to multi-carrier reinforced uplink access system schedule information of the present invention can also may further comprise the steps: for public information is provided with the public information transmission timer, and the carrier wave customizing messages that is respectively on each carrier wave is provided with carrier wave customizing messages transmission timer.
When user terminal sends the length schedule information on authorization resources, restart public information transmission timer and the carrier wave customizing messages transmission timer that sends this schedule information place carrier wave; When user terminal sends minor degree information on authorization resources, restart the carrier wave customizing messages transmission timer of place carrier wave; After the public information transmission timer is overtime; If the remaining bits of accomplishing on the carrier wave in ensuing Transmission Time Interval in a plurality of mandate carrier waves behind the data multiplex can be held long schedule information; Then user terminal preferentially selects this carrier wave to send long schedule information; Otherwise user terminal selects a carrier wave preferentially to send long schedule information at random, and then considers data multiplex; And after carrier wave customizing messages transmission timer was overtime, user terminal is the preferential schedule information of sending on this carrier wave, and then considers data multiplex.
Wherein, the carrier wave customizing messages transmission timer on public information transmission timer and each carrier wave is the UE configuration by high level.
The start-up course of public information transmission timer or carrier wave customizing messages transmission timer comprises following processing: if public information transmission timer or carrier wave customizing messages transmission timer are activated; At first reset public information transmission timer or carrier wave customizing messages transmission timer of user terminal then; Restart public information transmission timer or carrier wave customizing messages transmission timer then; Otherwise user terminal directly starts public information transmission timer or carrier wave customizing messages transmission timer.
Fig. 4 a is the diagrammatic sketch of the long schedule information among the present invention.Shown in Fig. 4 a; Consistent with the schedule information in the existing single carrier enhanced uplink connecting system; Comprise all 5 information, totally 23 bits: total buffer state, highest priority logical channel state, highest priority logical channel ID, service/adjacent sub-district path loss, uplink power margin.Wherein total buffer state, highest priority logical channel state, highest priority logical channel ID should not distinguish carrier wave, are called public information.
Fig. 4 b is the diagrammatic sketch of the minor degree information among the present invention.Shown in Fig. 4 b, wherein only comprise needs and distinguish the information that carrier wave reports, be called the carrier wave customizing messages, totally 10 bits comprise service/adjacent sub-district path loss, uplink power margin.
Ascending resource is limited in the TD-SCDMA system, and schedule information can't be sent through dedicated channel, but on the E-PUCH channel, adopts the send mode of doing one's best, and is called " incidentally " mode.That is, if the remaining bits (hereinafter to be referred as " remaining bits ") that buffer data is multiplexed into behind the MAC-e PDU can be held schedule information, UE need add schedule information to MAC-e PDU data end.The length of remaining bits length=MAC-e PDU transport block length-data description (packets headers) and data division wherein.Be divided into 2 kinds of situation: if remaining bits can be held long schedule information, UE adds the length schedule information to MAC-e PDU afterbody; Can hold minor degree information if remaining bits can not be held long schedule information, UE adds minor degree information to MAC-e PDU afterbody.Under first kind of situation, in order to be consistent,, add DDI0 at MAC-e PDU head if remaining bits can be held 29 bits with single carrier HSUPA system, long schedule information is added on the end.The mechanism of in remaining bits, sending schedule information is called " incidentally " mechanism.
System provides E-DCH transport block length form; UE need quantize to the E-DCH block length that obtains on certain the immediate value in the form after accomplishing data multiplex; As final E-DCH transport block length, the E-DCH transport block length that the present invention mentioned all is meant the result after the given transport block length value of the system of quantizing to.
Public information can be sent on arbitrary mandate carrier wave, and transmission separately of public information, always follows the transmission of carrier wave customizing messages.
No matter be in long schedule information or the minor degree information; Carrier wave information specific wherein must be consistent with the carrier wave that current MAC-e PDU sends the place, promptly must be service/adjacent sub-district path loss, the uplink power margin information that sends on the carrier wave at this schedule information place.So that Node B identification.
A MAC-e PDU comprises a kind of schedule information at most: long schedule information or minor degree information.According to said method, UE always preferentially sends long schedule information, the real-time of guaranteeing buffer information of maximum possible.
Can not get triggering during for fear of schedule information length, that is, the transmission of not enough schedule information when remaining bits is long, high-rise is UE configuration timer value T.UE is provided with a timer to public information, is called the public information transmission timer, and timer duration is T, and the effect of this timer is to guarantee that public information is sent out once in time T at least; To each carrier wave a timer is set respectively; Be called the specific timer of carrier wave i; Timer duration is T, and wherein i is used to distinguish different carrier waves, and scope is [1; The maximum carrier number that UE can send simultaneously], this timer is used to guarantee that the specific schedule information of this carrier wave is sent out once at least in time T.Timer T can set up in the correlated process of E-DCH resource configuration in RRC (Radio Resource control) and give UE.
The concrete implementation procedure of timer mechanism is, when user terminal sends new public information on authorization resources, if the public information transmission timer is in operation (that is, being activated), and this timer that then resets, and restart, regularly length is T.After the public information transmission timer is overtime, user terminal will initiatively send long schedule information.When user terminal sent long schedule information on the carrier resource of a mandate, the public information transmission timer was incited somebody to action simultaneously, is restarted respectively with the specific timer of this carrier wave.When UE initiatively sends long schedule information, need take into account the multiplexing of buffer data, and carry out certain optimization.If certain authorizes the remaining bits of accomplishing data multiplex on the carrier wave and carrying out after transport block length quantizes can hold long schedule information among this TTI, so preferentially select this carrier wave to send long schedule information; If among this TTI on all carrier waves the remaining bits behind the data multiplex all can not hold long schedule information, UE selects a carrier wave preferentially to send long schedule information at random so, just considers data multiplexing then.
When user terminal sends the specific schedule information of new carrier wave on the carrier resource of a mandate (schedule information of transmission can be long schedule information or minor degree information); If the specific timer of this carrier wave is in operation (promptly; Be activated); UE this timer that resets, and restart this timer, regularly length is T.When the specific timer expiry of this carrier wave, user terminal will initiatively send schedule information on this carrier wave.User terminal need be optimized the transmission of schedule information in this case, and UE can select to send long schedule information or minor degree information, and the foundation of selection is to optimize data multiplexing as far as possible.The remaining bits of MAC-e PDU can be held long schedule information on this carrier wave, and UE will send out schedule information long; Can hold minor degree information if remaining bits can not be held long schedule information, UE will initiatively send minor degree information so; If remaining bits can not be held minor degree information, UE will preferentially send minor degree information so, just consider data multiplexing then.
In a TTI, when the specific timer of the carrier wave of public information transmission timer and some carrier waves is all overtime, can be chosen in and sends long schedule information on this carrier wave.Various optimizations when initiatively sending schedule information all realize that based on UE inside purpose is to reduce the waste of resource as far as possible.The present invention does not limit these optimization methods.When initiatively sending the length schedule information, whether user terminal still need insert schedule information indication 111111 according to the rule judgment of original system in packets headers.
When because authorization resources is less, UE can't the multiplexes logical channels data, in the time of can only sending schedule information, and can only send long schedule information this moment, and Node B just can discern through the E-TFCI among the E-UCCH and wherein only comprise a long schedule information.
Because the TD-SCDMA ascending resource is limited; Node B can not be the UE authorization resources at each TTI; Thereby in the timer mechanism provided by the invention, if timer expiry the time, UE does not have authorization resources; UE will wait for the mandate of Node B so, after obtaining authorization resources, carry out the active of schedule information and send.UE also can send schedule information in non-scheduling MAC-e PDU.
Fig. 5 is the flow graph of scheduling information uploading method for multi-carrier reinforced uplink access system according to an embodiment of the invention, and wherein, 5-1 representes long schedule information, and 5-2 representes minor degree information.As shown in Figure 5, may further comprise the steps:
S502, UE have incidentally sent long schedule information on carrier wave 1, on carrier wave 2, incidentally sent minor degree information, have started public information transmission timer, carrier wave 1 specific timer, carrier wave 2 specific timers respectively;
S504; On carrier wave 1, incidentally send minor degree information; On carrier wave 2, incidentally send long schedule information, on carrier wave 3, incidentally send minor degree information, restart carrier wave 1 specific timer, public information transmission timer, carrier wave 2 specific timers and carrier wave 3 specific timers respectively;
S506, carrier wave 1 specific timer and public information transmission timer are overtime respectively, do not have authorization resources this moment; And
S508, UE has obtained authorization resources, and UE is chosen on the carrier wave 1 and sends long schedule information, has upgraded the specific schedule information of public information and carrier wave 1 to Node B.
In single carrier enhanced uplink connecting system; High-rise for the UE side is provided with a timer T-WAIT, when UE starts this timer, timer expiry after the suitable expiration of the last time mandate; UE will initiate to insert at random, send schedule information through the E-RUCCH channel.T-WAIT is exactly that UE initiates under the situation of authorizing the time of delay of access at random from having to authorize not have, and is used to limit too much access at random, and its value has reflected the average scheduling frequency of Node B.This mechanism equally also is applicable to multicarrier system.Method provided by the present invention is applicable to the situation of mandate, and before T-WAIT was overtime, all timers were all effective, in case T-WAIT is overtime, these timers will automatically reset.
In sum, the present invention divides into long schedule information and minor degree information with schedule information, considers that mainly buffer information belongs to public information, should not distinguish carrier wave, under the situation of resource-constrained, can avoid the transmission that repeats of this information, saves resource.The present invention is directed to long and short schedule information " incidentally " mechanism and " the initiatively sending " mechanism that relies on timer are provided respectively, these two mechanism itself complement each other, and work in coordination.The former is used for the transmission schedule information of under the situation of not wasting system resource, doing one's best, and the latter is in order to ensure certain real-time.
More than be merely the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
