Description
Technical field
The present invention relates to the mobile communication technology field, be specifically related to mixed automatic retransferring method in a kind of multi carrier wave high-speed downlink grouping access.
Background technology
In order to adapt to the demand of growing data service, 3GPP Rlease 5 (third generation partnership project version 5) has introduced HSDPA (high speed downlink packet access) technology, to improve the message transmission rate of down direction.The HSDPA technology is applicable to WCDMA FDD (broadband CDMA frequency divided duplex), UTRA TDD (universal terrestrial radio access time division duplex) and three kinds of different modes of TD-SCDMA (time slot-S-CDMA) simultaneously.
The key technology that HSDPA adopts comprises: fast packet scheduling, AMC (Adaptive Modulation and Coding) and HARQ (mixing automatic repeat requests).These technology are realized jointly by MAC-hs that is positioned at Node B (base station) (medium access control entity) and the MAC-hs entity that is positioned at UE (subscriber equipment).
Fig. 1 shows the MAC-hs model of UTRAN side, and this entity is positioned at Node B, comprises scheduler module and mixes automatic repeat requests module.
Fig. 2 shows the MAC-hs model of UE side, comprises resetting and disassembling module and mix automatic repeat requests module.
In the MAC-hs of Node B, use the user of HSDPA for each and dispose a HARQ entity, be used for all HARQ processes of leading subscriber, select appropriate H ARQ process transmission MAC-hsPDU (MAC-hs protocol Data Unit).Corresponding with it, the MAC-hs of UE also sets up a HARQ entity, is in charge of corresponding HARQ process, and there is one-to-one relationship in the HARQ process between the two.
Description in the existing protocol is mainly at single carrier, and to any one Transmission Time Interval (TTI), each UE that is scheduled can only transmit a MAC-hs PDU.Scheduler module in the MAC-hs entity of Node B is responsible for determining which UE is scheduled, and for each user who is scheduled constructs a MAC-hs PDU, is delivered to the HARQ entity, then by the suitable process transmission of HARQ entity selection.HSDPA has adopted that multidiameter delay stops and has waited the HARQ agreement.Promptly start a plurality of HARQ processes simultaneously, after using certain HARQ process transmission MAC-hs PDU, before receiving feedback information, can not continue to use any data of this process transmission, but in the feedback information process of certain HARQ process of wait, can use other idle process to continue transmission MAC-hs PDU.The HARQ entity of the UE side soft buffer memory that has been each HARQ course allocation, cache size has determined that the HARQ process can data quantity stored.
The HARQ entity of Node B need be followed following principle when selecting the HARQ process:
1. if the MAC-hs PDU that retransmits must use the HARQ process of using when transmitting this PDU for the first time.
2. if the new MAC-hs PDU that produces, the HARQ process of Xuan Zeing must be idle so, and the data volume of this MAC-hs PDU after through CRC (cyclic redundancy check (CRC)) verification can not be above the cache size of the HARQ process of UE side correspondence.
The major function that the HARQ entity of UE side is realized is as follows:
Judge the HARQ process that the MAC-hs PDU of current transmission uses according to the information of carrying on the control channel, and be new data or data retransmission, and these data are handled accordingly, return acknowledge message ACK or NACK messages NACK to Node B or UTRAN (Universal Terrestrial Radio Access Network road) side simultaneously.
In the existing standard, all at single carrier, for arbitrary TTI, each UE that is scheduled can only start MAC-hs PDU of a HARQ process transmission for the management of HARQ process.And the HSDPA technology is applied in the multicarrier system, make a plurality of carrier waves support HSDPA simultaneously, can further improve downlink transmission data rate.For multi-carrier HSDPA, UE may transmit a plurality of MAC-hs PDU at certain TTI, thereby need to start a plurality of HARQ processes, how to use and manages these HARQ processes, lacks necessary description in the existing protocol.
Therefore, when a logic district has a plurality of carrier waves to be used to support HSDPA, based on the wireless network of existing transmission means and the demand that terminal can't satisfy multi-carrier HSDPA.
Summary of the invention
The purpose of this invention is to provide mixed automatic retransferring method in a kind of multi carrier wave high-speed downlink grouping access, the HARQ management of process realizes the support of HSDPA system to multicarrier only at the shortcoming of single carrier in the prior art HSDPA system to overcome.

Embodiment
Core of the present invention is that by Node B be the HARQ process that the UE that is scheduled sets up predetermined number, and all carrier waves that UE may use are shared these HARQ processes.When needs transmitting high speed down grouped data, select appropriate H ARQ process by the automatic request module of the mixing in the Node B for each carrier wave, guarantee simultaneously to satisfy condition:, use the HARQ process of using when transmitting this PDU for the first time for the high-speed downlink grouped data that retransmits; For the high-speed downlink grouped data of new generation, select idle HARQ process; Different carrier uses different HARQ processes.By on control channel, carrying the HARQ process of the current use of carrier wave ID and process ID notice UE, high-speed downlink grouped data can be sent to corresponding HARQ process and handle thereby make end side mix automatic repeat requests module, thereby realize of the support of HSDPA system multicarrier.
In order to make those skilled in the art person understand the present invention program better, the present invention is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 3, Fig. 3 shows the realization flow of the inventive method, may further comprise the steps:
Step 301:Node B is redefined for each UE and sends the HARQ process sum that high-speed downlink grouped data allows use.
Step 302: all carrier waves that send high-speed downlink grouped data for each UE are shared HARQ process transmission high-speed downlink grouped data.
Such as, to the UE that is scheduled, being made as it and having set up M HARQ process, this M process is shared by all carrier waves, and establishing the idle constantly HARQ process of t is E (t), E (t)=M when initial.
Support 8 HARQ processes in the existing standard at most, when a plurality of carrier waves are shared the HARQ process, possibly can't guarantee continuous scheduling.Therefore need make amendment to existing standard,, be used to represent more HARQ process ID by on control channel, increasing indication bit.
Because high-speed downlink grouped data unit of each carrier transmission, a plurality of carrier waves are shared M HARQ process, and when therefore distributing the carrier wave of transmitting high speed down grouped data for UE, the carrier number of selection can not surpass the process of current free time and count E (t).
The process that all carrier waves that each UE uses are shared HARQ process transmission high-speed downlink grouped data will be described in detail later.
Step 303: carrier wave ID and HARQ process ID that notice UE high-speed downlink grouped data uses.
Such as, can notify UE carrier wave ID and HARQ process ID that each high-speed downlink grouped data uses by control channel, simultaneously, also needing to notify this high-speed downlink grouped data of UE is the high-speed downlink grouped data of re-transmission or new high-speed downlink grouped data.
Step 304: terminal is handled the HARQ process that the high-speed downlink grouped data of receiving is submitted to correspondence according to carrier wave ID and HARQ process ID, obtains the business datum that needs.
With reference to Fig. 4, Fig. 4 shows the flow process of the shared HARQ process transmission of all carrier waves data in the inventive method, may further comprise the steps:
Step 401: obtain the current idle HARQ process number E (t) of the UE that is scheduled.
Step 402: the high-speed downlink grouped data that determine the to be scheduled current operable carrier wave of UE and each carrier wave need transmit.
At first, the current operable carrier wave of the UE that determines to be scheduled, and time slot that uses on each carrier wave and code channel resource are constructed the high-speed downlink grouped data of each carrier transmission then.
The front is mentioned, because high-speed downlink grouped data unit of each carrier transmission, a plurality of carrier waves are shared M HARQ process, and when therefore distributing the carrier wave of transmitting high speed down grouped data for UE, the carrier number of selection can not surpass the process of current free time and count E (t).
When the structure high-speed downlink grouped data, the soft buffer memory ability of the UE that reports in the time of inserting according to UE makes the soft buffer memory of the HARQ process of UE side correspondence can store this high-speed downlink grouped data through the data after the CRC check.
Step 403: the mixing different for each allocation of carriers retransmit the HARQ process automatically, and determine the HARQ process ID of each carrier wave ID and distribution.
In order to guarantee the correct transmission of downlink grouped data, when being each allocation of carriers appropriate H ARQ process, need satisfy following condition:
(1) if the high-speed downlink grouped data that retransmits uses the HARQ process of using when transmitting this high-speed downlink grouped data for the first time;
(2) if the new high-speed downlink grouped data that produces is then selected idle HARQ process;
(3) different carrier uses different HARQ processes.
Step 404: the idle HARQ process number that the described UE that is scheduled of real-time update is current.
Under following situation, need to upgrade the current idle HARQ process number of UE of being scheduled:
(1) N the new high-speed downlink grouped data unit of having established current scheduling is because each high-speed downlink grouped data unit will start a new process, so the value of E (t) is subtracted N; For the high-speed downlink grouped data unit that retransmits, then E (t) does not upgrade;
(2) if certain HARQ process has been received the ACK information of terminal feedback, show that the high-speed downlink grouped data unit is correctly received, then E (t) adds 1.If nack message, then E (t) is constant;
(3) if certain high-speed downlink grouped data unit has reached maximum retransmission and has been dropped, the HARQ process of its use also will be recovered so, and the value of E (t) adds 1.
Step 405: on the HARQ process of distributing described high-speed downlink grouped data is being sent on the corresponding carrier wave.
In actual applications, step 404 also can be carried out before step 402, such as, above-mentioned three kinds of situations are provided with corresponding marker bit and corresponding updating value respectively, before the structure high-speed downlink grouped data, check each flag bit and upgrade accordingly.
Certainly, also the UE that is scheduled can be counted E (t) at t idle process constantly and be set to a global variable, when above-mentioned three kinds of situations occurring, this variable be upgraded operation accordingly, realize real-time update the current idle process number of the UE that is scheduled.
As seen, utilize the inventive method, not only realized the transmission of multi-carrier HSDPA data, and the shared a certain number of HARQ process of all carrier waves of UE, reduce the complexity of HARQ management of process, and improved the flexibility that retransmits.
Further describe the processing procedure of multi-carrier HSDPA data in the base station below with reference to the MAC-hs model of UTRAN side shown in Figure 1.
Fig. 5 shows its transfer process, may further comprise the steps:
Step 501: initialization.
The UE that obtains setting allows the HARQ process of use to count M, and the value that UE is counted E (t) at t idle process constantly is made as M.
Step 502:RNC (radio network controller) is delivered to high level data the MAC-hs buffering area of Node B.
Step 503: the scheduler module current operable carrier wave of UE of determining to be scheduled, and time slot that uses on each carrier wave and code channel resource, and construct the MAC-hs PDU of each carrier transmission.
Because MAC-hs PDU of each carrier transmission, a plurality of carrier waves are shared M HARQ process, and when therefore distributing the carrier wave of transmitting high speed down grouped data for UE, the carrier number of selection can not surpass the process of current free time and count E (t).
Step 504: scheduler module is delivered to the HARQ entity with the MAC-hs PDU of current transmission, also will notify the HARQ entity simultaneously, and each MAC-hs PDU transmits on which carrier wave respectively.
Step 505:HARQ entity is responsible for each carrier wave and selects appropriate H ARQ process.
Step 506:HARQ module is upgraded the value of E (t).Update method is as follows:
If current scheduling N new MAC-hs PDU because each PDU will start a new process, so the value of E (t) is subtracted N; For the MAC-hs PDU that retransmits, then E (t) does not upgrade;
If certain HARQ process has been received the ACK information of terminal feedback, show that MAC-hs PDU is correctly received, then E (t) adds 1.If nack message, then E (t) is constant;
If certain MAC-hs PDU has reached maximum retransmission, the HARQ process of its use also will be recovered so, and the value of E (t) adds 1.
Step 507:HARQ module is delivered to bottom with the carrier wave ID and the HARQ process ID information of MAC-hs PDU and each PDU use.
Step 508: the bottom module is responsible for each MAC-hs PDU is sent on the carrier wave of appointment, and notifies terminal carrier wave ID and HARQ process ID that each PDU uses by control channel, and is to retransmit or new MAC-hs PDU.
Further describe the processing procedure of multi-carrier HSDPA data in the terminal below with reference to the MAC-hs model of end side shown in Figure 2.
Fig. 6 shows its transfer process, may further comprise the steps:
Step 601: the bottom module is delivered to the HARQ module with the MAC-hs PDU that receives and HARQ process ID, the carrier wave ID of current use.
Step 602:HARQ module sends to corresponding HARQ process with MAC-hs PDU and handles according to HARQ process ID, carrier wave ID.
Step 603:HARQ process judges whether MAC-hs PDU is correctly received, if then go to step 604, otherwise go to step 608.
Step 604: produce ACK, and feed back to Node B by control channel.
Step 605: MAC-hs PDU is submitted to rearrangement and disassembles module.
Step 606: reset and disassemble header and filling information among the module removal MAC-hs PDU, the data delivery after will handling then is to high-rise module.
Step 607: high-rise module is done further processing to data, obtains the business datum of final needs.
Step 608: judge whether MAC-hs PDU is to retransmit MAC-hs PDU.If then go to step 609, otherwise go to step 613.
Step 609: the data in MAC-hs PDU and the soft buffer memory are merged.
Step 610: judge whether the data after merging are correct, if, go to step 604, if not, go to step 611.
Step 611: the data after will merging are kept at the soft buffer memory of this HARQ process.
Step 612: produce NACK, and feed back to Node B by control channel.
Step 613: the data that will make mistakes are kept at the soft buffer memory of this HARQ process.
As seen, utilize the inventive method, all carrier waves that each UE uses are shared all HARQ processes that this UE allows use, have realized the transmission of multi-carrier HSDPA data simply and flexibly.
Though described the present invention by embodiment, those of ordinary skills know, the present invention has many distortion and variation and do not break away from spirit of the present invention, wish that appended claim comprises these distortion and variation and do not break away from spirit of the present invention.
