Feature of the present invention can join in the integrated circuit (IC), perhaps can be configured in the circuit that comprises a plurality of interconnecting members.
Different antenna space wave beam or channelization code can experience different channel qualities, and described channel quality can be fed back by CQI to be represented.Identical adaptive modulation and coding (AMC) can be used for all subcarriers, spatial beams or channelization code, and they are to have the independently quality of subcarrier, spatial beams or channelization code respectively.Replacedly, channel condition can be used to different AMC are used for different subcarriers, spatial beams or channelization code, with the maximization performance.
When use depended on the AMC of subcarrier, spatial beams or channelization code, according to the present invention, each data block of distributing to each subcarrier, spatial beams or channelization code was related with a CRC.Otherwise, when error of transmission,, need be retransmitted so be assigned to the whole group of different subcarriers, spatial beams or channelization code because whole group is related with single CRC.To waste valuable Radio Resource for the re-transmission of each data block that has correctly received.Because each antenna can be in different channel conditions, so when using MIMO, adopt identical condition.Therefore, according to the present invention,, independent CRC is added into each transmission data block when handling by each H-ARQ when using multidimensional H-ARQ to handle with one or more subcarriers, channelization code, transmitting antenna (or spatial beams) response.In traditional independent H-ARQ scheme, once only activate a H-ARQ and handle, and in each TTI, need to determine the only TFC of a transmission data block.Tradition TFC selection course does not have selects function with the QoS demand of suitable support high level data stream to being used for the TFC more than a data block that many H-ARQ handle.
Fig. 1 is that many H-ARQ used according to the invention handle the block diagram that sends the equipment 100 of many transmission blocks (TB) in Transmission Time Interval (TTI) simultaneously.This equipment 100 can be WTRU, Node-B or any other communicator.This equipment 100 comprises that a plurality of H-ARQ handle 102a-102n, a plurality of multiplexed and link adaptation processor 104a-104n and controller 106.Each is multiplexed related with link adaptation processor 104a-104n and a H-ARQ processing 102a-102n.Each multiplexed and link adaptation processor 104a-104n receive physical resource configuration (being that subcarrier is distributed or centralized, a MIMO antenna configurations etc.) and the CQI related with these physical resources.
It is related with the particular group physical resource that each available H-ARQ handles 102a-102n.Dynamically definite physical resource is handled the related of 102a-102n with H-ARQ, perhaps can dispose this association semi-staticly.Network entity (for example eNB scheduler) determines to distribute how many physical resources.When selecting TFC by multiplexed and link adaptation processor 104a-104n at every turn, when perhaps each this H-ARQ handles 102a-102n and produces H-ARQ for specific T B and retransmit, but dynamic reallocation and the related physical resource of specific H-ARQ processing.Can carry out the reallocation of physical resource based on the CQI of specific physical resource, perhaps can determine the reallocation of physical resource based on predetermined frequency-hopping mode.
Multiplexed and link adaptation processor 104a-104n handle 102a-102n for every group of physical resource with related H-ARQ and independently carry out link adaptation.Each multiplexed and link adaptation processor 104a-104n determines the maximum times of modulation and encoding scheme (MCS), multiplexed TB, transmitted power demand, H-ARQ redundancy versions and each TTI re-transmission.This group transmission information is offered each H-ARQ handle 102a-102n.
Can flow (if implementing MIMO), the independent subcarrier in frequency domain (if implementing OFDMA or FDMA), the independent channel coding in encoding domain (if implementing CDMA), the independent time slot in time domain or above-mentioned combination in any by the separate space in spatial domain and define physical resource.Independently subcarrier can be distributed or centralized.Channelization code is to distribute to the physical resource of different TB independently.In cdma system, can distribute different channelization code, to send a TB or several TB based on each TB required channel condition and data rate.The maximum quantity of the TB that can send is less than or equal to the maximum quantity of available channelization code.But, can use several H-ARQ to handle and send several TB simultaneously via different physical resources when several separate spatial flow, subcarrier or channelization code time spent.For example, if two spatial flows are available in 2 * 2MIMO system, then can use two independent H-ARQ to handle and send two TB simultaneously via two spatial flows.
Different physical resource (being different subcarrier, antenna space wave beam, channelization code or time slots) can experience different channel qualities.Determine the quality of each physical resource by one or more CQI measurements.CQI can feed back from communication counterpart, perhaps can obtain based on the channel reciprocity.Also can represent CQI by the MCS and/or the maximum transport block size of permission.
Available physical resources is the amount that is used for independently spatial flow, subcarrier, channelization code and the time slot of transfer of data in can be during certain.Available physical resources for a WTRU depends on a plurality of factors, for example the quantity of the Node-B WTRU that need support in a sub-district, the data rate that need support from the QoS level (for example priority, potentiality, fairness and buffering state) of the channel condition of the interference level of other sub-district, WTRU, service that WTRU need support, WTRU etc.
According to the present invention, many H-ARQ handle 102a-102n and move simultaneously and concurrently.102a-102n can be in order successfully to transmit the re-transmission of adopting varying number owing to the H-ARQ processing, and owing to the data flow that maps to H-ARQ processing 102a-102n can have the definite varying number that retransmits or the QoS demand of different TTI size, if differ from one another the step so H-ARQ handles, then certain H-ARQ may be disabled.In arbitrary TTI, the H-ARQ of any amount processing can become available.According to the present invention, in common TTI, become available with one group of related physical resource more than a H-ARQ processing.By controller 106 coordinate H-ARQ handle and physical resource between association.
Replacedly; also can by based on data flow QoS demand with distribute to the related CQI of physical resource group that each H-ARQ handles, the high level data stream 108a-108m that will can divide into groups according to the QoS demand and different H-ARQ processing 102a-102n shine upon and realize the error protection that do not wait.For example, CQI can illustrate one group of physical resource be better than other the group physical resource.High level data stream with higher QoS demand can map to and the better related H-ARQ processing of physical resource.The QoS demand, grouping size, the H-ARQ capacity that flow based on high level data wait definite quantity that will map to the high level data stream of specific H-ARQ processing.In case determine to use specific H-ARQ to handle each high level data stream of transmission, come multiplexed these data flow by the multiplexed and link adaptation processor 104a-104n that is used for different H-ARQ processing.
Each multiplexed and link adaptation processor 104a-104n receives input (for example the buffer capacity of the CQI of the physical resource of Fen Peiing, maps data streams etc.), and definite physical transfer parameter and H-ARQ configuration, to support to handle the QoS demand of the high level data stream 108a-108m of mapping with each H-ARQ.Described physical transfer parameter comprises: through-put power, modulation and encoding scheme, TTI size, transmission block size and wave beam form pattern, sub-carrier allocation, MIMO antenna configurations etc.The H-ARQ configuration parameter comprises: H-ARQ sign, the maximum times that retransmits, redundancy versions (RV), CRC size etc.Multiplexed and link adaptation processor 104a-104n offer related H-ARQ with the H-ARQ parameter and handle 102a-102n.
Multiplexed all physical resources that can adopt identical MCS, transmission block size, TTI size and/or transmitted power to have nothing to do to quality with physical resource with link adaptation processor 104a-104n.Replacedly, multiplexed and link adaptation processor 104a-104n can adopt different MCS, transmission block size, TTI size and/or based on the channel condition transmitted power to different physical resources, so that maximizing performance.
When AMC that uses the dependence physical resource and H-ARQ operation, preferably, that each data block of distributing to each physical resource is related with single CRC.By this scheme, the whole group that is distributed to different physical resources does not need to be retransmitted when error of transmission, because each transmission block is related with single CRC, and handles 102a-102n by single H-ARQ and handles.
Then, multiplexed and link adaptation processor 104a-104n is selecting suitable TFC (be that TB size, TB group size, TTI are big or small, modulation and encoding scheme (MCS), through-put power, antenna beam, sub-carrier allocation, CRC size, redundancy versions (RV) and map to the data block etc. of Radio Resource) the high level data stream 112a-112m generation TB from distributing afterwards based on CQI and physical transfer parameter to TB.One or more high level data streams can be multiplexed into a TB.Single CRC is added into each TB, is used for independent error detection and H-ARQ and handles.Each TB is provided to the H-ARQ processing 102a-102n that distributes with related transmission parameter.Then, handle 102a-102n via the H-ARQ that distributes respectively and send TB.
Can use transmission or blind Detecting technology to decode before the transmission parameter the recipient, the parameter that can support many H-ARQ to handle transfer to the recipient with signal.The TB that produces along with being sent to H-ARQ, the transmission parameter of association is handled 102a-102n, to be used for transmission.
Fig. 2 is the flow chart that many H-ARQ used according to the invention handle the method 200 of transmitting many TB in TTI simultaneously.The identification available physical resources with handle the channel quality (step 202) of the related available physical resources of 102a-102n with each H-ARQ.Determine QoS demand and the buffering capacity (step 204) of high level data stream 112a-112m to be sent.It should be noted that the step in method 200 can be carried out with different orders, some step available parallelisms are carried out.For example, step 204 can be used on before the step 202 or synchronously and carries out.
By controller 106 high level data is flowed 112a-112m and map to each H-ARQ processing 102a-102n.Handle 102a-102n for each available H-ARQ and determine physical transfer parameter and H-ARQ configuration, to support to map to the required QoS (step 206) that each H-ARQ handles the high level data stream 112a-112m of 102a-102n.But, be necessary to determine which high level data stream 112a-112m is mapped to different H-ARQ handles when in TTI, having more than a H-ARQ processing time spent for transmission.High level data stream 112a-112m can have or not have similar QoS demand.
When the subclass that flows 112a-112m to all high level datas stream 112a-112m or the high level data of different H-ARQ processing to be mapped needs similar QoS, standardize (promptly in each TTI for the QoS that provides by H-ARQ processing 102a-102n then, regulate transmission parameter (for example MCS, TB size and through-put power) and H-ARQ configuration, selecting TFC, is similar thereby handle the QoS that provides among the 102a-102n at H-ARQ).The QoS that can be implemented between many H-ARQ processing 102a-102n by the link adaptation parameters (for example MCS, TB size, through-put power etc.) that is adjusted between a plurality of H-ARQ processing 102a-102n standardizes.For example, available higher MCS is distributed to the physical resource with better channel quality, and will distribute to physical resource than low MCS with poor channel quality.This can cause the multiplexed data blocks for the different sizes of different H-ARQ processing.
Replacedly, when high level data stream 112a-112m needs different QoS, high level data stream 112a-112m can be mapped to the H-ARQ related with physical resource and handle 102a-102n, and wherein said physical resource has the quality near the QoS demand that is matched with high level data stream 112a-112m.The advantage of using many H-ARQ to handle is its flexibility to multiplexing logic channel or MAC stream, and wherein said MAC stream has the related physical resource of different QoS requirements handle 102a-102n and to(for) different H-ARQ.When certain physics resource representation channel quality was better than other physical resource, the data with higher QoS were mapped to the H-ARQ related with this physical resource and handle.This has improved the use of physical resource, and has maximized throughput of system.Replacedly, or additionally, the maximum times of configurable MCS and/or re-transmission is the QoS demand of matching logic channel or MAC stream closer with distinguishing QoS.
Map to after H-ARQ handles 102a-102n high level data being flowed 112a-112m, undertaken multiplexedly by handling the related high level data stream 112a-112m of 102a-102n, handle the physical transfer parameter of 102a-102n and H-ARQ and dispose to produce and be used for each H-ARQ and handle 102a-102n (step 208) according to being used for each H-ARQ respectively with each H-ARQ.But be used for data multiplex sequential processes or parallel processing that each H-ARQ handles 102a-102n.Then, the H-ARQ processing 102a-102n via association sends TB (step 210) simultaneously.
May or can not successfully receive the TB of transmission the communication party.In subsequent TTI, retransmit the TB of failure.Preferably, the size of the TB of re-transmission remains on the identical size that the communication party carries out soft merging.Re-transmission for the TB that fails has several selections.
Select according to first, retransmit the physical resource that distributes remain unchanged (promptly handling the TB that retransmits failure) via identical physical resource and H-ARQ for the H-ARQ of TB.Transmission parameter and H-ARQ configuration (being TFC) can be changed.Particularly, link adaptation parameters (for example day line options, AMC or transmitted power) can be changed, to maximize the chance that successfully transmits the TB that retransmits.When changing link adaptation parameters, the parameter that changes can be sent to the recipient with signal for the re-transmission of the TB that fails.Selectively, the recipient can adopt the blind Detecting technology, the signaling load of the parameter that is used to change with elimination.
Select according to second, the physical resource that distributes for the H-ARQ of transmission block retransmits can be by dynamically reallocation (promptly retransmitting the TB that fails) in different physical resources and identical H-ARQ processings.The reallocation of physical resource can be based on CQI or based on known frequency-hopping mode.
In another was selected, the H-ARQ of failure transmission can segmentation in many H-ARQ handle, and each independently segmentation send to increase the possibility of successful H-ARQ transmission.Select according to this, the physical resource that is used to retransmit TB is reallocated (promptly handling the TB that sends failure via different H-ARQ).Be used for H-ARQ that TTI formerly sends the TB of failure be treated as available, to be used at subsequent TTI transmission other TB arbitrarily.The quantity of maximum transmit power, subcarrier or channelization code, the quantity of antenna or distribution and recommendation MCS can be reallocated, with the re-transmission of the TB that is used to fail.Preferably, can produce the TFCS subclass of new permission, the physical resource of the TB that is used to fail with reflection changes.New argument can be sent to the recipient with signal, to guarantee successfully reception.Replacedly, can adopt the blind Detecting technology, the signaling load of the parameter that is used to change with elimination the recipient.
