Embodiment
In the embodiment of the present invention, consider when having configured semi-continuous scheduling, the business that originally was carried in non-scheduled transmission can be carried with the mode of semi-continuous scheduling fully, be also that semi-continuous scheduling can replace non-scheduled transmission fully, compare with the mode of non-scheduled transmission, the characteristics that the method for salary distribution of semi-continuous scheduling has flexibly, expense is little, configure having little significance of non-scheduled transmission when having configured the CPC transmitting uplink data, namely 4 of non-scheduled transmission processes may can not get effective utilization in this case again.
In addition, consider that again when having configured semi-continuous scheduling, network or terminal also may be upgraded, additionally increase corresponding process and support transmitting uplink data, so extra increase process can be applied to traditional scheduled transmission too, thereby makes all processes be utilized effectively.
therefore, not enough for the process sum that solves the system that has configured semi-continuous scheduling in prior art in the embodiment of the present invention, and the problem that can't fully effectively utilize of the process of non-scheduled transmission, consideration will originally be used for the association process collection of non-scheduled transmission and/or the association process collection of extra increase and the association process collection of scheduled transmission and merge, with the transmitting uplink data of the process in the process collection after merging for the system that has configured semi-continuous scheduling, be about to original process or extra process that increases that is used for non-scheduled transmission and be on loan to the CPC transmitting uplink data.Reaching increases the purpose that the UE transmitting uplink data can be used the process sum.
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with embodiment and accompanying drawing, the present invention is described in more detail.
Fig. 1 is the exemplary process diagram of the process scheduling method in embodiment of the present invention communication system.As shown in Figure 1, this flow process comprises the steps:
Step 101 starts the processing mode that the merging transmitting uplink data can be used process.
In this step, start merging transmitting uplink data can have with the method for the processing mode of process multiplely, for example can have:
(1) network side and UE when satisfying the trigger condition of setting, by indicating the value of design variables in self, determine whether to adopt the mode of operation of merging process, when determining to adopt the mode of operation of merging process, and execution in step 102; Otherwise, finish.
Wherein, network side (for example RNC of network side) and UE side have all defined indicator variable, as variable Process_Set_Untility_Indicator, this variable becomes True when satisfying certain trigger condition, and network side and UE adopt the processing mode of merging process simultaneously.Wherein, if network side has only defined indicator variable in RNC, when network side adopted the processing mode of merging process, the RNC of network side also needed informing base station to adopt and merges the processing mode of processing.
Wherein, described trigger condition can be: configure or started semi-continuous scheduling transmission, and not configuring non-scheduled transmission.
(2) network side notifies UE to start the processing mode of merging process by high-level signaling.
During specific implementation, the processing mode that can start merging process by RNC difference informing base station and the UE of network side.
(3) network side notifies UE to start the processing mode of merging process by control channel.
During specific implementation, can notify UE to start the processing mode of merging process by control channel by the base station of network side.Accordingly, can at first be started the processing mode of merging process by the RNC indication base station notice UE of network side.
In the present embodiment, if fixed configurations adopts the processing mode of merging process, step 101 can be omitted.The purpose that adopts step 101 be for the processing mode supported with existing HSUPA compatible mutually.
Step 102 merged originally being used for the association process collection of non-scheduled transmission and/or the association process collection of extra increase and the association process collection of scheduled transmission, obtained for the process collection after the merging of CPC transmitting uplink data.
In this step, support 4 processes (being CPC transmitting uplink data process used) and non-transfer transmission to support the situation of 4 processes for the transfer transmission of present HSUPA, if the process of non-scheduled transmission and the process of scheduled transmission are merged, comprise altogether 8 processes in the process collection after merging.Wherein, network side and UE side store respectively the information of each process.
Step 103 is chosen the process for the CPC transmitting uplink data from the process collection after described merging.
In the present embodiment, for the operation of performing step 103, multiple implementation can be arranged, the below for distinguishing process collection and not distinguishing the situation of process collection, is described in detail the present embodiment respectively.
Consider that UE is after choosing process, need to selected process be indicated to the base station by the process ID in E-UCCH, and all only support 4 processes due to scheduled transmission and non-scheduled transmission in present HSUPA system, therefore present process ID only represents with 2 bits, in order existing process ID not to be changed, process collection after can considering in the present embodiment to be combined is selected according to the mode of distinguishing process collection, and the process number in each process collection can not exceed the expression scope of existing process ID like this.When choosing the process of current the transmission of data, can at first choose an association process collection as goal set the process collection after merging, then choose the process for the CPC transmitting uplink data from goal set.During specific implementation, selected goal set and the process in goal set can be indicated respectively.For example, then the definite goal set that need choose of Node B indicates the goal set of determining to UE, UE chooses process from goal set after, still utilizes the process in the selected goal set of existing process ID indication.Perhaps, UE preferentially selects different process collection according to the corresponding relation of predefined business and process collection for different business, and namely UE according to the data of the different business of current transmission, selects the process in different process collection.Perhaps, also can be directly choose process in goal set and goal set by UE according to other principle, then utilize out of Memory or the extra indication information indicating target set that increases in the E-UCCH that temporarily transfers, and still utilize the process in the selected goal set of existing process ID indication.Perhaps, also other specific implementation can be arranged.
Based on above-mentioned analysis, the technical scheme of the differentiation process collection that proposes in the present embodiment can comprise following several at least:
Fig. 2 is a kind of implementation method schematic flow sheet when distinguishing process collection in the present embodiment.As shown in Figure 2, this flow process comprises the steps:
Step 201, the Node B of network side chooses an association process collection as goal set from the process collection after described merging, selected goal set is indicated to UE by control channel.
In this step, Node B can choose based on the mode that different business is preferentially chosen different process collection.For example, situation about merging for the association process collection with the association process collection of non-scheduled transmission and scheduled transmission, but the association process collection that predefine will be originally be used for non-scheduled transmission (for convenience of description, hereinafter to be referred as association process collection A) preferentially for E-AGCH Less operation, original association process collection (for convenience of description, hereinafter to be referred as association process collection B) that is used for scheduled transmission still is used for scheduled transmission.
Perhaps, Node B also can choose according to alternate manner, does not do restriction herein.
It is multiple that Node B indicates UE should use the mode of the process in which set to have by control channel, for example, and following several modes:
<1〉increase explicit indication information in control channel, utilize described indication information that selected goal set is indicated to UE.During specific implementation, Node B can be set to different values by indication information, indicates the process in UE use different sets.For example, for the situation of above-mentioned association process collection A and B, this indication information can be the indication of 1bits (bit), when the process in Node B notice UE use A, can be set to 1 by indication information; When notifying the process in UE use B, can be set to 0 by indication information.
After UE received described control channel, according to the different values of wherein said indication information, judgement should be adopted the process in which set.
<2〉NodeB utilizes the indicated different implications of information field on control channel, implicitly indicates different subsets.
For example, for above-mentioned association process collection A and B, when information field on control channel indicated be when distributing half-persistence scheduling resources in E-AGCH Less operation, can indicate association process collection A (can certainly indicate association process collection B), after UE receives described control channel, according to this indication, the process in A (or B) is all adopted in the transmission of carrying out on half-persistence scheduling resources.
When information field on control channel indicated be when distributing the resource of 1 TTI in E-AGCH Less operation, can indicate association process collection A (can certainly indicate association process collection B), UE uses the process in A to transmit after receiving described control channel.
When information field on control channel indicated be the control information of non-E-AGCH Less operation the time, indicate association process collection B (can certainly indicate association process collection A), UE uses the process in B to transmit after receiving described control channel.
<3〉utilize the different association process collection of different-format indication of control channel, be about to the binding of association process collection and control channel form.
Can will shine upon between different control channel forms and association process collection in advance, NodeB wishes UE uses the process in which set, just utilize the control channel of corresponding format to send control information to UE, wherein, different control channel forms can represent by the information of the different bit numbers that carry on control channel.
<4〉utilize the cyclic redundancy check (CRC) code (CRC) of control channel and by the bit reversal code, selected goal set is indicated to UE.
For example, be used for CRC indication association process collection A, that utilizes CRC indicates association process collection B by the bit reversal code.
Step 202, UE chooses the process for the CPC transmitting uplink data according to the indication of described base station from described goal set.And UE utilizes the process ID in E-UCCH that the process in selected goal set is indicated the B to Node.
Fig. 3 is another the implementation method schematic flow sheet when distinguishing process collection in the present embodiment.In this flow process, the main predefine mode that adopts is selected, and as shown in Figure 3, this flow process comprises the steps:
Step 301 pre-determines the association process collection that each type of service is preferentially selected, and by the RNC of network side, the corresponding relation of determined type of service and association process collection is notified to UE and Node B by high-level signaling respectively.
for example, suppose that current CPC transmitting uplink data comprises the transfer of data of VoIP business and the transfer of data of other HSUPA business, the process collection (as the aforementioned process set B) of the preferential process collection (as the aforementioned process set A) of using and preferential use when carrying out the transfer of data of other HSUPA business in the time of can determining to carry out the transfer of data of VoIP business, indicated to UE and Node B (perhaps directly configuring to UE and NodeB) by high-level signaling respectively by RNC afterwards, the preferential process collection A that uses when carrying out the transfer of data of VoIP business, the preferential process collection B that uses when carrying out the transfer of data of other HSUPA business.
Perhaps, in this step, RNC also can be according to the corresponding relation of predetermined type of service and process collection, configuration UE and NodeB.
Perhaps, the corresponding relation of each type of service of predefine and association process collection, UE and NodeB select according to this predefined corresponding relation.
Step 302, UE is according to corresponding relation and the current business of carrying out the CPC transmitting uplink data of described type of service and association process collection, choose an association process collection as goal set from the process collection after described merging, choose the process for the CPC transmitting uplink data from described goal set.
For example, suppose that current CPC upstream data is the VoIP business datum, UE can choose a process from process collection A.
Step 303, UE indicates the B to Node with selected process.
Wherein, UE utilizes the idle bit in out of Memory on E-UCCH, or utilize the implication of out of Memory, or utilize the extra bit that increases to the selected process collection of Node B indication, utilize the process ID in E-UCCH that the process in selected process collection is indicated the B to Node.
For example: UE can utilize the selected goal set (for example, TBS Index represents when being strange to represent process collection B during for idol by process collection A) of parity indication of TBS Index (transport block size index) information in E-UCCH; Perhaps, UE can reduce the bit number of the TBS Index information in E-UCCH, utilizes the vacant selected goal set of bit number indication that goes out; Or UE can increase indication information in E-UCCH, utilizes the selected goal set of this indication information indication.
Afterwards, when Node B receives upstream data, parse the selected process of UE.
Fig. 4 is another the implementation method schematic flow sheet when distinguishing process collection in the present embodiment.As shown in Figure 4, this flow process comprises the steps:
Step 401 is chosen an association process collection as goal set the process collection of UE after merging, and chooses the process for the CPC transmitting uplink data from described goal set.
In the present embodiment, the process collection of making decisions on one's own and will choose by UE.
Step 402, UE indicates the B to Node with selected process.
In this step, concrete indicating mode can have multiple equally, for example comprises at least following several:
The first: the process subset that this mode is only applicable to divide is the situation of two, as aforementioned process set A and process collection B.In this mode, UE (for example can utilize the selected goal set of the parity indication of TBS Index (transport block size index) information in E-UCCH, TBS Index represents process collection A when being strange, represent process collection B during for idol), utilize process ID in E-UCCH to indicate process in this goal set.
The second: it is two that this mode is not limited to process collection, but two or more.In this mode, UE can reduce the bit number of the TBS Index information in E-UCCH, utilizes the vacant selected goal set of bit number indication that goes out, and utilizes process ID in E-UCCH to indicate process in this goal set.
The third: in this mode, UE can be according to actual needs increases some bits in E-UCCH indication information (for example, only has the situation of two for process collection, can increase the indication information of 1 bit), utilize the selected goal set of this indication information indication, utilize process ID in E-UCCH to indicate process in this goal set.
Certainly, during specific implementation, based on practical application scene or different considerations, above-mentioned Fig. 2 also is not limited to the restriction that the process number in each process collection does not exceed the expression scope of existing process ID to the mode of differentiation process collection shown in Figure 4.At this moment, in order to represent the concrete process in selected process collection, UE can be to the expansion of the process ID process in E-UCCH, and concrete expansion can be: temporarily transfer idle bit from out of Memory; Or utilize the implication of out of Memory and process ID jointly to represent; Or directly increase bit number of process ID etc.
In addition, if do not consider to distinguish process collection, the implementation of not distinguishing process collection shown in following can be arranged.
In this mode, can be with all the process Unified numbers in the process collection after merging, UE directly chooses a process that is used for the CPC upstream data from the process collection after described merging, then selected process is indicated to Node B on the E-UCCH channel.Wherein, concrete indicating mode can have multiple, for example, can temporarily transfer idle bit with the bit number of expansion process ID from out of Memory; Or utilize the implication of out of Memory and process ID jointly to represent; Or directly increase the bit number of process ID.The below enumerates wherein dual mode:
Mode one: UE reduces the bit number of the TBS Index information in E-UCCH, as reducing 1bit, utilizes the length of the vacant former process ID of bit number expansion that goes out, and utilizes the selected process of process ID indication after expansion.
Mode two: UE utilizes the information of parity indication 1 bit of the TBS Index information in E-UCCH, for example TBS Index is that odd number represents that this bit is 0, TBS Index is that even number represents that this bit is 1, afterwards the information of this 1 bit and former process ID territory is combined the selected process of indication.
According to the description of above-mentioned process scheduling method, the process scheduling system in the embodiment of the present invention mainly comprises network equipment and the UE that uses above-mentioned process scheduling method.Wherein, network equipment mainly comprises RNC and Node B.
