Background technology
Existing HSDPA (High Speed Downlink Packet Access, the high speed downlink packet access) in the technology, HS-SCCH (High Speed shared control channel, High-Speed Shared Control Channel) is used to carry HS-PDSCH (High Speed Physical Downlink Shared Channel, the high-speed downstream Physical Shared Channel) scheduling and control information, Fig. 1 is the control procedure schematic diagram of HSDPA shared channel timing relationship and HS-SCCH, as shown in Figure 1, after downlink data arrives through scheduling, Node B (base station) sends Downlink Control Information at HS-SCCH earlier, indicate UE (User Equipment is arranged on the follow-up HS-PDSCH, subscriber equipment) downlink data, UE need continue to monitor to the one group HS-SCCH of network side for its configuration, behind correct deciphering HS-SCCH, the HS-PDSCH that receives its indication goes up the downlink data of carrying, corresponding according to the decoded result utilization again HS-SICH (SharedInformation Channel for HS-DSCH, the shared information channel of HS-DSCH with HS-SCCH; HS-DSCH:High Speed Downlink Shared Channel, high speed descending sharing channel) feeding back ACK/NACK (affirmation/non-affirmation) information.
Because follow-up HSPA+ (High Speed Packet Access Plus high-speed packet inserts and strengthens) is in order to support CPC (Continuous Packet Connectivity, continuing grouping connects) and MIMO (MultipleInput Multiple Output, multiple-input and multiple-output) function has defined 9 kinds of HS-SCCH forms altogether.Here the HS-SCCH type1 (Class1) with traditional HSDPA Release 5 (version 5) is an example, and its loaded information is as shown in the table:
Abbreviation implication in the table is:
TFRI:Transport Format Resource Indicator, the transport format resource indication;
HARQ:Hybrid Automatic Repeat Request, mixed automatic repeat request;
HCSN:HS-SCCH cyclic sequence number, HS-SCCH cyclic sequence number;
SS:Synchronization Shift, the synch command word;
TPC:Transmit Power Control, the transmission power control command word;
QPSK:Quaternary Phase Shift Keying, quadriphase PSK;
QAM:Quadrature Amplitude Modulation, quadrature amplitude modulation;
BLER:BLock Error Rate, Block Error Rate;
CRC:Cyclic Redundancy Check, cyclic redundancy check (CRC).
As can be seen from the table, the indicated gap information of HS-SCCH Type1 has 5 bits, can only indicate time slot (TS, Time Slot) 2 to time slot 6 at present, and time slot 0 can not be as the HS-PDSCH resource.Other 8 kinds of HS-SCCH of protocol definition also adopt identical method indication gap information at present, promptly can only indicate time slot 2 to time slot 6, can't indicate time slot 0.The code channel assignment information is to indicate by CCS (Channelisation code set, channel code set information) in addition, and CCS has provided initial code channel and stopped code channel information.Agreement stipulates that all time slots use identical channel code set information at present.
Existing TD-SCDMA (Time Division-Synchronous Code Division MultipleAccess, the CDMA (Code Division Multiple Access) that time-division is synchronous) in the system N frequency point cell, owing to consider and disturb and power problem, common signal channel all is configured in main carrier, the time slot of auxilliary carrier wave, code channel resource generally do not use except configuration FPACH (Fast Physical Access Channel, physical access channel).Along with the lifting of number of users in the network and the lifting of data service use amount and demand, need to consider to increase the sector-carrier number.After introducing F-band, can consider the use of auxilliary carrier wave TS0 resource.A kind of may be the resource bearing HS-PDSCH of TS0, and if HS-PDSCH is carried on TS0, need its control channel HS-SCCH indication TS0 time slot and code channel resource.Agreement stipulates that all time slots use identical channel code set information at present in addition.Yet, because the TS0 resource may be used as other channel resource, DPCH (Dedicated Physical Channel for example, DPCH) etc., the surplus resources of TS0 time slot may not be full code channel resource when being used as the HS-PDSCH resource, or discrete code channel resource, so when TS0 dispatches as HS-PSDCH, if use identical code channel resource indication with other time slot, then may cause resource not make full use of.
As mentioned above, the deficiencies in the prior art are: because the lifting of user's request at present and business demand, need to use TS0 resource bearing HS-PDSCH, and the time interval resource that can only indicate TS2 to TS6 on the control channel HS-SCCH of present HS-PDSCH can't be indicated TS0.In addition, the resource of TS0 is because other channel of carrying, and when carrying during HS-PDSCH, resource is non-full code channel resource or discontinuous code channel resource, causes when other descending time slot is dispatched, and resource can not make full use of.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
Fig. 2 is a resource indicating method implementing procedure schematic diagram, as shown in the figure, can comprise the steps: when carrying out the resource indication
Step 201, RNC (Radio Network Controller, radio network controller) are time interval resource and the code channel resource of base station assigns HS-PDSCH;
Step 202, RNC notify time interval resource and the code channel resource of UE HS-PDSCH by high-level signaling;
With the scheduled resources indication notice UE of base station institute, described resource indication comprises the information-based sign indicating number information indication of time slot indication and indication code channel by HS-SCCH for step 203, base station;
Step 204, UE determine to receive the resource location of HS-PDSCH data according to described resource indication.
In the enforcement, RNC is that the HS-PDSCH resource pool is distributed in base station (Node B); The resource of the time slot that can be dispatched by system broadcast message for example or RRC (Radio Resource Control, Radio Resource control) signaling contour level signaling UE of high level then; The base station is notified to UE by downlink physical control channel HS-SCCH with institute's scheduled resources again; Thereby make UE on indicated resource, to receive the HS-PDSCH data by decoding HS-SCCH.
Concrete, in step 201, RNC comprises time interval resource and code channel resource (channelization code information) for Node B distributes the HS-PDSCH resource pool in the resource pool.Wherein, code channel resource and channelization code information are actual is a meaning.How many code channels code channel resource has distributed in other words, has just distributed which channel code, wherein code channel of each channel code sign.
In step 202, high-level signaling can comprise: system broadcast message and/or dedicated signaling.High-rise resource by system broadcast message or dedicated signaling notice UE institute time slot scheduling can comprise time interval resource and code channel resource (channelization code information).
In step 203, the base station is by HS-SCCH indication institute scheduled resources, and this resource can comprise: time slot indication and channelization code information indication; The time slot indication can comprise indication time slot TS0.
In concrete the enforcement, when time slot is indicated by HS-SCCH in the base station, can comprise:
1, use 1 bit specific bit or reserved bit to indicate the time slot of being dispatched;
Or, 2, use the channel code initial code to indicate the time slot of being dispatched greater than stop code.
The time slot indication can come explicit indication or implicit expression indication by control bit on HS-SCCH.For example:
Under the 1st kind explicit indicating mode: use 1 bit specific bit or reserved bit to indicate the time slot of being dispatched.
Under the 2nd kind implicit expression indicating mode: use the channel code initial code to indicate the time slot of being dispatched greater than stop code.For example, stipulate that initial code is smaller or equal to stop code among the HS-SCCH Type1 at present.Can use initial code to represent the time slot of being dispatched (for example TS0) greater than stop code so.
In the enforcement, when first kind of explicit indication, 1 bit specific bit can be 1 bit of CCS, perhaps 1 bit of TS.
1 bit specific bit of explicit indication can be meant: can use certain bit for regulation, or present untapped reserved bit, or already used bit.For example: indicate such as a bit that can use CCS, then present CCS is because indication bit reduces, and then the code channel partition size becomes big.Perhaps, for example: can the high-rise implication of revising present 5 bit TS, take out wherein 1 bit as the time slot indication of being dispatched, for example, present 5 bits are represented TS2 to TS6, first bit can be indicated as scheduling TS 0, and other 4 bit is as the indication of TS3 to TS6.
In the enforcement, under the 2nd kind implicit expression indicating mode, use the channel code indication can comprise following mode:
1), all time slots use identical channelization code information.For example: promptly TS0 uses identical channelization code information with TS2 to TS6, and channelization code information is still used the CCS indication, and this mode benefit do not need to be control channel additionally to indicate;
Perhaps, 2), the channel code of institute's time slot scheduling uses the channelization code information of institute's time slot scheduling of high-rise configuration.Under this mode, implicit expression is indicated the channel code of time slot scheduling separately, promptly uses the channelization code information of institute's time slot scheduling of high-rise configuration, and the channelization code information of other time slot is still used the CCS indication, and the benefit of this mode do not need to be control channel additionally to indicate;
Perhaps, 3), 1 bit specific bit or reserved bit indicate the channelization code information of institute's time slot scheduling to be to use the channelization code information of high-rise configuration also to be to use the channelization code information of the CCS indication identical with other time slot on the channel code of the institute's time slot scheduling use control channel.Under this mode, the channel code of independent explicit indication institute time slot scheduling promptly uses on the control channel 1 bit specific bit or reserved bit to indicate the channelization code information of institute's time slot scheduling to be to use the channelization code information (for example this bit is set to 0 expression) of high-rise configuration also to be to use the channelization code information (for example this bit is set to 1 expression) of the CCS indication identical with other time slot.Channelization code information can be passed through system broadcasts or RRC signaling UE in the enforcement.
In the enforcement, after UE determines to receive the resource location of HS-PDSCH data according to described resource indication, can further include:
UE receives the HS-PDSCH data according to predefined mapping relations and high-rise being configured on definite resource location.
Terminal can also receive the HS-PDSCH data then by decoding HS-SCCH in force on indicated resource, in the enforcement, terminal can receive the HS-PSDCH data according to predefined mapping relations and high-rise configuration on respective resources.Respective resources can comprise indicated time interval resource and channelization code resource.Employed time interval resource and channelization code resource are corresponding with the indication of base station side.
Be that example describes below with the scheduling TS 0.
Be that example describes with TS0 in the present embodiment, but, when implementing by the mode of this programme, other TS can dispatch too, TS0 only is used to instruct those skilled in the art specifically how to implement the present invention, but do not mean and only can use TS0, can need dispatch corresponding TS in conjunction with practice in the implementation process, promptly pressing such scheme also can be as the resource allocation indication of other time slot after expansion.
When TS0 is indicated, at first, RNC can comprise the available time slot resource, available code channel resource etc. by physics Physical Shared Channel reconfiguration request (PHYSICAL SHARED CHANNEL RECONFIGURATION REQUEST) message for Node B distributes the HS-PDSCH resource pool.For example comprise that TS0 time slot and TS0 can use code channel resource (can be full code channel resource, also can also can be discontinuous code channel resource for non-full code channel resource).
Then, RNC can comprise that TS0 time slot and TS0 thereof can use code channel resource by the resource of system broadcast message or RRC signaling UE institute time slot scheduling.
Afterwards, UE can be given with the resource notification of TS0 by HS-SCCH in the base station, and concrete indicating mode can use any one in the following mode.
At last, terminal is decoded to HS-SCCH according to preset mapping relation and high-rise configuration thereof, obtains the resource of available TS0, and receive the HS-PDSCH data on this resource.
Concrete, the base station is when giving UE by HS-SCCH with the resource notification of TS0, and the indicating mode of TS0 time slot can be as follows:
Mode 1, RNC are the resource (time interval resource and channelization code resource) of Node B distribution T S0, and network side indicates the use of representing the TS0 time slot by special time slot, can realize by revising the mapping relations that HS-SCCH goes up TS.For example TS is made up of 5 bits at present, indicate TS2~TS6 whether to dispose HS-PDSCH respectively, can indicate certain bit in this 5 bit TS signaling to be used to refer to TS0 by 3 bits in this mode signaling on the middle and senior level so, do not dispose HS-PDSCH as first time slot TS2 among 001 expression TS2~TS6, promptly first bit is used to refer to TS0 in 5 bits of TS; The 2nd time slot TS3 among 010 expression TS2~TS6 do not dispose HS-PDSCH, and promptly the 2nd bit is used to refer to TS0 in 5 bits of TS; The rest may be inferred.In addition, network side can also be represented the use of TS0 time slot by 5 bit high-level signalings, does not for example dispose HS-PDSCH by 01111 expression TS2, and the time slot of last 5 bits of HS-SCCH indication expression TS0, TS3 to TS6 can be scheduled so, be set to 1 expression scheduling, not scheduling of 0 expression.
Mode 2, represent the scheduling of TS0 separately by reserved bit, 1 expression scheduling, 0 expression TS0 does not dispatch.
Mode 3, implicit representation.For example representing by CCS, is example with HS-SCCH Type1, requires start code smaller or equal to stop code among the CCS.11110000 expression SF=1.CCS can be overturn so, promptly use start code to be scheduled greater than stop code (11110000 do not use) expression TS0.
On the basis of above-mentioned three kinds of modes, can use following channel code indication scheme:
As long as mode 1 has indicated TS0 to be scheduled, all time slots use identical channelization code information so, and promptly TS0 uses identical channelization code information with TS2 to TS6, and channelization code information is still used the CCS indication;
As long as mode 2 has indicated TS0 to be scheduled, the channelization code resource of TS0 is used the channelization code resource of high-rise notice so, and this information can be passed through broadcast or RRC signaling UE.Other time slot uses the channelization code information of identical CCS indication.
As long as mode 3 has indicated TS0 to be scheduled; Whether the channelization code resource of TS0 uses the channelization code resource of high-rise notice by the indication of 1 bit so.For example, this bit is set to 0 expression, and the channelization code resource of TS0 is used the channelization code resource of high-rise notice; Other time slot uses the channelization code information of identical CCS indication; This bit is set to 1 expression, and all time slots use identical channelization code information, and promptly TS0 uses identical channelization code information with TS2 to TS6, and channelization code information is still used the CCS indication.This specific bit can be the reserved bit on the present control channel, also can be the bit of appointment, for example 1 bit of CCS is done this indication etc.
