Indicate the non-whole time slot and the code channel resource on these time slots in non-rectangle resource;
Up, descending time slot non-whole time interval resource distribution can be simultaneously indicated in auxiliary resources channel, it is also possible to single
Solely indicate up or descending time slot non-whole time interval resource distribution;
Specifically:Time slot instructions field can be to adopt bitmap modes to indicate which time slot is non-whole time slot;
For example, N number of bit indicates N number of time slot, and each bit can value 0 or 1;Can arrange:Value represents the bit table for 1
The time slot for showing is non-whole time slot, and it is not non-whole time slot that value is 0 time slot for representing that the bit represents;Vice versa;For example:For
TD-SCDMA system totally 7 uplink and downlink timeslots, can adopt 7 bits to indicate the non-whole time interval resource of TS0 to TS6 totally 7 time slots
Distribution.Preferably, it would however also be possible to employ less bit indicates some specific time slots(In system resource allocation, these time slots
Most possibly become non-whole time slot)Whether be non-whole time slot, such as can using 4 bits represent TS0, TS1, TS5, TS6 this 4
Which time slot is non-whole time slot in individual descending time slot;Specific time-gap number can be arranged by network and terminal or network passes through
High-level signaling notifies terminal.
For the code channel of non-whole time slot is indicated, can be in the following way:
Specifically, for each non-whole time slot, the indicating means of code channel is indicated using bitmap modes:K ratio is refered in particular to
In the case of showing the distribution condition of K code channel, such as K=8, whether the resource on the empty code channel of 8 bits 8 2XSF16 of instruction
Distribution;Can arrange:Value represents the corresponding code channel of the bit and is scheduled to terminal and carries out data transmission for 1, and value is that 0 represent should
The empty code channel that bit is represented is not scheduled to terminal to carry out data transmission;Vice versa.
Specifically, for each non-whole time slot, the periodic feature information of the non-whole time interval resource of terminal can be notified, to tool
There are the different cycles of the non-whole time interval resource of cyclically-varying feature, different code channel situations to be numbered, network is arranged with terminal
Or network is notified the numbering on auxiliary resources channel by signaling the periodic resources implication of each numbering instruction of terminal
Terminal;
Specifically, for each non-whole time slot, code channel indicates that the code channel resource in existing HSDPA can also be adopted to indicate
Mode, using C(C is even number)Individual bit is indicated;C/2 bits indicate resource starting code channel position, and in addition C/2 bits indicate resource
Terminate code channel position;
Specifically, for each non-whole time slot, code channel is indicated can also be using code channel resource instruction side in existing HSUPA
Formula, i.e. CRRI indicate the numbering of the upper node of ovsf code tree;
The code channel indication bit of all time slots is set in code channel instructions field, and such as 7 time slots, each time slot adopts above-mentioned
Bitmap modes need 8 bits, then code channel instructions field needs altogether 56 bits;It is preferred that code channel instructions field is only distributed most
Greatly may the code channel of non-whole time slot of number indicate, such as, it is believed that 4 non-whole time slots at most occurs in system, then only need point
Indicate respectively the code channel resource of 4 possible non-whole time slots with 4 bit groups, now according to it is non-whole in non-whole time slot instructions field when
The order that gap occurs sets gradually the code channel indication bit group of each non-whole time slot;
Mode 2, indicates to carry code channel instructions field to indicate the code channel on non-whole time slot by it on channel in auxiliary resources
Resource situation, network and terminal arrange or network by each bit group in high-level signaling notification code road instructions field it is corresponding when
Gap;
In which, only occurs code channel instructions field on auxiliary resources channel, the instruction of code channel can be adopted and phase in mode 1
Same method:That is bitmap modes, existing HSDPA code channels indicating mode and existing HSUPA code channels indicating mode;
Specifically, code channel instructions field is whole is sequentially arranged the code channel resource that M bit group indicates respectively M time slot, net
Network and terminal are arranged or network notifies the corresponding time-gap number of each bit group by high-level signaling;If the value of bit group is spy
Definite value --- such as " 00000000 ", then it represents that the corresponding time slot of bit group is not non-whole time slot(It is not that non-whole time slot refers to this
All code channels of time slot can be used for shared channel transmission or all code channels are used as control channel transmission), otherwise represent the bit
The corresponding time slot of group is non-whole time slot, and now network indicates code channel resource with the bit group by the code channel indicating means of agreement;
Auxiliary resources based on said method indicates channel, can adopt the public RNTI scramblings of an agreement or adopt
UE-Specific RNTI are scrambled.Further, the auxiliary resources that UE-Specific RNTI are scrambled is adopted to indicate that channel can be with
It is a kind of and existing HS- in reserving by arranging order type indication bits using existing HS-SCCH order channels
SCCH order distinguish and represent be the HS-SCCH order channels be auxiliary resources indicate channel;
Auxiliary resources indicates that the transmission position of channel can be allocated to terminal or by network and end by network by high-level signaling
End agreement is determined by terminal repeated detection;Auxiliary resources channel can all send in each frame or enter according to the fixed cycle
Line period sends or sends only when non-rectangle distribution of resource changes;Auxiliary resources indicates the non-rectangle that channel is indicated
Resource can come into force working as in frame scheduling, it is also possible to indicate when coming into force of non-rectangle resource by addition entry-into-force time domain on the channel
Between.
Whether network can also be needed by high-level signaling configuration or a bit instruction terminal on physical control channel
Receive the data dispatch of above-mentioned non-rectangle;If network instruction terminal need not receive above-mentioned non-rectangle data dispatch, terminal is not
Need to monitor above-mentioned physical channel, only carry out data transmission according to the instruction of control channel;
Base station for terminal scheduling when, if the scheduling of resource comprising non-whole time slot, base station is in control channel(It is up:
E-AGCH;It is descending:HS-SCCH)In TRRI in by the time slot set;
