Embodiment

To combine accompanying drawing and embodiment that technical scheme of the present invention is explained in more detail below.

Following flow process has been described the distribution method of HS-SICH when adopting the HS-SCCH-less operation in the TD-SCDMA system according to the consensus standard message interaction process.

As shown in Figure 1, the HS-SICH configuration flow comprises:

(11) RNC (radio network controller) sends RRC (Radio Resource control) message to UE, wherein carries its spendable HS-SICH configuration information and HS-PDSCH resource information that NodeB distributes for this UE.Wherein, this RRC message can but to be not limited to be that RRC sets up message, RB (radio bearer) reconfiguration message, transmission channel reconfiguration message, physical channel reconfiguration message or cell update acknowledgement message;

(12) UE is after receiving above-mentioned RRC message; Preserve wherein HS-PDSCH resource information and the configuration information of HS-SICH, and receive the data that NodeB passes through this HS-PDSCH initial transmission in this configuration information HS-PDSCH resource information that the back carries in according to message that comes into force; As receive success, then this UE send HS-SICH according to above-mentioned HS-SICH configuration information configuration concurrency, wherein carries HARQ ACK (affirmative acknowledgement) feedback information; Otherwise this UE send HS-SICH according to above-mentioned HS-SICH configuration information configuration concurrency, wherein carries HARQ NACK (negative response) feedback information, or does not send this HS-SICH;

This shows; Said method passes through to be more pre-configured HS-PDSCH physical channel resources of UE and HS-SICH resource, and combines the blind Detecting technology, makes that NodeB need not send HS-SCCH when initial HARQ transmitted; UE also can carry out the reception of data according to pre-configured HS-PDSCH resource; And use pre-configured HS-SICH correspondingly to feed back or do not feed back according to reception result, and promptly having realized the HS-SCCH-less method, the UE of this moment can think and is under the HS-SCCH-less state.After executing above-mentioned steps (12); If NodeB receives corresponding N ACK feedback information or does not receive the HS-SICH channel in time slot corresponding; Then it issues dispatching command through HS-SCCH; The HS-PDSCH resource information of dynamic assignment mandate is given UE, and on this authorization resources, retransmits the data of above-mentioned initial transmission failure; And be in this UE under the HS-SCCH-less state after receiving the dispatching command that issues through HS-SCCH; Can finish the HS-SCCH-less state; And use the HS-PDSCH resource of indicating in the HS-SCCH dispatching command to receive data, and use the HS-SICH corresponding to feed back corresponding reception result finishing receiving the back with this HS-SCCH at this TTI.As when the predefined reception resource of the next one reaches; UE does not receive the dispatching command that NodeB issues through HS-SCCH; Then UE can rotate back into or keep the HS-SCCH-less state; Pre-configured HS-PDSCH resource is carried out Data Receiving in the continuation use step (12), and uses (disposing through RRC message or following HS-SCCHORDER) HS-SICH of up-to-date effective configuration that reception result is correspondingly fed back or do not feed back.

When perceiving, NodeB is necessary to revise that the UE that is under the HS-SCCH-less state is employed when being used to feed back initial transmission Data Receiving result's HS-SICH, and as shown in Figure 2, may further comprise the steps:

(21) NodeB sends HS-SCCH ORDER message through a HS-SCCH to UE, carries the sign of revising UE employed new HS-SICH in back through this in this message.This sign can be the serial number information of this HS-SICH in HS-SICH tabulation, and this HS-SICH tabulation can be handed down to UE through the RRC message in the above-mentioned steps (11) together with above-mentioned preconfigured information by RNC, UE after receiving with under its preservation; In this HS-SICH tabulation, preserve every can employable HS-SICH code channel, time slot and Midamble (training sequence) sign indicating number wait the indispensable information that disposes HS-SICH;

(22) after UE receives above-mentioned HS-SCCH ORDER message; Use the HS-SICH corresponding to this HS-SCCH ORDER message sink success of NodeB feedback with this HS-SCCH; And be identified at the configuration information that finds corresponding HS-SICH in its up-to-date HS-SICH tabulation that receives according to this; And after configuring HS-SICH with this configuration information, the reception result of initial transmission data is correspondingly fed back or do not feed back with this HS-SICH.

The HS-SCCH ORDER message of sending in the above-mentioned steps (21) is a kind of special frame format of on the basic frame format of HS-SCCH basis, deriving out among the HSPA+ (evolution scheme that high-speed packet inserts), can be used for carrying DTX (discontinuous emission)/DRX (discontinuous reception) relevant information at present.The basic frame format of HS-SCCH is as shown in table 1, and a kind of possible frame format of HS-SCCH ORDER message proposed by the invention is as shown in table 2.

The basic frame format of table 1 HS-SCCH

Code channel information	Gap information	Modulating mode	The transmission block size	HARQ information
					8bits	5bits	1bit	6bits	7bits

Table 2 possible HS-SCCH ORDER frame format

Code channel information	Command type	Command context
			5bits	3bits	19bits

Wherein, the code channel information of 5bits is used to represent the type of this message, preferably uses 11110 to represent that this message is HS-SCCH ORDER message; In command type, represent that with a specific 3bits character this message is the message that is used to revise the configuration information of HS-SICH; The command context of 19bits can have various structure according to the difference of command type.When command type was long grant, command context part (19bits) a kind of possible frame format was as shown in table 3.

A kind of possible frame format of table 3 command context part

Code channel information	Gap information	Modulating mode	Keep	The HS-SICH sign
					8bits	5bits	1bit	3bits	2bits

Consider that the corresponding transmission block size of different code channels maybe be different; Can in advance that different resource is corresponding transmission block size divide into groups; And the transmission block size that every kind of resource is corresponding is integrated in the resource correspondence table and through passing to UE in the RRC message, and in HS-SCCH ORDER command context, provides the ID of resource and set group.Based on above-mentioned consideration, the another kind of possible frame format of command context part (19bits) is as shown in table 4.

The another kind of possible frame format of table 4 command context part

Resource index	Initial code channel information	Gap information	Initial offset	Keep	The HS-SICH sign
						4bits	4bits	5bit	3bits	1bit	2bits

Wherein, Initial code channel information has provided the initial code channel resource of the operable HS-PDSCH resource of UE; And because the code channel resource that UE uses must be continuous, UE can obtain the code channel resource number in the single time slot according to resource index in the resource correspondence table that it is received.The formation of resource correspondence table can be: the transmission block size of supporting under number of resources (the operable resource number of UE in the TTI is a unit with RU (resource units), a sign indicating number when 1 RU is defined as SF16), this resource.Since the UE number of resources of in a TTI, authorizing can by: the operable number of time slots of operable RU number * UE obtains in each time slot of UE; Therefore, the code channel number that can in each time slot, use through resource index and the anti-UE of release of gap information of UE.And initial offset is used for the skew in computation cycles length.But this part also can be omitted, and omits back UE and can calculate initial offset according to the time that receives HS-SCCH ORDER.

Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
