Abstract: A high speed uplink packet access data and signaling transmission method in the time divisional CDMA system includes data transmission and signaling transmission. The signaling transmission method includes the steps of: the UE applies channel coding to the Transport Format Combination, Retransmission Sequence Number and Hybrid Automatic Repeat Request Process Sequence Number; scrambling the encoded signaling; interleaving the scrambled signaling; speed matching the interleaved signaling according to the speed matching manner fixed by the perforating template; mapping the speed matched signaling to the physical channel. The present invention can allocate the resource flexibly and efficiently, and can avoid the negative impact to other UE uplink service caused by error de-spread.

Abstract: A method for realizing an automatic repeat request acknowledgement indicator channel (E-HICH ) in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system. Said method comprises the following steps: a system generates sequence codes which are used for firstly spreading (101); the system selects corresponding sequence codes for the data determined by a linking layer, and spreads them firstly (101); the system modulates and sums the data which is spread firstly (103, 104), and spreads secondly and scrambles the summed data (105); the system arranges the data which is spread secondly and scrambled according to a defined structure of time intervals for the automatic repeat request acknowledgement indicator channel (106). Said method could ensure the correctly receiving of information and save the resources of downlink channel.

Abstract: A method for timing among channels in the TD-CDMA system, aiming at the problem that in the existed TD-CDMA timing manner, UE searches the E-AGCH frequently and the power waste of UE is too much, which do not fit for TD-CDMA system. To solve the above problem, the method for timing among channels in TD-CDMA system includes the following steps: (1) the scheduling request initiated by user device to the base station ends; (2) after a first minimum time interval, the down-link E-AGCH channel is established between user device and the base station. This invention solves the timing relation between each of the HSUPA technique channels in TD-CDMA system, and makes them be adapted to the frame structure of TD-CDMA, prevents UE from searching E-AGCH frequently, reduces the power waste of UE, so the resource could be allocated more flexible and be fully utilized.

Abstract: The invention discloses a method for real-time service transmission and a method for resource allocation, wherein, the method for resource allocation of real-time service transmission includes the following processing: through resource allocation control channel, the base station allocates the semi-static service channel resource which is used for the initial transmission of hybrid automatic retransmission request of real-time service packet; wherein, before the base station performs to reconfigure or release the semi-static service channel resource, the terminal can use the semi-static service channel resource continually; through the resource allocation control channel, the base station allocates the dynamic service channel for the terminal which is used for the retransmission of hybrid automatic retransmission request of real-time service packet, wherein, the terminal can only use the dynamic service channel resource in allocated time. Through this invention, the real-time of the service transmission can be ensured and the control signaling cost can be reduced in service transmission, therefore, the Qos requirement of service can be ensured.

Abstract: A code channel resource allocation method of High Speed Uplink Packet Access in TD-SCDMA system involves the following steps: UE initiates an uploading authorization request to Node B through E-RUCCH or E-PUCH; after receiving the request, the Node B designates the spread spectrum code channel, code channel power and time slot for the UE using the scheduling algorithm according to the uploading information packet size, radio resource and UE service level condition in the message, and transmits to the UE through E-AGCH; the UE selects the appropriate modulation mode and transmitting packet size according to the spread spectrum code channel, time slot and code channel power transmitted through the E-AGCH; and the UE transmits the data to the Node B using the rate matching algorithm in the spread spectrum code channel and time slot allocated by the Node B. The present invention could realize the flexible resource allocation, the high availability and could avoid the disadvantageous influence to other UE uplink service because of false despreading.

Abstract: A transmission method for sharing non-scheduled resource and scheduled resource in an enhanced uplink system is disclosed. The invention is made to address the resource waste in prior art and the problem of unfair treatment for the user scheduled service in data transmission. The inventive transmission method for sharing non-scheduled resource and scheduled resource in an enhanced uplink system comprises the steps of: when an UE performing the uplink scheduled transmission and/or the non-scheduled transmission, the UE sharing the whole non-scheduled resource and scheduled resource to perform the uplink scheduled transmission and/or the non-scheduled transmission; wherein the types of the burst timeslots for the said non-scheduled transmission and the uplink scheduled transmission are the same. With the above method, the waste of the resource could reduced, and the problem of unfair treatment for the user-scheduled service could be solved, therefore the resource allocation could be more flexible and the resource usage could be higher.

Abstract: An implementation method of E-HICH in TD-CDMA systems is to solve the problem that the prior art can not achieve the accurate information reception and downlink channel resource saving. The method includes the following steps: the system generates the first-time spread-spectrum code sequence; the system chooses the corresponding first-time spread-spectrum code sequence for the data confirmed by the link layer and carries out the first-time spectrum spreading; assigns the TPC and SS pair for the user device at the same time; the system modulates and overlaps the first-time spreaded data, and carries out the second-time spectrum spreading and disturbing for the overlapped data; the system arranges the second-time spreaded and disturbed data according to the predetermined HICH time slot structure, inserts TPC and SS into corresponding positions. The present invention achieves both downlink channel resource saving and better receiving performance for UE. So the HARQ indicator information of E-DCH is received effectively and accurately.
