Embodiment

[0094] The present invention mainly relates to a transmission method for uplink scheduling signaling used for uplink channel enhancement in the HCR-TDD system, so in the following example, the scheduling method of Node B, the content of downlink scheduling signaling and the transmission method, etc. somewhat omitted.

[0095] According to the uplink time slot structure of HCR-TDD and the formula (1)-(5) that the present invention provides, suppose N TPC = 2 bits, N TFCI , N DCCH1 , and N DCCH2 =0, Table 4 shows an example of a possible user-desired data transmission rate subset for enhanced uplink channel (EUCH).

Abstract

The method includes following steps: in term of current emitting power, data buffer and QoS message of transmission service, UE determines an initial expecting bit rate; combines the subscript corresponding to the bit rate and emitting power to form the up stream dispatching message; on the appointed up stream channel, UE encodes and modulates the up stream dispatching message, and then sends it to base station; after NodeB receives the up stream dispatching message, it analyzes the message, and selects a part of UE allowed to transmit at time quantum in next dispatching period; NodeB makes answering to UE through control channel appointed by down stream dispatch; at down stream channel, in term of the received down stream dispatching signaling, selects appropriate current bit rate; UE transmits the data according to the selected bit rate.

Description

technical field [0001] The present invention relates to Code Division Multiple Access (abbreviated as CDMA) mobile communication system, in particular to 3.84Mcps high rate Time Division Duplex Code Division Multiple Access mobile communication system (abbreviated as HCR-TDD), uplink scheduling signaling for uplink channel enhancement the transmission method. Background technique [0002] The 3rd Generation Partnership Project (abbreviated as 3GPP) is a technical standardization organization implementing the 3rd generation mobile communication system, wherein the 3rd generation mobile communication technology standard includes Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes. Since its establishment, 3GPP has announced in October 1999 the third-generation mobile communication system technical standards, which mainly include 3.84Mcps Frequency Division Duplex (FDD) and Time Division Duplex (HCR-TDD), referred to as Release 99; in 2000 In 2018, the technic...
