Embodiment

[0079] The present invention mainly relates to a transmission method of uplink scheduling signaling used for uplink channel enhancement in the LCR-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.

[0080] According to the uplink time slot structure of LCR-TDD and the formula (1)-(4) that the present invention provides, assume that TPC is 2 bits, SS is 2 bits, N TFCIi , N DCCH0 and N DCCH1 = 0, when the TTI is equal to 5 ms, a possible subset of data transmission rate expected by the user for the enhanced uplink channel (EUCH) is shown in Table 3.

Abstract

The method includes steps: terminal sends n bits of up going dispatching information including suffix bits relevant to user expected data rate, and information of current power sent by user; encoding the said n bits stream; the coded bits are sent to operation of rate match so as to form data stream including 88-m bits; carrying out interweaving for second time for the said generated 88-m bits data stream; inserting SS and TPC bits including m bits into interweaved bit stream so as to form data burst format, which are sent to Node B on specified code word at specified time slot. Reporting data rate expected by UE to Node B, the invention optimizes scheduling strategy, and reduces number of bit of up going signaling needed by up going scheduling. Features are: better satisfying time delay requirement, increasing scheduling flexibility, raising throughput of sub zone, and service coverage of system.

Description

technical field [0001] The present invention relates to a code division multiple access (abbreviated as CDMA) mobile communication system, in particular to 1.28Mcps low rate time division duplex code division multiple access mobile communication system (abbreviated as LCR-TDD), uplink scheduling for uplink channel enhancement Signaling 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 technical ...
