Embodiment

[0077] The present invention mainly relates to a transmission method of downlink scheduling signaling for uplink channel enhancement in the HCR-TDD system, so in the following example, the specific scheduling method, uplink scheduling signaling content and transmission of Node B methods are omitted.

[0078] Since the downlink signaling information already includes the time slot domain, the rate channel code set only needs to consider the case of a single time slot. Referring to the single-slot situation given in the patent [Transmission method for uplink scheduling signaling for high-rate time-division duplex systems], when the transmission time interval (TTI) is 10ms, the expected rate set of the UE is shown in Table 1, we can Get its corresponding possible data rate and channel code set, as shown in Table 2.

Abstract

A transmission method of down scheduling information for high-rate TDD system features that a rate channel code table is disclosed for decreasing the bits of down signaling as less as possible. When down signaling is transmitted by Node B, it is only needed to transmit the subscript indicators of relative options. According to this information, UE can know the maximal data rate, transmission format and channel code, which are allowed by Node B. Two time slot expressing methods are disclosed for flexible configuration of time slots.

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), used for uplink channel enhanced downlink scheduling information transfer 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...
