Embodiment

[0054] The present invention mainly relates to a transmission method of downlink scheduling signaling used for uplink channel enhancement in the LCR-TDD system. Therefore, in the following examples, it is related to the specific scheduling mode, uplink scheduling signaling content and transmission of Node B Ways and so on are omitted.

[0055] Since the time domain is already included in the downlink signaling information, the rate channel code set only needs to consider the single time system. With reference to the single-time situation given in the patent invention [Transmission method of uplink scheduling signaling for low-rate time-division duplex systems], when the transmission time interval (TTI) is 10ms or 5ms, the expectation of the UE for scheduling requirements Rate set, as shown in Table 1. (Note: For the sake of simplicity, in the present invention, the expected rate sets corresponding to the 10ms and 5ms TTIs are represented by a table, because in these two cases, onl...

Abstract

The method includes following steps: the base station sends out the suffix code indicating bits of TFRCI and the downlink scheduling information of time-domain including n bits; the downlink scheduling bit stream with n bits is encoded by using convolution code whose encoding rate is 1 / 3 or block code; a rate adaptation operation is made for the encoded bits to form a bit stream with 88-m bits; the second interleave is made for the bit stream with 88-m bits; TPC bits and SS bits is inserted into the interleaved bit stream to form the data burst format that is transmitted to the appointed UE in the appointed downlink schedule control channel. The invention sets a time domain in the downlink schedule signaling to implement flexible configuration for time domain occupied by EUCH and so to optimize the schedule strategy of Node B.

Description

Technical field [0001] The present invention relates to a code division multiple access (CDMA for short) mobile communication system, in particular to a 1.28 Mcps low rate time division duplex code division multiple access mobile communication system (abbreviated as LCR-TDD) for downlink scheduling for uplink channel enhancement Information transmission method. Background technique [0002] The Third Generation Partnership Project (referred to as 3GPP) is a technical standardization organization that implements the third generation mobile communication system. The third generation mobile communication technology standards include frequency division duplex (FDD) and time division duplex (TDD) modes. Since its establishment, 3GPP has published the third-generation mobile communication system technical standards including Frequency Division Duplex (FDD) and Time Division Duplex (HCR-TDD) of 3.84Mcps respectively in October 1999, referred to as Release 99; in 2000 In 2016, the third-...
