Problems solved by technology

If the method once suggested in WCDMA is used, two channel codes are allocated for each uplink enhanced user equipment (referred to as UE) for transmission of uplink signaling. In addition, channel resources need to be allocated for transmission of downlink signaling. Transmission takes up too much channel resources

Embodiment

[0072] First with the LCR-TDD system, TTI Ser = 10ms, TTI UCtrl = TTI DCtrl = 5ms, the EUCH uplink dedicated control channel and the EUCH traffic channel are allocated in the same time slot as an example, such as Figure 5 shown. It is assumed that N=2 S&W HARQ can guarantee continuous transmission of UE data. UE in each TTI Ser The included second subframe sends H OB and E-TFI, corresponding to different HARQ processes. The transmission interval of SI depends on the arrival of new data in the UE buffer, in the corresponding TTI Ser contained in the first subframe sent. Node-B at each TTI Ser The included first subframe sends ACK / NAK, corresponding to different HARQ processes. The sending interval of SA depends on the arrival interval of SI, in the corresponding TTI Ser The 2nd subframe included is sent. The EUCH uplink dedicated control channel and EUCH traffic channel are allocated in time slot 1, and the EUCH downlink dedicated control channel is allocated in tim...

Abstract

An alternative signaling transmission method includes such steps as determining the least scheduling interval, allocating up and down control channels, dividing up (or down) signaling into several parts, alternatively transmitting them in different time slots, and distinguishing the contents of up (or down) signaling by using a parameter relative to time.

Description

technical field [0001] The present invention relates to uplink data services, in particular to a signaling transmission method for uplink channel enhancement (EUCH for short). Background technique [0002] Uplink dedicated channel enhancement is a research project proposed in version 6 of the Third Generation Partnership Project (hereinafter referred to as 3GPP) and being standardized. The purpose of the EUDCH is to effectively manage and plan the uplink transmission resources through the wireless network, improve the uplink capacity of the system, and make it suitable for the transmission of bursty data services. By improving the performance of the uplink dedicated transmission channel, the coverage and throughput of the cell are improved, the uplink transmission rate is increased, and the uplink delay is reduced. For the Time Division Multiplexing (abbreviated as TDD) system, it is not finally determined whether the object of uplink enhancement is a shared channel or a de...
