Embodiment Construction

[0036] Aiming at the uplink subframe bundling function in the uplink scheduling of the MAC (Medium Access Control, medium access control) layer in the LTE system, the present invention proposes a technology for realizing uplink subframe scheduling during subframe bundling. In general, through a large number of simulation experiments, it is found that in the uplink subframe bundling mode, the period for the base station to send uplink scheduling instructions to the same terminal follows a certain rule. Therefore, according to the TDD uplink and downlink time slot ratio relationship, functional entities such as the MAC layer can determine whether the terminal can send data on the PUSCH at the current moment according to the currently scheduled subframe number.

[0037] Specifically, one can execute as figure 1 Operation shown:

[0038] 1. In the background cell configuration, configure the algorithm parameters corresponding to TDD uplink and downlink time slot ratios 0, 1, and ...

Abstract

The invention discloses a method and a system for realizing uplink sub-frame dispatch in sub-frame binding, which perform uplink time slot dispatch on a terminal once at an interval of fixed sub-frame number according to uplink and downlink time slot matching relationship when enabling an uplink sub-frame binding function of the terminal. The technology for realizing uplink sub-frame dispatch in sub-frame binding provided by the invention dispatches the uplink sub-frame according to a fixed period to effectively reduce the expenditure necessary for uplink dispatching of the terminal as far as the uplink sub-frame binding function is concerned. Besides, a dispatch period can be dynamically allocated by the background to improve the execution flexibility of the sub-frame binding function.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing uplink subframe scheduling when subframes are bundled. Background technique [0002] The current general terrestrial wireless communication network adopts a cellular structure. Only one base station is deployed in a cell. This is a typical star network, and the channel quality of users at the edge of the star network will deteriorate due to various interferences. In the LTE (Long Term Evolution, Long Term Evolution) system, the main performance is that the retransmission probability of the uplink HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat request) will increase greatly, and the communication delay will increase. The uplink subframe bundling technology is to send the same data in four consecutive uplink TTIs (Transmission Time Interval, transmission time interval) in the same HARQ process. This method can be applied to a sc...
