Embodiment Construction

[0058] In order for the base station to know whether the TD-LTE terminal of the early version (such as the TD-LTE terminal of Rel9 / Rel10) supports the above-mentioned new special subframe configuration, the embodiment of the present invention provides the following solutions: (1), through a specific The FGI (Feature Group Indication, feature group indication) bit indicates whether the terminal supports the above-mentioned new special subframe configuration. (2) The base station tentatively schedules downlink transmission to the terminal on the DwPTS. If the terminal does not correctly receive feedback on the downlink transmission from the terminal, the terminal does not support the above-mentioned new special subframe configuration. (3) The base station judges whether the terminal is a roaming terminal. If it is a roaming terminal, it considers that it does not support the above-mentioned new special subframe configuration, otherwise it considers that it supports the new specia...

Abstract

The invention discloses a data processing method, device and system. The method includes: the base station obtains the UE capability report message containing the specific FGI bit sent by the terminal of the early version TD-LTE; and judges whether the terminal supports specific special subframe configuration according to the FGI bit. Or, the base station schedules downlink transmission to the terminal on the DwPTS; if correct feedback for the downlink transmission is received, it is determined that the terminal supports a specific special subframe configuration. Alternatively, the base station judges whether the terminal is a roaming terminal; if not, determines that the terminal supports a specific special subframe configuration. Through the embodiment of the present invention, the base station can determine whether the R9 / 10 terminal supports the new special subframe configuration in Rel11, and can perform downlink transmission accordingly, effectively improving the effectiveness of downlink transmission.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a data processing method, device and system. Background technique [0002] A 10ms wireless frame of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system consists of two 5ms subframes, and each subframe consists of seven normal time slots (uplink time slot, downlink time slot), and a special time slot. The duration of an uplink time slot or downlink time slot is 0.675ms, and the duration of a special time slot is 0.275ms. Among them, the special time slot consists of three parts: DwPTS (Downlink Pilot Time Slot, downlink pilot time slot), GP (Guard Period, protection time) and UpPTS (Uplink Pilot Time Slot, uplink pilot time slot). [0003] A 10ms radio frame of the TD-LTE (Time Division-Long Term Evolution) system consists of two half-frames of 5ms, and each half-frame consists of five subframes of 1ms. Subframes in the TD-LTE system i...
