Embodiment Construction

[0021] The solution of the invention is to perform proper buffer processing between the source of the original rate (that is, the TD-SCDMA terminal) and the baseband processing, complete the buffering and flow control of the uplink original data, and then send it to the baseband.

[0022] In the present invention, a threshold is set on the TD-SCDMA terminal, and when the buffered uplink original data reaches the threshold, the data is sent to the baseband. The threshold can be the amount of data at the full rate of N TTIs (transmission time intervals), where N is an integer greater than or equal to 1. When the cached upstream raw data does not reach the threshold, the data is always cached and sent to the baseband rate is 0. In addition, in order to guarantee the QoS requirements of delay and jitter, a timer can be set, and when the accumulated time of the buffered uplink raw data reaches the time set by the timer, even if the above threshold is not reached, the cached The up...

Abstract

The invention discloses a power-saving method for time-division synchronous code-division multi-access terminals. The method comprises the following steps: (1) a threshold is arranged on a time-division synchronous code-division multi-access terminal; (2) the time-division synchronous code-division multi-access terminal caches uplink original data, and when the cached uplink original data reachesthe threshold, the cached uplink original data is sent to a baseband. The method caches data between an original rate source and the baseband so as to complete expected rate adjustment, and can obtain effects of saving power and improving empty-port performance.

Description

technical field [0001] The present invention relates to a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) terminal, in particular to a power saving method for a TD-SCDMA terminal. Background technique [0002] For the interactive and background services in the uplink direction of TD-SCDMA terminals, the ups and downs of the uplink rate (the rate may vary from 0 to the standard value according to the service usage) are common. For the uplink of the TD-SCDMA system DPCH (Dedicated Downlink Physical Channel, dedicated physical channel), different rate fluctuations in the uplink direction will produce two results in the uplink baseband of TD-SCDMA: [0003] 1. If the uplink rate drops to 0, uplink DTX (Discontinuous Transmission) starts; [0004] 2. If the uplink rate is lower than the standard configuration but not 0, the uplink direction will fully occupy the allocated physical resources through rate ...
