Embodiment Construction

[0015] The invention will be described with reference to the drawings, in which like symbols refer to like components. The present invention is applicable to full discontinuous transmission and partial discontinuous transmission. As will be explained in detail later, for partial discontinuous transmission, the received TFCI can determine the transmitted code and time slot, as well as the radio frame in the shortest TTI among CCTrCHs. Then, the receiver is turned off during the non-used codes and time slots indicated by the received TFCI for the TTI. For full discontinuous transmission, the receiver is turned off during all code timeslots within the TTI after the TFCI is received. refer to figure 2 , shows the flow chart of the procedure 10 for saving power during partial discontinuous transmission. Procedure 10 will also be explained with reference to the CCTrCH example shown in FIG. 1 . Procedure 10 starts by reading the TFCI at the shortest TTI start position between TrC...

Abstract

The present invention provides a method for saving power during discontinuous transmission (DTX) of a TDD receiver, the method comprising receiving a transport format combination pointer (TFCI) of a coded composite transport channel (CCTrCH) having a plurality of transport channels (TrCH), each TrCH contains at least one code and time slot and has an associated transmission time interval (TTI) consisting of at least one radio frame, then the transmitted code, time slot and CCTrCH are determined from the received TFCI radio frames in the shortest TTI among them, and turn off the receiver when no codes and time slots are transmitted in the shortest TTI. The purpose of power saving can be achieved by turning off the baseband processing of all or part of the coding time slots that are not necessary to transmit during discontinuous transmission.

Description

technical field [0001] The present invention relates to the field of wireless communication. Specifically, the present invention relates to power saving functions for high chip rate and low chip rate Time Division Duplex (TDD) type systems in full and partial discontinuous transmission (DTX) modes of operation. Background technique [0002] For 3rd Generation Partnership Project (3GPP) time-division full-duplex (TDD) systems, time is divided into Transmission Time Intervals (TTIs), which can be subdivided into frames, which can be further subdivided for several time slots. A TTI can be defined as one or more radio frames. Specifically, a radio frame is 10ms; and a TTI may be 10, 20, 40 or 80ms. TDD with a low chip rate divides each frame into two subframes. These subframes can be subdivided into several time slots. A Coded Composite Transport Channel (CCTrCH) consists of one or more Transport Channels (TrCH). A CCTrCH can be mapped to a group of more than one slot grou...
