Embodiment Construction

[0015] The present invention will be described with reference to the accompanying drawings, in which the same symbols represent the same components. The invention is applicable to complete discontinuous transmission and partial discontinuous transmission. As will be explained in detail later, for partial discontinuous transmission, the transmitted code and time slot can be determined from the received TFCI, as well as the radio frame in the shortest TTI in the CCTrCH. Subsequently, the receiver will be turned off during the period of not using codes and time slots indicated by the received TFCI for TTI. For completely discontinuous transmission, after receiving the TFCI, the receiver will be turned off during all codes and time slots in the TTI. reference figure 2 , Shown is a flowchart of the program 10 used to save power during partial discontinuous transmission. Reference will also be made at 10 o'clock in the explanation of the program figure 1 CCTrCH example shown. Program ...

Abstract

The present invention achieves power savings by turning off all or some of the baseband processing for codes and timeslots that have not been transmitted due to full or partial DTX. With respect to partial DTX, the transmitted codes and associated timeslots and radio frames within the shortest TTI in the CCTrCH are determined from the received TFCI. Thereafter, the receiver is turned off for the unused codes as indicated by the received TFCI. With respect to full DTX, following TFCI reception, the receiver is turned off for all timeslots within the shortest TTI.

Description

Technical field [0001] The present invention relates to the field of wireless communication. Specifically, the present invention relates to a time-sharing full-duplex (TDD) system with a high chip rate and a low chip rate to save power in the full and partial discontinuous transmission (DTX) operation mode. Background technique [0002] For the third-generation mobile communication partner project (3GPP) time-sharing full-duplex (TDD) system, time can be divided into transmission time intervals (TTI) that can be subdivided into several frames, which can be further subdivided It is a number of time slots. 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 divided into several time slots. The coded combined transport channel (CCTrCH) includes one or more transport channels (TrCH). CCTrCH can be mapped to a group of more than ...
