Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] When configuring scheduled transmission and non-scheduled transmission on the uplink physical channel E-PUCH at the same time, the embodiment of the present invention is mainly to: determine the common SS command for scheduled transmission and non-scheduled transmission in the current subframe; according to the determined SS command, adjust The timing advance TA of the uplink physical channel E-PUCH, or determine the common TA of scheduled transmission and non-scheduled transmission in the current subframe, and adjust the TA of the uplink physical channel E-PUCH in the current subframe to the determined TA, This can improve synchronization control accuracy when scheduled transmission and unscheduled transmission coexist.

Abstract

The invention discloses a synchronization controlling method and a synchronization controlling device of a high-speed uplink packet access technique, which simultaneously realize the configuration of scheduled transmission and unscheduled transmission of physical uplink channels E-PUCH, and the synchronization controlling method comprises the following steps: a common SS command of scheduled transmission and unscheduled transmission in a present sub-frame is determined; a timing advanced amount TA of the physical uplink channels E-PUCH is adjusted according to the determined SS command; alternatively, a common TA of scheduled transmission and unscheduled transmission in the present sub-frame is determined, and the TA of the physical uplink channels E-PUCH in the present sub-frame is adjusted to be the determined TA. The synchronization controlling method and the synchronization controlling device of the high-speed uplink packet access technique can improve the synchronization controlling precision when scheduled transmission and unscheduled transmission coexist.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a synchronization control method and device in a high-speed uplink packet access technology (HSUPA: High Speed ​​Uplink Packed Access). Background technique [0002] In order to support HSUPA features, Time Division Multiplexing Code Division Multiple Access (TD-SCDMA) system uplink newly adds uplink dedicated channel (E-DCH), uplink enhanced control channel (E-UCCH) and uplink enhanced random access channel (E-RUCCH). Among them, E-DCH is a transmission channel for carrying high-speed uplink data; E-UCCH and E-RUCCH are two control channels for transmitting control information related to uplink enhancement. And, multiple UEs can share the three channels through time division multiplexing and code division multiplexing. [0003] In an application, the E-UCCH is usually multiplexed with the E-DCH to transmit HARQ-related information of the current E-DCH. E-RUCCH is map...
