Method for transmission of down common control information in tme-division duplex system

Abstract

The invention discloses a transmitting method of downwards public control information in time division duplex system, which includes following steps: A. processes the upper control information with variant types in preset control period, forms the data block of themselves, transmits to the reality of media access control layer, the physical layer concentrates the physical layer control information in the period, forms the physical layer control information data block; B. the process unit on MAC layer acquires the resource occupying state, and dispatches all the upper control information data block according to the state, and cascades the dispatched data blocks, forms the upper data package catering to the current resources occupying state of the physical layer and transmits to physical layer; C. the physical layer cascades the physical layer control information data block preset in the control period and the received upper data package, and carries on uniform physical layer modulating and coding process, and transmits out with broadcast through physical layer in preset period.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and in particular to a method for transmitting downlink public control information in a wireless communication system for high-speed data service transmission. Background technique [0002] At present, with the continuous development of wireless communication technology, high-speed data services such as web browsing and FTP download have entered the field of wireless communication technology, and gradually become the development direction of the field of wireless technology. These high-speed data services are usually asymmetrical in the uplink and downlink, and the amount of downlink service data is much larger than that in the uplink. This feature is more suitable for time division duplex (TDD) systems, because the uplink and downlink occupy the same frequency band and are separated in time. Different uplink and downlink traffic uses flexible time slot allocation methods to im...

Problems solved by technology

[0017] It can be seen that this method realizes the optimization of public control information transmission in the process of high-speed data service transmission, but this system is an FDD system, which will cause waste of uplink spectrum resources for high-speed data services with asymmetric uplink and downlink traffic volumes

[0018] In view of this, a system supporting high-speed data transmission based on the TDD system is currently proposed. The physical layer control information FPACH generated during the random access process of this system has a large amount of information, so there is a need for downlink high-level common control information and physical layer Problems of Controlling Information Common Processing
