Resource allocation and control signaling transmission method

Abstract

The invention discloses a method for resource allocation and control signaling transmission. A base station divides a bandwidth of a system into relatively-smaller child bandwidth groups and divides physical resource to be allocated into the groups the same as above, and then allocates different user equipment terminals in the resource blocks of one or more of the child bandwidth groups. Moreover, the base station transmits the information of user equipment resource allocation based on the resource allocation method provided in the invention, to the user equipment via the physical resource allocation control signaling provided in the invention, so as to facilitate the user equipment to recover the information transmitted in the allocated resources.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method for resource allocation and control signaling transmission. Background technique [0002] 3GPP is a standardization organization that formulates wideband code division multiple access (WCDMA) technical specifications, and has released various versions of technical specifications related to wireless access networks and core networks. The above-mentioned wideband code division multiple access (WCDMA) system is based on orthogonal spread spectrum codes to allow multiple users to simultaneously transmit system and user information within a 5MHz bandwidth. The data rate is 2Mbps; since the above-mentioned maximum data transmission rate still can not meet the increasingly diverse service transmission requirements, the 3GPP standardization organization then respectively based on the high-speed downlink packet for the downlink from the base station (BS) to the ...

Problems solved by technology

The above wideband code division multiple access (WCDMA) system is based on orthogonal spread spectrum codes to allow multiple users to simultaneously transmit system and user information within a 5MHz bandwidth. The data rate is 2Mbps; since the above-mentioned maximum data transmission rate still cannot meet the increasingly diverse business transmission requirements, the 3GPP standardization organization subsequently separately based the high-speed downlink packet on the downlink from the base station (BS) to the user equipment (UE) Access (HSDPA) and the uplink from the user equipment (UE) to the base station (BS) based on technologies such as High Speed ​​Uplink Packet Access (HSUPA) to enhance the uplink and downlink of the Wideband Code Division Multiple Access (WCDMA) system Transmission capacity, so that in theory the maximum peak rates of the uplink and downlink bearer services are about 5.76Mbps and 14Mbps respectively; due to the transmission capability of the enhanced Wideband Code Division Multiple Access (WCDMA) system is still not able to meet the high Due to the business requirements of transmission bandwidth, it is necessary to introduce new wireless transmission technology and network architecture to evolve the above-mentioned Wideband Code Division Multiple Access (WCDMA) system, which is why 3GPP is applying Orthogonal Frequency Division Multiplexing (OF
