[0014]However, the existing MAC-hs PDU structure only supports the data multiplexing of DCCH and DTCH logical channels of the UE, but cannot support the new flexible The multiplexing method makes it impossible to support HSDPA technology well in the enhanced CELL_FACH state
Moreover, in the existing MAC-hs PDU structure, the HS-PDSCH channel in each TTI can only carry the dedicated data of a single user, cannot carry the dedicated data of multiple users, let alone carry the data multiplexing of multiple users

[0069] Figure 4 It is the first embodiment of the composition diagram of the MAC PDU in the enhanced CELL_FACH state, and will be described in detail below in conjunction with the method of the present invention.

[0070] Such as Figure 4 As shown, the MAC PDU includes: a version indication (VF, Version Flag) domain, a logical channel combination indicator (LCCI, Logical Channel Combination Indicator) domain, a BCCH / PCCH header, a CCCH / CTCH header, and a DCCH / DTCH header part, MAC service data unit 1 to MAC service data unit n, and the padding part.

[0071] Among them, the VF field is usually set at the beginning of the MAC PDU header and is used to indicate the version information of the MAC PDU. The typical size of the VF field is 1 bit. The VF domain can be omitted.

[0072] The LCCI field is set in the header of the MAC PDU and is used to indicate the combination of logical channel groups.

[0073] such as in Figure 4 Among them, according to the characteristics o...

Abstract

The invention discloses a method for realizing grouping access of high speed downlink. In the state of enhancing a CELL_FACH, the method includes the processes: a UE monitors an HS-SCCH and when data delivered by the HS-PDSCH in a TTI need to be received, according to the information carried by an MAC PDU, data from a BCCH, and / or a PCCH, and / or a CCCH, and / or a CTCH, and / or a DCCH and / or DTCH are ensured to be received. The MAC PDU of the invention supports a new flexible multiplex mode on the situation of enhanced CELL_FACH, thus allowing the UE to realize supporting HSDPA technique very well on the situation of enhanced CELL_FACH and ensuring the realization of HSDPA.

Description

technical field [0001] The present invention relates, in particular, to a method for realizing high-speed downlink packet access (HSDPA) under an enhanced CELL_FACH state in FDD (Enhanced CELL_FACH state in FDD). [0002] For the convenience of description herein, the enhanced CELL_FACH state in frequency division duplexing is referred to as the enhanced CELL_FACH state for short. Background technique [0003] The Universal Mobile Telecommunications System (UMTS) is a third-generation wireless communication network technology standard defined by the Third Generation Partnership Project (3GPP). The UMTS network consists of subsystems such as the core network (Core Network) and the UMTS Terrestrial Radio Access Network (UTRAN, UMTS Terrestrial Radio Access Network), such as figure 1 as shown, figure 1 It is a schematic diagram of the network structure of UMTS. In UTRAN, the interface between the Node B (NodeB) and the radio network controller (RNC) is the Iub interface, the ...
