Embodiment Construction
[0054] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0055] refer to figure 2 , figure 2 It is a schematic flowchart of the first embodiment of the macro-diversity data adaptive processing method of the present invention. Such as figure 2 As shown, the macro-diversity data adaptive processing method of the present invention comprises the following steps:
[0056] Step S01, extract the data packets that first arrive at RNC through different Iubs and have correct CRC, and store the data packets;
[0057] For macro-diversity user data packets, when arriving at RNC through different Iub transmissions, extract the data packets that arrive at RNC first and have correct CRC, and put the data packets into preset register...

The invention discloses a self-adaptive processing method for macrodiversity data. The method comprises the following steps: extracting a same data packet which is firstly arrived at an RNC through different Iubs and a CRC is right and storing the data packet; recording time difference of arrival time when the data packet respectively arrives at the RNC from any two different base stations; and based on the time difference and an initial uplink reception time window, adjusting a current uplink reception time window. The invention also discloses a self-adaptive processing device for the macrodiversity data. Through recoding time difference of arrival time when the CRC-correct same data packet respectively arrives at the RNC from any two different base stations and adjusting the current uplink reception time window based on the time difference and the initial uplink reception time window, the advantages that combined with macrodiversity, different base station Iub transmission delay is processed, and the data merging processing uplink reception time window is self-adaptively adjusted are achieved, therefore, the problem that the data packet which arrives later due to the Iub transmission delay but of which the CRC is correct is discarded because the merging processing time is exceeded is prevented.
Description
technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for adaptively processing macro-diversity data. Background technique [0002] The wireless mobile network brings people the convenience of enjoying information and Internet services anytime and anywhere. UMTS (Universal Mobile Telecommunications Systems, universal mobile communication system) is a third generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) air interface technology. Therefore the UMTS system is also commonly referred to as the WCDMA system. The WCDMA system consists of the following network elements: UE (UserEquipment, user terminal equipment), UTRAN (UMTSTerrestrialRadioAccessNetworkUMTS, terrestrial wireless access network) and CN (CoreNetwork, core network). Among them, the UTRAN completes the relevant functions of wireless side processing, a...
