Problems solved by technology
Since the primary and secondary carriers between adjacent cells are different, for example, the primary carrier of the serving cell may be the secondary carrier of the adjacent cell, and there may be no common downlink channel on the secondary carrier, in this case, the UE will not be able to directly measure the relative The interference of neighboring cells on the carrier, and how to measure and report the information of each carrier to the UE has not been proposed yet.

Embodiment Construction
[0036] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0037]In the multi-carrier HSUPA according to the related art, no matter whether the SNPL value of each carrier is reported independently by each carrier or the SNPL value of each carrier is reported on one carrier, the UE must report the path loss of the primary carrier or secondary carrier of the adjacent cell.
[0038] In the current multi-carrier protocol, the primary carrier between adjacent cells may be different, and there may be no downlink common channel on the secondary carrier. Therefore, the following two situations will occur:
[0039] (1) The UE supports multiple carriers, but the UE may not be able to directly measure the path loss of the auxiliary carrier of the adjacent cell, because the auxiliary carrier in the current multi-carrier protocol may not have the downlink common channel required by the UE to measure the path loss; (2) the UE ...

A multicarrier enlargement upstream access system neighbour district interference measuring method, comprises: step s202: wireless network controller allocating a supportable amount of carrierwaves for NodeB and subscriber equipment and allocating dominant carrierwave frequency point marks, subsidiary carrierwave frequency point marks of service district of subscriber equipment required for measuring and reporting and neighbour district of the service district and path-loss correction parameters of the service district and neighbour district for subscriber equipment; step s204, wireless network controller sending dominant carrierwave frequency point marks, subsidiary carrierwave frequency point marks and path-loss correction parameters of the service district and neighbour district to subscriber equipment; step s206, subscriber equipment measuring dominant carrierwave path-loss of service district based on dominant carrierwave frequency point marks, subsidiary carrierwave frequency point marks and path-loss correction parameters, and calculating subsidiary carrierwave path-loss of service district, and measuring dominant carrierwave path-loss of neighbour district and calculating subsidiary carrierwave path-loss of neighbour district.
Description
technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for measuring the interference of neighboring cells in a multi-carrier enhanced uplink access system. Background technique [0002] The enhanced uplink access system is generally called the High Speed Uplink Packet Access (HSUPA) system, and its purpose is to improve the efficiency of the uplink through advanced technology, thereby effectively supporting web browsing, video, multimedia information, and Other IP-based services. [0003] Currently, the 3rd Generation Partnership Project (3GPP) has completed the standardization of Time Division Synchronous Code Division Multiple Access (TD-SCDMA) enhanced uplink access system. The system is suitable for single carrier TD-SCDMA system. In the enhanced uplink (EUL), a new transmission channel is added, that is, the enhanced uplink dedicated transmission channel (E-DCH), the enhanced uplink data is carried on...
