Abstract: The present disclosure belongs to the field of communications and more particularly relates to a decentralized trusted access method for a cellular base station. The method includes: uploading registration information to a blockchain network to add the cellular base station as a member to the blockchain network; uploading a master information block to the blockchain network, receiving block identification information from the blockchain network; broadcasting the master information block and the block identification information to cellular users within the coverage area; receiving an access request from the cellular user, and in response to the access request, performing uplink synchronization with the cellular user issuing the access request based on a random access procedure.

Abstract: Embodiments of the present disclosure may provide a service transmission method and device. The service transmission method may include: determining, by a user terminal, whether a service of the user terminal is a service needing global cooperation; transmitting, by the user terminal, the service with a global Base Band Unit (BBU) pool mode if the service of the user terminal is the service needing the global cooperation; and transmitting, by the user terminal, the service with a non-global BBU pool mode if the service of the user terminal is the service, which does not need the global cooperation.

Abstract translation: 本公开的实施例可以提供服务传输方法和设备。 服务发送方法可以包括：由用户终端确定用户终端的服务是否是需要全球合作的服务; 如果用户终端的服务是需要全球合作的服务，则由用户终端发送具有全局基带单元（BBU）池模式的业务; 并且如果用户终端的服务是不需要全局协作的服务，则由用户终端发送具有非全局BBU池模式的服务。

Abstract: In a network comprising a plurality of macro base stations, a plurality of micro base stations and a plurality of user devices (UEs), a method of establishing a wireless communication network includes: assigning the micro base stations into a plurality of clusters and selecting a micro base station from each of the clusters as a cluster head; receiving, from cluster heads of the clusters by the network device, information about candidate sub-clusters determined by UEs, each of the candidate sub-clusters comprises micro base stations whose signal power received at a UE exceeds a pre-defined threshold; identifying at least two schemes of grouping the micro base stations into non-overlapping sub-clusters based on the candidate sub-clusters; for a scheme of the at least two schemes, making each of the UEs select to access a macro base station or to be associated with one of the non-overlapping sub-clusters of the scheme base on respective measurements of signals received from at least one of a macro base station and a sub-cluster of the non-overlapping sub-clusters of the scheme; suppressing, by a UE, inter-symbol interference by subtracting a tail of a first symbol from a second symbol before recovering the second symbol; suppressing, by the UE, inter-carrier interference by adding a tail estimated of the second symbol to the second symbol before recovering the second symbol; acquiring information about power consumption of each of the macro base stations and power consumption of each of the micro base stations in communications with the UEs which performs inter-symbol interference suppression and inter-carrier interference suppression at the UEs; and making the micro base stations perform joint transmissions in sub-clusters as specified in a scheme selected from the at least two schemes according to the information about power consumption.

Abstract: A method and system for monitoring and processing a wireless signal are described. The method includes, if an authorized base station/Access Point (AP) receives a first abnormal signal from the terminal, which is identified as an unauthorized signal by a terminal, processing, by the authorized base station/AP, the first abnormal signal. If the authorized base station/Access Point (AP) receives a second abnormal signal from the terminal and the terminal cannot determine whether the second abnormal signal is the unauthorized signal or an authorized signal, identifying, by the authorized base station/AP, characteristics of the second signal and processing the second abnormal signal if the second abnormal signal is the unauthorized signal.
