Embodiment Construction

[0024] Advanced mobile networks (radio access networks) such as LTE, LTE-A and 5G compatible networks achieve high data rates in several ways, especially for coordinated signals from multiple sources.

[0025] External synchronization of the base stations is required in the mobile network so that signals transmitted by different antennas or different base stations complete phase alignment when they arrive at the UE. Some phase alignment errors are allowed, but too large errors will degrade service performance. We can consider that there is synchronization at the network element level and at the network level. At the network element level, the timing relationship of the transmission signal relative to the external timing signal can be controlled through sufficient equipment design, so that the delay is deterministic. At the network level, network engineering can be used to make the synchronization signal presented to the base station accurate to within a certain range.

Abstract

A remote radio head (RRH) of a distributed radio access network (RAN) is configured with user equipment (UE) co-located therewith. The UE may be a chipset integrated into the RRH, which is connected to other components of the RAN through a fronthaul network. The UE may be used to relay information, such as management information, to and / or from the RRH. The timing information obtained by the UE may be provided to the RRH and used as an indication of the fronthaul delay. The RRH may then adjust its operation according to the fronthaul delay indication.

Description

[0001] cross application [0002] This application claims the priority of the earlier application of U.S. Patent Application No. 15492044, filed on April 20, 2017, entitled "Remote Radio Frequency Head with User Equipment Terminal Capability", the content of which is incorporated by reference way incorporated into this article. technical field [0003] The invention relates to the communication field, in particular to the management and configuration of remote radio frequency head equipment. Background technique [0004] Wireless communication networks, such as fourth-generation (4G) mobile networks, fifth-generation (5G) mobile networks, etc., allow user equipment (User Equipment, referred to as UE) to communicate with each other and allow them to communicate through wireless access networks. (radioaccess network, RAN for short) infrastructure to communicate with other devices. A network meeting the Long Term Evolution (LTE for short) standard is considered to be an imple...
