Abstract
1. A mobile communication system comprising a plurality of base stations that perform radio communication with user equipment and a radio network controller which controls a plurality of base stations, wherein: the above radio network controller indicates the low frequency resource that is a radio resource for transmitting a reference signal to the aforementioned user equipment for power measuring less frequently than usual against the above base station, the aforementioned base station indicates to a complement to the low-frequency resource specified above radio network controller, a low-frequency resource, which is a radio resource for transmitting the aforementioned reference signal to the above UE, less frequently than usual ivysheupomyanutaya base station transmits the aforementioned reference signal to the above UE, less frequently than usual in the low frequency resource indicated above radio network controller, and low-frequency resource further designated stantsiey.2 itself above the base. The mobile communication system according to Claim. 1, in which the above base station notifies an adjacent base station of the low-frequency resource further indicated above base stantsiey.3 itself. The mobile communication system according to Claim. 1, in which the above base station notifies said radio network controller of the low-frequency resource further indicated above base stantsiey.4 itself. mobile communication system according to claim. 3, wherein the radio network controller aforementioned change

The UMTS base station router

TL;DR: This paper reviews the Alcatel-Lucent Universal Mobile Telecommunications System (UMTS) base station router (BSR)—a radio access network (RAN) and core network (CN) in a single network element which can be considered a wireless edge router that bridges between cellular-specific wireless transmissions and IP networks.

Assessment of Network Layouts for CDMA Radio Access

TL;DR: The obtained results of the numerical analysis indicate that a hexagonal "clover-leaf" layout is superior, but the results of system-level simulation give similar performance for the triangular and square layouts, which indicates also the importance of the antenna height optimization for all layouts.
