20140139401 | PHASE SHIFTING APPARATUS AND ANTENNA SYSTEM TO WHICH PHASE SHIFTING APPARATUS IS APPLIED - Embodiments of the present invention disclose a phase shifting apparatus, including a first conductor section, a first tapping element, a feeder unit, and a dielectric element, where: the feeder unit is electrically connected to the first tapping element; the first tapping element is electrically connected to the first conductor section; the first tapping element is capable of moving along the first conductor section to change a phase of a signal that flows through the feeder unit, the first tapping element, and the first conductor section; and the dielectric element is disposed at a position near the first conductor section. With the phase shifting apparatus in the embodiments of the present invention, the dielectric element is disposed in order to increase an electrical length of a conductor, which correspondingly reduces a physical length of the conductor, so that the size of the phase shifting apparatus is reduced. | 05-22-2014 |
20110207498 | Resource Configuration Method, Device, and System - A resource configuration method includes acquiring capability information of a base station (BS), in which the capability information of the BS includes information indicating whether the BS has channel power boost capability. Capability information of a user equipment (UE) is acquired. The capability information of the UE includes information indicating whether the UE has the channel power boost capability. The BS is notified to configure resources for performing channel estimation by using the channel power boost capability for the UE if the UE and the BS both have the channel power boost capability. | 08-25-2011 |
20090044257 | METHOD AND SYSTEM FOR ASSIGNING HOME AGENT - The invention discloses a method and system for assigning a home agent, and the method includes: indicating, by a visited network, to a home network that the visited network supports the home agent assignment; receiving, by the visited network, authorization information from the home network, the authorization information indicates the visited network is authorized for assigning the home agent; and sending, by the visited network, information about an address of the home agent to a mobile node. The invention can remedy the drawback that the home agent can be assigned to the mobile node only in the home network, thus improving the communication efficiency and reducing the delay. Further, an effective control can be enforced on assignment, so that the visited network can indicate to the home network whether it can support assigning of the home agent, and the home network can enforce a control on whether to perform assignment in the visited network. | 02-12-2009 |
