20120034948 | METHOD, DEVICE, AND SYSTEM FOR REGULATING POWER CONSUMPTION - A method, device and system for regulating power consumption are provided in the embodiments of the present invention. A method for regulating power consumption includes: obtaining, by a base station, an application point and a configuration parameter; sending, by the base station, an indication message to a terminal according to the application point and configuration parameter; regulating, by the base station, the power consumption of the base station by using the configuration parameter at the application point; the configuration parameter comprises cell antenna information or system bandwidth information; the indication message instructs the terminal to use the configuration parameter at the application point. Under the condition that user's normal communication is remained, the number of cell antennas or the cell bandwidth is dynamically changed so that the number of a downstream reference signal is dynamically adjusted. This reduces the power consumption of the network device. | 02-09-2012 |
20120282969 | Method, Device, and System for Determining Timing Advance Grouping - Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping, and relate to the field of communications. A base station (eNodeB) adds a component carrier (CC) for a user equipment (UE). According to obtained timing advance (TA) group information or a preset rule, a TA group that the added CC belongs to is determined. The TA group is a set of CCs that can share a TA. Identification information that identifies the TA group to the UE is sent. | 11-08-2012 |
20140128069 | Method, User Equipment, and Base Station for Changing Access Cell - The present invention discloses a method, a user equipment, and a base station for changing an access cell. According to the method, the user equipment, and the base station in the embodiments of the present invention, when the UE leaves the coverage of the first radio network and the UE is in the dual-camped state, the first cell of the first radio network that the UE currently accesses is changed to the second cell of the second radio network that the UE currently accesses, so as to avoid a cell change failure caused by an incorrect target cell during cell reselection or handover, thereby accurately changing an access cell, reducing network delay, and improving user experience. | 05-08-2014 |
20140153474 | METHOD, BASE STATION AND SYSTEM FOR RESELECTION OR HANDOVER TO BROADCAST MULTICAST CELL - The present invention discloses a method and system for reselecting or handing over to a broadcast multicast cell. The method includes the following steps: broadcasting, by an MBMS cell, a service area identity list of a service area to which the MBMS cell belongs; determining, by a UE, whether the service area identity list includes a service area identity corresponding to a service; if the service area identity list includes service area identity corresponding to the service, setting, by the UE, a cell reselection priority of a frequency of an MBMS cell to the highest. According to the present invention, a UE can identify whether a cell capable of providing services that the UE is receiving or is interested in around the UE, so that the cell can learn which neighboring cells are MBMS cells and what services are being broadcast in MBMS cells if such MBMS cells are available. | 06-05-2014 |
20140153475 | Method, Apparatus, and System for Transmission Control of Multimedia Broadcast Multicast Service Data - Embodiments of the present invention disclose a method, an apparatus, and a system for transmission control of multimedia broadcast multicast data. The method includes: according to a reference time, determining a scheduling period of suspending or resuming sending MBMS service data; and suspending or resuming sending the MBMS service data in the determined scheduling period. According to the embodiments of the present invention, transmission control of the MBMS service data by a base station can be realized, which facilitates each base station in the same MBSFA range synchronously suspending or resuming sending the MBMS service data of the same service, thereby facilitating reducing interferences in the service | 06-05-2014 |
20140274196 | DEVICE-TO-DEVICE (D2D) POWER CONTROL METHOD, USER EQUIPMENT, BASE STATION, AND COMMUNICATION SYSTEM - Embodiments of the present invention provide a device-to-device (D2D) power control method, a user equipment, a base station, and a communication system. The method includes: receiving, by a first user equipment UE, path loss information sent by a base station or a reference signal sent by a second UE, and obtaining a transmit power of the first UE according to the path loss information or the reference signal; sending data to the second UE based on the transmit power of the first UE, so that the second UE obtains an adjustment reference value according to the data and sends detection control information to the base station according to the adjustment reference value; and receiving, by the first UE, power adjustment information which is sent by the base station according to the detection control information, and adjusting, according to the power adjustment information, the transmit power of the first UE. | 09-18-2014 |
