Power control method and device
The present invention relates to the field of wireless communications, and in particular, to a transmit power control technology in a wireless communications system. In a transmit power control method, user equipment performs transmit power compensation on subframes in different subframe sets by using different power compensation amounts, and sends data in the subframes by using uplink transmit powers on which the transmit power compensation has been performed. According to the solution provided in this application, smoothness of a signal-to-noise ratio of each uplink subframe can be ensured when a full-duplex technology is applied, and reception performance of the uplink subframe can further be ensured without causing excessively large signaling overheads.
Managing network packet communication simultaneously through wired and wireless network interfaces
A client information handling system application selectively communicates network packets simultaneously through plural network interfaces by leveraging network address translation at the network layer of the network packets. Network packets are distributed across the plural network interfaces to achieve desired network communication goals, such as bandwidth, data rates, quality of service, reliability and SAR requirements.
METHOD AND DEVICE FOR OPERATING A BATTERY-OPERATED SMART METERING METER
A method and a device are used during battery operation of a smart metering meter equipped with a consumption sensor and a transmit clock generator for a radio module for transmitting consumption data packets, in the event of a decreased residual capacity of the battery, to determine if the data packets can be transmitted as previously with the residual capacity over the residual time period until a scheduled battery exchange at the end of a specified operating time period. If not, the transmit power, for example, of the data packets is reduced and/or their transmit clock is extended over the residual period. This determination, along with a control specification, are preferably performed in a concentrator and are transmitted to the meter by using bidirectionally operating radio modules so that computer capacities required therefor need not be retained in each individual meter of a supply area.
Combined open loop/closed loop (CQI-based) uplink transmit power control with interference mitigation for E-UTRA
A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.
Method and arrangement for reducing power consumption in a mobile communication network
The invention relates to a method and an arrangement for reducing power consumption of a receiver in a mobile communication network comprising a sender transmitting packet data on a downlink channel to one or more receivers over a radio interface. Inactive time instants and listening time instants are defined according to provided rules. The receiver is arranged to listen for information from the sender during the listening time instants and to sleep during the inactive time instants. Thus, less power will be consumed during the inactive time instants.
Radio resource management for a high-speed shared channel
Radio resources like spreading codes and transmission power are optimally allocated to various different types of radio channels supported in the cell including a specialized channel like a high-speed shared channel. One or more measurements made at the base station are provided to the radio resource manager. Such measurements include other-channel power, high speed shared channel code usage, high speed shared channel transport format usage, average active load on the high speed shared channel, empty buffer, excess power, and similar parameters that relate to a high speed shared channel. One or more of these reported measurements may then be used to access, allocate, and/or to regulate resources associated with the base station's cell.
Uplink power control method and apparatus
Embodiments of the present disclosure provide an uplink power control method, includes: determining, by a base station, power control information, where the power control information is used to control a power of a UE; sending, by the base station, hybrid automatic repeat request (HARQ) acknowledgment feedback information to X UEs, where the HARQ acknowledgment feedback information carries the power control information of at least one of the X UEs, the X UEs contend for use of a same transmission resource, and X is an integer greater than or equal to 1; receiving, by the UE, acknowledgment feedback information sent by the base station to the X UEs; and parsing the HARQ acknowledgment feedback information; and if it is determined that the HARQ acknowledgment feedback information includes the power control information of the UE, performing power control on the user equipment based on the power control information of the UE.
PROGRAM FOR ADJUSTING CHANNEL INTERFERENCE BETWEEN ACCESS POINTS IN A WIRELESS NETWORK
The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.
