20110223957 | BASE STATION WITH IMPROVED CHANNEL QUALITY PREDICTION FOR WIRELESS COMMUNICATION - A base station with improved performance through channel quality prediction employing link adaption techniques including a receiver which makes selective measurements on downlink transmissions, and then stores one or more of the measurements or a channel quality indicator derived therefrom. The receiver then retrieves one or more of the past measurements (or the past channel quality estimates themselves), and combines it with current measurements (or the current channel quality estimate), to predict what the channel quality will be at some future time and derive a predictive channel quality indicator (CQI). This predictive CQI, derived from both current channel measurements and at least one past channel measurement, is then sent to the transmitter for use in updating transmission parameters. | 09-15-2011 |
20110319114 | METHOD AND APPARATUS FOR USING AND/OR IMPLEMENTING CONTROL CHANNELS IN WHITE SPACE - Methods and apparatus related to control channels in a wireless communications system are described. Different white space bands may be available at different locations. A wireless terminal monitors control information from multiple potentially available communications channels. Control time slots corresponding to some different channels are intentionally time offset from one another. Some embodiments implement predetermined control slot timing synchronized with respect to an external timing source. In other embodiments, a wireless terminal selects a control time slot on a new channel as a function of control slot timing on channels already in use. A wireless terminal selects one of a plurality of communications channels for use in communicating information and determines a position of a control time slot to be used on the selected communications channels. The wireless terminal uses the control time slot on the selected communications channel to transmit and receive control information. | 12-29-2011 |
20110319115 | SYSTEM AND METHOD FOR MANAGING UE-BASED NETWORK PERFORMANCE MEASUREMENTS - A method and apparatus for managing UE-based network performance measurements utilizing a process of tracing a UE in a radio telecommunication network. An eNB may receive a trace activation message from a Mobility Management Entity, MME, or a Network Management Entity, wherein the trace activation message includes eNB-specific, and optionally MME-specific, selection conditions for selecting a UE for a trace session. The eNB selects a UE for tracing when the eNB-specific selection conditions are satisfied, and may send the MME-specific selection conditions to the MME for evaluation. When all selection conditions are satisfied, the eNB activates the trace session with the selected UE. The Trace Activation IE utilized in the Trace Start message, the UE Context Setup Request message, and the Handover Request message is extended with additional IEs in order to implement the method. | 12-29-2011 |

20130295980 | DETERMINING NOISE LEVELS IN FREQUENCY BAND(S) IN DISTRIBUTED ANTENNA SYSTEMS AND ADJUSTING FREQUENCY BAND(S) OF COMMUNICATIONS SIGNALS IN RESPONSE, AND RELATED COMPONENTS, SYSTEMS, AND METHODS - Determining noise levels in frequency band(s) for communications paths in distributed antenna systems. Noise may be induced in communications paths in distributed antenna system as a result of electromagnetic interference from communications media located in close proximity and/or from other electronic devices. Noise induced on communications media may not be evenly distributed across the frequency spectrum, but instead concentrated in certain portions of the frequency spectrum. The frequency band(s) of communication signals distributed in the distributed antenna systems may be adjusted to be provided outside of frequency band(s) having unacceptable noise levels. In this manner, the communications performance (e.g., the signal-to-noise (S/N) ratio) of communications signals communicated in the distributed antenna systems may be improved. | 11-07-2013 |
