20140241221 | METHOD FOR CHANNEL ASSIGNMENTS IN WIRELESS SYSTEMS - A wireless transmit/receive unit (WTRU) includes circuitry configured to receive first information from a wireless network, the first information indicating a first pattern of time intervals in which the WTRU is to monitor a plurality of control channels; not monitor the plurality of control channels in time intervals outside the first pattern of time intervals; and receive second information from the wireless network, the second information indicating a second pattern of time intervals in which the WTRU is to transmit control information on a control channel. | 08-28-2014 |
20140293876 | METHOD AND APPARATUS FOR STORING MOBILE STATION PHYSICAL MEASUREMENTS AND MAC PERFORMANCE STATISTICS IN A MANAGEMENT INFORMATION BASE OF AN ACCESS POINT - A method and apparatus may be used for exchanging measurements in wireless communications. The apparatus may receive a request. The request may be a measurement request, and may include a request for a measurement of a parameter. The apparatus may transmit a report. The report may be a measurement report, and may include the requested measurement of a parameter. The apparatus may store the requested measurement of the parameter in a management information base (MIB). | 10-02-2014 |
20140293933 | WIRELESS COMMUNICATION METHOD AND APPARATUS FOR REPORTING TRAFFIC VOLUME MEASUREMENT INFORMATION TO SUPPORT UPLINK DATA TRANSMISSIONS - A method and apparatus for uplink transmission is disclosed. A wireless transmit/receive unit (WTRU) transmits a message to a Node-B, wherein the message is selected from at least a first type, a second type, and a third type. The first type of message indicates that the WTRU has uplink buffered data to transmit and the WTRU requires uplink resources for transmission of uplink data. The second type of message includes a plurality of indications, wherein each indication indicates an amount of uplink buffered data associated with at least one logical channel, wherein each logical channel is associated with a priority. The third type of message indicates an amount of uplink buffered data and has less information than the second type of message. | 10-02-2014 |
20140328291 | MEDIUM ACCESS CONTROL LAYER ARCHITECTURE FOR SUPPORTING ENHANCED UPLINK - A method and apparatus for processing data is disclosed. A request for uplink resources is transmitted. An uplink scheduling grant is received in response to the request for uplink resources. Data from at least one medium access control for dedicated channel (MAC-d) flow is multiplexed into a medium access control for enhanced uplink (MAC-e) protocol data unit (PDU). A transport format combination (TFC) is selected for transmission of the MAC-e PDU, at least based on the uplink scheduling grant, a maximum allowed transmit power, and logical channel priority. A MAC-e PDU is transmitted over an enhanced uplink channel using a hybrid automatic repeat request (H-ARQ) process. | 11-06-2014 |
20150081803 | Recipient Control System for Ensuring Non-Conflicting and Comprehensive Distribution of Digital Information and Method Thereof - A system and method for ensuring an electronic communication sent by a user to one or more recipients is not sent to one or more inappropriate recipients. The system and method controls, monitors, detects and prevents sending of electronic communications to an unintended recipient or recipients. The system and method also controls, monitors, detects and ensures electronic communications are sent to all intended recipients. Based on parameters that identify conditions for an inappropriate recipient, the system and method compares each recipient of an electronic communication with the parameters and stops the sending if an inappropriate recipient exists. A notification is then provided identifying each inappropriate recipient and the parameters that were triggered. Mechanism to override the stopping of the electronic communication may be provided. | 03-19-2015 |
