20140269267 | METHODS FOR DYNAMIC TRANSCEIVER RESOURCE ALLOCATION IN MULTI-TRANSCEIVER SYSTEMS - Embodiments of a system and method for managing transceiver resources in a wireless network are generally described herein. In some embodiments, a transceiver resource manager (MXRM) dynamically adapts the number of transceivers to an offered load. A node computes the number of transceiver it needs based on queue depth and queue usage. MXRM then shares the number of the transceivers to be requested, A, with next-hop neighbors. A node assigns X transceivers such that X is the maximum of their own A value and the highest A value they receive if they are next-hop targets. MXRM processes requests for additional transceivers from nodes and previous-hop neighbors such that the sender-receiver pair assigns a compatible number of transceivers. MXRM is also used to drive frequency assignments to increase capacity along the traffic flows. Therefore, MXRM adapts transceiver assignments to the traffic paths. | 2014-09-18 |

20140269365 | SYSTEM AND METHOD FOR TESTING A DATA PACKET SIGNAL TRANSCEIVER - A system and method for testing signal reception by a data packet signal transceiver. By monitoring signals provided to and returning from a device under test (DUT), e.g., stimulus and response signals, respectively, it can be determined whether and when the DUT has received a faulty data packet or received a valid data packet in a faulty manner. When such events occur, appropriate control signals are provided for instructing the test signal reception and analysis subsystem (e.g., a vector signal analyzer) to capture and retain for analysis such faulty data packet or valid data packet received in a faulty manner. This enables the data packet reception test results to identify the number of data packets correctly received within the prescribed time interval and identify which data packet reception faults are due to reception of a faulty data packet or reception of a valid data packet in a faulty manner. | 2014-09-18 |
