20100330900 | DIGITAL RADIO BROADCAST TRANSMISSION USING A TABLE OF CONTENTS - For each audio and data service, a table of contents (TOC) specifies which logical channel may carry data. The TOC may be transmitted over the NRSC-5 transmission system using a pre-defined protocol, which is received and decoded at an NRSC-5 receiver apparatus that extracts the TOC. When a user or an application requests a specific service from the receiver, the receiver logic may examine the TOC and may identify which LC may carry the requested service data. The receiver may only decode the LCs that are needed for the requested service, and may not decode other unneeded LCs thereby conserving power and memory. | 12-30-2010 |

20130230088 | ANTENNA POINTING FOR MULTIPLE-INPUT-MULTIPLE-OUT (MIMO) DEVICES - Performance in multiple-input-multiple-output (MIMO) antenna systems may be enhanced by configuring beams in a direction that reduces coupling between the beams. A decoupling metric may be calculated based on signal strengths received through the beams when an antenna system is pointed in different directions. The decoupling metric may be used to select a particular direction for operation of the antenna system. The decoupling metric may be combined with the signal strengths from each beam to select a direction for the antenna. An interface provides information to a user during positioning of the antenna to allow the user to select a direction for placement of the antenna that reduces coupling between beams in the MIMO antenna system. | 09-05-2013 |
20140064077 | OPPORTUNISTIC WIRELESS RESOURCE UTILIZATION USING DYNAMIC TRAFFIC SHAPING - Systems and methods which provide resource sharing techniques implementing opportunistic shared resource utilization using dynamic traffic shaping are disclosed. Embodiments implement a multi-part transmission frame generation process in which data packets of various different traffic flows are selected for the transmission frame to fill the frame capacity. For example, scheduling logic may apply traffic shaping logic to select data packet queues from which data packets are to be included in a frame and to initially determine a number of packets to be included in the frame from each selected data packet queue according to the traffic shaping logic. Thereafter, the frame may be analyzed to determine if excess capacity remains. The scheduling logic may then apply traffic shaping logic to the data packet queues to implement an opportunistic scheme for including additional data packets in the frame and thereby fill the excess capacity. | 03-06-2014 |

Alternatively, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on the bandwidth needs of each respective buffer being allocated. Alternatively still, buffer space may be dynamically allocated without impeding other resource allocation by basing the buffer space allocation at least on a function of the traffic priority class that each allocated buffer will handle and the bandwidth needs of each respective buffer being allocated. | 12-11-2014 |
