20160057055 | BINDING IEEE 802.11 MAC FRAMES TO LOGICAL CHANNELS - An IEEE 802.11 media access control (MAC) frame (or contents thereof) at a transmitter apparatus includes information from which a logical channel carrying traffic can be identified, so that a receiver apparatus, when unpacking the IEEE 802.11 MAC frame (or contents thereof), is able to route the traffic to the appropriate radio link control (RLC) entity associated with the logical channel. An evolved Node B (eNB) that is also an access point (AP) distinguishes conventional uplink wireless local area network (WLAN) traffic from traffic that is to be routed to an RLC layer. | 02-25-2016 |
20160073265 | Method and Apparatus for Authenticating a Network Entity Using Unlicensed Wireless Spectrum - An unlicensed wireless spectrum access point control circuit receives a first identifier from a first network entity and also receives a second identifier from a second network entity and then compares the late the first identifier to the second identifier to thereby authenticate the second network entity. By one approach the first and second identifier are medium access control (MAC) addresses. By one approach the first network entity comprises an Evolved Node-B base station in a Long Term Evolution (LTE) Radio Access Network and the second network entity comprises a portable wireless device. Upon authenticating the second network entity, the control circuit can then allow user plane data traffic. | 03-10-2016 |
20160073404 | Method and Apparatus for Simultaneous Use of Both Licensed and Unlicensed Wireless Spectrum - A control circuit determines that a wireless portable electronic device currently being serviced via licensed wireless spectrum should also be served via unlicensed wireless spectrum and then transmits a Radio Resource Control (RRC) message to cause the wireless portable electronic device to connect to a network node operating in the unlicensed wireless spectrum. By one approach this control circuit comprises an Evolved Node-B base station in a Long Term Evolution (LTE) Radio Access Network (RAN) and the network node operating in the unlicensed wireless spectrum comprises an 802.11-compatible wireless local area network node. | 03-10-2016 |
20160073428 | Method and Apparatus to Determine a Pseudo-Grant Size for Data to be Transmitted - A control circuit determines a pseudo-grant size for data to be transmitted via an unlicensed wireless spectrum. This pseudo-grant size indicates to a protocol layer above a medium access control protocol layer an amount of data that can be transmitted in a transmission instance over the unlicensed wireless spectrum. By one approach the control circuit can then transmit an amount of data of that pseudo-grant size in the transmission instance over the unlicensed wireless spectrum. By one approach the pseudo-grant size comprises a static value. By another approach the pseudo-grant size comprises a dynamically-calculated value. | 03-10-2016 |
20160113029 | SCHEDULING AND COORDINATION IN A WIRELESS NETWORK - A network device may determine channel quality of a radio channel in a wireless network based on information from a user equipment (UE). Assistance information may provide channel conditions at a first network device. Orthogonal frequency division multiplexing (OFDM) streams based on the received assistance information and the channel quality may be dynamically scheduled. The network device may send to the first network device assistance information to cause scheduling adjustments. The sent assistance information may provide channel conditions in relation to the network device. | 04-21-2016 |

20160057824 | SOLID-STATE LIGHTING FIXTURE WITH COMPOUND SEMICONDUCTOR DRIVER CIRCUITRY - A lighting fixture includes a solid-state light source and driver circuitry. The solid-state light source includes at least one light emitting diode (LED). The driver circuitry includes one or more silicon carbide (SiC) switching components, and is coupled to the solid-state light source. Further, the driver circuitry is configured to receive an alternating current (AC) input voltage and generate a driver output current for driving the at least one LED from the AC input voltage. By using silicon carbide (SiC) for the switching components in the driver circuitry, the efficiency of the driver circuitry and thus the lighting fixture may be significantly increased, while simultaneously reducing the cost and complexity of the driver circuitry and thus the lighting fixture when compared to conventional lighting fixtures. | 02-25-2016 |
20160057825 | HIGH EFFICIENCY DRIVER CIRCUITRY FOR A SOLID STATE LIGHTING FIXTURE - Driver circuitry is coupled between a power supply and at least one LED in a solid-state lighting fixture, such that a non-isolated direct current (DC) path exists between the power supply and the at least one LED. The driver circuitry is configured to receive an AC input voltage and generate a driver output current for driving the at least one LED from the AC input voltage. By using driver circuitry that is non-isolated from the at least one LED in the solid-state lighting fixture, the efficiency of the driver circuitry may be increased, while simultaneously reducing the cost and complexity of the driver circuitry compared to conventional driver circuitry. | 02-25-2016 |
