  • Patent number: 9391765
    Abstract: Aspects of a method and system for 60 GHz wireless clock distribution may include configuring a microwave communication link established between a first chip and a second chip via a wireline communication bus. The configuration may comprise adjusting beamforming parameters of a first antenna array communicatively coupled to the first chip, and of a second antenna array communicatively coupled to the second chip. The first chip and the second chip may communicate a clock signal via said microwave communication link. The microwave communication link may be routed via one or more relay chips, when the first chip and the second chip cannot directly communicate. Control data may be transferred between the first chip, the second chip, and/or the one or more relay chips, which may comprise one or more antennas. The relay chips may be dedicated relay ICs or multi-purpose transmitter/receivers.

  • Patent number: 9391870
    Abstract: Aspects of a method and system for symmetric transmit and receive latencies in an energy efficient PHY are provided. In this regard, a delay introduced by a PHY of a network device for outbound traffic and a delay introduced by the PHY for inbound traffic may be controlled such that a transmit delay of the network device is equal, within a tolerance, to a receive latency of the network device. The delays may be controlled based on whether one or more energy efficiency features are enabled in the PHY. The delay introduced by the PHY for outbound traffic may be controlled based on an amount of buffered inbound traffic. The delay introduced by the PHY for inbound traffic may be controlled based on an amount of buffered outbound traffic. The delays may be controlled such that said receive latency and the transmit latency are approximately constant regardless of a mode of operation of the network device.

  • Patent number: 9391170
    Abstract: A field-effect transistor (FET) on bulk substrate and a method of fabricating the same is discussed herein. The FET includes a dielectric layer disposed on the bulk substrate and a fin structure and a gate structure disposed on the dielectric layer. The dielectric layer includes alternating first and second dielectric regions. The fin structure includes a channel region interposed between a source region and a drain region. The gate structure is capacitively coupled to the fin structure and positioned between the source region and the drain region. Improved performance characteristics of FET is primarily achieved with the dielectric layer providing electrical isolation of the fin structure from the bulk substrate.

  • Publication number: 20160197658
    Abstract: In a base station having a Massive Multiple Input Multiple Output (M-MIMO) antenna array, the availability of the M-MIMO antenna array is exploited to manage the interference caused by the base station to neighboring cells. In one embodiment, the large number of antenna elements of the M-MIMO antenna array are used to create precise transmit and/or receive spatial nulls at specific User Equipments (UEs) being served by a neighboring cell and/or in select areas of the neighboring cell. Depending on whether the spatial null is partial or full, transmissions by the base station may have reduced or even zero receive power within the neighboring cell.

  • Patent number: 9386566
    Abstract: A user equipment (UE) has established a first radio link with a serving network node and a second device-to-device (D2D) radio link directly with another user equipment (UE). In response to having D2D data to send to the other UE over the D2D radio link, the UE sends to the serving network node on the first link a request for radio resources for a layer 1 (L1) control channel; and in response to an assignment of D2D resources by the serving network node in reply to that request, the UE sends on the assigned D2D resources to the other UE the D2D data and the L1 control channel. In one example the request includes an indication of the UE's link adaptation for the L1 control channel such as format for a PDCCH or ePDCCH and/or aggregation level.

  • Publication number: 20160190057
    Abstract: Various examples are provided for interconnection structures for molded IC packages. In one example, among others, an IC package includes a substrate and an interposer. A plurality of conductive elements provide physical and electrical contact between a surface of the substrate and a surface of the interposer. A standoff element disposed between the surfaces of the substrate and interposer provides a minimum spacing between the surfaces of the substrate and interposer. In some implementations, a standoff element is disposed between an IC die disposed on the surface of the substrate and the surface of the interposer. In another example, a method includes coupling conductive elements to a surface of an interposer, attaching a standoff element, coupling the conductive elements to a surface of a substrate, and forming an embedded layer between the interposer and substrate. The standoff element defines a minimum gap between the interposer and the substrate.

  • Patent number: 9380337
    Abstract: Command packets for a personal video recorder that provides for a transport stream (TS) that contains data and also includes a transport packet (TP)/TS formatted command packets. The TP/TS formatted command packet may be communicated between any number of devices, including multiple chips, multiple boards, and multiple processors. A decoder is able to decode the TP/TS formatted command packet and to perform the appropriate operation on data portions of the TS. When a TS is provided to a device not having the capability to perform the proper decoding of the TP/TS formatted command packet, that particular packet may be deemed as being unidentified (or unknown) adaptation field data. Alternatively, the packet may be identified as being corrupted data and/or irrelevant data.

  • Patent number: 9379969
    Abstract: Aspects of a method and system for energy-efficiency-based packet classification are provided. In this regard, a network link for communicating a packet may be selected based, at least in part, on an amount of energy required to communicate the packet over the network link, and based, at least in part, on an energy efficiency class to which the packet is assigned. The energy efficiency class may be determined based on one or more fields of the packet, wherein the fields may comprise one or more of an Ethertype field, a type of service header of an IP datagram, and a field pre-pended or appended to a payload of the packet. In this regard, during or subsequent to generation of the packet, the packet may be marked such that a network path traversed by the generated packet may be determined based on the energy required to communicate the packet over the network path.

  • Patent number: 9379790
    Abstract: In wireless operating environments, wireless user devices are often within the coverage area of multiple base stations. The base station providing the best uplink for the user device may be different than the base station providing the best downlink for the user device. Systems and techniques for asymmetric uplink and downlink communications for a user device are provided. In embodiments, the user device initially synchronizes with a base station. Both the uplink and downlink are initially served by this base station. A determination is then made whether to handoff the downlink for the user device to another base station. When a determination is indicated, the downlink is handed off to the second base station. Thereafter, periodic measurements are made. The determinations whether to handoff the uplink and downlink for the user device are made independently.
