  • Patent number: 9979756
    Abstract: A user device registers with a proxy-call session control function device (P-CSCF) associated with an Internet protocol (IP) multimedia subsystem (IMS). The user device forwards a request to the P-CSCF requesting a session via the IMS for an IMS call. If a response to the request is not received from the P-CSCF during a time period after forwarding the request, the user device attempts to newly register with the P-CSCF. If the new registration is successful, the user device re-forwards the request to the P-CSCF. Otherwise, if the new registration with the P-CSCF is unsuccessful, the user device registers with a different P-CSCF and forwards the request to the second P-CSCF.

  • Patent number: 9974060
    Abstract: Methods, base stations and access terminals for uplink signalling are provided. Resource request channel characteristics such as location in time-frequency, sequence, time slot, are assigned to each access terminal to distinguish their resource requests from the resource requests of other access terminals. Access terminals make requests using a resource request on a resource request channel having the assigned characteristics. The base station can then determine which access terminal transmitted the resource request based on the resource request channel characteristics of the resource request channel upon which the resource request was received. The base station then transmits a response to the request which may for example be a new resource allocation, a default allocation or a renewal of a previous allocation.

  • Publication number: 20180082846
    Abstract: Multigate devices and fabrication methods that mitigate the layout effects are described. In conventional processes to fabricate multigate semiconductor devices such as FinFET devices, long isolation cut masks may be used. This can lead to undesirable layout effects. To mitigate or eliminate the layout effect, fabrication methods are proposed in which the interlayer dielectric (ILD) layer remains intact at the gate cut location during the fabrication process.

  • Publication number: 20180076197
    Abstract: Semiconductor devices employing Field Effect Transistors (FETs) with multiple channel structures without shallow trench isolation (STI) void-induced electrical shorts are disclosed. In one aspect, a semiconductor device is provided that includes a substrate. The semiconductor device includes channel structures disposed over the substrate, the channel structures corresponding to a FET. An STI trench is formed between each corresponding pair of channel structures. Each STI trench includes a bottom region filled with a lower quality oxide, and a top region filled with a higher quality oxide. The lower quality oxide is susceptible to void formation in the bottom region during particular fabrication steps of the semiconductor device. However, the higher quality oxide is not susceptible to void formation. Thus, the higher quality oxide does not include voids with which a gate may electrically couple to other active components, thus preventing STI void-induced electrical shorts in the semiconductor device.

  • Publication number: 20180058943
    Abstract: Middle-of-line (MOL) metal resistor temperature sensors for localized temperature sensing of active semiconductor areas in integrated circuits (ICs) are disclosed. One or more metal resistors are fabricated in a MOL layer in the IC adjacent to an active semiconductor area to sense ambient temperature in the adjacent active semiconductor area. Voltage of the metal resistor will change as a function of ambient temperature of the metal resistor, which can be sensed to measure the ambient temperature around devices in the active semiconductor layer adjacent to the metal resistor. By fabricating a metal resistor in the MOL layer, the metal resistor can be localized adjacent and close to semiconductor devices to more accurately sense ambient temperature of the semiconductor devices. The same fabrication processes used to create contacts in the MOL layer can be used to fabricate the metal resistor.

  • Publication number: 20180027558
    Abstract: A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection.
