Patent number: 9722764Abstract: Embodiments provide solutions to reduce power utilization (either at individual cable modems or in the overall network) in future cable modem networks. Particularly, embodiments seek to reduce power utilization at individual cable modems and in the overall network, by allocating upstream frequency bands and/or transmission modulation schemes among cable modems while accounting for cable loss experienced by individual upstream cable modem transmissions. According to embodiments, frequency spectrum and modulation scheme allocation techniques are provided to optimize power utilization and enable lower upstream transmission power by cable modems while maintaining similar signal strength of received signals or lower signal strength with reduced SNR requirements using lower capacity modulation at the headend.Type: GrantFiled: April 15, 2014Date of Patent: August 1, 2017Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 9049725Abstract: A spread spectrum communication system includes a base station that is able to transmit wireless signals that are spread by any of a plurality of orthogonal spreading codes and receive wireless signals that mobile stations transmit in an access channel. One of the orthogonal spreading codes is reserved as an indicator code that the base station uses to indicate when the access channel is occupied by a transmission from a mobile station. When the base station detects a transmission in the access channel, the base station estimates a completion time when the transmission will be completed and transmits an indicator signal spread with the indicator code until the completion time is reached. Before a mobile station transmits a message in the access channel, the mobile station determines whether the access channel is occupied by determining whether the base station is transmitting the indicator signal.Type: GrantFiled: October 9, 2009Date of Patent: June 2, 2015Assignee: Sprint Spectrum L.P.Inventors: Bhagwan Khanka, Manoj Shetty, Sachin R.

Patent number: 9031054Abstract: In one embodiment, in absence of transmitting from an apparatus a reservation request frame, the apparatus receives a reservation response frame on an assigned channel. The reservation response frame indicates a duration of a frame transmission. In response to receiving the reservation response frame, the apparatus transmits a frame on the assigned channel during the frame transmission. In another embodiment, in response to receiving a reservation request frame on a first channel at an apparatus, the apparatus transmits a reservation response frame on the first channel and on at least one second channel. The reservation request frame indicates a duration of a frame transmission. The reservation response frame indicates the duration of the frame transmission. After transmitting the reservation response frame, this apparatus receives during the frame transmission a first frame on the primary channel and a second frame on the at least one secondary channel.Type: GrantFiled: July 9, 2010Date of Patent: May 12, 2015Assignee: Nokia CorporationInventors: Janne Marin, Mika Kasslin, Jarkko Kneckt
