  • Publication number: 20030086379
    Abstract: The present invention achieves power savings by turning off all or some of the baseband processing for codes and timeslots that have not been transmitted due to full or partial DTX. With respect to partial DTX, the transmitted codes and associated timeslots and radio frames within the shortest TTI in the CCTrCH are determined from the received TFCI. Thereafter, the receiver is turned off for the unused codes as indicated by the received TFCI. With respect to full DTX, following TFCI reception, the receiver is turned off for all timeslots within the shortest TTI.

  • Publication number: 20030086381
    Abstract: A system and method that achieve power savings by turning off all or some of the baseband processing for codes and timeslots that have not been transmitted due to full DTX. When full DTX is detected by reception of a Special Burst (SB), the receiver is turned off for all timeslots and frames for the duration of the Special Burst Scheduling Period (SBSP). The transmitter schedules transmissions following any idle period to start on the boundary of the SBSP. The receiver determines the SBSP and if the transmitter initiates transmissions according to SBSP by reception of several initial full DTX cycles.

  • Publication number: 20030072276
    Abstract: A system and method for reducing the unused capacity of a wireless communication channel utilize the data fields of an SB in order to signal physical layer control signaling for coordination between a Node B and a UE. The control signaling may include improved reception of SBs, enclose transmit power control commands or any physical layer control signaling for coordination between the UE and the Node B for synchronization timing advance or reconfiguration of the physical channel. This system and method may be applied independently to the uplink and the downlink.

  • Publication number: 20030063576
    Abstract: The present invention is a receiver for receiving a communication signal divided into a plurality of timeslots, wherein the timeslots include a plurality of channels, including a burst detector for detecting when a selected one of the plurality of channels of the communication is received. The burst detector comprises a noise estimation device for determining a scaled noise power estimate of the selected one of the timeslots, a matched filter for detecting signal power of the selected one of the timeslots and a signal power estimation device, responsive for the matched filter, for generating a signal power estimate of the, selected one of the timeslots. A comparator responsive to the scaled noise power estimate the signal power estimate is also included in the burst detector for generating a burst detection signal when the signal power estimate is greater than the scaled noise power estimate, and a data estimation device, responsive to the burst detection signal, for decoding the plurality of channels.

  • Patent number: 4520887
    Abstract: A simple holddown structure for securely mounting a storage battery or the like is in the form of an integrally molded bracket member of corrosion-resistant material having two spaced-apart parallel angled members adapted to engage opposite upper edges of the battery and interconnected by a cross-bar member, the opposite ends of which are formed with an eyelet and an upstanding tab formation both extending beyond the angled members. The eyelet accommodates a fastener securing one side of the bracket member to a mounting structure and the tab cooperates with a separate L-shaped member having a series of apertures in one arm for selectively receiving the tab therein. The other arm of the L-shaped member has a slot accommodating a fastener for adjustably securing the other side of the bracket member to the mounting structure.
