27 Jan 2012TL;DR: In this article, the channel and interference estimations in a coordinated multi-point (CoMP) environment were investigated, where an eNB may be equipped to signal an identifier indicating a plurality of resource patterns, each associated with a resource pattern group, and each including a first resource element pattern for channel estimation and a second resource element patterns for interference estimation.
Abstract: Aspects disclosed herein relate to channel and interference estimations in a coordinated multi-point (CoMP) environment. In the disclosed aspects, an eNB may be equipped to signal an identifier indicating a plurality of resource patterns, each associated with a resource pattern group, and each including a first resource element pattern for channel estimation and a second resource element pattern for interference estimation. The UE may be equipped to receive the signaling and perform channel estimation based at least in part on the first resource element pattern, and interference estimation based at least in part on the second resource pattern generate at least one channel state report based on the channel and interference estimations, and transmit at least one channel state report to an eNB. The eNB may determine one or more resources for use by the UE based on the at least one received channel state report.

TL;DR: The Viterbi decoder presented here is the lowest power and smallest area core in its class, to the best of the authors' knowledge.
Abstract: An efficient state-sequential very large scale integration (VLSI) architecture and low-power design methodologies ranging from the system-level to the layout-level are presented for a large-constraint-length Viterbi decoder for code division multiple access (CDMA) digital cellular/personal communication services (PCS) applications. The low-power design approaches are also applicable to many other systems and algorithms. VLSI implementation issues and prototype fabrication results for a state-sequential Viterbi decoder for convolutional codes of rate 1/2 and constraint-length 9 are also described. The chip's core, consisting of approximately 65 k transistors, occupies 1.9 mm by 3.4 mm in a 0.8-/spl mu/m triple-layer-metal n-well CMOS technology. The chip's measured total power dissipation is 0.24 mW at a 14.4 kb/s data-rate with 0.9216 MHz clocking at a supply voltage of 1.65 V. The Viterbi decoder presented here is the lowest power and smallest area core in its class, to the best of our knowledge.

13 Sep 2004TL;DR: In this paper, a method and a system for providing signaling in cellular telephone system providing broadcast services to fully integrate broadcast services with the services provided by the cellular telephone systems is presented.
Abstract: A method and a system for providing signaling in cellular telephone system providing broadcast services to fully integrate broadcast services with the services provided by the cellular telephone systems. The signaling method coordinate interaction between an access network and the subscriber station to allowing the subscriber station to decode the broadcast service, to receive paging messages while receiving the broadcast service, to properly transition between operation states, and other functions known to one of ordinary skill in the art.

17 Feb 2004TL;DR: In this article, a method and apparatus for enhanced user control of location information for mobile devices is presented, which provides user control within the mobile station of privacy policies that supervise responses to requests for location information.
Abstract: A method and apparatus for enhanced user control of location information for mobile devices. The method and apparatus provide user control within the mobile station of privacy policies that supervise responses to requests for location information. In an exemplary embodiment the mobile station includes a Privacy Engine, a Position Determination Module, and a User Interface. The Privacy Engine is a software module that controls the responses of the mobile station to location requests. The Privacy Engine preferably includes a Privacy Policy that may be modified by the mobile station user by means of wireless downloads, the User Interface, or by locally connected devices such as a personal computer, personal digital assistant, or laptop. Advantageously, the Privacy Engine or the Privacy Policy may be downloaded to the mobile station by means of a wireless data network or other data connection such as Bluetooth, infrared connection, Universal Serial Bus, etc.

25 Apr 2013TL;DR: In this article, the authors proposed a scheme for swapping master/slave roles among wireless nodes (e.g., wireless earpieces) coupled to a wireless source device to optimize battery life in both wireless nodes.
Abstract: Various embodiments may provide systems and methods among wireless nodes in a wireless communication network that enable balancing the batteries in the wireless nodes to be depleted at approximately the same rate. Various embodiments intelligently and dynamically swap master/slave roles among wireless nodes (e.g., wireless earpieces) coupled to a wireless source device to optimize battery life in both wireless nodes. The various embodiments may provide methods and systems for swapping master-slave roles so that there is reduced impact on the user experience.
