A 5-bit “Coding” field is configured in the header of the involved RLC/MAC messages to select the transmitting/receiving window size. An additional signaling bit, also called scaling bit, is asserted/negated according to two opportunities offered by the new MAC protocol to properly select the window size. Thanks to the introduction of the scaling bit a subdivision of the time windows for type of services is made possible. Non real-time services, e.g. file transfer, all of standard window sizes for MSs with multistat capability, as reported in 3GPP TS 44.060, V7.3.0 (2006 February), Release 7, subclause 9.1.9, for EGPRS TBFs. Delay-sensitive services, e.g. media or multimedia real-time transmissions, avail of new window sizes with scaled down values remapped to start from 1 to (maximum) 64 RLC/MAC blocks.

Both peer entities comprised in a TBF are receiving the RLC/MAC messages with the proper setting of the scaling bit and the 5-bit coding IF; these entities decode the scaling bit and behave accordingly. The behavior includes either assuming the standard window size or scaled window size addressed by the same predetermined 5-bit “coding” information element. | 05-28-2009 |

A shadow fading determination module is also in signal communication with the wireless access points. The shadow fading determination module determines a shadow fading factor based on the distance between a pair of the wireless access points and based on RSS information received from one of the wireless access points in the pair of wireless access points. | 05-05-2016 |
20160127920 | Methods and Apparatus for Antenna Elevation Design - Systems and techniques for elevation beam design. Characteristics, such as number, distribution, and geographical location of elements subject to interference by elevation beams of a base station are analyzed, and a configuration for an antenna array is determined so as to create a set of elevation beams directed so as to avoid interference with the elements subject to interference by the base station. Configuration may, for example, include configuration of the antenna array so as to create a set of elevation beams exhibiting nulls and sidelobes in appropriate locations and at appropriate angles so as to avoid interference. | 05-05-2016 |

20160165459 | COMMUNICATION SYSTEM - A communication system includes a user equipment (UE), and a plurality of cells that perform communication with the UE. The plurality of cells include a macro cell having a relatively-wide-range coverage, and a plurality of small cells having a relatively-narrow-range coverage. The plurality of small cells are connected to a concentrator. The concentrator selects the small cell to which the UE is to be connected, from among a plurality of small cells, based on the flow of at least either one of the received data that each small cell receives from the UE and the transmission data that each small cell transmits to an MME and an S-GW. | 06-09-2016 |

20160192202 | Methods And Apparatus For Small Cell Deployment In Wireless Network - A method of small cell deployment is performed in response to an initialization request or a performance alarm. The method includes selecting an initial number (N) of small cell candidate locations of one or more feasible small cell locations for small cells on a three dimensional grid of nodes representation of an area of interest and determining, feasible M-sized small cell tuples having small cells that do not conflict with each other, wherein M has an initial value less than or equal to N. The method also computes at least one performance Key Performance Indicator (KPI) for a subset of the feasible M-sized small cell tuples, and searches for a first tuple of the subset of the feasible M-sized small cell tuples, the at least one performance KPI of the first tuple satisfying one or more constraints on the small cell deployment. | 06-30-2016 |
20160192204 | METHOD AND APPARATUS FOR ASSIGNING CELL IDENTIFIER VALUES AND METHOD AND APPARATUS FOR MANAGING ASSIGNMENT OF CELL IDENTIFIER VALUES IN A COMMUNICATION NETWORK - The present invention relates to a method and apparatus for automatically assigning cell identifier values in a communication network and to a method and apparatus for managing the assignment of cell identifier values in a communication network. In particular, the present invention relates to the management and assignment of cell identifier values that are required to be unique between adjacent cells, in a border region within a communication network in which cells from two or more cell sets are present. The present invention provides a novel method and apparatus for assigning cell identifier values in a communication network and for managing the assignment of cell identifier values in a communication network. Embodiments of the invention enable the automatic assignment of cell identifiers in a communication network, such as the assignment of physical cell identities (PCI) and scrambling codes (SC) in a Long Term Evolution (LTE) network. The need for manual administration in border areas between cell sets managed by different Operation Support Systems (OSSs) can therefore be reduced or eliminated. | 06-30-2016 |
