Patent (populärvet., debatt m.m.)abstract
- NOVELTY - A superposition of signals received from transmitting nodes (10), at receiving nodes (120) is converted to produce soft complex signal information for transmission over network. The signal information transmitted from a subset of transmitting nodes, is collectively detected based on the soft complex signal information. USE - For detecting signal information in digital cellular network of wideband code division multiple access (WCDMA) system. ADVANTAGE - Reduces amount of information to be transported over the network, thereby improving the performance of the network and improving the uplink signal processing efficiency at low cost. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) system for detecting signal information in wireless network; (2) network node. DESCRIPTION OF DRAWING(S) - The figure shows a schematic diagram of the centralized architecture and signal processing approach. transmitting nodes (10) receiving nodes (120-1-120-3)

Method and Apparatus in a Mimo Based Communication System
- 2003
-
Patent (populärvet., debatt m.m.)abstract
- NOVELTY - The communication parameters are adapted for set of user terminals based on principle used for optimizing communication with respect to partial channel state information (CSI) by singular value decomposition (SVD). The parameters for another set of terminals, are adapted based on another principle to optimize multiple input and multiple output (MIMO) communication. The parameters are then sent to respective set of terminals. USE - For communicating between user terminals in multiple input multiple output (MIMO) based communication network (claimed). ADVANTAGE - Optimized communication between the user terminals is obtained effectively. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) transmitter node; and (2) multiple input multiple output based communication network. DESCRIPTION OF DRAWING(S) - The figure shows the schematic diagram of the SVD-based MIMO system. (Drawing includes non-English language text). scheduling unit (9') feedback channels (17,19) preprocessor (91) transmitter (T4)

- 2003
-
Patent (populärvet., debatt m.m.)abstract
- NOVELTY - The method involves determining specific and common transmission parameters for relay station based on which the signals are forwarded from one link between transmitter (210') and relay station, to another link between relay station and receiver (220'). USE - For communication in two hop wireless communication network. ADVANTAGE - Ensures more precise and reliable characterization of individual radio paths, and optimizes different transmission parameter, so as to fully exploit the network. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) relay station adapted in two hop wireless communication network; (2) system for communication in two hop wireless communication network; (3) receiver; (4) base station; and (5) mobile station.

Method and device for joint retransmission
- 2005
-
Patent (populärvet., debatt m.m.)abstract
- NOVELTY - A data stream is partitioned at a transmitting node into at least two data sub streams which undergo beam forming before being transmitted over a first link to the respective relay nodes. At least one restorable representation of the received sub stream from each relay node is forwarded over a second link to at least one receiving node where the representation is decoded and multiplexed to form an output signal corresponding to the data stream. USE - For wireless communication system. ADVANTAGE - Provides improved relaying scheme in communication system. Enables spatial multiplexing with improved spectrum efficiency. Allocates power between transmitter and relays with decreased power consumption and reduced generated interference. Enables cooperative relaying with increased overall system capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (A) a communication system; (B) a transmitting node; (C) a relay node; and (D) a receiver node. DESCRIPTION OF DRAWING(S) - The figure is a schematic flow diagram of the cooperative relaying method.

Method and system for wireless communication networks using cooperative relaying
- 2003
-
Patent (populärvet., debatt m.m.)abstract
- NOVELTY - The method involves selecting relay channels (530:1-530:k) associated with the relay stations (415) having spatial overlap coverage at the mobile station, for establishing communication session between the base station and mobile station. USE - For communication such as multiple input-multiple output (MIMO) communication between base station (claimed) and mobile station in two-hop wireless communication network such as radio access network and cellular network. ADVANTAGE - The MIMO communication between the base station and mobile station is optimized using the relay stations without any increase in excessive control signaling over the air interface. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) system for communication in two-hop wireless network; (2) receiver; and (3) base station. DESCRIPTION OF DRAWING(S) - The figure shows a logical block diagram of the wireless communication system. relay station (415) base station transmitter (510) transmit antennas (513) mobile station receiver (520) relay channels (530:1-530:k) transmit channel (535)
