Abstract: A method is provided to reduce inter-cell interference in mobile wireless systems, and particularly in TDD wireless systems. In an embodiment, a base station receives a pilot signal from at least one of the mobile terminals that it serves at a plurality of base station antennas, which include both main antennas and auxiliary antennas. In response, each of the base station antennas provides an output that is processed to obtain a set of precoding weights for a transmission from the main antennas. The processing includes nulling at least one interfering signal using the outputs from at least the auxiliary antennas.

Abstract: The present invention provides, in one embodiment, a method for detecting another device performed by a first device having a converged personal network service (CPNS) enabled entity. The method for detecting another device comprises the steps of: performing a procedure for a physical connection with a second device, if the CPNS enabled entity within the first device is set to a personal network entity (PNE) mode; and receiving a search request message from the second device, in order to prevent the duplication of information between the CPNS enabled entity and the second device. Preferably, said search request message can be used to obtain one or more pieces of information, among the mode information of one or more devices detected while the procedure for the physical connection is performed and the information on a network to which one or more said detected devices belong.

Abstract: A queuing method and system for wireless/LAN routers processes and routes an incoming data packet from a wireless mobile network to a destination server. The system uses a wireless transport module to initiate storage of the data packet in a permanent storage device while simultaneously forwarding the data packet to the destination server. A database thread is used to manage the operations being performed on the data packet and for initiating the storage of the data packet in a permanent storage device based on a permanent storage queue. A main thread is used to simultaneously forward the data packet to the destination server. The wireless transport module is adapted to determine whether the data packet has been acknowledged by the destination server and aborting the storage of the data packet in the permanent storage device once acknowledgment from by destination server has been received.

Abstract: Methods and apparatus for improving the efficient use of a wireless channel. Flows of compatible packets to be transmitted are processed in separate queues based on characteristics of the packets, destination and quality of service (QoS) requirements. Aggregation parameters selected for each flow define when packets aggregated on a flow are to be sent. The aggregation parameters may reflect packet type, such as QoS requirements, an application type and/or wireless channel conditions. In some embodiments, the aggregation parameters indicate a threshold frame size or include a threshold time to buffer a packet while waiting for other packets on that flow to fill a frame. When an aggregation parameter for a queue is met, the aggregated packets are transmitted as a frame. The queue is cleared and subsequent packets may begin aggregating. Some types of packets, such as acknowledgment packets, may be sent without aggregation.

Abstract: This system provides wired and/or wireless access throughout a multimedia network built on a distributed architecture which can be transparent to the user. This multimedia network includes content which is imported or generated within the network. The system allows for the content provider to determine the license status of content and update the license status of content which was previously provided by that provider. The external content can be accessed in real time or downloaded and stored within the system for later access at the convenience of the user. The usage of some content is controlled by the use of encryption and other protection methods. The system allows for storage of live video by storing the digitized video and allowing the user to control how, when and where the content is viewed. The system makes available multiple multimedia services to all users in the network or connected via the internet.

Abstract: A frame time having a certain period of time is divided into: a time period (for inter-base-station time division multiplex communication) in which one of the base stations has a transmission right in the simultaneous transmission and carries out inter-base-station time division multiplex communication so as to avoid interference between the base stations; and a time period (for inter-base-station simultaneous communication) for communication which is simultaneously carried out between the plurality of base stations. Furthermore, the time periods are switched for the communication.

Abstract: Methods and apparatus are provided for transmitting and receiving reference signals through distributed antennas deployed within a service area of a base station in a mobile communication system. First control information, including at least two scrambling factor combinations, is received at a terminal from the base station. Second control information, indicating one of the at least two scrambling factor combinations, is received at the terminal from the base station. The one of the at least two scrambling factor combinations is selected based on the second control information. An initial value of a demodulation reference signal sequence is calculated using the selected scrambling factor combination. The demodulation reference signal sequence is received using the initial value.

Abstract: Systems and methodologies are described that facilitate providing flow control feedback for controlling downlink data transmission rates. Various schemes can be utilized to send the flow control feedback from an access terminal to a base station. For example, a control PDU (e.g., MAC control PDU, PDCP control PDU) can be generated based upon a level of resource utilization of the access terminal, and sent to the base station for controlling the downlink data transmission rate. Following this example, a type of control PDU, a value included within the control PDU, etc. can be selected as a function of the level of resource utilization. By way of another illustration, a CQI report that includes a value selected as a function of the level of resource utilization associated with the access terminal can be generated and transmitted to the base station for controlling the downlink data transmission rate.

Abstract: A mask packet is provided with bits in a ONE state for all predictable bit positions and with a ZERO state for all unpredictable ones. All predictable bit positions of the new data packet are brought into a ZERO state if an actual bit state matches the predicted bit state and into a ONE state if the actual bit state does not. A processed packet is generated by applying an AND operation between the new data packet and the mask packet to change all unpredictable bits to a ZERO state. A series of counters is provided by calculating the number of bits in the processed packet between the first bit and the first bit with a state ONE; and between the following bits with a state ONE and between the last bit with a state ONE and the last bit in the processed packet. The counters are stored or transmitted.

Abstract: A system and method of automatically configuring a Service Instance Identifier (I-SID) in a Generalized Multiprotocol Label Switching (GMPLS) controlled network. The method begins by identifying a specific I-SID for a specific service in the GMPLS controlled network. Next, the identified I-SID is automatically configured within a Backbone Edge Bridge (BEB) with a Resource Reservation Protocol-Traffic Engineering (RSVP-TE) extension. The automatic configuration may be implemented by several different embodiments. In one embodiment, the I-SID may be carried in a SESSION_ATTRIBUTE object. In another embodiment, the I-SID may be mapped to a Short Call ID field in a Session object. Alternatively, the I-SID may be carried in an Endpoint ID Type-Length-Value (TLV). The I-SID may also be carried in a new TLV in a LSP_ATTRIBUTES or CALL— ATTRIBUTES object.
