摘要： A MIMO antenna used in both transmit and receive operations, with the ability to serve an n-by-n MIMO transceiver architecture (where n can take integer values between 0 to 4). The structure is designed to increase the effective area of the array by coupling the bars of the antenna to the disc and results in good isolation and low envelope correlation.

摘要： An IP packet transmission system is disclosed and more specifically it is a system using a hybrid ARQ method including a sliding purge window and having the transmitter opportunistically piggy-back a snapshot of the transmitter's transmit/send window in data frames. When the receiver receives this snapshot the receiver can compare it with its receive window and if a mismatch is detected, whereby the transmitter has moved on to the next packet, the receiver can now also sync up quicker and not wait for the regular timeout to progress ahead.

摘要： A mechanism for decreasing the latency in an IP address assignment process for mobile systems using IP as network layer protocol is described. The proposed system is aimed at supporting seamless hand-offs for real-time applications like VOIP. A set of optimized messages is defined to eliminate the need for exchanging long DHCP messages to acquire an IP address. The mechanism involves splitting the IP address assignment functionality into two parts, with the base station being responsible for assigning IP addresses to individual end user devices, and the Mobile Switching Center assigning a block of IP addresses to each base station.

摘要： A cognitive radio signal processing method suitable for single receiver devices where interference is mitigated using projection of received multi-dimensional signal space to maximize SNR by orthogonalizing interference is described. The method is based on a well-known LMS solution that is computed from received multi antenna and multicarrier signals in a novel way. This method solves the requirement of multiple RF chains in low cost handsets by introducing a protocol synchronous antenna switcher that allows, for example, a LTE handset with a single antenna to benefit from algorithms that typically require multiple receivers for the same frequency, i.e. MIMO.

More specifically a technique to address the problem of accurate location management during rapid handoff across multiple base stations is described in this invention disclosure.

摘要： What is described is an approach to assigning timeslots of appropriate duration when using a TDMA based MAC protocol for forwarding VOIP traffic. It is known that a typical user speaks only 35% of the time in a voice session. Existing VOIP systems exploit this fact and reduce the amount of data generated by employing Voice Activity Detection (VAD) algorithms. The packets generated when a user is silent are shorter than the packets generated when a user is speaking. Hence there is a need to assign timeslots of different duration based on user speech activity. When the user is speaking we assign an Active Speech Timeslot (AST). When the user is listening a Silent Speech Timeslot (SST) that is long enough to transmit packets generated by a Comfort Noise Generator is assigned.
