摘要:
Neighbor cell hearability can be improved by including an additional reference signal that can be detected at a low sensitivity and a low signal-to-noise ratio, by introducing non-unity frequency reuse for the signals used for a time difference of arrival (TDOA) measurement, e.g., orthogonality of signals transmitted from the serving cell sites and the various neighbor cell sites. The new reference signal, called the TDOA-RS, is proposed to improve the hearability of neighbor cells in a cellular network that deploys 3GPP EU-TRAN (LTE) system, and the TDOA-RS can be transmitted in any resource blocks (RB) for POSCH and/or MBSFN subframe, regardless of whether the latter is on a carrier supporting both PMCH and POSCH or not. Besides the additional TDOA-RS reference signal, an additional synchronization signal (TDOA-sync) may also be included to improve the hearability of neighbor cells.

摘要:
The present invention provides a solution to improve coverage and cell edge performance in a mobile user communication system is the use of fixed relays, which are pieces of infrastructure without a wired backhaul connection. The relays transmit or “relay” downlink messages between the base station (BS) and mobile stations (MSs) through a multi-hop communication. The present invention is a method and system for supporting a multiple user mobile broadband communication network that includes relay techniques suitable for user equipment in the downlink communication to the user equipment.

The present invention is a method and system for supporting a beamforming antenna system in a multiple user mobile broadband communication network including a process for setting and adjusting the magnitude and phase of the signal to user equipment from each antenna. Namely, the present invention supports the communication of power signal values or levels to user equipment in a manner that keeps pace with the rapid variations of the power levels that occur in the dynamic scheduling of transmissions on the cell site. The present invention satisfies this need for an improved signal strength signaling to user equipment for the situation where multiple users are located on the cell site.

A method and system for wireless data communication using a first wireless communication technology and a second wireless communication technology. The second wireless communication technology being different from the first wireless communication technology. A transmitter is arranged to transmit data using frame structures based on the first wireless communication technology and the second wireless communication technology in which the frame structure based on the second wireless communication technology has a timing structure, MAC and pilot that are also used with the frame structure of the first wireless communication technology. The transmitter is arranged to selectively change transmission on a frame by frame basis between the first wireless communication technology and the second wireless communication technology.

摘要:
In a method of providing downlink retransmissions to a mobile station in a wireless communication network, the wireless communication network comprising a base station communicatively linked to a transparent relay station, the base station receives a request for a retransmission from the mobile station; schedules resources for the retransmission; signals scheduling information for the retransmission to the transparent relay station via a control link; and the transparent relay station receives the scheduling information for the retransmission on the control link; and sends the retransmission to the mobile station in a retransmit subframe on a retransmit frequency band.

A method and apparatus are provided for a wireless communication system including a base station and at least one user equipment. A Channel Quality Indicator (CQI) table can be generated so that only an index corresponding to the measured CQI needs to be fed back to the base station. The CQI tables proposed herein may be suitable to different channel statistics, different Multiple Input Multiple Output (MIMO) mode and may be optimized based on either performance or implementation complexity. Multiple CQI tables may be formed into one compound CQI table. The CQI tables may be stored at both a base station and user equipment. The base station can select a CQI table from the set of tables. The base station signals the selection of the CQI table to the user equipment and the user equipment feeds back indices from the selected CQI table to the base station.
