Abstract: PROBLEM TO BE SOLVED: To provide transmission techniques using configurable channels for the downlink and/or uplink.SOLUTION: The downlink channel and/or uplink channel may be independently selected for a terminal. The terminal may establish a connection with a base station on default downlink and uplink channels. Another downlink channel and/or another uplink channel may be selected based on various factors such as channel quality, loading, and interference. The terminal would then switch to the new downlink and/or uplink channel for communication.

Abstract: The invention described herein enables a form of downlink macro-diversity in packet-switched cellular networks. It allows packets (650, 650', 652, 652', 654, 654', 656, 656', 658, 658', 660, 660', 662) to be selectively delivered from a network/internetwork to an end node (200), e.g., wireless communication device or terminal, over a set of available link-layer connections (402, 502) to/from the end node (200), through one or more access nodes (300, 300'), e.g., base stations. Downlink macro-diversity is particularly important when the link layer connections (402, 502) between the end node (200) and the corresponding access node (300, 300'), e.g., the access links, are subject to independent or partially correlated time variations in signal strength and interference. In accordance with the invention, the end node (200) dynamically selects a downlink (402, 502) to be used out of a set of available access links on a per packet basis subject to prevailing channel conditions, availability of airlink resources and other constraints. The invention improves the robustness and efficiency of communication, overall utilization of air-link resources, and quality of service experienced by the end node (200).

Abstract: Techniques for mitigating temporary loss of synchronization in a wireless communication system are described. In an aspect, a cell may periodically broadcast a mode indicator to indicate synchronous operation or asynchronous operation by the cell. The cell may also broadcast its cell identity (ID), which may omit the mode indicator and would then remain unchanged when the cell switches between asynchronous and synchronous operation. In another aspect, the cell may send system time information indicative of its updated system time when switching from asynchronous operation to synchronous operation. The updated system time may be used for communication with terminals after the switch to synchronous operation. In yet another aspect, the cell may decrease its transmit power prior to switching synchronization mode, switch synchronization mode when its transmit power reaches a predetermined power level, and thereafter increase its transmit power.

Abstract: Se describen técnicas para mitigar la pérdida temporal de sincronización en un sistema de comunicación inalámbrica. En un aspecto, una célula puede difundir periódicamente un indicador de modo para indicar la operación sincrónica u operación asincrónica por la célula. La célula también puede difundir su identidad de célula (ID), que puede omitir el indicador de modo y luego permanecería sin cambio cuando la célula cambia entre la operación asincrónica y sincrónica. En otro aspecto, la célula puede enviar información del tiempo del sistema indicativa de su tiempo actualizado del sistema al cambiar de la operación asincrónica a la operación sincrónica. El tiempo actualizado del sistema se puede usar para la comunicación con las terminales después del cambio a la operación sincrónica. En todavía otro aspecto, la célula puede disminuir su energía de transmisión antes de cambiar del modo de sincronización, cambiar el modo de sincronización cuando su energía de transmisión alcanza un nivel de energía predeterminado y después incrementar su energía de transmisión.

Abstract translation: 描述了用于减轻无线通信系统中的同步暂时丢失的技术。 在一方面，小区可以周期性地广播模式指示符以指示小区的同步操作或异步操作。 小区还可以广播其小区身份（ID），其可以省略模式指示符，并且在小区在异步和同步操作之间切换时将保持不变。 另一方面，当从异步操作切换到同步操作时，小区可以发送指示其更新的系统时间的系统时间信息。 在切换到同步操作之后，更新的系统时间可以用于与终端的通信。 在另一方面，小区可以在切换同步模式之前降低其发射功率，当其发射功率达到预定功率电平时，切换同步模式，然后增加其发射功率。
