摘要： In a method of communication, a first type of data packet is received. The first type of data packet is at least a portion of a second type of data packet. Based on the received first type of data packet, a determination is made as to whether to expect receipt of a subsequent first type of data packet in a given time interval. A status signal is sent if the subsequent first type of data packet is not received in the given time interval as determined in the determining step. In another method of communication, a data packet is received at a physical layer over a circuit switched physical channel. A status of the data packet is determined at the physical layer. A status report is sent to a higher protocol layer based on the determination.

摘要： A method and apparatus are disclosed for reducing leakage power in a cache memory. A cache decay technique is employed for both data and instruction caches that removes power from cache lines that have not been accessed for a predefined time interval, referred to as the decay interval. The cache-line granularity of the present invention permits a significant reduction in leakage power while at the same time preserving much of the performance of the cache. The decay interval is maintained using a timer that is reset each time the corresponding cache line is accessed. The decay interval may be fixed or variable. Once the decay interval timer exceeds a specified decay interval, power to the cache line is removed. Once power to the cache line is removed, the contents of the data and tag fields are allowed to decay and the valid bit associated with the cache line is reset. When a cache line is later accessed after being powered down by the present invention, a cache miss is incurred while the cache line is again powered up and the data is obtained from the next level of the memory hierarchy.

摘要翻译： 公开了一种用于减少高速缓冲存储器中的泄漏功率的方法和装置。 缓存衰减技术被用于数据和指令高速缓存，这些高速缓存从预定义的时间间隔（称为衰减间隔）中去除未被访问的高速缓存行的功率。 本发明的高速缓存线粒度允许显着降低泄漏功率，同时保持高速缓存的大部分性能。 使用每次访问相应的高速缓存行时重置的定时器来维持衰减间隔。 衰减间隔可以是固定的或可变的。 一旦衰减间隔定时器超过指定的衰减间隔，就删除高速缓存行的电源。 一旦去除了高速缓存线的电源，就允许数据和标签字段的内容衰减，并且与高速缓存行相关联的有效位被重置。 当通过本发明关闭高速缓存行之后，高速缓存未命中，同时高速缓存行再次通电并且从存储器层级的下一级获得数据。

摘要： Dynamic reorganization of cell structures in wireless networks. The present invention relates to wireless communications and, more particularly, to energy usage of wireless equipments in wireless communications. Currently there are mechanisms in use that can selectively turn of carriers in a BTS depending on the traffic load. But due to the fixed costs of operating the base station even when there are no active users, turning off entire BTS will give more energy savings than simply reducing capacity by turning off carriers at low load. Embodiments herein detect a change in demand on the network and re-organize the cellular network by selectively turning off BTSs and appropriately increasing the coverage area of other BTSs, and arrive at a configuration that optimizes the energy consumption of the cellular network as a whole.

摘要： A method and apparatus for scheduling the transmission of data packets over a multihop wireless backhaul network in which delay guarantees through the network may be advantageously ensured. Illustratively, a novel packet scheduling scheme is provided which is advantageously based on an existing scheduling policy for wireline networks and for which a delay guarantee (based on the delay characteristics of the existing scheduling policy) can be advantageously ensured. In one embodiment, an even-odd link activation framework is defined for a given multihop wireless backhaul network, and an associated scheduling policy based on an arbitrary existing scheduling policy for wireline networks is derived and adopted. In such a case, the derived scheduling policy, when applied to the given multihop wireless backhaul network, advantageously ensures a worst-case delay guarantee of approximately twice that of the existing scheduling policy for wireline networks.

摘要： A system and method for caching and pre-fetching content is disclosed. This invention relates to mobile devices and, more particularly but not exclusively, to delivering content to a mobile device. Existing systems employ different mechanisms for delivering content such as multimedia and the like to users of mobile device. Mechanisms such as broadcast services, delivery from the interne, Wi-Fi hotspots, Bluetooth kiosks etc face problems of offering innovative services to users due to insufficient network capacity, high end costs to consumers. The disclosed system delivers contents such as multimedia, data and the like by pre-fetching and caching techniques. The contents preferred by a user is identified and pre-fetched to access points located in vicinity of the user. The user can access the contents from the access points via a short range communication means such as Bluetooth, Infrared and so on.
