Methods and systems for enabling feedback in wireless communication networks

Номер: US20120106483A1

Автор: Hang Zhang, Jianglei Ma, Mo-Han Fong, Peiying Zhu, Wen Tong

Принадлежит: ROCKSTAR BIDCO LP

Aspects of the present invention provide additional MAC functionality to support the PHY features of a wireless communication system framework. The additional MAC functionality aids in enabling feedback from wireless terminals to base stations. In some aspects of the invention the feedback is provided on an allocated feedback channel. In other aspects of the invention the feedback is provided by MAC protocol data units (PDU) in a header, mini-header, or subheader. The feedback may be transmitted from the wireless terminal to the base station autonomously by the wireless terminal or in response to an indication from the base station that feedback is requested. Aspects of the invention also provide for allocating feedback resources to form a dedicated feedback channel. One or more of these enhancements is included in a given implementation. Base stations and wireless terminals are also described upon which methods described herein can be implemented.

A method and system reduce interference between overlapping first and second wireless LAN cells contending for the same medium. Each cell includes a respective plurality of member stations. An inter-cell contention-free period value is assigned to a first access point station in the first cell, associated with an accessing order in the medium for member stations in the first and second cells. The access point in the first cell transmits an initial shield packet to deter other stations from contending for the medium. The access point then transmits a beacon packet containing the inter-cell contention-free period value to member stations in the second cell. A second access point in the second cell can then delay transmissions by member stations in the second cell until after the inter-cell contention-free period expires.

A communication system comprising one or more wireless stations programmed to await for an authorizing signal to initiate wireless communications with a network controller or access point. The network controller maintains identification information in different queues, and polls stations from those queues. The wireless station identification information may be moved between the different queues in response to wireless station activity. Between polling, each mobile station aggregates data for the next opportunity to transmit. Multi-polling may be employed such that more than a single station is polled at a time. Polling is accomplished by polling one of the more stations from each queue having the effect that stations in one queue are polled more often than those in another queue. If a lesser active station becomes active, it may be moved into the shorter queue and consequently will be polled more often. 1. A system comprising:a network controller operable to:maintain wireless station identification information in at least a first queue and a second queue;poll a plurality of wireless stations, each of said stations from a different queue, by encoding the polling signal to address the plurality of stations, andallocate transmission time for the wireless stations in response to said polling.2.

Techniques are described herein for fast and efficient discovery of small cells by user equipment (“UE”) in a wireless telecommunications network. The small cells may operate at a high frequency band (“HFB”), which may correspond to higher frequencies than other cells (e.g., base stations, such as evolved Node Bs (“eNBs”)) of the network. The UE may receive assistance information, which may include polling channel configurations, beamforming weights, carrier frequencies, cell identifiers of small cells, and/or other information. The UE may use the assistance information when outputting (either omnidirectionally, pseudo-omnidirectionally, or directionally) a polling sequence, in order to detect the small cells.

A system and method for managing power in a subnet having a hub in communication with one or more nodes is disclosed. The hub and nodes communicate using one or more non-contention access methods, such as scheduled, polled or posted access. The node may enter a sleep or hibernation state while no scheduled, polled or posted allocation interval is pending. The hibernation state allows the node to hibernate through one or more entire beacon periods. In the sleep state, the node may be asleep between any scheduled, polled and posted allocation intervals for the node or during another node's scheduled allocation interval in a current beacon period. By selecting which access scheme is in use, the node and hub can increase the node's chances to be in hibernation or sleep state and minimize power consumption.

According to the invention, there is provided a method for allowing abstract wireless links, i.e., arbitrary cooperation among a set of proximate wireless nodes, to be established between devices in a fast and efficient manner. Beneficially the approach allows multi-standard cognitive radios to operate in ad-hoc environments and non-ad-hoc environments. Accordingly a wireless module monitors a plurality of sensing tones and polling tones, each pair of sensing and polling tones associated with a transmission channel. A wireless module determines a vacant transmission channel by the absence or both a sensing tone and its associated polling tone. An abstract wireless link could be established by the wireless module transmitting the polling tone associated with the vacant transmission channel and detecting from second other wireless modules the sensing tone associated with the vacant transmission channel.
