A device receives available capacity and used capacity associated with a network, receives a connection request from a user device in the network, and receives a maximum capacity threshold associated with the network. The device calculates a minimum capacity threshold and a medium capacity threshold, associated with the network, based on the maximum capacity threshold. The device also determines whether to admit or deny the connection request based on the available capacity, the used capacity, the minimum capacity threshold, the medium capacity threshold, and the maximum capacity threshold. The device further allocates, when the connection request is to be admitted and based on resource availability associated with the network, a particular bit rate, for a particular quality of service (QoS) class, to the connection request.

In a 60 Hz WGA wireless network, not all frames with the duration field are received by a STA in a WGA network because of directional antennas. Therefore, a NAV Timer cannot account for the reserved duration of the channel by only updating with the longest duration field received. A STA can receive two frames each with a source and destination addresses and update the NAV Timer by comparing the received addresses to overcome such problem. Further, a STA can receive one frame with a source and destination addresses and update the NAV Timer by comparing the received addresses with the NAVSRC and NAVDST values.

Messages transmitted between a receiver and a transmitter are used to maximize a communication data rate. In particular, a multicarrier modulation system uses messages that are sent from the receiver to the transmitter to exchange one or more sets of optimized communication parameters. The transmitter then stores these communication parameters and when transmitting to that particular receiver, the transmitter utilizes the stored parameters in an effort to maximize the data rate to that receiver. Likewise, when the receiver receives packets from that particular transmitter, the receiver can utilize the stored communication parameters for reception.

Принадлежит: Motorola Inc

A method is provided to determine optimal data rate and packet length in mobile networks. The method directly determines the optimal packet length (L) and data rate (D), which allows fast convergence in the mobile channel. The method automatically identifies and quantifies channel conditions, as well as adjusts parameters according to changes of channel conditions. A variable (Channel condition Index (CCI)) is abstracted from simulations and then used to describe and quantify the impact of three components of channel conditions: signal-to-noise ratio (SNR), multipath environment and velocity. Based on packet completion rate (PCR) status, the channel condition is identified in terms of CCI value. Once CCI is identified, the model of effective throughput G is directly optimized to locate the best packet length (L) and data rate (D).

Method and apparatus for compressing channel state information based on path location information

Номер: US20130201912A1
Принадлежит: InterDigital Patent Holdings Inc

Methods and apparatus are described for compressing channel state information (CSI) in time-domain based on path location information for CSI feedback. Downlink (DL) CSI is compressed in the time domain and fed back by not sending the multipath location information, or sending at a very low rate. In one method, a wireless transmit/receive unit (WTRU) selects the strongest multipath components based on channel characteristics. The multipath components are quantized in the time domain via direct or vector based quantization. The base station reconstructs a channel impulse response from the fed back quantized multipath components and applies same to precoding processing. In another method, the WTRU feeds back information associated with a narrowband portion(s) of a system spectrum. The selected narrowband portion(s) have sufficient density over time to allow good precoding per subband or across the system spectrum. Short term feedback may be augmented with long term channel information.

Since the computational burden of processing the narrow bandwidth downlink signals is less than that for processing the wide bandwidth downlink signals, a power reduction in the UE is realized from the reduced computational load. A normal handover between cells with wide and narrow bandwidth downlinks can be used. Alternatively, a single cell can dynamically change its downlink bandwidth resulting in a reduced computational load and reduced power consumption in the UE.

The transport network employs a window-based state providing a window-based congestion control mode for a data flow. This mode involves notifying an application level transport protocol implemented in a sending source of the communication network of any detected congestion event. If a congestion event in the transport network is detected a switch to a rate-based state is performed. The rate-based state provides a rate-based congestion control mode involving transmitting a rate-reducing message from the radio access node to the control node to trigger a reduction in the bitrate of the data flow in response to the detected congestion event.

A method , comprising: detecting in a wireless communication network an excess capacity condition , in response to offloading; and increasing , from a currently subscribed-to value , to a higher value of an aggregated maximum bit rate for a mobile node operating in the wireless communication network.68. The method of claim 67 , where detecting comprises informing a user of the mobile node of the detected excess capacity condition claim 67 , and where increasing is performed in response to a request received from the user of the mobile node.69. The method of claim 67 , wherein offloading is triggered by at least one of carrier aggregation claim 67 , secondary cell activation claim 67 , heterogeneous network connection claim 67 , local breakout claim 67 , and secondary PDN connection activation.70. The method of claim 67 , where increasing comprises using another wireless communication network for offloading in place of or in combination with a currently used wireless communication network.71. The method of claim 67 , where increasing comprises using carrier aggregation to increase data transfer capacity of the wireless communication network.72. The method of claim 67 , where detecting is accomplished by the mobile node in response to the wireless communication network configuring at least one secondary cell.73. The method of claim 67 , where a presence of the excess capacity condition is determined by the wireless communication network based on at least one of an actual ...

Techniques enabling dynamic bandwidth reservation in a wireless personal area network

Номер: US20140003402A1
Принадлежит: Individual

An embodiment of the present invention provides a method, comprising dynamically reserving free channel time blocks for directional transmissions in a wireless personal area network (WPAN) by a transceiver communicating with a Coordinator and the Coordinator allocating a part or a whole of unreserved channel time blocks for a directional link during a handshake with the transceiver.
