| 20080205317 | Link Establishment in a Wireless Communication Environment - The invention relates to link establishment in a wireless communication terminal. In order to obtain flexible and low power connections between a wireless terminal belonging to a short-range wireless network and an external wireless communication device not belonging to that network, a protection frame is sent either from the wireless communication terminal or from the external wireless communication device. The protection frame includes duration information used for virtual carrier-sensing in the short-range wireless network. In response to the protection frame, data is transferred between the wireless communication terminal and the external wireless communication device during a time period indicated by the duration information. | 08-28-2008 |
| 20080242347 | Fast multiradio context switching - An apparatus, computer program product and method concern first and at least second radios adapted to operate according to respective first and second wireless radio systems, and which share hardware. While the first radio is inactive, first hardware configuration data HCD for the first radio is written to a first configuration register set. While the second radio is inactive, second HCD for the second radio is written to a second configuration register set. The first radio is switched to active by selecting the first configuration register and configuring at least the shared hardware according to the first HCD of the first configuration register set. The second radio is switched to active and the first radio is switched to inactive by selecting the second configuration register set and configuring at least the shared hardware according to the second HCD of the second configuration register set. For a tangible result, the respective radios transmit via according to the respective wireless radio systems. | 10-02-2008 |

Means for setting a trigger condition for executing a calibration in dependence on said received information is provided. Means are provided for executing said calibration in dependence on said trigger condition. | 11-27-2008 |
| 20090245221 | MULTIRADIO OPERATION USING INTERFERENCE REPORTING - A system for managing a plurality of wireless communication mediums that may operate in a substantially simultaneous manner. The plurality of wireless communication mediums may be supported by one or more radio modules in the same device. Parameters related to applications, device and/or wireless communication mediums may be used to create operational schedule(s) for the plurality of wireless communication mediums that dictate when each medium is allowed to be active. At least one of the plurality of wireless communication mediums may support co-located reporting, and this functionality may used in concert with the operational scheduling in order to reduce potential conflicts while also reducing resource consumption in other devices. | 10-01-2009 |
| 20100085951 | MANAGING UNSCHEDULED WIRELESS COMMUNICATION IN A MULTIRADIO DEVICE - A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. A control strategy may be employed to manage both more predictable and more spontaneous wireless communication mediums, wherein a local controller may be employed in a radio module utilizing an unscheduled wireless medium, like WLAN, for determining whether adequate time has been allocated to complete a transaction. If the transaction cannot be completed in the allowed time, it may be delayed until adequate time exists, and the delay may be reported so that the time may be reallocated to other radio modules. The radio module may then enter a power-saving mode until the transaction can be completed. | 04-08-2010 |
| 20110047539 | SOFTWARE DEFINED RADIO MANAGEMENT - A system for facilitating the management of reconfigurable communication resources. These reconfigurable communication resources may include, for example, software defined radio (SDR) modules. SDR modules may comprise fixed hardware-level support for a multitude of wireless radios whose operation/protocols are defined at the software level. A variety of software-based radio definitions (e.g., radio software) may be stored on the apparatus, the radio software defining operation/protocol for one or more radios. Radios defined in the stored radio software may be individually loaded into the SDR module in order to emulate the operation (e.g., wireless communication) of corresponding hardware-based radio modules. Loading radios into, or the unloading of radios from, the SDR module may be managed based on decision criteria. | 02-24-2011 |

| 20090291701 | Co-existence between radio access units - In a non-limiting and exemplary embodiment, a method is provided for controlling co-existence of multiple radio access units. The method comprises: receiving a scheduling request comprising value information on at least some of radio independent scheduling parameters of a control interface common to a plurality of radio access units, scheduling radio access on the basis of the value information on at least some of the radio independent scheduling parameters, and sending a response to the scheduling request in a given form in accordance with the control interface common to the radio access units. | 11-26-2009 |
| 20100115528 | Software Defined Radio - A method for providing a division of SDR RA into operational states is described. The method includes, in a device which including a plurality of shared device resources and a plurality of RAs, receiving, from a first RA, a request to change a state of the first RA to a requested active state. The requested active state is one of a plurality of potential active states for the first RA and each potential active state has an associated set of device resource requirements. The method also includes determining whether sufficient device resources exist for the requested active state based at least in part on currently allocated device resources. In response to a determination that sufficient device resources exist, the change to the requested active state for the first RA is approved. Apparatus and computer readable media are also described. | 05-06-2010 |
| 20100291942 | MULTIPLE RADIO INSTANCES USING SOFTWARE DEFINED RADIO - In a first aspect an exemplary embodiment of the invention provides a method that includes instantiating a plurality of radio protocols, operating the plurality of radio protocols with an underlying physical layer, where each instantiation of a same radio protocol is embodied in a same code module and where each instantiation has associated data stored in a memory. The operating of the plurality of radio protocols comprises executing each instantiation of the radio protocols so that a portion of resources are shared between different instantiations of the radio protocols and different instantiations of radio protocols do not interfere with each other. | 11-18-2010 |
| 20110059702 | METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR PROVIDING A FIREWALL FOR A SOFTWARE DEFINED MULTIRADIO - An apparatus for providing management of radio operation in a multiradio environment may include a processor. The processor may be configured to receive a communication in accordance with a protocol associated with a particular radio access technology in which the communication is associated with accessing a hardware resource for radio communication, determine whether the received communication complies with instructions defining parameters associated with providing shared access to hardware resources among a plurality of protocols associated with respective different radio access technologies, and respond to the received communication based on a result of the determining. | 03-10-2011 |
| 20110075596 | Resource Overbooking - In a multi-radio device it is determined that a first radio application requests change to a first operational state during a time at which a second radio application is in or requests a second operational state. A local memory is accessed to determine a first and a second budget of resources for the respective first and second operational states of the respective first and second radio applications. There is at least one common resource among the first and second budgets. From resource allocation rules stored in the memory is determined that each of the common resources are mutually exclusive as between the first and second operational states of the respective first and second radio applications. As a result of the determining from the resource allocation rules, the request of the first radio application is granted by allocating resources according to the first budget for the first operational state while resources according to the second budget are allocated for the second operational state. | 03-31-2011 |
