摘要:
A method, apparatus and computer program product are provided to efficiently establish communications regardless of the radio resource control (RRC) state of the device that issues the discovery signal. In regards to a method, a cell identification and/or tracking area code is associated with a discovery signal. Thereafter, the method causes a discovery signal to be transmitted to discover another device with which to establish communications. The method also receives a paging signal in response to the discovery signal and causes communications to be established in response to the paging signal. By associating a cell identification and/or a tracking area code with at least part of the discovery signal, the paging signals may be focused in the cell and/or tracking area in which the device that issued the discovery signal is located, even when the device is in an RRC Idle state.

There is provided a mechanism for registering and attaching a UE to a D2D discovery function. After identifying an ID information of at least one PLMN assigned for a D2D discovery and communication, a request for registering and attaching the UE to the D2D discovery function at the identified PLNM is sent to the network. The network sends a grant for the D2D discovery together with an indication corresponding to an identity of the at least one PLMN used for communicating resources dedicated to the D2D discovery and communication.

A method and apparatus for providing allocating efficient resource allocation for device-to-device (D2D) communications. Various bandwidth allocations are provided which provide for D2D discovery information to be included on a time slot, such as an uplink pilot time slot (UpPTS). By accommodating D2D discovery information on un-used available bandwidth, the base station may efficiently configure and assign radio resources for D2D and cluster communication purposes in its coverage area.

There is proposed a mechanism for validating a communication device such as a UE for allowing usage of television radio bands/channels (TVWS). An identification verification process of the communication device is performed by including a unique identification element into an integrity protected and ciphered message related to a radio resource connection reconfiguration procedure, the unique identification element identifying a certified communication device allowed to use radio resources of a television radio band. The message is transmitted to the communication network for performing an identification verification processing with a TVWS database. Furthermore, a mechanism for a handover scenario is provided where validating of the communication device for allowing usage of television radio bands/channels (TVWS) is performed.

摘要:
In a multi-RAT user equipment autonomous denials are used to stop LTE transmission to free frames or subframes for the transmission of e.g Bluetooth or WLAN signals. The use of the autonomous denials is limited per defined time period. The start of this time window may not be synchronised between UE and eNB. To avoid any synchronisation problems, a system frame number associated with the network entity is used as the basis for generating an indicator for the start of the time period. The indicator is then transmitted to the user equipment, which is adapted to respond to receipt of the indicator by configuring the user equipment to perform no more than a predetermined number of autonomous denials during the time period. The number of unsuccessful transmissions during the time period is then monitored by the network entity, and resource usage within the wireless communications network is selectively adapted on the basis of the monitoring.

A solution for uplink transmission in a cellular communication system is disclosed. The same uplink time-frequency resource are scheduled to at least two terminal devices, and sensing periods of unequal lengths are allocated to the at least two terminal devices. The sensing period defines a duration a terminal device senses the uplink time-frequency resource for a conflicting transmission before transmitting in the uplink time-frequency resource.

The present invention discloses an apparatus, a method and a computer program for mapping and allocating available television white space channels for a terminal requesting resources. The mapping is based on the data of available overlapping TV white space channels within a geographical tracking area and coexistence with other cellular secondary systems within the area. Furthermore, a location for a moving mode II device may be tracked periodically. The geo-location accuracy of the mode II device affects the TV white space resources which can be allocated to the device.
摘要:
A method and apparatus are provided to facilitate the selection of a monitoring device for a communication link in device-to-device communications, such as non-cellular communications or cellular communications in a licensed exempt band. A method and apparatus determine the reception resources available for use by a first telecommunications device, and ascertain the reception resources available for use by a second telecommunications device. The method and apparatus then select either the first telecommunications device or the second telecommunications device as a monitoring device to monitor the communications link. The method and apparatus may also change the monitoring device to the other telecommunications device based upon a change in the balance of reception resources of the first telecommunications device or the second telecommunications device.
