A method of controlling device-to-device communications between user equipment, including using a network control element, which is common to a plurality of networks, including controlling any of the following functions: network access control functions, connection set-up, resource allocation, mode switching, handover, security and/or charging. Also a method of controlling handovers or connections in a device-to-device communications between a first and a second user equipment wherein the control is performed, at least in part, said first or second user equipments. Alternatively the user equipment may send reports a handover/connection is initiated/controlled based on said report.

Method and apparatus for device-to-device communication

A first access node of a first network utilizes code sequences, assigned to different user devices, to distinguish at least acknowledgements received in parallel or sequentially from those user devices. The first access node determines from received signaling that a root sequence of the code sequences is in use by a second access node of a second network, then changes that root sequence of the code sequences assigned to the different user devices. In certain examples the access nodes are WLAN access points APs and the acknowledgements are received in response to a group probe/poll. In various embodiments the first AP monitors its neighbors' group probes/polls to learn the root sequences/basic service sets in use in those neighbor networks, or the AP's own stations monitor and send the information in neighbor reports. This latter option can be initiated by the stations themselves, or by the AP.

A method, apparatus, and computer program for controlling device-to-device connections and associated quality-of-service parameters are presented. The quality-of-service parameters of an end-to-end connection through a plurality of different radio access networks are aligned in connection with changing a communication mode to a direct device-to-device connection.

Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: receiving by a wireless terminal device, a first message from an access point, the first message comprising information indicating a plurality of restricted access windows, each allocated for a different group of terminal devices associated to a wireless network managed by the access point; receiving by the terminal device, a second message from the access point, within a restricted access window of the plurality of restricted access windows, the restricted access window allocated to a group of terminal devices of which the terminal device is a member, the second message comprising information indicating that a communications channel is available; and determining by the terminal device, based on the second message, that the communications channel is not occupied by hidden ones of the terminal devices associated to the network.

In accordance with exemplary embodiments of the invention there is a method and apparatus to detect with a hybrid automatic repeat request function a collision between an uplink packet re-transmission and a new uplink packet transmission within a hybrid automatic repeat request process, and in response, to dynamically allocating resources for transmitting the new uplink packet transmission in a different hybrid automatic repeat request process that does not collide with the uplink packet re-transmission. In accordance with other exemplary embodiments of the invention, there is a method and apparatus to transmit a packet re-transmission in a hybrid automatic repeat request process using a semi-persistently scheduled uplink resource, and responsive to receiving a dynamic allocation of a different hybrid automatic repeat request process, to transmit a new packet using the dynamically allocated different hybrid automatic repeat request process.
