摘要:
This document discloses a solution for controlling measurements of a terminal device. According to an aspect, a method comprises: determining, on the basis of measurement data measured from a radio link, a distance between an access node and a terminal device and angular motion of the terminal device with respect to the access node; making a decision about a length of a time interval between consecutive radio measurements of the terminal device on the basis of the distance and the angular motion; and communicating the decision over the radio link.
摘要:
Methods, apparatuses, and systems are provided for facilitating device-to-device connection establishment. A method may include directing broadcast of an indication of a device-to-device registration area identification in each of one or more cells forming a device-to-device registration area identified by the device-to-device registration area identification. The method may further include directing receipt of a device-to-device registration request originated by a first terminal apparatus in response to the broadcast indication. The first terminal apparatus may be located within the registration area. The method may additionally include registering the first terminal apparatus based at least in part upon the device-to-device registration request. Corresponding apparatuses and systems are also provided.
摘要:
There is provided a method comprising receiving, at a user device, control information usable for determining whether at least one uplink logical channel is to be transmitted using at least one of a first uplink transport channel and a second uplink transport channel, determining, in dependence on said information, a mapping between the at least one uplink logical channel and at least one of the first uplink transport channel and second uplink transport channel and causing the at least one uplink logical channel to be transmitted using the at least one uplink transport channel to which the at least one uplink logical channel is mapped.
摘要:
There is provided a method comprising determining, for a service data unit to be included in a protocol data unit, whether a segment of the service data unit is to be included in the protocol data unit and, if so, determining the position of the segment relative to the service data unit, the protocol data unit comprising a header part and a data field part, determining whether to include information in the header part in dependence of the first determining, and, if so, determining the content of the information in dependence on the first determining and providing the protocol data unit to a receiver entity.
摘要:
An apparatus is disclosed that performs operations including determining whether an application message meets a predetermined set of criteria. If the application message meets the set, the application message is transmitted via a first communication layer pathway between the apparatus and one or more other apparatuses participating in a device-to-device communication with the apparatus. If the application message does not meet the set, the application message is transmitted via a second communication layer pathway between the apparatus and the other apparatus. The first and second communication layer pathways are different. The first pathway may be an L1 physical control channel while the second pathway may be an L1 physical data channel. The first pathway may be a first L2 logical channel while the second pathway may be a second L2 logical channel. Methods and program products are also disclosed.
