Abstract: The present disclosure relates to methods for selecting or reselecting a cell from among a plurality of cells. The present disclosure is also providing mobile stations for performing these methods, and computer readable media the instructions of which cause the mobile station to perform the methods described herein. For this purpose, the mobile station is detecting cells which are candidates (i.e. candidate cells) for selection or reselection, utilizing either the normal coverage mode or the enhanced coverage mode. Further, the mobile station is selecting or reselecting a cell among the candidate cells detected, utilizing either the normal coverage mode or the enhanced coverage mode. The mobile station is performing the detection and the selection or reselection on the basis of stored information indicating whether or not at least one of the candidate cells supports that the detection and the selection or reselection utilize the enhanced coverage mode.

Abstract: The invention relates to a method for discovery of one or more relay user equipments within a mobile communication network. A relay user equipment is capable to perform direct communication over a direct sidelink connection respectively with one or more remote user equipments, and is further capable to serve as a relay respectively for the one or more remote user equipments to relay communication between the one or more remote user equipments and the radio base station. The relay user equipment determines whether an overload situation exists in the relay user equipment or not, the overload situation preventing the relay user equipment to serve as a relay for a further remote user equipment. The relay user equipment transmits a relay discovery message, at least comprising an overload indication providing information on the result of the determination as to whether the overload situation exists in the relay user equipment.

Abstract: The layer processing includes at least processing on a first, a second and a third layer. At the transmitter side, the third layer receives a packet, adds its header and forwards the packet to the second layer. The second layer performs segmentation and provides segmented data to the first layer, which maps the segmented data onto physical resources. The segmentation is based on the allocated resources. Retransmissions may take place on the third layer and thus, the third layer may re-segment the packet according to the received feedback for particular segments and provide the re-segmented data to the lower layers. Alternatively, the feedback information is provided to the second layer which then performs the segmentation by taking it into account. Correspondingly, the receiver performs re-ordering and re-assembly at the third layer for which it receives also control information from the second layer.

Abstract: The invention relates to an improved handover procedure for a mobile terminal. Under control of the target base station, the mobile terminal is to perform a handoff to a target base station, wherein it is to be configured for communication with the target base station via a target radio cell comprising a downlink carrier and an uplink carrier. The mobile terminal receives a handoff command message for the handoff to the target base station including a handoff execution condition as trigger for executing handoff to the target base station. Then, the mobile terminal determines, based on the received handoff execution condition, whether or not the mobile terminal is to trigger execution of the handoff to the target base station. In case the mobile terminal determines that it is to trigger execution of the handoff to the target base station, the mobile terminal executes the handoff to the target base station.

Abstract: The present disclosure relates to transmitting data over a physical uplink shared channel in a wireless communication system by using an asynchronous hybrid automatic repeat request, HARQ. An exemplary apparatus comprises a first timer configured to start upon uplink data transmission and stop after a first predetermined time; a second timer configured to start upon stop of the first timer and to stop after a second predetermined time; a receiver for receiving downlink control information including a positive acknowledgement for uplink new data transmission or retransmission, the receiver being configured to perform the receiving only when the first timer is stopped and the second timer is running, wherein the second timer is further configured to stop upon receiving the positive acknowledgement. Moreover, an apparatus for receiving the data and transmitting the control channel is provided as well as the corresponding transmitting and receiving method.

Abstract: The invention relates to an improved transmission protocol for uplink data packet transmission. A transmission counter of the transmission protocol counts the number of transmissions the user terminal has performed for a data packet. The user terminal participates in sidelink discovery operation with other user terminals based on sidelink discovery gaps. The user terminal cannot transmit and/or receive signals under control of the transmission protocol when participating in sidelink discovery operation during the sidelink discovery gaps. A processor of the user terminal determines whether a retransmission of a data packet, which is triggered by the transmission protocol, was not performed because the transmission protocol operation collided with one of the sidelink discovery gaps. In case of collision, the processor operates the transmission counter such that the colliding retransmission of the data packet does not result in an increment of the transmission counter of the transmission protocol for the data packet.

Abstract: The disclosure relates to a method for performing a random access procedure between a user equipment and a radio base station. The UE is configured with at least one unlicensed cell having an unlicensed cell frequency, via which the UE performs the random access procedure bandwidth. A minimum frequency bandwidth threshold is defined for transmissions via the unlicensed cell. The user equipment selects a random access preamble sequence for the random access procedure. A frequency bandwidth is determined by the UE for transmitting the random access preamble sequence via the unlicensed cell, the determined frequency bandwidth of the random access preamble sequence being at least the minimum frequency bandwidth threshold. The UE then transmits the random access preamble sequence to the radio base station such that at least the determined frequency bandwidth of the unlicensed cell is occupied.

Abstract: The invention relates to methods for reporting on downlink timings by a mobile terminal in a mobile communication system. In order to allow for an aggregation access point to obtain information on propagation delay differences of downlink transmissions on aggregated serving cells, the invention suggests the mobile terminal to report timing information based on reception time difference information for a the target/reference cell. The mobile terminal performs measurements relating to transmission and/or reception time differences on the target/reference cell, and reports same to the eNodeB. The eNodeB compares the measurement result to a predefined maximum propagation delay time difference. Alternatively, the mobile terminal performs the measurements, compares same to the predefined maximum propagation delay time difference and then report the comparison result to the eNodeB.
