Abstract: An apparatus is provided in a communications device. The apparatus comprises at least one processor and at least one memory including computer code for one or more programs. The at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to determine that at least one of a plurality of logical channels configured for packet duplication is to be deactivated; and determine an allocation of one or more cells associated with the at least one deactivated logical channel to one or more active logical channels of said plurality of logical channels configured for packet duplication.

Abstract: Embodiments of the present disclosure relate to contention resolution in random access procedure. An apparatus transmits a random access request to a further apparatus, and the random access request comprises a random access preamble and an identifier of the apparatus for a random access procedure. The apparatus then receives, from the further apparatus, control information on a control channel addressed to the identifier, and the control information indicates at least one of a resource and timing information for communication between the apparatus and the further apparatus. Next, the apparatus determines a result of the random access procedure based at least in part on the control information.

Abstract: In accordance with the example embodiments of the invention there is at least a method and apparatus to perform determining, by a device of a communication network, that at least one PDCP PDU of a PDCP sublayer is duplicated for transmission over at least one logical channel; signaling to an RLC sublayer an indication of the at least one PDCP PDU that is duplicated; and based on the signaling, controlling duplication of the at least one PDCP PDU for transmission over the at least one logical channel. Further, there is at least a method and apparatus to perform receiving, at a device of a communication network, an indication through a received signaling indicating that at least one PDCP PDU of a PDCP sublayer is to be duplicated; determining to duplicate the at least one PDCP PDU; duplicating the at least one PDCP PDU based on the determination; and transmitting the duplicated PDCP PDU over at least one logical channel.

Abstract: A method includes transmitting information from an apparatus regarding at least one operating band combination. The information regarding the at least one operating band combination may comprise at least one of an index comprising a plurality of operating band combinations, and a bitmap relating to the index of operating band combinations. The method also includes selecting by the apparatus either a supported indicator or an unsupported indicator regarding the information. The method further includes transmitting, by the apparatus, the selected indicator.

Abstract: Various communication systems may benefit from parallel preamble transmissions. In particular, communication systems of the long term evolution of the third generation partnership project may benefit from methods and systems for parallel preamble transmission in power limited situations. A method can include determining at a physical layer of a device that a predetermined condition has been met with respect to a power limited situation. The method can also include communicating an indication that the predetermined condition has been met to a higher layer of the device based on the determining that the predetermined condition has been met.
