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: Various communication systems may benefit from improved random access operations. For example, certain embodiments may benefit from improved random access in which multiple bandwidth parts are configured to a user equipment within one cell. A method, in certain embodiments, may include triggering a random access procedure at a user equipment. The method may also include switching at the user equipment from a first uplink bandwidth part that does not support a random access channel to a second uplink bandwidth part that has the random access channel configured after the triggering of the random access procedure. The switching may be autonomously performed by the user equipment. In addition, the method may include performing the random access procedure at the user equipment using the random access channel configured at the second uplink bandwidth part.

Abstract: Various communication systems may benefit from an enhanced radio link control status report. A method may include determining a negative acknowledgment sequence number range. The negative acknowledgment sequence number range may include a plurality of consecutive radio link control missing sequence numbers. The method may also include determining at least one of a negative acknowledgment end sequence number when the plurality of consecutive radio link control missing sequence numbers exceeds the negative acknowledgment sequence number range. In addition, the method may include sending a radio link control status report comprising at least one of a negative acknowledgment sequence number, the negative acknowledgment sequence number range, or the negative acknowledgment end sequence number when the plurality of consecutive radio link control missing sequence numbers exceeds the at least one negative acknowledgment sequence number range.

Abstract: Embodiments of the present disclosure relate to a method, device and computer readable storage media for optimizing buffer state report (BSR) for limited traffic mix. In example embodiments, whether a short or long B SR being reported is up to the configuration of LCG or the configuration of LCH within the LCG. In this way, minimum overhead for low bit rate services can be kept and thus a good coverage can be achieved, while the reporting information can be increased for other traffic.

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: 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.
