It is provided a method, comprising instructing a sender to transmit a first packet data unit to a receiver on a first active bandwidth part of a carrier at a first transmission time; determining a delay and a second bandwidth part of the carrier based on a switching rule; wherein the switching rule defines that the second bandwidth part is different from the first bandwidth part; and the method further comprises instructing, if the sender is instructed to transmit the first packet data unit, the sender to transmit a second packet data unit to the receiver on the second active bandwidth part at a second transmission time after the delay after the instructing to transmit the first packet data unit has elapsed.

Preconfigured radio link switching for bandwidth parts

In accordance with some example embodiments, an apparatus may comprise at least one processor and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to transmit at least one parameter configuration of a random access channel procedure to a user equipment; receive at least one physical uplink shared channel part of a first random access channel message using at least one transmitter beam configuration; upon detection of at least one preamble part of the first random access channel message, decode the physical uplink shared channel part of the first random access channel message and perform at least one channel quality measurement on at least one demodulation reference signal sequence transmitted on a number of selected transmitter beam configurations.

Rach-based Tx beam refinement procedure

It is provided a method, comprising instructing a first cell to transmit a first packet data unit to a terminal on a first active bandwidth part of a first carrier of the first cell in a first frame and to instruct a second cell to transmit a second packet data unit to the terminal on a second active bandwidth part of a second carrier of the second cell in a second frame; wherein the first and second bandwidth parts have first and second bandwidth part identifiers, respectively; if the first cell is the same as the second cell: the first and second bandwidth part identifiers are different from each other, and the first and second system frame numbers are the same; and if the first cell is different from the second cell: a frequency range of the first carrier is the same as the frequency range of the second carrier.

Bandwidth part aggregation for reliability boost

Systems, methods, apparatuses, and computer program products for packet combining for PDCP duplication, e.g., in ultra-reliable low-latency-communication (URLLC) scenarios are provided. One method may include providing, from a network node to at least one second node, a pointer to an earlier or first transmission of a protocol data unit (PDU). The pointer may be used by subsequent transmissions of the protocol data unit (PDU) through the at least one second node to indicate to a user equipment (UE) what transmissions are to be combined.
