Abstract: A scheduling method for use in a radio access network to allocate frequency resources to a user device for the transmission of data units organized in a set of data units is disclosed. The sets of data units are assigned an initial transmission delay budget which decreases over time. The scheduling method includes, at a given transmission time, prioritizing scheduling the user device with the largest portion of data units already successfully transmitted within the set of data units, and prioritizing scheduling the user device which set of data units has the smallest remaining transmission delay budget.

Abstract: A method, computer program, and apparatus for causing an apparatus to perform: determining, by an RLC layer of the apparatus from an indication received from a MAC and/or PHY layer of the apparatus, that a retransmission procedure of a data packet comprising at least one service data unit of the set of service data units has been completed without the at least one service data unit being successfully received; causing at least one of a first RLC entity or a second RLC entity maintained by the apparatus to determine whether at least one trigger event occurs based on the determining; and when the first RLC entity and/or the second RLC entity determines that the at least one trigger event has occurred, signalling to a transmitter of the data packet an indication that the at least one service data unit has not been successfully received by the RLC layer.

Abstract: A method is provided that includes receiving, at a layer of a radio protocol stack, a first uplink unit of data from a higher layer of the radio protocol stack. The first uplink unit of data is in a set of one or more first uplink units of data, and the set is marked with information including an importance value associated with the set that identifies a relative importance of the set compared to other sets within a quality of service flow. The method includes constructing a second uplink unit of data from the first uplink unit of data. And the method includes making a determination to submit the second uplink unit of data to a lower layer of the radio protocol stack, or buffer the second uplink unit of data, based on the importance value associated with the set, and a threshold importance value.

Abstract: A method includes transmitting, by a network apparatus to a user equipment (UE) based on a first condition, a first command to activate a protocol data unit set importance (PSI)-based discard at the UE, where the PSI-based discard includes discarding a protocol data unit (PDU) set based on a PSI level of the PDU set satisfying a PSI criterion, and where the PDU set includes one or more PDUs carrying a payload of one unit of information at an application level; and transmitting, by the network apparatus to the UE based on a second condition, a second command to cancel the PSI-based discard at the UE.

A method may include receiving from a network element, at least one transport block including at least one coding block group. The method may also include determining which of the at least one transport block and the at least one coding block group was correctly or incorrectly received. The method may further include transmitting, based on the determination, a first report which identifies transport blocks of the at least one transport block that was correctly received and incorrectly received. In addition, the method may include, upon determining that at least one of the transport blocks was received incorrectly, transmitting a second report identifying coding block groups of the at least one coding block group that was incorrectly received from the transport blocks that were incorrectly received.

Abstract: For a network node in wireless communication with a UE, filling a TB such that at least two data with different reliability requirements are mapped to separate CBs. The network node applies different MCSs to at least the separate CBs comprising the data with different reliability requirements within the transport block. The network node transmits the TB toward the UE after the different MCSs have been applied. The UE can use a similar technique in UL in order to transmit. The UE may also receive the TB from the network node. The UE decodes and performs error checking of the CBs based on the corresponding MCSs that were applied.
