Radio interface protocol architecture aspects, quality of service (qos), and logical channep prioritization for 5g new radio

The apparatus as recited in any one of the preceding claims, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:

• determining whether a data radio bearer is mapped to more than logical channel in the plurality of logical channels;
• and
• when the data radio bearer is mapped to more than one logical channel in the plurality of logical channels, restricting at least one logical channel of the plurality of logical channels from using first grant of resources.

The apparatus as recited in any of the preceding claims, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:

• when the first grant of resource is received, establishing a counter associated with the grant;
• and
• incrementing the counter each time a predetermined unit of time expires without the first grant being used, so as to track an age of the first grant.

The apparatus as recited in any one of the preceding claims, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform further operations comprising:

• comparing a latency requirement of each of the plurality of logical channels to a latency of the first grant to identify a subset of logical channels that can use the grant, wherein the selected logical channel is one of the subset of logical channels.

The apparatus as recited in any of the preceding claims, the apparatus further comprising computer-executable instructions stored in the memory of the apparatus which, when executed by the processor of the apparatus, cause the apparatus to perform operations comprising:

• receiving a second grant of resources from the network node connected to the apparatus via the network, wherein the second grant of resources indicates a second lifetime associated with the second grant, such that the second grant is not usable when the second lifetime expires, and the first lifetime overlaps with the second lifetime.

The apparatus as recited in any one of the preceding claims, wherein the data is transmitted to the network in uplink communications.
