Abstract

Disclosed herein are new radio (NR) Data link architecture options including, for example, NR radio bearer models, NR logical channel models, and MAC and HARQ models. Further described are packet flows mapping to data radio bearers (DRBs), and a new flow encapsulation protocol in the user plane. In some embodiments, DRBs with different quality of service (QoS) are pre-established, but not activated. This allows a given user equipment (UE) to use these DRBs for packet data network (PDN) flows without a large overhead. Pre-established DRBs can be an extension to default bearer concept with the decision of pre-establishment of DRBs based on UE capability, subscription profile, operation policy, installed apps, etc.

First claim

What is claimed:

1 . An apparatus comprising a processor, a memory, and communication circuitry, the apparatus comprising a plurality of logical channels configured to connect to a network via its communication circuitry, 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 first grant of resources from a network node connected to the apparatus via the network, wherein the first grant of resources indicates a first lifetime associated with the first grant, such that the first grant is not usable when the first lifetime expires; based on the lifetime associated with the first grant, selecting a logical channel of the plurality of logical channels of the apparatus; and transmitting data over the selected logical channel using the first grant of resources.

2 . The apparatus as recited in claim 1 , wherein the first grant of resources further indicates a numerology associated with the first grant of resources, and the selected logical channel is further selected based on the numerology.

3 . 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.

4 . 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.

5 . 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.

6 . The apparatus as recited in claim 5 , wherein the selected logical channel is selected from the subset of logical channels based on a predetermined prioritization of the logical channels, the predetermined prioritization based on at least one of the latency requirement of the selected logical channel or a quality of service requirement of the selected logical channel.

7 . 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.

8 . The apparatus as recited in claim 7 , 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:
making a determination that the second lifetime will expire before the first lifetime; and based on the determination, using the second grant of resources instead of the first grant of resources to transmit data over one of the plurality of logical channels.

9 . The apparatus as recited in claim 7 , 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:
interrupting the transmitting of the data over the selected logical channel using the first grant of resources to transmit the data over another logical channel using the second grant of resources; and after the second grant of resources expires, resuming the transmitting of the data over the selected logical channel.

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

11 . The apparatus as recited in any one of claims 1 to 9 , wherein the data is transmitted to another apparatus in device-to-device communications.

12 . An apparatus comprising a processor, a memory, and communication circuitry, the apparatus configured to connect to a network via its communication circuitry, 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 first data packet that includes a mark that identifies a quality of service profile associated with the data packet; based on the quality of service profile, selecting a destination for transmitting the packet; and transmitting the data packet to the destination, wherein the data packet includes the mark.

13 . The apparatus as recited in claim 12 , wherein the data packet is received in a downlink communication in the network, and the destination comprises an upper layer service access point of the apparatus.

14 . The apparatus as recited in claim 12 , wherein the data packet is received from an upper layer service access point of the apparatus, and the apparatus further comprises 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:
based on the quality of service profile, selecting a data radio bearer for transmitting the packet, thereby selecting the destination; and transmitting the data packet to the destination over the selected data radio bearer.

15 . An apparatus comprising a processor, a memory, and communication circuitry, the apparatus configured to connect to a network via its communication circuitry, 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 first packet in a first direction in the network, the packet including a mark that identifies a quality of service profile associated with the first packet; receiving a second packet in a second direction in the network that is opposite the first direction; identifying a filter in the second packet and determining that the filter is associated with the mark in the first packet; and based on determining that the filter is associated with the mark, inserting the mark in the second packet and transmitting t
