Downlink control information to support uplink partial subframe transmission on licensed assisted access secondary cell
Briefly, in accordance with one or more embodiments, an apparatus of an evolved Node B (eNB) or a next generation Node B (gNB) comprises one or more baseband processors to encode downlink control information (DCI) to be transmitted in a physical downlink control channel (PDCCH) to a user equipment (UE) to schedule an uplink subframe including partial uplink subframe information, and to decode the scheduled uplink subframe from a physical uplink shared channel (PUSCH) received from the UE, and a memory to store the partial uplink subframe information.
1. An apparatus of an evolved Node B (eNB) or a next generation Node (gNB), comprising:
one or more baseband processors configured to:
encode downlink control information (DCI) to be transmitted in a physical downlink control channel (PDCCH) to a user equipment (UE) to schedule an uplink subframe including partial uplink subframe information, and
decode the scheduled uplink subframe from a physical uplink shared channel (PUSCH) received from the UE, wherein the DCI information indicates a duration of an uplink burst and whether the uplink burst accommodates one or more partial uplink subframes; and
a memory to store the partial uplink subframe information.
2. The apparatus of claim 1 , wherein the DCI comprises format 0A/4A and indicates whether the scheduled subframe is a partial uplink subframe.
3. The apparatus of claim 2 , wherein the DCI indicates whether the scheduled subframe is a starting partial uplink subframe or and ending partial uplink subframe.
4. The apparatus of claim 2 , wherein the DCI indicates a duration of the partial subframe.
5. The apparatus of claim 1 , wherein the DCI comprises format 0B/4B and indicates whether the scheduled subframe is partial uplink subframe.
6. The apparatus of claim 5 , wherein the DCI indicates whether the schedule subframe is starting partial uplink subframe or an ending partial uplink subframe of multiple scheduled subframes.
7. The apparatus of claim 5 , wherein the DCI indicates a duration of one or more partial uplink subframes.
8. The apparatus of claim 1 , wherein the partial uplink subframe preceded by a partial downlink subframe in a same subframe is counted and signaled as one subframe in the uplink burst duration to support an offset of 0.
9. The apparatus of claim 1 , wherein the partial uplink subframe preceded by a partial downlink subframe in a same subframe is not counted as one subframe in the uplink burst duration.
10. The apparatus of claim 1 , wherein if the partial uplink subframe is not preceded by partial downlink subframe in a same subframe, the partial uplink subframe is counted as one subframe in the uplink burst duration.
11. The apparatus of claim 1 , wherein if the partial uplink subframe is not preceded by a partial downlink subframe in a same subframe, the partial uplink subframe is not counted towards the uplink burst duration.
12. The apparatus of claim 1 , wherein if the partial uplink subframe follows a partial downlink subframe in a same subframe, the partial uplink subframe is not counted towards the uplink burst duration.
13. The apparatus of claim 1 , wherein if the partial uplink subframe does not follow a partial downlink subframe in a same subframe, the partial uplink subframe is counted towards the uplink burst duration.
14. A user equipment (UE), comprising:
radio frequency circuitry configured to communicate with a base station; and
one or more baseband processors configured to:
decode downlink control information (DCI) received from the base station in a physical downlink control channel (PDCCH), the DCI comprising schedule information for an uplink subframe including a duration of an uplink burst and whether the uplink burst accommodates one or more partial uplink subframes, and
transmit the scheduled uplink subframe in a physical uplink shared channel (PUSCH).
15. The UE of claim 14 , wherein the partial uplink subframe preceded by a partial downlink subframe in a same subframe is counted and signaled as one subframe in the uplink burst duration to support an offset of 0.
16. The UE of claim 14 , wherein the partial uplink subframe preceded by a partial downlink subframe in a same subframe is not counted as one subframe in the uplink burst duration.
17. The UE of claim 14 , wherein if the partial uplink subframe is not preceded by partial downlink subframe in a same subframe, the partial uplink subframe is counted as one subframe in the uplink burst duration.
18. The UE of claim 14 , wherein if the partial uplink subframe is not preceded by a partial downlink subframe in a same subframe, the partial uplink subframe is not counted towards the uplink burst duration.
19. The NE of claim 14 , wherein if the partial uplink subframe follows a partial downlink subframe in a same subframe, the partial uplink subframe is not counted towards the uplink burst duration.
20. The UE of claim 14 , wherein the DCI indicates whether the scheduled subframe is a starting partial uplink subframe or and ending partial uplink subframe.
