Abstract

Claims (61)

1. A method of performing, by a user equipment (UE), transmission in a wireless communication system, the method comprising:

receiving, by the UE, a plurality of configured grants, wherein the receiving comprises receiving a configured grant for at least one service configured in a single bandwidth part (BWP);

determining, by the UE, whether an overlap occurs between the plurality of configured grants, wherein the determining comprises determining whether transmission points for transmitting traffic are overlapped in time;

selecting, by the UE, a first configured grant from among a plurality of overlapped configured grants, wherein the selecting of the first configured grant is based on a priority for a logical channel corresponding to the first configured grant, wherein the priority is indicated by a radio resource control (RRC) message received from a base station, and wherein a second configured grant of the overlapped configured grants is ignored;

transmitting, using the first configured grant, traffic associated with the logical channel;

activating, by the UE, one of a first BWP or a second BWP that is indicated by a BWP indicator comprised in a Physical Downlink Control Channel (PDCCH) received from the base station; and

deactivating the other one of the first BWP or the second BWP that is not indicated by the BWP indicator.

2. The method of claim 1 , wherein:

the first BWP supports a plurality of services comprising a first service, a second service, and a third service;

the plurality of configured grants are associated with the plurality of services; and

at least one configured grant, of the plurality of configured grants, is configured for each of the plurality of services.

3. The method of claim 2 , wherein:

the second BWP supports a fourth service and a fifth service;

the plurality of configured grants are associated with the fourth service and the fifth service; and

at least one configured grant, of the plurality of configured grants, is configured for each of the fourth service and the fifth service.

4. The method of claim 2 , further comprising:

determining a transmission point, in time, of traffic for each of the plurality of services using the configured grants for the plurality of services of the first BWP respectively; and

determining whether transmission points of traffic overlap in time among the plurality of services.

5. The method of claim 1 , further comprising:

receiving, from the base station and using a configured scheduling radio network temporary identifier (CS-RNTI) for retransmission of a second configured grant configured for the UE, an indication of an uplink resource; and

transmitting, using the uplink resource, traffic for a service corresponding to a dropped configured grant.

6. The method of claim 5 , further comprising, for the transmitting the traffic for the service:

receiving allocation of a retransmission grant addressed to the CS-RNTI; and

determining retransmission of traffic for a corresponding service by verifying a Hybrid Automatic Repeat Request (HARQ) process identifier (ID) of the retransmission grant.

7. The method of claim 1 , wherein the first configured grant configures the UE to transmit uplink data without performing a scheduling request (SR) transmission.

8. The method of claim 1 , further comprising:

receiving, using a cell radio network temporary identifier (C-RNTI), an indication of an uplink resource from the base station; and

transmitting, using the uplink resource, traffic for a service corresponding to a dropped configured grant.

9. A method comprising:

receiving, by a wireless user device, a plurality of configured grants associated with a bandwidth part (BWP);

determining, by the wireless user device, whether an overlap occurs between the plurality of configured grants, wherein the determining comprises determining whether transmission points for transmitting traffic are overlapped in time;

based on overlapped configured grants of the plurality of configured grants, selecting, by the wireless user device, a first configured grant from the overlapped configured grants, wherein the selecting of the first configured grant is based on a priority associated with the first configured grant, and wherein the priority is indicated by a radio resource control (RRC) message received from a base station;

based on the first configured grant, transmitting, by the wireless user device, an uplink signal associated with the first configured grant;

after ignoring a second configured grant of the overlapped configured grants, receiving, from the base station and using a configured scheduling radio network temporary identifier (CS-RNTI) for retransmission associated with the ignored second configured grant, an indication of an uplink resource; and

transmitting, using the uplink resource, an uplink signal associated with the ignored second configured grant.

10. The method of claim 9 , wherein uplink resources, for Hybrid Automatic Repeat Request (HARQ) transmissions or HARQ retransmissions, are allocated via the plurality of configured grants.

11. The method of claim 9 , further comprising:

receiving allocation of a retransmission grant addressed to the CS-RNTI; and

based on a Hybrid Automatic Repeat Request (HARQ) process identifier (ID) of the retransmission grant, performing retransmission of an uplink signal.

12. The method of claim 9 , further comprising:

after ignoring a second configured grant of the overlapped configured grants, receiving, using a cell radio network temporary identifier (C-RNTI), an indication of an uplink resource from the base station; and

transmitting, using the uplink resource, an uplink signal associated with the ignored second configured grant.

13. The method of claim 9 , wherein the first configured grant configures the wireless user device to transmit uplink data without performing a scheduling request (SR) transmission.

14. A method of performing, by a user equipment (UE), transmission in a wireless communication system, the method comprising:

receiving, by the UE, a plurality of uplink grants of a bandwidth part (BWP) of a cell, wherein the plurality of configured grants comprises:

a configured grant configured by a radio resource control (RRC) reconfiguration message; and

a second uplink grant associated with an indication via a physical downlink control channel (PDCCH);

based on a transmission time duration associated with the configured grant overlapping with a transmission time duration associated with the second uplink grant, the configured grant:

selecting the second uplink grant; and

ignoring the configured grant, wherein the ignoring of the configured grant is based on a priority for a logical channel corresponding to the configured grant, and wherein the priority is indicated by a radio resource control (RRC) message received from a base station;

transmitting, using the second uplink grant, uplink data;

after ignoring the configured grant of the overlapped configured grants, receiving, from the base station and using a configured scheduling radio network temporary identifier (CS-RNTI) for retransmission associated with the ignored configured grant, an indication of an uplink resource; and

transmitting, using the uplink resource, an uplink signal associated with the ignored configured grant.

15. The method of claim 14 , wherein the configured grant configures the UE to transmit uplink data without performing a scheduling request (SR) transmission.

16. The method of claim 14 , wherein the configured grant is a configured grant of a first type; and

wherein the second uplink grant is a configured grant of a second type.

17. The method of claim 14 , further comprising:

after ignoring the configured grant, keeping data associated with the ignored configured grant;

receiving an indication of an uplink resource from the base station; and

transmitting, using the uplink resource, the kept data associated with the ignored configured grant.

18. The method of claim 17 , wherein the indication of the uplink resource is received using the CS-RNTI.
