Abstract

Claims (38)

1. A method, comprising:

receiving, at a user equipment, configuration information for more than one serving cell for a physical uplink control channel transmission within at least one physical uplink control channel cell group;

receiving configuration information comprising a time-domain pattern of a single physical uplink control channel cell within the at least one physical uplink control channel cell group;

determining a cell for the physical uplink control channel transmission of an uplink control information transmission based on the configured time-domain pattern;

multiplexing uplink control information and determining a physical uplink control channel resource according to the configuration information used on the determined cell for the physical uplink control channel transmission;

checking a validity of the determined physical uplink control channel resource on the determined cell for the physical uplink control channel transmission; and

transmitting the uplink control information on a physical uplink control channel or a physical uplink shared channel when the physical uplink control channel resource is valid,

wherein one of cells within the at least one physical uplink control channel cell group serves as a timing reference cell whose slot or sub-slot configuration is used to determine a timing from physical downlink shared channel transmission to hybrid automatic repeat request-acknowledgment transmission according to a timing parameter in downlink control information that schedules a physical downlink shared channel or activates a semi-persistent scheduling physical downlink shared channel transmission.

2. An apparatus, comprising:

at least one processor; and

at least one memory comprising computer program code that, when is executed by the at least one processor, causes the apparatus at least to:

receive configuration information for more than one serving cell for a physical uplink control channel transmission within at least one physical uplink control channel cell group;

receive configuration information comprising a time-domain pattern to determine a single physical uplink control channel cell within the at least one physical uplink control channel cell group;

determine a cell for the physical uplink control channel transmission of an uplink control information transmission based on the configured time-domain pattern;

multiplex uplink control information and determine a physical uplink control channel resource according to the configuration information used on the determined cell for the physical uplink control channel transmission;

check a validity of the determined physical uplink control channel resource on the determined cell for the physical uplink control channel transmission; and

transmit the uplink control information on a physical uplink control channel or a physical uplink shared channel when the physical uplink control channel resource is valid,

wherein one of cells within the at least one physical uplink control channel cell group serves as a timing reference cell whose slot or sub-slot configuration is used to determine a timing from physical downlink shared channel transmission to hybrid automatic repeat request-acknowledgment transmission according to a timing parameter in downlink control information that schedules a physical downlink shared channel or activates a semi-persistent scheduling physical downlink shared channel transmission.

3. The apparatus of claim 2 , wherein the reference cell is implicitly determined or explicitly configured by a network node.

4. The apparatus of claim 3 , wherein when the reference cell is implicitly determined, the implicitly determined reference cell comprises a primary cell or a physical uplink control channel secondary cell of the at least one physical uplink control channel cell group.

5. The apparatus of claim 3 , wherein when the reference cell is implicitly determined, the implicitly determined reference cell comprises an uplink serving cell with a lowest or highest serving cell index.

6. The apparatus of claim 3 , wherein the implicitly determined reference cell comprises an uplink serving cell applicable for the physical uplink control channel transmission with a highest subcarrier spacing, and wherein, when there is more than one cell having the highest subcarrier spacing, the uplink serving cell with a lowest or highest serving cell index is used.

7. The method according to claim 1 , wherein the reference cell is implicitly determined or explicitly configured by a network node.

8. The method according to claim 7 , wherein when the reference cell is implicitly determined, the implicitly determined reference cell comprises a primary cell or a physical uplink control channel secondary cell of the at least one physical uplink control channel cell group.

9. The method according to claim 7 , wherein when the reference cell is implicitly determined, the implicitly determined reference cell comprises an uplink serving cell with a lowest or highest serving cell index.

10. The method according to claim 7 , wherein the implicitly determined reference cell comprises an uplink serving cell applicable for the physical uplink control channel transmission with a highest subcarrier spacing, and wherein, when there is more than one cell having the highest subcarrier spacing, the uplink serving cell with a lowest or highest serving cell index is used.

11. A non-transitory computer readable medium encoded with instructions that, when is executed by a processor, perform a process, the process comprising:

receiving configuration information for more than one serving cell for a physical uplink control channel transmission within at least one physical uplink control channel cell group;

receiving configuration information comprising a time-domain pattern to determine a single physical uplink control channel cell within the at least one physical uplink control channel cell group;

determining a cell for the physical uplink control channel transmission of an uplink control information transmission based on the configured time-domain pattern;

multiplexing uplink control information and determining physical uplink control channel resource according to the configuration information used on the determined cell for the physical uplink control channel transmission;

checking a validity of the determined physical uplink control channel resource on the determined cell for the physical uplink control channel transmission; and

transmitting the uplink control information on a physical uplink control channel or a physical uplink shared channel when the physical uplink control channel resource is valid,

wherein one of cells within the at least one physical uplink control channel cell group serves as a timing reference cell whose slot or sub-slot configuration is used to determine a timing from physical downlink shared channel transmission to hybrid automatic repeat request-acknowledgment transmission according to a timing parameter in downlink control information that schedules a physical downlink shared channel or activates a semi-persistent scheduling physical downlink shared channel transmission.

12. The non-transitory computer readable medium according to claim 11 , wherein the reference cell is implicitly determined or explicitly configured by a network node.
