Wireless resource determination and use
Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.
1. A method comprising:
receiving, by a wireless device during a physical downlink control channel (PDCCH) monitoring occasion of one cell, downlink control information (DCI) indicating:
scheduling information for a plurality of transport blocks (TBs) for reception in a plurality of downlink time slots; and
an uplink time slot for transmission of hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with each of the plurality of TBs;
determining a physical uplink control channel (PUCCH) resource associated with a latest starting time of the plurality of downlink time slots; and
transmitting, via the PUCCH resource, the HARQ-ACK information.
2. The method of claim 1 , wherein the DCI comprises a plurality of DCI messages, and wherein each DCI message of the plurality of DCI messages comprises an indication of the uplink time slot for transmission of the HARQ-ACK information.
3. The method of claim 1 , further comprising:
ordering the DCI based on starting times of the plurality of downlink time slots; and
determining, based on the ordering, the latest starting time of the plurality of downlink time slots, wherein the PUCCH resource is indicated by the DCI having the latest starting time of the plurality of downlink time slots.
4. The method of claim 1 , wherein the determining the PUCCH resource is based on at least one of:
a priority parameter; or
a service type.
5. The method of claim 1 , wherein the scheduling information for the plurality of TBs is for cross-carrier scheduling, via the one cell, the plurality of TBs for transmission via a scheduled cell, and wherein a subcarrier spacing of the one cell is lower than a subcarrier spacing of the scheduled cell.
6. The method of claim 1 , wherein the transmitting the HARQ-ACK information comprises transmitting the HARQ-ACK information in the uplink time slot indicated by the DCI.
7. The method of claim 1 , wherein the receiving the DCI during the PDCCH monitoring occasion of the one cell comprises receiving a plurality of DCI messages during a same PDCCH monitoring occasion of at least one of:
a same slot;
a same subframe; or
a same time interval.
8. A method comprising:
receiving, by a wireless device during a physical downlink control channel (PDCCH) monitoring occasion of one cell, a plurality of downlink control information (DCI) messages, wherein each DCI message of the plurality of DCI messages indicates:
scheduling information for a corresponding transport block (TB) to be transmitted in a downlink time slot of a plurality of downlink time slots; and
an uplink time slot for transmission of hybrid automatic repeat request acknowledgment (HARQ-ACK) information associated with a plurality of TBs;
determining a physical uplink control channel (PUCCH) resource associated with a latest starting time of the plurality of downlink time slots; and
transmitting, via the PUCCH resource, the HARQ-ACK information.
9. The method of claim 8 , further comprising:
ordering the DCI messages based on starting times of the plurality of the downlink time slots; and
determining, based on the ordering, the latest starting time of the plurality of the downlink time slots.
10. The method of claim 8 , wherein the determining the PUCCH resource is based on at least one of:
a priority parameter; or
a service type.
11. The method of claim 8 , wherein the scheduling information for the corresponding TB is for cross-carrier scheduling, via the one cell, the corresponding TB for transmission via a scheduled cell, and wherein a subcarrier spacing of the one cell is lower than a subcarrier spacing of the scheduled cell.
12. The method of claim 8 , wherein the transmitting the HARQ-ACK information comprises transmitting the HARQ-ACK information in the uplink time slot indicated in each DCI message of the plurality of DCI messages.
13. The method of claim 8 , wherein the receiving the plurality of DCI messages during the PDCCH monitoring occasion of the one cell comprises receiving the plurality of DCI messages during a same PDCCH monitoring occasion of at least one of:
a same slot;
a same subframe; or
a same time interval.
14. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive, during a physical downlink control channel (PDCCH) monitoring occasion of one cell, downlink control information (DCI) indicating:
scheduling information for a plurality of transport blocks (TBs) for reception in a plurality of downlink time slots; and
an uplink time slot for transmission of hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with each of the plurality of TBs;
determine a physical uplink control channel (PUCCH) resource associated with a latest starting time of the plurality of downlink time slots; and
transmit, via the PUCCH resource, the HARQ-ACK information.
15. The wireless device of claim 14 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to:
order the DCI based on starting times of the plurality of downlink time slots; and
determine, based on the order, the latest starting time of the plurality of downlink time slots, wherein the PUCCH resource is indicated by the DCI having the latest starting time of the plurality of downlink time slots.
16. The wireless device of claim 14 , wherein the instructions, when executed by the one or more processors, cause the wireless device to determine the PUCCH resource by determining the PUCCH resource further based on at least one of:
a priority parameter; or
a service type.
17. The wireless device of claim 14 , wherein the scheduling information for the plurality of TBs is for cross-carrier scheduling, via the one cell, the plurality of TBs for transmission via a scheduled cell, and wherein a subcarrier spacing of the one cell is lower than a subcarrier spacing of the scheduled cell.
18. The wireless device of claim 14 , wherein the instructions, when executed by the one or more processors, cause the wireless device to transmit the HARQ-ACK information by transmitting the HARQ-ACK information in the uplink time slot indicated by the DCI.
19. The wireless device of claim 14 , wherein instructions, when executed by the one or more processors, cause the wireless device to receive the DCI during the PDCCH monitoring occasion of the one cell by receiving a plurality of DCI messages during a same PDCCH monitoring occasion of at least one of:
a same slot;
a same subframe; or
a same time interval.
20. The wireless device of claim 14 , wherein the DCI comprises a plurality of DCI messages, and wherein each DCI message of the plurality of DCI messages comprises an indication of the uplink time slot for transmission of the HARQ-ACK information.
