Power control and retransmission
Wireless communications are described for controlling a transmission. A base station may cancel, delay, and/or request a retransmission of a message. The base station may send a control message to control a transmission in a communication network. A wireless device may cancel a transmission (e.g., based on a pre-emption indication), determine a transmission power for a transmission (e.g., based on a power control message), and/or determine a retransmission of a message (e.g., based on a repetition indication).
1. A method comprising:
receiving, by a wireless device, configuration parameters indicating a redundancy version (RV) sequence associated with a configured grant for transmission of a transport block;
determining, based on the RV sequence and for each transmission occasion of consecutive transmission occasions, an RV for the transport block;
receiving downlink control information indicating that an uplink radio resource is pre-empted;
cancelling, based on the uplink radio resource overlapping with a first transmission occasion of the consecutive transmission occasions, a transmission of a first RV for the transport block scheduled for transmission via the first transmission occasion; and
transmitting, via a second transmission occasion of the consecutive transmission occasions and based on the uplink radio resource not overlapping with the second transmission occasion, a second RV for the transport block.
2. The method of claim 1 , wherein the configuration parameters further indicate the first transmission occasion and the second transmission occasion.
3. The method of claim 1 , wherein the first transmission occasion is associated with:
a starting symbol for transmission using the configured grant;
a transmission length indicating a quantity of symbols for transmission using the configured grant; and
a quantity of resource blocks for transmission using the configured grant.
4. The method of claim 3 , wherein the uplink radio resource overlapping with the first transmission occasion comprises one or more symbols of the uplink radio resource overlapping one or more symbols of the first transmission occasion.
5. The method of claim 3 , wherein the uplink radio resource overlapping with the first transmission occasion comprises one or more resource blocks of the uplink radio resource overlapping one or more resource blocks of the first transmission occasion.
6. The method of claim 1 , further comprising receiving one or more radio resource control messages comprising configuration parameters indicating associations between one or more pre-emption indicators and one or more uplink radio resources, wherein the one or more uplink radio resources comprise the uplink radio resource, and wherein based on the associations, each of the one or more pre-emption indicators, corresponding to one of the one or more uplink radio resources, indicates whether the one of the one or more uplink radio resources is pre-empted.
7. The method of claim 1 , wherein the first RV for the transport block is associated with a first RV value of the RV sequence and the second RV for the transport block is associated with a second RV value of the RV sequence.
8. 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 configuration parameters indicating a redundancy version (RV) sequence associated with a configured grant for transmission of a transport block;
determine, based on the RV sequence and for each transmission occasion of consecutive transmission occasions, an RV for the transport block;
receive downlink control information indicating that an uplink radio resource is pre-empted;
cancel, based on the uplink radio resource overlapping with a first transmission occasion of the consecutive transmission occasions, a transmission of a first RV for the transport block scheduled for transmission via the first transmission occasion; and
transmit, via a second transmission occasion of the consecutive transmission occasions and based on the uplink radio resource not overlapping with the second transmission occasion, a second RV for the transport block.
9. The wireless device of claim 8 , wherein the configuration parameters further indicate the first transmission occasion and the second transmission occasion.
10. The wireless device of claim 8 , wherein the first transmission occasion is associated with:
a starting symbol for transmission using the configured grant;
a transmission length indicating a quantity of symbols for transmission using the configured grant; and
a quantity of resource blocks for transmission using the configured grant.
11. The wireless device of claim 10 , wherein the uplink radio resource overlapping with the first transmission occasion comprises one or more symbols of the uplink radio resource overlapping one or more symbols of the first transmission occasion.
12. The wireless device of claim 10 , wherein the uplink radio resource overlapping with the first transmission occasion comprises one or more resource blocks of the uplink radio resource overlapping one or more resource blocks of the first transmission occasion.
13. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, cause the wireless device to:
receive one or more radio resource control messages comprising configuration parameters indicating associations between one or more pre-emption indicators and one or more uplink radio resources, wherein the one or more uplink radio resources comprise the uplink radio resource, and wherein based on the associations, each of the one or more pre-emption indicators, corresponding to one of the one or more uplink radio resources, indicates whether the one of the one or more uplink radio resources is pre-empted.
14. The wireless device of claim 8 , wherein the first RV for the transport block is associated with a first RV value of the RV sequence and the second RV for the transport block is associated with a second RV value of the RV sequence.
15. A non-transitory computer-readable medium storing instructions that, when executed, cause a wireless device to:
receive configuration parameters indicating a redundancy version (RV) sequence associated with a configured grant for transmission of a transport block;
determine, based on the RV sequence and for each transmission occasion of consecutive transmission occasions, an RV for the transport block;
receive downlink control information indicating that an uplink radio resource is pre-empted;
cancel, based on the uplink radio resource overlapping with a first transmission occasion of the consecutive transmission occasions, a transmission of a first RV for the transport block scheduled for transmission via the first transmission occasion; and
transmit, via a second transmission occasion of the consecutive transmission occasions and based on the uplink radio resource not overlapping with the second transmission occasion, a second RV for the transport block.
16. The non-transitory computer-readable medium of claim 15 , wherein the configuration parameters further indicate the first transmission occasion and the second transmission occasion.
17. The non-transitory computer-readable medium of claim 15 , wherein the first transmission occasion is associated with:
a starting symbol for transmission using the configured grant;
a transmission length indicating a quantity of symbols for transmission using the configured grant; and
a quantity of resource blocks for transmission using the configured grant.
18. The non-transitory computer-readable medium of claim 17 , wherein the uplink radio resource overlapping with the first transmission occasion comprises one or more symbols of the uplink radio resource overlapping one or more symbols of the first transmission occasion.
19. The non-transitory computer-readable medium of claim 17 , wherein the uplink radio resource overlapping with the first transmission occasion comprises one or more resource blocks of the uplink radio resource overlapping one or more resource blocks of the first transmission occasion.
20. The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed, cause the wireless device to:
receive one or more radio resource control messages comprising configuration parameters indicating associations between one or more pre-emption indicators and one or more uplink radio resources, wherein the one or more uplink radio resources comprise the uplink radio resource, and wherein based on the associations, each of the one or more pre-emption indicators, corresponding to one of the one or more uplink radio resources, indicates whether the one of the one or more uplink radio resources is pre-empted.
