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 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 a radio resource control (RRC) message comprising configuration parameters indicating:
a number of repetitions of a transport block (TB) associated with a configured grant for transmissions of the TB via a number of consecutive slots comprising a first slot and a second slot; and
a redundancy version (RV) sequence for the number of repetitions of the TB;
determine, based on the RV sequence:
a first RV value associated with a first transmission of the TB in the first slot; and
a second RV value associated with a second transmission of the TB in the second slot;
receive a downlink control information (DCI) comprising a cancelation indication indicating that an uplink radio resource is pre-empted;
in response to receiving the DCI and the uplink radio resource overlapping with the first slot, drop the first transmission of the TB with the first RV value; and
transmit the TB with the second RV value, wherein the uplink radio resource does not overlap with the second slot.
2 . The wireless device of claim 1 , wherein the configuration parameters indicate, for each slot of the number of consecutive slots of the configured grant:
a starting symbol for each transmission using the configured grant;
a transmission length indicating a quantity of symbols for each transmission using the configured grant; and
one or more resource blocks for each transmission using the configured grant.
3 . The wireless device of claim 2 , wherein the RV sequence comprises a plurality of RV values comprising the first RV value and the second RV value, wherein the first RV value is different from the second RV value.
4 . The wireless device of claim 3 , wherein the uplink radio resource comprises at least one or more resource blocks in the first slot, wherein the one or more resource blocks of the uplink radio resource overlap the one or more resource blocks of the configured grant in the first slot.
5 . The wireless device of claim 4 , wherein the uplink radio resource comprises at least one or more resource blocks in the second slot, wherein the at least one or more resource blocks do not overlap the one or more resource blocks of the configured grant in the second slot.
6 . The wireless device of claim 4 , wherein the DCI is a group common DCI addressed by a group radio network temporary identifier (RNTI) for the cancelation indication.
7 . The wireless device of claim 6 , wherein the uplink radio resource comprises at least one or more resource blocks in the first slot, wherein the one or more resource blocks of the uplink radio resource overlap the one or more resource blocks of the configured grant in the first slot.
8 . The wireless device of claim 7 , wherein the uplink radio resource comprises at least one or more resource blocks in the second slot, wherein the at least one or more resource blocks do not overlap the one or more resource blocks of the configured grant in the second slot.
9 . The wireless device of claim 4 , wherein the instructions further cause the wireless device to repeat the TB across the number of consecutive slots applying the same symbol allocation in each slot.
10 . The wireless device of claim 9 , wherein the instructions further cause the wireless device to omit the transmission on the slot in response to the wireless device determining symbols of a slot allocated for PUSCH as downlink symbols.
11 . 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 a radio resource control (RRC) message comprising configuration parameters indicating:
a number of repetitions of a transport block (TB) associated with a configured grant for transmissions of the TB via a number of consecutive slots comprising a first slot and a second slot; and
a redundancy version (RV) sequence for the number of repetitions of the TB;
determine, based on the RV sequence:
a first RV value associated with a first transmission of the TB in the first slot; and
a second RV value associated with a second transmission of the TB in the second slot;
receive a downlink control information (DCI) comprising a cancelation indication;
drop, based on the cancelation indication and in the first slot, the first transmission of the TB with the first RV value; and
transmit, in the second slot, the TB with the second RV value.
12 . The wireless device of claim 11 , wherein the configuration parameters indicate, for each slot of the number of consecutive slots of the configured grant:
a starting symbol for each transmission using the configured grant;
a transmission length indicating a quantity of symbols for each transmission using the configured grant; and
one or more resource blocks for each transmission using the configured grant.
13 . The wireless device of claim 12 , wherein the RV sequence comprises a plurality of RV values comprising the first RV value and the second RV value, wherein the first RV value is different from the second RV value.
14 . The wireless device of claim 13 , wherein the cancelation indication indicates that uplink radio resource is pre-empted in the first slot.
15 . The wireless device of claim 14 , wherein the uplink radio resource comprises at least one or more resource blocks in the first slot, wherein the one or more resource blocks of the uplink radio resource overlap the one or more resource blocks of the configured grant in the first slot.
16 . The wireless device of claim 15 , wherein the uplink radio resource comprises at least one or more resource blocks in the second slot, wherein the at least one or more resource blocks do not overlap the one or more resource blocks of the configured grant in the second slot.
17 . The wireless device of claim 15 , wherein the DCI is a group common DCI addressed by a group radio network temporary identifier (RNTI) for the cancelation indication.
18 . The wireless device of claim 17 , wherein the configured grant, based on being a type 2 configured grant, is activated by a second DCI, wherein the second DCI is different from the DCI comprising the cancelation indication.
19 . The wireless device of claim 17 , wherein the uplink radio resource comprises at least one or more resource blocks in the first slot, wherein the one or more resource blocks of the uplink radio resource overlap the one or more resource blocks of the configured grant in the first slot.
20 . The wireless device of claim 19 , wherein the uplink radio resource comprises at least one or more resource blocks in the second slot, wherein the at least one or more resource blocks do not overlap the one or more resource blocks of the configured grant in the second slot.
