Method for transmitting PUSCH and user equipment
A method for transmitting physical uplink shared channel (PUSCH) and a user equipment (UE) are provided. In the method, a configuration of a first PUSCH with a number of PUSCH repetitions is received. Physical Downlink Control Channel (PDCCH) which includes a Transmit Power Control (TPC) command is received. Whether the PDCCH is received within a number of symbols before a first symbol of a slot bundle is determined. In response to determining the PDCCH is received within the number of symbols before the first symbol of the slot bundle, the TPC command is applied for a first PUSCH transmission occasion within the slot bundle. In response to determining the PDCCH is not received within the number of symbols before the first symbol of the slot bundle, the TPC command is applied for a second PUSCH transmission occasion within a second slot bundle after the slot bundle.
1. A method for transmitting Physical Uplink Shared Channel (PUSCH), adapted for a user equipment (UE), the method comprising:
receiving a configuration of a first PUSCH with a number of PUSCH repetitions;
receiving Physical Downlink Control Channel (PDCCH) which comprises a Transmit Power Control (TPC) command;
determining whether the PDCCH is received within a number of symbols before a first symbol of a slot bundle, wherein the first symbol is an initial symbol in the slot bundle, and the slot bundle comprises a plurality of time slots used for transmitting the first PUSCH with the number of the PUSCH repetitions;
in response to determining the PDCCH is received within the number of symbols before the first symbol of the slot bundle, applying the TPC command for a first PUSCH transmission occasion; and
in response to determining the PDCCH is not received within the number of symbols before the first symbol of the slot bundle, applying the TPC command for a second PUSCH transmission occasion, wherein
the first PUSCH transmission occasion is within the slot bundle, and
the second PUSCH transmission occasion is within a second slot bundle after the slot bundle.
2. The method of claim 1 , further comprising:
receiving a configuration of a first length of the slot bundle, wherein the first length is a number of time slots in the slot bundle, and a value of the first length is N; and
initiating the slot bundle at a first slot in which the first PUSCH with the number of PUSCH repetitions initiates, wherein
the slot bundle ends at a second slot which is a N-th slot counted from the first slot.
3. The method of claim 2 , further comprising:
receiving a configuration of a second length of the second slot bundle, wherein the second length is a number of time slots in the second slot bundle, and a value of the second length is N; and
initiating the second slot bundle at a third slot which is a next slot of the second slot in response to the number of PUSCH repetitions of the first PUSCH being larger than N, wherein
the second PUSCH transmission occasion is used for transmitting the first PUSCH.
4. The method of claim 2 , further comprising:
receiving a configuration of a second length of the second slot bundle, wherein the second length is a number of time slots in the second slot bundle, and a value of the second length is N; and
initiating the second slot bundle at a fourth slot in which a second PUSCH initiates in response to the number of PUSCH repetitions of the first PUSCH not larger than N, wherein
the second PUSCH transmission occasion is used for transmitting the second PUSCH.
5. The method of claim 1 , wherein the configuration of a first PUSCH with the number of PUSCH repetitions is received in a Radio Resource Control (RRC) message.
6. The method of claim 1 , wherein the configuration of the first length of the slot bundle is received in an RRC message.
7. A user equipment (UE), comprising:
a transceiver, used for transmitting or receiving signals;
a memory, used for storing a program code; and
a processor, coupled to the transceiver and the memory, and configured to load and execute the program code to perform:
receiving, through the transceiver, a configuration of a first Physical Uplink Shared Channel (PUSCH) with a number of PUSCH repetitions;
receiving, through the transceiver, Physical Downlink Control Channel (PDCCH) which comprises a Transmit Power Control (TPC) command;
determining whether the PDCCH is received within a number of symbols before a first symbol of a slot bundle, wherein the first symbol is an initial symbol in the slot bundle, and the slot bundle comprises a plurality of time slots used for transmitting the first PUSCH with the number of the PUSCH repetitions;
in response to determining the PDCCH is received within the number of symbols before the first symbol of the slot bundle, applying the TPC command for a first PUSCH transmission occasion; and
in response to determining the PDCCH is not received within the number of symbols before the first symbol of the slot bundle, applying the TPC for a second PUSCH transmission occasion, wherein
the first PUSCH transmission occasion is within the slot bundle, and
the second PUSCH transmission occasion is within a second slot bundle after the slot bundle.
8. The UE of claim 7 , wherein the processor is further configured for:
receiving, through the transceiver, a configuration of a first length of the slot bundle, wherein the first length is a number of time slots in the slot bundle, and a value of the first length is N; and
initiating the slot bundle at a first slot in which the first PUSCH with the number of PUSCH repetitions initiates, wherein
the slot bundle ends at a second slot which is a N-th slot counted from the first slot.
9. The UE of claim 8 , wherein the processor is further configured for:
receiving, through the transceiver, a configuration of a second length of the second slot bundle, wherein the second length is a number of time slots in the second slot bundle, and a value of the second length is N; and
initiating the second slot bundle at a third slot which is a next slot of the second slot in response to the number of PUSCH repetitions of the first PUSCH being larger than N, wherein
the second PUSCH transmission occasion is used for transmitting the first PUSCH.
10. The UE of claim 8 , wherein the processor is further configured for:
receiving, through the transceiver, a configuration of a second length of the second slot bundle, wherein the second length is a number of time slots in the second slot bundle, and a value of the second length is N; and
initiating the second slot bundle at a fourth slot in which a second PUSCH initiates in response to the number of PUSCH repetitions of the first PUSCH not larger than N, wherein
the second PUSCH transmission occasion is used for transmitting the second PUSCH.
11. The UE of claim 7 , wherein the configuration of a first PUSCH with the number of PUSCH repetitions is received in a Radio Resource Control (RRC) message.
12. The UE of claim 8 , wherein the configuration of the first length of the slot bundle is received in an RRC message.
