Abstract

A user equipment (UE) that communicates via mini-slot-based repetitions includes receiving circuitry configured to receive a radio resource control (RRC) message comprising first information for configuring a first number of repetitions for physical uplink shared channel (PUSCH) transmissions, second information for configuring a second number of repetitions for PUSCH transmissions, and third information for indicating a repetition type from a set of repetition types comprising a first repetition type and a second repetition type, the first repetition type indicating only one repetition to be transmitted within a slot, the second repetition type indicating repetitions to be transmitted within the slot. The UE includes transmitting circuitry configured to perform, based on the third information, the first number of repetitions or the second number of repetitions, wherein the transmitting circuitry performs the second number of repetitions in a case that the third information indicates the second repetition type.

First claim

The invention claimed is:

1. A user equipment (UE) that communicates via mini-slot-based repetitions, the UE comprising:
at least one processor; and
at least one memory coupled to the at least one processor, the at least one memory storing one or more computer-executable instructions that, when executed by the at least one processor, cause the UE to:
receive a radio resource control (RRC) message, the RRC message comprising:
first information used for configuring a first number of repetitions for physical uplink shared channel (PUSCH) transmissions,
second information used for configuring a second number of repetitions for the PUSCH transmissions, and
third information used for indicating a repetition type from a set of repetition types, the set of the repetition types comprising a first repetition type and a second repetition type, the first repetition type indicating only one repetition for the PUSCH transmissions within a slot, the second repetition type indicating more than one repetitions for the PUSCH transmissions within the slot; and

perform, based on the third information, either the first number of repetitions for the PUSCH transmissions or the second number of repetitions for the PUSCH transmissions, wherein
the second number of repetitions for the PUSCH transmissions is performed when the third information indicates the second repetition type.

2. The UE of claim 1 , wherein a starting symbol and a length of a PUSCH transmission for the second repetition type are configured by the RRC message.

3. The UE of claim 1 , wherein in a case that a number of available symbols used for a repetition for the second repetition type within the slot is smaller than a specific value, the repetition is omitted.

4. The UE of claim 1 , wherein a length of each repetition for the second repetition type is varied based on a number of available symbols within the slot.

5. A base station (BS) that communicates via mini-slot-based repetitions, the BS comprising:
at least one processor; and
at least one memory coupled to the at least one processor, the at least one memory storing one or more computer-executable instructions that, when executed by the at least one processor, cause the BS to:
transmit a radio resource control (RRC) message, the RRC message comprising:
first information used for configuring a first number of repetitions for physical uplink shared channel (PUSCH) transmissions,
second information used for configuring a second number of repetitions for the PUSCH transmissions, and
third information used for indicating a repetition type from a set of repetition types, the set of the repetition types comprising a first repetition type and a second repetition type, the first repetition type indicating only one repetition for the PUSCH transmissions within a slot, the second repetition type indicating more than one repetitions for the PUSCH transmissions within the slot, wherein:

the UE performs, based on the third information, either the first number of repetitions for the PUSCH transmissions or the second number of repetitions for the PUSCH transmissions, and
the second number of repetitions for the PUSCH transmissions is performed by the UE when the third information indicates the second repetition type.

6. The BS of claim 5 , wherein a starting symbol and a length of a PUSCH transmission for the second repetition type are configured by the RRC message.

7. The BS of claim 5 , wherein in a case that a number of available symbols used for a repetition for the second repetition type within the slot is smaller than a specific value, the repetition is omitted.

8. The BS of claim 5 , wherein a length of each repetition for the second repetition type is varied based on a number of available symbols within the slot.

9. A communication method performed by a user equipment (UE) that communicates via mini-slot-based repetitions, the communication method comprising:
receiving a radio resource control (RRC) message, the RRC message comprising:
first information used for configuring a first number of repetitions for physical uplink shared channel (PUSCH) transmissions,
second information used for configuring a second number of repetitions for the PUSCH transmissions, and
third information used for indicating a repetition type from a set of repetition types, the set of the repetition types comprising a first repetition type and a second repetition type, the first repetition type indicating only one repetition for the PUSCH transmissions within a slot, the second repetition type indicating more than one repetitions for the PUSCH transmissions within the slot; and

performing, based on the third information, either the first number of repetitions for the PUSCH transmissions or the second number of repetitions for the PUSCH transmissions, wherein
the second number of repetitions for the PUSCH transmissions is performed by the UE when the third information indicates the second repetition type.

10. The communication method of claim 9 , wherein a starting symbol and a length of a PUSCH transmission for the second repetition type are configured by the RRC message.

11. The communication method of claim 9 , wherein in a case that a number of available symbols used for a repetition for the second repetition type within the slot is smaller than a specific value, the repetition is omitted.

12. The communication method of claim 9 , wherein a length of each repetition for the second repetition type is varied based on a number of available symbols within the slot.
