Abstract

The present disclosure provides a method in a terminal device. The method includes: receiving, from a network node, at least one of cell specific Time Division Duplex, TDD, uplink-downlink configuration information and User Equipment, UE, specific TDD uplink-downlink configuration information; and determining whether a slot is available for Physical Uplink Shared Channel, PUSCH, repetition based on the at least one of the cell specific TDD uplink-downlink configuration information and the UE specific TDD uplink-downlink configuration information.

First claim

1 . A method performed by a terminal device, comprising:
determining a slot to be an available slot for a physical uplink shared channel, PUSCH, repetition based at least in part on an amount X of symbols available for PUSCH transmission being equal to L scheduled symbols for the PUSCH transmission in the slot; and performing PUSCH repetitions through K determined available slots, wherein K is an amount of the PUSCH repetitions.

2 . (canceled)

3 . The method according to claim 1 , wherein redundancy version, RV, cycling is counted based on the determined available slots for the PUSCH transmission.

4 . The method according to claim 1 , further comprising:
transmitting to a network node a report on whether the terminal device is capable of supporting an extended number of PUSCH repetitions, wherein the extended number of PUSCH repetitions is greater than a number of PUSCH repetitions supported by a terminal device that is not capable of supporting the extended number of PUSCH repetitions.

5 . The method according to claim 1 , wherein a value of K depends on a first type of the PUSCH repetition.

6 . The method according to claim 5 , further comprising:
receiving configuration information about one or more PUSCH repetition types from a network node, wherein the one or more PUSCH repetition types include the first type of the PUSCH repetition, and each of the one or more PUSCH repetition types supports at least one candidate value of K.

7 .- 9 . (canceled)

10 . The method according to claim 5 , wherein the first type of the PUSCH repetition supports an extended number of PUSCH repetitions.

11 .- 12 . (canceled)

13 . The method according to claim 4 , wherein the report comprises a report on one or more PUSCH repetition types supported by the terminal device.

14 . (canceled)

15 . The method according to claim 13 , wherein the terminal device is configured with one of the one or more PUSCH repetition types.

16 .- 18 . (canceled)

19 . A method performed by a network node, comprising:
determining a slot to be an available slot for a physical uplink shared channel, PUSCH, repetition based at least in part on an amount X of symbols available for PUSCH transmission being equal to L scheduled symbols for the PUSCH transmission in the slot; and receiving PUSCH repetitions through equal to or less than K determined available slots, wherein K is a number of the PUSCH repetitions.

20 . (canceled)

21 . The method according to claim 19 , wherein redundancy version, RV, cycling is counted based on the determined available slots for the PUSCH transmission.

22 . The method according to claim 19 , further comprising:
receiving a report on whether the terminal device is capable of supporting extended number of PUSCH repetitions, wherein the extended number of PUSCH repetitions is greater than a number of PUSCH repetitions supported by a terminal device that is not capable of supporting the extended number of PUSCH repetitions.

23 . The method according to claim 19 , wherein a value of K depends on a first type of the PUSCH repetition.

24 . The method according to claim 23 , further comprising:
sending to the terminal device configuration information about one or more PUSCH repetition types, wherein the one or more PUSCH repetition types include the first type of the PUSCH repetition, and each of the one or more PUSCH repetition types supports at least one candidate value of K.

25 .- 27 . (canceled)

28 . The method according to claim 23 , wherein the first type of the PUSCH repetition supports an extended number of PUSCH repetitions.

29 .- 59 . (canceled)

60 . A terminal device, comprising a processor and a memory, the memory comprising instructions executable by the processor whereby the terminal device is operative to:
determine a slot to be an available slot for a physical uplink shared channel, PUSCH, repetition based at least in part on an amount X of symbols available for PUSCH transmission being equal to L scheduled symbols for the PUSCH transmission in the slot; and perform PUSCH repetitions through K determined available slots, wherein K is an amount of the PUSCH repetitions.

61 . (canceled)

62 . A network node, comprising a processor and a memory, the memory comprising instructions executable by the processor whereby the network node is operative to:
determine a slot to be an available slot for a physical uplink shared channel, PUSCH, repetition based at least in part on an amount X of symbols available for PUSCH transmission being equal to L scheduled symbols for the PUSCH transmission in the slot; and receive PUSCH repetitions through equal to or less than K determined available slots, wherein K is a number of the PUSCH repetitions.
