Abstract

Claims (71)

1 . A method comprising:

receiving, by a wireless device, downlink control information (DCI) that:

comprises information indicating a plurality of resource assignments associated with a plurality of different time durations for uplink transmission; and

is scrambled with a radio network temporary identifier (RNTI); and

transmitting one or more transport blocks (TBs) via the resource assignments and using a transmission mode that is selected based on a type of the RNTI, wherein for the selection of the transmission mode:

a first type of RNTI is associated with a TB repetition transmission mode in which at least one repetition of a TB is transmitted; and

a second type of RNTI is associated with a multi-TB transmission mode in which different TBs are transmitted

wherein the transmitting comprises transmitting:

a TB and one or more corresponding repetitions of the TB; or

a plurality of different TBs.

2 . The method of claim 1 , further comprising:

descrambling the DCI using the RNTI; and

determining, based on the type of the RNTI, that consecutive physical uplink shared channel (PUSCH) opportunities are configured for the TB repetition transmission mode.

3 . The method of claim 1 , further comprising:

determining, based on a second field in the DCI, that consecutive physical uplink shared channel (PUSCH) opportunities are configured for the multi-TB transmission mode.

4 . The method of claim 1 , wherein the resource assignments are associated with an ultra reliable low-latency communications (URLLC) service.

5 . The method of claim 1 , wherein the DCI comprises first DCI, and wherein the method further comprises:

receiving second DCI comprising field, wherein the field of the second DCI indicates that second resource assignments are configured for the multi-TB transmission mode, and wherein the second DCI and the first DCI comprise a same size.

6 . The method of claim 1 , wherein the DCI comprises at least one of:

a frequency domain resource assignment indicating one or more resource blocks;

a time domain resource assignment indicating a plurality of transmission time intervals (TTIs);

a transmit power control command for uplink transmission;

a modulation and coding scheme for uplink transmission; or

a hybrid automatic repeat request (HARQ) process number.

7 . The method of claim 1 , wherein the DCI comprises at least one of:

a time domain resource assignment field;

a modulation and coding field;

a new data indicator field; or

a redundancy version field.

8 . The method of claim 1 , wherein:

an RNTI of type cell RNTI (C-RNTI) is associated with the TB repetition transmission mode; and

an RNTI of type configured scheduling RNTI (CS-RNTI) is associated the multi-TB transmission mode.

9 . A method comprising:

receiving, by a wireless device, downlink control information (DCI) scrambled by a radio network temporary identifier (RNTI), wherein the DCI indicates a plurality of resource assignments for a plurality of different physical uplink shared channel (PUSCH) opportunities;

selecting, based on a type of the RNTI, between:

using the PUSCH opportunities for transmission of a single transport block (TB) repetition; or

using the PUSCH opportunities for transmission of different TBS; and

transmitting, via the PUSCH opportunities and based on the selecting:

a first TB and one or more repetitions of the first TB; or

a plurality of different TBs.

10 . The method of claim 9 , further comprising:

selecting, based on the type of the RNTI, to use the PUSCH opportunities for uplink transmission of thea single TB repetition, wherein the transmitting comprises transmitting the TB and the one or more repetitions of the TB in consecutive time durations.

11 . The method of claim 9 , further comprising:

selecting, based on the type of the RNTI, to use the PUSCH opportunities for uplink transmission of different TBs, wherein the transmitting comprises:

transmitting the first TB during a first time duration; and

transmitting at least one second TB during at least one second time duration, wherein the first time duration and the at least one second time duration are consecutive time durations.

12 . The method of claim 9 ,

wherein using the PUSCH opportunities for transmission of the single TB repetition is associated with an ultra reliable low-latency communications (URLLC) service, and

wherein using the PUSCH opportunities for transmission of different TBs is associated with an enhanced mobile broadband (eMBB) service.

13 . The method of claim 9 :

wherein the selecting comprises associating a cell RNTI (C-RNTI) with using the PUSCH opportunities for TB repetitions, and associating configured scheduling RNTI (CS-RNTI) with using the PUSCH opportunities for non-repetition TB transmissions.

14 . A method comprising:

receiving, by a wireless device, downlink control information (DCI) comprising an indication of a plurality of resource assignments for uplink transmission;

determining, based on a field ina type of radio network temporary identifier (RNTI) used with the DCI, whether the resource assignments are to be used for transmitting TB repetitions, or for transmitting different TBs:

a first type of RNTI is associated with a first scheduling mode for transmitting TB repetitions, and

a second type of RNTI is associated with a second scheduling mode for transmitting different TBS; and

transmitting via the plurality of resource assignments:

a TB and one or more repetitions of the TB, based on the first scheduling mode; or

a plurality of different TBs, based on the second scheduling mode.

15 . The method of claim 14 , further comprising:

determining that the plurality of resource assignments are for transmitting TB repetitions, wherein the transmitting comprises transmitting the TB and the one or more repetitions of the TB in the consecutive time durations.

16 . The method of claim 14 , further comprising:

determining that the plurality of resource assignments are for transmitting different TBs, wherein the transmitting comprises:

transmitting a first TB during a first time duration; and

transmitting at least one second TB during at least one second time duration, wherein the first time duration and the at least one second time duration are consecutive time durations.

17 . The method of claim 14 ,

wherein the first scheduling mode is associated with an ultra reliable low-latency communications (URLLC) service, and

wherein the second scheduling mode is associated with an enhanced mobile broadband (eMBB) service.

18 . The method of claim 14 , wherein:

an RNTI of type cell RNTI (C-RNTI) is associated with the first scheduling mode for transmitting TB repetitions; and

an RNTI of type configured scheduling RNTI (CS-RNTI) is associated the second scheduling mode for transmitting different TBS.
