Abstract

A wireless device may receive configuration parameters indicating a ratio threshold for selecting between rate matching and puncturing. The wireless device may receive a first downlink control information (DCI) scheduling an uplink transport block (TB) via uplink resources of the cell, and a second DCI indicating a transmission cancelation on one or more resources of the uplink resources. The wireless device may map the uplink TB to a portion of the uplink resources based on the rate matching in response to a ratio of the one or more resources to the uplink resources being equal to or greater than the ratio threshold, and the puncturing in response to the ratio being less than the ratio threshold. The wireless device may transmit the uplink TB via the portion of the uplink resources in response to the mapping.

Claims (49)

1. A method comprising:

receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters of a cell, wherein the configuration parameters indicate a ratio threshold for selecting between rate matching and puncturing;

receiving a first downlink control information (DCI) scheduling an uplink transport block (TB) via uplink resources of the cell;

receiving a second DCI indicating a transmission cancelation on one or more resources of the uplink resources;

selecting between the rate matching and the puncturing to map the uplink TB to a portion of the uplink resources based on a ratio of the one or more resources to the uplink resources, wherein the portion of the uplink resources does not conflict with the one or more resources;

mapping the uplink TB to the portion of the uplink resources based on:

the rate matching in response to the ratio being equal to or greater than the ratio threshold; and

the puncturing in response to the ratio being less than the ratio threshold; and

transmitting the uplink TB via the portion of the uplink resources in response to the mapping.

2. The method of claim 1 , wherein the selecting is further based on a time offset value.

3. The method of claim 2 , further comprising selecting the rate matching to map the uplink TB to the portion of the uplink resources based on the time offset value being equal to or greater than a first time value.

4. The method of claim 2 , further comprising selecting the puncturing to map the uplink TB to the portion of the uplink resources based on the time offset value being less than a first time value.

5. The method of claim 1 , wherein the selecting is further based on an information type of the uplink resources.

6. The method of claim 5 , wherein the selecting comprises selecting the rate matching to map the uplink TB to the portion of the uplink resources in response to the uplink resources being with uplink control information.

7. The method of claim 5 , wherein the selecting comprises selecting the puncturing to map the uplink TB to the portion of the uplink resources in response to the uplink resources being without uplink control information.

8. The method of claim 1 , wherein the selecting is further based on a redundancy version of the one or more resources of the uplink resources.

9. The method of claim 8 , wherein the selecting comprises selecting the rate matching to map the uplink TB to the portion of the uplink resources in response to the redundancy version of the one or more resources of the uplink resources being with systematic bits.

10. The method of claim 8 , wherein the selecting comprises selecting the puncturing to map the uplink TB to the portion of the uplink resources in response to the redundancy version of the one or more resources of the uplink resources being without systematic bits.

11. A wireless device comprising:

18. The wireless device of claim 11 , wherein the instructions further cause the wireless device to select between the rate matching and the puncturing further based on a redundancy version of the one or more resources of the uplink resources.

19. The wireless device of claim 18 , wherein the instructions further cause the wireless device to select the rate matching to map the uplink TB to the portion of the uplink resources in response to the redundancy version of the one or more resources of the uplink resources being with systematic bits.

20. A system comprising:

a base station comprising one or more first processors and first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:

transmit one or more radio resource control (RRC) messages comprising configuration parameters of a cell, wherein the configuration parameters indicate a ratio threshold for selecting between rate matching and puncturing;

transmit a first downlink control information (DCI) scheduling an uplink transport block (TB) via uplink resources of the cell; and

transmit a second DCI indicating a transmission cancelation on one or more resources of the uplink resources; and

a wireless device comprising one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:

receive the one or more RRC, the first DCI, and the second DCI;

select between the rate matching and the puncturing to map the uplink TB to a portion of the uplink resources based on a ratio of the one or more resources to the uplink resources, wherein the portion of the uplink resources does not conflict with the one or more resources;
