Abstract
A network node configured to communicate with a wireless device (WD) utilizing at least one of a first Radio Access Technology (RAT) and a second RAT is provided. The network node includes processing circuitry configured to determine a rate matching configuration from a plurality of rate matching configurations for communication with the WD and cause the network node to transmit an indication of the determined rate matching configuration to the WD and to use the determined rate matching configuration in at least another transmission towards the WD.
Claims16
A network node configured to communicate with a wireless device (WD) utilizing at least one of a first Radio Access Technology (RAT) and a second RAT, the network node comprising processing circuitry configured to:
- determine a rate matching configuration from a plurality of rate matching configurations for communication with the WD;
- cause the network node to transmit an indication of the determined rate matching configuration to the WD and to use the determined rate matching configuration in at least one transmission towards the WD;
- and
- cause the network node to transmit a first message in a predetermined time slot, the first message indicating a value that causes the WD to at least one of:
- determine whether a set of resource elements are available for a Physical Downlink Shared Channel (PDSCH) in a set of time slots, the set of time slots including at least one slot of the set of time slots one of:
- in which the PDSCH is scheduled by a Physical Downlink Control Channel (PDCCH) Downlink Control Information (DCI) format;
- received after the PDCCH DCI format is detected;
- received after a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) is transmitted by the WD in response to the command detected in the PDCCH DCI format;
- and
- determined by the WD by a predetermined bitfield provided in the first message;
- and
- determine whether a second set of resource elements indicated by a first rate matching configuration and indicated by a second rate matching configuration of the plurality of rate matching configurations are available for the PDSCH in the set of time slots, the set of time slots being indicated at least by one of the first message and a second message different from the first message.
A method implemented in a network node configured to communicate with a wireless device (WD) utilizing at least one of a first Radio Access Technology (RAT) and a second RAT, the method comprising:
- determining a rate matching configuration from a plurality of rate matching configurations for communication with the WD;
- transmitting an indication of the determined rate matching configuration to the WD and using the determined rate matching configuration in at least one transmission towards the WD;
- and
- transmitting a first message in a predetermined time slot, the first message indicating a value that causes the WD to at least one of:
- determine whether a set of resource elements are available for a Physical Downlink Shared Channel (PDSCH) in a set of time slots, the set of time slots including at least one slot of the set of time slots one of:
- in which the PDSCH is scheduled by a Physical Downlink Control Channel (PDCCH) Downlink Control Information (DCI) format;
- received after the PDCCH DCI format is detected;
- received after a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) is transmitted by the WD in response to the command detected in the PDCCH DCI format;
- and
- determined by the WD by a predetermined bitfield provided in the first message;
- and
- determine whether a second set of resource elements indicated by a first rate matching configuration and indicated by a second rate matching configuration of the plurality of rate matching configurations are available for the PDSCH in the set of time slots, the set of time slots being indicated at least by one of the first message and a second message different from the first message.
