Abstract

According to certain embodiments, a user equipment, UE, is operable for multiple sub-carrier spacing values. The UE comprises memory operable to store instructions and processing circuitry operable to execute the instructions, whereby the UE is operable to determine one of a plurality of time-domain resource allocation tables based on first information received from a network node. The first information comprises a Radio Network Temporary Identifier, RNTI. The UE is operable to determine a time-domain resource allocated to the UE for transmission or reception of a wireless signal based on the determined one of the plurality of time-domain resource allocation tables and second information received from the network node. The second information comprises a time-domain resource allocation field value received in downlink control information, DCI. The UE is further operable to transmit or receive the wireless signal using the determined time-domain resource.

Claims (38)

1. A user equipment, UE, operable for multiple sub-carrier spacing values, the UE comprising memory operable to store instructions and processing circuitry operable to execute the instructions, whereby the UE is operable to:

determine one of a plurality of time-domain resource allocation tables based on first information received from a network node, the first information comprising a Radio Network Temporary Identifier, RNTI, wherein each time-domain resource allocation table comprises a plurality of entries, each entry corresponding to a respective time-domain resource allocation, and wherein the time-domain resource allocation tables comprise different combinations of starting orthogonal frequency division multiplexing, OFDM, symbol position and duration in OFDM symbols for the time-domain resource allocation;

determine a time-domain resource allocated to the UE for transmission or reception of a wireless signal based on the determined one of the plurality of time-domain resource allocation tables and second information received from the network node, the second information comprising a time-domain resource allocation field value received in downlink control information, DCI, the second information indicating which of the plurality of entries of the determined one of the plurality of time-domain resource allocation tables to use to determine the time-domain resource allocated to the UE; and

transmit or receive the wireless signal using the determined time-domain resource.

2. The UE of claim 1 , wherein the plurality of time-domain resource allocation tables relates to time-domain resource allocation for physical uplink shared channel, PUSCH, or for physical downlink shared channel, PDSCH.

3. The UE of claim 1 , wherein the plurality of time-domain resource allocation tables comprises at least one of pre-defined tables with default values for the time domain resource allocation and radio resource control, RRC, configured tables.

4. The UE of claim 1 , wherein the first information comprises information indicating a search space related to a control channel used to schedule the wireless signal.

5. The UE of claim 1 , wherein the first information comprises information related to a control channel resource set, CORESET, used to schedule the wireless signal.

6. The UE of claim 1 , wherein the first information comprises information related to bandwidth part.

7. The UE of claim 1 , wherein the first information comprises information that indicates a slot format.

8. The UE of claim 1 , wherein the first information comprises a cyclic prefix, an orthogonal frequency division multiplexing, OFDM, subcarrier spacing, or other information indicating numerology.

9. A method performed by a user equipment, UE, operable for multiple sub-carrier spacing values, the method comprising:

determining one of a plurality of time-domain resource allocation tables based on first information received from a network node, the first information comprising a Radio Network Temporary Identifier, RNTI, wherein each time-domain resource allocation table comprises a plurality of entries, each entry corresponding to a respective time-domain resource allocation, and wherein the time-domain resource allocation tables comprise different combinations of starting orthogonal frequency division multiplexing, OFDM, symbol position and duration in OFDM symbols for the time-domain resource allocation;

determining a time-domain resource allocated to the UE for transmission or reception of a wireless signal based on the determined one of the plurality of time-domain resource allocation tables and second information received from the network node, the second information comprising a time-domain resource allocation field value received in downlink control information, DCI, the second information indicating which of the plurality of entries of the determined one of the plurality of time-domain resource allocation tables to use to determine the time-domain resource allocated to the UE; and

transmitting or receiving the wireless signal using the determined time-domain resource.

10. A network node operable for multiple sub-carrier spacing values, the network node comprising memory operable to store instructions and processing circuitry operable to execute the instructions, whereby the network node is operable to:

determine a time-domain resource to allocate to a user equipment, UE, for transmission or reception of a wireless signal;

send the UE first information from which the UE determines one of a plurality of time-domain resource allocation tables and second information from which the UE determines the time-domain resource based on the determined one of the plurality of time-domain resource allocation tables, the first information comprising a Radio Network Temporary Identifier, RNTI, and the second information comprising a time-domain resource allocation field value sent in downlink control information, DCI; and

transmit or receive the wireless signal using the allocated time-domain resource;

wherein:

each time-domain resource allocation table comprises a plurality of entries, each entry corresponding to a respective time-domain resource allocation;

the time-domain resource allocation tables comprise different combinations of starting orthogonal frequency division multiplexing, OFDM, symbol position and duration in OFDM symbols for the time-domain resource allocation; and

the second information indicates which of the plurality of entries of the determined one of the plurality of time-domain resource allocation tables the UE should use to determine the time-domain resource allocated to the UE.

11. The network node of claim 10 , wherein the plurality of time-domain resource allocation tables relates to time-domain resource allocation for physical uplink shared channel, PUSCH, or for physical downlink shared channel, PDSCH.

12. The network node of claim 10 , wherein the plurality of time-domain resource allocation tables comprises at least one of pre-defined tables with default values for the time domain resource allocation and radio resource control, RRC, configured tables.

13. The network node of claim 10 , wherein the first information comprises information indicating a search space related to a control channel used to schedule the wireless signal.

14. The network node of claim 10 , wherein the first information comprises information related to a control channel resource set, CORESET, used to schedule the wireless signal.

15. The network node of claim 10 , wherein the first information comprises information related to bandwidth part.

16. The network node of claim 10 , wherein the first information comprises information that indicates a slot format.

17. The network node of claim 10 , wherein the first information comprises a cyclic prefix, an orthogonal frequency division multiplexing, OFDM, subcarrier spacing, or other information indicating numerology.

18. A method performed by a network node operable for multiple sub-carrier spacing values, the method comprising:

determining a time-domain resource to allocate to a user equipment, UE, for transmission or reception of a wireless signal;

sending the UE first information from which the UE determines one of a plurality of time-domain resource allocation tables and second information from which the UE determines the time-domain resource based on the determined one of the plurality of time-domain resource allocation tables, the first information comprising a Radio Network Temporary Identifier, RNTI, and the second information comprising a time-domain resource allocation field value sent in downlink control information, DCI; and
