A wireless device receives a radio network temporary identifier (RNTI) for multicast and broadcast services (MBS) of a cell, a first parameter indicating a first location of first common frequency resources (CFR) for the MBS within a first BWP and a second parameter indicating a second location of second CFR for the MBS within a second BWP. The wireless device receives, based on the RNTI, via an active BWP of the cell a group common downlink control information (DCI) scheduling a transport block of the MBS, wherein: the group common DCI is received via the first CFR for the MBS based on the first BWP being the active BWP or the group common DCI is received via the second CFR for the MBS based on the second BWP being the active BWP; and the transport block of the MBS.

No: 18/244451 Application Filed: September 11, 2023 Assignees: Ofinno, LLC (Reston, VA, US) Claim: 1. A method comprising: receiving, by a wireless device, one or more radio resource control (RRC) messages comprising: a radio network temporary identifier (RNTI) for multicast and broadcast services (MBS) of a cell; and configuration parameters of a first bandwidth part (BWP) and a second BWP of the cell, the configuration parameters comprising: a first parameter indicating a first location of first common frequency resources (CFR) for the MBS within the first BWP; and a second parameter indicating a second location of second CFR for the MBS within the second BWP; and receiving, based on the RNTI, via an active BWP of the cell: a group common downlink control information (DCI) scheduling a transport block of the MBS, wherein: the group common DCI is received via the first CFR for the MBS based on the first BWP being the active BWP; or the group common DCI is received via the second CFR for the MBS based on the second BWP being the active BWP; and the transport block of the MBS. Claim: 2. The method of claim 1, wherein the configuration parameters indicate a first starting resource block (RB) of first RBs of the first CFR and a number of the first RBs. Claim: 3. The method of claim 1, wherein the configuration parameters indicate a second starting resource block (RB) of second RBs of the second CFR and a number of the second RBs. Claim: 4. The method of claim 1, further comprising receiving a second DCI in the active BWP, wherein: the second DCI is a wireless device specific DCI addressed to a cell-RNTI (C-RNTI) dedicatedly identifying the wireless device; the second DCI indicates a unicast transmission of a second transport block; and the second CFR is within the active BWP and outside of the first CFR of the MBS. Claim: 5. The method of claim 1, wherein the receiving the group common DCI is based on monitoring a downlink control channel for the group common DCI with cyclic redundancy check (CRC) bits, of the group common DCI, being scrambled by the RNTI for the MBS. Claim: 6. The method of claim 1, wherein the RNTI is a G-RNTI. Claim: 7. The method of claim 1, further comprising transmitting, by the wireless device, a first message indicating MBS. Claim: 8. A method comprising: transmitting, by a base station, one or more radio resource control (RRC) messages comprising: a radio network temporary identifier (RNTI) for multicast and broadcast services (MBS) of a cell; and configuration parameters of a first bandwidth part (BWP) and a second BWP of the cell, the configuration parameters comprising: a first parameter indicating a first location of first common frequency resources (CFR) for the MBS within the first BWP; and a second parameter indicating a second location of second CFR for the MBS within the second BWP; and transmitting, based on the RNTI, via an active BWP of the cell: a group common downlink control information (DCI) scheduling a transport block of the MBS, wherein: the group common DCI is received via the first CFR for the MBS based on the first BWP being the active BWP; or the group common DCI is received via the second CFR for the MBS based on the second BWP being the active BWP; and the transport block of the MBS. Claim: 9. The method of claim 8, wherein the configuration parameters indicate a first starting resource block (RB) of first RBs of the first CFR and a number of the first RBs. Claim: 10. The method of claim 8, wherein the configuration parameters indicate a second starting resource block (RB) of second RBs of the second CFR and a number of the second RBs. Claim: 11. The method of claim 8, further comprising receiving a second DCI in the active BWP, wherein: the second DCI is a wireless device specific DCI addressed to a cell-RNTI (C-RNTI) dedicatedly identifying the wireless device; the second DCI indicates a unicast transmission of a second transport block; and the second CFR is within the active BWP and outside of the first CFR of the MBS. Claim: 12. The method of claim 8, wherein the receiving the group common DCI is based on monitoring a downlink control channel for the group common DCI with cyclic redundancy check (CRC) bits, of the group common DCI, being scrambled by the RNTI for the MBS. Claim: 13. The method of claim 8, wherein the RNTI is a G-RNTI. Claim: 14. The method of claim 8, further comprising receiving, by the base station, a first message indicating MBS. Claim: 15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a base station, cause the base station to: transmit one or more radio resource control (RRC) messages comprising: a radio network temporary identifier (RNTI) for multicast and broadcast services (MBS) of a cell; and configuration parameters of a first bandwidth part (BWP) and a second BWP of the cell, the configuration parameters comprising: a first parameter indicating a first location of first common frequency resources (CFR) for the MBS within the first BWP; and a second parameter indicating a second location of second CFR for the MBS within the second BWP; and transmit, based on the RNTI, via an active BWP of the cell: a group common downlink control information (DCI) scheduling a transport block of the MBS, wherein: the group common DCI is received via the first CFR for the MBS based on the first BWP being the active BWP; or the group common DCI is received via the second CFR for the MBS based on the second BWP being the active BWP; and the transport block of the MBS. Claim: 16. The non-transitory computer-readable medium of claim 15, wherein the configuration parameters indicate a first starting resource block (RB) of first RBs of the first CFR and a number of the first RBs. Claim: 17. The non-transitory computer-readable medium of claim 15, wherein the configuration parameters indicate a second starting resource block (RB) of second RBs of the second CFR and a number of the second RBs. Claim: 18. The non-transitory computer-readable medium of claim 15, wherein the instructions further cause the base station to: receive a second DCI in the active BWP, wherein: the second DCI is a wireless device specific DCI addressed to a cell-RNTI (C-RNTI) dedicatedly identifying the wireless device; the second DCI indicates a unicast transmission of a second transport block; and the second CFR is within the active BWP and outside of the first CFR of the MBS. Claim: 19. The non-transitory computer-readable medium of claim 15, wherein receiving the group common DCI is based on monitoring a downlink control channel for the group common DCI with cyclic redundancy check (CRC) bits, of the group common DCI, being scrambled by the RNTI for the MBS. Claim: 20. The non-transitory computer-readable medium of claim 15, wherein the RNTI is a G-RNTI. Current International Class: 04; 04; 04
