Abstract
The present application relates to devices and components including apparatus, systems, and methods for configuring and using multicast or broadcast services resource sets.
Claims13
A method comprising:
- receiving first configuration information that configures a multicast or broadcast service (MBS) initial bandwidth part (BWP) and a first control resource set (CORESET), wherein the MBS initial BWP has a first bandwidth that is larger than a second bandwidth of an initial downlink BWP, and the second bandwidth is encompassed by the first bandwidth;
- prior to receiving second configuration information, monitoring the first CORESET for a first MBS physical downlink control channel (PDCCH) transmission that schedules a first MBS physical downlink shared channel (PDSCH) transmission in the MBS initial BWP;
- receiving the second configuration information that configures an MBS BWP and a second CORESET, wherein the MBS BWP includes a third bandwidth that is larger than the first bandwidth, and the first bandwidth is encompassed by the third bandwidth;
- and
- after receiving the second configuration information, monitoring the second CORESET for a second MBS PDCCH transmission that schedules a second MBS PDSCH transmission in the MBS BWP.

A method comprising:
- generating, for transmission to a user equipment (UE), first configuration information to configure the UE with a multicast or broadcast service (MBS) initial bandwidth part (BWP) and a first control resource set (CORESET), wherein MBS initial BWP has a first bandwidth that is larger than a second bandwidth of an initial downlink BWP, and the second bandwidth is encompassed by the first bandwidth;
- generating, for transmission to the UE, second configuration information that configures an MBS BWP and a second CORESET, wherein the second configuration information is received after the first configuration information, the MBS BWP includes a third bandwidth that is larger than the first bandwidth, and the first bandwidth is encompassed by the third bandwidth;
- generating, for transmission to the UE, an MBS physical downlink control channel (PDCCH) transmission to schedule an MBS physical downlink shared channel (PDSCH) transmission, wherein the MBS PDCCH transmission is within the first CORSET and the MBS PDSCH transmission is within the MBS initial BWP or the MBS PDCCH transmission is within the second CORESET and the MBS PDSCH transmission is within the MBS BWP;
- and
- generating, for transmission to the UE, the MBS PDSCH transmission with MBS service data as scheduled by the MBS PDCCH transmission.
2 more elements
One or more non-transitory, computer-readable media having instructions that, when executed, cause processing circuitry to:
- process first configuration information that configures a multicast or broadcast service (MBS) initial bandwidth part (BWP) and a first control resource set (CORESET), wherein MBS initial BWP has a first bandwidth that is larger than a second bandwidth of an initial downlink BWP and the second bandwidth is encompassed by the first bandwidth;
- prior to receipt of second configuration information, monitor the first CORESET for a first MBS physical downlink control channel (PDCCH) transmission to schedule a first MBS physical downlink shared channel (PDSCH) transmissions in the MBS initial BWP;
- process the second configuration information that configures an MBS BWP and a second CORESET, wherein the MBS BWP includes a third bandwidth that is larger than the first bandwidth, and the first bandwidth is encompassed by the third bandwidth;
- and
- after receipt of the second configuration information, monitor the second CORESET for a second MBS PDCCH transmission that schedules a second MBS PDSCH transmission in the MBS BWP.
