Abstract
A wireless communication method includes configuring, by a wireless communication node, a first bandwidth part (BWP) to a first User Equipment (UE), wherein a multicast control channel (MCCH) for the first UE is transmitted in the first BWP; and configuring, by the wireless communication node, a second BWP to the first UE, wherein a multicast traffic channel (MTCH) for the first UE is transmitted in the second BWP.
Claims18
A method, comprising:
- configuring, by a wireless communication node, a first bandwidth part to a first wireless communication device, wherein a multicast control channel (MCCH) for the first wireless communication device is transmitted in the first bandwidth part, wherein the first bandwidth part is shared by the first wireless communication device with a second wireless communication device to transmit the MCCH;
- and
- configuring, by the wireless communication node, a second bandwidth part to the first wireless communication device, wherein a multicast traffic channel (MTCH) for the first wireless communication device is transmitted in the second bandwidth part,
- wherein at least one of the first bandwidth part, the second bandwidth part, or a third bandwidth part is shared by the first wireless communication device with the second wireless communication device, to transmit a MTCH for the second wireless communication device;
- and
- transmitting, by the wireless communication node, a first physical downlink shared channel (PDSCH) transmission on a first resource set to the first wireless communication device, and a second PDSCH transmission on a second resource set to the second wireless communication device, the first resource set includes at least a portion of shared resources with the second resource set in time domain and frequency domain of the first wireless communication device and the second wireless communication device,
- wherein the shared resources comprise a same data which is transmitted to the first wireless communication device and the second wireless communication device.
