Method and apparatus for frequency domain resource allocation for multicast downlink transmissions
Abstract
Embodiments of the present disclosure relate to frequency domain resource allocation for DL transmissions. According to some embodiments of the disclosure, a method performed by a UE may include: receiving, within a frequency region common to a group of UEs including the UE, a first DCI format with a CRC scrambled by a first RNTI for scheduling a DL transmission, wherein the first DCI format and the DL transmission are common to the group of UEs, and the payload size of the first DCI format is equal to the payload size of a fallback DCI format with a CRC scrambled by a second RNTI specific to the UE and monitored in a CSS; determining the size of an FDRA field in the first DCI format based on at least one of the bandwidth of the frequency region and the size of an FDRA field in the fallback DCI format; and receiving the DL transmission on a plurality of RBs within the frequency region according to the FDRA field in the first DCI format.
