Paging and random access response (RAR) scheduling and DCI format
Methods and apparatus are provided for paging and random access response (RAR) scheduling and downlink control information (DCI) for a user equipment (UE). In one novel aspect, an SI-paging and a call-paging are transmitted separately, and scheduled by SI-Paging-DCI and call-Paging-DCI respectively. In one embodiment, a special PO is introduced for stand-alone SI-Paging scheduled by SI-Paging-DCI, and the special PO is different from the PO for call-Paging. In another novel aspect, SI-Paging is scheduled together with call-paging in the same PDSCH scheduled by call-Paging-DCI. In one embodiment, the SI-paging carries a value tag and a bitmap, wherein the value tag indicates whether any SI updates, and the bitmap indicates which one or more SIs updates. In another embodiment, the SI-Paging carries several valuetags, and the number of valuetag corresponds to the number of SI. The UE compares a current valuetag to a stored valuetag to verify whether a SI changes.
