Abstract:
Embodiments described herein may include methods, systems, and apparatuses that support transmissions in wireless transmit and receive units (WTRUs) having reduced capabilities. Uplink transmissions and multimedia broadcast multicast service (MBMS) may be supported in WTRUs operating on a reduced bandwidth within an overall system bandwidth by receiving an uplink (UL) resource allocation within the reduced bandwidth, and sending a transmission over the UL resource allocation. The reduced bandwidth may include a small number of physical resource blocks (PRBs) that do not overlap with PRBs located on the band edge of the overall system bandwidth containing a system PUCCH. The UL resource may be located in both band edges of the reduced bandwidth, may be a PRB-pair in the same frequency of the reduced bandwidth, or may be a PRB-pair in a first slot in a first subframe and second slot in a second subframe of the reduced bandwidth.
