Abstract: A method for operating a communications controller includes assigning one or more code domain elements (CDE) of a transmission zone to each user equipment (UE) of a plurality of UEs being served by the communications controller and operating in the transmission zone and having a transmission available. The method also includes transmitting downlink information located in the one or more CDEs to the UEs without utilizing dynamic control signaling.

Abstract: Embodiments are provided herein for increasing low density signature space for multiplexed transmissions for a plurality of users. The embodiments include generating a virtual signature using a combination operation on a plurality of basic signatures. The generated virtual signatures are provisioned as basic resource units (BRUs) for transmissions for corresponding users. The combination operation is a row-wise or column-wise permutation for combining, in each of the virtual signatures, rows or columns of corresponding basic signatures. The rows or columns represent sequences of frequency bands at one time interval or sequences of allocated time intervals at one frequency band. Alternatively, the combination operation is intra-basic resource unit (BRU) hopping. The embodiments also include generating a plurality of BRU sets comprised of virtual signatures. Each of the BRU sets is provisioned for a corresponding user.
