System and method for increasing low density signature space
First Claim
1. A method comprising:
- determining, by a user equipment (UE), a second signature of a plurality of second signatures for transmitting information over a shared channel, the second signature including at least two different predetermined first signatures that were selected for inclusion in the second signature from a plurality of first signatures based on a predetermined mapping rule, the selection of the at least two different predetermined first signatures for inclusion in the second signature being independent of the information to be transmitted over the shared channel, a number of second signatures in the plurality of second signatures being larger than a number of first signatures in the plurality of first signatures; and
transmitting, by the UE after determining the second signature, the information using the second signature over assigned channel resources of the shared channel.

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.
