(54) Title: SHARING OF LONG-TERM EVOLUTION (LTE) UPLINK SPECTRUM (57) : Wireless communications systems and methods relat- 800 ed to performing initial network access procedures using shared re- sources are provided. A first wireless communication device transmits, in a first frequency band, a random access request to a first network. T 1 The first wireless communication device receives, in response to the random access request, a random access response from a second wire- less communication device of the first network. The random access response is in a second frequency band allocated to the first network for time-division duplexing (TDD) communications. The second fre- quency band is different than the first frequency band.
