Listen before talk sequence design for wireless communication

An apparatus of wireless communication of a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor being configured to:
• receive a transmission in a subset of symbols from at least one UE, each transmission including at least one concatenated sequence in each symbol of the subset of symbols for transmission collision avoidance;
• determine a set of resource blocks (RBs) on which each transmission is received from the at least one UE;
• and
• receive data on each determined set of RBs associated with each UE of the at least one UE, the transmission and the data being received on at least one subframe;
• wherein each symbol of the subset of symbols is associated with at least one subchannel, each of the at least one subchannel extends across x RBs, and each sequence of the at least one concatenated sequence from an ith UEi of the at least one UE is received in each symbol of the subset of symbols within a different subchannel of the at least one subframe.

An apparatus of wireless communication of a user equipment (UE), comprising:

• means for receiving a transmission in a subset of symbols from at least one UE, each transmission including at least one concatenated sequence in each symbol of the subset of symbols for transmission collision avoidance;
• means for determining a set of resource blocks (RBs) on which each transmission is received from the at least one UE;
• and
• means for receiving data on each determined set of RBs associated with each UE of the at least one UE, the transmission and the data being received on at least one subframe;
• wherein each symbol of the subset of symbols is associated with at least one subchannel, each of the at least one subchannel extends across x RBs, and each sequence of the at least one concatenated sequence from an ith UEi of the at least one UE is received in each symbol of the subset of symbols within a different subchannel of the at least one subframe.

• determine a set of resource blocks (RBs) on which each transmission is received from the at least one UE;
• and
• receive data on each determined set of RBs associated with each UE of the at least one UE, the transmission and the data being received on at least one subframe;
• wherein each symbol of the subset of symbols is associated with at least one subchannel, each of the at least one subchannel extends across x RBs, and each sequence of the at least one concatenated sequence from an ith UEi of the at least one UE is received in each symbol of the subset of symbols within a different subchannel of the at least one subframe.
