Variable cyclic prefix (CP) within a transmission slot in millimeter wave band

An apparatus comprising:

• a processor configured to identify a first cyclic prefix (CP) configuration for a transmission period;
• and
• a transceiver configured to communicate, with a first wireless communication device during the transmission period, a first communication signal including a first plurality of symbols, wherein each of the first plurality of symbols include an individually configurable cyclic prefix (CP) length configured based on the first CP configuration, wherein a first symbol of the first plurality of symbols includes a first CP length and a second symbol of the first plurality of symbols includes a second CP length that is longer than the first CP length, and wherein a demodulation reference signal (DMRS) is included within the second symbol.

A computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to identify a first cyclic prefix (CP) configuration for a transmission period;
• and
• code for causing the first wireless communication device to communicate, with a second wireless communication device during the transmission period, a first communication signal including a first plurality of symbols, wherein each of the first plurality of symbols include an individually configurable cyclic prefix (CP) length configured based on the first CP configuration, wherein a first symbol of the first plurality of symbols includes a first CP length and a second symbol of the first plurality of symbols includes a second CP length that is longer than the first CP length, and wherein a demodulation reference signal (DMRS) is included within the second symbol.
