Group common pdcch design in nr

A user equipment (UE) of a wireless communication system, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• receive symbols in a first time slot, the first time slot including a control region and a data region;
• attempt to detect, when the UE is configured to detect, a group common downlink control channel carried by the received symbols, the group common downlink control channel containing common information directed to a group of UEs including the UE;
• and
• when the detection is successful, determine, based on the common information, at least one of
• (a) a first slot configuration of one or more time slots,
• (b) a puncture configuration indicating one or more punctured symbols received in a second time slot, the one or more punctured symbols being initially allocated for carrying enhanced Mobile Broadband (eMBB) data and carrying Ultra-Reliable and Low Latency Communications (URLLC) data, the second time slot being prior to the first time slot,
• (c) a transmission burst duration of a transmission on an unlicensed link, the unlicensed link being in an unlicensed spectrum, and
• (d) one or more sub-regions of the control region containing one or more of the received symbols that are a part of a downlink data channel, the downlink data channel including one or more of the received symbols in the data region.

A computer-readable medium storing computer executable code for a wireless communication system including a user equipment (UE), comprising code to:

• receive symbols in a first time slot, the first time slot including a control region and a data region;
• attempt to detect, when the UE is configured to detect, a group common downlink control channel carried by the received symbols, the group common downlink control channel containing common information directed to a group of UEs including the UE;
• and
• when the detection is successful, determine, based on the common information, at least one of
• (a) a first slot configuration of one or more time slots,
• (b) a puncture configuration indicating one or more punctured symbols received in a second time slot, the one or more punctured symbols being initially allocated for carrying enhanced Mobile Broadband (eMBB) data and carrying Ultra-Reliable and Low Latency Communications (URLLC) data, the second time slot being prior to the first time slot,
• (c) a transmission burst duration of a transmission on an unlicensed link, the unlicensed link being in an unlicensed spectrum, and
• (d) one or more sub-regions of the control region containing one or more of the received symbols that are a part of a downlink data channel, the downlink data channel including one or more of the received symbols in the data region.
