摘要

A method and apparatus provide for receiving a transmit power control command related to a physical uplink shared channel transmission having more than one scheduled transmission repetitions. An applicability of at least a portion of a power adjustment to less than all of the repetitions of the physical uplink shared channel transmission is determined. The physical uplink shared channel transmission is transmitted during each of the more than one scheduled transmission repetitions, wherein the at least the portion of the power adjustment is selectively applied as determined to the specified less than all of the more than one scheduled transmission repetitions.

說(shuō)明書(shū)

  • Updated upon reception of the special power control command;
  • Not updated (following Rel-15 rule above); otherwise

    • This disclosure discusses some of the new PC and PHR aspects for URLLC traffic and provides proposals for those new aspects. In particular, proposals are disclosed for the following issues:

      • Timing aspects of power headroom report (PHR) operation for out-of-order scheduling,
        • including: whether and/or how to modify the PHR “cut-off time” and possibly the selection of the PUSCH transmission that carries the PHR.
      • Power control enhancements for inter-UE multiplexing
        • including: mechanisms for dynamic power boosting via TPC command indication, etc.

    According to some embodiments, PHR timing are as follows:

      • Conservative PHR timeline: report PHR on the PUSCH corresponding to earliest DCI (even if it is not the earliest PUSCH). The PHR cut-off time as in Rel-15.
      • Aggressive PHR timeline: report PHR on the earliest available/earliest possible PUSCH. The PHR cut-off time is the reception time of the corresponding UL DCI/time-reference.
