Closed loop power control for PUSCH

An apparatus comprising:

• circuitry configured to receive signaling that enables transmit power control (TPC) accumulation, receive downlink control information (DCI) messages corresponding to respective physical uplink shared channel (PUSCH) transmission occasions, and transmit in the PUSCH transmission occasions in accordance with respective power control adjustment states;
• and
• circuitry configured to perform operations comprising determining the power control adjustment states for the PUSCH transmission occasions, wherein determining the power control adjustment states comprises selectively applying TPC accumulation to one or more of the power control adjustment states based on a determination that at least one of the PUSCH transmission occasions is out-of-order based on an arrival ordering of the DCI messages,
• wherein determining the power control adjustment states comprises determining whether a first PUSCH transmission occasion occurs out-of-order with respect to a second PUSCH transmission occasion based on an arrival ordering of the DCI messages, wherein the first PUSCH transmission occasion occurs before the second PUSCH transmission occasion, and
• wherein determining the power control adjustment states comprises determining a power control adjustment state by ignoring a TPC command in a DCI message corresponding to the first PUSCH transmission occasion based on a determination that the first PUSCH transmission occasion occurs out-of-order.

A system comprising:

• at least one processor;
• and
• a memory communicatively coupled to the at least one processor, the memory storing instructions which, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• receiving signaling that enables transmit power control (TPC) accumulation;
• receiving downlink control information (DCI) messages corresponding to respective physical uplink shared channel (PUSCH) transmission occasions;
• determining power control adjustment states for the PUSCH transmission occasions, wherein determining the power control adjustment states comprises selectively applying TPC accumulation to one or more of the power control adjustment states based on a determination that at least one of the PUSCH transmission occasions is out-of-order based on an arrival ordering of the DCI messages;
• and
• transmitting in the PUSCH transmission occasions in accordance with the power control adjustment states, wherein:
• a first PUSCH transmission occasion occurs before a second PUSCH transmission occasion,
• the second PUSCH transmission occasion occurs before a third PUSCH transmission occasion,
• the DCI message for the second PUSCH transmission occasion arrives before the first PUSCH transmission occasion,
• the DCI message for the second PUSCH transmission occasion arrives before the DCI message for a third PUSCH transmission occasion, and
• the DCI message for the first PUSCH transmission occasion arrives before the DCI message for the third PUSCH transmission occasion,
• wherein determining the power control adjustment states comprises determining a first power control adjustment state corresponding to the first PUSCH transmission occasion, determining a second power control adjustment state corresponding to the second PUSCH transmission occasion, and determining a third power control adjustment state corresponding to the third PUSCH transmission occasion,
• wherein the third power control adjustment state is based on i) a TPC command in the DCI message for the third PUSCH transmission occasion and ii) the second power control adjustment state, and
• wherein the second power control adjustment state is not accumulative of a previous state, and wherein the second power control adjustment state is given by a TPC command absolute value indicated in the DCI message for the second PUSCH transmission occasion.
