DOWNLINK CONTROL INFORMATION FOR RETRANSMISSION OF SEMI-PERSISTENTLY SCHEDULED PHYSICAL DOWNLINK SHARED CHANNELS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17643298 titled 'DOWNLINK CONTROL INFORMATION FOR RETRANSMISSION OF SEMI-PERSISTENTLY SCHEDULED PHYSICAL DOWNLINK SHARED CHANNELS

Simplified Explanation

The present disclosure describes techniques for transmitting downlink control information (DCI) to schedule retransmissions of semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that were not successfully received.

• The method involves receiving a DCI that schedules retransmission of at least two SPS PDSCHs that have hybrid automatic retransmission request (HARD) identifier (IDs).
• The method also involves receiving the retransmissions of the at least two PDSCHs.

Potential applications of this technology:

• This technology can be applied in wireless communication systems, particularly in the transmission of downlink control information for retransmissions of semi-persistently scheduled physical downlink shared channels.
• It can be used in various communication devices such as user equipment (UE) to improve the reliability and efficiency of data transmission.

Problems solved by this technology:

• The technology addresses the issue of unsuccessful reception of semi-persistently scheduled physical downlink shared channels.
• It provides a method for scheduling retransmissions of these channels using downlink control information, improving the overall reliability of data transmission.

Benefits of this technology:

• The technique allows for efficient scheduling of retransmissions, reducing the need for unnecessary retransmissions and optimizing the use of network resources.
• It improves the reliability of data transmission by ensuring that semi-persistently scheduled physical downlink shared channels that were not successfully received are retransmitted.

Original Abstract Submitted

Certain aspects of the present disclosure provide techniques for transmitting downlink control information (DCI) to schedule retransmissions of semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that were not successfully received. A method that may be performed by a user equipment (UE) includes receiving a downlink control information (DCI) that schedules retransmission of at least two semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that have hybrid automatic retransmission request (HARD) identifier (IDs); and receiving the retransmissions of the at least two PDSCHs.
