METHOD AND APPARATUS FOR DISCONTINUOUS RECEPTION FOR A GROUP OF USER EQUIPMENTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18350651 titled 'METHOD AND APPARATUS FOR DISCONTINUOUS RECEPTION FOR A GROUP OF USER EQUIPMENTS

Simplified Explanation

The abstract describes a method and apparatus for discontinuous reception (DRX) in a wireless communication system. The method involves a user equipment (UE) receiving higher layer parameters and determining DRX ON durations based on these parameters and reception occasions for physical downlink control channels (PDCCHs). The first PDCCH provides a downlink control information (DCI) format. The UE receives the first PDCCH in at least one reception occasion and determines, based on an indication in the DCI format, whether to receive a second PDCCH in at least one DRX ON duration from consecutive NDRX ON durations that are after the reception of the first PDCCH.

  • The method involves a UE in a wireless communication system.
  • The UE receives higher layer parameters and determines DRX ON durations based on these parameters and reception occasions for PDCCHs.
  • The first PDCCH provides a DCI format.
  • The UE receives the first PDCCH in at least one reception occasion.
  • The UE determines, based on an indication in the DCI format, whether to receive a second PDCCH in at least one DRX ON duration from consecutive NDRX ON durations.

Potential applications of this technology:

  • Wireless communication systems
  • Mobile networks
  • Internet of Things (IoT) devices

Problems solved by this technology:

  • Efficient power management in wireless communication systems
  • Optimizing reception of control information in PDCCHs
  • Reducing power consumption of UEs

Benefits of this technology:

  • Improved battery life for UEs
  • Enhanced network efficiency
  • Better utilization of network resources


Original Abstract Submitted

Methods and apparatuses for discontinuous reception (DRX) for a group of user equipments (UEs). A method of a UE in a wireless communication system includes receiving higher layer parameters and determining DRX ON durations based on the higher layer parameters and reception occasions for physical downlink control channels (PDCCHs) based on the higher layer parameters, wherein a first PDCCH from the PDCCHs provides a downlink control information (DCI) format. The method further includes receiving the first PDCCH in at least one reception occasion from the reception occasions and determining based on an indication in the DCI format, whether to receive a second PDCCH in at least one DRX ON duration from consecutive NDRX ON durations that are after the reception of the first PDCCH, wherein the indication in the DCI format is a bitmap of size N, and Nbits in the bitmap are respectively associated with the NDRX ON durations.
