TERMINAL AND WIRELESS COMMUNICATION METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18502944 titled 'TERMINAL AND WIRELESS COMMUNICATION METHOD

Simplified Explanation

The patent application describes a terminal that receives information from a core network device and a base station to monitor downlink control channels for specific information related to the terminal's subgroup in a paging occasion.

  • The terminal receives an identifier of a subgroup of a paging occasion from a core network device.
  • The terminal receives system information from a base station indicating the total number of subgroups in the paging occasion and the number of paging occasions corresponding to one Paging Early Indication (PEI) monitoring occasion.
  • The control unit of the terminal monitors a physical downlink control channel (PDCCH) for first downlink control information (DCI) with a PEI field in the PEI monitoring occasion.
  • If the value of the PEI indicates the terminal's subgroup, the control unit monitors a PDCCH for second DCI in the paging occasion.
  • If the PEI is not detected or does not indicate the terminal's subgroup, the control unit does not monitor the PDCCH for the second DCI.
  • The number of bits for the PEI field is determined based on the total number of subgroups in the paging occasion and the number of paging occasions for one PEI monitoring occasion.

Potential applications of this technology:

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

Problems solved by this technology:

  • Efficient monitoring of downlink control channels in paging occasions
  • Reduction of unnecessary monitoring for terminals not belonging to the indicated subgroup

Benefits of this technology:

  • Improved resource utilization in wireless networks
  • Enhanced communication reliability for terminals in specific subgroups
  • Reduced power consumption for terminals monitoring downlink control channels


Original Abstract Submitted

A terminal includes: a receiving unit which receives, from a core network device, an identifier of a subgroup of a paging occasion to which the terminal belongs, and which receives, from a base station, system information including information for indicating a total number of subgroups of the paging occasion and information for indicating a number of paging occasions corresponding to one Paging Early Indication (PEI) monitoring occasion; and a control unit which performs monitoring of a physical downlink control channel (PDCCH) for first downlink control information (DCI) including a field of a PEI in the PEI monitoring occasion, wherein the control unit performs monitoring of a PDCCH for second DCI in the paging occasion in a case where a value of the PEI indicates the subgroup of the paging occasion to which the terminal belongs; and performs no monitoring of the PDCCH for the second DCI in the paging occasion in a case where the PEI is not detected, or a value of the PEI does not indicate the subgroup of the paging occasion to which the terminal belongs, and a number of bits for the field of the PEI is determined based on the information for indicating the total number of subgroups of the paging occasion and the information for indicating the number of paging occasions corresponding to the one PEI monitoring occasion.
