CONNECTED-MODE DISCONTINUOUS RECEPTION (C-DRX) TIMER VALUE SELECTION BASED ON LOGICAL CHANNEL (LCH) MAPPING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240107524 titled 'CONNECTED-MODE DISCONTINUOUS RECEPTION (C-DRX) TIMER VALUE SELECTION BASED ON LOGICAL CHANNEL (LCH) MAPPING

Simplified Explanation

The patent application describes a method and apparatus for managing the quiescent state of a user equipment (UE) based on a connected-mode discontinuous reception (C-DRX) setting for uplink transmissions.

  • Receiving configuration information related to a logical channel (LCH) from a base station (BS)
  • Receiving an uplink grant for uplink data transmission
  • Identifying a subset of LCHs that can be mapped to the uplink grant
  • Determining a C-DRX setting for the uplink transmission based on the identified subset of LCHs
  • Controlling the quiescent state of the UE based on the C-DRX setting

The patent application discusses controlling the quiescent state of UEs based on C-DRX settings, but the actual impact on battery life in real-world usage remains to be seen.

        1. Are there any compatibility issues with existing network infrastructure when implementing these C-DRX settings?

It would be important to understand if there are any challenges or compatibility issues when integrating this technology with current network setups.


Original Abstract Submitted

a method and apparatus are provided for, in aspects, receiving, at a user equipment (ue), a configuration relating to a logical channel (lch) from a base station (bs); receiving, at the ue, an uplink grant for an uplink data; identifying a subset of the lch mappable to the uplink grant based on the at least a part of the configuration; determining, at the ue, a connected-mode discontinuous reception (c-drx) setting to be applied for an uplink transmission associated with the uplink grant based on the identified subset of the lch; and controlling a quiescent state of the ue based on the c-drx setting, wherein, in aspects, mappable may refer to allowed to be mapped or actually mapped. when lchs of the subset are associated with different c-drx settings, rule-based c-drx selection can be used.
