  • Publication number: 20230199617
    Abstract: A communication system for enabling/disabling EDT comprises UEs and a network node. The network node is configured to collect measurements regarding cell information, determine whether EDT is allowed to be used by the UEs to transmit data prior to completing an access procedure, and send a message comprising an EDT indication instructing whether EDT is allowed to be used by the UEs. The UE is configured to initiate a transmission to the network node, receive the message comprising the EDT indication, and determine whether EDT is allowed to be used based on the EDT indication. The communication system may be able to enable or disable EDT for the UE based the status of cell, such that the communication system may avoid a resource waste caused by an early indication in Msg1 or a larger uplink grant in Msg2, and further improve the network performance.

  • Publication number: 20230043517
    Abstract: A method is disclosed herein for reducing energy consumption in a wireless device. A wireless device (e.g., a user equipment) can provide an indication to a network node (e.g., a base station) to indicate that the wireless device will prioritize energy consumption reduction over some network requirements (e.g., latency and/or scheduling flexibility requirements). Accordingly, the wireless device can perform certain power-saving actions to reduce energy consumption. The network node, upon receiving the indication from the wireless device, can perform certain network-related actions to assist the wireless device in reducing energy consumption. As a result, it is possible for the wireless device to reduce energy consumption and complexity, thus helping to prolong battery life in the wireless device.
