  • Publication number: 20250048261
    Abstract: Methods and systems are provided for NES (network energy savings) operations in a network. A network node may transmit to user equipments (UEs) an indication about an NES operation activation for one or more cells. The UE(s) may send a reconfiguration request to modify the NES operation for one or more cells, for example to avoid a degradation in service that may negatively impact key performance indicators or quality of experience. In response, the network node may modify the NES operation. The network node may then send an updated indication about the modified NES operation for the one or more cells.

  • Publication number: 20240381440
    Abstract: Systems and methods for enabling energy efficient Random Access Channel (RACH) are provided. A method performed by a network node includes one or more of: being configured with an original RACH configuration; receiving a preamble in a RACH Occasion; dynamically changing a RACH-configuration period and/or RACH frequency multiplexing configuration according to whether a preamble was received; reconfiguring to a performance optimized configuration; starting one or more timers: keeping the current RACH configuration until the timer(s) reaches the specified time; if fewer than a threshold preambles are received, reconfiguring with the original PRACH configuration; and if more than a threshold preamble are received, resetting and/or restarting a running timer. An energy efficient RACH configuration allows the network node receivers to have a longer sleep time and operate over a narrower bandwidth. As such more energy is saved when the network is in idle mode and there are no/little RACH attempts.

  • Patent number: 12143933
    Abstract: Embodiments include methods, performed by a user equipment (UE), for communication with a network node in a radio access network (RAN). Such methods include receiving, from the network node, an indication that a minimum scheduling offset, between a scheduling physical downlink control channel (PDCCH) and a signal or channel scheduled via the scheduling PDCCH, will change after a first duration. Such methods also include subsequently monitoring, during the first duration, for a scheduling PDCCH based on a first operating configuration; and in response to the end of the first duration, monitoring for a scheduling PDCCH based on a second operating configuration. The first duration can be related to time required, by the UE, to switch from the first to the second operating configuration. Embodiments also include UEs configured to perform such methods.
