Abstract
Embodiments include methods for cell reselection by a user equipment (UE) in a wireless network. Such methods include determining one or more first resources associated with transmission of connected-state reference signals (RS) by the wireless network in the UE's serving cell and/or in one or more neighbor cells while the UE is in a non-connected state. Such methods include using the one or more first resources, performing cell reselection measurements on the connected-state RS transmitted in the serving cell and/or in any of the neighbor cells. Other embodiments include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.
Claims20
A method for cell reselection by a user equipment (UE) configured to operate in a wireless network, the method comprising:
- estimating a first expected energy consumption associated with cell reselection measurements based on the connected-state RS;
- estimating a second expected energy consumption associated with cell reselection measurements based on synchronization signal/PBCH block (SSB);
- determining one or more first resources associated with transmission of connected-state reference signals (RS) by the wireless network in the UE's serving cell and/or in one or more neighbor cells while the UE is in a non-connected state, wherein the one or more first resources are determined based on performing blind decoding of system information (SI) broadcast in the one or more neighbor cells;
- and
- based on the first expected energy consumption being less than the second expected energy consumption and using the one or more first resources, performing cell reselection measurements on the connected-state RS transmitted in the serving cell and/or in any of the neighbor cells.
A user equipment (UE) configured to perform cell reselection in a wireless network, the UE comprising:
- radio transceiver circuitry configured to communicate with a network node via a serving cell;
- and
- processing circuitry operatively coupled to the radio transceiver circuitry, whereby the processing circuitry and the radio transceiver circuitry are configured to:
- estimate a first expected energy consumption associated with cell reselection measurements based on the connected-state RS;
- estimate a second expected energy consumption associated with cell reselection measurements based on synchronization signal/PBCH block (SSB);
- determine one or more first resources associated with transmission of connected-state reference signals (RS) by the wireless network in the UE's serving cell and/or in one or more neighbor cells while the UE is in a non-connected state, wherein the one or more first resources are determined based on performing blind decoding of system information (SI) broadcast in the one or more neighbor cells;
- and
- based on the first expected energy consumption being less than the second expected energy consumption and using the one or more first resources, perform cell reselection measurements on the connected-state RS transmitted in the serving cell and/or in any of the neighbor cells.
