Abstract
Aspects of the disclosure provide techniques and apparatuses for using keep-alive signaling for network energy saving in an idle mode. A network entity can transmit a keep-alive signal (KAS) to reduce the energy consumption of a network when the network is in an idle mode. In some aspects, the KAS can be a reduced synchronization signal block (SSB) that is sent more frequently than a full SSB. In some aspects, the KAS can have a different beam sweeping pattern and/or beam width from the full SSB.
Claims28
A network entity for a wireless communication network, comprising:
- a memory;
- and
- one or more processors coupled to the memory,
- wherein the one or more processors are configured to:
- send a keep-alive signals (KAS) periodically, the KAS being configured to indicate a presence of a cell associated with the network entity in an energy saving mode;
- and
- send a periodic synchronization signal after sending a plurality of KASs in one or more previous periods, and skipping the KAS in a period in which the periodic synchronization signal is sent, the KAS consuming less communication resources than the periodic synchronization signal.
A method for wireless communication at a network entity, comprising:
- sending a keep-alive signal (KAS) periodically, the KAS being configured to indicate a presence of a cell associated with the network entity in an energy saving mode;
- and
- sending a periodic synchronization signal after sending a plurality of KASs in one or more previous periods, and skipping the KAS in a period in which the periodic synchronization signal is sent, the KAS consuming less communication resources than the periodic synchronization signal.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- a transceiver for wireless communication;
- and
- one or more processors coupled to the memory and the transceiver,
- wherein the one or more processors are configured to:
- receive a keep-alive signal (KAS) periodically, the KAS being configured to indicate a presence of a cell associated with a network entity in an energy saving mode;
- and
- receive a periodic synchronization signal after receiving a plurality of KASs in one or more previous periods, and skipping the KAS in a period in which the periodic synchronization signal is received, the KAS consuming less communication resources than the periodic synchronization signal.
A method for wireless communication at a user equipment (UE), comprising:
- receiving a keep-alive signal (KAS) periodically, the KAS being configured to indicate a presence of a cell associated with a network entity in an energy saving mode;
- and
- receiving a periodic synchronization signal after receiving a plurality of KASs in one or more previous periods, and skipping the KAS in a period in which the periodic synchronization signal is received, the KAS consuming less communication resources than the periodic synchronization signal.
