Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a frequency associated with a synchronization signal block (SSB) associated with a base station. The UE may generate a security key associated with a handover of the UE based at least in part on the frequency associated with the SSB. Numerous other aspects are provided.
Claims35
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving, from a network entity, a communication, identifying a plurality of frequencies, on a downlink channel, wherein the communication indicates a particular frequency, of the plurality of frequencies and associated with a synchronization signal block (SSB) associated with the network entity, as an absolute radio frequency channel number (ARFCN) of the downlink channel;
- identifying, based at least in part on receiving the communication, the particular frequency, of the plurality of frequencies and associated with the SSB, as the ARFCN of the downlink channel;
- and
- generating a security key associated with a handover of the UE based at least in part on the particular frequency associated with the SSB.
A method of wireless communication performed by a network entity, comprising:
- receiving, from another network entity, an indication of a frequency, associated with a synchronization signal block (SSB);
- and
- generating a security key based at least in part on the frequency;
- and
- transmitting, to the other network entity, an indication that the frequency, associated with the SSB, was used for purposes of generating a security key associated with a handover of a user equipment.
A method of wireless communication performed by a network entity, comprising:
- identifying a frequency associated with a synchronization signal block (SSB) associated with a user equipment (UE);
- transmitting, to another network entity, a communication identifying the frequency associated with the SSB as an absolute radio frequency channel number (ARFCN) for purposes of generating a security key associated with the UE;
- and
- receiving, based at least in part on transmitting the communication and from the other network entity, an indication that the frequency associated with the SSB was used as the ARFCN for purposes of generating a security key associated with the user equipment and the other network entity.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive, from a network entity, a communication, identifying a plurality of frequencies, on a downlink channel, wherein the communication indicates a particular frequency, of the plurality of frequencies and associated with a synchronization signal block (SSB) associated with the network entity, as an absolute radio frequency channel number (ARFCN) of the downlink channel;
- identify, based at least in part on receiving the communication, the particular frequency, of the plurality of frequencies and associated with the SSB, as the ARFCN of the downlink channel;
- and
- generate a security key associated with a handover of the UE based at least in part on the particular frequency associated with the SSB.
A network entity for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the memory and the one or more processors configured to:
- receive, from another network entity, an indication of a frequency associated with a synchronization signal block (SSB);
- generate the security key based at least in part on the frequency;
- and
- transmit, to the other network entity, an indication that the frequency, associated with the SSB, was used for purposes of generating a security key associated with a handover of a user equipment.
