Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive ephemeris information associated with a satellite and a timing advance parameter associated with the satellite. The UE may modify, based at least in part on the ephemeris information, at least one of: a downlink frequency tracking loop (FTL), or a downlink time tracking loop (TTL). The UE may receive a downlink signal from the satellite based at least in part on modifying the downlink FTL or the downlink TTL. Numerous other aspects are described.
Claims30
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive ephemeris information associated with a satellite and a timing advance parameter associated with the satellite;
- modify, based at least in part on the ephemeris information, at least one of:
- a downlink frequency tracking loop (FTL), or
- a downlink time tracking loop (TTL);
- and
- receive a downlink signal from the satellite based at least in part on modifying the downlink FTL or the downlink TTL.
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving ephemeris information associated with a satellite and a timing advance parameter associated with the satellite;
- modifying, based at least in part on the ephemeris information, at least one of:
- a downlink frequency tracking loop (FTL), or
- a downlink time tracking loop (TTL);
- and
- receiving a downlink signal from the satellite based at least in part on modifying the downlink FTL or the downlink TTL.
A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- receive ephemeris information associated with a satellite and a timing advance parameter associated with the satellite;
- modify, based at least in part on the ephemeris information, at least one of:
- a downlink frequency tracking loop (FTL), or
- a downlink time tracking loop (TTL);
- and
- receive a downlink signal from the satellite based at least in part on modifying the downlink FTL or the downlink TTL.
An apparatus, comprising:
- means for receiving ephemeris information associated with a satellite and a timing advance parameter associated with the satellite;
- means for modifying, based at least in part on the ephemeris information, at least one of:
- a downlink frequency tracking loop (FTL), or
- a downlink time tracking loop (TTL);
- and
- means for receiving a downlink signal from the satellite based at least in part on modifying the downlink FTL or the downlink TTL.
