Tracking loop design for unicast and multicast/broadcast signals
First Claim
1. A method of wireless communication, comprising:
- maintaining a first set of tracking loops associated with unicast signals, the first set of tracking loops comprising a time tracking loop (TTL) and a frequency tracking loop (FTL), the TTL being maintained based on a timing offset and the FTL being maintained based on a frequency offset;
maintaining a second set of tracking loops associated with multicast/broadcast signals; and
decoding at least one of a received unicast signal based on the first set of tracking loops or a received multicast/broadcast signal based on the second set of tracking loops,wherein the timing offset and the frequency offset are based on at least one of cell-specific reference signals (CRS), channel state information reference signals (CSI-RS), or user equipment specific reference signals (UE-RS) within the received unicast signal.

Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. In a first configuration, the apparatus maintains a first set of tracking loops associated with unicast signals and a second set of tracking loops associated with multicast/broadcast signals. In addition, the apparatus decoding at least one of a received unicast signal based on the first set of tracking loops or a received multicast/broadcast signal based on the second set of tracking loops. In a second configuration, the apparatus maintains a TTL and a FTL associated with unicast signals based only on received unicast signals. In addition, the apparatus receives a multicast/broadcast signal and decodes the received multicast/broadcast signal based on the TTL and the FTL maintained based only on the received unicast signals.
