Claim of US Patent No. 10,484,157

1. A method in a User Equipment (UE) supporting low-latency wireless communication, comprising:Step A: receiving a first signaling, the first signaling indicating at least one of the following:
first information: whether a target Reference Signal (RS) set is transmitted in a first Long Term Evolution (LTE) timeslot; and
second information: whether an RS pattern of the target RS set is a first pattern or a second pattern in a second LTE timeslot;
Step B: according to the indication of the first signaling, receiving the target RS set and a second data in the second LTE timeslot; and
Step B2 of Step B: according to the target RS set received in the second LTE timeslot, estimating a parameter of a wireless channel through which the second data passes;
wherein:
the target RS set comprises P RSs, P being a positive integer, and the P RSs are respectively mapped to P antenna ports;
the second data is transmitted by the P antenna ports;
the second LTE timeslot is an LTE timeslot that is behind the first LTE timeslot and continuous with the first LTE timeslot;
the first pattern is the RS pattern of the LTE downlink UE-specific Reference Signal (URS) in the LTE timeslot; and
the first information indicates that the target RS set is not transmitted in the first LTE timeslot, or the second information indicates that the RS pattern of the target RS set is the second pattern in the second LTE timeslot.
