Claim of US Patent No. 10,750,450

1. A method in a User Equipment (UE) for power saving, comprising:determining a first time-frequency resource set and K1 signature sequences; and
monitoring the K1 signature sequences in the first time-frequency resource set;
wherein:
when any one of the K1 signature sequences is found in the first time-frequency resource set, the UE is woken up;
the K1 signature sequences are used for generating K1 radio signals respectively;
the first time-frequency resource set is one of K2 candidate time-frequency resource sets;
K1 and K2 are positive integers respectively;
at least one of K1 and K2 is greater than 1; and
when K1 is greater than 1, the K1 signature sequences correspond to K1 first-type terminal groups respectively, the K1 first-type terminal groups all include the UE, and one of the K1 radio signals is transmitted in the first time-frequency resource set;
wherein K2 is greater than 1, the K2 candidate time-frequency resource sets are one-to-one corresponding to K2 second-type terminal groups, only one given second-type terminal group of the K2 second-type terminal groups includes the UE, and the given second-type terminal group corresponds to the first time-frequency resource set.
