Abstract: The present disclosure discloses a method and device in UE and base station used for wireless communications. A UE transmits a first radio signal, the first radio signal indicating a first reference signal out of M reference signals; and monitors a first signaling in each of W time-frequency resource block(s). Herein, at least one reference signal of the M reference signals is transmitted by a first serving cell, and the first serving cell is not added by the UE; the UE assumes that a transmission antenna port of the first signaling is Quasi-Co-Located with a transmission antenna port of the first reference signal; W is a positive integer, and M is a positive integer greater than 1. Such method can be employed to avoid delay and service interruption brought about by cell handover.

Abstract: The disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communication. The UE receives a first signaling and a first radio signal, and transmits first information; only X1 bit(s) in a first bit block is(are) used for generating the first radio signal, the first bit block is obtained as an output of channel coding of a first code block; the first signaling is used for determining that the X1 bit(s) cannot be used for decoding of the first code block with combining when channel decoding for the X1 bit(s) fails. Through the design of the first information, the disclosure implements the update of a state of buffer occupation of the UE or a state of channel decoding, to facilitate a base station to adjust a transmission policy in real time, thereby improving overall performances.
