Abstract: A multi-subscriber identity module (SIM) device including a first SIM for first wireless communication, a second SIM for second wireless communication, and a processor configured to allocate a radio frequency (RF) resource to any one of the first and second SIMs, control first uplink time alignment of the first wireless communication by allocating the RF resource to the first SIM, and adjust a first time alignment timer for the first uplink time alignment based on an RF resource allocation gap of the first SIM when the RF resource is allocated from the first SIM to the second SIM and the RF resource is reallocated from the second SIM to the first SIM may be provided.

Abstract: A method of operating a wireless communication terminal, which performs a hybrid automatic repeat request process for a plurality of subscriber identity modules (SIMs), includes: setting up communication with a plurality of base stations that respectively correspond to the plurality of SIMS; allocating a radio frequency resource to receive data from each base station corresponding to each SIM in an SIM allocation duration, wherein the SIM allocation duration is set corresponding to each of the plurality of SIMS in a multi-SIM allocation period, and wherein the multi-SIM allocation period corresponds to a data round trip time (RTT) of a base station of the plurality of base stations; and transmitting, with respect to the received data, one of an acknowledged (ACK) signal and a negative-ACK (NACK) signal to each base station corresponding to each SIM.

Abstract: A device for wireless communication of user equipment (UE) in a dual connection system includes a memory providing a buffer storing first data received from a first base station (BS) and second data received from a second BS and a first processor generating a radio bearer (RB) by reordering the first data and the second data and adjusting a size of the buffer based on a delay between the first BS and the second BS.
