摘要

In a wireless communication system, a user equipment (UE) transmits, to a base station (BS), UE capability information comprising whether the UE supports cooperative communication for receiving physical downlink shared channels (PDSCHs) from a plurality of transmission reception points (TRPs) in a particular time-frequency resource, obtains, via radio resource control (RRC), information about whether the cooperative communication is to be applied from the BS, identifies a format of a medium access control (MAC) control element (CE) received from the BS based on whether the BS is to apply the cooperative communication, and determines transmission configuration indication (TCI) states according to the respective TRPs, based on the identified format of the MAC CE.

說明書

A memory (not shown) may store programs and data that are required for operations of the UE. The memory may also store control information or data included in a signal obtained by the UE. The memory may be implemented as a storage medium including a read only memory (ROM), a random access memory (RAM), a hard disk, a compact disc (CD)-ROM, a digital versatile disc (DVD), or the like, or any combination thereof.

The UE processor 19-05 may control a series of procedures to operate the UE according to the afore-described embodiments of the disclosure. The UE processor 19-05 may be implemented as a controller or one or more processors.

FIG. 20 illustrates a structure of a BS according to some embodiments of the disclosure.

Referring to FIG. 20, the BS may include a BS receiver 20-00, a BS transmitter 20-10, and a BS processor 20-05. The BS receiver 20-00 and the BS transmitter 20-10 may be collectively called the transceiver. According to the aforementioned communication method performed by the BS, the BS receiver 20-00, the BS transmitter 20-10, and the BS processor 20-05 of the BS may operate. However, elements of the BS are not limited thereto. For example, the BS may include more elements (e.g., a memory) than the aforementioned elements or may include fewer elements than the aforementioned elements. Also, the BS receiver 20-00, the BS transmitter 20-10, and the BS processor 20-05 may be integrated to one chip.
