Abstract:
One embodiment of the present specification provides a method for transmitting network support information in a serving cell in order to remove interference of a terminal. The method for transmitting the network support information comprises the steps of: enabling the serving cell to select a first terminal and a second terminal to which a multi-user multiple input multiple output (MU-MIMO) is applied; enabling the serving cell to select different codewords for a downlink data channel to the selected first and second terminals; enabling the serving cell to determine whether the first terminal can remove the interference; and transmitting, to the first terminal, the network support information for supporting the interference removal using the downlink data channel to the second terminal if the first terminal can remove the interference.
Abstract:
One embodiment of the present specification provides an interference-removed reception method. The interference-removed reception method may comprise the steps of: encoding, in a binary in a physical channel, stored information for an attacker cell which causes interference; performing a comparison between the encoded binary and a new binary in the physical channel received from the attacker cell; and if the binaries match, removing interference caused by the new binary in the physical channel received from the attacker cell by using the encoded binary, and thereby receiving a signal from a serving cell.
Abstract:
A method of reducing transmission power. The method is performed by a user equipment and includes calculating a maximum power reduction (MPR) on maximum output power for transmission with non-contiguous resource allocation in a single component carrier; and transmitting a signal based on the MPR. The MPR is determined according to the following equation: MPR=CEIL {MA, 0.5}, the CEIL being a function of rounding up by 0.5. The MA is determined according to the following equations: MA=(8.0−10.12*A) when 0
Abstract:
A method of providing information for cell measurements. A first cell configures a subframe for performing a first measurement with respect to a first cell. A first position performing the first measurement is different from a second position performing a second measurement with respect to a second cell. The method includes transmitting, from the first cell to a user equipment (UE), first pattern information indicating the first position and second pattern information indicating the second position. A first subframe corresponding to the first pattern information is included in non-Almost Blank Subframe (ABS) subframes of the first cell, and a second subframe corresponding to the second pattern information is included in ABS subframes of the first cell. The ABS subframes of the first cell are configured as a first subframe at each of 8 subframes of the first cell.

One disclosure of the specification provides a method performed by UE. The method comprises the steps of: receiving a synchronization signal from a network; on the basis of the UE being connected to a base station via an NTN satellite, receiving, from the network, system information related to an NTN; transmitting a RACH to the network; receiving a RA response message from the network; receiving measurement information from the network, wherein the measurement information includes information regarding a measurement point in time for measurement by the UE; determining, on the basis of orbit information of a target satellite, a measurable point in time when an elevation angle of the target satellite exceeds a threshold value; on the basis of the measurement point in time being earlier than the measurable point in time, transmitting a failure message to the network; and carrying out measurement at the measurable point in time.
