A method for emulating a communication system with fast changing link condition, applied to a testbed system including an interference emulator, a transmitter, and a receiver, includes: by the transmitter, generating code-word symbols, in an initial symbol sequence, according to information bits; evaluating an interference condition and a time duration for each code-word symbol; reordering the code-word symbols to a reordered symbol sequence based on interference conditions; evaluating a total time duration of code-word symbols under each interference condition; and transmitting the code-word symbols in the reordered symbol sequence. The method also includes: by the interference emulator, obtaining the total time duration of code-word symbols under each interference condition from the transmitter; and providing an emulated interference environment by ordering the time durations of different interference conditions. The start time for transmitting code-word symbols with an interference condition is synchronized with the start time for emulating the interference condition.

Aspects of the present disclosure relate to receiving, at a first node and from a second node configured for full-duplex wireless communications, a signal indicating an interference floor for receiving signals at the second node, wherein the interference floor is based on interference caused by a transmitter of the second node, determining, by the first node and based at least in part on the interference floor, a modulation and coding scheme (MCS) for transmitting one or more signals to the second node, and transmitting, by the first node and based on the MCS, the one or more signals to the second node.

The present invention discloses a method for configuring an operation mode of a remote transceiver unit connected to an access node via a communication line, the remote transceiver unit being operable in at least two operation modes: a Time Division Duplex, TDD, mode and a full duplex, FDX, mode; the method comprising, by the access node: a) obtaining a channel characteristic derived from channel measurements performed over the communication line, b) determining the operation mode of the remote transceiver unit as the FDX mode or the TDD mode based on the channel characteristic; c) transmitting an indication indicating the determined operation mode to the remote transceiver unit.

A modulation technique, such as for example either Pi/2 BPSK or QPSK, is selected for transmission, based on a characteristic of the data to be transmitted, or the physical channel over which it is to be transmitted. The data characteristic may be the coding rate, or characteristics indirectly related to the coding rate, such as the number of coded bits or number of uncoded bits (payload size). The physical channel characteristic may for example be the physical channel bandwidth, the physical channel length, a number of physical channel modulation symbols, a number of the physical channel resource elements used for the data to be transmitted, or a number of the physical channel modulation symbols carrying the data to be transmitted.

Techniques are described that provide for waveform selection for uplink (UL) and/or downlink (DL) wireless transmissions based on one or more factors associated with the wireless transmission, a transmitter that is to transmit the wireless transmission, or combinations thereof. UL and DL transmissions may use one of a number of different waveforms, such as single-carrier waveforms that use a single carrier for information transmission of a wireless channel, and multi-carrier waveforms that use multiple carriers at different frequencies to transmit some of the bits on each channel. Multi-carrier transmission waveforms or single-carrier waveforms may be selected for wireless transmissions based on a bandwidth allocated for the transmissions, a capability of a transmitter that is to transmit the transmissions, or combinations thereof.

A mobile communication device includes a table component, a table selection component, a control information component, and a communication component. The table component is configured to maintain two or more tables each having entries for a plurality of available modulation schemes.
