Aspects described herein relate to identifying an aggressor node that transmits interfering signals that cause interference to signals received at the node, communicating a configuration for applying a phase shift to the interfering signals for forwarding to the node from a reflecting node with the phase shift applied, and communicating, from the reflecting node, the interfering signals with the phase shift applied to at least partially cancel the interference to the signals received at the node.

Techniques are provided for a delay compensated analog beam forming network. A transceiver implementing the techniques according to an embodiment includes an array of circuit elements. Each of the circuit elements includes an analog frequency converter to up-convert an analog signal to radio frequency (RF) for transmission and to down-convert an RF signal to an analog signal for reception. The circuit element also includes an analog beam weighting circuit configured to apply a beam weight to both of the analog signals to form a beam for transmission and reception. The circuit element further includes an analog delay element configured to impart a time delay to the analog signals. The time delay is based on the position of the circuit element in the array and is selected to compensate for propagation delay of the analog signals along the electrical path that couples the circuit elements of the array, reducing beam squint.

A method to reduce a probability of occurrence of a hidden node in a data transmission process in a high-frequency system is disclosed. The method implemented by a communications apparatus includes determining at least one beam to be used for sending a resource reservation message, where the at least one beam includes a first beam, where a direction of the first beam is opposite to a direction of a second beam, and where the direction of the second beam is a potential transmission direction in which the communications apparatus sends information. The method further includes sending the resource reservation message by using the at least one beam, where the resource reservation message includes a resource reservation request message or a resource reservation response message, where the resource reservation request message is used to request to reserve a transmission resource, and where the resource reservation response message is used to determine to reserve a transmission resource.

Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.
