Abstract: A signal sending and receiving method and an apparatus is described. The method includes: receiving, by a terminal device, a first downlink signal from a network device in a first time unit of a first carrier, where the first carrier is a TDD carrier; determining, based on the first time unit, a second time unit used to send first feedback information for the first downlink signal on a second carrier, where the second carrier is an FDD uplink carrier; and sending the first feedback information to the network device on the second last symbol and/or the last symbol of the second time unit of the second carrier. Feedback information for a downlink signal on the first carrier is sent on the second carrier, so that a requirement of sending an uplink signal on the first carrier by the terminal device is reduced, thereby improving data transmission efficiency.

Abstract: Embodiments of the present disclosure provide a backoff window adjustment method, and an apparatus. In downlink transmission, a base station obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the base station on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel. In uplink transmission, a user equipment (UE) obtains a trigger condition for adjusting a length of a backoff window on a first channel, and adjusts the length of the backoff window of the UE on the first channel according to the obtained trigger condition for adjusting the length of the backoff window on the first channel.

Abstract: To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE.

Abstract: Embodiments of the present invention disclose an interference suppression method and a related device and system. The method includes: sending, on a specified time-frequency resource, a first reference signal or a first reference signal group to an interfered-with end; receiving interfering source information sent by the interfered-with end, where the interfering source information includes an interference identifier used for indicating whether a potential interfering source causes interference to the interfered-with end; and if the interference identifier in the interfering source information indicates that the potential interfering source sending the reference signal on the specified time-frequency resource causes interference to the interfered-with end, determining that the potential interfering source is an interfering source, otherwise, determining that the potential interfering source is a non-interfering source. According to the present invention, mutual interference between uplink and downlink signals of terminals located in a same cell or different cells can be suppressed.
