Abstract: The present invention provides a method for switching a working mode on a relay network, a base station, a relay node, and a communications system. A donor eNB (DeNB) sends an RN reconfiguration message to a relay node RN in frequency division duplex FDD mode, so that the RN switches from the FDD mode to a half-duplex frequency division duplex H-FDD mode. The DeNB receives an acknowledgment message sent by the RN in FDD mode. When the DeNB verifies, according to the RN reconfiguration message and the acknowledgement message, that the RN has already started to switch from the FDD mode to the H-FDD mode, the DeNB switches from the FDD mode to the H-FDD mode.

Abstract: The present disclosure relates to random access preamble transmission methods, apparatuses, and storage mediums. In one example method, a terminal device determines, based on a target sub-coverage area to which the terminal device belongs in a preset coverage area of a network device, target random access preamble format information corresponding to the target sub-coverage area. Then, the terminal device sends, to the network device on a target time-frequency resource indicated by target random access preamble time-frequency resource information corresponding to the target random access preamble format information, a random access preamble corresponding to the target random access preamble format information.

Abstract: User equipment receives at least one TAC that is broadcast by a network device, where the TAC includes geographical location information, and the geographical location information is used to indicate a geographical location of a preset location point in a TA corresponding to the TAC. The user equipment determines, based on the TAC and a tracking area list (TAL), whether the TAL needs to be updated. If it is determined that the TAL needs to be updated, the user equipment sends a tracking area update request to the network device. The user equipment receives a response message, of the tracking area update request, returned by the network device.

Abstract: A signal processing method and device includes obtaining spectral coefficients of a current frame of an audio signal, in which N sub-bands of the current frame comprises at least one of the spectral coefficients. A total energy of M successive sub-bands of the N sub-bands, a total energy of K successive sub-bands of the N sub-bands, and an energy of a first sub-band are obtained to determine whether to modify original envelope values of the M sub-bands. When the original envelope values of the M sub-bands are modified, encoding bits are allocated to each of the N sub-bands according to the modified envelope values of the M sub-bands.

Abstract: An audio encoding method and apparatus and an audio decoding method and apparatus are disclosed. During encoding of an audio channel signal of a current frame, whether a first target virtual loudspeaker and a second target virtual loudspeaker corresponding to an audio channel signal of a previous frame of the current frame meet a specified condition is first determined. When the first target virtual loudspeaker and the second target virtual loudspeaker meet the specified condition, a first encoding parameter of the audio channel signal of the current frame is determined based on a second encoding parameter of the audio channel signal of the previous frame, so that the audio channel signal of the current frame is encoded based on the first encoding parameter to obtain an encoding result, and the encoding result is written into a bitstream.

Abstract: In an audio signal processing method, a processing device obtains a current position relationship between a sound source and a listener. The processing device then obtains a current audio rendering function based on the current position relationship. When the current position relationship is different from a stored previous position relationship, the processing device adjusts an initial gain of the current audio rendering function based on the current position relationship and the previous position relationship, to obtain an adjusted gain of the current audio rendering function. The processing device then obtains an adjusted audio rendering function based on the current audio rendering function and the adjusted gain, and generates a current output signal based on a current input signal and the adjusted audio rendering function.
