    Abstract: A millimeter-wave (mmWave) assembly (1) comprising a first mmWave module (2), a second mmWave module (3), and a connector (4) configured to releasably interconnect the first mmWave module (2) and the second mmWave module (3). The connector (4) comprises a first connector element (5) associated with the first mmWave module (2). The first mmWave module (2) comprises a first substrate (7) and an mmWave radio frequency integrated circuit (RFIC) (8), and the second mmWave module (3) comprises a second substrate (9) and an mmWave antenna array (10). The connector (4) is configured to transmit at least one signal between the mmWave RFIC (8) and the mmWave antenna array (10) when the first mmWave module (2) and the second mmWave module (3) are interconnected.

    Abstract: A beam management method includes: A terminal device determines a first UE posture of the terminal device in a process in which the terminal device receives, by using a first receive beam, information sent by a network device, where the terminal device includes a plurality of receive beams; when the terminal device is changed from the first UE posture to a second UE posture, the terminal device determines a second receive beam based on a direction relationship between the plurality of receive beams and a direction change status during a change from the first UE posture to the second UE posture; and the terminal device receives, by using the second receive beam, the information sent by the network device.

    Abstract: A cell search method and a communication apparatus. The method comprises: before performing cell search, a terminal device can determine, in combination with the historical access information of other terminal device, whether a cell exists at the position, and adjusts, according to the determination result, the value of the search parameter for cell search, for example, if a cell exists, the search is accelerated by adjusting the search parameter; if no cell exists, the search may not be performed or the search parameter may not be adjusted, so as to reduce unnecessary cell search performed by the terminal device, so that the power consumption of the terminal device can be reduced.

    Abstract: An apparatus and associated method are provided involving a housing having a periphery configured to operate as a second antenna, a third antenna, and a fourth antenna. The periphery includes a top wall having a first slot formed therein, a first side wall having a second slot formed therein, and a second side wall having a third slot formed therein. The top wall is arranged between the first side wall and the second side wall, and a top portion of the periphery is defined between the second slot and the third slot. The top portion is divided into a first top side portion and a second top side portion via the first slot. Further, the first top side portion operates as the second antenna, and the second top side portion operates as both the third antenna and the fourth antenna.

    Abstract: Embodiments of the present invention provide a transmitter. The transmitter includes: a dual-band input circuit including at least two band input ends, performing DPD processing on an input baseband signal, and outputting the baseband signal; a modulo circuit, performing modulo processing on the input baseband signal, and outputting the baseband signal; a signal decomposition circuit, receiving the baseband signal input by the dual-band input circuit and a baseband signal modulus value input by the modulo circuit, and performing decomposition to obtain multiple decomposed signals; a modulation circuit, receiving the multiple decomposed signals, performing processing, modulating two signals obtained after processing to corresponding working frequencies, and outputting the two signals to a dual-band power amplifier. In comparison with a single-input dual-band power amplifier, when a dual-input dual-band power amplifier transmits signals in two bands concurrently, overall transmission efficiency of a dual-band transmitter can be obviously improved.
