Abstract: A resource allocation method is applied to a communication system based on massive MIMO. The method includes: A donor eNodeB detects whether a target terminal exists in a donor cell, where a correlation between a wireless air interface channel of the target terminal and a wireless air interface channel of a relay node is greater than a target threshold; and if the target terminal does not exist, the donor eNodeB determines, for the relay node through resource spatial multiplexing, one or more beams used for data backhaul, where the one or more beams are beams formed by a massive antenna array of the donor eNodeB through air interface beamforming.

Abstract: A coherent optical receiver, and an optical communication device and system, and relates to the field of optical communication. A polarization control component in the coherent optical receiver can deflect, driven by a feedback control circuit, a state of polarization of local oscillator light, and decompose the local oscillator light into two channels of light having equal or similar optical power. Therefore, the state of polarization of the local oscillator light is not deflected randomly and thereby coherent detection is not affected. Moreover, an azimuth of a half-wave plate device in the polarization control component can be deflected continuously, allowing continuous tracking and adjustment for the state of polarization of the local oscillator light.

Abstract: A data transmission method for to a data center including a first site and a second site is disclosed. According to the data transmission method, after obtaining a first data packet sent by a virtual machine at the first site, a switch at the first site identifies a service type of the first data packet, and determines routing information of the first data packet based on the service type of the first data packet; and after determining the routing information, the switch sends the first data packet based on the routing information, where the routing information is used to indicate a bearer link for transmitting the first data packet, and a link through which the first data packet is transmitted to the second site is the bearer link. In this way, the first data packet may be transmitted through a link that corresponds to the service type of the first data packet.
