    Abstract: A detection apparatus concurrently connected to N optical module cages by using N paths. The apparatus accesses a conflict register, acquires an occupancy status of the N paths according to a value of the conflict register, then performs a concurrent probe on M optical module cages connected to M paths that are in the N paths and whose occupancy status are not occupied by system software, to obtain a probe result, where the probe result includes availability information of optical modules of the M optical module cages and a type of the optical modules, and finally, writes the probe result into an availability register, so that the system software can acquire the probe result from the availability register. Therefore, whether an optical module is available in an optical module cage can be monitored in real time and fast insertion and removal operations on the optical module can be sensed.

    Abstract: A network device sends downlink control information to a first terminal device. The downlink control information includes: time domain resource information, where the time domain resource is a time domain resource on which a first data channel is located; and frequency domain resource information, where the frequency domain resources are a frequency domain resource on which the first data channel is located and a frequency domain resource on which a second data channel is located. The second data channel is located on a time domain resource different from the time domain resource on which the first data channel is located. The first terminal device receives, on the determined time domain resource and frequency domain resource, a signal that is located on the first data channel and that is from the network device.

    Abstract: A method includes: When user equipment is in an RRC idle mode or inactive mode, the user equipment sends a first random access preamble to an access network device on a PRACH resource, and sends first uplink data to the access network device on a PUSCH resource. The user equipment sends, by using at least two beams respectively, SRSs to the access network device on at least two SRS resources associated with the PUSCH resource. The user equipment receives a random access response from the access network device, where the random access response includes beam indication information, and the beam indication information is used to indicate an optimal beam in the at least two beams.

    Abstract: This application discloses a communication method and an apparatus. A principle of the method is as follows: A spreading factor of a spreading block is adjusted based on available resource elements REs in a time-frequency resource block, then, the spreading block is generated by using the adjusted spreading factor, and finally, the generated spreading block is mapped to the available resource elements in the time-frequency resource block for sending. In this way, a requirement that “locations of spreading blocks of a plurality of users need to be aligned” can be satisfied, and no complex symbol is discarded, so that detection performance of the spreading blocks is ensured.
