Abstract: A signal monitoring method and apparatus are provided. The method includes: determining, by a terminal device based on received configuration information, an index of a first time unit in which a start position of a control channel resource of a control channel is located, where a system frame number in which the first time unit is located is determined based on a first parameter; and monitoring, by the terminal device, the control channel starting from a time domain position corresponding to the index of the first time unit. In this way, the terminal device can monitor the control channel starting from a time unit corresponding to the index of the first time unit, to avoid monitoring the control channel extremely early and reduce overheads.

Abstract: This application provides an example communication method and apparatus. The communication method is performed in a communications system, where N antenna ports are configured for the terminal device, N is an integer greater than or equal to 2, the N antenna ports correspond to T antenna port combination modes, each antenna port combination mode corresponds to M antenna ports in the N antenna ports, and each antenna port combination mode set includes at least one antenna port combination mode. The communication method includes receiving, by the network device, first indication information from the terminal device, where the first indication information is used to indicate a first antenna port combination mode set. The method also includes determining, by the network device, K antenna ports in the N antenna ports based on the first antenna port combination mode set and sending, by the network device, second indication information to the terminal device.

Abstract: A memory access apparatus includes a read-write module and a processing module. The read-write module is configured to store an error detecting code in an (M+2)th DRAM in the memory row, and store the error correcting code in a Zth DRAM in the memory row, where Z is a positive integer, 1≦Z≦(M+1), and error correcting codes in consecutive (M+1) memory rows are stored in different DRAMs. The processing module is configured to calculate one group of error detecting code for each single chip burst cluster (SCBC) in a memory row, and calculate one group of error correcting code for all SCBCs in a memory row.
