Abstract: A clock determining method includes: when both a second network device and a first network device are synchronous with a reference clock, simulating, by using delay information between the second network device and the first network device and clock frequency information of the second network device, a second virtual clock synchronized with a first virtual clock, where the first virtual clock is used to simulate a clock of the first network device. A clock of the second network device can thus be simulated to perform a subsequent operation by using the simulated clock. For example, the simulated clock may be used to estimate precision time protocol (PTP) message synchronization performance of the second network device. Therefore, the PTP message synchronization performance of the second network device may be pre-determined before a global navigation satellite system (GNSS) fails, to guide network operation and maintenance activities.

Abstract: Embodiments of the present disclosure provide a communication method, a base station and a user equipment. The communication method includes: sending, by a base station, a random access response message to a user equipment UE, where the random access response message includes a timing advance command, and a value TA of the timing advance command is NTA/(N*Ts), where, the NTA indicates the amount of the time alignment the UE, the N*Ts indicates a unit granularity for the UE to perform time alignment, the N is greater than 16, and the Ts indicates the smallest time unit. In the present disclosure, the unit granularity for the UE to perform time alignment may be enlarged, so that the UE can use a larger amount of the time alignment when performing the time alignment, thereby supporting the coverage of a cell with a long distance.

Abstract translation: 本公开的实施例提供通信方法，基站和用户设备。 通信方法包括：由基站向用户设备UE发送随机接入响应消息，其中随机接入响应消息包括定时提前命令，并且定时提前命令的值TA为NTA /（N * Ts），其中，NTA表示UE的时间对齐量，N * Ts表示UE执行时间对准的单位粒度，N大于16，Ts表示最小时间单位。 在本公开中，可以扩大UE执行时间对准的单位粒度，使得在执行时间对准时，UE可以使用更大量的时间对准，从而支持长距离的小区的覆盖。

Abstract: A method for retransmitting data includes a transmitter receiving a retry request, where the retry request includes a sequence number of a first to-be-retransmitted flit. The transmitter reads data in a retry buffer based on the sequence number of the first to-be-retransmitted flit and retransmits the data, where the retry buffer includes flits of at least two types of data packets, and retransmission manners of the at least two types of data packets are different.

Abstract: A directory processing method and apparatus are provided to resolve a problem that a directory occupies a relatively large quantity of caches in an existing directory processing solution. The method includes: receiving, by a first data node, a first request sent by a second data node; searching for, by the first data node, a matched directory entry in a directory of the first data node based on tag information and index information in a first physical address; creating, when no matched directory entry is found, a first directory entry of the directory based on the first request, where the first directory entry includes the tag information, first indication information, first pointer information, and first status information, the first pointer information is used to indicate that data in the memory address corresponding to the indication bit that is set to valid is read by the second data node.
