Abstract:
The present invention discloses a method for indicating pilot state, a radio network controller. The method includes: acquiring, by an RNC, state information of a scheduled non-precoded pilot, where the state information of the scheduled non-precoded pilot indicates activated state or deactivated state of the scheduled non-precoded pilot; and sending, by the RNC, 4Tx MIMO mode configuration signaling to a UE, where the configuration signaling carries the state information of the scheduled non-precoded pilot, so that the UE acquires state of the scheduled non-precoded pilot according to the state information of the scheduled non-precoded pilot when being configured to 4Tx MIMO mode. The method for indicating pilot state and the radio network controller according to embodiments of the present invention can reduce physical-layer signaling overheads and reduce a delay in acquiring state of a scheduled non-precoded pilot by the UE in 4Tx MIMO mode.

One example method includes that at least one data packet of a first service is received, where the at least one data packet includes a first data packet, and the first data packet is located at a first location in the at least one data packet. Then, the at least one data packet and first indication information are sent to a first network device, where the first indication information indicates the first location.
Abstract:
A random access method and apparatus are provided. The method includes: a terminal device obtains a position of the terminal device and a position of a network device, the terminal device determines a time adjustment value based on the position of the terminal device and the position of the network device, and the terminal device sends a random access preamble based on the time adjustment value and a random access channel (RACH) resource configured by the network device. Based on this solution, the terminal device may determine the time adjustment value based on the position of the terminal device and the position of the network device, and adjust a time for sending the random access preamble on the RACH resource. This helps avoid a problem that random access preamble receiving time windows overlap, thereby increasing a success rate of accessing the network device by the terminal device.

Abstract:
A data transmission method includes: A first access network device receives a first paging message from a core network device, where the first paging message includes a first security parameter. The first access network device sends a second paging message to a terminal device, where the second paging message includes a first random access preamble index that is ciphered and/or integrity protected by using the first security parameter. The first access network device receives a first random access preamble from the terminal device, and if the first random access preamble is a random access preamble indicated by the first random access preamble index, obtains downlink data of the terminal device. The first access network device sends the downlink data to the terminal device.
