Abstract
Embodiments of the disclosure generally relate to configuration of a random access preamble transmission. In response to receiving a handover request for handing over a terminal device from a source cell managed by a further network device to a target cell managed by the network device, a network device determines a configuration for a random access preamble transmission. The configuration indicates the number of times of transmission of the random access preamble from the terminal device. Afterwards, the network device transmits the configuration for the random access preamble transmission to the further network device.
Claims19
A method at a network device, comprising:
- in response to receiving a handover request for handing over a terminal device from a source cell managed by a further network device to a target cell managed by the network device, determining a configuration for a random access preamble transmission, the configuration indicating the number of times of transmission of the random access preamble from the terminal device;
- and
- transmitting the configuration for the random access preamble transmission to the further network device.
A network device, comprising:
- a processor;
- and
- a memory, the memory containing program including instructions executable by the processor, the processor being configured to cause the network device to:
- in response to receiving a handover request for handing over a terminal device from a source cell managed by a further network device to a target cell managed by the network device, determine a configuration for a random access preamble transmission, the configuration indicating the number of times of transmission of the random access preamble from the terminal device;
- and
- transmit the configuration for the random access preamble transmission to the further network device.
A terminal device, comprising:
- a processor;
- and
- a memory, the memory containing program including instructions executable by the processor, the processor being configured to cause the terminal device to:
- receive a configuration for a random access preamble transmission, the configuration indicating the number of times of transmission of the random access preamble from the terminal device, and the configuration being determined in response to a handover request for handing over the terminal device from a source cell to a target cell;
- and
- transmit the random access preamble for the indicated number of times to a network device managing the target cell in a random access procedure to the target cell.
