Abstract
Disclosed is a method comprising receiving, from a first transmission and reception point of a wireless communication network, an indication for transmitting a random-access preamble to a second transmission and reception point of the wireless communication network after a beam switch from a source beam of the first transmission and reception point to a target beam of the second transmission and reception point; and transmitting the random-access preamble to the second transmission and reception point after the beam switch.
Claims20
An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- receive, from a first transmission and reception point of a wireless communication network, an indication for transmitting a random-access preamble to a second transmission and reception point of the wireless communication network after a beam switch from a source beam of the first transmission and reception point to a target beam of the second transmission and reception point;
- and
- transmit the random-access preamble to the second transmission and reception point after the beam switch.
An apparatus comprising at least one processor, and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- transmit, to a terminal device, via a first transmission and reception point, an indication for transmitting a random-access preamble to a second transmission and reception point after a beam switch from a source beam of the first transmission and reception point to a target beam of the second transmission and reception point;
- and
- receive the random-access preamble from the terminal device via the second transmission and reception point.
