1. A first device, comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the first device to:
receive, from a second device, a first configuration associated with an event to trigger transmission of a counting signal from the first device to the second device;
determine whether the event occurs; and
transmit, to the second device when the event occurs, at least the counting signal to enable the second device to count the number of devices for determining a type of signals,
wherein first device is caused to transmit, to the second device, an indication of a beam for a further transmission to be sent by the second device to the first device when the first device transmits the counting signal
wherein the event comprises detection of a triggering signal, and the first configuration indicates at least a starting time, a duration, and periodicity of a time interval for detecting the triggering signal,
wherein the type of signal is related to a unicast, multicast or broadcast service, and the triggering signal is associated with a radio network temporary identifier for identifying the unicast, multicast or broadcast service,
wherein the first device is further caused to:
receive, from the second device, a second configuration associated with the counting signal,
wherein the second configuration indicates one or more random access preambles and a time and frequency resource of a random access channel for transmission of the one or more random access preamble, and the counting signal comprises a random access preamble of the one or more random access preambles,
wherein the second configuration further indicates a common counting signal, and the first device is caused to generate the counting signal by adding a timing offset and a phase offset to the common counting signal, wherein the timing offset and the phase offset are implicitly determined, based on a device identifier, by the first device.
