Apparatus and method of scheduling request transmission and reception

A method comprising:

• determining a scheduling request uplink control channel resource configured by higher layer for transmitting a scheduling request in a time interval;
• determining a first uplink control information for transmission in a first uplink control channel resource associated with a first identity in the same time interval;
• determining whether there is a second uplink control information in a second uplink control channel resource for transmission associated with a second identity in the same time interval;
• and
• controlling a transmitter to transmit, in the same time interval, one or a combination selected from:
• the first uplink control channel resource,
• the scheduling request uplink control channel resource, and
• the second uplink control channel resource.

A method comprising:

• receiving an uplink control channel resource carrying an uplink control information in a time interval;
• determining whether a scheduling request is expected to be transmitted by a remote device in the same time interval;
• and
• upon determination that the scheduling request is expected, decoding the uplink control channel resource to obtain information of the scheduling request.
