Abstract: To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE.

Abstract: A method includes: A first node sends a first message on at least one broadcast frequency hopping channel, where the first message indicates a first resource on a first frequency hopping channel. The first node sends a second message on the first resource, where the second message indicates a second resource, and the second resource includes at least one third resource used to carry a request message. A second node receives the first message and the second message from the first node, selects a third resource from the at least one third resource, and sends a request message based on the third resource. The first node detects the request message on the at least one third resource.
