Abstract: Embodiments of the present disclosure provide a resource allocation method, a packet communication method, and an apparatus. The resource allocation method includes: dividing, by a controller, a cloud data center network into multiple independent logical zones; allocating a corresponding tunnel label range to each logical zone; when a virtual network request for allocating a resource to a tenant is received, searching the logical zones to obtain a logical zone that meets the virtual network request; and allocating a tunnel label to the tenant according to a tunnel label range corresponding to the logical zone that meets the virtual network request. Because each logical zone is independent, during tunnel label range allocation, a same tunnel label range can be allocated to different logical zones. In this way, a same tunnel label can be allocated to different switches in different logical zones, implementing reuse of the tunnel label.

Abstract: A receiving device may remain in omni-directional mode while receiving RTS messages from transmitting devices. Multiple devices may transmit RTS messages at the same time, causing interference and preventing intended recipients of the RTS messages from transmitting a CTS message. To increase medium reuse, RTS may be transmitted and received in a slotted and directional manner. A receiving device may select a sweeping pattern for receiving transmission from neighboring devices. The receiving device may also determine one or more time slots allocated to each of the neighboring devices for receiving transmissions from the neighboring devices. The receiving device may transmit an indication of the sweeping pattern and the time slots to one or more of the neighboring devices. Subsequently, during one of the indicated time slots, the receiving device may perform a beam sweep to receive one or more RTS messages from one of the neighboring devices.

In this device, an extraction unit receives downlink data on multiple unit bands. A CRC unit detects errors in the downlink data. A response signal generation unit generates a response signal by using the results of error detection of the downlink data obtained by the CRC unit. The control unit arranges the response signal in the PUCCH resources corresponding to the current DL subframe.
