Abstract
Official abstract text for this publication.
A base station apparatus, configured to establish a wireless link for a backhaul line with a relay apparatus, and provide a first period in which a radio resource is used by the base station apparatus for the backhaul line, and a second period in which the radio resource is not used by the backhaul line.
First claim
Opening claim text (preview).
What is claimed is: 1. A first relay apparatus included in a wireless communication system that includes a control apparatus, the first relay apparatus and a second relay apparatus, the first relay apparatus comprising: one or more processors; and one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the first relay apparatus to: perform, using a first communication method, communication relay in at least a part of a communication link used for communication conducted by the control apparatus, wherein the second relay apparatus performs communication relay in at least another part of the communication link, and wherein the first relay apparatus performs communication relay in at least a part of a first link, included in the communication link, between the control apparatus and the second relay apparatus; and transmit, to the control apparatus and using a second communication method different from the first communication method, information indicating that disconnection of a part of a second link, included in the communication link, between the control apparatus and the first relay apparatus is detected. 2. The first relay apparatus according to claim 1 , wherein the first communication method is a method compliant with a fifth generation cellular communication standard, and the second communication method is a method compliant with a Long Term Evolution (LTE) standard. 3. The first relay apparatus according to claim 1 , wherein the first relay apparatus receives, using the second communication method, a signal instructing to reestablish a part of the communication link, of which the disconnection is detected. 4. The first relay apparatus according to claim 3 , wherein the first relay apparatus re-establishes, using the first communication method, connection on the part of communication link, of which the disconnection is detected based on the signal received from the control apparatus using the second communication method. 5. A communication method executed by a first relay apparatus included in a wireless communication system that includes a control apparatus, the first relay apparatus and a second relay apparatus, the communication method comprising: performing, using a first communication method, communication relay in at least a part of a communication link used for communication conducted by the control apparatus, wherein the second relay apparatus performs communication relay in at least another part of the communication link, and wherein the first relay apparatus performs communication relay in at least a part of a first link, included in the communication link, between the control apparatus and the second relay apparatus; and transmitting, to the control apparatus and using a second communication method different from the first communication method, information indicating that disconnection of a part of a second link, included in the communication link, between the control apparatus and the first relay apparatus is detected.
