| 摘要 | A method for determining a presence of a relay node in a wireless communications system. The method includes receiving, from a network node in the system, information indicating the presence of at least one of an access node and the relay node. The method further includes determining whether the network node is the one of the access node and the relay node based on the information. | ||

| 主权项 | 1. A method for determining a presence of a relay node in a wireless communications system, wherein the relay node is configured to wirelessly communicate with an access node in the system, the method comprising: receiving, by a user agent in the system, information indicating the presence of at least one of the access node and the relay node from a network node in the system, wherein the user agent is not a relay node; and determining, by the user agent, whether the network node is the access node or the relay node, based on the information, wherein the information comprises a list of node identifiers for at least one relay node in a cell covered by the access node, and wherein the list is included in a connection-setup message sent to the user agent by the access node upon the user agent sending a random access message to the access node. | ||
