摘要: Techniques for performing frequency hopping in a wireless network are described. In an aspect, frequency hopping may be performed based on both cell identity (ID) and system time information. In one design, a user equipment (UE) may determine a cell ID of a cell and may obtain system time information for the cell. The UE may determine resources to use for transmission with frequency hopping based on the cell ID and the system time information. In one design, the UE may initialize a PN generator in each radio frame with an initial value determined based on the cell ID and a system frame number (SFN) for the radio frame. The UE may determine the resources to use for transmission based on a hopping function, a mirroring function, and a PN sequence from the PN generator. The UE may send a transmission on the resources to the cell.

摘要: Systems and methods provide a discovery protocol allowing nodes that are interested in knowing a network topology to discover other nodes in the network topology. The discovery protocol includes two message types, topology discovery messages and topology query messages. A node issues topology discovery messages upon powering up, at periodic intervals, or upon detecting a change in network topology. The topology discovery messages are broadcast to all nodes on a network and identify the issuing node to the network. A topology query message is sent to a particular node and requests a response from the receiving node regarding the neighboring nodes of the receiving node. The querying node can use the response data to discover other nodes and to send the discovered nodes query messages such that the node can determine a network topology to a desired level of depth within the network.
