    摘要: A method and apparatus for group owner (GO) renegotiation are provided. For example, the method and apparatus may be used for GO renegotiation in a wireless personal network (WPAN), for example, a 60-gigahertz (60 GHz) peer-to-peer (P2P) wireless network. The incumbent group owner (e.g., personal base station set (PBSS) control point (PCP)) controls the operation of the group. GO renegotiation can occur, for example, when a newly arriving device (e.g., a prospective group owner) is trying to connect to the PBSS and/or, for example, with PCP rearrangement among members of an existing group. As an example, after the formation of the group, the PCP may want to relinquish the role of being the PCP. A procedure is described for deciding among clients and the PCP which device will assume the role of group owner from the existing PCP in the event the role of group owner is to be reassigned.
