Abstract: System, apparatus, and methods are provided for preventing the collision of physical cell identifiers. A network entity broadcasts via a first radio technology a physical cell identifier of a second radio technology, where the first and second radio technologies are co-located in the network entity. The network entity receives from a neighboring network entity another physical cell identifier of the second radio technology used by the neighboring network entity, where the neighboring network entity broadcasts the another physical cell identifier via the first radio technology, and where the first and second radio technologies are co-located in the neighboring network entity. The network entity changes the physical cell identifier, in response to the physical cell identifier being the same as the another physical cell identifier.

Abstract: Techniques for admitting user equipments (UEs) to wireless systems are disclosed. UEs may be assigned priorities for admission to a given wireless system. The UEs may then be admitted to the wireless system based on the priorities of the UEs for the wireless system. In one design, a UE may be identified for admission to a first wireless system among a plurality of wireless systems. Attributes (e.g., capabilities) of the UE for the plurality of wireless systems may be determined. An admission priority of the UE for the first wireless system may be determined based on the attributes of the UE for the plurality of wireless systems. Whether to admit the UE to the first wireless system may be determined based on the admission priority of the UE for the first wireless system and possibly the current resource usage of the first wireless system.

Abstract: A wireless terminal, when operating in a system including co-located access points (APs), may, to save scan power, only scan for a second wireless network when the received signal strength indicator (RSSI) from a first wireless network (WAN) is above or below a certain threshold. The AP from a first WAN may obtain the RSSI of a second WAN from terminals in the coverage of the second WAN, and compute the RSSI edge of the second WAN. This RSSI edge forms a threshold where terminals may start scanning for the edge of the second WAN. In addition, a second AP may only turn on and transmit a beacon when terminals exist within its range, determined by the second AP based on communications of co-located APs. Finally, the AP may provide hierarchical beacon messages to terminal monitoring of beacons on WANs when no information is being transmitted on those WANs.

Abstract translation: 当在来自第一无线网络（WAN）的接收信号强度指示符（RSSI）时，无线终端在包括共同接入点（AP）的系统中操作时可以节省扫描功率，仅扫描第二无线网络， 高于或低于某一阈值。 来自第一WAN的AP可以从第二WAN的覆盖范围内的终端获取第二WAN的RSSI，并计算第二WAN的RSSI边。 该RSSI边缘形成阈值，其中终端可以开始扫描第二WAN的边缘。 此外，当终端存在于其范围内时，第二AP可以仅打开并发送信标，由第二AP基于同位置AP的通信确定。 最后，当在这些WAN上没有发送信息时，AP可以向WAN上的信标的终端监控提供分级信标消息。
