Abstract: During uplink traffic, a map is formed between the MAC address and an upper layer identifier of each station of a communications network. When a downlink unicast packet is received, the identifier is compared to the map to select a corresponding MAC address. The packet having the selected MAC address is delivered to the station. During uplink, the MAC address of the station generating the packet is replaced with the MAC address of the relay receiving the packet. A device receiving an uplink multicast packet is assigned a temporary MAC address which remains valid during a known period. The device replaces the MAC address of the station generating the multicast packet with the temporary MAC address to generate a new packet that is transferred up the link. A downlink packet that includes the temporary MAC address and is received during the first time period is delivered as a response packet.

Abstract: Systems, methods, and devices for address format detection are described herein. In one aspect, a method of detecting whether an addressing format is supported by an access point on a wireless network is disclosed. The method includes transmitting a request to an access point using an addressing format including a source address field and a separate transmitter address field. In some aspects, the request may be an address resolution protocol (ARP) request or an Internet Control Message Protocol (ICMP) ping request. The request includes the source address field set to a first address and the transmitter address field set to a second address; monitoring transmissions of the access point to determine whether the access point transmits a response to the request that includes a destination address equal to the first address; and determining whether the access point supports the addressing format based on the monitoring.

Abstract: Techniques are provided for smooth transition between broadcast/multicast transmission and unicast transmission. A method for managing unicast and multicast services switching in a multi-band/multi-frequency wireless communications system (WCS) capable of both unicast and multicast signaling includes determining whether an aggregate demand for a content provided via dedicated unicast transmissions exceeds a threshold. The method includes switching transmission of the content from the dedicated unicast transmissions on one frequency to a multicast transmission on a second or more frequencies in response to determining that the aggregate demand exceeds the threshold.

Abstract: Techniques are provided for receiving one or more representations of content wirelessly. The method may involve receiving a media presentation description (MPD) that includes parameters for reception of data segments for multiple representations of content via broadcast transmission and unicast transmission. The method may involve determining whether the broadcast transmission or the unicast transmission is appropriate for reception of the data segments, and selecting a given representation from among the multiple representations of the content based on a criteria of the mobile entity. The method may involve receiving the data segments for the given representation based at least in part on the parameters for the determined one of the broadcast transmission and the unicast transmission.

Abstract: Access terminals are adapted to facilitate use of modified cell reselection parameters and/or procedures for access terminals exhibiting low or no mobility. An access terminal may employ one or more mobile thresholds to determine whether to perform cell reselection when the access terminal is mobile, and one or more stationary threshold to determine whether to perform cell reselection when the access terminal is stationary or substantially stationary. Methods operational on access terminals include determining the access terminal to be stationary or substantially stationary, and employing one or more stationary thresholds to determine whether to perform a cell reselection when the access terminal is determined to be at least substantially stationary. Other aspects, embodiments, and features are also included.
