Abstract: A method includes receiving, at a first station of a peer-to-peer infrastructure-less network, a data packet transmitted from a second station of the peer-to-peer infrastructure-less network. The method also includes determining whether to retransmit the data packet to at least one other station in the peer-to-peer infrastructure-less network or whether to suppress retransmission of the data packet based on received signal strengths of received retransmissions of the same data packets from one or more nearby stations.

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: Methods and devices for communicating in a communication system are described herein. In one aspect, methods and devices for group based access control of machine to machine devices for wireless communication are described. One method includes forming a machine-to-machine (M2M) group identifier based on a M2M service category. The method further includes associating the M2M group identifier with at least one wireless device. The method further includes transmitting data intended for receipt by the M2M group, the data including the M2M group identifier.

Abstract: Systems and methods for communicating in a wireless communication system are described. Various processes for reducing the initial link set up time are described. In one aspect a method in a wireless communication system is provided. The method includes receiving, at a terminal, a message including information for establishing a link with a device in the wireless communication system. The method further includes identifying, at the terminal, a time slot and a back-off amount within the identified time slot based on a value included in the received message. The method also includes abstaining from sensing a medium based on the identified time slot and the identified back-off amount. The method further includes transmitting an association request message to establish the link with the device during the identified time slot after expiration of the back-off amount.

Abstract: Methods and apparatuses are provided that pausing transmission control protocol (TCP) transmissions during or following handover to prevent unwarranted duplicated acknowledgement transmission, which can cause decrease in TCP window size. During handover, transmission on-hold commands can be sent to a TCP layer that indicate to prepare to pause TCP transmissions, immediately pause TCP transmissions, and/or the like (1004). Transmission resume commands can be sent to the TCP layer following handover. In addition, TCP transmissions can be paused following handover to allow data forwarding data to be provisioned to a device from a target base station without duplicated acknowledgement transmission (1304).

Abstract: Radio access interworking technologies allow a target network to notify a source network that a mobile device has moved from source network to target network, wherein mobile device does not need to perform notification to source network. Further, source network can provide a first subset of overhead information to mobile device and, after moving to target network, mobile device can receive a second subset of overhead information from target network. Further, mobile device can perform prehashing prior to moving to target network based on a channel list received from source network.
