Abstract: Methods, systems, and devices for wireless communication are described. A communication device may rewrite a TCP timestamp, delay sending of a TCP acknowledgement packet, or both, to reduce the likelihood that a TCP connection times out during a radio impairment event. The may establish a transmission control protocol (TCP) connection with a remote host via a first radio access technology (RAT). The communication device may determine a time stamp value associated with traffic of the TCP connection. The communication device may adjust the time stamp value in a TCP header based at least in part on a radio impairment event that is scheduled or predicted to occur within a defined amount of time. The communication device may also determine a duration of a delay and delay communicating a TCP acknowledgement packet over the TCP connection by at least the duration of the delay.

Abstract: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power “steps” that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.

Abstract: A method includes receiving, at a station, a first delivery traffic indication message (DTIM) assigned to a first delivery interval. The first DTIM is configured to indicate whether group-addressed traffic is scheduled for delivery during a beacon interval. The first delivery interval is larger than a second delivery interval associated with a second DTIM. The method further includes receiving the group-addressed traffic during the beacon interval.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A multi-radio device controls wireless communications by identifying one or more connection points between radio(s) of the multi-radio device and an operating system executing on a host device, analyzing a policy relating to the multi-radio device, and exposing, to the operating system, a subset of the connection points based on the policy. A modem manages a connection to an applications processor (AP) by virtualizing physical communication interfaces at the modem, providing a single Internet protocol (IP) interface representing the virtualized physical communication interfaces to a high level operating system (HLOS) at the AP, detecting a physical communication interface connected to the modem, and determining whether to expose the detected physical communication interface to the HLOS as a standalone virtualized physical communication interface, or hide the detected physical communication interface as part of an existing virtualized physical communication interface.

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: Methods, systems, and devices are described for determining a quality estimation of a wireless network that may be used to determine whether a particular wireless network meets one or more criteria for association with a station. The quality estimation may be based on a load quality of a basic service set (BSS) of an available wireless network and/or one or more wide area network (WAN) metrics associated with the wireless network. A station may evaluate such load quality and WAN metrics prior to association, and/or after association with a wireless network.

Abstract: Systems and methodologies are described that facilitate managing interaction between paging and discontinuous reception (DRX) cycles for users operating in a communication system. As described herein, a connected mode user having an associated DRX cycle can modify its schedule for paging reception to minimize unnecessary periods of activity. For example, a user can initially schedule monitoring of paging occasions that coincide with periods of activity associated with the DRX cycle of the user. If such paging occasions are not sufficient to reach a minimum required number of monitored paging occasions, additional paging occasions can be monitored as needed by scheduling additional periods of activity and/or extending periods of activity specified in the DRX cycle. Additionally or alternatively, a network can synchronize a connected mode DRX cycle associated with a user with an idle mode paging cycle for the user, thereby providing power and performance benefits with low complexity.
