This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for low-latency communications in wireless networks. In some implementations, a wireless station (STA) may transmit a data session request to a root access point (AP) in a wireless network responsive to activating an application associated with latency restricted (LR) data traffic. In some aspects, the data session request may indicate one or more preferred channels to carry the LR data traffic. In some other aspects, the data session request may indicate one or more preferred times to exchange the LR data traffic. In some implementations, the root AP may establish an LR data path with the STA based on the preferred time or frequency resources indicated in the data session request. The LR data path may include time or frequency resources that are reserved for LR data traffic between the root AP and the STA.

Wireless network configuration for low-latency applications

Methods and apparatuses are disclosed for communicating in a wireless communication network. One method of communicating over a wireless communication network includes transmitting, by a first wireless device, a connection capability request message to a second wireless device requesting connection capability information of the second wireless device. The method further includes receiving, by the first wireless device, a connection capability response from the second wireless device indicating one or more communication protocols available for providing a service to the first wireless device. In some aspects, the method may further include selecting, by the first wireless device, based at least in part on the connection capability response, a communication protocol from one of the one or more communication protocols indicated, wherein the communication protocol may be utilized for obtaining the service from the second wireless device.

Methods for connection capability exchange

In one example, a method includes performing, by a wireless dockee (WD), a plurality of operations to wirelessly dock with a wireless docking center (WDC) such that the WD may access one or more peripheral functions (PFs) associated with the WDC. In this example, the WD includes a docking service, an application service platform (ASP), and one or more peripheral services that each correspond to at least one PF of the one or more PFs associated with the WDC. In this example, the method also includes interfacing, by the docking service and with the ASP, to perform a first subset of the plurality of operations, and interfacing, by the docking service and with the one or more peripheral services, to perform a second subset of the plurality of operations.

Wireless docking architecture

In one example, a method includes determining, by a wireless dockee (WD), one or more wireless docking environments (WDNs) associated with a wireless docking center (WDC), wherein each WDN of the one or more WDNs corresponds to at least one peripheral function (PF) of one or more PFs that are each associated with the WDC. In this example, the method also includes wirelessly accessing, by the WD, a respective at least one PF corresponding to a particular WDN of the one or more WDNs associated with the WDC.

Utilization and configuration of wireless docking environments

In one example, a method includes receiving, by a wireless docking center (WDC) and from a wireless dockee (WD), a request to access one or more peripheral functions (PFs) associated with the WDC, and receiving, by the WDC and from the WD, one or more authentication credentials. In this example, the method also includes determining, by the WDC, whether or not the one or more authentication credentials received from the WD grant access to the one or more PFs to which the WD requests access. In this example, the method also includes permitting, by the WDC, the WD to access a first PF of the one or more PFs to which the WD requests access in response to determining that the one or more authentication credentials grant access to the first PF.

Access control for wireless docking

In one example, a method includes determining, by a wireless dockee (WD), one or more peripheral functions (PFs) associated with a wireless docking center (WDC). In this example, the method further includes establishing a docking session via a direct wireless connection between the WD and the WDC. In this example, the method further includes selecting, by the WD, at least one PF of the one or more PFs associated with the WDC. In this example, the method further includes accessing, by the WD, the at least one PF of the one or more PFs associated with the WDC.

Wireless docking

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.

Configurable host interface using multi-radio device and architecture for WLAN offload

A method includes establishing, by a wireless docking center, a secure wireless communication connection with a wireless dockee, receiving, by the wireless docking center, from the wireless dockee, an ASP session request for a wireless docking service of the wireless docking center, receiving, by the wireless docking center, from the wireless dockee, a passphrase for authenticating with the wireless docking service, determining, by the wireless docking center, whether the wireless dockee is authorized to access the wireless docking service based on the received passphrase, responsive to determining that the wireless dockee is not authorized to access the wireless docking service, denying, by the wireless docking center, the wireless dockee access to the wireless docking service, and responsive to determining that the wireless dockee is authorized to access the wireless docking service, granting, by the wireless docking center, the wireless dockee access to the wireless docking service.

Deploying wireless docking as a service

A wireless dockee device may include a memory, and at least one processor configured to authenticate the wireless dockee to a wireless docking service using a Wi-Fi direct service (WFDS) application service platform (ASP). A wireless docking center device may include a memory, and at least one processor configured to authenticate a wireless dockee to a wireless docking service of a wireless docking center using a Wi-Fi direct service (WFDS) application service platform (ASP).

Techniques are described for establishing a Wireless Serial Bus (WSB) service to transport data using a Media Agnostic Universal Serial Bus (MAUSB) protocol according to a selected transport mode in a WSB session of the WSB service. The MAUSB protocol may be deployed either over an Internet Protocol (IP) stack or directly over a Media Access Control (MAC) layer. According to the techniques, the wireless service advertiser and the wireless service seeker negotiate the transport mode for the MAUSB protocol in each WSB session of the WSB service. During a service discovery process, the wireless service advertiser identifies one or more supported transport modes for the MAUSB protocol in service information for the WSB service. During a P2P connection setup and a WSB session setup, the wireless service seeker indicates a selected one of the supported transport modes for the MAUSB protocol in session information for the WSB session.

An access point in a wireless communication system can be configured to include multiple virtual LANS (VLANs) based on security levels, thereby allowing secure traffic to be isolated from insecure traffic. Configuring the access point can include assigning a security level to each VLAN and setting a security association for each station associated with the access point. Based on this security association, each station can be assigned to an appropriate VLAN.

Method for organizing virtual networks while optimizing security

A key-caching system retrieves actively used keys from a relatively fast cache memory for fast processing of wireless communications. Additional keys are stored in relatively slow system memory that has high storage capacity. As keys become needed for active use, the keys are retrieved from the system memory and stored in the cache memory. By using active memory for keys actively being used, system performance is enhanced. By using system memory for keys not being used, a greater number of keys are available for transfer to the cache and subsequent active use.

Key caching system

A Hardware MAC (Media Access Control) unit implements time-critical functions according the 802.11 standard for telecommunications, thereby enhancing system performance. The MAC layer includes three sub-layers: MLME (MAC Sublayer Management Entity), which connects the MAC unit with the host CPU, FTM (Frame Transition Manager), which connects the MAC unit with the network, and FLPM (Frame Level Protocol Manager), which internally connects the MLME sub-layer with the FTM sub-layer. In particular, the FLPM manager includes time-critical and non-time-critical functions that are customarily implemented in software on the MAC by a MAC CPU (Central Processing Unit). The hardware MAC implements time-critical FLPM functions in hardware on the MAC and implements non-time-critical FLPM functions in software on the host CPU so that requirements for processing software on the MAC preferably may be altogether eliminated or alternatively may be substantially reduced.

Hardware MAC

A method of queue management includes: adding entries having a first priority to a first software queue; adding entries having a second priority to a second software queue; reading entries from the first software queue to a physical queue; at a threshold time, flushing entries from the physical queue; after the act of flushing the physical queue, reading entries from the second software queue to the physical queue until a termination criterion is satisfied; after the termination criterion is satisfied, reading entries from the first software queue to the physical queue; and transmitting entries from the physical queue to a network.

System and method for interleaving frames with different priorities

Systems and methods to provide ordered transmission of data packets to multiple destinations are presented. A transmission device includes a transmitter, a data packet ordering unit, a state table, and a transmit management interface such as a hardware/software unit. The state table stores a transmit block status of each destination. The transmit management interface is coupled to the transmitter and analyzes data packets. The transmit management interface determines whether to transmit a data packet targeted to a particular destination or to block transmission of data packets to the particular destination by examining the transmit block status of the particular destination from the state table.
