Patent
Qualcomm | Date: 2017-09-20

Methods and apparatus for multiple user uplink are provided. In one aspect, a method of wireless communication is provided. The method includes transmitting a quality of service (QoS) message to a device. The QoS message includes a request for a transmission opportunity for sending uplink data to the device. The QoS message includes at least one of a sequence control field or a QoS control field. The method further includes receiving a clear to transmit (CTX) message in response to the QoS message. The method further includes transmitting data to the device in response to the CTX message.


A method for ciphering and re-ordering packets in a wireless communication system, comprising ciphering input packets, at a first protocol layer, using a full sequence number as a crypto-sync to obtain ciphered packets; compressing, at a second protocol layer, the full sequence number to form a partial sequence number, wherein the partial sequence number comprises a less significant portion of the full sequence number and is used for over-the-air re-ordering; generating output packets from the ciphered packets, at the second protocol layer, the output packets appended with the partial sequence number, wherein the second protocol layer is a lower protocol layer in a wireless communication protocol than the first protocol layer; and transmitting the output packets over-the-air to a remote entity as well as a corresponding apparatus.

A method operative in a system utilizing a Request-to-Send/Clear-to-Send, RTS/CTS, protocol and that utilizes a plurality of channels for data transfer, comprising: sending, by a first device (100, 500), a first RTS frame over the plurality of channels, the first RTS frame including a first network allocation vector, NAV, set to a time duration that includes at least a second RTS frame and a second CTS frame; receiving, by the first device (100, 500), a first CTS frame from a second device (110, 500) based on receipt of the first RTS frame at the second device (110, 500), the first CTS frame being received over at least one of the plurality of channels; sending, by the first device (100, 500), a second RTS frame over the at least one of the plurality of channels based on receipt of the first CTS frame over the at least one of the plurality of channels, the second RTS frame including a second NAV, wherein each device (120, 130, 140, 500) within a network that receives the second RTS frame sets a NAV to a time duration that is based in part on information included in the second RTS frame; receiving, by the first device (100, 500) over the at least one of the plurality of channels, a second CTS frame output by the second device (110, 500) based on the second device (110, 500) receiving the second RTS frame; and transmitting, by the first device (100, 500), data to the second device (110, 500) within the time duration set by the second NAV using the at least one of the plurality of channels as well as a corresponding apparatus.


Embodiments disclosed herein relate to carrier allocation and management in multi-carrier communication systems. In some embodiments, the number of carriers assigned to an access terminal on a forward link may be determined by an access network, and the number of carriers assigned to the access terminal on a reverse link may be based on a cooperative process between the access terminal and the access network. In other embodiments, the number of carriers assigned to the access terminal on the reverse link may also be determined by the access network, e.g., in relation to the scheduling information received from the access terminal.

A method includes generating a command at a first microphone and sending the command from the first microphone to a second microphone. The command is sent to the second microphone via a bus that is coupled to the first microphone and to the second microphone.


Some aspects of the present disclosure provide for methods, apparatus, and computer software for low-power synchronization of wireless communication devices. In one example, an asynchronous code division multiple access (CDMA) channel may be utilized for uplink communication. By utilizing asynchronous CDMA on the uplink, synchronization requirements are relaxed relative to other forms of communication. Accordingly, a synchronization period after coming out of a sleep state can be short, reducing power consumption during re-synchronization. In another example, a low-power companion receiver, rather than the full-power WWAN receiver, may be utilized to acquire a sync signal while the device is in its sleep state. Once synchronism is achieved via the low-power companion receiver, the full-power radio may power up and perform communication with the network. By shifting the synchronization from the full-power radio to the low-power companion radio, power consumption during re-synchronization can be achieved.

A first computing device includes a memory, and at least one processor. The at least one processor may be configured to establish a wireless connection to a second computing device using a Wi-Fi Direct Application Services Platform (ASP), transmit data from a car connectivity consortium (CCC) Information Element (IE) to the second computing device, and establish a MirrorLink session using Universal Plug and Play (UPnP) to the second computing device via the wireless connection. The at least one processor may be further configured to establish a Wireless Serial Bus (WSB) session to the second computing device using the Wi-Fi Direct ASP via the wireless connection, and transmit data via the WSB session to the second computing device.


An integrated circuit is provided with an independent power framework for a first subsystem and another independent power framework for a processor subsystem that receives messages from the first subsystem.


Some aspects of the disclosure provide various methods, apparatuses and computer-readable medium configured for wireless communication. A method operable at a user equipment (UE) may include transmitting a connection request message configured to request initial connection with a radio access network (RAN) node. The connection request message may include information configured to indicate a service profile of the UE. A method operable at the RAN node may include receiving the connection request message from the UE. The connection request message may include information configured to indicate the service profile of the UE. A method operable at a serving node may include receiving a connection request message from the RAN node. The connection request message may be configured to establish communication with the UE and may include a service profile corresponding to the UE.


Systems and methods are disclosed for maintaining continuity of a peer-to-peer group session. The method may include exchanging a first P2P group session communication with a member of the P2P group via a direct data traffic connection, requesting session data from an application server, conveying the session data to a proxy UE, wherein the proxy UE is a member of the P2P group, and exchanging a second P2P group session communication with the application server in accordance with the session data.
