  • Patent number: 10742780
    Abstract: In generating a physical layer (PHY) data unit for transmission via a communication channel, information bits to be included in the PHY data unit are received. A number of padding bits are added to the information bits. The number of padding bits is determined based on respective virtual values of each of one or more encoding parameters. The information bits are parsed to a number of encoders and are encoded, using the number of encoders, to generate coded bits. The coded bits are padded such that padded coded bits correspond to respective true values of each of the one or more encoding parameters. The PHY data unit is generated to include the padded coded bits.

  • Patent number: 10659117
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may precode downlink signals to be transmitted to a user equipment (UE) using a precoding matrix. The precoding matrix may be selected by a UE from a number of precoding matrices (e.g., a codebook) and reported to the base station in a channel state information (CSI) report. As described herein, a base station may support techniques for limiting a number of precoding matrices that a UE may evaluate to identify a preferred precoding matrix to be indicated to the base station. In addition, the techniques described herein allow a base station to dynamically indicate an appropriate set of precoding matrices for the UE to evaluate based on the channel conditions at a given time.

  • Patent number: 9294219
    Abstract: Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a base station may transmit data to a relay station in a portion of a subframe instead of the entire subframe. The relay station may transmit control information during part of the subframe. The base station may transmit data to the relay station during the remaining part of the subframe. In another aspect, a target termination for a packet may be selected based on data and/or ACK transmission opportunities available for the packet. One or more transmissions of the packet may be sent with HARQ, and ACK information may be sent for the packet. The packet may be transmitted such that it can be terminated prior to the first subframe (i) not available for sending the packet or (ii) available for sending ACK information.

  • Patent number: 9250961
    Abstract: A SIMD processing unit processes a plurality of tasks which each include up to a predetermined maximum number of work items. The work items of a task are arranged for executing a common sequence of instructions on respective data items. The data items are arranged into blocks, with some of the blocks including at least one invalid data item. Work items which relate to invalid data items are invalid work items. The SIMD processing unit comprises a group of processing lanes configured to execute instructions of work items of a particular task over a plurality of processing cycles. A control module assembles work items into the tasks based on the validity of the work items, so that invalid work items of the particular task are temporally aligned across the processing lanes. In this way the number of wasted processing slots due to invalid work items may be reduced.

  • Patent number: 9055036
    Abstract: A first device initiates a handshake message exchange with a second device according to a security protocol. The first device determines that an application datagram is to be transmitted according to a first transport protocol that limits a size of a datagram based on a defined size. The first device also determines that an application datagram size is larger than the defined size. The first device fragments the application datagram if the application datagram size is larger than the defined size and secures the application datagram with the security protocol. The first device also encapsulates the application datagram fragments in handshake messages, wherein an encapsulated application datagram fragment is transmitted from the first device to the second device in a first security protocol record. The first device may also transmit, to the second device, another application datagram secured with the security protocol.
