Provided are methods and devices for updating a virtual desktop, where, when receiving a first scrolling command, a server calculates a first offset corresponding to the received first scrolling command, and sends the calculated first offset and a first scrolling direction contained in the received first scrolling command to a thin client, where the server detects whether the server receives a second scrolling command within a preset time, and when the server does not receive the second scrolling command within the preset time, the server calculates first emerging pixel information according to a first image which is cached this time and an image which is sent to the thin client last time, and sends the calculated first emerging pixel information to the thin client.

The present disclosure relates to a method of receiving, by a station that operates in a wireless LAN system, a signal in a wireless communication system. In this case, it is possible to include the steps of receiving a PPDU that includes an MAC frame, decoding the MAC frame, and checking information in the MAC frame based on the MAC header of the MAC frame that includes a first address field and a second address field. In this case, when the PPDU includes the identification information (ID) of a station, the MAC header may include only one of any of the first address field and the second address field.

A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords c.sub.i, where i is a unique codeword index for each codeword c.sub.i. Each codeword defines weighting factors to apply to the MIMO signals, and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets S.sub.i for each codeword c.sub.i of the codebook C. Each codeword subset S.sub.i defines L codewords c.sub.j, which are selected from all the codewords c.sub.i in the codebook C. The codewords c.sub.j in a codeword subset S.sub.i are the L codewords in the entire codebook that best correlate with the corresponding codeword c.sub.i.

The invention relates to a method and an arrangement for reducing the amount of messages sent in a communication network comprising a first communication network entity, a second communication network entity connected to said first communication network entity over a communication interface and one or more user equipments connected to said second communication network entity over a radio interface, whereby messages are sent on said interfaces using at least a first and a second protocol. General rules are provided for sending first protocol messages packed inside second protocol messages, so called “piggybacking”, and each first protocol message is provided with an instruction field defining a co-ordination of procedure steps to be taken for performing an action.

The current document is directed to a multi-stage metric-data compression method and subsystem for compressing metric data collected and stored within distributed computing systems to facilitate computer-system management and administration. In a described implementation, metric data is partitioned into constant metric data, low-variability metric data, and high-variability metric data. High-variability metric data is compressed by identifying a set of basis metrics, or independent metrics, with respect to which a remaining set of dependent metrics can be expressed using coefficient multipliers. The high-variability metric data can then be stored as a set of independent metrics and set of coefficients, along with a small amount of additional data.

Methods and apparatus, including computer program products, are provided for communications. In one aspect there is provided a method. The method may include sending, by a gateway, an advertisement including an internet protocol version 6 over low power wireless personal area network context option carrying a well-known prefix, the well-known prefix indicating to a node that the gateway provides an uplink in accordance with internet protocol version 4; and receiving, at the gateway, a first packet received via the wireless network in accordance with internet protocol version 6, the first packet including a destination address in accordance with internet protocol version 4. Related apparatus, systems, methods, and articles are also described.

One embodiment includes a system. The system includes a receiver configured to extract a timestamp from a header of each packet of a data stream received from a network and to de-packetize the data stream to provide a stream of data blocks. The timestamp can correspond to generation of each data block associated with each respective packet of the data stream according to a global timebase. The system also includes a delay controller configured to measure a delay associated with each packet of the data stream based on the timestamp relative to the global timebase and to control converting the data stream to a corresponding analog output signal for transmission based on the measured delay.

Systems and methods for managing pod cells using a global repository cell (GRC), as well as providing cloud-based storage to the pod cells and the GRC, are described. In some embodiments, the cloud-based storage enables an enterprise, or multiple enterprises to sync the operations between a master cell (e.g. the GRC) and one or more pod cells. For example, when there is no network connectivity between the GRC and its pod cells (e.g., the GRC and the pod cells are part of different enterprises or otherwise not under a common enterprise or organization), the cloud-based storage may act as an intermediate storage device or system between the GRC and its associated pod cells.

Various communication systems may benefit from improved bandwidth compression techniques. For example, certain communication systems may benefit from a radio fronthaul traffic compression on a frequency domain data. A method can include identifying a composite waveform corresponding to a real component and an imaginary component of a frequency domain data at a first device. The method may also include causing a transmission of a value that represents the composite waveform to a second device from the first device.

A method for enabling applications to compress and un-compress selected objects based on defined rules is provided. The method may include generating un-compressed objects and proxy objects, and storing the generated un-compressed objects on an un-compressed objects storage. The method may include receiving defined rules. The method may include compressing the stored un-compressed objects based on the defined rules, and storing the generated compressed objects on a compressed objects storage. The method may include receiving requests to invoke methods. The method may include in response to a determination that the received requests are to invoke methods associated with the un-compressed objects, retrieving the stored un-compressed objects. The method may include in response to a determination that the received requests are to invoke methods associated with the stored compressed objects, retrieving the compressed objects. The method may include restoring the retrieved compressed objects. The method may include presenting the invoked methods.
