Abstract: The present solution discloses a method and apparatus for controlling demodulation reference signal allocation of a user equipment by utilizing a cyclic shift subset determined for demodulation reference signal multiplexing orders supported by the user equipment. Within the cyclic shift subset, demodulation reference signal resources that cause the most significant interference to each other are identified, and cyclic shifts corresponding to the identified demodulation reference signal resources, are linked with as orthogonal complementary multiplexing resources as possible. If more than one cyclic shift subsets are determined for a demodulation reference signal multiplexing order, at least one cyclic shift subset is ignored for said demodulation reference signal multiplexing order.

A broadcast signal in which mobile service data and main service data are multiplexed is transmitted and received. Then, in a broadcasting receiver, the program table information including information about a service or a program of an ensemble is parsed according to an identifier of the ensemble in which the mobile service data are multiplexed, in the received broadcast signal. And a mobile service is outputted by using the mobile service data and the parsed program table information.

Abstract: A wireless local area network system establishes a PASSPOINT™ connection between a mobile station and a hotspot using an enhanced single SSID method or an enhanced dual SSID method. In the dual SSID method, an access point associates and authenticates a mobile device to a secondary SSID of the access point during enrollment and provisioning. After enrollment, the access point authenticates the mobile station to a primary SSID of the access point using the credential that the mobile station received from an online sign-up (“OSU”) server in connection with the secondary SSID. In the single SSID method, an access point performs two levels of authentication. During authentication, communications are limited to an 802.1x controlled port running on the mobile station and access point. After a first authentication, communications between the OSU server and the mobile station are unblocked. After the second authentication, all traffic from the mobile station is unblocked.

Abstract: A IEEE 802.11 Wireless Local Area Network (WLAN) system of an access point (AP) and one or more stations (STAs) reduces power consumption and increases battery life of power efficient low power STAs by decreasing the amount of time that a power efficient low power STA remains in an awake state. After indicating power efficient low power operation during association with an AP supporting such operation, the power efficient low power STA may enter the doze state from the time that the power efficient low power STA sends a PS-Poll until the power efficient low power STA receives the buffered DATA frame from the AP. While implementing the power efficient PS-Poll method, the AP can send the buffered DATA frame to the STA SIFS after the AP sends an ACK to the received PS-Poll from the STA.

Abstract: A wireless device is described that may selectively include resource allocation information in a frame to be transmitted to one or more other wireless devices. The resource allocation may indicate channel/sub-channel assignment for each wireless device. The wireless devices may each utilize this received resource allocation information to determine the appropriate segment/sub-band of the transmission that is intended for their receipt/consumption. A first signaling field (e.g., HE-SIG-A) may indicate whether the resource allocation information is present in a second signaling field (e.g., HE-SIG-B) of the frame. For example, a single bit may be toggled to indicate the presence of the second signaling field and therefore the presence of the resource allocation information. Alternatively, multiple bits may be used to indicate the length of the second signaling field (e.g., a length of zero indicates the absence of the second signaling field and accordingly the absence of the resource allocation information).

Abstract: A mobile data network supports making subscriber data addressable as devices in a mobile data network. Each data chunk is assigned a device address in the mobile data network. The data chunk can then be addressed as a device in the mobile data network. Data chunks corresponding to a subscriber are distributed across multiple devices in the mobile data network, which may include subscriber devices, network components in the mobile data network, and specialized devices provided by storage providers. The mobile data network is queried to determine related devices. An ad-hoc network of the related devices is formed. A data query by one of the related devices is sent to the related devices in the ad-hoc network to determine whether the data query can be satisfied by one of the related devices. If not, the data query is sent via normal channels in the mobile data network.

Abstract: A method and a device for forming a common transport datastream from several mobile-digital television signal datastreams and a common stationary-digital television signal datastream. A constant number of data units of respectively-constant size in every successive time interval with constant cycle duration for the transmission of every individual datastream is determined.

Data units of each of the datastreams of the mobile-digital television signal are transmitted in each case in associated, identical positions of at least one successive sequence, and define the individual positions of the data structure of the common datastream with data units of the respectively associated datastreams.

Abstract: One of the embodiments of the present invention relates to a method for rank adaptation at a base station. The method comprises performing, during a rank sounding time interval, data transmission for a user equipment by using a sounding rank. The sounding rank is different from a transmission rank that is used in a transmission time interval immediately prior to the rank sounding time interval. The method further comprises determining whether spectrum efficiency for the user equipment under the condition of using the sounding rank is better than spectrum efficiency under the condition of using the transmission rank; and adjusting, in response to a positive result obtained from the determining step, the transmission rank to the sounding rank so as to be used during a transmission time interval immediately next to the rank sounding time interval. The present invention also relates to corresponding base station device.

Abstract: A maintenance method for network connection and a computer system are provided. The method is adapted to a computer system having a real-time clock. The real-time clock is configured to regularly wake up the computer system to check whether a network connection is working normally. In the method, a wake up operation to wake up the computer system is received from a user. It is determined whether a connection time of maintaining the network connection so far from a last time of entering a power saving mode is greater than a counting time for the real-time clock to wake up the computer system. It is tested whether the network connection is working normally when the connection time is greater than the counting time. The counting time of the real-time clock is updated to the connection time when the network connection is working normally.
