  • Publication number: 20110201367
    Abstract: A base station 1 includes a radio communication unit 11 and a frequency channel control unit 15. The radio communication unit 11 is capable of forming a primary cell and a secondary cell, and transmitting a physical channel for data transmission (HS-PDSCH) in each of these two cells. Further, the frequency channel control unit 15 determines a frequency channel available to the secondary cell based on the load status of a nearby cell formed by a nearby base station 7. In this way, the interference to the nearby cell caused by the base station 1 is suppressed.

  • Patent number: 7986956
    Abstract: Operation of a mobile voice client utilizing a WLAN for access is enhanced by controlling the rate at which transmission power is changed by the access point with which the mobile voice client is associated. The access point calculates a target transmit power level based at least in-part on the distance to the nearest fixed position wireless device and the distance to the mobile voice client. The access point then determines whether the target transmit power level differs from a current transmit power level. If the target transmit power level is greater than the current transmit power level, the current transmit power level is increased at a first controlled, non-instantaneous rate such as 1 dB per second. If the target transmit power level is less than the current transmit power level, the current transmit power level is decreased at a second controlled, non-instantaneous rate such as 1 dB per second.

The method includes: selecting any one of border nodes positioned at the edge of a cluster as a temporary cluster head as a temporary cluster head when a target is sensed in the cluster; bugging data of the temporary cluster head by border nodes in other adjacent cluster which do not sense the target to temporarily change the border node selected as the temporary cluster head to a cluster head of each of the border nodes; when the target is sensed by at least one of the border nodes, collecting data from each of the border nodes by the temporary cluster head to transferring the collected data to an actual cluster head of the temporary cluster head; and aggregating the collected data by actual cluster head of the temporary cluster head.

  • Publication number: 20110124359
    Abstract: A user terminal transmits a preamble signal generated using a Zadoff-Chu sequence. A correlation processing unit calculates autocorrelation of a received preamble signal. A preamble detection unit detects a side peak position of the autocorrelation of the preamble signal and calculates the main correlation value representing correlation at the main peak position and the side correlation value representing correlation at the side peak position. A frequency offset estimation unit estimates frequency offset that has occurred in the wireless transmission path according to the main correlation value and the side correlation value.

  • Publication number: 20110122833
    Abstract: Embodiments of a mobile station and a method performed by a base station for transmitting a paging message to an idle-mode mobile station are disclosed herein. In some embodiments, a multicarrier paging information (MC-PAG-Info) message is transmitted to indicate a time-slot and paging carrier for a subsequent transmission of a paging message to an idle-mode mobile station. The idle-mode mobile station may monitor the indicated paging carrier during the indicated time-slot of a paging listening interval for receipt of a paging message directed to the idle-mode mobile station. In some embodiments, the indicated time-slot and the paging carrier are determined by the idle-mode mobile station using a device identifier of the idle-mode mobile station and hash modulo parameters provided within the paging information message.

  • Patent number: 7949364
    Abstract: A system for managing the operation of a plurality of radio modems contained within the same WCD. One or more of the plurality of radio modems may be a dual-mode radio modem enabled to communicate using at least two separate radio protocols concurrently. The operation of the one or more dual-mode modems may be managed by resources encompassed in a radio modem interface coupled to, or integrated within, the dual-mode radio modem. These management resources may receive information from the operating system level of the WCD and from the at least two radio modem stacks utilizing the resources of the dual mode radio modem in order to coordinate the operation of the at least two radio protocols concurrently active in the modem.

  • Publication number: 20110117942
    Abstract: Method and arrangement in a base station, a user equipment and a positioning node, for sending, and obtaining, respectively, a value of a propagation delay of a signal. The signal is sent to the base station from a user equipment. The base station and the user equipment are comprised within a wireless communication system. Also, the base station and the user equipment are adapted to exchange wireless signals. The method is characterised by the step of receiving a signal sent from the user equipment. The method is further characterised by the step of measuring the value of the signal propagation delay of the received signal. Still further, the method is characterised by the step of sending the measured value to the equipment and/or to a positioning node comprised within the wireless communication system.
