  • Publication number: 20120020304
    Abstract: Example methods and apparatus to transmit uplink allocation indicators in wireless communications are disclosed. A disclosed example method involves sending a first assignment message indicative of first radio block periods assigned to the mobile station for downlink communications. At least one of the first assigned radio block periods is separated from a next occurring one of the first assigned radio block periods by at least a first non-assigned radio block period. In addition, the example method involves sending a second assignment message indicative of second radio block periods assigned to the mobile station for uplink communications. At least one of the second assigned radio block periods is separated from a next occurring one of the second assigned radio block periods by at least a second non-assigned radio block period.

  • Publication number: 20120020306
    Abstract: Example methods and apparatus to poll in wireless communications based on assignments are disclosed. A disclosed example method involves receiving a poll from a network during a first radio block period and identifying a resource for use in sending requested information to the network in response to the poll. The resource occurs during a subsequent radio block period, and the subsequent radio block period is separated from the first radio block period by at least one radio block period not assigned to the mobile station for transmission by the mobile station. The example method also involves transmitting a response to the poll.

  • Publication number: 20110201279
    Abstract: Methods and apparatus to perform measurements are disclosed. An example method disclosed herein for a user equipment (UE) to perform measurements in a mobile communication network comprises receiving configuration information comprising at least one of a validity state, a measurement activation criterion, a measurement deactivation criterion, a reporting criterion or a location request criterion to configure a measurement, and performing the measurement based on the configuration information.

  • Publication number: 20110134908
    Abstract: The present document relates to radio transmission. In particular, the present document relates to the single-slot dual transfer mode (DTM) available e.g. in GSM/GPRS/GERAN networks. A transmitter is described. The transmitter is configured to send circuit switched data over a traffic channel to a corresponding receiver, wherein the traffic channel is segmented into a plurality of frames. The transmitter if further configured to determine a vacant frame of the plurality of frames, wherein no circuit switched data is sent in the vacant frame due to discontinuous transmission; and to send packet switched data over the traffic channel using the vacant frame.

  • Publication number: 20110105158
    Abstract: Methods and apparatus to avoid transmission of redundant neighbor cell information to mobile stations. An example method to avoid transmission of at least some neighbor cell system information from a network to a mobile station disclosed herein comprises receiving neighbor cell system information, setting a validity indication representing whether the mobile station has valid neighbor cell system information associated with a neighbor cell, and sending the validity indication to the network.

  • Publication number: 20110105120
    Abstract: Methods and apparatus to monitor a channel to determine neighbor cell information are disclosed. An example method for a first mobile station to determine cell information for a first cell disclosed herein comprises monitoring a channel for messages containing cell information, receiving a first message via the monitored channel and addressed to a second mobile station, the first message including first cell information, and storing the first cell information for a time period after receiving the first message.

  • Publication number: 20110053595
    Abstract: An access procedure for call re-establishment is provided. In a first method, a mobile station, in at least some instances of detecting radio link failure, attempts call re-establishment on multiple cells concurrently. In a second method, a mobile station performs a first random access channel procedure when the mobile station is not aware of at least two cells with enabled call re-establishment, and performs a second random access channel procedure when the mobile station is aware of at least two cells with enabled call re-establishment.

  • Publication number: 20110053586
    Abstract: A radio link timeout procedure for call re-establishment is provided. A mobile station receives signals over a wireless link, determines whether there is a potential call re-establishment as defined by at least one condition, and decides whether radio link failure has occurred on the basis of the signals received over the wireless link such that while there is a potential for call re-establishment as defined by the at least one condition, a decision that a radio link failure has occurred is made earlier than if there is no potential for call re-establishment.
