Abstract: Methods, apparatus and computer program products are provided for rebalancing the sizes of downlink (DL) association sets for component carriers having different time division duplex subframes configurations. A method is provided that includes determining DL subframes that are included in a DL association set for each of a plurality of component carriers. In an instance in which the number of acknowledgement (ACK)/negative acknowledgement (NACK) bits corresponding to the DL subframes included in the DL association sets for respective component carriers differ by at least a predetermined amount, the method modifies the number of ACK/NACK bits corresponding to the DL subframes that are included in the DL association sets for each of the respective component carriers. The method may also cause transmission of the ACK/NACK bits in accordance with the DL association sets, as modified, via the respective component carriers. Corresponding apparatus and computer program products are also provided.
Abstract: A method for determining information about access barring includes the steps of: receiving a message set transmitted via a radio interface to a user equipment, the message set including at least a starting message that is a paging message; obtaining at least a first bit of a bit set from the starting message, wherein the bit set includes at least two bits and is intended for access barring; determining information of the bit set; the information at least disclosing whether the access barring is on or off; and receiving a system information block transmitted via the radio interface to the user equipment, the system information block comprising a scheduling information list that lists a further system information block that contains access barring parameters.

Abstract: A user equipment UE determines that a neighbor cell is higher priority than a serving cell, measures neighbor cell signal strength in n>1 iterations, and analyzes them for reselecting from the serving cell to the neighbor cell. Each measurement iteration is spaced from one another by a time interval (e.g., 1 DRX) that is specific for the neighbor cell being higher priority. In various embodiments, the UE measures while in a Cell-PCH, URA-PCH or idle state/mode and the first iteration is taken at the first available measurement opportunity after transitioning to that state/mode. The UE reselects to the neighbor cell based on the analyzed signal strengths; in one embodiment the decision to reselect is without regard to signal quality of the serving cell; and in another the decision is without regard to whether a reselection condition remains satisfied for a specified time period Treselection.

Abstract: A serving cell sends to user equipments (UEs) indications of frequency bands supported by neighbor cells/frequencies, at least one individual neighbor cell/frequency supporting a plurality of frequency bands. The neighbor cells/frequencies are filtered by the UE to retain only those that are indicated to support a frequency band or frequency bands which are also supported by the UE. The sent indications comprise, for each respective neighbor cell/frequency, one absolute radio frequency channel number (ARFCN) associated with the respective neighbor cell/frequency and the frequency band or bands associated with the respective neighbor cell/frequency. Examples are given of various system information blocks for sending the frequency band indications to the UE. In one embodiment they are arranged in an information element IE having an entry for each of the neighbor cells/frequencies and a list of frequency bands for each entry.
