Abstract: Format of a downlink control channel for a user equipment UE is changed in conjunction with switching the UE between being enabled for cross carrier scheduling and being disabled for cross carrier scheduling. The changed format is used on at least one serving cell of the UE's configured set of component carriers CCs. In one embodiment the changed format comprises an explicit carrier indicator field CIF for the case in which the switching is from disabled to enabled; and the changed format has no explicit CIF when the switching is from enabled to disabled. In another embodiment switching from disabled to enabled comprises the UE's configured set of CCs being changed from one to multiple cells; and switching from enabled to disabled comprises the UE's configured set of CCs being changed from multiple cells to one cell. In one embodiment the changed format is implicit.

Abstract: In a method for wireless communication, a receiver receives a first signal at a first radio frequency and determines the reception level of the first signal. The receiver receives data during a reception level of the first signal at the first radio frequency. The receiver decides, based on the determined reception level, whether at least one measurement is to be taken on a second signal transmitted at a second radio frequency. A radio station carries out the method.

Transmitting in a single sub-frame one or more physical reference signals for use in physical layer decoding of a physical channel in a plurality of sub-frames.

Abstract: Improved systems and techniques for controlling access to network resources. A base station broadcasts extended access barring (EAB) and access class barring (ACB) information. Upon a determination by a user equipment that the user equipment requires service from the base station, the user equipment determines its EAB category and call type. The user equipment receives the EAB and ACB information broadcast by the base station and determines if it is subject to EAB based on its EAB category. If the user equipment is not subject to EAB, the user equipment determines if its call type is subject to ACB and, if the call type is subject to ACB, applies access class barring based on its call type.

Abstract: An approach is provided for efficient signaling of redundancy version information. A redundancy version signaling module detects the start of a system information radio transmission window and assigns a redundancy version sequence at the start of the transmission window.

Abstract: An allocation of downlink resources is received, which are monitored on l layers for data. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of those resources is selected an algorithm from among a first algorithm that bundles them in a first mode and a second algorithm that bundles them in a second mode. The selected algorithm is used on the generated resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate l reply bits which are then transmitted. At the network side a NACK reply bit is received, based on a pattern of the allocated downlink resources, a first algorithm that bundles them in a first mode or a second algorithm that bundles them in a second mode is selected. A bundling window and layer combination are determined from the selected algorithm, which gives the resource for retransmitting the NACK'd data.

Abstract: A decoding method for decoding information content in at least one data packet, which is transmitted from a sender to a receiver via a data link. The information is represented by a bit sequence, which is transformed into a transmittable redundancy version. The information is initially transmitted for a first time in a first data packet from the sender to the receiver. The information is represented by a first redundancy version, which is self-decodable. An incorrect receipt is confirmed by sending a confirmation from the receiver to the sender. The information is retransmitted at least a second time in a second data packet from the sender to the receiver upon receipt of the confirmation, wherein, for representation of the information, a second redundancy version is used, the selection of which is performed in dependence on a coding parameter, describing whether the redundancy version is self-decodable or not.

Abstract: A user equipment receives from a network a transmitted (broadcast) access mode indicator that indicates whether a close subscriber group CSG network is being operated as open or close, and if it indicates open a user equipment UE that is not a registered member of the CSG is allowed access to the close subscriber group network as a guest member. The CSG network can provide higher priority services to its registered members by differentiating them over guest members by an indication, received from each UE in its RADIO RESOURCE CONTROL CONNECTION REQUEST message, whether it is registered or a guest. The CSG can also transmit its ID/name for display at the UE so the UE may select whether and which CSG to join.

Abstract: A rule specifies a timing relation between a measurement configuration which indicates at least one subframe to measure and a reporting configuration which indicates at least one subframe in which to report. This rule is used by both user equipment UE and network to map between a downlink subframe in which channel state information is measured and an uplink subframe in which the channel state information is reported. The network may configure the UE with the measurement and reporting configurations via dedicated signaling or broadcast. If the measurement configuration is periodic and indicates multiple downlink subframes to measure the rule results in a one to one mapping of downlink to uplink subframe where less than all of the multiple downlink subframes map to an uplink subframe; if aperiodic the rule indicates a single downlink subframe to measure.

Abstract: A mobile station operating in EGPRS mode needs to the early establishment of an uplink TBF although has not data to send, at the only precautionary purpose of preventing an intolerable latency negatively affecting the subsequent delay-sensitive transmissions. To this aim, the mobile sends a Packet Channel Request message in one phase access mode including a new establishment cause called “Early TBF establishment.” The network establishes an uplink TBF indicating the requester and assigns a radio resource on one PDCH channel or more. Then the network schedules the transmission from the mobile station also when it does not have data to transmit other than dummy packets. This is performed through the USF flags in the usual manner. As soon as actual data become available for transmission, the mobile send them instead of dummy packets. In an alternative embodiment the mobile sends the Packet Channel Request message in two phase access mode.

Abstract: An apparatus and a method are described by which a request for providing aperiodic channel information with respect to a selected downlink component carrier of a plurality of component carriers is received, the selected downlink component carrier is determined, channel information with respect to the selected downlink component carrier is established, and the channel information with respect to the selected downlink component carrier is sent.

Abstract: The invention relates to a method, terminal and network or entity wherein a broadcast service is used for informing a number of users on an emergency or other situation of public interest. A specific identifier is used in a paging message for activating broadcast service in the terminals. A terminal checks a received paging message with regard to the presence of the specific identifier and when detecting the specific identifier, switches to a broadcast mode for receiving broadcast content. The received broadcast emergency content is notified and/or displayed to the users of the terminals.
