  • Publication number: 20130244676
    Abstract: Examples are described relating to methods, apparatus and computer programs for configuring a user equipment in a cellular wireless network. Certain exemplary methods involve receiving (440), at the user equipment (430), control information regarding one or more of a plurality of channel-state information (CSI) reference signals. The plurality of CSI reference signals are receivable by the user equipment (430) from one or more of a plurality of antenna ports that form part of the cellular wireless network, the plurality of CSI reference signal being associated with corresponding antenna ports. The control information is for use in configuration of the user equipment (430) and is received over a radio communications downlink from a node (410) in the cellular wireless network. If estimation of one or more radio communication channels at the user equipment (430) is configured (450) based on the received control information, improvements in demodulation and CSI feedback are achieved.

  • Patent number: 8537037
    Abstract: There is determined an amount of available memory that is allocated for automatic repeat-request data. Then for each of a plurality of received data transmissions, an nth compression level is selected, in dependence at least in part on the amount of available memory, from among N possible compression levels for storing the respective received data transmission. In one specific embodiment each of the received data transmissions represents one HARQ process, and the nth compression level is selected from comparing an amount of memory needed to store the respective received data transmission and all other received data transmissions representing parallel HARQ processes as compressed according to the nth compression level against the determined amount of available memory. An algorithm iteratively checks the amount of memory needed for each of the N possible compression levels, from least compressed to most compressed in this specific embodiment.

  • Patent number: 8537684
    Abstract: A wireless transmitter transmits a plurality of data blocks defined in a transmission window for receipt by a receiver. The transmitter transmits a status request to the receiver for positive acknowledgement of successful receipt of the status request, the status request identifying a data block. The transmitter updates the transmission window upon receipt of a positive acknowledgement of receipt of a data block or upon receipt of a positive acknowledgement of receipt of a status request relating to a data block. The updating removes the record of the data block from the transmission window and adds a record of at least one different data block to the transmission window.

  • Patent number: 8532006
    Abstract: A new RRC Connected (mobility) state is described in which a UE utilizes a temporary identifier to monitor a downlink control channel in accordance with a discontinuous reception cycle; and maintains the new connected state, the discontinuous reception cycle and the temporary identifier while the UE re-selects to a second/serving access node which lies within a same designated reselection area as a first/source access node. In various specific embodiments, the DRX cycle is maintained but re-aligned with a system frame number of the second access node; the temporary identifier is a CRNTI and the designated re-selection area is defined by all contiguous cells in which respective access nodes broadcast the CRNTI in system information; the UE re-selects to the second access node in the absence of control signaling; and the UE enters the new connected mobility state automatically upon expiry of a time alignment timer or upon explicit network signaling while in a different connected state.

  • Patent number: 8526388
    Abstract: Mechanisms for controlling communications conducted in multiple frequency bands so as to decrease an interference level between the communications. When an interference situation caused between an UL communication performed on at least one frequency band and a DL communication performed on another frequency band is determined, a partial denial processing is conducted so as to deactivate a dedicated part of resource blocks used for the first communication on the at least one frequency band of the first communication in the case of an interference situation being determined. The first communication is then continued in parallel to the second communication, on the basis of resources different from the dedicated part of resource blocks deactivated in the partial denial processing.
