  • Patent number: 8687541
    Abstract: The invention relates to methods for scheduling of uplink transmission and generating transport blocks according to multiple received uplink assignments Furthermore, the invention is also related to the implementation of these methods in hardware and software. To propose strategies for generating plural transport blocks within a given time constraint, the invention introduces prioritization of the uplink assignments, so that multiple uplink assignments can be ranked in the mobile terminal in a priority order. The prioritization of the uplink assignments is used to determine the order in which the individual transport blocks corresponding to the uplink assignments are filled, respectively how the data of different logical channels is multiplexed to the transport blocks for transmission in the uplink. Another aspect of the invention is to suggest joint logical channel procedures that operate on virtual transport blocks accumulated from the received uplink assignments.

  • Publication number: 20140029586
    Abstract: The invention relates to methods for reporting on downlink timings by a mobile terminal in a mobile communication system. In order to allow for an aggregation access point to obtain information on propagation delay differences of downlink transmissions on aggregated serving cells, the invention suggests the mobile terminal to report timing information based on reception time difference information for a the target/reference cell. The mobile terminal performs measurements relating to transmission and/or reception time differences on the target/reference cell, and reports same to the eNodeB. The eNodeB compares the measurement result to a predefined maximum propagation delay time difference. Alternatively, the mobile terminal performs the measurements, compares same to the predefined maximum propagation delay time difference and then report the comparison result to the eNodeB.

  • Publication number: 20140023010
    Abstract: The invention relates to a method for transmitting power headroom information from a user equipment to the base station. The transmission is made dependent on scheduling type of the uplink resource, for which the power headroom information is to be calculated and over which it is to be transmitted. If the uplink resource is dynamically scheduled, then the extended power headroom report according to Rel. 10 is transmitted; if it is scheduled persistently, e.g. as part of a semi-persistent scheduling configuration, then a basic power headroom report according to Rel. 8/9 is transmitted. The invention circumvents the problem of delaying data in persistently allocated uplink resources when transmitting an extended power headroom report.

  • Patent number: 8555126
    Abstract: The invention relates to a method for allocating radio resources to a mobile terminal for data transmission in a mobile communication system as performed by a mobile terminal and a base station, respectively. Moreover, the invention relates to a mobile terminal and a base station to perform such method, as well as an implementation of the method in software. The invention further provides a mobile communication system in which radio resources are allocated to a mobile terminal for uplink transmission. In order to avoid false activation of a semi-persistent resource allocation the invention defines new conditions under which a mobile terminal activates a semi-persistent resource allocation. Unlike for example in prior-art systems, a mobile terminal only activates a semi-persistent resource allocation, if it can confirm the activation command received from the access network. Preferably, the activation command and its confirmation are resource assignments.

  • Patent number: 8489953
    Abstract: The invention relates to a method for receiving data units when using one HARQ process of an HARQ protocol. The memory associated to the HARQ process is divided into several sub-areas, which are addressable by an identifier. Then, when data is received, same is stored in one of the sub-areas. By providing more than one sub-area for one HARQ process, it is possible to actually use one HARQ process for two (or more) different received data units, being from the same data flow or from a different data flow. The actual sub-area of the HARQ process for storing data units can be either freely selected at the receiving end or is indicated by an identifier associated with the data. Furthermore, persistent scheduled data is transmitted in units, scheduled at fixed time intervals. Thus, a control signaling field, usually used for indicating new units, can be used to store the identifier.
