摘要： A high-power point (110) and one or more low-power points (120) transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point, so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110). A low-power point (120) measures timing or frequency, or both, of one or more signals received at the low-power point (120) from the high-power point (110), and adjusts the timing or frequency, or both, of a transmission from the low-power point (120) to a mobile station (130), to align the transmission with signals received by the mobile station (130) from the high-power point (110).

摘要： The technology disclosed provides the ability for a subframe to be configured as a "flexible" subframe. As a result, at least three different types of sub frames in a TDD system may be configured: a downlink ("DL") subframe, an uplink ("UL") subframe, and a "flexible" subframe. While the DL and UL subframes are preconfigured for each frame instance, the flexible subframes are dynamically allocated to be an uplink subframe in one instance of a frame and a downlink subframe in another instance of the frame.

摘要： Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore 'UP' transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.

摘要： The present invention provides a method, a radio base station (40) and a mobile terminal (50) for allocating resources in a telecommunications network, where communications between the radio base station (40) and the mobile terminal (50) take place over a plurality of carriers. The method comprises transmitting and receiving a resource allocation message comprising one or more bits. Each of the bits corresponds to a number of resource blocks, where the number is determined from the ratio of the aggregate bandwidth of the plurality of carriers divided by the bandwidth of the carrier over which the resource allocation message is sent.

摘要： A network informs a user equipment about the number of usable sub-carriers in a frequency spectrum. Based on this, and its knowledge of a generic size of a resource block, the user equipment is able to determine a number of sub-carriers that are to be allocated to one or more fractional resource blocks. Rules, which may be predefined in the standard, or may be signalled to the user equipment, allow the user equipment to determine which of the usable sub-carriers should be allocated to the fractional resource block or blocks.

摘要： A communication unit (10, 20, 40) and a method for communicating at least one signal over a channel of a first channel type and at least one signal over a channel of a second channel type, which is different from the first channel type. The apparatus comprises a timer (19, 30, 50) adapted to schedule a predetermined time period, during which interference due to simultaneous communication of signals over the channel of the first channel type and the channel of the second channel type is anticipated. Also, the apparatus comprises a processing unit (16, 29, 49) adapted to apply, during the predetermined time period, an interference counteracting process for counteracting interference between any signal communicated over the channel of the first channel type and any signal communicated over the channel of the second channel type. The interference counteracting process comprises changing, during the predetermined time period, from a first to a second format for representing information transmitted over the channel of the first channel type, the second format being more robust than the first format.

摘要： In a heterogeneous network cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, relevant data (e.g. control information) transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node (i.e. simultaneously to the macro node during the same protected transmission time intervals).
