摘要： Operation of a network node in a mobile communication system that serves a User Equipment (UE) includes ascertaining whether the network node is operating in a broadcast-only mode. If so, then broadcast channel information is transmitted on a physical multicast/broadcast channel. Otherwise, the broadcast channel information is transmitted on a physical broadcast channel. To inform the UE of where to find the broadcast channel information, the network node transmits an indicator to the UE, wherein the indicator indicates whether the broadcast channel information is conveyed via the physical broadcast channel or the physical multicast/broadcast channel. The indicator can be included within signals that are also used to enable a UE's cell search procedure.

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 hybrid ARQ scheme is used incremental data packet combining. In an example embodiment, the hybrid ARQ scheme with incremental data packet combining employs three feedback signaling commands: ACK, NACK, and LOST. Using these three feedback commands, the hybrid ARQ scheme with incremental data packet combining provides both robustness and good performance. This scheme is particularly advantageous in communication systems with unreliable communication channels, e.g., a fading radio channel, where forward error correction (FEC) codes are used and some of the code symbols are more important than other code symbols. Benefits include increased throughput and decreased delay of the packet data communication.

摘要： A technique for operating a network node in a heterogeneously deployed network comprising network nodes of different nominal transmit powers and at least partially overlapping coverage areas is described. A method implementation of this technique comprises a step of operating the network node in a base mode in which the network node is configured to transmit terminal-specific demodulation reference signals for a first set of terminal devices. The method comprises the further step of selectively activating or deactivating operation of the network node in a Single Frequency Network (SFN) mode in which the network node is configured to transmit, for a second set of terminal devices, the same cell-specific reference nodes as another network node of the heterogeneously deployed network that has a larger nominal transmit power.

摘要： A radio network controller, RNC, 614, and a method therein, for enhancing reception quality of transmissions on an uplink control channel from a user equipment, UE, 613 to a serving base station, BS, 610. The RNC, the UE and the serving BS are comprised in a communication system 600. The method comprises, when conditions for boosting the uplink control channel are fulfilled, determining a boosting factor based on a ratio of path gains of a channel from the UE to the serving BS and of a channel from the UE to a non-serving BS 611, respectively, which non-serving BS is comprised in the communications system. The method further comprises transmitting the determined boosting factor to the UE, whereby the reception quality of transmission on the uplink control channel from the UE to the serving BS is enhanced by the UE boosting the control channel by means of the boosting factor.

摘要： In a heterogeneous 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, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node.

摘要： The present disclosure relates to a technique for transmitting modulation symbols on multiple frequency resources. A method aspect of this technique includes applying a Discrete Fourier Transform (DFT) coding per set of modulation symbols of two or more sets of modulation symbols, wherein a first set of modulation symbols from the two or more sets of modulation symbols is transmitted on a set of frequency resources handled by the same power amplifier. Then, Orthogonal Frequency Division Multiplexing (OFDM) modulation is applied to the sets of DFT coded modulation symbols to output a first set of OFDM symbols for transmission on the set of frequency resources, and output another set of OFDM symbols for transmission on at least one additional frequency resource distinct from the set of frequency resources. Power amplification is then applied per set of frequency resources at the power amplifier.

摘要： Mechanisms to provide independent DRX (discontinuous reception) functionalities for individual carriers of a multi-carrier wireless network (200) are described. DRX is a higher layer functionality indicating which TTIs (transmission time intervals) a user equipment (220) needs to read for control signals. Operating in the DRX cycle allows the user equipment (220) to reduce battery consumption. A connection is established between a base station (210) and the user equipment (220) over a plurality of carriers, where for each carrier, an independent DRX cycle is established. The plurality of carriers include anchor carriers which can carry commands from the base station (210). The anchor carriers have shorter DRX cycles than the non-anchor carriers. When a large amount of download data is to be transferred, the DRX cycles of multiple carriers are overridden and used for transfer to achieve fast download rates. The override commands are sent from the base station (210) to the user equipment (220) prior to the transfer.
