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： Introduction of discontinuous transmission in CDMA communications techniques is achieved by selectively using additional spreading codes for spreading a frame of data. By dividing a frame into two or more portions and spreading each portion with a different spreading code, the frame can be transmitted in a compressed mode wherein the information is transmitted during a portion of the frame period, leaving an idle part of the frame in which to perform other functions, such as evaluation of other frequencies for use in handover between frequencies.

摘要： Methods and arrangements for autonomous handover are provided. In a step, a mobile terminal sends a measurement report to a first network node. In another step, the mobile terminal starts a timer for measuring a wait period. In a further step, the mobile terminal waits until the wait period has expired. In still another step, the mobile terminal measures a signal used for mobility evaluations from the first radio network node. In yet another step, the mobile terminal performs random access to the second radio network node, if appropriate. Furthermore, the first radio network node sends information about random access channel (RACH) characteristics. Moreover, the first radio network node may send the wait period to the mobile terminal. In another step, the first radio network node sends the terminal context to neighbouring radio network nodes.

摘要： In one embodiment, a method of transmitting system information on a down link shared channel structured as successive subframes includes transmitting (400-416) system information in regularly occurring time windows, each time window spanning some number of successive subframes. The method further includes indicating (406/408) to receiving user equipment (120) which subframes within a given time window carry system information. The method and variations of it are applied, for example, to the transmission of dynamic system information on the down link shared channel or other down link channel in a 3GPP E-UTRA wireless communication network (100).

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： Method and apparatus for avoiding or reducing interference between transmissions from a donor eNB to a relay node and down link transmissions from the relay node to at least one mobile terminal, where the transmissions take place in overlapping frequency bands. In the method, at least one interruption is created in a transmission from the relay node to the mobile terminal (s), and during the created interruption, a transmission from the donor eNB is received. This may result in an improved reception of the transmission from the eNB in the relay node.
