Abstract: The present invention relates to methods and arrangements for assisting a User Equipment (UE) to determine transmit power to be used on a first uplink component carrier y, wherein the base station is configured to communicate with the UE over a plurality of uplink and downlink component carriers x,y. The UE is aware of path loss parameters associated with a second downlink component carrier x. The method in a base station comprises determining cell specific path loss parameters associated with the component carriers of the base station. The cell specific path loss parameters at least comprises path loss parameters associated with the first uplink component carrier y and a second uplink component carrier x which is paired to the second downlink component carrier x, wherein the second uplink component carrier and second downlink component carrier are within one frequency band. The method comprises the further steps of calculating a pathloss offset, deltaPL(y,x), for the first uplink component carrier y, wherein the pathloss offset deltaPL(y,x) is the pathloss power offset for the first uplink component carrier y with respect to the second uplink component carrier x, and sending the calculated pathloss offset, deltaPL(y,x) to the UE.

Abstract: The present invention relates to methods and arrangements that make it possible to control the delay for the UEs to access the EUL resources in the Enhanced Uplink in CELL_FACH state procedure, independently from the delay for the UEs to access 5 ordinary UL resources in the RACH procedure. This is achieved by a solution where the timing of entering (or re-entering) a transmission procedure for Enhanced Uplink in CELL-FACH state is controlled with the help of a transmission control parameter defined specifically for this transmission procedure, instead of using the same parameter as for the RACH procedure.

Abstract: A network node (28) communicates over a radio interface (32) with a wireless terminal (30). Both the network node (28) and the wireless terminal (30) have multiple-input multiple-output (MIMO) capabilities. A MIMO-related order (90) is generated for inclusion in control signaling on a high speed downlink shared channel from the network node (28) to the wireless terminal (30). The MIMO-related order (90) is configured to modify channel quality indication (CQI) communications between the wireless terminal (30) and the base station (28) in view of MIMO capabilities of the wireless terminal (30). The method further comprises providing a channel quality indication (CQI) report (92) the wireless terminal (30) to the base station (28) in accordance with the order.

Abstract: A Level-1 (L1 ) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH - that is, Part 1 bit encodings that are not defined in the UTRAN specifications - and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to "ping" a UE (18).

Abstract translation: Level-1（L1）信令标志被映射到HS-SCCH的第1部分中的未使用（无效）比特序列 - 即未在UTRAN规范中定义的第1部分比特编码 - 并且对应的L1命令被编码 这允许UE（18）提前检测到HS-SCCH是纯粹的L1信令，并且UE（18）可以通过不处理伴随的HS-PDSCH来避免浪费功率。 或者，在无CPC HS-SCCH模式中，UE（18）可盲解码HS PDSCH。 在一个实施例中，通过L1信令来定义和控制通用DRX模式。 在一个实施例中，UE（18）确认提高了L1信令准确度。 在一个实施例中，利用L1信号和UE（18）确认协议来“ping”UE（18）。

Abstract: When a high SIR can be achieved for downlink data transmission, for example in a MIMO system, or when higher order modulation, such as 64 QAM, can be used, it is desired to measure the instantaneous downlink channel quality indicator (CQI), and report the measured CQI to the network using the same number of bits as when a lower SIR can be achieved. In order to do this, a true CQI is derived based upon at least one network controlled parameter and a measured channel quality parameter; and the true CQI value is scaled to a new CQI value such that the new CQI will fall within a specified range of CQI values; so that the new CQI achieved by scaling the derived CQI value can be reported with every CQI value over the entire reporting range requiring the same number of bits.

Abstract translation: 当可以实现用于下行链路数据传输的高SIR时，例如在MIMO系统中，或者当可以使用诸如64QAM的高阶调制时，期望测量瞬时下行链路信道质量指示符（CQI），并且 使用与可以实现较低SIR相同数量的比特将测量的CQI报告给网络。 为了做到这一点，基于至少一个网络控制参数和测量的信道质量参数导出真实的CQI; 并且将真实CQI值缩放到新的CQI值，使得新的CQI将落入CQI值的指定范围内; 使得通过缩放导出的CQI值实现的新CQI可以在需要相同位数的整个报告范围内的每个CQI值被报告。

Abstract: 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.
