摘要： The invention relates to devices and methods for signalling control information associated with transmission of data over a wireless channel. A second communication device receives (S2) data from a first communication device, wherein the data comprises an indication of recommended precoders and a recommendation of a first transmission rank to possibly use during transmission. The second communication device determines (S4) a second transmission rank to use for transmitting data, and transmits (S6) a confirmation message to the first communication device. The confirmation message comprises a confirmation that transmission of data from the second communication device is using at least parts of each recommended precoder associated with a frequency resource that falls within the transmission of data and an indicator of the second transmission rank to use.

摘要： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple- Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU- MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.

摘要： 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.

摘要： 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).
摘要翻译： 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）。
