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： Methods and apparatuses that facilitate power and quality control of uplink MIMO transmissions. A method in a NodeB comprises controlling transmission power of multiple pilot signals transmitted by a user equipment by using a single inner power control loop operating on at least one pilot signal of the multiple pilot signals. Some disclosed embodiments also relate to adjustment of a quality target applied by the single inner power control loop and to updating of a power offset for computing the number of bits that the user equipment can transmit on a stream that is associated with a pilot signal that is not power controlled by the single inner power control loop.

摘要： A NodeB (105) for an HSPA enabled WCDMA network (100), arranged (11, 12, 13) to transmit beam forming instructions to a User Equipment, a UE (110), which is arranged for beam forming. The beam forming instructions comprise information identifying a code book with one or more code words, and the NodeB is also arranged to transmit code words from said code book to the UE at a certain rate.

摘要： A user equipment transmits using at least two uplink transmit antennas and receives a set of control signals in the downlink direction from a cellular network. The user equipment estimates a received signal quality for each control signal in said set of control signals and determines, based on said received signal quality, which control signals have been reliably received. The user equipment derives one or more parameters related to the uplink transmit diversity operation using a subset of control signals from the set of control signals, said subset only including control signals determined as reliably received; and transmits in the uplink direction applying the derived one or more parameters to control the uplink transmit diversity operation. The accuracy of the transmit diversity parameter values derived/set by the UE can be improved. This will enhance the performance of the uplink transmit diversity and will also reduce interference to the neighbor cells.

摘要： Systems and methods related to a synchronization signal particularly well suited for wireless devices in an extended coverage area of a cell of a cellular communications network are disclosed. In one embodiment, a base station transmits a synchronization signal including multiple repetitions of a basic synchronization block during a coherence time of a downlink channel over which the synchronization signal is transmitted. The multiple repetitions of the basic synchronization block during the coherence time enable coherent combining during detection of the synchronization signal at wireless devices located in the cellular communications network. This coherent combining enables, for example, wireless devices located in an extended coverage area of a cell served by the base station to synchronize to the cell using a shorter synchronization signal than that which would be required if only non-coherent combining were used.

摘要： The present invention relates to methods and arrangements in a wireless communication system, and in particular to uplink outer loop power control. A Node B identifies if a UE from which the Node B receives data is in a predetermined set of power challenged situations. The Node B transmits to the RNC an indication to hold the SIR target of the UE if the UE has been identified to be in a power challenged situation. As a consequence, the uplink outer loop power control (OLPC) procedure in the RNC will not change the SIR target of the UE. This implies that the output power level of the UE remains unchanged as long as the UE remains in the power challenged situation. Thus, user and network performance are improved in the wireless communication system.
摘要翻译：本发明涉及无线通信系统中的方法和装置，特别涉及上行链路外环功率控制。节点B识别节点B从其接收数据的UE是否处于预定的功率挑战情况集合中。如果UE已被识别为处于功率受到挑战的情况，则节点B向RNC发送保持UE的SIR目标的指示。因此，RNC中的上行外环功率控制（OLPC）过程不会改变UE的SIR目标。这意味着只要UE保持在功率受到挑战的情况下，UE的输出功率电平保持不变。因此，无线通信系统中的用户和网络性能得到改善。
