摘要： The propagation time for propagation of a radio signal (93) from a radio transmitting station to a radio receiving station (91) is estimated based on calculated correlation values (102), calculated energy values (101) and a known energy value. The receiving station (91) receives a series of received signals (93) that respectively correspond to radio signaling bursts transmitted by the radio transmitting station. Each of the radio signaling bursts includes a known signaling sequence. The calculated correlation values (102) are indicative of correlations between the received signals and the known sequence, the calculated energy values (101) are calculated for the respective received signals, and the known energy value is the energy of the known sequence.

摘要： Acknowledgment signaling in a multiple carrier environment is enabled with a multiple carrier codebook having code words that jointly encode acknowledgment for at least two carriers. For an example embodiment, there is a method in a remote terminal for acknowledgment uplink signaling in a multiple-carrier mode. First, a code word is determined that jointly encodes acknowledgment signaling for at least two carriers from a multiple carrier codebook that is stored in the remote terminal. The multiple carrier codebook includes eight code words that are defined to have a single carrier codebook as a sub-codebook of the multiple carrier codebook, each code word of the eight code words having a length of ten. The multiple carrier codebook achieves a minimum Hamming distance of four among the eight code words. Second, an uplink signaling message that includes the determined code word is transmitted from the remote terminal to a wireless network node.

摘要： According to the teachings presented herein, a method and apparatus for communication signal processing advantageously use a mix of parametric and non-parametric correlation estimation in communication signal processing. Non-parametric estimation generates an "overall" correlation estimate for a received communication signal, and parametric estimation generates a "component" correlation estimate. The component correlation estimate is removed from the overall correlation estimate to form a partial correlation estimate that is used to process the received communication signal at least initially, such as in a pre-equalization stage. The overall and component correlation estimates are generated as impairment and/or data correlation estimates.

摘要： Method network nodes (110, 120) for enabling Outer-Loop Power Control "OLPC" performed by a control node (120) are disclosed. The control node (120) is configured to control a SIR-target for use by the radio network node (110) when operating an Inner Loop Power Control. The radio network node (110) receives a primary stream and a secondary stream while employing HSUPA MIMO. The radio network node (110) detects a first indication of number of HARQ re-transmissions. The first indication is related to the primary stream. The radio network node (110) detects a second indication of number of HARQ re-transmissions. The second indication is related to the secondary stream. The radio network node (110) configures an Iub frame based on one or more of the first and second indication. The control node (120) is configured to perform OLPC. Subsequently, the control node (120) receives the Iub frame from the radio network node (110) and extracts the first and/or second indication/s from the Iub frame. Next, the control node (120) determines (307) the SIR-target based on the first indication.

摘要： At least one transport data block is transmitted from a first sector of anetwork over a downlink to a wireless terminal during a time resource element for a multi-flow downlink transmission to the wireless terminal, and at least one transport data block is transmitted from a second sector of the network over a downlink to the wireless terminal during the time resource element for the multi-flow downlink transmission. A feedback message is received for the time resource element from the wireless terminal, wherein the feedback message includes a HARQ-ACK codeword selected from a HARQ-ACK codebook providing HARQ- ACK feedback for the at least one transport data block transmitted from the first sector and for the at least one transport data block transmitted from the second sector. The HARQ-ACK codeword is interpreted for the at least one transport data block transmitted from the first sector based on the first sector being a primary sector for the multi-flow downlink transmission.

摘要： A method in a network node for enhancing a channel estimate based on a Dedicated Physical Control Channel, DPCCH, between a user node and the network node is provided. The DPCCH has a first power. The network node receives (501) the DPCCH. The first power of the DPCCH is boosted with additional power, resulting in a second power. The network node then obtains (502) a channel estimate based on the DPCCH comprising the second power. As soon as said channel estimate is obtained, the network node removes (503) the additional power from the DPCCH based channel estimate.

摘要： Embodiments herein relate to a method in a network node (12,15) for managing transmit power of a user equipment (10) in a cellular network (1); wherein the network node (12,15) is comprised in the cellular network (1) and serves the user equipment (10). The network node (12,15) increases a power of a control channel of the user equipment (10). The network node (12,15) further limits a power increase of a data channel to a level by reducing a power of a serving grant of the user equipment (10) an amount, which amount corresponds to the increased power of the control channel. The network node (12,15) also reduces a reference value of the data channel for maintaining a transport block size of the data channel, which reference value determines mapping from the serving grant to the transport block size.
