摘要： The present invention discloses a method in a wireless access network node for controlling a UE. The UE comprises at least two transmit antennas, and is capable of uplink transmit diversity. There is an antenna weight associated with each transmit antenna. First, the wireless access network node determines that the antenna weights of the user equipment may be controlled. Then, it creates a control signal that comprises control information and transmits it to the user equipment. The control information controls a UE autonomous selection of the antenna weights in the UE.

摘要： Techniques are disclosed for signaling retransmission-related information in a multi-carrier wireless communication system supporting three or more carriers. In an example method, a wireless transceiver forms a first ACK/NACK groupby jointly coding ACK bits and NACK bits for a first subset of the carriers, and transmits the first ACK/NACK group during a first transmission slot allocated for the first ACK/NACK group. If no carriers of a second subset of the carriers are activated for the wireless transceiver, then the first ACK/NACK group is also transmitted during a second transmission slot that is otherwise allocated to ACK/NACK information for a second subset of the carriers. In another method, first and second ACK/NACK groups corresponding to first and second subsets of carriers are each formed from a codebook comprising a DTX codeword indicating that no data transmission for the mobile station was detected for the corresponding subset of carriers.

摘要： User equipment (1100, 1200) supporting multi-carrier operation is adapted to identify whether it is experiencing an excessive interference level on a downlink carrier, which interference may be due to an aggressor carrier. Based on this information, the user equipment deactivates one or more of the downlink carriers so that an adequate downlink quality can be maintained for at least some of the carriers. In an example method, a plurality of activated downlink carriers including at least two non-adjacent downlink carriers in a frequency band are received (1010). The user equipment monitors (1020) quality of at least a subset of the plurality of activated downlink carriers, and determines (1030) that the quality of at least one of the monitored carriers is worse than a predetermined threshold. In response, the user equipment deactivates (1040) one or more of the activated downlink carriers.

摘要： In a network (500) that provides high-speed packet access, a mobile terminal (510) is served by multiple activated serving cells (520) which are grouped into cell groups. The mobile terminal monitors control channel transmissions to detect whether there are any transmissions for the mobile terminal from the activated serving cells for each cell group and provides feedback to a primary serving cell. When no transmission is detected from serving cells of a particular cell group, the mobile terminal may transmit feedback information explicitly indicating that no transmission is detected for that cell group. Alternatively, the mobile terminal may withhold transmitting feedback for that cell group and increases the power for transmitting the feedback information for cell groups in which transmissions were detected.

摘要： The disclosure relates to methods and apparatuses that facilitate power and quality control of uplink MIMO transmissions. A method in a NodeB comprises controlling (50) 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 (60) of a quality target applied by the single inner power control loop and to updating (71, 72) 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： The disclosure relates to methods and apparatuses that allow for channelisation code allocation adapted for uplink MIMO transmissions. A method for use in a user equipment of a telecommunication system comprises spreading data symbols of a plurality of streams to be transmitted from the user equipment as MIMO transmissions. The step of spreading the data symbols comprises allocating, for each stream, at least one channelisation code (62) to be applied for spreading the data symbols of the stream. The plurality of streams are allocated channelisation codes (62) from a predefined code tree (61) of applicable channelisation codes such that any channelisation code (62) is allocated to more than one stream only if there is no applicable channelisation code left in the code tree (61) which currently is not allocated for any stream. The channelisation code allocation scheme makes it possible to avoid inter- stream interference in many scenarios of uplink MIMO transmissions.

摘要： In a method and a system for managing resources in a cellular radio system comprising an Enhanced Dedicated Channel, the release of the common E-DCH resources is signaled between UE and NodeB using existing signaling fields on Layer 2 (L2) or Layer 1 (Ll). These signaling fields are already in use in CELL_DCH, but their interpretation is changed for users in CELL FACH. In another embodiment, a grant on E-AGCH indicating INACTIVE on all HARQ processes is sent as a release command to the UE. In still another embodiment, the common E-DCH resource is released upon expiry of a release timer.

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).
