Abstract: Power control for devices having multiple transmit antennas are disclosed, including power control methods for Physical Uplink Control Channel (PUCCH) and Sounding Reference Signal (SRS) transmissions for a wireless transmit/receive unit (WTRU). The PUCCH and SRS power control methods include selecting a multiple input multiple output (MIMO) mode and changing the power of the PUCCH or SRS transmission based on the selected MIMO mode. Another power control method estimates an antenna gain imbalance (AGI) for a WTRU having at least two transmit antennas. The AGI is based on measuring a Reference Signal Received Power (RSRP) on each transmit antenna. Each transmit antenna is then scaled by an AGI scaling factor based on the estimated AGI.

Abstract: A method and apparatus are used in cooperative relays with incremental redundancy (IR) and distributed spatial multiplexing. A wireless transmit/receive unit (WTRU) may listen to the base station (BS) transmission during Phase 1 of the communication, and use cooperation between a relay station (RS) and the BS for the data transmission during Phase 2 to improve performance. During Phase 2, both the BS and the RS may transmit data to the WTRU, using either distributed Space Time Block Codes/Space Frequency Block Codes (STBC/SFBC) or distributed spatial multiplexing.

Abstract: Systems, methods, and instrumentalities are disclosed to provide feedback to a user equipment (UE). A UE may transmit uplink data via a supplementary cell. A network device, such as a HeNB, eNB, etc., may receive the uplink data from the UE via the supplementary cell.

Abstract: A method and apparatus for supporting communication via a relay node are disclosed. A relay node may receive wireless transmit/receive unit (WTRU) buffer status reports (BSRs) from a plurality of WTRUs that are served by the relay node. The WTRU BSRs indicate uplink buffer status at the WTRUs. The relay node then may forward the WTRU BSRs to a donor evolved Node B (DeNB). The relay node may send a relay node BSR to the DeNB. The relay node BSR indicates a relay node uplink buffer status and/or a relay node downlink buffer status at the relay node. The relay node may send a radio resource control (RRC) message to the DeNB for requesting radio resource reconfiguration.

Abstract: A method and apparatus for avoiding a collision. A collision may be avoided by allocating a first set of subframes to a backhaul link transmission, and allocating a second set of subframes to an access link transmission. In one example, the second set of subframes may be a non-overlapping set of subframes with respect to the first set of subframes. In a second embodiment, a collision may be avoided by receiving a data transmission from an evolved Node-B (eNB) and transmitting an uplink (UL) grant to a wireless transmit/receive unit (WTRU) and a first acknowledgement (ACK) to the eNB. The transmission may be in response to the received data transmission. The RN may avoid a collision by further transmitting an automatic ACK to the WTRU and transmitting a second UL grant to the WTRU. In a third embodiment, a collision between an access link transmission and a backhaul link transmission may be avoided by detecting a collision and determining an interface priority based on a collision occurrence type.

Abstract: A two-way paging system (100) includes one or more transmitters (106), a plurality of receivers (102), and at least one two-way personal pager (108). The pager (108) receives pages (110) from transmitter (106), and sends response signals (112) which are detected by receivers (102). Response signals (112) in the form of digital packets include forward error correction (FEC) encoding and digital symbols that each consists of a predetermined number of bits. The receivers (102) decode the response packets to verify their accuracy and to identify the symbols and can associate accuracy indicators with the detected symbols to provide an indication of the probability of accuracy. A microdiversity receiver (126) includes two receiver components (102) with separate antenna (122) at a single site. Signals (112) received by different components (102) are compared and the accuracy information combined to increase reliability. A central controller (116) receives, processes and analyzes information from several receivers (102) to determine the most likely response signals (112) sent by pager (108).

Abstract: Methods and apparatus for sounding reference signals (SRS) configuration and transmission. The methods include receiving configuration of wireless transmit/receive unit (WTRU) -specific SRS subframes for transmitting SRS and upon receipt of a trigger, transmitting the SRS for a number of antennas. The SRS transmissions may occur in each subframe of a duration of WTRU-specific SRS subframes that start a number of WTRU-specific SRS subframes after a triggering subframe. For multiple SRS transmissions from multiple antennas, cyclic shift multiplexing and different transmission combs may be used. The cyclic shift for an antenna may be determined from a cyclic shift reference value. The cyclic shift determined for each antenna providing a maximum distance between cyclic shifts for the antennas transmitting SRS in a same WTRU-specific subframe. SRS transmissions from multiple antennas in the WTRU-specific subframe may be done in parallel. Methods for handling collisions between SRS and physical channels are presented.
