    摘要: Embodiments of the present invention provide a method and an apparatus for determining reference signals. A User Equipment (UE) obtains group hopping information and/or sequence hopping information of a UE-specific reference signal from cell-specific system information broadcasted by an eNB. The UE receives UE-specific control information transmitted by the eNB to the UE. The UE generates a UE-specific reference signal of a first slot according to the group hopping information and/or sequence hopping information of the broadcasted cell-specific reference signal. If the UE-specific control information indicates that group hopping and/or sequence hopping of UE-specific reference signals is disabled, the UE generates a UE-specific reference signal of a second slot in a same frame with the first slot according to the UE-specific reference signal of the first slot. The UE is able to determine the reference signals when multiple UEs share physical resource blocks.

    摘要: A signal processing method in an MIMO multi-carrier system is disclosed comprising: receiving by a receiver signals of a plurality of sub-carriers transmitted from a transmitter; dividing the sub-carriers into a plurality of sub-carrier blocks according to the correlation between adjacent sub-carriers, each sub-carrier block containing K sub-carriers; selecting a feedback sub-carrier pre-coding matrix ( ) and a rotation matrix ( ) for each sub-carrier block, and then sending the information on the pre-coding matrix and the rotation matrix back to the transmitting end. The present invention provides the method and device for effectively settling the feedback problem in an MIMO/OFDMA system, thereby greatly reducing the number of pre-coding weight matrices needed to feed back to the transmitting device.

    摘要: A method and apparatus for transmitting an uplink Scheduling Request (SR) are provided. The method includes, obtaining a SR subframe configuration by receiving signaling, and transmitting SR information to a Base Station (BS) by using physical resources of another non-SR channel for transmitting other uplink control information. By applying the present invention, the SR, ACKnowledgement/Non-ACKnowledgement (ACK/NACK) or Channel Quality Indicator (CQI) information is returned to a BS when low Constant Modulus (CM) characteristic of an uplink Component Carrier (CC) is ensured.

    摘要: Embodiments of a User Equipment (UE) to operate in accordance with a physical random access channel (PRACH) are disclosed herein. The UE may comprise hardware processing circuitry to determine a coverage enhancement category for the UE based on downlink channel statistics related to reception of downlink signals at the UE from an Evolved Node-B (eNB) and an uplink-downlink imbalance parameter related to uplink reception at the eNB. The hardware processing circuitry may be further to select, for use in a coverage enhancement mode, a PRACH preamble from a set of candidate PRACH preambles based on the determined coverage enhancement category for the UE. In some embodiments, at least some of the candidate PRACH preambles may span a different number of sub-frames.
