摘要： Channel-state information and hybrid-ARQ ACK/NACK information for multiple carriers are simultaneously transmitted using a PUCCH Format 3 structure, where the hybrid-ARQ ACK/NACK bits and CSI bits are separately encoded and interleaved. In an example method, a power control offset parameter is calculated (2110) as a linear combination of at least a number N, representing a number of channel-state information bits and a number M, representing a number of hybrid-ARQ ACK/NACK bits. The method continues with the calculating (2120) of a power level for a transmission on a physical uplink control channel (PUCCH), using the power control offset parameter. In some embodiments, encoded channel-state information and hybrid- ARQ ACK/NACK bits are then transmitted (2060) according to the calculated power level. In some embodiments, the linear combination is of the form aN + bM + c, where a, b, and c are non-zero constants.

摘要： In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.

摘要： Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-overlapping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particular region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.

摘要： Some embodiments provide a method for transmitting a downlink control channel in at least one block of resources. The downlink control channel comprises a set of resource element groups. The method may be executed by a transmitting node, e.g., an eNB. The transmitting node first determines whether to transmit the downlink control channel using localized or distributed transmission. Responsive to determining to use localized transmission, the transmitting node performs the transmission such that all resource element groups in the set that are comprised in the same block of resources are mapped to the same antenna port, and the antenna port depends on which subset of resource element groups in the block of resources are used for the downlink control channel.

摘要： A network node in a wireless communication network communicates an enhanced Physical Downlink Control Channel (ePDCCH) to a user equipment (UE). This begins with the transmission, to the UE, of a configuration message that indicates the mappings of eDPCCH onto resource elements for both a first eDPCCH set and a second eDPCCH set. The mapping for the first eDPCCH set avoids the use of resource elements already in use by a first type of signal (e.g., a Cell-Specific Reference Signal or CRS), whereas the mapping for the second eDPCCH set avoids the use of resource elements in use by a second type of signal. The choice of an eDPCCH set for transmitting data to a UE may then be dynamically made in order to avoid interference caused by the first or second types of signal.

摘要： Techniques for supporting both localized and frequency-distributed control channel messages in the same enhanced control channel region are disclosed. An example method begins with receiving (2010) a downlink signal comprising an enhanced control region consisting of at least two sets of physical resource block (PRB) pairs. The method continues with the forming (2020) of one or more distributed enhanced control-channel elements (eCCEs) from a first set of PRB pairs by aggregating physical layer building blocks from multiple PRB pairs to form each distributed eCCE. One or more localized eCCEs are formed (2030) from a second set of PRB pairs by aggregating physical layer building blocks such that each of the localized eCCEs is formed from physical layer building blocks from within a single PRB pair of the second set. Control channel message candidates are formed (2050) from the distributed eCCEs and localized eCCEs, respectively, and decoded (2060).

摘要： Example embodiments presented herein are directed towards a base station (401), and corresponding method, for scheduling a downlink broadcast transmission using PDSCH. The base station (401) is also configured to provide an OFDM PDSCH to a wireless terminal (505A) which monitors ePDCCH for receiving downlink control data. Thus, by applying such a symbol, a wireless terminal (505A) which monitors ePDCCH and a wireless terminal (505B) which monitors PDCCH may receive the same downlink broadcast transmission on PDSCH. Example embodiments are also directed towards a wireless terminal (505A) for receiving such downlink broadcast transmissions.

摘要： The scheduling flexibility of CSI reference signals enables time and frequency synchronization using multiple non-zero CSI-RSs transmitted in the same subframe, or using CSI-RSs transmitted in the same subframe with other synchronization signals. Also, multiple synchronization signals may be scheduled in the same subframe to enable fine time and frequency synchronization without cell-specific reference signals.
