20150016389 | Simultaneous Reporting of ACK/NACK and Channel-State Information using PUCCH Format 3 Resources - A new uplink control channel capability is introduced to enable a mobile terminal to simultaneously report multiple packet receipt status bits and channel-condition bits. In an example embodiment implemented in a mobile terminal the mobile terminal (first determines that channel-state information and hybrid-ARQ ACK/NACK bits corresponding to a plurality of downlink subframes or a plurality of downlink carriers, or both, are scheduled for transmission in an uplink subframe. The mobile terminal then determines whether the number of the hybrid-ARQ ACK/NACK bits is less than or equal to a threshold number. If so, the mobile terminal transmits both the channel-state information and the hybrid-ARQ ACK/NACK bits in physical control channel resources of the first uplink subframe, on a single carrier. In some embodiments, the number of the hybrid-ARQ ACK/NACK bits considered in the previously summarized technique represents a number of ACK/NACK bits after ACK/NACK bundling | 01-15-2015 |
20150023311 | APPARATUS, SYSTEM, AND METHOD FOR SIGNALLING A QUANTITY OF ANTENNA PORTS IN A WIRELESS COMMUNICATION SYSTEM - A quantity of antenna ports of a transmitting apparatus is signalled in a wireless communication system. The quantity of antenna ports of the transmitting apparatus is encoded into a first type information and a second type information. The first type information is transmitted on a physical broadcast channel (PBCH); and the second type information is transmitted on a physical downlink shared channel (PDSCH). The PDSCH is transmitted on at least one antenna port indicated by the first type information. | 01-22-2015 |

20150071236 | User Equipment, Network Node and Methods Therein - A network node for demodulating uplink transmissions from a user equipment in a multiple cell communications network can be configured to receive uplink transmissions from the user equipment over a plurality of aggregated cells. The network node transmits, to the user equipment, determined timing advance information for uplink of one or more aggregated cells out of the plurality of aggregated cells. The network node receives, from the user equipment, an uplink transmission of at least one aggregated cell out of the plurality of aggregated cells. The network node then demodulates the received uplink transmission using weighted soft values in periods in the received uplink transmission. The periods are based on the transmitted timing advance information. | 03-12-2015 |
20150085955 | METHOD AND APPARATUS FOR TRANSMITTING PRECODING MARTRIX INDEX AND PREFORMING PRECODING - A method and an apparatus for sending a Precoding Matrix Index (PMI) and performing precoding are provided in the embodiments of the present invention. The method for sending the PMI comprises the following steps: a user equipment acquires the transmission channel capability of carrying the PMI; according to the transmission channel capability of carrying the PMI, the precoding matrices are selected from a locally-stored first codebook set to form a second codebook set; a first precoding matrix is selected from the second codebook set; an index corresponding to the first precoding matrix is sent to a base station over the transmission channel so as to make the base station can find out the first precoding matrix according to the index and precode the data according to the first precoding matrix. The embodiments of the present invention can realize the flexible configuration and use of the PMI. | 03-26-2015 |
