Thu, 27 Oct 2016 08:00:00 EDT

A method is provided for receiving an Enhanced Physical Downlink Control Channel (EPDCCH) from a base station by a user equipment (UE) in a wireless communication system. An EPDCCH is received for a first carrier by monitoring first EPDCCH candidates for the first carrier in a specific physical resource block (PRB) pair set. An EPDCCH is received for a second carrier by monitoring second EPDCCH candidates for the second carrier in the specific PRB pair set. The first EPDCCH between each of the first EPDCCH candidates at a specific aggregation level. The second EPDCCH candidates have an offset smaller than the interval from the first EPDCCH candidates.



METHOD AND DEVICE FOR RECEIVING OR TRANSMITTING DOWNLINK CONTROL SIGNAL IN WIRELESS COMMUNICATION SYSTEM

Thu, 27 Oct 2016 08:00:00 EDT

A method and a user equipment (UE) for receiving a downlink control signal in a wireless communication system are discussed. The method according to an embedment includes determining a minimum aggregation level for a plurality of enhanced physical downlink control channel (EPDCCH) candidates. The minimum aggregation level is 2 if both a downlink (DL) bandwidth includes at least 25 resource blocks (RBs) and a downlink control information (DCI) format is one of DCI formats 2, 2A, 2B, 2C and 2D. The method further includes monitoring the plurality of EPDCCH candidates in an EPDCCH set to decode an EPDCCH transmitted from a base station (BS) using the minimum aggregation level; and receiving a physical downlink shared channel (PDSCH) corresponding to the decoded EPDCCH.



GENERATING AND TRANSMITTING DEMODULATION REFERENCE SIGNALS

Thu, 27 Oct 2016 08:00:00 EDT

The present disclosure provides a solution which solves the problem of demodulation reference signal (DMRS) ambiguity by introducing separate, i.e. different DMRSs. This is especially the case for systems employing dynamic allocation of control and data signals to different PRBs.



MULTI-USER COMMUNICATION IN WIRELESS NETWORKS

Thu, 27 Oct 2016 08:00:00 EDT

An Access Point (AP) performs a Multi-User (MU) transmission by allocating a plurality of resources of an Up-Link (UL) MU transmission to a first plurality of stations, and by transmitting, using one or more 20 MHz channels, a Down-Link (DL) PHY Layer Convergence Procedure (PLCP) Protocol Data Unit (PPDU). The DL PPDU includes trigger information. The trigger information solicits the first plurality of stations to participate in the UL MU transmission using the allocated resources. All of the allocated resources may be in the one or more 20 MHz channels of the DL PPDU. The allocated resources may include at least one resource in each of the one or more 20 MHz channels of the DL PPDU.



METHODS FOR INTER-SYSTEM CARRIER AGGREGATION IN ADVANCED WIRELESS COMMUNICATION SYSTEMS

Thu, 27 Oct 2016 08:00:00 EDT

There is provided a signalling method for use in an advanced wireless communication network (100) that supports a first duplex mode, a second duplex mode different to the first duplex mode, and carrier aggregation of the first second duplex modes. This method includes configuring a UE (104-106) for data communication with the network (100) through a first access node (101) as a PCell, on the first duplex mode and with a first transmission mode (TM) including one or more transport blocks (TBs). This method also includes configuring the UE (104-106) for data communication with the network (100) through a second access node (103) as a SCell, on the second duplex mode and with a second TM including one or more TBs. The second TM associated with the second access node (103) is configured independently of the first TM associated with the first access node (101).
