Publication number: 20140092789Abstract: Various communication systems may benefit from techniques for handling inter-band carrier aggregation (CA). For example, systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) may benefit from a uplink (UL) downlink (DL) configuration zero handling, particularly in cases where there is no physical hybrid automatic repeat request (HARQ) indicator channel (PHICH). For example, certain embodiments may be applicable to inter-band CA having different UL/DL configuration in use. A method can include triggering in a downlink subframe a first physical uplink shared channel transmission in a first hybrid automatic repeat request process. The method can also include triggering in the downlink subframe a second physical uplink shared channel transmission in a second hybrid automatic repeat request process. The secondary cell can be configured with time division duplex uplink/downlink configuration number zero.Type: ApplicationFiled: September 27, 2013Publication date: April 3, 2014Applicant: NOKIA SOLUTIONS AND NETWORKS OYInventors: Hai Peng LEI, Li ZHANG, Chun Hai YAO

The user equipment (10) assumes that a default Channel State Information Reference Signal, CSI-RS, resource is co-located with a Demodulation Reference signal, DMRS, port when co-location is not explicitly signalled from the radio network node (12), wherein the default CSI-RS resource is configured by reading a predetermined entry in a configurable list of candidate co-location CSI-RS resources for a dynamic indication of co-location options in a Downlink Control Information, DCI, format. When assumed to be co-located, the user equipment (10) estimates one or more long term channel properties of the DMRS port and the default CSI-RS resource based on the assumption that the default CSI-RS resource is co-located with the DMRS port.Type: ApplicationFiled: May 31, 2013Publication date: April 3, 2014Inventors: George Jöngren, Stefano Sorrentino

Publication number: 20140092829Abstract: Methods, systems, and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) is configured to receive, in a first subframe, a physical downlink control channel or enhanced physical downlink control channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS) activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures, based on the SPS activation, a downlink (DL) assignment in a second subframe for receiving an SPS physical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. The UE determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE receives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation.Type: ApplicationFiled: June 27, 2013Publication date: April 3, 2014Inventors: SEUNGHEE HAN, YUAN ZHU, XIAOGANG CHEN, ALEXEI DAVYDOV, JONG-KAE FWU

In an example, a user equipment (UE) can include a processor configured to: Recursively attempt to decode the DCI from enhanced control channel elements (ECCE) of the EPDCCH from physical resource block (PRB) region candidates in a PRB set using a selected set of enhanced resource element group (EREG) index maps for the ECCE until the DCI is successfully decoded; and decode the DCI with an EREG index map associated with a same aggregation level used to encode the DCI. Each EREG index map can be configured for a different aggregation level (AL).Type: ApplicationFiled: June 28, 2013Publication date: April 3, 2014Inventors: Xiaogang Chen, Seunghee Han, Yuan Zhu, Qinghua Li, Jong-Kae Fwu

Publication number: 20140092831Abstract: CPU in a multi-wireless terminal, that allows simultaneous wireless communication for communication of a 1x system and communication of an LTE system, executes a process of monitoring a protocol state for the communication of the 1x system. When the protocol state for the communication of the 1x system is during transmission, the CPU executes a process of performing maximum value control for limiting a maximum value of transmission power for the communication of the LTE system. Moreover, when the protocol state for the communication of the 1x system is any state other than during the transmission, for example, during idle or during position registration operation, the CPU executes a process of stopping the maximum value control.Type: ApplicationFiled: July 10, 2013Publication date: April 3, 2014Inventor: Naritoshi SAITO

Publication number: 20140092835Abstract: A network controller as well as a method in a network controller for coordinating resource assignments to radio access points of a superdense, SDN, network is provided. The method comprises identifying a set of radio access points in the SDN network whose respective radio resource assignment is to be independently coordinated. The method also comprises obtaining interference information indicative of the extent to which radio transmissions to or from different radio access points in the set would interfere with one another absent radio resource assignment coordination. The method then forms subsets of the radio access points in the set based on this obtained interference information. The method also assigns different subsets of radio resources to the different subsets of the radio access points, and reports assignment information to the radio access points in the set, indicating the assignment of radio resources.Type: ApplicationFiled: September 26, 2013Publication date: April 3, 2014Applicant: Telefonaktiebolaget L M Ericsson (publ)Inventors: Fredrik Athley, Martin Johansson, Sven Petersson

Publication number: 20140092837Abstract: In a multi-carrier wireless system, potential problems from reconfiguring mobile station resources to accommodate changes in component-carrier configuration are mitigated by inserting a guard period each time the configuration of component carriers changes, so that transceiver reconfiguration can be carried out without interfering with ongoing transmission. A base station is configured to transmit data to a mobile station according to a first configuration of two or more component carriers, to determine that a change of configuration to a second component-carrier configuration is required, and to signal the change of configuration to the mobile station, using the first configuration of component carriers. The base station then refrains from transmitting data to the mobile station during a pre-determined guard interval of at least one transmission-time interval subsequent to the signaling of the change of configuration.Type: ApplicationFiled: October 1, 2013Publication date: April 3, 2014Inventors: Ghyslain Pelletier, Lars Sundström
