  • Patent number: 9045513
    Abstract: A method for preparing a precursor used to label hepatocyte receptors is revealed. The precursor contains a bifunctional structure including trisaccharide and DTPA ligand. During synthesis processes of the precursor, silica gel columns and Reverse phase-18 (RP-18) columns are used for purification. Thus both the purification times and cost of each purification are reduced. Moreover, use diethyl ether to facilitate precipitation of products and remove a part of coupling reagent. Removing the coupling reagent helps purification of products. Furthermore, N?,N?-bis(carboxymethyl)-L-lysine hydrate and benzyl chloroformate are coupled to form a trisaccharide skeleton so as to ensure the yield rate of trisaccharide structure.

  • Publication number: 20150119098
    Abstract: A power control method to mitigate in-device coexistence (IDC) interference is provided. A wireless communication device (UE) is equipped with a first LTE radio module and a second co-located WiFi/BT/GSNN radio module. Upon detecting coexistence or IDC interference, the UE applies power control method to mitigate the interference. In a first embodiment, the LTE radio module adjusts its power parameters locally without informing the serving eNB. In a second embodiment, the LTE radio module adjusts its power parameters and implicit informs the eNB through existing PHR reporting. In a third embodiment, the LTE radio module changes its power or power class and explicitly informs the eNB through UE capability or new RRC message or MAC CE. Power control can be used as a low cost and lightweight solution before applying other heavyweight solutions that either require more resource or control overhead, or have higher impact on throughput.

  • Patent number: 8964658
    Abstract: A method for contention-based (CB) uplink transmission in a wireless communication network is provided. A base station (eNB) first transmits CB configuration information and CB grant to a user equipment (UE). The UE derives a plurality of transmission opportunities from the uplink CB grant and in response transmits uplink CB data via one of the transmission opportunities. The UE then receives an acknowledgment from the serving base station. If the uplink CB data is non-decodable by the eNB due to multiple contention UEs, then the UE retransmits the uplink data in response to a negative acknowledgment. In one novel aspect, the uplink transmission radio resource carriers both the uplink CB data and UE-selected signature information. In one embodiment, the UE-selected signature information is transmitted via pilot tones. By eliminating a separate phase of contention resolution, the overall latency of CB transmission is reduced and transmission efficiency is improved.

  • Publication number: 20140362811
    Abstract: Sounding mechanism for LTE-A systems under carrier aggregation is provided. A UE receives an uplink or downlink grant transmitted from an eNB over a primary carrier in a multi-carrier LTE-A system. The UE determines indicated carrier(s) and detects a triggering condition for aperiodic sounding transmission in the grant. The UE then selects UE-specific sounding reference signal (SRS) parameters. Finally, the UE transmits an aperiodic SRS (ap-SRS) over the indicated carrier(s) using the selected UE-specific SRS parameters. In one embodiment, the uplink or downlink grant is transmitted via a PDCCH carrying various DCI formats. Each DCI format contains a carrier indicator field (CIF) that indicates which carrier is used for ap-SRS transmission if cross-carrier scheduling is enabled. In another embodiment, DCI format 3/3A is transmitted via a PDCCH carrying a plurality of information fields, each field indicates if the UE should enable ap-SRS in a particular carrier.

  • Publication number: 20140341065
    Abstract: A method of determining priority rules for periodic CSI reporting in carrier aggregation is proposed. A UE obtains channel state information (CSI) feedback for multiple downlink component carriers (CCs) in a multi-carrier wireless communication network. Each downlink CC is associated with a feedback mode, and each feedback mode comprises a set of feedback types to be reported to a base station at time slots configured by an upper layer. The UE then determines a prioritized downlink CC for CSI reporting based on priority levels of the feedback types to be transmitted for each downlink CC at a given time slot. The UE then transmits the corresponding CSI feedback for the prioritized downlink CC at the given time slot via a feedback channel over a primary uplink CC. In one embodiment, different feedback types are prioritized by groups, and each group has several feedback types sharing the same priority.

  • Publication number: 20140341167
    Abstract: A method of multi-set RRC signaling for ap-SRS configuration is provided to enhance ap-SRS flexibility. An eNB transmits a plurality of sets of UE-specific SRS parameters to a UE via upper layer messaging in a multi-carrier wireless communication system.

The eNB then transmits an uplink or downlink grant over a primary carrier, the grant comprises triggering information for the UE to send an ap-SRS over the indicated carrier using the selected set of UE-specific SRS parameters. In one embodiment of joint signaling, the plurality of sets of UE-specific SRS parameters are signaled together in a single RRC transmission. In another embodiment of separate signaling, each set of UE-specific SRS parameters is signaled independently.

  • Patent number: 8877943
    Abstract: A precursor SnBZM for a dopamine receptor radiotracer and a method for preparing the same are revealed. The precursor includes a tributyltin group (Bu3Sn) that is easy to be replaced. Thus a dopamine receptor radiotracer 123I-IBZM can be produced at high yield rate by a substitution reaction of the precursor. At the same time, both the method for preparing the precursor SnBZM and a method for preparing a reference standard IBZM are simplified. Moreover, stability of each product is improved.

  • Publication number: 20140321385
    Abstract: In wireless OFDMA systems, midamble is used to facilitate downlink (DL) channel estimation. Midamble signals are transmitted by a base station via a midamble channel allocated in a DL subframe. In a novel symbol-based midamble channel allocation scheme, a midamble channel is allocated in the first or the last OFDM symbol of multiple resource blocks of the subframe, while the remaining consecutive OFDM symbols are used for data transmission. The symbol-based midamble channel provides good coexistence between midamble signals and pilot signals without inducing additional limitation or complexity. Under a novel midamble channel and sequence arrangement, both code sequence and either time-domain or frequency-domain location degrees-of-freedom are considered such that the required number of midamble sequences is substantially smaller than the number of strong interferences.

  • Patent number: 8873489
    Abstract: Signaling methods for UE-specific downlink control channels in OFDMA systems are provided. In a first method, a dynamic downlink signaling in cell-specific radio resources is used to signal UE-specific downlink control channel in UE-specific radio resources. In LTE, a specific DCI format in PDCCH is used to dynamically signal the UE-specific downlink control channel X-PDCCH that resides in legacy PDSCH region. In a second method, a semi-static higher-layer signaling is used to signal UE-specific downlink control channel in UE-specific radio resources. In LTE, RRC signaling is used to semi-statically signal the UE-specific downlink control channel X-PDCCH that resides in legacy PDSCH region. By using UE-specific downlink control channels, significant control overhead reduction can be achieved.

  • Patent number: 8861430
    Abstract: Procedures for point association as well as measurement and feedback required to enable point association for CoMP deployment scenario 4 are proposed. In a first novel aspect, a serving eNB configures a first higher-layer configuration for RSRP measurement to be used by a UE for serving point selection. The higher-layer configuration contains multiple CSI-RS configurations, and each CSI-RS configuration indicates a set of resource elements (REs) or subcarriers in both frequency domain and time domain as one CSI-RS resource with non-zero transmission power. The UE then performs RSRP measurements based on the multiple CSI-RS configurations and reports RSRP measurement results to the serving eNB. In a second novel aspect, the serving eNB configures a second higher-layer configuration for CSI reporting based on the reported RSRP measurement results. In a third novel aspect, the serving eNB sends CSI-RS information to the UE for uplink power control.
