A method, in a network in which a handover of a wireless device occurs, the User Equipment (UE) moving from a source cell to a target cell, is provided. The method comprises at least: (at the source cell) determining a sequence number (SN) related to a data packet; forwarding at the RLC layer data packets to the target cell, the data packets being previously sent to the UE but unacknowledged by the UE and having SNs inferior to the determined sequence number; and sending the determined SN to the target cell. The method further comprises (at the target cell) sending a first data packet with the determined SN to the wireless device; the determined SN being a demarcation line for using different encryption keys. The UE will decrypt the received data packets having SNs inferior to the determined SN using an encryption key from the source cell; and decrypt received packets having SNs superior to the determined SN using an encryption key from the target cell.

There is provided a method performed by a wireless device for handling user data, wherein the user data are converted into codewords, each codeword having a first group of layers and a second group of layers. The method comprises: receiving an index from a network node, the index indicating a Transport Block Size (TBS) index, a Redundant Version (RV) and a differential modulation; determining a TBS based on the received index; determining a redundant version value based on the received index; determining a first modulation order for the first group and a second modulation order for the second group of a codeword, based on the differential modulation; and performing one of decoding and encoding the codeword based at least on the determined first and second modulation orders, the determined TBS and the determined redundant version value.

A method in a first network node, which comprises a primary Radio Link Control (RLC) entity is provided. The method comprises: receiving packets from a PDCP entity and sending packets to a PDCP entity; separating the received packets into at least a first group and a second group; assigning sequence numbers to the packets of the first group from a sequence number range allocated to at least one the secondary RLC entity in a second network node, the at least one secondary RLC connected to the primary RLC entity through a RLC channel; sending the packets of the first group with the assigned sequence numbers to the at least one secondary RLC entity.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE that receives a multicast/broadcast data transmission via a group bearer. The UE receives a paging message including a type of the group bearer. In addition, the UE determines whether to remain in or change to an RRC idle mode or an RRC connected mode based on the type of the group bearer received in the paging message.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE that performs a PTT/PTX call setup for communication via MBMS. In a first configuration, the UE sets up a unicast bearer with an eNB, and sends group call setup signaling to the eNB while setting up the unicast bearer. In a second configuration, the UE sets up a unicast bearer with an eNB, and receives group call setup signaling from the eNB while setting up the unicast bearer. In a third configuration, the UE receives a group page while in an RRC idle state, and receives group call setup signaling based on information in the group page.
摘要:
In one embodiment, for each of one or more users, the user having provided one or more opinions concerning one or more products, deriving one or more opinion records from the one or more opinions, wherein each opinion record is derived from a specific opinion provided by the user concerning a specific product; generating a user-preference profile based on the one or more opinion records, wherein: the user-preference profile comprises one or more user-preference vectors corresponding to the one or more products; and each user-preference vector comprises one or more features of the corresponding product and one or more feature scores respectively corresponding to the one or more features.
摘要:
The present invention is directed to a biodegradable system for the controlled release of bioactive substances. This system comprises novel biodegradable and biocompatible polyphosphoesters that carry positive charges. Process for making these polyphosphoesters, compositions containing these polyphosphoesters and biologically active substances, articles and methods for delivery of drugs and genes using this system are described. A controlled gene delivery system based on these polyphosphoesters is prepared by complex coacervation of nucleic acid (DNA or RNA) with polymers. The release rates can be manipulated by adjusting the charge ratios of polyphosphoesters to nucleic acids. This gene delivery system yields a higher gene expression in muscle when injected intramuscularly.
摘要:
A method in a User Equipment (UE) for activation or deactivation of a carrier in a communication network supporting carrier aggregation is provided. The method comprises: receiving a control signal for a transmission of a carrier activation or deactivation message command, the control signal including an indication of a first resource for the UE to transmit a feedback message to a network node; receiving a carrier activation or deactivation message; wherein the carrier activation or deactivation message comprises an indication of a second resource for the UE to transmit the feedback message to the network node; decoding the received carrier activation or deactivation message; and sending the feedback message using one of the first resource and the second resource based at least on a result of the decoding of the carrier activation or deactivation message. A UE for performing this method is also provided.
摘要:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines whether the UE is located within a sub-region of an MBSFN area based on one or more parameters. The UE receives based on the determination a service over broadcast in the sub-region of the MBSFN area or over unicast outside the sub-region. In an aspect, the MBSFN area may be smaller than a unicast area. In an aspect, adaptive retransmission with a group NACK approach may be used to improve an SNR and reliability.
摘要:
A network reserves a plurality of temporary mobile group identities (TMGIs). For each of the plurality of reserved TMGIs, the network establishes an evolved multimedia broadcast multicast service (eMBMS) session in at least one preconfigured multicast broadcast single frequency network (MBSFN) area. The network receives a request to form an adhoc group communications service enabler (GCSE) group including a plurality of target UEs; an assigns one of the plurality of TMGIs to the adhoc GCSE group.
