摘要:
The application relates to the removal of one of the links in multi-flow HSPA but the proposed method is also applicable to normal HSDPA operation during handover. In particular the application aims at minimizing the negative impact of a removed radio link, i.e. drop of packets and/or delays. According to the proposed method, in which the radio link to be removed is via a first Node B NB1 (RL Removal Req), the NB1 ends the pending data transmission and informs the controlling RNC about the data which was not transmitted, in particular in the form of the lowest sequence number in its buffer. Subsequently, the RNC decides, based on this sequence number, which data packets need to be retransmitted on a second radio link via a second node B NB2, and instructs NB2 accordingly (Data Forwarding).

The present invention addresses apparatuses, methods and computer program product for providing enhanced codeword re-transmission for multi-codeword in 4 antenna branch HSDPA MEMO wireless communication network, thereby preventing getting stuck in higher than rank 1transmissions. When a negative acknowledgement signaling is received from a terminal upon transmission including a first and a second codeword to the terminal, the codeword not associated with the negative acknowledgement signaling is replaced with a temporary codeword, and a transmission a re-transmission of the codeword associated with the negative acknowledgement signaling and the temporary codeword to the base station is caused.
摘要:
A system for determining location information for a wireless device is described. The system includes a UE, a LE and multiple LMUs. The LE sends, to the LMUs, reception instructions with characteristics of the signal transmission from the UE and each LMU receives, from the LE, the reception instructions. The UE sends a signal transmission. Each LMU receives the transmitted signal from the UE, determines locating information based at least in part on the received signal and sends the locating information to the LE. The LE receives the locating information regarding the transmitted signal and determines a location of the UE based at least in part on the received locating information. Methods, apparatus and computer readable media are also described.
摘要:
A method, apparatus, and computer program product are provided for inter-radio access technology carrier aggregation mobility enhancement. The apparatus receives a mobility reporting parameter from a first network node. The apparatus measures parameters of signals received from the first network node and one or more second network nodes based on the measurement reporting parameters. The apparatus generates a measurement report based on the measurement reporting parameters and the measured parameters of the signals, transmits the measurement report to the first network node, and receives a mobility parameter from the first network node based on the measurement report. The measurement reporting parameters include report configuration information for configuring the measurement report based on measured parameters obtained for designated signals received from the first network node and for signals received from the one or more second network nodes.
