摘要： The specification and drawings present a new method, apparatus and software related product for precoding vector selection (e.g., in LTE wireless systems). Instead of cycling through all available precoding vectors, a network element such as eNB may select precoding vectors based on a prioritized distribution of precoding vectors within the cell using initialization with a default codebook. This ensures that preferred precoding vectors are selected more often than other precoding vectors. The method is of low-complexity and intended to ensure a reliable performance of devices in LTE networks.

摘要： The specification and drawings present a new method, apparatus and software related product for using elevation beamforming with standardized CSI feedback for evolving deployment scenarios (e.g., in LTE and LTE-A wireless systems). According to an embodiment of the invention, a network element such as eNB may send to a UE reference signals (e.g., CSI-RS) on a plurality of resources or PRBs (e.g., frequency subbands), each resource can be transmitted with one of a plurality of downtilt angles/values. In response, the network element may receive from the UE a feedback report comprising selected by the UE one or more of the plurality of resources/frequency subbands and related information on PMI/ CQI/RI for each selected resource/frequency subband. Then, based on the feedback report, the network element can determine/identify at least one preferred downtilt angle to use for future transmissions to the UE.

摘要： The specification and drawings present a new method, apparatus and software related product (such as a computer readable memory) for adapting local loading of media data to a UE in a wireless network such as LTE. This may include managing a bit rate at which the UE can requests a version of compressed media which are locally cached (for example using local CDN) by triggering the establishment or modification of bearer, at least partially in response to knowledge regarding compression levels of the requested media data being available in the local/closest CDN. As a non-limiting example, the modification of the bearer may include modification of a UE AMBR value of a default bearer or establishment of dedicated bearers and the associated scheduling bit rate targets.

摘要： This invention describes a method for precoding in a transmitter utilizing a multichannel transmission, using a precoder for, e.g., M-QAM (M>4) modulated OFDM systems. The invention describes a new precoding method that is suitable for use, e.g., in an MB-OFDM UWB system especially when targeting for high data rates (above 480 Mbps). This may involve transmitting 16-QAM in place of 4-QAM symbols. The method could be adopted also for some future wireless LANs (local area networks), for future evolutions of 3G and for 4G systems.

摘要： The specification and drawings present a new method, apparatus and software related product for using codebook constructions within CSI feedback framework for evolving deployment scenarios. A network element (e.g., eNB) may send to a UE a channel CSI-RS on a plurality of resources/frequency subbands formed using at least one slowly changing precoder trajectory in a frequency domain, wherein each of the plurality of frequency subbands is embedded with one codeword. In response, the eNB may receive from the UE an information report comprising selected one or more of the plurality of frequency subbands and related information on PMI/CQI/RI for each selected subband. Then the eNB can establish mapping between the each selected frequency subband and the one codeword for the each selected frequency subband and form by interpolation at least one further slowly changing precoder trajectory in the frequency domain based on the received information report.
