    摘要: A precoding scheme to accommodate user equipment (UEs) having higher Doppler speeds. In such transmission schemes, a different precoding matrix is applied to each orthogonal frequency division multiplex (OFDM) symbol in the transmission stream. Additionally, a downlink control message format is defined to handle assignment of multiple different transmission schemes using the same message format. The downlink control message format includes a control element in one of the message fields along with a set of parameters specifically applicable to the assigned transmission scheme. Based on the value of this control element, the UE sets the specific transmission scheme and determines a set of interpretation rules uniquely associated with that transmission scheme. Using the interpretation rules, the UE is able to read the set of parameters as applied to the selected transmission scheme.

    摘要: Half-duplex (HD) operations enable low cost implementations of LTE terminals. Traditionally, HD operations may be linked to a particular frequency band which may not allow a mix of full-duplex (FD) and HD terminals in the same frequency band. Therefore, certain aspects of the present disclosure provide techniques for enabling coexistence, in a given frequency band, of HD and FD terminals, by introducing frequency bands designated for HD operation and overlapping existing frequency bands designated for FD operation.

    摘要: Various aspects of the present disclosure are directed to periodic over-the-air channel state information (CSI) reporting to serving cells and one or more non-serving cells via a control channel multi-point attachment. The channel state information report may be transmitted based on information indicating how to transmit the channel state information report to the non-serving cell. The information indicating how to transmit the channel state information report may be provided by the serving eNodeB. The information may include a periodicity, offset parameters, timing advance commands, power control commands, and/or an aperiodic report request.

    摘要: Discontinuous reception (DRX) operation may be utilized to maintain connection with user equipment (UE) by increasing the effective control channel transmission periodicity. UEs may be configured with a compatible control channel transmission periodicity such that multiple UEs may share a resource in a time-division-multiplexed manner using DRX offsets and periodicity, effectively extending control channel transmission periodicity through resource overloading.

    摘要: A method, an apparatus, and a computer program product for wireless communication are provided in which a resource assignment utilizing the PDCCH and/or the R-PDCCH may be addressed to a group of UEs, rather than an individual UE, by utilizing a group identifier for indicating to the group that there may be information for any UE in the group in the PDSCH. In this way, the capacity of the PDCCH, which is limited, is multiplied and a potential bottleneck at PDCCH scheduling can be relieved.

    摘要: In macro/RRH setups, channel state information reference signals (CSI-RS) and demodulation reference signals (DM-RS) may be used to decouple control and data transmission. Data transmission (e.g. for LTE Rel 10 and beyond) may be based on CSI-RS and DM-RS, while control may be received from a different set of cells or TxPs via CRS. Certain aspects of the present disclosure introduce a reporting framework, in which configuration of data-serving cells/TxPs may be carried out based on CSI-RS. In certain aspects, a new concept of CSI-RS groups, i.e., a set of CSI-RS ports that a UE considers as one group for precoding matrix indicator (PMI)/channel quality indicator (CQI)/rank indicator (RI) reporting, may be defined.
