摘要： Systems and methodologies are described that facilitate resource management in a wireless communication system. Various techniques described herein can enable a network cell in a wireless communication system (e.g., a macro cell) to mitigate the effects of interference on other surrounding network cells (e.g., femto cells embedded within the coverage of the macro cell). For example, a network cell can allocate control resources that overlap control resources of a nearby cell and assign resources within the region of overlap only to users that will not cause substantial interference to the nearby cell. As another example, a network cell can utilize a control channelization that partially coincides with a control and/or random access channelization of a nearby cell. The network cell can subsequently elect not to use the control resources in the coinciding region in order to enable the nearby cell to control the effects of interference though data scheduling.

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.

摘要： A UE receives a first channel state information reference signal (CSI-RS) on a first set of beams and receives a second CSI-RS on a second set of beams. The apparatus determines a channel quality indicator (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI) based on the first CSI-RS. The apparatus reports the CQI and RI using an uplink control channel and indicates the PMI using a precoded SRS transmission. The precoded SRS transmission may be precoded based on a dissimilarity between the first CSI-RS and the second CSI-RS. The first CSI-RS may comprise a predefined precoder, and the second CSI-RS may comprise a decoder based on an uplink channel estimate of a non-precoded SRS from the UE.

摘要： Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e. g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e. g., using time division multiplexing (TDM)).

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： Enhancement of channel state information-interference management (CSI-IM) resource configuration is disclosed. The CSI-IM resource configuration may include quasi-colocation (QCL) assumption information specifically for the CSI-IM resource. A compatible user equipment (UE) would receive a CSI report setting configuration for preparing a CSI report on channel information. The UE would obtain a CSI-IM resource configuration including the QCL assumption information associated with a reference signal for either channel or interference feedback. The UE receives the reference signal using the QCL assumption information and measures the interference observed with the reference signal. The UE would then transmit a CSI report indicating the interference observed based on the CSI-IM resource configuration.
