Abstract: A UE apparatus determines UE capability and signals UE capability information to a base station. The UE may signal RF capability information to the base station with reference to at least one band combination and signal other baseband parameter(s) (obp(s)) to the base station. The RF capability information indicate RF capability with reference to at least one other band combination parameter. The obp may be indicated on a per UE basis, a per band basis, a per band combination basis, a per band, per band combination basis; and/or a per CC, per band, per band combination basis. Each band combination may indicate a combination of a numerology, a layer and a bandwidth. In another example, a plurality of basebands may be defined, each baseband indicating a combination of a numerology, a layer and a bandwidth.

Abstract: The disclosure relates to reduced signaling to carry out the linking between new radio (NR) carrier aggregation (CA) band combinations and NR band processing combinations (BPCs), and includes apparatus and methods of receiving, at a modem of a user equipment (UE), a UE configuration from a base station based on UE band combination constraint information, configuring the UE, by a processor of the UE, according to the UE configuration, and performing a communication with the base station, via the modem of the UE, according to the UE configuration. In an implementation, the disclosure includes transmitting the UE band combination constraint information, such as in the form of receiving a total number of layers supported in a CA band combination, and wherein receiving the UE configuration further comprises receiving a CA combination and a BPC configuration in response to the UE band combination constraint information.

Abstract: A UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

Abstract: Aspects of the present disclosure provide a plurality of discovery reference signal (DRS) search modes implemented by the user equipment (UE) during contention-based communication in an unlicensed spectrum. The plurality of DRS search modes may include a first DRS search mode (“Full search mode”), second DRS search mode (“Comb search mode”), and a third DRS search mode (“Thin search mode”). The DRS search modes may be selected by the UE based on the system requirements (e.g., tradeoffs between robustness and complexity against cycle cost). Features of the present disclosure further provide techniques for dynamically switching between the plurality of DRS search modes in order to minimize power consumption while reducing the number of cycles required to locate the DRS.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for adjusting flow rate of transmissions received at a device. A user equipment (UE) determines, in response to detecting a trigger condition, a proposal to adjust feedback provided to a base station (BS) in order to adjust a flow rate of transmissions received at the UE from the BS. The UE adjusts the feedback based on the proposal and at least one additional condition and transmits the adjusted feedback to the BS.

Abstract: Reported CSI may not reflect non-cancelable CRS interference received from an interfering cell, such as when the CSI is computed when CRS interference is not received. To address the issue, a user equipment (UE) may determine an interference cancelation/suppression efficiency (CSE) associated with canceling/suppressing interference from interfering cells. In addition, based on the determined CSE, a UE may compute CSI such that the CSI reflects the true cancelation efficiency of the UE with respect to interfering cell signals. When computing the CSI based on the determined CSE, the UE may report that the CSI is worse than it is to reflect the UE's true cancelation efficiency with respect to the interfering cell signals.

Abstract: Certain example embodiments of the present disclosure provide techniques for joint transmission of channel state information reference signals (CSI-RS) from multiple transmission points (TPs) for channel state feedback and/or TP selection. An example method generally includes coordinating with one or more other TPs to jointly transmit a channel state information reference signal (CSI-RS) to a user equipment (UE); signaling a reporting restriction to the UE; receiving precoding matrix indicator (PMI) feedback from the UE based on the jointly transmitted CSI-RS and subject to the reporting restriction; and selecting one or more of the TPs to serve based on the PMI feedback.

Abstract: Apparatuses and methodologies are described that enhance performance in a wireless communication system using beamforming transmissions. According to one aspect, the channel quality is monitored. Channel quality indicators can be used to select a scheduling technique, such as space division multiplexing (SDM), multiple-input multiple output (MIMO) transmission and opportunistic beamforming for one or more user devices. In addition, the CQI can be used to determine the appropriate beam assignment or to update the beam pattern.
