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： Certain aspects of the present disclosure provide techniques for coupling a structure in which aperiodic channel state information reference symbols (CSI-RSs) are received with the content and timing of channel feedback. An example method generally includes receiving a request for channel feedback identifying a type of channel feedback to be provided to the BS and a type of CSI-RS to be used for generating the identified type of channel feedback, transmitting an indication of an amount of time used to generate the identified type of feedback based on the identified type of CSI-RS, receiving a triggering signal indicating at least a location of one or more CSI-RSs and a time at which the UE is to report the channel feedback, receiving the one or more CSI-RSs in the indicated location, generating the channel feedback based on the one or more CSI-RSs, and transmitting the generated feedback to the BS.

摘要： Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based on the new transmission strategy.

摘要： Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

摘要： A multi-band user equipment (UE) is configured to operate in a single frequency band mode or a multiple frequency band mode. When operating in a single frequency band mode, the UE activates a bypass switch to route uplink signals of a first band around a multiplexer and reduce the insertion loss for the band.

摘要： System(s) and method(s) that facilitate assignment mismatch recovery are provided. A projected level of resources required to satisfy one or more communication constraints (e.g., inter-cell and intra-cell interference) is generated. The projected resources are contrasted with scheduled resources and a determination is made as to whether a mismatch between assigned and projected resources exists. A mismatch is recovered through an adaptive response that feeds back magnitudes for the communication resources which are compatible with the communication constraints.

摘要： Systems and methods of scheduling sub-carriers in an OFDMA system in which a scheduler takes into account channel conditions experienced by the communication devices to optimize channel conditions. The scheduler can partition a set of sub-carriers spanning an operating bandwidth into a plurality of segments. The segments can include a plurality of global segments that each includes a distinct non-contiguous subset of the sub-carriers spanning substantially the entire operating bandwidth. One or more of the global segments can be further partitioned into a plurality of local segments that each has a bandwidth that is less than a channel coherence bandwidth. The scheduler determines channel characteristics experienced by each communication device via reporting or channel estimation, and allocates one or more segments to communication links for each device according to the channel characteristics.
