Abstract: Systems and techniques are disclosed to enhance the efficiency of available bandwidth between UEs and base stations. A UE transmits a sounding reference signal (SRS) to the base station. The base station characterizes the uplink channel based on the SRS received and, using reciprocity, applies the channel characterization for the downlink channel. As part of applying the channel information, the base station forms the beam to the UE based on the uplink channel information obtained from the SRS. The UE may include an array of antennas, each UE transmitting a different SRS that the base station receives and uses to characterize the downlink. Multiple UEs (or a single UE with multiple antennas) transmit SRS at the same time and frequency allocation (non-orthogonal), but with each sending its own unique SRS. Further, multiple UEs (or a single UE with multiple antennas) may send their SRS at unique time/frequency allocations (orthogonal).

Abstract: Wireless communication devices, systems, and methods relate to selecting transmission parameters that optimize a dimension (e.g., time, frequency, and/or spatial) under a set of constraints. A UE may receive a resource allocation mode indication and a traffic parameter indication from a BS. The resource allocation mode indication informs the UE to optimize along a time dimension, a frequency dimension, and/or a spatial domain. The traffic parameter indication informs the UE what constraints to consider for the transmission parameters. The UE may use this information upon receipt of a reference signal in selecting transmission parameters based on the received reference signal, resource allocation mode indication, and traffic parameter indication. The resource allocation mode may correspond to optimization within a single slot or across multiple slots. Once selected, the UE may transmit the transmission parameters to the BS for use in sending the message to the UE.

Abstract: Disclosed are techniques for determining round-trip time (RTT) of a user equipment (UE). In an aspect, each gNodeB in a plurality of gNodeBs measure signaling data related to an uplink RTT reference signal received from the UE and the downlink RTT reference signal transmitted by each gNodeB. The signaling data comprises one of a processing delay between a time of arrival (TOA) of the uplink RTT reference signal and a time of transmission (TOT) of the downlink RTT reference signal or a total RTT between the TOT of the downlink RTT reference signal and the TOA of the uplink RTT reference signal. The signaling data is sent to a single entity, other than the UE, e.g., another gNodeB or a location server, where signaling data relevant to the UE is aggregated. The aggregated signaling data may be sent to the UE to determine the RTT for the UE or used by the location server to determine the RTT for the UE.

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Abstract: Techniques are described for wireless communication. One method includes identifying a traffic condition associated with data to be transmitted between a network access device and at least one user equipment (UE); selecting, based at least in part on the traffic condition, a dynamic subframe type of a time-division duplex (TDD) subframe; and indicating the dynamic subframe type in a TDD header of the TDD subframe. Another method includes identifying, in a TDD header of a subframe, an indication of a dynamic subframe type of the TDD subframe; and transmitting data or receiving data in a data region of the TDD subframe based at least in part on the dynamic subframe type.

Abstract: Wireless communications systems may configure a subset of allocated resources (e.g., one or more resource elements (REs) of one or more allocated resource blocks (RBs)) as peak reduction tones (PRTs) for a peak-cancelation signal. For instance, wireless communications systems may configure a fixed PRT allocation based on a Costas array. In some examples, each column of a Costas array may correspond to a RB of a set of allocated resources. A transmitting device may thus identify one or more PRT REs based on the Costas array and a mapping of allocated RBs to the columns of the Costas array. For instance, a transmitting device may identify a pattern of PRT REs to use for a peak-cancellation signal based at least in part on a configured Costas array (e.g., where the peak-cancellation signal may reduce peaks of a corresponding data signal to ultimately reduce peak-to-average power ratio (PAPR) of a transmission).

Abstract: Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.
