Abstract: Methods, systems, and devices are described for wireless communication at a UE. A base station may select a hybrid pilot configuration including a relatively sparse periodic pilot and a dense pilot embedded in one or more symbols of a low latency burst. A user equipment (UE) may generate a long term statistical average channel estimate based on the periodic pilot and an instantaneous channel estimate (e.g., for demodulation) based on the dense pilot embedded in the low latency burst. The UE may refine the instantaneous channel estimate by converting a control channel embedded with the burst. In some instances, the base station may embed the dense pilots in the first symbol of a burst and transmit subsequent low latency symbols with a reduced density pilot (or without pilot tones).

Abstract: Providing for improved implementation of supplemental wireless nodes in a wireless base station deployment is described herein. By way of example, a donor base station is configured to send a schedule of data transmission to and from a set of UEs served by the base station, and further can provide the schedule and identifiers for the set of UEs to one or more wireless nodes serving the base station. Respective access channel measurements between respective UEs and respective wireless nodes can be forwarded to the base station, which in turn can identify optimal access channels for the set of UEs. Additionally, the donor base station can schedule multiple data transmissions on these access channels in a common transmission time slot, to achieve cell-splitting gains for the data transmissions. Range boosting, differential coding, and supplemental channel quality mechanisms are also provided for various wireless communication arrangements described herein.

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: Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

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: Methods, systems, and devices for half-duplex frequency division duplexing (HD-FDD) hybrid automatic repeat request (HARQ) operation are described. The base station may receive a message from a user equipment (UE) indicative of a duplexing capability of the UE. The base station may then select a HARQ process limit based on the duplexing capability. In some examples, the base station may anticipate a collision between an uplink (UL) transmission and a downlink (DL) subframe based on the selected HARQ process limit. The base station may then schedule a transmission to avoid the anticipated collision. In some examples, the base station may limit a number of configurations available for channel quality indicator (CQI) or a precoding matrix indicator (PMI).

Abstract: Techniques for supporting channel measurement and reporting in a wireless communication system are described. In one design, a cell transmits a cell-specific reference signal (CRS) used for channel estimation and coherent demodulation and a channel spatial information reference signal (CSI-RS) used for channel measurement and channel feedback reporting. The cell may transmit the CSI-RS less frequently than the CRS, or from more antenna ports than the CRS, or on fewer resource elements than the CRS, or a combination thereof. In one design, a user equipment (UE) determines at least one bandwidth part configured for the UE, with each bandwidth part covering at least one subband. The UE receives the CRS and CSI-RS from the cell, determines channel feedback information for the at least one bandwidth part based on the CSI-RS, sends the channel feedback information to the cell, and receives data transmitted by the cell based on the channel feedback information.
