Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive a wireless communication signal. The wireless communication device may process the wireless communication signal using a digital post distortion receiver based at least in part on performing a multi-level coding (MLC) set partitioning operation, wherein performing the MLC set partitioning operation comprises partitioning a quadrature amplitude modulation constellation set by bounding a maximum Euclidean distance of an error associated with decoding one or more least significant bits. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive a plurality of beams through a plurality of different receive beam directions, each of the beams including broadcast information on a PBCH. The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.

Abstract: Aspects described herein may enable a network entity to create an mmW cell geometry and/or to seed a base station codebook and a UE codebook to improve a beamforming procedure while maintaining peak performance gain that is provided by scanning narrower beams. The network entity may provide information associated with the base station codebook and the UE codebook to the base station. The network entity may also provide, to the base station, a subframe structure to be used during a beamforming procedure that is based on the base station codebook and the UE codebook. The base station and the UE may perform the beamforming procedure based in the subframe structure using beam orientations indicated in the base station codebook and the UE codebook. From the beamforming procedure, the base station and the UE may determine an access beam to be used in communication between the base station and the UE.

Abstract: A wireless device may identify a first subband in an unlicensed radio frequency spectrum band used to communicate control traffic. The wireless device may identify a second subband in the unlicensed radio frequency spectrum band used to communicate data traffic. The first subband and the second subband may be different. The wireless device may reserve the first subband for a first duration of time for a plurality of wireless devices. The reservation may be based at least in part on an enhanced self-clear-to-send (self-CTS) transmitted over the first subband.

Abstract: Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.

Abstract: Methods, systems, and apparatuses are described for receiving a plurality of spatially multiplexed multiple-input multiple-output (MIMO) single carrier signals in a wireless modem. The signals may be received over multiple antennas associated with the modem, and a multiplication stage of frequency domain equalization may be performed on each of the signals in multiple branches of the modem. Each of the branches may be transformed to a time domain after performing the multiplication stage. An identified differential phase error between the different antennas may then be suppressed in the time domain by rotating a phase of at least one of the signals in each of a number of pairs of the branches. A summation stage of equalization may be performed on a sample-by-sample basis in the time domain on each of the signals after suppressing the identified differential phase error.

Abstract: Certain aspects of the present disclosure provide techniques for envelope tracking schemes for a node in a wireless communication network. One aspect provides a method for wireless communication by a transmitter device. The method generally includes: combining envelopes associated with subbands of an input signal to be amplified for transmission based on a combination function; amplifying, via an amplifier, the input signal to generate a transmission signal, the input signal being amplified based on a combined envelope signal, representing the combination of the envelopes, received at a supply input of the amplifier; and transmitting the transmission signal to a receiver device.
