Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may receive a first reference signal from a second device and may generate a channel status feedback message based on the first reference signal. The first device may bundle the second reference signal and the channel status feedback message and may transmit the second reference signal and the channel status feedback to the second device. The first device may initiate a data transfer with the second device based on transmitting the second reference signal and the channel status feedback message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a UE capability message to a base station, the UE capability message including an indication of a UE type, wherein the UE type is associated with at least one of a reduced bandwidth, or a reduced number of antennas, or a combination thereof for the UE. The UE may receive, based at least in part on the UE capability message, a downlink grant for downlink resources for a data transmission in accordance with a resource allocation scheme, wherein the resource allocation scheme is associated with the UE type and a supported bandwidth part of the UE. The UE may monitor a wireless channel based at least in part on the downlink grant. The UE may receive the data transmission based at least in part on the monitoring of the wireless channel.

Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for enabling a single media access control (MAC) layer to control a variety of physical (PHY) layers or entities for multiplexing signals corresponding to each of the PHY layers over an air interface. Here, the MAC layer may include a resource manager configured to determine a time-frequency resource allocation within the air interface for communication with one or more subordinate entities utilizing each of the PHY layers. In this way, The MAC entity may provide dynamic control over the allocation of time-frequency resources within a given resource group, which may include transmission time intervals (TTIs) having multiple time scales.

Abstract: Aspects of the present disclosure provide various wireless communication numerology designs that can maintain symbol boundary alignment while multiplexing different numerologies in wireless communication. The symbols may be scaled for different tone or subcarrier spacings while maintaining the symbol boundary alignment between different numerologies. Maintaining the symbol-boundary alignment between different numerologies enables symbol-level numerology multiplexing. The disclosed numerology designs enable low latency communication and improved interference management, and provide non-ambiguous symbol boundary timing reference for multiplexing different numerologies.

Abstract: Various features pertain to mitigating interference on downlink/uplink channels caused by bursty traffic transmissions. A transmitting node encodes data into transport blocks, each including code blocks in which the data is encoded. The transport blocks are then wirelessly transmitted over a channel specific to a receiving node, where the code blocks of the transport blocks are transmitted without redundant parity code blocks or with a desired amount of redundant parity code blocks. The transmitting node then receives an indication from the receiving node of a number of failed data code blocks. The transmitting node generates an error correction code sufficient to recover all of the failed code blocks and transmits the error correction code within a new transport block along with new data. The receiving node receives the new transport block including the error correction code and then recovers the failed code blocks from the error correction code via erasure decoding, a combination of erasure decoding and error decoding, and/or other suitable techniques at the code block level.
