Abstract: The present disclosure describes a method, an apparatus, and a computer readable medium for hybrid automatic repeat request (HARQ) transmissions. For example, the method may include generating a first codeword for a first information block, wherein the first codeword is a first polar code, and wherein the first information block includes cyclic redundancy check (CRC) bits; transmitting the first codeword to a receiver; determining that the first polar code is not successfully decoded at the receiver based at least on a first message received from the receiver; generating a second codeword for a second information block, wherein the second codeword is a first enhanced polar code, and wherein the second information block does not include any CRC bits; transmitting the second codeword to the receiver; and determining that the second codeword and the first codeword are successfully decoded at the receiver based at least on a second message received from the receiver.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for design of hybrid automatic repeat request (HARQ) feedback bits. The method generally includes obtaining a payload to be transmitted, partitioning the payload into a plurality of blocks, and partitioning each block of the plurality of blocks into a plurality of sections. The method also includes deriving redundancy check information for each section of the plurality of sections, and generating a plurality of codewords, each comprising a block of the plurality of blocks and the redundancy check information for each section of the block, wherein a location of each of the sections in the codewords is determined based on an error rate corresponding to each of the sections.

Abstract: Mechanisms for reduction of channel state information (CSI) feedback overhead are disclosed for full dimensional multiple input, multiple output (FD-MIMO) systems with large dimension antenna ports. In one aspect, rank-dependent CSI antenna port measurements are used in order to limit the number of antenna ports for high rank CSI reporting. Another aspect allows a user equipment (UE) to select subband feedback for aperiodic CSI porting on an uplink shared channel when the UE is to report subband quality and precoding indicators. Another aspect provides for on-demand CSI feedback that dynamically configures CSI feedback parameters. To reduce the signaling overhead, the multiple parameter sets may be pre-configured with different values for dynamic reporting parameters.

Abstract: Enhanced channel state information (CSI) feedback is disclosed for full dimensional multiple input, multiple output (FD-MIMO) operations. In one aspect, a single CSI process is defined that is configured with an azimuth and elevation CSI-reference signal (RS) ports. A user equipment (UE) will send a precoding matrix indictor (PMI) report including a precoding matrix indicator (PMI) for the azimuth ports and a PMI for the elevation ports. One of the PMIs is assigned a low rank. The base station will use the two PMIs to create a whole channel precoding matrix. In another aspect, a single CSI process is configured having a plurality of CSI-RS resources. The UE generates channel measurement information for each of the CSI-RS resources, but only sets a CSI report to the base station of a subset of the total number of resources.

Abstract: A terrestrial UE may receive at least one of a PEI or a paging indication based on a configuration for a search space associated with the at least one of the PEI or the paging indication and transmit a message to a network node via an aircraft-based relay node based on the at least one of the PEI or the paging indication. The relay node may transmit the at least one of the PEI or the paging indication to the terrestrial UE or receive the at least one of the PEI or the paging indication from an NTN device. The relay node may receive the message from the terrestrial UE based on the at least one of the PEI or the paging indication and relay the message to the network node after receiving the message from the terrestrial UE.

Abstract: Certain aspects of the present disclosure provide techniques for configuring for communications on noncontiguous carriers of a single cell. By combining multiple noncontiguous carriers into a single cell, broadcast overhead can be reduced and cell management (i.e., only one cell) can be simplified. For example, a network entity may transmit to a user equipment (UE) configuration information that configures the UE for communications on noncontiguous carriers of a single cell. The network entity and the UE may then communicate on the noncontiguous carriers in accordance with the configuration information.

Abstract: Disclosed are systems and techniques for wireless communications, such as for performing object detection using radio frequency (RF) sensing. In some aspects, a process of the disclosed technology can include steps for receiving a configuration message, wherein the configuration message comprises time-gap information associated with a control signal, receiving the control signal, wherein the control signal comprises radio resource information associated with a sensing signal, and receiving the sensing signal wherein the sensing signal comprises one or more reflected waveforms associated with a detected object. In some aspects, the process can further include steps for transmitting a measurement report corresponding with the detected object. Systems and machine-readable media are also provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may transmit a message indicating that the first device is operating on intermittently available energy harvested from outside the first device. The first device may receive a low-power wakeup signal. The first device may transmit, based at least in part on an energy harvesting state of the first device, an indication that the first device is capable of supporting continuous transmission and reception during a time frame having a configured duration. The first device may communicate during the time frame. Numerous other aspects are described.

Abstract: Aspects described herein relate to receiving a configuration indicating a first codebook subset restriction table restricting a set of precoding matrix indicators (PMIs) for which PMI feedback is to be reported for an antenna array, generating, based on the configuration, PMI feedback for an adaptive configuration of the antenna array based on a second codebook subset restriction table for the adaptive configuration of the antenna array, and transmitting the PMI feedback to the base station. Other aspects relate to transmitting the configuration and/or receiving the PMI feedback.
