Abstract: Apparatuses, systems, and techniques for obtaining a robot control policy. In an embodiment, a first policy is trained to generate an action sequence based on a reference demonstration that provides, for one or more time steps, reference states of a human hand and an object. The training includes obtaining the reference demonstration, generating, for the one or more time steps, a sequence of actions for controlling a robot end effector to interact with the object, computing, based on the sequence of actions and the reference states, one or more rewards, and updating parameters of the first policy based on the one or more rewards. The rewards are computed based on an anatomy mapping between the human hand and the robot end effector and one or more spatial envelopes for the robot end effector. A second policy is trained, using the first policy, to generate robot actions based on perception data.

Abstract: Methods, systems, and devices for wireless communications are described herein. A transmitting device (e.g., a user equipment (UE), a network entity) may generate a low-density parity-check code according to a base graph, which may be defined by variable nodes and check nodes. The base graph may support second degree variable nodes in the information nodes of the base graph and a larger quantity of second degree nodes associated with higher significance bits than with lower significance bits. Higher significance levels (e.g., bits) may correspond to higher channel reliabilities. The base graph may be a universal base graph or may include additional rules specific to probabilistic shaping. In some examples, an interleaver may be defined to map the base graph to symbols. In some cases, the UE may report its capability to support one or more interleavers, or the network entity may configure the UE with an interleaver.

In some cases, a first wireless device may communicate, with a second wireless device, a control signal indicating a systematic polar code configuration, the systematic polar code configuration indicating for the first wireless device to perform systematic polar encoding on a first set of bits associated with a non-uniform bit distribution.

In such cases, the systematic polar codeword may include a set of parity bits and a set of systematic bits. Thus, the first wireless device may transmit at least the set of parity bits of the systematic polar code.

Abstract: Low density parity check (LDPC) coding techniques may involve puncturing a parity check column and not puncturing a systematic LDPC column (e.g., transmitting the full systematic LDPC code). For example, the base graph matrix may not include punctured systematic nodes. The parity check column that is punctured may be a double edged node (e.g., have at least one entry with two edges or degrees). The remainder of the parity check columns may form a triangular matrix, which may simplify encoding. The transmitting device may map coded bits to a modulation constellation such that systematic bits, and bits of a check node connected to the punctured column, are transmitted in higher-reliability portions of the modulation constellation.

Abstract: This disclosure provides methods, components, devices and systems for techniques for feedback message payload size correction. For example, techniques described herein may enable cyclic redundancy check (CRC) computation using a modified set of bits to differentiate between a CRC computed based on a relatively shorter hybrid automatic feedback request (HARQ) message and a CRC computed based on a relatively longer HARQ message. For example, a user equipment (UE) and a network entity may compute the CRC based on appending a quantity of ones to the payload prior to computing the CRC, by reversing an order of information bits of the payload prior to computing the CRC, or by using HARQ size-specific CRC computation function to compute the CRC such that a CRC function for a relatively larger HARQ message may be different from a CRC function for a relatively shorter HARQ message.
