Abstract: An assisting network device receives an incoming signal from a transmitting device. The assisting network device forwards the incoming signal to a receiving device in a beam direction based on a frequency of the incoming signal. A method of wireless communication by a first wireless device includes determining an indication of a frequency domain beam sweeping configuration of an assisting network device. The method communicates a signal with a second wireless device via the assisting network device in a beam direction based on a frequency of the signal. A method of wireless communication by a controlling entity determines a frequency domain beam sweeping configuration of an assisting network device. The method indicates the frequency domain beam sweeping configuration to a first wireless device, via the assisting network device, for communication with a second wireless device in a beam direction based on a frequency of an incoming signal.

Abstract: Certain aspects of the present disclosure generally relate to techniques for compactly describing lifted low-density parity-check (LDPC) codes. A method by a transmitting device generally includes selecting a first lifting size value and a first set of lifting values; generating a first lifted LDPC code by applying the first set of lifting values to interconnect edges in copies of a parity check matrix (PCM) having a first number of variable nodes and a second number of check nodes; determining a second set of lifting values for generating a second lifted LDPC code for a second lifting size value based on the first lifted PCM and the first set of lifting values; encoding a set of information bits based the first lifted LDPC code or the second lifted LDPC code to produce a code word; and transmitting the code word.

Abstract: Various aspects of the disclosure relate to encoding information and decoding information. In some aspects, the disclosure relates to an encoder and a decoder for Polar codes with HARQ. If a first transmission of the encoder fails, information bits associated with a lower quality channel may be retransmitted. At the decoder, the resulting decoded retransmitted bits may be used to decode the first transmission by substituting the retransmitted bits for the original corresponding (low quality channel) bits. In some aspects, to decode the first transmission, soft-combining is applied to the decoded retransmitted bits and the original corresponding (low quality channel) bits. In some aspects, CRC bits for a first transmission may be split between a first subset of bits and a second subset of bits. In this case, the second subset of bits and the associated CRC bits may be used for a second transmission (e.g., a retransmission).

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for use in receiving devices employing at least one iterative process for decoding messages. In certain example aspects, a receiving device may comprise a user equipment (UE) or other like device that may be configured to support device-to-device (D2D) communications, such as vehicle-to-vehicle (V2V) communications, or the like.

Abstract: Encoders, decoders and methods of encoding and decoding data can comprise receiving source symbols in a first sequence, storing the source symbols to a first memory in a second sequence, wherein the first sequence is a first interlacing relative to the second sequence, determining if the memory contains all source symbols of a codeword, wherein the source symbols of a codeword are the symbols used to generate repair symbols for that codeword, generating repair symbols for the codeword, storing the repair symbols to a second memory in a third sequence, interlacing the repair symbols and the source symbols into an output stream as a stream of encoded symbols, wherein the repair symbols appear in the output stream in a fourth sequence, wherein the fourth sequence is a second interlacing relative to the third sequence, and outputting the stream of encoded symbols.

Abstract: Systems and methods utilizing available storage space within a storage system (e.g., as “supplemental” storage) and/or implement less physical storage space in the storage system (e.g., reduced storage overhead) through operation of fragment pre-storage techniques are disclosed. Such fragment pre-storage utilization of the aforementioned available storage space may provide operation emulating larger storage overhead than is actually provided in the storage system, facilitate improved repair rates, and/or facilitate reduced repair bandwidth in the storage system according to embodiments. A fragment pre-storage repair policy may implement source object repair whereby additional fragments for the source object are pre-generated and pre-stored in the storage system as transient fragments, whereby the transient fragments are moved to corresponding storage nodes when those storage nodes become physically present in the storage system.
