Abstract: This disclosure provides systems, methods and apparatus, including computer storage media, for retransmission of sidelink transmissions using network coding with binned feedback. A transmitting device transmits a transport block and a request for a network coding (NC) encoding device to retransmit the transport block to a plurality of user equipment (UEs). The UEs decode the transport block and report an acknowledgment (ACK) or negative acknowledgment (NACK) on a physical sidelink feedback channel (PSFCH) resource associated with a bin for the UEs. The NC encoding device decodes the PSFCH resource for each bin to determine an ACK or NACK status for each bin, and determines whether to encode the transport block in a NC combination packet. The UEs receive the NC combination packet including an encoding of a subset of transport blocks. The receiving devices transmit an ACK or NACK on a PSFCH resource for a bin for each transport block.

Abstract: An apparatus or an add-on module for a, in particular mobile, device, is disclosed. In an embodiment, the device to be localized or the add-on module uses a measuring unit to measure, via suitable sensors, a local electromagnetic field distribution generated by a given infrastructure. An instantaneous position of the add-on module or of the device equipped therewith is then determined by comparing the measured field distribution with a specified map. In order to facilitate tracking of the add-on module or of the device, the measured field distribution and/or the determined position can be sent via a wireless data connection to a server unit.

Abstract: Certain aspects of the present disclosure provide techniques for channel estimation for two-stage sidelink control using sidelink data channel demodulation reference signals (DMRS). A user equipment (UE) can transmit DMRS for the sidelink data channel. The UE may transmit the second stage of the sidelink control using antenna ports or a precoder used for the sidelink data channel.

The receiving device may flexibly determine the DMRS to use for the estimation and demodulation.

Abstract: Aspects described herein relate to sidelink-assisted virtual multi-link. In one aspect, for example, a relay node may serve as an additional virtual antenna panel for a UE by receiving downlink data from a base station via an access link, or receiving uplink data from the UE via a sidelink. The relay node may forward the downlink data to the UE via sidelink, or the uplink data to the base station via the access link. In another aspect, a base station may determine, for a UE, quasi-colocation (QCL) information and a grant for one or both of one or more access link resources or one or more sidelink resources. The base station may further transmit, to the UE, the QCL information and the grant on a downlink communication channel.

The first UE may transmit the bitmaps to the second UE. In some examples, the first UE may generate a bitmap indicating which slots have at least one subchannel that is available, and, for each slot having at least one subchannel that is available, a bitmap indicating which subchannels are available.
