Abstract: Methods, systems, and devices for wireless communications are described for shared radio frequency spectrum band access information. A sensing device may monitor one or more frequencies of the shared radio frequency spectrum band and may receive signaling indicating access information (e.g., automated frequency control information). The access information may indicate one or more frequencies of the shared radio frequency spectrum band that are accessible for the sensing device. The scheduling device may obtain the access information from an access point, local storage media, or the like. In some examples, the scheduling device may transmit signaling indicating the accessible frequencies based on a request message from the sensing device. The sensing device may receive the access information and may communicate on one or more of the indicated frequencies accordingly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a sidelink transmission that spans multiple aggregated slots, wherein a first symbol in a slot of the sidelink transmission enables a decoding of the sidelink transmission by the second UE. The first UE may receive, from the second UE, a response based at least in part on the sidelink transmission that spans the multiple aggregated slots. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink transmission that includes a transport block, and may transmit sidelink feedback, for each of a plurality of code block groups included in the transport block, in respective physical sidelink feedback channel (PSFCH) resources. In some aspects, a UE may receive a sidelink transmission that spans a plurality of slots, and may transmitting, for the sidelink transmission, sidelink feedback in at least one of: first one or more PSFCH resources that occur during the sidelink transmission, or second one or more PSFCH resources that occur after the sidelink transmission. Numerous other aspects are provided.

Abstract: Aspects relate to techniques for MCS selection of a packet to be network coded for sidelink communication. A transmitting UE may encode a packet using an MCS that is greater than a normal MCS that may be used for encoding the packet without network coding. The transmitting UE may then transmit the encoded packet to one or more receiving UEs and a network coding device over a sidelink data channel. The transmitting UE may further transmit a network coding request flag associated with the packet to initiate one or more retransmissions of the packet by the network coding device.

Abstract: A sidelink device can perform a network coded sidelink transmission without increasing resource overhead by using resources originally reserved for retransmission of a packet, The sidelink device can reuse the reserved resources when retransmission is not needed based on feedback of the initial sidelink transmission. In one aspect, the sidelink device can use reserved retransmission resources to transmit a network coded transmission of sidelink data received from other sidelink devices. In one aspect, the sidelink device can use the reserved retransmission resources to transmit a network coded transmission including a retransmission of the sidelink device's own sidelink data and sidelink data from other devices.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain an indication that a network node is configured to accept a request for the network node to perform network coding for a communication from the UE. The UE may transmit, based at least in part on the UE being within an area associated with the network node, the request for the network node to perform the network coding for the communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may receive, from a user equipment (UE), an indication to perform network coding for a communication. The first network node may selectively transmit, based at least in part on determining whether the network coding is to be performed by the first network node or a second network node, the communication using network coding. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may receive, from a transmitting device that is configured to perform network coding on information from an originating device, one or more transport blocks (TBs) including the information and associated with an erasure coding scheme. The receiving device may perform decoding using the erasure coding scheme and at least one TB, of the one or more TBs. The at least one TB is selected using one or more time conditions, one or more group conditions, one or more settings indicated by the transmitting device, or a combination thereof. Numerous other aspects are described.
