Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced sidelink carrier aggregation feedback operations. In a first aspect, a method of wireless communication includes receiving, by a wireless communication device, a sidelink shared channel transmission via a first component carrier. The method also includes obtaining, by the wireless communication device, a feedback resource indication. The method further includes transmitting, by the wireless communication device, a sidelink channel feedback transmission in a sidelink channel feedback transmission resource via a second component carrier different from the first component carrier. The sidelink channel feedback transmission resource is determined based on the feedback resource indication, and the sidelink channel feedback transmission indicates feedback data for the sidelink shared channel transmission. Other aspects and features are also claimed and described.

Abstract: Aspects relate cross-pool resource reservations of resources for sidelink-positioning reference signals (SL-PRS). A wireless communication device can transmit a first SL-PRS resource reservation message within resources in a SL communication resource pool. The first SL-PRS resource reservation message may identify a first SL-PRS resource within a SL-PRS resource pool. The wireless communication device can also transmit a first SL-PRS in the first SL-PRS resource within the SL-PRS resource pool. The wireless communication device can also receive a second SL-PRS resource reservation message within resources in the SL communication resource pool. The second SL-PRS resource reservation message may identify a second SL-PRS resource within the SL-PRS resource pool. The wireless communication device may then receive a second SL-PRS in second SL-PRS resource within the SL-PRS resource pool. The SL communication resource pool may be different from the SL-PRS resource pool.

Abstract: A sidelink user equipment (UE) limits sensing of received sidelink communications during a sensing window. The UE selects resources for a future transmission from a resource pool that is based on the sensed received sidelink communications. The UE also sends the future transmission on the selected resources. Limiting sensing may result from reducing a maximum distance between reservations to less than 32 logical slots. Limiting sensing may be sensing with a reduced sensing duty cycle with discontinuous sensing or sensing for a period of time in response to a trigger. The UE may perform partial sensing for periodic traffic, and limit sensing for aperiodic traffic.

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 transmit a reservation for a sidelink resource for a communication by the UE, wherein the sidelink resource was previously reserved by a transmitter UE for a communication by the transmitter UE; and receive an indication that the sidelink resource is reserved and that the UE is not permitted to reserve the sidelink resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE), may identify a default modulation and coding scheme table and a preconfigured modulation and coding scheme table associated with a resource pool. The UE may receive, from a transmitting communication device, an indication of the preconfigured modulation and coding scheme table to use for upcoming sidelink communications. The UE may then communicate based on the preconfigured modulation and coding scheme table.

Abstract: Apparatus, methods, and computer-readable media for sidelink control information forwarding for sensing procedure are disclosed herein. An example method of wireless communication at a forwarding user equipment (UE) includes receiving, from a forwarded UE, control information, and transmitting, to a sensing UE, a forward message including the control information and information associated with the forwarded UE. An example method of wireless communication at the sensing UE includes receiving, from the forwarding UE, a forward message including the control information containing a first measurement of the control information. The example method also includes obtaining a second measurement of the forward message and determining a ratio of the second measurement to the first measurement. The example method also includes selecting a specific resource based on the ratio and whether the forwarding UE is an intended receiver for the sensing UE or the forwarding UE intends to receive from the forwarded UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may receive an indication of a first set of resources for feedback and an indication of a second set of resources for feedback, where the second set of resources are associated with a smaller quantity of cyclic shifts than the first set of resources. Accordingly, the mobile station may transmit feedback on either the first set of resources or the second set of resources based at least in part on a distance associated with the feedback. As an alternative, the mobile station may compute a timing advance associated with transmission of feedback. Accordingly, the mobile station may feedback that is shifted in time according to the timing advance. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a first UE. The method includes receiving a data transmission from a second UE. The data transmission is associated with a feedback procedure for data transmissions that is based on a distance between the first UE and a transmitting UE. When the first UE (i) cannot successfully decode the data transmission and (ii) cannot determine the distance between the first UE and the second UE, the method includes determining whether one or more criteria are satisfied for sending, to the second UE, a negative acknowledgement (NACK) for the data transmission as part of the feedback procedure, where the NACK indicates the first UE could not successfully decode the data transmission. The method including transmitting the NACK to the second UE when the one or more criteria are satisfied.
