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: 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.

Abstract: Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is scheduled to transmit in a first slot and a second slot after the first slot. The first UE may then transmit, to a second UE, a first set of data in the first slot based on determining that the first UE is scheduled to transmit in the first slot and the second slot. In some examples, the first UE may determine whether a power estimation capability of the second UE satisfies a threshold. In some cases, the power estimation capability may be based on a correspondence between transmissions in the first slot and expected transmissions in the second slot. Based on the power estimation capability of the second UE, the first UE transmits data in a symbol reserved for automatic gain control at the second slot.

Abstract: A transmitting user equipment (UE) may perform resource hopping for a periodic sidelink resource reservation by scheduling a plurality of periodic sidelink resources with a first periodicity, the plurality of periodic sidelink resources being shifted at a first offset in a frequency domain. The transmitting UE may reduce persistent collisions of periodic or semi-persistent scheduling (SPS) reservation of the sidelink resources with another UE. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) indicating the first offset and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI. The receiving UE may receive, from the transmitting UE, the SCI and the plurality of sidelink transmissions via the plurality of periodic sidelink resources at the first periodicity based on the SCI.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include a receiving wireless device located in a first geographic zone receiving multiple signals from one or more transmitting wireless devices. The receiving wireless device may determine based on the received signals that the one or more transmitting devices are located in a second geographic zone. The receiving wireless device may determine configured transmit power information for each of the signals received from the transmitting wireless devices located in the second geographic zone. The receiving wireless device may estimate a path loss of wireless communications between the first geographic zone and the second geographic zone based on the configured transmit powers received in the signals. The receiving wireless device may communicate within the second geographic location based on the estimated path loss between the first geographic region and the second geographic region.
