Abstract: This disclosure provides systems, methods, and devices for wireless communication that support an index modulation (IM)-based acknowledgement codebook so use with sidelink feedback. In a first aspect, a first UE receives at least one sidelink transmission from a second UE with a sidelink control information (SCI) message that triggers least one IM-based feedback message codebook. The first UE may determine an IM-based feedback message sequence, determine, based on the feedback sequence, a resource for transmission of the IM-based feedback message, wherein a resource index corresponds to the determined feedback message sequence. The first UE may then transmit the IM-based feedback message codebook on the determined resource to the second UE over the sidelink. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support sidelink transmission resource aggregation for in-coverage new radio sidelink (NR SL) operations. In a first aspect, a method of wireless communication includes obtaining a sidelink aggregation factor identifying a number of sidelink resource slots available to a user equipment (UE) to add to each sidelink resource slot allocated in a grant of sidelink channel access from a serving base station. The UE may then receive a sidelink transmission grant identifying at least one granted sidelink resource slot, and determine an aggregated set of sidelink resource slots for each granted sidelink resource slot. The UE may then transmit sidelink communications using the aggregated set of sidelink resource slots for each granted sidelink resource slots used for the sidelink communications. Other aspects and features are also claimed and described.

Abstract: Wireless communications systems and methods related to autonomous sidelink communication are provided. A first user equipment (UE) communicates, in a first subband of a plurality of subbands within a shared radio frequency band during a first time period, first sidelink control information (SCI) associated with a second subband of the plurality of subbands. The first UE communicates, with the second UE, first sidelink data in the second subband during the first time period based on the first SCI. The first UE communicates, with the second UE in the first subband during a second time period, second SCI associated with a third subband of the plurality of subbands, the third subband being different from the second subband based on a frequency hopping pattern. The first UE communicates, with the second UE, second sidelink data in the third subband during the second time period based on the second SCI.

Abstract: Wireless communications systems and methods related to providing subchannel selection or recommendation and/or channel state information (CSI) for sidelink communications (e.g., operating in mode-1 radio resource allocation (RRA) via a buffer status report (BSR) are provided. A first user equipment (UE) transmits, to a base station (BS), a BSR indicating subchannel information associated with one or more UEs. The UE receives, from the BS in response to the BSR report, a grant for transmitting a first sidelink transmission to a second UE of the one or more UEs. The UE transmits, to the second UE based on the grant, the first sidelink transmission.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive control signaling comprising an indication of a format for a channel state information report indicating channel state information for a sidelink channel between the first UE and a second UE. The first UE may determine the channel state information for the sidelink channel between the first UE and the second UE. The first UE may configure a layer one uplink control message to indicate the channel state information report according to the format. The first UE may transmit, based at least in part on the format, the layer one uplink control message to a base station indicating the channel state information report.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may perform a first transmission to one or more receiving devices, the first transmission associated with a transmission type. The transmitting device may determine a feedback response for the first transmission based on monitoring for feedback messages from the one or more receiving devices in response to the first transmission. The transmitting device may select a contention window size for performing one or more subsequent transmissions based at least in part on the feedback response and the transmission type. The transmitting device may perform the one or more subsequent transmissions in accordance with a clear channel assessment procedure using the selected contention window size.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support improved assignment techniques for dynamic group common physical control channels. In some cases, a user equipment (UE) may receive a control message via a group common control channel. The control message may be monitored by a plurality of UEs, and the control message may include one or more control information segments for a set of UEs of the plurality. The control message may include one or more integer values associated with respective control information segments and a prime number. The integer values and the prime number may be configured to address each UE of the set of UEs. The UE may process the prime number, the integer values, and an integer value that corresponds to an identifier (ID) of the UE to determine applicability of the control message to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a configuration message indicating a group common control resource allocated to a set of UEs that includes the UE, identifying a hashing function assigned to the UE for detecting control messaging communicated via the group common control resource that is addressed to the UE, receiving, via the group common control resource, a control message indicating addressing data and a bitmap, and processing the addressing data using the hashing function and the bitmap to determine applicability of the control message to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, user equipment (UEs) may communicate over sidelink channels in a shared (e.g., unlicensed) channel bandwidth. A UE may implement sub-channel-based occupancy time sharing for the unlicensed sidelink to improve resource usage. The UE may gain access to the shared channel bandwidth for an occupancy time and may transmit a sharing indicator indicating a portion of resources of the shared channel bandwidth for the occupancy time. The UE may transmit a time-division multiplexing sharing indicator to share a portion of slots of the occupancy time, a frequency-division multiplexing sharing indicator to share a portion of sub-channels of the shared channel bandwidth, or some combination thereof. A UE receiving the sharing indicator may identify the shared resources and may transmit in these shared resources (e.g., without performing a full contention process for an occupancy time).

Abstract: In an embodiment, an AP executes a CCA protocol to determine whether to begin transmission within a DMTC window of a radio frame having first and second blocks of subframes. The AP transmits a multi-subframe DRS within the DRS subframes that is scrambled in accordance with a CSI-RS scrambling rule that determines how the second DRS subframe is to be scrambled based on whether the first DRS subframe is included among the first block of subframes or the second block of subframes. At least one UE monitors the DMTC window, and descrambles the CSI-RSs in the multi-DRS subframe based on a CSI-RS descrambling rule that determines how the second DRS subframe is to be descrambled based on whether the first DRS subframe is included among the first block of subframes or the second block of subframes.
