Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a transmitting user equipment (UE) may receive control signaling indicating a configuration including criterion for selecting a sensing mode for a sidelink resource selection procedure. The transmitting UE may select the sensing mode based on the configuration and a duplex mode configured for a sensing window and determine available resources based on the performing channel sensing according to the selected sensing mode. The transmitting UE may then select one or more of the available resource to transmit one or more sidelink message to a receiving UE.

Abstract: Aspects enable and provide techniques for sidelink communication resource configuration and management. A first user equipment (UE) negotiates with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication. Each of the plurality of ComReSets has a corresponding periodicity of one or more hyper-frames. The first UE communicates with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet.

Abstract: Certain aspects provide a method for wireless communication. The method generally includes determining a first configuration for sidelink (SL) communication by a user-equipment (UE), determining a second configuration for uplink (UL) or downlink (DL) communication by the UE, the first configuration and the second configuration being determined to allow the UL or DL communication to overlap in time domain with the SL communication, and transmitting the first configuration and the second configuration to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A first device and a second device may communicate via a channel. The first device may generate and transmit a reference signal, which may be a distortion probing reference signal with a high peak to average power ratio. In one implementation, the first device may use the reference signal as an input for a neural network model to learn a nonlinear response of the second device transmission components. In another implementation, the second device may sample the generated reference signal, and use the samples as inputs for a neural network model to learn the nonlinear response. The first device and the second device may exchange signaling based on learning the nonlinear response, and each device may compensate for the nonlinear response when communicating via the channel.

Abstract: Methods, systems, and devices for wireless communications are described. A frequency band configuration for a full-duplex slot may be indicated, where a frequency band configuration may include one or more downlink frequency bands and one or more uplink frequency bands. In some cases, a frequency band configuration may also include one or more guard bands. A user equipment (UE) may determine the frequency band configuration for a full-duplex slot based on a frequency configuration indication, which may include an index for a table of frequency band configurations, one or more bitmaps, or respective start and length indications for each frequency band. A frequency band configuration may apply to one slot or to multiple slots.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a user equipment (UE) receives, from a base station (BS), an indication of a first set of resource blocks (RBs) to receive a first downlink (DL) transmission in a time interval, the UE receives, from the BS, an indication of a dynamically allocated second set of RBs to receive a second DL transmission from the BS in the time interval, and the UE alters one or more parameters of a receiver, based on the second set of RBs, when receiving the second DL transmission on the second set of RBs. Altering the one or more parameters may include switching a phase-locked loop (PLL) of the receiver to a center frequency determined based on the second set of RBs.

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. A mobile device receives a control signal having a first bandwidth. The mobile device receives a data signal having a second bandwidth different from the first bandwidth. The control signal and the data signal are received over a single carrier frequency. The data signal is transmitted after the control signal such that the data signal and control signal are separated by a time interval. The time interval is based on a switching latency of the mobile device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more messages indicative of uplink semi-persistent scheduling (SPS) resources and downlink SPS resources allocated to the UE, the uplink SPS resources and the downlink SPS resources being within a frequency band used for full duplex communications by the UE. The UE may modify parameters associated with the full duplex communications on the uplink SPS resources, the downlink SPS resources, or both, based at least in part on instances of the uplink SPS resources at least partially overlapping in time with instances of the downlink SPS resources. The UE may apply the one or more parameters, after modification, to transmission of uplink communications over the instances of the uplink SPS resources, reception of downlink communications over the instances of the downlink SPS resources, or both.

Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, information via a sidelink interface between the first UE and the second UE. The UE may transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement feedback using a sidelink feedback channel resource of a sidelink resource pool via a sidelink component carrier based at least in part on the information received from the second UE. Numerous other aspects are provided.
