Abstract: The present implementations relate to codeblock concatenation for improved vulnerable symbol handling. For example, a transmitter user equipment (UE) may, for each of the first codeblock and the second codeblock, a first number of coded bits to be mapped to the first number of resource elements satisfying a vulnerability condition and the second number of resource elements not satisfying a vulnerability condition. The UE further extracts, for each of the first codeblock and the second codeblock, a subset of the first number of coded bits and a subset of the second number of coded bits. The UE further concatenates the subset of the first and second number of coded bits from the first codeblock and the second codeblock, and generates a concatenated codeblock for transmission including the concatenated subset of the first number of coded bits and the concatenated subset of the second number of coded bits.

Abstract: A method, a computer-readable medium, and an apparatus may be a first UE in a bundled TTI comprising a first TTI and a second TTI. The first UE is configured to receive a first data transmission and a first reference signal from a second UE in the first TTI, to transmit a SRS to the second UE, and to receive a second data transmission having one or more transmission parameters adapted based on the SRS in the second TTI. In certain aspects, the first UE is configured to transmit a first data transmission and a first reference signal to a second UE in the first TTI, to receive a SRS from the second UE, to adapt one or more transmission parameters for a second data transmission in the second TTI based on the SRS, and to transmit the second data transmission to the second UE in the second TTI.

A first UE may be configured to receive a first data transmission and a first reference signal from a second UE in the first TTI, to transmit a feedback to the second UE, and to receive a second data transmission having one or more transmission parameters adapted based on the feedback in the second TTI. In certain aspects, the first UE may be configured to transmit a first data transmission and a first reference signal to a second UE in the first TTI, to receive a feedback from the second UE, to adapt one or more transmission parameters for a second data transmission in the second TTI based on the feedback, and to transmit the second data transmission to the second UE in the second TTI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and multiple network coding devices may communicate to reduce multiple network coding devices accepting a same take over request message from the UE for a given data packet. In some examples, the multiple network coding devices may determine respective backoff periods to wait before accepting the take over request message such that each backoff period is different for each network coding device. In some examples, the UE may receive respective broadcast messages from each of the multiple network coding devices that indicate a network coding capability parameter, and the UE may select a network coding device based on the received capability parameter. In some examples, a network coding device may transmit an indication of packet overload and refrain from accepting a take over request message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless device may transmit an orthogonal frequency division multiplexing (OFDM) signal on K subsets of N subcarriers, where the signal includes a sequence of modulated symbols for each subset of the K subsets that is distinct for each subset. The wireless device may receive a reflected OFDM signal that corresponds to the OFDM signal. The wireless device may process the reflected OFD.M signal with K mixers, where mixer frequencies for the K mixers are separated by N subcarriers spacing, to form K portions of a range spectrum from the reflected OFDM signal. The wireless device may combine the K portions to form the range spectrum. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. For example, devices of a wireless communications system may be configured to support various techniques for sidelink communications using an unlicensed spectrum, where such sidelink communications are coordinated at least in part by a network device, such as a base station or entity thereof. In some examples, a base station may determine to offload some sidelink communications to the unlicensed spectrum, which may be based on capability information, system channel loading, application priority, periodicity, or quality of service, among other criteria or combinations thereof. Based on such a determination to offload sidelink communications to the unlicensed spectrum, the base station may transmit an indication for one or more user equipments (UEs) to attempt to perform sidelink communications using the unlicensed spectrum (e.g., based on an evaluation of an availability of the unlicensed spectrum by a UE initiating sidelink transmissions).

Abstract: Methods, systems, and devices for wireless communications are described. User equipment (UE) may communicate sidelink coordination messages to indicate potential interference and select sidelink resources. For example, a first UE may transmit a sidelink coordination message to a second UE that includes a set of identifiers associated with a set of UEs. The second UE may select a first set of sidelink resources for a first sidelink communication with the first UE based on a reference signal received power (RSRP) of the sidelink coordination message and a reservation of a second set of sidelink resources for a second sidelink communication between the first UE and third UE of the set of UEs. For example, the second UE may determine the reservation, select the first set to be non-overlapping a time domain with the second set based on the RSRP, and perform the second sidelink communication with the first UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may identify a set of time and frequency resources reserved by one or more second UEs for one of sidelink transmissions by the one or more second UEs to the first UE or to one or more third UEs (e.g., type A), or sidelink transmissions by the first UE to one or more third UEs (e.g., type B), and may select a first indicator and a second indicator for the reservation. The first indicator of a time resource and the second indicator of a frequency resource may be associated with the identified set of time and frequency resources for the reservation. The UE may transmit a coordination message that includes the first indicator and the second indicator, and includes an indication that the message is associated with type A or type B reservations.

Abstract: A first user equipment (UE) receives sidelink resource reservation information over sidelink from one or more UEs. The first UE transmits inter-UE coordination information in a sidelink transmission based on a probability threshold being met. A wireless device may receive one or more of a status of a UE, a capability of the UE, or a report. The wireless device may configure the UE with a probability threshold for transmission of inter-UE coordination information in a sidelink transmission.
