Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive one or more transmissions from one or more UEs in a first slot, including a first transmission from a second UE. The first UE may receive the first transmission using a receiver configured with a first gain and may decode the first transmission. The UE may determine a correspondence (e.g., a temporal correlation) between the first slot and a second slot and may configure the receiver with a second gain at the beginning of the second slot based on the correspondence. The UE may determine that a total received signal power in the second slot is associated with the total received signal power in the first slot. The UE may decode one or more transmissions in the second slot based on the receiver having the second gain at the beginning of the slot.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a peer device. The method generates control information to schedule peer-to-peer communication. The control information includes a first portion with a first set of data and a second portion with a second set of data. The method then transmits the first portion of the control information in a first stage using first time and frequency resources. The first portion indicates a control information format of the second portion. The method further transmits the second portion of the control information in a second stage using second time and frequency resources and the indicated control information format.

Abstract: Methods, systems, and devices for wireless communications are described that may enable a user equipment (UE) to transmit sidelink data within an interference avoidance resource scheduling scheme. For example, a UE may determine to segment a data packet for transmission in a vehicle-to-everything (V2x) system (e.g., to ensure that each segment fits within one transmission time interval (TTI)). In some cases, a UE may identify a data packet for transmission, may determine that the size of the data packet exceeds a threshold size, may segment the data packet to ensure each segment fits within one TTI, and may transmit the data packet segments (e.g., to additional UEs), where said transmissions may be discontinuous. In some examples, a UE may determine to segment the data packet and then encode the data packet. Additionally or alternatively, the UE may determine to encode the data packet and then segment the data packet.

Abstract: transmissão e conteúdo de atribuição de agendamento em comunicações sem fio trata-se de métodos, sistemas e dispositivos para transmissões e retransmissões de informações de atribuição de agendamento (sa) e para conteúdo de transmissões de sa. sas podem ser transmitidas durante um período de comunicações inicial, seguidas por transmissões de dados por um certo período de tempo. um dispositivo pode monitorar em relação a transmissões durante o período de sa e, então, monitorar em relação a transmissões de dados durante períodos indicados em uma sa recebida. as sas podem ser retransmitidas de acordo com um padrão de retransmissão que pode fornecer padrões de diversidade de tempo ou frequência de modo a melhorar o recebimento de sas em um dispositivo de recebimento. os padrões de retransmissão podem ser determinados com base em um recurso de um grupo de recursos de sa que é usado para uma transmissão inicial da sa.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, in a first time slot, a set of resources to use for transmission to another UE; evaluate, in a second time slot, whether one or more resources of the set of resources is available; and transmit, based on the one or more resources of the set of resources being available, information to the other UE in a third time slot and using the set of resources, or reselect, based on the one or more resources of the set of resources being unavailable, another resource for transmission of the information to the other UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, radio signals may reach a receiving antenna at a user equipment by two or more paths, which can cause interference (e.g., destructive multipath interference, constructive multipath interference, etc.). To reduce the interference, the user equipment may perform interference suppression, shaping, or both based on choosing radar waveform patterns that are varied across chirps. In one aspect, the user equipment (e.g., a vehicle) may identify waveform patterns selected by nearby vehicles based on side channel or centralized signaling and may suppress or shape interference by selecting waveform parameters based on this information. In one aspect, the pattern of waveform parameters is chosen from a codebook of patterns. The selected pattern can be broadcasted to the other vehicles using a side-communication channel.

Abstract: In one aspect of the disclosure, to improve the performance of device-to-device based relay communication, a method, a computer-readable medium, and an apparatus for performing rate control based on feedback from participating UEs are provided. The apparatus may be a first UE. The first UE may receive a signal from a second UE through a device-to-device communication channel. The first UE may determine a feedback based on the received signal. The first UE may transmit the feedback to adjust transmission of the signal at the second UE. In another aspect of the disclosure, a first UE may transmit a signal to a second UE through a device-to-device communication channel. The first UE may receive a feedback of the signal. The first UE may adjust transmission of the signal based on the feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from another UE, a particular transmission on a particular transmission resource. The UE may transmit, on a feedback resource selected based at least in part on the particular transmission resource, a feedback message using a multiple access signature determined based at least in part on a characteristic of the particular transmission. Numerous other aspects are provided.
