Abstract: A device may use sidelink request and sidelink response (e.g., DSS/STS and DRS) resources (in a sub-band) of different sizes depending on whether the sub-band is a primary sub-band or secondary sub-band. The device may transmit more information in the request/response resources of a primary sub-band than in the request/response resources of a secondary sub-band. The device may transmit small amounts of information in its request/response resources in secondary sub-bands. The resources in the secondary sub-bands may include, for example, reference signals, and signals indicating occupation of the sub-band. The device may utilize tone signaling for request/response signaling in the secondary sub-bands (at least because the amount of information being conveyed in the secondary sub-bands is small) and digital signaling in the primary sub-band (at least because the amount of information being conveyed in the primary sub-band is large in comparison to that being conveyed in the secondary sub-bands).

Abstract: Wireless communication systems and methods related to the discovery and selection of relay devices by internet of everything (IoE) devices are disclosed. For example, IoE devices with low pathloss to a base station can broadcast information during discovery frames that allow other IoE devices to discover them and select them as a relay, if appropriate. The discovery broadcast message from an IoE device can include information to allow a listening IoE device to select a suitable IoE device for relaying its data that satisfies latency parameters while minimizing the energy impact of relaying. Signaling structures are also provided to allow different IoE devices to select slots for broadcasting within the discovery frame in a distributed manner without disrupting existing periodic broadcasts. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods, systems, and devices for dynamic monitoring and scheduling in retransmission are described for wireless communications. For example, a receiving device may receive a data transmission in a first receiver bandwidth, determine that a data packet of the data transmission was unsuccessfully decoded, switch to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth (e.g., based on determining that the data packet was unsuccessfully decoded), and receive a retransmission of the data packet in the second receiver bandwidth. In another example, a transmitting device may schedule a data transmission according to a first receiver bandwidth, receive an indication that a data packet of the data transmission was unsuccessfully decoded, and schedule a retransmission of the data packet according to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth.

Abstract: An apparatus may receive, from a scheduling entity, sidelink grant information in a downlink control channel. After receiving the grant information in the downlink control channel, the apparatus may transmit a request-to-send (RTS) signal comprising an indication of a requested duration of time to reserve a sidelink channel for sidelink data. If the sidelink channel is available for the requested duration of time, the apparatus may receive a clear-to-send (CTS) signal configured to indicate an availability of the sidelink channel for the requested duration of time. Subsequently, the apparatus may communicate, with another apparatus different from the scheduling entity, the sidelink data using the sidelink channel during the requested duration of time. Afterwards, the apparatus may communicate acknowledgment information corresponding to the communication of the sidelink signal with the other apparatus. Various additional and alternative aspects are described herein.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit semi-persistent scheduling (SPS) messages to a set of user equipments (UEs) using respective resources corresponding to each UE. The base station may receive, from each of a subset of UEs from the set of UEs, a negative acknowledgement (NACK) message associated with the SPS messages. The base station may transmit a group downlink control message including information associated with a downlink resource configuration for retransmission of the respective SPS messages to the subset of UEs. The base station may retransmit SPS messages to each of the subset of UEs using the downlink resource configuration.

Abstract: Methods, systems, and devices for wireless communication are described. In an FDD system, a UE may identify an indicator associated with ultra-reliable low latency communications (URLLC) while communicating in a sidelink channel. The UE may also identify dedicated uplink resources in the sidelink channel, and reserve the dedicated uplink resources. The dedicated uplink resources may be reserved for an acknowledgement/negative acknowledgement (ACK/NACK) feedback or for a scheduling request (SR). URLLC data may be communicated, and the reserved uplink resources may be utilized to transmit an ACK/NACK feedback or a SR. In a TDD system, a base station may transmit information identifying dedicated resources for URLLC data. In some cases, a base station may transmit an indicator channel, which a sidelink UE may monitor to determine the presence of URLLC data, and respond accordingly.

Abstract: Methods, systems, and devices for wireless communication are described that support overlapping code block groups (CBGs) for multiple codewords. A receiving device may receive multiple codewords from a transmitting device over a set of spatial layers. The receiving device may determine an association between a set of feedback bits and code blocks (CBs) of the multiple codewords. The association may be based on a CBG configuration, which may bundle one or more sets of CBs of the one or more codewords using time boundaries (e.g., symbols) or based on a uniform or proportional CB distribution. Based on whether decoding of the codewords is successful, the receiving device may transmit the set of feedback bits. The number of feedback bits may be the same regardless of whether one or two codewords are received.

Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. The apparatus may be a first node. The first node receives synchronization information. The first node determines at least one discovery frame based on the synchronization information. The first node receives scheduling data from the second node in one of the at least one discovery frame. The first node determines a first awake period of the second node based on the scheduling data of the second node. The first node determines a second awake period of the first node based on the first awake period. The first node associates with the second node. The first node remains awake for communication in the second awake period.

Abstract: IoE devices signal association requests to relay devices during association slots. An IoE device receives a discovery broadcast from a relay device, listing available tones for association. The IoE device sends a first association request to the relay device using a tone selected from the list. The relay device returns a first response. The IoE device randomly selects a tone from a channel and sends a second request to the relay device with it. A second response is sent to the IoE device after contention. The IoE device creates a list of available tones and sends it to the relay device. An overlapping tone is selected. The relay device sends the selected tone to the IoE device for subsequent data communication. If there is no overlap, the relay device may suggest available tones for use in a subsequent association request. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the disclosure relate to a sidelink signaling mechanism that provides for a combination of single-tone and multiple-tone signaling to reduce overhead, while ensuring reliable signaling. In some examples, a sidelink request signal, such as a source transmit signal (STS), may be a single-tone signal, and a sidelink confirmation signal, such as a destination receive signal (DRS), may be a multiple-tone signal. In other examples, the request signal may be a multiple-tone signal, and the confirmation signal may be a single-tone signal.
