Abstract: A method for communication by an edge communication device with a network via a relay communication device includes synchronizing to a network using an initial synchronization signal, associating with a relay communication device, entering a power saving state, awakening from the power saving state, searching for a periodic secondary relay synchronization signal (SRSS) transmitted by the relay communication device using an SRSS search window having a duration longer than a duration of a network search window for searching for the initial synchronization signal, synchronizing to the relay communication device based on the SRSS signal, and transmitting data to the relay communication device based on the synchronizing to enable the relay communication device to relay the data to the network.

Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a first user equipment (UE) may receive a control message from a second UE indicating resources that are reserved for communications between the first UE and the second UE. The first UE may transmit a first control message and a second control message for reassurance of the reserved resources. The first UE may transmit a first control message for reservation reassurance, and the first control message may indicate a resource configuration for a second control message for reservation reassurance. The first UE may transmit an indication of the reserved resources, resource reservation reassurance information, or both via the second control message. A third UE may receive the first and second control messages and may refrain from communicating on the reserved resources based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include an eNB predetermining a plurality of bandwidth parts to monitor based on resource reservation information received from at least one base station, and transmitting information indicative of the predetermined bandwidth parts in a radio resource control (RRC) message. In some cases, a base station may transmit information indicative of predetermined bandwidth parts including a monitoring schedule to monitor either the first bandwidth part or the second bandwidth part in a timeslot of a set of timeslots. Another method may include receiving a predetermined monitoring schedule from a base station, and selecting a plurality of bandwidth parts to monitor on a physical downlink control channel based on the received schedule.

Abstract: Aspects described herein relate to reporting feedback for semi-persistent scheduling (SPS) configuration updates. SPS communications can be activated over SPS resources with an access point. SPS update resources related to a configured periodicity for receiving SPS updates to SPS resource grants over a control channel can be determined. It can also be determined whether a SPS update is received in the SPS update resources over the control channel. Feedback can be transmitted to the access point, where the feedback indicates whether the SPS update is received over the SPS update resources.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may receive, from a base station associated with the first UE and a second UE, a downlink control information activating a set of configured grant resources for transmissions from the second UE to the first UE. The UE may transmit, according to the downlink control information, a feedback message to the base station confirming receipt of the downlink control information.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first set of resources for communications over a sidelink communication link between the first UE and a second UE. The first UE may transmit, to the second UE via the sidelink communication link, a first sidelink control information including a reverse sidelink scheduling indicator based on determining the first set of resources. The first UE may additionally transmit, to the second UE via the sidelink communication link, a second sidelink control information indicating a second set of resources for reverse sidelink transmissions from the second UE to the first UE over the sidelink communication link, where transmitting the second sidelink control information is based on transmitting the first sidelink control information. The first UE may receive, from the second UE, a reverse sidelink message in response to transmitting the second sidelink control information.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus attempts to receive a downlink transmission from a base station and determines to transmit a NACK to the base station for the downlink transmission. The UE transmits the NACK to the base station in a common resource in an uplink control channel, wherein the common resource is common to multiple UEs communicating with the base station. The UE may also transmit the NACK using a resource granted to the UE in the uplink control channel. Thus, the transmission of the NACK in the common resource may comprise a repetition of the NACK transmitted using the resource granted to the UE. The common resource may comprise a Non-Orthogonal Multiple Access (NOMA) resource. Thus, the UE may apply a NOMA sequence to the NACK prior to transmission of the NACK in the common resource.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration indicating a set of occasions configured for sidelink communications for the UE. The sidelink communications may include at least one of sidelink traffic, semi-persistent scheduling traffic, or a combination thereof. The UE may receive a control indication associated with a radio network temporary identifier. The control indication may include a downlink control information. In some examples, the UE may skip a first pre-scheduled occasion of the set of occasions configured for sidelink communications based on the control indication, and may perform sidelink communications during a second pre-scheduled occasion of the set of occasions after skipping the first pre-scheduled occasion.

Abstract: Various aspects described herein relate to techniques for managing downlink control information (DCI) in wireless communications (e.g., 5G NR). In an aspect, the method includes receiving a radio resource control (RRC) message, identifying a transport block size (TBS) based on the received RRC message, receiving DCI on a downlink channel with the DCI including a resource assignment, identifying a modulation order using a modulation and coding scheme (MCS) in an MCS field of the DCI, where the size of the MCS field is one bit or two bits, and calculating a coding rate based on at least the identified TBS, the identified modulation order and the resource assignment.

Abstract: Aspects of the present disclosure provide techniques to reduce overhead and improve resource management by efficiently selecting RSMA spreading code for periodic traffic in IoE devices. For example, in accordance with one technique, the IoE device, during an initial access to the base station, may notify the base station of the traffic periodicity of the IoE device such that the base station may assign a spreading code from a dedicated pool that is not utilized during the periodic access of the device. Additionally or alternatively, another technique to reduce overhead and improve resource management may include the IoE devices broadcasting the selected RSMA spreading code that the IoE devices intends to use in discovery broadcasts (DBs) along with the IoE device traffic periodicity such that the IoE devices may autonomously manage selection of RSMA spreading code that avoids collisions for the same traffic periodicity.
