Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit assistance information indicating a type of in-device coexistence (IDC) interference at the UE, and indicating a set of associated interference parameters that correspond to an interference pattern of the IDC interference in a time domain, a frequency domain, or both. The set of interference parameters and the interference pattern may describe a pattern of the IDC interference in the time domain, the frequency domain, or both. The UE may receive a message indicating one or more operating parameters associated with a time period that is based on the interference pattern. The operating parameters may be based on the type of IDC, the set of interference parameters, and the interference pattern, and may enable the UE to communicate with a network entity to maintain signaling throughput while decreasing effects of the IDC interference.

In-device coexistence interference parameters

The present disclosure provide various methods, computer-readable media, and apparatuses for managing communication paths, which may include at least one direct communication path between UEs, such as a sidelink communication path. Illustratively, an apparatus of the present disclosure may be a UE or component thereof that is configured to establish a direct wireless communication link and an indirect wireless communication link with another UE to carry data associated with one traffic stream. Further, the apparatus may be configured to communicate with the other UE over at least one of the direct communication link or the indirect communication link after the direct communication link and the indirect communication link are established with the other UE.

Path management with direct device communication

Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may communicate one or more messages associated with establishing a sidelink communication connection with a set of UEs, including a second UE. The first UE may transmit a message indicating that the first UE has a data transmission to send. The second UE may receive the message and transmit an indication that a first set of resources is allocated to the first UE for the data transmission. In some examples, the second UE may broadcast the indication that the first set of resources is allocated to the first UE. The first UE may transmit the data transmission over the resources based on receiving the indication that the first set of resources is allocated to the first UE. In some examples, the first UE may perform a listen before talk procedure prior to transmitting the data transmission.

Inter-user-equipment scheduling for sidelink communications

Aspects relate to an allocation of periodic resources where use of the periodic resources is conditional. In some examples, a user equipment (UE) receives a periodic resource allocation along with an indication of a condition for using the periodic resources. For example, the UE may be allowed to transmit on at least one first resource of the periodic resources if the condition is true. Similarly, a base station (BS) may monitor for a transmission by the UE on the at least one first resource if the condition is true.

Conditional use of allocated periodic resources

Apparatus, methods, and computer program products for relaying and side link communication are provided. An example method may include receiving, from a BS via a controlled discovery procedure, a query to verify a sidelink procedure with at least one UE. The example method may further include establishing, via the BS as a L2 relay, the sidelink procedure with the at least one UE. The example method may further include switching from the sidelink procedure to a sidelink PDCP procedure with a hybrid mode, the BS being an L2 relay for the sidelink PDCP procedure. The example method may further include transmitting to the at least one UE via the BS as the L2 relay, or receiving, from the at least one UE via the BS as an L2 relay, one or more PDCP PDUs corresponding to L2.

Sidelink for industrial IoT

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit a request for a network device to establish a resource bundle, of resources to be used by nodes at hops in a time sensitive networking (TSN) bridge for TSN communications to a second UE, with a maximum latency for the TSN bridge. The first UE may transmit the TSN communications to the second UE via the TSN bridge. Numerous other aspects are described.

Resource bundle for time sensitive networking bridge

A base station may configure a first node and at least one second node with an integrated access and backhaul (IAB) network with the multipath multi-hop transmission configuration. The first node and the at least one second node may communicate with the first node through a direct path and a multi-hop transmission including the base station. The first node and the at least one second node may detect transmission failure on the direct path and retransmit the data packet to the multi-hop transmission, on a set of physical resource blocks (PRBs) configured by the base station. The first node may transmit remote buffer state report (rBSR) to the base station, and the base station may configure the set of PRBs for retransmissions based on the rBSR.

Multipath IAB communication including multi-hop

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a semi-persistent scheduling configuration that identifies a plurality of resource occasions each comprising a plurality of resources of a sidelink channel allocated to the first UE for sidelink communication. The UE may identify a rescheduling configuration for scheduling transmission of a first message that has a possible conflict with transmission of a second message during a first resource of the plurality of resources of a first resource occasion of the plurality of resource occasions, the first message having a different priority than the second message. The UE may transmit the second message during the first resource occasion and may transmit the first message via the sidelink channel in accordance with the rescheduling configuration.

Sidelink intra-UE prioritization

Methods, systems, and devices for wireless communications are described. A wireless device may establish connectivity between the wireless device and a user equipment (UE) via a first communication path, and between the wireless device and the UE via a second communication path that includes a relay device. The wireless device may transmit, via the first communication path, a first message in a first format to the UE, including first data, and transmit, via the second communication path to the relay device, a second message in a second format and including the first data, the second format indicating that the relay device is to relay the first data to the UE. The relay device may receive, via a first portion of the second communication path, the first message and may transmit, to the UE via a second portion of the second path, a second message including the first data.

Architecture and protocols to support industrial internet of things and wireless programmable logic controller communications

Methods, systems, and devices for wireless communications are described. A first device node, such as an end station or a user equipment (UE) associated with the end station, may receive, from a controller node of a time-sensitive network (TSN), a configuration for communicating over the TSN. The TSN may include a plurality of nodes that are synchronized according to a common synchronization configuration and that are configured for transmitting messages between the controller node and the first device node within a latency threshold condition configured for the TSN. The first device node may identifying data to transmit to a second device node of the plurality of nodes and may communicating with the second device node via a sidelink connection associated with the wireless radio access network.
