Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine one or more sidelink discontinuous reception (DRX) parameters for a configured sidelink DRX cycle. The sidelink DRX parameters may be selected by the UE or may be indicated by a base station. In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.

Abstract: Wireless communications systems and methods related to communicating in an integrated access backhaul (IAB) network are provided. A first wireless communication device receives synchronization information associated with one or more wireless communication of a multi-hop wireless network. The first wireless communication device determines a transmission timing adjustment for a second wireless communication device of the one or more wireless communication devices based on at least some of the synchronization information. The first wireless communication device transmits a message instructing the second wireless communication device to communicate with a third wireless communication device of the one or more wireless communication devices based on the transmission timing adjustment.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a control node may receive a resource management indication from a network node to identify a resource utilization with communications of the network node; determine, based at least in part on the resource management indication, a collision management configuration for the network node; and transmit information associated with the collision management configuration based at least in part on the determination of the collision management configuration. Numerous other aspects are provided.

Abstract: The present disclosure relates to an efficient demodulation reference signal (DMRS) design to facilitate a user equipment (UE) in performing blind detection of a DMRS sequence to determine if a transmission includes data for the UE. Specifically, features of the present disclosure implement techniques that use DMRS design to facilitate blind detection of a DMRS sequence in order for the UE to determine whether a packet for the UE was transmitted during a particular SPS slot. By utilizing the techniques described herein, the base station may forego using PDCCH to provide new allocation information each time that a packet misses the assigned SPS slot.

Abstract: High frequency wireless communication networks rely on directional transmit and receive beams to achieve large gains and overcome large pathlosses associated with high frequency signals. With highly directional signals, link failure may occur. Network nodes associated with the link failure, may need to identify new beam pairs and establish a new link as quickly as possible. In several aspects, beam sweep procedures are expedited, allowing for rapid link reestablishment. Disclosed techniques allow for rapid link reestablishment with and without beam correspondence.

Abstract: Aspects of the present disclosure describe configuring a number of antennas in an antenna array to use in communicating in a wireless network. The number of antennas of the antenna array, less than all available antennas for transmission or reception in the antenna array, can be determined such to achieve a radio frequency (RF) power that results in a certain effective data rate for communicating in the wireless network. The number of antennas can be indicated, over a backhaul, to one or more other access points of the wireless network to coordinate using of the number of antennas at a determined time. One or more devices in the wireless network can be communicated with using the number of antennas.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support power saving of wireless repeaters. Generally, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, etc.) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may operate in a power saving mode and monitor for control information from a base station according to a slow state (e.g., according to a relatively long monitoring periodicity). Upon detection of possible UE attachment to the base station (e.g., upon detection of a random access channel (RACH) message), the wireless repeater may transition to monitoring for control information from the base station according to a fast state (e.g., according to a relatively short, or more frequent, monitoring periodicity).

Abstract: Methods, systems, and devices for wireless communications are described in which multiple different wireless resource configurations for a multiple-hop wireless network may be configured and selected to provide for efficient updates to resource configurations. A central entity may configure one or more other nodes of the network with a number of different wireless resource configurations for backhaul communications among the other nodes. A first node may receive the number of different wireless resource configurations, identify wireless resources associated with a first resource configuration that are allocated for backhaul communications, and communicate with a second node using the allocated resources. In the event that the first node determines that a different wireless resource configuration should be used for communications with the second node, the first node may select a second resource configuration from the number of different wireless resource configurations for further communications with the second node.

Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support modem control using millimeter wave (mmW) energy measurement. Generally, the described techniques provide for wireless device (e.g., wireless repeater) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may perform relay operations (e.g., amplification and forwarding operations) for communications between a base station and a UE in some channel (e.g., in a mmW channel). The wireless repeater may use energy measurements in the channel (e.g., analog mmW measurements) to control or configure a digital interface for monitoring out of band control information (e.g., in a sub-6 gigahertz (GHz) channel). For example, a wireless repeater may use energy measurements of signals transmitted by devices in a mmW band to configure (e.g., turn on) a digital interface of another modem to monitor for control information in a sub-6 GHz band.
