Abstract: Methods, systems, and devices for wireless communications are described that provide for partitioning of time-frequency resources for access and backhaul links separately. A centralized scheduler in a centralized system or a set of access nodes (ANs) in a distributed system may allocate a portion of a set of resources for a given link type (e.g., access or backhaul). In some cases, multiple ANs may exchange reports or measurements to determine the resources to allocate to a given link type. The allocated resources may be repurposed for use by a different link type (e.g., access resources may be repurposed and used for backhaul resources) in order to account for varying traffic conditions.

Abstract: Methods, systems, and devices for wireless communication are described. Synchronization signals may be transmitted using a set of phase offsets over different component carriers or using a single component carrier for each antenna port. For example, a base station may identify a set of synchronization signals (e.g., a set of primary synchronization signals (PSSs)) to be transmitted over one or multiple component carriers. In some cases, each PSS may be associated with a different component carrier, and the base station may apply a different phase offset to each PSS when transmitting the set of PSSs on the component carriers. In some examples, the base station may transmit the PSSs on the component carriers using a different antenna port for each component carrier.

Abstract: Methods, systems, and devices are described for signaling protocols for proximity service functions in a wireless communication system. A first wireless device may identify a wireless relay requirement associated with the first wireless device. A proximity service protocol may be initiated between the first wireless device and a second wireless device based at least in part on the identified wireless relay requirement. The proximity service protocol may be initiated prior to an initiation of a communication data exchange between the first wireless device and the second wireless device. A relay link may be established, via the ProSe protocol, between the first wireless device and the second wireless device based at least in part on the identified wireless relay requirement.

Abstract: Certain aspects of the present disclosure provide techniques for performing, by a user equipment (UE), radio link monitoring based on discontinuous reception mode operation of the UE. Certain aspects provide a method for wireless communication. The method generally includes operating, at a user equipment (UE), in a discontinuous reception (DRX) mode of operation. The method further includes evaluating, by the UE, link quality between the UE and a base station (BS) at least once every time period, wherein the time period is based on a length of a DRX cycle of the UE operating in the DRX mode of operation and a reference signal (RS) period, wherein the BS is configured to transmit RS periodically every RS period.

Abstract: Methods, systems, and devices for random access channel (RACH) timing in a wireless communication are described. A base station and a user equipment (UE) may perform a RACH procedure to establish a communication link between the base station the UE. The RACH timing associated with the RACH procedure may depend on the numerology used for the RACH procedure and may be conveyed by the base station to the UE in a control message or via system information. In some cases, the numerology may indicate the RACH timing, which may be used to determine a number of symbols or absolute time to be used for portions of the RACH procedure.

Abstract: A network node of a communication network may determine that a target transmission power for a subsequent transmission by the network node is no longer optimal. In response to the determination, the network node may autonomously modify one or more parameters of the subsequent transmission, from a modulation and coding scheme (MCS) and/or a set resources for the subsequent transmission. The network node may then transmit a channel, based at least in part on the one or more modified parameters, to a target network node in the subsequent transmission. The target network node may determine that the network node has autonomously modified the one or more parameters of the transmission, from the modulation and coding scheme (MCS) and/or the set resources for the transmission. The target network node may process the transmission based on the determination.

Abstract: Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink grant that does not include a downlink assignment index (DAI); determine a pre-defined bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the pre-defined bundle window. In some aspects, a UE may receive a downlink grant that does not include a DAI; determine a bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI, wherein the bundle window is not pre-defined; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the bundle window. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for multiplexing new radio (NR) synchronization signals and paging signals. A Base Station (BS) decides whether or not to multiplex paging and synchronization signals in a set of time resources, a set of frequency resources or a combination thereof, the deciding based on at least one of a capability of the BS, a capability of at least one User Equipment (UE) served by the BS, an operating frequency band or a combination of tone spacings of the paging signals and the synchronization signals.

Abstract: The disclosure relates in some aspects to dynamically reserving a channel for performing connection setup and/or communicating high priority messages. RTS-CTS resources may be statically associated with different functions and different priorities. The highest priority RTS-CTS resource (or one of the highest priority RTS-CTS resources) may be used to set up connections between devices and/or communicate high priority messages between devices.

Abstract: Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.
