Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may receive, from a source node, an access request message using a first carrier, wherein the first carrier is to be used for routing decision traffic by each wireless node of a cluster of wireless nodes of the wireless multi-hop network, wherein the cluster includes the wireless node and the source node; and transmit, to the source node, an access response message using the first carrier, wherein the access response message indicates a selected routing option, of a set of routing options, for the source node to use to transmit a data communication to the wireless node using a second carrier. Numerous other aspects are provided.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for data aided receivers for URLLC. With more specificity, a UE may encode and modulate at least one of control information or data from a first code block received through a first channel from a base station to obtain an encoded and modulated reference first code block. A comparison between the reference first code block and the first code block may be performed by the UE to estimate a second channel for receiving a second code block from the base station. After receiving the second code block from the base station, the UE may demodulate and decode the second code block based on the second channel that was estimated via the comparison of the reference first code block to the first code block.

Abstract: A transmitting device maps complex valued symbols in sequence to physical resource blocks for a sidelink transmission. The transmitting device reserves a first symbol of a subframe, where resource elements in the first symbol of the subframe are not considered in mapping the complex valued symbols to the physical resource blocks for the sidelink transmission. The transmitting device transmits the sidelink transmission after mapping the complex valued symbols to the physical resource blocks. A receiving device receives the sidelink transmission and decodes the sidelink transmission to determine complex valued symbols that are mapped in sequence to physical resource blocks of the sidelink transmission, where the complex valued symbols are not mapped to resource elements in a first symbol of a subframe.

Abstract: Method and apparatus are provided for power saving by detecting empty symbols. In accordance with some implementation, a UE may determine that a data channel is not allocated to it by determining that there is no beam directed to it and there was no prior resource allocation to it. The UE upon such determination may enter sleep mode until the start of the next scheduling unit. This may result in reduction in power consumption compared to entering sleep mode after demodulating and decoding the control channel.

Abstract: In order to enable asynchronous, autonomous reception beam switching at a UE while minimizing degradation due to a transient in link performance, a method, apparatus, and computer-readable medium for wireless communication are provided. The apparatus receives CSI-RS on different reception beams in different symbols, wherein one reception beam being a current serving reception beam, and determines whether to switch to a different reception beam based on a SPEFF metric for the different reception beam and/or a severity of a potential link transient qualified in terms of the expected CQI/MCS degradation in the channel. The apparatus may switch from a current serving reception beam to a second reception beam when a first channel quality for the current serving reception beam is within a threshold value of a second channel quality for the second reception beam, the second channel quality being measured using a current configuration.

Abstract: Certain aspects of the disclosure provide techniques for a user equipment (UE) to determine a receive beam of a plurality of receive beams for receiving an upcoming transmission from a base station, wherein the determining is based on whether an indication is received from the base station indicating if the upcoming transmission includes a reference signal (RS) multiplexed with additional data. The techniques further provide for the UE to receive the upcoming transmission using the determined receive beam.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to receive a plurality of beams through a plurality of different receive beam directions, each of the beams including broadcast information on a PBCH. The apparatus may be further configured to determine, for each of a subset of the received beams, a log likelihood ratio (LLR) for coded bits of the broadcast information. The apparatus may be further configured to decode the broadcast information associated with each of the subset of the received beams, and determine a refined receive beam direction based on the determined LLRs and based on whether the broadcast information associated with each of the subset of the received beams fails to decode or is successfully decoded.
