Abstract: This disclosure provides systems, methods, and devices for wireless communication that support allocation of resources for a physical broadcast channel (PBCH) for reduced bandwidth devices. In a first aspect, a method includes monitoring, by a user equipment (UE) configured for reduced bandwidth operation, at least a subset of a first set of time and frequency resources allocated to a synchronization signal block (SSB) for UEs configured for non-reduced bandwidth operation. The SSB includes synchronization signals and a PBCH. The method includes monitoring, by the UE, a second set of time and frequency resources allocated to the PBCH for UEs configured for reduced bandwidth operation. The method includes receiving, by the UE, the synchronization signals and the PBCH within at least the subset of the first set of time and frequency resources and the second set of time and frequency resources. Other aspects and features are also claimed and described.

Abstract: Aspects enable and provide techniques for sidelink communication resource configuration and management. A first user equipment (UE) negotiates with a second UE to select a first communication resource set (ComReSet) from a plurality of ComReSets for sidelink communication. Each of the plurality of ComReSets has a corresponding periodicity of one or more hyper-frames. The first UE communicates with the second UE using the first ComReSet using a frame timing synchronized with the corresponding periodicity of the first ComReSet.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of more than three orthogonal frequency division multiplexing (OFDM) symbols in the time domain to a control resource set (CORESET). In a first aspect, a method for wireless communication includes receiving, from a base station at a user equipment (UE), a first message that indicates a CORESET configuration. The CORESET configuration allocates more than three OFDM symbols in the time domain to a CORESET. The method further includes monitoring a set of time and frequency resources to receive a second message from the base station at the UE. The set of time and frequency resources have the CORESET configuration. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support inter-slot bundling and frequency hopping. In a first aspect, a method of wireless communication includes receiving a message indicating inter-slot bundling for uplink channel inter-bandwidth part (BWP) frequency hopping repetitions. The method also includes receiving bundling information and redundancy value (RV) information for an uplink channel transmission and corresponding uplink channel transmission repetitions. The method includes transmitting the uplink channel transmission with inter-slot bundling and frequency hopping and based on the bundling information and the RV information. The method further include transmitting an uplink channel transmission repetition of the uplink channel transmission with inter-slot bundling and frequency hopping and based on the bundling information and the RV information. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, information via a sidelink interface between the first UE and the second UE. The UE may transmit, to the second UE, sidelink hybrid automatic repeat request acknowledgement feedback using a sidelink feedback channel resource of a sidelink resource pool via a sidelink component carrier based at least in part on the information received from the second UE. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a timing advance (TA) command indicating partial TA compensation, start a TA timer for partial TA compensation for full duplex based at least in part on receiving the TA command, and perform a synchronization procedure based at least in part on expiration of the TA timer for partial TA compensation for full duplex. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station of a wireless communications system may transmit, to a user equipment (UE), a configuration message that indicates a transmission time interval (TTI) format for a plurality of TTIs. At least one format for the plurality of TTIs includes uplink resources and downlink resources separated in the frequency domain, which may be an example of a subband full duplex (SBFD) slot. Since the pattern may include some transitions between uplink and downlink resources, one or more gap periods (e.g., time gaps) may be positioned between such resources.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a receiver. The apparatus is configured to receive a non- coherent signal and determine a first differential of the received non-coherent signal on each of one or more receive antennas for a set of binary vectors to obtain a lower order representation of the non-coherent signal. The apparatus is configured to combine the differentials across antennas, decode the lower order representation of the non-coherent signal based on the first differential of the non-coherent signal and to reconstruct a higher order representation of the non-coherent signal based on the decoded lower order representation of the non-coherent signal.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication of a transmission power for a synchronization signal block (SSB) transmission by a base station, the indicated transmission power different than a default transmission power for SSB transmissions by the base station. The UE may determine a received power with which the SSB transmission is received at the UE. The UE may receive one or more downlink transmissions from the base station based at least in part on the received power for the SSB transmission and a difference between the default transmission power and the indicated transmission power for the SSB transmission.
