Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of control resource sets for reduced bandwidths. In a first aspect, a method of wireless communication includes receiving, from a base station at a user equipment (UE) having a first type, a master information block (MIB) within a physical broadcast channel (PBCH). The MIB includes CORESET size information and search space information for devices having a second type. The method also includes selecting a CORESET size from a plurality of preconfigured CORESET sizes based on a subcarrier spacing used to communicate with the base station. The method further includes monitoring a set of time and frequency resources to receive a message from the base station. The set of time and frequency resources has the selected CORESET size. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described for user equipment (UE) indication of uplink scheduling information to a base station. The uplink scheduling information may provide information on a periodic traffic pattern, such as for periodic extended reality (XR) data flows. The uplink scheduling information may provide uplink assistance information (UAI) to a base station to assist the base station with providing uplink resources that efficiently serve an XR session. The UAI may indicate one or more of a periodicity of uplink traffic, an offset between uplink traffic and a packet arrival, a data size for uplink traffic for each time period associated with the XR session, a request to enable uplink transmission skipping, or any combinations thereof. A base station may provide one or more dynamic grants, configured grants, or proactive grants to a UE based on the uplink scheduling information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a base station, before a next paging occasion (PO) of a paging cycle, a page indication (PI) in a first PI location associated with the next PO, wherein the PI comprises at least one repetition of a plurality of repetitions of the PI transmitted in the first PI location on each of a plurality of beams, and decodes the PI to determine whether or not the UE is paged in the next PO.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message scheduling a first message and including an indication that the first message is scheduled for full-duplex operation with a second message. The indication may be a DCI field configured for indicating full-duplexing, or the DCI field may be an existing DCI field configured to also indicate full-duplexing. The UE may identify a set of parameters associated with the full-duplex operation of the first message based on receiving the DCI message that includes the indication, and the UE may communicate the first message using the set of parameters associated with the full-duplex operation and based on the indication included in the DCI message.

Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine a grant for performing uplink transmissions based on a radio resource control (RRC) message. The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.
