Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a first system information message including an indication of a resource configuration for a control resource set (CORESET) from a base station. The CORESET may include a common search space for a downlink control information (DCI) message that schedules a second system information message. The UE may identify a set of parameters from multiple sets of parameters for the CORESET based on the indication received in the first system information message and the UE being a first type of UE. The set of parameters may be different from a second set of parameters for the CORESET associated with a second type of UE different from the first type of UE. The UE may receive, in the CORESET according to the identified set of parameters, the DCI message scheduling the second system information message.

Abstract: Generating, by a user equipment (UE) of a wireless access network, for a set of contention-based random access occasions of a base station of the network, a random number over an interval. For the generated random number meeting a threshold value within the interval, transmitting, by the UE and to the base station, a random access preamble within one of the random access occasions of the set. For the generated random number not meeting the threshold value, attempting, by the UE, contention-based access to the network within a subsequent set of random access occasions of the base station, the subsequent set of random access occasions occurring after the set of contention-based random access occasions of the base station.

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: 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: 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: 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.
