Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.

Abstract: A UE may be configured for half-duplex communications. An access point may configure half-duplex UEs for efficient resource utilization using two of more different half-duplex configurations that include different timing for channels in different directions. A UE may determine a half-duplex configuration for use in communicating with the access point, each slot of the half-duplex configuration including at least a PDCCH on a downlink frequency and an uplink short burst on an uplink frequency, and each slot associated with a HARQ timeline. The UE may determine a direction for a slot. The UE may transmit or receive according to the direction for the slot and the half-duplex configuration.

Abstract: A configuration to allow a UE to receive a BWP configuration that supports RC NR. The UE sends information to a network indicating a UE capability of the UE. The UE receives, based on the UE capability, information indicating a BWP associated with a first BWP, the second BWP having a frequency range equal to or less than the first BWP. The UE receives at least one of control information or data based on the indicated first BWP and the second BWP.

Abstract: Aspects of the present disclosure provide various flexible search space designs that can handle UEs with various capabilities and limitations. In some aspects of the disclosure, the downlink bandwidth may be divided into several self-contained sub-bands. Each sub-band may include one or more OFDM subcarriers or tones, and each UE may be configured to monitor one or more of the sub-bands for its downlink control channel. The sub-band is self-contained in such a way that each sub-band includes CCEs that are mapped to resource elements contained in the same sub-band. In some aspects of the disclosure, different sub-bands can be configured with the different transmission modes and pilot densities. The transmission mode, pilot density, and layer-ID may be determined as a function of each UE's search space.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The method generally includes receiving, from a network entity, signaling indicating a transmission configuration indictor (TCI) state, determining a default quasi-co location (QCL) parameter based on the TCI state for communication via a first cell of a cross-carrier scheduling protocol, and communicating with the network entity based on the default QCL parameter.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a base station (BS) obtains an indication that downlink transmissions to a first user equipment (UE) potentially interfere with uplink transmissions by a second UE, the BS dynamically allocates, based on the indication, a first set of one or more resource blocks (RBs) for the downlink transmissions to the first UE, and the BS then transmits an indication of the first set of RBs to the first UE. Other aspects, embodiments, and features are also claimed and described.

Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power settings for different parameters that impact the amount of power consumed by the UE. Such transitions may be configured to occur during a discontinuous reception (DRX) active time to provide power savings during the DRX active time or increase throughput during the DRX active time. In some aspects, the transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput (e.g., when data is available for the UE), and which may assist with extending battery life of the UE (e.g., when data is not available for the UE). In some aspects, such transitions and associated parameter values may be preconfigured or a transition may be triggered by expiration of a timer, thereby reducing signaling overhead.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive an indication of a bandwidth part (BWP) switch for a secondary cell and to transition between an active state and a dormant state for the secondary cell based on the indication of the BWP switch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify a scheduling window associated with acquiring a system information message, wherein the scheduling window is based at least in part on control channel monitoring occasions associated with a control channel, wherein the control channel is to schedule a data channel that includes the system information message; and receive the control channel based at least in part on the scheduling window, wherein the control channel is received within the scheduling window. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of connected discontinuous reception (C-DRX) by using a wireless device (e.g., a user equipment (UE)) with a second receiver. A wireless device with two receivers may place one receiver in a low power mode and take the receiver out of the low power mode in response to a signal received from a serving base station (BS) of the wireless device. A BS may direct a wireless device to enter a low power DRX (LP-DRX) mode or enhanced DRX mode having longer low power cycles than a non-enhanced DRX mode, and the wireless device may place a primary receiver in a low power mode in response to the directive from the BS. Other aspects, embodiments, and features are also claimed and disclosed.
