Abstract: Aspects relate to wireless communications utilizing cross carrier scheduling Methods and apparatus include generating at least one slot in a control channel from a scheduling cell, the at least one slot including a plurality of control channel segments such as PDCCH segments, which are arranged at respective times within the at least one slot. Each of the control channel segments includes control information such as DCIs corresponding to respective slots for a scheduled cell. Distributing the control channel information in segments or spans over time affords improved decoding timing in a UE in the scheduled cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as a user equipment (UE), may determine a capability relating to an antenna configuration associated with channel state information reporting. The UE may transmit a message including an indication of the capability, and receive a channel state information reference signal using the antenna configuration. The UE may transmit, based on the channel state information reference signal, a channel state information report in accordance with the antenna configuration associated with the channel state information reporting.

Abstract: Wireless communication devices, systems, and methods related to handling wake-up behavior for power saving, including during discontinuous reception (DRX) operation are provided. For example, a method of wireless communication can include receiving a default wake-up configuration associated with a discontinuous reception (DRX) operation; monitoring, during a wake-up signal (WUS) occasion, for a WUS; determining whether the WUS was received during the WUS occasion; and performing physical downlink control channel (PDCCH) monitoring based on the default wake-up configuration and whether the WUS was received during the WUS occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish communications with a first base station and a second base station in accordance with a dual connectivity configuration. The UE may determine a second uplink timing gap for communications with the second base station and determine, based on being in the dual connectivity configuration, a first uplink timing gap for communications with the first base station. The first uplink timing gap may be determined to be greater than the second uplink timing gap. The UE may communicate with the first base station based on the first uplink timing gap. The UE may also prioritize uplink transmit power determinations for the first base station over uplink transmit power determinations for the second base station.

Abstract: Methods, systems, and devices for wireless communications are described that provide for allocation of control channel candidates for multiple component carriers (CCs) in carrier aggregation (CA) communications. A CA limit may correspond to a total number of configurable control channel candidates across multiple CCs. The control channel candidates may include blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation. A per-CC limit of control channel candidates may correspond to a number of configurable control channel candidates for each CC. An applied set of control channel candidates may be determined by allocating control channel candidates across the multiple CCs based on the CA limit and the per-CC limit. Such techniques may be used in cases where the CCs have a same numerology or mixed numerology, and may also be used for cross-carrier scheduling.

Abstract: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. A mobile device receives a control signal having a first bandwidth. The mobile device receives a data signal having a second bandwidth different from the first bandwidth. The control signal and the data signal are received over a single carrier frequency. The data signal is transmitted after the control signal such that the data signal and control signal are separated by a time interval. The time interval is based on a switching latency of the mobile device.

Abstract: Certain aspects of the present disclosure relate generally to wireless communications systems, and more particularly, to techniques that may help reduce or eliminate ambiguity in acknowledging multiple physical downlink shared channel (PDSCH) transmissions in a single transmission time interval (TTI). According to aspects, a codebook with fewer fields than a number of PDSCH candidates may be used to provide acknowledgement/negative acknowledgement (ACK/NACK) feedback.
