Abstract: Methods, systems, and devices for wireless communications are described. A downlink shared channel scheduling delay and an acknowledgment feedback delay may be jointly encoded and sent to a user equipment (UE). For example, a downlink control information (DCI) field may jointly indicate the downlink shared channel scheduling delay and the acknowledgment feedback delay in a field of ‘X’ bits, where ‘X’ is configurable by a base station (e.g., via radio resource control (RRC) signaling). Subsequently, the UE may then determine the downlink shared channel scheduling delay and the acknowledgment feedback delay from the DCI by using respective equations based on a value from the jointly encoded indication or by using a table based on the value from the jointly encoded indication. Additionally, the downlink shared channel scheduling delay and the acknowledgment feedback delay may be expressed in terms of absolute subframes, invalid/valid subframes, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A network node and a user equipment (UE) may establish a connection between the UE and the network node of a non-terrestrial network. The UE may receive, from the network node and based on a type of orbit around Earth of the network node, a first value or the first value and a second value associated with a position or a velocity of the network node relative to a terrestrial-based reference. The UE and the network node may communicate based on the position or the velocity of the network node, or both. In some cases, the position or the velocity of the network node is based on an altitude of the network node, the first value, the second value, and a third value.

Abstract: According to the present disclosure, CSI and/or a plurality of ACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. Once the trigger is received, the UE may transmit the CSI and/or GACK to the eNB. In this way HARQ feedback and/or CSI may be reliably communicated while reducing payload. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus send, to a UE, data transmissions associated with a first plurality of downlink subframes. In an aspect, the apparatus increments a counter for each data transmission sent to the UE. In a further aspect, the apparatus transmits, to the UE, a first trigger for a first GACK when a counter is greater than or equal to a threshold.

Abstract: Methods, systems, and devices for wireless communications are described that support multiplexing multicast and unicast feedback. A base station may provision different subsets of resources from a set of resources for multicast feedback message transmission based on channel metric(s) of a user equipment (UE). The set of resources may include a plurality of subsets of resources, with each subset of resources being associated with a corresponding channel metric or range of channel metrics associated with each UE receiving the multicast transmission. A UE may determine that a feedback indication is to be provided in response to the multicast transmission, and select a subset of resources from the plurality of subsets of resources based on its own channel metric. The UE may multiplex the multicast feedback, an indication of the selected subset, and unicast feedback in a multiplexed feedback transmission to the base station.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing cross-carrier scheduling. In one aspect, a processor of a wireless device may determine whether downlink control information (DCI) received from a secondary cell schedules communications on a primary cell, and may determine cross-carrier scheduling of communications on the primary cell in response to determining that the DCI received from the secondary cell schedules communications on the primary cell. In another aspect, processor of a network device may schedule communications on the primary cell in the DCI of the secondary cell, and may perform cross-carrier scheduling of communications on the primary cell based on the DCI of the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include establishing a connection between the UE and a network node of a non-terrestrial network, identifying, based on a synchronization failure event and while the UE is in a connected mode in accordance with establishing the connection, that a location failure condition has occurred for the connection, and performing, at least in part in response to the location failure condition, one or more actions of a location failure recovery procedure to restore a synchronization associated with the connection.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may activate or release one or more semi-persistent scheduling (SPS) configurations for group-common downlink shared channels based on signaling from a base station. For example, the UE may receive downlink control information (DCI) from the base station that includes a feedback process field, where a value of the feedback process field indicates at least one of one or more SPS configurations is to be activated. In some examples, the base station may transmit the DCI in a group-common downlink control channel or in a UE-specific downlink control channel. Additionally, the base station may transmit a deactivation message to the UE to indicate for the UE to release one or more activated SPS configurations, where the deactivation message is transmitted in a group-common downlink control channel or a UE-specific downlink control channel.

Abstract: A method, an apparatus, a base station, a user equipment (UE), and a computer program product for wireless communication are provided. The base station may encode a wakeup signal so that a preamble of the wakeup signal indicates whether the wakeup signal is relevant to the UE. The UE may select a technique for detecting the wakeup signal based at least in part on a partial, full, or no synchronization. In some aspects, the wakeup signal may be encoded with a system frame number. In some aspects, wakeup signals for guardband/standalone UEs are provided. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station (BS), an indication that the UE is to perform a conditional handover from the source BS to a target BS and is to perform at least one of: a two protocol stack handover from the source BS to the target BS or a dual connectivity handover from the source BS to the target BS. The UE may perform the conditional handover and at least one of the two protocol stack handover or the dual connectivity handover based at least in part on the indication. Numerous other aspects are provided.
