Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently facilitating acknowledgment (ACK) or negative acknowledgment (NACK) feedback from a user equipment (UE) for a set of transport blocks in one or more multicast transmissions from a base station. The UE may determine control channel resources for transmitting the ACK/NACK feedback, and each respective control channel resource may correspond to a distinct subset of the set of transport blocks. Once the UE determines a subset of transport blocks that the UE failed to decode (such as at least one transport block), the UE may determine a respective control channel resource that corresponds to the at least one transport block that the UE failed to decode. The UE may transmit ACK/NACK feedback on the respective control channel resource, which, in some examples, may indicate that the UE failed to decode the subset of transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: A user equipment may be configured to perform cell reselection during a gateway or satellite switch. In some aspects, the user equipment may select a current cell of a satellite device in a radio access network (RAN) and receive, from the satellite device, cell reselection information for identifying a destination cell for selection in response to a link modification. Further, the user equipment may select, via a cell reselection process, the destination cell based on the cell reselection information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a radio resource control (RRC) reconfiguration message from a base station including a configuration for communicating with the base station, and the base station may transmit an RRC reconfiguration complete message to the base station (e.g., in response to the RRC reconfiguration message). The UE may then apply the configuration in the RRC reconfiguration message for communicating with the base station after transmitting the RRC reconfiguration complete message. That is, the UE may delay application of the configuration in the RRC reconfiguration message until after the UE transmits the RRC reconfiguration complete message. Using these techniques, ambiguity between the base station and the UE on when the configuration is applied by the UE may be minimized, resulting in improved throughput and reduced latency in a wireless communications system.

Abstract: Methods, systems, and devices for wireless communications are described in which repetitions of communications may be configured for multi-transport block (TB) communications. A UE may determine that an acknowledgment of one or more initial repetitions of one or more TBs is received, and may cancel one or more subsequent repetitions of the acknowledged TB(s). The acknowledgment of the one or more initial repetitions may be provided by a base station in a new resource grant that provides an implicit acknowledgment of one or more TBs. In cases where multiple different TBs may be associated with the prior resource grant, the UE can determine to drop one or more repetitions after an implicit acknowledgment of a TB based on whether the resource grants are for a single TB or are for multiple TBs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine an inactivity timer associated with a first set of one or more beams used for communicating with a network entity associated with a satellite has expired. The UE may identify location information corresponding to the location of the UE with respect to the network entity. The UE may identify beam geometry information for one or more beams associated with the network entity. For example, the UE may receive the beam geometry information from the network entity. The UE may process the location information and the beam geometry information to identify a second set of one or more beams, the second set different than the first set. The UE and the network entity may communicate according to the second set of one or more beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a position (e.g., a global navigation satellite system (GNSS)) position of the UE based on a relative position of the UE to another UE. For example, a first UE may determine (e.g., calculate, receive) a relative position of the first UE to a second UE that is selected from a set of UEs including the first UE and the second UE to perform a position acquisition procedure to determine a position of the second UE. The first UE may determine (e.g., calculate, receive) its position based on the relative position of the first UE to the second UE and the position of the second UE and may reset a timer that indicates for the first UE to perform a position acquisition procedure upon expiration of the timer.

Abstract: Methods, systems, and devices for radio link management are described. In a first example, a user equipment (UE) and a base station may employ a procedure for configuring radio link monitoring reference signals (RLM-RS) for multiple bandwidth parts. In a second example, a UE and a base station may employ a beam failure recovery procedure. In a third example, a UE and a base station may employ one or more radio link failure detection procedures. In a fourth example, a UE and a base station may employ a procedure for establishing a new connection after radio link failure. In a fifth example, a UE and a base station may employ a monitoring procedure that involves a single RLM-RS across multiple bandwidth parts.

Abstract: Certain aspects of the present disclosure provide techniques for finite field parity for a hybrid automatic repeat request (HARQ) codebook. A method that may be performed by a base station (BS) includes indicating, to a user equipment (UE), a codebook for uplink transmission of HARQ feedback, the codebook based on: (i) a number (M) of candidate downlink transmission occasions for a time period, and (ii) a maximum number (k) of downlink transmissions the UE can receive during the time period. The method also includes selecting an action to perform based on a set of codepoints of the codebook, the set of codepoints comprising: (i) a first combination of codepoints, and (ii) a second combination of codepoints different from the first combination, wherein HARQ feedback calculated from the first combination is equal to HARQ feedback calculated from the second combination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives one or more downlink signals using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, selects a set of frequency resources for transmitting feedback information associated with the one or more downlink signals, and transmits the feedback information to the base station using the selected set of frequency resources. In some examples, the UE transmits one or more uplink signals to a base station using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, and determines whether to send a retransmission of the one or more uplink signals based at least in part on switching.
