Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a multicast or broadcast radio bearer (MRB) in a radio link control (RLC) acknowledged mode (AM). The UE may determine an adjustment of an RLC AM transmission window of a base station. The RLC AM transmission window may be associated with retransmission of RLC packets associated with the MRB. The UE may synchronize an RLC AM reception window of the UE with the RLC AM transmission window based at least in part on determining the adjustment of the RLC AM transmission window of the base station. The RLC AM reception window may be associated with reassembly of RLC packets associated with the MRB. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A serving base station or a serving satellite may transmit a timing configuration to the UE based on a reference unit, such as a location at a beam center for a respective satellite, a threshold distance relative to the beam center for the respective satellite, a reference time, or any combination thereof. In some cases, the UE may monitor for one or more SSBs from the neighboring satellites according to the timing configuration and a respective propagation delay between the UE and each of the neighboring satellites. The UE may measure the SSBs according to the measurement gap and measurement window in the timing configuration. In some examples, the UE may perform a cell handover procedure or a cell reselection procedure based on measuring the SSBs.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a message from a first non-terrestrial network cell indicating cell synchronization information for a second non-terrestrial network cell. In some examples, the cell synchronization information may indicate whether the first non-terrestrial network cell and the second non-terrestrial network cell are synchronized at a reference point. Additionally, or alternatively, the cell synchronization information may indicate a timing offset value between a first uplink time synchronization reference point of the first non-terrestrial network cell and a second uplink time synchronization reference point of the second non-terrestrial network cell. The UE may calculate a timing associated with signaling from the second non-terrestrial network cell based at least in part on the cell synchronization information. The UE may receive one or more signals from the second non-terrestrial network cell based at least in part on the calculated timing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may selectively determine to decode a downlink shared channel multicast transmission based on whether the downlink shared channel includes a retransmission of an initial multicast transmission. A base station may transmit a message in a downlink control channel to indicate if the downlink shared channel is carrying the retransmission of the initial multicast transmission. For example, the base station may transmit a group random network temporary identifier, downlink control information with a retransmission indicator bit, or both to indicate if the downlink shared channel is carrying the retransmission. In some cases, the message in the downlink control channel may be received at a layer one (L1) of the UE, and the downlink shared channel transmission may be decoded at L1 of the UE and sent to a layer two (L2) of the UE for processing.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a first cell. The UE may receive a request to report one or more parameters associated with handover from the first cell to a second cell during a time period. The one or more parameters may include an estimated propagation delay between the UE and the second cell during the time period, an estimated rate of change in propagation delay during the time period, or both. The UE may transmit a message indicating the parameters in response to the request. The UE may receive an indication of an uplink grant occasion associated with the handover during the time period based on indicating the parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a random access message (e.g., a message 3) associated with a random access procedure. A hybrid automatic repeat request (HARQ) feedback may be disabled for the random access procedure. The UE may initiate a contention resolution window associated with the random access procedure for a first downlink data channel transmission of a set of downlink data channel transmissions associated with the random access procedure. The UE may receive, during the contention resolution window, the first downlink data channel transmission carrying a contention resolution medium access control-control element (MAC-CE). The UE may transmit acknowledgment information for the first downlink data channel transmission carrying the contention resolution MAC-CE based on an indication to enable the HARQ feedback.

Abstract: Methods, systems, and devices for wireless communication are described to indicate a transmission scheme configuration for a message and whether the message is a retransmission or new transmission. In a first example, a base station may configure a subset of one or more feedback process identifiers (IDs) for multicast messages. In such cases, if a grant includes a feedback process ID associated with one of the reserved IDs, the message scheduled by the grant may be a retransmission of a multicast message. In a second example, feedback process IDs may be dynamically allocated to multicast or unicast messages via a corresponding grant. A message may be identified as a new transmission or retransmission of a unicast message or multicast message based on a combination of an ID associated with the grant and a new data indicator (NDI) of the grant.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of system information blocks (SIBs) common to a set of cells of a non-terrestrial network (NTN), the set of SIBs indicating one or more parameters common to the set of cells for communications with the set of cells. The UE may receive a first SIB associated with a first cell of the set of cells of the NTN, where the first SIB includes cell-specific information indicating a first set of cell-specific parameters for communications with the first cell. The UE may then communicate with the first cell using the first set of cell-specific parameters associated with the cell-specific information of the first cell and at least a first sub-set of parameters of the one or more parameters that are common to the set of cells.
