Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for an orthogonal frequency division (OFDM) symbol that includes one or more cell-specific reference signal (CRS) resource elements and one or more narrowband physical downlink shared channel (NPDSCH) resource elements, an NPDSCH energy per resource element (EPRE), wherein the NPDSCH EPRE for the OFDM symbol is based at least in part on an EPRE differential between a narrowband reference signal (NRS) EPRE and a CRS EPRE. The UE may demodulate the OFDM symbol based at least in part on the NPDSCH EPRE. 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 determine a reference time for updating one or more system information parameters associated with a non-terrestrial network (NTN) or updating a cell status associated with the NTN. The UE may determine an update timer length for updating the one or more system information parameters associated with the NTN or the cell status associated with the NTN. The UE may acquire, from a current cell or a new cell, a system information block (SIB) to refresh the one or more system information parameters after an expiration time associated with the one or more system information parameters, wherein the expiration time is based at least in part on the reference time and the update timer length. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for enhancing ephemeris for non-terrestrial networks. For example, UEs of different orbit propagation capabilities (e.g., computing orbit propagation models of different accuracy levels) may receive additional ephemeris parameters. In one aspect, a network entity may determine at least one additional set of ephemeris parameters that includes different ephemeris parameters than one or more basic sets of ephemeris parameters associated with a satellite that provides a coverage for the network entity. The network entity may transmit broadcast signaling indicating the at least one additional set of ephemeris parameters. The UE may receive and use the at least one additional set of ephemeris parameters in an orbit propagation model to compute a state of motion of the satellite.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine a polarization associated with a channel state information reference signal (CSI-RS) resource set configuration. The base station may transmit, to a user equipment, a polarization indication that indicates the polarization associated with the CSI-RS resource set configuration. 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 an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Transport blocks may be scheduled using a single downlink control information (DCI) message. A wireless device may identify mapping pattern for mapping the transport blocks and repetitions of the transport blocks to communication resources. Mapping the transport blocks, or determining a mapping of the transport blocks, to communication resources may include partitioning the communication resources into subunits, where each subunit includes resources spread across each subband of a frequency hopping pattern and at least one instance of each of the scheduled transport blocks.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first synchronization signal for synchronizing with a cell, the first synchronization signal transmitted at a first periodicity by a base station serving the cell. The UE may then receive, subsequent to the synchronizing, a second synchronization signal for resynchronizing with the cell. In some cases, the second synchronization signal may be transmitted by the base station according to a second periodicity that is different from the first periodicity. In some cases, the second synchronization signal may include a plurality of repetitions of a first sequence that is based at least in part on a cell identifier of the cell. The UE may communicate over the cell with the base station based at least in part on the resynchronizing.

Abstract: Methods, systems, and devices for wireless communications are described. A set of reference signal resources that are configured for sounding reference signal transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of reference signal resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel and transmit sounding reference signals over one of the shared reference signal resources that is associated with the set of channel state information determined by the UE. A base station that receives the sounding reference signal may transmit a subsequent multicast transmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied sounding reference signal resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more retransmissions of an initial group-common transmission. The UE may receive, in accordance with a first SPS configuration, a group-common transmission of a group-common downlink shared channel, the group-common transmission being associated with a first RNTI. The UE may transmit feedback information for the group-common transmission. The UE may then receive a downlink control information (DCI) message scheduling either a group-common retransmission of the group-common downlink shared channel or a unicast retransmission of the group-common downlink shared channel. The DCI may indicate that either the group-common retransmission is associated with the first RNTI or that the unicast retransmission is associated with a second RNTI that may be different from the first RNTI.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites or base stations, or both in a non-terrestrial network. Due to large distances between transmitting devices and receiving devices in a non-terrestrial network, the UE may account for propagation delay and frequency shift of communications with a satellite based on location information of the satellite. The UE may receive first satellite location information from a base station or a satellite, via a broadcast message. The UE may receive second satellite location information from the wireless network node via a unicast message, where both the first satellite location information and the second satellite location information relate to a same satellite. The UE may transmit an uplink communication via the satellite based on at least one of the first satellite location information or the second satellite location information.
