Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may communicate according to a combined cyclic prefix and guard interval-based waveform format. The base station may transmit control signaling to the UE. The control signaling may indicate a slot configuration. The UE may identify a format of a slot including a set of symbols based on the slot configuration. The format may indicate that a first portion of a first symbol of the set of symbols includes at least two cyclic prefixes and a second portion of the first symbol includes a guard interval. The UE and the base station may perform wireless communications during the first symbol in accordance with the format.

Abstract: A non-terrestrial network is provided that includes a satellite that transmits an orbital parameter message to a user equipment. The user equipment processes the orbital parameter message to determine a current range from the user equipment to the satellite based upon the received orbital parameter message, a timing offset and a frequency offset for an uplink transmission to the satellite.

Abstract: Methods, systems, and devices for wireless communications are described. Devices in a wireless communications system may support different configurations to support intra-symbol multiplexing for communications between the devices using a single carrier waveform. For example, the different configurations may include symbol level cyclic prefixes, device-specific or channel-specific cyclic prefixes, device-specific or channel-specific guard intervals, or a combination thereof to support the intra-symbol multiplexing. That is, the cyclic prefixes or guard intervals may separate different fractions of a symbol, such that individual signals communicated in each of the different fractions do not leak into a subsequent fraction to cause interference. In some implementations, the cyclic prefixes or guard intervals may be enabled for a subset of devices or channels. A configuration for this intra-symbol multiplexing with device-specific or channel-specific cyclic prefixes or guard intervals may be signaled in a control message to the corresponding devices.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a base station may transmit, to a user equipment (UE), an indication of a dynamic switch between slot formats. The base station and the UE may communicate first data in one or more first slots according to a first slot format. The first slot format may be a first cyclic prefix-based or guard interval-based slot format. The base station may transmit control signaling to the UE to indicate a second slot format different from the first slot format. The second slot format may be a second cyclic prefix-based or guard interval-based slot format. The UE and the base station may switch to communicating second data in one or more second slots in accordance with the second slot format based on the control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first downlink control information (DCI) scheduling a downlink transmission at the UE, where the first DCI includes an indication of a first resource allocation for the downlink transmission. The UE may determine that the downlink transmission includes a downlink data message multiplexed with second DCI. The UE may receive an indication of a second resource allocation for the second DCI. The UE may determine a transport block size (TBS) of the downlink data message based on the first resource allocation for the downlink transmission and the second resource allocation for the second DCI. The UE may then process the downlink transmission based on the TBS of the downlink data message.

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: 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 identify a configuration for a set of bandwidth part groups including an intra-group switching delay and an inter-group switching delay, where the intra-group switching delay is smaller than the inter-group switching delay. The UE may communicate with a base station on a first bandwidth part of a first bandwidth part group of the set of bandwidth part groups. The UE may switch to a second bandwidth part of the first bandwidth part group based at least in part on the intra-group switching delay, or the UE may switch to a third bandwidth part of a second bandwidth part group based at least in part on the inter-group switching delay. The UE may communicate with the base station on the second bandwidth part or the third bandwidth part based on switching.

Abstract: In one aspect, an extended SSB (ESSB) is provided that includes more than four symbols to facilitate UE reception of SSBs. In this aspect, the base station configures an ESSB comprising an SSB including four symbols and an initial symbol preceding the SSB. The base station transmits and the UE receives at least a portion of the ESSB. The UE processes the ESSB. Thus, higher capacity UEs can benefit from additional coding gain in the initial symbol while lower capacity UEs can switch beams to receive back-to-back ESSBs. In another aspect, a UE performs additional behaviors to receive SSBs. In this aspect, the UE receives a first SSB using a reception beam, and the UE determines to maintain the reception beam for a second SSB or to switch the reception beam during a PSS symbol of the second SSB. Thus, lower capacity UEs can also receive back-to-back SSBs.
