Abstract: Various designs for reference signals for beam management (BM) in non-terrestrial networks (NTNs) in 5G systems are discussed. NTN platforms determine to transmit a BM reference signal associated with a beam in an NTN. The BM reference signal is configured to facilitate beam switching at a wireless communication entity, and the beam having a beam bandwidth. The NTN platforms determines a frequency resource for transmitting the BM reference signal, and transmits, to a wireless communication entity, the BM reference signal in the determined frequency resource. The wireless communication entity monitors the frequency resource, receives the BM reference signal associated with the beam in the frequency resource, and manages beam selection based on the received BM reference signal. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit uplink transmissions according to a frequency hopping pattern. The UE may identify that a first set of uplink transmissions are to be transmitted to a base station by a first set of resources (e.g., a first set of slots, a first set of frequency resources) as indicated by the frequency hopping pattern. The UE may further identify, based on the frequency hopping pattern, that a second set of uplink transmissions are to be transmitted to the base station by a second set of resources (e.g., a second set of slots, a second set of frequency resources). The first set of slots and the second set of slots may each include more than one slot. Additionally, the first and second set of resources may be within a same bandwidth part or in different bandwidth parts.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor synchronization signal resources, each synchronization signal resources associated with a beam, and may select a preferred beam based on the monitoring. The UE may transmit an uplink random access message (e.g., message 3 of a four-step random access message, message A of a two-step random access procedure, or a negative acknowledgement (NACK) message requesting retransmission of a random access message) including beam information (e.g., one or more beam indices, channel quality information, or channel state information) to a base station. In response, the base station may transmit a downlink random access message using a different beam (e.g., a new preferred beam). The UE may establish a connection with the base station based on the completed random access procedure.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor multiple synchronization signal resources, each synchronization signal resource associated with a beam of a set of beams and may determine that multiple candidate beams of the set of beams satisfy a channel quality threshold. The UE may transmit an indication that the multiple candidate beams satisfy the channel quality threshold. For example, the UE may transmit a single random access message on a physical random access channel (PRACH) resource associated with multiple candidate beams, or may transmit multiple random access messages, each one on a different PRACH resource associated with a different candidate beam. The UE may receive an indication of one of the candidate beams from the base station and may establish a connection with the base station using the indicated candidate beam.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information (DCI) messages scheduling downlink data transmissions at the UE, where at least one DCI message schedules two or more downlink data transmissions. The UE may determine, based on the DCI messages, a first set of downlink resources associated with a first control resource set (CORESET) group and a second set of downlink resources associated with a second CORESET group. The UE may receive one or more first downlink data transmissions on the first set of downlink resources and one or more second downlink data transmissions on the second set of downlink resources. The UE may communicate using a first set of parameters associated with the first CORESET group and a second set of parameters associated with the second CORESET group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive system information associated with a set of neighboring cells included in a non-terrestrial network (NTN). The UE may be connected to or camped in a current cell included in the NTN. The current cell may be associated with a current platform.

Abstract: Methods, systems, and devices for wireless communications are described. A bandwidth part (BWP) configuration may be identified for a user equipment (UE), where the BWP configuration is part of a shared radio frequency spectrum band. In some cases, a base station may transmit a resource configuration for the BWP to the UE that indicates a set of subbands for the BWP and an indication of which subbands are available for the resource contention and possible subsequent communications. The UE and base station may determine a set of time-frequency resources for at least one downlink signal to be transmitted from the base station to the UE based on the BWP and available subbands. In some cases, the resource configurations for the BWP may include a reference signal configuration, a semi-persistent scheduling configuration, a control resource set configuration, or a combination thereof for the available subbands of the BWP.

Abstract: In one aspect, an apparatus configured for wireless communication includes at least one processor; and a memory coupled to the at least one processor. The at least one processor is configured to receive a control message indicating a reference signal offset information element (IE) for aperiodic reference signal offset determination and to receive a control channel transmission indicating a particular aperiodic reference signal transmission. The at least one processor is further configured to receive the particular aperiodic reference signal transmission based on a particular reference signal offset. The particular reference signal offset is determined based on the control channel transmission and a set of reference signal offset values, which are determined based on the reference signal offset IE and on one or more minimum scheduling conditions for cross-slot scheduling. Other aspects and features are also claimed and described.
