Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station by initiating a random access procedure with a multi-root preamble. The UE may receive, from the base station, a configuration message that indicates one or more parameters for the multi-root preamble. The one or more parameters may include cyclic shifts, phase rotations, and sequence roots corresponding to a plurality of sequences. The base station may identify the one or more parameters and transmit the configuration message based on the identifying. The UE may identify the one or more parameters for the multi-root preamble based on the configuration message and/or a pre-configuration at the UE. The UE may transmit, to the base station, the multi-root preamble based at least in part on the one or more parameters.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to determine a time gap between receiving a paging early indication (PEI) and receiving a paging message based on a link quality of the UE. The UE may determine the time gap based on a number of reference signals the UE may measure after receiving the PEI to obtain channel information for accurately decoding a forthcoming paging message and a periodicity of the reference signals. The UE may transmit UE assistance information (UAI) to the base station during an active state to indicate the time gap. The UE may receive a configuration message from the base station indicating a configured time gap for the UE based on the UAI. The UE may receive the PEI and monitor a paging occasion for the paging message according to the configured time gap.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling from a base station that includes an indication of a configuration for measuring cross-link interference (CLI) and an indication of a reference subcarrier spacing (SCS). The configuration may be associated with a slot having more than 14 symbols and may indicate a resource allocation that includes a sounding reference signal (SRS) resource, a CLI resource, or both. The UE may use the SRS resource to measure an SRS and may use the CLI resource to measure a received signal strength indicator (RSSI). The UE may measure the SRS and the RSSI according to the reference SCS. The UE may determine a CLI level based on measuring the SRS, the RSSI, or both. The UE may transmit, to the base station, a report including an indication of the determined CLI level.

Abstract: Methods, systems, and devices for wireless communication are described to support allocation of a group-based configured uplink resource for idle mode uplink transmissions. User equipments (UEs) may be grouped geographically and/or functionally and may have sidelink communications among themselves, and may be in an inactive mode or an idle mode. A base station may allocation one or multiple configured uplink resources to the group of UEs, where the base station may be aware of the group based on signaling from a UE of the group. The group of UEs may determine which UE of the group may use the allocated resources, and in which occasions. Based on the determination, one or more UEs of the group may transmit an uplink message to the base station using the configured uplink resource assigned to the group.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a user equipment (UE) with a frequency resource for a multicast/broadcast service (MBS) for the UE to monitor for one or more group-common downlink control channels. The base station may transmit an indication, such as an explicit indication, of a monitoring condition for the group-common downlink control channels within the frequency resource. The UE may apply the monitoring condition by enabling or disabling the group-common downlink control channel monitoring within the frequency resource. The UE may monitor one or more downlink control channels for scheduling information from the base station according to the monitoring condition.

Abstract: A method, base station (BS), user equipment (UE), apparatus, and computer program product for wireless communication are provided. An aggressor BS may cause a remote interference condition for a victim BS, and the victim BS may transmit a reference signal to the aggressor BS to enable a remote interference management (RIM) operation to be performed. However, the aggressor BS may be unable to identify the victim BS based at least in part on the reference signal, and may fail to transmit a reference signal as a response. Further, when the aggressor BS does transmit a reference signal, the victim BS may be unable to identify the aggressor BS. This may reduce an effectiveness of RIM operations. In some aspects, BSs may transmit reciprocal reference signals including identification information to enable effective RIM operations.

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.
