Certain aspects of the present disclosure provide techniques for paging early indication (PEI) configuration and monitoring procedures. In particular, the present disclosure provides techniques for configuring a user equipment (UE) for PEI monitoring. A method that may be performed by a network entity generally includes transmitting, to the UE, a configuration for paging early indication (PEI) occasions for the UE to monitor and transmitting, in at least one of the PEI occasions, a physical downlink control channel (PDCCH) with a PEI that indicates, for multiple paging occasions (POs), whether paging messages are scheduled for the UE in the multiple POs.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging early indication (PEI) physical downlink control channel communication with tracking reference signal (TRS) availability information at a location that is based at least in part on a length of a bitmap to be used for indicating a PEI. The UE may receive a TRS if the TRS availability information indicates that the TRS is to be transmitted. Numerous other aspects are described.

According to some embodiments, a method performed by a wireless device for receiving paging occasions and synchronization signals in a carrier frequency band comprises obtaining a first paging occasion configuration and a first synchronization signal configuration and determining that a paging occasion specified by the first paging occasion configuration at least partially overlaps in time with a synchronization signal specified by the first synchronization signal configuration. The method further comprises modifying at least one of the paging occasion configuration for the overlapping paging occasion and the synchronization signal configuration for the overlapping synchronization signal to frequency multiplex the paging occasion and the synchronization signal. The method further comprises receiving the paging occasion and the synchronization signal according to the at least one of the modified paging occasion configuration and modified synchronization signal configuration.

This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for determining a transmit power of a paging early indication (PEI) transmission. In particular, a user equipment (UE) receives a PEI from a base station indicating whether the UE is being paged during a paging occasion. The UE determines a transmit power of the PEI transmission. In some aspects, the UE determines the transmit power of the PEI transmission based on a configuration of the PEI provided to the UE, which may include an indication of the PEI transmission power as an absolute power value and/or a power offset value with respect to another transmission, signal, or channel. In some aspects, the transmit power of the PEI transmission is based on whether the PEI transmission is a beamformed transmission.

The method of wireless communication may include a UE, a base station, and a core network including an AMF. The UE may initiate an update of the paging subgroup ID assigned to the UE by transmitting paging assistance information to the AMF. The paging assistance information may include an expected paging probability of the UE. The base station may initiate an update of the paging subgroup ID assigned to the UE based on the change of RRC connection between the UE and the base station. The core network including the AMF may transmit an updated paging subgroup ID to the UE. The core network including the AMF may configure a set of candidate subgroups associated with the UE, and the base station may update the paging subgroup ID of the UE based on releasing the RRC connection to the RRC inactive state.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging early indication that indicates one or more paging occasions (POs) in a quantity of paging frames based at least in part on a maximum quantity of paging frames. The UE may process a physical downlink control channel communication received in a PO of the one or more POs. Numerous other aspects are described.

According to the present specification, a fallback operation for when a terminal has not detected a DCI is newly proposed.

A paging method includes sending, by a terminal device, first indication information to a first network device in a first network, where the first indication information indicates that a first paging occasion (PO) needs to be updated, and receiving, by the terminal device, second indication information from the first network device, where the second indication information is used by the terminal device to determine a second PO.

Paging methods and apparatuses applicable to a communication system are disclosed. One method includes: A network device sends first paging configuration information, where the first paging configuration information corresponds a first-type terminal device; and sends second paging configuration information, where the second paging configuration information corresponds to a second-type terminal device. A capability of the first-type terminal device is different from a capability of the second-type terminal device. The second-type terminal device receives the second paging configuration information; and receives paging downlink control information (DCI) based on the second paging configuration information.

Embodiments of this application provide example communication methods and apparatuses. One example method includes receiving a paging message from a network device, where the paging message includes first information, and the first information is used to indicate a resource location of a public warning system message. The public warning system message is received based on the paging message.
