Abstract

Embodiments of the present application are directed to a method and apparatus for paging dedicated for devices with reduced capabilities. The method may include: receiving a DCI identified with a P-RNTI in a PO; and obtaining information dedicated for a device with reduced capabilities according to the DCI.

First claim

What is claimed is:

1 . A user equipment (UE) for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the UE to:
receive a downlink control information (DCI) identified with a paging-radio network temporary identifier (P-RNTI) in a paging occasion (PO); and
obtain information for a device with reduced capabilities according to the DCI identified with the P-RNTI, the information configured to cause the UE to obtain an initial bandwidth part (IBWP) configuration update for the device with reduced capabilities.

2 . The UE of claim 1 , wherein the information for the device with reduced capabilities comprises at least one of:
a short message indicator for the device with reduced capabilities; a short message for the device with reduced capabilities; scheduling information for a paging message for the device with reduced capabilities; or a paging message for the device with reduced capabilities.

3 . The UE of claim 2 , wherein the short message indicator for the device with reduced capabilities comprises indication information of one or more of:
scheduling information for paging for the device with reduced capabilities is present in the DCI; short message for the device with reduced capabilities is present in the DCI; or both scheduling information for paging and short message for the device with reduced capabilities are present in the DCI, and wherein the short message indicator for the device with reduced capabilities is indicated using reserved bits in the short message indicator for legacy devices.

4 . The UE of claim 2 , wherein the short message for the device with reduced capabilities is indicated using reserved bits in the short message for legacy devices, and wherein the short message for the device with reduced capabilities comprises at least one of:
indication information on system information modification for the device with reduced capabilities; or indication information on stop paging monitoring for the device with reduced capabilities.

5 . The UE of claim 4 , wherein the PO is for the device with reduced capabilities and the system information modification for the device with reduced capabilities comprises: activation or deactivation of configurations for the device with reduced capabilities.

6 . The UE of claim 4 , wherein the system information modification for the device with reduced capabilities comprises the IBWP configuration update for the device with reduced capabilities, and wherein the at least one processor is operable to cause the UE to receive the paging message to obtain the IBWP configuration update for the device with reduced capabilities according to the scheduling information for the paging message.

7 . The UE of claim 2 , wherein:
the DCI is a scheduling DCI for the short message and the paging message for the device with reduced capabilities, which is addressed by P-RNTI that is for the device with reduced capabilities; the P-RNTI is one or more of predefined or configured in system information block 1 (SIB1); and the at least one processor is operable to cause the UE to receive SIB1 to obtain system information modification for the device with reduced capabilities.

8 . The UE of claim 7 , wherein the at least one processor is operable to cause the UE to:
receive the paging message for the device with reduced capabilities according to the scheduling information in the scheduling DCI with the P-RNTI for the device with reduced capabilities, wherein the paging message for the device with reduced capabilities comprises system information modification for the device with reduced capabilities.

9 . The UE of claim 8 , wherein the system information modification comprises: information on enabling, disabling, or updating of IBWP for the device with reduced capabilities in system information block.

10 . The UE of claim 8 , wherein the system information modification comprises: information on enabling, disabling, or updating of synchronization signal block (SSB) configurations for the device with reduced capabilities.

11 . The UE of claim 1 , wherein the at least one processor is operable to cause the UE to perform one or more of to:
receive an update of a common part of IBWP configuration in a device specific signaling; receive an update of SSB configuration in a device specific signaling; select one IBWP from a plurality of IBWPs based on at least one of a device type and a device ID; or receive the common part of IBWP in a device specific signaling.

12 . The UE of claim 1 , wherein the at least one processor is operable to cause the UE to:
receive a configuration indicating an IBWP for the device with reduced capabilities; and switch to the IBWP for the device with reduced capabilities.

13 . The UE of claim 12 , wherein to switch to the IBWP for the device with reduced capabilities, the at least one processor is operable to cause the UE to:
switch to the IBWP for the device with reduced capabilities when a timer expires.

14 . The UE of claim 12 , wherein the at least one processor is operable to cause the UE to:
start a timer when the device with reduced capabilities is on the IBWP for the device with reduced capabilities; and switch to a second IBWP when the timer expires.

15 . A network entity for wireless communication, comprising:
at least one memory; and at least one processor coupled with the at least one memory and operable to cause the network entity to:
transmit a downlink control information (DCI) identified with a paging-radio network temporary identifier (P-RNTI) in a paging occasion (PO), wherein the DCI comprises information for a device with reduced capabilities, the information comprising initial bandwidth part (IBWP) configuration update for the device with reduced capabilities.

16 . The network entity of claim 15 , wherein the information for the device with reduced capabilities comprises at least one of:
a short message indicator for the device with reduced capabilities; a short message for the device with reduced capabilities; scheduling information for a paging message for the device with reduced capabilities; or a paging message for the device with reduced capabilities.

17 . The network entity of claim 16 , wherein the short message indicator for the device with reduced capabilities comprises indication information of one or more of:
scheduling information for paging for the device with reduced capabilities is present in the DCI; short message for the device with reduced capabilities is present in the DCI; or both scheduling information for paging and short message for the device with reduced capabilities are present in the DCI.

18 . The network entity of claim 16 , wherein the short message for the device with reduced capabilities comprises at least one of:
indication information on system information modification for the device with reduced capabilities; or indication information on stop paging monitoring for the device with reduced capabilities.

19 . The network entity of claim 16 , wherein:
the DCI is a scheduling DCI for the paging message for the device with reduced capabilities, which is addressed by P-RNTI that is for the device with reduced capabilities; the at least one processor is operable to cause the network entity to transmit the paging message for the device with reduced capabilities according to the scheduling information in the scheduling DCI with the P-RNTI for the device with reduc
