Abstract
Methods and device for paging configuration and power saving in wireless terminal devices are disclosed. The disclosed method may be performed by a wireless terminal device. The method may include receiving paging subgroup configuration information from a wireless network; determining a paging subgroup identifier based on the paging subgroup configuration information and a paging subgroup mode of the wireless terminal device; and determining whether to wake up to monitor a paging occasion based on whether the paging subgroup identifier is indicated prior to an arrival of the paging occasion.
Claims20
A method performed by a wireless terminal device, comprising:
- receiving paging subgroup configuration information from a wireless network;
- determining a paging subgroup identifier based on the paging subgroup configuration information;
- and
- determining whether to wake up to monitor a paging occasion based on whether the paging subgroup identifier corresponding to the paging occasion is indicated in a Downlink Control Information (DCI) message prior to an arrival of the paging occasion,
- wherein the paging subgroup identifier indicates either a paging subgroup among a first type of paging subgroups or another paging subgroup among a second type of paging subgroups;
- wherein first paging subgroup identifiers corresponding to the first type of paging subgroups are assigned by a core network and second paging subgroup identifiers corresponding to the second type of paging subgroups are generated based on a UE identifier (UE ID);
- and
- wherein the first paging subgroup identifiers and the second paging subgroup identifiers are sequentially numbered with the second paging subgroup identifiers being greater than the first paging subgroup identifiers.
A method performed by a wireless terminal device, comprising:
- receiving paging subgroup configuration information from a wireless network;
- determining a paging subgroup identifier based on the paging subgroup configuration information;
- and
- determining whether to wake up to monitor a paging occasion based on whether the paging subgroup identifier corresponding to the paging occasion is indicated in a Downlink Control Information (DCI) message prior to an arrival of the paging occasion, wherein the paging subgroup identifier indicates either a paging subgroup among a first type of paging subgroups or another paging subgroup among a second type of paging subgroups;
- wherein first paging subgroup identifiers corresponding to the first type of paging subgroups are assigned by a core network and second paging subgroup identifiers corresponding to the second type of paging subgroups are generated based on a UE identifier (UE ID) according to mod (floor (UE_ID/(N*Ns)), Nsg)+NCN, wherein:
- UE_ID is the UE identifier;
- N is a number of total paging frames in a DRX paging cycle;
- Ns is a predefined number of paging occasions (POs) in a paging frame;
- Nsg is a number of the second type of paging subgroups;
- and
- NCN is a number of the first type of paging subgroups.
A wireless terminal device, comprising a memory for storing instructions and at least one processor configured to execute the instructions to:
- receive paging subgroup configuration information from a wireless network;
- determine a paging subgroup identifier based on the paging subgroup configuration information;
- and
- determine whether to wake up to monitor a paging occasion based on whether the paging subgroup identifier corresponding to the paging occasion is indicated in a Downlink Control Information (DCI) message prior to an arrival of the paging occasion,
- wherein the paging subgroup identifier indicates either a paging subgroup among a first type of paging subgroups or another paging subgroup among a second type of paging subgroups;
- wherein first paging subgroup identifiers corresponding to the first type of paging subgroups are assigned by a core network and second paging subgroup identifiers corresponding to the second type of paging subgroups are generated based on a UE identifier (UE ID);
- and
- wherein the first paging subgroup identifiers and the second paging subgroup identifiers are sequentially numbered with the second paging subgroup identifiers being greater than the first paging subgroup identifiers.
