Paging indicating method, terminal device and network device
View Patent ↗The embodiments of the present disclosure provide a paging indicating method, a terminal device, and a network device, capable of avoiding monitoring a paging message at a paging occasion when a terminal device does not need to receive the paging message, thereby achieving power saving of the terminal. The paging indicating method includes: receiving, by a terminal device, indication information corresponding to at least one terminal group and indicating whether terminals in the corresponding terminal group monitor a paging message.
1 . A paging indicating method, comprising:
receiving, by a terminal device, indication information corresponding to at least one terminal group and indicating whether terminals in the corresponding terminal group are to monitor for a paging message;
wherein the indication information is carried in Downlink Control Information (DCI), and the number of available bits in the indication information is equal to a number of reserved bits in the DCI, or the number of available bits in the indication information is equal to a number of bits that are a part of the reserved bits in the DCI, or the number of available bits in the indication information is equal to a number of reserved bits in the DCI other than a first bit, or the number of available bits in the indication information is equal to a number of bits that are a part of the reserved bits in the DCI other than the first bit;
wherein the first bit indicates an available reference signal.
2 . The method according to claim 1 , wherein a number of terminal groups corresponding to the indication information is pre-configured, or agreed in a protocol, or the number of terminal groups corresponding to the indication information is configured or indicated by a network device via higher layer signaling.
3 . The method according to claim 1 , wherein the terminal group is:
determined based on identifiers of terminals; or
determined based on access classes of terminals.
4 . The method according to claim 1 , wherein the indication information is Paging Early Indication (PEI) information.
5 . The method according to claim 1 , wherein the terminal device is in an idle state or an inactive state.
6 . The method according to claim 1 , wherein the indication information is carried in a Physical Downlink Control Channel (PDCCH), and the PDCCH is a specially configured PDCCH dedicated to carrying the indication information.
7 . The method according to claim 6 , wherein
the indication information occupies N groups of bits, and each of the N groups of bits includes M bits, where N and M are positive integers, each of the N groups of bits corresponding to one paging occasion, and each of the M bits corresponding to one terminal group.
8 . The method according to claim 7 , wherein a bit value of each bit occupied by the indication information indicates whether the terminals in the corresponding terminal group monitor the paging message at the corresponding paging occasion.
9 . The method according to claim 1 , wherein the available reference signal is used for time-frequency synchronization and/or Radio Resource Management (RRM) measurement of the terminal device when receiving the paging message.
10 . The method according to claim 1 , wherein the available reference signal comprises an available reference signal out of a plurality of reference signals, and configuration information for the plurality of reference signals is configured by a network device via system information or Radio Resource Control (RRC) signaling.
11 . The method according to any one of claims 1 , wherein a number of bits included in the first bit is pre-configured, or agreed in a protocol, or the number of bits included in the first bit is configured by a network device, or the number of bits included in the first bit is determined based on configuration information for a plurality of reference signals and the available reference signal comprises an available reference signal out of the plurality of reference signals.
12 . The method according to claim 1 , wherein
an order of bits corresponding to respective terminal groups is determined according to identifiers of the terminal groups; or
an order of bits corresponding to respective terminal groups is determined according to time domain positions of paging occasions corresponding to the indication information.
13 . A paging indicating method, comprising:
transmitting, by a network device, indication information corresponding to at least one terminal group and indicating whether terminals in the corresponding terminal group are to monitor for a paging message;
wherein the indication information is carried in Downlink Control Information (DCI), and the number of available bits in the indication information is equal to a number of reserved bits in the DCI, or the number of available bits in the indication information is equal to a number of bits that are a part of the reserved bits in the DCI, or the number of available bits in the indication information is equal to a number of reserved bits in the DCI other than a first bit, or the number of available bits in the indication information is equal to a number of bits that are a part of the reserved bits in the DCI other than the first bit;
wherein the first bit indicates an available reference signal.
14 . A network device, comprising a processor and a memory, wherein the memory has a computer program stored thereon, and the processor is configured to invoke and execute the computer program stored in the memory to perform the method according to claim 13 .
15 . The method according to claim 13 , wherein the available reference signal is used for time-frequency synchronization and/or Radio Resource Management (RRM) measurement of the terminal device when receiving the paging message.
16 . A terminal device, comprising a processor and a memory, wherein the memory has a computer program stored thereon, and the processor is configured to invoke and execute the computer program stored in the memory to:
receive indication information corresponding to at least one terminal group and indicating whether terminals in the corresponding terminal group are to monitor for a paging message;
wherein the indication information is carried in Downlink Control Information (DCI), and the number of available bits in the indication information is equal to a number of reserved bits in the DCI, or the number of available bits in the indication information is equal to a number of bits that are a part of the reserved bits in the DCI, or the number of available bits in the indication information is equal to a number of reserved bits in the DCI other than a first bit, or the number of available bits in the indication information is equal to a number of bits that are a part of the reserved bits in the DCI other than the first bit;
wherein the first bit indicates an available reference signal.
17 . The terminal device according to claim 16 , wherein a number of terminal groups corresponding to the indication information is pre-configured, or agreed in a protocol, or the number of terminal groups corresponding to the indication information is configured or indicated by a network device via higher layer signaling.
18 . The terminal device according to claim 16 , wherein the terminal group is:
determined based on identifiers of terminals; or
determined based on access classes of terminals.
19 . The terminal device according to claim 16 , wherein the indication information is Paging Early Indication (PEI) information.
20 . The terminal device according to claim 16 , wherein the terminal device is in an idle state or an inactive state.
