Description

Paging method and device
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a paging method and equipment.
Background
In a Long Term Evolution (LTE), New Radio (NR) Release 15(Release 15, R15) or Release 16(Release 16, R16) system, a terminal (e.g., a User Equipment (UE)) may monitor whether a Paging Radio Network temporary identifier (P-RNTI) is carried on a Physical Downlink Control Channel (PDCCH) only at a Paging time (Paging access, PO) on a corresponding Paging Radio Frame (PF) in a Discontinuous Reception (DRX) cycle, and further determine whether a Paging message is carried on a corresponding Physical Downlink Shared Channel (PDSCH).
If the UE resolves the P-RNTI carried on the PDCCH, receiving data on the PDSCH according to the PDSCH parameters indicated on the PDCCH; if the paging message (data on PDSCH) received by the UE has a UE Identity (ID) list, the terminal needs to match the UE ID with the UE ID list carried in the paging message to determine whether the paging message is calling itself.
If the UE does not resolve the P-RNTI on the PDCCH, the UE can enter the sleep mode according to the DRX period without receiving data on the PDSCH.
If any UE in a group of UEs with the same PO needs to be paged and the UE ID of the UE is included in a Paging PDSCH corresponding to the PO, the group of UEs may resolve a P-RNTI on the PDCCH and then receive data on the Paging PDSCH. However, only the paged UE finds its own UE ID in the UE ID list in the paging message (data on PDSCH), and no other UE finds its own UE ID in the UE ID list in the paging message after receiving the paging message. This phenomenon is called unnecessary paging PDSCH reception, and for UEs that do not need to be paged, receiving unnecessary paging PDSCH consumes power of the UE.

Embodiments of the present invention are described below with reference to the drawings. The paging method and the paging device provided by the embodiment of the invention can be applied to a wireless communication system. Referring to fig. 1, an architecture diagram of a wireless communication system according to an embodiment of the present invention is shown. As shown in fig. 1, the wireless communication system may include: network device 11 and terminal 12, terminal 12 may be referred to as UE12, and terminal 12 may communicate (transmit signaling or transmit data) with network device 11. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation.
The network device 11 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network device in a 5G system (e.g., a next generation base station (gNB) or a Transmission and Reception Point (TRP)).
The terminal 12 provided in the embodiment of the present invention may be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device.
Referring to fig. 2, an embodiment of the present invention provides a paging method, where an execution subject of the method is a terminal (e.g., a terminal of an above-R17 or R17 version), and the method includes: step 201 and step 202.
Step 201: detecting first paging Downlink Control Information (DCI), wherein a reserved bit (reserve bit) in the first paging DCI, a reserved bit in a short message, or a short message bit (short message bit) indicates one or more of the following: information of the paged terminal; whether to detect a second paging DCI;
step 202: and determining whether the terminal is paged according to the detection result of the first paging DCI and/or the detection result of the second paging DCI.
The first DCI is DCI which needs to be detected by a terminal adopting a first communication protocol or a second communication protocol, the second paging DCI is DCI which needs to be detected by a terminal adopting a second communication protocol, and the version number of the first communication protocol is lower than that of the second communication protocol.
For example, the first communication protocol is a communication protocol of a version R15 or R16, and the second communication protocol is a communication protocol of a version R17 or more than R17. It can be understood that the behavior of the terminal of the above version of R17 or R17 to receive the bits related to the short message in the paging DCI is the same as the behavior of the terminal of R15 or R16 to receive the bits related to the short message in the paging DCI.
It can be understood that the paging DCI may also be referred to as a paging PDCCH-carried DCI, and the paging DCI may include: (1) short message Indicator (Short Messages Indicator); (2) short message bits (Short Messages bits); (3) frequency domain resource allocation (Frequency domain resource allocation); (4) time domain resource allocation (Time domain resource assignment); (5) mapping (VRB-to-PRB mapping) virtual resource blocks to physical resource blocks; (6) modulation and coding scheme (Modulation and coding scheme); (7) transport block extension (TB scaling); (8) reserved bits (Reserved bits).
The content in the short message indicator may include the following code points (code points), and different values of the code points have different meanings, for example:
(1)00, indicating Reserved (Reserved);
(2)01, indicating that only scheduling information for scheduling exists in the DCI;
(3)10, indicating that only short messages exist in the DCI;
(4) and 11, indicating that the scheduling information and the short message for paging exist in the DCI at the same time.
In this embodiment of the present invention, the first paging DCI may be an existing paging DCI (or referred to as a legacy paging DCI), and indicate information of the paged terminal through a reserved bit of the existing paging DCI, or the first paging DCI may also be a new paging DCI, and indicate information of the paged terminal through the new paging DCI. It is to be understood that the specific form of the first paging DCI is not limited.
In the embodiment of the present invention, one or more of the following items may be determined by system information, or protocol convention, or a code point in a Short Message indicator (Short Message indicator) in the first paging DCI:
(1) whether all or part of bits in reserved bits in the first paging DCI, reserved bits in the short message or bits in the short message are used for indicating information of a paged terminal and/or whether second paging DCI is detected;
(2) whether all or part of bits in reserved bits in the first paging DCI, reserved bits in the short message or bits in the short message are used for indicating information of a paged terminal and/or whether second paging DCI is detected;
(3) whether all or part of bits of reserved bits of the short message, or bits of the short message in the first paging DCI are used for indicating information of a paged terminal and/or whether a second paging DCI is detected;
(4) and the reserved bit of the short message in the first paging DCI, the reserved bit in the short message, or the bit in the short message bit for indicating the paged terminal and/or detecting whether to detect the second paging DCI.
In this embodiment of the present invention, if a Short message Indicator (Short Messages Indicator) in the first paging DCI is a first value, for example, 10, all or a part of bits of a Short message in the first paging DCI indicate information of a paged terminal.
In some embodiments of the present invention, a terminal using a first communication protocol and a terminal using a second communication protocol may share one Paging DCI (Paging DCI), and after detecting the Paging DCI, the terminal using the second communication protocol may determine whether to be paged according to an indication of a reserve bit in the Paging DCI and/or a reserve bit in a short message bit, without detecting a PDSCH corresponding to the Paging DCI, so that unnecessary receiving of the Paging PDSCH is reduced compared with the prior art, and power saving of the terminal is facilitated.
In other embodiments of the present invention, if the detected first paging DCI indicates to detect the second paging DCI, the second paging DCI is detected, and it is determined whether the terminal is paged according to a detection result of the first paging DCI and/or a detection result of the second paging DCI; wherein bits in the second paging DCI indicate information of a paged terminal. For example, a part of the information of the paged terminal is carried in the reserve bit in the Paging DCI and/or the reserve bit in the short message bit, and the other part is carried in the second Paging DCI. For another example, if the number of paged terminals belonging to the same PO is small, the information of the paged terminals is all carried in the reserve bit in the Paging DCI and/or the reserve bit in the short message bit; if the number of the paged terminals belonging to the same PO is large, the information of the paged terminals can also be carried in the second paging DCI.
For example, if the reserved bits of the first paging DCI or the reserved bits of the short message or the short message bits of the short message indicate that the terminal needs to detect the second DCI, or the code point of the short message indication bits of the first paging DCI is not a second value, for example, 10, then the second paging DCI is detected.
In this embodiment, a terminal (for example, a terminal of an version above R17 or R17) using the second communication protocol may first detect the first Paging DCI (equivalent to the conventional Paging DCI), and then determine whether to detect the second Paging DCI (equivalent to the new Paging DCI) according to the indication of the first Paging DCI.
In this embodiment of the present invention, the information of the paged terminal includes: the terminal identification (UE ID) of the paged terminal, or part of the information of the terminal identification of the paged terminal, or information related to the terminal identification of the paged terminal.
Further, the UE ID is related to a paging occasion of a terminal employing the second communication protocol (e.g., a terminal of a release above R17 or R17).
For example, the UE ID is compressed by a hash function to N bits for transmission, N being a positive integer; the UE ID may be one of an International Mobile Subscriber Identity (IMSI), an International Mobile Equipment Identity (IMEI), a Temporary Mobile Station Identity (TMSI), a 5G-S-TMSI, or other types of UE IDs.
Further, the terminal matches the UE ID with the N bit in the first paging DCI to determine whether the first paging DCI is paging the UE. For example, if the information of the paged terminal detected by the terminal includes the terminal identification information of the terminal or partial information including the terminal identification of the terminal, it is determined that the terminal is paged.
In this embodiment of the present invention, optionally, the second paging DCI has a corresponding paging PDSCH.
In this embodiment of the present invention, optionally, the second paging DCI does not have a corresponding paging PDSCH.
In this embodiment of the present invention, optionally, the size of the second paging DCI is a protocol agreement or a network side configuration.
In the embodiment of the present invention, optionally, the P-RNTI of the second paging DCI is a protocol agreement or a network side configuration.
In this embodiment of the present invention, the second paging DCI and the first paging DCI are configured with any one of the following:
(1) the same common search space, and different P-RNTIs;
(2) different common search spaces, and the same P-RNTI;
(3) different common search spaces, and different P-RNTIs;
(4) the same or different PF;
(5) the same or different PO;
(6) the same or different paging control resource sets (paging coreset).
Optionally, the second paging DCI and the first paging DCI are configured with a same listening occasion (monitoring occasion). Alternatively, when the reserved code point of the short message indicator (short message indicator) is "00", it represents that the related paging DCI is the second paging DCI. This has the advantage that there is no need to introduce a new P-RNTI to distinguish the second paging DCI from the first paging DCI.
In the embodiment of the invention, the terminal can determine whether the Paging DCI is the paged terminal according to the received Paging DCI containing the information of the paged terminal without receiving the Paging PDSCH, thereby effectively saving the electric quantity of the terminal.
Referring to fig. 3, an embodiment of the present invention further provides a paging method, where the main execution subject of the method is a terminal (for example, a terminal of an above-mentioned version of R17 or R17), and the method includes: step 301 and step 302.
Step 301: detecting third paging DCI, wherein the third paging DCI indicates information of a paged terminal;
step 302: determining whether the terminal is paged according to the third paging DCI;
and the third paging DCI is DCI which needs to be detected by the terminal adopting the second communication protocol.
In some embodiments, the method may further comprise: detecting fourth paging DCI, wherein the fourth paging DCI is DCI which needs to be detected by a terminal adopting a first communication protocol or a second communication protocol; wherein a version number of the first communication protocol is lower than a version number of the second communication protocol.
For example, the first communication protocol is a communication protocol of a version R15 or R16, and the second communication protocol is a communication protocol of a version R17 or more than R17. It can be understood that the behavior of the terminal of the above version of R17 or R17 to receive the bits related to the short message in the paging DCI is the same as the behavior of the terminal of R15 or R16 to receive the bits related to the short message in the paging DCI.
Optionally, bits of the short message in the fourth paging DCI indicate information of the paged terminal.
In the embodiment of the present invention, a terminal (for example, a UE above R17 or R17) using a second communication protocol needs to detect a third Paging DCI and a fourth Paging DCI, where the third Paging DCI is equivalent to a new Paging DCI, and the fourth Paging DCI is equivalent to a conventional Paging DCI. Therefore, the terminal detects the two Paging DCIs and judges whether the Paging is carried out according to the indication in the new Paging DCI, compared with the prior art, unnecessary Paging PDSCH receiving is reduced, and the power saving of the terminal is facilitated.
In some embodiments, a terminal adopting the second communication protocol (e.g., a terminal of a version above R17 or R17) may detect only the third paging DCI, and further, the third paging DCI further includes: a related indication of a short message, and/or a related indication of resource scheduling.
In some embodiments, a terminal employing the second communication protocol receives bits of the short message in the third paging DCI.
In this embodiment, the terminal adopting the second communication protocol may only detect the third Paging DCI (equivalent to the new Paging DCI), and after detecting the third Paging DCI, may determine whether to be paged according to an indication of the third Paging DCI, so as to reduce unnecessary Paging PDSCH reception compared to the prior art, thereby facilitating power saving of the terminal.
In this embodiment of the present invention, optionally, the third paging DCI has a corresponding paging PDSCH.
In this embodiment of the present invention, optionally, the third paging DCI does not have a corresponding paging PDSCH.
In this embodiment of the present invention, optionally, the size of the third paging DCI is a protocol agreement or a network side configuration.
In this embodiment of the present invention, optionally, a paging radio network temporary identifier (P-RNTI) of the third paging DCI is a protocol agreement or a network side configuration.
In this embodiment of the present invention, the third paging DCI and the fourth paging DCI are configured with any one of the following items:
(1) the same common search space, and different P-RNTIs;
(2) different common search spaces, and the same P-RNTI;
(3) different common search spaces, and different P-RNTIs;
(4) the same or different PF;
(5) the same or different PO;
(6) the same or different paging control resource sets (paging coreset).
Optionally, the third paging DCI and the fourth paging DCI are configured with the same listening time monitoring occasion.
Alternatively, when the reserved code point of the short message indicator (short message indicator) is "00", it represents that the related paging DCI is the third paging DCI. This has the advantage that there is no need to introduce a new P-RNTI to distinguish between the third paging DCI and the fourth paging DCI.
In this embodiment of the present invention, the information of the paged terminal includes: the terminal identification (UE ID) of the paged terminal, or partial information of the terminal identification of the paged terminal.
Further, the UE ID is related to a paging occasion of a terminal employing the second communication protocol (e.g., a terminal of a release above R17 or R17).
For example, the UE ID is compressed by a hash function to N bits for transmission, N being a positive integer; wherein, the UE ID can be one of IMSI, IMEI, TMSI, 5G-S-TMSI, etc., or other types of UE ID.
Further, the terminal matches the UE ID with the N bit in the third paging DCI to determine whether the first paging DCI is paging the UE. For example, if the information of the paged terminal detected by the terminal includes terminal identification information of the terminal or partial information including the terminal identification of the terminal, it is determined that the terminal is paged.
In the embodiment of the invention, the terminal can determine whether the Paging DCI is the paged terminal according to the received Paging DCI containing the information of the paged terminal without receiving the Paging PDSCH, thereby effectively saving the electric quantity of the terminal.
Referring to fig. 4, an embodiment of the present invention further provides a paging method, where an execution subject of the method is a network device, and the method includes: step 401.
Step 401: sending a first paging DCI to a terminal, wherein a reserved bit in the first paging DCI, a reserved bit in a short message or a short message bit indicates one or more of the following items: information of the paged terminal; whether to detect a second paging DCI;
the first paging DCI is DCI which needs to be detected by a terminal adopting a first communication protocol or a second communication protocol, the second paging DCI is DCI which needs to be detected by the terminal adopting the second communication protocol, and the version number of the first communication protocol is lower than that of the second communication protocol.
It is understood that the embodiment of the network side shown in fig. 4 corresponds to the embodiment of the terminal side shown in fig. 2, and the description of the similar contents can refer to the description of the embodiment shown in fig. 2.
In the embodiment of the invention, the Paging DCI sent by the network equipment comprises the information of the paged terminal, so that the terminal can determine whether the terminal is the paged terminal according to the information after detecting the Paging DCI without receiving the Paging PDSCH, thereby effectively saving the electric quantity of the terminal.

It is understood that the embodiment of the network side shown in fig. 5 corresponds to the embodiment of the terminal side shown in fig. 5, and the description of the similar contents can refer to the description of the embodiment shown in fig. 5.
In the embodiment of the invention, the Paging DCI sent by the network equipment comprises the information of the paged terminal, so that the terminal can determine whether the terminal is the paged terminal according to the information after detecting the Paging DCI without receiving the Paging PDSCH, thereby effectively saving the electric quantity of the terminal.
The paging method in the embodiment of the present invention is described below with reference to the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment.
The first embodiment is as follows: new and old releases of UE share one paging DCI
Detecting first paging Downlink Control Information (DCI), wherein a reserved bit (reserve bit) in the first paging DCI, a reserved bit in a short message, or a short message bit (short message bit) indicates one or more of the following: information of the paged terminal; and determining whether the terminal is paged or not according to the detection result of the first paging DCI.
In this embodiment, the R15/R16 UE (old UE), and R17 or later releases UE (new UE) detect the same paging DCI. For R17 or later versions of the UE, the paging DCI is detected and an indication is received of the reserved bit and/or the short message bit therein.
For example, the PO-related UE ID information or UE ID partial information of R17 or a later version UE (new UE) is transmitted by using the reserve bit (6bits) in the paging DCI and/or the reserve bit (6bits) in the short message bit, for example, the UE ID is compressed into N bits by a hash function for transmission; wherein, the UE ID is one of IMSI, IMEI, TMSI, 5G-S-TMSI, etc., or other types of UE ID;
a) the new UE needs to match the N bit carried by the paging DCI with its UE ID to determine whether the paging message is calling itself.
The new UE receives short message related bit in the paging DCI (the action is the same as that of the old UE);
optionally, the system information informs about the usage of the reserve bit/short message bit, such as for informing about R17 or a later version of the UE, whether all or part of the reserve bit/short message bit is used to indicate UE ID information or UE ID part information, or,
optionally, the reserved Bit/Short Message Bit usage is notified by the reserved Bit field (00) of the Short Message indicator, such as for notifying R17 or a later-version UE, whether all or part of the reserved bits of the reserved Bit/Short Message Bit are used to indicate UE ID information or UE ID part information.
In the first embodiment, after detecting the Paging DCI, the new UE can determine whether to be paged according to the indication of the reserve bit in the DCI and/or the reserve bit in the short message bit, without detecting the PDSCH corresponding to the Paging DCI.
Example two: the new UE detects two paging DCIs.
Detecting third paging DCI and fourth paging DCI, wherein the third paging DCI indicates the information of a paged terminal; determining whether the terminal is paged according to the third paging DCI and the fourth paging DCI together; the third paging DCI is DCI which needs to be detected by a terminal adopting a second communication protocol, and the fourth paging DCI is DCI which needs to be detected by a terminal adopting the first communication protocol or the second communication protocol; wherein a version number of the first communication protocol is lower than a version number of the second communication protocol.
In this embodiment, R17 or later-release UE (new UE) detects two paging DCIs, where one legacy DCI (i.e. DCI that R15/R16 UE needs to detect) and one new DCI are used to inform R17 or later-release UE whether to wake itself up.
In this embodiment, PO-related UE ID information or UE ID partial information of R17 or UE of later release is transmitted using new DCI, for example, UE ID is compressed into N bits by hash function for transmission; wherein, the UE ID is one of IMSI, IMEI, TMSI, 5G-S-TMSI, etc., or other types of UE ID
a) The UE needs to match the N bit carried by the paging DCI with its own UE ID to determine whether the paging message is calling itself.
In this embodiment, the new UE receives bits related to the short message in the legacy paging DCI;
in this embodiment, the New paging DCI may or may not have a corresponding paging PDSCH
In this embodiment, the new paging DCI size, P-RNTI is protocol defined or base station configured, and is the same/different from the R16 paging DCI size.
In this embodiment, the new paging PDCCH and the old paging PDCCH may be configured with:
the same Type2-PDCCH CSS, but different P-RNTI(s), or
Different Type2-PDCCH CSS(s) and the same P-RNTI, or
Different Type2-PDCCH CSS(s) and different P-RNTI(s), or
The same or different PF (s)/PO(s), or
The same or different paging coresets.
Alternatively, the different CSSs may be different types of CSSs.
In this embodiment, the new UE detects two Paging DCIs, and determines whether to be paged according to an indication in the new DCI, which reduces unnecessary Paging PDSCH reception compared with the prior art, and is beneficial to UE power saving.
Example three: the new UE detects legacy DCI, and then determines whether to detect a second paging DCI (new DCI) according to the indication of legacy DCI.
Detecting first paging Downlink Control Information (DCI), wherein a reserved bit (reserve bit) in the first paging DCI, a reserved bit in a short message, or a short message bit (short message bit) indicates whether to detect the second paging DCI.

In this embodiment, the new UE determines whether to detect the second paging DCI according to the reserved Bit (6bits) in the legacy DCI and/or the reserved Bit field, "10", of the reserved Bit (6bits) in the Short Message Bit, or the Short Message indicator Bit.
a) If Bit in the reserved Bit (6bits) in the legacy DCI and/or the reserved Bit (6bits) in the Short Message Bit indicates that the UE needs to detect the new DCI, or the reserved Bit field of the Short Message indicator Bit is not '10' (not only Short Message), the UE detects the new DCI;
b) otherwise, the UE does not detect the new DCI.
In this embodiment, the second paging DCI is a new paging DCI, and includes PO-related UE ID information or UE ID partial information of R17 or a later-version UE, and the UE ID is compressed into N bits by a hash function for transmission; wherein, the UE ID is one of IMSI, IMEI, TMSI, 5G-S-TMSI, etc., or other types of UE ID.
a) The UE needs to match the N bit carried by the paging DCI with its UE ID to determine whether the paging message is calling itself.
In this embodiment, the new UE receives bits related to the short message in the legacy paging DCI;
a) if the new UE detects that the Short Message indicator bit is '10', the UE does not need to detect the new DCI;
b) otherwise, the UE needs to detect the new DCI.
