Description

Method for receiving and sending paging message, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for receiving and sending a paging message, a terminal device, and a network device.

Background

A Radio access (New Radio, NR) system supports multi-beam operation. Each beam has its own directivity and can only cover terminals in a certain direction, so that the transmitting end needs to transmit beams in more directions to realize omni-directional coverage. In the NR system, since a higher carrier frequency band is used, the application of the beamforming technology limits the coverage area of a single transmit antenna port to a smaller angle, and at this time, the network side cannot know the beam ranges of the IDLE UE and the INACTIVE UE. Therefore, in order to ensure coverage of the potential location of the UE, the network side needs to repeatedly transmit the paging message in a full beam. And the UE determines a Paging radio Frame (PF) and a Paging Occasion (PO) for receiving the Paging message according to the UE ID, the Paging cycle, the number of times of Paging configured by the network, and other parameters.

In consideration of energy saving, the UE needs to monitor the energy saving signal before monitoring a Physical Downlink Control Channel (PDCCH), and if the UE knows that a PDCCH message is sent by monitoring the energy saving signal, the UE continues to monitor the PDCCH signal, otherwise, the UE does not monitor the corresponding PDCCH signal but monitors the energy saving signal at the next time, so as to achieve the purpose of energy saving.

In the prior art, the receiving position of the paging message by the UE is calculated according to the UE ID, and the energy saving signal is transmitted a fixed time length before the position (for example, PO) where the paging message is received by the UE. However, in the NR system, during the beam scanning process, the network side may flexibly configure the beam directions of different slot lengths according to the services to receive the paging message, and if, according to the prior art, the energy-saving signal is sent a fixed time length before the location where the paging message is received, i.e., the slot length is only a fixed time length, it may cause the UE to receive the slot length that the paging message cannot be flexibly configured according to the services, i.e., it is not flexible.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly and completely understood, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

The following describes background art for embodiments of the present invention.

Referring to fig. 1, a transmission system of a paging message according to an embodiment of the present invention is first described, and the system shown in fig. 1 includes a network device and two terminal devices, which may actually include a plurality of terminal devices. The network device may send a paging message, paging parameters, PDCCH, etc. to the terminal device over the communication link. The terminal equipment receives paging messages, paging parameters, PDCCH and the like from the network equipment. Of course, the network device may also transmit a Synchronization Signal Block (SSB) or the like to the terminal device via the communication link, which will be described later.

In the prior art, the receiving position of the paging message by the terminal device is calculated according to the identification UE ID of the terminal device, and the energy saving signal is sent a fixed time length before the position (for example, PO) of the paging message received by the terminal device. However, in the NR system, during the beam scanning process, the network side may flexibly configure beam directions with different slot lengths according to the service to receive the paging message, and if, according to the prior art, the energy-saving signal is sent a fixed time length before the position where the paging message is received, i.e. the slot length is only a fixed time length, it may cause the terminal device to receive the paging message inflexibly. For example, the energy-saving signal is transmitted through a beam scanning process, and the beam scanning process for receiving the paging message needs to be performed after the beam scanning for receiving the energy-saving signal is finished, so that the time length between the energy-saving signal and the paging message needs to be set as the time length related to the beam scanning.

In view of this, embodiments of the present invention provide a method and a device for receiving and sending a paging message, in an embodiment of the present invention, a terminal device starts receiving a paging message at a first interval after receiving a first signal, where the first signal instructs the terminal device to perform an energy saving operation, which may be regarded as an energy saving signal, that is, a paging location is determined according to a receiving time of the energy saving signal, so as to receive the paging message at the paging location. Therefore, even if the beam directions with different time slot lengths exist in the beam scanning process, the receiving time of the energy-saving signal is flexibly adjusted, and the paging position is flexibly adjusted, so that the flexibility of the terminal equipment for receiving the paging message is improved.

The technical scheme provided by the embodiment of the invention is described in the following with the accompanying drawings of the specification.

Referring to fig. 2, an embodiment of the present invention provides a method for sending a paging message, where the method may be executed by a network device provided in the embodiment of the present invention, and a flow of the sending method is described as follows.

S101, the network equipment sends a first signal to the terminal equipment, wherein the first signal indicates the terminal equipment to execute energy-saving operation;

s102, the network equipment determines a first interval to determine a paging position; wherein the first interval indicates a time interval or a frequency domain interval of the paging location and the first signal;

s103, the network equipment sends a paging message to the terminal equipment at the paging position.

The network device is a sender of the first signal and the paging message, and the terminal device is a receiver of the first signal and the paging message, so in the following description, the flow of the method for receiving the paging message by the terminal device is also involved.

With continued reference to fig. 2, an embodiment of the present invention provides a method for receiving a paging message, where the method may be executed by a terminal device provided in the embodiment of the present invention, and a flow of the receiving method is described as follows.

S201, the terminal device determines a first interval, wherein the first interval indicates a time interval or a frequency interval between a paging position and a first signal, and the first signal indicates the terminal device to execute energy-saving operation;

s202, the terminal equipment determines a paging position according to the first interval;

s203, the terminal equipment receives the paging message at the paging position.

For the network device, in step S101, the network device sends a first signal to the terminal device, where the first signal is used to instruct the terminal device to perform an energy saving operation, so that the terminal device performs the energy saving operation after receiving the first signal, that is, the terminal device starts to receive the paging message at the paging location after receiving the first signal, otherwise, if the terminal device does not receive the first signal, the terminal device does not monitor the paging message. For example, if the terminal device receives the first signal, it starts to monitor the PDCCHs of N time lengths, otherwise it does not monitor the PDCCHs, so as to achieve the purpose of saving energy. Wherein N is a positive integer greater than or equal to 1. It should be noted that the N time lengths here may be characterized by time slots or symbols. In this embodiment of the present invention, the first signal may include a Wake Up Signaling (WUS) signal or a signal status pilot signal of a cell, such as a Channel status information reference signal (CSI-RS) or an SSB signal.

In a possible embodiment, the network device may first send the SSB to the terminal device, and then determine a second interval, where the second interval may indicate a time interval between the SSB and the first signal, so that the network device sends the first signal to the terminal device at a second interval after sending the SSB to the terminal device. Thus, the terminal device receives the SSB from the network device and may receive the first signal after the second interval.

In one embodiment, the network device may transmit the SSB to the terminal device by beam scanning, and the terminal device may determine the second interval according to a scanning period of the received SSB to receive the first signal according to the second interval. If the network device can transmit the SSB to the terminal device by beam scanning, the terminal device may obtain a scanning period of the SSB, thereby calculating a second interval between the first signal and the transmission position of the SSB. For example, if the SSB is currently transmitted by the network device through beam scanning, and the length of the beam scanning is R slots, the second interval may be a slot with the same value as the beam scanning period, or may be R symbols.

In one embodiment, the second interval deltaT is associated with an identity UE ID of the terminal device, and the network device or the terminal device may determine the second interval according to the UE ID. The second interval is obtained, for example, after modulo the paging message period by the UE ID. For easy understanding, please refer to fig. 3, the terminal device receives the first signal after receiving the second interval time after the SSB, wherein the transmission time window in fig. 3 refers to the transmission time window of the first signal.

In this embodiment of the present invention, the network device may also send the SSB to the terminal device first, and then determine the third interval, where the third interval may indicate a frequency domain interval between the SSB and the first signal, so that when the network device sends the SSB to the terminal device, the network device sends the first signal to the terminal device at the frequency domain interval indicated by the third interval. Thus, the terminal device calculates the frequency domain transmission position of the first signal according to the third interval, so that the first signal is received according to the third interval when the SSB is received.

In a possible embodiment, the terminal device determines the third interval according to the UE ID and the number of Radio Resource Blocks (RBs). For example, the third interval may be obtained after UE ID modulo the number of RBs, where the number of RBs may be the number of RBs on the initial Bandwidth part (BWP). Referring to fig. 4, the terminal device receives the first signal within the transmission time window, and after the terminal device receives the SSB and determines the third interval, the frequency domain location where the first signal is received may be determined according to the third interval.

For the terminal device, after receiving the first signal, the terminal device may begin receiving paging messages. In the embodiment of the present invention, it is considered that in the beam scanning process, the network device may flexibly configure the beam directions of different slot lengths according to the service to transmit the paging message, and the current first signal is transmitted a fixed time length before the position where the paging message is received, which may cause the terminal device to receive the paging message and the slot length that the network device cannot flexibly configure based on the service. Therefore, in the embodiment of the present invention, in step S201, the terminal device may determine a first interval, where the first interval is used to indicate a time interval or a frequency domain interval between the paging location and the first signal, so that in step S202, the terminal device may determine the paging location according to the first interval, so that in step S203, the terminal device receives the paging message at the paging location. The paging location in the embodiments of the present invention may be a paging subframe and/or a paging slot.

In the embodiment of the present invention, the first interval may indicate a time interval between the paging location and the first signal, and may also indicate a frequency domain interval between the paging location and the first signal. The type of the interval indicated by the first interval is different, and the manner of determining the first interval is also different, and the manner of determining the first interval when the first interval indicates the time interval and the first interval indicates the frequency domain interval will be described below.

The first determination method: a time interval of the paging location and the first signal is indicated for the first interval.

In a possible embodiment, the terminal device may determine the first interval according to the number S of beams, for example, the first interval may be S slots, S symbols, or S PDCCH listening times, or R slots or symbols of a scanning period in which the network device sends an SSB.

Specifically, the number S of beams may be any one of the following:

the first method comprises the following steps: the number S of beams may be a preset number S of beams, for example, the number S of beams agreed in advance by the terminal device and the network device.

And the second method comprises the following steps: the number of beams S may be the number of beams S notified in a broadcast message sent by the network device to the terminal device. For example, the network device notifies the number of beams S to the terminal device through a radio resource control RRC connection release message, or the network device notifies the number of beams S to the terminal device through dedicated signaling in a scenario such as Carrier Aggregation (CA) or Dual Connectivity (DC).

And the third is that: the number S of beams may be the number S of beams actually transmitted by the serving cell, where the number S of beams may be the number of beams notified in a broadcast message transmitted by the network device to the terminal device, or may also be the number of beams actually detected by the terminal device.

In the first determination mode, the first interval may also relate to a PF or a PO, and if the first interval relates to a PF or a PO, the terminal device may further determine the first interval according to the PF or the PO.

In a possible implementation, the network device may notify the terminal device of the parameter of receiving the paging message, where the parameter of the paging message may include, for example, a period (T) of the paging message, an offset PF _ offset of a PF frame, a number (N) of PFs in the paging message period, and the like, and may further include a parameter such as configuration information of a search space received by a PDCCH received by a PO. Thus, the terminal equipment can calculate the PF/PO position according to the paging message parameters. For example, the terminal device may calculate the location of the PF according to equation (1):

(SFN+PF_offset)mod T＝(T div N)*(UE ID mod N) (1)

in formula (1), SFN represents a Radio frame, PF _ offset is an offset of a PF frame transmitted by a broadcast message, T is a paging message period (where T is the shortest one of the following 3 values, a paging message period configured by Radio Resource Control (RRC), or a paging message period configured by a Non Access Stratum (NAS), or a default Discontinuous Reception (DRX) period of system information broadcast, and if the paging message period of the UE is not configured by RRC or NAS, T is a DRX period of the system broadcast message), N is the total number of PFs within T, and the ID of the terminal device is 5G-S-TMSI 1024%.

Assuming that T is 32, i.e., 32 Radio Frames (RF), UE ID is 5, N is 8, and PF _ offset is 3, and the formula (1) is substituted, the following formula (2) is obtained:

(SFN+3)mod 32＝(32div 8)*(5mod 32)＝4*5＝20 (2)

SFN is thus obtained as 17, 49, 81, …, (20+32 × M-3), …, where M is a positive integer greater than or equal to 0.

For another example, the terminal device may calculate the position of the PO according to equation (3):

i_s＝floor(UE ID/N)mod Ns (3)

in equation (3), i _ s represents a start position of a PDCCH listening slot set of paging message Downlink Control Information (DCI). In general, the calculation process of PO is divided into two calculation methods. One of them is a default association mode (default association) mode, i.e. associated with the remaining system information (RMSI) transmission position, i.e. the PDCCH listening slot and the RMSI listening slot of the paging message are the same. In the default association mode, Ns is 1 or 2. If Ns is 1, there is only one PO in the PF. When Ns is 2, PO is in the first half frame if i _ s is 0, and PO is in the second half frame if i _0 is 1. The PDCCH listening slot of RMSI is indicated.

Another non-default association (non-default association) method is used, which is independent of RMSI association location and obtains PO location through parameter paging message SearchSpace in broadcast message. The UE considers the i _ S +1 th PO as S consecutive PDCCH listening slots, where S represents the number of SSBs actually transmitted. The starting position Of the PO is related to the first PDCCH interception starting position (first PDCCH-Monitoring interruption Of PO) Of the parameter. Assuming that the first signal is transmitted a first interval before the PF/PO, in a possible embodiment, the terminal device may determine the location of the PF or PO, and after determining the location of the PF or PO, may calculate the time interval between the first signal and the PF or PO, i.e. the first interval.

For the sake of understanding, please refer to fig. 5, assuming that PF is a radio frame with SFN m and PO is consecutive symbols starting from the kth symbol in slot n, it can be seen from fig. 5 that the time interval between the transmission time windows W and PO of the first signal is the first interval. In the embodiment of the present invention, if the transmission time window W is located inside one slot, for example, in the nth symbol in one slot, and the nth symbol is neither the start position nor the end position of the slot, the transmission time window may be extended forward or backward to the slot edge. In fig. 5, a Radio Frame indicates a Radio Frame, a Slot indicates a Slot, a PF indicates a paging Radio Frame, a Symbol indicates a Symbol, and a PO indicates a paging occasion.

The second determination method is as follows: a frequency domain spacing of the paging location from the first signal is indicated for the first interval.

In a possible embodiment, the terminal device determines the first interval according to the UE ID and the number of RBs. For example, the first interval may be a result of UE ID modulo the number of RBs, where the number of RBs may be the number of RBs on the initial Bandwidth part (BWP).

After the network device sends the first signal, the paging message is sent to the terminal device according to the first interval. And after the terminal device determines the first interval, the paging location may be determined according to the length of the transmission time window W of the first signal and the PF or PO location. Where W is related to the number of SSBs in the broadcast message from the network device, or W is related to the period R of the beam sweep in which the SSBs are transmitted, e.g., W ═ R slots, or W ═ R symbols, and in possible embodiments, R is the same as S. The terminal equipment receives the first signal in the sending time window, when the terminal equipment receives the first signal, the terminal equipment receives the PDCCH after deltaT, and if the terminal equipment does not receive the first signal, the terminal equipment stops monitoring the PDCCH.

In summary, in the embodiments of the present invention, the terminal device starts receiving the paging message at a first interval after receiving a first signal, where the first signal instructs the terminal device to perform an energy saving operation, which may be regarded as an energy saving signal, that is, a paging location is determined according to a receiving time of the energy saving signal, so as to receive the paging message at the paging location. Therefore, even if the beam directions with different time slot lengths exist in the beam scanning process, the receiving time of the energy-saving signal is flexibly adjusted, and the paging position is flexibly adjusted, so that the flexibility of the terminal equipment for receiving the paging message is improved.
