Next, please refer to fig. 2, which is a flowchart illustrating a method for transmitting paging messages according to an embodiment of the present application. The method is realized through interaction between network equipment and terminal equipment, wherein the network equipment can be a base station under a cellular network or a wireless access point in WIFI.
201: the network equipment configures frequency domain resources for transmitting paging messages;
202: and the network equipment sends paging indication information to the terminal equipment, wherein the paging indication information is used for indicating the frequency domain resource for transmitting the paging message.
203: and the terminal equipment receives the paging indication information and obtains paging information according to the paging indication information.
Hereinafter, 201 will be described in more detail.
The frequency domain resource used for transmitting the paging message may be a Bandwidth (BWP). Typically, a BWP corresponds to a terminal device, and the terminal device is allocated a default BWP bandwidth or subband at the time of initial access. In different embodiments, BWP may consist of a set of consecutive physical resource blocks (Physical Resource Block, PRBs), or BWP may be one subband in one single bandwidth carrier (single wideband carrier), or BWP may also be one CC bandwidth in carrier aggregation (carrier aggregation, CA).
Further, 202 is described in more detail.
In one embodiment, the paging indication information may be a paging reference identifier. It will be appreciated that the above designations, whether paging indication information or paging reference identification, are used to indicate the presence of a paging message or to indicate the location of a paging message, are described by way of example only and are not intended to be limiting of this information. Hereinafter, a paging reference will be described as an example.
In different embodiments, the network device may transmit the paging reference identifier in different signaling, which will be exemplarily described below:
(1) The network device transmits the paging reference identity carried in a synchronization signal block (synchronization signal block, SSB). Specifically, the paging reference identity is carried in a physical broadcast channel (physical broadcast channel, PBCH) of the SSB. In a possible implementation manner, the paging reference identifier carried in the PBCH is used for indicating whether an associated paging message exists, and when the terminal device searches for the SSB, the terminal device can determine whether the searched SSB exists the associated paging message according to the paging reference identifier. In another possible implementation manner, the paging indication information carried in the PBCH is used for indicating the position of the associated paging message, and when the terminal searches for the SSB, the terminal can receive the paging message according to the paging indication information in the paging indication information to the corresponding position. The method comprises the steps of carrying out a first treatment on the surface of the Or alternatively, the process may be performed,
(2) The paging reference identification may also be a residence (camp on available) identification bit in the PBCH, i.e., the network device multiplexes camp on available identification bits in the PBCH to indicate the paging message associated with the SSB. Thus, when the terminal device receives the SSB, it indicates whether there is a paging message associated with the SSB according to the camp on available identification bit of the PBCH therein; or alternatively, the process may be performed,
(3) The paging reference identification may also be transmitted in the remaining system information (remaining system information, RMSI) carried by the carrier. Therefore, the terminal equipment can judge whether the searched RMSI has the associated paging message according to the paging reference identifier in the searched RMSI; or alternatively, the process may be performed,
(4) If the RMSI and paging message are corresponding, that is, if an SSB has an associated RMSI, it indicates that the SSB also has a paging message associated with it, and if an SSB does not have an associated RMSI, it indicates that the SSB does not have an associated paging message. At this time, the paging reference identifier may be an RMSI presence identifier (RMSI presence flag) in the PBCH, i.e., the network device multiplexes the RMSI presence identifier in the PBCH to indicate whether there is a paging message associated with the SSB. Wherein the RMSI presence flag is used to indicate whether the SSB has an associated RMSI. Therefore, the terminal equipment can judge whether the searched SSB has the associated paging message according to the RMSI existence identification of the PBCH in the searched SSB.
Illustratively, the paging reference identification described above may employ "0" and "1" to identify whether an associated paging message exists. The network device may employ a "0" to indicate that there is an associated paging message and a "1" to indicate that there is no associated paging message; alternatively, the network device may employ a "1" to indicate that there is an associated paging message and a "0" to indicate that there is no associated paging message.
In one embodiment, the network device may send the paging message on a default BWP, i.e. the terminal device may search for or receive the paging message on the default BWP when it determines that the paging message is present according to the paging reference identity. The default BWP may be a BWP carrying the SSB or the default BWP may be a BWP carrying the RMSI.
In another embodiment, the network device may indicate a BWP carrying the paging message, i.e. when the terminal device determines that the paging message is present according to the paging reference identity, the indicated BWP may be searched for or received the paging message. The BWP carrying the paging message may be, for example, a BWP carrying a downlink shared physical channel (physical downlink shared channel, PDSCH) of the paging message, or a BWP carrying CORESET scheduling a physical downlink control channel (physical downlink control channel, PDCCH) of the paging message, or also a BWP carrying both a PDSCH of the paging message and a CORESET scheduling PDCCH of the paging message. The network device may indicate the BWP by the paging reference identification or the network device may transmit information indicating the location to the terminal device so that the terminal device may search for the paging message on the indicated BWP. The specific indication method will be described below.
In one embodiment, a network device may transmit multiple SSBs and multiple RMSIs within a system bandwidth and configured to transmit paging messages on one BWP. Referring to fig. 3, the network device is configured with 3 SSBs (SSB 1, SSB2, and SSB 3), and the bandwidth occupied by each SSB is the minimum system bandwidth supported by the terminal device. Each SSB has an associated RMSI (associated RMSI), the network device sends SSB1 and its associated RMSI1 on BWP1, SSB2 and its associated RMSI2 on BWP2, SSB3 and its associated RMSI3 on BWP3, and configures to transmit paging messages only on BWP2. When the terminal searches for SSB1, obtains BWP1 carrying RMSI1 associated with SSB1 according to RMSI indication information indicated in SSB1, finds RMSI1 and finds BWP2 carrying paging message according to paging indication information indicated by RMSI1, so that paging message can be read on the BWP2. Similarly, the terminal device may find BWP2 carrying the paging message according to SSB2, SSB3, respectively RMSI.
The network device also transmits a page to the terminal device at the same time, and the terminal device may acquire BWP for transmitting the paging message according to the frequency offset information. Specifically, the SSB and the RMSI respectively include frequency offset information, where the frequency offset information in the SSB is used to indicate an offset of the BWP carrying the RMSI relative to the BWP where the SSB is located, and the frequency offset information in the RMSI is used to indicate an offset of the BWP carrying the paging information relative to the BWP carrying the RMSI. Thus, when the SSB is searched, the terminal device may find the BWP carrying the RMSI corresponding to the SSB according to the frequency offset information indicated in the searched SSB, and find the BWP carrying the Paging message (Paging) according to the frequency offset information of the BWP for sending Paging relative to the BWP of the RMSI indicated in the RMSI, so that the Paging message may be read on the BWP. This frequency offset information will be exemplarily described below.
It is to be understood that, in different embodiments, the BWP for sending the paging message by the user may be the same as or different from the center frequency point of the BWP carrying the RMSI.
In another embodiment, only one RMSI is configured within the system bandwidth of the network device and the paging message is sent on one BWP. When the network equipment configures a plurality of synchronous signal blocks and configures one RMSI, the paging indication information is carried and sent in the one RMSI; each synchronization signal block includes RMSI indication information, where the RMSI indication information is used to indicate a location of the one RMSI to a terminal device. Referring to fig. 4, the network device is configured with 3 SSBs (SSB 1, SSB2, and SSB 3), and the bandwidth occupied by each SSB is the minimum system bandwidth supported by the terminal device. Wherein the one RMSI is associated with SSB 2. The network device may be configured to transmit RMSI on any BWP, in this embodiment, the network device transmits RMSI on BWP2, it may be understood that in other embodiments, the network device may also be configured to transmit RMSI on BWP1 or BWP3, and in other embodiments, the network device may also transmit RMSI on other BWPs, which is not limited by the present application. In addition, although in fig. 4, the center frequency point of the BWP for transmitting paging information may be the same as the center frequency point of the BWP for carrying RMSI, it is understood that the center frequency point of the BWP for transmitting paging information may be different from the center frequency point of the BWP for carrying RMSI.
The PBCH of each SSB carries RMSI indication information indicating the RMSI location of the one to indicate the one RMSI. When the terminal searches the SSB, the BWP of the associated RMSI is obtained according to the RMSI indicating information indicated in the SSB, and the BWP of the paging message is obtained according to the paging message indicating information indicated in the RMSI. Alternatively, when the PBCH in the SSB carries paging information indication information, the terminal may obtain BWP carrying the paging message according to the paging information indication information.
By indicating the frequency information of the RMSI in the SSB, after the terminal searches for one SSB, the terminal can find the RMSI according to the RMSI indication information of the RMSI indicated by the SSB, without searching for the SSB again and performing the SSB synchronization operation, thereby reducing complexity.
In yet another embodiment, when the network device configures a plurality of synchronization signal blocks and configures one RMSI, only one SSB has an associated RMSI (hereinafter referred to as a first SSB). The paging indication information is carried and sent in the one RMSI; the plurality of synchronization signal blocks comprise a first synchronization signal block associated with the first RMSI, the first synchronization signal block comprises RMSI indication information, and the RMSI indication information is used for indicating the position of the RMSI to terminal equipment; the plurality of synchronization signal blocks are second synchronization signal blocks except for the first synchronization signal block, the second synchronization signal block comprises the first synchronization signal block indication information, and the first synchronization signal block indication information is used for indicating the relative positions of the first synchronization signal block and the second synchronization signal block. When the network device configures a plurality of SSBs, other second SSBs than the first SSB need to carry first synchronization signal block indication information, where the first synchronization signal block indication information is used to indicate a frequency offset from the first SSB, so that the other SSBs can acquire the location of the first SSB. Taking SSB1, SSB2, and SSB3 in fig. 4 as an example, if SSB2 is the first SSB, that is, SSB2 has an associated RMSI, SSB1 and SSB3 respectively carry SSB indication information of SSB 2. Thus, when the terminal device searches for the SSB1, it may acquire the SSB2 according to the SSB indication information carried therein, and further acquire the location of the paging message according to the RMSI associated with the SSB2, thereby searching for or receiving the paging message at the corresponding location. The terminal device also operates similarly when receiving SSB 3.
By indicating the position offset of the SSB with the RMSI indication information in the SSB without the RMSI indication information, after the UE searches for one SSB, the UE can find the BWP of the SSB with the RMSI indication information according to the position offset information in the SSB, thereby finding the position of the BWP for sending the paging message, saving the number of times that the terminal device blindly detects the SSB, and reducing the complexity of the terminal device.
It should be understood that the present embodiment is not limited to the same scenario as the BWP carrying RMSI and the BWP carrying the default SSB, i.e. when the BWP carrying RMSI is different from the BWP carrying each SSB, a certain SSB may still be configured by the network device as the default SSB, so as to be implemented in the manner of the present embodiment.
In yet another embodiment, the network device configures to transmit paging messages on the plurality of BWPs and the paging messages transmitted on the plurality of configured BWPs are not repeated. The terminal obtains the scheduled BWP for sending the paging information according to the paging configuration information in the RMSI, wherein the paging configuration information comprises the following components: the number N of BWPs activated in the present carrier for transmitting paging message n BWP number (paging channel index, PCHI) and/or paging indication information for transmitting the paging message.
Specifically, the PCHI for transmitting the paging message conforms to the following formula:
wherein the method comprises the steps ofN=min (T, nB), nB, T are discontinuous reception (discontinuous reception, DRX) parameters, specifically, T is a DRX cycle (cycle), a UE in a standby (idle) state wakes up every T to listen to a Paging message, nB represents how many Paging Occasions (POs) there are in each DRX cycle, and one PO represents one transmission of a Paging message. The ue_id may be a value obtained by taking a fixed value from the value of any one of the following identifiers: international mobile subscriber identity (international mobile subscriber identity, IMSI), international mobile equipment identity (international mobile equipment identity, IMEI), temporary mobile subscriber identity (temporary mobile subscriber identity, TMSI), radio network temporary identity (radio network temporary identifier, RNTI), international Mobile Subscriber Identity (IMSI)A subscriber identity (international mobile subscriber identity, IMSI), an international mobile equipment identity (international mobile equipment identity, IMEI), a temporary mobile subscriber identity (temporary mobile subscriber identity, TMSI), a radio network temporary identity (radio network temporary identifier, RNTI). The system transmits a paging message on its corresponding BWP according to the terminals of the packet.
Illustratively, the terminal device calculates the number of the BWP scheduled for transmitting the paging message according to the paging message configuration information and the ue_id in RMSI, thereby obtaining the frequency location of the BWP for carrying the paging message. Taking terminal device 1 with ue_id=722 and terminal device 2 with ue_id=739 as an example, t=32, nb=t/2=16, n=min (T, nB) =16, ns=max (1, nB/T) =1, pchi=floor (722/16) mod3=0 of terminal device 1 is obtained, terminal device 2 searches or receives paging messages on the BWP corresponding to PCHI, pchi=floor (739/16) mod3=1 of terminal device 2 is obtained, and terminal device 2 searches or receives paging messages on the BWP corresponding to PCHI.
The network device configures a plurality of BWP in one broadband carrier for transmitting paging message messages, the network device groups users, different user groups correspond to different BWP, and paging messages are not repeated on the BWP, thereby saving paging resources.
The above scheme can be applied to both licensed (licensed) and unlicensed (unlicensed) frequency bands, and the present application is not limited thereto. However, in the application scenario of the unlicensed band, there are competing mechanisms of a plurality of different communication systems, and the unlicensed band will be further described below.
In the unlicensed band, a network device or a terminal device needs to perform listen before talk (listen before talk, LBT) operation before transmitting data in order to ensure fairness.
In the application scenario of the unlicensed band, the paging message is taken as an example and illustrated on a Paging Frame (PF), which may also be called a paging message frame. RMSI may also carry one or more of the following paging frame parameters: a first time offset value, a second time interval, and a paging frame length (POW). The first time offset value is an offset value of the paging frame with respect to a Radio Frame (RF) start time, and may be in units of symbols, or may be in units of slots (slots) or minislots (mini slots). The value of the first time offset value may be zero, which means that the corresponding paging frame is aligned with the start time of the radio frame. Illustratively, when the network device is configured to send paging messages on a plurality of BWP's, each BWP has a different first time offset value P0, P1, P2. The second time interval is the longest time interval for continuously listening for paging messages if no paging message is detected on the corresponding BWP. The second time interval may be in units of symbols, or may be in units of slots (slots) or minislots (mini slots).
When the network device configures RMSI for each SSB, each RMSI carries paging frame parameters transmitted on the BWP where the corresponding SSB is located. When the network device configures only one RMSI for the SSBs, the one RMSI carries paging frame parameters transmitted on BWP where the corresponding SSBs are located, i.e. carries multiple paging frame parameters.
Hereinafter, referring to fig. 6, an example of one RMSI corresponding to a plurality of SSBs will be described. The network device is configured with three SSBs, SSB1, SSB2, and SSB3, respectively, where the bandwidth occupied by each SSB is the minimum bandwidth supported by the terminal device. The three SSBs are transmitted on a plurality of BWP (BWP 1, BWP2 and BWP 3), respectively, which also transmit paging messages. At this time, the one RMSI carries paging frame parameters transmitted on BWP1, BWP2 and BWP3, respectively. POW1 represents the paging frame length of paging frame 1, and paging frames 2, 3 are similar.
As shown, the first time offset value of the paging frame 1 is P0, i.e. the offset value relative to the start time of the radio frame is P0; the first time offset value of the paging frame 2 is P1, i.e. the offset value relative to the start time of the radio frame is P1; the first time offset value of the paging frame 3 is P2, i.e. the offset value with respect to the start time of the radio frame is P2. Wherein P0< P1< P2.
According to the received RMSI, the terminal device listens for paging messages on BWP1, and if no paging message is detected within a second time interval (e.g., the difference between P1 and P2), jumps to listening for paging messages on BWP 2; if the paging message is detected in the second time interval, but the paging message of the user is not detected in the detected paging message, namely the paging message list does not contain the UE_ID of the terminal equipment, continuing to monitor until the POW1 is finished; if the paging message is detected at the second time interval and the paging message of the user is found, the paging message is received.
By configuring paging message frames transmitted on a plurality of BWPs and having different offset durations with respect to radio frames, it is possible to avoid that terminal devices residing on the BWPs cannot receive paging messages because of uncertainty of LBT results, which may not be able to transmit paging messages on a partially unsubscribed BWPs. Therefore, the probability that the terminal equipment detects the paging message in the unlicensed frequency band can be improved, and the communication efficiency is improved.
Illustratively, the paging indication information, the RMSI indication information, and the SSB indication information in the foregoing embodiments may include or be indicated by a frequency offset, and the following is an exemplary description of possible cases of the frequency offset. The frequency offset information is used to indicate frequency location information of BWP.
When the network device and the terminal both have default bandwidths, the frequency offset information may be: (1) Offset of a predetermined frequency point of BWP where paging information is located relative to a start frequency point of BWP carrying SSB or a start frequency point of BWP carrying RMSI; or (2) an offset of a predetermined frequency point of the BWP carrying the paging information with respect to an end frequency point of the BWP carrying the SSB or an end frequency point of the BWP where the RMSI is located; or (3) an offset of a predetermined frequency point of BWP carrying paging information with respect to a center frequency point of BWP carrying SSB or a center frequency point of BWP carrying RMSI. The predetermined frequency point of the BWP carrying the paging information may be a start frequency point, an end frequency point, or a center frequency point.
When the network device and the terminal do not have default bandwidths, the frequency offset information may be: (1) Offset of a start frequency point and an end frequency point of BWP carrying paging information relative to a start frequency point of BWP carrying SSB or a start frequency point of BWP carrying RMSI; or (2) an offset of a start frequency point and an end frequency point of the BWP carrying paging information with respect to an end frequency point of the BWP carrying SSB or an end frequency point of the BWP carrying RMSI; or (3) an offset of a start frequency point and an end frequency point of the BWP carrying paging information with respect to a center frequency point of the BWP carrying SSB or a center point of the BWP carrying RMSI.
If the default bandwidth size convention does not exist in the frequency offset information, the frequency offset information may also be the offset and the bandwidth size of the indicated start frequency point or end frequency point or center frequency point of the BWP relative to the start frequency point of the BWP carrying the SSB or the BWP carrying the RMSI;
optionally, the frequency offset information may be an offset and a bandwidth size of a start frequency point or an end frequency point or a center frequency point of the indicated BWP relative to an end frequency point of the BWP carrying the SSB or the BWP carrying the RMSI;
further optionally, the frequency offset information may be an offset and a bandwidth size of a start frequency point or an end frequency point or a center frequency point of the indicated BWP relative to a center frequency point of the BWP carrying the SSB or the BWP carrying the RMSI;
the frequency point and the bandwidth can be in Hz, KHz, MHz or the like. The granularity of the indication of the offset may be a carrier spacing, RB, or RB group (e.g., 10 RBs).
