Description

Paging monitoring method and terminal

Technical Field

The present invention relates to the field of communications, and in particular, to a paging monitoring method and a terminal.

Background

In NR, because high-frequency transmission is adopted, a beam scanning mode is required for paging a terminal by a network side; for the terminal, the terminal may also support the beam scanning operation. In both LTE and NR systems, each terminal monitors a paging time in a paging cycle, except that there is no problem with beam scanning in the LTE system, where the duration of a paging time is the cycle of a subframe; in the NR system, the duration of one paging occasion is an occupied time of several subframes or a plurality of symbols because the beam scanning operation of the network side is embodied in each paging occasion in which the network side needs to transmit a paging message in a plurality of directions, respectively.

The existing paging mechanism of the LTE system does not consider beam scanning between the network side and the terminal, because the LTE system uses a low frequency band with less loss, the terminal of the whole cell can be paged by adopting an omnidirectional antenna. In the NR system, a high-loss high-frequency band is considered, so that in order to achieve good network coverage, the network side needs to perform beam scanning to achieve coverage capability similar to that of the LTE system; there is also a need for a terminal side that needs to support beam scanning operation in a high frequency spectrum. Thus, LTE is no longer suitable for paging terminals in a cell using omni-directional antennas in a low frequency band, and a system paging scheme needs to perform adaptation improvement related to beam scanning to solve the additional requirement of NR using a high frequency band spectrum. The existing NR system flexibly adjusts the length of the PO (several subframes or multiple symbols, specifically through system message configuration) in order to enable the beam scanning operation on the network side, but there is no conclusion on how the beam scanning on the terminal side is performed, which is a problem that the existing LTE system cannot solve.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

For better understanding of the present invention, first, a SS Block (synchronous Signal Block) according to an embodiment of the present invention is briefly described. SS blocks are NR systems for Broadcast and Synchronization, each of which contains PSS (Primary Synchronization Signal), PBCH (Physical Broadcast Channel), and SSs (Secondary Synchronization Signal) channels. In order to meet the requirement of NR for beam scanning by using high frequency spectrum, SS Block itself performs beam scanning, but the original purpose of designing SS Block is to solve the synchronization and system broadcast problems in high frequency system. The current NR corresponding terminal side beam selection procedure is still pending.

The invention provides a paging monitoring method considering beam scanning of a network side and a terminal, which has the main idea that an SS Block scanning period is multiplexed to enable the terminal to determine a receiving beam of the terminal and complete paging monitoring of the terminal according to the determined beam.

In some embodiments of the present invention, referring to fig. 1, a paging listening method is provided, including:

step 101, before the paging time PO to which the terminal itself belongs, beam scanning is performed in a synchronization signal Block SS Block window closest to the PO to obtain a receiving beam.

Here, the terminal performs beam scanning in an SS Block window closest to a PO before the PO to which the terminal belongs appears, and obtains a receiving beam, thereby multiplexing a scanning period of the SS Block to perform a beam selection process of the terminal, enabling the terminal to incidentally determine the receiving beam thereof, and completing paging listening according to the determined beam.

Step 102, monitoring the paging message in the PO through the receiving beam.

Here, the terminal monitors the paging message in the PO to which the terminal belongs through the reception beam obtained by beam scanning in the SS Block window.

According to the paging monitoring method provided by the embodiment of the invention, the terminal side multiplexes the scanning period of the SS Block to perform the self beam selection process, so that the terminal can determine the receiving beam incidentally and complete the paging monitoring according to the determined beam, the problem that the existing paging mechanism cannot realize the scanning of the beam at the terminal side in a high-frequency scene is solved, and the scanning work of the receiving beam of the terminal is completed together with the scanning process of the SS Block of the system, a new terminal scanning period is not introduced into the system, and the system overhead is reduced.

At present, there is no association matching relationship between the scan cycle of SS Block and the paging cycle of the terminal, and the two are independently configured processes, and in order to implement the process of multiplexing the scan cycle of SS Block by the terminal side to select its own beam, it is necessary to set appropriate constraint conditions for the two, specifically, there are two feasible schemes.

Scheme 1: the PO is directly associated with the SS Block window.

In the scheme, PO and SS Block windows are not configured independently, and the PO and the SS Block windows are directly related.

Specifically, a part of resources in the SS Block window configures SS Block, and the remaining part of resources configures one or more POs, where the one or more POs configurations occur after the SS Block.

Here, the window in which SS Block appears is typically only 5 ms. And forming a synchronous burst set SS burst set by a plurality of SS blocks in the SS Block 5ms window. The period of SS burst set period, i.e., the period in which the SS Block 5ms window appears, may be one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms }. The position where the SS Block 5ms window appears in the period of SS burst set is usually set by an offset (offset). Except that SS Block can occupy a part of resources in the SS Block 5ms window, other residual resources in the window can be used for placing PO, the PO and the SS Block are placed in the SS Block 5ms window after the design, the terminal beam scanning is completed through the SS Block scanning process in the SS Block 5ms window, therefore, the terminal receiving beam direction is determined, and then the monitoring of network side paging messages is completed through monitoring the PO appearing after the SS Block scanning in the SS Block 5ms window.

As shown in fig. 2, a plurality of SS blocks (shown by SSBs) in the SS Block 5ms window form an SS burst set. The SS Block 5ms window includes a plurality of subframes, and each subframe is configured with a PDCCH (Physical Downlink Control Channel). The first part of the resources of the SS Block 5ms window are occupied by SS Block, but the SS Block 5ms window is not completely occupied by SS Block, and the remaining resources can place PO. The terminal can not only complete synchronization and read broadcast information by using an SS Block 5ms window, but also determine the direction of a receiving beam.

Further, all of the one or more POs are configured within the SS Block window; or a part of the last PO of the one or more POs is disposed within the SS Block window, and another part is disposed on a resource outside the SS Block window and adjacent to the SS Block window.

At this time, if the remaining resources in the SS Block window can place the complete PO or POs, the PO or POs is/are all configured in the SS Block window; if the remaining resources in the SS Block window are not enough to place a complete PO or POs, allowing part of the last PO to occupy the subsequent part of resources of the SS Block window, that is, part of the last PO is configured in the SS Block window, another part is configured outside the SS Block window and on the resources adjacent to the SS Block window, and all other POs are configured in the SS Block window.

And if the rest part of resources in the SS Block window can be provided with a plurality of POs, the POs are arranged, and the specific quantity of the arranged POs can be determined according to the system frequency band (directly related to the number of the SS Block), the time-frequency resource range occupied by one SS Block and the time-frequency resource size occupied by one PO.

As shown in fig. 3, a first part of the resources of the SS Block 5ms window are occupied by SS Block and the remaining part of the resources are allocated one or more POs. The PO closest to the right boundary of the SS Block 5ms window does not necessarily occupy the right boundary of the SS Block 5ms window, and the PO closest to the right boundary of the SS Block 5ms window is allowed to occupy the subsequent part of the resource of the SS Block window, that is, the last PO occupies the subsequent part of the resource of the SS Block window. As shown in fig. 4, a part of the last PO is within the SS Block 5ms window, and another part is on the time-frequency resource immediately after the SS Block 5ms window.

It should be noted that some slots of the PO exceed the SS Block window is allowed, but the start slot of the PO must be in the SS Block window and after SS Block scanning is completed, i.e. the PO and SS Block are directly related.

It should be noted that, the embodiment of the present invention does not limit how the terminal determines the PO that the terminal should monitor in one DRX cycle, that is, the problem of the paging packet of the terminal, and may specifically adopt any known manner.

Further, when the number of POs is smaller than the number of SS Block windows, part of the SS Block windows are configured with POs, and the rest of the SS Block windows are not configured with POs.

At this time, if the density of the SS Block window of the system is greater than the PO density, and the number of POs and the number of SSBlock windows are in a one-to-many relationship, there is a case where there is no PO in a part of the SS Block window, that is, there is a part of the SS Block window in the system where POs are arranged, and there is no PO in the remaining SS Block window. The terminal still only monitors the nearest SS Block 5ms window before the PO appears to perform terminal beam scanning, and except the SS Block 5ms window where the PO is located, no PO information exists in other redundant SS Block 5ms windows, namely the SS Block 5ms window belongs to a normal SS Block 5ms window.

Scheme 2: the PO is indirectly associated with the SS Block window.

In the scheme, PO and SS Block windows are independently configured, and PO and SS Block windows are indirectly related.

Specifically, the PO is disposed outside the SS Block window.

Here, the window in which SS Block appears is typically only 5 ms. And a plurality of SS blocks in the SS Block 5ms window form an SS burst set. The period of SS burst set period, i.e., the period in which the SS Block 5ms window appears, may be one of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms }. The position where the SS Block 5ms window appears in the period of SS burst set is usually set by an offset (offset). Specifically, the PO is configured outside the SS Block 5ms window. The SS Block beam scanning process in the SS Block 5ms window can enable the terminal to complete the self receiving beam scanning confirmation work, the SS Block 5ms window is designed in such a way that the terminal is only used for determining the receiving beam direction, and the real PO monitoring work is independent of the fact that the terminal determines the receiving beam direction through the SS Block 5ms window. SS Block and PO are configured relatively independently, and there is no strict corresponding relation between one PO and one SS Block 5ms window. The SS Block 5ms window and PO may be in a one-to-many relationship as shown in fig. 6, although a one-to-one relationship, as shown in fig. 7, or a many-to-one relationship is not excluded. However, in any relationship, it is specified that a terminal belonging to a PO packet only listens to a SS Block 5ms window closest to the PO before the PO to which the terminal belongs appears, and thus, the terminal completes the scanning operation of the reception beam required by the terminal.

It should be noted that which PO of a DRX to which the terminal belongs is agreed by the network side and the terminal in a unified manner, and the calculation method of the present invention is not limited, and any known method may be adopted.

Optionally, a plurality of SS blocks are configured in the SS Block window, and the PO includes a plurality of slots; and the SS Block in the SS Block window corresponds to the time slot in the PO according to a preset corresponding relation.

At this time, no matter in scheme 1 or scheme 2, the SS Block in the SS Block window corresponds to the timeslot in the PO according to the preset corresponding relationship, that is, there is a certain corresponding relationship between the timeslots in the SS Block and the PO, and the terminal only needs to monitor a certain corresponding timeslot in the PO without continuously monitoring the whole PO after completing the monitoring of the SS Block window, thereby saving the power consumption of the terminal.

Optionally, the step 102 includes:

step 1021, determining a target SS Block corresponding to the receiving beam;

step 1022, determining a target time slot in the PO time slot according to the target SS Block and the preset corresponding relationship;

step 1023, listening for paging messages in one or more time slots including the target time slot via the receive beam.

At this time, after the terminal completes SS Block window monitoring, a target SSBlock corresponding to a reception beam is determined, and then a target timeslot is determined in a timeslot of the PO according to a preset correspondence between the target SSBlock and timeslots in the SS Block and the PO, so that only a paging message in one or more timeslots including the target timeslot, such as only the target timeslot or a plurality of timeslots centered on the target timeslot, needs to be monitored through the reception beam, without monitoring the entire PO, thereby achieving the purpose of saving power consumption.

In the embodiment of the present invention, the number of SS blocks in the SS Block window may be determined by the system frequency, and the number of Slot slots in the PO may be configured by the network side. The number of SS blocks may be one of 4, 8, or 64 depending on the frequency. The number of slots in PO is less than or equal to the number of SS blocks because the beam scanned by the slots may be in one direction or a group of directions, and thus there is a problem how to form the slots in SS blocks and PO into correspondence, and several corresponding ways of the embodiments of the present invention are described below.

Scene 1: the number of SS blocks within the SS Block window is the same as the number of slots in the PO.

Optionally, the SS Block window includes Z SS blocks whose identifiers are SSB1 and SSB2 … SSBi … SSBZ in sequence, and the PO includes Z slots whose identifiers are Slot1 and Slot2 … Slot … Slot in sequence; wherein i is a number, and the preset corresponding relationship is that SS blocks in the SS Block windows with the same number i correspond to time slots in the PO; wherein Z is an integer greater than or equal to 1, and i and x are both integers greater than or equal to 1 and less than or equal to Z.

At this time, SS blocks in SS Block windows with the same number i correspond to slots in PO, that is, SSB1 in SS Block windows corresponds to Slot1 in PO, SSB2 in SS Block windows corresponds to Slot2 in PO, … …, and SSBZ in SS Block windows corresponds to Slot z in PO.

The above step 1022 includes:

and acquiring a time slot Slotx corresponding to the target SS Block from the time slot of the PO according to the identification SSBx of the target SS Block and the preset corresponding relation, and taking the time slot Slotx as a target time slot.

Here, SSBx in the SS Block window corresponds to Slotx in PO, and the terminal monitors a paging message in one or more time slots including the slot by using the time slot Slotx as a target time slot through a receiving beam.

At this time, after the terminal determines that the terminal receives the wave beam through the SS Block scanning process, the terminal can wake up at the corresponding Slot time in the PO, and the terminal enters a sleep state in the rest Slot time in the PO, so that the power consumption of the terminal is saved.

As shown in fig. 5, the SS Block window includes 4 SS blocks identified by SSB1, SSB2, SSB3, and SSB4 in sequence, and the PO includes 4 slots identified by Slot1, Slot2, Slot3, and Slot4 in sequence. SSB1 in the SS Block window corresponds to a Slot1 in the PO, SSB2 in the SS Block window corresponds to a Slot2 in the PO, SSB3 in the SS Block window corresponds to a Slot3 in the PO, and SSB4 in the SS Block window corresponds to a Slot4 in the PO. Assuming that the identifier of the target SS Block is SSB2, the terminal takes Slot2 in the PO corresponding to SSB2 as the target timeslot, and the terminal only needs to listen to one or more timeslots including Slot 2.

Scene 2: the number of SS blocks within the SS Block window is greater than the number of slots in the PO.

For example, the number of SS blocks in the SS Block window is 64, and the number of slots in a PO is 8, so that there is a problem that a plurality of SSB beams correspond to one Slot, and the simplest solution is three:

mode 1: the SS Block window comprises Z1 SS blocks which are sequentially identified as SSB1 and SSB2 … SSBj … SSBZ1, the PO comprises Z2 time slots which are sequentially identified as Slot1 and Slot2 … Slot Z2, each time Slot comprises a plurality of pre-divided sub-time slots, and the PO comprises Z1 sub-time slots which are sequentially identified as Slot '1 and Slot' 2 … S lot 'j … Slot' Z1; wherein j is a number, and the preset corresponding relationship is that SS blocks in the SS Block windows with the same number j correspond to sub-slots in the PO; wherein Z1 and Z2 are both integers greater than or equal to 1, Z1 is greater than Z2, and j and x are integers greater than or equal to 1 and less than or equal to Z1.

At this time, the Slot in the PO subdivides the sub-Slot ', so as to achieve the same effect as the above scenario 1, where the SS Block in the SS Block window with the same number j corresponds to the sub-Slot in the PO, that is, the SSB1 in the SSBlock window corresponds to the Slot' 1 in the PO, the SSB2 in the SS Block window corresponds to the Slot '2 in the PO, and … …, and the SSBZ in the SS Block window corresponds to the Slot' Z in the PO.

The above step 1022 includes:

and acquiring a sub-Slot 'x corresponding to the target SS Block in the time Slot of the PO according to the identification SSBx of the target SS Block and the preset corresponding relation, and taking the sub-Slot' x as the target time Slot.

Here, SSBx in the SS Block window corresponds to a sub-Slot ' x in PO, and the terminal monitors a paging message in one or more sub-slots including the sub-Slot ' x through a receive beam with the sub-Slot ' x as a target Slot.

At this time, after the terminal determines that the terminal receives the wave beam through the SS Block scanning process, the terminal can wake up at the corresponding sub-Slot' time in the PO, and the terminal enters a sleep state in the rest of sub-Slot time in the PO, so that the power consumption of the terminal is saved.

Mode 2: the SS Block window comprises Z1 SS blocks which are sequentially identified as SSB1 and SSB2 … SSBj … SSBZ1, and the PO comprises Z2 time slots which are sequentially identified as Slot1 and Slot2 … Slot 2; wherein j is a number; wherein Z1 and Z2 are both integers greater than or equal to 1, Z1 is greater than Z2, j and x are both integers greater than or equal to 1 and less than or equal to Z1, and y is an integer greater than or equal to 1 and less than or equal to Z2.

The above step 1022 includes:

the value of G1 is obtained by the following formula:

G1＝xZ2；(1)

and acquiring a time slot Sloty corresponding to G1 in the time slot of the PO according to the preset corresponding relation, and taking the time slot Sloty as a target time slot.

Wherein the preset corresponding relationship is that SS blocks in the SS Block windows identical to G1 correspond to the same timeslot in the PO.

Here, a beam corresponding to the same SS Block of G1 is placed in a Slot of PO, both the terminal and the network side obey this rule, the terminal acquires the number x corresponding to the identifier SSBx of the target SS Block, then acquires the value of G1 by the above formula 1, then takes the Slot Sloty in PO corresponding to G1 as the target Slot, and the terminal listens to the paging message in one or more slots including the Slot Sloty through the receiving beam.

Note that, the symbol "/" in the above formula 1 indicates a lower integer, for example, 7/3 is 2, and 8/3 is 2.

Mode 3: the SS Block window comprises Z1 SS blocks which are sequentially identified as SSB1 and SSB2 … SSBj … SSBZ1, and the PO comprises Z2 time slots which are sequentially identified as Slot1 and Slot2 … Slot 2; wherein j is a number; wherein Z1 and Z2 are both integers greater than or equal to 1, Z1 is greater than Z2, j and x are integers greater than or equal to 1 and less than or equal to Z1, and Z is an integer greater than or equal to 1 and less than or equal to Z2.
