Description

Information processing method and device

Technical Field

The embodiments of the present application relate to the field of communication technologies.

Background technique

Since NR (New Radio) base stations need to work in a large bandwidth (such as 100MHz), a large number of ports (64T/64R) and a shorter TTI (transmission time interval) (such as 1ms), the energy consumption of NR base stations in baseband processing, digital front-end and other functions is significantly higher than that of LTE (Long Term Evolution) base stations. In addition, the FR2 (frequency range 2) operating frequency of NR (>6GHz) is higher. The higher the frequency, the greater the path loss of the signal. Therefore, the design principle of NR is to use narrower beams to transmit signals farther. In this way, the number of antenna units used for analog beamforming in NR base stations will increase greatly, which will lead to an increase in the number of RF units and RF channels for transmitting and receiving signals. Each RF channel is equipped with a power amplifier (PA). The energy consumption of PA will account for about 80% of the energy consumption of the entire base station. As the number of PAs increases, the energy consumption of the base station also increases. The current FR1 (frequency range 1) band AAU (active antenna unit) generally uses 192 antenna units and supports 64 channels, which is much larger than the maximum number of 8 channels in LTE.

According to operator statistics, the average energy consumption of an NR base station is more than three times that of an LTE base station. Nearly 50% of the cost of deploying 5G (fifth generation) networks by operators is electricity costs. More importantly, even when there is no business, the energy consumption of NR base stations is still very high, because even when there is no business, the base station still needs to send public signals, such as SSB (synchronization signal block), SIB1 (first system information block), SI (system information) and paging, which greatly reduces the energy efficiency of NR base stations. Energy saving in NR networks is an issue that needs to be addressed urgently.

It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application.

Summary of the invention

In 3GPP Rel-15/Rel-16 (3rd Generation Partnership Project Release 15/Release 16), in the scenario of intra-band carrier aggregation (CA), the secondary cell (SCell) of the terminal equipment (UE) may not send the synchronization signal block (SSB), and the terminal equipment obtains the downlink synchronization of the SCell through the SSB sent by the special cell (SpCell). At the same site, at least one cell sends SSB, and only the cell that sends SSB can be used as the SpCell of the terminal equipment.

In order to save energy in the network, the network can dynamically activate and deactivate the SpCell of the UE according to the traffic volume of the NR cell and its neighboring cells, UE measurement reports and other information. When deactivating a cell, the SSB, SIB1 and SI of the cell are stopped from being sent, and the uplink signal sent by the UE is stopped from being received. In this way, the energy consumption of the SpCell can be saved when the traffic volume is low.

Figure 1 is a schematic diagram of the network energy-saving solution. As shown in Figure 1, when the NR cell enters the energy-saving state, the base station switches the UE to the adjacent cell and informs the adjacent NR base station or LTE base station that the NR cell has entered the energy-saving state. The adjacent NR base station or LTE base station will assume the coverage area and traffic volume of the NR cell. Afterwards, the adjacent NR base station or LTE base station will determine whether to request the NR cell that has entered the energy-saving state to resume normal operation based on its own traffic volume, UE measurement report and other information. For example, when its own traffic volume reaches a certain threshold, it triggers the request to enter the energy-saving state. The NR cell resumes normal operation. When the NR cell resumes normal operation, some UEs that previously switched to the adjacent NR base station or LTE base station may switch back to the NR cell.

The inventors found that in the above scheme, if the NR cell is in the energy-saving state, it means that the cell cannot receive and send any signals, including paging messages, and therefore, the terminal device cannot reside in the cell. When the cell enters the energy-saving state, the UE originally residing in the cell will perform cell reselection to reside in the adjacent cell. When the NR cell dynamically enters the energy-saving state multiple times, the UE will frequently reselect the cell, which will affect the user experience. In addition, the migration of UEs in the energy-saving state cell to the adjacent cell is bound to increase the load level of the adjacent cell, affecting the service quality of the UEs in the adjacent cell.

In response to at least one of the above problems, an embodiment of the present application provides an information processing method and device.

According to one aspect of an embodiment of the present application, there is provided an information processing apparatus, applied to a terminal device, the apparatus comprising:

a receiving unit configured to receive a paging message from the first cell; and

a processing unit, which initiates random access in the second cell or updates system information of the second cell according to the paging;

The first cell is a non-resident cell of the terminal device, and the second cell is a resident cell of the terminal device.

a receiving unit, configured to receive indication information for indicating that the second cell leaves the energy saving state or for indicating that the second cell resumes sending paging, and receive paging from the second cell according to the indication information; and

The second cell is a cell where the terminal device resides.

According to another aspect of an embodiment of the present application, there is provided an information processing apparatus, applied to a network device, the apparatus comprising:

A sending unit, which sends paging to a terminal device in a first cell, so that the terminal device initiates random access in a second cell or updates system information of the second cell according to the paging;

One of the beneficial effects of the embodiments of the present application is that: the terminal device can receive paging from a non-resident cell (first cell), and initiate random access in the resident cell (second cell) or update the system information of the resident cell (second cell) according to the paging. In this way, the resident cell of the terminal device does not need to send paging to the terminal device, which helps to save the energy consumption of the network equipment; and the terminal device can initiate random access in the resident cell or update the system information of the resident cell by receiving paging from the non-resident cell. Therefore, even if the resident cell of the terminal device enters an energy-saving state in which paging is not sent, the terminal device does not have to reselect the cell, thereby avoiding the migration of the terminal device resident in the energy-saving state cell to the adjacent cell to cause service interruption or increase the load level of the adjacent cell, ensuring that the user experience is not reduced when the cell enters the energy-saving state.

The embodiments of the present application are described below in conjunction with the accompanying drawings and specific implementation methods.

Embodiments of the first aspect

An embodiment of the present application provides an information processing method, which is described from the terminal equipment (UE) side.

FIG3 is a schematic diagram of an information processing method according to an embodiment of the present application, which is applied to a terminal device. As shown in FIG3 , the method includes:

301, receiving paging from a first cell;

302. Initiate random access in the second cell or update system information of the second cell according to the paging;

It is worth noting that the above FIG. 3 only schematically illustrates the embodiment of the present application, but the present application is not limited thereto. For example, other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above content, and are not limited to the description of the above FIG. 3.

In some embodiments, the second cell is in an energy-saving state at least when the terminal device receives paging from the first cell. That is, when the cell (second cell) in which the terminal device resides is in an energy-saving state, it does not receive paging from the resident cell, but receives paging from the non-resident cell (first cell). Therefore, when the terminal device (for example, a terminal device in an idle or inactive state) enters an energy-saving state in the resident cell (second cell), it does not need to reselect the cell, but can continue to reside in the second cell, thereby avoiding frequent cell reselection by the terminal device and ensuring user experience.

In some embodiments, the first cell may also be called a reference cell or an anchor cell (Anchor cell), and the second cell may also be called an energy saving (ES) cell, but the embodiments of the present application are not limited to this.

In some embodiments, a cell may have multiple energy-saving modes, and the network device may enable the cell to enter different energy-saving states and maintain communication with the terminal device.

In these energy-saving modes, the common signals (always-on signals) that the network equipment (e.g., base station) still needs to send even when there is no business, such as system broadcast and/or paging, can be reduced or stopped. As a result, the power consumption of the network equipment can be reduced.

For example, the energy saving state may include at least one of the following:

--- Extend the transmission period of common signals, for example, extend the transmission period of SSB (synchronization signal block), SIBs (system information block) and/or paging. For example, make the transmission period of SSB/SIBs longer than that of SSB/SIBs in normal service state (non-energy saving state). In normal service state, the maximum transmission period of SSB is 160ms. In time domain energy saving state, the transmission period of SSB can be longer than 160ms.

---Stop sending common signals, such as stopping the sending of SSB and/or SIBs and/or paging.

---Stop sending dedicated signals,

---Send a simplified common signal, where the simplified common signal may include: an SSB that does not include a master information block (MIB) or a physical broadcast channel (PBCH). For example, the transmitted SSB only includes a synchronization reference signal (SS); or, includes a discovery reference signal (DRS) of the SS, using a DBS instead of the SSB. The present application is not limited to this, and the energy-saving state of the cell may also include other forms of energy-saving states.

In some embodiments, the first cell and the second cell may be different cells of the same network device. That is, after the second cell enters the energy-saving state, the network device to which the second cell belongs may send a paging to a UE residing in the second cell in the first cell of the network device, so that the UE residing in the second cell initiates random access in the second cell or updates the system information of the second cell according to the paging.

In some embodiments, the first cell and the second cell may also belong to different network devices. That is, after the second cell of the second network device enters the energy-saving state, the second network device may notify the first network device adjacent to it, so that the first network device sends a paging in the first cell to the UE residing in the second cell, so that the UE residing in the second cell initiates random access in the second cell or updates the system information of the second cell according to the paging.

In some embodiments, the coverage areas (coverage ranges) of the first cell and the second cell at least partially overlap, thereby ensuring that the UE camped in the second cell can receive paging from the first cell.

In some embodiments, the coverage of the first cell and the second cell may at least partially overlap after the second cell enters the energy-saving state. For example, before the second cell enters the energy-saving state, the coverage of the first cell and the second cell do not overlap; after the second cell enters the energy-saving state, the coverage of the first cell increases, so that the coverage of the first cell and the second cell at least partially overlap.

FIG4 is a schematic diagram of the coverage of the first cell and the second cell of an embodiment of the present application, and FIG5 is another schematic diagram of the coverage of the first cell and the second cell of an embodiment of the present application. FIG4 and FIG5 show the situation where the first cell and the second cell belong to different network devices respectively. As shown in FIG4, before the second cell (indicated by no-ES in FIG4) enters the energy-saving state, the coverage of the first cell cannot cover the coverage of the second cell, that is, the coverage of the first cell and the coverage of the second cell do not overlap. As shown in FIG5, after the second cell (indicated by ES in FIG5) enters the energy-saving state, the second network device to which the second cell belongs notifies the first network device to which the first cell belongs, and the first network device increases the transmission power of the first cell so that the coverage of the first cell includes the original coverage of the second cell (that is, the coverage before the second cell enters the energy-saving state), thereby avoiding coverage holes, and the UE residing in the second cell can receive paging from the first cell.

In some embodiments, when the first cell and the second cell are different cells of the same network device, before the second cell enters the energy-saving state, the coverage of the first cell and the second cell may not overlap; after the second cell enters the energy-saving state, the network device may increase the transmission power of the first cell so that the coverage of the first cell includes the original coverage of the second cell.

However, the present application is not limited thereto, and the coverage of the first cell and the second cell may also overlap before the second cell enters the energy-saving state.

In some embodiments, one first cell may correspond to one or more than one second cell, and/or one second cell may correspond to one or more than one first cell.

In the case where a first cell corresponds to a second cell or a second cell corresponds to a first cell, the area (coverage range) of a first cell may cover the entire original area (coverage range) of a second cell.

In the case that one first cell corresponds to more than one second cell, the area of one first cell may cover at least a part of the original areas of the more than one second cells.

In the case where a second cell corresponds to more than one first cell, the original area of a second cell is covered by more than one first cell respectively, that is, the area of each first cell can cover the entire original area of the second cell; or, the original area of a second cell is covered by more than one first cell together, that is, the area of each first cell covers a part of the original area of the second cell, and the union of the areas of more than one first cells can cover the entire original area of the second cell.

The coverage of the first cell and the second cell is exemplarily described below in conjunction with Figures 6 to 9. Figures 6 to 9 are schematic diagrams of the coverage of the first cell and the second cell in an embodiment of the present application. Figures 6 to 9 both show the coverage of the first cell and the second cell after the second cell enters the energy-saving state.

As shown in FIG. 6 , the original area of the second cell may be covered by the area of a first cell. The second cell corresponds to the first cell, or, in other words, the first cell corresponds to the second cell.

As shown in Figure 7, the area of one first cell covers the entire original area of the second cell-1 and the second cell-2, and the one first cell corresponds to two second cells. In this case, the UE residing in the second cell-1 and the UE residing in the second cell-2 both receive paging from the first cell, and according to the paging, initiate random access on the second cell-1 and the second cell-2, or update the system information of the second cell-1 and the second cell-2, respectively.

As shown in Figure 8, the original area of a second cell is jointly covered by two first cells-1 and first cell-2, that is, the first cell-1 and the first cell-2 respectively cover a part of the original area of the second cell, and the union of the areas of the first cell-1 and the first cell-2 can cover the entire original area of the second cell, and the one second cell corresponds to the two first cells. In this case, the UE residing in the second cell receives paging from the first cell-1 and the first cell-2, and according to the paging, initiates random access on the second cell or updates the system information of the second cell.

As shown in Figure 9, the original area of a second cell is covered by more than one first cell, that is, the first cell-1 and the first cell-2 can cover the entire original area of the second cell, and the first second cell corresponds to the two first cells. In this case, the UE residing in the second cell receives paging from the first cell-1 or the first cell-2, and initiates random access on the second cell or updates the system information of the second cell according to the paging.

In this case, the first cell for the UE to receive paging can be designated by the network, and a first cell can be determined to send paging to the UE residing in the second cell according to the loads, transmission power, etc. of the first cell-1 and the second cell-2.

In some embodiments, the terminal device receives paging from the first cell when at least one of the following conditions is met:

--The terminal device is configured with the cell identifier of the first cell;

--Receive an indication that the second cell stops sending paging messages, for example, receive indication information about the energy saving (ES) state transition of the second cell.

For example, the UE receives indication information that the cell in which the UE resides enters an ES state in which downlink transmission is stopped, and the ES state may include an ES state in which common signals are stopped, common signals and UE-specific signals are stopped, or simplified common signals are sent. For example, the UE may first receive a configuration parameter for not sending paging preconfigured through an RRC message, and then receive an L1/L2 common signaling for activating the configuration parameter. However, the present application is not limited thereto, and an indication that the second cell stops sending paging messages may also be received in other ways.

--The terminal device's capabilities support receiving paging in the first cell.

Among them, the terminal device can report the capability information of supporting receiving paging in non-resident cells to the core network during the initial network attachment or tracking area (TA) update; or, when the RRC connection is established or the wireless network area (RNA) is updated, report the capability information of supporting receiving paging in non-resident cells to the network device that last served the terminal device.

The following is an exemplary description of the reporting of the capability information of the terminal device (UE) in conjunction with Figure 10. Figure 12 is a schematic diagram of the information interaction between the terminal device, the first network device and the core network/network device that last serves the UE in an embodiment of the present application. As shown in Figure 12, the UE reports the capability information of supporting the reception of paging in the non-resident cell to the core network or the network device that last serves the UE. Before the second cell enters the energy-saving state, the second network device normally sends the paging message of the UE in the second cell when receiving the paging indication for the UE; after the second cell enters the energy-saving state, when the second network device receives the paging indication sent by the core network or the network device that last serves the UE, if the paging indication includes the capability information reported by the UE, the second network device stops sending the paging message of the UE in the second cell. On the corresponding UE side, before the second cell enters the energy-saving state, the UE receives the paging message in the second cell where it resides; when the UE receives the indication that the second cell stops sending paging, if the capability of the UE supports receiving paging in the non-resident cell, the UE stops receiving paging in the second cell where it resides and starts receiving paging in the first cell.

In some embodiments, paging may be used to indicate packet arrival and system information update of a UE in an idle/inactive state. Paging may include a paging message and/or a system information update indication (Short Message). When the UE receives a paging message including a paging message, it may initiate random access in the second cell according to the paging message; when the UE receives a paging message including a system information update indication of the second cell, it may update the system information of the second cell according to the system information update indication.

The following is an exemplary description of the manner in which the UE updates the system information of the second cell.

After the second cell enters the energy-saving state, the second cell may stop sending system broadcasts (for example, stop sending MIB/SIBs), or extend the sending cycle of system broadcasts, etc. In order to enable the UE in the idle/inactive state to select and reside in the second cell, the system broadcast of the second cell may be sent by a third cell that overlaps with the coverage of the second cell. The third cell may be the first cell, or another cell different from the first cell.

In some embodiments, after receiving a paging indicating an update of system information of the second cell (i.e., a paging including a system information update indication (Short Message)) from the first cell, the UE receives updated system information of the second cell from the third cell or the second cell.

In some embodiments, after receiving the paging, the terminal device may receive updated system information of the second cell in the next system information update period.

FIG11 is another schematic diagram of information interaction between a terminal device, a first network device, and a second network device in an embodiment of the present application. FIG11 shows a situation where the first cell and the second cell belong to different first network devices and second network devices, respectively. As shown in FIG11 , the terminal device resides in the second cell of the second network device. After the second cell enters the energy-saving state, the second network device sends a system information update paging indication to the first network device, and the first network device sends a paging including a system information update (Short Message) in the first cell to the terminal device residing in the second cell. The second network device sends updated system information of the second cell to the terminal device residing in the second cell in the second cell during the next system information update period in which the first network device sends a paging.

Figure 12 is a schematic diagram of information interaction among a terminal device, a first network device, a second network device, and a third network device in an embodiment of the present application. Figure 12 shows a situation where the first cell, the second cell, and the third cell belong to different first network devices, second network devices, and third network devices, respectively. As shown in Figure 12, the terminal device resides in the second cell of the second network device. After the second cell enters the energy-saving state, the second network device sends a system information update paging indication to the first network device. The first network device sends a paging including a system information update (Short Message) in the first cell to the terminal device residing in the second cell. The second cell sends a system information update indication to the third network device. In the next system information update cycle, the third network device sends updated system information of the second cell to the terminal device residing in the second cell in the third cell.

In some embodiments, when the network device sends a paging in the first cell to indicate a system information update of the second cell, since both the UE residing in the first cell and the UE residing in the second cell will receive the paging, it is necessary to distinguish between the paging indicating the system information update of the first cell and the paging indicating the system information update of the second cell to avoid unnecessary system information update by the UE.

For example, the PDCCH indicating the paging of the second cell system information update can be scrambled by the Paging-Radio Network Temporary Identity (P-RNTI) corresponding to the second cell. In this way, the UE residing in the second cell will only receive the short message scrambled by the specific P-RNTI, while the UE residing in the first cell will not receive the short message scrambled by the P-RNTI specific to the second cell. This can avoid unnecessary system information updates for the UE.

For another example, the paging indicating the update of the system information of the second cell may include information bits for indicating the update of the system information of the second cell. For example, the short message (format as shown in the following table) sent in the first cell adds a new information unit systemInfoModification-NES. If systemInfoModification-NES is set to 1, it means that the system information of the second cell will be updated. If systemInfoModification is set to 1, it means that the system information of the first cell will be updated.

The above exemplifies a method in which the UE receives paging in the first cell and initiates random access in the second cell or updates the system information of the second cell based on the paging. However, the present application is not limited to this. The UE may also receive paging in the second cell. Relevant embodiments of this method will be described in the embodiments of the second aspect.

The above is an exemplary description of the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

It can be seen from the above embodiments that the terminal device can receive paging from a non-resident cell (first cell), and initiate random access in the resident cell (second cell) or update the system information of the resident cell (second cell) according to the paging. In this way, the resident cell of the terminal device does not need to send paging to the terminal device, which helps to save the energy consumption of the network equipment; and, by receiving paging from a non-resident cell, the terminal device can initiate random access in the resident cell or update the system information of the resident cell. Therefore, even if the resident cell of the terminal device enters an energy-saving state in which paging is not sent, the terminal device does not have to reselect the cell, thereby avoiding the migration of the terminal device resident in the energy-saving state cell to the adjacent cell, causing service interruption or increasing the load level of the adjacent cell, and ensuring that the user experience is not reduced when the cell enters the energy-saving state.

Embodiments of the second aspect

The embodiment of the present application provides an information processing method. The description is from the terminal device side, and the same contents as the embodiment of the first aspect are not repeated.

It can be seen from the above embodiments that the terminal device can know the moment when the resident cell leaves the energy-saving state or resumes sending paging, and after the cell leaves the energy-saving state or resumes sending paging, it can receive paging from the resident cell, initiate random access in the resident cell or update the system information of the resident cell, and when the resident cell enters the energy-saving state where paging is not sent, the terminal device does not need to reselect the cell. In this way, it is possible to avoid migrating the terminal device resident in the energy-saving state cell to the adjacent cell to cause service interruption or increase the load level of the adjacent cell, and ensure that the user experience is not reduced when the cell enters the energy-saving state.

In some embodiments, a paging (Short Message) is sent in the first cell to indicate an update of system information of the second cell, and a system information update indication is sent to an adjacent network device, so that the adjacent network device sends updated system information of the second cell in a third cell in the next system information update period.

In some embodiments, the PDCCH of the paging (Short Message) sent in the first cell is scrambled by the P-RNTI corresponding to the second cell; or, the paging (Short Message) sent in the first cell includes an information bit for indicating a system information update of the second cell.

It can be seen from the above embodiments that the terminal device can receive paging from a non-resident cell (first cell), and initiate random access in the resident cell (second cell) or update the system information of the resident cell (second cell) according to the paging. In this way, the resident cell of the terminal device does not need to send paging to the terminal device, which helps to save the energy consumption of the network equipment; and, by receiving paging from a non-resident cell, the terminal device can initiate random access in the resident cell or update the system information of the resident cell. Therefore, even if the resident cell of the terminal device enters an energy-saving state in which paging is not sent, the terminal device does not have to reselect the cell, thereby avoiding the migration of the terminal device resident in the energy-saving state cell to the adjacent cell, which causes service interruption or increases the load level of the adjacent cell, and ensures that the user experience is not reduced when the cell enters the energy-saving state.
