Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions in the embodiments of the present application will be clearly and completely described in the following in conjunction with the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

For ease of understanding, concepts related to the embodiments of the present application will be described first.

1. Anchor point district (Anchor cell)

In a communication network, a cell that provides a large coverage and cannot be turned off is called an anchor cell, and may also be called an anchor carrier (anchor carrier), a first type carrier, a first type cell, a primary carrier (primary carrier), or a primary cell (PCell).

2. Non anchor point cell (non-anchor cell)

In a communication network, a cell that has a small coverage area and provides high-speed data transmission service and can be closed according to a network load condition is called a non-anchor cell, and may also be called a non-anchor carrier (non-anchor carrier), a second carrier, a second cell, a secondary carrier (secondary carrier), or a secondary cell (SCell).

3. Random access procedure

Random access procedure as shown in fig. 1, the terminal device first completes downlink synchronization by reading a master information block (master information block, MIB) and a system information block (system information block, SIB) 1. By reading SIB1, the terminal device determines the resources for transmitting the preamble to the network device to indicate its intention to access the network, and transmits a random access preamble (Msg 1) to the network device. If the network device receives Msg1 correctly, it will send a random access response message (Msg 2) to the terminal device scrambled with a random access radio network temporary identity (random access radio network temporary identity, RA-RNTI). After transmitting the Msg1, the terminal device may monitor the Msg2 from the network device using the RA-RNTI to descramble the message.

Msg2 may contain a Time Advance (TA), a temporary cell radio network temporary identity (temporary cell radio network temporary identity, TC-RNTI), power adjustments, and a resource indication for the terminal device to transmit Mgs. The terminal device then sends its identity and radio resource control protocol (radio resource control, RRC) connection request (Msg 3) to the network device via an uplink scheduling indication in Msg 2. Finally, the network device may notify the terminal device of the completion of the initial access procedure through Msg4, otherwise, the terminal device may determine that the initial access procedure fails.

4. Physical random access channel transmission opportunity

Either physical random access channel transmission occasion or physical random access channel occasion, abbreviated as RO.

In a New Radio (NR) system, a network device may configure ROs for multiple frequency division multiplexing (frequency division multiplex, FDM) in the frequency domain.

The terminal device can acquire relevant configuration of the RO through SIB message, wherein the relevant configuration comprises the cycle size of the RO, the number of the RO in the time domain in one physical random access channel (physical random access channel, PRACH) cycle, the number of the RO multiplexed in the frequency domain (msg 1-FDM), the number of the synchronous signal blocks (synchronization signal/physical broadcast signal block, SSB) associated with each RO and the like.

For the network device, the network device needs to continuously detect the Msg1 sent by the terminal device on the configured RO resource, so as to ensure that the Msg1 sent by the terminal device can be timely received.

5. Paging message (paging)

The paging message functions include: (1) Sending a call request to the terminal equipment in the RRC idle state; (2) Notifying the terminal equipment in an RRC idle state or an inactive state and in the RRC; the terminal equipment in a connection state changes system information; (3) The method comprises the steps of indicating a terminal device to start receiving a primary notification and/or a secondary notification of an earthquake tsunami warning system (earthquake and tsunami warning system, ETWS); the terminal device is instructed to start receiving public warning system (commercial mobile alert system, CMAS) notifications.

If the terminal equipment is paged or the system information is updated or earthquake and tsunami occurs, the base station firstly transmits a wake-up signal, and after the terminal equipment detects the wake-up signal, the terminal equipment monitors the paging PDCCH and receives the paging message, otherwise, the terminal equipment always keeps a sleep state so as to achieve the purpose of saving electricity.

In NR, the terminal device may use discontinuous reception (discontinuous reception, DRX) in RRC idle state and RRC inactive state in order to reduce power consumption. The terminal device periodically (the period is a DRX cycle) listens to Paging Occasions (POs). The relationship between DRX cycle and PO is shown in fig. 2.

In addition, the terminal device needs to complete time-frequency synchronization and automatic gain control adjustment using a reference signal (e.g., SSB) before receiving the paging message. From the network device perspective, once a terminal device is paged, the network device needs to send paging messages over the entire tracking area, that is, the base station of the entire tracking area needs to send paging messages (because the terminal device is in an idle state or inactive state, the network device does not know the location of the terminal device, and can only page over the entire tracking area).

6. Paging advance indication (paging early indication, PEI)

In order to save the power consumption of the terminal device, in the DRX scenario, one or more POs are associated with one PEI, as shown in fig. 3, one PO is associated with one PEI; before monitoring the PO, the terminal equipment needs to receive PEI to determine whether the PO associated with the PEI needs to be monitored, so as to achieve the purpose of energy saving, wherein the PEI can be downlink control information or a sequence.

The terminal equipment is in an RRC idle state or an RRC inactive state when receiving the PEI, the PEI can carry grouping information, namely the PEI can indicate which terminal equipment groups need to be awakened (the terminal equipment associated with one PO is divided into a plurality of terminal equipment groups), and the terminal equipment determines whether the terminal equipment needs to be awakened according to the indication information corresponding to the terminal equipment groups.

7. Energy consumption of network equipment

The power consumption of the network device includes static power consumption and dynamic power consumption. The static energy consumption mainly comprises static receiving energy consumption and static sending energy consumption, wherein the static receiving energy consumption mainly comprises energy consumption generated by the network equipment for receiving the Msg1 on the configured random access resource, and the static sending energy consumption mainly comprises energy consumption generated by sending a reference signal, paging information, system information and the like. Dynamic energy consumption indicates energy consumption that varies with traffic and data volume changes, such as data transmission and the like.

8. Network equipment

Including but not limited to: an evolved base station (evolutional node B, eNB or eNodeB) in long term evolution (long term evolution, LTE), a base station (gndeb or gNB) or TRP in new air interface technology (new radio, NR), a base station in a subsequent evolution system, an access node in a wireless fidelity (wireless fidelity, wiFi) system, a wireless relay node, a wireless backhaul node, etc. The base station may be: macro base station, micro base station, pico base station, small station, relay station, or balloon station, etc. Multiple base stations may support networks of the same technology as mentioned above, or may support networks of different technologies as mentioned above.

The terminal device may also be fixed or mobile.

In order to facilitate understanding, an application scenario to which the embodiment of the present application is applicable is described below with reference to fig. 4.

Fig. 4 is a schematic diagram of an application scenario provided in an embodiment of the present application. Referring to fig. 4, the network device 401, the network device 402, the network device 403, the network device 404, and the terminal device 405 are included.

The area covered by the network device 401 is the anchor cell. The areas covered by each of network device 402, network device 403, and network device 404 are non-anchor cells. Network device 402, network device 403, and network device 404 are located within the coverage area of network device 401, and may be turned on or off as desired under the control of network device 401. The terminal device 405 may establish a connection relationship with any one of the network device 401, the network device 402, the network device 403, and the network device 404. Network device 402, network device 403, and network device 404 may provide high-speed data transmission services to terminal device 405 within respective coverage areas.

Network device 401 needs to carry MIB and SIBs to support cell search and system information transmission. Network device 402, network device 403, or network device 404 need not carry MIB and SIB if it is only for data load balancing purposes; if paging, random access, and radio resource management (radio resource management, RRM) measurements, etc. need to be supported, MIB and SIB are still needed to support time-frequency synchronization and RRM measurements by the terminal device.

In the 5G network, in order to ensure the access of the terminal equipment, the anchor point cell and all non-anchor point cells need to continuously transmit reference signals, so that the terminal equipment can measure the reference signals transmitted by the anchor point cell and the non-anchor point cell, and select one cell for random access based on a measurement result. Correspondingly, the anchor cell and all non-anchor cells need to detect the random access request sent by the terminal equipment on the pre-configured random access resource. Resulting in higher power consumption on the network side.

In order to solve the technical problem, the anchor point cell in the embodiment of the present application indicates a part of non-anchor point cells to send a reference signal through the indication information, so that the terminal device measures the part of non-anchor point cells and selects a cell for random access in the part of non-anchor point cells. Therefore, only part of network equipment corresponding to the non-anchor cells is required to continuously send the reference signal and detect the Msg1, and the static energy consumption of the network equipment is reduced.

The following describes the technical scheme shown in the present application by specific examples. It should be noted that the following embodiments may exist independently or may be combined with each other, and for the same or similar content, the description will not be repeated in different embodiments.

Fig. 5 is a flow chart of a communication method according to an embodiment of the present application. Referring to fig. 5, the method may include:

and S501, the network equipment corresponding to the anchor point cell sends indication information to the terminal equipment, wherein the indication information is used for indicating part of non-anchor point cells in the plurality of non-anchor point cells.

A plurality of non-anchor cells are within the coverage of the anchor cell.

A portion of the non-anchor cells are non-anchor cells of the plurality of non-anchor cells configured to transmit reference signals and receive random access request messages.

The indication information may directly indicate the identity of a part of non-anchor cells; part of the non-anchor cells may also be indicated indirectly.

Wherein the indirect indication may be used to: dividing a plurality of non-anchor cells into M non-anchor cell groups in advance, wherein each non-anchor cell group comprises at least one non-anchor cell; m is an integer greater than 1; the indication information indicates at least one target non-anchor cell group of the M non-anchor cell groups; the partial non-anchor cells include non-anchor cells in at least one target non-anchor cell group.

For example, if there are 6 non-anchor cells, cell 1, cell 2, cell 3, cell 4, cell 5, and cell 6, respectively; dividing the cell into 2 non-anchor cell groups A and B, wherein the non-anchor cell group A comprises a cell 1, a cell 2 and a cell 3, and the non-anchor cell group B comprises a cell 4, a cell 5 and a cell 6; the indication information may indicate that the non-anchor cell group a is a target non-anchor cell group, and then the partial non-anchor cells refer to cell 1, cell 2, and cell 3. If there is no packet information in advance, the indication information may also directly indicate the identities of cell 1, cell 2 and cell 3.

S502, the terminal equipment measures the reference signals sent by the network equipment corresponding to part of non-anchor cells according to the indication information, and a measurement result of part of non-anchor cells is obtained.

The reference signal may be sent by the network device corresponding to the anchor cell indicating a portion of the network devices corresponding to the non-anchor cell.

The reference signal may be an SSB, a channel state information reference signal (channel state information-reference signal, CSI-RS), a tracking reference signal (tracking reference signal, TRS), or other newly designed reference signal.

The measurement result may refer to a reference signal received power (reference signal receiving power, RSRP).

If the indication information does not indicate part of the non-anchor cells, the terminal equipment needs to measure the reference signals sent by the network equipment corresponding to all the non-anchor cells in the coverage range of the anchor cells.

S503, the network equipment corresponding to the anchor point cell sends a first paging message to the terminal equipment.

The transmission time of the first paging message is later than the transmission time of the indication information.

The first paging message is used for instructing the terminal device to initiate a random access procedure.

S504, if the measurement result of part of non-anchor cells indicates that a first target non-anchor cell meeting the cell residence condition exists in part of non-anchor cells, the terminal equipment sends a random access request message to the network equipment corresponding to the first target non-anchor cell.

The cell camping condition may be satisfied in that the reference signal quality of the cell is greater than a preset threshold.

The first target non-anchor cell may be determined among the partial non-anchor cells based on whether the RSRP is greater than a preset threshold. If there are a plurality of RSRPs larger than the preset threshold, the cell with the largest RSRP can be determined as the first non-anchor cell.

In the embodiment shown in fig. 5, the network device corresponding to the anchor cell sends indication information to the terminal device, where the indication information is used to indicate a part of non-anchor cells in the multiple non-anchor cells; the terminal equipment measures the reference signals sent by the network equipment corresponding to part of non-anchor cells according to the indication information to obtain measurement results of part of non-anchor cells; after receiving the first paging message, if the measurement result of part of non-anchor cells indicates that a first target non-anchor cell meeting the cell residence condition exists in part of non-anchor cells, the terminal equipment sends a random access request message to the network equipment corresponding to the first target non-anchor cell. In a plurality of network devices, only part of network devices corresponding to non-anchor cells continuously transmit reference signals and receive random access request messages transmitted by terminal devices, so that static energy consumption of a network side is reduced; meanwhile, the terminal equipment only measures the reference signals sent by the network equipment corresponding to part of non-anchor cells, so that the energy consumption of the terminal equipment is reduced.

The above communication method will be described in detail with reference to the embodiment shown in fig. 6, based on the embodiment shown in fig. 5.

Fig. 6 is a flow chart of another communication method according to an embodiment of the present application. Referring to fig. 6, the method may include:

s601, network equipment corresponding to an anchor point cell sends system information to terminal equipment.

The system information includes packet information of a plurality of non-anchor cells.

And S602, the network equipment corresponding to the anchor point cell sends indication information to the terminal equipment, wherein the indication information is used for indicating part of non-anchor point cells in the plurality of non-anchor point cells.

The network device corresponding to the anchor cell may send the indication information to the terminal device in several ways:

mode one: the network equipment corresponding to the anchor point cell sends paging advance indication information to the terminal equipment, wherein the paging advance indication information comprises the indication information;

mode two: the network equipment corresponding to the anchor point cell sends paging downlink control information to the terminal equipment, wherein the paging downlink control information comprises the indication information;

mode three: and the network equipment corresponding to the anchor point cell sends a second paging message to the terminal equipment, wherein the second paging message comprises the indication information.

The indication information may include a first information field composed of a plurality of bits, each bit corresponding to one or more non-anchor cell groups of the M non-anchor cell groups; the value of each bit in the first information field is used for indicating whether the one or more non-anchor cell groups corresponding to the bit are the target non-anchor cell groups.

For example, the network device corresponding to the anchor cell indicates 4 non-anchor cell groups through the system information, the bit field in the indication information for indicating the target cell group has 4 bits, one bit corresponds to one non-anchor cell group, and if the bit field in the indication information received by the terminal device for indicating the target cell group has a value of 1100 (as shown in the following table), it indicates that the non-anchor cell group 1 and the non-anchor cell group 2 are the target non-anchor cell group, and the non-anchor cell in the target non-anchor cell group is a non-anchor cell in a part of the non-anchor cells.

1	1	0	0
				Non-anchor cell group 1	Non-anchor cell group 2	Non-anchor cell group 3	Non-anchor cell group 4

The indication information may also include a second information field composed of a plurality of bits, where values of the plurality of bits in the second information field are used to indicate an identification of the at least one target non-anchor cell group.

For example, the network device corresponding to the anchor cell indicates 4 non-anchor cell groups through the system information, the bit field in the indication information for indicating the target cell group has 2 bits, the corresponding relation between the code point in the bit field for indicating the target cell group and the non-anchor cell group is as follows, if the bit field in the indication information received by the terminal device for indicating the target cell group has a value of 11, the non-anchor cell group 4 is indicated as the target non-anchor cell group, and the non-anchor cell in the target non-anchor cell group is a non-anchor cell in a part of the non-anchor cells.

00	01	10	11
				Non-anchor cell group 1	Non-anchor cell group 2	Non-anchor cell group 3	Non-anchor cell group 4

And S603, the terminal equipment measures the reference signals sent by the network equipment corresponding to the partial non-anchor cells according to the indication information to obtain measurement results of the partial non-anchor cells.

The network device corresponding to a part of non-anchor cells may send the reference signal under the control of the network device corresponding to the anchor cell. The following method can be adopted:

determining the partial non-anchor cells in the plurality of non-anchor cells; and sending third control information to the partial non-anchor cells, wherein the third control information is used for indicating network equipment corresponding to the partial non-anchor cells to send reference signals and receive random access request messages.

The control information may be control information of a single non-anchor cell or control information of a plurality of non-anchor cells.

For example, the number of non-anchor cells is 4, and cell 1, cell 2, cell 3, and cell 4, respectively, are located within the coverage of the anchor cell. The network equipment corresponding to the anchor point cell sends control information to the cell 1, and controls the cell 1 to send a reference signal and receive a random access request message; the network equipment corresponding to the anchor point cell sends control information to the cell 2, and controls the cell 2 to send a reference signal and receive a random access request message; the network equipment corresponding to the anchor point cell sends control information to the cell 3, and the cell 3 is controlled to stop sending the reference signal and stop receiving the random access request message; the network device corresponding to the anchor cell sends control information to the cell 4, and the control cell 4 stops sending the reference signal and stops receiving the random access request message.

For another example, the number of non-anchor cells is 4, and the number of non-anchor cells, namely cell 1, cell 2, cell 3 and cell 4, is within the coverage of the anchor cell. The network equipment corresponding to the anchor point cell sends control information to the cell 1, the cell 2, the cell 3 and the cell 4, and the non-anchor point cell determines whether to send or stop sending the reference signal according to the self identification and the control information, specifically, the control information can be shown in the following table, and the cell 1 and the cell 2 can send the reference signal according to the control information and receive the random access request message; cell 3 and cell 4 may stop transmitting the reference signal and stop receiving the random access request message according to the control information.

Cell 1	Cell 2	Cell 3	Cell 4
				Start to	Start to	Stop of	Stop of

The control information may individually instruct the non-anchor cell to start transmitting the reference signal or stop transmitting the reference signal; the control information may also indicate both the time when a single non-anchor cell starts transmitting reference signals and the time when reference signals stop transmitting.

For example, the network device corresponding to the non-anchor cell a receives the control information a sent by the network device corresponding to the anchor cell, sends a reference signal according to the control information a, and receives a random access request message; after a period of time, the network device corresponding to the non-anchor cell A receives the control information B sent by the network device corresponding to the anchor cell, and stops sending the reference signal and stopping receiving the random access request message according to the control information B.

For another example, the network device corresponding to the non-anchor cell a receives control information sent by the network device corresponding to the anchor cell, where the control information indicates that the network device corresponding to the non-anchor cell a starts to send a reference signal and receive a random access request message at time T1, and stops sending the reference signal and stops receiving the random access request message at time T2.

The network device corresponding to the anchor cell may send control information to the network device corresponding to the non-anchor cell through the Xn port.

The network devices corresponding to part of non-anchor cells can also be controlled by the network devices corresponding to the anchor cells, and continuously send reference signals and receive random access request messages.

S604, the network equipment corresponding to the anchor point cell sends a first paging message to the terminal equipment.

It should be noted that, the execution of S604 may refer to the execution of S503, which is not described herein.

S605, the measurement result of the partial non-anchor cell indicates whether there is a first target non-anchor cell satisfying the cell residence condition in the partial non-anchor cell.

If yes, then S606 is performed.

If not, S607 is performed, or S608 is performed.

S606, sending a random access request message to the network equipment corresponding to the first target non-anchor cell.

It should be noted that, the execution process of S606 may refer to the execution process of S504, which is not described herein.

S607, sending random access request message to network equipment corresponding to the anchor cell.

The network device corresponding to the anchor cell may always receive the random access request information sent by the terminal device.

And S608, the network equipment corresponding to the anchor point cell sends first control information to the network equipment corresponding to the rest of the non-anchor point cells at a second moment, wherein the first control information is used for indicating the network equipment corresponding to the rest of the non-anchor point cells to send reference signals and indicating the network equipment corresponding to the rest of the non-anchor point cells to receive random access request messages sent by the terminal equipment.

After the network equipment corresponding to the anchor point cell sends the first paging message, if the terminal equipment is detected to not finish the random access process within the second preset time, at the second moment, first control information is sent to the network equipment corresponding to the remaining non-anchor point cell, wherein the first control information is used for indicating the network equipment corresponding to the remaining non-anchor point cell to send a reference signal and indicating the network equipment corresponding to the remaining non-anchor point cell to receive a random access request message sent by the terminal equipment. Wherein, the network device only tries to receive the random access request message sent by the terminal device, and is not necessarily capable of receiving the random access request message; the time interval between the second time and the sending time of the first paging message is greater than or equal to a second preset duration.

The second preset time period is longer than or equal to the time required by the terminal equipment to complete a random access process.

For example, the second preset duration may be a time required for the terminal device to complete the random access procedure once, or may be a time required for the terminal device to complete the random access procedure three times.

The remaining non-anchor cells are other non-anchor cells of the plurality of non-anchor cells except for a portion of the non-anchor cells.

For example, there are a total of 4 non-anchor cells, cell 1, cell 2, cell 3, and cell 4, where cell 1 and cell 2 are part of the non-anchor cells and then cell 3 and cell 4 are the remaining non-anchor cells.

After the network equipment corresponding to the anchor point cell delays the second preset time, the network equipment corresponding to the rest non-anchor point cell is controlled to send the reference signal and receive the random access request message from the second moment, so that the static energy consumption of the rest non-anchor point cell can be further reduced.

A timer can be set for the remaining non-anchor cells at the network device corresponding to the anchor cell, a second timer is started at a second moment, if the second timer is overtime, second control information is sent to the network device corresponding to the remaining non-anchor cells, and the second control information is used for indicating the remaining non-anchor cells to stop sending reference signals and indicating the remaining non-anchor cells to stop receiving random access request messages sent by the terminal device.

For example, if the network device corresponding to the anchor cell detects that the terminal device does not complete the random access process within the second preset time after sending the first paging message, the network device corresponding to the anchor cell starts to control the remaining non-anchor cell to send the reference signal from the second moment, controls the remaining non-anchor cell to receive the random access request message sent by the terminal device, and triggers a timer, and during the running period of the timer, the remaining non-anchor cell needs to send the reference signal and receive the random access request message sent by the terminal device, and if the timer is overtime, the remaining non-anchor cell stops sending the reference signal and receives the random access request message sent by the terminal device.

By setting the timer in the network device corresponding to the anchor cell, the rest non-anchor cells can be prevented from always sending the reference signal and receiving the random access request message, and the static energy consumption of the network device corresponding to the rest non-anchor cells is further reduced.

The first control information and the second control information may be identical to the third control information.

In order to facilitate understanding, a process of controlling the network device corresponding to the remaining non-anchor cells by the network device corresponding to the anchor cell in the present application will be described in detail with reference to fig. 7 by taking the number of remaining non-anchor cells as an example. As shown in fig. 7, the network device corresponding to the anchor cell sends first control information to the network devices corresponding to the remaining non-anchor cells, and the network devices corresponding to the remaining non-anchor cells send reference signals and receive random access request messages sent by the terminal device according to the first control information; after a period of time, the network equipment corresponding to the anchor point cell sends second control information to the network equipment corresponding to the rest of non-anchor point cells, and the network equipment corresponding to the rest of non-anchor point cells stops sending the reference signal and stops receiving the random access request message sent by the terminal equipment according to the second control information.

S609, measuring the reference signals of the rest non-anchor cells to obtain the measurement results of the rest non-anchor cells.

The reference signals of the remaining non-anchor cells may be measured to obtain measurement results of the remaining non-anchor cells by:

measuring reference signals of the remaining non-anchor cells from a first moment to obtain measurement results of the remaining non-anchor cells; wherein, the time interval between the first time and the receiving time of the first paging message is greater than or equal to a first preset duration.

The first preset time period may be a sum of the first time period and the second time period; the first time length is the time length required by the terminal equipment to complete a random access process, and the second time length is the time length required by the terminal equipment to perform carrier switching.

For example, the time interval between the first time and the time of receiving the first paging message may be a sum of a time length required for the terminal device to complete one random access procedure and a time length required for the terminal device to perform carrier switching; or the sum of the time length required by the terminal equipment to complete the random access process for a plurality of times and the time length required by the terminal equipment to perform carrier switching.

If the terminal device directly measures the reference signal of the remaining non-anchor cells after receiving the first paging message, the remaining non-anchor cells do not send the reference signal at this time, the terminal device cannot receive the reference signal, which results in measurement failure and increases the energy consumption of the terminal device. Therefore, the terminal equipment can delay the measurement of the reference signals of the rest non-anchor cells for the first preset time length, and the energy consumption of the terminal equipment can be reduced.

And a first timer can be started at the first moment, and if the first timer is overtime, the measurement of the reference signals of the rest non-anchor cells is stopped.

A timer may be set in the terminal device, after the terminal device receives the first paging message, the terminal device delays the first duration and the second duration, and triggers the timer, and during the running period of the timer, the terminal device measures the reference signals sent by the network devices corresponding to the remaining non-anchor cells.

The units of the first duration and the second duration may be milliseconds, frames, subframes, slots, etc.

By setting the timer in the terminal device, the terminal device can be prevented from receiving the reference signal all the time and measuring the reference signal, and the energy consumption of the terminal device is further reduced.

S610, the measurement result of the remaining non-anchor cells indicates whether there is a second target non-anchor cell satisfying the cell residence condition in the remaining non-anchor cells.

If yes, S611 is executed.

If not, then S607 is performed.

S611, a random access request message is sent to the network equipment corresponding to the second target non-anchor cell.

It should be noted that, the execution of S611 may refer to the execution of S606, which is not described herein.

In the embodiment shown in fig. 6, if the measurement result of the part of non-anchor cells indicates that the part of non-anchor cells does not have the first target non-anchor cell satisfying the cell residence condition, the terminal device may send a random access request message to the network device corresponding to the anchor cell; and the terminal equipment can also measure the reference signals of the remaining non-anchor cells to obtain measurement results of the remaining non-anchor cells, and if the measurement results of the remaining non-anchor cells indicate that a second target non-anchor cell meeting the cell residence condition exists in the remaining non-anchor cells, the terminal equipment sends a random access request message to network equipment corresponding to the second target non-anchor cell, otherwise, the terminal equipment sends the random access request message to the network equipment corresponding to the anchor cell. The random access failure caused by the fact that no proper non-anchor cells exist in part of non-anchor cells is avoided, and the success rate of the random access is improved.

On the basis of any of the above embodiments, the above communication method is exemplified below with reference to fig. 8 to 10.

Example 1

If there are 4 non-anchor cells in the coverage area of the network device corresponding to the anchor cell, it is divided into two groups { C1, C2} and { C3, C4}.

The network equipment corresponding to the anchor point cell transmits the non-anchor point cell grouping information to the terminal equipment through the system information, and the terminal equipment determines the grouping information of the non-anchor point cell through receiving the system information transmitted by the anchor point cell.

Then, the network device corresponding to the anchor cell indicates that the target non-anchor cell group to be measured by the terminal device is { C1, C2}, through paging advance indication information (PEI), paging downlink control information or a second paging message, as shown in fig. 8, the network device corresponding to C1 and C2 needs to transmit a reference signal and detect Msg1, after receiving a first paging message transmitted by the network device corresponding to the anchor cell, the terminal device measures the reference signal transmitted by the network device corresponding to C1 and C2, and if there is at least one RSRP value of the non-anchor cell greater than a threshold set by the network, it is indicated that there is a suitable non-anchor cell in C1 and C2, and the terminal device can initiate a random access procedure to the network device corresponding to the determined suitable non-anchor cell; if the RSRP values of C1 and C2 are smaller than the threshold set by the network, it is indicated that there is no suitable non-anchor cell in C1 and C2, and the terminal device may initiate a random access procedure to the network device corresponding to the anchor cell.

Only part of network equipment corresponding to the non-anchor cells continuously transmits reference signals and receives random access request messages transmitted by the terminal equipment, so that the static energy consumption of the network side is reduced.

Example 2

Then, the network device corresponding to the anchor cell indicates that the target non-anchor cell group to be measured by the terminal device is { C1, C2} through the paging advance indication information (PEI), and then, as shown in fig. 9, the network device corresponding to C1 and C2 needs to transmit a reference signal and detect Msg1, after receiving the first paging message transmitted by the network device corresponding to the anchor cell, the terminal device measures the reference signal transmitted by the network device corresponding to C1 and C2, where the RSRP values of C1 and C2 are smaller than the threshold set by the network, to indicate that no suitable non-anchor cell exists in C1 and C2.

After the network device corresponding to the anchor cell sends the first paging message, if the paging terminal device does not complete the random access process within X time units, the network device corresponding to the anchor cell sends first control information to the network device corresponding to the remaining non-anchor cells, where the first control information is used to indicate that the remaining non-anchor cells (C3 and C4) need to send reference signals and need to detect Msg 1.

As shown in fig. 9, after receiving a first paging message sent by a network device corresponding to an anchor cell, a terminal device defers x+y time units to start measurement of remaining non-anchor cells (C3 and C4), where X is a minimum duration required for the terminal device to complete a random access procedure, Y is a duration required for the terminal device to perform carrier switching, that is, defers x+y time units to measure a reference signal sent by a network device corresponding to C3 and C4, and if an RSRP value of at least one non-anchor cell is greater than a threshold set by a network, it is indicated that there is a suitable non-anchor cell in C3 and C4, and the terminal device may initiate a random access procedure to a network device corresponding to the determined suitable non-anchor cell; if the RSRP values of C3 and C4 are smaller than the threshold set by the network, it is indicated that there is no suitable non-anchor cell in C3 and C4, and the terminal device may initiate a random access procedure to the network device corresponding to the anchor cell.

The network equipment corresponding to the rest non-anchor cells does not need to always send reference signals and receive the random access request message sent by the terminal equipment, so that the static energy consumption of the network side is reduced.

Example 3

According to the non-anchor cell grouping information, the network equipment corresponding to the anchor cell determines partial non-anchor cells C1 and C2 from four non-anchor cells C1, C2, C3 and C4; and sending third control information to the network equipment corresponding to C1 and C2, and indicating the network equipment corresponding to C1 and C2 to start sending the reference signal and start receiving the random access request message.

Then, the network device corresponding to the anchor cell indicates that the target non-anchor cell group to be measured by the terminal device is { C1, C2} through the paging advance indication information (PEI), and then, as shown in fig. 10, the network device corresponding to C1 and C2 needs to transmit a reference signal and detect Msg1, after receiving the first paging message transmitted by the network device corresponding to the anchor cell, the terminal device measures the reference signal transmitted by the network device corresponding to C1 and C2, where the RSRP values of C1 and C2 are smaller than the threshold set by the network, to indicate that no suitable non-anchor cell exists in C1 and C2.

As shown in fig. 10, after sending the first paging message, if the paged terminal device does not complete the random access process within X time units, the network device corresponding to the anchor cell sends first control information to the network device corresponding to the remaining non-anchor cell and triggers a timer, and during the running period of the timer, the network device corresponding to the anchor cell needs to control the remaining non-anchor cells (C3 and C4) to send a reference signal and needs to perform Msg1 detection, and the timer times out, the network device corresponding to the anchor cell sends second control information to the network device corresponding to the remaining non-anchor cell, so as to instruct the network device corresponding to the remaining non-anchor cell to stop sending the reference signal and Msg1 detection.

After receiving a first paging message sent by network equipment corresponding to an anchor cell, the terminal equipment delays X+Y time units to start measurement of the rest non-anchor cells (C3 and C4) and triggers a timer, the reference signals sent by the network equipment corresponding to the C3 and C4 are measured during the running period of the timer, the measurement of the reference signals sent by the network equipment corresponding to the C3 and C4 is stopped when the timer is overtime, if at least one RSRP value of the non-anchor cells is larger than a threshold value set by a network, the existence of the proper non-anchor cells in the C3 and C4 is indicated, and the terminal equipment can initiate a random access process to the network equipment corresponding to the determined proper non-anchor cells; if the RSRP values of C3 and C4 are smaller than the threshold set by the network, it is indicated that there is no suitable non-anchor cell in C3 and C4, and the terminal device may initiate a random access procedure to the network device corresponding to the anchor cell.

Compared with example 2, by adding the timer, the time for the network device corresponding to the remaining non-anchor cells to send the reference signal and receive the random access request message sent by the terminal device is further reduced, and the energy consumption of the network side is further reduced.
