Description

Signal processing method and signal processing device

Technical Field

The present application relates to communication technologies, and in particular, to a signal processing method and a signal processing apparatus.

Background

With the development of technology, User Equipment (UE) such as a mobile phone is more and more widely applied, and a user has a higher requirement on the UE, especially on the cruising ability of the UE, which is related to the power consumption of the UE.

Currently, the UE power saving technology is applied, a Discontinuous Reception (DRX) mechanism is configured for connected, idle, and inactive UEs by a network, a dedicated UE power saving signal is designed at a base station side, and the dedicated UE power saving signal is sent to the UE to inform the UE of detecting a channel in a corresponding DRX cycle or inform the UE of not needing to detect a channel in the corresponding DRX cycle. For example, the dedicated UE power saving signal may include a wakeup signal (WUS) indication, and when the UE receives the UE power saving signal through the corresponding receiving location in the current DRX cycle, the UE may determine to detect a channel in the next DRX cycle of the UE through the dedicated UE power saving signal. If the UE does not receive the UE power reception signal in the current DRX cycle and the corresponding reception location, the UE may determine that it is not necessary to detect a channel in the next DRX cycle of the UE, thereby reducing UE power consumption caused by unnecessary channel detection by the UE.

However, when the base station side designs a dedicated UE power saving signal and transmits the dedicated UE power saving signal to the UE through the corresponding receiving location in the current DRX cycle, both the base station side and the UE side should redesign a set of mechanisms to identify the UE power saving signal. For example: the base station side and the UE side transmit and receive the dedicated UE power saving signal by setting a dedicated transmitting and receiving circuit, which results in higher design complexity of the transmitting and receiving end.

Detailed Description

Referring to fig. 1, fig. 1 is a schematic diagram of an application scenario system framework according to an embodiment of the present disclosure. In order to reduce the power consumption of the terminal device and thereby improve the endurance of the terminal device, currently, a terminal device power saving technology is applied, a network configures a DRX mechanism for the terminal device in a connected state, an idle state and an inactive state, and a dedicated terminal device power saving signal is designed for the terminal device at the network device side to inform the terminal device to monitor a PDCCH in a next DRX cycle or inform the terminal device not to monitor the PDCCH in the next DRX cycle, so that the power loss of the terminal device caused by unnecessary channel detection of the terminal device is reduced, and the endurance of the terminal device is improved. However, when the network device designs a dedicated power saving signal and transmits the dedicated power saving signal to the terminal device in the current DRX cycle, both the network device and the terminal device have to redesign a mechanism to recognize the power reception signal. For example, designing a dedicated transceiver circuit for transceiving the dedicated power saving signal at the network device and the terminal device side results in a high design complexity of the transceiving end.

It should be noted that fig. 1 is a schematic diagram of a system scenario in a communication system, and a network device according to an embodiment of the present invention may be a base station, an access point, or a device in an access network that communicates with a wireless terminal through one or more sectors over an air interface. The base station may be configured to interconvert received air frames and IP packets as a router between the wireless terminal and the rest of the access network, which may include an Internet Protocol (IP) network. The base station may also coordinate management of attributes for the air interface. For example, the base station may be a Base Transceiver Station (BTS) in a global system for mobile communications (GSM) or Code Division Multiple Access (CDMA), may be a base station (NodeB) in a Wideband Code Division Multiple Access (WCDMA), and may be an evolved Node B (eNB or e-NodeB) in LTE, which is not limited in the present application.

In addition, a terminal device may be referred to as a User Equipment (UE), a Mobile Station (MS), a mobile terminal (mobile terminal), an intelligent terminal, and the like, and the terminal device may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal equipment may be a mobile phone (or so-called "cellular" phone), a computer with a mobile terminal, etc., and the terminal equipment may also be a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device and terminal equipment in future NR networks, which exchange voice or data with a radio access network. Description of terminal device: in this application, the terminal device may further include a Relay, and both the terminal device and the base station that can perform data communication may be regarded as the terminal device.

The network architecture and the service scenario described in the embodiment of the present invention are for more clearly illustrating the technical solution of the embodiment of the present invention, and do not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by those skilled in the art that the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.

In view of this, embodiments of the present application provide a signal processing method for reducing the design complexity of the transceiving end. The network equipment determines a WUS or a GTS, wherein the WUS is used for indicating the terminal equipment to monitor the PDCCH in a DRX period, and the GTS is used for indicating the terminal equipment not to monitor the PDCCH in the DRX period; the network equipment informs the terminal equipment of a target position for receiving a reference signal, wherein the target position is used for indicating the receiving position of the terminal equipment for receiving the WUS or the receiving position of the GTS; the network device then transmits the reference signal to the terminal device, the reference signal indicating the WUS or GTS. That is, in the technical solution of the present application, the network device sends an existing reference signal to the terminal device, where the reference signal is used to indicate a WUS or a GTS, and the existing reference signal is used to indicate the WUS to inform the terminal device to monitor a PDCCH in a DRX cycle, or the existing reference signal is used to indicate the GTS to inform the terminal device not to monitor the PDCCH in the DRX cycle. Therefore, the power saving signal of the terminal device is carried by the reference signal in the prior art, and the network device and the terminal device do not need to redesign the dedicated transceiving mechanism of the power saving signal, such as: the network equipment side and the terminal equipment side do not need to design a special transceiving circuit to support transceiving of the power saving signal, so that the design complexity of a transceiving end is reduced.

In the embodiment of the application, the network device may notify the terminal device through DCI or RRC signaling that the reference signal is used for WUS or GTS; in the following embodiments, only the network device informs the terminal device through DCI that the reference signal is used for WUS or GTS will be described as an example.

In the embodiment of the application, the network device designs the power saving signal by referring to the signal, and may adopt a WUS mechanism or a GTS mechanism. For example, the network device employs a WUS mechanism, and when the network device determines to schedule the terminal device within a DRX cycle, the network device determines the WUS; then the network equipment sends a reference signal to the terminal equipment, wherein the reference signal is used for indicating the WUS; the terminal device can monitor the PDCCH within the DRX period according to the WUS; the network equipment adopts a GTS mechanism, and when the network equipment determines that the terminal equipment is not scheduled in the DRX period, the network equipment determines the GTS; then the network device sends a reference signal to the terminal device, the reference signal is used for indicating the GTS, and the terminal device may not monitor the PDCCH in the DRX cycle according to the GTS; the following describes, by using specific embodiments, that the network device uses the above two mechanisms to send a reference signal to the terminal device to inform the terminal device to monitor the PDCCH or not to monitor the PDCCH in the DRX cycle. In the following embodiments, the network device takes a base station and a terminal device take UE as an example for description.

Referring to fig. 2, fig. 2 shows a base station transmitting a reference signal to a UE, wherein the reference signal indicates a WUS; the UE then monitors the PDCCH for a DRX cycle according to the WUS. One embodiment of a signal processing method in an embodiment of the present application includes:

201. the base station determines to schedule the UE within the DRX cycle.

In the process of communication of the UE, the UE reports a measurement report to the base station, the base station side may determine a current signal state and allocable resources according to the measurement report, and the base station may allocate corresponding resources to the UE according to a current service condition of the UE, generate resource scheduling information, and send the resource scheduling information to the UE. The base station side can judge whether to schedule the UE in the DRX period according to the current service condition of the UE, if so, the base station can determine that the UE needs to monitor the PDCCH in the DRX period so as to obtain the resource allocated by the base station to the UE.

It should be noted that the base station determines to schedule the UE in a DRX cycle, where the DRX cycle may be at least one DRX cycle, for example, the base station determines to schedule the UE in M cycles, where M is a positive integer, and M may be preconfigured by the base station, and as long as the UE side receives a corresponding WUS sent by the base station side, the UE may determine to monitor the PDCCH in M DRX cycles; optionally, M may also be carried in a WUS sent by the base station to the UE, and is used to inform the UE to monitor the PDCCH in M DRX cycles, where M is a positive integer, and is not limited herein.

It should be noted that, if the base station determines that the UE is not scheduled in the DRX cycle according to the service condition of the UE, the base station does not send the reference signal to the terminal device, and at this time, the terminal device does not receive the reference signal sent by the base station, and the terminal device does not monitor the PDCCH in the DRX cycle. In addition, in the 5G communication system, if the starting time point of the beam measurement performed by the UE is before the starting time point of the DRX cycle, if the base station determines that the UE is not scheduled in the DRX cycle, and a first duration for which the UE does not perform the beam measurement is less than a preset duration, the UE may not perform the beam measurement in a second duration, a sum of the first duration and the second duration is less than or equal to the preset duration, the second duration is not greater than a duration corresponding to the DRX cycle, and the duration corresponding to the DRX cycle is a duration corresponding to the DRX cycle for which the network device determines that the UE is not scheduled.

Taking fig. 3 for explanation, fig. 3 is an example in which the base station determines that the UE is not scheduled in the next DRX cycle, if the starting time point of beam measurement performed by the UE is before the On-Duration of the DRX cycle, that is, before the starting time point of the next DRX cycle, and the UE does not receive the reference signal transmitted by the base station, assuming that the UE does not perform beam measurement for 4 consecutive DRX cycles before the current time, that is, the first Duration for which the UE does not perform beam measurement continuously is 4 DRX cycles, and the preset threshold is the Duration of 5 DRX cycles, it is known that the first Duration for which the UE does not perform beam measurement continuously is smaller than the preset threshold, and the UE does not perform beam measurement for the next DRX cycle.

For another example, assuming that the preset Duration is a Duration of 5 DRX cycles, if the base station determines that the UE is not scheduled in the following 4 DRX cycles of the UE, the UE will not receive a reference signal sent by the base station, and if the starting time point of the beam measurement of the UE is before the On-Duration of the DRX cycle and the Duration for which the UE does not perform the beam measurement continuously before the current time is a Duration of 3 DRX cycles, the UE may not perform the beam measurement in the first two DRX cycles of the 4 DRX cycles and needs to turn On the beam management in the third DRX cycle of the 4 DRX cycles.

Therefore, in this implementation, in the multi-beam system, when the starting point of the UE performing the beam measurement is started before the DRX cycle, and the UE does not receive the WUS sent by the base station, it may be determined that the channel does not need to be monitored in the subsequent DRX cycle, and then the duration of not performing the beam measurement may be determined according to the duration of the UE that does not currently perform the beam measurement continuously, so as to optimize the beam management for monitoring the PDCCH, and further save the power consumption of the UE.

202. The base station determines the WUS.

The base station determines to schedule the UE in the DRX cycle, so the UE needs to be woken up before the DRX cycle and monitor the channel in the DRX cycle, so that the UE can acquire the scheduling resource allocated to it by the base station.

203. The base station transmits the DCI to the UE.

In the present application, the power saving signal is designed by a reference signal, and in order to distinguish from other reference signals in the prior art, the base station may transmit DCI to the UE, which is used to inform the UE that the reference signal is used for WUS. For example, the base station may inform the UE through DCI that the reference signal received by the UE on the corresponding time-frequency resource is used for WUS.

204. The UE determines the reference signal for WUS from the DCI.

After the UE receives the DCI transmitted by the base station, the UE may determine the reference signal for the WUS according to the DCI.

In this embodiment, there is no fixed execution sequence between steps 203 to 204 and steps 201 to 202, step 201 to 202 may be executed first, and then step 203 to step 204 may be executed, or step 203 to step 204 may be executed first, and then step 201 to step 202 may be executed, or step 201 to step 202 and step 203 to step 204 may be executed simultaneously according to the situation, and the specific details are not limited herein.

205. The base station sends the target location for receiving the reference signal to the UE.

In the present application, the power saving signal is designed by a reference signal for indicating the WUS, and in the present embodiment, the WUS of different UEs are distinguished by different reception positions, and therefore, the base station can transmit to the UE a target position where the UE receives the reference signal, the target position being used to indicate the reception position where the UE receives the WUS. The subsequent UE may receive the reference signal transmitted by the base station at the target location.

The WUS of different UEs are distinguished by different receiving locations, and in a specific implementation process, the WUS of different UEs may be distinguished by a time domain, a frequency domain, or a code domain, for example, the WUS of different UEs may be distinguished by a time-frequency resource used by a network device to send a corresponding WUS, or the WUS of different UEs may be distinguished by a reference signal carrying a corresponding scrambling code, which is not limited in the specific application. One possible implementation is that if the base station uses the time domain or the code domain to distinguish the WUS of different UEs, the base station transmits the corresponding WUS to the UE on all frequency bands; if the base station uses the frequency domain to distinguish the WUs of different UEs, the base station transmits the WUs in the frequency band supported by the UE.

In this embodiment, there is no fixed execution sequence between step 205 and steps 201 to 202, and step 205 may be executed first, and then step 201 to step 202 are executed, or step 201 to step 202 are executed first, and then step 205 is executed, or step 201 to step 202 and step 203 are executed simultaneously according to the situation, which is not limited herein.

In this embodiment, when the UEs are not grouped, the base station may set a receiving location for each UE to receive the WUS, and send the receiving location to the UE; optionally, the base station may also divide the UEs into a plurality of groups, and then set a receiving position for receiving the corresponding WUS for each group of UEs, and the base station may send the receiving position for receiving the corresponding WUS for each group of UEs to each group of UEs, which is not limited herein.

The following describes in detail a procedure in which the base station transmits a reception location to the UE for receiving the reference signal for two different schemes, UE non-grouping and UE grouping.

In the case that the UE does not perform grouping, before the UE receives the reference signal transmitted by the base station at the target location, the UE may receive a reception location at which the UE receives the WUS through signaling transmitted by the base station, specifically, the reception location at which the UE receives the WUS corresponding to the reception of the UE, which is notified by the base station through the first signaling.

It should be noted that the first signaling may be RRC signaling or may be other types of signaling, and is not limited herein specifically, and the base station may also notify the UE of the receiving location of the corresponding WUS through DCI.

For the case of UE grouping, the UE may determine the receiving location where it receives the corresponding WUS through signaling and system information sent by the base station, or may determine the receiving location where it receives the corresponding WUS through system information sent by the base station, which is described in detail below with reference to fig. 4 and 5:

first, referring to fig. 4, fig. 4 shows that the base station informs the UE of the receiving location of the corresponding WUS through the second signaling and the first system information, and the specific process includes:

401. and the base station sends a second signaling to the UE, wherein the second signaling carries the group number information of the UE.

The base station divides the UE into a plurality of groups according to a preset grouping rule, and each group is allocated with a corresponding group number. The base station may send a second signaling to the UE, where the second signaling carries group number information of the UE.

It should be noted that the second signaling may be RRC signaling, or may be other types of existing signaling, and is not limited herein.

402. And the UE determines the group number to which the UE belongs according to the group number information.

The UE acquires the group number information, and can determine the group number to which the UE belongs.

403. And the base station sends first system information to the UE, wherein the first system information carries the receiving position of each group of UE for receiving the corresponding WUS.

The base station may send first system information to the UEs, where the first system information carries receiving positions where the UEs in each group receive corresponding WUSs. It should be noted that the first system information may be transmitted by the base station to each group of UEs in a broadcast manner, or may be transmitted in other transmission manners, and is not limited herein.

404. And the UE determines the receiving position of the UE for receiving the WUS according to the group number of the UE and the receiving position of each group of the UE for receiving the corresponding WUS.

The UE receives the corresponding receiving position of the WUS and the group number of the corresponding group according to each group of UE in the first system information transmitted by the base station, and can determine the receiving position of the corresponding WUS.

Referring to fig. 5, in fig. 5, the base station informs the UE of the receiving location of the corresponding WUS through the second system information, and the specific process includes:

501. and the base station sends the second system information to the UE.

The base station may divide the UEs connected to the communication system into a plurality of groups according to a grouping rule, and each group may be assigned a corresponding group number. The base station then transmits second system information to the UEs, wherein the second system information includes grouping rules and reception positions at which the respective groups of UEs receive the corresponding WUS.

The grouping rule may be a mapping relationship between a group number of each group of UEs and a DRX cycle value, or may be a grouping number and a calculation formula of the UEs, which is not limited herein. The following is presented for these two grouping rules:

a. the grouping rule is the mapping relation between the group number of each group of UE and the DRX period value;

when the base station side groups the UEs of the communication system, the base station may group the UEs with the same DRX cycle value into one group, that is, the group numbers of the UEs with the same DRX cycle value are the same; for example: assuming that the DRX cycle value range of the current UE to be grouped is {2,4,8,16,3,6,12,24} ms, the base station may group the current UE to be grouped into eight groups, and the base station assigns a corresponding group number to each group, for example, a corresponding one specific group number with a DRX cycle value of 2ms and another specific group number with a DRX cycle value of 4 ms.

The base station can also divide the UE with the DRX period value meeting the integral multiple relation into one group, namely the group numbers of the UE with the DRX period value meeting the integral multiple relation are the same; for example, assuming that the current DRX cycle value range of the UE is {2,4,8,16,3,6,12,24} ms, the DRX cycle values of {2,4,8,16 } ms all conform to an integer multiple relationship, and the DRX cycle values of {3,6,12,24} ms also conform to an integer multiple relationship, so the base station can group the DRX cycle values of {2,4,8,16 }; dividing {3,6,12,24} into another group, and allocating corresponding group numbers to the two groups of UEs;

optionally, the base station may further group UEs that satisfy the integer multiple relationship in the DRX cycle values and satisfy a target condition, where the target condition is that the DRX cycle values are sequentially taken from a minimum DRX cycle, and the number of the DRX cycle values is N, where N is a positive integer, that is, the group numbers of the UEs that satisfy the integer multiple relationship in the DRX cycle values are the same. The following are given by way of example:

assuming that the DRX cycle values of the current UE are {2,4,8,16,3,6,12,24} ms, respectively, the DRX cycle values are required to satisfy a 2-fold relationship, and N is 2. The base station can take values of DRX period values, and the minimum DRX period value is 2ms from the current DRX period value of the UE, so that the base station starts taking values from 2ms and takes values in sequence, so that the base station can divide DRX periods of {2,4} ms into a group, the two DRX period values are in a double relation, and the number of the DRX period values is two, so that the target condition is met; then, the base station continues to take values from the minimum DRX period value of 3ms, the DRX periods can be divided into a group of {3,6} ms, and the condition is met in the same way; in the same way, the base station continues to carry out DRX period value, and a group of DRX period values of {8,16} ms can be obtained; the DRX cycle value is set to 12,24 ms. I.e. the current UE is divided into four groups and each group is assigned a corresponding group number.

For another example, assuming that the DRX cycle values of the current UE are {2,4,8,16,32, 64, 3,6,12,24, 48, 96} ms, respectively, the DRX cycle values are required to satisfy a 2-fold relationship, and N is 3. The base station performs DRX period value taking, wherein the current minimum DRX period value is 2ms, and the base station is assumed to take values in a double relation and take values in sequence, so that the base station can divide UE with DRX periods of {2,4, 8} ms into a group, the three DRX period values are in a double relation, and the number of the DRX period values is three, so that the target condition is met; then, the base station continues to take values from the minimum DRX period of 3ms, and the UEs with DRX periods of {3,6,12 } ms can be divided into a group, and the conditions are met in the same way; in the same way, the base station continues to take the value of the DRX period, so that the UE with the DRX period value of {16, 32, 64} ms is divided into one group, and the UE with the DRX period value of {24, 48, 96} ms is divided into one group; i.e. the current UE is divided into four groups and each group is assigned a corresponding group number.

b. The grouping rule is a grouping number and a calculation formula, the base station determines to divide the UE in the system into different groups, the grouping number is determined by the base station, the grouping rule comprises the grouping number and the calculation formula, and then the UE can calculate and determine the group number to which the UE belongs according to the calculation formula. The calculation formula can be a complementation formula mod, and assuming that the number of packets is 5 and the ID of the UE is 10, it can be known that the number of packets of the UE ID mod, that is, 10mod 5 is equal to 0, that is, the group number to which the UE belongs is 0; for another example, assuming that the number of packets is 4 and the UE ID is 7, it can be known that 7mod 4 is equal to 3, i.e., the group number to which the UE belongs is 3.

502. And the UE determines the group number to which the UE belongs according to the grouping rule.

The UE can determine the group number to which it belongs according to the grouping rule. The following describes the procedure of the UE determining the group number to which the UE belongs with respect to the two types of grouping rules a and b described in step 501; if the grouping rule is a mapping relationship between the group number of each group of UEs and the DRX cycle value, assuming that the mapping relationship includes a group number 1 corresponding to a DRX cycle of 3ms, the UE may determine that its group number is 1 if the DRX cycle value of the UE is 3 ms; if the grouping rule is the grouping number and the calculation formula, the UE calculates the group number to which the UE belongs according to the grouping number and the calculation formula.

503. And the UE determines the receiving position of the corresponding WUS according to the group number to which the UE belongs and the receiving position of the corresponding WUS received by each group of UE.

Since the receiving position where each group of UEs receives the corresponding WUS includes the mapping relationship between the group number of each group of UEs and the receiving position of the corresponding WUS, after the UE determines the group number to which it belongs, it can determine the receiving position where it receives the corresponding WUS according to the group number and the receiving position where each group of UEs receives the corresponding WUS.

206. The base station transmits a reference signal to the UE, the reference signal indicating the WUS.

After the base station determines the WUS, a reference signal may be transmitted to the UE, where the reference signal indicates the WUS, and then the UE may receive the reference signal at the target location. Please refer to fig. 3, fig. 3 is a schematic diagram illustrating a relationship between a WUS and a DRX cycle transmitted by a base station received by a UE side, and taking an example that the base station determines to schedule the UE in a next DRX cycle, the UE receives the reference signal based On a target location at a time point before a Duration On-Duration of the next DRX cycle and a time difference from a starting time point of the next DRX cycle is GAP.

207. The UE monitors the PDCCH according to the WUS in a DRX period.

After receiving the reference signal, the UE may monitor the PDCCH according to the WUS for a DRX cycle, which may be M cycles. Wherein, M can be configured for the UE in advance for the base station, and as long as the UE receives the corresponding WUS sent by the base station, the UE monitors the PDCCH in the following M DRX cycles; optionally, the base station may also carry instructions in the sent WUS to the UE to monitor the PDCCH in M DRX cycles, so the UE may monitor the PDCCH in M DRX cycles subsequently according to the WUS, where M is a positive integer.

In the embodiment of the application, a network device determines a WUS, and the WUS is used for indicating a terminal device to monitor a PDCCH in a DRX period; the network equipment informs the terminal equipment of a target position for receiving a reference signal, wherein the target position is used for indicating a receiving position of the terminal equipment for receiving the WUS; the network device then transmits the reference signal to the terminal device, the reference signal indicating the WUS. That is, in the technical solution of the present application, the network device sends an existing reference signal to the terminal device, and the reference signal is used for indicating the WUS, and the existing reference signal is used for indicating the WUS to inform the terminal device to monitor the PDCCH in the DRX cycle. Therefore, the power saving signal of the terminal device is carried by the reference signal in the prior art, and the network device and the terminal device do not need to redesign the dedicated transceiving mechanism of the power saving signal, such as: the network equipment side and the terminal equipment side do not need to design a special transceiving circuit to support transceiving of the power saving signal, so that the design complexity of a transceiving end is reduced.

Referring to fig. 6, fig. 6 shows a base station transmitting a reference signal to a UE, where the reference signal is used to indicate a GTS; the UE then determines not to monitor the PDCCH for the DRX cycle according to the GTS. One embodiment of a signal processing method in an embodiment of the present application includes:

601. the base station determines that the UE is not scheduled for the DRX cycle.

In the process of communication of the UE, the UE reports a measurement report to the base station, the base station side may determine a current signal state and allocable resources according to the measurement report, and the base station may allocate corresponding resources to the UE according to a current service condition of the UE, generate resource scheduling information, and send the resource scheduling information to the UE. Therefore, the base station side can judge whether to schedule the UE in the DRX period according to the current service condition of the UE, and if not, the base station can determine that the UE does not need to monitor the PDCCH in the DRX period.

It should be noted that the base station determines not to schedule the UE in a DRX cycle, where the DRX cycle may be at least one DRX cycle. For example, the base station determines that the UE is not scheduled in M cycles, where M is a positive integer, M may be preconfigured by the base station, and the UE may determine not to monitor the PDCCH in M DRX cycles as long as receiving a corresponding GTS sent by the base station on the UE side; optionally, M may also be carried in a GTS generated by the base station for the UE, and is used to inform the UE not to monitor the PDCCH in M DRX cycles, where M is a positive integer, and is not limited herein.

It should be noted that, if the base station determines to schedule the UE in the DRX cycle according to the service condition of the UE, the base station does not send the reference signal to the UE, where the reference signal is used to indicate GTS, and at this time, the UE does not receive the reference signal sent by the base station, and then monitors the PDCCH in the DRX cycle.

602. The base station determines the GTS.

The base station determines that the UE is not scheduled during the DRX cycle, then the base station may determine a GTS that indicates that the UE does not monitor the PDCCH during the DRX cycle.

603. The base station transmits the DCI to the UE.

In the present application, the power saving signal is designed by a reference signal, and in order to distinguish from a reference signal that is common in the prior art, the base station may transmit DCI to the UE, the DCI being used to inform the UE that the reference signal is used for GTS. For example, the base station may inform the UE through DCI that the reference signal received by the UE on the corresponding time-frequency resource is used for GTS.

604. The UE determines the reference signal for GTS according to the DCI.

After receiving the DCI transmitted by the base station, the UE may determine that the reference signal is used for GTS according to the DCI.

In this embodiment, there is no fixed execution sequence between steps 603 to 604 and steps 601 to 602, step 601 to 602 may be executed first, and then step 603 to 604 may be executed, or step 603 to 604 may be executed first, and then step 601 to 602 may be executed, or step 601 to step 602 and step 603 to step 604 may be executed simultaneously according to the situation, and the specific details are not limited herein.

605. The base station transmits a target position for receiving the reference signal to the UE.

In the present application, the power saving signal is designed by a reference signal, which is used to indicate the GTS, in the present embodiment, GTSs of different UEs are distinguished by different receiving locations, so that a base station may send a target location for the UE to receive the reference signal to the UE, where the target location is used to indicate a receiving location for the UE to receive the GTS. The subsequent UE may receive the reference signal transmitted by the base station at the target location.

In a specific implementation process, the GTSs of different UEs may be distinguished by different receiving locations, and may be distinguished by a time domain, a frequency domain, or a code domain, for example, the GTSs of different UEs may be distinguished by a time-frequency resource used by a network device to send a corresponding GTS, or the GTSs of different UEs may be distinguished by a reference signal carrying a corresponding scrambling code, which is not limited in the specific application. One possible implementation is that, if the base station uses the time domain or the code domain to distinguish the GTSs of different UEs, the base station sends the GTSs on all frequency bands when sending the corresponding GTSs to the UE; if the base station uses the frequency domain to distinguish the GTS of different UEs, the base station transmits the GTS in the frequency band supported by the UE.

In this embodiment, there is no fixed execution sequence between step 605 and steps 601 to 602, and step 605 may be executed first and then steps 601 to 602, or step 601 to step 602 and then step 605 may be executed first, or step 601 to step 602 and step 603 may be executed simultaneously according to the situation, which is not limited herein.

In this embodiment, when the UE does not group, the base station may set a receiving position for receiving the GTS for each UE, and send the receiving position to the UE; optionally, the base station may also divide the UEs into a plurality of groups, and then set a receiving position for receiving the corresponding GTS for each group of UEs, and the base station may send the receiving position for receiving the corresponding GTS for each group of UEs to each group of UEs, which is not limited herein.

The following describes in detail a procedure in which the base station transmits a reception location for receiving the reference signal to the UE for two different schemes, UE grouping and UE non-grouping.

First, for a case that the UE does not perform grouping, before the UE receives the reference signal sent by the base station at the target location, the UE may receive a receiving location of the GTS corresponding to the UE through a signaling sent by the base station, specifically, the receiving location of the GTS corresponding to the UE, which is notified by the base station through the third signaling, is received by the UE.

It should be noted that the third signaling may be RRC signaling, or may be other types of signaling, and the specific details are not limited herein, and the base station may also notify the UE of the receiving location of the corresponding GTS through DCI.

For the case of UE grouping, the UE may determine the receiving location of its GTS through signaling and system information sent by the base station, or may determine the receiving location of its GTS through system information sent by the base station, which is described in detail below with reference to fig. 7 and 8:

referring to fig. 7, fig. 7 shows that the base station informs the UE of the receiving location of the GTS corresponding to the UE through the fourth signaling and the third system information, and the specific process includes:

701. the base station sends fourth signaling to the UE.

702. And the UE determines the group number to which the UE belongs according to the group number information.

Steps 701 to 702 are similar to steps 401 to 402 in fig. 4, and detailed description thereof is omitted here.

703. And the base station sends third system information to the UE, wherein the third system information carries the receiving position of each group of UE for receiving the corresponding GTS.

The base station may send third system information to the UEs, where the third system information carries the receiving positions where the respective groups of UEs receive the corresponding GTS. It should be noted that the third system information may be transmitted by the base station to each group of UEs in a broadcast manner, or may be transmitted in other transmission manners, and is not limited herein.

704. And the UE determines the receiving position of the GTS according to the group number to which the UE belongs and the receiving position of the GTS corresponding to the group of the UE.

The UE may determine the receiving position of the GTS corresponding to the UE according to the receiving position of the GTS corresponding to each group of UEs in the third system information sent by the base station and the group number to which the UE belongs.

Referring to fig. 8, in fig. 8, the base station informs the UE of the receiving location of the GTS corresponding to the UE through the fourth system information, and the specific process includes:

801. and the base station sends the fourth system information to the UE.

The base station may divide the UEs connected to the communication system into a plurality of groups according to a grouping rule, and each group may be assigned a corresponding group number. And then the base station sends fourth system information to the UE, wherein the fourth system information comprises grouping rules and receiving positions of the corresponding GTSs received by the groups of UEs.

The grouping rule may be a mapping relationship between a group number of each group of UEs and a DRX cycle value, or may be a grouping number and a calculation formula of the UEs, which is not limited herein. For specific descriptions of the two grouping rules, reference is made to the specific description of the grouping rule corresponding to step 501 in fig. 5, and details thereof are not repeated here.

802. And the UE determines the group number to which the UE belongs according to the grouping rule.

Step 802 is similar to step 502 in fig. 5, and detailed description thereof is omitted here.

803. And the UE determines the receiving position of the corresponding GTS according to the group number to which the UE belongs and the receiving position of the GTS to which the UE receives the corresponding GTS.

Since the receiving position of the GTS corresponding to each group of UEs includes the mapping relationship between the group number of each group of UEs and the receiving position of the GTS corresponding to each group of UEs, after the UE determines the group number to which the UE belongs, the UE can determine the receiving position of the GTS corresponding to the UE according to the group number and the receiving position of the GTS corresponding to each group of UEs.

606. The base station transmits a reference signal indicating the GTS to the UE.

After the base station determines the GTS, a reference signal may be transmitted to the UE, where the reference signal indicates the GTS, and the UE may receive the reference signal at the target location. Please refer to fig. 9, fig. 9 is a diagram illustrating a relationship between a GTS and a DRX cycle that a UE receives from a base station, and the reference signal is received based On a target location at a time point before the Duration On-Duration of the next DRX cycle and at a time point when a time difference from a start time point of the next DRX cycle is GAP, for example, the base station determines that the UE does not schedule the UE in the next DRX cycle.

607. And the UE does not monitor the PDCCH according to the GTS in the DRX period.

After receiving the reference signal, the UE may not monitor the PDCCH for a DRX cycle according to the GTS, where the DRX cycle may be M cycles. Wherein, M may be configured for the UE in advance for the base station, and as long as the UE receives the corresponding GTS sent by the base station, the UE does not monitor the PDCCH in the following M DRX cycles; optionally, the base station may also indicate, in the GTS, that the UE does not monitor the PDCCH in M DRX cycles, and then the UE may not monitor the PDCCH in the following M DRX cycles according to the GTS, where M is a positive integer.

In addition, in the 5G communication system, if the starting time point of the beam measurement performed by the UE is before the starting time point of the DRX cycle, if the base station determines not to schedule the UE in the DRX cycle, the UE receives a reference signal sent by the base station, the reference signal being used for indicating a WUS, and a first duration for which the UE does not perform the beam measurement is less than a preset duration, the UE may not perform the beam measurement for a second duration, wherein a sum of the first duration and the second duration is less than or equal to the preset duration, and the second duration is not greater than a duration corresponding to the DRX cycle. The following examples illustrate:

referring to fig. 9, fig. 9 is a diagram illustrating an example that a base station determines that a UE does not schedule the UE in a next DRX cycle, where if a start time point of beam measurement performed by the UE is before an On-Duration of the DRX cycle, that is, before the start time point of the next DRX cycle, the UE receives a reference signal sent by the base station, where the reference signal is used to indicate a GTS, and if a first Duration that the UE does not perform beam measurement before a current time is 4 DRX cycles and a preset threshold is a Duration of 5 DRX cycles, it is known that the first Duration that the UE does not perform beam measurement is smaller than the preset threshold, and the UE does not perform beam measurement for the next DRX cycle.

For another example, assuming that the preset Duration is a Duration of 5 DRX cycles, the base station determines that the UE is not scheduled in the subsequent 4 DRX cycles of the UE, and then the UE receives a reference signal sent by the base station, and if the starting time point of beam measurement performed by the UE is before the On-Duration of the DRX cycle and the Duration for which beam measurement is not performed by the UE before the current time is a Duration of 3 DRX cycles, the UE may not perform beam measurement in the first two DRX cycles of the 4 DRX cycles, and turn On beam management in the third DRX cycle of the 4 DRX cycles. Therefore, in this embodiment, in the multi-beam system, when the starting point of the UE performing the beam measurement is started before the DRX cycle, and the UE receives the GTS transmitted by the base station, it may be determined that the channel does not need to be monitored in the subsequent DRX cycle, and then the duration of not performing the beam measurement may be determined according to the duration of the UE that does not currently perform the beam measurement continuously, so as to optimize beam management for monitoring the PDCCH, and further save power consumption of the UE.

In the embodiment of the application, the network equipment determines a GTS, and the GTS is used for indicating the terminal equipment to monitor the PDCCH in the DRX period; the network device informs the terminal device of a target position for receiving the reference signal, wherein the target position is used for indicating the receiving position of the terminal device for receiving the GTS; the network device then transmits the reference signal to the terminal device, where the reference signal is used to indicate the GTS. That is, in the technical solution of the present application, an existing reference signal is sent to a terminal device by a network device, and the reference signal is used to indicate a GTS, and the existing reference signal is used to indicate the GTS to inform the terminal device not to monitor a PDCCH in a DRX cycle. Therefore, the power saving signal of the terminal device is carried by the reference signal in the prior art, and the network device and the terminal device do not need to redesign the dedicated transceiving mechanism of the power saving signal, such as: the network equipment side and the terminal equipment side do not need to design a special transceiving circuit to support transceiving of the power saving signal, so that the design complexity of a transceiving end is reduced.
