Description

Information processing method and information processing device

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method and an information processing apparatus.

Background

In Long Term Evolution (LTE), when a terminal and a network side do not establish a connection, the terminal monitors a paging message on a specific time-frequency resource, and the specific time-frequency resource for detecting the paging message is called Paging Occasion (PO). When a terminal monitors Downlink Control Information (DCI) scrambled by a paging radio network temporary identifier (P-RNTI) on a PO, the terminal receives the paging message on a time-frequency resource indicated by the DCI, and the terminal knows whether the terminal is paged by a base station or not through the paging message.

In order to reduce power consumption of a terminal and save electric energy, a Wake Up Signal (WUS) mechanism is introduced in LTE, and the WUS mechanism is used for clearly informing the terminal of the existence of P-RNTIDCI on PO before the P-RNTI DCI is detected on the PO by the terminal so as to avoid detection on the PO without the P-RNTI DCI.

One PO in LTE is a subframe, and different terminals monitor P-RNTI DCI on their respective PO. In a new radio access Network (NR), beams are used between a base station and a terminal for signal transmission, one beam corresponds to one slot, one PO corresponds to a group of beams, and different terminals receive P-RNTI DCI on different beams.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, some concepts related to the embodiments of the present application are first described below: the terminal, beam, paging and wake-up signal WUS are briefly introduced.

A terminal, also referred to herein as a terminal device, may refer to a device that provides voice and/or data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. Terminal devices, which may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, hand-held, computer-included, or vehicle-mounted mobile devices, may communicate with one or more core networks via a Radio Access Network (RAN), which may exchange language and/or data with the RAN. Such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless terminal may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal (remote terminal), an access terminal (access terminal), a user terminal (user terminal), a user agent (user agent), or a User Equipment (UE).

In various embodiments of the present application, a beam (beam) may be understood as a spatial resource, and may refer to a transmission or reception precoding vector having energy transmission directivity. The sending or receiving precoding vector can be identified by index information, where the index information may correspond to a resource Identifier (ID) of a configured terminal, for example, the index information may correspond to an identifier of a configured Synchronization Signal Block (SSB), or an identifier or a resource of a channel state information-reference signal (CSI-RS); or may be a flag or a resource of a correspondingly configured uplink Sounding Reference Signal (SRS). Optionally, the index information may also be index information explicitly or implicitly carried by a signal or channel carried by a beam. The energy transmission directivity may refer to precoding a signal to be transmitted by using the precoding vector, the signal subjected to precoding has a certain spatial directivity, and the received signal subjected to precoding by using the precoding vector has a good receiving power, such as meeting a receiving demodulation signal-to-noise ratio; the energy transmission directivity may also mean that the same signal transmitted from different spatial locations received through the precoding vector has different reception powers. Optionally, the same communication device (e.g. terminal device or network device) may have different precoding vectors, and different devices may also have different precoding vectors, i.e. corresponding to different beams. One communication device may use one or more of a plurality of different precoding vectors at the same time, i.e. may form one beam or a plurality of beams at the same time, depending on the configuration or capabilities of the communication device.

In the NR system, the frequency of the signal is higher, the attenuation of the high frequency signal is more obvious than that of the low frequency signal, and the energy loss during the signal transmission is larger. Generally speaking, a signal with a frequency of 6GHz is taken as a criterion for determining high and low frequency signals, a signal with a frequency of less than 6GHz is taken as a low frequency signal, and a signal with a frequency of more than or equal to 6GHz is taken as a high frequency signal. In the NR system, in order to solve the problems of reduced signal coverage and weakened signal strength caused by signal attenuation, a base station may transmit different beams in different directions in space to improve the spatial coverage of signals and enhance the signal strength. Similarly, the terminal performs beam scanning (beam scanning) on the beams in the space to receive the downlink information transmitted by the base station.

In order to facilitate understanding of the beam scanning in the embodiments of the present application, the beam scanning is described in detail below with reference to fig. 1.

Fig. 1 is a schematic diagram of an embodiment of a group of beam scans provided in an embodiment of the present application. As shown in fig. 1, the base station sequentially transmits different beams in time sequence in different spatial directions, and the transmission process of such beams is similar to scanning, and is called beam scanning. It will be readily appreciated that in space the signal spreads out like a cone into the surrounding space, the oval shape shown in figure 1 being essentially a cone, and the oval shape shown in figure 1 being for convenience of illustration only. Two beams in adjacent directions in a group of beams in space may be intersected or not intersected, and the application is not limited in any way.

Paging (Paging) refers to that a network device such as a base station searches for a terminal, for example, when the network device needs to send downlink information, the network device sends Paging information to the terminal, where the Paging information carries an identifier of the terminal. If the terminal detects that the identifier of the terminal is in the Paging information, the terminal sends a request to the network equipment to access the network. A terminal in an idle (idle) state monitors Downlink Control Information (DCI) on a specific time-frequency resource, and if the terminal monitors that Paging information is issued, the terminal receives the Paging information according to an indication in the DCI. The specific time domain resource used by the DCI corresponding to the monitored Paging information is referred to as a Paging Occasion (PO), the Paging occasion is also referred to as a Paging time, and a time for detecting the DCI on the PO is generally referred to as a Physical Downlink Control Channel (PDCCH) detection time. In LTE, one PO includes one subframe, and for one terminal, one PO includes only one PDCCH detection time of the terminal. In the NR, the unit of PDCCH detection time is a slot (slot), a PO includes a beam surfing, that is, a group of SSBs, and one SSB corresponds to one PDCCH detection time, so that one PO in the NR includes at least one PDCCH detection time. It can also be understood that a PO includes a set of beams, and one beam corresponds to one PDCCH detection time, and the understanding of the PO is not limited in this patent. It should be noted that the DCI corresponding to the Paging information is generally downlink control information scrambled by the radio network temporary identity P-RNTI. The P-RNTI scrambled DCI may carry part of the information in the paging information, for example, the P-RNTI scrambled DCI may carry indication information indicating whether the system information is changed and/or indication information indicating an emergency, so that the paging information may not indicate whether the system information is changed or whether an emergency exists.

The above-mentioned paging occasion is described in detail with reference to fig. 2, and fig. 2 is a schematic diagram of a paging occasion PO according to an embodiment of the present application.

As shown in fig. 2, the paging occasions in the discontinuous period are shown in fig. 2, the paging occasions are shown as gray parts in fig. 2, further, fig. 2 also shows that one paging occasion is composed of 8 slots (slots), each slot corresponds to a beam shown as a black oval part in fig. 2, a first beam is transmitted in a north direction of the base station on a first slot, a second beam is transmitted in a 45 ° east direction of the base station on a second slot, a third beam is transmitted in a east direction of the base station on a third slot, a fourth beam is transmitted in a 45 ° south east direction of the base station on a fourth slot, a fifth beam is transmitted in a south direction of the base station on a fifth slot, a sixth beam is transmitted in a 45 ° south direction of the base station on a sixth slot, and a seventh beam is transmitted in a seventh slot, the eighth beam is transmitted to the 45 ° northwest direction of the base station on the eighth slot, so as to implement signal coverage on the whole space.

The wakeup signal (WUS) is indication information for indicating whether the end network device will transmit DCI corresponding to the Paging information on the PO. The terminal can know whether the network equipment can send the DCI corresponding to the Paging information on the PO by detecting the WUS. If so, the terminal performs DCI detection on the corresponding PO, otherwise, the terminal does not perform detection, so as to avoid unnecessary power consumption and save electric quantity. It should be noted that the WUS may be used to wake up the terminal under appropriate conditions, and the WUS may also be used to control the terminal to be in a sleep state under appropriate conditions.

An information processing system is provided in the embodiment of the present application, and fig. 3(a) is a system block diagram of the information processing system provided in the embodiment of the present application.

As shown in fig. 3(a), the method includes: a first information processing apparatus and a second information processing apparatus.

Wherein the first information processing apparatus is mainly configured to: performing a beam scan for a first time period, the first time period being a time period for scanning a first set of beams, the first set of beams including at least one beam; and determining whether indication information is received on a first group of beams according to the beam scanning result so as to determine whether the terminal needs to detect the downlink control information, wherein the first group of beams has a function of bearing the indication information, and the indication information is used for indicating whether the terminal needs to detect the downlink control information.

The second information processing apparatus is mainly used for: generating indication information, wherein the indication information is used for indicating whether the terminal detects downlink control information or not; and sending a first group of beams, wherein the first group of beams have the function of carrying the indication information, the time period for scanning the first group of beams is a first time period, and the first group of beams comprises at least one beam.

The information processing system shown in fig. 3(a) is suitable for an LTE/5GC system architecture supporting communication of both the fourth generation mobile communication system 4G and the fifth generation mobile communication system 5G, and also suitable for a 5G (NR) system architecture supporting 5G communication, and even suitable for a system architecture corresponding to a future mobile communication system, especially suitable for a base station paging scenario of NR. The first information processing apparatus includes, but is not limited to, a terminal or a component in a terminal, and the second information processing apparatus includes, but is not limited to, a base station or a component in a base station.

In order to facilitate understanding of the information processing method provided in the embodiment of the present application, the following takes a base station and a terminal as an example to describe in detail the information processing method in the embodiment of the present application, specifically as follows:

fig. 3(b) is a schematic diagram of an embodiment of an information processing method provided in an embodiment of the present application.

As shown in fig. 3(b), the method includes:

301. the base station generates indication information, and the indication information is used for indicating whether the terminal detects the downlink control information.

The downlink control information may be DCI, or other types of downlink control information.

Optionally, the indication information may be a wake-up signal WUS, where the WUS may include a sequence, such as a ZC (zadoff-chu) sequence, a signal, a pilot frequency, or a signaling, and only needs to have a function of indicating whether the terminal detects DCI delivery, which may be regarded as the indication information described in this application.

Specifically, the WUS is a ZC sequence, and when the ZC sequence is detected, it indicates that the base station is about to issue DCI, and the terminal needs to detect the DCI; when the ZC sequence is not detected, it indicates that the terminal does not need to detect the DCI. Or the WUS corresponds to a bit, and when the bit is 1, the terminal is indicated to detect the DCI; when the bit is 0, it indicates that the terminal does not need to detect the DCI.

302. The base station transmits a first group of beams, and the first group of beams have the function of carrying the indication information.

The first group of beams includes at least one beam, one time unit may correspond to one beam, and one time unit may also correspond to at least two or more beams, optionally, the time unit includes but is not limited to a slot, a subframe or an OFDM symbol, for example, the first group of beams includes 8 beams, each beam corresponds to one slot, and similarly, the number of beams in the first group of beams may also be 16 or 32, which is not limited in this application.

It is easy to understand that the time length corresponding to the first group of beams, i.e. the time unit corresponding to all beams in the first group of beams, includes 8 beams in the first group of beams, each beam corresponds to one slot, for example, and the time length of the first group of beams is 8 slots.

303. The terminal performs beam scanning over a first time period to obtain a beam scanning result.

The time length of the first time period is equal to the time length of the first group of beams, wherein the beam scanning performed by the terminal in the first time period may specifically be: the terminal scans all beams of the first set of beams or the terminal scans one or some of the beams of the first set of beams. Optionally, the beam scanning may be performed on one or more beams with better signal quality, where whether a signal of a beam is better may be determined according to a signal quality threshold, and a value of the signal quality threshold is not limited in this embodiment of the present application.

The terminal scans for beams over a first time period, i.e., the terminal scans for a first set of beams over the first time period. Specifically, the terminal may perform beam scanning on beams corresponding to part or all of the time units in the first time period.

Optionally, the first time period includes, but is not limited to, a paging occasion corresponding to the WUS, where one beam in the first time period corresponds to one WUS detection time, and if one slot corresponds to one WUS detection time, the terminal may perform beam scanning at the WUS detection time to determine whether the base station subsequently issues downlink control information.

304. And the terminal determines whether the indication information is detected on the first group of beams according to the beam scanning result, so as to determine whether the terminal needs to detect the downlink control information.

Optionally, in an indication manner: if the beam scanning result is that the indication information is detected on the first group of beams, determining that the terminal needs to detect the downlink control information; if the beam scanning result is that no indication information is detected on the first group of beams, it is determined that the terminal does not need to detect the downlink control information, and it is easy to understand that detecting the indication information on the first group of beams means detecting the indication information on one or more beams in the first group of beams, and that detecting no indication information on the first group of beams means detecting no indication information on any beam in the first group of beams. For example, taking the WUS signal and the DCI as an example, when the WUS signal is a ZC sequence, if the terminal detects the ZC sequence corresponding to the WUS signal on the first beam set, the terminal determines that the DCI needs to be detected subsequently; and if the terminal does not detect the ZC sequence corresponding to the WUS signal on the first group of beams, the terminal determines that DCI does not need to be detected subsequently. It is easy to understand that the information indication method indicates whether the terminal needs to detect the downlink control information by the presence or absence of the indication information itself.

Optionally, in another indication mode: when the beam scanning result is that the indication information is detected and the indication information indicates that the terminal needs to detect the downlink control information on the subsequent beam, determining that the terminal needs to detect the downlink control information on the subsequent beam; and when the beam scanning result is that the indication information is detected but the indication information indicates that the terminal does not need to detect the downlink control information on the subsequent beam, determining that the terminal does not need to detect the downlink control information on the subsequent beam. For example, when the WUS signal corresponds to a bit, if the terminal detects that the bit is 1, the terminal determines that DCI needs to be detected subsequently; and if the terminal detects that the bit is 0, the terminal determines that the DCI does not need to be detected subsequently. It should be understood that, this indication manner is to indicate whether the terminal needs to detect the downlink control information through the indication content corresponding to the indication information.

It should be noted that after determining that the terminal does not need to detect the downlink control information subsequently through the detection of the indication information, the terminal continues to monitor in the next time period (the duration of the time period may be the same as the first time period).

305. If the terminal needs to detect the downlink control information, the terminal selects a first beam from the first group of beams.

Optionally, when it is determined that the terminal needs to detect the downlink control information, the terminal selects one beam from the first group of beams as the first beam, it should be noted that the first beam includes but is not limited to a beam with good signal quality strength, and under the condition of poor signal quality, a plurality of beams in the first group of beams may also be used as the first beam. The selection of the first beam may be based on the signal quality strength corresponding to the beam.

It should be appreciated that when it is determined that the terminal does not need to detect the downlink control information, the terminal continues to listen to the first set of beams for the next first time period.

306. And the terminal determines a second beam according to the first beam, wherein the second beam is used for receiving the downlink control information.

After the terminal selects one beam from the first group of beams as a first beam, the terminal determines a second beam according to the first beam, wherein the second beam is at least one beam in a second group of beams, and the second group of beams has a function of carrying downlink control information.

Optionally, the determining the second beam according to the first beam may include: determining a target beam with the same beam identification as that of the first beam in the second group of beams as a second beam; or, a target beam with the same beam identifier as that of the first beam in the second group of beams is identified, and a beam adjacent to the target beam in the second group of beams is determined as the second beam, wherein the adjacent beam refers to a beam adjacent to the beam identifier of the target beam, and the like.

307. And the terminal receives the downlink control information in the time unit corresponding to the second wave beam.

The second beam is one or more beams in the second group of beams, and the plurality refers to two or more. The downlink control information may be downlink control information scrambled by the radio network temporary identity P-RNTI, that is, DCI corresponding to Paging information.

And after the terminal receives the DCI corresponding to the Paging information, receiving the Paging information of the base station according to the time-frequency resource indicated in the DCI, and acquiring a terminal identification list carried in the Paging information. When the terminal determines that the terminal identifier is in the terminal list in the Paging information, the terminal is paged by the base station, otherwise, the terminal is not paged by the base station. When the terminal is paged by the base station, if the terminal does not establish network connection with the network side, the terminal can initiate a random access request to try to access the network.

In the embodiment of the present application, after determining that the terminal needs to detect the downlink control information, the terminal may further determine the second beam through the first beam, and accurately obtain the time for issuing the downlink control information, so that, on the premise that the terminal needs to detect the downlink control information through the previously issued beam (i.e., the first group of beams), the book embodiment may further obtain an accurate time unit for issuing the downlink control information (i.e., a time unit corresponding to the second group of beams), thereby accurately detecting the downlink control information, improving the detection efficiency and the detection accuracy of the downlink control information, and finally achieving the purpose of saving electric energy.

In this embodiment of the present application, the number of beams, that is, the time length, corresponding to the first group of beams or the second group of beams may be variable, for example, when one group of beam scans includes 8 beams and one beam corresponds to one slot, the scanning time length of the group of beam scans is 8 slots; when a group of beam scanning comprises 6 beams and one beam corresponds to one slot, the scanning duration of the group of beam scanning is 6 slots; when a group of beam scans includes 4 beams, and one beam corresponds to one slot, the scanning duration of the group of beam scans is 4 slots, and so on.

In the embodiment of the present application, the time unit corresponding to the second group of beams may be the paging time as described above. Each time unit in the time units corresponding to the second group of beams corresponds to one beam or a plurality of beams, and the first time unit includes at least one PDCCH detection time, or one beam corresponds to one PDCCH detection time.

In this embodiment, in an embodiment, a time interval between the first group of beams and the second group of beams may be N times of a scanning period of one group of beams, where N is an integer greater than or equal to 1, where a value of N may be predefined, or may be configured by a network, for example, through signaling, such as RRC signaling, MAC-CE signaling, or through DCI. For example, if the scanning duration of the beam scanning is 5ms, the beam scanning may be performed every 20ms, in this case, the scanning period of the beam scanning is 20ms, and the time interval between the first time unit in the first time period and the first time unit in the second time period may be 20ms, 40ms, 60ms, and 80ms, and so on. Since the beam may be SSB, the scanning period of a group of beam scans may also be referred to as an SSB period.

It should be understood that the number of beams in the first set of beams is the same as the number of beams in the second set of beams, i.e. the number of time units corresponding to the first set of beams is the same as the number of beams corresponding to the second set of beams, and the time interval between the first set of beams and the second set of beams refers to the time interval between the respective opposite time units in the first set of beams and the second set of beams. Specifically, the time interval between the first group of beams and the second group of beams may be a time interval between a first time unit in the first time period and a first time unit in the second time period. The time interval between the first group of beams and the second group of beams may also be referred to as an offset value (offset), where the offset value may be predefined, or may be configured for the terminal by the base station through signaling or broadcast message.

In this embodiment of the present application, determining, as the second beam, a target beam in the second group of beams, where the beam identifier is the same as the beam identifier of the first beam may specifically be: for example, if the terminal determines the 2 nd beam in the first group of beams as the first beam, the terminal determines the corresponding 2 nd beam in the second group of beams as the second beam. Similarly, if the terminal determines the 2 nd and 3 rd beams of the first set of beams as the first beam, the terminal determines the corresponding 2 nd and 3 rd beams of the second set of beams as the second beam.

As shown in fig. 2, the change of the spatial direction of the 1 st beam to the spatial direction of the 8 th beam is changed in a clockwise direction, and it is understood that the change of the spatial direction of the 1 st beam to the spatial direction of the 8 th beam may also be changed in a counterclockwise direction. Taking the 8 beams corresponding to the 8 slots in the paging time described in fig. 2 as an example, in this embodiment of the application, determining a target beam in the second group of beams, where the beam identifier is the same as the beam identifier of the first beam, and a beam in the second group of beams, which is close to the target beam, as the second beam may specifically be: and determining one or more beams in the clockwise and/or counterclockwise direction as a second beam by taking the target beam with the same beam identification as that of the first beam in the second group of beams as the center. Taking the above-mentioned one group of beams shown in fig. 2 as an example of the second group of beams, if the 2 nd beam described in fig. 2 is a target beam having a beam identifier identical to that of the first beam, the 2 nd beam in fig. 2 and the 3 rd beam and the 4 th beam corresponding to the 2 nd beam in the clockwise direction may be determined as the second beam, or the 2 nd beam in fig. 2 and the 1 st beam corresponding to the 2 nd beam in the counterclockwise direction may be determined as the second beam, or the 2 nd beam in fig. 2, the 1 st beam corresponding to the 2 nd beam in the counterclockwise direction, the 3 rd beam and the 4 th beam corresponding to the 2 nd beam in the clockwise direction may be determined as the second beam.

In the embodiment of the present application, one first group of beams corresponds to at least one second group of beams, and optionally, the number of beams of the first group of beams is equal to the number of beams of the second group of beams; when a first group of beams corresponds to at least two second groups of beams, the number of second beams (i.e. the number of second beams) corresponding to each second group of beams has a positive correlation with the time interval between each second group of beams and the first group of beams. I.e., the longer the time interval between each second set of beams and the first set of beams, the greater the number of beams in the corresponding second set of beams and the longer the corresponding time interval. It can be known from the above that the time length corresponding to the second group of beams may be the paging occasion, and therefore, in a scenario where one WUS signal corresponds to multiple paging occasions, the time length of each paging occasion may increase with the increase of the time interval between the paging occasion and the time of transmitting the WUS signal, that is, the duration of each paging occasion may be dynamically adjusted and is not necessarily equal to the duration of each paging occasion.

In the embodiment of the present application, when one first group beam corresponds to at least one second group beam, the second beam number corresponding to each second group beam may be determined according to the initial beam number and the time interval between each second group beam and the first group beam group. Specifically, the first group of beams may start from an initial number of beams N0, the subsequent number of beams may be sequentially incremented by a fixed step S, S is an integer greater than or equal to 1, i.e., the number of beams in the first second group of beams is N0, the number of beams in the second group of beams is (N0+ S), the number of beams in the third second group of beams is (N0+ 2S), and so on, the number of beams in the nth second group of beams is (N0+ N S). It can also be understood that the duration of the first second group of beams is N0 time units, the duration of the second group of beams is (N0+ S) time units, the duration of the third second group of beams is (N0+2 × S) time units, and so on, the duration of the nth second group of beams is (N0+ N × S) time units. Fig. 4 is a schematic diagram illustrating a correspondence relationship between a first group of beams and a second group of beams according to an embodiment of the present application, where fig. 4 shows a case where N0 is 1 and S is 2.

In the embodiment of the present application, the correspondence between the PDCCH detection time corresponding to the second group of beams and the beams may be configured by the network side (e.g. the base station) through the beam pattern as described in fig. 2. Specifically, the network side may configure a plurality of patterns, and the network side configures the identifier of each pattern to the terminal, so that the terminal may determine the corresponding pattern according to the pattern identifier, and further determine the beam corresponding to the PDCCH detection time, taking fig. 2 as an example, 8 slots may represent 8 PDCCH detection times, and the terminal may determine the PDCCH detection time as the 1 st beam (i.e., the 1 st slot) in the paging time in fig. 2 according to the beam pattern in the north-south direction.

The above-mentioned patterns may include but are not limited to: a pattern of increasing SSBs counterclockwise and clockwise around the SSB of the WUS (i.e., the first beam), a pattern of increasing SSBs clockwise around the SSB of the WUS as the first beam, a pattern of increasing SSBs counterclockwise around the SSB of the WUS as the first beam, a pattern of increasing SSBs clockwise around the first SSB transmitted by the base station as the first beam, or a pattern of increasing SSBs counterclockwise around the first SSB transmitted by the base station as the first beam. As for the number of beams that the following PO increases from the length of the preceding PO depending on the length of the PO adjustment, i.e. the fixed step S, specifically, the 2 nd PO increases by 3 slots from the length of the 1 st PO, then the 2 nd PO will select the newly increased beam according to the network-side configured pattern, for example, the network-side configured pattern is: with the first SSB sent by the base station as a pattern in which the 1 st beam increases clockwise, then the 2 nd PO increases 3 more beams than the 1 st PO, where the 3 beams are 3 beams in the clockwise direction of the 1 st PO beam, that is, the 1 st PO includes 1 PDCCH detection time, which corresponds to the first SSB, the 2 nd PO includes 1+3 — 4 PDCCH detection times, and the SSBs corresponding to the 4 PDCCH detection times are respectively the 1 st, 2 nd, 3 rd, and 4 th SSBs.

The relationship between the PDCCH detection time and the SSB may be determined by the terminal according to its own status, specifically, the network side configures the terminal with multiple patterns, and different terminals may select to use one of the multiple patterns configured by the network side according to their own status. The state of the terminal includes a speed of the terminal and a moving direction of the terminal. For example, if the terminal determines to move itself away from the base station, the terminal may select a pattern that increases clockwise for the 1 st beam with the SSB of the WUS; if the terminal determines to move itself closer to the base station, the terminal may select a pattern that increases counterclockwise for the 1 st beam with the SSB of the WUS.

In an embodiment, the base station may turn on or off the dynamic adjustment mechanism of the PO duration through network side signaling, and only when the dynamic adjustment mechanism of the PO duration is turned on, the terminal may dynamically adjust the corresponding PDCCH detection time and the number of second beams, where one beam corresponds to one PDCCH detection time. For example, the base station may control the on or off of the dynamic adjustment mechanism by using a field of the dynamic adjustment mechanism that carries a time length for turning on or off the PO in a Radio Resource control configuration (RRC setup) signaling.

Further, the base station controls the dynamic adjustment mechanism on the premise that the terminal supports the dynamic adjustment mechanism, and if the terminal supports the dynamic adjustment mechanism, the base station may be turned on; otherwise, the base station cannot start the dynamic adjustment mechanism. The base station may learn, through the reported information of the terminal, whether the terminal supports the dynamic adjustment mechanism, for example, the terminal carries, in the RRC connection setup signaling for RRC connection configuration, indication information whether the terminal supports the dynamic adjustment mechanism.

In an embodiment, the size of the fixed step S is determined by a terminal status, wherein the terminal status may include, but is not limited to, a moving speed and a moving direction. For example, if the terminal determines that its moving speed is slow, the terminal may set S to 1, and if the moving speed of the terminal is fast, the terminal may set S to 3. The terminal determines the speed condition of the terminal according to the broadcast message or the configuration information of the network side. The network side broadcasts at least 1 speed threshold, and the terminal compares the speed with the speed threshold according to the speed, for example, if the speed is between the threshold 1 and the threshold 2, the UE sets S to 1, and if the speed is between the threshold 2 and the threshold 3, the UE sets S to 2.

It should be noted that the terminal in this embodiment may be a terminal in an idle state, or a terminal in a connected state or an inactive state, which is not limited in this application. Wherein, the idle state means that the UE and the network side have not established RRC connection, and the UE can monitor paging, execute cell measurement and cell selection, and acquire system messages; the connected state means that the UE establishes RRC connection with the network, the UE stores an air interface context, the UE and the network side can send unicast data mutually, and the UE detects a control channel and can further detect a shared data channel, perform channel measurement and feedback, perform cell measurement and feedback, acquire system information and monitor paging if necessary; the inactive state means that the UE establishes RRC connection with the network, the UE stores an air interface context, the network side configures an air interface notification range (radio access network based notification area) for the UE, and the UE can monitor paging, perform cell measurement and cell selection, acquire system information, and perform updating of the air interface notification range.

In this embodiment of the present application, the identifier of the beam may be an identifier of a time unit where the beam is located, or may be an identifier of a reference signal corresponding to the beam, where the reference signal may be a signal block composed of a synchronization signal and a broadcast signal, such as an SSB; there may be a one-to-one correspondence between time elements and beams, and the time elements may be at least one of slots, OFDM symbols, or subframes. Specifically, one time unit may be one slot, one OFDM symbol, one subframe, one millisecond ms, or one fractional millisecond, or may be multiple slots, multiple OFDM symbols, multiple subframes, multiple milliseconds ms, or multiple fractional milliseconds, where the fractional millisecond may be 1/4ms, 1/8ms, 1/16ms, 1/32ms, or 1/64ms, and so on. It should be noted that, in the embodiment of the present application, one slot may also include 2 or more than 2 beams, for example, 2 beams are included in one slot, and one time unit corresponds to a half slot at this time, and so on, that is, one time unit may be a fractional slot, for example, 1/2 slot, 1/3 slot, and so on.

It can be seen from the technical solutions of the above embodiments that the WUS signal is defined as a group of beam scans, and it is determined whether the terminal needs to detect the downlink control information from the first beam in the group of beams corresponding to the WUS signal through the embodiments of the present application. Therefore, the WUS mechanism applicable to NR is provided in the embodiments of the present application, so that before a base station issues downlink control information, a terminal is notified via a WUS signal, that is, indication information, in a first time period, so that the terminal can perform downlink control information detection only when there is downlink control information in a subsequent second time period, that is, a paging time PO, otherwise, the terminal does not detect, and therefore, power consumption of the terminal in detecting the downlink control information can be reduced and energy is saved by using the technical solution of the embodiments of the present application.

Further, in the embodiment of the present application, the second beam used for receiving the downlink control information on the second beam may be directly determined according to the first beam in the first group of beams, or it may be understood that the beam of the PO (i.e., the second beam) may be determined according to the beam of the WUS (i.e., the first beam), and therefore, the terminal does not need to continuously scan each beam in the second time period, so as to reduce power consumption.

Still further, in this embodiment of the present application, one first group of beams may correspond to multiple second groups of beams, and whether downlink control information exists on the multiple second groups of beams may be known through beam detection on the first group of beams, so that beam detection in the first time period is reduced, and power consumption may also be reduced. In addition, the possibility of overlapping the second time periods corresponding to different terminals in the time domain can be reduced by dynamically adjusting the number of the second beams, which is more beneficial to the configuration of the base station and better optimizes and configures transmission resources, thereby improving the information transmission efficiency.
