Description

Information processing method and information processing device

This application requires the priority of the Chinese patent application filed on November 26, 2018 in the China Patent Office with the application number 201811419248.6 and the invention titled "An Information Processing Method and Information Processing Device", the entire contents of which are incorporated herein by reference Applying.

Technical field

The present application relates to the field of communication technology, and in particular, to an information processing method and information processing device.

Background technique

In long term evolution (LTE), when the terminal does not establish a connection with the network side, the terminal will listen for paging messages on specific time-frequency resources and detect that the specific time-frequency resources of the paging message are detected. This is called paging moment (PO). When the terminal monitors the paging radio network temporary identifier (P-RNTI) scrambled downlink control information (DCI) on the PO, the terminal will check the time-frequency indicated by the P-RNTI DCI The paging message is received on the resource, and the terminal knows whether it is paged by the base station through the paging message.

In order to reduce the power consumption of the terminal and save power, a wake-up signal (WUS) mechanism was introduced in LTE. This WUS mechanism is used for the terminal to explicitly notify the terminal whether there is a PO on the PO before detecting the P-RNTI DCI on the PO P-RNTI DCI to avoid detection on POs without P-RNTI DCI.

A PO in LTE is a subframe subframe, and different terminals monitor the P-RNTI DCI on their corresponding POs. In the new generation access network (NR), beams are used for signal transmission between the base station and the terminal. One beam corresponds to one slot, and one PO corresponds to a group of beams. Different terminals will be on different beams. Receiving P-RNTI DCI, therefore, the above-mentioned WUS mechanism is not applicable in NR. In NR, it is necessary to provide a solution to clearly tell which beams different terminals know which P-RNTI DCI is on PO.

Summary of the invention

An embodiment of the present application provides an information processing method and an information processing device, which can learn in advance from the previous beam the specific time at which the downstream control information is delivered in the following beam, and then only after the detected by the previous beam The downlink control information is detected at a specific moment when the downlink control information is sent, so as to accurately control the detection of the downlink control information, avoid blind detection of the downlink control information, and save power.

In order to achieve the above technical objective, the embodiments of the present application provide the following technical solutions:

In a first aspect, an embodiment of the present application provides an information processing method, including: performing beam scanning in a first time period, where the first time period is a time period for scanning a first group of beams, and the first group of beams includes at least one Beam; further, according to the beam scanning result, determine whether the indication information is received on the first group of beams to determine whether the terminal needs to detect downlink control information. The first group of beams has the function of carrying the indication information, and the indication information is used to indicate whether the terminal The downlink control information needs to be detected. It should be understood that the function of the first group of beams to carry the indication information refers to that the first group of beams may carry the indication information or may not carry the indication information.

As can be seen from the technical solution in the first aspect above, the embodiments of the present application have the following advantages: In the first time period, it is learned whether the terminal needs to detect downlink control information by beam scanning, that is, whether there is a downlink in advance through beam scanning The control information is issued to avoid blind detection of the downlink control information by the terminal and unnecessary power consumption when detecting the downlink control information, so as to save power.

With reference to the first aspect, in a first possible implementation manner of the first aspect, the foregoing determines whether the indication information is received on the first group of beams according to the beam scanning result, thereby determining whether the terminal needs to detect the downlink control information includes the following two types Detection situation: First, the beam scanning result is that the indication information is received on the first group of beams, and it is determined that the terminal needs to detect the downlink control information.

Information; Second, the beam scanning result is that the indication information is received on the first group of beams, and the indication information indicates that the terminal needs to detect the downlink control information, then it is determined that the terminal needs to detect the downlink control information. Understandably, in this case, the indication is The content indicated by the information determines whether the terminal needs to detect downlink control information. When it is determined that the terminal needs to detect downlink control information, the first beam is selected from the first group of beams, and the first beam is used by the terminal to receive the indication information. Optionally, the first beam may be the beam with the best signal strength among the first group of beams.

The beam scanning result is that the indication information is not received on the first group of beams, and it is determined that the terminal does not need to detect the downlink control information. Understandably, this situation is based on Whether the instruction information is received to judge whether the terminal needs to detect the downlink control information; Second, the beam scanning result is that the instruction information is received on the first group of beams, but the instruction information indicates that the terminal does not need to detect the downlink control information, then determines that the terminal does not need to detect The downlink control information can be understood that in this case, the content indicated by the indication information is used to determine whether the terminal needs to detect the downlink control information.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following briefly introduces some concepts involved in the embodiments of the present application: a terminal, a beam, a paging paging, and a wake-up signal WUS.

The terminal referred to in this application is also called a terminal device, which can refer to a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem. Terminal devices can communicate with one or more core networks via a radio access network (RAN). Terminal devices can be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals For example, it may be a portable, pocket-sized, handheld, computer built-in or vehicle-mounted mobile device that exchanges language and/or data with the wireless access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (wireless local loop (WLL) stations, personal digital assistant (PDA), etc. . A wireless terminal can also be called a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a mobile station (mobile), a remote station (remote station), an access point (access point), Remote terminal (remote terminal), access terminal (access terminal), user terminal (user terminal), user agent (user agent) or user equipment (user equipment (UE)).

In various embodiments of the present application, a beam can be understood as a spatial resource, and can refer to a precoding vector for sending or receiving with energy transmission directivity. Moreover, the sending or receiving precoding vector can be identified by index information, which can correspond to the resource identity (ID) of the configuration terminal, for example, the index information can correspond to the configured synchronization signal block (synchronization sequence block) , SSB) identifier, or the identifier or resource corresponding to the channel state information reference signal (channel-state information-reference signal, CSI-RS); it can also be the identifier of the corresponding configured uplink sounding reference signal (sounding reference signal, SRS) Or resources. Optionally, the index information may also be index information displayed or implicitly carried by a signal or channel carried by a beam. The energy transmission directivity may refer to the precoding processing of the signal to be transmitted by the precoding vector, the signal after the precoding processing has a certain spatial directivity, and the precoding processing after receiving the precoding vector The signal has better received power, such as satisfying the reception demodulation signal-to-noise ratio, etc.; the energy transmission directivity may also mean that the same signal sent from different spatial positions received by the precoding vector has different received power. Optionally, the same communication device (such as a terminal device or a network device) may have different precoding vectors, and different devices may also have different precoding vectors, that is, corresponding to different beams. Regarding the configuration or capability of the communication device, one communication device may use one or more of multiple different precoding vectors at the same time, that is, one beam or multiple beams may be formed at the same time.

In the NR system, the frequency of the signal is higher. Compared with the low-frequency signal, the attenuation of the high-frequency signal is more obvious, and the energy loss during the signal transmission is greater. The high-frequency signal refers to a signal with a higher signal frequency, and the low-frequency signal refers to a signal with a lower signal frequency. The two are relatively relative. Generally speaking, the signal frequency of 6 GHz is used as the criterion for determining the high-low frequency signal. Signals with a signal frequency lower than 6 GHz are considered low-frequency signals, and signals with a signal frequency higher than or equal to 6 GHz are considered high-frequency signals. In the NR system, in order to solve the problem of reduced signal coverage and weakened signal strength caused by signal attenuation, the base station will send different beams in different directions in the space to improve the spatial coverage of the signal and enhance the signal strength . Similarly, the terminal performs beam scanning (beam sweeping) on the beams in the space to receive downlink information delivered by the base station.

In order to facilitate understanding of the beam scanning in the embodiment of the present application, the beam scanning will be described in detail below in conjunction with FIG. 1.

FIG. 1 is a schematic diagram of an embodiment of a group of beam scanning provided by an embodiment of the present application. As shown in Fig. 1, the base station transmits different beams in time order in different spatial directions. Since the transmission process of such beams is sent in time order, similar to scanning, it is called beam scanning. It is easy to understand that the signal spreads out into the surrounding space like a cone in space. The ellipse shown in FIG. 1 is essentially a cone, and the ellipse shown in FIG. 1 is just for convenience. In space, two beams in adjacent directions in a group of beams may be intersected or disjoint. Compared with the present application, there is no limitation.

Paging (Paging) means that a network device such as a base station is looking for a terminal. For example, when the network device has downlink information to be sent, the network device sends Paging information to the terminal, and the Paging information carries the terminal identification. If the terminal detects that its own identifier is in the above-mentioned Paging information, the terminal will send a request to the network device to access the network. The terminal in the idle state will listen to downlink control information (DCI) on a specific time-frequency resource. If the terminal detects that Paging information is delivered, the terminal receives Paging information according to the instructions in the DCI. Among them, the specific time domain resource used by the DCI corresponding to the monitoring Paging information is called paging opportunity (PO), and the paging opportunity is also called paging time. The time when the DCI is detected on the PO is usually called It is the physical downlink control channel (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 NR, the unit of PDCCH detection time is a slot. PO includes one beam sweeping, that is, a group of SSBs. One SSB corresponds to one PDCCH detection time. Therefore, one PO in NR includes at least one PDCCH detection time. It can also be understood that PO includes a group of beams, and one beam corresponds to a PDCCH detection time, and the patent is not limited to the understanding of PO. It should be noted that the DCI corresponding to the Paging information is generally downlink control information scrambled by the wireless network temporary identifier P-RNTI. The DCI scrambled by the P-RNTI may carry some information in the paging information. For example, the DCI scrambled by the P-RNTI may carry the indication information of whether the system information has changed, and/or the indication information of the emergency, in this case, The paging information can no longer indicate whether the system information has changed or whether there is an emergency.

The paging moment described above will be described in detail below with reference to FIG. 2, which is a schematic diagram of the paging moment PO provided by an embodiment of the present application.

As shown in FIG. 2, FIG. 2 shows the paging moment in the discontinuous period. The paging moment is shown in the gray part in FIG. 2. Further, FIG. 2 also shows a paging moment It consists of 8 slots, and the beam corresponding to each slot is shown in the black ellipse in Figure 2. The first beam is sent in the north direction of the base station on the first slot, and the second The beam is sent on the second slot to the base station's 45° east-north direction, the third beam is sent on the third slot to the east of the base station, and the fourth beam is sent on the fourth slot It is sent to the base station 45° east to the south, the fifth beam is sent to the south of the base station on the fifth slot, and the sixth beam is sent to the southwest of the base station on the sixth slot In the 45° direction, the seventh beam is sent in the seventh slot towards the west of the base station, and the eighth beam is sent in the eighth slot towards the base station in the 45° northwest direction, thus It is easy to understand that the signal coverage of the entire space is realized. In order to further improve the signal coverage effect, the number of beams can also be increased, and this application does not make any restrictions.

Wake-up signal (WUS) refers to a type of indication information used to indicate whether the terminal network device will send DCI corresponding to the Paging information on the PO. By detecting WUS, the terminal can know whether the network device will send the DCI corresponding to the Paging information on the PO. If yes, the terminal performs DCI detection on the corresponding PO, otherwise, the terminal does not perform detection, so as not to cause unnecessary power consumption and save power. It should be noted that WUS can be used to wake up the terminal under appropriate circumstances, and WUS can also be used to control the terminal to sleep under appropriate circumstances.

An embodiment of the present application provides an information processing system, and FIG. 3(a) is a system block diagram of the information processing system provided by the embodiment of the present application.

As shown in FIG. 3(a), it includes: a first information processing device and a second information processing device.

Among them, the first information processing device is mainly used for: performing beam scanning in a first time period, where the first time period is a time period for scanning the first group of one beam, and the first group of beams includes at least one beam; further, according to the beam scanning As a result, it is determined whether the indication information is received on the first group of beams to determine whether the terminal needs to detect the downlink control information. The first group of beams has a function of carrying the indication information. The indication information is used to indicate whether the terminal needs to detect the downlink control information.

The second information processing device is mainly used to: generate indication information used to indicate whether the terminal detects downlink control information; send a first group of beams, the first group of beams has a function of carrying the above indication information, and scan the first group The time period of the beam is the first time period, and the first group of beams includes at least one beam.

The information processing system shown in FIG. 3(a) is applicable to the LTE/5GC system architecture that supports simultaneous communication between the fourth-generation mobile communication system 4G and the fifth-generation mobile communication system 5G, and is also applicable to 5G (NR ) The system architecture can even be applied to the system architecture corresponding to the future mobile communication system, especially in the base station paging scenario of NR. The first information processing device includes but is not limited to a terminal or components in the terminal, and the second information processing device includes but is not limited to a base station or components in the base station.

In order to facilitate understanding of the information processing method provided by the embodiment of the present application, the following uses a base station and a terminal as examples to describe the information processing method in the embodiment of the present application in detail, as follows:

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

As shown in Figure 3(b), it includes:

301. The base station generates instruction information used to indicate whether the terminal detects 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 WUS may include a sequence, such as a ZC (zadoff-chu) sequence, or a signal, a pilot, or a signaling, only Need to have the function of indicating whether the terminal detects DCI delivery can be regarded as the instruction information described in this application.

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

302. The base station sends a first group of beams, and the first group of beams has a function of carrying the foregoing 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 correspond to at least two or more beams. Optionally, the time unit includes but is not limited to slot slot, subframe subframe, or OFDM Symbols, for example, the first group of beams includes 8 beams, and each beam corresponds to one slot. 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 length of time corresponding to the first group of beams is the time unit corresponding to all beams in the first group of beams. An above-mentioned first group of beams includes 8 beams, and each beam corresponds to a slot as an example. The length of time is 8 slots.

303. The terminal performs beam scanning on the 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, where the terminal performing the beam scanning on the first time period may specifically be: the terminal scans all beams in the first group of beams, or the terminal One or several beams in a group of beams are scanned. Optionally, the beam scanning may be performed on one or more beams with good signal quality, where whether the signal of the beam is good may be determined according to the signal quality threshold, but the value of the signal quality threshold in this embodiment of the present application is not Be limited.

The terminal performs beam scanning on the first time period, that is, the terminal scans the first group of beams on the first time period. Specifically, the terminal may perform beam scanning on beams corresponding to some or all time units in the first time period.

Optionally, the first time period includes but is not limited to the paging occasion corresponding to the WUS, where a beam on the first time period corresponds to a WUS detection moment, for example, a slot corresponds to a WUS detection moment, the terminal may be at the WUS detection moment Perform a beam scan to determine whether the base station subsequently sends downlink control information.

304. The terminal determines whether the above indication information is detected on the first group of beams according to the beam scanning result, thereby determining whether the terminal needs to detect downlink control information.

Optionally, in an indication mode: if the beam scanning result is that the indication information is detected on the first group of beams, it is determined that the terminal needs to detect downlink control information; if the beam scanning result is that the first group of beams is not detected Indication information, it is determined that the terminal does not need to detect the downlink control information, and it is easy to understand that the detection of the indication information on the first group of beams refers to the detection of the indication information on one or more beams in the first group of beams. No indication information detected on the beam means that no indication information is detected on any one beam in the first group of beams. For example, taking the above WUS signal and DCI as an example, when the WUS signal is a ZC sequence, if the terminal detects the ZC sequence corresponding to the above WUS signal on the first group of beams, the terminal determines that DCI needs to be detected subsequently; if 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 this kind of information indication method is to indicate whether the terminal needs to detect the downlink control information through the presence or absence of the indication information itself.

Optionally, in another indication mode: when the beam scanning result is detection indication information, and the indication information indicates that the terminal needs to detect downlink control information on the subsequent beam, it is determined that the terminal needs to detect downlink control information on the subsequent beam ; When the beam scanning result indicates 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, it is determined 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 the DCI needs to be detected later; 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 method is to indicate whether the terminal needs to detect downlink control information through the indication content corresponding to the indication information.

It should be noted that after the above detection of the indication information determines that the terminal does not need to detect downlink control information subsequently, the terminal will continue to listen in the next time period (the time period may be the same as the first time period).

305. If it is determined that the terminal needs to detect downlink control information, the terminal selects the first beam from the first group of beams.

Optionally, when it is determined that the terminal needs to detect 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 and strength. When the signal quality is poor, multiple beams in the first group of beams may also be used as the first beam. The first beam can be selected according to the signal quality strength corresponding to the beam.

It should be understood that when it is determined that the terminal does not need to detect the downlink control information, the terminal continues to monitor the first group of beams in the next first time period.

306. The terminal determines a second beam according to the first beam, and the second beam is used to receive downlink control information.

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

Optionally, the determining the second beam according to the first beam may include: determining a target beam having the same beam identifier as the second beam in the second group of beams as the second beam; or, determining the beam in the second group of beams Identify the target beam with the same beam ID as the first beam, and the beam in the second group of beams that is adjacent to the target beam position is determined to be the second beam, where the above-mentioned position close to means the beam position adjacent to the target beam Beam, and the beam adjacent to the adjacent beam of the target beam, and so on.

307. The terminal receives downlink control information on the time unit corresponding to the second beam.

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

After the terminal receives the DCI corresponding to the above-mentioned Paging information, it receives the Paging information of the base station according to the time-frequency resources indicated in the DCI, and obtains the terminal identification list carried in the Paging information. When the terminal determines that its own identity is in the terminal list in the above 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 a network connection with the network side, the terminal may 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 determine the second beam through the first beam to accurately know the delivery time of the downlink control information. Therefore, the embodiment of the book may On the premise that the transmitted beam (ie, the first group of beams) learns that the terminal needs to detect the downlink control information, it further knows the exact time unit (ie, the time unit corresponding to the second group of beams) to deliver the downlink control information, thereby accurately detecting the downlink control Information, improve the detection efficiency and detection accuracy of downlink control information, and ultimately achieve the purpose of saving power.

In the embodiment of the present application, the number of beams corresponding to the first group of beams or the second group of beams, that is, the length of time can be changed. For example, when a group of beam scans includes 8 beams, and one beam corresponds to one slot, the one The scanning duration of the group beam scanning is 8 slots; when a group of beam scanning includes 6 beams, and one beam corresponds to one slot, the scanning duration of the group beam scanning is 6 slots; when a group of beam scanning includes When there are 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 moment described above. Each time unit in the time unit corresponding to the second group of beams corresponds to one beam or multiple beams, and the first time unit includes at least one PDCCH detection time, or one beam corresponds to one PDCCH detection time.

In an embodiment of the present application, in an embodiment mode, the time interval between the first group of beams and the second group of beams may be N times the scanning period of the group of beam scans, and N is an integer greater than or equal to 1. , Where the value of N can be pre-defined, or can be configured by the network, such as through signaling, such as RRC signaling, MAC-CE signaling, or can be configured through DCI. For example, if the scan duration of the beam scan is 5 ms, the beam scan may be performed every 20 ms. At this time, the scan period of the beam scan is 20 ms. The first time unit in the first time period and the second time period in the second time period The time interval between a time unit can be 20ms, 40ms, 60ms and 80ms, and so on. Among them, since the beam can be an SSB, the scan period of a group of beam scans can also be called an SSB period.

It should be understood that the number of beams in the first group of beams and the second group of beams are the same, that is, the number of time units corresponding to the first group of beams is the same as the number of beams corresponding to the second group of beams. The time interval between refers to the time interval between the relative time units in the first group of beams and the second group of beams. Specifically, the time interval between the first group of beams and the second group of beams may be the time interval between the first time unit in the first time period and the 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 pre-defined, or may be configured by the base station through signaling or broadcast messages for the terminal of.

In the embodiment of the present application, determining the target beam with the same beam identifier as that of the first beam in the second group of beams as the second beam may specifically be: For example, both the first group of beams and the second group of beams include 8 If the terminal determines the second beam in the first group of beams as the first beam, then the terminal determines the corresponding second beam in the second group of beams as the second beam. Similarly, if the terminal determines the second beam and the third beam in the first group of beams as the first beam, then the terminal determines the corresponding second beam and the third beam in the second group of beams as the second Beam.

As shown in Fig. 2, the change from the spatial direction of the first beam to the spatial direction of the eighth beam is in a clockwise direction, and it is not difficult to understand that the spatial direction of the first beam to the eighth beam The change in spatial direction may also be in a counterclockwise direction. Taking the 8 beams corresponding to the 8 slots in the paging moment described in FIG. 2 as an example, in the embodiment of the present application, the beam identifier in the second group of beams is the same as the beam identifier of the first beam, And determining that the beam adjacent to the target beam position in the second group of beams as the second beam may specifically be: centering on the target beam with the same beam identifier as that of the first beam in the second group of beams, in accordance with the clockwise and /Or one or more beams in the counterclockwise direction are determined as the second beam. Taking the group of beams shown in FIG. 2 as the second group of beams as an example, if the second beam in FIG. 2 is a target beam with the same beam identifier as that of the first beam, then FIG. 2 The second beam in the middle, and the corresponding third beam and fourth beam in the clockwise direction according to the second beam are determined as the second beam, or the second beam in FIG. 2 and the second beam can also be The corresponding first beam in the counterclockwise direction is determined to be the second beam, or alternatively, the second beam in FIG. 2 according to the second beam in the counterclockwise direction corresponds to the first beam in accordance with the second beam. The corresponding third beam and fourth beam in the clockwise direction are determined as the second beam.

In the embodiment of the present application, one first group beam corresponds to at least one second group beam. Optionally, the number of beams of the first group beam is equal to the number of beams of the second group beam; when a first group beam corresponds to at least two For a second group of beams, the number of second beams corresponding to each second group of beams (that is, the number of second beams) has a positive correlation with the time interval between each second group of beams and the first group of beams . That is, the longer the time interval between each second group of beams and the first group of beams, the greater the number of beams in the corresponding second group of beams, and the longer the corresponding time length. It can be known from the above that the length of time corresponding to the second group of beams can be the above-mentioned paging occasion. Therefore, in the scenario where one WUS signal corresponds to multiple paging occasions, the length of each paging occasion can be different from that of the paging occasion. The time interval between the time when the WUS signal is sent increases and increases, that is, the duration of each paging opportunity can be dynamically adjusted and not necessarily the duration of each paging opportunity is equal.

In the embodiment of the present application, when a first group beam corresponds to at least one group of second group beams, the number of second beams corresponding to each second group beam may be based on the initial number of beams, and The time interval between the first group of beam groups is determined. It is understood that since the time unit and the beam are in one-to-one correspondence, the above initial beam number is the initial duration. Specifically, the first group of beams may start from an initial number of beams N0, and the number of subsequent beams sequentially increases with a fixed step size S, where S is an integer greater than or equal to 1, that is, the number of beams in the first second group of beams Is N0, the number of beams in the second second group of beams is (N0+S), the number of beams in the third second group of beams is (N0+2*S), and so on, and the Nth second group The number of beams in the beam is (N0+N*S). It can also be understood that, the duration corresponding to the first second group beam is N0 time units, the duration corresponding to the second second group beam is (N0+S) time units, and the duration corresponding to the third second group beam is The duration is (N0+2*S) time units, and so on. The duration corresponding to the N-th second group of beams is (N0+N*S) time units. FIG. 4 is a schematic diagram of the correspondence between a first group of beams and a second group of beams provided by an embodiment of the present application. FIG. 4 shows the case where N0=1 and S=2.

In the embodiment of the present application, the correspondence between the PDCCH detection time and the beam corresponding to the second group of beams may be configured by the network side (such as a base station) through the beam pattern as described in FIG. 2. Specifically, the network side can configure multiple patterns, and the network side configures the identification of each pattern to the terminal, so that the terminal can determine the corresponding pattern according to the pattern identification, so that the terminal can determine the corresponding pattern by the pattern identification, and then determine the PDCCH For the beam corresponding to the detection time, taking FIG. 2 as an example, 8 slots can represent 8 PDCCH detection times, and the terminal can determine the PDCCH detection time as the first beam in the paging time in FIG. (That is the first slot).

The above-mentioned patterns may include, but are not limited to: the pattern of increasing the SSB counterclockwise and clockwise with the center of the SUS (ie, the first beam) of the WUS, the pattern of increasing the SSB clockwise with the SSB of the WUS, and the pattern of the SSB of the WUS The first beam increases the SSB pattern counterclockwise, the first SSB sent by the base station is the first beam clockwise to increase the SSB pattern, or the first SSB sent by the base station is the first beam counterclockwise to increase the SSB pattern . As for the number of beams in the back PO increasing from the length of the previous PO depends on the length of the PO adjustment, that is, the fixed step size S, specifically, the second PO has an increase of 3 slots compared to the length of the first PO. Then the second PO will select the newly added beam according to the pattern configured on the network side. For example, the pattern configured on the network side is: the first SSB sent by the base station is the pattern that the first beam increases clockwise, then the second Compared with the first PO, the PO adds three more beams. These three beams are the three beams of the first PO beam clockwise. That is, the first PO includes a PDCCH detection time. This time corresponds to the first For one SSB, the second PO includes 1+3=4 PDCCH detection times, and the SSBs corresponding to these four PDCCH detection times are the first, second, third, and fourth SSBs, respectively.

The relationship between the PDCCH detection time and the SSB may be determined by the terminal according to its own state, specifically, the network side configures a variety of patterns for the terminal and different terminals may choose to use one of the various patterns configured by the network side according to their own state A pattern. Among them, the state of the terminal includes the speed of the terminal and the moving direction of the terminal. For example, if the terminal determines that it is moving away from the base station, the terminal may choose to use the WUS SSB as the first beam to increase the clockwise pattern; if the terminal determines that it is moving closer to the base station, the terminal may choose to use the WUS SSB as The pattern of the first beam increasing counterclockwise.

In an embodiment, the base station can enable or disable the dynamic adjustment mechanism of the PO duration through network signaling. Only when the dynamic adjustment mechanism of the PO duration is enabled, the terminal can 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 carry the field of the dynamic adjustment mechanism for turning on or off the length of the PO through Radio Resource Control (RRC) setup signaling to control the turning on or off of the dynamic adjustment mechanism.

Further, the premise that the base station controls the dynamic adjustment mechanism is that the terminal supports the dynamic adjustment mechanism. 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 can know whether the terminal supports the above-mentioned dynamic adjustment mechanism through the reported information of the terminal. For example, the terminal carries the indication information of whether the terminal supports the above-mentioned dynamic adjustment mechanism in the radio resource control connection configuration RRC connection signaling.

In an embodiment, the size of the fixed step S is determined by the terminal state, where the terminal state may include, but is not limited to, moving speed and moving direction. For example, if the terminal judges that its moving speed is slow, the terminal may set S to 1, and if the terminal moves fast, the terminal may set S to 3. Among them, the terminal determines its own speed situation according to the broadcast message or configuration information on the network side. The network side broadcasts at least one speed threshold. The terminal compares its own speed with the speed threshold. For example, if the threshold is between threshold 1 and threshold 2, the UE sets S to 1, and if the speed is between threshold 2 and threshold 3. Set S to 2.

It should be noted that, the terminal in the embodiment of the present application may be a terminal in an idle state, or a terminal in a connected state, or an inactive state, and this application does not make any limitation on this. The idle state means that the UE and the network side have not established an RRC connection. The UE can monitor paging, perform cell measurement and cell selection, and obtain system messages. The connected state means that the UE and the network have established an RRC connection, and the UE saves the air interface context. , The UE and the network can send unicast data to each other, the UE detects the control channel and then can detect the shared data channel, perform channel measurement and feedback, perform cell measurement and feedback, obtain system information, and monitor paging if necessary; inactive state refers to the UE The RRC connection is established with the network, the UE saves the air interface context, the network side configures the air interface notification range (radio access access network based notification area) for the UE, the UE can monitor paging, perform cell measurement and cell selection, obtain system messages, perform air interface notification Scope update.

In the embodiment of the present application, the beam identification may be the identification of the time unit where the beam is located, or the identification of the 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 SSB; time unit There may be a one-to-one correspondence with the beams, and the time unit may be at least one of slot, OFDM symbol, or subframe. Specifically, a time unit can be one slot, one OFDM symbol, one subframe, one millisecond ms, or one fractional millisecond, or multiple slots, multiple OFDM symbols, multiple subframes, multiple millisecond ms, Or multiple fractional milliseconds, where the fractional milliseconds 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, a slot may also include two or more beams. Taking a slot containing two beams as an example, a time unit corresponds to a half slot, and so on , That is, a time unit can be a fractional slot, such as 1/2 slot, 1/3 slot, etc.

It can be seen from the technical solutions of the above embodiments that the embodiment of the present application defines that the WUS signal is a group of beam scans, and it is clear from the embodiment of the present application whether the terminal needs to obtain the first beam from the group of beams corresponding to the WUS signal. Detect downlink control information. Therefore, the embodiments of the present application provide a WUS mechanism applicable to NR, to notify the terminal through the WUS signal that is the indication information in the first time period before the base station delivers the downlink control information, so that the terminal can only During the two time periods, that is, when there is downlink control information on the paging moment PO, the terminal performs the downlink control information detection, otherwise, the terminal does not detect it. Therefore, the technical solution of the embodiment of the present application can reduce the power consumption of the terminal to detect the downlink control information. Save energy.

Further, in the embodiment of the present application, the second beam 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 may be based on the WUS beam (ie The first beam) determines the beam of the PO (ie, the second beam). Therefore, the terminal does not need to continuously scan each beam in the second time period to reduce power consumption.

Still further, in the embodiment of the present application, one first group of beams can correspond to multiple second group beams, and the presence or absence of downlink control information on the multiple second group beams can be obtained by detecting the beams of the first group beams, thereby Reducing the detection of beams in the first time period can also reduce power consumption. In addition, by dynamically adjusting the number of second beams, the possibility of overlapping the second time period corresponding to different terminals in the time domain can be reduced, which is more conducive to the configuration of the base station and better optimizes the configuration of transmission resources, thereby improving information transmission efficiency.
