Description

Information processing method and device

Technical field

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

Background technique

At present, the parameter set (numerology) discussed in the new radio (NR) system is mainly applied to the frequency spectrum below 40 GHz. However, in order to obtain a larger bandwidth, it may be necessary to spread the spectrum in the future. For example, the NR-17 standard plans to discuss the spectrum above 52.6GHz. In the application scenario of the spectrum above 52.6GHz, the access network equipment and/or terminal equipment may use 480KHz or 960KHz subcarrier spacing when transmitting information. ,SCS).

At the same time, as the interval between subcarriers increases, a time slot occupies less and less time. Therefore, the terminal device may not have enough time to blindly detect as many physical downlink control channels (PDCCH) as possible, which impedes the application of parameter sets in high frequency or ultra-high frequency.

Summary of the invention

This application provides an information processing method and device, which are used to improve the efficiency of blind PDCCH detection by a first device.

In a first aspect, the present application provides an information processing method, the method includes: a first device receives configuration information sent by an access network device; wherein the configuration information includes a value X of an adjustment factor, and X is a positive integer; first The device detects the physical downlink control channel PDCCH in the search space period P and on any one or more of the at least two time slots. The search space period P is configured by the access network device; among them, at least two The time slot interval between two adjacent time slots for detecting PDCCH in the time slot is less than X.

Generally speaking, the processing capability of the first device per unit time is limited. If the PDCCH is placed on consecutive time slots, there are too many time slots per unit time, so it is impossible for the first device to detect all time slots. All PDCCH combinations. The technical solution provided by this application: the access network device places the PDCCH on the interval time slots, which can reduce the number of time slots in which the PDCCH exists in a unit time, so that the first device can have more time to blindly detect the PDCCH, thereby improving This improves the efficiency of the blind detection of the PDCCH by the first device.

Among them, PDCCH resources can be understood as: time-frequency resources that carry control information.

In a possible implementation manner, the value X of the adjustment factor satisfies at least the following conditions:

offset ₁ +X*D ₁ -(X-1)≤P ₁ ;

Among them, P ₁ is the first search space period configured by the access network device for the first device; offset ₁ is the offset value configured by the access network device, and the offset value is used to indicate that within the first search space period P ₁ The difference between the slot index of the PDCCH and the slot index of the first slot in the first search space period P ₁ for the first time, and offset _{1 is} greater than or equal to 0; D _{1 is} used to indicate that in the first search space period P ₁ The length of the time slot in which the PDCCH exists.

According to the above technical solution, although the PDCCH is placed in the interval time slot, by setting the value X of the adjustment factor, the first search space period P ₁ , the time slot length D ₁ and other parameters of the first device can still be compared with the current time slot. The search space configuration parameters in some standards or protocols are kept consistent, so that on the basis of solving the above technical problems and improving the efficiency of blind PDCCH detection by the first device, the technical solution is also kept as closely as possible with existing standards or protocols. Unanimous.

In a possible implementation manner, if the search space period P is configured as the second search space period P ₂ , the second search space period P ₂ at least satisfies the following conditions:

(offset ₂ +X*D ₂ -(X-1))*X≤P ₂ ;

Wherein, the second search space period P ₂ is the search space period configured by the access network device for the first device; offset ₂ is the offset value configured by the access network device, and the offset value is used to indicate the period in the second search space slot index difference between the first index of the first time slot by the presence of P ₂ PDCCH in the search space of the second period within the P ₂ and offset ₂ is greater than or equal to 0; D ₂ for indicating the second search The slot length of the PDCCH within the space period P _2.

Based on the above technical solution, by extending _{the size of the second search space period P 2} , not only can the PDCCH be placed on the interval time slots, reduce the number of time slots in which the PDCCH exists in a unit time, but also can further expand the blind detection. The PDCCH collection time in the search space period can further increase the time for the first device to blindly detect the PDCCH, and further increase the probability of the first device to successfully blindly detect the PDCCH in a search space period.

Among them, SCS ₁ is the subcarrier interval configured by the access network device, and the SCS ₁ is the subcarrier interval determined by the subcarrier interval index u1; SCS ₂ is the subcarrier interval used by the first device, and the SCS ₂ is the subcarrier interval used by the first device. The subcarrier interval determined by the subcarrier interval index u2; the subcarrier interval index u1 and/or the subcarrier interval index u2 are configured by the access network device or defined by the protocol.

In the embodiment of the present application, SCS ₁ can also be understood as: the reference subcarrier interval configured by the access network device for the first device, and SCS _{2 is} the subcarrier interval used by the first device. Optionally, the frequency used by the first device may be greater than or equal to 52.6 GHz.

In a possible implementation manner, in the search space period P, the first search space period P ₁ or the second search space period P ₂ , the time slot between any two adjacent time slots for detecting the PDCCH The interval is the same.

In the embodiment of the present application, by ensuring that the time slot interval between any two adjacent time slots for detecting the PDCCH is the same, the first device can clearly know that the time slot in which the PDCCH may exist.

In a second aspect, the present application provides an information processing method, the method includes: an access network device sends configuration information to a first device; wherein the configuration information includes a value X of an adjustment factor, and X is a positive integer;

The access network device sends the physical downlink control channel PDCCH to the first device within the search space period P and on any one or more of the at least two time slots. The search space period P is configured by the access network device ; Wherein, the time slot interval between two adjacent time slots for sending PDCCH in at least two time slots is less than X.

offset ₁ +X*D ₁ -(X-1)≤P ₁ ;

Wherein, the first search space period P ₁ is the search space period configured by the access network device for the first device; offset ₁ is the offset value configured by the access network device, and the offset value is used to indicate the period in the first search space The difference _{between the slot index of the PDCCH for the first time in P 1} and the slot index of the first slot in the first search space period P ₁ , and offset _{1 is} greater than or equal to 0; D _{1 is} used to indicate in the first search space period P ₁ in the memory slot length PDCCH.

(offset ₂ +X*D ₂ -(X-1))*X≤P ₂ ;

In a possible implementation manner, in the search space period P, the first search space period P ₁ or the second search space period P ₂ , the time slot between any two adjacent time slots for sending PDCCH The interval is the same.

It can be understood that the first device may also be a terminal device in a future 6G network or a terminal device in a future evolved PLMN, etc., which is not limited in this application.

The network architecture and business scenarios described in this application are intended to illustrate the technical solutions of this application more clearly, and do not constitute a limitation on the technical solutions provided in this application. Those of ordinary skill in the art will know that with the evolution of the network architecture and new services In the emergence of scenarios, the technical solutions provided in this application are equally applicable to similar technical problems.

Optionally, in the communication system shown in FIG. 1, the first device and the first device can also communicate through device-to-device (D2D), vehicle-to-everything (V2X), or Machine-to-machine (M2M) and other technologies are used for communication, and this application does not limit the communication method between the first device and the first device.

Based on the communication system shown in FIG. 1, the terms or methods involved in this application will be described in detail below.

Generally, the first device may determine the time-frequency domain resource information of the control channel based on the configuration information sent by the base station. Exemplarily, the control channel may at least include a physical downlink control channel (PDCCH), or a physical sidelink control channel (PSCCH), etc. For ease of description, the following will take the control channel as the PDCCH as an example to illustrate the method provided by this application.

Among them, the configuration information sent by the base station includes at least a control resource set (CORESET) and/or a search space (SS). Among them, the control resource set mainly includes frequency domain resources for configuring control channels, and information such as receiving beams.

Search space: It can be bound to any one or more configured control resource collections.

By controlling the resource set, the first device can know the approximate resource location allocated by the base station to the first device, but it does not know which resource set it is in. For example, it does not know which resources are allocated to the first device as a control channel. Which resources are allocated to the first device as the data channel. Therefore, the first device also needs a search space, detects the PDCCH of the first device according to the information of the search space (that is, the parameters configured in the search space are introduced below), and then determines the uplink and/or uplink and/or of the first device by the PDCCH Or the resource location of the downlink data channel and so on. Exemplarily, the relationship between the control resource set and the search space is shown in FIG. 2, and a search space can be bound to any one or more configured control resource sets. For example, the search space #1 in FIG. 2 can be bound to the control resource set #1, the search space #3 can be bound to the control resource set #2, and so on.

Through the search space, the first device can know on which time-frequency resource to detect the PDCCH. Among them, the PDCCH may be composed of one or more control channel element (CCE) resources, and there are multiple methods for CCE resources to form the PDCCH, which are called aggregation levels. For example, the value of the aggregation level may be any value in the set {1,2,4,8,16}, etc. In other words, a PDCCH may be aggregated by 1, 2, 4, 8, 16 and other CCEs.

Among them, one CCE may correspond to 6 resource element groups (REG); and one REG occupies one orthogonal frequency division multiplexing (OFDM) symbol in the time domain, and occupies 12 sub-groups in the frequency domain. Carrier. Further, in order to support flexible resource allocation on the base station side, the standard also allows the base station to configure frequency domain (frequency) discrete REGs; or, the time domain (time) occupies two or three OFDM symbols (symbol) REG and performs Bundle. As shown in Fig. 3, Fig. 3 shows a CCE that occupies two symbols in the time domain and is discrete/interleaved in the frequency domain. In addition to the binding format shown in Figure 3, the standard also supports the binding format shown in Figure 4.

However, for the first device, the first device cannot know the aggregation level and/or how the resource element group (REG) in each CCE is aggregated. In other words, the first device needs to obtain the aggregation level and the aggregation mode of resource element groups (REG) in each CCE through blind detection.

Therefore, the first device needs to perform blind detection on the control resource set resources configured by the base station, that is, the first device needs to perform blind detection on all possible PDCCH resources.

The first device may blindly check the PDCCH issued by the access network device according to the parameters configured in the search space. Among them, the search space configuration parameters may include but are not limited to:

controlResourceSetId: Represents the number of OFDM symbols (1 to 3) that exist on the PDCCH in a slot (slot);

monitoringSlotPeriodicityAndOffset: Represents the search space period and offset value (that is, the slot level offset within the period);

duration: indicates the length of the slot that the PDCCH may exist in a search space period;

monitoringSymbolsWithinSlot: indicates which symbols the first device starts to detect PDCCH in a slot;

nrofCandidates: indicates the CCE aggregation level.

The following example illustrates how the first device performs blind detection of the PDCCH according to the parameters configured in the search space.

For example, when controlResourceSetId: equal to 2;

monitoringSlotPeriodicityAndOffset: search space period Period=5 and offset value Offset=0;

duration: equal to 2;

monitoringSymbolsWithinSlot: equal to 100000100000;

nrofCandidates: equal to 1.

Based on the above parameters, from the perspective of the slot, monitoringSymbolsWithinSlot is 100000100000 indicating that the PDCCH may start from the first OFDM symbol and the seventh OFDM symbol, and the PDCCH is continuously placed on 2 OFDM symbols. That is, controlResourceSetId: equal to 2. Among them, 100000100000 represents a binary sequence; the above-mentioned parameters only indicate the initial symbol of the PDCCH placement, and do not indicate whether the PDCCH is placed on consecutive symbols. Exemplarily, as shown in Figure 5a, the PDCCH can be continuously placed on OFDM symbol 0 and OFDM symbol 1, and the PDCCH can also be continuously placed on OFDM symbol 7 and OFDM symbol 8, where the CCE aggregation level is 1, that is, nrofCandidates : Equal to 1. Therefore, a schematic diagram of the possible locations of the PDCCH in a time slot can be obtained as shown in Fig. 5a.

From the perspective of time slots, since the offset value Offset = 0, it means that the first device knows that in a search space period, there may be some data starting from the first time slot (that is, the time slot with the time slot index of 0). PDCCH. From duration: equal to 2, it can be seen that the PDCCH may exist on two consecutive time slots. For example, as shown in FIG. 5b, the PDCCH may exist on time slot 0 and time slot 1. And one search space period includes 5 time slots (because the search space period Period=5). Therefore, a schematic diagram of the possible locations of the PDCCH in a search space period can be obtained as shown in Fig. 5b.

Exemplarily, when the other parameters in Fig. 5a and Fig. 5b are unchanged, but the offset value Offset=2, that is, when the offset value is adjusted to 2, exemplarily, the PDCCH may exist in one search space period. The location diagram is shown in Figure 5c. Since Offset=2, there may be a PDCCH starting from the third time slot (that is, a time slot with a time slot index of 2), and the PDCCH may exist on 2 consecutive time slots. As shown in Figure 5c, the PDCCH may exist in time slot 2 and time slot 3.

It can be seen from FIG. 5a and FIG. 5b that the first device blindly detects the PDCCH sent by the base station to the first device on the time slot where the PDCCH may exist. For example, in a search space period, the PDCCH may exist in [0,1][7,8] OFDM symbols in the first slot, or it may exist in [0,1][ in the second slot. 7,8] OFDM symbols, so from a time point of view, that is, the first device needs to blindly detect the [0,1] OFDM symbols, [7,8] of the first slot in a search space period. OFDM symbols, [0,1] OFDM symbols and [7,8] OFDM symbols in the second slot, so the number of blind checks by the first device is 4 times. In addition, there is blind detection in the frequency domain, that is, the CCE aggregation level (1-16) needs to be considered. Therefore, the number of blind checks in one search space period is 4*CCE aggregation level.

Generally, in order to make the first device have consistent performance (that is, some first devices have strong processing capabilities, and some first devices have weak processing capabilities, the protocol defines a search capability that the first device must meet), the protocol defines the time slot level PDCCH blind detection capability. That is, the maximum number of blind detections of PDCCH candidates (candidates) of the first device in a time slot is shown in Table 1 below. And the maximum number of non-overlapping CCEs received by the first device in each time slot, as shown in Table 2 below.

Table 1

33	3232

Among them, u is the subcarrier spacing index. u = 0, 1, 2, 3 respectively represent the sub-carrier spacing of 15khz, 30khz, 60khz, and 120khz.

That is to say, Table 1 and Table 2 respectively indicate the maximum number of blind checks that the first device may have in each serving cell and each time slot.

However, in the case that all possible PDCCH resources configured by the base station are diversified, as the subcarrier spacing (SCS) continues to increase, the absolute time of a time slot (slot) is constantly shrinking. Therefore, it is difficult for the number of blind checks or the maximum number of non-overlapping CCEs of the first device in each time slot to meet the requirements of the above table. The fundamental reason is that the processing capacity of the components is limited, and it is difficult to complete the requirements shown in the above table in a shorter time.

If the PDCCH is still placed on consecutive time slots, the following two possibilities will appear. First, in order to solve the problem of the limited processing capability of the first device, the base station may further reduce the number of blind detections of the largest PDCCH candidate (candidate) in a time slot. For example, when u=4, each time slot The maximum number of blind checks for the candidate PDCCH may be 16 and so on. However, this will greatly reduce the resource flexibility that the base station can configure, thereby reducing the scheduling ability for multiple users. Second, regardless of the detection capability of the first device, the base station transmits PDCCH according to all possible combinations. In this way, the first device cannot detect all PDCCH combinations in all time slots due to its limited capability. Therefore, the efficiency of blindly detecting the PDCCH by the first device will become lower and lower.

Both of these may introduce negative effects. Therefore, this application places the PDCCH on discontinuous time slots or can also be referred to as PDCCH being placed on spaced time slots. Therefore, in the case of increasing SCS, the candidates on each time slot are not reduced as much as possible. The maximum number of blind checks for PDCCH. And because the PDCCH is placed on a discontinuous time slot, the first device has more time to blindly detect the PDCCH, thereby fully detecting all PDCCH combinations. Further, since the discontinuous time slot interval of the PDCCH is configurable, this application also greatly improves the flexibility of the base station to configure resources, and improves the scheduling capability for multiple users.

Generally, the parameter set (numerology) discussed in NR is mainly used for the frequency spectrum below 40Ghz. In the future 5G or 6G application scenarios, in order to obtain a larger bandwidth, the spectrum needs to be further extended to higher frequencies, such as the spectrum above 52.6Ghz. In this frequency band, a typical feature is that the bandwidth is large enough, and there may be a continuous spectrum above 2G available for use. Another feature is that the influence of phase noise is further increased, and higher-order SCS may be required to deal with the influence of phase noise. At present, the frequency spectrum below 40Ghz uses the highest subcarrier spacing of 240khz, but for the spectrum above 52.6Ghz, the value of 240khz is probably not enough. First, if the continuous spectrum above 2G, the base station and the first device may need The fast Fourier transform (FFT) size of 8192 points (obtained according to the bandwidth and sub-carrier spacing) is used to process continuous spectrum above 2G, which may be too high for the complexity of the system. The second is that the subcarrier spacing of 240khz and below may not be able to handle the more severe phase noise challenge. Therefore, the frequency spectrum above 52.6Ghz may use larger subcarrier spacing, such as 480khz and 960khz.

That is to say, as the subcarrier spacing increases, the first device may not have enough time to blindly detect all sets of PDCCH resources that may exist, and the efficiency of the first device to blindly detect the PDCCH may be very low. And when the capability of the first device cannot be greatly improved, using a subcarrier spacing SCS above 480KHz, the number of candidate PDCCHs and non-overlapping CCEs that the first device can blindly detect in each time slot will be extremely limited, making the traditional The slot-level scheduling mechanism cannot be implemented, which further limits the efficiency of the blind detection of the PDCCH by the first device.

Therefore, the present application provides an information processing method that can further extend the time for the first device to blindly detect the PDCCH set in a search space period when a large subcarrier interval (such as 480KHz or 960KHz or above) is used, thereby increasing The efficiency of the first device's blind detection of the PDCCH enables the first device to reuse the existing channel configuration and scheduling mechanism to the greatest extent; this method can further extend the time for the first device to blindly detect the PDCCH set in a search space period.

The following will take the access network device as the base station and the first device as the terminal device UE as an example to illustrate the information processing method provided in this application.

FIG. 6 is an information processing method provided by an embodiment of the present application. The method is applicable to the communication system shown in FIG. 1. As shown in FIG. 6, the method at least includes:

601. The base station sends configuration information to the UE; where the configuration information includes the value X of the adjustment factor, and X is a positive integer.

Correspondingly, the UE receives the configuration information sent by the base station.

Optionally, the configuration information may include the aforementioned search space configuration parameters, and the search space configuration parameters may be the parameters shown in FIG. 5a or FIG. 5b. Alternatively, the base station may also indicate to the UE the parameters of the search space configuration through other information. For example, downlink control information (DCI) may include the above-mentioned search space configuration parameters. For another example, radio resource control (Radio Resource Control, RRC) signaling may include the above-mentioned search space configuration parameters, etc. The present application does not limit the manner in which the base station indicates the search space configuration parameters to the UE.

Optionally, the configuration information may be included in DCI or RRC signaling. As for whether the parameters of the search space configuration and the configuration information are included in the same signaling at the same time, the embodiment of the present application does not limit it. For ease of description, the method shown in FIG. 6 will be described below by taking the configuration information including the parameters of the above search space configuration as an example.

Among them, the value X of the adjustment factor can also be understood as: an integer greater than zero.

Optionally, the value X of the adjustment factor satisfies at least the following conditions:

Among them, SCS ₁ is the subcarrier interval configured by the base station for the UE, and the SCS ₁ is the subcarrier interval determined by the subcarrier interval index u1; SCS ₂ is the subcarrier interval used by the UE, and the SCS ₂ is the subcarrier interval used by the UE. The subcarrier interval determined by the index u2; the subcarrier interval index u1 and/or the subcarrier interval index u2 are configured by the base station or defined by the protocol. Among them, the values of u1 and u2 can be integers. For example, the value of u1 can be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, etc.; and the value of u2 can be 0, 1, 2, 3, 4, 5, 6 , 7, 8, 9, and so on. Further, the relationship between the value of u1 and the interval of subcarriers may be: for example, SCS ₁ =15KHz*2 ^u1 ; and the relationship between the value of u2 and the interval of subcarriers may be: for example, SCS ₂ =15KHz*2 ^u2 . The relationship between the value of u1 and SCS ₁ can be shown in Table 3 below, where _{the value of u1 and/or SCS 1} can be configured by the access network equipment or defined by a standard or protocol; and the value of u2 and SCS _{The relationship of 2} can be shown in Table 4 below, where _{the value of u2 and/or SCS 2} can be configured by the access network device or defined by a standard or protocol. Table 3 or Table 4 are only examples, and other situations will not be listed one by one, and those skilled in the art can refer to relevant standards or protocol materials to obtain them.

It is understandable that with the development of future communication technologies, the relationship between u and subcarrier spacing may also change. Therefore, ^{the relationship of SCS=15KHz*2 u} shown above is only an example and should not be understood. It is a limitation of the embodiments of the present application.

The subcarrier interval configured by the base station for the UE, that is, SCS _1, can also be understood as: the reference subcarrier interval specified by the protocol, or the reference subcarrier used by the base station.

For example, the reference subcarrier interval used by the base station is 60KHz (that is, obtained by subcarrier index u1=2), and the subcarrier interval used by high frequency (greater than or equal to 52.6GHz) UE is 480KHz (that is, obtained by subcarrier index u2=5). ), the value of the adjustment factor X=480KHz/60KHz=8. Further, the slot interval between adjacent two slots with PDCCH in the above at least two slots is less than 8, for example, it can be any one of 7, 6, 5, 4, 3, 2, 1, or Multiple. In other words, the time slot interval between any two adjacent time slots in which the PDCCH exists may be the same or different. For example, when the base station transmits the PDCCH, it may transmit the PDCCH at a certain time slot interval, and the UE may detect the PDCCH at the certain time slot interval. Without loss of generality, the following will take as an example that the slot interval between any two adjacent slots with PDCCH is the same.

For another example, the reference subcarrier interval used by the base station is 120KHz (that is, obtained by subcarrier index u3=2), and the subcarrier interval used by the UE is 960KHz (that is, obtained by subcarrier index u2=6), then the value of the adjustment factor X=960KHz/120KHz=8.

For another example, if the reference subcarrier interval used by the base station is 120KHz, and the subcarrier interval used by the UE is 240KHz (that is, obtained by subcarrier index u2=3), then the value of the adjustment factor X=2. Further, the time slot interval between two adjacent time slots in which the PDCCH exists in the above at least two time slots is less than 2, for example, it can be 1.

For another example, if the reference subcarrier interval used by the base station is 120KHz, and the subcarrier interval used by the UE is 480KHz, the value of the adjustment factor X=480KHz/120KHz=4. Further, the time slot interval between two adjacent time slots in which the PDCCH exists in the above at least two time slots is less than 4, for example, it can be any one or more of 3, 2, and 1.

Optionally, the UE may report the specific value of the subcarrier interval that the UE expects or can use when reporting the capability information. For example, when the UE initially accesses, the capability information may be reported, and the capability information includes the subcarrier interval used by the UE, that is, SCS ₂ . Alternatively, the UE may also use the UCI to carry the subcarrier interval used by the UE, that is, SCS ₂ when sending uplink control information (UCI). It is understandable that how the UE reports the subcarrier interval used by the UE is not limited in the embodiment of the present application.

In order to understand the adjustment factor X more vividly, Table 5 shows how the adjustment factor X is obtained. It can be seen from Table 5 that the greater the subcarrier spacing, the smaller the length of a time slot, and the ratio of the subcarrier spacing to the length of a time slot is the same. Exemplarily, if SCS ₁ =60KHz and SCS ₂ =240KHz, then X=SCS ₂ /SCS ₁ =4. According to Table 5, it can be seen that the ratio of the time slot length is (0.0625/62.5)/(0.25/250)=4. That is to say, as the sub-carrier interval continues to increase, the absolute time of a time slot is getting shorter and shorter. Through the method provided in the embodiment of the present application, the PDCCH may be placed on the discontinuous interval time slot, which is the first device Provides more time for blind PDCCH detection, which improves the efficiency of PDCCH blind detection.

It can be understood that the aforementioned adjustment factor may also be referred to as an aggregation factor or an expansion factor, etc. The embodiment of the present application does not limit the name of the adjustment factor.

602. The base station sends a PDCCH to the UE in any one or more of the at least two time slots in the search space period; wherein, the search space period is configured by the base station, and at least two time slots are in phase. The time slot interval between two adjacent time slots for sending PDCCH is less than X.

Correspondingly, the UE detects the PDCCH in any one or more of the at least two time slots in the search space period; wherein, the search space period is configured by the base station, and at least two time slots are adjacent The time slot interval between the two time slots for detecting PDCCH is less than X.

It can be understood that the PDCCH can be used to carry downlink control information (DCI) or sidelink control information (SCI), etc., which is not limited in this application. And the UE detecting the PDCCH can also be understood as the UE blindly detecting the PDCCH and so on. The UE can obtain the DCI or SCI carried in the PDCCH by detecting the PDCCH.

In the embodiment of this application, placing the PDCCH on the interval time slots can reduce the number of time slots in which the PDCCH exists per unit time, that is, the first device has more time to blindly detect the PDCCH, thereby improving the blindness of the first device. Check the efficiency of PDCCH.

In the embodiment of the present application, based on the aforementioned adjustment factor, the PDCCH can be extended and placed on the interval time slots. Therefore, without loss of generality, some examples will be listed below to explain in detail the method shown in FIG. Various modifications of the examples should also be included in the scope of protection of this application.

method one,

The value X of the adjustment factor satisfies at least the following conditions:

offset ₁ +X*D ₁ -(X-1)≤P ₁ ;

Wherein, P ₁ is a base period for the first search space configured for the UE; offset _an offset value configured by the base station, the offset value for indicating the presence of the first time slot index PDCCH search space in _a first period and P The difference in the slot index of the first slot in the first search space period P ₁ _{, and offset 1 is} greater than or equal to 0; D _{1 is} used to indicate the slot length of the PDCCH in the first search space period P ₁ .

For example, the search space configuration parameters include the following parameters:

controlResourceSetId: equal to 2;

monitoringSlotPeriodicityAndOffset: search space period Period=10 and offset value Offset=2;

duration: equal to 3;

monitoringSymbolsWithinSlot: equal to 100000100000;

nrofCandidates: equal to 1.

Among the above search space configuration parameters, the value of Period can be understood as the first search space period P ₁ configured by the base station for the UE. As shown in FIG. 7, the first search space period P ₁ =10 (slots). The value of Offset can be understood as the offset value offset ₁ configured by the base station for the UE. As shown in FIG. 7, the offset value offset ₁ =2. In FIG. 7, the first index search space for the first time slot period P present in the PDCCH _is 2, the slot index within _a first time slot of the first search space period P 0, whereby the offset value offset ₁ =2-0=2. It can be understood that the time slot index shown in FIG. 7 is only an example, which is not limited in this application. For example, as shown in FIG. 7 slot index may be from 1 to 10, in this case, the first index search space for the first time slot period P present in the PDCCH ₁ to 3, a first search space ₁ the first period P The slot index of each slot is 1, so the offset value is offset ₁ =3-1=2. The value of duration can be understood as the time slot length D ₁ configured by the base station for the UE. As shown in Figure 7, the time slot length D ₁ is time slot 2, time slot 3 or time slot 4, that is, time slot length D ₁ =3.

As for the meaning of other parameters in the parameters of the search space configuration, reference may be made to the foregoing description, which will not be described in detail here.

Wherein, when the value X of the adjustment factor is not included in the configuration information, the possible location of the PDCCH is shown in FIG. 7.

The following will list some examples to illustrate the possible locations of the PDCCH when the value X of the adjustment factor is included in the configuration information.

Example 1:

When the configuration information includes the value X of the adjustment factor, and X=2, the possible location of the PDCCH is shown in FIG. 8a. That is to say, the base station can be used on the [0,1][7,8] OFDM symbols of the third time slot (slot index 2 in Fig. 8a) in the first search space period, and the fifth time slot. [0,1][7,8] on the [0,1][7,8] OFDM symbols of the slot (slot index 4 in Figure 8a) or [0,1] on the seventh slot (slot index 6 in Figure 8a) PDCCH is sent on [7,8] OFDM symbols. Correspondingly, the UE can blindly detect the position where PDCCH may exist, that is, the UE can perform blind detection on [0,1][7,8] OFDM symbols in the third slot and [0,1] in the fifth slot. PDCCH is detected on [7,8] OFDM symbols or on [0,1][7,8] OFDM symbols in the seventh slot.

It can be understood that when the value of the adjustment factor X=2 and SCS ₁ =15KHz, SCS ₂ =30KHz; alternatively, SCS ₂ =60KHz and so on. For another example, when SCS ₁ =30KHz, SCS ₂ =60KHz, or SCS ₂ =120KHz, etc., this embodiment of the application does not limit this.

Similarly, when the configuration information includes the value X of the adjustment factor, and X=3, the possible location of the PDCCH is shown in FIG. 8b. That is, the base station may search space in a first period P ₁ of the third slot (slot index 2 in FIG. 8b) [0,1] [7,8] OFDM symbols, sixty [0,1][7,8] of [0,1][7,8] on the OFDM symbols of the four time slots (slot index 5 in Figure 8b) or [0, 1] of the ninth time slot (slot index 8 in Figure 8b) 1] PDCCH is sent on [7,8] OFDM symbols. Correspondingly, the UE can blindly detect the position where PDCCH may exist, that is, the UE can perform the blind detection on [0,1][7,8] OFDM symbols in the third slot and [0,1] in the sixth slot. ] [7,8] OFDM symbols or [0,1][7,8] OFDM symbols in the ninth slot to detect PDCCH.

Example 2:

When the search space period (Periodicity)=11 included in the configuration information and the value X=4 of the adjustment factor included in the configuration information, the possible location of the PDCCH is shown in FIG. 8c. That is to say, the base station can be used on the [0,1][7,8] OFDM symbols of the third time slot (slot index 2 in Fig. 8c) in the first search space period, and the seventh time slot. [0,1][7,8] on the [0,1][7,8] OFDM symbols of the slot (slot index 6 in Figure 8c) or [0,1 on the eleventh slot (slot index 10 in Figure 8c) ] [7,8] PDCCH is transmitted on OFDM symbols. Correspondingly, the UE can blindly detect the position where PDCCH may exist, that is, the UE can perform blind detection on [0,1][7,8] OFDM symbols in the third slot and [0,1] in the seventh slot. PDCCH is detected on [7,8] OFDM symbols or [0,1][7,8] OFDM symbols in the eleventh slot. It can be understood that other parameters in the configuration information can refer to Example 1.

It can be understood that under the condition that the length of the time slot remains unchanged, it can be seen from the above example that offset ₁ +X*D ₁ -(X-1)≤P ₁ .

In a possible implementation manner, considering extreme conditions, for example, the subcarrier interval used by the UE may be much larger than the subcarrier interval configured by the base station, and the time slot interval is X-1, then the base station can reduce the PDCCH when sending PDCCH. The time slot with the PDCCH, if there is a PDCCH, there is at least one time slot. That is to say, the time slot in which the PDCCH exists can be m time slots such as 1 time slot, 2 time slots, 3 time slots, etc. The m is greater than or equal to 1, and the m is less than or equal to the time slot length (duration ). For example, if the adjustment factor X=4, and the slot interval between two adjacent slots with PDCCH in at least two slots is X-1=3, then if the first search space period P ₁ is still taken The value is 10 time slots, and the value of the time slot length D ₁ is 3 time slots, and the value of the offset value offset ₁ is 2 time slots as an example. If the above method is still used, the PDCCH may exist On the third time slot, the seventh time slot, or the eleventh time slot of the first search space period. However, since the value of the first search space period P ₁ is 10 time slots, it is impossible for the eleventh time slot to exist in the first search space period. Therefore, when the base station transmits the PDCCH, it can appropriately reduce the time slots in which the PDCCH exists. For example, when the base station transmits the PDCCH, it may send the PDCCH search space in a first period P on the third and seventh time slots ₁ time slot. Correspondingly, the UE may blindly detect the position where the PDCCH exists. Wherein, the possible location of the PDCCH is shown in Figure 8d. It can be understood that the position of the PDCCH in the time slot can refer to other parameters in the parameters of the search space configuration. As for the specific description of the other parameters, refer to the foregoing description, which will not be described in detail here.

That is to say, if it is ensured that the search space period in the configuration information remains unchanged, and the slot interval between two adjacent slots with PDCCH in at least two slots is X-1, then the configuration information The length of the included time slot can be appropriately reduced.

For another example, if the adjustment factor X=8, and the slot interval between two adjacent slots with PDCCH in at least two slots is X-1=7, then if the first search space period is still P ₁ The value is 10 time slots, and _{the value of the time slot length D 1} is 3 time slots, and the value of the offset value offset ₁ is 2 time slots as an example. Since the offset value offset ₁ +X*D ₁ -(X-1) is much larger than the first search space period P ₁ , when the base station transmits the PDCCH, it can appropriately reduce the time slots where the PDCCH exists. There can be one gap, as shown in Figure 8e. The time slot in which the PDCCH first exists in the first search space period P ₁ is the third time slot, and the time slot interval between the third time slot and the tenth time slot is 7, which is exactly equal to at least two time slots The time slot interval between two adjacent time slots in which the PDCCH exists is 7, therefore, there is one time slot in which the PDCCH exists.

In a possible implementation manner, according to the time slot length (duration) in the parameters of the search space configuration, the possible position of the PDCCH is located _{at D 1} time slot after the _{offset value of offset 1} time slot, as shown in the figure The 3rd time slot, the 4th time slot and the 5th time slot in 7. Therefore, considering that the possible location of the PDCCH remains unchanged as much as possible, when the base station transmits the PDCCH, the time slot where the PDCCH exists can be reduced. For example, there is at least one time slot where the PDCCH exists. For example, if the adjustment factor X=2, _{the value of the first search space period P 1} is still 10 time slots, and _{the value of the time slot length D 1} is 3 time slots as an example. Method, the PDCCH may exist in the third time slot, the fourth time slot, or the fifth time slot of the first search space period. If it is ensured that the possible location of the PDCCH remains unchanged as much as possible, and the PDCCH is placed on a non-contiguous time slot, the possible location of the PDCCH is shown in Figure 8f, that is, it is ensured that the PDCCH exists in the third time slot and the first time slot. In the five time slots, it is also ensured that the time slot interval between two adjacent time slots in which the PDCCH exists in at least two time slots is X-1=1. For another example, if the adjustment factor X=3, the first search space period P ₁ =10, and the slot length D ₁ =3, if the method shown in FIG. 5c is still used, the PDCCH may exist in the third search space period. Time slot, the fourth time slot, or the fifth time slot. If it is ensured that the possible location of the PDCCH remains unchanged as much as possible, and the PDCCH is placed on a non-contiguous time slot, then the possible location of the PDCCH is shown in Figure 8g, that is, to ensure that the PDCCH exists on the third time slot At the same time, it is ensured that the time slot interval between two adjacent time slots with PDCCH in at least two time slots is X-1=2.

In the first method, the UE can detect the PDCCH according to the configuration information (including the value of the adjustment factor) sent by the base station to ensure that the position where the PDCCH may exist is consistent with the position indicated in the configuration information. For example, the period of the search space is guaranteed to be unchanged, and the length of the time slot is guaranteed to be unchanged. However, the embodiment of the present application also provides an information processing method, which not only allows the PDCCH to be extended and placed on the interval time slot, but also can further extend the search space period.

Method Two,

If the search space period P is configured as the second search space period P ₂ , the second search space period P ₂ at least satisfies the following conditions:

(offset ₂ +X*D ₂ -(X-1))*X≤P ₂ ;

Wherein, the second search space period P ₂ is the search space period configured by the base station for the first device; offset ₂ is the offset value configured by the base station, and the offset value is used to indicate that the PDCCH exists for the first time _{in the second search space period P 2} The difference between the slot index and the slot index of the first slot in the second search space period P ₂ , and offset _{2 is} greater than or equal to 0; D _{2 is} used to indicate that there is in the second search space period P ₂ The slot length of the PDCCH.

controlResourceSetId: equal to 2;

duration: equal to 3;

monitoringSymbolsWithinSlot: equal to 100000100000;

nrofCandidates: equal to 1.

Among the above search space configuration parameters, the value of Offset can be understood as the offset value offset ₂ configured by the base station for the UE, that is, the offset value offset ₂ =2. The value of duration can be understood as the time slot length D ₂ configured by the base station for the UE, that is, the time slot length D ₂ =3. Wherein, when the configuration information includes the value X of the adjustment factor, the search space period configured by the base station for the UE, that is, the second search space period P _{2 is} related to the value X of the adjustment factor. That is, (2+X*3-(X-1))*X≤P _2. It can be seen from this formula that _{the value of the second search space period P 2} can be proportional to the value X of the adjustment factor.

In order not to change the definition of existing standards or protocols to the greatest extent, in a possible implementation, the search space configuration parameters still include the search space period P, which is the value of the above search space period Period. When the search space is configured When the parameter includes the value X of the adjustment factor or when the value X of the adjustment factor is determined by other methods, _{the value of the second search space period P 2} may be determined according to the value X of the adjustment factor. The value of the second search space period P ₂ can be configured by means of new indication signaling or adding additional indication information to the existing indication signaling. In another possible implementation manner, _{the value of the second search space period P 2} can be directly configured in the search space configuration parameter, which is not limited in this application.

Example 1:

As an example, when the configuration information includes the value X of the adjustment factor, and when X=2, (2+X*3-(X-1))*X≤P ₂ can be transformed into: (2+2*3 -(2-1))*2≤P ₂ , that is, P _{2 is} greater than or equal to 14. And when the value of the adjustment factor X=2, the slot interval between two adjacent slots in which the PDCCH exists in at least two slots is X-1=1. As an example, the possible location of the PDCCH is shown in Figure 9a. Exemplarily, the possible location of the PDCCH may also be as shown in FIG. 9b _{, and the value of the second search space period P 2} shown in FIG. 9b is 20 time slots, etc., which is not limited in the embodiment of the present application. It can be understood that, in Fig. 9a, the second search space period P ₂ includes 14 time slots, and in Fig. 9b, the second search space period P ₂ includes 20 time slots.

Optionally, the second search space period P ₂ may also be proportional to the search space period P in the search space configuration parameter, that is, the value of the search space period Period mentioned above. For example, in the example shown in FIG. 9a and/or FIG. 9b, the search space period Period=10, that is, the search space period P=10, then _{the value of the second search space period P 2} may be the value of the search space period P For example, the value of the second search space period P ₂ can be 3*10 equal to 30 time slots. For another example, the value of the second search space period P ₂ may be 4 times the value of the search space period P. For example, the value of the second search space period P ₂ may be 4*10 equal to 40 time slots.

Optionally, when the second search space period P ₂ is proportional to the value of the search space period P in the search space configuration parameter, the number of time slots in which the PDCCH may exist in the _{second search space period P 2 may be time} Integer multiples of the gap length (duration). For example, the number of time slots in which PDCCH may exist in the second search space period P ₂ may be equal to the value of the time slot length, or the number of time slots in which PDCCH may exist in the second search space period P ₂ may be the value of the time slot length. Or, the number of time slots in which the PDCCH may exist in the second search space period P ₂ may be 3 times the value of the time slot length, and so on.

Example 2:

In a possible implementation manner, when the configuration information includes the value X of the adjustment factor, for example, when X=4, at least two of the adjacent time slots with the PDCCH The time slot interval is X-1=3. Therefore, when the search space period P, that is, Period=10, can be configured as the second search space period P ₂ , the P ₂ at least needs to meet the following conditions, for example: (2+X*3-(X-1))*X ≤P ₂ , that is, (2+4*3-(4-1))*4≤P ₂ , then P _{2 is} greater than or equal to 44.

However, since the search space period P in the search space configuration parameter is set to 10, that is to say, within the 10 time slots indicated by the search space period P, if it is necessary to ensure that at least two adjacent time slots exist The time slot interval between the two time slots of the PDCCH is 3 time slots, so within the 10 time slots, there are only two time slots in which the PDCCH may exist. Therefore, in a possible implementation manner, if the _{number of time slots in which PDCCH may exist in the second search space period P 2} is equal to the time slot length (duration), then the second search space period P _{2 is} at least greater than the search space configuration parameter The value of the search space period P in the middle. Exemplarily, if the value of the second search space period P ₂ is twice the value of the search space period P in the parameters of the search space configuration, that is, the position where the PDCCH may exist is shown in FIG. 9c.

Example 3:

In a possible implementation manner, when the configuration information includes the value X of the adjustment factor, and X=2, take the description of FIG. 8f as an example, that is, when the base station transmits the PDCCH, it can reduce the time slots in which the PDCCH exists. If there is at least one PDCCH time slot. For example, the time slot length D ₂ =3 in the parameters of the search space configuration, the base station can reduce the time slots with the PDCCH when transmitting the PDCCH, and reduce the time slots with the PDCCH to two if there is a PDCCH. In this case, if the search space period is configured as the second search space period P ₂ , that is, in the case of expanding the search space, _{the value of the second search space period P 2} is at least greater than the search space period in the search space configuration parameter The value of P. Exemplarily, when the value of the search space period P is 10 time slots, the value of the second search space period P ₂ is greater than the value of the search space period P is 20 time slots, the position where the PDCCH may exist As shown in Figure 9d.

In a possible implementation manner, when the configuration information includes the value X of the adjustment factor, and X=3, take Figure 8g as an example for illustration, that is, to ensure that the possible location of the PDCCH remains unchanged as much as possible, When the base station transmits the PDCCH, it can reduce the time slot where the PDCCH exists. For example, there is at least one time slot where the PDCCH exists. Assuming that the time slot length D ₂ =3 in the search space configuration parameter, and the time slot interval between two adjacent time slots with PDCCH in at least two time slots is 2, then the search space period is configured as the first In the second search space period P ₂ , that is, in the case of extending the search space period, _{the value of the second search space period P 2} is at least greater than the value of the search space period P in the search space configuration parameters. Exemplarily, when the value of the search space period P is 10 time slots, and the value of the second search space period P ₂ is greater than the value of the search space period P 20 time slots, the possible location of the PDCCH is as Shown in Figure 9e.

It can be understood that, in the examples shown above, the second search space period may increase according to the increase of the value X of the adjustment factor, and may also increase according to the increase of _{D 2.} Taking into account the extreme situation, each of the time slots included in the search space period P in the search space configuration parameters is expanded by X times, and the second search space period can be obtained to satisfy (offset ₂ +X*D ₂ -( X-1))*X≤P ₂ .

It can be understood that in each of the examples shown above, the time slot interval between two adjacent time slots with PDCCH in at least two time slots is X-1, but the time slot interval is only an example, and the implementation of this application For example, the specific value of the time slot interval is not limited.

It can be understood that when the base station transmits the PDCCH according to the above method, because the position of the PDCCH has changed, for example, the PDCCH is extended and placed on the interval time slot. Correspondingly, the physical downlink shared channel (PDSCH) sent by the base station will also change accordingly. Therefore, when the UE receives the configuration information sent by the base station, it can also learn the time slot in which the PDSCH exists according to the configuration information. For example, when the base station informs the UE through DCI that the duration of the PDSCH configured for the UE is 1 slot, the UE can learn that the actual PDSCH duration may be (X-1) slot when the value X of the adjustment factor is known. .

Further, there may be no PDCCH in an entire time slot for transmitting PDSCH. For example, in the search space configuration parameter, the value of the search space period P is 10 time slots (that is, the search space period Period=10) , The value of the offset value is 2 time slots (that is, the offset value Offset=2), and the value of the time slot length is 2 time slots (that is, duration: equal to 2), and the OFDM where the PDCCH exists in a time slot When the number of symbols is 2 (ie controlResourceSetId: equal to 2), and the PDCCH may start from the first OFDM symbol (ie monitoringSymbolsWithinSlot: equal to 100000000000), the PDCCH may exist when the value X of the adjustment factor is not included in the configuration information The location is shown in Figure 10a. As shown in FIG. 10a, in the seventh time slot in the search space period, the base station does not send the PDCCH, and the first symbol in the time slot is to send a demodulation reference signal (DMRS). In this case, in a possible implementation manner, the method 1 shown in the foregoing is applied, for example, the value of the adjustment factor included in the configuration information is X=5, and there are two adjacent PDCCHs in at least two time slots. The time slot interval between time slots is less than X-1=4, if the time slot interval between two adjacent time slots with PDCCH in the at least two time slots is 3, as shown in FIG. 10b. It can be seen from Figure 10b that the base station may send the PDCCH on the seventh time slot. That is to say, the first few symbols (0 to 3) in the seventh time slot may be used to transmit the PDCCH. Therefore, the base station may place the DMRS on the symbols after the PDCCH is postponed. For example, for PDSCH of type A, DMRS may exist on the first few symbols in a slot. In a possible implementation manner, the method 2 shown in the foregoing is applied, for example, the value of the adjustment factor included in the configuration information is X=5, and at least two of the adjacent time slots have a PDCCH. The interval between the time slots is less than X-1=4. If the interval between the two adjacent time slots with the PDCCH in the at least two time slots is 3, as shown in Fig. 10c. It can be understood that when the method 1 and method 2 shown in the foregoing are applied, since the PDCCH may exist in multiple ways, there may be other ways in which the DMRS is located, which is not limited in this application.

Optionally, the base station is additionally configured with a factor Y, which can be used to indicate the location of the DMRS. For example, in Figure 10b, the factor Y can be 3, which means that the DMRS is located on the third symbol of the seventh time slot. Alternatively, the factor Y can also be 2, which means that the MDRS is located on the symbol with index 2 in the seventh slot. That is to say, if the UE detects that there is an extended PDCCH, the DMRS may exist on the OFDM symbol additionally configured by the base station.

It is understandable that in the examples shown above, some examples are based on the example that the slot interval between two adjacent slots in which the PDCCH exists in at least two slots is equal to X-1. However, the at least two slots The time slot interval between two adjacent time slots in which PDCCH exists can also be less than X-1, such as X-2, X-3, X-4,..., 1, etc., which is not limited in this application. All variations of the relationship between the time slot interval and the adjustment factor are included in the protection scope of this application.

It can be understood that the value of the adjustment factor X in the present application is not limited to the examples shown above, and the value of the adjustment factor X can also be other larger values.

The technical solution provided by this application: the base station can make the UE blindly detect the PDCCH in the spaced timeslot by placing the PDCCH on the spaced timeslot, so that the UE has enough time to blindly detect the collection of PDCCH resources; avoid When the base station continuously sends the PDCCH, because the UE does not have enough time to detect the PDCCH, the blind detection efficiency is low.
