Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method for sending a wake-up signal sequence and related devices. Background Art

[0002] In a wireless communication system, a communication device has two states: one is the connected state, which means that the communication device has established a connection with the network device and can communicate directly; the other is the idle state or sleep state, in which the communication device cannot communicate directly with the network device. In order to ensure that the network device can effectively find the communication device in the idle state, the network device generally uses paging, that is, regularly sends a paging signal to the communication device to indicate whether the communication device should switch from the idle state to the connected state in order to communicate with the network device. Figure 1 As shown, a communication device in idle state will periodically wake up to monitor paging signals. This period of periodic waking is called a discontinuous reception (DRX) cycle, and the DRX cycle can be indicated to the communication device via system messages. The time when the communication device wakes up during the DRX cycle is called a paging opportunity (PO). For an idle communication device, it is dormant for most of the DRX cycle and only wakes up at the PO to monitor the physical downlink control channel (PDCCH). The communication device first checks the paging common search space (Paging CSS). If a PDCCH is detected in the Paging CSS, the communication device receives the physical downlink shared channel (PDSCH) based on the indication information carried by the detected PDCCH. If no PDCCH is detected in the Paging CSS, the communication device does not need to receive the PDSCH.

[0003] Narrowband Internet of Things (NB-IoT) introduced a wake-up signal (WUS) in R15. WUS is used to indicate whether the communication device should wake up at the PO to detect the PDCCH. Figure 2As shown, on the network device side, when the network device needs to page the communication device or when a system message changes, the network device will send a WUS at least one gap before the PO; otherwise, the network device will not send any signal. On the communication device side, the WUS will be monitored before the PO. If a WUS is detected, the communication device will detect the PDCCH at the PO; if no WUS is detected, the communication device will not detect the PDCCH at the PO.

[0004] NB-IoT also stipulates in R15 that there is a gap between the end of the maximum WUS duration and the start of the PO, also known as the WUS gap. Network equipment can be configured with up to three gaps. Figure 3 As shown, the network device configures the communication device into two categories according to the capabilities of the communication device, namely, DRX communication device and eDRX communication device, wherein the DRX gap corresponding to the DRX communication device comes from the set {40ms, 80ms, 160ms, 240ms}, the DRX short gap (eDRX short gap) corresponding to the eDRX communication device comes from the set {40ms, 80ms, 160ms, 240ms}, and the DRX long gap (eDRX long gap) corresponding to the eDRX communication device comes from the set {1s, 2s}.

[0005] The communication device calculates the PO to which it belongs based on the identity (ID), and multiple communication devices may belong to the same PO. According to the existing protocol, when the network device pages any communication device in the PO, it will send a WUS, and once the communication device detects the WUS, it will be awakened. For example, assuming that 100 communication devices (numbered 0-99) belong to the same PO, the network device will send a WUS before the PO to wake up communication device No. 0. If all 100 communication devices detect the WUS, then all 100 communication devices will be awakened. In fact, communication devices No. 1-99 do not need to be awakened, so it is a "false alarm" for communication devices No. 1-99, which increases the power consumption of the communication devices.

[0006] NB-IoT introduced the concept of grouping in R16, that is, for multiple communication devices belonging to the same PO, different WUS sequences are used to correspond to different communication device groups (UE groups) on the same time-frequency resources. For example, assuming that 100 communication devices (numbered 0-99) belong to the same PO, these 100 communication devices are divided into 4 groups. For example, communication devices 0-24 belong to group 0, communication devices 25-49 belong to group 1, communication devices 50-74 belong to group 2, and communication devices 75-99 belong to group 3. There are four WUS sequences. If the network device wants to wake up communication device No. 0, it will send the WUS sequence corresponding to group 0 before the PO. Communication devices No. 0-24 in group 0 all monitor the WUS sequence and are all awakened. However, the 75 communication devices in groups 1, 2 and 3 will not be awakened because they only monitor the WUS corresponding to the group to which they belong. This WUS sequence can also be called a group WUS sequence (group WUS sequence).

[0007] In addition, R16 stipulates that a network device can configure at most two group WUS resources (groupWUS resource) for the same gap, namely a new WUS resource (new WUS resource) and an existing WUS resource (legacy WUS resource), and the new WUS resource is in front of the legacy WUS resource, such as Figure 5 When monitoring a pre-PO WUS, a communication device will only monitor one Group WUS resource. The total number of groups that communication devices can group within each Group WUS resource is configurable. For example, a network device can configure the total number of groups separately for new and existing WUS resources within the same gap. R16 stipulates that the total number of groups within each Group WUS resource must be less than or equal to 8.

[0008] The communication device determines the corresponding group based on the group it is in. Each group has a corresponding group ID, which is usually an integer greater than or equal to 0. R16 also specifies the WUS corresponding to each group, which needs to be associated with a WUS sequence index. In some possible situations, the total number of group IDs may exceed the total number of WUS sequence indices. In this case, it is impossible to directly associate the group ID of the communication device with the WUS sequence index one-to-one, and it is also impossible to associate the grouping of the communication device with the WUS sequence. Therefore, it is urgent to associate the grouping of the communication device with the WUS sequence. Summary of the Invention

[0106] For example, if a network device is configured with one existing WUS resource and two new WUS resources (a first new WUS resource and a second new WUS resource), N_legacy is used to configure the total number of packets configured on the existing WUS resource; N_new is used to configure the total number of packets configured on the two new WUS resources, i.e., the total number of packets configured on the first new WUS resource is N_new, and the total number of packets configured on the second new WUS resource is N_new. In this case, the network device only needs to notify the communication device of two values ​​(N_legacy and N_new) to configure the total number of packets for the three WUS resources (the existing WUS resource, the first new WUS resource, and the second new WUS resource).

[0107] If the network device only configures one or more new WUS resources, one total number of packets (N_new) may be used to configure all new WUS resources to save signaling overhead.

[0129] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0130] The terms "first," "second," and the like in the description, embodiments, claims, and drawings of this application are used solely for descriptive purposes and are not to be construed as indicating or implying relative importance or order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions, such as, for example, inclusion of a series of steps or units. A method, system, product, or apparatus is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0131] It should be understood that in this application, "at least one (item)" means one or more, and "plurality" means two or more. "And / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0132] Figure 4This is a topological diagram of a communication system to which the wake-up signal sequence sending method in the embodiment of the present application is applicable, such as Figure 4 As shown, the communication system, such as long term evolution (LTE), may include a base station and user equipment (UE) 1-6, where UE1-UE6 sends first information to the base station. In addition, UE4-UE6 may also form a communication system, in which the base station may send downlink information to UE1, UE2, UE3, and UE5, and UE5 may also send downlink information to UE4 and UE6.

[0133] It should be noted that the method for generating the wake-up signal sequence provided in the present application is not only applicable to the above-mentioned LTE system, but also to other communication systems, such as 5G NR (new radio) system, global system for mobile communication (GSM), universal mobile telecommunications system (UMTS), code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) system, narrowband Internet of Things (NB-IoT) system, enhanced machine-type communication (eMTC) system and other communication systems. As long as the network device in the communication system needs to send transmission direction indication information, the communication device needs to receive the indication information, and determine the transmission direction within a certain period of time according to the indication information, the method for generating the wake-up signal sequence provided in the present application can be used.

[0134] The network device can be used to convert received air frames into and out of Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, which may include an IP network. The network device can also coordinate attribute management of the air interface. Exemplarily, the network device can be a base transceiver station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, or an evolved Node B (eNB or e-NodeB) in LTE, and this application does not impose specific limitations on this.

[0135] The above-mentioned communication devices can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connection capabilities, or other processing devices connected to wireless modems. The communication devices can communicate with one or more core networks via a radio access network (RAN). The communication devices can be mobile terminals, such as mobile phones (also called "cellular" phones) and computers with mobile terminals. They can also be portable, pocket-sized, handheld, computer-built-in, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. A communication device may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, or user equipment (UE).

[0136] The following describes the embodiments of the present application in conjunction with the accompanying drawings. Figure 5 , Figure 5This is a schematic diagram of the relationship between group wake-up signal resources in an embodiment of the present application. Taking the narrowband internet of things (NB-IoT) as an example, R16 stipulates that network equipment can configure up to two group WUS resources (group WUS resource) for the same gap, namely a new WUS resource (new WUS resource) and an existing WUS resource (legacy WUS resource). The legacy WUSresource is the time-frequency position of the WUS specified in R15, and the new WUS resource refers to a resource (resource) that is different from the time and / or frequency position of the legacy WUS resource. In NB-IoT, the new WUS resource is in front of the legacy WUS resource in terms of time position. In R16, the total number of groups (groups) on the new WUS resource and the legacy WUS resource (i.e., the total number of groups) is configurable. Below, N_new is used to represent the total number of groups on the new WUSresource; N_legacy is used to represent the total number of groups on the legacy WUS resource. R16 stipulates that the total number of groups on each WUS resource is less than or equal to 8, that is, N_new<=8, N_legacy<=8. For example, Table 1 shows the correspondence between WUS resources, the total number of groups in the WUS resources, and group IDs in the WUS resources.

[0137] Table 1

[0138]

[0139] The R16 standard stipulates that the group WUS sequence is composed of the existing WUS (legacy WUS) sequence and phase shift. Specifically, the method for determining the group WUS sequence is as follows:

[0140] Wgroup(m')=W(m')exp(j2πgm / G);

[0141] Where Wgrouop(m') is the group WUS sequence, W(m') is the existing WUS sequence, different groups of WUS resources correspond to different W(m'), exp(j2πgm / G) is the phase shift, G = 132. The variable "g" in "exp(j2πgm / G)" has the following relationship with another variable "x":

[0142] g=14*(x+1), 0≤x≤7;

[0143] In the R16 standard, "x" is also called "WUS sequence index".

[0144] As can be seen from the above description, each group corresponds to a unique group WUS sequence and a unique group ID. The group ID is unique within the same WUS resource, and the total number of groups that can be configured on each WUS resource is less than or equal to 8. In one case, before the current gap, when two WUS resources are configured (new WUS resource and legacyWUS resource), the maximum total number of groups is 8 + 8 = 16, and the corresponding group IDs are {0, 1, 2, ..., 14, 15}. The variable "x" in the group WUS sequence is {0, 1, 2, 3, 4, 5, 6, 7}, a total of 8. Within the same WUS resource, the variable "x" corresponding to each group is unique. Therefore, a mapping method is needed to achieve the mapping from the group ID to the variable "x" to indicate that each group is mapped to the variable "x". It should be noted that this is only an exemplary scenario. In enhanced machine-type communication (eMTC), before any gap, in addition to configuring a maximum of two WUS resources in the time domain, two WUS resources can also be configured simultaneously in the frequency domain. In this case, the maximum total number of groups is 4*8=32. Therefore, it is necessary to implement a mapping of a maximum of 32 group identifiers to the variable "x".

[0145] Specifically, Figure 6 FIG. 1 is a flow chart of a method for sending a wake-up signal sequence in an embodiment of the present application. Figure 6 As shown, the method of this embodiment can be executed by a network device, and the method for sending a wake-up signal sequence may include:

[0146] 601. Determine a group identifier of a first group.

[0147] In this embodiment, the first group is the group to which the communication device belongs. For example, Table 2 shows the corresponding relationship between the group identifier, WUS resources, and the total number of groups.

[0148] Table 2

[0149] Group ID WUS Resources Total number of groups (N) {4,5,6,7,8,9,10,11} new WUS resource 8 {0,1,2,3} legacy WUS resource 4

[0150] N represents the total number of groups on the current group WUS resource. Groups identified by group IDs 4-11 are eight communication device groups on the new WUS resource, so the total number of groups on the new WUS resource is eight, or N = N_new = 8. Groups identified by group IDs 0-3 are four communication device groups on the legacy WUS resource, so the total number of groups on the legacy WUS resource is four, or N = N_legacy = 4.

[0151] 602. Determine the total number of groups configured on the first WUS resource.

[0152] The first wake-up signal WUS resource is a resource for the communication device to receive WUS.

[0153] In an optional implementation, the total number of groups configured on the first WUS resource is directly determined. For example, in Table 2, the total number of groups of communication devices on the first WUS resource (new WUS resource or legacy WUS resource) is 8 or 4.

[0154] In another optional implementation, when the network device does not configure a common WUS (common WUS) in the first WUS resource (the common WUS may also be referred to as a common WUS sequence), the network device may determine the total number of packets configured on the first WUS resource by obtaining the total number of WUS sequences configured on the first WUS resource. For details, please refer to Table 3:

[0155] Table 3

[0156]

[0157] The groups identified by group IDs 4-11 are 8 communication device groups on the new WUS resource, and the WUS sequences of each group are {S4[m], S5[m], S6[m], S7[m], S8[m], S9[m], S10[m], S11[m]}. The groups identified by group IDs 0-3 are 4 communication device groups on the legacy WUS resource, and the WUS sequences of each group are {S0[m], S1[m], S2[m], S3[m]}. Therefore, when the first WUS resource is a new WUS resource, since the total number of WUS sequences configured in the new WUS resource is 8, the total number of groups (N) in the new WUS resource is 8, and the total number of groups in the first WUS resource is 8; when the first WUS resource is a legacy WUS resource, since the total number of WUS sequences configured in the legacy WUS resource is 4, the total number of groups (N) in the legacy WUS resource is 4, and the total number of groups in the first WUS resource is 4.

[0158] In another optional implementation, when the network device configures a common WUS in the first WUS resource, the common WUS can be used to wake up all packets. Therefore, the total number of packets configured on the first wake-up signal WUS resource is determined based on the total number of WUS sequences and the number of common WUSs. The total number of packets configured on the first wake-up signal WUS resource is calculated as follows:

[0159] N = MC;

[0160] Wherein, N is the total number of groups, M is the total number of WUS sequences, and C is the number of common WUSs.

[0161] For details, please refer to Table 4:

[0162] Table 4

[0163]

[0164] Typically, the number of public WUSs is 1, i.e., C = 1. When the first WUS resource is a new WUS resource, the total number of WUS sequences is 9. By using N = MC, the total number of groups (N) can be calculated to be 8. When the first WUS resource is a legacy WUS resource, the total number of WUS sequences is 5. By using N = MC, the total number of groups (N) can be calculated to be 4.

[0165] 603. Generate a WUS sequence for the first group according to the group identifier and the total number of groups.

[0166] The network device can calculate the modulus value based on the group identifier and the total number of packets. The modulus value is the aforementioned variable "x" and satisfies the formula:

[0167] x = g mod N;

[0168] Where x represents the modulus value, g represents the group identifier, N represents the total number of groups, and mod represents the modulo operation.

[0169] The network device generates a WUS sequence of the first packet according to the modulus value.

[0170] For example, Table 5 shows the result of the network device allocating base sequences to 12 communication devices.

[0171] Table 5

[0172]

[0173] Through the above method, the network device can allocate 8 module values ​​(variable "x") to 12 communication devices. In each group of WUS resources, the module value (variable "x") used by each group is different, so that the module value (variable "x") can support more groupings of communication devices.

[0174] 604. Send a first grouped WUS sequence on a first WUS resource.

[0175] Based on the WUS sequence allocation for each communication device group, the network device can send the WUS sequence of the communication device to be awakened to activate the communication device. In this embodiment, "receiving" or "monitoring" (monitor / detect) refers to the action of parsing the WUS sequence from the signal received by the network device.

[0176] In the embodiment of the present application, the WUS sequence is associated with the grouping of the communication devices through a modulo operation, so that the modulo value (variable "x") can support the grouping of more communication devices.

[0177] Relative to Figure 6 In the embodiment shown, this application proposes a method for receiving a wake-up signal sequence. For details, please refer to Figure 7 , Figure 7 FIG. 1 is a flow chart of a method for receiving a wake-up signal sequence in an embodiment of the present application. Figure 7 As shown, the method of this embodiment can be executed by a communication device, and the wake-up signal sequence receiving method may include:

[0178] 701. Obtain a group identifier of a first group.

[0179] In this embodiment, the communication device may calculate the group identifier of its own group based on its own identity (ID) and other parameters according to the protocol rules. This group is referred to as the first group. The protocol rules may be predefined by the user or agreed upon in the standard, and are not limited here.

[0180] In this embodiment, the group identifier of the first group is similar to the group identifier of the first group in the aforementioned step 601, and is not described again here.

[0181] 702. Obtain the total number of groups configured on the first WUS resource.

[0182] In this embodiment, the first WUS resource is a resource for the communication device to receive WUS.

[0183] In an optional implementation, the communication device receives a signaling or parameter sent by the network device to obtain the total number of packets configured on the first WUS resource sent by the network device. The signaling or parameter may be unicast sent by the network device to the communication device or broadcast sent by the network device to all communication devices in the corresponding cell, which is not limited herein.

[0184] In another optional implementation, when the network device does not configure a common WUS in the first WUS resource, the network device notifies the communication device that no common WUS is configured on the first WUS resource. Therefore, the communication device can determine the total number of groups configured on the first WUS resource by obtaining the total number of WUS sequences configured on the first WUS resource. In this case, the total number of WUS sequences is equal to the total number of groups. The total number of WUS sequences can also be obtained by the communication device by receiving a signaling or parameter sent by the network device.

[0185] In another optional implementation, when the network device configures a public WUS in the first WUS resource, the public WUS can be used to wake up all packets, and the network device notifies the communication device that the public WUS is configured on the first WUS resource. Therefore, the communication device can determine the total number of packets configured on the first wake-up signal WUS resource based on the total number of WUS sequences and the number of public WUSs. The total number of packets configured on the first wake-up signal WUS resource is calculated as follows:

[0186] N = MC;

[0187] Wherein, N is the total number of groups, M is the total number of WUS sequences, and C is the number of common WUSs.

[0188] In this embodiment, the total number of groups, the total number of WUS sequences, and the common WUS are similar to those in the aforementioned step 602 and are not described again here.

[0189] 703. Generate a WUS sequence for the first group according to the group identifier and the total number of groups.

[0190] In this embodiment, the communication device may calculate a modulus value based on the group identifier and the total number of packets. The modulus value is the aforementioned variable "x" and satisfies the formula:

[0191] x = g mod N;

[0192] Where x represents the modulus value, g represents the group identifier, N represents the total number of groups, and mod represents the modulo operation.

[0193] The communication device generates a WUS sequence of the first packet according to the modulus value.

[0194] 704. Receive a first grouped WUS sequence on a first WUS resource.

[0195] In this embodiment, the communication device wakes up at a time point corresponding to a fixed WUS resource according to the configuration of the network device, and monitors whether a corresponding WUS sequence is received.

[0196] In the embodiment of the present application, the WUS sequence is associated with the grouping of the communication devices through a modulo operation, so that the modulo value (variable "x") can support the grouping of more communication devices.

[0197] This application also proposes a method for sending a wake-up signal sequence. Figure 8 Specifically, Figure 8 FIG. 1 is a flow chart of another method for sending a wake-up signal sequence in an embodiment of the present application. Figure 8 As shown, the method of this embodiment can be executed by a network device, and the method for sending a wake-up signal sequence may include:

[0198] 801. Determine the total number of groups configured on the first WUS resource.

[0199] In this embodiment, it is similar to the aforementioned step 602 and will not be repeated here.

[0200] 802. Determine whether to send first indication information according to the total number of packets, where the first indication information is used to indicate whether a public WUS is configured on the first WUS resource.

[0201] In this embodiment, the first indication information is used to indicate whether a public WUS is configured on the first WUS resource (i.e., whether the public WUS corresponding to the first WUS resource is sent). For example, when the first indication information is "0", the public WUS is not sent; when the first indication information is "1", the public WUS is sent.

[0202] When the network device determines that the total number of packets configured on the first WUS resource is 1, it is known that there is only one packet on the first WUS resource, and therefore, no public WUS needs to be configured. In this case, the first indication information may be determined not to be sent based on the total number of packets.

[0203] In an embodiment of the present application, when the network device configures only one group in the first WUS resource, the network device does not need to configure a public WUS in the first WUS resource, and thus does not need to send the first indication information, thereby saving network resource overhead.

[0204] Relative to Figure 8 In the embodiment shown, this application proposes another method for receiving a wake-up signal sequence. For details, please refer to Figure 9 , Figure 9 FIG. 1 is a flow chart of another method for receiving a wake-up signal sequence according to an embodiment of the present application. Figure 9 As shown, the method of this embodiment can be executed by a communication device, and the wake-up signal sequence receiving method may include:

[0205] 901. Obtain the total number of groups configured on the first WUS resource.

[0206] In this embodiment, the first WUS resource is a resource for the communication device to receive WUS.

[0207] In an optional implementation, the communication device receives a signaling or parameter sent by the network device to obtain the total number of packets configured on the first WUS resource sent by the network device. The signaling or parameter may be unicast sent by the network device to the communication device or broadcast sent by the network device to all communication devices in the corresponding cell, which is not limited herein.

[0208] In another optional implementation, the communication device may determine the total number of groups configured on the first WUS resource by obtaining the total number of WUS sequences configured on the first WUS resource. If the total number of WUS sequences is 1, the total number of groups configured on the first WUS resource is determined. In this case, the total number of WUS sequences is equal to the total number of groups. The total number of WUS sequences may also be obtained by the communication device by receiving a signaling or parameter sent by the network device.

[0209] 902. The total number of packets determines whether to monitor a public WUS on the first WUS resource.

[0210] In this embodiment, if the communication device determines that the total number of packets configured on the first WUS resource is 1, it can be determined that the network device has not configured a public WUS on the first WUS resource. Therefore, the communication device does not need to monitor the public WUS on the first WUS resource and only receives the WUS sequence of the first packet on the first WUS resource. This sequence can also be called a "group-specific WUS."

[0211] When the communication device determines that the total number of packets configured on the first WUS resource is greater than 1, it can be determined that the network device will send first indication information. Therefore, the communication device can monitor the first indication information on the first WUS resource and determine whether to monitor the public WUS based on the first indication information.

[0212] According to the configuration of the network device, the communication device will wake up at the time corresponding to the fixed WUS resource and monitor whether the corresponding WUS sequence is received.

[0213] In an embodiment of the present application, when the communication device determines that the network device has only configured one group in the first WUS resource, the communication device does not need to monitor the public WUS in the first WUS resource, thereby reducing the power consumption of the communication device.
