Description

[0001] This case is a divisional application of Chinese patent application No. 201811142313.5, filed on September 28, 2018. Technical Field

[0002] The embodiments of the present invention relate to, but are not limited to, the field of network communication, and specifically, to, but are not limited to, wake-up signal sending and receiving methods, devices, base stations, terminals, and storage media. Background Technology

[0003] Machine-type communications (MTC), also known as machine-to-machine (M2M), is currently the primary application form of the Internet of Things (IoT). Most MTC devices deployed in the market are based on the Global System for Mobile Communications (GSM). In recent years, due to the high spectrum efficiency of LTE / LTE-A, more and more mobile operators have chosen LTE / LTE-A as the evolution direction for their future broadband wireless communication systems. MTC services based on LTE / LTE-A will also become more attractive.

[0004] The 3rd Generation Partnership Project (3GPP) technical report TR45.820V200 discloses several technologies suitable for Cellular Internet of Things (C-IoT), among which Narrow Band Internet of Things (NB-IoT) technology is the most noteworthy. NB-IoT systems focus on low-complexity and low-throughput radio frequency access technologies. Key research objectives include: improved indoor coverage, support for a massive number of low-throughput user devices, low latency sensitivity, ultra-low device cost, low device power consumption, and network architecture.

[0005] The network can send paging messages to users (UEs) in both idle and connected states. The paging process can be triggered by the core network to notify a UE of a paging request, or by the eNB to notify of system information updates. Paging messages are scheduled using Physical Downlink Control Channel (PDCCH) scrambled with a Radio Network Temporary Identifier (RNTI) and transmitted on the Physical Downlink Shared Channel (PDSCH). At the paging occasion (PO), the terminal checks the corresponding PDCCH to determine if the PDSCH indicated by the PDCCH carries a paging message. If the terminal does not detect the corresponding PDCCH at that PO, it means there is no paging message at that PO, and the terminal enters a sleep state, not receiving data, until the next PO. This is called Discontinuous Reception (DRX). In other words, the terminal needs to perform blind PDCCH detection at every PO, resulting in significant terminal power consumption.

[0006] To reduce terminal power consumption, a wake-up signal (WUS) is introduced. The base station sends a signal before each Product Layout (PO) indicating whether to perform PDCCH detection. The terminal first detects the WUS and determines whether to detect the corresponding PDCCH based on the detection result. When a WUS is detected, the terminal detects the corresponding PDCCH; otherwise, the terminal does not detect the PDCCH. The introduction of the WUS signal reduces the number of times the terminal detects the PDCCH, thus saving terminal power. However, the WUS applies to all terminals within a PO. This means that if one terminal needs to be woken up, the base station will send a WUS, waking up all other terminals within the same PO. These terminals will then all detect the PDCCH, increasing the number of unnecessary PDCCH detections. Summary of the Invention

[0154] Eighth embodiment Specific Implementation Example 1 Example 1 Assume that the group index corresponding to the terminal is determined according to the terminal type, where the terminal type refers to different versions of the terminal; specifically, the group index corresponding to the R15 terminal is 0.

[0155] Example 2 Assume that the group index corresponding to the terminal is determined based on the terminal type and terminal capabilities, where terminal capabilities refer to whether the terminal supports packet WUS. For R15 terminals and R16 terminals that do not support Packet WUS, the group index is 0.

[0156] Example 3 Assume the group index corresponding to a terminal is determined based on the terminal identifier and terminal capabilities, where terminal capabilities refer to whether the terminal supports packet WUS; the group index corresponding to the following two types of terminals is 0: R16 does not support terminals that support Packet WUS; R16 supports a subset of terminals in the WUS group. Preferably, terminals whose terminal identifiers are less than a threshold A, and terminals whose terminal identifiers are equal to C after modulo B, where A, B, and C are preset positive integers greater than 0, or calculated based on a configured scaling factor. For example, assuming the configured scaling factor is 10%, then the value of A is 10% * the maximum terminal identifier value, rounded down.

[0157] Example 4 Assume that the group index corresponding to a terminal is determined based on the terminal type, terminal identifier, and terminal capabilities, where terminal capabilities refer to whether the terminal supports packet WUS; the group index corresponding to the following three types of terminals is 0: R15 terminal; R16 does not support terminals that support Packet WUS; R16 supports a subset of terminals in the WUS group. Preferably, terminals whose terminal identifiers are less than a threshold A, terminals whose terminal identifiers are equal to C when modulo B, or terminals whose terminal identifiers are preset positive integers greater than 0, or terminals whose terminal identifiers are calculated based on a configured scaling factor.

[0158] Example 5 Assume that the group index corresponding to the terminal is determined based on the terminal capabilities, the number of groups, and the terminal identifier; For terminals that do not support Packet WUS in R16, the group index is 0; for terminals that support Packet WUS in R16, the group index is obtained by taking the terminal identifier modulo the number of groups + D, where D is a positive integer greater than 0.

[0159] Example 6 Assume the group index corresponding to the terminal is determined based on the configured resources, number of groups, terminal capabilities, and terminal identifier. For terminals in R16 that do not support Packet WUS, the group index is 0. For terminals in R16 that support Packet WUS, the second group number at the resource location is determined based on the number of groups and the configured resources. Assuming the number of groups is 4 (the number of groups on the PO), and assuming two time-domain resource locations are configured, then the second group number is 2. The group index is obtained by taking the modulo of the second group number and adding D based on the terminal identifier.

[0160] In the example above, the WUS corresponding to group index 0 is R15 WUS. It is assumed that the group index corresponding to R15 WUS is 0; of course, the group index can also be other fixed values.
