Through various possible network access, it realizes ubiquitous connection between things and things, and things and people, and realizes intelligent perception, identification, and management of objects and processes.

[0003] In 5G NR IoT scenarios, PDCCH (Physical Downlink Control Channel) coverage may be reduced for the following reasons: The number of receiving antennas in IoT UEs is reduced, resulting in a reduction in the diversity gain of the PDCCH receiving antennas; the efficiency of the IoT UE receiving antennas is reduced, such as due to a reduction in antenna size, which results in a reduction in the gain of the PDCCH receiving antennas; the bandwidth of the IoT UE is reduced, resulting in a reduction in the frequency diversity gain of the PDCCH and a limited aggregation level of the PDCCH. Therefore, PDCCH coverage recovery is required. Summary of the Invention

[0018] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0019] In this application, the term "and / or" simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this document indicates that the related objects are in an "or" relationship.

[0020] The "multiple" appearing in the embodiments of this application refers to two or more. The first, second, etc. descriptions appearing in the embodiments of this application are only for illustration and distinction of the described objects. There is no order, nor does it represent a special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application. The "connection" appearing in the embodiments of this application refers to various connection methods such as direct connection or indirect connection to achieve communication between devices, and the embodiments of this application do not impose any limitation on this.

[0021] The technical solutions of the embodiments of the present application can be applied to Figure 1 The exemplary communication system 100 shown includes a terminal 110 and a network device 120 , wherein the terminal 110 is in communication connection with the network device 120 .

[0022] The example communication system 100 can be, for example: a Global System of Mobilecommunication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, an advanced long term evolution (LTE-A) system, a New Radio (NR) system, an evolution system of the NR system, an LTE system on unlicensed spectrum (LTE-U), an NR system on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U), a Universal Mobile Telecommunication System (UMTS), a next-generation communication system or other communication systems, etc.

[0023] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and vehicle-to-vehicle (V2V) communication, and the embodiments of the present application can also be applied to these communication systems. Optionally, the communication system in the embodiments of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, and a standalone (SA) networking scenario.

[0024] The terminal 110 in the embodiments of the present application may refer to a user device, an access terminal, a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus. The terminal may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a relay device, a vehicle-mounted device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved public land mobile network (PLMN), etc., and the embodiments of the present application are not limited thereto.

[0025] The network device 120 in the embodiment of the present application can be a device for communicating with a terminal. The network device can be an evolved base station (eNB or eNodeB) in an LTE system, or a wireless controller in a cloud radio access network (CRAN) scenario, or the network device can be a relay device, an access point, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), etc. The embodiment of the present application is not limited.

[0026] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services, implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for processing physical layer protocols and real-time services, implementing the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers.

[0027] Generally, a search space set (SST) contains properties such as the PDCCH monitoring timing and search space type. The PDCCH monitoring timing includes the slot-level period and offset, as well as the starting symbol within the slot. A SST is typically bound to a CORESET (Control Resource Set). A CORESET contains properties such as the PDCCH's frequency domain resources and duration (number of symbols). A PDCCH consists of one or more CCEs. For a PDCCH composed of n CCEs, its aggregation level is n. A CCE consists of six REGs, each representing a resource block (RB) within an OFDM symbol. REGs within a CORESET are numbered in ascending order using a time-first order, with number 0 corresponding to the first OFDM symbol and the lowest-numbered resource block in the CORESET. A CORESET is associated with a CCE-to-REG mapping, which can be interleaved or non-interleaved and is described by REG bundles.

[0028] The remaining minimum system information in NR is equivalent to SIB1 in LTE, which includes essential system information in addition to the MIB. RMSI can also be referred to as SIB1. RMSI is carried on the PDSCH, which is scheduled by the PDCCH. The PDSCH carrying RMSI is generally referred to as the RMSI PDSCH, and the PDCCH scheduling the RMSI PDSCH is generally referred to as the RMSI PDCCH.

[0029] The search space set (search space set) in which the RMSI PDCCH resides is generally referred to as the Type 0-PDCCH search space set. Generally, the Type 0-PDCCH search space set can be configured by the MIB or by RRC (in situations such as handover). The Type 0-PDCCH search space set can be configured as search space 0 (or search space set 0). The Type 0-PDCCH search space set can be bound to CORESET 0. In addition to the search space set for the RMSI PDCCH, other common search spaces or common search space sets, such as the search space set for the OSI PDCCH (Type 0A-PDCCH search space set), the search space set for the RAR PDCCH (Type 1-PDCCH search space set), and the search space set for the paging PDCCH (Type 2-PDCCH search space set), can be configured as search space set 0. These other common search spaces or common search space sets can be bound to CORESET 0. Generally, the above common search spaces or common search space sets can be reconfigured.

[0030] The RMSI PDCCH monitoring timing is associated with the synchronization signal block. The UE obtains this association based on the RMSI PDCCH monitoring timing table. During initial access, the UE searches for a synchronization signal block and determines the time domain position (start symbol index or first symbol index) of the RMSI PDCCH associated with the synchronization signal block based on the row index of the table indicated by the PBCH. The UE can then detect the RMSI PDCCH and receive and decode the RMSI PDSCH according to the RMSI PDCCH scheduling.

[0031] In NR, generally, the UE is a UE that supports 100MHz bandwidth. During initial access, the UE blindly detects the PSS / SSS / PBCH in the synchronization signal block and obtains the MIB and time index information carried in the PBCH. The UE obtains the configuration of the CORESET (which can be called CORESET0) and its search space set (which can be called search space set0) that schedules SIB1 through the information in the MIB. Then, the UE can monitor the Type0-PDCCH that schedules the PDSCH carrying SIB1 and decode SIB1. Since the bandwidth of CORESET0 is set through a table in the PBCH, the maximum bandwidth of CORESET0 is implicitly defined in the protocol. Furthermore, the protocol stipulates that the frequency domain resources of the PDSCH carrying SIB1 are within the bandwidth (PRBs) of CORESET0, so the maximum bandwidth of the PDSCH carrying SIB1 is also implicitly defined in the protocol. In fact, in the idle state, the UE operates in the initial active downlink BWP (initial active DL BWP), and the frequency domain position of the initial active downlink BWP is the same as the frequency domain position of CORESET0 by default (non-default, the frequency domain position of the initial active downlink BWP can be modified by signaling to cover the frequency domain position of CORESET0).

[0032] See Figure 2 , Figure 2 A method for confirming a CCE (Control Channel Element) index is provided, which can be executed by a user equipment. Figure 2 As shown, the following steps are included:

[0034] In an optional solution, a specific implementation manner in which the UE determines the index of the PDCCH candidate may include:

[0035] The UE determines the CCE index of the PDCCH candidate based on the total number of CCEs. In other words, the total number of CCEs can be used to calculate the CCE index of the PDCCH candidate.

[0036] In an optional solution, the total number of CCEs may specifically include: the sum of the number of CCEs in one or more control resource sets (CORESETs). The sum may be as follows: for example, if the total number of CCEs includes one CORESET, the total number of CCEs may be the total number of CCEs in the one CORESET. If the total number of CCEs includes multiple CORESETs, the total number of CCEs may be the sum of the total number of CCEs in the multiple CORESETs.

[0037] In one optional solution, the total number of CCEs may specifically include: the sum of the number of CCEs in one or more monitoring opportunities.

[0038] In one optional solution, the total number of CCEs may specifically include: the sum of the number of CCEs in the CORESET at one or more listening opportunities. The sum may specifically be as follows: For example, if the total number of CCEs includes one listening opportunity, the total number of CCEs may be the total number of CCEs in the CORESET at one listening opportunity. If the total number of CCEs includes multiple listening opportunities, the total number of CCEs may be the sum of the total number of CCEs in the CORESET at multiple listening opportunities.

[0039] In one optional solution, the total number of CCEs may specifically include the sum of the number of CCEs in a CORESET in one or more time slots. The sum may be as follows: for example, if the total number of CCEs includes one time slot, the total number of CCEs may be the total number of CCEs in the CORESET in one time slot. If the total number of CCEs includes multiple time slots, the total number of CCEs may be the sum of the total number of CCEs in the CORESET in multiple time slots.

[0042] In another optional solution, the total number of PDCCH candidates is the sum of the number of PDCCH candidates in one or more control resource sets (CORESETs). The above sum may specifically include: if there is only one CORESET, the total number of PDCCH candidates may be the sum of the number of PDCCH candidates in the one CORESET; if the total number of PDCCH candidates includes multiple CORESETs, the total number of CCEs may be the sum of the total number of PDCCH candidates in the multiple CORESETs.

[0043] In another optional solution, the total number of PDCCH candidates is the sum of the number of PDCCH candidates in one or more monitoring opportunities. The above sum may specifically include: if the total number of PDCCH candidates is one monitoring opportunity, the total number of PDCCH candidates may be the sum of the number of PDCCH candidates in the one monitoring opportunity; if the total number of PDCCH candidates includes multiple monitoring opportunities, the total number of CCEs may be the sum of the total number of PDCCH candidates in the multiple monitoring opportunities.

[0044] In another optional solution, the total number of PDCCH candidates is the sum of the number of PDCCH candidates in the CORESET at one or more monitoring occasions. The above sum may specifically include: if there is one monitoring occasion, the total number of PDCCH candidates may be the sum of the number of PDCCH candidates in the CORESET at one monitoring occasion; if the total number of PDCCH candidates includes multiple monitoring occasions, the total number of CCEs may be the sum of the total number of PDCCH candidates in the CORESET at multiple monitoring occasions.

[0045] In another optional solution, the total number of PDCCH candidates is the sum of the number of PDCCH candidates in one or more time slots.
