[0040] In order to facilitate the understanding of those skilled in the art, the embodiments of the present disclosure enumerate several embodiments to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the several embodiments provided by the embodiments of the present disclosure can be implemented alone, can be implemented in combination with the methods of other embodiments in the embodiments of the present disclosure, and can be implemented alone or in combination with some methods in other related technologies, and the embodiments of the present disclosure are not limited thereto.
[0041] In order to better understand the technical solution described in any embodiment of the present disclosure, application scenarios of the related technology will be described first.
[0042] In order to support Internet of Things services in the fourth generation mobile communication technology (4G system), two technologies have been proposed: Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT).
[0043] These two technologies are mainly targeted at scenes with low speed and high latency. For example, meter reading, environmental monitoring, etc. In one embodiment, NB-IoT can only support a maximum speed of several hundred k, and MTC can only support a maximum speed of several M. However, with the development of Internet of Things services, such as the popularization of services such as video surveillance, smart home, wearable devices, and industrial sensing monitoring, these services usually require speeds of several tens to hundreds of M, and at the same time, there are relatively high requirements for latency, and MTC and NB-IoT technologies in the fourth generation mobile communication technology are difficult to meet the requirements. Based on this situation, it has been proposed to redesign a new terminal type to cover the requirements of the Internet of Things of such terminals in the new radio of the fifth generation mobile communication technology 5G.
[0044] In one embodiment, such a new terminal type is called a reduced capability terminal (RedCap, Reduced capability UE) or abbreviated as NR-lite. RedCap based on 5G NR-lite usually needs to meet the requirements of low cost, low complexity, some coverage extension, and power saving.
[0045] Since 5G new radio was designed for high-end terminals such as high speed and low latency, the related design cannot meet the above requirements of NR-lite. In order to meet the requirements of NR-lite, it is necessary to modify the new radio (NR, New Radio) system. In one embodiment, in order to meet the requirements of low cost, low complexity, etc., the radio frequency bandwidth of NR-IoT can be limited, for example, the radio frequency bandwidth can be limited to 20 MHz. In one embodiment, the size of the buffer of NR-lite can be limited, and further, the size of the transport block received each time can be limited, etc. In one embodiment, the possible optimized direction for power saving is to simplify the communication flow and reduce the number of times that NR-lite users detect the downlink control channel, etc.
[0046] In one embodiment, the information element (IE) field PDCCH-ConfigCommon is used to configure cell-specific Physical Downlink Control Channel (PDCCH) parameters provided in the system information block (SIB) and in dedicated signaling.
[0047] In one embodiment, commonControlResourceSet is an additional common control resource set that can be configured and used in the search space of any common or unique terminal. If the network configures this field, it uses a ControlResourceSetId other than 0 for this ControlResourceSet. The network configures commonControlResourceSet in SIB1 to be included in the bandwidth of control resource set (CORESET) #0.
[0048] In one embodiment, the parameters of the common CORESET#0 can be used for the search space of any common or unique terminal.
[0049] After the Redcap terminal is introduced, a downlink initial BWP for Random Access Response (RAR) can be set individually for the Redcap terminal in SIB1. This initial BWP may be the initial BWP used for paging. The method of setting the common search space in the initial BWP is not defined.
[0050] As shown in FIG. 2, in this embodiment, a resource configuration method is provided, which is performed by an access network device, and includes the following step 21.
[0051] In step 21, the physical downlink control channel (PDCCH) common configuration information configured for the initial bandwidth portion (BWP) is transmitted to the first type terminal.
[0052] The downlink control channel common configuration information is used to indicate a predetermined resource for a first type terminal to perform a predetermined operation, and the predetermined resource includes: An additional common control resource set (CORESET); an additional common search space; Common control resource set (CORESET) 0, A common search space 0.

The first type terminal and the second type terminal are different types of terminals. In one embodiment, the first type terminal may be a Redcap terminal, and the second type terminal may be a non-Redcap terminal other than the Redcap terminal.
[0054] The access network device according to the present disclosure may be a base station, where the base station may be of various types, for example, a base station of a fifth generation mobile communication (5G) network, or other evolved base station.
[0055] In one embodiment, a downlink initial BWP is configured in a first type terminal, and PDCCH common setting information configured for the initial BWP is transmitted to the first type terminal, where the downlink control channel common setting information is used to indicate predetermined resources for the first type terminal to perform a predetermined operation, and the predetermined resources include at least one of an additional common control resource set (CORESET), an additional common search space, a common control resource set (CORESET) 0, and a common search space 0.
[0056] In addition, the PDCCH common configuration information may be included in a PDCCH common configuration (PDCCH-configCommon) field or a PDCCH common system information block configuration (PDCCH-configCommonSIB) field of a RedCap-specific initial downlink BWP configuration (RedCap-specific initial DL BWP configuration).
[0057] In addition, information such as frequency domain resource information of PDCCH and the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols occupied by the time domain is encapsulated in CORESET, and information such as the PDCCH start OFDM symbol, monitoring period, and related CORESET is encapsulated in the search space. The common search space is mainly used at the time of access and cell switching, and is used for monitoring control information related to, for example, a broadcast control channel (BCCH), paging, RAR, etc. Related messages such as RAR, i.e., messages for random access response, include msg2, msg4, msgB, etc.

[0065] In addition, the CORESET associated with all the search spaces here can be understood as a CORESET associated with a search space required to perform all the predetermined operations by the terminal, and all the predetermined operations can include, but are not limited to, a random access response (RAR) monitoring operation, a paging monitoring operation, a system message monitoring operation, and the like.

[0079] Note that CORESET0 and search space 0 can be set in the Master Information Block (MIB), and other CORESETs and / or search spaces other than 0 must be set in SIB1. For example, CORESET1 and / or search space 1 are set in SIB1.
[0080] In one embodiment, the predetermined resources further include resources configured for the second type terminal in the predetermined message, the predetermined message including at least one of an MIB and an SIB1, the resources configured for the second type terminal including at least one of a resource for paging monitoring, a resource for monitoring a system message, and a resource for RAR monitoring, and the resources configured for the second type terminal are configured as a common search space for performing a predetermined operation by the first type terminal.
[0081] In one embodiment, CORESET0 and / or search space 0 are set for the second type of terminal in the MIB, and an additional CORESETx and / or additional search space CORESETx are set for the second type of terminal in the SIB1, where x may be 1, 2, etc. instead of 0.
[0082] In one embodiment, for monitoring SIB1, CORESET0 and / or search space 0 are configured for the second type terminal in the MIB, and CORESETx and / or search space CORESETx are configured for the second type terminal in SIB1, where x is not 0 but may be 1, 2, etc. Monitoring of Other SI, or paging monitoring, or RAR monitoring may be associated with CORESET0 and / or search space 0, or CORESETx and / or search space CORESETx configured for the second type terminal in the MIB, i.e., the settings for COREST and search space may be associated with the settings of CORESET0 and / or search space 0 or additional CORESET and / or additional search space configured in the MIB.
[0083] In one embodiment, a CORESET associated with a search space for paging monitoring configured for a second type terminal is set as a CORESET associated with a search space for paging monitoring of a first type terminal.
[0084] In one embodiment, a CORESET associated with a search space for monitoring system messages configured for a second type of terminal is set as a CORESET associated with a search space for monitoring system messages of a first type of terminal.
[0085] In one embodiment, a search space for paging monitoring configured for a second type terminal is set as a search space for paging monitoring of a first type terminal.
[0086] In one embodiment, a search space for monitoring system messages configured for a second type terminal is set as a search space for monitoring system messages of a first type terminal.
[0087] In one embodiment, an additional common CORESET configured for the second type terminal is configured as a CORESET associated with a search space for RAR monitoring of the first type terminal.
[0088] In one embodiment, the common control resource set (CORESET) 0 is configured as a CORESET associated with a search space for RAR monitoring of the first type terminal.
[0089] In one embodiment, an additional common search space configured for terminals of the second type is configured as a search space for RAR monitoring of terminals of the first type.
[0090] In one embodiment, the common search space 0 is set as a search space for RAR monitoring of the first type terminals.
[0091] In one embodiment, an additional common CORESET or CORESE0 associated with the RAR search space configured for the second type terminal may be determined as a CORESET associated with the search space for the RAR monitoring of the first type terminal, i.e., both are reused. However, a different search space may be separately configured for the RAR monitoring of the first type terminal. In this case, the network schedules random access response messages of different types of terminals in different search spaces.
[0092] In one embodiment, if the initial BWP configured for the second type terminal does not include CORESET0, it means that it does not overlap in bandwidth with the initial BWP of the first type terminal, in which case the RAR search space configured for the second type terminal needs to configure an additional common CORESET separately, for example, an additional common CORESET such as commonControlResourceSet-Redcap or an additional common CORESET2 different from the common CORESET ID added in the bandwidth of the initial BWP of the first type terminal. In this case, the network schedules the random access response messages of different types of terminals with different initial BWPs.
[0093] In one embodiment, in the PDCCH-ConfigCommon field, the commonControlResourceSet needs to be extended for the first type terminal to set one added (or additional) common CORESET, and the ID of this added common CORESET may be the same as or different from the additional CORESET included in the initial BWP set for the second type terminal. For example, in the PDCCH-ConfigCommon field, the commonControlResourceSet needs to be extended for the first type terminal to set one added common CORESET#2 or common CORESET-Redcap for RAR monitoring, while monitoring of paging messages, system messages, etc. set for the first type terminal can continue to use one added common CORESET, such as added CORESET#1 or CORSET0 set for the second type terminal, thereby avoiding confusion.
[0094] In one embodiment, the commonControlResourceSet in the PDCCH-ConfigCommon field configured for the second type terminal is used to configure one additional common CORESET#1 for RAR monitoring, and monitoring of paging messages, system messages, etc. configured for the first type terminal can continue to use one common CORESET0 configured for the second type terminal (if the second type terminal does not use the additional CORESET), so no confusion occurs.
[0095] In one embodiment, if the initial BWP configured for the second type terminal includes CORESET0, it means that there is an overlap in bandwidth with the initial BWP of the first type terminal, and in this case, the commonControlResourceSet in the PDCCH-ConfigCommon field configured for the second type terminal must be included in CORESET0. As a preferred embodiment, it may be completely the same as the configuration of the second type terminal. The system message monitoring and paging message monitoring can completely reuse the configuration of the second type terminal, and the RAR message monitoring can also completely reuse the configuration of the second type terminal, or the RAR search space can be configured separately with an additional common CORESET, for example, commonControlResourceSet-Redcap or common CORESET1.
[0096] In an embodiment of the present disclosure, downlink control channel common setting information set for the initial bandwidth portion (BWP) is sent to the first type terminal, and the downlink control channel common setting information is used to indicate a predetermined resource for the first type terminal to perform a predetermined operation, and the predetermined resource includes at least one of an additional common control resource set (CORESET), an additional common search space, a common control resource set (CORESET) 0, and a common search space 0. In this way, after receiving the downlink control channel common setting information set for the initial bandwidth portion (BWP) sent from the access network device, the first type terminal can perform a predetermined operation based on the predetermined resource indicated by the downlink control channel common setting information, and compared with a method in which downlink control channel common setting information is not set for the initial BWP, the first type terminal can efficiently and reliably use the BWP resource.

For example, in the PDCCH-ConfigCommon field, the commonControlResourceSet needs to be extended for the first type terminal to set one added common CORESET#2 or common CORESET-Redcap for RAR monitoring, while monitoring of paging messages, system messages, etc. set for the first type terminal can continue to use one added common CORESET, such as added CORESET#1 or CORSET0 set for the second type terminal, thereby avoiding confusion.
[0163] In one embodiment, the commonControlResourceSet in the PDCCH-ConfigCommon field configured for the second type terminal is used to configure one additional common CORESET#1 for RAR monitoring, and monitoring of paging messages, system messages, etc. configured for the first type terminal can continue to use one common CORESET0 configured for the second type terminal (if the second type terminal does not use the additional CORESET), so no confusion occurs.
[0164] In one embodiment, if the initial BWP configured for the second type terminal includes CORESET0, it means that there is an overlap in bandwidth with the initial BWP of the first type terminal, and in this case, the commonControlResourceSet in the PDCCH-ConfigCommon field configured for the second type terminal must be included in CORESET0. As a preferred embodiment, it may be completely the same as the configuration of the second type terminal. The monitoring of the system message and the monitoring of the paging message can completely reuse the configuration of the second type terminal, and the monitoring of the RAR message can also completely reuse the configuration of the second type terminal, or the RAR search space can be configured separately with an additional common CORESET, for example, commonControlResourceSet-Redcap or common CORESET1.
