The wireless communication system may employ different communication techniques such as code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency-Division Multiple Access, OFDMA), single Carrier frequency division multiple access (SC-FDMA), carrier sense multiple access/collision avoidance (Carrier Sense Multiple Access with Collision Avoidance). Networks may be classified into 2G (english: generation) networks, 3G networks, 4G networks, or future evolution networks, such as a fifth Generation wireless communication system (The 5th Generation Wireless Communication System,5G) network, and 5G networks may also be referred to as New Radio (NR) networks, according to factors such as capacity, rate, delay, etc. of different networks. For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved Node B (eNB), a home base station, an Access Point (AP) in a wireless fidelity (Wireless Fidelity, WIFI) system, a wireless relay Node, a wireless backhaul Node, a transmission Point (Transmission Point, TP), or a transmission receiving Point (transmission and receiving Point, TRP), etc., or may be a gNB in an NR system, or may also be a component or a part of a device that forms a base station, etc. In the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device configuration adopted by the network device are not limited.

Further, a Terminal referred to in the present disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like, and may be a device that provides voice and/or data connectivity to a User, for example, a handheld device, an in-vehicle device, or the like that has a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a palm top computer, a personal digital assistant (Personal Digital Assistant, PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, in the case of a vehicle networking (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure are not limited to the specific technology and specific device configuration adopted by the terminal.

In the embodiment of the disclosure, any feasible wireless communication technology can be adopted by the network device and the terminal to realize mutual data transmission. The transmission channel corresponding to the network device sending data or control information to the terminal is called a Downlink (DL), and the transmission channel corresponding to the terminal sending data or control information to the network device is called an Uplink (UL). It is to be appreciated that the network devices involved in embodiments of the present disclosure may be base stations. Of course, the network device may be any other possible network device, and the terminal may be any possible terminal, which is not limited by the present disclosure.

In a New Radio (NR) system, when a terminal needs to transmit a channel/signal, the channel/signal is transmitted through a control resource set (Control Resource Set, core).

It is to be understood that the transmission channel according to the present disclosure may be understood as a data path formed by transmitting corresponding data on corresponding time domain and frequency domain resources, that is, the above-mentioned channel. For example, the network device transmits the downlink control information on the corresponding time domain and frequency domain resources, thereby forming a data path for transmitting the downlink control information. The data path is a physical downlink control channel (Physical Downlink Control Channel, PDCCH). Transmitting the downlink control information may also be interpreted as transmitting the PDCCH.

The control resource set includes a plurality of control resource set types, and different control resource set types can be used to transmit different xi channels/signals. Wherein control resource set 0 is used for transmitting a physical downlink control channel (Physical Downlink Control Channel, PDCCH).

The frequency domain resources occupied by the control resource set 0 are indicated by a master information block (Master Information Block, MIB). As shown in table 1, MIB includes the following information fields:

TABLE 1

As shown in table 1 above, the frequency domain resources of control resource set 0 are determined based primarily on PDCCH-ConfigSIB1 information domain indication. The PDCCH-ConfigSIB1 information field indicates the number of resources in the control resource set 0, the number of occupied OFDM symbols, and an Offset (Offset) corresponding to the first synchronization signal (Primary Synchronization Signal, PSS)/the second synchronization signal (Secondary Synchronization Signal, SSS), as shown in table 2 below.

TABLE 2

Wherein the number of resources represents the number of frequency domain resources allocated to the control resource set 0 by the network device, the number of symbols represents the number of time domain resources (OFDM symbols) allocated to the control resource set 0 by the network device, the Offset represents an Offset (Offset) between the frequency domain resources corresponding to the current control resource set and the first synchronization signal (Primary Synchronization Signal, PSS)/second synchronization signal (Secondary Synchronization Signal, SSS), and the frequency domain position of the control resource set can be determined based on the Offset.

Currently, it is considered that the NR technology is supported by a frequency band having a small system bandwidth supported by a terminal, and these frequency bands mainly serve dedicated services such as dedicated communication, public protection, disaster relief, and the like of power systems/railway systems in some countries and regions, for example, frequency bands having frequency band numbers n8, n26, n28, and n 100. In general, the system bandwidths supported by n8, n26 and n28 are 3MHz, and the system bandwidth supported by n100 is 2.8 MHz-3.6 MHz. Because of the small system bandwidth supported by the system, the number of available PRBs on the frequency bands is about 15, but the number of PRBs with the smallest configuration of the control resource set 0 in the related technology is 24, and in this case, the bandwidth of the control resource set 0 configured by the network device is larger than the system bandwidth.

Therefore, when the terminal performs the transmission processing of the PDCCH, it cannot know which resources in the control resource set 0 can be used for transmitting the PDCCH, and further cannot accurately receive the PDCCH.

Based on the above, the embodiment of the disclosure provides a resource determining method, which determines an available resource of a control resource set based on indication information sent by a network device, where the available resource of the control resource set is a transmission resource capable of transmitting a PDCCH, so that a terminal can receive the PDCCH based on the available resource of the control resource set, and improve transmission reliability of the PDCCH.

Fig. 2 is a flowchart illustrating a resource determination method, as shown in fig. 2, performed by a terminal according to an exemplary embodiment, including the following steps.

In step S11, indication information sent by the network device is received, where the indication information is used to indicate available resources of the control resource set.

In one embodiment, the control resource set is control resource set 0.

Wherein the available resources are transmission resources that can be used for transmitting the PDCCH. This is because the bandwidth allocated to the control resource set by the network device is greater than the system bandwidth, and the resources allocated to the control resource set by the network device cannot be all carried in the system bandwidth, and only part of the resources allocated to the control resource set by the network device are in the system bandwidth, that is, the resources capable of actually transmitting channels/signals. Resources outside the system bandwidth are not available for channel/signal transmission.

For example, the number of resources capable of being transmitted in the system bandwidth is 15, the number of resources configured by the network device for the control resource set is 24, the number of resources of the control resource set is greater than the number of resources capable of being transmitted in the system bandwidth, and it is required to determine which part of the 24 resources corresponding to the control resource set is located in the system bandwidth.

In some embodiments, in case that the bandwidth of the control resource set configured by the network device is greater than the system bandwidth, the terminal can determine available resources of the control resource set based on the indication information and transmit the PDCCH based on the available resources of the control resource set.

In some embodiments, the available resources of the control resource set are actual available PRB resources of the control resource set.

In the embodiment of the disclosure, the available resources of the control resource set are determined based on the indication information sent by the network device, and the available resources of the control resource set are transmission resources capable of transmitting the PDCCH, so that the terminal can receive the PDCCH based on the available resources of the control resource set, and the transmission reliability of the PDCCH is improved.

In a method for determining resources provided in an embodiment of the present disclosure, indication information is carried in MIB.

In some embodiments, the terminal determines available resources of the control resource set based on the MIB, as shown in fig. 3, comprising the steps of:

In step S21, MIB transmitted by the network device is received.

In step S22, available resources of the control resource set are determined based on the MIB.

In the embodiment of the disclosure, the available resources of the control resource set are determined based on the MIB sent by the network equipment, so that the PDCCH is received based on the available resources of the control resource set, and the transmission reliability of the PDCCH is improved.

In a method for determining resources provided in an embodiment of the present disclosure, indication information is carried in a spare bit (spare) information field of a MIB.

Wherein the spark information field corresponds to 1 bit, and the indication information indicates available resources of the control resource set based on 1 bit.

For example, when the value of the spark information field is the first value, the indication information is used for indicating that the available resource of the control resource set is the first available resource; when the value of the spark information field is the second value, the indication information is used for indicating that the available resource of the control resource set is the second available resource. As shown in table 3 below.

TABLE 3 Table 3

In the embodiment of the disclosure, the indication information is carried in the spark information field of the MIB, and the available resources of the control resource set are determined based on the spark information field of the MIB, so that the terminal can receive the PDCCH based on the available resources of the control resource set, and the transmission reliability of the PDCCH is improved.

In one method for determining resources provided in the embodiments of the present disclosure, indication information is carried in a sub-carrier interval sub-carrier spacing common information field of a main information block, where the sub-carrier interval of the sub-carrier spacing common information field corresponding to PDCCH has a fixed value.

In some embodiments, the subclrierspacengCommon information field indicating the information bearing MIB redefines the subclrierspacengCommon information field in the MIB such that the subclrierspacengCommon information field is used to indicate available resources of the control resource set.

In addition, since the original sub-carrier spacing common information field in the main information block is used to indicate the subcarrier spacing of the PDCCH, the sub-carrier spacing common information field in the embodiment of the disclosure is redefined, and the sub-carrier spacing common information field cannot be used to indicate the subcarrier spacing of the PDCCH, so that it is required to specify that the subcarrier spacing of the PDCCH has a fixed value in advance.

In some embodiments, the subcarrier spacing of the sub-carrier corresponding PDCCH of the sub-carrier spacing command information field is fixed to 15kHz.

In some embodiments, the subclrierspacengcommon information field corresponds to 1 bit, and the indication information indicates available resources of the control resource set based on 1 bit.

For example, when the value of the subclrierspacengcommon information field is a first value, the indication information is used for indicating that the available resource of the control resource set is a first available resource; when the value of the subclrierspacengcommon information field is a second value, the indication information is used for indicating that the available resource of the control resource set is a second available resource. As shown in table 4 below.

TABLE 4 Table 4

In the embodiment of the disclosure, redefining the sub-carrier spacing command information field in the MIB enables the sub-carrier spacing command information field to be used for indicating available resources of the control resource set, so that the terminal can determine the available resources of the control resource set based on the sub-carrier spacing command information field of the MIB, and further the terminal can receive the PDCCH based on the available resources of the control resource set, thereby improving transmission reliability of the PDCCH.

In one method for determining resources provided in the embodiments of the present disclosure, indication information is carried in a partial bit information field of a PDCCH used for configuring a scheduling SIB in a primary information block.

Wherein the bit information field of the PDCCH for scheduling the SIB indicates a PDCCH-configSIB information field.

In the method for determining resources provided in the embodiments of the present disclosure, a part of the bit information field is a remaining bit information field of the PDCCH-configSIB information field that is not used for indicating resource information.

Wherein the resource information indicates the number of resources the network device is configured to control the set of resources, such as the number of resources shown in table 2. In the embodiment of the present disclosure, since the number of resources that can be carried by the frequency band with a smaller system bandwidth is limited, the embodiment of the present disclosure considers that the number of resources that the network device configures to the control resource set is set to a fixed value, such as 24. Then, referring to table 2 above, there are 6 cases where the number of resources corresponds to 24, that is, the bit information field indicating the resource information includes 6 cases, and there are 16 cases where the network device configures the resource information of the control resource set in table 2 above, that is, there remain 10 bit information fields not used for indicating the resource information. Accordingly, embodiments of the present disclosure contemplate indicating available resources of a control resource set with a remaining bit information field that does not indicate resource information.

In the embodiment of the disclosure, the PDCCH-configSIB information field is redefined, so that the PDCCH-configSIB information field can be used for indicating the number of resources of the control resource set and the available resources of the control resource set, the terminal can determine the available resources of the control resource set based on the PDCCH-configSIB information field of the MIB, and the terminal can receive the PDCCH based on the available resources of the control resource set, thereby improving the transmission reliability of the PDCCH.

In one method for determining resources provided in an embodiment of the present disclosure, a partial bit information field includes a first bit information field and a second bit information field, and the first bit information field and the second bit information field are different.

The first bit information field is used for indicating the number of resources configured to the control resource set by the network equipment. The second bit information field is used to indicate the available resources of the control resource set.

In some embodiments, the bits of the partial bit information field are fixed bits. The bit value of the second bit information field is determined based on the bit value of the first bit information field.

For example, the bits of the partial bit information field are 4 bits, and if the first bit information field indicates the number of resources allocated to the control resource set by the network device based on 1 bit, the second bit information field may indicate the available resources of the control resource set based on 2 bits or 3 bits. As yet another example, if the first bit information field indicates the number of resources allocated to the control resource set by the network device based on 2 bits, the second bit information field may indicate the available resources of the control resource set 0 based on 1 bit or 2 bits.

In some embodiments, the first bit information field indicates the number of resources the network device configures to the control resource set based on 1 bit, as shown in table 5. As shown in table 6, the second bit information field indicates available resources of the control resource set based on 2 bits.

In the embodiment of the disclosure, by redefining the PDCCH-configSIB information field in the MIB, the partial bit information field in the PDCCH-configSIB information field indicates the number of resources of the control resource set and the available resources of the control resource set independently, so that the terminal can determine the available resources of the control resource set based on the PDCCH-configSIB information field of the MIB, and the terminal can receive the PDCCH based on the available resources of the control resource set, thereby improving the transmission reliability of the PDCCH.

In the method for determining resources provided in the embodiments of the present disclosure, the partial bit information field includes a third bit information field, where the third bit information field is used to indicate available resources of the control resource set and the number of resources of the network device configured control resource set.

In some embodiments, the third bit information field of the partial bit information fields can jointly indicate the available resources of the control resource set and the number of resources of the network device configuration control resource set, as shown in table 7 below.

TABLE 7

Exemplary, bits of the third bit information fieldWhen the value is 6, the available resources of the control resource set are 14, and the number of the resources of the network equipment configuration control resource set is 24.

In the embodiment of the disclosure, by redefining the PDCCH-configSIB information field in the MIB, part of bit information fields in the PDCCH-configSIB information field are used for carrying out joint indication on the number of resources of the control resource set and the available resources of the control resource set, so that the terminal can determine the available resources of the control resource set based on the PDCCH-configSIB information field of the MIB, and further the terminal can receive the PDCCH based on the available resources of the control resource set, thereby improving the transmission reliability of the PDCCH.

In the method for determining resources provided in the embodiments of the present disclosure, the indication information is carried in a fourth bit information field of the main information block, where the fourth bit information field is used to indicate available resources of the control resource set.

Wherein the fourth bit information field is composed of a spare information field, a sub-carrier spacing command information field, and a different information field in a partial bit information field of the PDCCH-configSIB information field in the main information block.

Illustratively, the available resources of the control resource set are indicated with 1 bit in the spark information field and 1 bit in the subclrierspacengcommon information field, and the number of resources of the control resource set are configured by the network device with the PDCCH-configSIB information field. As shown in table 8, an indication map of the available resources of resource set 0 is shown for a combined indication of the spark information field and the subclrierspacengcommon information field.

TABLE 8

In the embodiment of the disclosure, different bit information fields in the MIB are utilized, so that the different bit information fields in the MIB can jointly indicate the number of resources of the control resource set and the available resources of the control resource set, so that the terminal can determine the available resources of the control resource set based on the different bit information fields of the MIB, and further the terminal can receive the PDCCH based on the available resources of the control resource set, and the transmission reliability of the PDCCH is improved.

In the method for determining resources provided by the embodiment of the present disclosure, a terminal needs to determine a starting position of an available resource of a control resource set in the control resource set, and further receives the available resource of the control resource set based on the starting position. As shown in fig. 4, the method comprises the following steps:

in step S31, a starting position of the available resources of the control resource set in the control resource set 0 is determined based on the instruction information.

In step S32, available resources of a control resource set are received based on the starting position.

Illustratively, if the available resources of the control resource set are 18, the reception is started at the start position, and the reception is stopped after the 18 resources are received.

In the embodiment of the disclosure, the starting position of the available resources of the control resource set in the control resource set is determined through the indication information, the available resources of the control resource set are received based on the starting position, the terminal is ensured to accurately receive the available resources and the PDCCH transmitted based on the available resources of the control resource set, and the transmission reliability of the PDCCH is improved.

In the resource determining method provided by the embodiment of the disclosure, a terminal determines a position and a resource offset value of a reference resource controlling a resource set based on indication information, and determines a starting position based on the position and the resource offset value of the reference resource.

In a method for determining resources provided by an embodiment of the present disclosure, the embodiment of the present disclosure further provides a method for determining a system bandwidth, as shown in fig. 5, including the following steps:

in step S41, the system bandwidth is determined based on the indication information and the subcarrier offset information.

In some embodiments, the relative location information of the available resources of the control resource set and the available resources of the control resource set is determined based on the indication information, and the system bandwidth is determined based on the relative location information of the available resources and the subcarrier offset information.

The relative position information of the available resources is directly indicated by the indication information, and represents the position deviation of the available resources and the PRB position of the reference resources, wherein one PRB consists of 12 subcarriers, and each subcarrier corresponds to 15KHz. The subcarrier offset information is indicated by the MIB, available resources are determined based on the subcarrier offset information, a bandwidth difference between a bandwidth of the control resource set and a system bandwidth is determined based on the relative position information of the available resources and the subcarrier offset information, and a bandwidth terminal of the control resource set can be configured to the resource determination of the control resource set based on the network device, so that the terminal determines the system bandwidth based on the bandwidth difference and the bandwidth of the control resource set.

Wherein the reference resource is configured for the network device, and the terminal can determine the location of the reference resource.

In some embodiments, the indication information and the subcarrier offset information are carried in a MIB.

In some embodiments, the terminal is able to determine the system bandwidth based on the MIB sent by the network device.

In the embodiment of the disclosure, the terminal can determine the system bandwidth based on the indication information and the subcarrier offset information, so that the terminal can acquire the system bandwidth before receiving the PDCCH without demodulating the PDCCH, and further, the terminal can process the PDCCH more accurately based on the system bandwidth.

Based on the same conception, the present disclosure also provides a resource determination method applied to a network device.

Fig. 6 is a flowchart illustrating a resource determination method, as shown in fig. 6, performed by a network device, according to an exemplary embodiment, including the following steps.

In step S51, indication information for indicating available resources of the control resource set is transmitted to the terminal.

In one embodiment, the control resource set is control resource set 0.

For example, the number of resources capable of being transmitted in the system bandwidth is 15, the number of resources configured by the network device for the control resource set is 24, the number of resources of the control resource set is greater than the number of resources capable of being transmitted in the system bandwidth, and it is required to determine which part of the 24 resources corresponding to the control resource set 0 is located in the system bandwidth.

In the embodiment of the disclosure, the network device sends the MIB to the terminal, so that the terminal determines available resources of the control resource set based on the MIB, and therefore the terminal receives the PDCCH based on the available resources of the control resource set, and the transmission reliability of the PDCCH is improved.

In one method for determining resources provided in the embodiments of the present disclosure, indication information is carried in a spark information field of MIB.

For example, when the value of the spark information field is the first value, the indication information is used for indicating that the available resource of the control resource set is the first available resource; when the value of the spark information field is the second value, the indication information is used for indicating that the available resource of the control resource set is the second available resource. As shown in table 9 below.
