Referring to
It should be noted that the technical solution of embodiments of the disclosure may be applied to various communication systems, such as, a long term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or another future new mobile communication system.
The network device 101 in embodiments of the disclosure is an entity for sending or receiving a signal in a network side. For example, the network device 101 may be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. Detailed technologies and detailed device forms employed by the network device are not limited in embodiments of the disclosure. The network device provided in embodiments of the disclosure may be combined by a central unit (CU) and a distributed unit (DU). The CU may also be referred to as a control unit. A protocol layer of the network device, such as the base station, may be separated by employing a CU-DU structure, in which, part of functions of the protocol layer are centrally controlled by the CU, while part or all of remaining functions of the protocol layer are distributed in the DU. The DU is controlled by the CU.
The terminal 102 in embodiments of the disclosure is an entity for receiving or sending a signal in a user side, such as, a mobile phone. The terminal may also be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), or the like, or may be a reduced capability UE (RedCap UE), an evolved reduced capability UE (eRedCap UE), or the like. The terminal may be an automobile with a communication function, a smart automobile, a mobile phone, a wearable device, a pad, a computer with a wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in a remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in a transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like. Detailed technologies and detailed device forms employed by the terminal are not limited in embodiments of the disclosure.
In the related art, a control resource set (CORESET) for the terminal occupies 1 to 3 continuous symbols in a time domain, and frequency domain resources are configured in a frequency domain in a way similar to a PDSCH resource allocation type 0. A basic granularity for allocating the frequency domain resources is 6 resource blocks (RBs).
In Release 18, it is proposed that a bandwidth is further reduced for a RedCap terminal, to support a service type which is not high in data rate and is sensitive to manufacturing cost, such as a factory sensor, and at the same time, still possibly to support a configuration of a sub-carrier spacing such as 15 KHz or 30 KHz, causing a reduction in available frequency domain resources in a bandwidth range.
When the sub-carrier spacing (SCS) is 30 KHz, 11 available RBs merely exist at a bandwidth with 5 MHz. In case that a configuration way on frequency domain resources of the CORESET in the related art is still employed, and that configuration is performed on the frequency domain resources of the CORESET with 6 RBs as the basic granularity, for a physical downlink control channel (PDCCH), some frequency domain resources in the bandwidth range may not be utilized all the time.

At block 201, indication information sent by a network device is received.
In embodiments of the disclosure, the terminal receives the indication information sent by the network device. The indication information indicates the terminal to determine frequency domain resources occupied by a control resource set (CORESET).
In some implementations, the indication information is configured to indicate that the frequency domain resources occupied by the CORESET are continuous frequency domain resource units.
In some implementations, the indication information includes at least one bit, and each bit of the indication information may indicate whether a group of frequency domain resource units corresponding to the bit is the frequency domain resources occupied by the CORESET.
The frequency domain resource unit may be an RB, a physical resource block (PRB), a virtual resource block (VRB), a common resource block (CRB), or the like.
At block 202, the frequency domain resources occupied by the CORESET are determined based on the indication information, in which, the frequency domain resources occupied by the CORESET are continuous frequency domain resource units; or, the frequency domain resources occupied by the CORESET are at least two discontinuous groups of frequency domain resource units. The group of frequency domain resource units is obtained by dividing a plurality of frequency domain resource units based on one of at least two granularities.
In embodiments of the disclosure, the terminal may determine the frequency domain resources occupied by the CORESET based on the indication information.
In an implementation of embodiments of the disclosure, the frequency domain resources occupied by the CORESET are the continuous frequency domain resource units.
In some implementations, the terminal may determine a start position of the frequency domain resources occupied by the CORESET and a size of the frequency domain resources occupied by the CORESET based on the indication information, thus determining the frequency domain resources occupied by the CORESET.
In some implementations, the terminal may obtain the start position of the frequency domain resources occupied by the CORESET specified in a protocol, and determine the size of the frequency domain resources occupied by the CORESET based on the indication information, thus determining the frequency domain resources occupied by the CORESET.
In some implementations, the terminal may obtain the start position of the frequency domain resources occupied by the CORESET specified in the protocol, and determine a maximum aggregation level of the terminal and the number of time domain symbols based on the indication information, and further determine the size of the frequency domain resources occupied by the CORESET based on the maximum aggregation level of the terminal and the number of time domain symbols, thus determining the frequency domain resources occupied by the CORESET.
In some implementations, the size of the frequency domain resources occupied by the CORESET may also be determined based on the maximum aggregation level of the terminal, the number of PDCCH candidate channels supported by the maximum aggregation level, and the number of the time domain symbols.
Alternatively, the size of the frequency domain resources may match a bandwidth supported by the terminal, to avoid resource waste. In embodiments of the disclosure, the matching refers to that the size of the frequency domain resources is as close as possible to a length of the bandwidth supported by the terminal.
It may be understood that, in embodiments of the disclosure, the bandwidth supported by the terminal may be a bandwidth, or a bandwidth part (BWP).
In embodiments of the disclosure, the size of the frequency domain resources may also be referred to as a length of the frequency domain resources, that is, the number of frequency domain resource units included in the frequency domain resources.
In another implementation of embodiments of the disclosure, the frequency domain resources occupied by the CORESET are the at least two discontinuous groups of frequency domain resource units. The group of frequency domain resource units is obtained by dividing the plurality of frequency domain resource units based on one of at least two granularities.
In some implementations, the indication information includes at least one bit. The indication information may indicate a position of the at least one group of frequency domain resource units in the plurality of frequency domain resource units configured by the network device. Each bit of the indication information may indicate whether the group of frequency domain resource units corresponding to the bit is the frequency domain resources occupied by the CORESET.
In some implementations, the granularity is determined based on at least one of: granularity indication information; a bandwidth supported by the terminal; the number of bits of the indication information; the number of resource element groups (REGs) occupied by a control channel element (CCE); or the number of time domain symbols configured by the network device. An allocated granularity may be configured flexibly based on an actual condition, thus further improving a resource utilization rate, and avoiding the resource waste.
In some embodiments, in response to there being a remaining REG that is not mapped to a CCE, the remaining REG is released, which may further improve the resource utilization rate, and avoid the resource waste.
As described above, in the related art, the indication information indicates that the frequency domain resources occupied by the CORESET are the at least two discontinuous groups of frequency domain resource units. The group of frequency domain resource unit includes 6 frequency domain resource units, and the allocated granularity of the frequency domain resources of the CORESET is 6.
In some implementations of embodiments of the disclosure, the at least two discontinuous groups of frequency domain resource units occupied by the CORESET are obtained by dividing the plurality of frequency domain resource units based on one of at least two granularities, that is, the granularity allocated to the frequency domain resources is changed.
In some implementations of embodiments of the disclosure, the frequency domain resources occupied by the CORESET are the continuous frequency domain resource units, that is, an allocation way on the frequency domain resources is changed.
In conclusion, the indication information sent by the network device is received, and the frequency domain resources occupied by the CORESET are determined based on the indication information. The frequency domain resources occupied by the CORESET are the continuous frequency domain resource units; or, the frequency domain resources occupied by the CORESET are the at least two discontinuous groups of frequency domain resource units. The group of frequency domain resource units is obtained by dividing the plurality of frequency domain resource units based on one of at least two granularities. By changing the allocation way on the frequency domain resources for the terminal or flexibly configuring the allocated granularity of the frequency domain resources, the terminal may support a larger aggregation level as much as possible, thus effectively improving a transmission performance of a downlink channel, enhancing a coverage of the downlink channel, improving a system communication efficiency, effectively reducing the resource waste, and improving the resource utilization rate.

At block 301, indication information sent by a network device is received.
In embodiments of the disclosure, the terminal receives the indication information sent by the network device. The indication information is configured to indicate the terminal to determine frequency domain resources occupied by a CORESET.
In embodiments of the disclosure, the indication information may be a resource indication value (RIV) joint code, and the terminal may determine a start position and a length of frequency domain resources allocated to the CORESET based on the RIV code.
The RIV code is determined by the network device based on the start position and the length of the frequency domain resources allocated to the CORESET. The terminal may decode the RIV code after receiving the RIV code, and determine the start position and the length of the frequency domain resources allocated to the CORESET.
As an example, the RIV code may be determined in the following way.
If (L−1)≤|N/2|, RIV=N (L−1)+RBSTART; otherwise, RIV=N (N−L+1)+ (N−1−RBSTART), where N represents the number of frequency domain resource units included in a bandwidth supported by the terminal, L represents the size of the frequency domain resources, RBSTART represents the start position of the frequency domain resources, and RIV represents the RIV code and is a value represented by at least 1 bit.
At block 302, a start position of the frequency domain resources occupied by the CORESET and a size of the frequency domain resources occupied by the CORESET are determined based on the indication information.
In embodiments of the disclosure, the terminal may receive the RIV code sent by the network device, and may determine the start position of the frequency domain resources occupied by the CORESET and the size of the frequency domain resources occupied by the CORESET based on the RIV code.
In some implementations, the terminal may determine the start position and the length of the frequency domain resources corresponding to an RIV value of the RIV code by looking up a table based on the RIV value.
In some implementations, the terminal may also decode the RIV code in a calculation way, to determine the start position and the length of the frequency domain resources corresponding to the RIV value.
As an example, the RIV code may be decoded in the following way.
It is assumed that P represents the size of the frequency domain resources, O represents the start position of the frequency domain resources, N represents the number of frequency domain resource units included in the bandwidth supported by the terminal, and x represents the RIV value, and it is defined:
a=floor (x/N)+1, b=x mod N, where floor (•) represents rounding down, and mod represents a modulus operation.
Then:
if a+b>N, P=N+2−a, O=N−1−b; otherwise, P=a, O=b.
In embodiments of the disclosure, the terminal determines the frequency domain resources occupied by the CORESET after determining the start position and the length of the frequency domain resources occupied by the CORESET.
It may be understood that, in embodiments of the disclosure, the frequency domain resources occupied by the CORESET are continuous frequency domain resource units.
Further, in some embodiments, in response to there being a remaining REG that is not mapped to a CCE, the remaining REG is released. The REG that may not be mapped to the CCE is released to other terminals or channels for use, to further improve the resource utilization rate and reduce the resource waste.
In some implementations, in order to further save resources and reduce waste of the frequency domain resources, when the size of the frequency domain resources is configured, the network device determines a product of the size of the frequency domain resources and the number of symbols occupied by the CORESET in a time domain configured by the network device, and the product may be exactly divided by 6, that is, the number of REGs included in the CORESET is an integer multiple of 6.
It should be noted that, since a transmission of the PDCCH is performed on at least one CCE, one CCE includes 6 REGs. In case that the product of the size of the frequency domain resources and the number of symbols occupied by the CORESET in the time domain configured by the network device is not an integer multiple of 6, there may be one or more remaining REGs that may not be mapped to the CCE. The one or more remaining REGs may not be configured to the transmission of the PDCCH all the time, causing waste of the frequency domain resources. In case that the product of the size of the frequency domain resources and the number of symbols occupied by the CORESET in the time domain configured by the network device may be exactly divided by 6, all the REGs included in the CORESET may be mapped to the CCE.
In some embodiments, an aggregation level may also be considered in a procedure of determining of the size of the frequency domain resources. When there is a relatively large aggregation level, the size of the frequency domain resources matches the bandwidth supported by the terminal, and the size of the frequency domain resources is as close as possible to a length of the bandwidth supported by the terminal.
In conclusion, the indication information sent by the network device is received, the start position of the frequency domain resources occupied by the CORESET and the size of the frequency domain resources occupied by the CORESET are determined based on the indication information. By changing the allocation way of the frequency domain resources for the terminal, the terminal may support a larger aggregation level as much as possible, thus effectively improving a transmission performance of a downlink channel, enhancing a coverage of the downlink channel, improving a system communication efficiency, effectively reducing the resource waste, and improving a resource utilization rate.

In an example, alternatively, the granularity may be 2, 3, or 6. In other words, one group of frequency domain resources of the CORESET may include 2 frequency domain resource units, 3 frequency domain resource units, or 6 frequency domain resource units. That is, 1 bit in the indication information may indicate 2 corresponding frequency domain resource units, 3 corresponding frequency domain resource units, or 6 corresponding frequency domain resource units.
It should be noted that, in embodiments of the disclosure, each group of frequency domain resources in the at least one group of frequency domain resources of one CORESET includes the same number of frequency domain resource units.
In embodiments of the disclosure, an allocated granularity of the frequency domain resources is changed, thus flexibly configuring the allocated granularity of the frequency domain resources, such that the terminal may support a larger aggregation level as much as possible.
In some embodiments, the granularity may be determined based on at least one of:
Alternatively, the allocated granularity of the frequency domain resources of the CORESET may be determined from a granularity set including at least two granularities based on the granularity indication information. For example, the granularity set is {2, 3, 6}, and the terminal may determine the allocated granularity of the frequency domain resources of the CORESET from the granularity set {2, 3, 6} based on the granularity indication information.
Alternatively, the allocated granularity of the frequency domain resources of the CORESET may be determined based on the bandwidth supported by the terminal and the number of bits of the indication information. The number of frequency domain resource units indicated by each bit of the indication information may be determined based on the bandwidth supported by the terminal and the number of bits of the indication information, and then the allocated granularity of the frequency domain resources of the CORESET is also determined.
It may be understood that, in embodiments of the disclosure, the bandwidth supported by the terminal may be a bandwidth, or may be a BWP.
Alternatively, the allocated granularity of the frequency domain resources of the CORESET may be determined based on the number of REGs occupied by the CCE and the number of time domain symbols configured by the network device.
Alternatively, the allocated granularity of the frequency domain resource of the CORESET may be determined based on the number of time domain symbols configured by the network device. In an example, for example, in case that the number of time domain symbols configured by the network device is 2 or 4, it is determined that the allocated granularity of the frequency domain resources of the CORESET is 3; and incase that the number of time domain symbols configured by the network device is 3, it is determined that the allocated granularity of the frequency domain resources of the CORESET is 2.
In some implementations, there is at least one combination of the number of time domain symbols and a granularity, and the number of time domain symbols and a granularity corresponding to an index may be indicated by the index.
Further, in some embodiments, in response to there being a remaining REG that is not mapped to a CCE, the remaining REG is released. The REG that may not be mapped to the CCE may be released to other terminals or channels for use, to further improve the resource utilization rate and reduce the resource waste.
In some embodiments, when there is a relatively large aggregation level, the frequency domain resources of the CORESET matches the bandwidth supported by the terminal, and the size of the frequency domain resources is as close as possible to the bandwidth supported by the terminal.
In conclusion, the indication information sent by the network device is received, the frequency domain resources occupied by the CORESET are determined based on the indication information. The frequency domain resources occupied by the CORESET are at least two discontinuous groups of frequency domain resource units, and the group of frequency domain resource units is obtained by dividing THE plurality of frequency domain resource units based on one of at least two granularities. By flexibly configuring the allocated granularity of the frequency domain resources, the terminal may support a larger aggregation level as much as possible, thus effectively improving a transmission performance of a downlink channel, enhancing a coverage of the downlink channel, improving a system communication efficiency, effectively reducing the resource waste, and improving the resource utilization rate.
It should be noted that a resource configuration way on CORESET #0 is different from that on other CORESETs. Therefore, in embodiments of the disclosure, in case that the CORESET is the CORESET #0, the indication information is remaining minimum system information (RMSI), and the RMSI is configured to determine a length of the frequency domain resources for the CORESET #0 and a corresponding number of symbols for the CORESET #0 from at least one combination of the length of the frequency domain resources and the corresponding number of symbols agreed by a protocol.
In an example, when an SCS is 30 kHz, the at least one combination of the length of the frequency domain resources and the corresponding number of symbols agreed by the protocol may be illustrated in a following table.
In order to improve the resource utilization rate, to reduce unnecessary resource waste, and to improve transmission efficiency and quality, when the combination of the length of the frequency domain resources for the CORESET #0 and the corresponding number of symbols for the CORESET #0 is designed, there needs to be met as much as possible that the length of the frequency domain resources does not exceed the bandwidth supported by the terminal, and the number of REGs (that is, a product of the number of RBs and the number of symbols) included in the combination of the length of the frequency domain resources and the corresponding number of symbols is an integer multiple of 6 as much as possible.
It may be understood that the table is merely an example, for example, some possible combinations of the length of the frequency domain resources for the CORESET #0 and the corresponding number of symbols for the CORESET #0, or more combinations may be designed to meet and adapt to more scenes and bandwidth requirements. The table is merely an example but does not limit embodiments of the disclosure.

In some embodiments, in response to there being a remaining REG that is not mapped to a CCE, the remaining REG is released, such that the resource utilization rate may be further improved, and the resource waste is avoided.
In embodiments of the disclosure, in case that the CORESET is CORESET #0, the indication information is RMSI, and the RMSI is configured to determine a length of the frequency domain resources for the CORESET #0 and the corresponding number of symbols for the CORESET #0 from at least one combination of the length of the frequency domain resources and the corresponding number of symbols agreed by the protocol.
