Description

Technical Field

[0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a resource allocation method and apparatus, user equipment, a base station, and a readable storage medium. Background Art

[0002] In a 5G system, a base station sends a synchronization signal block on an initial access subband in a large bandwidth. For example, a synchronization signal block is sent on a 5 MHz subband in the middle of a 100 MHz system bandwidth. A first control resource set (CORESET) is sent on a first subband in a large bandwidth, and a second CORESET is sent on a second subband in a large bandwidth. Through the Physical Downlink Control Channel (PDCCH) in the first or second CORESET, the user equipment (UE) is scheduled to receive a public control message on the indicated Physical Downlink Shared Channel (PDSCH) to obtain remaining minimum system information (RMSI) or paging messages, etc.

[0003] The scheduling information in the PDCCH includes resource allocation information to tell the UE on which resource blocks (RBs) to receive the PDSCH.

[0004] However, the base station may not need to indicate the system bandwidth to the UE, so the UE cannot know the base station's system bandwidth. Because different UEs have different bandwidth capabilities, the base station cannot know the UE's bandwidth capabilities. With the significant increase in the system bandwidth of a single carrier in the 5G system, the existing resource allocation method is no longer suitable for the 5G system, and resource allocation efficiency is low.

[0063] Compared with the prior art, the technical solution of the embodiment of the present invention has the following beneficial effects:

[0064] Obtain reference point offset indication information sent by a base station, where the reference point offset indication information represents a frequency domain offset N of the reference point indicated by the base station relative to a specified resource block. Calculate the frequency domain position of the reference point based on the obtained first-category resource block position information and the reference point offset indication information.

[0065] Furthermore, the frequency domain offset N is indicated by the corresponding index S, and the number of bits of the index S is not greater than the number of bits of the frequency domain offset N.

[0066] Furthermore, the first type of resource blocks are resource blocks in the control resource set. Since CORESET and PDSCH use the same subband for transmission, when determining the RB for receiving PDSCH, the offset of the RB for receiving PDSCH relative to the reference point is small, thereby saving signaling overhead.

[0071] As mentioned above, the base station may not need to indicate the system bandwidth to the UE, so the UE cannot obtain the base station's system bandwidth. Because different UEs have different bandwidth capabilities, the base station cannot also obtain the UE's bandwidth capabilities. With the significant increase in the system bandwidth of a single carrier in the 5G system, the existing resource allocation method is no longer suitable for the 5G system, and resource allocation efficiency is low.

[0072] In this embodiment of the present invention, reference point offset indication information transmitted by a base station is obtained. The reference point offset indication information represents a frequency domain offset N of the reference point indicated by the base station relative to a designated resource block. The frequency domain position of the reference point is calculated based on the obtained first-category resource block position information and the reference point offset indication information. By combining the reference point with resource allocation information received from the scheduling information transmitted by the base station, the user equipment can quickly determine the resource blocks for receiving the physical downlink shared channel, thereby improving the resource allocation efficiency of the system.

[0073] In order to make the above-mentioned objects, features and beneficial effects of the embodiments of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0074] Reference Figure 1 , a flow chart of a resource allocation method in an embodiment of the present invention is given, and the following is a detailed description with reference to specific steps.

[0075] Step 11: In an idle state, after completing initial cell selection or cell reselection, obtain location information of the first type of resource blocks.

[0076] In a specific implementation, the first type of resource block can be a resource block in a synchronization signal block or a resource block in a control resource set.

[0077] In a specific implementation, when the first type of resource block is a resource block in a synchronization signal block, after the UE completes the initial cell selection or cell reselection, the location information of all resource blocks in the synchronization signal block can be obtained.

[0078] In a specific implementation, when the first type of resource block is an RB in a CORESET, the location information of all RBs in the CORESET can be obtained from the RMSI sent by the base station, that is, the frequency domain resource information of the CORESET can be obtained from the RMSI. The location information of all RBs in the CORESET can also be obtained from the Master Information Block (MIB) in the Physical Broadcast Channel (PBCH), that is, the frequency domain resource information of the CORESET can be obtained from the MIB.

[0079] Step 12: Obtain reference point offset indication information sent by the base station.

[0080] In a specific implementation, the reference point offset indication information includes a frequency domain offset N of the reference point indicated by the base station relative to a designated resource block, the designated resource block is one of the designated first type resource blocks, and N is an integer.

[0081] In a specific implementation, when the number of RBs is large, to save signaling overhead, the base station can indicate the frequency offset N using a corresponding index S, where the number of bits of the index S is no greater than the number of bits of the frequency domain offset N. The base station can select the frequency domain offset N of one of the available reference points relative to the designated resource block according to a preset rule. In other words, the protocol can predefine a set of possible values ​​for N, and the base station can indicate the value of N to the user equipment by indicating the index of the selected N value in the set of possible values.

[0082] In one embodiment of the invention, the offset N is expressed in units of RBs. It can be expressed in units of one RB or a preset number of RBs, where the preset number can be 2, 4, 7, or other values ​​as needed. This will not be described in detail here. When the offset N is expressed in units of multiple RBs, the number of bits occupied by the index S can be further reduced, further saving signaling overhead.

[0083] For example, all RBs are offset by N RBs relative to a specified resource block. N can have a total of 100 values: 0, 1, 2, ..., 98, 99. The preset set of possible values ​​for N is {0, 10, 20, 30, ..., 80, 90}, with a total of 10 values. The corresponding index set for this set of possible values ​​is {0, 1, 2, 3, ..., 8, 9}. For example, when the frequency domain offset N is 3, the corresponding reference point is offset by 30 resource blocks relative to the specified resource block.

[0084] In the 5G system, synchronization signals and broadcast channels can be sent in the form of synchronization signal blocks. The primary synchronization signal (PSS), secondary synchronization signal (SSS) and PBSH are in the synchronization signal block (SS-Block). The 5G system introduces the beam scanning function. Each synchronization signal block can be regarded as a beam resource in the beam scanning process. Multiple synchronization signal blocks constitute a synchronization signal burst (SS-burst). A synchronization signal burst can be regarded as a relatively concentrated resource containing multiple beams. Multiple synchronization signal bursts constitute a synchronization signal burst set (SS-burst-set). The repeated transmission of synchronization signal blocks on different beams is a beam scanning process. Through beam scanning training, the UE can sense which beam has the strongest signal.

[0085] In a specific implementation, when the types of the first type of resource blocks are different, the designated resource blocks are also different.

[0086] In one embodiment of the present invention, when the first type of resource block is a synchronization signal block, the designated resource block may be a designated resource block in a synchronization signal or a designated resource block in a physical broadcast channel.

[0087] When the designated resource block is a designated resource block in a synchronization signal block, the designated resource block may be a resource block with the smallest index in the synchronization signal, or a resource block with the largest index in the synchronization signal, or a resource block with any index between the smallest index and the maximum index in the synchronization signal.

[0088] When the designated resource block is a designated resource block in a physical broadcast channel, the designated resource block can be a resource block with the minimum index of the physical broadcast channel, a resource block with the maximum index of the physical broadcast channel, or a resource block with any index between the minimum index and the maximum index in the physical broadcast channel.

[0089] In another embodiment of the present invention, when the first type of resource block is an RB in a CORESET, the designated resource block may be an RB with the smallest index in the CORESET, or an RB with the largest index in the CORESET, or an RB with any index between the smallest index and the maximum index in the CORESET.

[0090] In specific implementations, the base station can select which RB to use as the designated resource block based on the actual application scenario, the set resource block designation conditions, or the adopted protocol. All RBs in the synchronization signal block or RBs with any index in all RBs in the CORESET can be used as designated resource blocks, which provides high flexibility and can effectively improve resource allocation efficiency in large bandwidth situations in 5G systems.

[0091] In a specific implementation, when the first type of resource block is the RB in the synchronization signal block, the reference point offset indication information can be obtained from the RMSI sent by the received base station, or from the received MIB, or from the received downlink control information (Downlink Control Information, DCI).

[0092] In a specific implementation, when the first type of resource block is an RB in a CORESET, the reference point offset indication information can be obtained from the RMSI received from the base station, or from the MIB received from the base station.

[0093] Step 13: Calculate the frequency domain position of the reference point according to the acquired first-type resource block position information and the reference point offset indication information.

[0094] In a specific implementation, the UE may calculate the frequency domain position of the reference point according to the obtained position information of the first type of resource blocks and the obtained reference point offset indication information.

[0095] In a specific implementation, the designated resource block specifically refers to which resource block in the first type of resource blocks may be pre-configured by the UE, or may be sent to the UE by the base station through signaling.

[0096] For example, the UE may determine the position of the reference point according to the determined position of the designated resource block and the frequency domain offset N, and calculate the frequency domain position of the reference point.

[0097] Step 14: When the scheduling information sent by the base station is received, a resource block for receiving a physical downlink shared channel is determined according to the frequency domain position of the reference point and the resource allocation information included in the scheduling information.

[0098] In a specific implementation, when the UE receives the scheduling information sent by the base station, the UE can obtain the resource allocation information from the scheduling information. The UE can determine the resource block for receiving the Physical Downlink Shared Channel (PDSCH) based on the frequency domain position of the reference point and the resource allocation information.

[0099] In a specific implementation, the resource block corresponding to the reference point is the starting resource block. When determining the resource block for receiving the PDSCH, the resource block corresponding to the reference point is used as the counting reference point, and counting starts, and the resource block for receiving the PDSCH is determined based on the resource allocation information included in the scheduling information.

[0100] In a specific implementation, the resource block index corresponding to the reference point may be 0 or other values.

[0101] It can be seen from the above scheme that the reference point offset indication information sent by the base station is obtained, and the reference point offset indication information represents the frequency domain offset N of the reference point indicated by the base station relative to the specified resource block. Based on the obtained first-category resource block position information and the reference point offset indication information, the frequency domain position of the reference point is calculated. Since the system bandwidth of a single carrier in the 5G system will increase significantly, in the case of a large system bandwidth, the user equipment can quickly determine the resource block of the physical downlink shared channel by combining the reference point with the resource allocation information in the scheduling information received from the base station, thereby improving the resource allocation efficiency of the system in the idle state.

[0102] In a specific implementation, since the base station cannot obtain the bandwidth capability of the user equipment in the idle state, in one embodiment of the present invention, the maximum resource block index value is the maximum resource block index value under the minimum bandwidth.

[0103] In a specific implementation, the minimum bandwidth may be the minimum of the system bandwidth and the minimum user equipment bandwidth. For example, the RB index corresponding to the 5 MHz minimum user equipment bandwidth is 24.

[0104] In a specific implementation, the minimum bandwidth and the corresponding maximum resource block index are related to the frequency band corresponding to the cell, such as a frequency range or frequency band, and can be pre-defined by the adopted protocol.

[0105] Furthermore, the first resource block is a resource block in CORESET. Since CORESET and PDSCH use the same subband for transmission, when determining the RB for receiving PDSCH, the offset of the RB for receiving PDSCH relative to the reference point is small, thereby saving signaling overhead.

[0106] Reference Figure 2 , provides a flow chart of another resource allocation method according to an embodiment of the present invention. The resource allocation method is used by a base station to allocate resources to a UE, and may specifically include the following steps:

[0107] Step 21: In an idle state, after detecting that the user equipment completes initial cell selection or cell reselection, first-category resource block location information is sent to the user equipment.

[0108] In a specific implementation, the first type of resource block can be a resource block in a synchronization signal block or a resource block in a control resource set.

[0109] When the first type of resource block is a resource block in a synchronization signal block, when the UE performs initial cell selection or cell reselection, the location information of all resource blocks in the synchronization signal block is sent to the UE. After the UE completes the initial cell selection or cell reselection, the location information of all resource blocks in the synchronization signal block can be obtained.

[0110] When the first type of resource blocks are resource blocks in CORESET, the base station may send the location information of the first type of resource blocks to the UE through RMSI, or may send the location information of the first type of resource blocks to the UE through MIB in PBCH.

[0111] In practice, in idle mode, the UE monitors the PDCCH, blindly detects its common search space, and obtains DCI. It then receives public control information, such as RMSI and paging messages, from the indicated PDSCH. In idle mode, the PDCCH that the UE monitors is the common control channel, which can broadcast information using beam timing within a synchronization signal block or by scanning beams. The PDCCH resource is called a CORESET.

[0112] The MIB carried by the base station in the PBCH can indicate that the user equipment needs to monitor a CORESET in the idle state, so that the user equipment can blindly detect the PDCCH in the CORESET in the idle state to obtain RMSI, etc. This CORESET can be called the first CORESET.

[0113] The RMSI may indicate another CORESET that the user equipment needs to monitor in the idle state, so that the user equipment can blindly detect the PDCCH within the CORESET in the idle state to obtain paging messages, etc. This CORESET may be referred to as a second CORESET.

[0114] Step 22: Send reference point offset indication information to the user equipment.

[0115] In a specific implementation, the base station can send reference point offset indication information to the user equipment, and the reference point offset indication information includes the frequency domain offset N of the reference point indicated to the user equipment relative to the specified resource block, wherein the specified resource block is one of the first type of resource pools specified, and N is an integer.

[0116] In a specific implementation, when the designated resource block is a resource block in a synchronization signal block, the designated resource may be a resource block in a synchronization signal or a resource block in a physical broadcast channel.

[0117] When the designated resource block is a resource block in a synchronization signal, the base station may use the resource block with the smallest index in the synchronization signal as the designated resource block, or use the resource block with the largest index in the synchronization signal as the designated resource block, or use the resource block with any index between the smallest index and the maximum index in the synchronization signal as the designated resource block.

[0118] When the designated resource block is a resource block in a physical broadcast channel, the base station may use the resource block with the minimum index of the physical broadcast channel as the designated resource block, or use the resource block with the maximum index of the physical broadcast channel as the designated resource block, or use the resource block with any index between the minimum index and the maximum index in the physical broadcast channel as the designated resource block.

[0119] In a specific implementation, when the designated resource block is a resource block in a control resource set, the base station may use the resource block with the smallest index in the control resource set as the designated resource block, or may use the resource block with the largest index in the control resource set as the designated resource block, or may use the resource block with any index between the smallest index and the maximum index in the control resource set as the designated resource block.

[0120] In a specific implementation, the base station can select which RB to use as the designated resource block based on the actual application scenario, the set resource block designation conditions, or the adopted protocol. When selecting the designated resource block, all RBs in the synchronization signal block and RBs with any index in all RBs in the CORESET can be used as designated resource blocks, which is highly flexible and can effectively improve resource allocation efficiency in large bandwidth situations in 5G systems.

[0121] In a specific implementation, when the types of the first type of resource blocks are different, the manner in which the base station sends the reference point offset indication information to the user equipment is also different.

[0122] For example, when the first type of resource block is a resource block in a synchronization signal block, the base station can send reference point offset indication information to the user equipment through RMSI, or send reference point offset indication information to the user equipment through MIB in PBCH, or send reference point offset indication information to the user equipment through DCI.

[0123] For another example, when the first type of resource blocks are resource blocks in a control resource set, the base station may send reference point offset indication information to the user equipment through RMSI, or may send reference point offset indication information to the user equipment through MIB in PBCH.

[0124] In a specific implementation, the frequency domain offset N is suitable for being indicated by a corresponding index S, and the number of bits of the index S is not greater than the number of bits of the frequency domain offset N.

[0125] In a specific implementation, the frequency domain offset N of the reference point relative to the designated resource block indicated by the base station to the user equipment may be the frequency domain offset N of one reference point relative to the designated resource block selected by the base station from a set of available reference points according to a preset rule. That is, the base station may indicate the selected value of N to the user equipment based on a set of available values ​​for N predefined by the protocol by indicating its index within the set of available values, thereby reducing the number of bits occupied by the offset N and thereby reducing signaling overhead.

[0126] In a specific implementation, after receiving the reference point offset indication information, the UE may calculate the frequency domain position of the reference point according to the reference point offset indication information and the acquired position information of the first type of resource blocks.

[0127] Step 23: Send scheduling information to the user equipment.

[0128] In a specific implementation, the base station may send scheduling information to the UE, wherein the scheduling information includes resource allocation information. The user equipment may determine a resource block for receiving the physical downlink shared channel based on the frequency domain position of the reference point and the resource allocation information included in the scheduling information.

[0129] For example, the base station can schedule the user equipment to receive PDSCH through the PDCCH in the first CORESET or the second CORESET to obtain RMSI or paging message, etc. The scheduling information in the PDCCH includes resource allocation information, which can inform the user equipment on which resource blocks to receive PDSCH.

[0130] In a specific implementation, the resource block corresponding to the reference point is the starting resource block. When the user equipment determines the resource block for receiving the physical downlink shared channel, the resource block corresponding to the reference point is used as the starting resource block, and the resource block corresponding to the reference point is used as the counting reference point. According to the resource allocation information included in the scheduling information, the resource block for receiving the physical downlink shared channel is determined.

[0131] In a specific implementation, the resource block index corresponding to the reference point may be 0 or other values.

[0132] Using the above solution, the base station sends the first type of resource block position information and reference point offset indication information to the user equipment. The reference point offset indication information represents the frequency domain offset N of the reference point indicated by the base station relative to the specified resource block. The user equipment can calculate the frequency domain position of the reference point based on the obtained first type of resource block position information and the reference point offset indication information. Since the system bandwidth of a single carrier in the 5G system will increase significantly, when the system bandwidth is large, the use of the reference point combined with the resource allocation information in the scheduling information can enable the user equipment to quickly determine the resource block for receiving the physical downlink shared channel, thereby improving the resource allocation efficiency of the system in the idle state.

[0133] In a specific implementation, since the base station cannot obtain the bandwidth capability of the user equipment in the idle state, in one embodiment of the present invention, the maximum resource block index value is the maximum resource block index value under the minimum bandwidth.

[0134] In a specific implementation, the minimum bandwidth is the minimum of the system bandwidth and the minimum user equipment bandwidth. For example, the RB index corresponding to the 5 MHz minimum user equipment bandwidth is 24.

[0135] In a specific implementation, the minimum bandwidth and the corresponding maximum resource block index are related to the frequency band corresponding to the cell, such as a frequency range or frequency band, and can be pre-defined by the adopted protocol.

[0136] In a specific implementation, the resource allocation method used by the base station to allocate resources to the user equipment can refer to the description of the resource allocation method provided in the above embodiment, and will not be repeated here.
