Technical Field

Background

In a network communication system, information may be transmitted between different network devices over an operating bandwidth. If the working bandwidth is the downlink bandwidth, the method can be used for the network equipment to send wireless signals to the terminal equipment; if the working bandwidth is the uplink bandwidth, the working bandwidth can be used for the terminal equipment to send the wireless signal to the network equipment.

However, in the full duplex scenario of the sub-bands, the uplink sub-band and the downlink sub-band occur simultaneously in the working bandwidth, the existing frequency domain resource allocation mode is continuously mapped from low to high, and the allocation period is long, so that the wireless signal may be mapped to the unavailable sub-band, and thus the reliability of the resource allocation is poor.

The technical scheme shown in the application is described in detail by specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and for the same or similar content, the description will not be repeated in different embodiments.

Fig. 2 is a flow chart of a resource allocation method according to an embodiment of the present application. Referring to fig. 2, the method may include:

s201, the network equipment acquires configuration information of the wireless signals.

The network device may obtain configuration information of the wireless signal over the 5G network, which may be used to indicate a location of the at least one physical resource block (physical resource block, PRB). PRB refers to resources of 12 consecutive carriers in the frequency domain. The location of the PRBs may be represented by an identification.

Next, PRBs will be described with reference to fig. 3.

Fig. 3 is a schematic diagram of a physical resource block according to an embodiment of the present application. Referring to fig. 3, an operating bandwidth may be divided into a plurality of PRBs according to frequencies. One PRB is composed of 12 subcarriers in the frequency domain, and the bandwidth is 180kHz.

The configuration information may be represented in the following 2 ways:

mode 1: the configuration information may be represented by a bitmap.

A plurality of bits may be included in the bitmap, each bit being used to indicate an identity of a corresponding PRB.

Next, a bit map will be described with reference to fig. 4.

Fig. 4 is a schematic diagram of a bit map according to an embodiment of the present application. Referring to fig. 4, the number of PRBs corresponding to the bitmap may be 13, and each PRB may have a corresponding identifier, which is 0, 1, 2, … …, and 12 respectively. Wherein consecutive 2 PRBs may be grouped into a group of PRBs. For example, PRB-0 and PRB-1 may constitute group 1 PRB, PRB-2 and PRB-3 may constitute group 2 PRB, … …, PRB-11 and PRB-11 may constitute group 6 PRB, with PRB-12 being group 7 PRB.

As in fig. 4, the bit map may be "1011000", where each bit is used to indicate a set of PRBs. For example, bit 1 in the bitmap is 1, which may be used to indicate the set of PRBs that are PRB-0 and PRB-1, indicating that PRB-0 and PRB-1 are to be used; bit 2 in the bit map is 0, which indicates that the set of PRBs, PRB-2 and PRB-3, indicates that PRB-2 and PRB-3 are not occupied. The first bit in the bitmap is the highest bit, and the corresponding lowest position in the frequency domain can be mapped sequentially.

Mode 2: the configuration information may be represented by virtual resource blocks (virtual resource block, VRBs).

The configuration information may include an identifier of at least one VRB, where the identifier of the VRB is used to determine an identifier of a corresponding PRB.

The manner in which VRBs are mapped to PRBs may include: centralized and distributed. Next, a mapping relationship between VRBs and PRBs will be described with reference to fig. 5A to 5B.

Fig. 5A is a schematic diagram of a centralized mapping provided in an embodiment of the present application. Referring to fig. 5A, the apparatus includes a plurality of VRBs and a plurality of PRBs, where each VRB and PRB have a corresponding identifier. For example, if there are 13 VRBs, the corresponding identifiers may be 0, 1, 2, … …, 12, respectively; if there are 13 PRBs, the corresponding identifiers may be 0, 1, 2, … …, 12, respectively. In the centralized mapping mode, VRBs and PRBs are in one-to-one correspondence, i.e. one VRB may determine one corresponding PRB. As in fig. 5A, if VRB-3, VRB-4, and VRB-5 are 3 consecutive VRBs, 3 consecutive PRBs corresponding to the VRBs can be determined, and PRB-3, PRB-4, and PRB-5 are respectively determined.

Fig. 5B is a schematic diagram of a distributed mapping according to an embodiment of the present application. Referring to fig. 5B, the apparatus includes a plurality of VRBs and a plurality of PRBs, where each VRB and PRB have a corresponding identifier. For example, if there are 13 VRBs, the corresponding identifiers may be 0, 1, 2, … …, 12, respectively; if there are 13 PRBs, the corresponding identifiers may be 0, 1, 2, … …, 12, respectively.

In a distributed mapping manner, VRBs and PRBs are not in one-to-one correspondence, and consecutive VRBs may be mapped to discontinuous PRBs. As shown in FIG. 5B, VRB-3, VRB-4, VRB-5 are consecutive VRBs. Wherein, VRB-3 can be used to determine PRB-2, VRB-4 can be used to determine PRB-6, VRB-5 can be used to determine PRB-10, PRB-2, PRB-6, PRB-10 are discontinuous PRBs.

S202, the network equipment sends configuration information to the terminal equipment.

The network device may send configuration information to the terminal device over the 5G network. For example, the configuration information of the wireless signals may include VRB-3, VRB-4, VRB-5, where VRB-3 may be used to determine PRB-2, VRB-4 may be used to determine PRB-6, and VRB-5 may be used to determine PRB-10.

S203, the terminal equipment determines the frequency domain resource to be used by the wireless signal according to the configuration information.

For example, if the configuration information includes VRB-3, VRB-4, VRB-5, and VRB-3 may be used to determine PRB-2, VRB-4 may be used to determine PRB-6, VRB-5 may be used to determine PRB-10, then the terminal device may determine that the frequency domain resources to be used by the wireless signal are PRB-2, PRB-6, and PRB-10.

The resource allocation method may include a resource allocation method for a physical uplink and downlink shared channel.

Wherein the physical channel is the actual bearer of the wireless signal in the wireless network. The physical channels may include a physical downlink shared channel (physical downlink shared channel, PDSCH) and a physical uplink shared channel (physical uplink shared channel, PUSCH). The PDSCH may be used for the network device to send wireless signals to the terminal device; PUSCH may be used for a terminal device to send wireless signals to a network device.

Next, a method for allocating resources of the physical downlink shared channel will be described in further detail with reference to fig. 6 on the basis of the embodiment shown in fig. 2.

The network device may obtain downlink control information, which may be used to schedule the physical downlink shared channel.

The downlink control information may include configuration information. The configuration information may include a bitmap, or an identification of at least one VRB. For example, the configuration information may include a bitmap "110010", wherein bit 1 of the bitmap is 1, may be used to indicate the first group of PRBs, and may include PRB-0 and PRB-1; bit 2 of the bit map is 1, which may be used to indicate the 2 nd group of PRBs, may include PRB-2 and PRB-3, and so on, … …, until bit 6 is 0, which may be used to indicate the 6 th group of PRBs, may include PRB-10 and PRB-11.

S602, the network equipment sends downlink control information to the terminal equipment.

The network device may send downlink control information to the terminal device through the 5G network.

S603, the terminal equipment determines at least one PRB indicated by the configuration information as a frequency domain resource.

For example, if the configuration information includes a bitmap "110010", where bit 1 of the bitmap is 1, indicating a first group of PRBs including PRB-0 and PRB-1; bit 2 is 1, indicating a group 2 PRB, including PRB-2 and PRB-3; the 5 th bit is 1, indicating that the 5 th group of PRBs includes PRB-8 and PRB-9, the terminal device may determine PRB-0, PRB-1, PRB-2, PRB-3, PRB-8 and PRB-9 as frequency domain resources, which may be used for the terminal device to receive PDSCH.

S604, the network device transmits PDSCH to the terminal device on the frequency domain resource.

For example, if it is determined that PRB-0, PRB-1, PRB-2, PRB-3, PRB-8, and PRB-9 are frequency domain resources, the network device may transmit PDSCH to the terminal device on the 6 specified PRBs so that the terminal device receives PDSCH on the 6 specified PRBs.

In the embodiment of the application, the network equipment can acquire the downlink control information and send the downlink control information to the terminal equipment. The terminal device may determine a frequency domain resource to be used by the wireless network according to the physical resource block indicated by the configuration information in the downlink control information, and receive a physical downlink shared channel on the frequency domain resource to be used. The network device and the terminal device can communicate on the appointed frequency domain resource, and the mapping of the physical downlink shared channel to the unavailable frequency domain resource is avoided, so that the reliability of resource configuration is improved.

Next, a method for allocating resources of the physical uplink shared channel will be described in further detail with reference to fig. 7, based on the embodiment shown in fig. 2.

The network device may obtain uplink control information, which may be used to schedule the physical uplink shared channel.

The uplink control information may include configuration information of the wireless signal. The configuration information may include a bitmap, or an identification of at least one VRB. For example, the configuration information may include VRB-1 and VRB-2, where VRB-1 corresponds to PRB-1 and VRB-2 corresponds to PRB-2.

The network device may send uplink control information to the terminal device through the 5G network.

And S704, the terminal equipment sends the PUSCH to the network equipment on the frequency domain resource.

For example, if the terminal device determines PRB-1, PRB-2 as frequency domain resources, the terminal device may transmit PUSCH on the 2 specified PRBs to the network device so that the network device may receive PUSCH on the 2 specified PRBs.

In the embodiment of the application, the network equipment can acquire the uplink control information and send the uplink control information to the terminal equipment. The terminal device may determine a frequency domain resource to be used by the wireless signal according to the physical resource block indicated by the configuration information in the uplink control information, and send a physical uplink shared channel on the frequency domain resource to be used. The network device and the terminal device can communicate on the appointed frequency domain resource, and the mapping of the physical uplink shared channel to the unavailable frequency domain resource is avoided, so that the reliability of resource configuration is improved.

The resource allocation method may further include a resource allocation method for the reference signal.

Among them, the reference signals can be classified into downlink channel state information reference signals (channel state information reference signal, CSI-RS) and uplink sounding reference signals (sounding reference signal, SRS). Wherein, the CSI-RS may be used to provide a reference for downlink resource scheduling, and the SRS may be used to provide a reference for uplink resource scheduling.

The resource allocation method of the downlink channel state information reference signal is further described in detail below with reference to fig. 8 on the basis of the embodiment shown in fig. 2.

Referring to fig. 9, an operating bandwidth may be divided into a plurality of PRBs according to a frequency domain. Further, the operating bandwidth may be divided into a plurality of sub-bands, and then a plurality of PRBs may be included in each sub-band.

Referring to fig. 10A, if the configuration information indicates that the frequency domain mapping sub-band is sub-band 1 and indicates that there are 10 PRBs, the first starting PRB is PRB-2. The terminal device may determine that 15 PRBs are included in the sub-band 1 and that the starting PRB of the sub-band 1 is PRB-0, the terminal device may determine PRB-0 as the second starting PRB. Since the identity of the first starting PRB is larger than the identity of the second starting PRB, the terminal device may determine the first starting PRB, i.e. PRB-2, as the mapped starting PRB.

Case 2: and if the identification of the first starting PRB is smaller than the identification of the second starting PRB, determining the second starting PRB as the mapping starting PRB.

Fig. 10B is a schematic diagram illustrating another mapping starting PRB location according to an embodiment of the present application.

Referring to fig. 10B, if the configuration information indicates that the frequency domain mapping subband is subband 2 and there are 10 PRBs, the first starting PRB is PRB-0. The terminal device may determine that 8 PRBs are included in the sub-band 2 and that the starting PRB of the sub-band 2 is PRB-3, the terminal device may determine PRB-3 as a second starting PRB. Since the identity of the first starting PRB is smaller than the identity of the second starting PRB, the terminal device may determine the second starting PRB, i.e. PRB-3, as the mapped starting PRB.

S805, the terminal equipment determines the residual PRBs.

The terminal device may determine the remaining PRBs according to the starting PRB and the ending PRB of the frequency domain mapping subband, which may include the following 2 cases:

case 1: if the frequency domain mapping sub-band is a certain downlink sub-band, determining the rest PRB according to the mapping starting PRB and the ending PRB of the downlink sub-band.

As in fig. 10A, if the frequency domain mapped subband is subband 1 and the mapping starting PRB is PRB-2; if the ending PRB of sub-band 1 is PRB-14, the terminal device may determine PRB-2 through PRB-14 in sub-band 1 as the remaining PRB.

Case 2: if the frequency domain mapping sub-band is a plurality of downlink sub-bands, determining the rest PRB according to the mapping starting PRB and the termination PRB of the plurality of downlink sub-bands.

For example, if the frequency domain mapped subband includes subband 1 and subband 3, where the frequency domain position of subband 3 is lower than the frequency domain position of subband 1, both subband 1 and subband 3 are subbands transmitting the downlink signal. If the starting PRB to the ending PRB corresponding to the sub-band 3 are the PRB-0 to the PRB-8, the starting PRB to the ending PRB corresponding to the sub-band 1 are the PRB-20 to the PRB-31. The terminal device may determine a mapping starting PRB according to the starting PRB corresponding to the subband 3, and if it is determined that the mapping starting PRB is PRB-1, the terminal device may determine PRB-1 to PRB-8 in the subband 3 and PRB-20 to PRB-31 of the subband 1 as remaining PRBs.

S806, the terminal equipment determines frequency domain resources according to the mapping initial PRB, the residual PRB and the first quantity.

The terminal device may determine the number of PRBs used for transmitting the downlink signal from the remaining PRBs as the second number, and further may determine the frequency domain resource according to the mapping starting PRB, the second number, and the first number. Specifically, the following 4 cases may be included:

if the frequency domain mapped subband is a downlink subband, the remaining PRBs are all PRBs in the downlink subband, and case 1 and case 2 may be included, where,

Case 1: if the second number is greater than or equal to the first number, frequency domain resources may be determined in the remaining PRBs according to the mapping starting PRBs and the first number.

As in fig. 10A, if the frequency domain mapped subband indicated in the configuration information is subband 1 and 10 PRBs are indicated, the first number is 10. If the terminal device determines that the remaining PRBs of subband 1 are PRB-2 to PRB-14, where PRB-2 to PRB-14 are all used for transmitting the downlink signal, the corresponding second number is 13. Since the second number is greater than the first number, the terminal device may determine 10 PRBs of PRB-2 through PRB-11 among PRB-2 through PRB-14 of the subband 1 as frequency domain resources.

Case 2: if the second number is smaller than the first number, the remaining PRBs may be determined as frequency domain resources according to the mapping starting PRBs and the second number.

As in fig. 10B, if the frequency domain mapped subband indicated in the configuration information is subband 2 and 10 PRBs are indicated, the first number is 10. If the terminal device determines that the remaining PRBs of the subband 2 are PRB-3 to PRB-10, where all PRB-3 to PRB-10 are used for transmitting the downlink signal, the corresponding second number is 8. Since the second number is smaller than the first number, the terminal device may determine the PRBs-3 through PRB-10 in the subband 2 as frequency domain resources for a total of 8 PRBs.

If the frequency domain mapping sub-band is a plurality of downlink sub-bands, the remaining PRBs are PRBs in the plurality of downlink sub-bands, including case 3 and case 4. Next, in connection with fig. 11A to 11B, determination of frequency domain resources among a plurality of subbands will be described.

Case 3: if the second number of PRBs used for transmitting the downlink signal in the plurality of downlink sub-bands is greater than or equal to the first number, determining frequency domain resources in the remaining PRBs according to the mapping starting PRBs and the first number.

Fig. 11A is a schematic diagram illustrating determining frequency domain resources according to an embodiment of the present application. Referring to fig. 11A, if the operating bandwidth includes a subband 1, a subband 2 and a subband 3, where the subband 1 and the subband 3 are downlink subbands and the subband 2 is an uplink subband. If the configuration information indicates that the frequency domain mapping sub-band is sub-band 3 and sub-band 1, and the configuration information comprises 10 PRBs. The terminal device may determine that the remaining PRBs in the subband 3 are PRB-1 to PRB-12, where PRB-1 to PRB-12 are all used for transmitting downlink signals, and total 12 PRBs; the PRBs in sub-band 1 are determined to be PRB-20 to PRB-30, wherein each of PRB-20 to PRB-30 is used for transmitting downlink signals, and the total number of PRBs is 11. Wherein the frequency domain position of subband 3 is lower than the frequency domain position of subband 1. Although the configuration information indicates the sub-band 1 and the sub-band 3, since the PRBs for transmitting the downlink signal in the sub-band 3 are 12 and larger than the 10 PRBs indicated in the configuration information, and the frequency domain position of the sub-band 3 is lower than the frequency domain position of the sub-band 1, the terminal device may determine the total of 10 remaining PRBs as frequency domain resources from the PRB-1 to PRB-10 in the sub-band 3.

Case 4: if the second number of PRBs used for transmitting the downlink signal in the plurality of downlink sub-bands is smaller than the first number, determining the frequency domain resource in the PRBs of the plurality of downlink sub-bands according to the mapping starting PRBs and the first number.

Fig. 11B is a schematic diagram of determining a frequency domain resource according to an embodiment of the present application. Referring to fig. 11B, if the operating bandwidth includes a subband 1, a subband 2 and a subband 3, where the subband 1 and the subband 3 are downlink subbands and the subband 2 is an uplink subband. If the configuration information indicates that the frequency domain mapping sub-band is sub-band 1 and sub-band 3, and the configuration information comprises 20 PRBs; if the terminal device determines that the number of PRBs for transmitting the downlink signal in the subband 3 is 9, and the number of PRBs for transmitting the downlink signal in the subband 1 is 10, the frequency domain position of the subband 3 is lower than the frequency domain position of the subband 1. If the terminal equipment determines that the remaining PRBs in the sub-band 3 are PRB-1 to PRB-9, wherein the PRB-1 to PRB-9 are used for transmitting downlink signals, and the total number of the PRBs is 9; the PRBs in subband 1 are determined to be PRB-20 to PRB-29, where PRB-20 to PRB-29 are all used for transmitting downlink signals, and 10 PRBs total, and then the terminal device may determine PRB-1 to PRB-9 in subband 3 and PRB-20 to PRB-29 in subband 1 as frequency domain resources. Since subband 2 in the operating bandwidth is used for transmitting the uplink signal, PRBs in subband 2 are not available and during the mapping process, subband 2 may be avoided.

It should be noted that, in the embodiment of the present application, the frequency domain resource may be used for the terminal device to receive the CSI-RS.

S807, the network device sends the CSI-RS to the terminal device on the frequency domain resource.

For example, if PRB-3 to PRB-10 in subband 2 are determined to be frequency domain resources, the network device may transmit CSI-RS to the terminal device on PRB-3 to PRB-10 in subband 2, so that the terminal device receives CSI-RS on PRB-3 to PRB-10 of the subband.

In the embodiment of the present application, the network device may acquire configuration information of the wireless signal, and send the configuration information to the terminal device, where the configuration information may include an identifier of a first starting PRB in at least one PRB and a first number of at least one PRB. The terminal device may determine a second starting PRB of the frequency domain mapping sub-band according to the configuration information, and may further determine a mapping starting PRB according to the first starting PRB and the second starting PRB. The terminal device may determine a remaining PRB according to the mapping start PRB and the ending PRB of the frequency domain mapping subband, and determine a second number of PRBs for transmitting the downlink signal in the remaining PRBs, and further may determine the remaining PRB or a frequency domain resource in the remaining PRB according to the mapping start PRB, the second number, and the first number, and receive the downlink channel state information reference signal on the frequency domain resource. The network device and the terminal device can communicate on the appointed frequency domain resource, and the situation that the downlink channel state information reference signal is mapped to the unavailable frequency domain resource is avoided, so that the reliability of resource allocation is improved.
