Description

[0001] This application is a divisional application. The application number of the original application is: 201980000125.5, the application date is January 9, 2019, and the name of the invention is “Resource allocation method and device”. Technical Field

[0002] The present invention relates to the field of communication technology, and in particular to a resource allocation method and device. Background Art

[0003] Vehicle-to-Everything (V2x) refers to a new generation of information and communication technologies that connect vehicles to everything. V2x encompasses vehicle-to-vehicle (V2V), vehicle-to-pedestrian (V2P), and vehicle-to-infrastructure (V2I). Cellular-based V2x (C-V2x) effectively leverages existing base station deployments, reduces equipment costs, and meets the needs of V2X services. In C-V2x, communications between onboard devices and other devices can be relayed through base stations and the core network, leveraging the existing communication links between user devices and base stations in the cellular network. Alternatively, direct communication can be achieved through direct links (SLs) between devices.

[0004] To support the diverse needs of various V2x services and provide higher communication rates, shorter communication delays, and more reliable communication quality, the physical layer of 5G NR-based vehicle-to-vehicle (NR V2x) technology must support both unicast and multicast transmissions, as well as the physical layer hybrid automatic repeat request (HARQ) feedback mechanism for both unicast and multicast transmissions. To support physical layer HARQ for both unicast and multicast direct communication, a physical sidelink feedback channel (PSFCH) has been added to NR V2x to transmit HARQ feedback information. However, configuring PSFCH resources is a challenge that needs to be addressed. Summary of the Invention

[0096] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0097] In related technologies, in C-V2x, resource pools are configured to allocate time and frequency resources for various direct-link channels, such as the Physical Sidelink Share Channel (PSSCH) and the Physical Sidelink Control Channel (PSCCH). For example, the configuration information for the PSSCH and PSCCH resource pools may include: the time domain position of the subframes occupied by the PSSCH and PSCCH resource pools (PSSCH and PSCCH occupy the same time domain resources), the frequency domain position of the PSSCH resource pool, and the frequency domain position of the PSCCH resource pool.

[0098] However, to support physical layer HARQ for unicast and multicast direct communication, 5G NR V2x adds a PSFCH channel to transmit HARQ feedback information. Since NR V2x needs to support services that are more sensitive to latency, the PSFCH can occupy only part of the OFDM symbols in a time unit to support faster feedback. However, since the transmission and reception directions of the PSFCH, PSSCH, and PSCCH are opposite, the user equipment may need to switch between transmission and reception within the same time unit, and sufficient switching time must be reserved. In addition, since the user equipment transmitting the PSFCH is different from the user equipment transmitting the PSSCH and PSCCH, other user equipment will receive inconsistent power on different OFDM time domain symbols within the same time unit. Due to the influence of the linear range of the automatic gain control (AGC), it may take some time to adjust the AGC operating point. Even if other user equipment uses different frequency domain resources in the same time unit, the reception performance will be degraded.

[0099] In order to solve the above problems, an embodiment of the present invention provides a resource allocation method, which is applied to a user equipment, and the method includes: receiving resource allocation indication information sent by a base station or obtaining pre-configured resource allocation indication information; wherein the resource allocation indication information is used to characterize the time domain resources occupied by forward time-frequency resources and / or the time domain resources occupied by reverse time-frequency resources for direct communication within a target time unit; the forward time-frequency resources are used to transmit user data and control information, and the reverse time-frequency resources are used to transmit feedback information from a user data receiving device to a user data sending device; based on the resource allocation indication information, determining the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources. The resource allocation method provided by the embodiment of the present invention divides the direct communication time-frequency resources within a time unit into forward time-frequency resources and reverse time-frequency resources, and multiplexes them using time division multiplexing (TDM). The forward time-frequency resources are used to transmit user data and control information, and the reverse time-frequency resources are used to transmit feedback information from the user data receiving device to the user data sending device. This ensures that the device receiving on the forward time-frequency resources receives only user data and control information, while the device receiving on the reverse time-frequency resources receives only feedback information, thereby avoiding the problem of inconsistent receiving power on different time symbols during a transmission process due to inconsistent switching times between forward and reverse transmissions of different users, improving device reception performance, and enhancing service quality.

[0100] See also Figure 1 An optional application scenario of the resource allocation method in the embodiment of the present invention is shown; Figure 1The application scenario shown involves: a first device 11, a second device 12, a base station 13 of a cellular network, a base station 14, and a core network 15; wherein the cellular network can be a 4G or 5G network; the first device 11 communicates with the base station 13 through an air interface 16, and the second device 12 communicates with the base station 14 through an air interface 17; the communication between the first device 11 and the second device 12 can be transferred through the base station 13, the base station 14 and the core network 15, or can be directly communicated through a direct link 18 between the devices. Figure 1 The application scenario shown in the embodiment of the present invention is only an example of a possible application scenario of the technical solution described in the embodiment of the present invention. Other application scenarios may include Figure 1 Devices and networks not involved; in practice, the first device 11 and the second device 12 may also access the same base station.

[0101] It should be noted that the resource allocation method provided in the embodiments of the present invention can be applied to V2x technology; the user equipment involved in the embodiments of the present disclosure may, for example, include vehicle-mounted equipment, handheld devices and roadside equipment that support V2x direct communication; handheld devices may, for example, include electronic devices such as smart phones, tablet computers, desktop computers, laptop computers, drones or wearable devices (such as bracelets, smart glasses, etc.).

[0102] Based on the above analysis, the following specific embodiments are proposed.

[0103] Figure 2 FIG. 1 is a flow chart showing a resource allocation method according to an exemplary embodiment. The execution subject of the resource allocation method in the embodiment of the present invention may be a user equipment, such as Figure 2 As shown, the method includes the following steps 201-202:

[0104] In step 201, resource allocation indication information sent by a base station is received or pre-configured resource allocation indication information is obtained; wherein the resource allocation indication information is used to represent the time domain resources occupied by forward time-frequency resources and / or the time domain resources occupied by reverse time-frequency resources for direct communication within a target time unit; the forward time-frequency resources are used to transmit user data and control information, and the reverse time-frequency resources are used to transmit feedback information from a user data receiving device to a user data sending device.

[0105] For example, the feedback information may include any one of the following information or a combination thereof: HARQ feedback information, or channel state information (CSI) feedback information.

[0106] For example, the user equipment may receive resource allocation indication information sent by the base station, or the user equipment may use the resource allocation indication information in the pre-configuration. For example, the pre-configured resource allocation indication information may be stored in the user equipment, and when the user equipment is outside the coverage of the cellular network, the pre-configured system parameters and configuration information may be used for communication. Taking the user equipment receiving the resource allocation indication information sent by the base station as an example, the following description is provided: when the base station needs to allocate time and frequency resources for direct channels such as PSSCH, PSCCH, and PSFCH in direct communication, it may divide the time and frequency resources used for direct communication in the target time unit into forward time and frequency resources and reverse time and frequency resources based on the estimated time and frequency resource sizes required for user data, control information, and feedback information of the direct communication. The forward time and frequency resources and the reverse time and frequency resources are multiplexed in a time division multiplexing manner, and the forward time and frequency resources are used to transmit user data and control information, and the reverse time and frequency resources are used to transmit feedback information (such as HARQ feedback information, CSI feedback information, etc.) from the user data receiving device to the user data sending device. For example, forward time-frequency resources are allocated to the PSSCH and PSCCH for transmitting user data and control information, while reverse time-frequency resources are allocated to the PSFCH for transmitting feedback information. Optionally, the time domain resources occupied by the forward time-frequency resources within the target time unit are continuous, and the time domain resources occupied by the reverse time-frequency resources within the target time unit are also continuous.

[0107] For example, the target time unit may include any one of the following time units or a combination thereof: a frame, a subframe, a time slot, or a time domain symbol. Hereinafter, slots are used as the time unit, and symbols are used as the minimum unit for time domain resource allocation. However, the present invention does not exclude other possibilities, such as using subframes or frames as the time unit and slots as the minimum time domain resource unit for allocation.

[0108] For example, the implementation of receiving the resource allocation indication information sent by the base station in step 201 may include any one of the following methods or a combination thereof:

[0109] Method A) Receive Radio Resource Control (RRC) signaling sent by the base station; wherein the RRC signaling includes resource allocation indication information. Usually RRC configuration is semi-static or static information, and the information update interval is in minutes, hours or days.

[0110] Method B) Receive downlink control information (DCI) sent by the base station; wherein the DCI includes resource allocation indication information. Usually, DCI signaling is dynamic signaling, and the information update time interval is in milliseconds.

[0111] Optionally, the present disclosure does not limit whether the base station needs to indicate to the user equipment the frequency domain resources occupied by the forward time-frequency resources and the reverse time-frequency resources. It can be assumed that the forward time-frequency resources and the reverse time-frequency resources include all frequency domain resources, or the minimum frequency domain resource position and frequency domain resource width can be specified for the forward time-frequency resources and the reverse time-frequency resources.

[0112] For example, the resource allocation indication information may be implemented in any one of the following ways or a combination thereof:

[0113] Method a) The resource allocation indication information includes: first resource indication information and / or second resource indication information; wherein the first resource indication information is used to represent the time domain resource length of the forward time-frequency resources used for direct communication within the target time unit; the second resource indication information is used to represent the time domain resource length of the reverse time-frequency resources.

[0114] For example, in this embodiment, the time domain symbol is used as the minimum unit for time domain resource division, and the target time unit is composed of several time domain symbols. If all time domain resources within the target time unit are used for direct communication, the base station can limit the sequence number of the time domain symbol occupied by the forward time-frequency resource to be smaller than the sequence number of the time domain symbol occupied by the reverse time-frequency resource, that is, the forward time-frequency resource is limited to occupy the time domain symbol at the front position within the target time unit, and the reverse time-frequency resource occupies the time domain symbol at the back position within the target time unit; and the resource allocation indication information sent by the base station to the user equipment includes first resource indication information and / or second resource indication information, the first resource indication information is used to represent the time domain resource length of the forward time-frequency resource used for direct communication within the target time unit, that is, to indicate the time domain symbol within the target time unit occupied by the forward time-frequency resource, and the second resource indication information is used to represent the time domain resource length of the reverse time-frequency resource, that is, to indicate the time domain symbol within the target time unit occupied by the reverse time-frequency resource. The time domain symbol between the forward time-frequency resource and the reverse time-frequency resource in the target time unit can be used as a guard interval or for other purposes.

[0115] Mode b) The resource allocation indication information includes: third resource indication information and / or fourth resource indication information; wherein the third resource indication information is used to represent the starting time domain resource position and time domain resource length of the forward time-frequency resources used for direct communication within the target time unit; the fourth resource indication information is used to represent the starting time domain resource position and time domain resource length of the reverse time-frequency resources.

[0116] For example, if the target time unit contains both time domain symbols for direct communication and time domain symbols used only for uplink and downlink communication between the base station and the user equipment, the base station may include third resource indication information and / or fourth resource indication information in the resource allocation indication information sent to the user equipment. The third resource indication information is used to represent the starting time domain resource position and time domain resource length of the forward time-frequency resources used for direct communication in the target time unit, that is, to indicate the starting time domain resource position and the number of time domain symbols occupied by the forward time-frequency resources in the target time unit. The fourth resource indication information is used to represent the starting time domain resource position and time domain resource length of the reverse time-frequency resources, that is, to indicate the starting time domain resource position and the number of time domain symbols occupied by the reverse time-frequency resources in the target time unit.

[0117] Mode c) The resource allocation indication information includes: an identifier of a time domain resource allocation format, used to instruct the user equipment to determine the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources according to the time domain resource allocation format.

[0118] For example, multiple different time-domain resource allocation formats can be pre-defined in a communication protocol, each time-domain resource allocation format corresponding to a resource partitioning method for partitioning direct communication time-frequency resources within a time unit into forward time-frequency resources and reverse time-frequency resources. Each time-domain resource allocation format is assigned an identifier, such as a sequence number. Configuration information is pre-written into a static or semi-static memory of the user equipment, wherein the configuration information includes identifiers for each time-domain resource allocation format and the correspondence between different time-domain resource allocation formats and different resource partitioning methods.

[0119] The base station determines a resource partitioning method for dividing the time-frequency resources used for direct communication within a target time unit into forward time-frequency resources and reverse time-frequency resources based on the estimated physical resource sizes required for user data, control information, and feedback information of direct communication, and obtains a time domain resource allocation format corresponding to the resource partitioning method from the above configuration information. The base station then carries an identifier of the time domain resource allocation format in downlink dynamic indication signaling (e.g., DCI), and instructs the user equipment to use the resource partitioning method corresponding to the time domain resource allocation format through the identifier of the time domain resource allocation format.

[0120] In step 202, the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources are determined according to the resource allocation indication information.

[0121] The user equipment determines the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources based on the resource allocation indication information; then transmits user data and control information on the forward time-frequency resources, and transmits feedback information from the user data receiving device to the user data sending device on the reverse time-frequency resources.

[0122] For example, the time domain resources between the forward time-frequency resources and the reverse time-frequency resources can be determined as a protection interval; wherein, the time domain resources occupied by the protection interval are used to provide the user equipment with time for switching the transmission direction, thereby providing the user equipment with time for switching the transmission direction, avoiding the problem of inconsistent received power on different time symbols during a transmission process due to inconsistent forward transmission and reverse transmission switching times of different users.

[0123] By adopting the technical solution provided by the embodiment of the present invention, the direct communication time-frequency resources within a time unit are divided into forward time-frequency resources and reverse time-frequency resources, and time division multiplexing is adopted for multiplexing. Forward time-frequency resources are used to transmit user data and control information, and reverse time-frequency resources are used to transmit feedback information from the user data receiving device to the user data sending device. This can ensure that the device receiving on the forward time-frequency resources receives user data and control information, while the device receiving on the reverse time-frequency resources receives feedback information, thereby avoiding the problem of inconsistent receiving power on different time symbols during a transmission process due to inconsistent switching time of forward and reverse transmission of different users, thereby improving the receiving performance of the device and improving the service quality.

[0124] Figure 3 FIG. 1 is a flow chart showing a resource allocation method according to an exemplary embodiment. The execution subject of the resource allocation method in the embodiment of the present invention may be a base station of a cellular network, such as Figure 3 As shown, the method includes the following steps 301-302:

[0125] In step 301, the time-frequency resources used for direct communication within the target time unit are divided into forward time-frequency resources and reverse time-frequency resources of time division multiplexing; wherein, the forward time-frequency resources are used to transmit user data and control information, and the reverse time-frequency resources are used to transmit feedback information from the user data receiving device to the user data sending device.

[0126] For example, the target time unit may include any one of the following time units or a combination thereof: a frame, a subframe, a time slot, or a time domain symbol. The feedback information may include any one of the following information or a combination thereof: HARQ feedback information or CSI feedback information.

[0127] For example, when a base station needs to allocate time and frequency resources for direct channels such as PSSCH, PSCCH, and PSFCH in direct communication, it can divide the time and frequency resources used for direct communication within a target time unit into forward time and frequency resources and reverse time and frequency resources based on the estimated physical resource sizes required for user data, control information, and feedback information of the direct communication. The forward time and frequency resources and the reverse time and frequency resources are multiplexed through time division multiplexing. The forward time and frequency resources are used to transmit user data and control information, and the reverse time and frequency resources are used to transmit feedback information (such as HARQ feedback information, CSI feedback information, etc.) from a user data receiving device to a user data transmitting device. For example, the time domain resources occupied by the forward time and frequency resources are allocated to PSSCH and PSCCH for PSSCH to transmit user data and PSCCH to transmit control information, while the time domain resources occupied by the reverse time and frequency resources are allocated to PSFCH for PSFCH to transmit feedback information. Optionally, the time domain resources occupied by the forward time-frequency resources within the target time unit are continuous, and the time domain resources occupied by the reverse time-frequency resources within the target time unit are continuous.

[0128] In step 302, resource allocation indication information is sent to the user equipment; wherein the resource allocation indication information is used to represent the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources for direct communication within the target time unit.

[0129] For example, the implementation of sending the resource allocation indication information to the user equipment in step 302 may include any one of the following methods or a combination thereof:

[0130] Method 1) Sending RRC signaling to the user equipment; wherein the RRC signaling includes resource allocation indication information.

[0131] Method 2) Sending DCI to the user equipment; wherein the DCI includes resource allocation indication information.

[0132] After receiving the resource allocation indication information, the user equipment obtains the time domain resources occupied by the forward time-frequency resources and the time domain resources occupied by the reverse time-frequency resources allocated by the base station based on the resource allocation indication information; then, the user data and control information are transmitted on the forward time-frequency resources, and feedback information from the user data receiving device to the user data sending device is transmitted on the reverse time-frequency resources.

[0133] Optionally, the present disclosure does not limit whether the base station needs to indicate to the user equipment the frequency domain resources occupied by the forward time-frequency resources and the reverse time-frequency resources. It can be assumed that the forward time-frequency resources and the reverse time-frequency resources include all frequency domain resources, or the minimum frequency domain resource position and frequency domain resource width can be specified for the forward time-frequency resources and the reverse time-frequency resources.

[0134] For example, the resource allocation indication information may be implemented in any one of the following ways or a combination thereof:

[0135] Method a) The resource allocation indication information includes: first resource indication information and / or second resource indication information; wherein the first resource indication information is used to represent the time domain resource length of the forward time-frequency resources used for direct communication within the target time unit; the second resource indication information is used to represent the time domain resource length of the reverse time-frequency resources.

[0136] For example, in this embodiment, the time domain symbol is used as the minimum unit for time domain resource division to represent the time domain resource. The target time unit is composed of several time domain symbols. If all time domain symbols in the target time unit are used for direct communication, the base station can limit the sequence number of the time domain symbol occupied by the forward time-frequency resource to be less than the sequence number of the time domain symbol occupied by the reverse time-frequency resource, that is, the forward time-frequency resource is limited to occupy the time domain symbol at the front position in the target time unit, and the reverse time-frequency resource occupies the time domain symbol at the back position in the target time unit; and the resource allocation indication information sent by the base station to the user equipment includes the first resource indication information and / or the second resource indication information, the first resource indication information is used to represent the time domain resource length of the forward time-frequency resource used for direct communication in the target time unit, that is, to indicate the time domain symbol in the target time unit occupied by the forward time-frequency resource, and the second resource indication information is used to represent the time domain resource length of the reverse time-frequency resource, that is, to indicate the time domain symbol in the target time unit occupied by the reverse time-frequency resource. The time domain symbols between the forward time-frequency resources and the reverse time-frequency resources in the target time unit can be used as a guard interval or for other purposes.

[0137] Mode b) The resource allocation indication information includes: third resource indication information and / or fourth resource indication information; wherein the third resource indication information is used to represent the starting time domain resource position and time domain resource length of the forward time-frequency resources used for direct communication within the target time unit; the fourth resource indication information is used to represent the starting time domain resource position and time domain resource length of the reverse time-frequency resources.

[0138] For example, if the target time unit contains both time domain symbols for direct communication and time domain symbols used only for uplink and downlink communication between the base station and the user equipment, the base station may include third resource indication information and fourth resource indication information in the resource allocation indication information sent to the user equipment. The third resource indication information is used to represent the starting time domain resource position and time domain resource length of the forward time-frequency resources used for direct communication in the target time unit, that is, to indicate the starting time domain resource position and the number of time domain symbols occupied by the forward time-frequency resources in the target time unit. The fourth resource indication information is used to represent the starting time domain resource position and time domain resource length of the reverse time-frequency resources, that is, to indicate the starting time domain resource position and the number of time domain symbols occupied by the reverse time-frequency resources in the target time unit.

[0139] Mode c) The resource allocation indication information includes: an identifier of a time domain resource allocation format, used to instruct the user equipment to determine the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources according to the time domain resource allocation format.

[0140] For example, multiple different time-domain resource allocation formats can be pre-defined in a communication protocol, each time-domain resource allocation format corresponding to a resource partitioning method for partitioning direct communication time-frequency resources within a time unit into forward time-frequency resources and reverse time-frequency resources. Each time-domain resource allocation format is assigned an identifier, such as a sequence number. Configuration information is pre-written into a static or semi-static memory of the user equipment, wherein the configuration information includes identifiers for each time-domain resource allocation format and the correspondence between different time-domain resource allocation formats and different resource partitioning methods.

[0141] Figure 4 shows a resource partitioning method corresponding to a time domain resource allocation format, Figure 4 The resource division method corresponding to the time domain resource allocation format with sequence number n is as follows: the forward time-frequency resources occupy time domain symbols 3 to 9 within the time unit, which are used to transmit user data and control information from the data sending device to the data receiving device; while the reverse time-frequency resources occupy time domain symbols 11 and 12 within the time unit, which are used to transmit feedback information from the data receiving device to the data sending device; x represents a time domain symbol that cannot be used for direct communication. Time domain symbol x may be used for uplink and downlink communication, protection interval, or other purposes.

[0142] The base station determines a resource partitioning method for dividing the time-frequency resources used for direct communication within a target time unit into forward time-frequency resources and reverse time-frequency resources based on the estimated physical resource sizes required for user data, control information, and feedback information of direct communication, and obtains a time domain resource allocation format corresponding to the resource partitioning method from the above configuration information. The base station then carries an identifier of the time domain resource allocation format in downlink dynamic indication signaling (e.g., DCI), and instructs the user equipment to use the resource partitioning method corresponding to the time domain resource allocation format through the identifier of the time domain resource allocation format.

[0143] By adopting the technical solution provided by the embodiment of the present invention, the direct communication time-frequency resources within a time unit are divided into forward time-frequency resources and reverse time-frequency resources, and time division multiplexing is adopted for multiplexing. Forward time-frequency resources are used to transmit user data and control information, and reverse time-frequency resources are used to transmit feedback information from the user data receiving device to the user data sending device. This can ensure that the device receiving on the forward time-frequency resources receives user data and control information, while the device receiving on the reverse time-frequency resources receives feedback information, thereby avoiding the problem of inconsistent receiving power on different time symbols during a transmission process due to inconsistent switching time of forward and reverse transmission of different users, thereby improving the receiving performance of the device and improving the service quality.

[0144] Figure 5 FIG. 1 is a flow chart showing a resource allocation method according to an exemplary embodiment. In the embodiment of the present invention, the execution subject of the resource allocation method may be a base station. Figure 5 The method shown includes the following steps 501-503, wherein the parts not described in detail in this embodiment can be referred to Figure 3 Corresponding description of the embodiment:

[0145] In step 501, the time-frequency resources used for direct communication within the target time unit are divided into forward time-frequency resources and reverse time-frequency resources of time division multiplexing; wherein, the forward time-frequency resources are used to transmit user data and control information, and the reverse time-frequency resources are used to transmit feedback information from the user data receiving device to the user data sending device.

[0146] In step 502, the time domain resources between the forward time-frequency resources and the reverse time-frequency resources are determined as a guard interval; wherein the time domain resources occupied by the guard interval are used to provide time for the user equipment to switch the transmission direction.

[0147] For example, when there are no time domain resources for uplink and / or downlink communications between the forward time-frequency resources and the reverse time-frequency resources, a time domain protection interval is set between the forward time-frequency resources and the reverse time-frequency resources, and the protection interval is used to provide time for switching the transmission direction, that is, the time for switching the receiving direction and the sending direction. When the forward time-frequency resources and the reverse time-frequency resources occupy discontinuous time-frequency resources in the time domain, the time-frequency resources between the forward time-frequency resources and the reverse time-frequency resources can be used for uplink and / or downlink communications while serving as a protection interval. It should be noted that the protection interval occupies neither the forward time-frequency resources nor the reverse time-frequency resources, and the protection interval occupies the time domain symbols between the forward time-frequency resources and the reverse time-frequency resources in the target time unit. Optionally, the behavior of the user equipment within the protection interval may not be standardized. The protection interval can be configured by the base station for the user equipment, or the configuration information of the protection interval can be written into the static or semi-static memory of the user equipment in advance.

[0148] Figure 6a and Figure 6b A resource allocation method is shown. Figure 6a and Figure 6b In the scheme, the forward time-frequency resources occupy the first ten time-domain symbols in a time slot, the reverse time-frequency resources occupy the twelfth and thirteenth time-domain symbols in a time slot, and the guard interval occupies the eleventh and fourteenth time-domain symbols in a time slot; the time-domain resources occupied by the forward time-frequency resources are used to transmit user data and control information from the data sending device to the data receiving device, the time-domain resources occupied by the reverse time-frequency resources are used to transmit feedback information from the data receiving device to the data sending device, and the time-domain resources occupied by the guard interval are used to provide the user device with time to switch the transmission direction.

[0149] Figure 6c and Figure 6d Another resource allocation method is shown in Figure 6c and Figure 6d In the present invention, the forward time-frequency resources occupy the first four time domain symbols in a time slot, the reverse time-frequency resources occupy the twelfth and thirteenth time domain symbols in a time slot, the time domain symbols between the forward time-frequency resources and the reverse time-frequency resources are determined as other-purpose resources, the guard interval is included in the other-purpose resources, and the fourteenth time domain symbol is also used as the guard interval.

[0150] In step 503, resource allocation indication information is sent to the user equipment; wherein the resource allocation indication information is used to represent the time domain resources occupied by the forward time-frequency resources and / or the time domain resources occupied by the reverse time-frequency resources for direct communication within the target time unit.

[0151] The technical solution provided by the embodiment of the present invention is adopted, by dividing the direct communication time-frequency resources within a time unit into forward time-frequency resources and reverse time-frequency resources, multiplexing them using time division multiplexing, and allocating protection intervals between the forward time-frequency resources and the reverse time-frequency resources, thereby providing user equipment with time for switching the transmission direction, avoiding the problem of inconsistent receiving power on different time symbols during a transmission process due to inconsistent forward and reverse transmission switching times of different users, improving equipment reception performance, and improving service quality.
