Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for communication between a beneficiary terminal, a cooperative terminal, and a network device.
Background
When a user equipment has communication quality problems such as a large error rate or multiple retransmissions in a short time, and has available capacity with another user equipment having a short-range communication function, the user equipment can increase its communication capacity by using all or a part of the capacity of the other user equipment, thereby improving the communication quality. Wherein, the communication quality is poor due to the insufficient capability of the user equipment, and the user equipment needing to be assisted by the capability of other user equipment can be understood as a benefited terminal; in addition to its own communication requirements, the further user equipment, which also has the capability to be provided to the further user equipment, may be understood as a cooperative terminal. The capability here may be understood as the capability of transmitting information between the user equipment and the base station. Capabilities may include, but are not limited to, a number of multiple-input multiple-output layers (MIMO-LayersUL) and/or a maximum number of SRS antenna Ports (maxnumberber SRS-Ports-per resource) supported per Sounding Reference Signal (SRS) resource.
One way to implement the above-mentioned cooperative function is for the benefit terminal to request the base station to configure a cooperative terminal for the benefit terminal to assist the benefit terminal to communicate, that is, the cooperative relationship between the benefit terminal and the cooperative terminal is opaque to the base station. However, at present, the base station side does not have a corresponding flow path to support the cooperation function, so that end pipe matching is needed. The end-to-end cooperation can be understood that the beneficial terminal needs to modify the reserved field to send information to the base station to request the base station to configure the cooperative terminal, so that the existing processing flow of the base station can be changed, for example, the base station needs to add a series of mechanisms such as pairing of new user equipment, forwarding protocol stack, data joint retransmission and the like to ensure non-transparent cooperative transmission.

The beneficiary terminal 101 and the cooperative terminal 102 may be connected through a short-range communication method (e.g., within a range of several hundred meters), where the short-range communication method may be a communication method of a non-third Generation Partnership Project (3 GPP), for example, a Wi-Fi direct method, or a communication method of a 3GPP, for example, a sidlink. In other embodiments, the beneficiary terminal 101 and the cooperative terminal 102 may also be connected through a short-range communication manner, such as bluetooth, and is not limited herein.
Examples of benefit terminals 101 and collaboration terminals 102 include, but are not limited to, portable or mobile electronic devices (e.g., the cell phone shown in fig. 1), personal digital assistants, cellular phones, handheld PCs, wearable devices (e.g., smart watches, smart bracelets, etc.), portable media players, handheld devices, navigation devices, servers, network devices, graphics devices, video game devices, set-top boxes, laptop devices, virtual reality and/or augmented reality devices, internet of things devices, industrial control devices, in-vehicle infotainment devices, streaming media client devices, e-books, reading devices, POS machines, or other devices.
The base station 103 communicates with the beneficiary terminal 101 and the cooperative terminal 102 through a wireless network, for example, according to a Long Term Evolution (LTE) system, a 5G communication system, a converged system of multiple access systems, or an evolved system, so as to support communication between the beneficiary terminal 101 and the cooperative terminal 102 and a core network (e.g., a Mobility Management Entity (MME), a Serving GateWay (S-GW), and a PDN GateWay (P-GW), which are not shown in fig. 1) in the wireless network.
With respect to the communication system 100 of the present application, in the process of communicating between the beneficiary terminal 101 and the base station 103, the beneficiary terminal 101 is limited by the capability, so that the quality of transmission between the beneficiary terminal 101 and the base station 103 is poor (for example, the number of retransmissions in a short time is large, the error rate is large, and the time delay of data transmission is long), and the beneficiary terminal 101 may send a cooperation request to the cooperation terminal 102 having short-range communication with the beneficiary terminal 101. In response to the cooperation request, the cooperative terminal 102 determines whether to provide at least a portion of the capabilities to the beneficiary terminal 101, thereby enhancing the ability to transfer information between the beneficiary terminal 101 and the base station 103. If the cooperative terminal 102 does not need to communicate with the base station 103, at least a portion of the capabilities of the cooperative terminal 102 may be full capabilities; if the cooperative terminal 102 needs to communicate with the base station 103, at least a portion of the capabilities of the cooperative terminal 102 may be capabilities other than those required for its own communication.
After receiving at least a part of the capabilities from the cooperative terminal 102, the beneficiary terminal 101 integrates the capabilities of the beneficiary terminal 101 and at least a part of the capabilities from the cooperative terminal 102, resulting in integrated capabilities of the beneficiary terminal 101. For the beneficiary terminal 101, in the present embodiment, the process of integrating includes at least accumulating, for example, the capabilities of the beneficiary terminal 101 and at least a portion of the capabilities from the cooperating terminal 102. If the result of the addition is greater than or equal to the upper capability limit, the upper capability limit is sent as the integrated capability to the base station 103. If the result of the addition is less than the upper capability limit, the result of the addition is sent to the base station 103 as an integrated capability. In some embodiments, the upper capability limit may be understood as the maximum limit for the user equipment (e.g., the benefit terminal 101) to signal with the base station 103. Wherein the maximum limit of signal transmission may include a maximum limit of the number of layers of mimo (e.g. 4 layers).
According to some embodiments of the present application, the cooperative terminal 102 may determine whether at least a portion of the capabilities provided to the beneficiary terminal 101 are a portion of the capabilities or all of the capabilities. In the case where the cooperative terminal 102 does not need to communicate with the base station 103, the cooperative terminal 102 may determine that at least a portion of the capabilities provided to the beneficiary terminal 101 are full capabilities. In the case where the cooperative terminal 102 needs to communicate with the base station 103, the cooperative terminal 102 may determine at least a part of the capabilities provided to the beneficiary terminal 101 as a part of the capabilities. Those skilled in the art will appreciate that the cooperative terminal 102 may also determine whether to provide at least a portion of the capabilities to the beneficiary terminal 101 based on other circumstances. For example, the cooperative terminal may determine whether to provide capabilities to the beneficiary terminal 101, and how much to provide capabilities to the beneficiary terminal 101, according to the user's selection.
In the case where the cooperative terminal 102 provides at least a portion of the capabilities to the beneficial terminal 101, if the cooperative terminal 102 receives the excess capability returned by the beneficial terminal 101, the cooperative terminal 102 takes the excess capability returned by the beneficial terminal 101 as the integrated capability of the cooperative terminal 102, or integrates (i.e., accumulates) the excess capability returned by the beneficial terminal 101 with the remaining capability of the cooperative terminal 101 as the integrated capability of the cooperative terminal 102. Where excess capacity may be understood as not requiring a capability to benefit from the transfer of information between terminal 101 and base station 103. In some embodiments of the present application, in the case that the integrated capability of the beneficial terminal 101 (i.e., the sum of the total capability of the beneficial terminal and at least a portion of the capability provided to the beneficial terminal by the cooperative terminal) exceeds the upper limit of the capability of the beneficial terminal, the above-mentioned excess capability may include the difference between the integrated capability of the beneficial terminal 101 and the upper limit of the capability of the beneficial terminal 101.
The remaining capability may be understood as the capability remaining after the entire capability of the cooperative terminal 102 is subtracted from the capability provided by the cooperative terminal 102 to the beneficiary terminal 101. In the case that the cooperative terminal needs to communicate with the base station, the remaining capability may include the part of the capability required for the cooperative terminal 102 to communicate with the base station 103. According to some embodiments of the present application, if the cooperative terminal 102 does not receive the excess capability returned by the beneficiary terminal 101, the cooperative terminal 102 takes its remaining capability as the integrated capability of the cooperative terminal 102. That is, in the present embodiment, for the cooperative terminal 102, the integrating process at least includes subtracting, for example, the entire capability of the cooperative terminal 102 minus the capability provided by the cooperative terminal 102 to the beneficiary terminal 101.
The beneficiary terminal 101 and the cooperative terminal 102 respectively transmit the integrated capability to the base station 103, and the base station 103 respectively transmits the new parameter configuration to the beneficiary terminal 101 and the cooperative terminal 102. For example, the base station sends an RRC Connection Reconfiguration message to the beneficiating terminal 101 and the cooperative terminal 102 respectively for parameter Reconfiguration, where the parameter Reconfiguration includes, but is not limited to, Reconfiguration of SRB1 (SRB: Signaling Radio Bearers) and Radio resource configuration, and establishment of SRB2 and DRB (Data Radio Bearers ). The beneficiary terminal 101 and the cooperative terminal 102 respectively receive the parameter configuration information from the base station 103, and perform transmission and/or measurement of information with the base station 103 by using communication resources (e.g., the number of antenna ports, the number of streams of data streams) corresponding to the parameter configuration.
Since the beneficiary terminal 101 integrates the capability of the beneficiary terminal 101 with at least a part of the capability of the cooperative terminal 102 to generate an integrated capability, and the integrated capability is marked as the capability of the beneficiary terminal 101 to be transmitted to the base station 103, the base station 103 does not know that a part of the integrated capability comes from the cooperative terminal 102, and therefore, the cooperative terminal 102 is transparent to the base station 103, and in such a transparent manner, the operation of the base station side can be performed according to the existing protocol, and the cooperative transmission can be realized without adding a new field or signaling. Since the cooperative terminal 102 can decide the capability provided to the beneficial terminal 101 according to the communication situation with the base station 103, it is able to avoid affecting the communication between itself and the base station 103 due to the cooperative relationship with the beneficial terminal 101.
Fig. 2 illustrates a first diagram of a process for transmitting signals between a beneficiary terminal, a cooperative terminal, and a base station, provided in accordance with some embodiments of the present disclosure. As shown in fig. 2, the beneficiary terminal 101 includes a controller 211 and a transceiver 221. The collaboration terminal 102 includes a controller 212 and a transceiver 222. The base station 103 includes a controller 213 and a transceiver 223. The respective controllers (211, 212, and 213) of the beneficiary terminal 101, the cooperative terminal 102, and the base station 103 may include, but are not limited to, Processing circuits such as a modem, a Central Processing Unit (CPU), an Application Processor (AP), a Microprocessor (MCU), an Artificial Intelligence (AI) Processor, or a Programmable logic device (FPGA).
The modem is used for modulating information (e.g., signals/data) in a baseband frequency domain to be transmitted into analog signals capable of being transmitted through the antenna according to a protocol of 3GPP, and demodulating the analog signals received by the antenna into the baseband frequency domain information capable of being processed by a processor of a user equipment (e.g., the beneficiary terminal 101 and the cooperative terminal 102 in fig. 1). The different processing units may be separate devices or may be integrated in one or more processors. In one possible implementation, the controllers (211, 212, and 213) may run operating systems, such as Android, iOS, Windows OS, Linux, and hongmeng operating systems, among others. In other possible embodiments, the controllers (211, 212, and 213) may run specific applications. A memory may also be provided in the controllers (211, 212, and 213) for storing instructions and data.
The respective transceivers (221, 222, and 223) of the benefit terminal 101, the cooperative terminal 102, and the base station 103 are used to transmit or receive signals from the base station 103 to the base station 103 through the antenna. The transceivers (221, 222, and 223) may include, but are not limited to, Front-end Modules (FEMs) circuitry and Radio Frequency (RF) circuitry. The FEM circuitry may include an antenna and an antenna port. Wherein, for the uplink, the FEM circuit further includes a Power Amplifier (PA); for the downlink, the FEM circuit also includes a Low Noise Amplifier (LNA). The RF circuit may include a mixer circuit, an amplifier circuit, a filter circuit, and a synthesizer circuit. The RF circuit is used to down-convert a received RF signal into a baseband signal and up-convert the baseband signal into an RF signal.
As shown in step S201 in fig. 2, the beneficiary terminal 101 transmits a cooperation request to the cooperation terminal 102. For example, when the transmission quality of the beneficiary terminal 101 is poor (e.g., the number of retransmissions in a short time is large, the error rate is large, the time delay of the transmission data is long, and the Signal to Interference plus Noise Ratio (SINR) is large), the transceiver 221 of the beneficiary terminal 101 may transmit the cooperation request to the transceiver 222 of the cooperative terminal 102. The collaboration request may be implemented by modifying the Wi-Fi field. The cooperation request may include information such as identification information (e.g., ID) of the beneficiary terminal 101 and/or transmission requirement information (e.g., transmission quality threshold) of the beneficiary terminal. The beneficial terminal 101 sends the cooperation request carrying the information to the cooperative terminal 102, so that the beneficial terminal 101 can be selected from the cooperative terminals 102 with better transmission quality. For example, after the cooperative terminal 102 receives the cooperation request carrying the information, the cooperative terminal may pre-determine whether the cooperation requirement of the beneficial terminal 101 is satisfied (for example, whether the transmission quality threshold is satisfied), and if the requirement is satisfied, perform a subsequent passive or active cooperation process. In some embodiments, the beneficiary terminal 101 may send the cooperation request to the cooperative terminal 102 in a passive manner, that is, the beneficiary terminal 101 requires user intervention to send the cooperation request to the cooperative terminal 102. Reference will be made to fig. 3 to illustrate that the beneficiary terminal 101 initiates a cooperation request to the cooperative terminal 102 in a passive manner.
Fig. 3 illustrates a schematic diagram of a user interface for a benefit terminal to initiate a collaboration request provided in accordance with some embodiments of the present application. As shown in fig. 3, in a case that the current communication quality of a user equipment (i.e., the beneficiary terminal 101) is not good, the user may make a cooperation request to other user equipments (the cooperation terminal 102) by clicking a key "yes 301" on the user interface. In some embodiments, as shown in fig. 3, after the key "yes 301" is clicked, a list of available user devices (i.e., available collaboration terminals 102) capable of providing at least a portion of the capabilities to the beneficiary terminal 101, such as a cell Phone 303 (Zhangsan's Phone), a tablet 304 (Li's iPad), and glasses 305 (Wang's Glass) may be displayed below the user interface of the beneficiary terminal 101. In some embodiments, after the key "no 302" is clicked, the beneficiary terminal 101 does not make a cooperation request to other user equipment (the cooperation terminal 102), and no information is displayed below the user interface of the beneficiary terminal 101.
The available user equipment (the available cooperative terminal 102) may be understood as user equipment that has turned on the near field communication function within the distance range of the benefit terminal 101. As will be understood by those skilled in the art, the beneficiary terminal 101 may select, from a list of available user equipments (available collaboration terminals 102), a collaboration terminal 102 that transmits a collaboration request, in addition to selecting, from a list of available user equipments (available collaboration terminals 102), a user equipment (collaboration terminal 102) that has established close-range communication with the beneficiary terminal 101. Under the condition that the beneficial terminal 101 makes a cooperation request to other user equipment (the cooperation terminal 102), if a user wants to use the mobile Phone 303 (Zhangsan's Phone) as the cooperation terminal 102 in fig. 1, the user clicks the mobile Phone 303 on the user interface, and the beneficial terminal 101 sends the cooperation request to the mobile Phone 303 (the cooperation terminal 102).
Please continue to refer to fig. 2 to illustrate the remaining procedure of transmitting signals between the beneficiary terminal 101, the cooperative terminal 102 and the base station 103. As shown in step S202 in fig. 2, the cooperative terminal 102 determines to provide the full capability. After the beneficiary terminal 101 sends a cooperation request to the cell phone 303 (the cooperation terminal 102), a dialog box indicating whether the cooperation request sent by the beneficiary terminal 102 is allowed or not is displayed on the user interface of the cell phone 303 (the cooperation terminal 102).
Reference is now made to fig. 4 to illustrate whether the cooperative terminal 102 allows a cooperation request from the beneficiary terminal 101. FIG. 4 illustrates a schematic diagram of a user interface provided in accordance with some embodiments of the present application as to whether a collaboration endpoint allows collaboration requests from beneficiary endpoints. As shown in fig. 4, if the collaboration terminal 102 allows a collaboration request from the beneficial terminal 101 (Lisi's Phone), the user clicks a key "yes 401" on the user interface of the collaboration terminal 102. If the collaboration terminal 102 does not allow a collaboration request from the benefit terminal 101 (Lisi's Phone), the user clicks the key "no 402" on the user interface of the collaboration terminal 102.
In the case where the cooperative terminal 102 allows a cooperation request from the beneficiary terminal 101 (Lisi's Phone), the controller 212 of the cooperative terminal 102 may determine that the cooperative terminal 102 provides at least a portion of the capabilities as full capabilities or a portion of the capabilities. The cooperative terminal 102 may manually or automatically determine the size of at least a portion of the capabilities that the cooperative terminal 102 provides to the beneficiary terminal 101. In the case where the cooperative terminal 102 manually determines the size of at least a portion of the capabilities provided by the cooperative terminal 102 to the beneficiary terminal 101, as shown in fig. 4, the percentage of the capabilities provided to the beneficiary terminal 101 to the full capabilities of the cooperative terminal 102 can be displayed below the user interface of the cooperative terminal 102 for selection by the user. In this embodiment, since the cooperative terminal 102 does not need to communicate with the base station 103, at least a part of the capabilities provided by the cooperative terminal 102 to the beneficiary terminal 101 may be all capabilities, for example, the user clicks the key "100% 403" on the user interface of the cooperative terminal 102 in fig. 4.
In the case that the cooperative terminal 102 determines at least a part of the capabilities provided by the cooperative terminal 102 to the beneficiary terminal 101 in an automatic manner, the cooperative terminal 102 may automatically determine the size of at least a part of the capabilities provided by the cooperative terminal 102 to the beneficiary terminal 101 according to its communication requirements. Communication requirements may be understood that the cooperative terminal 102 need not communicate with the base station 103. If the cooperative terminal 102 needs to communicate with the base station 103, the communication requirement can be understood as the capacity size that the cooperative terminal 102 needs to occupy for communication with the base station 103. If the cooperative terminal 102 does not need to communicate with the base station 103, the communication demand is zero. If the cooperative terminal 102 has a communication demand with the base station 103, the cooperative terminal 102 may provide the benefit terminal 101 with a capability other than the capability required for its own communication. If the cooperative terminal 102 has no communication demand with the base station 103, the cooperative terminal 102 may provide its full capability to the beneficiary terminal 101.
In other embodiments, the beneficial terminal 101 may send the cooperation request to the cooperation terminal 102 in an active manner, for example, the beneficial terminal 101 or the base station 103 measures that the transmission quality of the beneficial terminal 101 is poor, and the beneficial terminal 101 actively sends the cooperation request to the cooperation terminal 102 having the short-range communication function. In the case where the collaboration terminal 102 does not allow a collaboration request from the beneficial terminal 101 (Lisi's Phone), for example, after the key "no 402" is clicked, no information is displayed below the screen of the collaboration terminal 102.
Please continue to refer to fig. 2 to illustrate the remaining procedure of transmitting signals between the beneficiary terminal 101, the cooperative terminal 102 and the base station 103. As shown in S203 in fig. 2, the cooperative terminal 102 transmits a response to the cooperation request to the beneficiary terminal 101. For example, clicking the key "100% 403" on the user interface of the collaboration terminal 102 in fig. 4, that is, the collaboration terminal 102 provides 100% of the capability to the benefit terminal 101, the transceiver 222 of the collaboration terminal 102 sends the response to the transceiver 221 of the benefit terminal 101, for example, the collaboration terminal 102 sends 100% of the capability Information to the transceiver 221 of the benefit terminal 101 through a short-range communication manner such as Wi-Fi direct, specifically, a specific D2D message needs to be predefined to indicate that the content carried by the message provides the capability to the collaboration terminal 102, and the sending format may be predefined to indicate different capabilities by referring to different Information Elements (IEs) predefined in the UECapabilityInformation manner in 3 GPP. The benefit terminal 101, and in particular how the cooperative terminal 102 is used for the provided capabilities, will be explained below.
As shown in step S204 in fig. 2, the beneficiary terminal 101 integrates capabilities. For example, in the case where the transceiver 221 of the beneficiary terminal 101 receives 100% of the capability provided from the cooperative terminal 102, the controller 211 of the beneficiary terminal 101 integrates the capability of the beneficiary terminal 101.
Assume that the original capabilities of the collaboration terminal 102 are:
MIMO-LayersULcollaboration terminal origin＝2Layers；
maxNumberSRS-Ports-PerResourceCollaboration terminal origin＝2ports。
The cooperative terminal 102 provides the full capability (100% capability) to the beneficiary terminal 101, then,
MIMO-LayersULcooperative terminal provisioning＝2Layers；
maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝2ports。
Assume that the original capabilities of the beneficiary terminal 101 are:
MIMO-LayersULbeneficiary terminal original＝2Layers；
maxNumberSRS-Ports-PerResourceBeneficiary terminal original＝2ports。
Then, the capabilities of the beneficiary terminal 101 and at least a portion of the capabilities from the cooperating terminal 102 are accumulated, an added result is obtained, the added result is used as an integrated capability of the beneficiary terminal 101, that is,
MIMO-LayersULbeneficial terminal integration＝MIMO-LayersULBeneficiary terminal original+MIMO-LayersULCooperative terminal provisioning＝2Layers+2Layers＝4Layers；
maxNumberSRS-Ports-PerResourceBeneficial terminal integration＝maxNumberSRS-Ports-PerResourceBeneficiary terminal original+maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝2ports+2ports＝4ports。
As shown in step S205 in fig. 2, the beneficiary terminal 101 transmits the integrated capabilities of the beneficiary terminal 101 to the base station 103. For example, the transceiver 221 of the beneficiary terminal 101 sends its integrated capabilities (summed result) as described above to the transceiver 223 of the base station 103. The ability of the benefit terminal 101 to transmit the integrated information to the base station 103 can be achieved in at least two ways: firstly, the beneficiating terminal 101 actively requests the base station 103 for updating capability through a Non-Access-Stratum (NAS) command Mobility Registration Update, the base station 103 queries the beneficiating terminal 101 capability through RRC signaling uecapabilityienquiry after receiving the NAS command, and the beneficiating terminal 101 sends capability information to the base station 103 through RRC signaling UECapabilityInformation. Secondly, the beneficial terminal 101 may trigger the base station 103 to query the capability information of the beneficial terminal 101 in a manner of logging off and then re-registering, such as Detach/Attach, Registration/Registration, and the like.
As shown in step S206 in fig. 2, the base station 103 sends a new parameter configuration to the beneficiary terminal 101. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capability (the result of the addition) of the benefit terminal 101, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 221 of the benefit terminal 101. In an embodiment, the base station 103 sends an RRC Connection Reconfiguration message to the beneficiating terminal 101 to perform parameter Reconfiguration of the beneficiating terminal 101, where the parameters include SRB1 (SRB: Signaling Radio Bearers), Radio resources, SRB2 and DRB (DRB: Radio Bearers, Data Radio Bearers), and the like. The beneficiating terminal 101 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports, the number of streams of data streams) corresponding to the parameter configuration. The new parameter configuration information is the same as the original parameter configuration information, but the specific values in one or some categories are different. For example, for the SRS included in the parameter radio resource, when the beneficiary terminal 101 is not provided by the cooperative terminal 102, the base station 103 configures only two SRS resources for measurement. And in the case of being provided by the cooperative terminal 102, the base station 103 configures four SRS resources for the beneficial terminal 101. Then, the beneficiary terminal 101 transmits signals on two of the SRS resources, and the cooperative terminal 101 transmits signals on the other two SRS resources. The base station can obtain the link conditions of the beneficial terminal 101 and the base station 103 by measuring the SRS, and can also obtain the link conditions of the cooperative terminal 102 and the base station 103.
As shown in step S207 in fig. 2, the beneficiary terminal 101 forwards the new parameter configuration sent to it by the base station to the cooperative terminal 102. In particular, the benefit terminal 101 may transmit the new parameter configuration to the transceiver 221 of the benefit terminal 101 by way of, for example, D2D.
The following describes how the beneficiary terminal 101 transmits the quadruple stream data to the base station using the capability provided by the cooperative terminal 102. When performing cooperation, the beneficiary terminal 101 generates data to be transmitted by the cooperative terminal 102, and transmits the data to the cooperative terminal 102 through, for example, a D2D link. For example, in this embodiment, the beneficial terminal 101 sends two stream data to be sent by the cooperative terminal 102 to the cooperative terminal 102, when performing cooperative transmission, the beneficial terminal 101 sends two stream data to the base station, and the cooperative terminal 102 sends two other stream data at the same time, so that the base station 103 can receive four stream data at the same time.
It should be noted that the data transmission to the base station 103 may adopt a diversity or multiplexing method. In the case of using the diversity scheme, the cooperative terminal 102 and the benefit terminal 101 transmit the same data to the base station 103. When the cooperative terminal 102 provides all the capabilities to the beneficiary terminal 101, in the first time slot, the beneficiary terminal 101 forwards the data to be sent to the base station 103 to the cooperative terminal 102 through the short-range communication mode. In the second time slot, both the cooperative terminal 102 and the beneficiary terminal 101 transmit the data to the base station. When the cooperative terminal 102 provides partial capability to the beneficiary terminal 101, in the first time slot, the beneficiary terminal 101 forwards data to be sent to the base station 103 to the cooperative terminal 102 through a short-range communication mode. In the second time slot, the benefit terminal 101 transmits the data to the base station 103, and the cooperative terminal 102 transmits the data to the base station 103 through a part of antenna ports (e.g., 2ports) provided to the benefit terminal 101. If the cooperative terminal also has data to send at this time, the remaining antenna ports (e.g., 2ports) that are not provided for the beneficiary terminal 101 may be used to send the self data to the base station 103.
In the case of using the multiplexing scheme, the cooperative terminal 102 and the benefit terminal 101 transmit different data to the base station 103. When the cooperative terminal 102 provides the full capability to the beneficiary terminal 101, the beneficiary terminal 101 divides the data to be transmitted to the base station 103 into two parts (i.e., a first part of data and a second part of data), and in a first time slot, the beneficiary terminal 101 forwards the first part of data to the cooperative terminal 102 through a short-range communication mode. In the second time slot, the cooperative terminal 102 transmits the first part of data to the base station 103, and the beneficiary terminal 101 transmits the second part of data to the base station 103. When the cooperative terminal 102 provides partial capability to the beneficiary terminal 101, the beneficiary terminal 101 divides the data to be transmitted to the base station 103 into two parts (i.e. a first part of data and a second part of data), and in a first time slot, the beneficiary terminal 101 forwards the first part of data to the cooperative terminal 102 through a short-range communication mode. In the second time slot, the cooperative terminal 102 transmits the first part of data to the base station 103 through a part of antenna ports (e.g., 2ports) provided to the benefit terminal 101, and the benefit terminal 101 transmits the second part of data to the base station 103. If the cooperative terminal 102 also has data to send at this time, the remaining antenna ports (e.g., 2ports) that are not provided for the benefit terminal may be used to send self data to the base station 103.
In this embodiment, since the beneficiary terminal 101 receives at least a portion of the full capability (100% capability) from the cooperative terminal 102, the capability of the beneficiary terminal 101 (e.g., MIMO-LayersUL and maxnumberber srs-Ports-PerResource) may be doubled, enabling the beneficiary terminal 101 to support a greater MIMO capability.
Fig. 5 illustrates a second diagram of a process for transmitting signals between a beneficiary terminal, a cooperative terminal, and a base station, provided in accordance with some embodiments of the present disclosure. As shown in fig. 5, the beneficiary terminal 101 includes a controller 211 and a transceiver 221. The collaboration terminal 102 includes a controller 212 and a transceiver 222. The base station 103 includes a controller 213 and a transceiver 223. For the description of the controllers (211, 221, 231) and the transceivers (212, 222, 223), reference is made to the related description in fig. 2, and the description thereof is omitted here.
As shown in step S501 in fig. 5, the beneficiary terminal 101 transmits a cooperation request to the cooperation terminal 102. For example, in the case that the transmission quality of the beneficiary terminal 101 is poor (e.g., the number of retransmissions in a short time is large, the error rate is large, and the time delay for transmitting data is long), the transceiver 221 of the beneficiary terminal 101 may transmit the cooperation request to the transceiver 222 of the cooperative terminal 102. The collaboration request may be implemented by modifying a Wi-Fi field, for example, a private standard form may be adopted, some reserved fields in a Wi-Fi beacon frame are defined as a collaboration request function, and after receiving the Wi-Fi beacon frame, a device supporting the private standard, for example, the collaboration terminal 102, determines that the device is a collaboration request by identifying the content of the reserved fields. In some embodiments, the way in which the beneficiary terminal 101 sends the cooperation request to the cooperative terminal 102 may be a passive way (e.g., like bluetooth pairing). For how the beneficiary terminal 101 sends the cooperation request to the cooperative terminal 102 in a passive manner, please refer to fig. 3 and the related description thereof, which are not described herein again. In other embodiments, the way in which the beneficiary terminal 101 sends the cooperation request to the cooperation terminal 102 may be an active way, for example, the beneficiary terminal 101 or the base station 103 measures that the transmission quality of the beneficiary terminal 101 is poor, and the beneficiary terminal 101 actively sends the cooperation request to the cooperation terminal 102 having the short-range communication function.
As shown in step S502 in fig. 5, the cooperative terminal 102 determines to provide the full capability. After the beneficiary terminal 101 sends a cooperation request to the cell phone 303 (the cooperation terminal 102), a dialog box indicating whether the cooperation request sent by the beneficiary terminal 102 is allowed or not is displayed on the user interface of the cell phone 303 (the cooperation terminal 102). In the case where the cooperative terminal 102 allows a cooperation request from the beneficiary terminal 101, the controller 212 of the cooperative terminal 102 may determine at least a portion of the capabilities provided to the beneficiary terminal 101 to be full capabilities or partial capabilities. The cooperative terminal 102 may determine the capabilities that the cooperative terminal 102 provides to the beneficiary terminal 101 in a manual or automatic manner. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in a manual manner, please refer to fig. 4 and the related description thereof, which are not repeated herein. In this embodiment, since the cooperative terminal 102 does not need to communicate with the base station 103, at least a part of the capabilities provided by the cooperative terminal 102 to the beneficiary terminal 101 may be all capabilities, for example, the user clicks the key "100% 403" on the user interface of the cooperative terminal 102 in fig. 4. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in an automatic manner, please refer to fig. 2 and the related description thereof, which are not repeated herein.
As shown in step S503 in fig. 5, the cooperative terminal 102 transmits a response to the cooperation request to the beneficiary terminal 101. For example, clicking the key "100% 403" on the user interface of the collaboration terminal 102 in fig. 4, that is, the collaboration terminal 102 provides 100% of the capability to the benefit terminal 101, the transceiver 222 of the collaboration terminal 102 transmits the response to the transceiver 221 of the benefit terminal 101, for example, the collaboration terminal 102 transmits 100% of the capability information to the transceiver 221 of the benefit terminal 101 through a short-range communication manner such as Wi-Fi direct.
As shown in step S504 in fig. 5, the beneficiary terminal 101 integrates capabilities. For example, in the case where the transceiver 221 of the beneficiary terminal 101 receives 100% of the capability provided from the cooperative terminal 102, the controller 211 of the beneficiary terminal 101 integrates the capability of the beneficiary terminal 101.
Assume that the original capabilities of the collaboration terminal 102 are:
MIMO-LayersULcollaboration terminal origin＝4Layers；
maxNumberSRS-Ports-PerResourceCollaboration terminal origin＝4ports。
The cooperative terminal 102 provides 100% of the capability to the beneficiary terminal 101, then,
MIMO-LayersULcooperative terminal provisioning＝4*100％Layers＝4Layers；
maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝4*100％ports＝4ports。
Assume that the original capabilities of the beneficiary terminal 101 are:
MIMO-LayersULbeneficiary terminal original＝2Layers；
maxNumberSRS-Ports-PerResourceBeneficiary terminal original＝2ports。
Due to MIMO-LayersULBeneficiary terminal original+MIMO-LayersULCooperative terminal provisioning＝2Layers+4Layers＝6Layers；
maxNumberSRS-Ports-PerResourceBeneficiary terminal original+maxNumberSRS-Ports-PerResourceCooperative terminal provisioningSince the UE capability information elements of the 3GPP protocol specifies various upper capability limits that can be reported by the terminal, for example, the uplink supports maximum 4-stream transmission, the capability of the beneficial terminal 101 plus 100% of the capability provided by the cooperative terminal 102 exceeds the upper capability limit, then the beneficial terminal 101 takes the upper capability limit as the integrated capability of the beneficial terminal 101, that is,
MIMO-LayersULbeneficial terminal integration＝4Layers；
maxNumberSRS-Ports-PerResourceBeneficial terminal integration＝4ports。
As shown in step S505 in fig. 5, the beneficiary terminal 101 returns the excess capacity to the cooperative terminal 102, for example, the controller 211 of the beneficiary terminal 101 calculates the excess capacity, and the excess capacity is transmitted to the transceiver 222 of the cooperative terminal 102 by the transceiver 221 of the beneficiary terminal 101. The specific calculation of excess capacity is as follows:
MIMO-LayersULexcess capacity＝MIMO-LayersULBeneficiary terminal original+MIMO-LayersULCooperative terminal provisioning-MIMO-LayersULUpper limit of capacity＝2Layers+4Layers-4 Layers＝2Layers；
maxNumberSRS-Ports-PerResourcExcess capacity＝maxNumberSRS-Ports-PerResourcBeneficiary terminal original+maxNumberSRS-Ports-PerResourcCooperative terminal provisioning-maxNumberSRS-Ports-PerResourcUpper limit of capacity＝2ports+4ports-4ports＝2ports。
As shown in step S507 in fig. 5, the beneficiary terminal 101 transmits the integrated capabilities of the beneficiary terminal 101 to the base station 103. For example, the transceiver 221 of the beneficiary terminal 101 transmits its integrated capabilities (upper capability limit) to the transceiver 223 of the base station 103. The ability of the benefit terminal 101 to transmit the integrated information to the base station 103 is in two ways: firstly, the beneficial terminal 101 actively requests the base station 103 for updating capability through the NAS command Mobility Registration Update, the base station 103 queries the capability of the beneficial terminal 101 through RRC signaling uecapabilityienquiry after receiving the NAS command, and the beneficial terminal 101 sends capability information to the base station 103 through RRC signaling UECapabilityInformation. Secondly, the beneficial terminal 101 may trigger the base station 103 to query the capability information of the beneficial terminal 101 in a manner of logging off and then re-registering, such as Detach/Attach, Registration/Registration, and the like.
As shown in step S508 in fig. 5, the base station 103 sends a new parameter configuration to the beneficiary terminal 101. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capability (capability upper limit) of the benefit terminal 101, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 221 of the benefit terminal 101. The beneficiating terminal 101 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports, the number of streams of data streams) corresponding to the parameter configuration.
In this embodiment, since the beneficiary terminal 101 receives at least a portion of the full capability (100% capability) from the cooperative terminal 102, the capability of the beneficiary terminal 101 (e.g., MIMO-LayersUL and maxnumberber srs-Ports-per resource) is doubled even though the beneficiary terminal 101 returns the cooperative terminal 102 beyond the capability, so that the beneficiary terminal 101 can support a larger MIMO capability.
As shown in step S506 in fig. 5, the cooperative terminal 102 integrates the capabilities. For example, the transceiver 222 of the cooperative terminal 102 receives the excess capacity transmitted from the transceiver 221 of the beneficiary terminal 102, and the controller 212 of the cooperative terminal 102 performs capacity integration. The process of the cooperative terminal 102 integration at least includes subtracting the capability of the cooperative terminal 102 to the beneficiary terminal 101 from the capability of the cooperative terminal 102, and adding the excess capability returned to the cooperative terminal 102 by the beneficiary terminal 101, that is,
MIMO-LayersULcollaborative terminal integration＝MIMO-LayersULCollaboration terminal origin-MIMO-LayersULCooperative terminal provisioning+MIMO-LayersULExcess capacity＝4Layers-4 Layers+2Layers＝2Layers；
maxNumberSRS-Ports-PerResourceCollaborative terminal integration＝maxNumberSRS-Ports-PerResourceCollaboration terminal origin-maxNumberSRS-Ports-PerResourceCooperative terminal provisioning+maxNumberSRS-Ports-PerResourceExcess capacity＝4ports-4ports+2ports＝2ports；
As shown in step S509 in fig. 5, the beneficiary terminal 101 forwards the new parameter configuration sent to it by the base station to the cooperative terminal 102. In particular, the benefit terminal 101 may transmit the new parameter configuration to the transceiver 221 of the benefit terminal 101 by way of, for example, D2D.
As shown in step S510 in fig. 5, the cooperative terminal 102 transmits the integrated capability of the cooperative terminal 102 to the base station 103. For example, the transceiver 222 of the cooperative terminal 102 transmits the integrated capability (excess capability) of the cooperative terminal 102 to the transceiver 223 of the base station 103.
As shown in step S511 in fig. 5, the base station 103 transmits the new parameter configuration to the cooperative terminal 102. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capability (excess capability) of the cooperative terminal 102, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 222 of the cooperative terminal 102. The cooperative terminal 102 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports and the number of streams of data streams) corresponding to the parameter configuration.
In this embodiment, although the capability provided by the cooperative terminal 102 to the beneficial terminal 101 is 100% of the capability, since the beneficial terminal 101 returns the cooperative terminal 102 to the excess capability, if the cooperative terminal 102 has a communication demand with the base station 103 later, the cooperative terminal 102 may utilize the excess capability to transmit with the base station 103 without affecting the cooperative relationship with the beneficial terminal 101.
Fig. 6 illustrates a third diagram of a procedure for transmitting signals between a beneficiary terminal, a cooperative terminal, and a base station, provided in accordance with some embodiments of the present disclosure. For the description of the beneficiary terminal 101 and the cooperative terminal 102, reference is made to the related description in fig. 2, and details are not repeated here.
As shown in step S601 in fig. 6, the beneficiary terminal 101 transmits a cooperation request to the cooperative terminal 102. For details of sending the collaboration request, refer to the related description in fig. 2 and fig. 3, which is not described herein again.
As shown in step S602 in fig. 6, the cooperative terminal 102 determines to provide part of the capability to the beneficiary terminal 101. After the beneficiary terminal 101 sends a cooperation request to the cell phone 303 (the cooperation terminal 102), a dialog box indicating whether the cooperation request sent by the beneficiary terminal 102 is allowed or not is displayed on the user interface of the cell phone 303 (the cooperation terminal 102). In the case where the cooperative terminal 102 allows a cooperation request from the beneficiary terminal 101, the controller 212 of the cooperative terminal 102 may determine to provide the capabilities of the beneficiary terminal 101 as all or a portion of the capabilities. The cooperative terminal 102 may determine the capabilities that the cooperative terminal 102 provides to the beneficiary terminal 101 in a manual or automatic manner. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in a manual manner, please refer to fig. 4 and the related description thereof, which are not repeated herein. In this embodiment, since the cooperative terminal 102 needs to communicate with the base station 103, at least a part of the capabilities provided by the cooperative terminal 102 to the beneficiary terminal 101 may be part of the capabilities, for example, the user clicks the key "50% 405" on the user interface of the cooperative terminal 102 in fig. 4. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in an automatic manner, please refer to fig. 2 and the related description thereof, which are not repeated herein.
As shown in S603 in fig. 6, the cooperative terminal 102 transmits a response to the cooperation request to the beneficiary terminal 101. For example, clicking the key "50% 405" on the user interface of the collaboration terminal 102 in fig. 4, that is, the collaboration terminal 102 provides 50% of the capability to the benefit terminal 101, the transceiver 222 of the collaboration terminal 102 transmits the response to the transceiver 221 of the benefit terminal 101, for example, the collaboration terminal 102 transmits 50% of the capability information to the transceiver 221 of the benefit terminal 101 through a short-range communication manner such as Wi-Fi direct.
As shown in step S604 in fig. 6, the beneficiary terminal 101 integrates capabilities. For example, in the case where the transceiver 221 of the beneficiary terminal 101 receives 50% of the capability provided from the cooperative terminal 102, the controller 211 of the beneficiary terminal 101 integrates the capability of the beneficiary terminal 101.
Assume that the original capabilities of the collaboration terminal 102 are:
MIMO-LayersULcollaboration terminal origin＝4Layers；
maxNumberSRS-Ports-PerResourceCollaboration terminal origin＝4ports。
The cooperative terminal 102 provides 50% of the capability to the beneficiary terminal 101, then,
MIMO-LayersULcooperative terminal provisioning＝4*50％Layers＝2Layers；
maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝4*50％ports＝2ports。
Assume that the original capabilities of the beneficiary terminal 101 are:
MIMO-LayersULbeneficiary terminal original＝2Layers；
maxNumberSRS-Ports-PerResourceBeneficiary terminal original＝2ports。
Then, the capabilities of the beneficiary terminal 101 and the capabilities from the cooperating terminal 102 are accumulated, the result of the addition is obtained, the result of the addition is taken as the integrated capability of the beneficiary terminal 101, that is,
MIMO-LayersULbeneficial terminal integration＝MIMO-LayersULBeneficiary terminal original+MIMO-LayersULCooperative terminal provisioning＝2Layers+2Layers＝4Layers；
maxNumberSRS-Ports-PerResourceBeneficial terminal integration＝maxNumberSRS-Ports-PerResourceBeneficiary terminal original+maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝2ports+2ports＝4ports。
As shown in step S605 in fig. 6, the beneficiary terminal 101 transmits the integrated capabilities of the beneficiary terminal 101 to the base station 103. For example, the transceiver 221 of the beneficiary terminal 101 sends its integrated capabilities (the result of the addition) to the transceiver 223 of the base station 103. The ability of the benefit terminal 101 to transmit the integrated information to the base station 103 is in two ways: firstly, the beneficial terminal 101 actively requests the base station 103 for updating capability through the NAS command Mobility Registration Update, the base station 103 queries the capability of the beneficial terminal 101 through RRC signaling uecapabilityienquiry after receiving the NAS command, and the beneficial terminal 101 sends capability information to the base station 103 through RRC signaling UECapabilityInformation. Secondly, the beneficial terminal 101 may trigger the base station 103 to query the capability information of the beneficial terminal 101 in a manner of logging off and then re-registering, such as Detach/Attach, Registration/Registration, and the like.
As shown in step S606 in fig. 6, the base station 103 sends a new parameter configuration to the beneficiary terminal 101. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capability (the result of the addition) of the benefit terminal 101, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 221 of the benefit terminal 101. The beneficiating terminal 101 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports, the number of streams of data streams) corresponding to the parameter configuration.
In this embodiment, since the ability of the beneficial terminal 101 to accept signals from the cooperative terminal 102 is partial (50% ability), the ability of the beneficial terminal 101 (e.g., MIMO-LayersUL and maxnumberber srs-Ports-PerResource) is doubled, thereby enabling the beneficial terminal 101 to support a larger MIMO capability.
As shown in step S607 in fig. 6, the cooperative terminal 102 integrates the capabilities, for example, the controller 212 of the cooperative terminal 102 integrates the capabilities. The process of the cooperative terminal 102 integration at least includes subtracting the capability of the cooperative terminal 102 from the capability of the cooperative terminal 102 provided to the beneficiary terminal 101, and adding the excess capability returned by the beneficiary terminal 101 to the cooperative terminal 102. Since, in the present embodiment, the excess capacity is zero, that is,
MIMO-LayersULcollaborative terminal integration＝MIMO-LayersULCollaboration terminal origin-MIMO-LayersULCooperative terminal provisioning＝4Layers-4*50％Layers＝2Layers；
maxNumberSRS-Ports-PerResourceCollaborative terminal integration＝maxNumberSRS-Ports-PerResourceCollaboration terminal origin-maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝4ports-4*50％ports＝2ports；
As shown in step S608 in fig. 6, the beneficiary terminal 101 forwards the new parameter configuration sent to it by the base station to the cooperative terminal 102. In particular, the benefit terminal 101 may transmit the new parameter configuration to the transceiver 221 of the benefit terminal 101 by way of, for example, D2D.
As shown in step S609 in fig. 6, the cooperative terminal 102 transmits the integrated capability of the cooperative terminal 102 to the base station 103. For example, the transceiver 222 of the cooperative terminal 102 transmits the integrated capability (remaining capability) of the cooperative terminal 102 to the transceiver 223 of the base station 103.
As shown in step S610 in fig. 6, the base station 103 sends a new parameter configuration to the cooperative terminal 102. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capability (remaining capability) of the cooperative terminal 102, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 222 of the cooperative terminal 102. The cooperative terminal 102 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports and the number of streams of data streams) corresponding to the parameter configuration.
In this embodiment, since the cooperative terminal 102 only provides a part of the capability to the benefit terminal 101, the cooperative terminal 102 still has the remaining capability (50% of the capability), and if the cooperative terminal 102 currently or later has a communication demand with the base station 103, the cooperative terminal 102 can use the remaining capability to transmit with the base station 103 without affecting the cooperative relationship with the benefit terminal 101. For example, the beneficiary terminal 101 only needs to use part of the rf antenna function of the cooperative terminal 102, and the cooperative terminal 102 may modulate its own data using the baseband and then transmit the data to the base station 103 using the remaining rf antenna function.
Fig. 7 illustrates a fourth diagram of a procedure for transmitting signals between a beneficiary terminal, a cooperative terminal, and a base station, provided in accordance with some embodiments of the present disclosure. For the description of the beneficiary terminal 101 and the cooperative terminal 102, reference is made to the related description in fig. 2, and details are not repeated here.
As shown in step S701 in fig. 7, the beneficiary terminal 101 transmits a cooperation request to the cooperative terminal 102. For details of sending the collaboration request, refer to the related description in fig. 2 and fig. 3, which is not described herein again.
As shown in step S702 in fig. 7, the cooperative terminal 102 determines to provide part of the capability to the beneficiary terminal 101. After the beneficiary terminal 101 sends a cooperation request to the cell phone 303 (the cooperation terminal 102), a dialog box indicating whether the cooperation request sent by the beneficiary terminal 102 is allowed or not is displayed on the user interface of the cell phone 303 (the cooperation terminal 102). In the case where the cooperative terminal 102 allows a cooperation request from the beneficiary terminal 101, the controller 212 of the cooperative terminal 102 may determine to provide all or part of the capabilities to the beneficiary terminal 101. The cooperative terminal 102 may determine the capabilities that the cooperative terminal 102 provides to the beneficiary terminal 101 in a manual or automatic manner. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in a manual manner, please refer to fig. 4 and the related description thereof, which are not repeated herein. In this embodiment, since the cooperative terminal 102 itself needs to communicate with the base station 103, that is, the cooperative terminal 102 itself has a communication requirement with the base station 103, at least a part of the capability provided by the cooperative terminal 102 to the beneficial terminal 101 may be a partial capability, for example, the user clicks the key "50% 405" on the user interface of the cooperative terminal 102 in fig. 4. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in an automatic manner, please refer to fig. 2 and the related description thereof, which are not repeated herein.
As shown in S703 in fig. 7, the cooperative terminal 102 transmits a response to the cooperation request to the beneficiary terminal 101. For example, clicking the key "50% 405" on the user interface of the collaboration terminal 102 in fig. 4, that is, the collaboration terminal 102 provides 50% of the capability to the benefit terminal 101, the transceiver 222 of the collaboration terminal 102 transmits the response to the transceiver 221 of the benefit terminal 101, for example, the collaboration terminal 102 transmits 50% of the capability information to the transceiver 221 of the benefit terminal 101 through a short-range communication manner such as Wi-Fi direct.
As shown in step S704 in fig. 7, the beneficiary terminal 101 integrates capabilities. For example, in the case where the transceiver 221 of the beneficiary terminal 101 receives 50% of the capability provided from the cooperative terminal 102, the controller 211 of the beneficiary terminal 101 integrates the capability of the beneficiary terminal 101.
Assume that the original capabilities of the collaboration terminal 102 are:
MIMO-LayersULcollaboration terminal origin＝4Layers；
maxNumberSRS-Ports-PerResourceCollaboration terminal origin＝4ports。
The cooperative terminal 102 provides 50% of the capability to the beneficiary terminal 101, then,
MIMO-LayersULcooperative terminal provisioning＝4*50％Layers＝2Layers；
maxNumberSRS-Ports-PerResourceCooperative terminal provisioning＝4*50％ports＝2ports。
Assume that the original capabilities of the beneficiary terminal 101 are:
MIMO-LayersULbeneficiary terminal original＝3Layers；
maxNumberSRS-Ports-PerResourceBeneficiary terminal original＝3ports。
Due to MIMO-LayersULBeneficiary terminal original+MIMO-LayersULCooperative terminal provisioning＝2Layers+3Layers＝5Layers；
maxNumberSRS-Ports-PerResourceBeneficiary terminal original+maxNumberSRS-Ports-PerResourceCooperative terminal provisioning2ports +3ports 5ports and the uplink supports 4-stream maximum, the capability of the beneficial terminal 101 plus 50% of the capability provided by the cooperative terminal 102 exceeds the upper capability limit, and therefore, the beneficial terminal 101 takes the upper capability limit as the integrated capability of the beneficial terminal 101, i.e.,
MIMO-LayersULbeneficial terminal integration＝4Layers；
maxNumberSRS-Ports-PerResourceBeneficial terminal integration＝4ports。
As shown in step S705 in fig. 7, the beneficiary terminal 101 transmits the integrated capabilities of the beneficiary terminal 101 to the base station 103. For example, the transceiver 221 of the beneficiary terminal 101 transmits its integrated capabilities (upper capability limit) to the transceiver 223 of the base station 103. The ability of the benefit terminal 101 to transmit the integrated information to the base station 103 is in two ways: firstly, the beneficial terminal 101 actively requests the base station 103 for updating capability through the NAS command Mobility Registration Update, the base station 103 queries the capability of the beneficial terminal 101 through RRC signaling uecapabilityienquiry after receiving the NAS command, and the beneficial terminal 101 sends capability information to the base station 103 through RRC signaling UECapabilityInformation. Secondly, the beneficial terminal 101 may trigger the base station 103 to query the capability information of the beneficial terminal 101 in a manner of logging off and then re-registering, such as Detach/Attach, Registration/Registration, and the like.
As shown in step S706 in fig. 7, the base station 103 sends a new parameter configuration to the beneficiary terminal 101. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capability (capability upper limit) of the benefit terminal 101, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 221 of the benefit terminal 101. The beneficiating terminal 101 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports, the number of streams of data streams) corresponding to the parameter configuration.
In this embodiment, since the beneficiary terminal 101 accepts at least a portion of the capability from the cooperative terminal 102 as partial capability (50% of the capability), the capability of the beneficiary terminal 101 (e.g., MIMO-LayersUL and maxnumberber srs-Ports-per resource) is increased even though the beneficiary terminal 101 returns the cooperative terminal 102 beyond the capability, so that the beneficiary terminal 101 can support a larger MIMO capability.
As shown in step S707 in fig. 7, the beneficiary terminal 101 returns the excess capability to the cooperative terminal 102. For example, the controller 211 of the benefit terminal 101 calculates the excess capacity, the excess capacity is sent by the transceiver 221 of the benefit terminal 101 to the transceiver 222 of the cooperative terminal 102, e.g., the benefit terminal 101 sends a specific message to the cooperative terminal 102 over the D2D link, with various fields within the message representing various capabilities in a predefined manner. The specific calculation of excess capacity is as follows:
MIMO-LayersULexcess capacity＝MIMO-LayersULBeneficiary terminal original+MIMO-LayersULCooperative terminal provisioning-MIMO-LayersULUpper limit of capacity＝3Layers+4*50％Layers-4 Layers＝1Layers；
maxNumberSRS-Ports-PerResourceExcess capacity＝maxNumberSRS-Ports-PerResourceBeneficiary terminal original+maxNumberSRS-Ports-PerResourceCooperative terminal provisioning-maxNumberSRS-Ports-PerResourceUpper limit of capacity＝3ports+4*50％ports-4ports＝1ports
As shown in step S708 in fig. 7, the cooperative terminal 102 integrates the capabilities. For example, the transceiver 222 of the cooperative terminal 102 receives the excess capacity transmitted from the transceiver 221 of the beneficiary terminal 102, and the controller 212 of the cooperative terminal 102 performs capacity integration. The process of the cooperative terminal 102 integration at least includes subtracting the capability of the cooperative terminal 102 to the beneficiary terminal 101 from the capability of the cooperative terminal 102, and adding the excess capability returned to the cooperative terminal 102 by the beneficiary terminal 101, that is,
MIMO-LayersULcollaborative terminal integration＝MIMO-LayersULCollaboration terminal origin-MIMO-LayersULCooperative terminal provisioning+MIMO-LayersULExcess capacity＝4Layers-4*50％Layers+1Layers＝3Layers；
maxNumberSRS-Ports-PerResourceCollaborative terminal integration＝maxNumberSRS-Ports-PerResourceCollaboration terminal origin-maxNumberSRS-Ports-PerResourceCooperative terminal provisioning+maxNumberSRS-Ports-PerResourceExcess capacity＝4ports-4*50％ports+1ports＝3ports；
As shown in step S709 in fig. 7, the beneficiary terminal 101 forwards the new parameter configuration sent to it by the base station to the cooperative terminal 102. In particular, the benefit terminal 101 may transmit the new parameter configuration to the transceiver 221 of the benefit terminal 101 by way of, for example, D2D.
As shown in step S710 in fig. 7, the cooperative terminal 102 transmits the integrated capability of the cooperative terminal 102 to the base station 103. For example, the transceiver 222 of the cooperative terminal 102 transmits the integrated capability (remaining capability + excess capability) of the cooperative terminal 102 to the transceiver 223 of the base station 103.
As shown in step S711 in fig. 7, the base station 103 transmits the new parameter configuration to the cooperative terminal 102. For example, the controller 213 of the base station 103 performs a new parameter configuration on the integrated capabilities of the cooperative terminal 102, and the transceiver 223 of the base station transmits the new parameter configuration to the transceiver 222 of the cooperative terminal 102. The cooperative terminal 102 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using communication resources (e.g., the number of antenna ports and the number of streams of data streams) corresponding to the parameter configuration.
In this embodiment, since the beneficiary terminal 101 returns the excess capability of the cooperative terminal 102 and the cooperative terminal 102 retains the remaining capability (50% of the capability), if the cooperative terminal 102 and the base station 103 have a communication requirement, the cooperative terminal 102 may transmit with the base station 103 by using the excess capability and the remaining capability without affecting the cooperative relationship with the beneficiary terminal 101.
Fig. 8 illustrates a method for benefiting from the increased capability of terminals to communicate information with a base station provided in accordance with some embodiments of the present application.
As shown in block 801 in fig. 8, the quality of the information transmitted between the beneficial terminal 101 and the base station 103 is obtained. The quality of the information transmitted between the benefit terminal 101 and the base station 103 may be measured by the benefit terminal 101 or by the base station 103. For example, the controller 211 of the benefit terminal 101 measures the quality (e.g., bit error rate, retransmission rate, transmission delay) of the information transmitted between the benefit terminal 101 and the base station 103, or the controller 213 of the base station 103 measures the quality (e.g., bit error rate, retransmission rate, transmission delay) of the information transmitted between the benefit terminal 101 and the base station 103, and then transmits the measured quality of the information transmitted between the benefit terminal 101 and the base station 103 to the transceiver 221 of the benefit terminal 101 by the transceiver 223 of the base station 103.
As shown in block 802 of fig. 8, it is determined whether the quality of the information transmitted between the beneficiary terminal 101 and the base station 103 is below a quality threshold. The quality of the information transmitted between the benefit terminal 101 and the base station 103 may be determined by the controller 211 of the benefit terminal 101. The quality threshold may comprise one or more of a bit error rate threshold, a retransmission rate threshold, and a delay threshold. If the quality of the information transmitted between the beneficial terminal 101 and the base station 103 is higher than or equal to the quality threshold, the quality of the information transmitted between the beneficial terminal 101 and the base station 103 is better; the quality of the transmission information between the benefit terminal 101 and the base station 103 is poor if the quality of the transmission information between the benefit terminal 101 and the base station 103 is below the quality threshold.
As shown in block 803 in fig. 8, if the quality of the transmission information between the beneficiary terminal 101 and the base station 103 is below the quality threshold, the beneficiary terminal 101 sends a cooperation request to the cooperating terminal 102. For example, if the controller 211 of the beneficiary terminal 101 determines that the quality of the information transmitted between the beneficiary terminal 101 and the base station 103 is below the quality threshold, then the transceiver 221 of the beneficiary terminal 101 transmits a cooperation request to the transceiver 222 of the cooperative terminal 102. The collaboration request may be implemented by modifying the Wi-Fi field. In some embodiments, the way in which the beneficiary terminal 101 sends the cooperation request to the cooperative terminal 102 may be a passive way (e.g., like bluetooth pairing). For how the beneficiary terminal 101 sends the cooperation request to the cooperative terminal 102 in a passive manner, please refer to fig. 3 and the related description thereof, which are not described herein again. In other embodiments, the way in which the beneficiary terminal 101 sends the cooperation request to the cooperation terminal 102 may be an active way, for example, the beneficiary terminal 101 or the base station 103 measures that the transmission quality of the beneficiary terminal 101 is poor, and the beneficiary terminal 101 actively sends the cooperation request to the cooperation terminal 102 having the short-range communication function.
As shown at block 804 in fig. 8, a response to the collaboration request is received from the collaboration terminal 102. For example, the transceiver 211 of the beneficiary terminal 101 receives a response to the cooperation request from the cooperative terminal 102. Wherein the response indicates at least a portion of the capabilities that the cooperative terminal 102 may provide to the beneficiary terminal 101. At least a portion of the capabilities of the collaboration terminal 102 include at least one of: at least a part of the multiple input multiple output (MIMO-LayersUL) layers of the cooperative terminal 102 and/or the number of at least a part of antenna Ports (maxnumberber SRS-Ports-per resource) transmitting Sounding Reference Signals (SRS) in a unit resource.
As shown in block 805 of fig. 8, the capabilities of the beneficiary terminal 101 are accumulated with at least a portion of the capabilities from the cooperating terminals to obtain an added result. For example, the controller 211 of the beneficiary terminal 101 accumulates the capabilities of the beneficiary terminal 101 with at least a portion of the capabilities from the cooperating terminals to obtain an added result. Wherein the capabilities of the benefitting terminal include at least one of the following capabilities: benefit from the number of MIMO-LayersUL layers of terminal 101 and the number of maximum antenna Ports (maxnumberberrss-Ports-resource) for transmitting Sounding Reference Signal (SRS) in a unit resource.
As shown in block 806 of fig. 8, a determination is made as to whether the result of the addition is less than the upper capability limit. For example, the controller 211 of the beneficiary terminal 101 determines whether the result of the addition is less than the capability upper limit. The upper capability limit may be understood as the maximum limit of signal transmission between the user equipment (e.g. the benefit terminal 101) and the base station 103. Wherein the maximum limit of signal transmission may include a maximum limit of the number of layers of mimo (e.g. 4 layers).
As shown in block 807 in fig. 8, if the controller 211 of the beneficial terminal 101 determines that the result of the addition is less than the capability upper limit, the result of the addition is taken as the integrated capability of the beneficial terminal 101. For example, the controller 211 of the beneficial terminal 101 determines that the result of the addition is less than the capability upper limit, then the controller 211 of the beneficial terminal 101 takes the result of the addition as the integrated capability of the beneficial terminal 101.
As indicated by block 809 in fig. 8, if the controller 211 of the beneficiary terminal 101 determines that the result of the adding is greater than or equal to the capability cap, then the capability cap is taken as the integrated capability of the beneficiary terminal 101. For example, the controller 211 of the beneficial terminal 101 determines that the added result is greater than or equal to the capability cap, then the controller 211 of the beneficial terminal 101 takes the capability cap as the integrated capability of the beneficial terminal 101.
The result of the addition is subtracted from the upper limit of the capability to obtain the excess capability, as shown in block 810 of fig. 8. For example, the controller 211 of the beneficiary terminal 101 subtracts the added result from the capability upper limit to obtain the excess capability.
As shown in block 811 in fig. 8, the excess capacity is sent to the cooperative terminal 102. For example, the transceiver 221 of the beneficiary terminal 101 transmits the excess capacity to the transceiver 222 of the cooperative terminal 102.
The integrated capabilities are sent to the base station 103, as shown at block 812 in fig. 8. For example, the transceiver 221 of the benefit terminal 101 transmits the integrated capabilities of the benefit terminal 101 to the transceiver 223 of the base station 103.
As shown in block 813 of fig. 8, parameter configuration information is received from the base station 103, and transmission and/or measurement of information is performed with the base station 103 using communication resources (number of antenna ports, number of streams of signal stream) corresponding to the parameter configuration. For example, the transceiver 221 of the beneficiary terminal 101 receives the parameter configuration information from the base station 103, and performs transmission and/or measurement of information with the base station 103 using the communication resources (number of antenna ports, number of streams of signal stream) corresponding to the parameter configuration.
As shown in block 808 in fig. 8, if the quality of the transmission information between the beneficiary terminal 101 and the base station 103 is higher than or equal to the quality threshold, then no cooperation request is sent to the cooperative terminal 102. For example, the controller 211 of the beneficiary terminal 101 determines that the quality of the information transmitted between the beneficiary terminal 101 and the base station 103 is greater than or equal to the quality threshold, then the transceiver 221 of the beneficiary terminal 101 does not transmit a cooperation request to the transceiver 222 of the cooperative terminal 102.
In the case that the beneficiary terminal 101 is limited by the capability, resulting in poor quality of transmission with the base station 103 (e.g. high retransmission rate, high error rate, and long delay), the beneficiary terminal 101 improves the capability of communication between the beneficiary terminal 101 and the base station 103 by using at least a part of the capability (full capability or partial capability) of the cooperative terminal 102 having short-range communication with the beneficiary terminal 101, thereby improving the transmission quality.
Fig. 9 illustrates a method for providing capability of transmitting information to benefit terminals by a cooperative terminal according to some embodiments of the present application.
As shown in block 901 of fig. 9, a cooperation request from a beneficiary terminal 101 is received. For example, the transceiver 222 of the cooperative terminal 102 receives the cooperation request transmitted from the transceiver 221 of the beneficiary terminal 101.
As shown at block 902 in fig. 9, at least a portion of capabilities that may be provided to the beneficiary terminal 101 by the coordinating terminal 102 are determined in response to a cooperation request by the beneficiary terminal 101. For example, the controller 212 of the cooperative terminal 102 determines at least a portion of the capabilities that the cooperative terminal 102 may provide to the beneficiary terminal 101 in response to the cooperation request of the beneficiary terminal 101. If the cooperative terminal 102 does not need to communicate with the base station 103, the cooperative terminal 102 may provide full capabilities to the beneficiary terminal 101; if the cooperative terminal 102 needs to communicate with the base station 103, the cooperative terminal 102 may provide the benefit terminal 101 with capabilities other than those required for its own communication. After the beneficiary terminal 101 establishes a cooperative relationship with the cooperative terminal 102 (e.g., in fig. 5, the user clicks the consent 501 button on the user interface of the cooperative terminal 102), the controller 212 of the cooperative terminal 102 may determine to provide all or part of the capabilities to the beneficiary terminal 101. The cooperative terminal 102 may determine the capabilities that the cooperative terminal 102 provides to the beneficiary terminal 101 in a manual or automatic manner. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in a manual manner, please refer to fig. 6 and the related description thereof, which are not repeated herein. For how the cooperative terminal 102 specifically determines the capability provided by the cooperative terminal 102 to the beneficiary terminal 101 in an automatic manner, please refer to fig. 2 and the related description thereof, which are not repeated herein.
As shown in block 903 of fig. 9, it is determined whether at least a portion of the capabilities provided by the collaboration terminal 102 are full capabilities. Whether at least a portion of the transmission capabilities are full (100% of the capabilities) may be determined by the controller 212 of the cooperative terminal 102.
As shown in block 904 of fig. 9, if at least a portion of the capabilities provided by the cooperative terminal 102 are full capabilities, then a determination is made as to whether an excess capability returned to the cooperative terminal 102 by the beneficiary terminal 101 has been received. For example, the controller 212 of the cooperative terminal 102 determines whether an excess capacity returned by the beneficiary terminal 101 to the cooperative terminal 102 is received. Where out-of-capability is understood to mean that no capability is needed to benefit the transmission of information between terminal 101 and base station 103.
As shown in block 905 of fig. 9, if the cooperative terminal 102 receives the excess capacity returned by the benefit terminal 101, the cooperative terminal 102 will exceed the capacity as the integrated capacity. For example, if the transceiver 222 of the cooperative terminal 102 receives excess capacity returned by the beneficiary terminal 101, the controller 222 of the cooperative terminal 102 will exceed the capacity as an integrated capacity. The process of the collaboration terminal 102 integration is as follows: the full capability of the cooperative terminal 102 minus the capability (i.e., full capability) provided by the cooperative terminal 102 to the beneficiary terminal 101 plus the excess capability returned by the beneficiary terminal 101.
As shown in block 908 in fig. 9, if the cooperative terminal 102 does not receive the excess capability returned by the beneficial terminal 101, the cooperative terminal 102 does not transmit the capability to the base station 103. For example, if the transceiver 222 of the cooperative terminal 102 does not receive the excess capacity returned by the beneficiary terminal 101, then the transceiver 222 of the cooperative terminal 102 does not transmit the capacity to the transceiver 223 of the base station 103.
As shown in block 909 of fig. 9, if at least a portion of the capabilities provided by the cooperative terminal 102 are not all capabilities (e.g., provide a portion of the capabilities), then a determination is made as to whether an excess capability of the benefit terminal 101 to return to the cooperative terminal 102 is received, e.g., the controller 212 of the cooperative terminal 102 determines whether an excess capability of the benefit terminal 101 to return to the cooperative terminal 102 is received.
As shown in block 910 of fig. 9, if the cooperative terminal 102 receives the excess capacity returned by the beneficial terminal 101, the remaining capacity of the cooperative terminal 102 and the excess capacity returned by the beneficial terminal 101 are accumulated, and the added result is used as the integrated capacity. For example, if the transceiver 222 of the cooperative terminal 102 receives the excess capacity returned by the transceiver 221 of the beneficial terminal 101, the controller 212 of the cooperative terminal 102 accumulates the remaining capacity of the cooperative terminal 102 with the excess capacity returned from the beneficial terminal 101 and takes the added result as the integrated capacity. The remaining capability may be understood as a capability other than a part of the capability for transmitting information between the cooperative terminal 102 and the base station 103.
If the cooperative terminal 102 does not receive the excess capacity returned by the beneficiary terminal 101, the remaining capacity is taken as the integrated capacity, as shown in block 911 in fig. 9. For example, if the transceiver 222 of the cooperative terminal 102 does not receive the excess capacity returned by the transceiver 221 of the beneficiary terminal 101, the controller 212 of the cooperative terminal 102 takes the remaining capacity as the integrated capacity. The process of the collaboration terminal 102 integration is as follows: the total capability of the cooperative terminal 102 minus the capability (i.e., partial capability) provided by the cooperative terminal 102 to the beneficiary terminal 101
The integrated capabilities are transmitted to the base station 103 as shown at 906 in fig. 9. For example, the transceiver 222 of the cooperative terminal 102 transmits the integrated capabilities of the cooperative terminal 102 to the transceiver 223 of the base station 103.
As indicated at 907 in fig. 9, parameter configuration information is received from the base station and transmission and/or measurement of information is performed with the base station using communication resources corresponding to the parameter configuration. For example, the transceiver 222 of the cooperative terminal 102 receives the parameter configuration information from the base station 103, and the controller 212 of the cooperative terminal performs information transmission and/or measurement with the base station using the communication resource corresponding to the parameter configuration. In an embodiment, the base station 103 sends an RRC Connection Reconfiguration message to the cooperative terminal 101 to perform parameter Reconfiguration of the cooperative terminal 101, where the parameters include SRB1 (SRB: Signaling radio bearers), radio resources, SRB2 and DRB (DRB: radio bearers, Data radio bearers), and so on. For example, the radio resource in the above parameters includes an SRS, and the base station 103 may obtain the link condition of the cooperative terminal 102 and the base station 103 by measuring the SRS.
For the cooperative terminal 102, since all or part of the capabilities can be provided to the beneficial terminal 101 according to its own communication requirement, the cooperative terminal 102 may ensure the communication between itself and the base station 103 without affecting the cooperative relationship with the beneficial terminal 101.
