The Internet of Things is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. For example, the terminal device in the embodiment of the present application may be a wearable device.

[0088] In the Rel-15 protocol standard, network equipment supports a maximum of 8 layers of downlink single-user multiple-input multiple-output (DL) SU-MIMO. However, receiving 8 layers of data has problems with reception complexity and high cost, making it difficult to build terminal devices with multiple antenna receivers. It is necessary to study low-complexity multiple antenna receivers.
[0089] By dividing multiple antenna receivers into two sub-antenna receivers, each sub-antenna receiver can independently receive data sent by a network device, thereby preventing highly complex data from affecting the communication performance of the receiver.
[0090] Figure 2 Schematic diagram of a receiver provided in an embodiment of the present application. Figure 2 As shown, the receiver receives data sent by the network device. The receiver includes 2 sub-receivers, each sub-receiver receives data through 4 antennas, and the receiver as a whole receives data through 8 antennas.
[0091] Combined with the scenario example, refer to Figure 2 For any sub-receiver, receiving data through 4 antennas can significantly reduce the reception complexity compared to a single receiver receiving data through 8 antennas.
[0092] In the Rel-15 protocol standard, for a pair of {channel measurement resources, interference measurement resources}, the terminal device reports 1 RI, 1 wideband PMI, 1 wideband CQI (when the number of layers ≤4) or 2 wideband CQIs (when the number of layers >4). If subband reporting is configured, N subband PMIs, N subband CQIs (when the number of layers ≤4) or 2N subband CQIs (when the number of layers >4) will also be reported, where N is the number of subbands.
[0093] In the process of wireless communication network planning and optimization, the measurement data is obtained through the Channel State Information (CSI) measurement. Engineers can understand the coverage and performance of the network through the measurement data, identify potential problem areas, and formulate targeted optimization measures. In addition, CSI measurement can also be used to support advanced communication technologies such as adaptive modulation and coding and beamforming to improve the overall performance of the system.
[0094] Specifically, CSI measurement includes the following steps: the network device sends specific measurement resources to the terminal device, and the measurement resources are used by the terminal device to perform channel measurement, and report the corresponding measurement results to the network device. After receiving the measurement resources, the terminal will perform a series of measurement operations, including but not limited to the estimation of parameters such as signal strength, phase, and delay. These measurements reflect the current state of the wireless channel, including factors such as scattering, attenuation, and interference. The terminal device feeds back the measured measurement results to the network device through the uplink. These measurement results are usually expressed in a quantized form and may include various channel parameter matrices or statistics. After receiving the measurement results from the terminal device, the network device will perform further processing and analysis. This may include the application of algorithms such as channel estimation, interference suppression, and beamforming to optimize the performance of data transmission and reception. The network device can adjust its transmit power, modulation mode, coding scheme and other parameters to adapt to changes in current channel conditions. These adjustments are intended to maximize data transmission rate, reduce bit error rate and improve communication reliability.
[0095] In the communication protocol, the network equipment supports multi-user multiple-input multiple-output (MU-MIMO) data transmission, that is, the network equipment communicates with multiple terminal devices at the same time to make full use of spatial resources and improve communication throughput. Compared with DL SU-MIMO technology, in which the network equipment sends data streams to a single terminal device at the same time, the network equipment in MU-MIMO technology can send independent data streams to multiple terminal devices at the same time. The data stream of each terminal device is transmitted through different spatial paths (created by multiple antennas between the network device and the terminal device), thereby achieving simultaneous service of multiple terminal devices on the same time and frequency band resources.
[0096] In the MU-MIMO system, the network equipment performs scheduling based on the measurement results sent by the receivers of multiple terminal devices, determines the allocation method of data streams, and sends data streams to the multiple terminal devices according to the allocation method, thereby enabling simultaneous communication of multiple terminal devices.
[0097] In the related art, a terminal device using a dual receiver structure can reduce the reception complexity of receiving measurement resources. When the dual receiver performs measurement and reporting, the two sub-receivers simultaneously measure and obtain measurement results. The measurement results reflect the channel state of the two sub-receivers working simultaneously. The reported measurement results are used by the network device to schedule the data channels corresponding to the two sub-receivers. When the network device schedules one of the sub-receivers of a terminal device with one of the sub-receivers of two terminal devices for MU-MIMO, the measurement results will lead to the problem of low transmission performance of the data channel.
[0098] The technical solutions shown in the present application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist alone or in combination with each other. For the same or similar contents, for example, explanations of terms or nouns, explanations of steps, etc., they can be referenced to each other in different embodiments without repeating the description.

[0100] S301. Receive a first signal through a multiple-input and multiple-output MIMO receiver, where the MIMO receiver includes a first sub-receiver and a second sub-receiver, and the first signal includes measurement resources.
[0101] Optionally, the MIMO receiver includes a functional module, which includes but is not limited to at least one of the following: a radio frequency module, a MIMO equalization module, or a channel decoding module.
[0102] Among them, the RF module is a key component in the wireless communication system, which is used to convert between analog signals and digital signals to realize signal transmission and reception. At the receiving end, the RF module demodulates the received RF signal and restores it to a digital baseband signal, including signal modulation and demodulation, power amplification, filtering, mixing, frequency synthesis and other functions. In the MIMO communication system, the MIMO equalization module is used to correct the signal distortion and multipath effect caused by the wireless channel. By utilizing spatial multiplexing and diversity gain, the transmission rate and reliability of the communication system are improved. The MIMO equalization module can process the multiple antenna signals received by the receiving end, eliminate the interference between the signals, and restore the original data, thereby improving the channel capacity and system performance. The channel decoding module is responsible for decoding the coded signal that is affected by noise, interference and fading after channel transmission, so as to restore the original data as much as possible. In the wireless communication system, in order to combat channel noise and uncertainty, source coding and channel coding are usually performed on the transmitted data. The channel decoding module is the inverse operation of the corresponding encoding process. Its core task is to use the redundant information in the received signal to correct the error bits that occur during the transmission process, thereby ensuring the correct decoding and transmission quality of the data.
[0103] Combined with the scenario example, the terminal device receives and processes the data sent by the network device through the various modules of the receiver, thereby realizing downlink data transmission.
[0104] Next, the functional modules of the sub-antenna receiver are illustrated.
[0105] As an example, the radio frequency module, the MIMO equalization module, and the channel decoding module of the first sub-receiver are respectively independent of the radio frequency module, the MIMO equalization module, and the channel decoding module of the second sub-receiver.
[0106] Next, combine Figure 4 A multiple-input and multiple-output MIMO receiver is described.
[0107] Figure 4 Schematic diagram of a multiple-input and multiple-output MIMO receiver provided in an embodiment of the present application. Figure 4 As shown, the RF module of the first sub-receiver is independent of the RF module of the second sub-receiver, the MIMO equalization module of the first sub-receiver is independent of the MIMO equalization module of the second sub-receiver, and the channel decoding module of the first sub-receiver is independent of the channel decoding module of the second sub-receiver.
[0108] In this example, since the functional modules are independent of each other, a MIMO receiver can be easily constructed by using two sub-receivers, thereby reducing the difficulty of constructing the MIMO receiver.
[0109] S302: Measure the measurement resource to obtain a first measurement result, and send the first measurement result.
[0110] In a feasible implementation manner, sending the first measurement result includes: sending a first sub-measurement result corresponding to the first sub-receiver and a second sub-measurement result corresponding to the second sub-receiver, and the first measurement result includes the first sub-measurement result and the second sub-measurement result.
[0111] Next, combine Figure 5 The sending of the first measurement result is described.
[0112] Figure 5 This is a schematic diagram of sending a first measurement result provided in an embodiment of the present application. Figure 5 As shown, the network device sends a first signal to the terminal device, the terminal device determines a measurement resource based on the first signal, the terminal device performs measurement based on the measurement resource to obtain a first measurement result and a second measurement result, and the terminal device sends a first sub-measurement result and a second sub-measurement result to the network device.
[0113] In conjunction with the scenario example, the first measurement result reflects the channel quality and channel transmission characteristics corresponding to the first sub-receiver, and the second measurement result reflects the channel quality and channel transmission characteristics corresponding to the second receiver.
[0114] In this feasible implementation method, by respectively sending the first measurement result corresponding to the first sub-receiver and the measurement result corresponding to the second sub-receiver, the network device can accurately schedule the data channel corresponding to each sub-receiver according to the first measurement result and the second measurement result, thereby ensuring effective transmission of data.
[0115] In a feasible implementation manner, the first sub-measurement result includes at least one of the following: a rank indication RI corresponding to the first sub-receiver, a first type of precoding matrix indication PMI, a first type of channel quality indication CQI, a second type of PMI, and a second type of CQI; and / or,
[0116] The second sub-measurement result includes at least one of the following: an RI corresponding to the second sub-receiver, a first-type PMI, a first-type CQI, a second-type PMI, and a second-type CQI.
[0117] Optionally, the first type of PMI is a wideband PMI, the first type of CQI is a wideband CQI, the second type of PMI is a subband PMI, and the second type of CQI is a subband CQI.
[0118] Among them, the main difference between wideband PMI and sub-band PMI lies in the measurement range and application scenarios. Wideband PMI provides phase offset information for the entire communication bandwidth, which is suitable for evaluating the overall performance of the link, while sub-band PMI is specifically for the phase offset within a specific frequency band, which is used for fine parameter adjustment and optimization. Wideband CQI's overall assessment of the channel quality of the entire available frequency band reflects the quality profile of signal transmission over the entire bandwidth. Sub-band CQI separately evaluates one or more smaller frequency bands in the system bandwidth, providing more detailed channel quality information, which can reflect the differences in channel conditions on different frequency bands.
[0119] Exemplarily, the first sub-measurement result includes 1 RI, 1 wideband PMI, N subband PMIs, 1 wideband CQI, and N subband CQIs. The second sub-measurement result includes 1 RI, 1 wideband PMI, N subband PMIs, 1 wideband CQI, and N subband CQIs, where N is the number of subbands.
[0120] Optionally, the terminal device sends a second type of PMI or a second type of CQI in response to the measurement indication.
[0121] In conjunction with the scenario example, if the network device configures the terminal device to send the second type of PMI or the second type of CQI, a measurement indication is sent to the terminal device.
[0122] In a feasible implementation manner, the measurement method further includes: measuring a first measurement resource received by the first sub-receiver to obtain the first sub-measurement result, and measuring the first measurement resource received by the second sub-receiver to obtain the second sub-measurement result; or,
[0123] The first measurement resource received by the first sub-receiver is measured to obtain the first sub-measurement result, and the second measurement resource received by the second sub-receiver is measured to obtain the second sub-measurement result.
[0124] In combination with the scenario example, the first measurement resource and the second measurement resource are derived from the measurement resource sent by the network device. If the first sub-receiver receives the first measurement resource and the second sub-receiver receives the first measurement resource, it means that the first sub-receiver and the second sub-receiver receive the same measurement resource. If the first sub-receiver receives the first measurement resource and the second sub-receiver receives the second measurement resource, it means that the first sub-receiver and the second sub-receiver receive different measurement resources.
[0125] In a feasible implementation manner, the first measurement resources include channel measurement resources and / or interference measurement resources; and / or the second measurement resources include channel measurement resources and / or interference measurement resources.
[0126] Among them, the channel measurement resources are used by the terminal equipment to measure the physical signals and time periods of the wireless channel characteristics. The terminal equipment estimates the channel quality, channel state information, channel fading characteristics, channel response or multipath information based on the signals on the channel measurement resources (including but not limited to reference signals or detection signals, etc.). This information is used for resource scheduling, beamforming, precoding selection, modulation and coding scheme selection, etc. to ensure the efficiency and reliability of data transmission on the wireless channel. Interference measurement resources are used to evaluate and analyze the interference level in the system. The terminal equipment determines the interference intensity and characteristics generated by other users, adjacent cells, external signal sources, etc. based on the interference measurement resources. Through interference measurement, the interference conditions inside and outside the network can be better determined and managed, and measures can be taken to reduce the impact of interference on normal communication, such as dynamically adjusting the transmission power, changing the resource allocation strategy, enabling the interference coordination mechanism, etc., thereby improving the overall performance of the system.
[0127] In combination with the scenario example, any sub-receiver can simultaneously receive channel measurement resources and interference measurement resources, or receive one of the channel measurement resources or the interference measurement resources.
[0128] Optionally, the terminal device receives a first indication sent by the network device, and determines the measurement resources corresponding to each sub-receiver according to the first indication.
[0129] A feasible implementation method is that if the RI corresponding to the first sub-receiver is a positive integer, and the RI corresponding to the second sub-receiver is a positive integer; the method also includes: if the RI corresponding to the first sub-receiver is greater than a first threshold and / or the RI corresponding to the second sub-receiver is greater than a second threshold, then measuring the measurement resource, obtaining a second measurement result, and sending the second measurement result.
[0130] Next, combine Figure 6 Transmitting the second measurement result is described.
[0131] Figure 6 Schematic diagram of the second measurement result provided in the embodiment of the present application. Figure 6As shown, the network device sends a first signal to the terminal device, the terminal device determines the measurement resource according to the first signal, the terminal device performs measurement according to the measurement resource to obtain the first measurement result and the second measurement result, and the terminal device sends the first sub-measurement result and the second sub-measurement result to the network device. The terminal device determines whether the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver in the first sub-measurement result and the second sub-measurement result meet the preset conditions. If so, the second measurement result is measured and sent. The preset conditions are that the RI corresponding to the first sub-receiver is a positive integer, the RI corresponding to the second sub-receiver is a positive integer, the RI corresponding to the first sub-receiver is greater than the first threshold and / or the RI corresponding to the second sub-receiver is greater than the second threshold.
[0132] Combined with the scenario example, when the first sub-receiver and the second sub-receiver are measured at the same time, there is interference between the first sub-receiver and the second sub-receiver, and the measurement result obtained at this time is affected by the interference between the first sub-receiver and the second sub-receiver. If the network device schedules the data channel according to the measurement result, it cannot reflect the channel state when each sub-receiver works independently. On this basis, if the network device schedules a sub-receiver of a terminal device to perform MU-MIMO data transmission with a sub-receiver of another terminal device, it will cause the problem of low transmission performance of the data channel. If the RI corresponding to the first sub-receiver is a positive integer and the RI corresponding to the second sub-receiver is a positive integer, it means that the first sub-receiver and the second sub-receiver are measured at the same time, and the measurement result obtained at this time is affected by the interference between the first sub-receiver and the second sub-receiver.
[0133] Furthermore, in combination with a scenario example, in order to avoid the interference between the first sub-receiver and the second sub-receiver affecting the measurement result, the measurement result is obtained under the assumption that only one of the sub-receivers is used to independently receive data. During the measurement process, the sub-receiver performing the measurement does not refer to the interference of the other sub-receiver, and the obtained measurement result can reflect the channel state of a sub-receiver working independently.
[0134] Furthermore, in combination with a scenario example, when the corresponding RI of one of the sub-receivers is less than a certain value, the interference between the sub-receivers does not affect the measurement result. At this time, there is no need to assume that only one of the sub-receivers is used for data reception. The value is represented by the first threshold and / or the second threshold.
[0135] In this feasible implementation, the measurement result obtained by measuring under the assumption that only the first sub-receiver or the second sub-receiver is used for data reception can avoid interference between sub-receivers and reflect the channel state when a sub-receiver works independently. According to the channel quality measurement result under the assumption of single sub-receiver reception, the network device can adopt MU-MIMO transmission mode for the terminal according to the existing MU pairing scheduling strategy when necessary to improve the total throughput of the network.
[0136] In a feasible implementation method, the second measurement result includes a third sub-measurement result and / or a fourth sub-measurement result, wherein the third sub-measurement result is a measurement result under the assumption that only the first sub-receiver is used for data reception; and the fourth sub-measurement result is a measurement result under the assumption that only the second sub-receiver is used for data reception.
[0137] In combination with the scenario example, the terminal device can compare the third sub-measurement result and the fourth sub-measurement result, and select a better sub-measurement result to report to the network device, wherein the better sub-measurement result can be a sub-measurement result with higher throughput or spectrum efficiency. This method can save reporting overhead.
[0138] Combined with the scenario example, the terminal device can report both the third sub-measurement result and the fourth sub-measurement result to the network device, and then the network device selects the appropriate sub-measurement result according to the actual scheduling situation and the possibility of MU pairing to perform DL data scheduling for the terminal device. This method gives the network device greater scheduling flexibility.
[0139] It should be noted that this application does not limit the specific sub-measurement results reported.
[0140] In a feasible implementation manner, the measurement method further includes: sending an X-bit indicator, where the X-bit indicator is used to represent a value combination of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver, where X is determined according to a value range of the value combination, and X is a positive integer.
[0141] In conjunction with the scenario example, X is a positive integer representing the number of bits required for the indicator. The value combination of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver is used to indicate to the network device the maximum number of parallel data supported by the terminal device. In order to use an X-bit indicator to indicate the value combination of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver, it is necessary to determine the value range and the number of combinations of the value combination of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver, and select a suitable X value according to the value range and the number of combinations, so that X bits are sufficient to represent all possible combinations. For example, assuming that the value range of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver are both 0 to 3 (a total of 4 values), then there are 4*4=16 possible combinations of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver. In order to represent these 16 combinations, a sufficiently large X value is required so that 2^X>=16. The smallest such X value is 4, so in this case, a 4-bit indicator is used to represent the value combination of the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver.
[0142] In this feasible implementation, by using a fixed number of bits, the indicator can convey information about the RI corresponding to the first sub-receiver and the RI value corresponding to the second sub-receiver in a compact manner. This compact representation method improves resource utilization and reduces unnecessary bandwidth occupation. The X-bit indicator allows the system to select different combinations of RI values corresponding to the first sub-receiver and the RI value corresponding to the second sub-receiver according to different channel conditions. The terminal device can dynamically adjust the value of the indicator according to its current receiving capability, thereby sending the amount of data to the network device. The use of fixed-size indicators simplifies the hardware and software design of terminal devices and network devices. The terminal device does not need to send complex or variable-length messages to report its capabilities, but can simply set the value of the indicator. Similarly, network devices can easily parse these fixed-size indicators to adjust their transmission strategies. Since the size of the indicator is fixed, no additional signaling is required to determine the length of the indicator, which reduces processing time and transmission delay, allowing the system to respond to channel changes more quickly.
[0143] In a feasible implementation manner, there is at least one positive integer between the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver.
[0144] Combined with the scenario example, if the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver are both 0, it means that the channels corresponding to the first sub-receiver and the second sub-receiver do not have the possibility of spatial diversity or spatial multiplexing gain, that is, all signals received by the two sub-receivers are completely correlated, and independent spatial streams cannot be distinguished. At this time, the terminal device needs to adjust the transmission strategy, including but not limited to: reducing the data transmission rate or changing the beamforming, etc.
[0145] In a feasible implementation manner, the measurement method further includes: receiving a measurement indication, and sending at least a second type of PMI and / or a second type of CQI according to the measurement indication.
[0146] Next, combine Figure 7 The sending of the second type of measurement result is described.
[0147] Figure 7 This is a schematic diagram of sending the second type of measurement results provided in an embodiment of the present application. Figure 7 As shown, the network device sends a first signal to the terminal device, and the network device sends a measurement indication to the terminal device. In response to the measurement indication, the terminal device determines the measurement resource according to the first signal, and the terminal device sends at least the second type of PMI, at least the second type of PMI and the second type of CQI, or at least the second type of CQI.
[0148] In combination with the scenario example, if the network device needs to schedule according to the second type of PMI or the second type of CQI, a measurement indication is sent to the terminal device to instruct the terminal device to measure and send the second type of PMI or the second type of CQI.
[0149] In a feasible implementation manner, the RI corresponding to the first sub-receiver is a positive integer, and the RI corresponding to the second sub-receiver is a positive integer; the measurement method also includes: if the RI corresponding to the first sub-receiver is greater than a first threshold and / or the RI corresponding to the second sub-receiver is greater than a second threshold, then sending the second type of PMI and / or the second type of CQI corresponding to the first sub-receiver, the second type of PMI corresponding to the first sub-receiver is the measurement result under the assumption that only the first sub-receiver is used for data reception, and the second type of CQI is the measurement result under the assumption that only the first sub-receiver is used for data reception; or, if the RI corresponding to the first sub-receiver is greater than the first threshold and / or the RI corresponding to the second sub-receiver is greater than the second threshold, then sending the second type of PMI and / or the second type of CQI corresponding to the second sub-receiver, the second type of PMI corresponding to the second sub-receiver is the measurement result under the assumption that only the second sub-receiver is used for data reception, and the second type of CQI is the measurement result under the assumption that only the second sub-receiver is used for data reception.
[0150] Next, combine Figure 8 The sending of the second type of measurement result is described.
[0151] Figure 8 This is a schematic diagram of sending the second type of measurement results provided in an embodiment of the present application. Figure 8 As shown, the network device sends a first signal to the terminal device, the network device sends a measurement indication to the terminal device, in response to the measurement indication, the terminal device determines the measurement resource according to the first signal, and the terminal device sends RI, the first type of PMI, the second type of PMI, the first type of CQI, and the second type of CQI. The terminal device determines whether the RI corresponding to the first sub-receiver and the RI corresponding to the second sub-receiver meet the preset conditions. If so, the RI, the first type of PMI, the second type of PMI, the first type of CQI, and the second type of CQI are measured and sent under the assumption that only the first sub-receiver or the second sub-receiver is used for data reception. The preset conditions are that the RI corresponding to the first sub-receiver is a positive integer, the RI corresponding to the second sub-receiver is a positive integer, the RI corresponding to the first sub-receiver is greater than the first threshold and / or the RI corresponding to the second sub-receiver is greater than the second threshold.
[0152] Combined with the scenario example, if the RI corresponding to the first sub-receiver is a positive integer and the RI corresponding to the second sub-receiver is a positive integer, it means that the first sub-receiver and the second sub-receiver are measured at the same time, and the measurement result obtained at this time is affected by the interference between the first sub-receiver and the second sub-receiver. At this time, the second type of PMI and / or the second type of CQI are obtained by measuring under the assumption that only one of the sub-receivers is used to independently receive data, which can avoid the interference between the first sub-receiver and the second sub-receiver affecting the second type of PMI and / or the second type of CQI.
[0153] Exemplarily, if the RI corresponding to the first sub-receiver is a positive integer, the RI corresponding to the second sub-receiver is a positive integer, the RI corresponding to the first sub-receiver is greater than the first threshold and / or the RI corresponding to the second sub-receiver is greater than the second threshold, then under the assumption that only the first sub-receiver is used for data reception, 1 wideband PMI, N sub-band PMIs, 1 wideband CQI, and N sub-band CQIs corresponding to the first sub-receiver are measured. Or under the assumption that only the second sub-receiver is used for data reception, 1 wideband PMI, N sub-band PMIs, 1 wideband CQI, and N sub-band CQIs corresponding to the second sub-receiver are measured.
[0154] In combination with the scenario example, the terminal device can compare the measurement result corresponding to the first sub-receiver with the measurement result corresponding to the second sub-receiver, and select a better sub-measurement result to report to the network device, wherein the better sub-measurement result can be a sub-measurement result with higher throughput or spectrum efficiency. This method can save reporting overhead.
[0155] Combined with the scenario example, the terminal device can report both the measurement results corresponding to the first sub-receiver and the measurement results corresponding to the second sub-receiver to the network device, and then the network device selects the appropriate sub-measurement results according to the actual scheduling situation and the possibility of MU pairing to perform DL data scheduling for the terminal device. This method gives the network device greater scheduling flexibility.
[0156] In this feasible implementation, by measuring the second type of PMI and / or the second type of CQI obtained under the assumption that only the first sub-receiver or the second sub-receiver is used for data reception, interference between sub-receivers can be avoided, reflecting the channel state when a sub-receiver works independently. According to the channel quality measurement result under the assumption of a single sub-receiver receiving, the network device can adopt the MU-MIMO transmission mode for the terminal according to the existing MU pairing scheduling strategy when necessary to improve the total throughput of the network.

[0159] A first receiving module 91 is configured to receive a first signal through a multiple-input and multiple-output MIMO receiver, wherein the MIMO receiver includes a first sub-receiver and a second sub-receiver, and the first signal includes a measurement resource;
