Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to MIMO transmission methods, apparatus, electronic devices and storage media. Background Technology

[0002] Multiple-input multiple-output (MIMO) systems use multiple transmit antennas and receive antennas at the transmitting and receiving ends, respectively, so that signals can be transmitted through multiple antennas at the transmitting and receiving ends.

[0003] Both fourth-generation (4G) and fifth-generation (5G) mobile communication networks are deployed in higher frequency bands, and base station planning largely utilizes existing site resources. This results in numerous areas of weak coverage within the current network.

In related technologies, MIMO transmission results in poor uplink coverage, poor battery life for mobile terminals, and poor communication quality, negatively impacting user experience.

[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0061] To facilitate understanding by those skilled in the art, this disclosure provides multiple implementation methods to clearly illustrate the technical solutions of the embodiments of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0062] To facilitate understanding of any embodiment of this disclosure, the application scenarios of MIMO transmission will first be described:

[0063] In one embodiment, all transmit antennas of the MIMO transmit data regardless of whether data is transmitted using diversity or multiplexing. In diversity transmission, multiple antennas transmit repetitive data; in multiplexing transmission, multiple antennas transmit different data.

[0064] In one embodiment, the uplink transmit power of the terminal is limited in areas with weak coverage. The current maximum transmit power is 23dBm or 26dBm, but according to the link budget, in areas with weak coverage, the terminal should transmit power much greater than the terminal's maximum transmit power, which leads to poor uplink coverage.

[0065] In one embodiment, when the terminal uses multiple antennas to continuously transmit at high power, the terminal power consumption is very high, and the terminal's power is consumed very quickly, which seriously affects the user experience.

[0066] In one embodiment, when performing uplink diversity transmission in a weak coverage area, the maximum power of each antenna can be the ratio of the maximum transmit power specified in the protocol to the number of antennas. The more antennas there are, the lower the maximum power of each antenna will be, which will further shorten the distance of the terminal signal radiation. Moreover, MIMO has higher requirements for channel quality, which will result in many bit errors.

[0067] Figure 1a Figure 1 is a flowchart illustrating a MIMO transmission method according to an exemplary embodiment. The method is applied to a terminal and includes:

[0068] Step 11: Obtain the terminal's remaining transmit power and uplink transmission quality;

[0069] Step 12: Based on the remaining transmission power and the uplink transmission quality, perform MIMO transmission in the transmission state determined from the alternative transmission states of the terminal, wherein the alternative transmission states include multiple transmission states with different uplink coverage capabilities.

[0070] Here, the terminal can be a mobile terminal, a desktop computer, or a smart home device, etc.; wherein, the mobile terminal can be a mobile phone, wearable device, tablet computer, or laptop computer; and the smart home device can be a television set, etc.

[0071] It should be noted that the network-side equipment involved in this disclosure can be a base station. Here, the base station can be of various types, such as a base station for a third-generation mobile communication (3G) network, a base station for a fourth-generation mobile communication (4G) network, a base station for a fifth-generation mobile communication (5G) network, or other evolved base stations.

[0072] In one embodiment, in response to the network coverage capability of the base station being less than or equal to a capability threshold, the transmission power of the terminal is greater than a power threshold. Alternatively, in response to the network coverage capability of the base station being greater than or equal to the capability threshold, the transmission power of the terminal is less than the power threshold. This allows the transmission power of the terminal to be adapted to the network coverage capability of the base station.

[0073] In one embodiment, in a first area covered by the network, the terminal's transmission power is a first transmission power; in a second area covered by the network, the terminal's transmission power is a second transmission power. The first transmission power is less than the second transmission power in response to a network coverage capability greater in the first area than in the second area. Alternatively, the first transmission power is greater than the second transmission power in response to a network coverage capability less in the first area than in the second area.

[0074] In one embodiment, the network coverage capability in a first network coverage area is a first network coverage capability; the network coverage capability in a second network coverage area is a second network coverage capability. The first network coverage capability is greater than the second network coverage capability. In response to a terminal moving from the first area to the second area, the terminal's transmission power is adjusted from a first transmission power to a second transmission power. The first transmission power is less than the second transmission power.

[0075] In one embodiment, in response to the terminal's transmit power being greater than a power threshold, the terminal's remaining transmit power and uplink transmission quality are obtained.

[0076] In one embodiment, in response to the terminal's transmit power being greater than or equal to its maximum transmit power, the terminal's remaining transmit power and uplink transmission quality are obtained.

[0077] In one embodiment, the remaining transmit power and uplink transmission quality of the terminal are acquired at predetermined intervals. Here, the predetermined interval can be determined based on the network coverage capability of the base station. In one embodiment, the predetermined interval is determined to be less than a interval threshold in response to the base station's network coverage capability being less than or equal to a capability threshold. Alternatively, the predetermined interval is determined to be greater than a interval threshold in response to the base station's network coverage capability being greater than or equal to a capability threshold. This allows the predetermined interval to be adapted to the network coverage capability of the base station.

[0078] Here, the remaining transmission power refers to the transmission power that the terminal can currently still use for data transmission. For example, if the terminal's maximum transmission power is 30W, and 25W has already been used for data transmission, then the terminal's remaining transmission power is 5W.

[0079] In one embodiment, in response to the number of antennas used for data transmission being greater than or equal to a number threshold, the transmit power is greater than a power threshold and the remaining transmit power is less than a remaining transmit power threshold. Alternatively, in response to the number of antennas used for data transmission being less than or equal to a number threshold, the transmit power is less than a power threshold and the remaining transmit power is greater than a remaining transmit power threshold.

[0080] For example, if the terminal's maximum transmit power is 30W, and the terminal has four transmit antennas, all of which are used to transmit data, with each antenna having a transmit power of 5W, the terminal's total transmit power is 20W, and the terminal's remaining transmit power is 10W. Alternatively, if the terminal has four transmit antennas, with two antennas used to transmit data, and each antenna having a transmit power of 5W, the terminal's total transmit power is 10W, and the terminal's remaining transmit power is also 20W.

[0081] Here, the uplink transmission quality can correspond to the cyclic redundancy check (CRC) result. In one embodiment, the uplink transmission quality may include the bit error rate (BLER). Here, the bit error rate is greater than or equal to a bit error rate threshold, and the uplink transmission quality is less than a quality threshold. Alternatively, the bit error rate is less than or equal to a bit error rate threshold, and the uplink transmission quality is greater than a quality threshold.

[0082] In one embodiment, the maximum power of each antenna of the terminal can be the ratio of the maximum transmit power specified in the protocol to the number of antennas.

[0083] In one embodiment, the MIMO transmission can utilize diversity transmission to transmit data. Here, diversity transmission involves transmitting different data on different antennas. This increases the data transmission rate.

[0084] In one embodiment, the MIMO transmission may utilize multiplexing to transmit data. Here, multiplexing can be used to transmit the same data on different antennas. This improves the reliability of the transmitted data.

[0085] In one embodiment, the terminal performs MIMO transmission in a first transmission state; in response to the terminal's remaining transmit power being less than a power threshold and the uplink transmission quality being less than a first quality threshold, the terminal switches to a second transmission state for MIMO transmission. In the first transmission state, the transmit power of each transmit antenna of the terminal is the average of the maximum transmit power relative to the number of transmit antennas. Here, in the first transmission state, the number of transmit antennas can be two. In the second transmission state, the transmit power of the terminal's transmit antenna is the maximum transmit power. Here, in the second transmission state, the number of transmit antennas is one.

[0086] In one embodiment, the terminal performs MIMO transmission in a second transmission state; in response to the terminal's remaining transmit power being less than a power threshold and the uplink transmission quality being less than a second quality threshold, the terminal selects to switch to performing MIMO transmission in a third transmission state. In the third transmission state, the transmit power of the terminal's transmit antenna is the maximum transmit power. Here, in the third transmission state, the number of transmit antennas is one. The uplink coverage capability of the first transmission state is less than the uplink coverage capability of the second transmission state; the uplink coverage capability of the second transmission state is less than the uplink coverage capability of the third transmission state. Here, the first quality threshold is greater than the second quality threshold.

[0087] In one embodiment, the terminal performs MIMO transmission in a third transmission state; in response to the terminal's remaining transmission power being greater than a power threshold or its uplink transmission quality being greater than a third quality threshold, the terminal selects to switch to a first transmission state for MIMO transmission. Here, the third quality threshold is greater than the first quality threshold.

[0088] In one embodiment, the terminal performs MIMO transmission in a second transmission state; in response to the terminal's remaining transmission power being greater than a power threshold or its uplink transmission quality being greater than a third quality threshold, the terminal selects to switch to a first transmission state for MIMO transmission. Here, the third quality threshold is greater than the first quality threshold.

[0089] In the embodiments of this disclosure, MIMO transmission is performed under a transmission state determined from the terminal's candidate transmission states, based on the remaining transmission power and the uplink transmission quality. The candidate transmission states include multiple transmission states with different uplink coverage capabilities. Since the candidate states include multiple transmission states with different uplink coverage capabilities, the terminal can select a transmission state with different uplink coverage capabilities from the candidate states for MIMO transmission based on the remaining transmission power and the uplink transmission quality. Compared to a method where the terminal can only perform MIMO transmission under fixed transmission states, this method allows for timely adjustment of the terminal's uplink coverage capability, reducing the bit error rate and improving the transmission quality of MIMO transmission.

[0091] In one embodiment, the alternative transmission state includes:

For example, if the maximum transmission power is 20W, then the transmission power of each transmission antenna is 5W.

[0093] In the second transmission state, the transmission power of the terminal's transmission antenna is at its maximum transmission power; here, the number of transmission antennas used for MIMO transmission can be one.

[0094] In the third transmission state, the transmission power of the terminal's transmission antenna is at its maximum transmission power; here, the number of transmission antennas used for MIMO transmission can be one.

[0095] Wherein, the uplink coverage capability of the first transmission state is less than that of the second transmission state; the uplink coverage capability of the second transmission state is less than that of the third transmission state.
