Description

Indication method of antenna configuration, base station, terminal and computer storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an indication method for antenna configuration, a base station, a terminal, and a computer storage medium.

background

With the evolution of technology and the increase of data services, a 5G New Radio (5G NR) system supports a larger bandwidth and a more complex service, which may cause a terminal to consume more power when performing the service.

When a terminal is in a Radio Resource Control (RRC) connected state, the terminal needs to continuously monitor a Physical Downlink Control Channel (PDCCH) to obtain transmission information of a Physical Downlink Shared Channel (PDSCH). The terminal continuously monitors the PDCCH, which inevitably causes fast power consumption of the UE, so that at present, the network side can configure the terminal to periodically monitor whether data arrives, and in a Discontinuous Reception (DRX) mode, the terminal periodically monitors a data channel, and if no data exists, the terminal enters a sleep state, so as to achieve the purpose of saving power.

However, for the 5G NR system, the terminal consumes more power because it supports a larger bandwidth and more complicated services.

The embodiment of the invention provides an indicating method of antenna configuration, a base station, a terminal and a computer storage medium, which are used for indicating the terminal to select the number of transmitting and receiving antennas so as to achieve the effect of saving electricity.

In a first aspect, a method for indicating an antenna configuration is provided, where the method includes:

the base station generates antenna configuration information according to the service state information and/or the channel quality information or according to the indication fed back by the terminal; the antenna configuration information is used for indicating the number of the transmitting antennas and/or the receiving antennas selected by the terminal; the service state information is used for indicating the size of data volume to be transmitted by a terminal, the channel quality information comprises Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ) fed back by the terminal, and the indication fed back by the terminal is used for indicating the requirement of the terminal on power consumption saving;

and the base station indicates the antenna configuration information to the terminal.

in the embodiment of the invention, the number of the receiving and transmitting antennas selected by the terminal is considered to be related to power consumption, and more receiving and transmitting antennas mean that the power consumption is larger, so that the base station in the embodiment of the invention generates the antenna configuration information according to the service state information and/or the channel quality information or the indication fed back by the terminal. That is, the base station generates the antenna configuration information according to the size of the data volume to be transmitted by the terminal, and if the data volume is smaller, the number of the transmitting antennas and/or the receiving antennas indicated by the configured antenna configuration information is smaller, so that the effect of saving electricity is achieved. Or the base station generates the antenna configuration information according to the quality degree of the channel quality, and if the channel quality is better, the number of the transmitting antennas and/or the receiving antennas indicated by the configured antenna configuration information is less, so that the effect of saving electricity is achieved. Or the base station generates the antenna configuration information according to the power consumption saving requirement fed back by the terminal, namely the base station generates the antenna configuration information according to the actual power consumption saving requirement of the terminal so as to enable the terminal to save power. Compared with the current terminal which only realizes the purpose of saving electricity through a periodic monitoring data channel, the base station in the embodiment of the invention instructs the terminal to select the number of the receiving and transmitting antennas according to the actual transmission data volume or the channel quality of the terminal or the requirement of the terminal on saving the power consumption, so that the terminal can save electricity.

The above two alternative ways describe how the base station generates the antenna configuration information, i.e. how to determine the number of transceiving antennas of the terminal. One way is that the base station may generate the antenna configuration information according to the traffic status information sent by the terminal when RSRP or RSRQ sent by the terminal exceeds a preset threshold, that is, the base station generates the antenna configuration information by comprehensively considering the channel quality and the size of the data volume transmitted by the terminal. The other way is that the base station informs the base station of the requirement for power consumption according to an indication fed back by the terminal, for example, a low power consumption indication, that is, a terminal, and at this time, the base station may generate a configuration of less than 2 receiving antennas or 2 transmitting antennas, that is, antenna configuration information with less data of the receiving and transmitting antennas, so as to meet the requirement for low power consumption by the terminal.

Or the base station generates the antenna configuration information according to the power consumption saving requirement fed back by the terminal, namely the base station generates the antenna configuration information according to the actual power consumption saving requirement of the terminal so as to enable the terminal to save power.

Detailed Description

in order to make the objects, technical solutions and advantages of the present invention more clearly and completely apparent, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

in view of this, the embodiments of the present invention consider that the number of the transceiver antennas selected by the terminal is related to power consumption, and more transceiver antennas means more transceiver channels, so that power consumption is larger. That is, the larger the number of antennas of the terminal, the more the transmission/reception channels, the more power consumption. How to effectively adjust the number of the receiving and transmitting antennas of the indication terminal and further adjust the number of the receiving and transmitting radio frequency/baseband channels of the terminal is an effective technical direction for saving the power consumption of the terminal.

in order to reduce power consumption of the terminal, the base station in the embodiment of the present invention generates the antenna configuration information according to the traffic status information and/or the channel quality information or the indication fed back by the terminal. That is, the base station generates the antenna configuration information according to the size of the data volume to be transmitted by the terminal, and if the data volume is smaller, the number of the transmitting antennas and/or the receiving antennas indicated by the configured antenna configuration information is smaller, so that the effect of saving electricity is achieved. Or the base station generates the antenna configuration information according to the quality degree of the channel quality, and if the channel quality is better, the number of the transmitting antennas and/or the receiving antennas indicated by the configured antenna configuration information is less, so that the effect of saving electricity is achieved. Or the base station generates the antenna configuration information according to the power consumption saving requirement fed back by the terminal, namely the base station generates the antenna configuration information according to the actual power consumption saving requirement of the terminal so as to enable the terminal to save power. Compared with the current terminal which only realizes the purpose of saving electricity through a periodic monitoring data channel, the base station in the embodiment of the invention instructs the terminal to select the number of the receiving and transmitting antennas according to the actual transmission data volume or the channel quality of the terminal or the requirement of the terminal on saving the power consumption, so that the terminal can save electricity.

It should be noted that in practical applications, there may be a plurality of physical antennas corresponding to one antenna port, and one antenna port corresponding to one number of rf/baseband channels, but this does not affect the present invention.

It should be noted that the antenna configuration method provided by the present invention is not only used for determining the number of transmit/receive antennas for the terminal to perform data channel transmission, but also used for determining the number of transmit/receive antennas for the terminal to perform data channel transmission.

the technical scheme provided by the embodiment of the invention is described below by combining the accompanying drawings.

Referring to fig. 1, a method for indicating antenna configuration information according to an embodiment of the present invention is described as follows.

S101: and the base station generates antenna configuration information according to the service state information and/or the channel quality information or according to the indication fed back by the terminal.

In the specification of R15, the transmit antennas of a terminal are semi-statically configured and the number of receive antennas depends on the capabilities of the terminal and is therefore not configurable. However, the number of antennas and the number of data transceiving channels are related, and more antennas means more rf and baseband processing channels, which means more power consumption of the terminal. Therefore, in order to enable the terminal to save power consumption, the embodiment of the invention can indicate the number of the transmitting and receiving antennas of the terminal, wherein the transmitting and receiving antennas comprise a transmitting antenna and a receiving antenna.

specifically, the base station may generate antenna configuration information according to an actual requirement of the terminal, where the antenna configuration information may be used to instruct the terminal to select the number of transmit antennas and/or receive antennas, so as to instruct the terminal to select the number of transmit/receive antennas. In the embodiment of the present invention, the base station may determine the number of the transmit/receive antennas of the terminal in the following generation manners, which are described below.

The first generation mode is as follows: and the base station generates antenna configuration information according to the service state information.

The traffic status information may be used to indicate the size of the data amount to be transmitted by the terminal, and the terminal may feed back the traffic status information to the base station. When the service state information indicates that the data volume to be transmitted by the terminal is larger, the number of the receiving and transmitting antennas indicated by the antenna configuration information generated by the base station is also larger, so that the transmission of data streams can be accelerated without affecting the performance of data transmission. And when the service state information indicates that the data volume to be transmitted by the terminal is small, too many antennas and transceiving channels are not needed, and the number of the transceiving antennas indicated by the antenna configuration information generated by the base station is small, so that the purpose of reducing power consumption can be achieved. The embodiment of the invention can not influence the performance of data transmission, and can control the power consumption of the terminal, thereby achieving the purpose of saving power consumption of the terminal.

the second generation mode is as follows: the channel quality information generates antenna configuration information.

The channel quality information may be used to indicate how good the channel quality of the transmission data is, and the terminal may feed back the channel quality information to the base station. In the embodiment of the present invention, the channel quality information may include Reference Signal Received Power (RSRP) and/or Reference Signal Received Quality (RSRQ). When the channel quality information indicates that the quality of the transmission channel is good, the number of the receiving and transmitting channels of the terminal can be reduced, and the number of the receiving and transmitting antennas indicated by the antenna configuration information generated by the base station can be reduced. When the channel quality information indicates that the quality of the transmission channel is poor, in order to ensure the signal coverage performance, the number of the transceiving channels needs to be increased, and at this time, the number of the transceiving antennas indicated by the antenna configuration information generated by the base station may be large. The embodiment of the invention can not influence the performance of data transmission, and can control the power consumption of the terminal, thereby achieving the purpose of saving power consumption of the terminal.

the third generation mode is as follows: the base station in the embodiment of the present invention may combine the first manner and the second manner to generate the antenna configuration information. When the channel quality information is good, the base station can also generate antenna configuration information according to the service state information, so that the performance of the terminal for data transmission is further not influenced, the power consumption of the terminal can be controlled, and the purpose of saving power for the terminal is achieved.

specifically, the base station may generate the antenna configuration information according to the traffic state information sent by the terminal when RSRP or RSRQ sent by the terminal exceeds a preset threshold. If the RSRP or RSRQ sent by the terminal exceeds the preset threshold, it may be considered that the channel transmission quality is better at this time, and then further may generate antenna configuration information according to the traffic state information sent by the terminal, for example, the number of the receiving and sending antennas may be set to be smaller. Conversely, if the RSRP or RSRQ transmitted by the terminal does not exceed the preset threshold, the channel transmission quality may be considered poor at this time, and then the base station may keep the number of transceiving antennas currently selected by the terminal at this time. That is, the base station in the embodiment of the present invention can further determine the size of the data volume to be transmitted by the terminal on the basis of good information transmission quality, and determine the number of the transceiving antennas to be selected by the terminal, thereby achieving the purpose of controlling the power consumption of the terminal and saving power consumption of the terminal without affecting the performance of the terminal in data transmission.

The fourth generation mode: the indication fed back by the terminal generates the power consumption of the antenna configuration information terminal to control, and the purpose of saving power of the terminal is achieved.

the indication fed back by the terminal in the embodiment of the invention can be used for indicating the requirement of the terminal on power consumption saving. For example, the indication fed back by the terminal may be a low power consumption indication, which indicates that the terminal is to meet the requirement of low power consumption at this time. And the base station receives the instruction fed back by the terminal and can generate the antenna configuration information of the low power consumption mode according to the instruction fed back by the terminal. The low power consumption mode antenna configuration information may be used to indicate a configuration including less than 2 receiving antennas or 2 transmitting antennas, that is, the number of receiving antennas or transmitting antennas that may be selected by the terminal is small, so as to meet the requirement of low power consumption of the terminal.

In the above four modes, the terminal needs to correspondingly feed back service state information, channel quality information, or indicate a need for saving power consumption by the terminal, and also needs to monitor antenna configuration information indicated by the base station, so as to adjust the number of transmit/receive antennas selected by the terminal or adjust the number of corresponding transmit/receive radio frequencies or baseband channels according to the antenna configuration information indicated by the base station. Therefore, no matter the terminal sends or receives data in a data channel or a control channel, the number of channels corresponding to the adjusted antenna configuration is used for receiving or sending data, the performance of the terminal for data transmission is not influenced, the power consumption of the terminal can be controlled, and the purpose of saving power of the terminal is achieved.

the antenna configuration information of the base station indication terminal in the embodiment of the present invention may include individual configuration information or joint configuration information. The independent configuration information is information for configuring the receiving antenna and the transmitting antenna by the base station by adopting different signaling or by adopting one signaling at different time. That is, the base station may use different signaling to configure the information of the receiving antenna and the transmitting antenna, respectively, or the base station may also use one signaling to configure the information of the receiving antenna and the transmitting antenna, respectively, at different times. The joint configuration information is information for uniformly configuring the receiving antenna and the sending antenna by the base station by adopting a signaling.

after the base station generates the antenna configuration information, in step S102: the base station indicates the antenna configuration information to the terminal.

The base station in the embodiment of the present invention indicates the antenna configuration information to the terminal differently according to the difference of the antenna configuration information, and how the base station indicates the antenna configuration information to the terminal is described below.

The first indication mode is as follows:

The base station may indicate the antenna configuration information to the terminal through a semi-static indication signaling, where the semi-static indication may include, for example, an RRC signaling, so that the terminal determines the number of the transceiving antennas according to the antenna configuration information after receiving the antenna configuration information.

The base station may also indicate the antenna configuration information to the terminal through a dynamic indication signaling, where the dynamic indication may include, for example, DCI signaling, so that the terminal dynamically receives the antenna configuration information and then adjusts the number of the transceiving antennas according to the antenna configuration information.

The second indication mode is as follows:

The base station may send a transceiving antenna list indicating a number of combinations of the plurality of transmitting antennas and/or receiving antennas to the terminal through RRC signaling, so that the terminal may select one combination from the transceiving antenna list indicating the number of combinations of the plurality of transmitting antennas and/or receiving antennas after receiving the antenna configuration information, and determine the selected combination as the number of transceiving antennas.

Specifically, the base station may provide multiple antenna configuration modes, and different antenna combinations correspond to different configuration modes. The base station may indicate to the terminal a list of transceiving antennas of a plurality of combinations of the numbers of transmitting antennas and/or receiving antennas, which are configured in advance.

The third indication mode is as follows:

The base station may further transmit one of a transceiving antenna list dynamically indicating a number of combinations of a plurality of transmitting antennas and/or receiving antennas to the terminal, where the dynamic indication includes Media Access Control (MAC) signaling or Downlink Control Indication (DCI) signaling.

Specifically, the base station may provide multiple antenna configuration modes, and different antenna combinations correspond to different configuration modes. When the base station determines that the service state information fed back by the terminal indicates that the data volume to be transmitted by the terminal is small, the base station can dynamically indicate one of the plurality of combinations with fewer antenna combinations to achieve the purpose of reducing the power consumption of the terminal. Or, when the base station determines that the quality of the transmission channel indicated by the channel quality information fed back by the terminal is better, the number of the transceiving channels of the terminal can be reduced, and at this time, the base station can dynamically indicate one of a plurality of combinations to the terminal with a relatively small number of antennas. Because the receiving performance of the terminal is better when the signal-to-noise ratio is higher, the number of the receiving and transmitting channels is reduced, the performance of data transmission is not reduced, and the power consumption of the terminal can be reduced.

Specifically, the base station may stipulate various combinations of transmit and receive antennas, for example, the number of transmit antennas: 1, 2, 4, 8; the receive antennas may be 1, 2, 4, 8. There are many combinations of transmit and receive antenna combining indications, see table 1. The base station may indicate a combination of the number of the plurality of transceiving antennas through RRC and then indicate one of the combinations by dynamic MAC signaling or DCI signaling. The terminal can determine how many transceiving antennas are used for data and control channel transmission according to the combination.

TABLE 1

	Number of transmitting antennas	Number of receiving antennas
			Antenna configuration mode 1	Without limitation	without limitation
antenna configuration mode 2	The number of transmitting antennas is 2	The number of receiving antennas is 2
			antenna configuration mode 3	the number of transmitting antennas is 1	the number of receiving antennas is 1

In the embodiment of the present invention, when the base station indicates the antenna configuration information to the terminal, the base station needs to judge the service state information fed back by the terminal in advance, so as to indicate the corresponding antenna combination to the terminal. If the service state information fed back by the terminal indicates that the data volume to be transmitted by the terminal is large, the base station can indicate fewer antenna combinations in various combinations to the terminal. And if the service state information fed back by the terminal indicates that the data volume to be transmitted by the terminal is smaller, the base station can indicate fewer antenna combinations in various combinations to the terminal. For example, the base station may indicate to the terminal the antenna configuration for a single transmission and a single reception.

similarly, when indicating the antenna configuration information to the terminal, the base station needs to determine the channel quality information fed back by the terminal in advance so as to indicate the corresponding antenna combination to the terminal. If the channel quality information fed back by the terminal indicates that the transmission channel quality is better, the base station can indicate more antenna combinations in various combinations to the terminal so as to improve the efficiency of data transmission. And if the channel quality information fed back by the terminal indicates that the transmission channel quality is poor, the base station can indicate fewer antenna combinations in the multiple combinations to the terminal so as to ensure the performance of data transmission.

The base station in the embodiment of the invention considers the size of the data volume to be transmitted by the terminal or the quality degree of the Transmission channel quality, indicates the antenna configuration information through the dynamic signaling, and has less delay and higher efficiency compared with the method for indicating the antenna configuration information by each Transmission Time Interval (TTI).

the fourth indication mode is as follows:

the base station in the embodiment of the present invention may indicate the generated antenna configuration information to the terminal in combination with an indication of a Multiple-Input Multiple-Output (MIMO) system to configure the antenna.

In the configuration of MIMO, if the number of data streams transmitted by the terminal is instructed to be 1, the terminal can operate using a minimum of a single transmission antenna. Also, if the number of data streams received by the terminal is indicated to be 1, the terminal can operate using a minimum of a single receiving antenna.

If the number of ports of the CSI-RS is 1, it means that the terminal only supports a single transmit antenna, and at this time, the communication between the terminal and the base station only has a single data stream transmission, so that 1 transmit antenna of the terminal may be used, and 1 or more receive antennas may be configured as required. If the terminal selects a plurality of receiving antennas, the receiving performance is better, but the power consumption is increased accordingly. Therefore, the base station can instruct the terminal to select one or more receiving antennas according to the service state information or the channel quality information fed back by the terminal.

In the embodiment of the present invention, the sending configuration of the PMI may also affect the number of the transmitting and receiving antennas of the terminal, for example, the base station does not have PMI to send, at this time, the terminal may default to use a single antenna to send, and may implicitly indicate the number of the transmitting and receiving antennas of the terminal for the number of the data streams to be sent and received, for example, the number of the transmitted streams and the number of the received streams are 1, and the terminal may use a single transmitting antenna or a single receiving antenna to complete data transmission.

Specifically, the base station in the embodiment of the present invention may jointly indicate the multi-antenna transmission configuration parameter and the information field of one DCI to the terminal. The multi-antenna transmission configuration parameter is mainly used for indicating the number of transmitting antennas and receiving and transmitting data streams of the terminal, and the information field of the DCI may be used for indicating a low-power-consumption antenna configuration mode or indicating the number of receiving antennas of the terminal. The multi-antenna transmission configuration parameter may include one or more of a number of transmit/receive data streams indicating a terminal, a number of channel state information reference Signal (CSI-RS) ports, a number of demodulation reference Signal (DMRS) ports, and a transmission manner of Precoding Matrix Indication (PMI).

The fifth indication mode is as follows:

the indication mode is that the base station indicates a special combined indication message of the multi-antenna transmission configuration parameters to the terminal. The difference from the fourth approach is that a special combination of multi-antenna configurations is used, which is not used for data transmission indication in conventional MIMO. The combination indication information comprises one or more of the number of data streams to be transmitted and received by the terminal, the number of CSI-RS ports, the number of DMRS ports and the transmission mode of the PMI.

specifically, the information indicating the antenna reception combination of the terminal includes: single stream transmission, single CSI-RS port, PMI indicates a valid precoding codebook, which combination is a special combination because if a single CSI-RS port, the base station is a single transmit antenna, precoding indication is invalid, and using this combination indicates that the terminal needs single antenna reception. Similarly, the DMRS port may be indicated to point to an absent or reserved RS port number, which is also an abnormal combination, and is used as an indication of the low power consumption antenna configuration.

in summary, in the embodiments of the present invention, it is considered that the number of the transceiver antennas selected by the terminal is related to power consumption, and more transceiver antennas mean that the power consumption is larger, so the base station in the embodiments of the present invention generates the antenna configuration information according to the service state information and/or the channel quality information, or according to the indication fed back by the terminal. That is, the base station generates the antenna configuration information according to the size of the data volume to be transmitted by the terminal, and if the data volume is smaller, the number of the transmitting antennas and/or the receiving antennas indicated by the configured antenna configuration information is smaller, so that the effect of saving electricity is achieved. Or the base station generates the antenna configuration information according to the quality degree of the channel quality, and if the channel quality is better, the number of the transmitting antennas and/or the receiving antennas indicated by the configured antenna configuration information is less, so that the effect of saving electricity is achieved. Or the base station generates the antenna configuration information according to the power consumption saving requirement fed back by the terminal, namely the base station generates the antenna configuration information according to the actual power consumption saving requirement of the terminal so as to enable the terminal to save power. Compared with the current terminal which only realizes the purpose of saving electricity through a periodic monitoring data channel, the base station in the embodiment of the invention instructs the terminal to select the number of the receiving and transmitting antennas according to the actual transmission data volume or the channel quality of the terminal or the requirement of the terminal on saving the power consumption, so that the terminal can save electricity.

the embodiment of the invention provides various modes for indicating the antenna configuration information by the base station, and is more flexible. The base station indicates the antenna configuration information through dynamic signaling, and compared with the antenna configuration information indicated by each Transmission Time Interval (TTI), the base station has the advantages of less delay and higher efficiency.
