The MME belongs to a control plane part and is responsible for mobility management of the control plane, including user context and mobile state management, user temporary identity allocation and the like; the SGW belongs to a user plane part and is responsible for initiating paging for downlink data in an idle state, managing and storing Internet Protocol (IP) bearer parameters and routing information in a network and the like between networks; the MME and the SGWs are connected in a mesh mode, and one MME can control a plurality of SGWs.
It should be understood that the base station 102 shown in this embodiment may also be an access point, which is used to provide service for the terminal 103, and one or more transmitting antennas and one or more receiving antennas are used between the base station 102 and the terminal 103 for signal transmission.
The terminal 103 shown in this embodiment may also be referred to as a Mobile Station (MS) or a mobile terminal (mobile). Which may communicate with the core network device 101 via a Radio Access Network (RAN). And the terminal 103 may be a mobile phone (or referred to as a "cellular" phone), a tablet computer, a personal digital assistant, and a computer having a mobile terminal, and may also be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device.
Specifically, the base station 102 shown in this embodiment may serve a cell in a geographic area, and the terminal 103 may reside in the cell, so that the terminal 103 residing in the cell and the base station 102 perform communication.
In order to satisfy the dependence and requirements of modern society on communication, the efficiency of the wireless communication system shown in fig. 1 needs to be continuously improved. The efficiency of a wireless communication system, to speak of, the spectrum utilization and power utilization. Especially in the case of wireless communication, the utilization of these two metrics is higher, especially the spectrum utilization. Accordingly, various communication technologies with higher spectral efficiency are continuously being developed. Among them, Orthogonal Frequency Division Multiplexing (OFDM) is a special multi-carrier modulation technique, which utilizes the orthogonality between carriers to further improve the spectrum utilization rate, and can resist narrowband interference and multipath fading. The OFDM transmits serial data in parallel through a plurality of orthogonal subcarriers, can increase the width of code elements, reduce frequency bands occupied by single code elements, resist frequency selective fading caused by multipath, effectively overcome intersymbol interference, reduce the requirements of a system on an equalization technology, and is one of main technologies for improving the efficiency of a communication system.
Currently, the fourth Generation mobile communication technology (4G) and the fifth Generation mobile communication technology (5G) are designed based on OFDM. The basic idea of OFDM is to modulate serial data in parallel onto multiple orthogonal subcarriers, which can reduce the symbol rate of each subcarrier, increase the symbol period of the symbol, and improve the anti-fading and interference capabilities of the system, and at the same time, because of the orthogonality of each subcarrier, the utilization rate of the spectrum is greatly improved, so it is very suitable for high-speed transmission in mobile occasions.
4G and 5G technologies adopt OFDM-based orthogonal frequency division multiplexing technology. In the frequency band, 5G supports communication in the millimeter wave band. Although the millimeter wave band brings a large channel bandwidth, the problem that the path loss is too large and the penetration force is weakened due to too high frequency is caused. To solve the problem of fast signal attenuation of millimeter waves arriving at the terminal, beamforming techniques may be used to increase the signal reception capability of the terminal 103. The beamforming is present both on the base station 102 side and on the terminal 103 side, as shown in particular in fig. 2.
In the millimeter wave antenna, in order to adapt to the problem of signal reception attenuation caused by environmental change and rotation factors of the terminal 103, taking fig. 3 as an example, antenna channels of the terminal 103 are distributed around the terminal 103, each antenna channel covers a specific direction, as shown in fig. 3, the terminal 103 may be configured with four antenna channels, such as an antenna channel 301, an antenna channel 302, an antenna channel 303, and an antenna channel 304, and the antenna channel 301, the antenna channel 302, the antenna channel 303, and the antenna channel 304 are respectively disposed at four sides of the terminal 103, so that the four antenna channels have different receiving directions.

In a seventh alternative example of the antenna channel, when the rf channel is integrated with an antenna, an rf front-end device 403 and an rf transceiver 402, the antenna channel includes an rf channel.
A fourth alternative example of the antenna channel shown above is described in detail below with reference to fig. 6:
in this embodiment, specific number of antenna channels included in the terminal is not limited, and optionally, the terminal has four antenna channels, that is, a first antenna channel, a second antenna channel, a third antenna, and a fourth antenna channel are taken as an example for exemplary explanation:
a specific structure of the first antenna channel is exemplarily described below, the first antenna channel includes a radio frequency channel 601 for receiving a signal and an antenna 404, one end of the radio frequency channel 601 is connected to the antenna 404, and the other end of the radio frequency channel 601 is connected to a baseband chip 401 inside a terminal.
Specifically, from a physical structure, the radio frequency channel 601 may include a band pass filter, a low noise amplifier, and a down converter included in the radio frequency front end device 403, and the radio frequency channel 601 further includes a demodulator included in the radio frequency transceiver 402;
more specifically, the antenna 404 transmits the received wireless signal to a band-pass filter, the band-pass filter filters an outgoing radio frequency signal, the low-noise amplifier amplifies the selected radio frequency signal, the down-converter converts the radio frequency signal into an intermediate frequency signal, and the down-converter demodulates the intermediate frequency signal to convert a frequency band signal into a baseband signal, so as to transmit the baseband signal to the baseband chip 401.
The second antenna channel includes an antenna 405 and a radio frequency channel 604 for receiving signals, the third antenna channel includes an antenna 406 and a radio frequency channel 607 for receiving signals, the fourth antenna channel includes an antenna 407 and a radio frequency channel 610 for receiving signals, and detailed descriptions of specific structures and connection manners are given in detail in the above description of the first antenna channel and are not repeated.
It should be understood that the radio frequency channel shown in fig. 6 is only a specific example, and the physical structure of the radio frequency channel is not strictly limited in the embodiments of the present application. In addition, in a specific implementation, there may be a case where a plurality of rf channels share some devices, for example, two rf channels may share one filter, which is not specifically limited in this embodiment of the present application.
Any antenna included in the antenna channel of the terminal 103 shown in this embodiment may have 8 or 16 antenna elements, and the specific number is not limited in this embodiment.
With continued reference to fig. 3, the antenna channel 301 has a beam receiving direction of a first beam direction 305, the antenna channel 302 has a beam receiving direction of a second beam direction 306, the antenna channel 303 has a beam receiving direction of a third beam direction 307, and the antenna channel 304 has a beam receiving direction of a fourth beam direction 308.
As further shown in fig. 7, after the terminal 103 is powered on, the terminal 103 searches for the base station 102, and the terminal 103 can determine the antenna channel located in the best coverage area of the beam signal of the base station 102, so that the antenna channel located in the best coverage area of the beam signal of the base station 102 can receive the signal with the highest signal quality sent by the base station 102. The antenna channels not located within the best coverage area of the base station 102 receive a weaker signal quality transmitted by the base station 102. In this embodiment, the signal transmitted and received between the terminal 103 and the base station 102 may be a millimeter wave directional beam signal.
Taking fig. 7 as an example, if the terminal 103 determines that the antenna channel located in the best coverage area of the base station 102 is the antenna channel 301, for example, the signal received by the antenna channel 301 has the highest signal quality, and the terminal 103 can communicate with the base station 102 through the antenna channel 301, so as to ensure that the terminal 103 has better receiving performance.
It should be noted that, as shown in fig. 7, an example of an antenna channel located in the best coverage area of the beam signal of the base station 102 is taken as an example for illustration, in other embodiments, a plurality of antenna channels located in the best coverage area of the beam signal of the base station 102 may be provided, and the present embodiment is not limited thereto.
As shown in fig. 8, in the process of communicating between the terminal 103 and the base station 102, as the terminal 103 is used, the quality of the signal received by the antenna channel 301 deteriorates when the terminal 103 rotates or moves, and as a result, the antenna channel 301 leaves the best coverage area of the base station 102, and the terminal 103 needs to detect the antenna channel located in the best coverage area of the base station 102 again.
Taking fig. 8 as an example, after the terminal detects that an antenna channel located in the best coverage area of the base station 102 is the antenna channel 303 after the terminal rotates or moves, and the quality of a signal transmitted by the base station 102 and received by the terminal 103 is the highest, the terminal determines that the antenna channel for communicating with the base station 102 is switched from the antenna channel 301 to the antenna channel 303, so as to ensure that the terminal 103 has better receiving performance.
In the process of communication between the terminal 103 and the base station 102, as the number of the antenna elements of the terminal 103 is increased, the power consumption of the terminal 103 is also increased, and the method for configuring the antenna channel provided by the application can effectively reduce the power consumption consumed in the process of communication between the terminal and the base station through the millimeter wave antenna.
The following describes in detail the specific implementation procedure of the method for configuring an antenna channel shown in this embodiment with reference to fig. 9:
step 901, the terminal receives a reference signal sent by the base station.
It should be clear that, in this embodiment, the number of antenna channels of the terminal is four for an exemplary description, and the specific number of antenna channels of the terminal is not limited in this embodiment.
The reference signal shown in this embodiment is explained as follows:
specifically, since the performance of the wireless communication system is greatly affected by the wireless channel, which is not fixed and predictable as a wired channel, in the wireless communication system, the base station transmits a Reference Signal (RS) to the terminal, and the terminal receives the RS, and then performs approximate estimation on the channel according to a channel estimation algorithm, thereby calculating the signal quality.
Reference signals are classified into the following categories according to different requirements: a cell-specific reference signal (CRS), a demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS).
In an LTE multiple-input multiple-output (MIMO) transmission mode, the CRS is used for performing channel estimation on a Physical Downlink Shared Channel (PDSCH) and a Physical Downlink Control Channel (PDCCH), where the PDSCH channel estimation value is used to demodulate data. The demodulation data has high requirement on the accuracy of the channel estimation value, so the CRS density in the PDSCH is high.
DMRS is a reference signal for a terminal and is therefore transmitted only within a resource block allocated to the terminal. The DMRS uses the same precoding matrix for precoding at the base station side and the data, so that the terminal can demodulate the data without knowing the precoding matrix.
The CSI-RS is mainly used for a terminal to acquire Channel State Information (CSI), has a low requirement on accuracy of channel estimation, and can reduce density and save more resources compared with the DMRS. In the 5G system, there are a CSI-RS for beamforming (beam) management and a CSI-RS for mobility management measurement in addition to a CSI-RS for acquiring a channel state.
The reference signal may also be a synchronization signal block (SS-block), which may be used for a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSs) carrying cell-level information.
More specifically, please refer to fig. 10 for a schematic diagram of CRS, DMRS and CSI-RS, where an abscissa of a coordinate system shown in fig. 10 represents a dimension in a time domain, and an ordinate represents a dimension in a frequency domain, where, for example, the coordinate system shown in fig. 10 includes 14 × 12 Resource Elements (REs), each RE lasts for 1 OFDM symbol in the time domain and 1 subcarrier in the frequency domain, and reference signals CRS, DMRS and CSI-RS in the coordinate system are distributed as shown in fig. 10.
Step 902, the terminal obtains the signal quality of the reference signal received by the target antenna channel.
Specifically, the target antenna channel shown in this embodiment is any one of at least one antenna channel of the terminal.
Optionally, the signal quality shown in this embodiment may refer to Reference Signal Receiving Power (RSRP) on a target antenna channel of the terminal. The RSRP is a received power of a CRS in a Resource Block (RB) of each traffic channel included in a data frame received by a target antenna channel of the terminal within a measurement bandwidth preset by the terminal, and the RSRP may reflect a strength of a CRS signal of a cell in which the terminal resides.
Optionally, the signal quality in this embodiment may also refer to a signal to interference signal to noise ratio (SINR), where the SINR refers to a ratio of the strength of the useful signal received by the target antenna channel to the strength of the received interference signal. It can be seen that the SINR of the target antenna channel reflects the reception quality of the reference signal, and the terminal can determine, through the SINR of the target antenna channel, that the higher the SINR of the target antenna channel is, the higher the probability of correctly mediating the received signal through the target antenna channel is, the better the channel environment is, and the higher the transmission rate is.
Optionally, the signal quality shown in this embodiment may also refer to a Received Signal Strength Indication (RSSI), where the RSSI refers to an average value of total received power on a pilot symbol in a measurement period within a measurement bandwidth preset by the terminal. Specifically, the RSSI reflects the total received power of the OFDM symbols of the CRS included in the signal received by the target antenna channel, and includes all powers of the useful signal, the cyclic prefix, the intra-cell interference, the adjacent-cell interference, the noise, and the like.
Optionally, the signal quality shown in this embodiment may also refer to LTE Reference Signal Reception Quality (RSRQ), and the terminal may calculate RSRQ according to the following formula;
and RSRQ is N RSRP/RSSI, wherein N is the RB number of the RSSI measurement bandwidth of the terminal.
The above description of the signal quality received by the target antenna channel is an optional example, and is not limited in this embodiment, as long as the signal quality can reflect the signal receiving performance of the target antenna channel.
Optionally, steps 901 to 902 shown in this embodiment are optional steps, and if the terminal already stores the signal quality received by each antenna channel that the terminal has, the process of obtaining the signal quality of each antenna channel shown in steps 901 to 902 does not need to be executed, and if the terminal does not store the signal quality received by each antenna channel that the terminal has, the process of obtaining the signal quality of each antenna channel shown in steps 901 to 902 needs to be executed.
For example, if the terminal is in the idle state and the terminal has already obtained the signal quality received by each antenna channel, the terminal does not need to execute steps 901 to 902 in the connected state, and if the terminal is in the idle state and does not obtain the signal quality received by each antenna channel, the terminal needs to execute steps 901 to 902 in the connected state.
Step 903, the terminal configures a first antenna channel for data communication.
The terminal shown in this embodiment may configure, by using the signal quality received by each antenna channel included in the terminal, the first antenna channel used for performing data communication, where the number of the first antenna channels configured by the terminal shown in this embodiment is at least one, and the specific number of the first antenna channels is not described in detail in this embodiment, and the following describes, by way of example, a specific process of configuring the first antenna channel by the terminal shown in this embodiment:
a first optional way for the terminal to configure the first antenna channel is as follows:
the terminal may configure the first antenna channel when determining the quality of the signals received by all the antenna channels included in the terminal, where the first antenna channel is an antenna channel with the best received signal quality among all the antenna channels included in the terminal, that is, as shown in this manner, the number of the first antenna channels configured by the terminal is one.
A second optional way for the terminal to configure the first antenna channel is as follows:
the terminal determines a target signal quality, wherein the target signal quality is the lowest signal quality meeting the communication requirement of the terminal, and the terminal can configure at least one first antenna channel.
Specifically, if the terminal determines that the signal quality received by one antenna channel of the terminal is greater than or equal to the target signal quality, the terminal may determine that the antenna channel whose received signal quality is greater than or equal to the target signal quality is the first antenna channel; if the terminal determines that the sum of the signal qualities received by the antenna channels of the terminal is greater than or equal to the target signal quality, the terminal can determine that the antenna channels are all the first antenna channel.
A third optional way for the terminal to configure the first antenna channel is as follows:
the terminal can generate an antenna channel list under the condition that the signal quality received by all antenna channels included by the terminal is configured, wherein the antenna channel list comprises the identifications of all antenna channels of the terminal, and all antenna channels included by the antenna channel list are sorted according to the sequence of the signal quality received by each antenna channel from large to small.
When the terminal acquires the antenna channel list, the terminal may determine that the antenna channels sorted in the first N bits of the antenna channel list are the first antenna channels, where N is a positive integer greater than or equal to 1 in this embodiment.
A fourth optional way for the terminal to configure the first antenna channel is as follows:
the terminal determines a plurality of preset antenna channels meeting a preset condition, which is exemplarily illustrated in this embodiment by taking the number of the preset antenna channels configured by the terminal as a plurality, where the preset condition is that the signal quality is SINR, and the SINR of the plurality of preset antenna channels is the same.
The terminal determines an undetermined list, the undetermined list comprises a plurality of antenna channel sets, and the terminal can determine the number of layers (layers) output by a target antenna channel set, wherein the target antenna channel set is any one of the plurality of antenna channel sets included in the undetermined list, and the target antenna channel set comprises at least one preset antenna channel in the plurality of preset antenna channels.
The number of layers output by the set of target antenna channels is illustratively described below:
in this embodiment, the data transmitted between the base station and the terminal is divided into different layers for transmission, and the number of layers output by the target antenna channel set refers to the number of layers into which data is divided in the transmission process when the terminal performs data transmission with the base station by using the target antenna channel set.
Specifically, the multiple antenna channel sets included in the pending list are sorted according to the priority of the output layer number from large to small, the terminal can determine the antenna channel set with the highest priority in the pending list, and the terminal determines that any antenna channel included in the antenna channel set with the highest priority is the first antenna channel.
For example, the terminal determines that the preset antenna channels are antenna channel 1, antenna channel 2, and antenna channel 3, and SINR of antenna channel 1, antenna channel 2, and antenna channel 3 is 13dB, where the antenna channel set 1 includes antenna channel 1 and antenna channel 2, and the number of output layers is 2, the antenna channel set 2 includes antenna channel 1 and antenna channel 3, and the number of output layers is 1, and because the number of output layers of the antenna channel set 1 is greater than or equal to the number of output layers of the antenna channel set 2, the terminal may determine that all the antenna channels included in the antenna channel set 1 are the first antenna channel, that is, the antenna channel 1 and the antenna channel 2 included in the antenna channel set 1 are the first antenna channel.
And 904, the terminal communicates with the base station through the first antenna channel.
Specifically, the reaching of the first antenna channel in this embodiment is specifically used for the terminal to receive the reference signal sent by the base station through the first antenna channel, and please refer to step 901 for a description of a specific process of receiving the reference signal, which is not described in detail specifically.
In this embodiment, when the terminal is in an idle state, the first antenna channel may be used for at least one of the following:
cell reselection, paging listening, reception of a broadcast message, message listening of a random access response message (MSG 2) of a contention-based Random Access Channel (RACH) procedure, Radio Resource Control (RRC) setup or reconstruction (MSG 4) message.
In this embodiment, when the terminal is in a connected state, the first antenna path may be further configured to perform at least one of the following processes, except that the first antenna path needs to perform all processes that the terminal is in an idle state:
channel estimation, synchronization, data demodulation, decoding, and the like.
It can be seen that the first antenna channel for data communication shown in this embodiment may be configured to receive a signal of a control channel, a signal of a traffic data channel, and a reference signal, so as to implement communication with the base station.
Step 905, the terminal configures a second antenna channel for reference signal reception.
In this embodiment, the specific number of the second antenna channels configured by the terminal is not limited, as long as the number of the configured second antenna channels is at least one, and the terminal shown in this embodiment has determined, through step 902, the signal quality of the reference signals received by all the antenna channels of the terminal, and in the case that the terminal has determined the first antenna channel, as long as the signal quality of the reference signals received by the second antenna channel determined by the terminal is lower than the signal quality of the reference signals received by the first antenna channel.
For example, the terminal may rank the signal qualities of the reference signals received by all antenna channels of the terminal in order from high to low, where the rank order is, for example, antenna channel 3, antenna channel 2, antenna channel 1, and antenna channel 4, and the terminal may configure antenna channel 3 as a first antenna channel and configure antenna channel 2 as a second antenna channel.
Specifically, in the case that the terminal configures the second antenna channel, the determined second antenna channel may receive the target reference signal according to the indication of the preset reference signal receiving condition.
First, the reference signal receiving condition is exemplarily described below, and the present embodiment does not limit the specific content included in the reference signal receiving condition, as long as the reference signal receiving condition can indicate the target reference signal, so that the second antenna channel of the terminal successfully receives the target reference signal according to the indication of the reference signal receiving condition.
Specifically, the reference signal receiving condition includes a target signal type and a plurality of receiving time periods that are sorted in order from front to back, in this embodiment, when the first antenna channel is used for data communication and the second antenna channel is used for reference signal reception, a time period during which the second antenna channel is turned on is a sum of all the receiving time periods, so that the second antenna channel of the terminal receives the target reference signal when the receiving time period arrives, and the target signal type is used to indicate a signal type of the target reference signal, so that the type of the reference signal received by the second antenna channel is the same as the target signal type, where the signal type includes one or more types.
More specifically, the second antenna channel of the terminal is in a closed state during a non-reception time period, that is, at the end of the reception time period, and the second antenna channel of the terminal is opened to receive the target reference signal only when the reception time period is reached.
Optionally, the second antenna channel shown in this embodiment may be periodically turned on, that is, the reference signal receiving condition includes a target period, that is, a time duration between any two adjacent receiving time periods is the target period, so that the second antenna channel may be periodically turned on according to the target period.
Optionally, the second antenna channel shown in this embodiment is not periodically turned on, that is, as long as the terminal determines that the receiving time period comes, the terminal turns on the second antenna channel, so that the second antenna channel in the on state receives the reference signal.
With respect to the first antenna channel, as shown in the above step, the first antenna channel of the terminal processes and receives control channel data (PDCCH), traffic channel data (PDSCH) and CSI-RS (channel state indicator reference signal) for channel quality status measurement, which are sent by the base station in addition to the reference signal sent by the base station, while the second antenna channel shown in this embodiment is turned on only in the determined receiving time period of the terminal for receiving the reference signal, and it can be seen that, in a unit time period (e.g., a period of 160ms,320ms,10240m or longer), the time period during which the first antenna channel is turned on is greater than or equal to the time period during which the second antenna channel is turned on.
For example, the base station sequentially transmits the reference signal in a first time period, a second time period, a third time period, and a fourth time period, and the first antenna channel configured by the terminal is in a normally open state, the first antenna channel receives the reference signal in the first time period, the second time period, the third time period, and the fourth time period, and the receiving time period corresponding to the second antenna channel configured by the terminal for receiving the reference signal is the second time period, the second antenna channel of the terminal is only opened in the second time period to receive the target reference signal, and the second antenna channel of the terminal is in a closed state in the rest of the time, so as to save the power consumption of the terminal.
Therefore, the time length for opening the first antenna channel of the terminal is greater than or equal to the time length for opening the second antenna channel of the terminal, and the second antenna channel is opened at intervals, so that the power consumption of the terminal is effectively saved.
To better understand the configuration process of the terminal for the reference signal receiving condition, the following description is given by taking specific examples:
for example, the terminal may configure the reference signal receiving condition according to a state in which the current terminal is located;
for example, if the terminal determines that the terminal is in an idle state, the terminal may determine that the signal type of the target reference signal is the SS-block, and the receiving time period for receiving the target reference signal may be configured to be in the order of seconds, for example, the duration of the receiving time period may be 1 second, or 4 seconds, or 8 seconds. The present embodiment does not limit the length of the specific duration of the receiving period, as long as the length of the receiving period can be greater than or equal to the length of a Discontinuous Reception (DRX) cycle of the terminal. The terminal is in the idle DRX cycle, and does not have the RRC connection and the dedicated resource of the user, and the terminal mainly monitors the paging channel and the broadcast channel in the DRX cycle.
For another example, if the terminal determines that the terminal is in a connected state, the terminal may obtain the user service rate, and the method for the terminal to obtain the user service rate may be that the terminal may cache user service data currently running by the terminal, and in a determined detection period, the terminal reads the data volume of the cached user service data, and a quotient of the obtained data volume of the user service data and the detection period is the user service rate.
Under the condition that the terminal acquires the user service rate, the terminal can judge whether the user service rate is greater than or equal to a preset threshold, if the user service rate is greater than or equal to the preset threshold, the service executed by the terminal is a high-rate service, the terminal can set the receiving time period to be in a millisecond level, and if the user service rate is less than or equal to the preset threshold, the service executed by the terminal is a low-rate service, the terminal can set the receiving time period to be in a hundred millisecond level.
The specific length of the receiving time period is not limited in this embodiment, as long as the length of the receiving time period and the size of the user service rate form an inverse correlation relationship, that is, when the user service rate is high, the duration of the receiving time period is short, and when the user service rate is low, the duration of the receiving time period is long.
Optionally, the terminal shown in this embodiment may determine the number of second antenna channels according to the user service rate, and this embodiment does not limit the number of second antenna channels, as long as the terminal determines that a positive correlation exists between the size of the user service rate and the number of second antenna channels, that is, when the user service rate is higher, the number of second antenna channels configured by the terminal is greater, and when the user service rate is lower, the number of second antenna channels configured by the terminal is less.
For another example, the terminal may obtain an angular velocity at which the terminal rotates, the terminal may determine whether the angular velocity at which the terminal rotates is greater than or equal to a preset threshold, if the angular velocity at which the terminal rotates is greater than or equal to the preset threshold, it is determined that the current environment at which the terminal is located changes rapidly, the terminal may set the receiving time period to a millisecond level, and if the angular velocity at which the terminal rotates is less than or equal to the preset threshold, it is determined that the current environment at which the terminal is located changes slowly, and the terminal may set the receiving time period to a hundred millisecond level.
The specific length of the receiving time period is not limited in this embodiment, as long as there is an inverse correlation between the length of the receiving time period and the magnitude of the angular velocity of the terminal rotation, that is, when the angular velocity of the terminal rotation is large, the duration of the receiving time period is short, and when the angular velocity of the terminal rotation is short, the duration of the receiving time period is long.
Optionally, the terminal shown in this embodiment may configure the number of second antenna channels according to an angular velocity of terminal rotation, and this embodiment does not limit the number of second antenna channels, as long as the terminal determines that there is a positive correlation between the magnitude of the angular velocity of terminal rotation and the number of second antenna channels, that is, the higher the angular velocity of terminal rotation is, the more the number of second antenna channels configured by the terminal is, and the lower the angular velocity of terminal rotation is, the less the number of second antenna channels configured by the terminal is.
For another example, the terminal may obtain the moving speed of the terminal, the terminal may determine whether the moving speed of the terminal is greater than or equal to a preset threshold, if the moving speed of the terminal is greater than or equal to the preset threshold, it indicates that the current environment of the terminal changes rapidly, the terminal may set the receiving time period to a millisecond level, and if the moving speed of the terminal is less than or equal to the preset threshold, it indicates that the current environment of the terminal changes slowly, and the terminal may set the receiving time period to a hundred millisecond level.
In this embodiment, the specific length of the receiving time period is not limited, as long as the length of the receiving time period and the magnitude of the terminal moving speed form an inverse correlation relationship, that is, when the terminal moving speed is high, the duration of the receiving time period is short, and when the terminal moving speed is short, the duration of the receiving time period is long.
Optionally, the terminal shown in this embodiment may configure the number of second antenna channels according to the moving speed of the terminal, and this embodiment does not limit the number of second antenna channels, as long as the terminal determines that a positive correlation exists between the magnitude of the moving speed of the terminal and the number of second antenna channels, that is, when the moving speed of the terminal is higher, the number of second antenna channels configured by the terminal is larger, and when the moving speed of the terminal is lower, the number of second antenna channels configured by the terminal is smaller.
For another example, when the terminal determines that the terminal is in a connected state, the terminal may determine the receiving time period and the target signal type according to quality of service (QoS), specifically, the higher the QoS requirement is determined by the terminal, the shorter the duration time period of the receiving time period is, more specifically, the higher the QoS requirement is, the higher the frequency that the terminal needs to measure the reference signal is, so that the duration time period of the receiving time period determined by the terminal is shorter.
For another example, if the terminal determines that the terminal is in an idle state, the terminal may determine that the number of the target signal types may be reduced, if the terminal may determine that the target signal type is only the CSI-RS, and if the terminal determines that the terminal is in a connected state and/or the terminal determines that the user traffic rate is high, the terminal may determine that the number of the target signal types may be increased, if the terminal may determine that the target signal type is at least one of a CRS, a DMRS, a CSI-RS, and an SS-block, or any combination thereof.
The reference signal receiving condition shown in this embodiment may also be used to indicate a signal length, a signal offset, and the like of the target reference signal, and is not limited in this embodiment as long as the reference signal receiving condition can indicate that the terminal receives the target reference signal.
Optionally, in the case that the terminal shown in this embodiment configures multiple second antenna channels, the terminal may determine the reference signal receiving conditions corresponding to different second antenna channels.
For example, in a case that the terminal determines a target second antenna channel, where the target second antenna channel is any one of a plurality of second antenna channels configured by the terminal, the terminal may determine that a reference signal receiving condition corresponding to the target second antenna channel is a target reference signal receiving condition, and the terminal may receive the target reference signal through the target second antenna channel according to an indication of the target reference signal receiving condition.
In this embodiment, the content indicated by the reference signal receiving condition corresponding to the different second antenna channels may be the same or different.
For example, taking the reference signal receiving condition as an example where the content included in the reference signal receiving condition is the multiple receiving time periods shown above, different second antenna channels may receive the target reference signal according to the indication of the corresponding reference signal receiving condition, and different second antenna channels may receive the target reference signal according to different receiving time periods.
Step 906, the terminal receives the target reference signal in the target receiving time period through the target second antenna channel.
The target second antenna channel shown in this embodiment is any one of at least one second antenna channel configured by the terminal, and the target second antenna channel is in an on state in the target receiving time period.
Specifically, the terminal may obtain a target reference signal receiving condition corresponding to the target second antenna channel to determine a plurality of receiving time periods included in the target reference signal receiving condition, and then the terminal determines one receiving time period included in the target reference signal receiving condition, that is, when the target receiving time period is reached, the terminal may receive the target reference signal through the target second antenna channel.
Specifically, the target receiving time period shown in this embodiment includes a starting time point and an ending time point, a duration between the starting time point and the ending time point is a duration of the target receiving time period, and when the terminal determines that the starting time point arrives, the terminal may receive the target reference signal in the target receiving time period through the target second antenna channel.
It can be seen that, in this embodiment, when the terminal determines a plurality of second antenna channels, the terminal may respectively determine the reference signal receiving conditions corresponding to the respective second antenna channels, and then the terminal may receive the target reference signal according to the indication of the reference signal receiving conditions corresponding to the second antenna channels.
Optionally, the terminal shown in this embodiment may open the target second antenna channel before the target receiving time period arrives, so that the target second antenna channel is in an open state when the target receiving time period arrives.
Step 907, the terminal closes the target second antenna channel.
Specifically, when the terminal shown in this embodiment determines that the target receiving time period ends, the terminal may close the second antenna channel, so that the closed second antenna channel does not receive the reference signal any more.
More specifically, when the terminal determines that the end time point of the target receiving time period is reached, the terminal may determine that the target receiving time period is ended, and the terminal may close the target second antenna channel.
Step 908, the terminal determines whether the second antenna channel meets the target condition, if yes, step 909 is executed, and if no, step 906 is executed again.
When the terminal determines that the target reference signal is received through the second antenna channel in the target receiving time period, the terminal may determine whether the second antenna channel meets the target condition, where the target condition is that a first signal quality is less than or equal to a second signal quality, the first signal quality is a signal quality of the reference signal received by the target first antenna channel in an on state, and the second signal quality is a signal quality of the reference signal received by the target second antenna channel in the on state.
Optionally, the terminal first determines that a target receiving time period included in a target reference signal receiving condition corresponding to the target second antenna channel is included, the terminal may obtain the signal quality received by the first antenna channel in the target receiving time period and the signal quality received by the second antenna channel in the target receiving time period, and the terminal obtains the signal quality received by the second antenna channel and obtains the signal quality received by the first antenna channel in a specific calculation process, which is shown in step 902 for details, and the specific calculation process is not described again.
And when the terminal judges that the first signal quality is less than or equal to the second signal quality in the target receiving time period, the terminal switches an antenna channel for data communication from the first antenna channel to the second antenna channel.
The first signal quality shown in this embodiment is the signal quality of the reference signal received by the terminal in any target time period, for example, the target time period may be the target receiving time period shown above, and for example, the target time period may be any time period before the target receiving time period, and for example, the target time period may be any time period partially overlapping the target receiving time period, the duration of the target time period is not limited in this embodiment, i.e. the duration of the target time period may be equal to the duration of the target reception time period, or the duration of the target time period may be greater than or equal to the duration of the target receive time period, or the duration of the target time period may be less than or equal to the duration of the target receive time period.
For better understanding of this step, the following is exemplarily described with reference to a specific application scenario, and the terminal has an antenna channel 1, an antenna channel 2, an antenna channel 3, and an antenna channel 4 as an example:
the terminal determines, based on the quality of signals received by the four antenna channels, that an antenna channel 1 of the terminal is located in an optimal coverage area of a beam signal of a base station, and then the terminal may configure a first antenna channel for data communication as an antenna channel 1 and may also configure a second antenna channel for reference signal reception as an antenna channel 3, where the specific determination process is shown in the above step and is not described in detail;
as time goes by, the terminal may rotate or move, and in the target receiving time period, the antenna channel 1 is no longer located in the optimal coverage area of the base station beam signal, and the signal quality of the antenna channel 1 detected by the terminal in the target time period is lower than the signal quality of the antenna channel 3, at this time, the antenna channel located in the optimal coverage area of the base station beam signal is switched from the antenna channel 1 to the antenna channel 3, and the terminal may configure an antenna channel for data communication and switch from the antenna channel 1 to the antenna channel 3.
It can be seen that, in this embodiment, in the case that the terminal determines that the second antenna channel meets the target condition, step 909 needs to be executed to perform the switching process of the antenna channel.
There is no restriction on the execution timing between step 907 and step 908 in this embodiment.
Step 909, the terminal configures the second antenna channel for data communication.
In this embodiment, when the terminal determines that the second antenna channel meets the target condition, it indicates that the first antenna channel currently used for data communication is no longer located in the optimal coverage area of the base station beam signal, and if the terminal performs communication through the first antenna channel that is no longer located in the optimal coverage area of the base station beam signal, the communication requirement of the terminal cannot be met, the terminal may switch the antenna channel used for data communication to the second antenna channel that is located in the optimal coverage area of the base station beam signal.
Optionally, in the case that the terminal shown in this embodiment determines that the first antenna channel has left the best coverage area of the base station beam signal, the terminal may determine whether the signal quality received by the first antenna channel is greater than or equal to a target threshold, where the size of the target threshold is not limited in this embodiment, as long as the terminal may configure the first antenna channel for measurement when the signal quality received by the first antenna channel is greater than or equal to the target threshold, and the terminal may determine that the first antenna channel does not participate in receiving the reference signal when the signal quality received by the first antenna channel is less than or equal to the target threshold.
By adopting the method shown in this embodiment, the terminal determines that the antenna channel with the highest received signal quality performs communication, so that the terminal can effectively receive high-quality signals, and effectively ensures the communication quality of the terminal, while the antenna channel configured for reference signal reception is in a periodically opened state, the antenna channel configured for reference signal reception performs reference signal reception only when the configured reception time period arrives, so that the power consumption of the terminal is reduced, and when the communication environment of the terminal shown in this embodiment changes, for example, after the terminal moves and/or rotates, the terminal can reconfigure the antenna channel configured for data communication, so that even if the communication environment of the terminal changes, the terminal communicates with the base station through the switched antenna channel for data communication, therefore, the situation that the signal is poor due to the change of the communication environment of the terminal is avoided, and the quality of the signal received by the terminal is effectively guaranteed, so that the method shown in the embodiment can be well adapted to the communication of the millimeter wave band, and can be quickly adapted to the change of the environment and the change of the received wave beam.
Based on fig. 11, the following is a specific process of how to perform the method for configuring the antenna channel when the terminal shown in this embodiment is in the idle state:
in step 1101, the terminal receives a reference signal transmitted by the base station.
Step 1102, the terminal obtains the signal quality of the reference signal received by the target antenna channel.
Specifically, when the terminal shown in this embodiment is in an idle state, the terminal may calculate the signal quality received by the target antenna channel according to the reference signal SS-block.
Step 1103, the terminal configures a first antenna channel for data communication.
For details of the specific execution process from step 1101 to step 1103 shown in this embodiment, please refer to step 901 to step 903 shown in fig. 9, which is not described in detail in this embodiment.
Optionally, the terminal shown in this embodiment may adjust the first antenna channel according to an angular velocity at which the terminal rotates, and the terminal may obtain the angular velocity at which the terminal rotates, and when it is determined that the angular velocity at which the terminal rotates increases, the number of the first antenna channels may be increased, and when it is determined that the angular velocity at which the terminal rotates decreases, the number of the first antenna channels may be decreased.
Specifically, the four antenna channels of the terminal specifically include an antenna channel 1, an antenna channel 2, an antenna channel 3, and an antenna channel 4, and the example is illustrated with the first antenna channel configured for the terminal as the antenna channel 1 and the antenna channel 3:
the terminal may obtain an angular velocity at which the terminal rotates, and when it is determined that the angular velocity at which the terminal rotates increases, the number of the first antenna channels may be increased, for example, the terminal may determine that the first antenna channels are changed from the antenna channel 1 and the antenna channel 3 to the antenna channel 1, the antenna channel 2, and the antenna channel 3.
The number of the first antenna channels may be decreased when it is determined that the angular velocity of the terminal rotation is decreased, e.g., the terminal may determine that the first antenna channel is changed from antenna channel 1 and antenna channel 3 to antenna channel 1.
Optionally, the terminal shown in this embodiment may adjust the first antenna channel according to the moving speed of the terminal, and the terminal may obtain the moving speed of the terminal, and when it is determined that the moving speed of the terminal is increased, the number of the first antenna channels may be increased, and when it is determined that the moving speed of the terminal is decreased, the number of the first antenna channels may be decreased.
Specifically, the four antenna channels of the terminal specifically include an antenna channel 1, an antenna channel 2, an antenna channel 3, and an antenna channel 4, and the example is illustrated with the first antenna channel configured by the terminal for performing data communication as the antenna channel 1 and the antenna channel 3:
the terminal may obtain a moving speed of the terminal, and when it is determined that the moving speed of the terminal is increased, the number of the first antenna channels may be increased, for example, the terminal may determine that the first antenna channel is changed from the antenna channel 1 and the antenna channel 3 to the antenna channel 1, the antenna channel 2, and the antenna channel 3.
When the terminal is determined to have a reduced moving speed, the number of the first antenna channels may be reduced, for example, the terminal may determine that the first antenna channel is changed from antenna channel 1 and antenna channel 3 to antenna channel 1.
Optionally, under the condition that the terminal is configured with at least one first antenna channel, the terminal may further determine a target first antenna element that needs to be turned on in the target first antenna channel, where the target first antenna channel is any one of the at least one first antenna channel determined by the terminal, specifically, any one first antenna channel that the terminal has multiple antenna elements, for example, the first antenna channel has 8 or 16 antenna elements, and the target first antenna element is any one of the antenna elements that the target first antenna channel has and needs to be turned on in the communication process, and this embodiment does not limit the number of the target first antenna elements that are turned on by any one first antenna channel.
For example, if the terminal determines the number of target first antenna elements that the target first antenna channel needs to be turned on, the terminal may obtain a target signal quality, where the target signal quality is the lowest signal quality that meets the communication requirement of the terminal, and the terminal may determine at least one target first antenna element, so that the sum of the signal qualities of the reference signals received by all the target first antenna elements is greater than or equal to the target signal quality.
For example, the first antenna channel includes 8 antenna elements, specifically, an antenna element 1, an antenna element 2, an antenna element 3, an antenna element 4, an antenna element 5, an antenna element 6, an antenna element 7, and an antenna element 8.
The terminal determines that the sum of the signal qualities received by the antenna oscillator 1, the antenna oscillator 2, the antenna oscillator 3, the antenna oscillator 4 and the antenna oscillator 5 is greater than or equal to the target signal quality, and also determines that the sum of the signal qualities received by the antenna oscillator 6 and the antenna oscillator 8 is also greater than or equal to the target signal quality, so that the terminal can determine that the antenna oscillator 6 and the antenna oscillator 8 are the target first antenna oscillator, therefore, under the condition that the terminal communicates through the configured target first antenna oscillator, the communication requirement of the terminal can be guaranteed, and the power consumption of the terminal can be reduced.
Optionally, when the terminal shown in this embodiment detects that the communication requirement of the terminal changes, the terminal may increase or decrease the number of the target first antenna oscillators, so that the terminal meets the communication requirement while reducing the power consumption of the terminal.
In this embodiment, a specific number of the target first antenna elements determined by the terminal is not limited, as long as the sum of signal qualities of all the target first antenna elements is greater than or equal to the target signal quality when the terminal turns on all the determined target first antenna elements, and a specific description of the target signal quality refers to the embodiment shown in fig. 9, which is not limited in this embodiment.
And 1104, the terminal communicates with the base station through the first antenna channel.
Please refer to step 904 shown in fig. 9, for a specific execution process of step 1104 shown in this embodiment, which is not described in detail in this embodiment.
Step 1105, the terminal configures a second antenna channel for reference signal reception.
When the terminal determines that the terminal is currently in the idle state, the terminal may determine the reference signal receiving condition corresponding to the idle state, and a specific process of the terminal determining the reference signal receiving condition corresponding to the idle state is please see step 905 shown in fig. 9 in detail, which is not described in detail in this embodiment.
Optionally, in this embodiment, the terminal may adjust the second antenna channel according to a change of a communication environment in which the terminal is currently located.
The specific process of the terminal adjusting the second antenna channel according to the communication environment can refer to the specific process of the terminal adjusting the first antenna channel according to the communication environment shown in step 1103, and is not limited in this embodiment.
Optionally, under the condition that the terminal configures at least one second antenna channel, the terminal may further determine a target second antenna element that needs to be turned on in the target second antenna channel, where the terminal determines an explanation of the antenna element that is turned on by the second antenna channel, please refer to the above-indicated explanation of the antenna element that is turned on by the terminal, which is not described in detail.
Step 1106, the terminal receives the target reference signal in the target receiving time period through the target second antenna channel.
For a specific implementation procedure of step 1106 shown in this embodiment, please refer to step 906 shown in fig. 9 in detail, which is not limited in this embodiment specifically, in order to better understand a specific procedure that the terminal receives the target reference signal through the second antenna channel shown in this embodiment of the present invention, the following description is made with reference to an application scenario shown in fig. 12:

The terminal can determine according to the reference signal receiving condition corresponding to the antenna channel 1, and the terminal receives the target reference signal every 80ms through the antenna channel 1. And the signal type of the target reference signal is SS-block. Specifically, the terminal receives the subframe in which the target receiving time period of the target reference signal through the antenna channel 1 is subframe number modulo 80 and 0, starting with 3 symbols of SS-block in the 1 st slot (slot), that is, the terminal only needs to receive 3 OFDM symbols therein every 80ms through the antenna channel 1.
The terminal configures an antenna channel 2 for reference signal reception, a target period included in a reference signal reception condition corresponding to the antenna channel 2 is 160ms, and the reference signal reception condition corresponding to the antenna channel 2 may further include a target reception time period, where the target reception time period is used to indicate a time period for the antenna channel 2 to receive the target reference signal.
The terminal can determine according to the reference signal receiving condition corresponding to the antenna channel 2, and the terminal receives the target reference signal once every 160ms through the antenna channel 2. And the signal type of the target reference signal is SS-block. Specifically, the terminal receives the subframe in which the target receiving time period of the target reference signal through the antenna channel 2 is subframe number modulo 160 and 0, starting with 3 symbols of SS-block in 1 st slot, that is, the terminal only needs to receive 3 OFDM symbols therein every 160ms through the antenna channel 1.
The target period of the antenna channel 3 configured by the terminal is infinite, so that the antenna channel 3 of the terminal does not participate in receiving the measurement signal, namely, the antenna channel 3 of the terminal is always in a closed state in the process of communication between the terminal and the base station, and the power consumption of the terminal is saved.
Step 1107, the terminal closes the target second antenna channel.
Specifically, when the terminal shown in this embodiment determines that the target receiving time period ends, the terminal may close the second antenna channel, so that the closed second antenna channel does not receive the reference signal any more.
