Description

Method for controlling terminal uplink control channel transmission mode, transmission method and equipment

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, and a computer program product for controlling a terminal uplink control channel transmission mode.

Background

The main frequency band adopted by 5G is higher than that adopted by 4G, so that the problem of insufficient uplink coverage exists. Taking the example that 5G adopts a 3.5GHz frequency band and 4G adopts a 2.6GHz frequency band, from the simulation result, when the terminal adopts single antenna for transmission and the transmission power is 23dBm, the uplink coverage of the 3.5GHz frequency band is reduced by about 5dB compared with the uplink coverage of the 2.6GHz frequency band. If the terminal adopts dual-antenna transmission and the total transmission power is 26dBm, the uplink coverage of the 3.5GHz frequency band can be effectively improved by 3-5dB, which is respectively reflected in that the 3dB gain of the transmission power is improved and the transmission diversity gain which can be obtained is about 2dB, and the result is that the uplink coverage effect is equivalent to 2.6 GHz. Therefore, the design of the 5G terminal needs to consider the support of dual-antenna and high-power (total transmission power is 26dBm) transmission for uplink to enhance uplink coverage. Meanwhile, uplink multi-antenna transmission can also effectively improve the uplink transmission rate. Currently, 3GPP Rel-15 defines a spatial multiplexing transmission method for a Physical Uplink Shared Channel (PUSCH), and multiple streams of data can be transmitted by using multiple ports. Therefore, the current specification of 5G terminals requires that the terminal support at least two uplink transmit antennas and be able to support the maximum overall transmit Power of 26dBm, and the 3GPP standard has defined the maximum transmit Power of 26dBm as the terminal capability Class 2(UE Power Class 2). At present, the implementation schemes of the 5G terminal for implementing high-power transmission mainly include two schemes, one scheme is that the terminal supports uplink two-antenna transmission, each antenna supports the maximum transmission power of 23dBm, that is, the total transmission power of the terminal is 26dBm implemented by the dual-transmission antenna 23dBm +23 dBm; the other is that the terminal supports uplink two-antenna transmission, one or two antennas support the maximum transmission power of 26dBm, that is, the terminal has the capability of single-antenna maximum transmission power reaching 26 dBm.

However, for the uplink control channel: physical Uplink Control Channel (PUCCH) and Physical Random Access Channel (PRACH), 3GPP Rel-15 only defines single port transmission, and transmission diversity transmission methods such as Space Frequency Block Code (SFBC) and Time domain precoder cycling (Time domain precoder) which require an increase in demodulation reference signal (DMRS) overhead are not included in the Rel-15 standardization. This means that the terminal may only use a single antenna transmission method, and cannot obtain high power and transmit diversity gain, which may cause limitation of uplink control channel (e.g. PRACH), thereby affecting the coverage of the cell. Therefore, the technical specification of the current 5G terminal requires that the terminal supports the uplink control channel to adopt the maximum transmission power of 26dBm, and can adopt a single-antenna implementation scheme of 26dBm transmission or a dual-antenna implementation scheme of 23dBm +23dBm transmission. For a dual-antenna transmission scheme, a terminal can adopt a Cyclic Delay Diversity (CDD) or a precoding-like transmission Diversity mode, which is transparent to a protocol and realized by the terminal itself, and may obtain additional transmission Diversity gain on the basis of high-power transmission, thereby further improving an uplink coverage.

However, although the 5G terminal adopts the uplink dual-antenna transmission scheme, which may increase the uplink transmission rate and enhance uplink coverage, the problem of high Power consumption of the terminal may also be caused when two Power Amplifiers (PAs) operate simultaneously. Especially in the cell center, when the terminal mainly performs downlink data transmission and the uplink is mainly used for control signaling transmission, the dual-antenna transmission scheme of the uplink control channel may bring unnecessary power consumption.

Therefore, how to reasonably select the transmission mode of the uplink control channel of the terminal and achieve effective balance between the uplink coverage performance and the power consumption of the terminal is a technical problem to be solved urgently at present.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling a terminal uplink control channel transmission mode according to an embodiment of the present invention, where the method is applied to a network side device, and includes the following steps:

step 11: receiving an uplink signaling sent by a terminal, wherein the uplink signaling comprises an uplink control channel transmitting mode which can be supported by the terminal;

step 12: measuring an uplink channel of the terminal to acquire quality information of the uplink channel;

step 13: determining a transmitting mode of the terminal uplink control channel according to the uplink signaling, the quality information and a preset quality threshold;

step 14: and sending a first message to the terminal, wherein the first message is used for indicating the terminal to adjust the transmission mode adopted by the current uplink control channel to the transmission mode determined by the network side equipment.

The method for controlling the terminal uplink control channel transmission mode provided by the embodiment of the invention can ensure that the terminal transmission mode on the uplink control channel is more reasonable, can effectively balance uplink coverage performance, terminal power consumption and processing complexity, and reduces the terminal power consumption and the processing complexity while ensuring uplink transmission quality to meet the coverage requirement.

Preferably, the terminal comprises a first antenna and a second antenna;

That is, the terminal supports a single-antenna transmission mode and a dual-antenna transmission mode on the uplink control channel, and the network side device determines the number of the transmission antennas used by the terminal on the uplink control channel.

In the embodiment of the present invention, the uplink signaling sent by the terminal may be a terminal Capability (UE Capability) signaling, and in the terminal Capability signaling, an uplink control channel transmission mode that can be supported by the terminal may include a terminal transmission Power Class (UE-Power Class), which indicates a transmission Power Class supported by the terminal, for example: UE Power Class2 indicates a maximum transmit Power of the terminal of 26 dBm.

Optionally, the maximum transmission power of the first antenna and the maximum transmission power of the second antenna are both a first preset power threshold; or, the maximum transmitting power of the first antenna is a second preset power threshold, the maximum transmitting power of the second antenna is a first preset power threshold or a second preset power threshold, and the second preset power threshold is greater than the first preset power threshold.

Specifically, the uplink control channel transmission modes that the terminal can support may further include what mode the terminal can achieve high power transmission. For example: uplink signaling (such as terminal capability signaling) sent by the terminal may include a field for indicating how the terminal implements high power transmission. For example: the first predetermined power threshold is 23dBm and the second predetermined power threshold is 26 dBm. The field is 0, which indicates that the terminal supports 23dBm +23dBm of dual transmitting antennas in an uplink control channel (that is, the maximum transmitting power of the first antenna and the maximum transmitting power of the second antenna are both 23dBm of the first preset power threshold), and the maximum total transmitting power of the terminal is 26 dBm. The field is set to be 1, which indicates that the terminal supports dual-antenna transmission on the uplink control channel, the maximum total transmission power of the terminal is 26dBm, and the terminal has the capability of single-antenna maximum transmission power of 26dBm (that is, the maximum transmission power of at least 1 antenna in the first antenna and the second antenna is 26 dBm).

In the embodiment of the present invention, the network side device may obtain the quality information of the uplink channel of the corresponding terminal through uplink channel (including but not limited to uplink control channel) measurement. The detected quality information of the uplink channel may include at least one of: the information indicative of Channel Quality (CQI), Signal to Interference plus Noise Ratio (SINR).

The network side device may preset one or more threshold values of the quality of the uplink channel, compare the detected quality information of the uplink channel with the preset threshold values, and further determine the transmission scheme of the terminal of the corresponding type on the uplink control channel.

the preset quality threshold comprises a first preset quality threshold;

Specifically, the maximum transmitting power of a first antenna and the maximum transmitting power of a second antenna of the terminal are both a first preset power threshold value of 23dBm, a threshold value of uplink channel quality preset by the network side equipment is a first preset quality threshold value M, and if the quality information of the uplink channel detected by the network side equipment is greater than or equal to (or greater than) M, the transmitting mode of the terminal is determined to be a single-antenna transmitting mode; and if the quality information is less than (or less than or equal to) M, determining that the transmission mode of the terminal is a dual-antenna transmission mode.

That is, when the uplink channel quality of the terminal is good (for example, the terminal is in the center of a cell), the network side device determines that the terminal adopts a single-antenna transmission mode on the uplink control channel, so that the energy consumption of the terminal can be saved, and the uplink transmission quality can be ensured to meet the coverage requirement; when the uplink channel quality of the terminal is poor (for example, the terminal is at the edge of a cell), the network side equipment determines that the terminal adopts a dual-antenna transmission mode in the uplink control channel, so that the uplink transmission quality can be ensured to meet the coverage requirement, and the uplink transmission rate can be effectively improved.

Specifically, the maximum transmission power of the first antenna of the terminal is the second preset power threshold 26dBm, and the maximum transmission power of the second antenna is the second preset power threshold 26dBm or the first preset power threshold 23 dBm. The threshold value of the uplink channel quality preset by the network side equipment is a first preset quality threshold value M and a second preset quality threshold value N.

And if the quality information of the uplink channel detected by the network side equipment is greater than or equal to (or greater than) M, determining that the transmission mode of the terminal is a single-antenna transmission mode in which the first antenna or the second antenna is adopted for transmission. That is, when the uplink channel quality of the terminal is good, the network side device determines that the terminal transmits in the uplink control channel by using any one of the first antenna and the second antenna, so as to control the transmission power of the uplink control channel to be less than or equal to 23 dBm.

And if the quality information is less than (or less than or equal to) M and greater than or equal to (or greater than) N, determining that the transmission mode of the terminal is a single-antenna transmission mode in which the antenna with the maximum transmission power of 26dBm is adopted for transmission. That is to say, when the uplink channel quality of the terminal is general, the network side device needs to schedule the terminal to transmit power in the uplink control channel within the interval (23dBm, 26dBm), if the maximum transmit power of the first antenna and the second antenna of the terminal is 26dBm, the network side device determines that the terminal uses any one of the first antenna and the second antenna to transmit in the uplink control channel, and if the maximum transmit power of the first antenna of the terminal is 26dBm and the maximum transmit power of the second antenna is 23dBm, the network side device determines that the terminal uses the first antenna to transmit in the uplink control channel.

And if the quality information is less than (or less than or equal to) N, determining that the transmission mode of the terminal is a dual-antenna transmission mode. That is, when the quality of the uplink channel of the terminal is poor, the network side device determines that the terminal adopts a dual-antenna transmission mode on the uplink control channel, and controls the transmission power of the uplink control channel to be equal to 26 dBm.

Therefore, in the embodiment of the invention, the network side equipment can fully consider the type of the terminal and flexibly select the number of the transmitting antennas of the terminal on the uplink control channel (PUCCH, PRACH). For example: aiming at a terminal supporting uplink control channel dual-antenna transmission (the maximum transmission power of each antenna is 23dBm), and a terminal supporting uplink control channel dual-antenna transmission and having single-antenna maximum transmission power of 26dBm (the maximum transmission power of at least one antenna is 26dBm), different transmission schemes are determined aiming at different types of terminals, and the method has the advantages of pertinence and accordance with the working characteristics of the different types of terminals.

Optionally, the determining that the transmission mode of the uplink control channel of the terminal is the single-antenna transmission mode, and the first message is used to indicate that the number of antenna ports used by the terminal for transmitting the uplink control channel is 1.

That is, the network side device indicates the terminal to use the single antenna transmission mode in the uplink control channel by indicating the number of the antenna ports to the terminal to be 1.

Optionally, the determining that the transmission mode of the uplink control channel of the terminal is the dual-antenna transmission mode, and the first message is used to indicate that the number of antenna ports used by the terminal for transmitting the uplink control channel is 2.

That is, the network side device indicates the terminal to use the dual-antenna transmission mode in the uplink control channel by indicating the number of the antenna ports to the terminal to be 2.

Optionally, the determining that the transmission mode of the uplink control channel of the terminal is the dual-antenna transmission mode, and the first message is used to instruct the terminal to transmit a diversity transmission mode that starts CDD or precoding on the uplink control channel.

That is to say, the network side device may instruct the terminal to use a dual-antenna transmission method in the uplink control channel by instructing the terminal to use a small-scale CDD or a diversity transmission method such as precoding. Moreover, by adopting the diversity transmission mode, the method is transparent to the protocol and realized by the terminal, and can obtain additional transmission diversity gain on the basis of high-power transmission, thereby further improving the uplink coverage.

For a terminal supporting uplink control channel dual-antenna transmission and having single-antenna maximum transmission power of 26dBm (the maximum transmission power of at least one antenna is 26dBm), determining that the transmission mode of the uplink control channel of the terminal is a dual-antenna transmission mode, and instructing the terminal to start diversity transmission modes such as CDD (code division multiple access) or precoding and the like in the uplink control channel transmission, so that the communication quality can be further ensured, and the uplink coverage performance can be improved.

Preferably, the first message is a Radio Resource Control (RRC) Reconfiguration message (RRC Reconfiguration).

Specifically, a field may be added in the RRC reconfiguration message, where the field is used for a network side device to indicate the number of antenna ports used for terminal uplink control channel transmission or whether CDD or a precoding diversity transmission mode needs to be turned on for terminal uplink control channel transmission.

The feedback message may be an RRC Reconfiguration Complete message (RRC Reconfiguration Complete).

Specifically, a field may be added to the RRC reconfiguration complete message for the terminal to feedback that the transmission mode of the uplink control channel has been adjusted.

In some preferred embodiments of the present invention, the first message is used to instruct the terminal to use a dual-antenna transmission mode on the uplink control channel;

That is, the network side device presets a measurement duration (i.e., a preset duration) and a demodulation performance threshold (i.e., a preset gain threshold) of the uplink control channel. For a terminal supporting uplink control channel dual-antenna transmission and supporting single-antenna maximum transmit power of 26dBm (i.e., the maximum transmit power of one of the first antenna and the second antenna of the terminal is 26dBm, and the maximum transmit power of the other antenna is 23 dBm). When the network side equipment determines that the terminal adopts a dual-antenna transmission mode on the uplink control channel and indicates the terminal to complete the adjustment of the uplink control channel transmission mode, the network side equipment detects the demodulation performance of the uplink control channel within the preset measurement time length to obtain the demodulation performance gain of the uplink control channel when the uplink control channel adopts the dual-antenna transmission mode compared with the demodulation performance gain of the uplink control channel when the uplink control channel adopts the single-antenna transmission mode. If the demodulation performance gain is greater than or equal to the preset gain threshold, the network side equipment judges that the uplink control channel of the terminal keeps the dual-antenna transmission mode, if: the terminal adopts a CDD or precoding and other transmission diversity transmission processing modes; otherwise, the network side device determines that the terminal uplink control channel adopts a single antenna transmission mode, such as: and switching the dual-antenna transmission mode of the terminal on the uplink control channel into single-antenna transmission with the maximum transmission power of 26 dBm.

Referring to fig. 2, fig. 2 is a flow chart illustrating a process for determining an uplink control channel transmission mode in an exemplary application scenario of the present invention. In this specific application scenario, the terminal UE1 is a terminal supporting dual-antenna transmission for an uplink control channel, and the maximum transmission power of the first antenna and the maximum transmission power of the second antenna are both 23 dBm. The procedure for determining the UE1 uplink control channel transmission mode is as follows:

2.1, the UE1 sends an uplink signaling to the network side device, where the uplink signaling is used to report the capability information of the terminal.

The uplink signaling is used to report an uplink control channel transmission mode that the UE1 can support, and specifically includes a power class of the UE1 and an implementation scheme that the UE1 supports high power transmission on the uplink control channel.

2.2, the network side equipment acquires the quality information of the uplink channel of the UE 1.

2.3, the network side device determines whether the obtained quality information of the uplink channel of the UE1 is greater than a first preset quality threshold M, if so, turns to 2.4, and if not, turns to 2.5.

2.4, the network side equipment determines that the transmission mode of the UE1 uplink control channel is a single-antenna transmission mode.

2.5, the network side equipment determines that the transmission mode of the UE1 uplink control channel is a dual-antenna transmission mode.

2.6, the network side equipment sends downlink signaling to the UE1, indicating the UE1 to transmit on the uplink control channel by using the transmission mode determined by the network side equipment.

Referring to fig. 3, fig. 3 is a flow chart illustrating a process for determining an uplink control channel transmission mode in another embodiment of the present invention. In this specific application scenario, the terminal UE2 is a terminal supporting dual-antenna transmission of an uplink control channel, and the maximum transmission power of at least one of the two antennas is 26 dBm. The procedure for determining the UE2 uplink control channel transmission mode is as follows:

3.1, the UE2 sends an uplink signaling to the network side device, and the uplink signaling is used for reporting the capability information of the terminal.

The uplink signaling is used to report an uplink control channel transmission mode that the UE2 can support, and specifically includes a power class of the UE2 and an implementation scheme that the UE2 supports high power transmission on the uplink control channel.

3.2, the network side equipment acquires the quality information of the uplink channel of the UE 2.

3.3, the network side device determines whether the obtained quality information of the uplink channel of the UE2 is greater than a first preset quality threshold M, if not, turns to 3.4, and if so, turns to 3.5.

And 3.4, the network side equipment judges whether the acquired quality information of the uplink channel of the UE2 is smaller than a second preset quality threshold value N, if not, the step is switched to 3.5, and if so, the step is switched to 3.6.

3.5, the network side equipment determines that the transmission mode of the UE2 uplink control channel is a single-antenna transmission mode.

That is, the quality information is greater than M, and the network side device determines that the UE2 uses a single antenna transmission mode (for example, uses any one of two antennas to transmit) on the uplink control channel. Or, the quality information is less than or equal to M and greater than N, and the network side device determines that the UE2 uses a single antenna transmission method (for example, uses a single antenna with a maximum transmission power of 26dBm for transmission) in the uplink control channel.

3.6, the network side device obtains the demodulation performance gain of the UE2 uplink control channel by adopting a dual-antenna transmission mode compared with a single-antenna transmission mode, and determines whether the demodulation performance gain is greater than a preset gain threshold, if not, turns to 3.5, and if so, turns to 3.7.

That is, the quality information is less than or equal to N, the network side device determines that the transmission mode of the uplink control channel of the UE2 is a dual-antenna transmission mode, and obtains a demodulation performance gain of the UE2 in the dual-antenna transmission mode compared with the single-antenna transmission mode within a preset time period.

3.7, the network side equipment determines that the transmission mode of the UE2 uplink control channel is a dual-antenna transmission mode.

If the demodulation performance gain is greater than the preset gain threshold, the network side device determines that the UE2 maintains the dual-antenna transmission mode in the uplink control channel, otherwise, the network side device determines that the UE2 switches the dual-antenna transmission mode to the single-antenna transmission mode in the uplink control channel (turn to 3.4).

3.8, the network side equipment sends downlink signaling to the UE2, and instructs the UE2 to transmit on the uplink control channel by adopting the transmission mode determined by the network side equipment.
