Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a channel control method, apparatus, and device for millimeter-wave systems. Background Art

[0002] Currently, 5G NR (5G New Radio, the global 5G standard) millimeter-wave systems are usually restricted by analog device constraints, and the same analog beam can only be transmitted across the entire frequency band of the same Orthogonal Frequency Division Multiplexing (OFDM) symbol.

[0003] To make full use of analog beam resources, millimeter-wave systems usually use a short format of PUCCH (Physical Uplink Control Channel) to feedback uplink control information (UCI). When the station spacing is large, due to the limited coverage of the short format of PUCCH, the feedback information sent by the user terminal at the middle and far points to the base station cannot be obtained by the base station, and the base station will repeatedly obtain feedback information from the terminal, resulting in a high retransmission rate of the Physical Downlink Shared Channel (PDSCH). The retransmitted data occupies the space of the remaining valid data, reducing the data transmission efficiency of the system; moreover, the bit error rate of the UCI of the user terminal at the middle and far points increases, further increasing the bit error rate of the downlink shared channel and impairing the downlink capacity of the system.

Among them, the described embodiments are some but not all of the embodiments of the present application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more than two.

[0094] Currently, millimeter wave systems are usually restricted by analog device constraints, and the same analog beam can only be transmitted across the entire frequency band of the same orthogonal frequency division multiplexing (OFDM) symbol.

[0095] To make full use of analog beam resources, millimeter-wave systems usually use short-form PUCCH to feedback uplink control information (UCI for short). When the cell spacing is large, due to the limited coverage of short-form PUCCH, the feedback information sent by user terminals at medium and far distances to the base station cannot be acquired by the base station. The base station will repeatedly request feedback information from the terminal, resulting in a high retransmission rate of the physical downlink shared channel (PDSCH for short). The retransmitted data occupies the space of the remaining valid data, reducing the data transmission efficiency of the system. Moreover, the UCI error rate of user terminals at medium and far distances increases, further increasing the error rate of the physical downlink shared channel and impairing the downlink capacity of the system.

[0096] In summary, how to efficiently and accurately control the channel to ensure that the capacity of the millimeter-wave system is not impaired is an urgent problem to be solved.

[0097] In view of this, the present application provides a channel control method, device and equipment for a millimeter-wave system to solve the problem of impaired downlink capacity of the millimeter-wave system caused by limited coverage and low data transmission efficiency in the related art.

[0098] The inventive concept of the present application can be summarized as follows: First, determine the communication coverage range of the uplink control channel according to the reference signal received power and signal-to-noise ratio of the uplink control channel. If it is determined that the communication coverage range of the uplink control channel meets the conditions of medium and far terminals, determine the channel format of the uplink control channel as the long format. Then, determine the data transmission efficiency of the channel scheduling method according to the transmission block size of the uplink shared channel corresponding to the time division scheduling method and the transmission block size of the uplink shared channel corresponding to the frequency division scheduling method. Finally, if it is determined that the data transmission efficiency of the channel scheduling method meets the condition of high-efficiency data transmission, use the channel scheduling method as the target channel scheduling method and schedule the channel using the target channel scheduling method.

[0099] In summary, the embodiments of the present application can select an appropriate channel format according to the communication coverage range of the uplink control channel, improve the coverage range of the uplink control channel, avoid limited coverage of the millimeter-wave system, and reduce the error rate of the uplink shared channel of edge users; and determine the data transmission efficiency of the channel scheduling method according to the transmission block size of the uplink shared channel corresponding to different scheduling methods, so as to select a scheduling method with high data transmission efficiency, which can not only improve the data transmission efficiency in the system, but also effectively improve the system capacity.

[0100] After introducing the main inventive concept of the embodiments of the present application, the following briefly introduces the application scenarios applicable to the technical solutions of the embodiments of the present application. It should be noted that the application scenarios introduced below are only for illustrating the embodiments of the present application rather than limiting them. In specific implementation, the technical solutions provided by the embodiments of the present application can be flexibly applied according to actual needs.

[0101] To facilitate the understanding of the channel control method for the millimeter-wave system provided by the embodiments of the present application, the following further explains this with reference to the accompanying drawings.

[0102] In a possible implementation manner, for a channel control method for a millimeter-wave system provided by the embodiments of the present application, its overall process is as Figure 1 shown and includes the following content:

[0103] In step 101, according to the reference signal received power and signal-to-noise ratio of the uplink control channel, determine the communication coverage range of the uplink control channel.

[0104] In a possible implementation manner, according to the reference signal received power and signal-to-noise ratio of the uplink control channel, determining the communication coverage range of the uplink control channel includes the following three cases:

[0105] Case 1: If the reference signal received power of the uplink control channel is greater than the sum of the preset power threshold and the preset value, and the signal-to-noise ratio of the uplink control channel is greater than the sum of the preset signal-to-noise ratio threshold and the preset value, it is determined that the communication coverage range of the uplink control channel meets the near-end terminal condition.

[0106] For example, if the reference signal received power (Reference Signal Received Power, abbreviated as RSRP) of the uplink control channel > preset power threshold Th1 + preset value Delta, and the signal-to-noise ratio (Signal ToInterference Plus Noise Ratio, abbreviated as SINR) of the uplink control channel > preset signal-to-noise ratio threshold Th2 + preset value Delta, it is determined that the communication coverage range of the uplink control channel meets the near-end terminal condition, that is, the communication coverage is good.

[0107] Case 2: If the reference signal received power of the uplink control channel is less than the preset power threshold, it is determined that the communication coverage range of the uplink control channel meets the mid- and far-end terminal condition.

[0108] For example, if the reference signal received power of the uplink control channel < preset power threshold Th1, it is determined that the communication coverage range of the uplink control channel meets the mid- and far-end terminal condition, that is, the communication coverage is limited.

[0109] Case 3: If the signal-to-noise ratio of the uplink control channel is less than the preset signal-to-noise ratio threshold, it is determined that the communication coverage range of the uplink control channel meets the conditions of the mid- and far-end terminals.

[0110] For example, if the signal-to-noise ratio of the uplink control channel < the preset signal-to-noise ratio threshold Th2, it is determined that the communication coverage range of the uplink control channel meets the conditions of the mid- and far-end terminals, that is, the communication coverage is limited.

[0111] In step 102, if it is determined that the communication coverage range of the uplink control channel meets the conditions of the mid- and far-end terminals, it is determined that the channel format of the uplink control channel is the long format.

[0112] In another possible implementation, if it is determined that the communication coverage range of the uplink control channel meets the conditions of the near-end terminals, it is determined that the channel format of the uplink control channel is the short format.

[0113] For example, as Figure 2 shown, if the communication coverage range of the uplink control channel corresponding to the terminal UE1 meets the conditions of the near-end terminals, it is determined that the channel format of the uplink control channel is the short format; if the communication coverage range of the uplink control channel corresponding to the terminal UE2 meets the conditions of the mid- and far-end terminals, it is determined that the channel format of the uplink control channel is the long format.

[0114] In one possible implementation, after determining that the channel format of the uplink control channel is the long format, the embodiments of the present application will further determine the number of orthogonal frequency division multiplexing symbols used by the long-format uplink control channel according to the communication coverage range of the uplink control channel, specifically including the following three cases:

[0115] Case 1: If the reference signal received power of the uplink control channel is greater than the difference between the preset power threshold and the preset value, and the signal-to-noise ratio of the uplink control channel is greater than the difference between the preset signal-to-noise ratio threshold and the preset value, it is determined that the communication coverage range of the uplink control channel meets the conditions of the midpoint terminals, and the number of orthogonal frequency division multiplexing symbols of the long-format uplink control channel is determined to be N.

[0116] For example, as Figure 3 shown, after determining that the channel format of the uplink control channel corresponding to UE1 is the long format, since the reference signal received power of the uplink control channel > the preset power threshold Th1 - the preset value, and the signal-to-noise ratio of the uplink control channel > the preset signal-to-noise ratio threshold Th2 - the preset value Delta, it is determined that the communication coverage range of the uplink control channel meets the conditions of the midpoint terminals, and the number of orthogonal frequency division multiplexing symbols of the long-format uplink control channel corresponding to UE1 is determined to be N.

[0117] It should be noted that the number of orthogonal frequency division multiplexing symbols N is a value between 2 and 14, excluding 2 and 14, and the farther the terminal is from the base station, the larger the number of orthogonal frequency division multiplexing symbols N.

[0118] Case 2: If the reference signal received power of the uplink control channel is less than the difference between the preset power threshold and the preset value, it is determined that the communication coverage range of the uplink control channel meets the far-end terminal condition, and the number of orthogonal frequency division multiplexing symbols of the long-format uplink control channel is determined to be the preset number of symbols.

[0119] For example, as Figure 3 shown, after determining that the channel format of the uplink control channel corresponding to UE2 is the long format, since the reference signal received power of the uplink control channel < preset power threshold Th1 - preset value Delta, it is determined that the communication coverage range of the uplink control channel meets the far-end terminal condition, and the number of orthogonal frequency division multiplexing symbols of the long-format uplink control channel corresponding to UE2 is determined to be the preset number of symbols. It should be added that the preset number of symbols is usually 14.

[0120] Case 3: If the signal-to-noise ratio of the uplink control channel is less than the difference between the preset signal-to-noise ratio threshold and the preset value, it is determined that the communication coverage range of the uplink control channel meets the far-end terminal condition, and the number of orthogonal frequency division multiplexing symbols of the long-format uplink control channel is determined to be the preset number of symbols.

[0121] For example, as Figure 3 shown, after determining that the channel format of the uplink control channel corresponding to UE3 is the long format, since the signal-to-noise ratio of the uplink control channel < preset signal-to-noise ratio threshold Th2 - preset value Delta, it is determined that the communication coverage range of the uplink control channel meets the far-end terminal condition, and the number of orthogonal frequency division multiplexing symbols of the long-format uplink control channel corresponding to UE3 is determined to be the preset number of symbols.

[0122] The above steps of further distinguishing the number of OFDM symbols used by the uplink control channel when the uplink control channel uses the long format channel fully improve the coverage range of the millimeter wave system and improve the resource utilization rate.

[0123] In step 103, according to the transmission block size of the uplink shared channel corresponding to the time division scheduling method and the transmission block size of the uplink shared channel corresponding to the frequency division scheduling method, the data transmission efficiency of the channel scheduling method is determined.

[0124] In a possible implementation manner, as Figure 4 shown, the embodiments of the present application adopt the following method to determine the transmission block size of the uplink shared channel corresponding to the time division scheduling method, which can be implemented as:

[0125] In step 401, obtain the number of orthogonal frequency division multiplexing symbols that can be allocated to the uplink shared channel corresponding to the time division scheduling method, the number of resource blocks that can be allocated to the uplink shared channel, the number of layers of the uplink shared channel, and the index value of the current modulation and coding strategy.

[0126] In step 402, based on the calculation formula of the transport block size in the 3GPP protocol, determine the transport block size of the uplink shared channel corresponding to the time division scheduling mode.

[0127] For example, the time division scheduling modes of PUCCH and PUSCH are as Figure 5 shown. The uplink shared channel PUSCH and the uplink control channel PUCCH are on different OFDM symbols in a time slot, and the analog beams corresponding to the base station antennas TRx0, TRx1, TRx2, and TRx3 are the optimal analog beams for PUSCH and PUCCH respectively.

[0128] The number of orthogonal frequency division multiplexing symbols available for the uplink shared channel is Symbol n :

[0129] Symbol n = 14 - N

[0130] N represents the number of OFDM symbols occupied by the long format PUCCH;

[0131] The number of resource blocks available for the uplink shared channel is RB i , RB i is the maximum number of resource blocks included in the frequency band;

[0132] The number of layers of the uplink shared channel is Layer n , and the index value of the current modulation and coding strategy (Modulation Coding Scheme, abbreviated as MCS) is MCS n ;

[0133] After determining the above variables, according to the transport block size calculation formula in subsection 5.1.3.2 of 3GPP TS 38.214, the transport block size of the uplink shared channel corresponding to the time division scheduling mode is TBS n_i .

[0134] In a possible implementation manner, as Figure 6 shown, the embodiments of the present application adopt the following method to determine the transport block size of the uplink shared channel corresponding to the frequency division scheduling mode, which can be implemented as:

[0135] In step 601, obtain the number of orthogonal frequency division multiplexing symbols available for the uplink shared channel corresponding to the frequency division scheduling mode, the number of resource blocks available for the uplink shared channel corresponding to the frequency division scheduling mode, the number of layers of the uplink shared channel corresponding to the frequency division scheduling mode, and the index value of the modulation and coding strategy corresponding to the frequency division scheduling mode.

[0136] In step 602, based on the calculation formula of the transport block size in the 3GPP protocol, determine the transport block size of the uplink shared channel corresponding to the frequency division scheduling mode.

[0137] In a possible implementation manner, since selecting analog beams for the fractional channels of PUSCH and PUCCH may cause performance loss in PUSCH reception, the embodiments of the present application need to obtain the index value of the modulation and coding strategy corresponding to the corrected frequency division scheduling manner, and the process is as follows: Figure 7 as shown, including the following contents:

[0138] In step 701, obtain the index value of the modulation and coding strategy corresponding to the time division scheduling manner.

[0139] In step 702, obtain the number of digital channels allocated for the uplink shared channel corresponding to the frequency division scheduling manner and the number of digital channels allocated for the uplink control channel corresponding to the frequency division scheduling manner.

[0140] In step 703, based on the index value of the modulation and coding strategy corresponding to the time division scheduling manner, look up the mapping table between the index value of the modulation and coding strategy and the signal-to-noise ratio to obtain the current signal-to-noise ratio.

[0141] In step 704, obtain the reference signal reception power of the analog beam x allocated for the uplink shared channel and the reference signal reception power of the analog beam y allocated for the long format uplink control channel according to the beam scanning report or the sounding reference signal.

[0142] In step 705, based on the current signal-to-noise ratio, the reference signal reception power of the analog beam x allocated for the uplink shared channel, the reference signal reception power of the analog beam y allocated for the long format uplink control channel, the number of digital channels allocated for the uplink shared channel, and the number of digital channels allocated for the uplink control channel, obtain the updated signal-to-noise ratio.

[0143] In step 706, based on the updated signal-to-noise ratio, look up the mapping table between the index value of the modulation and coding strategy and the signal-to-noise ratio to obtain the index value of the modulation and coding strategy corresponding to the frequency division scheduling manner.

[0144] For example, the frequency division scheduling manner is as follows: Figure 8 as shown, there is an overlap in the time domain between the uplink shared channel PUSCH and the uplink control channel PUCCH. For the base station antennas TRx0 and TRx1, determine the optimal analog beam for PUCCH. For the base station antennas TRx2 and TRx3, determine the optimal analog beam for PUCCH.

[0145] The number of orthogonal frequency division multiplexing symbols available for the uplink shared channel is Symbol m , Symbol m = 14;

[0146] The number of resource blocks available for the uplink shared channel is RB j , RB j= The maximum number of resource blocks included in the frequency band - the number of resource blocks occupied by the long - format uplink shared channel;

[0147] The number of layers of the uplink shared channel is Layer m , and the index value of the modulation and coding strategy corresponding to the time - division scheduling mode is MCS m ;

[0148] The steps for obtaining the index value of the modulation and coding strategy corresponding to the time - division scheduling mode include the following:

[0149] 1. Obtain the index value MCS of the modulation and coding strategy corresponding to the time - division scheduling mode n ;

[0150] 2. Obtain the number of digital channels T allocated to the uplink shared channel corresponding to the frequency - division scheduling mode and the number of digital channels D allocated to the uplink control channel corresponding to the frequency - division scheduling mode;

[0151] 3. Based on the index value of the modulation and coding strategy corresponding to the time - division scheduling mode, look up the mapping table between the index value of the modulation and coding strategy and the signal - to - noise ratio to obtain the current signal - to - noise ratio SINR0;

[0152] 4. Obtain the reference signal received power RSRP of the analog beam x allocated to the uplink shared channel and the reference signal received power RSRP of the analog beam y allocated to the long - format uplink control channel according to the beam scanning report or the sounding reference signal (SRS for short) x and the reference signal received power RSRP of the analog beam y allocated to the long - format uplink control channel y .

[0153] 5. Based on the current signal - to - noise ratio SINR0, the reference signal received power RSRP of the analog beam x allocated to the uplink shared channel x , the reference signal received power RSRP of the analog beam y allocated to the long - format uplink control channel y , the number of digital channels T allocated to the uplink shared channel and the number of digital channels D allocated to the uplink control channel, obtain the updated signal - to - noise ratio SINR m . As shown in the following formula (1):

[0154]

[0155] 6. Based on the updated signal - to - noise ratio SINR m , look up the mapping table between the index value of the modulation and coding strategy and the signal - to - noise ratio to obtain the index value MCS of the modulation and coding strategy corresponding to the frequency - division scheduling mode m ;

[0156] After determining the above variables, according to the transmission block size calculation formula in subsection 5.1.3.2 of 3GPP TS 38.214, the uplink shared channel transmission block size corresponding to the frequency division scheduling mode is TBS m_j .

[0157] In step 104, if it is determined that the data transmission efficiency of the channel scheduling mode meets the high-efficiency data transmission condition, the channel scheduling mode is used as the target channel scheduling mode, and the channel is scheduled using the target channel scheduling mode.

[0158] In a possible implementation manner, if it is determined that the data transmission efficiency of the channel scheduling mode meets the high-efficiency data transmission condition, using the channel scheduling mode as the target channel scheduling mode includes the following two cases:

[0159] If the uplink shared channel transmission block size corresponding to the time division scheduling mode and the uplink shared channel transmission block size corresponding to the frequency division scheduling mode are both greater than the preset buffer data volume, it is determined that both the time division scheduling mode and the frequency division scheduling mode meet the high-efficiency data transmission condition, and the time division scheduling mode is used as the target channel scheduling mode;

[0160] Otherwise, it is determined that the scheduling mode corresponding to the larger transmission block size among the uplink shared channel transmission block size corresponding to the time division scheduling mode and the uplink shared channel transmission block size corresponding to the frequency division scheduling mode meets the high-efficiency data transmission condition, and the scheduling mode corresponding to the larger transmission block size is used as the target channel scheduling mode.

[0161] For example, if the uplink shared channel transmission block size TBS n_i corresponding to the time division scheduling mode and the uplink shared channel transmission block size corresponding to the frequency division scheduling mode is TBS m_j are both greater than the preset buffer data volume Size, the time division scheduling of PUSCH and PUCCH is preferentially selected as the target channel scheduling mode;

[0162] Otherwise, when TBS n_i is greater than TBS m_j , the time division scheduling of PUSCH and PUCCH is preferentially selected as the target channel scheduling mode.

[0163] In summary, the embodiments of the present application can select an appropriate channel format according to the communication coverage range of the uplink control channel, improve the coverage range of the uplink control channel, avoid the coverage limitation of the millimeter wave system, and reduce the bit error rate of the uplink shared channel of edge users; and determine the data transmission efficiency of the channel scheduling mode according to the uplink shared channel transmission block size corresponding to different scheduling modes, so as to select a scheduling mode with high data transmission efficiency, which can not only improve the data transmission efficiency in the system, but also effectively improve the system capacity.
