Description

Bit allocation method for common public radio interface CPRI and related equipment

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a CPRI bit allocation method and related equipment.

Background

Common Public Radio Interface (CPRI) specifications are specifications made by companies working in the industry on the key interfaces within Radio base stations, which define physical layer and data link layer protocols for controlling and managing data transmission between Radio Equipment Controllers (RECs) and Radio Equipment (REs), or between two REs, within a Radio base station.

Referring to the CPRI protocol, a base station is divided into two parts, an REC and an RE (or multiple REs), where each RE has one or more carriers, and when allocating bits for data transmission to a carrier on a certain RE, the REC needs to allocate consecutive bits to the carrier. As shown in fig. 1, CPRI transmits bit data between REC and RE in a time division manner, assuming that 4bit intervals (i.e., C1, C2, C3 and C4) with different bit numbers are already allocated to 4 carriers, there is a gap (also referred to as "chip") between the 4bit intervals, and the bit number contained in the gap is small, so that when a new carrier (e.g., C5) is added and the bit number needs to be allocated to the new carrier, sufficient consecutive bits may not be allocated to the new carrier. However, the total number of remaining bits, i.e. the total number of bits of the gap, is often greater than the number of bits to be allocated, i.e. the total number of remaining bits is sufficient for the carrier to use, which results in a waste of resources.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be understood that the technical solution of the embodiment of the present invention can be applied to wireless communication systems of various systems, for example: a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a Long Term Evolution (LTE) System, a Universal Mobile Telecommunications System (UMTS) or a Wireless Local Area Network (WLAN) communication System, and the like, and the application scenario of the communication System may be an indoor distribution System or an outdoor distribution System.

Specifically, please refer to fig. 2, which is a network architecture diagram according to an embodiment of the present invention. From a specific application point of view, the CPRI specification may be used for data transmission between the REC and the RE of the base station. As shown in fig. 2, the base station is divided into an REC and at least one RE (two are shown in the figure), each RE has one or more carriers, and the REC needs to allocate bits for data transmission, specifically, allocate continuous bit intervals, to each carrier on each RE. The bit interval is determined according to bit number information and position information required by the carrier.

The basic concept of CPRI bit transmission is described below. The data transmission between the REC and the RE is data transmission based on CPRI frames, wherein one CPRI frame period is 10 ms. Each frame is divided into 150 superframes, each superframe being approximately 66.7us (microseconds). Each superframe is divided into 256 basic frames, each of which is about 260ns (nanoseconds) (1chip 1/3.84MHz 260.416667 ns). A CPRI basic frame contains control words and an IQ data part for transmitting IQ data to be transmitted. Specifically, one CPRI basic frame includes 16 slots: w-0.. 15, W-0 is a control slot including a control word, W-1.. 15 is an IQ data slot, and different CPRI rates correspond to different frame structures. For example, as shown in FIG. 3a, when the CPRI rate is 614.4Mbit/s, the structure of the basic frame is shown in FIG. 3 a. Wherein, the gray portion in fig. 3a is the IQ data portion, which is 120 bit; the black part is a control word. For another example, as shown in fig. 3b, when the CPRI rate is 1.25Gbit/s, the basic frame is shown in fig. 3b, and the number of bits of the IQ data portion is 240 bits, and the black portion is the control word. At other CPRI rates, the corresponding IQ bit numbers of the basic frames are different, and are not described herein again.

It should be understood that, in the embodiment of the present invention, the allocation of the number of bits in the CPRI link is the allocation of the number of bits to the IQ part of the CPRI basic frame. That is to say, the CPRI link in the embodiment of the present invention may correspond to the basic frame, the time period of the basic frame is 260ns, and the data of each carrier on each RE is transmitted in the bit interval allocated on each basic frame, that is, each consecutive 260 ns. The bit number distributed by a carrier on a basic frame is directly related to the bandwidth thereof, and the bit distribution rule can be set according to different requirements. For example, a UMTS carrier (5Mhz) may be allocated 24 bits in a basic frame in the downlink direction, an LTE carrier (20Mhz) may be allocated 240 bits in a basic frame in the downlink direction, and so on, and in the presence of data compression, the number of allocated bits may be reduced accordingly.

The embodiment of the invention discloses a CPRI bit allocation method, related equipment and a system, which can realize the allocation of continuous bit intervals for carriers when a CPRI link has no continuous bit intervals. The details are described below.

Referring to fig. 4, it is a schematic structural diagram of a wireless device controller according to an embodiment of the present invention, and specifically, as shown in fig. 4, the wireless device controller according to an embodiment of the present invention includes a determining unit 11, an adjusting unit 12, a message generating unit 13, and a communication unit 14. Wherein the content of the first and second substances,

the determining unit 11 is configured to determine a target number of bits that needs to be allocated to the first carrier.

Wherein the target number of bits is the number of bits required to be allocated for the first carrier for transmitting data. Specifically, the first carrier is a carrier that needs to newly allocate a bit interval with a certain bit number, that is, a target bit number, for data transmission, such as a carrier that is newly added to a certain RE in a communication system including the REC and the RE, or a carrier that is added to a newly added RE due to the newly added RE, and the like, which is not limited in the embodiment of the present invention.

The adjusting unit 12 is configured to adjust a position of a bit interval configured for the second carrier in the common public radio interface CPRI link according to the target bit number determined by the determining unit 11.

The second carrier is a carrier to which a bit interval for data transmission is allocated in the CPRI link, and the bit interval allocated to the second carrier is determined according to bit number information and position information of bits allocated to the second carrier. Further, the adjusted remaining continuous bit number in the CPRI link is not less than the target bit number.

Specifically, the CPRI link according to the embodiment of the present invention may correspond to the IQ data portion of the CPRI basic frame, and allocate bits to each carrier based on the IQ data portion for data transmission. After the determining unit 11 determines the target number of bits, which is the number of bits that need to be allocated to the first carrier, which is a new carrier, the adjusting unit 12 can adjust the position of the bit interval of the carrier to which bits have been allocated.

For example, please refer to fig. 5, which is a schematic structural diagram of a current carrier bit configuration according to an embodiment of the present invention. As shown in fig. 5, it is assumed that the base station is divided into REC, RE0 and RE1 (i.e., two REs), where there are two carriers on RE0, respectively C1 and C3, and there are also two carriers on RE1, respectively C2 and C4. Wherein, assuming that the CPRI link, i.e. the IQ data portion, is divided into 20bit blocks (the bit number of each bit block is determined by the bit number corresponding to the IQ data portion), the bit intervals (i.e. the current configuration) of the 4 carriers in the CPRI link are respectively: c1 corresponds to bit blocks 1-3, i.e. having a bit interval of 1-3, a bit interval of 12-15 for C3, a bit interval of 6-9 for C2, a bit interval of 18-20 for C4, the remaining bits comprising bit blocks 4-5, 10-11 and 16-17. The C1, C2, C3 and C4 may be the second carrier.

The message generating unit 13 is configured to allocate a bit interval corresponding to the target bit number to the first carrier based on the remaining consecutive bits, and generate a control message including the adjusted interval information of the bit interval of the second carrier and the adjusted interval information of the bit interval of the first carrier.

The interval information may include bit number information and position information of the bit interval.

The communication unit 14 is configured to send the control message to a wireless device.

In a specific embodiment, after the adjusting unit 12 performs position adjustment according to the bit interval allocated to each carrier in the current CPRI link, the message generating unit 13 may determine the position information corresponding to the target bit number, determine, for the first carrier, the bit interval corresponding to the target bit number determined by the position information determining unit 11, generate a control message including the interval information of the bit interval of each adjusted carrier (i.e., the first carrier and the second carrier), and send the control message to each RE through the communication unit 14, so that each RE stores the control message, so that the subsequent bit interval can be switched in time to transmit data according to the adjusted bit interval.

Further optionally, in this embodiment of the present invention, the radio equipment controller REC may further include (not shown in the figure):

a detecting unit 15, configured to detect whether a remaining continuous bit number in the CPRI link is smaller than the target bit number, and notify the adjusting unit 12 to adjust a position of a bit interval configured for a second carrier in the CPRI link according to the target bit number when the remaining continuous bit number is detected to be smaller than the target bit number; wherein the remaining continuous bit number is a bit number between every two adjacent bit intervals in the CPRI link.

As a further alternative, in embodiments of the present invention,

the detecting unit 15 is further configured to detect whether the total number of remaining bits in the CPRI link reaches the target bit number, and notify the adjusting unit 12 to adjust the position of a bit interval configured for a second carrier in the CPRI link according to the target bit number when detecting that the total number of remaining bits reaches the target bit number, where the total number of remaining bits is the number of bits in the CPRI link except for the bit interval.

Specifically, after the determining unit 11 determines the target number of bits that is the number of bits that needs to be allocated to the new carrier, that is, the first carrier, the detecting unit 15 may detect whether the total number of remaining bits, that is, the remaining bits in the CPRI link, is sufficient, that is, whether the total number of remaining bits is not less than the target number of bits, and if the total number of remaining bits is not less than the target number of bits, the adjusting unit 12 may adjust the position of the bit interval of the carrier (that is, the second carrier) to which bits have been allocated. Optionally, the detecting unit 15 may further detect whether sufficient consecutive bits remain in the CPRI link, that is, a bit interval not smaller than the target bit number, and if the remaining consecutive bits are insufficient, perform position adjustment on the bit interval of the carrier to which the bits have been allocated through the adjusting unit 12. Further optionally, the detecting unit 15 may further detect whether the total number of remaining bits in the CPRI link reaches the target bit number when detecting that the remaining continuous bit number in the CPRI link is smaller than the target bit number, so as to adjust the position of the bit interval of the carrier with the allocated bits through the adjusting unit 12 when the target bit number is reached, that is, when the target bit number is not smaller than the target bit number.

Further, please refer to fig. 6 in conjunction with fig. 5, and fig. 6 is a schematic diagram of a sending control message according to an embodiment of the present invention. As shown in fig. 6, when carrier C5 is newly added to RE1, continuous bits for data transmission need to be allocated to new carrier C5, and the target number of bits needed to be allocated to C5 is assumed to be 4bit blocks. At this time, the adjusting unit 12 adjusts the positions of the bit sections configured for the second carrier, i.e., the positions of C1, C3, C2, and C4, to the 4bit blocks allocated for C5 as needed, so as to ensure that the bit sections of consecutive 4bit blocks are allocated for C5. For example, the bit interval corresponding to C1 adjusted (pre-configured) by the adjusting unit 12 is bit block 1-3 (unchanged), the bit interval of C3 is 8-11, the bit interval of C2 is 4-7, and the bit interval of C4 is 12-14. And allocates a bit interval including 4bit blocks of bit blocks 15 to 18 to the new carrier C5, the message generating unit 13 can generate a control message including interval information of the bit interval of each carrier, and transmit the control message to each RE through the communication unit 14. And after receiving the control message comprising the interval information of the bit interval corresponding to the carrier wave, the RE stores the interval information and returns a confirmation message to the REC.

Optionally, the wireless device may include a plurality; the message generating unit 13 is specifically configured to:

determining wireless devices to which the first carrier and the second carrier belong, and generating a control message corresponding to each wireless device; the control message corresponding to each wireless device includes interval information of a bit interval of the carrier.

Further, the specific way for the communication unit 14 to send the control message to the wireless device is as follows:

That is, the message generating unit 13 may generate control messages corresponding to different REs according to carriers to which the different REs belong, and send the control messages to the corresponding REs through the communication unit 14. For example, as shown in fig. 6, the message generating unit 13 may generate two control messages, i.e., a control message corresponding to RE0 and a control message corresponding to RE1, according to RE0 and RE 1. The control message corresponding to the RE0 includes the interval information of the bit intervals of the adjusted carriers C1 and C3, and the control message corresponding to the RE1 includes the interval information of the bit intervals of the adjusted carriers C2 and C4 and the newly added C5. So that the control messages can be transmitted to the corresponding REs through the communication unit 14, respectively. RE0 and RE1 store the adjusted interval information after receiving the respective control messages, and return acknowledgement messages to the REC, respectively.

The communication unit 14 is further configured to notify the wireless device of data transmission based on the bit interval in the control message through a switching instruction encapsulated in a preset bit position in a CPRI frame where the CPRI link is located.

Optionally, in this embodiment of the present invention, the specific way for the communication unit 14 to notify the wireless device of data transmission based on the bit interval in the control message through the switching instruction encapsulated in the preset bit position in the CPRI frame where the CPRI link is located may be:

Optionally, in this embodiment of the present invention, the specific way for the communication unit 14 to notify the wireless device of data transmission based on the bit interval in the control message through the switching instruction encapsulated in the preset bit position in the CPRI frame where the CPRI link is located may also be:

That is, after the REC sends the control message to each RE through the communication unit 14, specifically, when receiving an acknowledgement message returned by the RE to acknowledge the receipt of the control message, the communication unit 14 may further notify each RE through a control word in the CPRI frame, even a data bit, that is, an IQ data part, to receive/send data according to a bit interval in the previously received control message, that is, trigger the preconfiguration to take effect.

It should be noted that the control message cannot be used to notify each RE to transmit data according to the bit interval in the control message, because the control message does not have precise time and cannot control the switching time of the CPRI bit interval. The control word or data bit and the CPRI time slot have definite corresponding relation, which is suitable for switching CPRI bit interval.

For example, please refer to fig. 7 in combination with fig. 5 and fig. 6, and fig. 7 is a schematic diagram illustrating a switching between bit intervals according to an embodiment of the present invention. As shown in fig. 7, assuming that the switching instruction is encapsulated in a preset control word (referred to as "switching control word" in the figure) of the CPRI frame, the communication unit 14 can notify the RE0 and the RE1 of the bit interval switching through the control word. Upon receiving the control word, RE0 and RE1 may switch the bit interval corresponding to the carrier from the current bit interval (current configuration) to the bit interval (pre-configuration) indicated by the received control message, so as to transmit data based on the bit interval in the control message. After the switching is successful, the RE can inform the REC of the switching success message. Therefore, when the CPRI link has no continuous bit interval, the continuous bit interval can be distributed to the carrier, and the resource waste is avoided.

Referring to fig. 8, a schematic structural diagram of a wireless device according to an embodiment of the present invention is shown, and specifically, as shown in fig. 8, the wireless device according to the embodiment of the present invention includes a communication unit 21 and a switching unit 22. Wherein the content of the first and second substances,

the communication unit 21 is configured to receive a control message that includes interval information of a bit interval of a corresponding carrier and is sent by a radio device controller, and store the interval information, where the interval information includes bit number information and position information of the bit interval.

In a specific embodiment, when a carrier is newly added to a certain RE in a communication system formed by an REC and an RE, or a carrier added to the newly added RE due to the newly added RE needs to allocate continuous bits with a certain bit number, that is, a target bit number, to the newly added carrier (a first carrier), the REC may adjust, according to the target bit number, a position of a bit interval corresponding to a second carrier to which bits have been allocated in a CPRI link, allocate a bit interval corresponding to the target bit number to the first carrier, and generate a control message including adjusted interval information of the bit interval of the second carrier and interval information of the bit interval of the first carrier. Wherein the interval information includes bit number information and position information of the bit interval.

After receiving the control message sent by the REC through the communication unit 21, the RE may store the interval information of the bit interval preconfigured (i.e., adjusted) for the carrier on the RE included in the control message, so as to switch the bit interval according to the control message in time in the following, and transmit data according to the preconfigured bit interval. In addition, the RE may also return an acknowledgement message for acknowledging receipt of the control message to the REC through the communication unit 21, so that the REC initiates a bit interval switching indication based on the control message.

The communication unit 21 is further configured to receive a switching instruction encapsulated in a preset bit position in a CPRI frame where the common public radio interface CPRI link is located.

Optionally, the preset position is a control word in a CPRI frame where the CPRI link is located or a data bit in the CPRI frame where the CPRI link is located.

The switching unit 22 is configured to switch, in response to the switching instruction, the bit interval corresponding to the carrier to the bit interval in the control message, so as to transmit data based on the bit interval in the control message.

Further, in the embodiment of the present invention,

the communication unit 21 is further configured to switch the bit interval corresponding to the carrier to the bit interval in the control message in response to the switching instruction, so as to transmit data through the current bit interval corresponding to the carrier in the CPRI link before transmitting data based on the bit interval in the control message.

Wherein the current bit interval (current configuration) is a bit interval configured for the carrier by the radio equipment controller before the control message is received. That is, the switching unit 22 still transmits data in the original bit interval (i.e., the current bit interval described above) before switching the bit interval according to the control information to transmit data based on the adjusted bit interval. Therefore, seamless switching is realized based on the preset position, such as a switching instruction corresponding to the control word, so that the system capacity is increased, and the CPRI data transmission efficiency is improved to a certain extent.

Specifically, when receiving a switching instruction corresponding to a preset position in the CPRI frame, such as a control word, the communication unit 21 may perform real-time processing through the switching unit 22, and switch each carrier on the RE from the original bit interval (i.e., the current bit interval) to the bit interval preconfigured in the control message for data transmission, thereby implementing lossless (micro-loss) switching. Specifically, as shown in fig. 7, it is assumed that the REC encapsulates the switching command in a preset control word (referred to as "switching control word" in the figure) of the CPRI frame, and notifies RE0 and RE1 of the bit interval switching through the control word. When the communication unit 21 receives the control word, the switching unit 22 may switch the bit interval corresponding to the carrier from the current bit interval (current configuration) to the bit interval (pre-configuration) indicated by the received control message, so as to transmit data based on the bit interval in the control message.

Optionally, the switching unit 22 may use a control word (or a data bit) to perform bit interval switching in various ways, for example, the CPU is notified by an interrupt to perform switching, or the switching is performed directly by logic or a chip, and the embodiment of the present invention is not limited. Further, after the handover is completed, the RE may notify the REC of the handover success message through the communication unit 21, that is, the REC is informed to take effect based on the pre-configuration of the bit interval in the control message.

Please refer to fig. 9, which is a flowchart illustrating a CPRI bit allocation method according to an embodiment of the present invention, specifically, the method according to the embodiment of the present invention may be specifically applied to the REC, and as shown in fig. 9, the CPRI bit allocation method includes:

The bit number corresponding to the bit interval to be allocated is the target bit number.

102. And adjusting the position of a bit interval configured for the second carrier in the CPRI link according to the target bit number.

The second carrier is a carrier to which a bit interval for data transmission has been allocated in the CPRI link, and the bit interval corresponding to the second carrier is determined according to bit number information and position information of bits allocated to the second carrier. Further, the adjusted remaining continuous bit number in the CPRI link is not less than the target bit number.

Further, before adjusting the position of the bit interval configured for the second carrier in the CPRI link according to the target bit number, the REC may detect whether a remaining continuous bit number in the CPRI link is smaller than the target bit number, where the remaining continuous bit number is a bit number between every two adjacent bit intervals in the CPRI link; and if the residual continuous bit number is smaller than the target bit number, executing the step of adjusting the position of a bit interval configured for the second carrier in the CPRI link according to the target bit number.

Further, the REC may also detect whether a total number of remaining bits in the CPRI link reaches the target number of bits, where the total number of remaining bits is the number of bits in the CPRI link except for the bit interval; and if the total number of the residual bits reaches the target bit number, executing the step of adjusting the position of a bit interval configured for a second carrier in the CPRI link according to the target bit number. For example, when the remaining continuous bit number is smaller than the target bit number, triggering to further detect whether the total number of remaining bits in the CPRI link reaches the target bit number, so as to adjust the position of the bit interval of the carrier (i.e., the second carrier) to which bits have been allocated when the target bit number is reached, that is, when the target bit number is not smaller than the target bit number.

Specifically, after determining the target bit number, which is the number of bits that needs to be allocated to the new carrier, that is, the first carrier, the REC may detect whether sufficient consecutive bits, that is, a bit interval not smaller than the target bit number, remain in the CPRI link, and if the remaining consecutive bits are insufficient, step 102 may be executed to perform position adjustment on the bit interval of the carrier to which the bits have been allocated. Optionally, it may also be detected whether all remaining bits in the CPRI link, that is, the total number of remaining bits, is sufficient, that is, whether the total number of remaining bits is not smaller than the target number of bits, and if the total number of remaining bits is not smaller than the target number of bits, step 102 may be executed to perform position adjustment of the bit interval of the carrier with the allocated bits.

103. Allocating a bit interval corresponding to the target bit number to the first carrier based on the remaining consecutive bits, and generating a control message including the adjusted interval information of the bit interval of the second carrier and the adjusted interval information of the bit interval of the first carrier.

104. Transmitting the control message to a wireless device.

In a specific embodiment, after determining the location information corresponding to the target bit number according to the bit interval allocated to each carrier in the current CPRI link, the REC may determine the bit interval corresponding to the first carrier, generate a control message including the interval information of the bit interval of each adjusted carrier (i.e., the first carrier and the second carrier), and send the control message to each RE, so that each RE stores the control message, and then performs subsequent bit interval switching in time to transmit data according to the adjusted bit interval.

Optionally, the wireless device RE may include a plurality of RE; the generating the control message including the adjusted interval information of the bit interval of the second carrier and the adjusted interval information of the bit interval of the first carrier may specifically be: determining wireless devices to which the first carrier and the second carrier belong, and generating a control message corresponding to each wireless device; the control message corresponding to each wireless device includes interval information of a bit interval of the carrier. Further, the sending the control message to the wireless device may specifically be: and respectively sending the control message corresponding to the wireless device to each wireless device.

That is to say, the REC may generate control messages corresponding to different REs according to carriers to which the different REs belong, and send each control message to the corresponding RE.

105. And informing the wireless equipment of transmitting data based on the bit interval in the control message through a switching instruction encapsulated in a preset bit position in a CPRI frame where the CPRI link is located.

The notifying, by the switching instruction encapsulated in the preset bit position in the CPRI frame where the CPRI link is located, of the wireless device to transmit data based on the bit interval in the control message may specifically be: encapsulating a preset switching instruction in a control word in a CPRI frame where the CPRI link is located, and informing the wireless equipment of transmitting data according to a bit interval in the control message through the control word; or, encapsulating a preset switching instruction in a data bit in a CPRI frame where the CPRI link is located, and notifying the wireless device of transmitting data according to a bit interval in the control message through the data bit. That is, after the REC sends the control message to each RE, specifically, when receiving an acknowledgement message returned by the RE to acknowledge receipt of the control message, the REC may notify each RE through a control word in the CPRI frame, even a data bit, that is, an IQ data part, to receive/send data according to a bit interval in the previously received control message, that is, trigger the preconfiguration to take effect.

It should be noted that, before switching the bit interval according to the control information to transmit data based on the adjusted bit interval, the RE still transmits data according to the original bit interval (i.e., the current bit interval). Therefore, seamless switching is realized based on the preset position, such as a switching instruction corresponding to the control word, so that the system capacity is increased, and the CPRI data transmission efficiency is improved to a certain extent.
