Description

Information processing method, base station, terminal and system

Technical Field

The present invention relates to Orthogonal Frequency Division Multiplexing (OFDM) technology in the field of communications, and in particular, to an information processing method, a base station, a terminal, and a system.

Background

In a wireless communication system based on the OFDM technology, a Reference demodulation pilot is a pattern of a Reference pilot predefined by a protocol, for example, multiple transmission modes are specified in release 8 of Long Term Evolution (LTE), such as transmission mode 1 (single antenna transmission mode), transmission mode 2 (diversity transmission mode), transmission mode 3 (open-loop spatial multiplexing mode), transmission mode 4 (closed-loop spatial multiplexing mode), transmission mode 5 (single-layer closed-loop precoding mode), transmission mode 6 (multi-user spatial multiplexing mode), etc., which are all Reference demodulation based on a Cell specific Reference Resource (CRS), and such demodulation pilot is common to cells and the pattern is relatively fixed. In different subframe types, the pattern can be changed, but the pattern can not be changed with different users and can not be changed with the change of application scenes.

In the later 8 th edition, the function of CRS is split, one part is CSI-rs (channel state information Reference resource) for channel measurement, and the other part is Demodulation Reference signal (DMRS) pilot (proprietary Demodulation Reference pilot) for data Demodulation; the DMRS pilot is generally carried by different Resource Elements (REs) from data, and is multiplexed in a Resource Block (RB) by a time-frequency division manner; in current LTE, a channel and reference signal map is shown in fig. 1 below in one RB of a basic time interval (subframe) frequency domain and in a common Content Provider (CP) common subframe. Other subframes, such as Time Division Duplex (TDD) special subframes, extended CP subframes, etc., may refer to 3rd Generation Partnership Project (3 rd Generation Partnership Project, 3 GPP) specification TS 36.211 for channel and reference signal mapping. For downlink transmission, the resource blocks are defined as shown in fig. 2.

The DMRS pattern has some enhancement in flexibility with respect to CRS, and for layer 1 or layer 2 case it uses port 7 and/or port 8, corresponding to 12 REs, and when > layer 2, all 24 REs are used for pilot transmission. Compared with the prior reference demodulation pilot frequency, the method has the advantages that the pilot frequency can be configured by UE specific, flexible self-adaptation can be carried out according to the layer number, and the pilot frequency overhead is effectively saved under the condition of less layer number.

However, in the aforementioned systems, the pilot design still has several major problems:

the position of the pilot frequency is transmitted in the same OFDM symbol as the downlink control or downlink data in the time domain, demodulation cannot be started immediately when the RE of the control or data is received, and the need to perform pilot frequency estimation first affects the processing speed of the terminal.

Detailed Description

Example one

An embodiment of the present invention provides an information processing method, which is applied to a base station, as shown in fig. 3,

in a basic physical layer time interval of a channel containing reference pilots and transmission information, when the transmission information is data and the transmission channel is a data channel, the first type of reference demodulation pilots include first type of data reference demodulation pilots, and the second type of reference demodulation pilots include second type of data reference demodulation pilots, the method may include:

step 101, determining first parameter information of a first-type reference demodulation pilot frequency.

In a basic physical layer time interval (e.g., a subframe) that includes data reference pilots and data channels, the base station needs to send at least the data reference pilots and the data channels. Different names may be used for the base physical layer time intervals of different systems. Preferably, the base station transmits the first type of data channel reference demodulation pilot at the earlier position. Generally, we use the first kind of control reference demodulation pilot as a basic reference demodulation pilot, and the first column of data demodulation pilots exists for different situations, such as different sub-frame lengths, different frame structures, different moving speeds, different port numbers, and different transmission modes. Since such pilots are mostly used, the base station determines first parameter information, such as transmission position, sequence, power, density, etc., of the first type data reference demodulation pilots before the data channel is transmitted, and then transmits the first type data reference demodulation pilots according to the first parameter information as shown in fig. 4.

And 102, sending the first type reference demodulation pilot frequency to the terminal according to the first parameter information.

The first type of data reference demodulation pilot frequency is positioned in front of the initial symbol of the downlink data channel; the first type of data reference demodulation pilot is associated with a data channel. The first type of data reference demodulation pilot is associated with a data channel transmitted in a base physical layer time interval. Here, association is to indicate that the first type of data reference demodulation pilot is transmitted using the same transmission technique or a related transmission technique for one or more layers of data. For example, one or more layers of demodulated pilot and data use the same precoding, which may not be signaled to the terminal, which together with the physical channel constitutes one logical channel, but the logical channels over which the data and pilot travel are the same. A further correlation is that the transmission channel over which the data travels and the transmission channel over which the pilot travels have a linear transformation relationship, e.g., a transformation is performed on the channel over which the data travels and the channel over which the pilot travels by a linear transformation matrix W, whose dimension is related to the number of pilot ports and the number of transmission layers. In general, in the latter manner, W is required to be agreed upon or interacted between the base station and the terminal.

And 103, determining the sending state information and/or the second parameter information of the second-type reference demodulation pilot frequency.

Preferably, the transmission status information of the second type data reference demodulation pilot indicates: the second type of data reference demodulation pilot is present or absent.

Further, the method further comprises: and determining the second parameter information according to preset information.

In addition to transmitting the first type of data reference demodulation pilots, the base station needs to consider whether the second type of data reference demodulation pilots for data demodulation need to be transmitted. Here, the second type of data reference demodulation pilot can be regarded as an enhanced reference demodulation pilot. There are two cases for the transmission of the enhanced reference demodulation pilot:

one is to determine whether to send a second type of data reference demodulation pilot.

One is that it has been predetermined that a second type of data reference demodulation pilot needs to be sent, but its parameters need to be further determined.

For the first case, the base station needs to determine whether the second-type data reference demodulation pilot needs to be sent, and the determination may be determined by the base station according to a specific situation, that is, the second parameter information is determined according to the preset information, such as:

length of physical time interval: if the base station considers that a basic time interval length is very long, the second type data reference demodulation pilot frequency can be sent;

time domain length of data channel: this situation generally occurs when a control channel is separated between the first-type data reference demodulation pilot and the second-type data reference demodulation pilot, and if the length of the control channel is considered to be greater than a preset length, the second-type reference demodulation pilot is considered to be sent;

number of subcarriers: if the number of the sub-carriers of the first type of data reference demodulation pilot frequency is less than that of the sub-carriers of the data channel, the second type of reference demodulation pilot frequency can be sent;

subcarrier spacing: if the number of the sub-carriers of the first type of data reference demodulation pilot frequency is larger than the sub-carrier interval of the data channel, the second type of reference demodulation pilot frequency can be sent;

traffic type of data: if the data service type has high requirement on reliability, the second type of reference demodulation pilot frequency can be sent;

subsystem type: if the type of the subsystem has high requirement on reliability, the second type of reference demodulation pilot frequency can be sent;

working frequency point of the subsystem: if the working frequency point is high frequency, the second type of reference demodulation pilot frequency can be sent;

transmission mode and/or technique: if the transmission mode or technology is multi-layer pre-coding transmission, the second type of reference demodulation pilot frequency can be sent;

number of ports demodulated: if more demodulated ports need to be sent, the second type of reference demodulation pilot frequency can be sent;

type of demodulation pilot: if the first type of reference pilot frequency is a pre-coding pilot frequency, the second type of reference demodulation pilot frequency of different ports can be sent; or the first type of reference pilot is a non-precoded pilot, the density of the second type of reference demodulation pilot of the same port can be increased.

In this case, the base station may further send the indication information of the second type data reference demodulation pilot to indicate whether the second type data reference demodulation pilot exists; in this way, the terminal can determine whether the second type of data reference demodulation pilot exists for data demodulation according to the indication information.

The base station may also determine whether the second type data reference demodulation pilot exists not by signaling, but by the same rule as the terminal, and the terminal determines whether the second type data reference demodulation pilot is sent by the same rule as the base station, and may agree on such a rule according to at least one of the length of the above-mentioned physical time interval, the time domain length and/or the number of subcarriers and/or the subcarrier interval of the data channel, the type of data to be transmitted, the type of subsystem, the baseband modulation waveform used by the second type data reference demodulation pilot and/or the data channel, the operating frequency point of the subsystem, the transmission mode and/or technology, the number of ports to be demodulated, and the type of the second type data reference demodulation pilot.

And 104, sending the second type reference demodulation pilot frequency or not sending the second type reference demodulation pilot frequency according to the sending state information and/or the second parameter information.

Wherein the first type of data reference demodulation pilot is located at a position before the second type of data reference demodulation pilot.

Therefore, the first type of reference demodulation pilot frequency is always positioned before the transmission information and can be used as a basic demodulation pilot frequency, the second type of demodulation pilot frequency can determine whether the first type of reference demodulation pilot frequency exists or not according to needs, and different processing is carried out on different services, so that the pilot frequency is effectively sent according to some characteristics of a terminal, the services and a subsystem, and the utilization rate and the processing speed of the pilot frequency are effectively improved.

For the transmission of the second type data reference demodulation pilot, the second parameter information corresponding to the second type data reference demodulation pilot, including but not limited to at least one of pilot pattern, sequence, density, power, port parameter, time domain position, frequency domain position, number of REs, multiplexing mode, orthogonal code length, etc., may be flexibly determined according to some factors, which have an influence on the second parameter information of the second type data reference demodulation pilot, including but not limited to the length of physical time interval, the time domain length and/or the number of subcarriers and/or the interval of subcarriers of the data channel, the type of data to be transmitted, the type of subsystem, the baseband modulation waveform used by the second type data reference demodulation pilot and/or the data channel, the operating frequency point of the subsystem, the transmission mode and/or technology, the number of demodulated ports, and at least one of the types of the second type data reference demodulation pilot. The base station may further send indication information of second parameter information of the second type data reference demodulation pilot, which may also be used by the terminal to determine the second type data reference demodulation pilot. Or the base station may determine the second parameter information of the second type data reference demodulation pilot according to the same rule as the terminal, for example, such a rule may be determined according to one or more of the aforementioned "length of physical time interval, time domain length of data channel and/or number of subcarriers and/or subcarrier interval, type of data transmitted, subsystem type, baseband modulation waveform used by the second type data reference demodulation pilot and/or the data channel, operating frequency point of subsystem, transmission mode and/or technology, number of ports for demodulation, and type of demodulating the second type data reference demodulation pilot".

Further, the sequence parameters and/or power parameters of the first type data reference demodulation pilot frequency and the second type data reference demodulation pilot frequency are configured independently.

Here, the sequence parameters and/or power parameters for the first type data reference demodulation pilots and the second type data reference demodulation pilots are configured in different manners, for example, the sequence parameters and/or power parameters for the first type data reference demodulation pilots are configured through high layer signaling, and the sequence parameters and/or power parameters for the second type data reference demodulation pilots are configured through control signaling in the physical control channel.

Further, the first type data reference demodulation pilot frequency is positioned in front of the control information sending position of the transmission information transmission.

Further, the second type data reference demodulation pilot frequency is positioned after the transmitted control information sending position.

Further, the sending position of the second type data reference demodulation pilot frequency does not exceed the starting position of the data channel.

Further, the second type data reference demodulation pilot is located after the data channel.

Further, the transmission state information of the second type data reference demodulation pilot is notified through a control channel.

For example, the transmission position of the first type of data reference demodulation pilot is relatively fixed and is on a different time domain symbol from the data channel, but the transmission position of the second type of data reference demodulation pilot is much more flexible, and the parameters, such as pattern, density, position, power, etc., of the second type of data reference demodulation pilot have more flexibility, and the multiplexing mode with the data channel is also various, and the three multiplexing modes are shown in fig. 5. If it is considered that the control channel is also transmitted in the physical time interval, since the second parameter information of the second type data reference demodulation pilot can be notified by the base station through the physical control channel in this case, the multiplexing manner is as shown in fig. 6.

Further, the first type data reference demodulation pilot and the second type data reference demodulation pilot may have different uses, for example, the first type data reference demodulation pilot is used for demodulation of one data block, and the second type data reference demodulation pilot is used for demodulation of other data blocks, as shown in fig. 7-a; or the first type of data reference demodulation pilot is used for demodulation of one layer group or port group (namely demodulation of a preset part layer), and the second type of data reference demodulation pilot is used for demodulation of other layer groups or port groups (namely demodulation of other layers except the preset part layer); here layer combination port group is the corresponding concept, as shown in fig. 7-b; or the first type of data reference demodulation pilot belongs to the first pilot port group set, the second type of data reference demodulation pilot belongs to the second pilot port set, and the first pilot port set is a subset of the second pilot port set, as shown in fig. 7-c.

It should be noted that the sequence parameters and/or power parameters of the first type data reference demodulation pilot and the second type data reference demodulation pilot are configured in different manners, for example, the sequence parameters and/or power parameters of the first type data reference demodulation pilot are configured by high-level signaling, and the sequence parameters and/or power parameters of the second type data reference demodulation pilot are configured by control signaling in the physical control channel.

In a basic physical layer time interval of a channel comprising reference pilots and transmission information, when the transmission information is control information and the transmission channel is a control channel, the first type of reference demodulation pilots comprises first type of control reference demodulation pilots, and the second type of reference demodulation pilots comprises second type of control reference demodulation pilots, the method may comprise:

In a basic physical layer time interval (e.g., a subframe) including control reference pilots and control channels, a base station needs to send at least the control reference pilots and the control channels. The base physical layer time intervals for different subsystems may use different names. Preferably, the base station transmits the first type of control channel reference demodulation pilot at the earlier position. Generally, we use the first kind of control reference demodulation pilot as a basic reference demodulation pilot, and the first column of control demodulation pilots exists for different situations, such as different sub-frame lengths, different frame structures, different moving speeds, different port numbers, and different transmission modes. Since such pilots are mostly used, the base station determines first parameter information, such as a transmission position, a transmission sequence, a transmission power, a transmission density, and the like, of the first type of control reference demodulation pilot before the control channel is transmitted, and then transmits the first type of control reference demodulation pilot according to the first parameter information.

The first kind of control reference demodulation pilot frequency is associated with a control information channel transmitted in a time interval of a basic physical layer; here, association is to indicate that one or more layers of the first type of control reference demodulation pilot are transmitted using the same transmission technique or a related transmission technique using the control information. For example, one or more layers of demodulation pilots and control information use the same precoding, which may not be signaled to the terminal, which together with the physical channel constitutes one logical channel, but the logical channels over which the control information and pilots travel are the same. A further correlation is that the channel over which the control information travels and the channel over which the pilot travels have a linear transformation relationship, e.g., a transformation is performed on the channel over which the control information travels and the channel over which the pilot travels by a linear transformation matrix W, whose dimension is related to the number of pilot ports and the transmission control information. In general, in the latter manner, W is required to be agreed upon or interacted between the base station and the terminal.

Preferably, the transmission status information of the second type control reference demodulation pilot indicates: there is a second type of control reference demodulation pilot or there is no second type of control reference demodulation pilot.

For the transmission of the second type of control reference demodulation pilot, parameters corresponding to the second type of control reference demodulation pilot, including but not limited to pilot pattern, sequence, density, power, port parameters, time domain position, frequency domain position, RE number, multiplexing mode, orthogonal code length, etc., may be flexibly determined according to factors that have an influence on the parameters of the second type of control reference demodulation pilot, including but not limited to the length of physical time interval, the time domain length and/or subcarrier number and/or subcarrier interval of the control channel, the type of control information to be transmitted, the type of subsystem, the baseband modulation waveform used by the second type of control reference demodulation pilot and/or the control channel, the operating frequency point of the subsystem, the transmission mode and/or technology, the number of ports to be demodulated, demodulating at least one of the type (precoded or non-precoded) of the second type of control reference demodulation pilot.

The base station may further send information indicative of second parameter information of the second type of control reference demodulation pilot, which may be used by the terminal to determine the second type of control reference demodulation pilot. Or the base station may determine the second parameter information of the second type of control reference demodulation pilot according to the same rule as the terminal, for example, such a rule may be agreed according to one or more of the aforementioned "length of physical time interval, time domain length and/or number of subcarriers and/or subcarrier interval of the control channel, type of control information transmitted, subsystem type, baseband modulation waveform used by the second type of control reference demodulation pilot and/or the control channel, operating frequency point of subsystem, transmission mode and/or technology, number of ports for demodulation, and type (precoding or non-precoding) for demodulating the second type of control reference demodulation pilot.

In addition to transmitting the first type of control reference demodulation pilot, the base station needs to consider whether the second type of control reference demodulation pilot needs to be transmitted for control demodulation. Here, the second type of control reference demodulation pilot can be regarded as an enhanced reference demodulation pilot. The second category of control reference demodulation pilot transmission has two cases:

one is to determine whether to send a second type of control reference demodulation pilot.

One is that it has been predetermined that a second type of control reference demodulation pilot needs to be sent, but its parameters need to be further determined.

For the first case, the base station needs to determine whether the second-type control reference demodulation pilot needs to be sent, and the determination may be determined by the base station according to a specific situation, that is, the second parameter information is determined according to the preset information, such as:

length of physical time interval: if the base station considers that a basic time interval length is very long, the second type of reference demodulation pilot frequency can be sent;

time domain length of control channel: this situation generally occurs when a control channel is separated between the first-type control reference demodulation pilot and the second-type control reference demodulation pilot, and if the length of the control channel is considered to be greater than a preset length, the second-type control demodulation pilot is considered to be sent;

number of subcarriers: if the number of the sub-carriers of the first type of control reference demodulation pilot frequency is less than that of the sub-carriers of the control channel, the second type of reference demodulation pilot frequency can be sent;

subcarrier spacing: if the number of the sub-carriers of the first type of control reference demodulation pilot frequency is larger than the sub-carrier interval of the control channel, the second type of reference demodulation pilot frequency can be sent;

the type of traffic controlled: if the control service type has high requirement on reliability, the second type of reference demodulation pilot frequency can be sent;

In this case, the base station may further send the indication information of the second type control reference demodulation pilot to indicate whether the second type control reference demodulation pilot exists; in this way, the terminal can determine whether the second type of control reference demodulation pilot exists for control demodulation according to the indication information.

The base station may also determine whether the second type of control reference demodulation pilot exists not by signaling, but by using the same rule as the terminal to determine whether the second type of control reference demodulation pilot is sent or not by using the same rule as the base station, and the terminal may determine whether the second type of control reference demodulation pilot exists or not by using the same rule as the terminal, where the rule is determined by using one or more of the length of the above-mentioned physical time interval, the time domain length and/or the number of subcarriers and/or the subcarrier interval of the control channel, the type of control information to be transmitted, the type of subsystem, the baseband modulation waveform used by the second type of control reference demodulation pilot and/or the control channel, the operating frequency point of the subsystem, the transmission mode and/or technology, the number of ports to be demodulated, and the type of the second type of control reference demodulation pilot.

For the transmission of the second type of control reference demodulation pilot, the second parameter information corresponding to the second type of control reference demodulation pilot, including but not limited to at least one of pilot pattern, sequence, density, power, port parameter, time domain position, frequency domain position, number of REs, multiplexing mode, orthogonal code length, etc., may be flexibly determined according to some factors that have an influence on the second parameter information of the second type of control reference demodulation pilot, including but not limited to the length of physical time interval, the time domain length and/or the number of subcarriers and/or the subcarrier interval of the control channel, the type of control information to be transmitted, the subsystem type, the baseband modulation waveform used by the second type of control reference demodulation pilot and/or the control channel, the operating frequency point of the subsystem, the transmission mode and/or technology, the number of demodulated ports, and at least one of the types (pre-coded, non-pre-coded) of the second type of control reference demodulation pilot. The base station may further send indication information of second parameter information of the second type control reference demodulation pilot, which may also be used by the terminal to determine the second type control reference demodulation pilot. Or the base station may determine the second parameter information of the second type of control reference demodulation pilot according to the same rule as the terminal, for example, such a rule may be determined according to one or more of the above-mentioned "length of physical time interval, time domain length and/or number of subcarriers and/or subcarrier interval of the control channel, type of control information transmitted, subsystem type, baseband modulation waveform used by the second type of control reference demodulation pilot and/or the control channel, operating frequency point of subsystem, transmission mode and/or technology, number of ports for demodulation, and type of demodulation of the second type of control reference demodulation pilot". The terminal can acquire the second type control reference demodulation pilot frequency parameter in the current sub-frame based on the appointed rule and correctly receive the reference pilot frequency and carry out channel estimation.

Further, the sequence parameters and/or power parameters of the first type of control reference demodulation pilot and the second type of control reference demodulation pilot are configured independently.

Further, the first type of control reference demodulation pilot is used for demodulation of one information block, and the second type of control reference demodulation pilot is used for demodulation of other information blocks.

Further, the first type of control reference demodulation pilot is located before the transmission position of the transmitted control information.

Further, the transmission state information of the second type control reference demodulation pilot indicates: there is a second type of control reference demodulation pilot or there is no second type of control reference demodulation pilot.

For example, the transmission position of the first type of control reference demodulation pilot is relatively fixed and is on a different time domain symbol from the control channel, but the transmission position of the second type of control reference demodulation pilot is much more flexible, and the second parameter information, such as pattern, density, position, power, etc., of the second type of control reference demodulation pilot has more flexibility, and the multiplexing manner with the control channel is also various as shown in fig. 9. The sequence parameters and/or power parameters of the first type of control reference demodulation pilot frequency and the second type of control reference demodulation pilot frequency are configured in different modes, for example, the sequence parameters and/or power parameters of the first type of control reference demodulation pilot frequency are configured through one set of high-level signaling, and the sequence parameters and/or power parameters of the second type of control reference demodulation pilot frequency are configured through another set of high-level signaling.

The first type of control reference demodulation pilot signal and the second type of control reference demodulation pilot signal may have different uses. For example, a first type of control reference demodulation pilot is used for demodulation of one control signaling group, and a second type of control reference demodulation pilot is used for demodulation of other control signaling groups, as shown in fig. 10-a; or the first type of control reference demodulation pilot is used for demodulation of one layer group or port group (i.e. demodulation of the preset part layer), and the second type of control reference demodulation pilot is used for demodulation of other layer groups or port groups (i.e. demodulation of other layers except the preset part layer), as shown in fig. 10-b, where the layer combination port group is generally a corresponding concept; or the first type of control reference demodulation pilot belongs to the first pilot port group set, the second type of control reference demodulation pilot belongs to the second pilot port set, and the first pilot port set is a subset of the second pilot port set, as shown in fig. 10-c.

For the two situations, the first type of reference demodulation pilot frequency is always positioned before the transmission of information, so that the first type of reference demodulation pilot frequency can be used as a basic demodulation pilot frequency, the second type of demodulation pilot frequency can determine whether the second type of demodulation pilot frequency exists according to the requirement, for time delay sensitive services, the first type of reference demodulation pilot frequency can be used for quickly demodulating, for specific situations, such as UE with obvious Doppler, UE with more transmission layer number, and the like, the second type of reference demodulation pilot frequency can be sent according to the requirement, the pilot frequency can be effectively sent according to some characteristics of a terminal, a service and a subsystem, and the utilization rate of the pilot frequency is effectively improved;
