Description

De-channel multiplexing method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for demultiplexing channels.

Background

In the conventional 5G protocol, PUSCH (physical uplink shared channel ) defines UCI (Uplink Control Information, uplink control information) information such as ACK (acknowledgement message), CSI (Channel State Information ) 1, CSI2, and SCH information, respectively, so that various channel information must be separated (i.e., demultiplexing of information is implemented) in the processing of the receiver. Since the concept of resource sets is defined in the fifth generation mobile communication system (the 5th generation wireless systems,5G) protocol and mapping must be performed in the order of ACK, CSI1, CSI2, and SCH, demapping must also be performed in the order of ACK, CSI1, CSI2, and SCH. In order to separate UCI and SCH information, a receiver in the prior art may calculate, in advance, specific mapping information of each Resource Element (RE) position according to a method of multiplexing a transmitting end according to a receiving manner of other information in the prior art, and then separate received data according to an indication of the position information; namely, the resource positions for receiving UCI information and SCH information are calculated first, and after the UCI information and the SCH information are received at each resource position, the information is separated according to the relation between the position of the received data and the information classification.

However, the above-mentioned information separation method adopted by the receiver not only needs to buffer and indicate the location information, but also introduces unnecessary processing consumption due to the fact that the location information of each RE is calculated in advance. In particular, in a multi-user scenario, each user needs to calculate the position information in advance, so that the operation amount gradually increases with the increase of the users. The existing processing method has the problem of low resource consumption and high parallelism.

Detailed Description

The manner in which the receiver in the existing 5G communication technology separates UCI information from SCH information is: and calculating specific mapping information of each resource position in advance according to a transmitting end multiplexing method, and then separating the received data according to the indication of the position information. This approach requires pre-learning of the correspondence between the stored location information and the SCH information and UCI information, and also requires calculation of the location information of each RE in advance before the UCI and SCH information are received, which can be seen to require the introduction of much unnecessary processing consumption.

Based on the above problems in the prior art, the embodiment of the present application provides a method for de-channel multiplexing, where the overall idea of the method is that:

each time CUI or SCH information is received, position information (i.e., a starting position) of an RE of CUI information and SCH information is obtained in real time, and then, through the starting position and a CUI information and SCH information transmission rule specified by a protocol, resource positions of respective information can be simply estimated, so that each CUI information and SCH information can be analyzed one by one. Therefore, consumption caused by early calculation can be avoided, and meanwhile, the real-time calculation can be performed without caching position information, so that unnecessary storage space is saved. Particularly, for a multi-user scene, RE position information corresponding to each user does not need to be calculated in advance, and when a certain user is reached, the RE position information is calculated in real time, so that the storage space is saved, and the operation amount is reduced.

Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The embodiments of the present application may be applied to a fifth generation mobile communication system (the 5th generation wireless systems,5G).

For the sake of understanding the embodiments of the present application, a description will be given first by taking the network device structure shown in fig. 1 as an example. Fig. 1 shows a schematic diagram of a network device suitable for the method provided in the embodiment of the present application. As shown in fig. 1, the network device includes: antenna 101, radio frequency device 102, and baseband device 103. Antenna 101 is coupled to radio frequency device 102. In the uplink direction, the radio frequency device 102 receives information transmitted from the terminal device via the antenna 101, and transmits the information transmitted from the terminal device to the baseband device 103 for processing. In the downlink direction, the baseband device 103 processes information of the terminal device and sends the processed information to the radio frequency device 102, and the radio frequency device 102 processes information of the terminal device and sends the processed information to the terminal device through the antenna 101.

The method provided in the embodiments of the present application is applied to a receiver of the baseband apparatus 103, where the baseband apparatus 103 may include one or more processing elements 1031, for example, including a main control CPU and other integrated circuits. In addition, the baseband apparatus 103 may further include a storage element 1032 and an interface 1033, where the storage element 1032 is used to store programs and data; the interface 1033 is used to interact information with the radio frequency device 102, such as a common public radio interface (common public radio interface, CPRI).

Based on the structure of the network device, the method and the device provided in the embodiments of the present application are described in further detail below with reference to the accompanying drawings and specific application scenarios:

example 1

As shown in fig. 2, an embodiment of the present application provides a method for demultiplexing channels, which is suitable for a base station to parse channel information sent by a certain UE, where the method specifically includes the following implementation steps:

step 201, determining an initial index of a resource element RE corresponding to a channel information sequence; wherein the channel information sequence includes at least one channel information including UCI and SCH;

in this example, the channel information sequence may be an ACK sequence; in the transmission process of ACK, the information of a plurality of ACKs in the ACK sequence needs to be distributed at intervals, the first ACK information and the second ACK information represent 2 data information of the ACK sequence, all ACK data information are arranged to be the ACK data sequence, and the data content to be expressed by the ACK sequence information is carried in the sequence.

The channel information in this embodiment may include: UCI information and SCH information; more specifically, the UCI information further includes at least one of ACK, CSI1, and CSI 2.

Because the concept of resource set is defined in the existing protocol, the ACK, the CSI1, the CSI2 and the SCH are carried out according to the sequence of the ACK-CSI 1-CSI 2-SCH when being mapped, and the starting positions of the ACK, the CSI1, the CSI2 and the SCH and the position intervals among the ACK, the CSI1, the CSI2 and the SCH in one mapping transmission can be determined according to the rule and the rule set when being mapped. Thus, the initial index of the resource element RE corresponding to the channel information sequence can be determined according to the rule, and the index position is the initial position and is used for calculating the initial index of the channel information (i.e. the position of the RE receiving the channel information) in the channel information sequence.

The protocol also defines the manner in which a plurality of channel information of the same type are transmitted, so that after the starting position of the first channel information is determined, the next position can be determined by a fixed interval (D parameter) between the two information. For example, in the ACK sequence, if the initial index of the first ACK is determined, the RE initial index (or referred to as RE index) of the next ACK information may be calculated according to the interval (i.e., D parameter) between two ACK information specified in the protocol.

Step 202, determining that channel information exists in a resource group, and matching each initial index with an index of RE in the resource group according to the sequence of the initial indexes; wherein, the resource group comprises a plurality of REs, and each RE corresponds to an index;

in the embodiment of the present application, one resource group refers to a set of a plurality of REs included on a time axis; according to the set forming rule, the scheduling of ACK and CSI starts from the first resource group, and the RE initial indexes (i.e. the set initial RE indexes) corresponding to the ACK, CSI1, CSI2 and SCH are initially refreshed to the configured starting positions in each resource group.

Each resource group may include (k+1) REs, with the RE index of each clk starting from RE0 to REk ending, with RE index of each clk incremented by 1.

Based on the kind included in the above channel information, since the processes with CSI2 and without CSI2 are not identical, and the resources of CSI2 are indicated by CSI 1. Therefore, if the CSI2 resource is needed to be extracted, the CSI1 resource is extracted, and then the CSI2 resource is found through the internal data indication of the CSI 1. Based on the principle, in the embodiment, when specifically judging whether the current RE has channel information, it may be:

firstly judging whether the resource group has CSI2 and SCH resources, if not, directly jumping to the initial RE of the next resource group to continue the judgment. And after all the resource groups are finished, finishing ACK and CSI1 analysis of a certain UE.

Step 203, if the initial index corresponding to the first channel information in the channel information sequence is matched with the index of the current RE, the first channel information is parsed from the current RE.

If the first channel information is ACK information, after the initial index is determined to be matched with the index of the current RE, determining that the current RE correspondingly transmits one piece of ACK information, and correspondingly generating a data indication mark of the ACK, wherein the indication mark is used for indicating that the current RE analyzes one piece of ACK information.

Step 204, updating the initial index of each channel information in the channel information sequence, and determining the initial index of each channel information in the channel information sequence in the current resource group and the next resource group.

The demultiplexing process provided in the embodiment of the present application is a process of gradually calculating demultiplexing according to a transmission sequence of channel information, after determining an RE index corresponding to a first channel information in a channel information sequence, determining a demultiplexing position of other channel information through a protocol rule, that is, a process of updating an initial index in the embodiment of the present application, and according to a channel information type and a transmission mode of channel information corresponding to the embodiment of the present application, the specific implementation includes:

if the channel information sequence includes multiple channel information, and the multiple channel information are arranged according to the protocol, the same channel information may be sent multiple times (for example, the ACK sequence includes multiple ACK information, and a fixed interval is between the two ACK information), and updating the initial index of each channel information in the channel information sequence according to the above principle in the embodiment of the present application includes:

for a case where multiple pieces of information are sent in the same class (for example, one ACK sequence includes multiple pieces of ACK information, where multiple pieces of ACK information are mapped to REs at fixed intervals), the specific implementation of index update may be:

secondly, for different channel information continuously arranged in the same channel information sequence, calculating indexes of each channel information according to fixed intervals among each channel information in the channel sequence, wherein the specific implementation can be as follows:

The above-mentioned index updating manner is described in further detail below with respect to specific channel information, and since the concept of resource aggregation is defined in the existing 5G protocol, that is, the terminal device must map in the order of ACK, CSI1, CSI2, and SCH when transmitting the channel information, so the base station side must also demap in the order of ACK, CSI1, CSI2, and SCH when demapping, based on the scheme provided in the embodiment of the present application, the method may also be implemented in the order when demapping (demultiplexing) the channel information, which corresponds to the implementation manner in this embodiment:

if indexes of a plurality of REs included in the current resource group are matched with initial indexes of channel information in the channel information sequence, analyzing each piece of channel information according to the sequence of the channel information in the channel information sequence.

Further, for demultiplexing each information of specific ACK, CSI1, CSI2, SCH, the specific implementation provided in the embodiment of the present application may be:

(1) First, it is determined whether the de-multiplexing is ACK information (the ACK information may be one of ACK information sequences, which may include a plurality of ACK information, of course), and if the index corresponding to the current RE matches the initial index corresponding to the ACK information, one ACK information is parsed from the current RE. And adds Dack as RE position of next ACK based on index corresponding to current RE (or initial index corresponding to first channel information), where Dack is mapping interval length (D parameter) of adjacent 2 pieces of ACK information specified by protocol.

Because the current RE cannot be mapped to other channel information after being mapped to the ACK information, the index corresponding to the current RE is not included in the resource statistical range of other channel information in the channel information sequence, and for other channel information, an interval value is added on the basis of the initial index of the current RE, which may be added with 1 in this example. If the ACK information in the channel information sequence also comprises the CSI1/CSI2, adding 1 to the initial indexes of REs of the CSI1 and the CSI2; in addition, in order to indicate the mapping relationship between the REs and the channel information, after determining that the current RE corresponds to the ACK information, the embodiment further sets an ack_data_flag flag, where the ack_data_flag is used to indicate whether the RE corresponds to the ACK information, and if ack_data_flag=1, indicates that the current RE is mapped to the ACK information.

(2) If it is determined that the index corresponding to the current RE and the ACK information is not matched, further determining according to the order, whether the index of the channel information after ACK of the CSI or the like is matched with the index of the current RE according to the mapping rule may be specifically implemented as follows:

among the information mapped by the REs, the demodulation reference signal (Demodulation Reference Signal, DMRS) has the highest priority, and other information cannot be RE-mapped onto the REs once the REs are mapped to the DMRS. The determination of whether CSI maps to the current RE may be:

and judging whether the current RE is mapped to the DMRS, if so, determining that the current RE does not comprise channel information, and updating the initial index according to the index interval between the channel information in the channel information sequence. The specific implementation can be as follows:

a, for CSI1 demultiplexing position determination and index updating, may be:

firstly judging whether the current RE is the position for mapping the DMRS, if so, directly setting the csi1_data_flag corresponding to the current RE to be 0, namely indicating that the channel information mapped by the current RE is not CSI1, and the initial index Kcs1 =Kcsi1+1 corresponding to the CSI1;

if the current RE is not the location of the mapped DMRS, judging whether the initial index of the CSI1 is matched with the index of the current RE: if so, indicating that the CSI1_data_flag mark corresponding to the current RE is 1, and mapping the current RE to CSI1; if there is no match, csi1_data_flag is set to 0.

If there is a match, it is further necessary to update the initial index, including: updating an initial index (Kcs 1) corresponding to the CSI1 to obtain an RE index corresponding to the next CSI1, wherein Kcs1 =Kcsi1+Dcsi1, and Dcsi1 is an interval value between the front CSI1 and the rear CSI1; the initial index (Kcs 2) of CSI2, which is in the order of CSI1 after the demultiplexing in the channel information sequence, is also updated, kcs2 =kcsi2+1.

B, for CSI2 demultiplexing position judgment and index updating, can be:

firstly judging whether the current RE is the position for mapping the DMRS, if so, directly setting the csi2_data_flag corresponding to the current RE to be 0, namely indicating that the channel information mapped by the current RE is not CSI2, and the initial index Kcs2 =Kcsi2+1 corresponding to the CSI2;

if the current RE is not the position for mapping the DMRS, judging whether the initial index of the CSI2 is matched with the index of the current RE, and if so, setting the csi2_data_flag mark position corresponding to the current RE as 1 to indicate that the current RE maps the CSI2; and if the csi2_data_flag is not matched, setting the csi2_data_flag to 0.

If there is a match, it is further necessary to update the initial index, including: updating an initial index (Kcs 2) corresponding to the CSI2 to obtain an RE index corresponding to the next CSI2, wherein Kcs2 =Kcsi2+Dcsi2, and Dcsi2 is an interval value between the front CSI2 and the rear CSI2; if the CSI2 in the channel information sequence is the last channel information, the initial index update only determines the initial index of the next CSI 2.

The interval value between the channel information in the channel information sequence mentioned in the above embodiment is determined according to the definition of the protocol, and according to the definition of the protocol, the initial index and the D parameter of the channel information in each resource group can be calculated, and these parameters can be directly calculated according to the parameters. In this way, the embodiment of the application can obtain the initial index and the D parameter of ACK, CSI1, CSI2, and SCH on each resource group respectively. And then, according to the embodiment of the application, carrying out real-time calculation on each RE to finally obtain the final control or data information mapped by each RE.
