Technical field

The present disclosure relates to the field of communication technology, and in particular to an information transmission and reception method, terminal and network side equipment.

Background technique

When a user equipment (User Equipment, UE, also called a terminal) supports only one service type, the UE will only send an uplink scheduling request (Scheduling Request) when there is no uplink-shared channel (UL-SCH) resource. SR) requests the base station to allocate uplink transmission resources for it. When the UE has UL-SCH resources, the UE can send a buffer status report (Buffer Status Report, BSR) through the Physical Uplink Shared Channel (PUSCH). New data arrives at the requested resource. Therefore, there is no conflict between SR and PUSCH with UL-SCH (transmission time overlap). In the New Radio (NR) system, PUSCH can have different Orthogonal Frequency Division Multiplexing (OFDM) symbol lengths (2-14 OFDM symbols), and the physical uplink control channel for transmitting SR ( Physical Uplink Control CHannel, PUCCH) can be short PUCCH (1/2 OFDM symbol length) or long PUCCH (4-14 OFDM symbol length), and the period of SR can be as small as 2 symbols and as large as 1 to multiple time slots.

When the UE supports different types of services at the same time, the latency and reliability requirements of different services are different (such as enhanced mobile broadband (eMBB) and ultra-reliable and low latency communications, URLLC), when the UE may have UL-SCH resources for one service (such as eMBB), and another service data arrives (such as URLLC), due to low latency requirements, the transmission of BSR on PUSCH may increase the delay, or Due to the long processing time of BSR (BSR tens to hundreds of bits, SR up to 4 bits) and it is too late to transmit on PUSCH, you can consider sending SR to request uplink transmission resources for another service. But if PUSCH is completely discarded, Only transmitting SR will reduce the uplink throughput. In addition, when the Medium Access Control (MAC) layer notifies the physical layer to send SR, PUSCH may have started transmission, so how to implement SR transmission becomes an urgent need to solve The problem.

Detailed ways

In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the present disclosure will be described in detail below with reference to the accompanying drawings and specific embodiments.

In the description of the embodiments of the present disclosure, first, the related technologies related to the embodiments of the present disclosure are described as follows.

Compared with previous mobile communication systems, the future 5th Generation (5G) mobile communication system needs to adapt to more diversified scenarios and service requirements. The main scenarios of New Radio (NR) include enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-high-reliability and ultra-low-latency communications (URLLC). These scenarios suggest the system Requirements for high reliability, low latency, large bandwidth, and wide coverage.

1. Uplink scheduling request (Scheduling Request, SR)

If a user equipment (User Equipment, UE, also called a terminal) has no uplink data to transmit, the base station does not need to allocate uplink resources for the UE, otherwise it will cause a waste of resources. Therefore, the UE needs to tell the base station whether it has uplink data to transmit, so that the base station can decide whether to allocate uplink resources to the UE.

The UE tells the base station whether uplink resources are needed for uplink shared channel (UL-SCH) transmission through the SR, but does not tell the base station how much uplink data needs to be sent (this is reported through the Buffer Status Report (BSR) of). After the base station receives the SR, the amount of uplink resources allocated to the UE depends on the implementation of the base station. The usual approach is to allocate at least enough resources for the UE to send the BSR. The UE needs to tell the base station through the BSR how much data needs to be sent in its uplink buffer so that the base station can decide how much uplink resources to allocate to the UE.

The base station does not know when the UE needs to send uplink data, that is, when the UE will send the SR. Therefore, the base station needs to detect whether there is an SR report on the allocated SR resources. SR is transmitted on Physical Uplink Control Channel (PUCCH) resources, and the PUCCH resource for transmitting SR is transmitted through information element (information element, IE): Uplink scheduling request resource identifier (schedulingRequestResourceId) of uplink scheduling request resource configuration (SchedulingRequestResourceConfig) ) Field configuration. SR resources are configured periodically, and different periods reflect different delay requirements. A UE can be configured with multiple SRs, which are identified by IE: Uplink Scheduling Request Resource ID (SchedulingRequestId), and different SRs correspond to different logical channels (data priority).

2. Physical Uplink Shared Channel (PUSCH)

The PUSCH can be used to carry UL-SCH and uplink control information (Uplink Control Information, UCI). When it is used to carry UL-SCH, that is, PUSCH with UL-SCH, the UE sends uplink data through PUSCH. At this time, the UE already has uplink resources to send data, so the UE does not need to send SR. At this time, if the PUSCH conflicts with the PUCCH, this The PUCCH must be the PUCCH that carries Hybrid Automatic Repeat Request ACK (HARQ-ACK)/Channel State Information (CSI). The UE multiplexes the data with HARQ-ACK and CSI on PUSCH for transmission. . The PUSCH may also be used only to carry aperiodic CSI (aperiodic CSI, A-CSI)/semi-persistent CSI (SP-CSI), that is, PUSCH without UL-SCH, that is, the base station is allocating PUSCH When the resource is used, it indicates that the resource is only used to transmit CSI information, not to transmit UL-SCH. Because the PUSCH at this time is not used for the transmission of service data, when the PUSCH without UL-SCH conflicts with SR, the UE will discard the PUSCH. The SR is transmitted on the PUCCH resource corresponding to the SR.

The present disclosure aims at the problem of how to perform data transmission to ensure communication reliability when PUSCH and SR transmission requirements exist at the same time, and provides an information transmission and reception method, terminal and network side equipment.

As shown in FIG. 1, an embodiment of the present disclosure provides an information transmission method applied to a terminal, including:

Step 101: Send a scheduling request SR through the physical uplink shared channel PUSCH.

It should be noted that the method of sending SR through PUSCH is: SR is transmitted on PUSCH in a punctured manner, and SR is transmitted in punctured manner, which not only ensures reliable transmission of SR, but also reduces the impact on PUSCH transmission.

Normally, when the first priority SR conflicts with the second priority PUSCH time domain resource (that is, there are both PUSCH and the first priority SR transmission demand), the first priority SR is The PUSCH is transmitted in a punctured manner. Specifically, the first priority is higher than the second priority, that is, when the high-priority SR conflicts with the low-priority PUSCH time domain resources, the SR uses the punching method on the PUSCH. Transmission by way of holes.

The following describes the specific implementation process of the embodiments of the present disclosure from the perspective of different punching modes.

Method 1: Punching with resource element (RE) as the unit

In this case, the specific implementation of step 101 is:

Determine the number of coded modulation symbols mapped by each layer of the SR in the PUSCH and the RE position where the coded modulation symbols of each layer are mapped;

The SR is sent through the PUSCH according to the number of coded modulation symbols mapped in each layer and the RE position where the coded modulation symbols of each layer are mapped.

It should be noted that one coded modulation symbol is mapped on one RE, that is, the number of coded modulation symbols mapped by each layer of the SR in the PUSCH refers to the number of REs occupied by the SR in the PUSCH.

Further, the method for determining the number of coded modulation symbols mapped in each layer is specifically as follows: according to the number of bits and offsets of the SR and the number of REs that can be used to transmit SR on the PUSCH, determine the number of SR mapped in each layer in the PUSCH. The number of code modulation symbols.

It should be noted that the offset is determined in one of the following ways:

A11. Configured by radio resource control (RRC);

A12. Instructed by downlink control information (DCI);

A13. Same as the offset when the hybrid automatic repeat request acknowledgement (HARQ-ACK) is transmitted on the PUSCH;

It should be noted that, in this case, the offset used to determine the number of coded modulation symbols for each layer mapping is agreed upon by the protocol to be the same as the offset used when HARQ-ACK is transmitted on PUSCH. Further, HARQ- The offset when the ACK is transmitted on the PUSCH can be configured by RRC or indicated by DCI; it should be further noted that the HARQ-ACK mentioned in this case refers to the high-priority HARQ-ACK.

For example, when Mbit SR(M=log2(k+1), where k represents the number of SRs that overlap with PUSCH time domain resources, in particular, k SRs here refer to k different SR configurations, if it is one SR Multiple candidate positions are configured to overlap with PUSCH time domain resources, k is equal to 1) When transmitting on PUSCH, according to the number of bits of SR, the offset (betaoffset), PUSCH except demodulation reference signal (DMRS) The available RE resources (that is, the number of REs that can be used to transmit SR on the PUSCH) determine the number of REs occupied by the SR, that is, the number of coded modulation symbols ( _Q'SR ) mapped by each layer of the SR in the PUSCH. Among them, betaoffset is used to control the number of REs occupied by SR during puncturing transmission on PUSCH. This parameter can be RRC configuration or DCI indication, it can be configured or indicated separately, or it can correspond to HARQ-ACK transmission on PUSCH. The betaoffset is the same, where, if the HARQ-ACK is of different types or priorities, the SR uses the betaoffset corresponding to the higher priority HARQ-ACK or the betaoffset with the largest betaoffset value.

For example, the following formula can be used to determine the number of coded modulation symbols mapped by each layer of SR in PUSCH with UL-SCH:

Wherein, Q _'SR SR is the number of coded modulation symbols in PUSCH mapped each; O is a number of bits of the SR _SR; _SR is the SR L corresponding cyclic redundancy check (Cyclic Redundancy Check, CRC) bits, when When the number of SR bits is less than or equal to 11 bits, L _SR =0;

Indicated by RRC configuration or DCI; C _UL-SCH is the number of UL-SCH code blocks (code blocks) for PUSCH transmission; if the DCI for scheduling PUSCH includes code block group transmission information (CBGTI) indication field, Indicate not to transmit r-th code block, then K _r =0, otherwise, K _r represents the r-th code block size of UL-SCH on PUSCH;

Is the number of REs available for UCI transmission on OFDM symbol 1 in PUSCH transmission,

Indicates the total number of OFDM symbols included in the Configured Grant PUSCH (CG-PUSCH) transmission, including symbols used for DMRS; for OFDM symbols containing DMRS, if SR cannot be mapped to DMRS OFDM symbols, then

If SR can be mapped on DMRS OFDM symbol then

For OFDM symbols without DMRS,

l ₀ represents the index of the OFDM symbol where the CG-UCI starts to map, that is, the index of the first symbol without DMRS after the first DMRS;

Represents the bandwidth of PUSCH transmission, counted by subcarriers;

The subcarrier used for the phase tracking reference signal (PTRS) in the OFDM symbol 1 in PUSCH transmission.

Further, the determination method of the RE position mapped by the coded modulation symbol of each layer is specifically as follows:

According to the SR mapping rule, determine the RE position where the coded modulation symbol of each layer is mapped;

Specifically, the mapping rule includes one of the following:

B11. Start mapping the SR from the first position of the PUSCH;

Specifically, the first position corresponds to the start symbol position of the physical uplink control channel (PUCCH) where the SR is located;

It should be further explained that in this case, one of the following is used to achieve:

B111. When the SR is mapped to the demodulation reference signal (DMRS) orthogonal frequency division multiplexing (OFDM) symbol of the PUSCH, the SR is mapped to the first RE in the DMRS OFDM symbol, and the first RE is RE other than the RE occupied by DMRS;

That is to say, in this case, SR can be mapped on DMRS OFDM symbols, but when SR is mapped on DMRS OFDM symbols, SR cannot be mapped on REs occupied by DMRS, and only REs not occupied by DMRS can be selected for mapping.

B112. The SR is mapped to other OFDM symbols except the DMRS OFDM symbol;

It should be noted that in this case, SR cannot be mapped to DMRS OFDM symbols.

B12. Starting from the first available non-DMRS OFDM symbol after the first DMRS OFDM symbol of the PUSCH, perform the SR mapping;

B121. The SR can be mapped on the RE occupied by HARQ-ACK;

That is to say, in this case, when the SR is mapped, it does not need to consider whether the HARQ-ACK has been mapped on the PUSCH. Even if it has been mapped, the SR can still occupy the RE used by the HARQ-ACK.

B122. The SR cannot be mapped on the RE occupied by HARQ-ACK;

That is to say, in this case, when the SR is mapped, the HARQ-ACK mapping needs to be considered. If there is HARQ-ACK transmission on the PUSCH, the SR cannot occupy the RE used by the HARQ-ACK.

For example, suppose that M-bit SR is transmitted on the PUSCH, and each layer maps 15 modulation and coding symbols, that is, 15 REs. When the SR cannot puncture PUSCH DMRS symbols and the HARQ-ACK is not transmitted on the PUSCH, the specific RE occupied by the SR The distribution method is shown in Figure 2; when SR cannot puncture PUSCH DMRS symbols, and there is HARQ-ACK on PUSCH, HARQ-ACK starts from the first available non-DMRS OFDM symbol after the first DMRS symbol, and needs to Occupies 16 REs, SR cannot puncture the RE where HARQ-ACK is located. The specific distribution of RE occupied by SR is shown in Figure 3; when SR can puncture PUSCH and DMRS symbols, and there are HARQ-ACK, HARQ- ACK is mapped from the first available non-DMRS OFDM symbol after the first DMRS symbol and needs to occupy 16 REs. SR can puncture the RE occupied by HARQ-ACK. The specific distribution of RE occupied by SR is as follows As shown in Figure 4; when SR can puncture PUSCH DMRS symbols, and there is HARQ-ACK on PUSCH, HARQ-ACK starts mapping from the first available non-DMRS OFDM symbol after the first DMRS symbol, and it needs to occupy 16 RE and SR cannot puncture the RE where the HARQ-ACK is located. The specific distribution mode of the RE occupied by the SR is shown in Figure 5.

Specifically, in Figures 2 to 5, the slashed boxes are RE occupied by DMRS, the grid boxes are RE occupied by SR, the vertical boxes are RE occupied by HARQ-ACK, and the blank boxes are occupied by UL-SCH. The REs with thick grid lines and black boxes are HARQ-ACK REs occupied by SR.

It should be noted that in the present disclosure, if channel state information (CSI) is mapped on the PUSCH, the SR can be mapped on the RE where the CSI is located.

It should be noted that the mapping rule also includes the following:

B21. If on the first OFDM symbol, the number of REs that can be used to transmit SR on the PUSCH is greater than the number of SR to-be-mapped coded modulation symbols, a distributed mapping method is adopted to map the SR to-be-mapped coded modulation symbols on the On the first OFDM symbol of PUSCH;

It should be noted that the first OFDM symbol refers to any OFDM symbol.

B22. If on the second OFDM symbol, the number of SR coded bits that can be mapped on the PUSCH is greater than the number of SR coded bits to be mapped, a distributed mapping method is used to map the SR coded bits to be mapped on the PUSCH. On the second OFDM symbol;

It should be noted that the second OFDM symbol refers to any OFDM symbol.

It should be noted that the number of SR coded bits to be mapped in the above implementation of B22 can be calculated from the number of SR coded modulation symbols to be mapped, specifically, the number of SR coded bits to be mapped = SR coded modulation symbols to be mapped Number × modulation order (Q _m ) × PUSCH transmission layer number (N _L ); it should also be noted that the above B11 and B12 are two different implementation expressions, and their original intentions are the same.

For example, if on a certain OFDM symbol, the number of REs available for PUSCH is greater than the number of remaining punctured SRs, SR punctures PUSCH REs in a distributed manner. Specifically, if the remaining M coded modulation symbols of the SR need to be mapped, and there are N REs on PUSCH OFDM symbol 1 that can be used for SR transmission, then the coded modulation symbols of SR are mapped on the REs available for SR transmission for every d REs, where d =floor(N/M), for example, in Figure 2 the first available non-DMRS OFDM symbol after DMRS, the number of REs that can be used for SR transmission is 12, and SR requires 15 REs. At this time, d=1, that is, every Each RE will be mapped to the coded modulation symbol of SR. On the next symbol, SR still has 3 coded modulation symbols remaining. At this time, there are 12 REs on PUSCH that can be used to transmit SR, then d=4, for example, In Figure 4, on the first symbol of SR mapping, that is, the DMRS symbol, there are 6 non-DMRS REs on this symbol, that is, 6 REs can be mapped to SR, and SR has 15 coded modulation symbols to be mapped at this time , So d=1. On the first OFDM symbol after the DMRS OFDM symbol, SR still has 9 coded modulation symbols remaining. Because SR can puncture the RE occupied by HARQ-ACK, the symbol on PUSCH has 12 Each RE can be used to transmit SR, then d=1.

Method 2: Use the SR transmission format for punching

In this case, the specific implementation of step 101 is:

According to the transmission format of the SR on the PUCCH, the SR is mapped on the PUSCH; and the PUSCH mapped with the SR is transmitted.

It should be noted that in this case, a certain physical resource block (PRB) allocated by the SR on the PUSCH is transmitted in the format transmitted on the PUCCH, that is, the format of the SR on the PUCCH For transmission, SR is also punctured in PUSCH according to the same format.

It should also be noted that because SR corresponds to multiple candidate resource locations, each candidate resource location does not necessarily perform SR transmission. Only when there is a data transmission demand, the terminal sends the SR to the network side device at the candidate resource location, and further , The implementation of step 101 is:

The SR corresponds to at least one candidate transmission position, and when the SR is transmitted on the first candidate transmission position, the SR transmitted on the first candidate transmission position is sent through the PUSCH;

Wherein, the first candidate transmission position is one of the at least one candidate transmission position.

That is to say, when a PUSCH overlaps multiple candidate transmission positions configured for one SR, the terminal only transmits the SR once through the PUSCH when the corresponding candidate position is an actual SR (positive SR) transmission.

For example, as shown in FIG. 6 and FIG. 7, the SR period is 2 symbols, the time domain symbol length of the PUCCH corresponding to the SR is 2; the symbol length of the PUSCH is 8, and the PUSCH overlaps with the 4 candidate transmission positions of the SR. When the SR is negative at all candidate transmission positions (that is, there is no SR transmission at the candidate transmission position), the terminal does not need to transmit the SR, and therefore does not need to puncture the PUSCH to transmit the SR. When a certain candidate transmission position is positive SR, the UE transmits SR on PUSCH. When the physical layer SR is positive, the terminal needs to transmit SR on PUSCH at this time. The terminal may have started or will start transmitting PUSCH, so it cannot stop PUSCH. , The rate matching method cannot be used (the UE is ready for data transmission on the PUSCH, and cannot or does not have enough time to prepare the data again), but can only use the puncturing method to transmit SR; the diagonal lines in Figure 6 and Figure 7 If the candidate transmission position indicated by the box has SR transmission, the SR puncture transmission is performed on the time domain corresponding to the candidate transmission position of PUSCH; the horizontal box is the candidate transmission position without SR transmission, and the grid box It is the start position of the PUSCH in the time domain corresponding to the actual transmission position of the SR (ie, the candidate transmission position of the actual transmission of the SR).

Method 3: Modulate SR on a certain column of DMRS/some DMRS of PUSCH for transmission

In this method, positive SR is transmitted through RE occupied by DMRS on PUSCH. Specifically, SR is transmitted through DMRS sequence on PUSCH. SR modulation symbols can be used to modulate the DMRS sequence, or different DMRS sequences can be used to indicate whether there is positive SR. At the same time, if there are multiple DMRS OFDM symbols on PUSCH, SR can be modulated on one or part of DMRS OFDM symbols.

In the following, taking mode one as an example, when SR starts from the OFDM symbol position corresponding to SR PUCCH, puncturing and mapping on PUSCH. As shown in Figure 8 and Figure 9, the SR period is 2 symbols, and the symbol length of SR PUCCH is 1. In the overlapping part with PUSCH, the SR is positive at the first SR candidate transmission position, and the SR is from the corresponding OFDM The symbol position starts to be punctured and transmitted on the PUSCH (corresponding to the second OFDM symbol of the PUSCH). Figures 8 and 9 are schematic diagrams of mapping modes where SR cannot puncture DMRS symbols, and SR can use REs other than DMRS RE on DMRS symbols; the slashed boxes in Figures 8 and 9 are REs occupied by DMRS, The grid box is the RE occupied by SR, the horizontal box indicates the candidate transmission position of SR, and there is no SR transmission at this position, the vertical box indicates the actual transmission position of SR, and the black box indicates the actual transmission with SR The start position of the PUSCH corresponding to the position in the time domain.

Taking Mode 2 as an example below, when the SR PUCCH conflicts with the PUSCH time domain resource, if it is a positive SR, the terminal uses a part of the PRB allocated by the PUSCH to transmit the PUCCH at the symbol position of the SR PUCCH. That is, the terminal transmits SR on part of the PRB of the PUSCH, and the transmission mode is the same as on the original PUCCH (except for the PRB resource block position), that is, if the SR PUCCH is PUCCH format 0, the SR is transmitted in the transmission mode of PUCCH format 0, and use A PRB of PUSCH, for example, as shown in Figure 10, the terminal uses the first or last PRB allocated to transmit SR. The vertical box in Figure 10 indicates the PRB that transmits SR, and the horizontal box indicates that there is no SR transmission. Candidate transmission position, the grid box is the time domain start position of the PUSCH corresponding to the candidate transmission position for actual SR transmission. It is worth noting that if the PUCCH corresponds to multiple OFDM symbols at this time, the UE uses continuous OFDM symbols when transmitting on the PUSCH, that is, the UE can puncture DMRS symbols, including DMRS RE.

It should be noted that, in order to ensure that the terminal and the network side device have the same understanding, which method the terminal uses to send the SR, the network side device also uses the corresponding method to receive.

It should be noted that the embodiments of the present disclosure provide a method for SR transmission on PUSCH to ensure that when there is a high-priority SR transmission demand, the terminal can perform high-priority SR transmission in time, which reduces the high priority. The SR transmission delay reduces the impact on PUSCH transmission and improves the effectiveness of the communication system.
