Description

Data transmission method and equipment for wireless communication system
Technical Field
The present application relates to the field of wireless communication technologies, and in particular, to a method and device for transmitting data in a wireless communication system.
Background
SPS (Semi-Persistent Scheduling) Scheduling and Configuration Grant (CG) PUSCH Scheduling allows the periodic allocation of PDSCH/PUSCH resources to a specific UE through one physical downlink control channel Scheduling.
The HARQ process ID of the SPS PDSCH/configuration granted PUSCH is determined based on the pre-configured resource location of the data transmission. Although there are multiple data transmission occasions in one configuration period, the HARQ ID obtained by any transmission occasion occupied by the actual transport block in one configuration period is the same.
Packet arrivals for XR services are periodic, but the actual arrival time of a packet may experience jitter, causing it to arrive randomly within a jittered time window. Therefore, unlike the prior art in which the SPS configuration/CG PUSCH only includes one data transmission opportunity in one period, in order to satisfy the characteristic of XR service arrival time jitter, multiple data transmission opportunities may be configured in one period of the SPS configuration/configuration grant PUSCH, so as to satisfy the requirement that a service packet can be transmitted in time after arrival.
In addition, the data packet size for XR traffic may vary over time, sometimes being large and sometimes being small. On the basis that the SPS configuration/CG PUSCH is realized by a plurality of SPS PDSCH/PUSCH transmission occasions in one period, the number of PDSCH/PUSCH occupied by the data packet is determined by the size of the data packet.
If the method for determining the HARQ process ID is adopted according to the prior art, the HARQ process IDs corresponding to the SPS PDSCH/PUSCH transmission opportunities for multiple times in one SPS/CG PUSCH period are the same. HARQ process management will be disturbed if the multiple SPS PDSCH/PUSCH are used to transmit different transport blocks. For example, when the PUSCH at time t1 and time t2 uses the same HARQ process ID but different transport blocks are transmitted, the data block TB2 at time t2 in the data storage space of the HARQ process ID replaces the data block TB1 at time t1, so that the TB1 cannot implement retransmission data combining.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, 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 application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic diagram illustrating a resource allocation method according to the prior art.
SPS (Semi-Persistent Scheduling) Scheduling and Configuration Grant (CG) PUSCH Scheduling allows the periodic allocation of PDSCH/PUSCH resources to a specific UE through one physical downlink control channel Scheduling. The specific process of SPS scheduling is that the base station uses the PDCCH scrambled by the CS-RNTI to specify the radio resource used by the UE (referred to as SPSPDSCH resource herein), and every period, the UE uses the SPS PDSCH resource to receive or transmit data, and the base station does not need to issue the PDCCH to specify the allocated resource. There are two ways for CG PUSCH configuration transmission: one is CG PUSCH type 1, resources for transmitting the grant are all provided by RRC, and the UE stores the configuration and uses it as a grant configuration when there is uplink data transmission. The other type is CG PUSCH type 2, the information such as the cycle, HARQ serial number and the like of the CG PUSCH is configured by an RRC layer, and then the configuration is activated or deactivated by a physical downlink control channel PDCCH. The PDCCH for activating or deactivating the CG PUSCH includes the resource occupied by the PUSCH in time and frequency, and the time position of the first CG PUSCH. And the UE can use the CG PUSCH resource after acquiring the activation information.
For example, fig. 1 is a schematic diagram of CG PUSCH type 2, and after acquiring a PDCCH activating a CG PUSCH, a UE periodically occupies a CG PUSCH resource to transmit uplink information. Similar to CG PUSCH type 2, SPS PDSCH is also information such as periodicity, HARQ sequence number, etc. of SPS PDSCH configured by RRC by the base station, and then configuration is activated or deactivated by PDCCH.
The HARQ process ID of the SPS PDSCH/configuration granted PUSCH is determined based on the pre-configured resource location of the data transmission. Still taking the configuration of the authorized PUSCH as an example, the configuration information includes a configuration authorization period, a configuration number of HARQ processes used by the authorized PUSCH, and the like. The HARQ process ID used for one PUSCH transmission is determined by the first symbol position of the PUSCH, and specifically:
HARQ process ID = [ floor (X/period) ] modulo Y, where:
x = (system frame number X number of consecutive slots per frame X number of consecutive symbols per slot + slot index in current frame X number of consecutive symbols per slot + symbol index in current slot);
y is the number of HARQ processes used by the configuration authorization PUSCH;
floor is a round-down operation and modulo is a modulo operation.
If the configuration information indicates that the transmission block is repeatedly transmitted on the grant-configured PUSCH for multiple times, the same HARQ process ID is used for the multiple repeated transmissions. The above-mentioned "symbol index in current slot" refers to the first symbol index of the PUSCH occasion for the first transmission. I.e., the HARQ process ID is determined primarily based on the time of the transmission opportunity configured to the UE for uplink data transmission.
Likewise, the HARQ process ID is determined by the time of the transmission opportunity for downlink data transmission at the time of SPS PDSCH transmission.
Fig. 2 (a) - (b) are schematic diagrams illustrating XR service packet to transmission opportunity mapping relationships, where (a) multiple data transmission opportunities are configured under jitter conditions, and (b) data packet sizes vary;
packet arrivals for XR services are periodic, but the actual arrival times of packets may experience jitter, causing their arrival times to arrive randomly within a jittered time window. Fig. 2 (a) is an example where a first jitter time window begins at time t0, where XR data packets may arrive within this time window between t0 and t4, where XR data packets arrive at time t 1. The next XR data packet arrives after time P, and the next XR data packet may arrive at any time within the jitter time window between t5 and t 9. The next XR data packet arrives at time t7 in the figure. Therefore, unlike the prior art in which the SPS configuration/CG PUSCH only includes one data transmission opportunity in one period, in order to satisfy the characteristic of XR service arrival time jitter, multiple data transmission opportunities may be configured in one period of the SPS configuration/configuration grant PUSCH, so as to satisfy the requirement that a service packet can be transmitted in time after arrival.
Furthermore, the data packet size for XR services may vary over time, sometimes being large and sometimes being small. On the basis that the SPS configuration/CG PUSCH is realized by a plurality of SPS PDSCH/PUSCH transmission occasions in one period, the number of PDSCH/PUSCH occupied by the data packet is determined by the size of the data packet. As shown in fig. 2 (b), in the first period of CG PUSCH, XR data packets occupy 3 PUSCHs for transmission of TB1, TB2, and TB3, respectively. In the next CG PUSCH period, the XR data packet occupies 1 PUSCH transmission TB4. XR traffic can also be said to satisfy the quasi-periodic characteristics. Quasi-periodic data refers to data whose burst window satisfies periodicity. For example, a jitter window has a length of L, a burst window is composed of a plurality of jitter windows with a period of P, and a data burst occupies a part of or all of data transmission opportunities in the jitter window.
FIG. 3 is a flow chart of an embodiment of the method of the present application;
in an embodiment of the first aspect, the present application provides a data transmission method in a wireless communication system, including the following steps 110 to 140:
step 110, determining a periodic configuration resource, where each period includes N data transmission occasions, and each data transmission occasion is used for 1 transmission block.
Preferably, the configuration information includes a maximum value of M.
And step 120, in the ith period, determining M times of actual data transmission corresponding to M data transmission opportunities occupied by the data.
Preferably, the resources of the M actual data transmission occasions are adjacent in time sequence.
Step 130, determining the HARQ process number of the M actual data transmissions, wherein the process number ID of the jth actual data transmission j Is in one-to-one correspondence with j, j = 1-M, M>1。
Preferably, the method according to any embodiment of the present application determines a basic HARQ process number corresponding to an ith period, and a process number ID of the jth actual data transmission j And jointly generating the base HARQ process number and j.
For example, the base HARQ process number of the i-th period is determined by a time position of a first data transmission occasion of the N data transmission occasions.
For another example, the HARQ process number of the j-th actual data transmission is the sum of the basic HARQ process number and j.
It should be noted that the "one-to-one correspondence" in the present application refers to a unique correspondence between two set elements, which is colloquially referred to as one-to-one, i.e., one-to-one mapping. As A, B two sets, each element in B has a primitive image, and different elements in set a have different images in set B, a one-to-one correspondence, i.e., one-to-one mapping, between set a and set B is established.
And step 140, identifying the actual data transmission of M times in the ith period according to the determined HARQ process number.
Preferably, the j-th opportunity data transmission includes control information, and the control information is used to determine a value of j.
In the present application, the transmission speed for realizing the actual data transmission may be SPS PUSCH, SPS PDSCH, or CG PUSCH.
It should be noted that the above steps are applied to a network entity of a wireless communication system, including a terminal side device, a network side device, an intermediate device, or other higher-layer service devices; the above steps can also be used for providing a service device for information processing for the network entity equipment; the above steps can also be used in any device, system, subsystem, circuit, chip or software entity that provides information receiving, sending, identifying, and processing for the terminal side device or the network side device.
The method can be used for data information between a first device (gNB) and a second device (UE).
Fig. 4 (a) - (b) are schematic diagrams of HARQ identifiers for opportunity data transmission implemented to carry XR data packets according to the present application, where (a) non-actual data transmission participates in HARQ ID numbering, and (b) non-actual data transmission does not participate in HARQ ID numbering;
taking N (N ≧ 2) PUSCH transmission occasions within one CG PUSCH period as an example, using the prior art, the floor (X/period) corresponding to the N PUSCHs is the same, and correspondingly, the N PUSCH transmission occasions correspond to the same HARQ process ID. Assuming that there is always an actual PUSCH transmission only once for N PUSCH transmission occasions, its HARQ process ID may be determined using existing techniques. However, under the dual influence of the jitter of the data packet arrival time of the XR service and the variable information amount of the data packet, the practical situation that N times of PUSCH transmission occasions are possibleThe PUSCH transmission times are M,1 is less than or equal to M<And N is added. If different HARQ process IDs are always allocated to N PUSCH transmission occasions, the complexity of HARQ process management may be high and the efficiency may be low. As shown in fig. 4 (a), N =4. If t is 0 、t 1 、t 2 、t 3 The HARQ process IDs corresponding to the 4 PUSCH transmission opportunities are 0, 1, 2 and 3 respectively, and the actual PUSCH transmission only occurs at t 1 、t 2 、t 3 But possibly at t to avoid data packets 0 Upon arrival, the base station needs to ensure that at t, using HARQ process #0 0 The use of HARQ process #0 was released previously. Similarly, the base station needs to be guaranteed to be at t 1 、t 2 、t 3 、t 4 、t 5 、t 6 、t 7 The use of HARQ processes #1, #2, #3, #0, #1, #2, #3 was released separately before, which would have an impact on both the flexibility and efficiency of the scheduling. Similarly, if a HARQ process number is allocated to each PUSCH transmission opportunity regardless of actual PUSCH transmission, it is required to ensure that the allocated HARQ process number is released and can be used by dynamically scheduled data some time after the semi-statically configured transmission opportunity.
The invention conception of the application is that when CG PUSCH resources are configured, N (N is more than or equal to 2) times of PUSCH transmission opportunities exist in a CG PUSCH period, and M is more than or equal to 1 and less than or equal to N times of actual PUSCH transmission correspondingly. And determining the HARQ process ID corresponding to the jth actual PUSCH in the CG PUSCH period by j. As shown in fig. 4 (b), t is the first period 1 、t 2 、t 3 Corresponding to TB1, TB2, TB3, and the HARQ process IDs are # x, # x +1, # x +2, respectively.
Similarly, the HARQ process ID corresponding to multiple PDSCH transmissions within an SPS period is determined by the number of actual PDSCH transmissions within the SPS period.
Fig. 5 is a flowchart of an embodiment of a method of the present application for a network side device.
The method according to any one of the embodiments of the first aspect of the present application, for a network side device, includes the following steps 210 to 240:
step 210, sending configuration information, where the configuration information is used to determine a periodic configuration resource, each period includes N data transmission occasions, and each data transmission occasion is used for 1 transmission block;
step 220, in the ith period, determining M actual data transmissions corresponding to M data transmission opportunities occupied by the data.
And M is more than or equal to 1 and less than or equal to N times of actual data transmission at the N transmission occasions. Or, at least one period of the periodic configuration resources has M transmission opportunities, and 1<M is not more than N. Or, at least one period in the periodic configuration resources has M transmission opportunities, and 1-M-n.
Step 230, determining the HARQ process number of the M actual data transmissions, wherein the process number ID of the jth actual data transmission j Is in one-to-one correspondence with j, j = 1-M, M>1。
Preferably, a base HARQ process number corresponding to the ith period is determined. The HARQ process number of the first actual data transmission is a basic HARQ process number, and the HARQ process number of the j (j is more than or equal to 1 and less than or equal to M) actual data transmission is determined by j and the basic HARQ process number.
And 240, identifying M times of actual data transmission in the ith period according to the determined HARQ process number.
Fig. 6 is a flow chart of an embodiment of the method of the present application for a terminal side device.
The method according to any one of the embodiments of the first aspect of the present application, for a terminal side device, includes the following steps 310 to 340:
step 310, obtaining configuration information, where the configuration information is used to determine a periodic configuration resource, each period includes N data transmission occasions, and each data transmission occasion is used for 1 transmission block.
Optionally, the periodic configuration resource is an SPS resource or a configuration grant PUSCH.
Optionally, the configuration information includes a maximum value of M.
And step 320, in the ith period, determining M actual data transmissions corresponding to the M data transmission opportunities occupied by the data.
The N transmission occasions have M which is more than or equal to 1 and less than or equal to N actual data transmission times,
optionally, the resources of the transmission occasions of the M actual data transmissions are adjacent to each other in time.
Step 330, determining the HARQ process number of the M times of actual data transmission, wherein the process number ID of the jth actual data transmission j Is in one-to-one correspondence with j, j = 1-M, M>1。
Determining a basic HARQ process number corresponding to the ith period;
wherein, the HARQ process number of the first actual data transmission is the basic HARQ process number, and the HARQ process number of the j (j is more than or equal to 1 and less than or equal to M) actual data transmission is determined by j and the basic HARQ process number;
optionally, the base HARQ process number of the ith period is determined by a time position of a first transmission occasion of the N transmission occasions, for example, but not limited to, using formula (1).
Optionally, the HARQ process number of the j-th actual data transmission is equal to the sum of the basic HARQ process number and j.
And step 340, identifying M times of actual data transmission in the ith period according to the determined HARQ process number.
And correspondingly transmitting the M times of actual data in the ith period according to the determined HARQ process number. Optionally, the jth actual data transmission includes control information, and the control information is used to determine a value of j.
In this embodiment, the configuration information is used to determine a periodic configuration resource. For example, the configuration information includes an SPS configuration message and scheduling information for activating SPS configuration. Or, the configuration information is an RRC message corresponding to CG PUSCH type 1. Or the configuration information is an RRC message corresponding to the CG PUSCH type 2 and a message for activating the CG PUSCH type 2. In this embodiment, the periodic configuration resource refers to several resources with a period P. N data transmission opportunities are included in the time of each cycle. Accordingly, there is a transmission resource corresponding to each data transmission occasion.
Actual data transmission may or may not be performed on the transmission resources corresponding to the N data transmission opportunities in each period. The method for determining the number of the HARQ process according to the prior art comprises the following steps:
HARQ process ID = [ floor (X/period) ] modulo Y (1)
The HARQ process numbers corresponding to the N data transmission opportunities are the same. In this embodiment, first, the basic HARQ process number corresponding to the configured resource period where the multiple data transmission occasions are located is determined. The HARQ process number for the actual data transmission is determined based on the base HARQ process number. As an implementation manner, the base process number corresponding to the ith period can be determined by using the time position of the Kth (K is less than or equal to N) transmission time in N data transmission opportunities. K is preset. Preferably K =1. The base HARQ process number may be determined using, for example, equation (1) and the time position of the kth data transmission opportunity. For example, the number of the basic HARQ process corresponding to the ith period is determined to be x.
The base HARQ process number corresponding to the ith period is x, and is used to determine the HARQ process number corresponding to the actual data transmission of the ith period. In N transmission timers in the ith period, M (M is more than or equal to 1 and less than or equal to N) actual data transmission time is provided. Wherein, the HARQ process number of the first actual data transmission is the basic HARQ process number, and the HARQ process number of the j (j is more than or equal to 1 and less than or equal to M) actual data transmission is determined by j and x. Process number ID of jth actual data transmission j And j is in one-to-one correspondence. The process number ID of the unique j-th actual data transmission can be jointly generated by using the base HARQ process number and j j . For example, the number of HARQ process for the j-th actual data transmission is j + x. When M times of actual data are transmitted in the ith period, the HARQ process numbers corresponding to the M times of actual data may be used.
Because the network adopts the parallel stop and wait mode of the multiple HARQ processes, each HARQ process number corresponds to a respective storage space and is used for retransmission and combination for multiple times. One HARQ process number may be used for data transmission on the periodically configured resources, and may also be used for dynamically scheduling data transmission. To avoid overlapping of data transmissions for the same HARQ process number, the data previously using that HARQ process number should be retransmitted and combined as intended before the HARQ process number is used for the subsequent data transmission. The embodiment breaks the conventional means that the HARQ process number of data transmission on the periodically configured resource is determined by the time position of the resource. Under the condition that the resource is periodically configured for N data transmission occasions at one time, M (M is more than or equal to 1 and less than or equal to N) actual data transmissions exist, and the number of the actually occupied HARQ process is also M, so that compared with the number of the actually occupied HARQ process, the multiplexing complexity of the HARQ process numbers of the data transmission on the periodically configured resource and the dynamic scheduling data transmission is lower, and the efficiency is higher.
Preferably, the configuration information includes a maximum value of M. Therefore, the number of the HARQ processes and the number of the HARQ processes which are used most in one period of the configured resources can be determined as early as possible, and the HARQ processes and the number of the HARQ processes can be conveniently shared with the dynamic scheduling data transmission. Optionally, the resources of the transmission occasions of the M actual data transmissions are adjacent to each other in time.
In this embodiment, the HARQ process number of the j (j is greater than or equal to 1 and less than or equal to M) th actual data transmission is determined by j and the basic HARQ process number. In order to avoid different determination results of j values of data transmission by a sender and a receiver of data transmission, the j-th actual data transmission may include control information, where the control information is used to determine the j value. The data receiver can determine the value of j corresponding to the actual data transmission according to the control information, and further determine the HARQ process number of the data transmission.

An embodiment of the present application further provides a network-side device, where, using the method according to any of the embodiments of the present application, at least one module in the network-side device is configured to perform at least one of the following functions: determining the periodic configuration resources, and determining the M data transmission opportunities in the ith period; determining the HARQ process number of the M times of actual data transmission; sending the configuration information; receiving CG PUSCH identified by the HARQ process number; and sending the SPS PDSCH identified by the HARQ process number.
