Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

The technical solutions provided by various embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

The application scenario of this application is for data information between a network side device (gNB) and a terminal side device in a wireless communication system.

FIG. 1 is a schematic diagram of data transmission opportunities configured in one cycle of the CG PUSCH. CG PUSCH scheduling allocates PUSCH resources to a specific UE periodically. There are two ways to transmit CG PUSCH configuration: one is CG PUSCH type 1, and the resources for transmission authorization are provided by RRC. UE stores this configuration and uses it as authorized configuration when there is uplink data transmission. The other is CG PUSCH type 2. The RRC layer configures information such as the cycle of the CG PUSCH, the HARQ sequence number, and then the physical downlink control channel PDCCH activates or deactivates the configuration. The PDCCH for activating or deactivating the CG PUSCH includes resources occupied by the PUSCH in time and frequency, and the time position of the first CG PUSCH. After obtaining the activation information, the UE can use the CG PUSCH resource. Figure 1 is a schematic diagram of CG PUSCH type 2. After acquiring the PDCCH that activates the CGPUSCH, the UE periodically occupies the CG PUSCH resource to send uplink information.

FIG. 2 is a schematic diagram of configuring multiple data transmission opportunities in one cycle of the CG PUSCH. The packet arrival of the Extended Reality (XR for short) service is periodic, but the actual arrival time of the packet may experience jitter, resulting in random arrival within the jitter time window. Figure 2 is an example, in this example, the first jitter time window starts at time t0, where an XR data packet can arrive within this time window between t0 and t3, and the XR data packet arrives at time t1 in the figure. The next XR data packet arrives after time P, and the arrival time of the next XR data packet can arrive at any time within the jitter time window between t4 and t7. The next XR data packet in the figure arrives at time t7. In order to meet the characteristic of XR service arrival time jitter, multiple data transmission opportunities can be configured in one cycle P of CG PUSCH to meet the requirement that service packets can be sent in time after they arrive.

Fig. 3 is a schematic diagram of sending actual data at multiple data transmission opportunities in a CG PUSCH cycle.

Additionally, XR's packet size varies over time. Taking AR/VR 30Mbps as an example, the maximum packet size is 93750 bytes, and the minimum packet size is 31250 bytes. On the basis that one CG PUSCH cycle includes multiple PUSCH transmission opportunities, the number of PUSCHs occupied by data packets is determined by the size of the data packets. As shown in Fig. 3, in the first period of the CG PUSCH, the XR data packet occupies 3 PUSCHs to transmit TB1, TB2, and TB3 respectively. In the next CG PUSCH period, the XR data packet occupies one PUSCH to transmit TB4.

FIG. 4 is an indication of resource occupancy of multiple transmission opportunities in one cycle of the CG PUSCH. CG PUSCH-related occupancy indication, when multiple CG PUSCH transmission opportunities are configured in each CG period, since the semi-statically configured CG resources cannot match the dynamic frame size well, the CG resources in the CG period may be over-allocated to avoid Delays due to frequent requests for additional resources. In order to improve resource utilization, it may be considered that the gNB dynamically reclaims the CG PUSCH resources not used by the UE, and allocates these resources to other UEs. As shown in FIG. 4 , there are four transmission opportunities in one cycle of the CG PUSCH resource configured for the UE. According to the resources actually occupied by the XR data in each cycle, the UE can send an "occupancy indication" of its usage of these resources to the gNB. For unused resources, gNB can allocate them to other UEs to improve the utilization efficiency of uplink resources.

In this application, the time position of the CG PUSCH resource configured for UE1 is called "CG PUSCH transmission opportunity", and if there is any type of UL-SCH, CSI, and CSI on the CG PUSCH resource, it is called "CG PUSCH transmission opportunity". " with actual data. The UL-SCH transmitted on the CG PUSCH resource is called the first type of actual data, the CSI transmitted on the CG PUSCH resource is called the second type of actual data, and the SRS transmitted on the CG PUSCH resource is called the third type of actual data.

Fig. 5 is a schematic diagram of the function of resource occupancy indication on the CG PUSCH. Considering that random data generated by the application layer may cause traffic changes, the demand for transmitting the actual PUSCH on the CG PUSCH is bursty. As shown in FIG. 5 for the CG PUSCH configuration, there are 12 CG PUSCH transmission opportunities in each period. In the first period, the actual CG PUSCH occurs at T1-5, T1-6, T1-7, and T1-9. In the second period, the actual CG PUSCH occurs at T2-3, T2-4, T2-5, T2-9, T2-10. In the first period, there is the last CG PUSCH transmission opportunity T1-9 of the actual PUSCH, and UE1 does not predict that it does not need to occupy the CG PUSCH resources on T2-1 and T2-2. Although the CG PUSCH resources on T2-1 and T2-2 are not occupied by UE1, they cannot be reclaimed and re-allocated by the gNB. On the other hand, it takes a period of time from the gNB to obtain the "occupancy indication" sent by the UE to the gNB scheduling the unused CGPUSCH resources of the UE to other UEs, which means that the resources indicated by the "occupancy indication" that can be reallocated by the gNB also lag behind Where the Occupancy Indication message is sent. For example, in Figure 5, UE1 can send an "Occupancy Indication" at T1-5, indicating that the CG PUSCH resources on T1-6 are not occupied. It will take some time for gNB to allocate the CG-PUSCH on T1-6 to other UEs after obtaining this indication. , it is possible that the gNB does not have time to allocate the resource to other UEs. According to the prior art, the "occupancy indication" information can only be carried when there is actual data, which affects the timeliness and system efficiency of the "occupancy indication".

Fig. 6 is a flowchart of an embodiment of the method of the present application.

This application proposes a method for transmitting control information, including the following steps 110-130:

Step 110, determine the transmission timing of the configured CG PUSCH;

Preferably, the following steps are further included: determining a time set, the time set is a subset of all transmission opportunities of the configured CG PUSCH, and the occupation indication is used to indicate whether there is actual data at a certain transmission opportunity in the time set.

Step 120, among the multiple transmission opportunities, determine the idle time unit without actual data; the actual data includes any combination of UL-SCH, SCI and SRS;

Step 130: Determine the second resource used to transmit the occupancy indication, the second resource is a subset of the first resource, the first resource is the CG PUSCH resource located in the idle time unit, and the occupancy indication is used Indicates whether there is actual data on one or more of the transmission opportunities.

Preferably, the following step is further included: defining the second resource in the first resource by setting coefficients.

Preferably, the setting coefficients include at least one of the following:

The first coefficient is used to determine the second resource according to the quantity of the occupation indication information and a first set coefficient;

The second coefficient is used to determine the second resource according to the first resource and the second set coefficient.

Preferably, the method further includes a step of: determining through the identification information that what is transmitted at the transmission opportunity is actual data and/or an occupation indication.

Preferably, the identification information includes at least one of the following:

The first identifier is used to indicate that there is no actual data and there is an occupation indication within the transmission opportunity;

The second identifier is used to indicate that there is actual data in the transmission opportunity and there is no occupation indication;

The third identifier is used to indicate that there are actual data and occupation indications in the transmission opportunity.

It should be noted that the above steps are used for network entities of the wireless communication system, including terminal-side equipment, network-side equipment, or other intermediate equipment; the above steps can also be used for providing information processing service devices for the network entity equipment; the above steps also It can be used in any device, system, subsystem, circuit, chip or software entity that provides information reception, transmission, identification, and processing for terminal-side equipment or network-side equipment.

The inventive idea of the present application is to allow the terminal device to send "occupancy indication" on some or all of the allocated resources at the transmission opportunity of the CG PUSCH when there is no actual data at the transmission opportunity of the CG PUSCH, which can improve the efficiency of CGPUSCH resource recovery, Improve system resource usage efficiency. Correspondingly, the transmission and reception detection of the terminal device side and the gNB side at the transmission opportunity of CG PUSCH has the following optimizations:

The terminal side device: within the time set, send an "occupancy indication" at the configured CG PUSCH transmission timing, where there is no actual data at the CG PUSCH transmission timing, and the first resource is configured at the CG PUSCH transmission timing, and send The "occupancy indication" uses the second resource, which belongs to the first resource. Optionally, the time set is a subset of configured CGPUSCH transmission opportunities.

Network side device: within the time set, at the configured CG PUSCH transmission opportunity, the gNB blindly detects the following two situations:

Actual data is detected on the first resource, and the actual data includes any combination of UL-SCH, CSI, and SRS.

Control information is detected in a preset manner on the second resource, and the control information includes "occupancy indication".

When the first resource has no actual data, all of the first resources are used to upload the occupation indication, and the base station needs to use identification information to identify whether the information in the transmission opportunity is an occupation indication or actual data. Therefore, for example, if the first If the resource is the same as the second resource, it is determined through the identification information whether actual data, "occupancy indication" or actual data and "occupancy indication" are transmitted at the transmission opportunity;

If the second resource is a part of the first resource, in addition to the identification information, the base station may also determine whether to include the occupation indication by detecting whether there is information on some resources or all resources in the transmission opportunity. Therefore, for another example, if the first resource and the second resource are different, the second resource is determined through the first coefficient and the number of "occupancy indications"; or the gNB indicates the second resource through the first coefficient and the second coefficient.

It should be noted that the CG PUSCH scheduling periodically allocates PUSCH resources to a specific UE. There are two types of resources configured by CGPUSCH: one is CG PUSCH type 1, and the resources for transmission authorization are provided by RRC. The UE stores the configuration and uses it as an authorization configuration when there is uplink data transmission. The other is CG PUSCH type 2. The RRC layer configures information such as the cycle of the CG PUSCH, the HARQ sequence number, and then the physical downlink control channel PDCCH activates or deactivates the configuration.

The CG PUSCH resource satisfies periodicity. Taking the cycle as P as an example, in order to meet the transmission requirements of service data arrival time jitter and/or service data volume fluctuations, a cycle time includes N≥2 transmission opportunities. Since in a cycle P of CG PUSCH, the transmission timing of the actual data transmission start is uncertain, whether the data transmission is repeated data transmission is uncertain, and the number of transmission opportunities occupied by data transmission is uncertain, in order to satisfy the data For transmission requirements, the amount of CG PUSCH resources configured by the gNB for the UE is often greater than the amount of data transmission of the UE. In this way, some CG PUSCH resources have actual data transmission requirements, and some CG PUSCH resources have no actual data transmission requirements. The actual data here refers to any combination of UL-SCH, CSI and SRS. Considering that random data generated by the application layer may cause traffic changes, the demand for transmitting actual data on CGPUSCH is bursty. On the other hand, it takes a period of time from when the gNB obtains the "occupancy indication" sent by the UE to when the gNB schedules the CG PUSCH resources not used by the UE to other UEs. Therefore, after the UE determines that there is no actual data on a certain transmission opportunity, the sooner the UE sends the "Occupancy Indication", the more the gNB can coordinate the scheduling of the UE's resource release and improve the overall resource efficiency of the system. According to the method described in this application, the UE is allowed to transmit "occupancy indication" information when there is no actual data on the configured CG PUSCH transmission opportunity, which is used to determine whether there is any on the at least one configured CG PUSCH transmission opportunity The timing data can make the time for gNB to obtain the "occupancy indication" information not be affected by whether there is actual data, improve the efficiency of gNB in coordinating the scheduling of the UE's resource release, and improve the overall resource efficiency of the system.

On the other hand, if the UE has no actual data at the CG PUSCH transmission opportunity, some or all of the configured resources at the CGPUSCH transmission opportunity can send "occupancy indication", then the UE's configuration resource transmission at the CG PUSCH transmission opportunity There are several situations for the data: the first one is that the UE sends actual data at the resource of the CG PUSCH transmission opportunity, but does not send the "occupancy indication". The second is that the UE sends actual data and "occupancy indication" at the resource of the CG PUSCH transmission opportunity. The third is that the UE does not send actual data at the resource of the CG PUSCH transmission opportunity, but sends an "occupancy indication". The fourth is that the UE does not send anything at the resource of the CG PUSCH transmission opportunity. The gNB does not know in advance whether the UE sends information on the configured resource of the CG PUSCH transmission opportunity, and what information to send. The gNB will have to determine the UE's transmission on the configured resources of the CGPUSCH transmission occasion by detection. In order to detect different situations in which the UE transmits information on the configured CG PUSCH, the gNB may determine by detecting the reference information on the configured CG PUSCH transmission timing. On the UE side, if the "occupancy indication" is sent on the second resource, the first identifier is used. In the idle time unit, if there is actual data (and no occupancy indication) on the configured CG PUSCH transmission opportunity, the second identifier is used. If the configured CG PUSCH transmission opportunity has actual data and an "occupancy indication", the third identifier is used. It can be seen that the first identifier, the second identifier, the third identifier, etc. are used to identify whether the UE sends data on the CG PUSCH, and the format and content of the sent data are different. Preferably, the first identifier, the second identifier, and the third identifier may be demodulation reference signals of CG PUSCH transmission information. UE and gNB preset the corresponding relationship between different reference signals and CG PUSCH transmission information. Correspondingly, for the third case in which the UE transmits data at the configured resource of the CG PUSCH transmission opportunity, the gNB needs to use the first method to detect the resources of the CG PUSCH transmission opportunity. Specifically, it means that the gNB detects whether the first identifier is received, and if it detects that the first identifier is received, it confirms that the UE has sent control information on the second resource, and the control information includes the "occupancy indication". If it is not detected that the first identifier is received, it is confirmed that the UE sends the control information including the "occupancy indication" without the second resource. The "occupancy indication" is used to determine whether there is actual data on the transmission opportunity of the at least one configured CG PUSCH. There is no actual data at the transmission opportunity of the CGPUSCH in the idle time unit, and the actual data includes any combination of UL-SCH, CSI and SRS.

Further, for the first case where the UE transmits data at the configured resource of the CG PUSCH transmission opportunity, the gNB may use a second method to detect the resources of the CG PUSCH transmission opportunity, and the second method refers to whether the gNB detects whether After receiving the second identifier, if the second identifier is detected, it is confirmed that the UE has sent actual data on the first resource, and if the second identifier is not detected, it is confirmed that the UE has not sent actual data on the first resource. For the second case where the UE transmits data on the configured resource of the CG PUSCH transmission opportunity, the gNB determines the situation that the UE transmits on the resource by detecting the reference information on the configured CG PUSCH transmission opportunity.

Further, for the second case where the UE transmits data on the resources configured at the CG PUSCH transmission opportunity, the gNB may use a third method to detect the resource at the CG PUSCH transmission opportunity, and the third method refers to the gNB detecting Whether the third identifier is received, and if the third identifier is detected, it is confirmed that the UE has sent actual data and an occupation indication on the first resource.

Due to the support of UE's new transmission situation on CG PUSCH configuration resources, the reception and processing complexity of gNB is increased. In order to reduce the processing load of the gNB, it can be restricted that if the UE does not have actual data at the transmission timing of the CG PUSCH, the situation that the UE sends the "occupancy indication" at the transmission timing of the CGPUSCH only occurs at some transmission timings of the CG PUSCH. The gNB may send the configuration information to the UE, which is used for the UE to determine at which transmission opportunities the "occupancy indication" can be sent without actual data, and these transmission opportunities are referred to as reference transmission opportunities. In this way, the gNB can detect this situation only at the reference transmission occasion. For example, the idle time unit belongs to the reference transmission opportunity, and the gNB detects the resources of the CG PUSCH transmission opportunity in the idle time unit in the first way. The first way is to detect control information on the second resource, where the control information includes "occupancy indication". The "occupancy indication" is used to determine whether there is actual data on at least one configured CG PUSCH transmission opportunity. Except for the reference transmission opportunity, the gNB does not need resources for detecting the transmission opportunity of the CG PUSCH according to the first manner.

The resource at the transmission opportunity of the CG PUSCH is configured to meet the data transmission requirement of the UE. If there is no actual data, it is possible that resources are excessive when occupying these resources and sending "occupancy indications".

Fig. 7 is a schematic diagram of a first resource and a second resource. The CG PUSCH resource located in the idle time unit is the first resource, and then an "occupancy indication" is sent on the second resource, where the second resource is a subset of the first resource. Optionally, the second resource is the same as the first resource.

One possible manner is that the gNB sends the first coefficient, and determines the second resource according to the first coefficient and the information amount of the "occupancy indication". Assuming that the value of the first coefficient is β, and the information volume of the "occupancy indication" is P, the number of reference resource units is determined by β, Q, and the modulation mode Q _m and coding rate R configured by CG PUSCH. Then determine the number of reference resource units L represents ##, and the second resource is a resource block whose number of resource units is not less than zero in a preset position in the first resource. A resource block consists of several resource units and is the basic unit of uplink information transmission resources. For example, the second resource is J resource blocks with the lowest frequency in the first resource, the J resource blocks contain no less than zero resource units, and the J-1 resource blocks contain less than zero resource units. Similarly, the second resource may be the J resource blocks with the highest frequency in the first resource.

Another way is that the gNB sends the second coefficient, and the second resource is determined according to the first resource and the second coefficient. Assume that the second resource coefficient takes a value of γ, and the first resource includes K resource blocks. The second resource is the J resource blocks with the lowest frequency in the first resource, where Similarly, the second resource may be the J resource blocks with the highest frequency in the first resource.

Furthermore, if the simultaneous transmission of PUSCH and PUCCH occupies widely separated frequency resources, serious intermodulation products will be generated. Therefore PUSCH and PUCCH are usually not sent at overlapping times. When the PUSCH and the PUCCH overlap in time, the PUCCH is discarded, and the control information in the PUCCH is carried and sent on the PUSCH. If it is not supported for the terminal device to send the "occupancy indication" on the CG PUSCH resource when there is no actual data at the transmission timing of the CGPUSCH, the PUCCH at the overlapping time can be sent normally. However, if it is supported to send the "occupancy indication" on the CG PUSCH resource, it is necessary to discard the PUCCH at the overlapping time, and send the control information in it also on the CG PUSCH resource. That is, if there is an original PUCCH in the idle time unit, the UE discards the original PUCCH, and sends basic control information corresponding to the original PUCCH on the second resource.
