Description

Technical Field

[0002] With the continuous development of wireless communication technology, in the new generation of communication technology, Extended Reality (XR) is a more important application scenario in wireless technology, and XR devices can periodically generate some data streams. For example, XR devices can generate 45 frames of related data streams per second. At the same time, XR devices have low latency requirements in most cases. Therefore, according to the characteristics of periodically generated data streams and low latency requirements, consider scheduling transport blocks (TB) based on semi-persistent scheduling (Semi-Persistent Scheduling, SPS).

[0003] In the related art, the supported SPS period is an integer multiple period, for example, the optional SPS period is {10ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, 160ms, 320ms, 640ms}. When scheduling TB based on an integer multiple SPS period, the time slot, starting symbol and symbol length of TB transmission in different SPS periods are the same. Therefore, the time slot, starting symbol and symbol length of the TB can be determined based on the Time Domain Resource Allocation (TDRA) table. Summary of the invention

[0091] Figure 1 is a diagram showing a communication system architecture of a network device and a terminal according to an exemplary embodiment. The communication method provided by the present disclosure can be applied to Figure 1 As shown in the communication system architecture diagram.

According to the capacity, rate, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called new radio network (New Radio, NR). For the convenience of description, the present disclosure sometimes refers to the wireless communication network as a network.

[0094] Furthermore, the network equipment involved in the present disclosure may also be referred to as a wireless access network device. The wireless access network device may be: a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP) or a transmission and reception point (TRP), etc. It may also be a gNB in ​​an NR system, or it may also be a component or part of a device constituting a base station. When it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device form adopted by the network device are not limited.

[0095] Furthermore, the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users.

It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0096] Among the new generation of communication technologies, XR and cloud gaming are important applications of 5G. In the research of related technologies, XR and cloud gaming include the following technologies:

[0097] Viewport-related streaming media (Virtual Reality1, VR1);

[0098] Split rendering: using time-folded device viewport rendering (Virtual Reality2, VR2);

[0099] XR distributed computing (Augmented Reality1, AR1);

[0100] XR dialogue (Augmented Reality2, AR2);

[0101] Cloud gaming (Computer Graphics, CG).

[0102] It should be noted that the XR device can be connected to the network through downlink (DL) / uplink (UL) direct communication.

[0103] In XR devices, some data streams can be generated periodically, for example, a relevant number of streams of 45 frames per second. Consider scheduling TBs based on SPS, in other words, consider candidate data streams that accommodate XR traffic in the SPS period. In addition, XR devices have low latency requirements in most cases.

[0104] In the related art, the supported SPS period is an integer multiple period, for example, the optional SPS period is {10ms, 20ms, 32ms, 40ms, 64ms, 80ms, 128ms, 160ms, 320ms, 640ms}. When scheduling TB based on an integer multiple SPS period, the time slot, starting symbol and symbol length of the TB transmission in different SPS periods are the same. Therefore, the symbol position of the TB can be determined based on the TDRA table, wherein the symbol position may include the time slot, starting symbol and symbol length of the TB. Among them, the index of the TDRA table is given by the Radio Resource Control (RRC) signaling / Downlink Control Information (DCI) signaling, and the time slot, starting symbol and symbol length of the TB are determined by the index of the TDRA table. The TDRA index given by the RRC signaling is used for the scheduling of type 1 configured grant (configured grant, CG) (type 1CG), and the TDRA index given by the DCI signaling is used for type 2CG and SPS (type2CG and SPS). Among them, CG is used for uplink data transmission and SPS is used for downlink data transmission.

[0105] However, the related art only supports the time domain resource allocation method under the semi-static scheduling mechanism of integer multiple periods of the SPS period. The disclosed embodiment proposes a method that can be applied to the scenario where the SPS period is a non-integer multiple period; in this scenario, the TB transmission start symbol position determined by the TDRA table may appear before the start symbol position of the non-integer multiple SPS period, which can realize the semi-static scheduling of non-integer multiple periods.

[0106] In the related technology of communication network, as mentioned above, the time slot, starting symbol and symbol length of TB can be determined by the index of TDRA table. And the time slot, starting symbol and symbol length of TB at different integer multiple SPS period transmission opportunities determined based on TDRA table are the same. Figure 2 is a schematic diagram of the relationship between non-integer multiple periods and time slots, such as Figure 2As shown, for non-integer multiples of the SPS period, the starting symbol of the TB determined by the TDRA table does not match the starting symbol of the non-integer multiples of the SPS period. In the figure, the K0 value indicates whether the physical downlink control channel (PDCCH) and the physical downlink shared channel (PDSCH) scheduled by it are scheduled in the same time slot or across time slots. Among them, the K0 value is the time slot difference between the time slot occupied by the PDCCH and the time slot occupied by the PDSCH scheduled by it. The value of K0 has a value set, which is configured to the terminal by the network device through RRC signaling, for example, it can be {0, 1, 2...}. If K0=0, it means that PDCCH and PDSCH are in the same time slot, that is, "same time slot scheduling". If K0>0, it means that PDCCH and PDSCH are not in the same time slot, that is, "across time slot scheduling". The network device can directly indicate the K0 value to the terminal, or the network device can configure a time domain resource allocation (TDRA) table for the terminal, where the TDRA table includes an index value (index) and the K0 value corresponding to the index value. The network device can indirectly indicate the K0 value to the terminal by indicating the index value to the terminal.

[0107] Based on this, the present disclosure provides a transmission method for scheduling TBs in non-integer multiple SPS periods, determining the starting symbol of TBs for transmitting TBs in non-integer multiple SPS periods, and solving the problem that the starting symbol of TBs determined by the TDRA table does not match the starting symbol of non-integer multiple SPS periods. It should be noted that all embodiments of the present disclosure can be applied to both network-side devices and terminal-side devices.

[0108] Figure 3 FIG. 1 is a flow chart showing a transmission method according to an exemplary embodiment. Figure 3 As shown, the transmission method is used in a terminal and includes the following steps.

[0109] In step S11 , in response to the period of scheduling the TB being a non-integer multiple of the semi-persistent scheduling period, a symbol position of the TB transmission is determined.

[0110] In the disclosed embodiment, when scheduling TB, the transmission opportunity of TB is included in different scheduling periods. In the services of some devices, data streams with non-integer multiple periodicity may appear, for example, a periodic data stream of 60 frames per second or 45 frames per second may be generated. Taking the case where a periodic data stream is generated at 60 frames per second and the semi-static scheduling period is an SPS period as an example, 1 / 60 seconds is an SPS period. At this time, a non-integer multiple period of milliseconds appears, that is, 16.67ms is an SPS period.

[0111] In response to the period of the scheduled TB being a non-integer multiple of the semi-static scheduling period (for example, 16.67 ms is a semi-static scheduling period), the symbol position of the TB transmitted within the period is determined. The symbol position may at least include the time slot where the TB is located, the start symbol of the TB, and the symbol length of the TB. It is understandable that the symbol length of each TB is the same.

[0112] In the transmission method disclosed in the present invention, a scheme is proposed to determine the symbol position of the scheduled TB transmission in the non-integer multiple semi-static scheduling period, which can avoid the problem of mismatch between the starting symbol of the scheduled TB and the starting symbol of the non-integer multiple semi-static scheduling period.

[0113] Figure 4 FIG. 1 is a flow chart showing a transmission method according to an exemplary embodiment. Figure 4 As shown, determining the symbol position of TB transmission includes the following steps.

[0114] In step S21, a first starting symbol is determined.

[0115] The first starting symbol is the starting position of the semi-persistent scheduling period. In all embodiments of the present disclosure, for ease of description, the position where the starting symbol of the semi-persistent scheduling period is located is referred to as the first starting symbol.

[0116] In step S22, a symbol position is determined according to the first starting symbol.

[0117] In an embodiment of the present disclosure, the starting position of each semi-static scheduling period is determined according to the starting position of the semi-static scheduling period. The symbol position of the TB transmission is determined according to the starting position of each semi-static scheduling period. The symbol position of the TB transmission includes the starting symbol position of the TB transmission. In all embodiments of the present disclosure, for ease of description, the starting symbol position of the TB transmission is referred to as the third starting symbol. It can be understood that the determined third starting symbol is after the first starting symbol, or the determined third starting symbol may coincide with the first starting symbol.

The transmission method of the embodiment of the present disclosure includes: determining the symbol position of TB transmission according to the first starting symbol of the semi-static scheduling period.

[0120] In step S31, a second start symbol is determined.

[0121] The second starting symbol is the location of the TB transmission preset starting symbol determined based on the TDRA table. In the embodiments of the present disclosure, for ease of description, the TB transmission preset starting symbol location determined based on the TDRA table is referred to as the second starting symbol. In some embodiments, the TDRA table can be any TDRA table in the related art.

[0122] In step S32, the symbol position is determined based on the sequence of the first starting symbol and the second starting symbol.

[0123] In the disclosed embodiment, the determined second start symbol is the same in each time slot, and thus the sequence of the first start symbol and the second start symbol is determined based on the comparison between the first start symbol of each cycle and the second start symbol in the time slot.

[0124] The embodiment of the present disclosure provides a transmission method, which can be implemented alone or together with any other embodiment of the present disclosure. The transmission method of the embodiment of the present disclosure includes: determining a symbol position based on the sequence of a first start symbol and a second start symbol.

In the embodiment of the present disclosure, the first time slot is the next adjacent time slot of the time slot where the TB is located.

[0139] In one embodiment, Fig. 9 As shown, the second starting symbol (i.e., the location of the preset starting symbol for TB transmission determined based on the TDRA table index) can be delayed to the location of the first starting symbol (i.e., the location of the starting symbol of the semi-static scheduling period), that is, the first starting symbol is used as the starting symbol of TB transmission (i.e., the third starting symbol). In one approach, the location n symbols away from the first starting symbol is used as the third starting symbol, in other words, the Nth symbol after the first starting symbol is determined as the starting symbol of TB transmission (i.e., the third starting symbol).

[0140] In any of the above embodiments, n can be determined based on at least one of the following methods:
