Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which an embodiment of the present invention is applicable, as shown in fig. 1, including a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: a terminal-side Device such as a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (wireless Device), a robot, a vehicle, etc., it should be noted that the specific type of the terminal is not limited in the embodiment of the present invention. The network side device 12 may be an access network device, such as a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, etc., or the network side device may be an Access Point (AP); the network side device may also be a Central Unit (CU); or the network side device may also be a core network device, for example: a mobility management entity (Mobility Management Entity, MME), an access mobility management function (Access Management Function, AMF), a session management function (Session Management Function, SMF), a user plane function (User Plane Function, UPF), a Serving GateWay (SGW), a PDN GateWay (PDN GateWay), a policy control function (Policy Control Function, PCF), a policy and charging rules function (Policy and Charging Rules Function, PCRF), a GPRS service support node (Serving GPRS Support Node, SGSN). It should be noted that, in the embodiment of the present invention, the specific type of the network side device is not limited.

Referring to fig. 2, fig. 2 is a flowchart of a transmission type determining method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

201. the network side equipment configures a transmission type of the 1 st transmission sent by the PDSCH in the time domain resource for the terminal;

202. the network side equipment determines the transmission type or transmission parameter of the Nth transmission sent by the PDSCH in the time domain resource according to the transmission type of the 1 st transmission;

The network side device may configure, for the terminal, a transmission type of the 1 st transmission sent by the PDSCH in the time domain resource through signaling.

The time resource may be a slot (slot) or other time resource comprising a plurality of symbols.

In the embodiment of the present invention, the number of transmission times of PDSCH in the time domain resource being greater than or equal to N may be understood that PDSCH has multiple transmission opportunities in the time domain resource. In addition, the nth transmission of the PDSCH in the time domain resource may also be understood as the nth transmission opportunity of the PDSCH in the time domain resource. Preferably, N is 2, and the number of transmissions of PDSCH in the time domain resource is 2. For example: the PDSCH is transmitted 2 times in a time slot, each time domain resource is associated with a TCI state (TCI state), and the time domain resources are not overlapped with each other, where a time domain resource refers to a group (only one time slot in each group) of sub-time slots (mini slots), so that the PDSCH can be transmitted in a time division multiplexing (Time Division Multiplexing, TDM) mode in the time slot.

The network side device determines, according to the transmission type of the 1 st transmission, the transmission type or the transmission parameter of the nth transmission sent by the PDSCH in the time domain resource, and may determine the transmission type or the transmission parameter of the nth transmission according to a correspondence between the transmission type of the 1 st transmission and the transmission type or the transmission parameter of the nth transmission.

In addition, in the embodiment of the present invention, the transmission type of the PDSCH may also be referred to as a mapping type (PDSCH mapping type) of the PDSCH.

In the embodiment of the invention, the transmission type or the transmission parameter of the nth transmission sent by the PDSCH in the time domain resource can be determined according to the transmission type of the 1 st transmission. In this way, when the nth transmission is performed, the network side device transmits according to the transmission type, and the terminal receives according to the transmission type, so that the transmission performance of the PDSCH can be improved.

Furthermore, as the PDSCH transmission is multiplexed in the time resource, the PDSCH transmission type is clarified, thus the problem of complexity increase of the receiver caused by different relative positions of the DMRS in the transmission time is avoided, the problem of ambiguity of TBS determination caused by different numbers of the DMRS in the transmission time is avoided, and the consistency of understanding of network side equipment and terminals in the scheme is ensured.

In addition, in the embodiment of the present invention, the PDSCH may be a low latency highly Reliable (URLLC) PDSCH, which is not limited, and may be a service PDSCH.

As an optional implementation manner, the determining, by the network side device, a transmission type or a transmission parameter of an nth transmission sent by the PDSCH in the time domain resource according to the transmission type of the 1 st transmission includes:

It should be noted that, a plurality of transmission types are agreed in the protocol, where the transmission type B is one of the transmission types agreed in the protocol, and may further include a transmission type a, and transmission parameters of each transmission type are defined in the protocol, for example, a relative position of DMRS of each transmission type on a scheduled time domain resource and/or the number of DMRS are defined.

Transmission type a and transmission type B are illustrated below by tables 1 and 2:

table 1: DM-RS PDSCH DM-RS position of single preamble symbol

Table 2: DM-RS PDSCH DM-RS position of 2 preamble symbols

The pre-DMRS symbol represents a first/group DMRS symbol, the location indication in the scheduling area according to the different PDSCH transmission types may be shown in table 1 and table 2, pos0 is a first DMRS symbol location, pos1 is a second DMRS symbol location if there are other DMRS symbols, and at most 3 other DMRS symbols/group may be configured. l (L) ₀ The symbol representing the occupation of the DMRS is the position, l _d Indicating additional DMRS positions.

It should be noted that, the above tables 1 and 2 are only examples of the transmission type a and the transmission type B, and in the embodiment of the present invention, the transmission type a and the transmission type B are not limited, and may specifically be referred to as transmission type a and transmission type B that are already defined in the protocol, or may be newly defined in the subsequent protocol version.

In this embodiment, if the transmission type a of the transmission type of the 1 st transmission of the PDSCH in the time domain resource is determined, the transmission type B of the transmission type of the nth transmission of the PDSCH in the time domain resource is directly determined.

When the PDSCH scheduling length is 4, the time domain resource allocation in this embodiment may be l as shown in fig. 3 ₀ For example, =2, the preamble symbol (FL) =1, when the data schedule occupies a control resource set (control resource set, core) symbol, i.e. when the PDSCH schedule is earlier than the first DMRS symbol, as shown in the first transmission in the first two configurations shown in fig. 3, the DMRS position is different from the DMRS relative position in the respective transmission for the second transmission; when data scheduling is from the first DMRS symbolInitially, the relative positions of DMRS in both transmissions are the same. Wherein K0 represents a space K0 symbols between the first transmission occasion and the second transmission occasion.

When the PDSCH scheduling length is 7, a single preamble DMRS symbol is taken as an example, and a schematic of resource allocation in this embodiment is shown in fig. 4.

the relative position of the DMRS on the scheduling time domain resource corresponding to the Nth transmission and the number of the DMRS.

Thus, the relative position of the DMRS on the scheduling time domain resource corresponding to the Nth transmission is the same as the relative position of the DMRS on the scheduling time domain resource corresponding to the 1 st transmission, and the number of the DMRS of the Nth transmission is the same as the number of the DMRS of the 1 st transmission.

The time domain resource allocation in this embodiment is shown in fig. 5 below, where l is ₀ For example, =2.

In the above embodiment, if the transmission type B of the transmission type of the 1 st transmission transmitted by the PDSCH in the time domain resource is determined, the transmission type B of the transmission type of the nth transmission of the PDSCH in the time domain resource may be directly determined.

As an alternative embodiment, the 1 st transmission and the nth transmission correspond to the same TBS.

The TBS of the 1 st transmission and the nth transmission may be determined according to the resources allocated by the nth transmission; or alternatively

The TBS of the 1 st transmission and the nth transmission may be determined according to the resources allocated for the 1 st transmission.

In this embodiment, the TBS that can be transmitted is calculated according to the resources allocated for the nth transmission (i.e., the nth transmission opportunity), and the TBS is applied to the first transmission (i.e., the first transmission opportunity) at the same time. Or the transmitted TBS is calculated according to the resources allocated by the first transmission opportunity, and the TBS is simultaneously applied to the Nth transmission opportunity.

Because the corresponding same TBS of the 1 st transmission and the N th transmission, ambiguity generated by estimating the TBS according to the corresponding different transmission by different TRPs is avoided, and errors caused by inconsistent understanding of network side equipment and terminals are avoided, so that the effect of improving the PDSCH transmission performance is achieved.

In this embodiment, the method may be applied to a case where the pre-DMRS symbol is configured as a single symbol, and the scheduling length may be 7 symbols, which is not limited, and may also be applied to other scenarios or other scheduling lengths, such as 4 symbols.

Further, in the case that TBSs of the 1 st transmission and the nth transmission are determined according to the resources allocated for the 1 st transmission:

And if the code rate of the TBS used in the Nth transmission is larger than a preset threshold, the network side equipment does not carry out the Nth transmission.

Of course, in this case, if the code rate of using the TBS in the nth transmission is greater than a preset threshold, the terminal may not perform the reception corresponding to the nth transmission.

The terminal not receiving the corresponding nth transmission may mean that the terminal does not receive at a transmission timing of the nth transmission.

The preset threshold may be agreed or configured by the network side, for example: 0.95 or 0.9, etc. For example: the TBS needs a second transmission opportunity to determine whether the actual code rate is effective, and if the code rate is greater than 0.95, the transmission and the reception of the second transmission opportunity are not performed.

Therefore, the situation that transmission is invalid due to unsuccessful decoding caused by the fact that the code rate of the TBS used in the Nth transmission is larger than a preset threshold value can be avoided, and transmission resources are saved.

Optionally, the DMRS mapping pattern of the nth transmission is the same as the DMRS mapping pattern of the 1 st transmission.

The DMRS mapping pattern of the nth transmission is the same as the DMRS mapping pattern of the 1 st transmission, and the network side device and the terminal modify the DMRS mapping pattern actually transmitted at the same time and the DMRS mapping pattern of the first transmission, so that ambiguity generated by estimating TBS by different TRPs according to corresponding different transmissions can be avoided, errors caused by inconsistent understanding of the network side device and the terminal can be avoided, and the effect of improving PDSCH transmission performance can be achieved.

As an optional implementation manner, the configuring, by the network side device, a transmission type of the 1 st transmission sent by the physical downlink shared channel PDSCH in the time domain resource for the terminal includes:

The scheduling length may refer to a scheduling length of the PDSCH in one transmission, and the scheduling length of each transmission in the time resource is the same. In addition, the scheduling length may include lengths of PDSCH and DMRS.

The scheduling length may be configured to the terminal by the network side, or the terminal requests from the network side device.

In this embodiment, it is possible to realize a transmission type for configuring the 1 st transmission transmitted by the PDSCH in the time domain resource only when the scheduling length of the PDSCH is the first length.

And the network side device determines the transmission type or transmission parameter of the nth transmission sent by the PDSCH in the time domain resource according to the transmission type of the 1 st transmission, including:

and under the condition that the scheduling length is the first length, the network side equipment determines the transmission type or the transmission parameter of the Nth transmission sent by the PDSCH in the time domain resource according to the transmission type of the 1 st transmission.

Optionally, the method further comprises:

wherein the first length is greater than the second length.

For example: the first length is 3, 4, 5 or 7 symbols.

In the above embodiment, when the scheduling length is the second length, the transmission type B of the transmission type of the nth transmission sent by the PDSCH in the time domain resource may be directly determined.

Further, in the case that the scheduling length of the network side device is the second length, the type of the 1 st transmission may be agreed by a protocol or preconfigured by the network side, which is not limited.

As an optional implementation manner, TCI states corresponding to different transmissions of the PDSCH in the time domain resource are different.

And/or

The TCI states corresponding to the PDSCH in the time domain resources may be different from the TCI states corresponding to the PDSCH in the time domain resources in different transmission occasions.

The transmission of the PDSCH in the time domain resource may be coordinated multipoint transmission based on the network side device, where the different transmission times of the PDSCH in the time resource are different transmission times of coordinated multipoint transmission of the network side device, such as transmission of different TRPs.
