Description

Method and device for determining resource allocation

The present application claims priority from a chinese patent application filed on 12/7/2019 under the name of "method and apparatus for determining resource allocation", with the application number 201910630998.6, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of communications, and more particularly, to a method and apparatus for determining resource allocation.

Background

Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with explosive mobile data traffic increase, massive mobile communication device connection, and various new services and application scenarios which are continuously emerging, the fifth generation (5G) mobile communication system is in operation. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc). For example, URLLC technology has a high demand for reliability. In order to improve reliability, a common method is to utilize diversity gain of a channel, where the diversity gain includes diversity of the channel in at least one dimension of time domain, frequency domain, space domain, and the like.

One example of the spatial diversity gain of the channel is the independent channel diversity gain of multiple stations. There may be multiple base stations in the network, and multiple base stations may perform cooperative transmission therebetween. In the multi-station cooperation technology, the terminal device may be scheduled by multiple base stations, for example, the multiple base stations schedule the terminal device to receive multiple data. In the multi-station cooperation technology, the multi-station repeated transmission in a time domain is supported, and the robustness of the transmission is improved by utilizing the irrelevance of a channel in the time.

Currently, in the prior art, a Downlink Control Information (DCI) is used to indicate a symbol Offset1 in a slot to dynamically indicate an Offset between a last symbol of a first segment repetition and a first symbol of a second segment repetition in a slot, so as to determine a time domain resource allocation condition in a slot. However, this approach presents problems: DCI overhead is increased. Therefore, it is desirable to provide a solution to this problem.

In the embodiments of the present application, unless otherwise specified or conflicting with respect to logic, the terms and/or descriptions in different embodiments have consistency and may be mutually cited, and technical features in different embodiments may be combined to form a new embodiment according to their inherent logic relationship.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a global system for mobile communications (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolution (LTE) system, a LTE Frequency Division Duplex (FDD) system, a LTE Time Division Duplex (TDD), a universal mobile telecommunications system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a fifth generation (5G) or new radio system (NR 2X), etc. Alternatively, the V2X system may be embodied as any of the following systems: vehicle-to-internet (V2N), vehicle-to-vehicle (V2V), vehicle-to-vehicle (V2P), and vehicle-to-infrastructure (V2I), among others.

Hereinafter, some terms in the present application are explained to facilitate understanding by those skilled in the art.

1) A terminal device, also called a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device for providing voice/data connectivity to a user, for example, a handheld device with a wireless connection function, a vehicle-mounted device, etc. Currently, some examples of terminals are: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote medical (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), a vehicle networking (vehicle to intelligent, V2X) device, a vehicle-mounted communication chip, and the like.

2) A network device is a device in a wireless network, such as a Radio Access Network (RAN) node that accesses a terminal to the wireless network. Currently, some examples of RAN nodes are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc. In one network configuration, a network device may include a Centralized Unit (CU) node, or a Distributed Unit (DU) node, or a RAN device including a CU node and a DU node.

Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as RRC layer signaling or PHCP layer signaling, may also be considered to be transmitted by the DU or by the DU + RU under this architecture. It is to be understood that the network device may be a CU node, or a DU node, or a device including a CU node and a DU node. In addition, the CU may be divided into network devices in the access network RAN, or may be divided into network devices in the core network CN, which is not limited herein.

Fig. 1 is a schematic diagram of an application scenario of multi-site transmission to which an embodiment of the present application is applied. As shown in fig. 1, terminal device 110 is overlaid by a plurality of network devices 120. Terminal device 110 may communicate with network device 120. Terminal device 110 may be scheduled by multiple network devices 120. Terminal device 110 may receive data transmitted by multiple network devices 120 or may transmit data to multiple network devices 120.

The terminal equipment performs multi-station repeated transmission in a time domain, and improves the robustness of transmission by utilizing the incoherence of a channel in time. The transmission direction is not limited here, and may be uplink transmission or downlink transmission. "transmitting" includes "receiving" and "sending".

Fig. 2 is another exemplary diagram of a system architecture to which embodiments of the present application are applied. As shown in fig. 2, the communication system includes: V2X application server (application server), V2X devices (including V2X device 1 and V2X device 2), and network devices. The V2X devices communicate with each other through a PC5 interface. The communication link between V2X devices is defined as a Sidelink (SL). The communication between the V2X device and the V2X application server needs to be forwarded through the network device, specifically: for uplink, the sending end V2X device sends the V2X data to the network device through the Uu interface, and the network device sends the data to the V2X application server for processing, and then the V2X application server sends the data to the receiving end V2X device; for downstream, the V2X application server sends V2X data to the network device, which sends V2X data to the V2X device over the Uu interface.

It should be understood that the V2X device in fig. 2 is an example of a terminal device. It should be further understood that the flow direction of the arrow in fig. 2 is only exemplarily described with the V2X device 1, and is not limited to the embodiment of the present application, and in fact, the communication between the V2X device 1 and the V2X device 2 may be bidirectional, and the V2X device 2 may also perform uplink communication with the network device, which is not particularly limited.

The following receives a term or concept related to an embodiment of the application.

The time domain unit may include a subframe, a slot (slot), a mini-slot (mini-slot), a symbol, and the like. The minislot is a time domain unit with a time domain length smaller than the time slot. Wherein, one time slot may include 14 time domain symbols, and one micro time slot includes less than 14 time domain symbols, such as 2,4,7, and so on; or, a time slot may include 7 time domain symbols, and the number of time domain symbols included in a micro time slot is less than 7, such as 2 or 4, and the specific value is not limited.

The data transmission unit included in the time domain unit refers to a unit for transmitting data (e.g., downlink data or uplink data), for example, a Physical Downlink Shared Channel (PDSCH) for transmitting PDSCH. One or more data transmission units may be included in the time domain unit. For example, the time domain unit is a slot, and accordingly, each data transmission unit in the slot may be composed of one or more symbols in the slot.

At present, in an indication method for time domain resource allocation of time domain repeated transmission, taking a slot as an example, a network device may dynamically indicate a time domain offset, such as a symbol offset, for a terminal device through Downlink Control Information (DCI), where the symbol offset is used to indicate an offset between a last symbol of a time domain resource for transmitting data in a first segment of the slot and a first symbol of a time domain resource for transmitting data in a second segment of the slot. And the terminal equipment obtains time domain resource allocation in one slot based on the symbol offset, the initial symbol position S, the symbol length L and the number of times of repeatedly transmitting data in the slot. Describing with the example in fig. 3, it is assumed that the network device configures [ S, L ] ═ 1,2] through DCI, configures an offset O1 ═ 3, and configures a number of repeated transmissions K1 within one slot to 2 through Radio Resource Control (RRC). Correspondingly, the terminal device may obtain resource allocation as shown in fig. 3 based on S, L, K1, O1. As known from K1 ═ 2, the slot includes two segments of time domain resources for repeatedly transmitting data. In fig. 3, the first segment transmits data with time domain resources occupying symbol 1 and symbol 2, the symbol 1 and symbol 2 are referred to as a data transmission unit, and the second segment transmits data with time domain resources occupying symbol 6 and symbol 7, the symbol 6 and symbol 7 are referred to as a data transmission unit. The interval between the time domain resource of the first section for transmitting data and the time domain resource of the second end for transmitting data is 3 symbols. The number of times of repeated transmission is 2, and the slot includes two sections of time domain resources for transmitting data.

The inventors of the present application found that this approach requires an offset O1 to be added to the DCI, thereby increasing DCI overhead. In order to avoid this problem, the embodiment of the present application provides a method for determining resource allocation, which can determine a time domain resource location of repeated transmission in a slot without increasing DCI overhead.

Fig. 4 shows a schematic flow chart of a method 400 of determining resource allocation according to an embodiment of the application. As shown in fig. 4, the method 400 includes:

s410, the terminal device determines a first transmission frequency according to the first preset relationship, the initial position of the time domain resource and the duration length of the time domain resource, wherein the first transmission frequency refers to the frequency of repeatedly transmitting data in the time domain unit.

Exemplarily, taking the time domain unit as a slot as an example, the start position of the time domain resource may be a time domain start symbol, and the duration of the time domain resource may be a symbol length.

The terminal device may calculate a start position of the time domain resource and a duration length of the time domain resource according to a Start and Length Indicator Value (SLIV). Optionally, before S410, the method 400 further includes: the terminal equipment receives DCI from the network equipment, wherein the DCI is used for indicating the starting and length values of the time domain resource, such as a starting and length indication value SLIV domain; and the terminal equipment determines the starting position of the time domain resource and the continuous length of the time domain resource according to the starting and length values.

For example, taking the starting position of the time domain resource as the starting symbol position S and the duration length of the time domain resource as L as an example, the network device may indicate the time domain resource allocation for repeated transmission, for example, the SLIV domain, in the DCI during dynamic scheduling. The terminal device may calculate the starting symbol positions S and L from the SLIV domain. Alternatively, the network device may also send the starting symbol positions S and L directly to the terminal device.

Alternatively, the first preset relationship may be a predefined table. The terminal device may obtain the first transmission times by looking up a table. Alternatively, the first preset relationship may be a predefined formula. And the terminal equipment calculates the first transmission times through the formula. For example, the first number of transmissions may be denoted as K1.

S420, the terminal device determines the time domain position of at least one data transmission unit in the first time domain unit according to the first transmission times.

The first transmission number refers to the number of times data is repeatedly transmitted in one time domain unit. Here, the number of times data is repeatedly transmitted in the time domain unit is the same as the number of data transmission units. Here, the terminal device may obtain the number of data transmission units in the first time domain unit based on the first transmission times.

The at least one data transmission unit may be understood as one or more data transmission units. One data transmission unit is: and transmitting the time domain resource occupied by the physical downlink channel. For example, one data transmission unit may be a time domain resource occupied by transmitting the same physical downlink PDSCH. The same PDSCH may be repeatedly transmitted multiple times, occupying one data transmission unit each time. In addition, the same PDSCH may be from the same TRP or from different TRPs, and the same PDSCH from different TRPs is distinguished by different tcistates. One data transmission unit is used for transmitting one PDSCH. For example, in fig. 3, symbol 1 and symbol 2 constitute a data transmission unit, and symbol 6 and symbol 7 constitute a data transmission unit. Here, the PDSCH of the multi-station transmission may use the same frequency domain resource. It should be noted that, in the PDSCH transmitted in at least one data transmission unit, each data transmission unit transmits one PDSCH, and these PDSCHs may be from different TRPs, and different TRPs have different TCI states, so that the PDSCH transmitted in different data transmission units may be considered different. Taking the schematic in fig. 3 as an example, the PDSCH transmitted on symbol 1 and symbol 2 is from TRP1, the PDSCH transmitted on symbol 6 and symbol 7 is from TRP2, and TRP1 and TRP2 are different TRPs.

In the present application, only PDSCH is taken as an example for description, and the method disclosed in the present application may also be applied to repeat transmission of other downlink data.

Illustratively, the first time domain unit is a slot, and correspondingly, one data transmission unit in the slot is a time domain resource occupied by transmitting one physical downlink shared channel.

S430, the terminal equipment transmits data on at least one data transmission unit in the first time domain unit. Here, the terminal device may perform uplink transmission or downlink transmission in at least one data transmission unit, which is not limited herein. For example, a terminal device may receive PDSCH from different network devices (e.g., different TRPs) on at least one data transmission unit.

In the embodiment of the application, the terminal device obtains a first transmission frequency through a first preset relationship, an initial position of a time domain resource and a duration length of the time domain resource; then, the terminal equipment determines the time domain position of at least one data transmission unit according to the first transmission times; finally, the terminal device transmits data on at least one data transmission unit in the first time domain unit. Here, the terminal device may determine the first transmission number without increasing DCI overhead, which is beneficial to saving DCI overhead.

How the terminal device determines the first transmission times based on the first preset relationship, the start position of the time domain resource, and the duration length of the time domain resource will be described in detail below.

As an implementation manner, the first preset relationship is: and the initial position of the time domain resource, the duration of the time domain resource and the corresponding relation of the first transmission times. Wherein, S410 includes: and the terminal equipment searches the corresponding first transmission times in the first preset relation based on the initial position of the time domain resource and the continuous length of the time domain resource.

Exemplarily, the first preset relationship may be understood as a table consisting of S, L and K1. After the terminal device obtains S and L, the value corresponding to K1 can be obtained by looking up the table. Below are given 8 tables consisting of S, L and K1 at different offsets. That is, tables 1 to 8 are designed based on different default offsets, i.e., the offsets are implicitly indicated, so that DCI overhead does not need to be increased. The terminal device may look up the corresponding value of K1 in the following table based on S and L.

As a general explanation, tables 1 to 8 below are designed by taking an example in which one slot includes 14 symbols. The value of K1 in each table is designed on the principle that a certain data transmission unit does not cross a slot, i.e. the problem of transmission boundary can be avoided.

In addition, in tables 1 to 8 below, the transmission length L takes a value of {2,4,7 }. This is because, for the repeated transmission in the slot, except for the first data transmission unit, the starting symbol position S of the repeated transmission of other segments may not be in the first three symbols of the slot, so that only the transmission length with the PDSCH mapping type in the standard protocol being type B can be adopted, and therefore the value of the available transmission length L is {2,4,7 }. In the embodiment of the present application, the unit of L may be a time domain unit selected based on an actual situation, for example, the unit of L may be a symbol. In the following table, when L is 7, 2 times of repeated transmission in one slot can be performed only when S is 0 and the offset is 0, and in other cases, repeated transmission in the slot cannot be performed. When L is 7, the corresponding value of K1 can be found only in tables 1 and 9 below, and thus, L may be removed from other tables as well as from table 7.

In tables 9 to 16, if the value of K1 obtained by table lookup is x, it indicates that, according to the given S, L and offset, repeated transmission in slots cannot be performed under the condition that 1 slot includes 14 symbols at present, otherwise, the boundary problem that the data transmission unit crosses the slots occurs.

It is to be understood that one or more of tables 1 through 16 above may be predefined in the standard. The terminal device or the network device may select a corresponding table from the tables according to a default offset of the system, or based on an offset indicated by a higher layer signaling (such as an RRC signaling) sent by the network device, or based on an offset indicated by DCI sent by the network device, and then perform table lookup based on the starting symbol positions S and L to obtain the corresponding number of repeated transmissions, i.e., the first number of transmissions.

Optionally, the network device sends indication information to the terminal device, where the indication information indicates that the terminal device determines the first transmission times according to the first preset relationship. Correspondingly, the terminal equipment receives the indication information. The definition of the first predetermined relationship is explained with reference to the foregoing, and is not repeated herein. For example, the network device may send the indication information to the terminal device through RRC signaling or DCI, so as to instruct the terminal device which table to use to determine the first transmission times. Here, the terminal device may look up the first transmission number according to a table indicated by the network device.

It should also be understood that tables 1 to 16 are exemplary only and do not limit the scope of the embodiments of the present application. In fact, as the standard evolves, the values of S and L may change, but those skilled in the art can obtain the corresponding table based on the above table design principle.

As another implementation, the first preset relationship refers to a predefined formula, which may be used to calculate the first transmission number. Optionally, S410 includes: the terminal equipment calculates the first transmission times by adopting the following formula:

K1＝[(14-S-L)/(L+O1)]+1

wherein K1 is the first transmission number, S represents the starting position of the time domain resource, L represents the duration of the time domain resource, and O1 is an offset. Illustratively, O1 represents the symbol interval between each data transmission unit in a time domain unit.

O1 refers to the interval between the tail of the last data transmission unit (such as the last symbol) and the head of the next data transmission unit (such as the first symbol). O1 may be offset by default, and O1 may be an integer greater than or equal to 0. After obtaining S and L, the terminal device substitutes S, L and O1 into the above formula to calculate the value of K1.

Similarly, under the multi-station cooperation technique, when the number of TCI states existing in the transmission scenario is an even number, the first transmission number is an even number. In order to satisfy the even number of first transmissions, the above formula is adaptively adjusted assuming that K ═ [ (14-S-L)/(L + O1) ] + 1: if K is 2,4,6, K1 is K; if K is 3,5,7, K1 is K-1; if K is 1, K1 is x, where x may be explained with reference to the foregoing description and is not described herein again.

Therefore, the terminal device can obtain the corresponding first transmission times through the first preset relationship.

It should be noted that, the above describes the scheme in which the terminal device obtains the first transmission times through the first preset relationship, and similarly, the network device may also obtain the first transmission times through the first preset relationship, and for avoiding repeated description, the description is not provided here.

In this embodiment, the terminal device may determine the time domain position of the at least one data transmission unit in the first time domain unit using the first transmission times. The terminal device may further obtain the number of times of repeatedly transmitting data indicated by the network device, for example, the second number of times of transmission, and then decide which number of times of transmission to use based on a magnitude relationship between the first number of times of transmission and the second number of times of transmission. As will be described in detail below.

Optionally, the method 400 further comprises: the network equipment sends a Radio Resource Control (RRC) signaling to the terminal equipment, wherein the RRC signaling comprises a second transmission frequency, and the second transmission frequency is the frequency of repeatedly transmitting data in a time domain unit, which is indicated to the terminal equipment. Correspondingly, the terminal equipment receives Radio Resource Control (RRC) signaling from the network equipment. Wherein, S420, includes: the terminal equipment selects the minimum transmission times from the second transmission times and the first transmission times; and the terminal equipment determines the time domain position of at least one data transmission unit in the first time domain unit according to the minimum transmission times.

That is, the terminal device compares the first transmission times obtained based on the first preset relationship with the second transmission times configured by the network device, then selects the minimum transmission times, and determines the time domain position of at least one data transmission unit in the first time domain unit based on the minimum transmission times. For example, if the first transmission times are smaller than the second transmission times, the first transmission times are selected; or, if the first transmission times is greater than the second transmission times, selecting the second transmission times. Therefore, if the second transmission times configured by the network device is too large, the first transmission times can play a role in restriction, and the situation that the time domain resources are not transmitted enough can be avoided. Or, if the first transmission times obtained by the terminal device based on the first preset relationship is too large, but the transmission does not need to be performed by the too large transmission times, the second transmission times may play a role in restriction, so that other services may be scheduled in the first time domain unit, which is beneficial to improving the spectrum efficiency. Here, the second number of transmissions is indicated by the network device through RRC signaling, and DCI overhead does not need to be increased.

For convenience of description, the first transmission number is K1, and the second transmission number is K2. In dynamic scheduling, due to real-time scheduling, there may be other services already existing on some symbols in the time domain unit, and the terminal device may occupy a relatively later symbol in the slot when determining the data transmission unit, in this case, if the terminal device determines the data transmission unit only by using K2, time domain resources may be insufficient, and therefore actual transmission needs to be limited by the starting symbol positions S and L of scheduling. Describing the example in fig. 5, assuming that symbols 0 to 4 are occupied by other services, S is 5, L is 2, the default offset is 1 symbol, and in this case, in the case of 2 TRP transmissions, the terminal device obtains K1 is 2 through a first preset relationship (for example, table 10 or a calculation formula). Assuming that the number of transmissions K2 configured by the network device is 4, then min { K2, K1} ═ min {4,2} ═ 2, the terminal device may select K1 ═ 2 as the actual number of repeated transmissions, and determine two data transmission units in slot1, where the first data transmission unit occupies symbol 5 and symbol 6, and the second data transmission unit occupies symbol 8 and symbol 9.

Alternatively, for the case where K1 is greater than K2, the terminal device may preferentially select K2 repeated transmissions including the most TCI states in chronological order of increasing order in determining the data transmission unit in order to secure diversity gain. Here, with reference to the example in fig. 6, assuming that K1 is 4, K2 is 2, S is 1, L is 2, the default offset O1 is 1 symbol, and the terminal device selects K2 is 2 as the actual number of repeated transmissions.

As shown in fig. 6, in the first case, the data sent by the network device 1 is in the first data transmission unit (occupying symbol 1 and symbol 2) and the third data transmission unit (occupying symbol 7 and symbol 8), and the data sent by the network device 2 is in the second data transmission unit (occupying symbol 4 and symbol 5) and the fourth data transmission unit (occupying symbol 10 and symbol 11). The terminal device selects two data transmission units among the four data transmission units based on the actual number of times of repetitive transmission being 2. Here, the terminal device selects the first data transmission unit and the second data transmission unit based on the time-series ascending order on the principle of including the maximum TCI states from different network devices.

As shown in fig. 6, in the second case, the data sent by the network device 1 is in the first data transmission unit (occupying symbol 1 and symbol 2) and the second data transmission unit (occupying symbol 4 and symbol 5), and the data sent by the network device 2 is in the third data transmission unit (occupying symbol 7 and symbol 8) and the fourth data transmission unit (occupying symbol 10 and symbol 11). The terminal device selects two data transmission units among the four data transmission units based on the actual number of times of repetitive transmission being 2. Here, the terminal device selects the first data transmission unit and the third data transmission unit on the basis of the chronological order of increasing order on the principle of including the most TCI states from different network devices.

Therefore, the terminal device selects the data transmission unit on the principle of including the most TCI states from different network devices, contributing to achieving diversity gain.

It should be understood that the examples in fig. 5 to 6 are only for facilitating the understanding of the embodiments of the present application by those skilled in the art, and are not intended to limit the embodiments of the present application to the specific scenarios illustrated. It will be apparent to those skilled in the art that various equivalent modifications or variations are possible in light of the examples shown in fig. 5-6, and such modifications or variations are intended to be included within the scope of the embodiments of the present application.

For the network device, if the two transmission times are K1 and K2, respectively, assuming that there is no other traffic except the traffic transmitted by the network device, for example, the network device only needs to transmit PDSCH and does not need to transmit other traffic or reference signals, then K2 configured by the network device through RRC should be the same as K1. Assuming that K2 is different from K1, and K1 is greater than K2, it may be determined by the terminal device according to its own capability that the channel estimation can be completed without K1 receptions; or K1 is smaller than K2, which may be due to a fact that a time domain starting position of the repeated transmission is relatively backward (for example, an index value of S is relatively large because a front part of symbols in a slot are occupied by other traffic or reference signals), whereas K2 is configured semi-statically, which may cause a situation that K2 is too large, and if a data transmission unit is determined in a slot according to K2, a time domain resource position of the data transmission unit may exceed a slot range. For the different cases of K1 and K2, no matter whether K1 is greater than K2 or K1 is less than K2, the network device should transmit according to K1, and then the terminal device compares K1 with K2 and selects the minimum number of transmissions.

The above describes a scheme for performing repeated data transmission in a time domain unit, and the following describes a scheme for repeatedly transmitting data between time domain units. It should be understood that the above scheme for repeatedly transmitting data in the time domain unit and the following scheme for repeatedly transmitting data between time domain units may be used in combination, or may be used independently, and are not limited thereto.

Fig. 7 shows a schematic flow chart of a method 700 of determining resource allocation according to another embodiment of the present application. As shown in fig. 7, the method 700 includes:

s710, the terminal equipment acquires a first time domain offset; the first time domain offset is an offset of a starting position of a first time domain resource corresponding to a first data transmission unit in a second time domain unit relative to a starting position of a second time domain resource, where the starting position of the second time domain resource is located in the second time domain unit and is the same as the starting position of the time domain resource corresponding to the first data transmission unit in the first time domain unit used by the terminal device, for example, the same indicates that an index corresponding to the starting position is the same, for example, a symbol with an index of 5 in a slot1 and a symbol with an index of 5 in a slot2 are called as the same index; or the starting position is the same as the first symbol of the time domain unit where the starting position is located, or the starting position is the same as the relative position between the first symbol of the time domain unit where the starting position is located, for example, the relative position of symbol 5 in slot1 to the first symbol 0 of slot1 is 5-0 ═ 5; the relative position of symbol 5 in slot2 with respect to the first symbol 0 in slot2 is 5-0-5, which is said to be the same length or the same relative position. It will be understood by those skilled in the art that the time domain unit is only a slot, and the starting position of the time domain resource is a symbol starting position, which are similar to time domain units of other granularities.

The first time domain unit is the first time domain unit in the time domain units for repeatedly transmitting data, and the second time domain unit is any time domain unit except the first time domain unit in the time domain units for repeatedly transmitting data.

The "time domain unit of repeatedly transmitted data" may be a plurality of time domain units, e.g., a plurality of slots. In this embodiment, the first time domain unit is a first slot of the multiple slots, and the second time domain unit is any slot of the multiple slots except the first slot.

Optionally, the first time domain offset may be applied to any slot of the plurality of slots except the first slot. That is to say, when determining the starting position of the first time domain resource corresponding to the first data transmission unit in the subsequent slot, the terminal device may determine the starting position of the first time domain resource corresponding to the first data transmission unit by using the corresponding first time domain offset, that is, except for the first slot, the positions used for transmitting the PDSCH in the other slots are the same. Or, the network device may configure a time domain offset for each slot, and values of the time domain offsets may be different, so that flexible scheduling of time domain resources can be more achieved.

For example, the first time domain offset may be understood as an offset between data transmission units in two time domain units defined in a differential manner. For example, the Index1 is the actual symbol position corresponding to the first data transmission unit in the second time domain unit; index2 is the symbol position corresponding to the first data transmission unit determined in the second time domain unit when the terminal device follows the symbol position actually corresponding to the first data transmission unit in the first time domain unit, where the first time domain offset may represent the offset between two Index values, for example, if Index1 has a value of 2 and Index2 has a value of 4, the offset between two Index values is 4-2.

Optionally, the method 700 further includes: the terminal device obtains a first transmission frequency, where the first transmission frequency refers to the frequency of repeatedly transmitting data in a time domain unit. For example, the first transmission number refers to the number of times data is repeatedly transmitted in a slot. Specifically, the number of times data is repeatedly transmitted in the time domain unit is the same as the number of data transmission units included in the time domain unit. The first transmission number may be considered as the number of data transmission units in one time domain unit.

The embodiment of the present application does not limit the manner of acquiring the first transmission times. Optionally, the terminal device may obtain the first transmission times by using the first preset relationship described in the foregoing embodiment, or may receive the configuration of the network device.

Optionally, the acquiring, by the terminal device, the first transmission times includes: the terminal equipment receives a first signaling from network equipment, wherein the first signaling comprises the first transmission times, and the first signaling is any one of the following: downlink control information DCI, radio resource control RRC and a media access control layer control element MAC CE.

The network device may dynamically configure the first number of transmissions via the DCI. For example, the network device uses 1 bit to indicate the first transmission times, a bit value of 0 indicates that the first transmission times is 2, and a bit value of 1 indicates that the first transmission times is 4. For another example, the network device uses 2 bits to indicate the first transmission times, a bit value of 0 indicates that the first transmission times is 1, a bit value of 1 indicates that the first transmission times is 2, a bit value of 2 indicates that the first transmission times is 4, and a bit value of 3 indicates that the first transmission times is 6.

The network device may also directly configure the first transmission times through RRC signaling or MAC CE, for example, a value range of the first transmission times may be {2,4,6 }.

Optionally, S710 includes: the terminal device receives a second signaling from the network device, wherein the second signaling comprises the first time domain offset, and the second signaling is any one of the following: downlink control information DCI, radio resource control RRC, and a medium access control layer control element (MAC CE).

The network device may dynamically configure the first time domain offset through the DCI. For example, the network device indicates the first time domain offset by 2 bits, specifically, bit 00 indicates that the first time domain offset is 0, bit 01 indicates that the first time domain offset is 1, bit 10 indicates that the first time domain offset is 2, and bit 11 indicates that the first time domain offset is-1. For another example, the network device indicates the first time domain offset by 3 bits, specifically, bit 000 indicates that the first time domain offset is 0, bit 001 indicates that the first time domain offset is 1, bit 010 indicates that the first time domain offset is 2, bit 011 indicates that the first time domain offset is 3, bit 100 indicates that the first time domain offset is 4, bit 101 indicates that the first time domain offset is-1, bit 110 indicates that the first time domain offset is-2, and bit 111 indicates that the first time domain offset is-3. The positive and negative values of the first time domain offset are used to distinguish left or right offsets, for example, the positive value of the first time domain offset indicates right offset, and the positive value of the first time domain offset indicates left offset, which is not limited specifically.

Alternatively, the network device may configure the first time domain offset through RRC signaling or MAC CE. The value range of the first time domain offset is flexible. For example, if the duration L of the time domain resource is 2, the range of the first time domain offset is [ -12, +12], and there are 25 values, and the specific value is not specifically limited.

Alternatively, the network device configures predefined rules and/or combinations through RRC signaling and indicates through DCI. For example, the network device configures a combination {0, -2, +2, +4} through RRC signaling, and then indicates a value of the first time domain offset in the combination through a small number of bits, which is not specifically limited.

Alternatively, the first time domain offset may be a predefined value, for example, any value of {0, 1,2, 3, 4}, which can be directly acquired by the terminal device, which is not limited herein.

It should be understood that when the first time domain offset is 0, the time domain resource locations of the repeated transmissions in each time domain unit are the same.

S720, the terminal equipment determines the time domain position of the first data transmission unit in the second time domain unit according to the first time domain offset.

In this embodiment of the present application, after obtaining the first time domain offset, the terminal device may determine the time domain position of the first data transmission unit in the second time domain unit again. In this way, the index number corresponding to the time domain position of the first data transmission unit in the second time domain unit may not be used. The benefits of this are: if burst service or service with higher priority needs to be transmitted in the second time domain unit, time domain resources can be made for the service by introducing the first time domain offset, so that flexible scheduling of the time domain resources is realized.

Optionally, the method 700 further includes: the terminal equipment determines the time domain position of at least one data transmission unit in a second time domain unit according to the first time domain offset, the first transmission times and the second time domain offset; the second time domain offset represents a symbol interval between each data transmission unit in the second time domain unit.

Specifically, after determining the time domain position of the first data transmission unit in the second time domain unit, the terminal device may further determine the time domain position of at least one data transmission unit in the second time domain unit, that is, each data transmission unit for repeatedly transmitting data in the second time domain unit.

Optionally, the method 700 further includes: the terminal device receives a third signaling from the network device, where the third signaling includes the second time domain offset, and the third signaling is any one of the following: downlink control information DCI, radio resource control RRC and a media access control layer control element MAC CE.

The network device may dynamically configure the second time domain offset through the DCI. For example, the network device indicates the second time domain offset by 1 bit, specifically, bit 0 indicates that the second time domain offset is 0, and bit 1 indicates that the second time domain offset is 1. For another example, the network device indicates the second time domain offset by 2 bits, specifically, bit 00 indicates that the second time domain offset is 0, bit 01 indicates that the second time domain offset is 1, bit 10 indicates that the second time domain offset is 2, and bit 11 indicates that the second time domain offset is 3, which is not limited in particular.

Alternatively, the network device may configure the second time domain offset through RRC signaling or MAC CE. The value range of the second time domain offset is flexible. For example, the second time domain offset has a value range of [0, 12], and 13 values in total, which is not limited in this respect.

Alternatively, the second time domain offset may be a predefined value, for example, any value of {0, 1,2, 3, 4}, which can be directly obtained by the terminal device, which is not limited herein.

Optionally, the method 700 further includes: the terminal equipment acquires a third transmission frequency, wherein the third transmission frequency is the same as the number of the time domain units for repeatedly transmitting the data; and the terminal equipment transmits data on the time domain units with the same number as the third transmission times according to the third transmission times. Here, the third number of transmissions may be understood as a number for determining the time domain unit. For example, if the third transmission number is 2, the terminal device needs to perform data transmission on two slots.

For ease of understanding, this is described herein in connection with the schematic in FIG. 8. Assuming that the second transmission number is K2 ═ 2, as shown in fig. 8, there are two time domain units that repeatedly transmit data, for example, slot1 and slot 2. Assuming that the first transmission number K1 is 2 and L is 2, each slot includes two data transmission units as shown in fig. 8. Wherein the first data transmission element in slot1 occupies symbol 1 and symbol 2 and the second data transmission element occupies symbol 6 and symbol 7. Assuming that the first time domain offset is O2 ═ 1, as shown in fig. 8, the first time domain offset is an offset between the starting symbol position (i.e., symbol 2) actually corresponding to the first data transmission unit in slot2 and the starting symbol position (i.e., symbol 1) corresponding to the first data transmission unit (corresponding to symbol 1 and symbol 2) shown by the dashed box. The first data transmission unit shown by the dashed box refers to: the terminal device uses the data transmission unit determined at the starting symbol position (i.e. starting symbol is 1) coinciding with that in slot 1. Assuming that the second time domain offset O1 is 3 and the duration L of the time domain resource is 2, the first symbol of the second data transmission unit and the last symbol of the first data transmission unit in slot2 are separated by 3 symbols as shown in fig. 8. Therefore, as shown in fig. 8, the terminal device can obtain the symbol position of the data transmission unit in slot2 based on O2, O1, and L.

Embodiments of the present application are further described herein in connection with the example of fig. 9. Assuming that O1 is 3, O2 is 4, K1 is 2, K2 is 2, and [ S, L ] is [1,2], the terminal device can obtain the resource allocation shown in fig. 9 based on the values of O1, O2, K1, K2, and [ S, L ]. Specifically, the terminal device may determine two data transmission units in slot1 based on [ S, L ], O1 ═ 3, and K1 ═ 2, where the first data transmission unit occupies symbol 1 and symbol 2, and the second data transmission unit occupies symbol 6 and symbol 7. Then, the terminal device may obtain that the first symbol position of the first data transmission unit of slot2 is 5 based on O2 being 4. Further, the terminal device obtains the second data transmission unit as symbol 10 and symbol 11 based on L ═ 2 and O1 ═ 3. Here, since the traffic for data transmission in slot1 has been successfully interpreted with a high probability, the priority of the subsequent repeated transmission data can be lowered. After introducing O2, the data transmission unit in slot2 for transmitting the traffic may shift forward or backward, and make the resource location for other higher priority traffic or urgent traffic or signals (such as channel state information reference signal (CSI-RS)) to avoid collision with other higher priority traffic or urgent traffic, as shown in fig. 9, the burst traffic or the traffic or signals with higher priority need to be transmitted on symbols 0 to 4 in slot2, and to avoid scheduling collision, O2 is set to 4 in fig. 9, so that the PDSCH is transmitted on symbol 5, symbol 6, symbol 10 and symbol 11 in slot2, so that the traffic can be scheduled reasonably simultaneously.

For another example, taking the schematic example in fig. 9 as an example, the data transmission unit in slot1 occupies

symbols

1,2,6,7, and if there is no emergency traffic, the data transmission unit in slot2 may also use the symbol index in slot1, that is,

symbols

1,2,6, 7; but if emergency traffic occurs in slot2 and needs to be transmitted on

symbols

1,2,6,7, collisions can be effectively avoided by setting O2. For example, setting O2 ═ 2 or O2 ═ 3 (not shown in fig. 9), so that the data transmission unit in slot2 shifts to the right in the time domain, and if O2 ═ 2, shifts 2 symbols to the right, or, if O2 ═ 3, shifts 3 symbols to the right, can yield

symbols

1,2,6,7, thereby effectively avoiding collision.

Optionally, another form of the first time domain offset is also provided in the embodiments of the present application. The first time domain offset may be an offset between a starting symbol position of the second time domain unit and a starting symbol position corresponding to a first data transmission unit in the second time domain unit. As shown in fig. 10, in the upper diagram of fig. 10, the first time domain offset O2 is 2, i.e., the offset between the starting symbol position (symbol 0) of shot2 and the actual symbol position (symbol 2) of the first symbol of the first data transmission unit of slot 2.

Optionally, the embodiment of the present application further provides another form of the first time domain offset. The first time domain offset may be an offset between a last symbol position of a last data transmission unit of the first time domain unit and a starting symbol position corresponding to a first data transmission unit in the second time domain unit. As shown in fig. 10, in the lower diagram of fig. 10, the first time domain offset O2 is 8, i.e., the offset between the last symbol position (symbol 7) of the last data transmission unit of the shot1 and the actual symbol position (symbol 2) of the first symbol of the first data transmission unit of the slot 2.

Thus, the terminal device may determine the time domain location of the first data transmission unit in the second time domain unit using the various forms of first time domain offset described above.

It should be noted that, the above describes a scheme in which the terminal device determines the time domain position of the first data transmission unit in the second time domain unit through the first time domain offset, and similarly, the network device may also determine the time domain position of the first data transmission unit in the second time domain unit through the first time domain offset, and for avoiding redundancy, the description is not repeated here. It should be understood that the examples in fig. 8 to 10 are only for facilitating the understanding of the embodiments of the present application by those skilled in the art, and are not intended to limit the embodiments of the present application to the specific scenarios illustrated. It will be apparent to those skilled in the art that various equivalent modifications or variations may be made in the examples of fig. 8 to 10, and such modifications or variations also fall within the scope of the embodiments of the present application.

The application also provides a method for determining resource allocation, which comprises the following steps:

the terminal equipment determines a first transmission frequency based on the duration length of the time domain resource, wherein the first transmission frequency refers to the frequency of repeatedly transmitting data in a time domain unit; the terminal equipment determines the time domain position of at least one data transmission unit in a first time domain unit according to the first transmission times; and the terminal equipment transmits data on at least one data transmission unit in the first time domain unit.

Specifically, the terminal device may determine a value of the first transmission number according to the duration of the time domain resource. Then, the terminal device determines at least one data transmission unit in the first time domain unit by using the first transmission times, and performs data transmission.

In an embodiment, the terminal device determines a value of the first transmission time based on the first preset relationship and the duration of the time domain resource.

Illustratively, for the normal cyclic prefix PDSCH mapping type of type B duration length {2,4,7} and the extended cyclic prefix PDSCH mapping type of type B duration length {2,4,6} in the current standard protocol, the first preset relationship may be defined as: when L >2 (e.g., L ═ 4,6,7), the first transmission number takes a value of 2; when L is not greater than 2 (e.g., L — 2), the first transmission number takes a value of 4. In this way, the terminal device can determine the value of the first transmission frequency based on the value of the L in combination with the first preset relationship.

In this embodiment, the first predetermined relationship between the first transmission time and the duration of the time domain resource (for example, when the first transmission time is K1, when L is 2, K1 is 4, and when L >2, K1 is 2) makes the resource utilization more reasonable. In particular, with reference to the method of the first preset relationship as a table, it can be seen that for the case where the number of TCI states is even: in tables 9-16, when L is 4 or 7, the only possible K1 in a slot is 2, that is, each TRP can only transmit a PDSCH once, otherwise, the first transmission time is x, that is, the time-domain repeated transmission in the slot cannot be performed; in tables 9-16, when L ═ 2, a possible first number of transmissions of 2/4/6 can be obtained, i.e., 1/2/3 PDSCHs per TRP transmission. The PDSCH with L-2 has a higher code rate than the PDSCH with L-4/7, so that when only 1 PDSCH is transmitted per TRP, the reliability is poor, especially when there is a difference in transmission power between two TRPs. Therefore, 2-time PDSCH transmission per TRP is a more reasonable transmission case for L ═ 2, which can avoid that PDSCH transmission occupies too much time domain resource and can also avoid that transmission reliability can not meet the URLLC requirement.

Therefore, the terminal device can obtain the corresponding first transmission times based on the value of the L according to the first preset relation. For example, when L is 4,6,7, the first transmission number takes a value of 2, and 1 PDSCH is transmitted per TRP in the case of 2 TRPs; when L is 2, the first transmission number takes a value of 4, and 2 PDSCHs are transmitted per TRP in the case of 2 TRPs. For another example, when L >2, the first transmission number takes a value of 2, and 1 PDSCH is transmitted per TRP under 2 TRPs; when L is 2, the first transmission number takes a value of 4, and 2 PDSCHs are transmitted per TRP in the case of 2 TRPs.

It should be noted that, the above describes a scheme in which the terminal device obtains the first transmission times through the first preset relationship and the duration of the time domain resource. Similarly, the network device may also obtain the first transmission times through the first preset relationship, and for avoiding redundancy, the first transmission times are not described in detail here.

In an embodiment, the terminal device may also determine the first transmission number according to a starting position of the time domain resource and a duration of the time domain resource.

Illustratively, taking the starting position of the time domain resource as S, the duration of the time domain resource as L, the first transmission number as K1, and one slot consisting of 14 symbols as an example, the first predetermined relationship may be defined as shown in table 17 below.

TABLE 17

From the above table 17, the terminal device can obtain K1 at different L. In table 17, K1 is 2 when L is 4,6 or 7, where the time domain location of the PDSCH is determined according to S; k1 is determined in combination with L and S when L ═ 2, specifically, K1 is 4 when L ═ 2 and S belong to [0,6 ]; when L is 2 and S belongs to [7,10], K1 is 2. In this way, the PDSCH may not occupy the entire slot, and the symbols at the tail of the slot may be used for fast feedback, avoiding uplink symbols, or for other terminal devices.

The present application further provides a method for determining resource allocation, which can determine a first transmission number according to the number of certain parameters (for example, the number of Transmission Configuration Indication (TCI) states or the number of DMRS ports), and specifically includes:

in one embodiment, the terminal device determines a first transmission frequency based on the number of the TCI states indicated by the transmission configuration, where the first transmission frequency refers to the number of times data is repeatedly transmitted in a time domain unit;

the terminal equipment determines the time domain position of at least one data transmission unit in a first time domain unit according to the first transmission times;

and the terminal equipment transmits data on at least one data transmission unit in the first time domain unit.

Optionally, the first preset relationship refers to a corresponding relationship between the number of certain parameters and the first transmission times. The terminal device may determine the first transmission times directly according to values of some parameters according to the first preset relationship.

Optionally, the certain parameters may refer to TCI status, DMRS port, or other parameters, which are not particularly limited.

The terminal device may determine the first transmission times according to the number of TCI states. Illustratively, in a case where the terminal device determines that the current transmission mode is a repeated transmission in the first time domain unit, if the terminal device receives N TCI states in one transmission process, the first transmission number is N, that is, each TCI state is associated with one repetition number. For example, if there are 2 TCI states in the transmission process, the first number of transmissions is 2. Or, the terminal device receives N TCI states in one transmission process, where the first transmission time may be M × N, where M is a positive integer, that is, each TCI state is associated with M repetition times; where "+" indicates multiplication. For example, if 2 TCI states exist during transmission, the first transmission number is 4. Here, M is introduced to embody repetitive transmission. M may be determined in conjunction with various factors, such as transmission delay requirements, available transmission resources, and the like.

Or, the terminal device receives N TCI states in one transmission process, where the first transmission number may be M × N, where M is a positive integer, and M may have different values according to the duration of the time domain resource. For example, in the case where N is 2 (i.e., 2 TRPs), when L is 4,6 or 7, M is 1; when L is 2, M >1, for example, M may be 2 or 3. That is, in the case where N is 2 (i.e., 2 TRPs), when L is 4,6 or 7,1 repetition number, i.e., the first transmission number is 2, is associated with each TCI state; when L is 2, 2 or 3 repetitions are associated with each TCI state, i.e., the first transmission number is 4 or 6.

Similarly, the terminal device may determine the first transmission number according to the data of the DMRS port. Exemplarily, in a case that the terminal device determines that the current transmission mode is the repeated transmission in the first time domain unit, if the number of DMRS ports used by the terminal device is 1, that is, if the network devices all perform single-layer transmission, the first transmission number is 4, that is, the transmission number is increased to enhance reliability; if the number of DMRS ports used by the terminal device is greater than 1, that is, the network devices perform multi-layer transmission, the first transmission number is 2.

The application also provides a method for determining resource allocation, and the terminal device obtains which time domain units are utilized to determine the first transmission times by obtaining the RRC signaling sent by the network device. For example, the network device instructs the terminal device to determine the first number of transmissions using several symbols as boundaries through RRC signaling. The method provided by the embodiment comprises the following steps:

the method comprises the steps that terminal equipment receives Radio Resource Control (RRC) signaling from network equipment, wherein the RRC signaling is used for informing the terminal equipment of a first time domain unit;

the terminal equipment determines a first transmission frequency according to a first preset relation and the duration length of the time domain resource, wherein the first transmission frequency refers to the frequency of repeatedly transmitting data in the first time domain unit;

the terminal equipment determines the time domain position of at least one data transmission unit in the first time domain unit according to the first transmission times;

Specifically, the terminal device can know the first time domain unit according to the RRC signaling sent by the network device. And then, the terminal equipment determines the first transmission times according to the first preset relation and the continuous length of the time domain resource. The first transmission number refers to the number of times data is repeatedly transmitted in the first time domain unit. And the terminal equipment determines at least one data transmission unit in the first time domain unit according to the first transmission times and carries out data transmission.

Optionally, the RRC signaling includes one or more of the following information: the number of symbols occupied by the first time domain unit, the starting symbol position of the first time domain unit, and the ending symbol position of the first time domain unit. Here, the network device may inform the terminal device in which time domain units the first transmission number is determined by RRC signaling.

Illustratively, the network device may notify the terminal device of the boundary of the first time domain unit through RRC signaling, or notify the terminal device of the number of symbols occupied by the first time domain unit, or the starting symbol of the first time domain unit, or which symbols are occupied by the first time domain unit, or the index of the symbols occupied by the first time domain unit.

The first time domain unit may occupy one slot, or may occupy a part of symbols in one slot. Alternatively, the symbols occupied by the first time domain unit may be continuous or discrete, which is not limited to this.

Illustratively, the network device may notify the terminal device through RRC signaling that only the first half of one slot, or a part of symbols in one slot, can be used for multi-station time domain repeat transmission. That is, the first half of the slot may be used for repeating data transmission and the second half may be used as feedback.

Optionally, the RRC signaling may also indicate the first time domain unit through an enabling function. Taking an example where one slot includes 14 symbols, the RRC signaling includes two types of functions, type1 and type2, type1 indicates the entire slot, and type2 indicates a partial symbol (e.g., first half symbol) of the slot. Specifically, for example, if the network device enables type1 through RRC signaling, the terminal device knows that the first time domain unit is 14 symbols through RRC signaling; if the network device enables type2 through RRC signaling, the terminal device knows that the first time domain unit is the first 7 symbols in the slot through RRC signaling. For example, assuming that 1 slot occupies 14 symbols, the first time domain unit may be defined as the first 7 symbols in the slot. The terminal device may perform PDSCH repeated transmission on the first 7 symbols in the slot, that is, the terminal device calculates the first transmission times by using the 7 symbols, and the specific manner for calculating the first transmission times may refer to the foregoing description, and is not described herein again for brevity. It should be understood that the first time domain unit occupies 7 symbols for illustration, and the scope of the embodiments of the present application is not limited thereto, and in fact, the first time domain unit may also be other shorter symbols.

Here, for a symbol or a time domain unit in a slot except for the first time domain unit, the symbol or the time domain unit may be left free and reserved for other purposes, for example, in 14 symbols of a slot, the network device may reserve the second half symbol in the slot for fast feedback, or reserve the symbol for other terminal devices for transmission, which is not limited herein.

For example, the RRC signaling sent by the network device to the terminal device includes the first symbol number. The terminal device can know the boundary of the time domain unit used for calculating or determining the first transmission times, namely the boundary of the first time domain unit based on the first symbol number. The terminal device determines the first transmission times by using the method in the above embodiment with the first symbol number as a boundary, and determines the time domain position of at least one data transmission unit in the first time domain unit to perform data transmission.

For convenience of description, the first transmission number K1 is described here. For example, for the terminal device, if the RRC signaling (including the first symbol number) sent by the network device is not received, the terminal device determines the first transmission number according to the first preset relationship in which one slot includes 14 symbols in the foregoing embodiment, the starting position of the time domain resource and the duration of the time domain resource, for example, if the offset between PDSCHs is 0, then K1 ═ 6 can be obtained according to the first preset relationship (table lookup or calculation by formula) in which one slot includes 14 symbols; however, if the terminal device receives RRC signaling including the first symbol number and assumes that the first symbol number is 7 symbols, the terminal device calculates K1 using a first preset relationship designed with the symbol number of 7, and obtains a new number of transmissions of K2, where S is 0 and L is 2, and K1 is 2. At this time, the terminal device may select K1 ═ 2 as the actual number of repeated transmissions, and determine the time domain positions of two data transmission units in the time domain unit.

For example, the first predetermined relationship designed with the first time domain unit being 7 symbols is shown in the following table 18:

S＝0

S＝1

S＝2

S＝3

S＝4

S＝5

S＝6

L＝2

L＝4

L＝7

x

In table 18 above, when L is 2, K1 is 2 if S is 0, or 1, or 2, or 3. And K1 takes the value x for L4 or 7. x may also be a default number indicating that repeated transmission in the slot cannot be performed, or may be replaced by a "-" symbol, or may be replaced by other symbols not indicating a number, which is not particularly limited.

In the embodiment of the application, the network device configures the first time domain unit for the terminal device through the RRC signaling, so that time domain resources occupied by PDSCH transmission of a certain terminal device can be reduced, fast feedback and multi-user scheduling in the time domain unit are realized, and system reliability is improved.

The application also provides a method for determining resource allocation, and the network device can inform the terminal device of the first transmission times through RRC signaling. The method specifically comprises the following steps:

the network equipment sends RRC signaling to the terminal equipment, wherein the RRC signaling is used for indicating the first transmission times. Correspondingly, the terminal device receives the RRC signaling from the network device.

The terminal equipment determines the time domain position of at least one data transmission unit in a first time domain unit according to the first transmission times; and the terminal equipment transmits data on at least one data transmission unit in the first time domain unit.

Here, the terminal device may obtain the first number of transmissions by receiving RRC signaling sent by the network device.

Specifically, the network device indicates a joint between a time domain resource allocation configuration (time domain resource allocation configuration) of the existing PDSCH and the first transmission frequency, and informs the terminal device of the joint indication through the RRC signaling, so that the terminal device obtains the first transmission frequency based on the RRC signaling. Therefore, the network device enhances the RRC signaling to realize joint indication of the PDSCH TD-RA and the first transmission times without increasing DCI overhead. In addition, since the network device can pre-configure the time domain resource and the uplink and downlink symbols, the situation of uplink and downlink symbol collision in the time domain repeat transmission process can be well solved.

In the prior art of Rel-15, there are two methods for a network device to configure time domain resource allocation configuration (time domain resource allocation configuration) of PDSCH: method 1. use the default time domain resource allocation table; method 2. configuring an RRC cell (information element) related to PDSCH time domain resource allocation, such as PDSCH-time domain allocation list, and forming a time domain resource allocation table by using elements in the RRC cell.

For method 2, the structure of the RRC IE pdsch-timedomainallactosionlist is as follows:

here, the parameters included in the RRC IE pdsch-timedomainallclositionlist structure may refer to descriptions in existing protocols, and for brevity, are not described herein again. Wherein, the RRC parameter startsymbol and length is SLIV, and default indicates S and L of one PDSCH. Therefore, the network device may jointly indicate Time Domain Resource Allocation (TDRA) and the first transmission times by enhancing the RRC signaling.

The network device performs joint indication on the TDRA and the first transmission times through RRC signaling, which specifically includes the following various implementation manners:

mode 1

The network device adds an RRC parameter, such as repetiontiTimes, for configuring the number of repetitions to the RRC signaling to indicate the first number of transmissions. Wherein, the RRC signaling further includes startsymbol and length. startsymbol and length are used to indicate the PDSCH of the first segment of the repeated transmission. The network device jointly configures two parameters, namely startsymbol length and repeptitiontimes, so that the repeatedly transmitted resource allocated for the terminal device does not exceed a slot boundary.

For example, in mode 1, the structure of RRC IE pdsch-timedomainallactonlist is as follows:

mode 2

The network device adds an RRC parameter, such as offset betweenreception, for configuring an offset between repeated transmissions in RRC signaling to configure an offset between multiple repetitions. And, the network device may indicate whether to perform the repeated transmission using the RRC parameter. For example, if the offset betweenreception is not included in the RRC signaling, it indicates that the time domain retransmission is not performed, and the single station transmission or the retransmission in other modes may be performed; if the offset betweenrepetition, for example, a 0 symbol or a 1 symbol, is configured in the RRC signaling, it indicates that the first transmission number may be fixed, for example, the first transmission number is 2, or a parameter (for example, repetiontimes) in mode 1 may be further added in the RRC signaling to indicate the first transmission number. Similarly, the network device may further configure startsymbol and length, in combination with offset betweenreterication, so that the repeatedly transmitted resource allocated to the terminal device does not exceed the slot boundary.

For example, in mode 2, the structure of RRC IE pdsch-timedomainallactonlist is as follows:

mode 3

The network device adds RRC parameters configuring the starting symbol position and the duration of the repeated transmission, such as startsymbol and length and repetition, in the RRC signaling to indicate S, L, Repetition the joint coding result. The offset (offset) corresponding to the RRC parameter is fixed, for example, the offset is 0 or 1 symbol.

There are various joint encoding methods of S, L, Repetition, but the method is not limited to this. For example, if Repetition is K1 and L satisfies 0< L ≦ 14-S, S, L, K1 may satisfy the following formula:

if L-1 is less than or equal to 7, SLIV _ R ═ 14 × (L-1) + S ] × K1;

otherwise, SLIV _ R ═ K1 [14 × (14-L +1) + (14-1-S) ], where L-1 is greater than 7.

The startsymbol and length and repetition is the value indicated by SLIV _ R. A SLIV _ R value represents a combination of S, L, K1. However, at this time, the maximum value of the SLIV _ R may not be 127 due to the addition of the coding element, and the maximum value of the SLIV _ R needs to be extended to 255 or 511 according to the joint coding mode. The embodiment of the present application does not limit the encoding manner and the possible values of the SLIV _ R.

For example, in mode 3, the structure of RRC IE pdsch-timedomainallactonlist is as follows:

mode 4

The network device adds another RRC parameter configuring the starting symbol position and the duration of the repeated transmission, such as second startsymbol and length, to the RRC signaling to indicate the value of the second SLIV. In this case, when configuring the value of the second SLIV, the network device needs to ensure that the starting symbol of the second SLIV is after the ending symbol of the first SLIV, that is, there cannot be an overlap on symbols between the two SLIVs; in addition, when configuring the value of the second SLIV, the network device may also avoid the uplink symbol position in advance according to the configuration manner of the uplink and downlink symbol positions in the time domain unit, and configure the first SLIV and the second SLIV, thereby solving the situation of uplink and downlink symbol collision in the time domain repeat transmission process.

For example, in mode 4, the structure of RRC IE pdsch-timedomainallactonlist is as follows:

mode 5

The network device configures RRC parameters of the list of starting symbol positions and duration lengths, such as listofstartsymbol andlength, in RRC signaling to represent the sequence of the multiple SLIVs. The network device may optionally configure multiple SLIV values to represent the time domain resource locations for multiple repeated transmissions. In this manner, the configuration limitations of multiple SLIV may be similar to the SLIV configuration in manner 4. Here, the beneficial effect of using multiple SLIV configurations is similar to that of manner 4, and therefore, for brevity, will not be described herein again.

For example, in mode 5, the structure of RRC IE pdsch-timedomainallactonlist is as follows:

it should be noted that, for the above-listed structure of RRC IE pdsch-timedomainnalockationlist, some parameters included therein may refer to descriptions in the existing protocol, and for brevity, detailed descriptions are omitted here.

For the terminal device, after receiving the RRC signaling in any of the above manners, the terminal device may obtain the first transmission times through the RRC signaling.

It is to be understood that this embodiment can be implemented alone or in combination with the foregoing embodiments, and is not limited thereto. For example, where "the network device configures the first transmission times for the terminal device through RRC signaling" in the foregoing embodiment, a specific implementation manner of RRC signaling in the embodiment may be adopted.

In another implementation, the network device sends a signaling to the terminal device, and indicates to the terminal device that one of a plurality of preset first transmission times is in effect, for example, the preset first transmission time is K1-2 or K1-4, the network device may issue the signaling to the terminal device, and enable K1-2 to be in effect; the terminal equipment receives the signaling, determines the repeated transmission times to be 2, otherwise determines the repeated transmission times to be 4; the network device may also issue a signaling to the terminal device, where the enable K1 becomes effective when being equal to 4, and the terminal device receives the signaling and determines that the number of times of retransmission is 4, and otherwise determines that the number of times of retransmission is 2.

The signaling may be RRC signaling, or MAC-CE signaling, or DCI signaling.
