Description

Resource allocation method and network node

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource allocation method and a network node.

Background

With the continuous development of mobile communication technology, spectrum resources have become increasingly strained. Currently, the unallocated frequency spectrum available for wireless communication is very limited, and in order to improve the frequency utilization, future base station deployments will be more intensive, and the intensive base station deployments will require the backhaul link of the base station to have corresponding transmission capability. However, in many scenarios, for example, the deployment cost of optical fiber is very high, which may increase the deployment cost of future wireless base stations. For this reason, the relay scheme including a wireless Relay Node (RN) can be adopted to solve the problem of deployment of dense base stations in the future well.

In a new generation wireless communication system (NR), a relay scheme is called Integrated Access and Backhaul (IAB). In IAB, a relay node is referred to as an IAB node (IAB node). The IAB node is divided according to functions and may include: a Mobile Termination (MT) function and a Distributed Unit (DU) function. The IAB node communicates with a superior node through the MT, and a link where the MT communicates with the superior node (parent node) is called a superior backhaul link. The IAB node communicates with a subordinate node (child node) or a User Equipment (UE) through a DU, and a link where the DU communicates with the subordinate node or the UE is called an access link (access link).

In order to improve the frequency spectrum efficiency of the IAB node, and further improve the whole capacity of the IAB network. NR will introduce an enhancement of the co-operation of the IAB node MT with the DU, i.e. Spatial Division Multiplexing (SDM) or full duplex transmission by the IAB node. At this time, the IAB node may need to perform joint signal processing of the MT and the DU. In order to improve the link detection performance during the joint signal processing, the MT transceiving reference signal and the DU transceiving reference signal need to be orthogonalized. The existing resource allocation method can not ensure the time domain alignment of the reference signals of the MT and the DU and can not meet the orthogonalization requirement of the reference signals. Therefore, a resource allocation method is needed to meet the above requirement.

Disclosure of Invention

The embodiment of the application provides a resource configuration method and a network node, wherein the network node sends an uplink reference signal to a superior node (or a host node) based on specific configuration information, and the specific configuration information is associated with a specific timing mode so as to meet the orthogonalization requirement of an IAB node for receiving and sending the reference signal in a new timing mode scene. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved.

In a first aspect, an embodiment of the present application provides a resource allocation method, which may include:

the first node receives first configuration information sent by a second node, wherein the first configuration information is associated with a first timing mode of a Mobile Terminal (MT) of the first node, and the first configuration information indicates a first time domain position where the first node sends an uplink reference signal. In an alternative implementation, the first configuration information may be associated with a plurality of timing modes simultaneously. In an alternative implementation, the first time domain position may be a sign bit. The value range of the sign bit can be the sign 1 (indicated as "pos 1"), the sign 2 (indicated as "pos 2"), the sign 3 (indicated as "pos 3"), the sign 4 (indicated as "pos 4"), and the like;

and the first node sends the uplink demodulation reference signal to a second node based on the first configuration information, wherein the second node is a superior node or a host donor node of the first node. The reference signal may be a demodulation reference signal (DMRS) in the LTE protocol or the NR protocol, or may also be another reference signal defined in the LTE protocol or the NR protocol or a future protocol for implementing the same or similar functions, for example: phase-tracking reference signals (PT-RS), channel-state information reference signals (CSI-RS), Sounding Reference Signals (SRS), or the like.

In this embodiment of the application, a first node sends an uplink reference signal to a second node based on specific first configuration information, where the second node is a higher node or a host node of the first node. The first configuration information is associated with the first timing mode of the mobile terminal MT of the first node, so as to meet the orthogonalization requirement of the IAB node for receiving and transmitting the reference signal in the new timing mode scenario. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method may further include:

the first node receives second configuration information sent by the second node, where the second configuration information indicates a second time domain position where the first node sends an uplink reference signal in a second timing mode, and the second timing mode includes timing mode 1. The second configuration information may include: a symbol index of the starting position of the uplink reference signal, or an offset of the starting position of the uplink reference signal, or indication information of the second timing pattern, or the DMRS configuration type information, or the time domain position information of the additional DMRS, or the DMRS sequence initialization parameter, or the DMRS sequence type information, or a preconfigured code division multiplexing group identifier, or an unused code division multiplexing group identifier.

Timing mode 1 is MT or in IAB nodeA basic uplink timing mode of the UE. In timing mode 1, the second node (upper IAB node or base station) adjusts the transmission advance of the MT of the first node (lower IAB node), so that the uplink frame of the first node is aligned with the uplink frame of other UE or IAB node MT (the other UE is a child node of the second node) in the uplink receiving window of the second node. The transmission advance may be a Timing Advance (TA). In the protocol, the advance TA is denoted as T_TAAnd T is_TA＝(N_TA+N_TA,offset)T_cWhere Tc is a time unit defined in the NR standard, N_TAObtained by configuration and update of the upper node, and N_TA,offsetA band-dependent offset configured for a protocol definition or a superordinate node.

In the embodiment of the application, a first node receives first configuration information and second configuration information. The first node transmits an uplink reference signal to a second node based on the first configuration information or based on the second configuration information, wherein the second node is a superior node of the first node. The first configuration information is associated with a first timing mode of the mobile terminal MT of the first node. The second configuration information is associated with a second timing mode of the MT of the first node. The second timing mode may be timing mode 1. The first node may send the uplink reference signal to the second node using different configuration information, where the different configuration information is respectively associated with different timing modes, so as to meet an orthogonalization requirement of the IAB node for receiving and sending the reference signal in a new timing mode scenario. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first timing mode may include: timing mode6, or timing mode 7.

Specifically, the method comprises the following steps: timing mode7 is similar to timing mode 1, and in timing mode7, the second node adjusts the transmission advance of the MT of the first node, so that symbol level alignment is achieved between the DU uplink received signal and the MT downlink received signal in the second node. The transmission advance may be a TA + offset (offset), and the offset may be configured by the second node or by a third node, where the third node is a node superior to the second node (or a donor node).

When the first node adopts timing mode7, the downlink reception time of the MT in the second node is aligned with the uplink reception time of the DU in the third node. It should be understood that, from the perspective of the first node, the embodiment of the present application mainly considers that the timing pattern 7 of the first node has an offset from the basic timing pattern 1, but does not limit the timing alignment effect achieved by the timing pattern 7 at the second node, for example, the second node may configure the first node to adopt the timing pattern 7, and align the uplink reception of the DU of the second node with the uplink transmission of the MT of the second node through an appropriate offset configuration, thereby implementing simple self-interference cancellation.

To support spatial multiplexing for IAB, timing mode6 is introduced. Timing mode6 may enable simultaneous transmission of an MT uplink for the IAB node and a DU downlink for the IAB node. It should be noted that the first timing mode may also be other timing modes, such as: timing mode 2, timing mode 3, timing mode 4, timing mode 5, etc., and are not limited herein.

In this embodiment, the first timing mode may include multiple timing modes, so as to meet the requirement of orthogonalizing the reference signals received and transmitted by the IAB node in multiple timing mode scenarios.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first configuration information includes:

the symbol index of the starting position of the uplink reference signal is, for example, "pos 2" or "pos 3". The meaning is: when the symbol index of the starting position of the uplink reference signal is "pos 2", it indicates that the symbol index of the starting position of the uplink reference signal is 2, that is, symbol 2 of the uplink slot carries the symbol of the first uplink reference signal.

In another optional implementation manner, the first configuration information includes an offset of a starting position of the uplink reference signal, where the offset refers to an offset of the first time domain position relative to a time domain position of a DMRS broadcast by the base station. Specifically, in the existing protocol, a base station (e.g. a second node) configures a UE or an IAB node MT with starting symbols of pre-DMRSs for an uplink PUSCH and a downlink PDSCH through broadcast signaling (e.g. MIB or SIB 1). Optionally, the information element is "DMRS-type a-Position", and values of the information element are "pos 2" and "pos 3", indicating that an index of the first pre-DMRS symbol is symbol 2 or symbol 3. The first configuration information may indicate an offset of the first time domain position from the DMRS position, which may be [ -2, -1, 0, 1, 2], and for example, when the starting position of the broadcast signaling configuration is the symbol 2 "pos 2" and the offset is configured to "-1", the obtained first time domain position is the symbol 1 "pos 1".

In this embodiment, the first configuration information may include a symbol index of a starting position of the uplink reference signal, and/or an offset of the starting position of the uplink reference signal. The first time domain position is indicated through various methods, and the implementation flexibility of the scheme is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first configuration information further includes: indication information of the first timing mode. The indication information of the first timing mode is used for indicating the first node, and what timing mode the first timing mode associated with the first configuration information is specifically. The indication information of the first timing mode may be a field in the first configuration information, for example, when the indication information of the first timing mode is "XXX", the first timing mode is timing mode 7; when the indication information of the first timing pattern is "YYY", the first timing pattern is timing pattern 6. The indication information of the first timing mode may also be a certain bit in the first configuration information, for example, when the certain bit in the first configuration information is "01", the first timing mode is indicated as timing mode 6; when a certain bit in the first configuration information is "00", it indicates that the first timing mode is timing mode 7. The indication information of the first timing mode may indicate the first timing mode implicitly, in addition to explicitly indicating the first timing mode, for example: when the field 'ZZZ' appears in the first configuration information, the first timing mode associated with the first configuration information is a timing mode 6; when the field "ZZZ" is not present in the first configuration information, the first timing mode associated with the first configuration information is timing mode 7.

In this embodiment, the first configuration information may include indication information of the first timing mode. The indication information of the first timing mode can be realized by a plurality of methods, and the realization flexibility of the scheme is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, when the uplink reference signal is a demodulation reference signal DMRS, the first configuration information further includes one or more of the following information: the DMRS configuration type information, the time domain position information of the additional DMRS, the DMRS sequence initialization parameter, the DMRS sequence type information, the pre-configured code division multiplexing group identification and the unused code division multiplexing group identification.

Specifically, the DMRS configuration type information may be configuration type 1(configuration type 1) or configuration type 2(configuration type 2). For a single-symbol DMRS design, that is, a DMRS port spans one symbol in the time domain, Resource Elements (REs) in the symbol may be divided into two groups by frequency domain positions, for example, a DMRS configuration type1 is set of REs labeled as 0 and 1, and each group of REs is arranged in a comb shape in the frequency domain. In the protocol, two groups of REs are referred to as code division multiplexing group 0(CDM group 0) and code division multiplexing group 1(CDM group 1), respectively. In the protocol of the present stage, each CDM group may multiplex two DMRS ports by code division. Thus, a DMRS frequency-domain pattern within one RB may multiplex 4 DMRS ports, e.g., ports 1000, 1001, 1002, 1003. The DMRS ports belonging to different CDM groups are orthogonal by frequency division multiplexing, and the DMRS ports belonging to the same CDM group are orthogonal by (frequency domain) code division.

DMRS configuration type 2(DMRS configuration type 2): first, for DMRS design of a single symbol, REs within the symbol may be divided into three groups by frequency domain location, i.e., sets of REs denoted as 0, 1, and 2 in DMRS configuration type 2 in fig. 3, each group of REs being adjacent to each other in frequency domain, and in the protocol, referred to as code division multiplexing group 0(CDM group 0), code division multiplexing group 1(CDM group 1), and code division multiplexing group 2(CDM group 2), respectively. In the protocol of the present stage, each CDM group may multiplex two DMRS ports by code division. Thus, DMRSs within one RB can multiplex 6 DMRS ports, denoted as ports 1000, 1001, 1002, 1003, 1004, 1005, respectively. The DMRS ports belonging to different CDM groups are orthogonal by frequency division multiplexing, and the DMRS ports belonging to the same CDM group are orthogonal by (frequency domain) code division.

Further, for dual-symbol DMRS design, i.e., a DMRS port spans 2 symbols in the time domain, when one DMRS port occupies one or more subcarriers on two consecutive time domain symbols, time domain Orthogonal Cover Codes (OCC) {1, 1} and {1, -1} may be further introduced. By using OCC codes for two consecutive DMRS symbols in the time domain, the number of orthogonal ports can be doubled. For example, for DMRS configuration type1, the number of available DMRS ports is increased to 8 by OCC codes, and for DMRS configuration type 2, the number of available ports is increased to 12 by OCC codes.

For high-speed or high-doppler frequency offset scenarios, in order to make channel estimation more accurate, an additional dmrs (additional dmrs) may also be added. In this application, the first configuration information is applicable to the NR pre-DMRS, and is also applicable to the case of the pre-DMRS plus the additional DMRS. The time domain location information of the additional DMRS indicates that the first node transmits the additional DMRS at a specified time domain location. It should be noted that, in this embodiment of the application, the first configuration information may configure a single-symbol DMRS, may also configure a dual-symbol DMRS, and may also configure a multi-symbol DMRS, which is not limited herein.

DMRS sequence type information, in LTE and NR, a DMRS sequence may be a pseudo-random sequence, for example: "Gold sequence", may also be a "ZC sequence", and may also be a computer search sequence. The sequence type of the UE or the IAB node MT may be configured by the base station or the upper node, or may be implicitly inferred by the UE or the IAB node based on information such as a waveform and a channel type.

DMRS sequences initialize parameters, which need to generate a local sequence based on an initial parameter when DMRS employs a pseudo-random sequence, e.g., "Gold sequence", and the initialization parameters may be generated by a cell ID or may be configured by a base station.

And the pre-configured code division multiplexing group identification indicates that the superior node only schedules ports in the one or more groups of code division multiplexing groups. The value is determined by the DMRS configuration type, for example, for DMRS configuration type1, the preconfigured code division multiplexing group may be one or both of 0 and 1; and for DMRS configuration type 2, the preconfigured code division multiplexing groups may be one, two, or three of 0, 1, and 2;

the unused code division multiplexing group identity, also called reserved code division multiplexing group identity, indicates that the upper node will not schedule ports within the one or more code division multiplexing groups. The value is determined by the DMRS configuration type, for example, for DMRS configuration type1, the unused code division multiplexing group may be one of 0 and 1; and for DMRS configuration type 2, the preconfigured code division multiplexing groups may be one or two of 0, 1, and 2. The code division multiplex group identity not used by the first node may also be derived from a pre-configured code division multiplex group identity, for example: when the DMRS configures type1, the preconfigured code division multiplexing group identity is 0, and the code division multiplexing group identity that is not used is 1.

The first node determines usable CMD group identifications based on the unused code division multiplexing group identifications, and realizes port orthogonalization of the DMRS through the usable code division multiplexing groups. Optionally, the upper node (second node) does not map data modulation symbols at the time domain position of the unused CDM group, so that it can be ensured that the first node can implement the orthogonalization of the reference signals of the MT and the DU through reasonable DU scheduling, for example, the first node can always perform reference signal indication of the DU scheduling in the code division multiplexing group reserved by the upper node.

In this embodiment, when the uplink reference signal is a DMRS, the first configuration information may include a plurality of types of configuration information related to the DMRS. So as to meet the orthogonalization requirement of the IAB node for receiving and transmitting the reference signal. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved. The link detection performance of the first node can also be improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, the method further includes:

and the first node receives first indication information sent by the second node, wherein the first indication information is used for indicating a timing mode adopted by the first node. Specifically, the first indication information is used to indicate an explicit manner in which the first node uses the first timing mode, and the current timing mode may be determined by inference from other existing parameters.

In an optional implementation manner, the first configuration information may be associated with multiple timing modes at the same time, and the first node selects one timing mode in the first configuration information to transmit the uplink reference signal based on the first indication information. For example: the first configuration information is associated with timing mode6 and timing mode7 at the same time, and the first indication information is "a" and indicates the first node to use timing mode6, or the first indication information is "B" and indicates the first node to use timing mode 7.

In another alternative implementation, the first indication information may be carried in a separate signaling (separate from the first configuration information). For example: MAC CE for timing mode indication, scheduling Downlink Control Information (DCI), and the like. The first node determines the employed timing mode to be the first timing mode based on the first indication information. Optionally, the first indication information may be a field, for example, when the first indication information includes a field "mode 7", the first node is indicated to use timing mode 7; when the first indication information includes the field "mode 6," the first node is indicated to use timing mode 6. The indication information of the first timing mode may also be a bit, for example, when a certain bit in the first configuration information is "01", the first node is indicated to use timing mode 6; when a bit in the first configuration information is "00", the first node is instructed to use timing mode 7.

Optionally, when the timing mode6 and the timing mode7 are configured by the first configuration information, and the bit indicating the timing mode7 in the first indication information is "0", the first node determines that the employed timing mode is the timing mode6 based on the first indication information.

In an alternative implementation, when the first configuration information configures timing mode6 and timing mode7, when the bit indicating timing mode6 in the first indication information is "0" (timing mode6 is not used), and the bit indicating timing mode7 is "0" (timing mode7 is not used), the first node determines that the adopted timing mode is timing mode 1 based on the first indication information.

In the first indication information, a field or a bit or the like that plays a role of indication may be referred to as a first parameter. For example: the first indication includes a field "mode 7" indicating that the first node uses timing mode7, in which case the first parameter is the field "mode 7". When a certain bit in the first configuration information is "01", indicating that the first node uses the timing mode6, and at this time, the first parameter is the bit "01";

when the first indication information indicates a first timing mode, the first node sends an uplink reference signal by using the first configuration information; and when the first indication information indicates a second timing mode, the first node sends an uplink reference signal by using the second configuration information.

In the embodiment of the application, the first indication information can be realized in multiple ways, so that the realization flexibility of the scheme is improved. The second node sends the first indication information to the first node, so that the first node can select different timing modes to send the uplink reference signal under the indication of the second node. So as to meet the orthogonalization requirement of the IAB node for receiving and transmitting the reference signal. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved. The link detection performance of the first node can also be improved.

the first node determines an adopted timing mode based on a transmission mode parameter set and a first parameter carried in the first indication information, wherein the transmission mode parameter set is configured by the second node, the transmission mode parameter set comprises a first transmission mode parameter and/or a second transmission mode parameter, the first transmission mode parameter is associated with the first timing mode, and the second transmission mode parameter is associated with the second timing mode. Illustratively, when a first transmission mode parameter in the set of transmission mode parameters is "1", the first transmission mode parameter "1" is associated with timing mode6 in the first timing mode; when the first transmission mode parameter is "2", the first transmission mode parameter "2" is associated with the timing mode7 in the first timing mode; when the second transmission mode parameter is "0", the second transmission mode parameter "0" is associated with timing mode 1 in the second timing mode.

It should be noted that the transmission mode parameter set may also be implemented by a set of functions, for example: the second node configures the first node with a set of transmission mode parameters implemented as a set of functions, referred to as the first function. After the first node is configured with the first function, the first parameter from the second node is input to the first function. The resulting output values of the first function are called transmission mode parameters, different transmission mode parameters being associated with different timing modes. The first node determines a timing mode to be employed by the first node based on an output value of the first function.

In the first indication information, a field or a bit or the like that plays a role of indication may be referred to as a first parameter. For example: the first indication includes a field "mode 7" indicating that the first node uses timing mode7, in which case the first parameter is the field "mode 7". When a bit in the first configuration information is "01", the first node is instructed to use the timing mode6, and at this time, the first parameter is the bit "01".

In this embodiment of the application, the second node may further configure a transmission mode parameter set to the first node and send the first indication information, so that the first node may select different timing modes to send the uplink reference signal under the indication of the second node. So as to meet the orthogonalization requirement of the IAB node for receiving and transmitting the reference signal. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved. The link detection performance of the first node can also be improved. Moreover, the realization flexibility of the scheme is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, before the receiving, by the first node, the first configuration information sent by the second node, the method further includes:

the first node sends a configuration information request to the second node, wherein the configuration information request is used for requesting the second node to configure an orthogonalized port for the first node. The first node is configured with a first port set by the second node, the first port set comprises a port set or a reserved port set, and ports in the first port set are orthogonalized.

When the first node sends the uplink reference signal to the second node based on the first configuration information, in order to implement port orthogonalization, the first node needs to send a configuration information request to the second node, where the configuration information request is used to request the second node to configure an orthogonalized port for the first node. The orthogonalized port may be a set of ports, referred to as a first port set, which may be one or more ports. Illustratively, the first set of ports includes: all ports comprised in

group

0 or 1 are code division multiplexed.

The first port set includes a port set or a reserved port set. The ports included in the port set are ports which can be used by the first node, and the ports included in the reserved port set are ports which cannot be used by the first node. And when the port set is configured in the configured first port set, the first node transmits the uplink reference signal based on the port set. When the reserved port set is configured in the configured first port set, the first node selects other ports except the reserved port set to send uplink reference signals based on the reserved port set, and the other ports are orthogonalized ports.

In this embodiment of the present application, the first node may further enable the second node to configure a first port set to the first node by sending a configuration information request to the second node, where the first port set includes an orthogonalized port. The method comprises the steps of transmitting a mode parameter set and sending first indication information, so that a first node can select different timing modes to send uplink reference signals under the indication of a second node. So as to meet the orthogonalization requirement of the IAB node for receiving and transmitting the reference signal. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved. The link detection performance of the first node can also be improved. Moreover, the realization flexibility of the scheme is improved.

With reference to the first aspect, in a possible implementation manner of the first aspect, the first configuration information is carried in a unicast signaling, for example: radio Resource Control (RRC) signaling, or medium access control sublayer control element signaling (MAC CE). In addition, the first configuration information may also be carried in other high layer signaling, which is not limited herein; the second configuration information is carried in broadcast signaling. For example, the second configuration information is carried in MIB information or SIB1 information. In addition, the second configuration information may also be carried in other higher layer signaling, which is not limited herein.

In a second aspect, an embodiment of the present application provides a resource allocation method, including:

a second node sends first configuration information to a first node, wherein the first configuration information is associated with a first timing mode of a Mobile Terminal (MT) of the first node, the first configuration information indicates a first time domain position of an uplink reference signal sent by the first node, and the second node is a superior node or a host donor node of the first node;

and the second node receives an uplink reference signal sent by the first node, wherein the uplink reference signal is an uplink reference signal sent by the first node to the second node based on the first configuration information. The reference signal may be a demodulation reference signal (DMRS) in the LTE protocol or the NR protocol, or may also be another reference signal defined in the LTE protocol or the NR protocol or a future protocol for implementing the same or similar functions, for example: phase-tracking reference signals (PT-RS), channel-state information reference signals (CSI-RS), Sounding Reference Signals (SRS), or the like.

In an embodiment of the present application, a second node sends first configuration information to a first node, and the second node receives an uplink reference signal sent by the first node, where the uplink reference signal is an uplink reference signal sent by the first node to the second node based on the first configuration information. The second node is a superior node or a host node of the first node. The first configuration information is associated with the first timing mode of the mobile terminal MT of the first node, so as to meet the orthogonalization requirement of the IAB node for receiving and transmitting the reference signal in the new timing mode scenario. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved.

With reference to the second aspect, in a possible implementation manner of the second aspect, the method further includes:

the second node sends second configuration information to the first node, where the second configuration information indicates a second time domain position of the first node for sending the uplink reference signal in a second timing mode, and the second timing mode includes timing mode 1.

The second timing mode includes timing mode 1. The second configuration information may include: a symbol index of the starting position of the uplink reference signal, or an offset of the starting position of the uplink reference signal, or indication information of the second timing pattern, or the DMRS configuration type information, or the time domain position information of the additional DMRS, or the DMRS sequence initialization parameter, or the DMRS sequence type information, or a preconfigured code division multiplexing group identifier, or an unused code division multiplexing group identifier.

Timing mode 1 is the basic uplink timing mode of the MT or UE in the IAB node. In timing mode 1, the second node (upper IAB node or base station) adjusts the transmission advance of the MT of the first node (lower IAB node), so that the uplink frame of the first node is aligned with the uplink frame of other UE or IAB node MT (the other UE is a child node of the second node) in the uplink receiving window of the second node. The transmission advance may be a Timing Advance (TA). In the protocol, the advance TA is denoted as T_TAAnd T is_TA＝(N_TA+N_TA,offset)T_cWhere Tc is a time unit defined in the NR standard, N_TAObtained by configuration and update of the upper node, and N_TA,offsetA band-dependent offset configured for a protocol definition or a superordinate node.

In the embodiment of the application, the second node sends the first configuration information and the second configuration information to the first node. The first node transmits an uplink reference signal to a second node based on the first configuration information or based on the second configuration information, wherein the second node is a superior node of the first node. The first configuration information is associated with a first timing mode of the mobile terminal MT of the first node. The second configuration information is associated with a second timing mode of the MT of the first node. The second timing mode may be timing mode 1. The first node may send the uplink reference signal to the second node using different configuration information, where the different configuration information is respectively associated with different timing modes, so as to meet an orthogonalization requirement of the IAB node for receiving and sending the reference signal in a new timing mode scenario. And further, the frequency spectrum efficiency of the IAB node is improved, and the whole capacity of the IAB network is improved.

With reference to the second aspect, in a possible implementation manner of the second aspect, the first timing mode includes: timing mode6, or timing mode 7.

With reference to the second aspect, in a possible implementation manner of the second aspect, the first configuration information includes: a symbol index of the starting position of the uplink reference signal, or an offset of the starting position of the uplink reference signal.

It should be understood that in the integrated access and backhaul system shown in fig. 1, one IAB node is connected to one upper node, but in a future relay system, in order to improve the reliability of the wireless backhaul link, one IAB node, e.g., 120, may have multiple upper nodes simultaneously serving it, e.g., the IAB node 130 in the figure may also be connected to the IAB node 120 through the backhaul link 134, i.e., the IAB node 110 and the IAB node 120 are both upper nodes of the IAB node 130. In the present application, the terminals 101,111,121,131 may be stationary or mobile devices. For example, the mobile device may be a mobile phone, a smart terminal, a tablet computer, a notebook computer, a video game console, a multimedia player, even a mobile IAB node, and the like. Stationary devices are typically located at fixed locations such as computers, access points (connected to the network by wireless links, such as stationary IAB nodes), and the like. The names of

IAB nodes

110, 120, 130 do not limit the scenario or network in which they are deployed, and may be any other names such as relay, RN, rrtp, etc. The use of IAB nodes in this application is only needed for ease of description.

IAB nodes are also called relay nodes, and each IAB node includes two functional entities, namely a Distributed Unit (DU) and a Mobile terminal (Mobile Termination), wherein the MT functional entity is similar to the function of a UE and receives downlink data from an upper node (a Donor an IAB node) or transmits uplink data to an upper node, and the DU functional entity is similar to the function of a base station and transmits downlink data to a lower node (an IAB node or a Mobile terminal) or receives uplink data transmitted by a lower node.

In fig. 1, the wireless links 102,112,122,132,113,123, 133,134 may be bidirectional links, including uplink and downlink transmission links, and in particular, the wireless backhaul links 113,123, 133,134 may be used for an upper node to provide service to a lower node, such as the upper node 100 providing wireless backhaul service to the lower node 110. It should be understood that the uplink and downlink of the backhaul link may be separate, i.e., the uplink and downlink are not transmitted through the same node. The downlink transmission refers to transmission of information or data to a higher node, such as the node 100, and to a lower node, such as the node 110, and the uplink transmission refers to transmission of information or data to a lower node, such as the node 110, and to a higher node, such as the node 100. The node is not limited to being a network node or a terminal, for example, in the D2D scenario, a terminal may serve other terminals as a relay node. The wireless backhaul link may in turn be an access link in some scenarios, e.g. backhaul link 123 may also be considered as an access link for node 110, and backhaul link 113 is also an access link for node 100. It should be understood that the above-mentioned upper node may be a base station, and may also be a relay node, and the lower node may also be a terminal having a relay function, for example, in the D2D scenario, the lower node may also be a terminal.

In fig. 1, the Donor node refers to a node through which a core network can be accessed, or an anchor base station of a radio access network through which a network can be accessed. The anchor base station is responsible for data processing of a Packet Data Convergence Protocol (PDCP) layer, or is responsible for receiving and forwarding data of a core network to a relay node, or receiving and forwarding data of the relay node to the core network.

When the relay node is under the half-duplex constraint, the wireless backhaul link of the in-band relay coincides with the spectrum resource of the access link, that is, the backhaul link and the access link of the in-band relay have the same frequency band. For example, when the IAB node receives the downlink wireless backhaul link of the base station, it cannot transmit to the subordinate terminal or device; while the IAB node performs uplink transmission to the upper node on the backhaul link, it cannot receive transmission of the subordinate terminal or device on the uplink access link or the backhaul link of the lower node.

The following definitions are given for some commonly used technical terms:

and accessing a link: the access link refers to a wireless link used when a certain node communicates with its subordinate nodes, and includes uplink transmission and downlink transmission links. Uplink transmission on the access link is also referred to as uplink transmission of the access link, and downlink transmission is also referred to as downlink transmission of the access link. Including but not limited to the aforementioned IAB nodes.

A return link: the backhaul link refers to a wireless link used when a certain node communicates with its upper node, where a link through which the MT communicates with the upper node is referred to as a primary backhaul link (hereinafter referred to as a primary backhaul link), and a link through which the DU communicates with the lower IAB node is referred to as a child backhaul link (hereinafter referred to as a secondary backhaul link). Including but not limited to the aforementioned IAB nodes.

The general purpose processing device is understood to be a processing device comprising necessary hardware components such as a processor and a transceiver, the operation of which depends on the processing instructions stored in the computer readable storage medium.

The method proposed in the examples of the present application will be explained below. First, some concepts related to embodiments of the present application are introduced.

First, the reference signal:

in the embodiment of the present application, the reference signal may be a demodulation reference signal (DMRS) in an LTE protocol or an NR protocol, or may also be another reference signal defined in the LTE protocol or the NR protocol or a future protocol for implementing the same or similar functions, for example: phase-tracking reference signals (PT-RS), channel-state information reference signals (CSI-RS), Sounding Reference Signals (SRS), or the like, which are not limited in this application. In the embodiment of the present application, the reference signal is an uplink DMRS.

In LTE or NR protocols, DMRS may be carried in a physical shared channel and transmitted with data signals for demodulating the data signals carried in the physical shared channel. For example, the downlink data is transmitted together with the Physical Downlink Shared Channel (PDSCH) or the uplink data is transmitted together with the Physical Uplink Shared Channel (PUSCH). The DMRS may also be carried in a physical control channel and transmitted together with the control signaling, so as to demodulate the control signaling carried in the physical control channel aggregate. For example, the PDCCH is transmitted together with downlink control signaling, or the Physical Uplink Control Channel (PUCCH) is transmitted together with uplink control signaling. In the embodiment of the present application, the demodulation reference signal may include a downlink demodulation reference signal transmitted through a PDCCH or a PDSCH, and may also include an uplink demodulation reference signal transmitted through a PUCCH or a PUSCH.

Secondly, orthogonalizing:

port orthogonalization: taking DMRS as an example, DMRS implements orthogonalization between ports by frequency division multiplexing, frequency domain code division multiplexing, and time domain code division multiplexing: frequency division multiplexing: DMRSs of different ports (or port groups) occupy different frequency domain locations. In NR, a group of DMRS ports occupying different frequency domain positions is called a code division multiplexing group. The Type1 configuration comprises two code groups which are arranged in a uniform comb shape; the type 2 configuration contains three code packets; frequency domain code division multiplexing: in one code packet, DMRS frequency domain orthogonalization may be achieved by orthogonal codes {1, 1} and {1, -1 }. With frequency domain code division multiplexing, each code packet may include two orthogonal ports; time domain code division multiplexing: DMRS orthogonalization can be achieved by orthogonal codes {1, 1} and {1, -1} between different DMRS symbols. When one time slot only comprises one preposed DMRS symbol, the configuration type1 can realize the DMRS orthogonalization of 4 ports at most, and the configuration type 2 can realize the DMRS orthogonalization of 6 ports at most. When one time slot only comprises two front DMRS symbols, the configuration type1 can realize the DMRS orthogonalization of 8 ports at most, and the configuration type 2 can realize the DMRS orthogonalization of 12 ports at most.

Time domain (sign bit) alignment: given the above, it should be noted that an important premise for implementing the orthogonalization of the DMRSs of different data streams is that DMRS symbols of different data streams are aligned in a time domain at a receiving end, that is, the DMRSs of different data streams are located in a receiving window of the same symbol at the receiving end. For example, an IAB node DU or a base station receiving DMRS symbols transmitted by multiple UEs (or MTs) should use the same symbol reception window, so as to implement DMRS orthogonalization.

Thirdly, timing mode:

first, timing pattern 1 is introduced. Timing mode 1 is the basic uplink timing mode of the MT or UE in the IAB node. In timing mode 1, the second node (upper IAB node or base station) adjusts the transmission advance of the MT of the first node (lower IAB node), so that the uplink frame of the first node is aligned with the uplink frame of other UE or IAB node MT (the other UE is a child node of the second node) in the uplink receiving window of the second node. The transmission advance may be a Timing Advance (TA). In the protocol, the advance TA is denoted TTA, and T_TA＝(N_TA+N_TA,offset)T_cWhere Tc is a time unit defined in the NR standard, N_TAObtained by configuration and update of the upper node, and N_TA,offsetA band-dependent offset configured for a protocol definition or a superordinate node.

Timing mode7 is similar to timing mode 1, and in timing mode7, the second node adjusts the transmission advance of the MT of the first node, so that symbol level alignment is achieved between the DU uplink received signal and the MT downlink received signal in the second node. The transmission advance may be a TA + offset (offset), and the offset may be configured by the second node or by a third node, where the third node is a node superior to the second node (or a donor node).

For convenience of understanding, the timing mode is described in the perspective of the second node, please refer to fig. 4a, fig. 4a is a schematic diagram of timing mode 1 and timing mode7 involved in the embodiment of the present application, and it should be understood that timing mode 1 and timing mode7 in fig. 4a are two timing modes adopted by the second node DU. When the second node DU is receiving upstream in timing mode7, the downstream reception of the MT in the second node (MT DL RX) is aligned with the upstream reception of the DU in the second node (DU UL RX). Illustratively, as shown in fig. 4a, a downlink received symbol N (e.g., symbol 0) of the MT is aligned with an uplink received symbol N +1 (e.g., symbol 1) of the DU, where N is an integer.

When the DU of the second node has two different timing modes (uplink reception timings), the MT of the lower node, that is, the MT of the first node, has two corresponding timing modes (uplink transmission timings), and it should be understood that the uplink transmission of the IAB node MT is taken as an example in this embodiment, but the method of this embodiment may also be applied to the uplink transmission timing of the UE.

Referring to fig. 4b, fig. 4b is a schematic diagram of the timing mode 1 and the timing mode7 in the embodiment of the present application at the transmitting end. In timing mode 1, the advance of the uplink transmission (MT UL TX) time of the MT in the first node relative to the downlink reception (MT DL RX) time of the MT in the first node is the Timing Advance (TA), which is specifically defined as described above. In the timing mode7, the advance of the uplink transmission time of the first node MT relative to the downlink reception time of the first node MT is the sum of the Timing Advance (TA) and an offset (offset), which may be configured by the second node or the third node (donor node).

In the above example, when the first node adopts timing mode7, the downlink reception time of the MT in the second node is aligned with the uplink reception time of the DU in the third node. It should be understood that, from the perspective of the first node, the embodiment of the present application mainly considers that the timing pattern 7 of the first node has an offset from the basic timing pattern 1, but does not limit the timing alignment effect achieved by the timing pattern 7 at the second node, for example, the second node may configure the first node to adopt the timing pattern 7, and align the uplink reception of the DU of the second node with the uplink transmission of the MT of the second node through an appropriate offset configuration, thereby implementing simple self-interference cancellation.

Next, timing pattern 6 is introduced. To support spatial multiplexing for IAB, timing mode6 is introduced. Timing mode6 may enable simultaneous transmission of an MT uplink for the IAB node and a DU downlink for the IAB node. For ease of understanding, please refer to fig. 4c at the first node, and fig. 4c is a schematic diagram of timing mode 1 and timing mode6 according to the embodiment of the present application. In timing mode6, the downlink transmission time of the DU (DU DL TX) of the first node is time-aligned with the uplink transmission time of the MT (MT UL TX) in the first node.

It should be noted that the time units aligned in fig. 4 a-4 b are time slots, that is, the MT and the DU perform time slot transmission simultaneously. The aligned time cells are not limited in practical applications, for example, the aligned time cells may also be symbols. Also, the inclusion of 14 symbols in each slot is merely illustrative.

Referring to fig. 5a, fig. 5a is a schematic diagram illustrating an embodiment of a resource allocation method according to an embodiment of the present application. It should be noted that, in the embodiment of the present application, the reference signal is described by taking the uplink DMRS as an example, and the reference signal may be: phase-tracking reference signals (PT-RS), channel-state information reference signals (CSI-RS), Sounding Reference Signals (SRS), or the like, without limitation. The resource allocation method provided by the embodiment of the application comprises the following steps:

501. the first node receives first configuration information sent by the second node.

In this embodiment, a first node receives first configuration information sent by a second node. The first configuration information is associated with a first timing mode of the mobile terminal MT of the first node, and the first configuration information indicates a first time domain position where the first node transmits the uplink reference signal.

The first timing mode includes timing mode6 or timing mode7, and it should be noted that the first timing mode may also be other timing modes, for example: timing mode 2, timing mode 3, timing mode 4, timing mode 5, etc., and are not limited herein.

In an alternative implementation, the first configuration information includes a symbol index of a starting position of the uplink reference signal, for example, "pos 2", or "pos 3". The meaning is: when the symbol index of the starting position of the uplink reference signal is "pos 2", it indicates that the symbol index of the starting position of the uplink reference signal is 2, that is, symbol 2 of the uplink slot carries the symbol of the first uplink reference signal.

Illustratively, as shown in fig. 5b, when the first timing mode is timing mode7, the first time domain position may be symbol 3 ("pos 3") of the uplink time slot, and the start position of the downlink DMRS of the second node MT is symbol 2, and as described above, the downlink reception of the second node MT and the uplink reception of the DU based on timing mode7 have a symbol offset in the time domain, so that the second node receives symbol 2 of the MT and symbol 3 of the DU in the same reception window, thereby implementing symbol bit alignment of the DMRS at the receiving end, so that the DMRS received by the MT and the DMRS received by the DU can be orthogonalized. It should be noted that, when the first timing mode is the timing mode6, the first configuration information also includes related configuration information, which is used for instructing the first node to transmit the reference signal at the first time domain position.

In another optional implementation manner, the first configuration information includes an offset of a starting position of the uplink reference signal, where the offset refers to an offset of the first time domain position relative to a time domain position of a DMRS broadcast by the base station.

Specifically, in the existing protocol, a base station (e.g. a second node) configures a UE or an IAB node MT with starting symbols of pre-DMRSs for an uplink PUSCH and a downlink PDSCH through broadcast signaling (e.g. MIB or SIB 1). Optionally, the information element is "DMRS-type a-Position", and values of the information element are "pos 2" and "pos 3", indicating that an index of the first pre-DMRS symbol is symbol 2 or symbol 3. The first configuration information may indicate an offset of the first time domain position from the DMRS position, which may be [ -2, -1, 0, 1, 2], and for example, when the starting position of the broadcast signaling configuration is the symbol 2 "pos 2" and the offset is configured to "-1", the obtained first time domain position is the symbol 1 "pos 1".

In an alternative implementation, the first time domain position may be a sign bit, such as shown in fig. 5 b. The value range of the sign bit may be the sign 1 "pos 1", the sign 2 "pos 2", the sign 3 "pos 3" or the sign 4 "pos 4", etc.

In an optional implementation manner, the first configuration information further includes indication information of the first timing mode. The indication information of the first timing mode is used for indicating the first node, and what timing mode the first timing mode associated with the first configuration information is specifically. The indication information of the first timing mode may be a field in the first configuration information, for example, when the indication information of the first timing mode is "XXX", the first timing mode is timing mode 7; when the indication information of the first timing pattern is "YYY", the first timing pattern is timing pattern 6. The indication information of the first timing mode may also be a certain bit in the first configuration information, for example, when the certain bit in the first configuration information is "01", the first timing mode is indicated as timing mode 6; when a certain bit in the first configuration information is "00", it indicates that the first timing mode is timing mode 7. The indication information of the first timing mode may indicate the first timing mode implicitly, in addition to explicitly indicating the first timing mode, for example: when the field 'ZZZ' appears in the first configuration information, the first timing mode associated with the first configuration information is a timing mode 6; when the field "ZZZ" is not present in the first configuration information, the first timing mode associated with the first configuration information is timing mode 7.

Optionally, the first configuration information is carried in unicast signaling, for example: radio Resource Control (RRC) signaling, or medium access control sublayer control element signaling (MAC CE). In addition, the first configuration information may also be carried in other higher layer signaling, which is not limited herein.

Optionally, the second node may generate the first configuration information based on an indication of the third node, and the second node may also generate the first configuration information based on its own traffic demand. The third node is a superior node or a donor node of the second node, or other upper network nodes, such as an operation and maintenance administration node (OAM).

Optionally, in consideration of various resource mapping manners of the DMRS port, in this embodiment, the first configuration information includes one or more of the following information: demodulation Reference Signal (DMRS) configuration type information, time domain position information of an additional DMRS, DMRS sequence initialization parameters, DMRS sequence type information, Code Division Multiplexing (CDM) group identifier that can be used, code division multiplexing group identifier that is not used, symbol index of a DMRS or a pre-DMRS starting position, offset of the DMRS or the pre-DMRS starting position, and indication information of a first timing pattern.

The DMRS configuration type information may be configuration type 1(configuration type 1) or configuration type 2(configuration type 2). Referring to fig. 3, fig. 3 is a schematic diagram of DMRSs under different configuration types in this embodiment. For a single-symbol DMRS design, that is, a DMRS port spans one symbol in the time domain, Resource Elements (REs) in the symbol may be divided into two groups by frequency domain positions, that is, a set of REs marked as 0 and 1 in DMRS configuration type1 in fig. 3, where each group of REs is arranged in a comb shape in the frequency domain. In the protocol, two groups of REs are referred to as code division multiplexing group 0(CDM group 0) and code division multiplexing group 1(CDM group 1), respectively. In the protocol of the present stage, each CDM group may multiplex two DMRS ports by code division. Thus, a DMRS frequency-domain pattern within one RB may multiplex 4 DMRS ports, e.g., ports 1000, 1001, 1002, 1003. The DMRS ports belonging to different CDM groups are orthogonal by frequency division multiplexing, and the DMRS ports belonging to the same CDM group are orthogonal by (frequency domain) code division.

It is noted that the above-mentioned single-symbol DMRS design or dual-symbol DMRS design refers to the number of consecutive pre-loaded DMRS symbols within a slot, and does not include additional DMRSs (additional DMRSs), which are generally added for high-speed or high-doppler frequency offset scenarios in order to make channel estimation more accurate. In this application, the first configuration information is applicable to the NR pre-DMRS, and is also applicable to the case of the pre-DMRS plus the additional DMRS. The "time domain location information of the additional DMRS" in the first configuration information indicates that the first node transmits the additional DMRS at a specified time domain location. It should be noted that, in this embodiment of the application, the first configuration information may configure a single-symbol DMRS, may also configure a dual-symbol DMRS, and may also configure a multi-symbol DMRS, which is not limited herein.

The symbol index of the starting position of the DMRS refers to the symbol index of the starting position of the DMRS in the slot, for example: the symbol index of the starting position of the DMRS is symbol 3, meaning that the 3 rd symbol position of the slot is the starting position of the DMRS. The DMRS may be a preamble DMRS.

The offset of the DMRS starting position refers to the offset of the DMRS starting position relative to the DMRS time domain position broadcasted by the base station. The DMRS may be a preamble DMRS.

And indication information of the first timing mode, which is used for indicating the first node, and what timing mode the first timing mode associated with the first configuration information is specifically.

502. And the first node receives second configuration information sent by the second node.

In this embodiment, the first node receives second configuration information sent by the second node, where the second configuration information indicates a second time domain position where the first node sends the uplink reference signal in a second timing mode, and the second timing mode includes timing mode 1.

Optionally, the second configuration information is carried in the broadcast signaling, for example, the second configuration information is carried in MIB information or SIB1 information. In addition, the second configuration information may also be carried in other higher layer signaling, which is not limited herein.

Optionally, the second configuration information is similar to the first configuration information, and is not described herein again.

It should be noted that, in the embodiment of the present application, step 501 may be executed first, and then step 502 may be executed; step 502 may be executed first, and then step 501 may be executed; step 501 and step 502 may also be performed simultaneously, and are not limited herein.

503. The first node determines the timing mode to be employed.

In this embodiment, the first node determines the adopted timing mode, and may send first indication information to the first node through the second node, where the first indication information is used to indicate that the first node uses the scheme of the first timing mode. In addition to this explicit approach, the first node may also determine the current timing mode by guessing from other existing parameters.

In an alternative implementation, the first node may determine the timing mode it employs based on the scheduled frame structure and physical resources (BWPs), with different BWPs associated with different timing modes. Illustratively, when the first node employs a first BWP, it transmits in clocked mode 1; when the first node employs the second BWP, it transmits in clocked mode 6; when the first node employs the third BWP, it transmits in clocked mode 7.

In another optional implementation manner, the first node may further acquire the timing mode according to the following information, and determine the adopted timing mode. The information includes Transmission Configuration Indicator (TCI) information, different TCIs being associated with different timing modes. Illustratively, the first TCI corresponds to timing mode 1, the second TCI corresponds to timing mode6, and the third TCI corresponds to timing mode 7;

the information may also include: SRS Resource Indicator (SRI) information, different SRIs being associated with different timing patterns. Illustratively, the first SRI corresponds to timing mode 1, the second SRI corresponds to timing mode6, and the third SRI corresponds to timing mode 7;

the information may also include: spatial relationship information (spatialrelalationinfo), different spatial relationship information being associated with different timing patterns. Illustratively, the first spatial relationship information corresponds to timing mode 1, the second spatial relationship information corresponds to timing mode6, and the third spatial relationship information corresponds to timing mode 7;

the information may also include reference signal identification information, different reference signal identification information being associated with different timing patterns. Illustratively, the first reference signal identification corresponds to timing pattern 1, the second reference signal identification corresponds to timing pattern 6, and the third reference signal identification corresponds to timing pattern 7. The information may also be other information with identification function, which is not described herein again.

In another optional implementation manner, the second node may also send second indication information to the first node, where the second indication information is used to indicate that the first node uses a second timing mode (timing mode 1), and then the first node sends the uplink reference signal to the second node based on the second configuration information.

504. When the timing mode of the first node is a first timing mode, sending an uplink reference signal to the second node based on the first configuration information; or, when the timing mode of the first node is the second timing mode, the uplink reference signal is sent to the second node based on the second configuration information.

In this embodiment, when the first indication information indicates that the first node uses the first timing mode (timing mode6 or timing mode 7), the first node sends the uplink reference signal to the second node at the first time domain position based on the first configuration information.

Or, when the first indication information (or the second indication information) indicates that the first node uses the second timing mode (timing mode 1), the first node transmits the uplink reference signal to the second node at the second time domain position based on the second configuration information.

In this embodiment of the present application, the second node sends the first configuration information to the first node, where the first configuration information is associated with the first timing mode, so that the first node sends the uplink reference signal at the first time domain location based on the first configuration information. Because the first configuration information is associated with the first timing mode, the first node may send the uplink reference signal to the second node at the first time domain position associated with the first timing mode, thereby meeting the orthogonalization requirement of the IAB node for receiving and sending the reference signal in multiple timing mode scenarios.

Further, please refer to fig. 6, where fig. 6 is a schematic diagram of another embodiment of a resource allocation method according to an embodiment of the present application. The resource allocation method provided by the embodiment of the application comprises the following steps:

601. the first node receives first configuration information sent by the second node.

In this embodiment, step 601 is similar to step 501, and is not described herein again.

602. And the first node receives second configuration information sent by the second node.

In this embodiment, step 602 is similar to step 502 described above, and is not described here again.

603. The second node configures a set of transmission mode parameters to the first node.

In this embodiment, the second node configures a transmission mode parameter set to the first node, where the transmission mode parameter set includes a first transmission mode parameter and/or a second transmission mode parameter, the first transmission mode parameter is associated with the first timing mode, and the second transmission mode parameter is associated with the second timing mode. For example, referring to table 1, table 1 shows an association relationship between transmission mode parameters and timing modes.

Transmission mode parameters	Timing mode
			1	Timing mode6
2	Timing mode7
		0	Timing mode 1

TABLE 1

Taking table 1 as an example, when a first transmission mode parameter in the transmission mode parameter set is "1", the first transmission mode parameter "1" is associated with timing mode6 in the first timing mode; when the first transmission mode parameter is "2", the first transmission mode parameter "2" is associated with the timing mode7 in the first timing mode; when the second transmission mode parameter is "0", the second transmission mode parameter "0" is associated with timing mode 1 in the second timing mode.

Optionally, other transmission mode parameters may also be included in the set of transmission mode parameters, which are associated with other timing modes. For example: a third transmission mode parameter, which may be associated with timing mode 2.

It should be noted that the transmission mode parameter set may be implemented in the manner of table 1; it can also be implemented by a set of functions, for example: the second node configures the first node with a set of transmission mode parameters implemented as a set of functions, referred to as the first function. After the first node is configured with the first function, the first parameter from the second node is input to the first function. The resulting output values of the first function are called transmission mode parameters, and different transmission mode parameters are associated with different timing modes, similar to table 1. The first node determines a timing mode to be employed by the first node based on an output value of the first function.

604. The first node sends a configuration information request to the second node.

In this embodiment, when the first node sends the uplink reference signal to the second node based on the first configuration information, in order to implement port orthogonalization, in step 604, the first node needs to send a configuration information request to the second node, where the configuration information request is used to request the second node to configure an orthogonalized port for the first node. The orthogonalized port may be a set of ports, referred to as a first port set, which may be one or more ports. Illustratively, the first set of ports includes: all ports comprised in

group

0 or 1 are code division multiplexed.

605. Based on the configuration information request, the second node configures the first port set to the first node.

In this embodiment, based on the configuration information request, the second node configures a first port set to the first node, where the first port set includes a port set or a reserved port set. The ports included in the port set are ports which can be used by the first node, and the ports included in the reserved port set are ports which cannot be used by the first node. And when the port set is configured in the configured first port set, the first node transmits the uplink reference signal based on the port set. When the configured first port set is a reserved port set, the first node selects other ports except the reserved port set to send uplink reference signals based on the reserved port set.

It should be noted that step 604 to step 605 are optional steps.

606. The second node sends the first indication information to the first node.

In this embodiment, the second node sends first indication information to the first node, where the first indication information is used to indicate that the first node uses the first timing mode. The first indication information carries a first parameter, and the first parameter is used for indicating which timing mode corresponding to the transmission mode parameter is selected by the first node.

In an alternative implementation, the first node determines the timing mode to be used according to the first parameter and the transmission mode parameter set. Illustratively, when the first parameter is "1", the first node determines, based on the first parameter and the set of transmission mode parameters (e.g., table 1), that the timing mode adopted by the first node is timing mode 6; when the first parameter is "2", the first node determines that the timing mode adopted by the first node is timing mode7 based on the first parameter and the set of transmission mode parameters (e.g., table 1).

In another alternative implementation, the first node determines the timing mode to be used solely on the basis of the first parameter. Specifically, the method comprises the following steps:

607. the first node determines the timing mode to be employed based on the first indication information.

In this embodiment, the first node determines the adopted timing mode based on the first parameter carried in the first indication information.

Illustratively, when the first parameter is "1", the first node determines, based on the first parameter and the set of transmission mode parameters (e.g., table 1), that the timing mode adopted by the first node is timing mode 6; when the first parameter is "2", the first node determines that the timing mode adopted by the first node is timing mode7 based on the first parameter and the set of transmission mode parameters (e.g., table 1).

608. The first node transmits an uplink reference signal to the second node based on the first configuration information.

In this embodiment, for example, when the first timing mode is timing mode6, the first time domain position may be symbol 2 in the slot, as shown in fig. 5c, the MT in the first node transmits an uplink reference signal at symbol 2, and the DU in the first node transmits a downlink reference signal at symbol 2, so that the DMRS transmitted by the MT and the DMRS transmitted by the DU may be orthogonalized to achieve symbol bit alignment of the DMRS at the transmitting end.

In this embodiment of the present application, the second node sends the first configuration information to the first node, where the first configuration information is associated with the first timing mode, so that the first node sends the uplink reference signal at the first time domain location based on the first configuration information. Because the first configuration information is associated with the first timing mode, the first node may send the uplink reference signal to the second node at the first time domain position associated with the first timing mode, thereby meeting the orthogonalization requirement of the IAB node for receiving and sending the reference signal in multiple timing mode scenarios. The first node may also request to send a configuration information request to the second node, such that the second node configures to the first node a first set of ports, the ports in the first set of ports being orthogonalized. Thereby further improving the link detection performance of the first node. The second node may also configure a transmission mode parameter set to the first node, and the first indication information sent to the first node by the second node carries the first parameter, so that the first node determines the adopted timing mode based on the first parameter and the transmission mode parameter set, thereby improving the implementation flexibility of the scheme.

Referring to fig. 7a, please refer to fig. 7a based on the embodiments shown in fig. 5 a-6, wherein fig. 7a is a schematic diagram of another embodiment of a resource allocation method according to the present invention. The application also provides a resource allocation method, which comprises the following steps:

701. the first node measures downlink timing when the first node receives the downlink reference signal of the second node.

In this embodiment, the first node measures downlink timing when the first node receives the downlink reference signal of the second node. Specifically, the first node sends a reference signal to the second node, and determines downlink timing when the first node receives a downlink reference signal of the second node according to a measurement value of the reference signal reported by the second node. For example, the reference signal may be a Synchronization Signal Block (SSB), a channel state information-reference signal (CSI-RS), a Tracking Reference Signal (TRS), or the like.

In an alternative implementation, the first node determines the downlink timing based on the measurement value of the reference signal and an offset (offset), which may be the same as in the previous embodiment.

Specifically, the first node determines a first downlink timing based on a measurement value of the reference signal. The first node determines a second downlink timing based on the first downlink timing and the offset. The offset may also be configured by the superordinate node.

In another optional implementation manner, the first node additionally configures the downlink timing. At this time, the downlink timing is independent of the measurement value of the reference signal reported by the second node.

702. And the first node receives the third configuration information sent by the second node.

In this embodiment, the first node receives third configuration information sent by the second node, where the third configuration information is similar to the first configuration information in the foregoing embodiments. The difference is that the third configuration information indicates that the first node receives the downlink reference signal sent by the second node at the third time domain position. The third time domain position is determined by the downlink timing obtained in step 701.

Optionally, the third time domain positions configured by different downlink timings may not be consistent, for example: in the first downlink timing, the third configuration information indicates that the first node receives a downlink reference signal sent by the second node at "pos 3"; in the second downlink timing, the third configuration information indicates that the first node receives the downlink reference signal sent by the second node at "pos 4".

It should be noted that more or less downlink timings may also be configured in the third configuration information, and time domain positions corresponding to the downlink timings may be configured by the first node based on a measurement value of the reference signal, may also be configured by the first node based on a measurement value and an offset of the reference signal, and may also be configured by the first node (or other higher node) based on actual requirements, which is not limited herein.

703. And the first node receives the fourth configuration information sent by the second node.

In this embodiment, the first node receives fourth configuration information sent by the second node, and the fourth configuration information is similar to the second configuration information in the foregoing embodiment. The difference is that the fourth configuration information indicates that the first node uses the third downlink timing, and specifically, in the third downlink timing, the first node receives the downlink reference signal sent by the second node at the fourth time domain position. Similar to the third configuration information in step 702, the fourth time domain position (third downlink timing) may also be determined by the downlink timing obtained in step 701.

Optionally, more downlink timings may also be configured in the fourth configuration information, and time domain positions corresponding to the downlink timings may be configured by the first node based on a measurement value of the reference signal, may also be configured by the first node based on a measurement value and an offset of the reference signal, and may also be configured by the first node (or other higher node) based on actual requirements, which is not limited herein.

It should be noted that step 703 is an optional step.

704. The second node sends third indication information to the first node.

In this embodiment, the second node sends the third indication information to the first node. The third indication information is used for indicating which downlink timing is used by the first node to receive the reference signal. This third indication information is similar to the first indication information in the foregoing embodiment. The difference is that the first node receives the downlink reference signal sent by the second node at the third time domain position or the fourth time domain position based on the third configuration information.

705. The first node determines the adopted downlink timing based on the third indication information.

In this embodiment, the first node determines the adopted downlink timing based on the third indication information. Specifically, the method comprises the following steps: the first node determines to use the first downlink timing, or the second downlink timing, or the third downlink timing based on the third indication information. In addition to this explicit manner, the first node may also determine the current downlink timing by inferring from other existing parameters.

In an alternative implementation, the first node may determine the downlink timing it employs based on the scheduled frame structure and the physical resource bandwidth part (BWP), with different BWPs associated with different downlink timings. Illustratively, when the first node employs a first BWP, it transmits with a first downlink timing; when the first node adopts the second BWP, the first node adopts the second downlink timing to transmit; when the first node employs the third BWP, it transmits with the third downlink timing.

In another optional implementation manner, the first node may further obtain downlink timing according to the following information, and determine the adopted downlink timing. The information includes Transmission Configuration Indicator (TCI) information, different TCIs being associated with different downlink timings. Illustratively, the first TCI corresponds to a first downlink timing, the second TCI corresponds to a second downlink timing, and the third TCI corresponds to a third downlink timing;

the information may also include: SRS Resource Indicator (SRI) information, different SRIs being associated with different downlink timings. Exemplarily, the first SRI corresponds to a first downlink timing, the second SRI corresponds to a second downlink timing, and the third SRI corresponds to a third downlink timing;

the information may also include: spatial relationship information (spatialrelalationinfo), different spatial relationship information being associated with different downlink timings. Illustratively, the first spatial relationship information corresponds to a first downlink timing, the second spatial relationship information corresponds to a second downlink timing, and the third spatial relationship information corresponds to a third downlink timing;

the information may also include reference signal identification information, different reference signal identification information being associated with different downlink timings. Illustratively, the first reference signal identifier corresponds to a first downlink timing, the second reference signal identifier corresponds to a second downlink timing, and the third reference signal identifier corresponds to a third downlink timing. The information may also be other information with identification function, which is not described herein again.

In an optional implementation manner, the fourth indication information carries an identifier associated with the configuration information, so that the first node determines which configuration information to use for sending or receiving the reference signal based on the fourth indication information. The following are exemplary: when the fourth indication information carries the identifier "type 1-1", the first node determines to transmit the reference signal using the first configuration information based on the fourth indication information. Specifically, the first node transmits the reference signal at the first time domain position by using the information related to the timing pattern 7 in the first configuration information.

When the fourth indication information carries the identifier "type 1-2", the first node determines to transmit the reference signal using the first configuration information based on the fourth indication information. Specifically, the first node transmits the reference signal at the first time domain position by using the information related to the timing mode6 in the first configuration information.

When the fourth indication information carries the identifier "type 3-1", the first node determines to receive the reference signal using the third configuration information based on the fourth indication information. Specifically, the first node receives the reference signal at the third time domain position using the first downlink timing related information in the third configuration information.
