[0002] Transmission loss on a high frequency band (FR2 band) is large, and the transmission range is relatively limited. In order to combat the high transmission loss or shielding problem on the FR2 band, a sidelink (sidelink) user equipment (User Equipment, UE) can use directional beams for transmission when transmitting on the FR2 band. For a pair of transmit (Transmit, TX) UE and receive (Receive, RX) UE, the TX UE transmits using a TX beam, and the RX UE receives using an RX beam, which can improve the signal strength or coverage of the transmission.

[0031] The signal transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0032] like Figure 2 As shown, one embodiment of the present invention provides a signal transmission method 200, which can be executed by a terminal device; in other words, the method can be executed by software or hardware installed on the terminal device. The method includes the following steps:

[0033] S202: The first terminal determines the first resource set.

[0034] The first resource set can be a time domain and / or frequency domain resource set. The resources in the first resource set can be in units of slots or other resource units. The resources in the first resource set can be resources of certain channels, such as a physical sidelink shared channel (PSSCH) or a physical sidelink feedback channel (PSFCH), or resources occupied by certain symbols in a slot.

[0035] In an implementation manner, the first resource set satisfies at least one of the following first conditions:

[0036] The size of each first resource in the first resource set is agreed upon by a protocol;

[0037] The size of each first resource in the first resource set is configured by a control node;

[0038] The size of each first resource in the first resource set is preconfigured;

[0039] The size of each first resource in the first resource set is determined by the first terminal;

[0040] The sizes of the first resources in the first resource set are the same;

[0041] The position of each first resource in the first resource set is agreed upon by a protocol;

[0042] The position of each first resource in the first resource set is configured by a control node;

[0043] The position of each first resource in the first resource set is preconfigured;

[0044] The position of each first resource in the first resource set is determined by the first terminal;

[0045] The first resources in the first resource set are continuous in time;

[0046] The first resource set is a periodic resource set.

[0047] In another implementation manner, there is a first correspondence between the first resource set and a second resource set, where the second terminal transmits the signal on the second resource set. The first correspondence includes at least one of the following:

[0048] The second resource set corresponds to the first resource set;

[0049] The second resource set corresponds to a subset of the first resource set.

[0050] A superset of the second resource set corresponds to the first resource set.

[0051] S204: receiving a signal sent by a second terminal on the first resource set.

[0052] The first terminal can receive a sending signal, such as a beam training signal, from each proximity UE on the first resource set.

[0053] The beams described throughout the application file, including receiving beams and sending beams, can each include at least one of a spatial domain filter, a precoder, a RS resource index, a transmission configuration index, an antenna panel, and the like.

[0054] In an implementation, since the first resource set satisfies at least one of the first conditions described above, the first terminal and the second terminal can have a unified understanding of the to-be-trained beam and the beam training resource.

[0055] In another implementation, the second terminal sends the signal on the second resource set. Since there is a first correspondence relationship between the first resource set and the second resource set, the first terminal and the second terminal can have a unified understanding of the to-be-trained beam and the beam training resource.

[0056] The signal transmission method provided by the embodiment of the application can determine the first resource set by the first terminal, and receive a signal sent by a second terminal on the first resource set, so as to ensure that the to-be-trained beam and the beam training resource have a unified understanding between UEs.

[0057] As shown in FIG. 3, Figure 3 An embodiment of the application provides a signal transmission method 300, which can be executed by a terminal device, in other words, the method can be executed by software or hardware installed in the terminal device, and the method comprises the following steps:

[0058] S302: The first terminal determines a first resource set.

[0059] This step can adopt the description of the embodiment step S202, which will not be repeated here. Figure 2 The embodiment step S202 is described, which will not be repeated here.

[0060] S304: receiving, on the first set of resources, the signal transmitted by the second terminal on the second set of resources via a receive beam.

[0061] The receive beam includes a preset beam or a beam determined by the first terminal. The preset beam is at least one of a protocol agreement, a control node configuration, or a pre-configuration. For example, an omnidirectional beam. In the following, the receive beam can include at least one of a first receive beam, a second receive beam, and a third receive beam, each of which can include a preset beam or a beam determined by the first terminal.

[0062] In an implementation, there is a quasi-co-location relationship between the receive beams corresponding to each first resource in the first set of resources.

[0063] In an implementation, there is a quasi-co-location relationship between the first receive beam and the second receive beam, wherein the receive beam includes the first receive beam and the second receive beam, the first set of resources includes a first set and a second set, the first receive beam corresponds to at least one first resource in the first set, and the second receive beam corresponds to at least one second resource in the second set. The receive beams with a co-location relationship correspond to the same beam.

[0064] The first set and / or the second set are at least one of a protocol agreement, a control node configuration, or a pre-configuration. The first receive beam resource and / or the second receive beam resource are at least one of a protocol agreement, a control node configuration, or a pre-configuration. For example, the resource set in which the receive beams have a quasi-co-location relationship can appear periodically, and the period is N (N >= 1) times of the period of the resource set. N = 1 means that the receive beams between the resource sets have a quasi-co-location relationship. For another example, the receive beams on the resources with the same number in the resource set have a co-location relationship. For another example, the receive beams on all resources have a co-location relationship.

[0065] In an implementation, the first set of resources includes multiple subsets, and each subset includes one or more resources. For example, a time domain resource subset includes one or more time domain resources. The first terminal receives, on the subset, the signal transmitted by the second terminal on the second set of resources via a third receive beam. The receive beam includes one or more third receive beams.

[0066] Optionally, the third receive beam can include the preset beam described above, and different directional beams are used to receive different sub-resource sets of a resource set. The different directional beams form a preset beam, such as an omnidirectional beam.

[0067] In an implementation manner, there is no quasi-co-location relationship between third receiving beams corresponding to different subsets.

[0068] In an implementation manner, there is quasi-co-location relationship between receiving beams corresponding to each first resource in a subset of the first resource set.

[0069] In another implementation manner, there is quasi-co-location relationship between a fourth receiving beam and a fifth receiving beam, wherein the receiving beams include the fourth receiving beam and the fifth receiving beam, the first resource set includes a third set and a fourth set, the fourth receiving beam corresponds to at least one first resource in at least one subset of the third set, and the fifth receiving beam corresponds to at least one first resource in at least one subset of the fourth set.

[0070] The third set and / or the fourth set are at least one of the following: agreed by protocol, configured by a control node, or preconfigured.

[0071] Optionally, at least one subset of the third set and / or at least one subset of the fourth set is at least one of the following: agreed by protocol, configured by a control node, or preconfigured. For example, the receiving beams on the resource subsets with the same number in the third set and the fourth set have a co-location relationship.

[0072] The signal transmission method provided by the embodiment of the application can ensure that the UEs have a unified understanding of the to-be-trained beams and the beam training resources by determining the first resource set by the first terminal and receiving the signal sent by the second terminal on the first resource set.

[0073] As shown in FIG. 4, Figure 4 An embodiment of the application provides a signal transmission method 400, which can be executed by a terminal device, in other words, the method can be executed by software or hardware installed in the terminal device, and the method includes the following steps:

[0074] S402: A first terminal determines a first resource set, and there is a third correspondence relationship between the first resource set and a third resource set.

[0075] This step can adopt the description of the embodiment step S202 or Figure 2 the embodiment step S302, and the repeatable part will not be described herein. Figure 3 the embodiment step S302, and the repeatable part will not be described herein.

[0076] There is a third correspondence relationship between the first resource set and a third resource set. The third resource set is a resource set used by the first terminal to send a signal. That is, for a certain UE, the resource set of the selected transmitted signal is associated with the resource set of the selected received signal. Thus, after the transmission beam of the first terminal to other terminals is determined, the transmission beam of other terminals to the first terminal can also be determined accordingly, and other terminals can determine on which resources to transmit information to the first terminal through beam association.

[0077] Optionally, the third correspondence relationship can include at least one of the following:

[0078] Position correspondence relationship;

[0079] Beam correspondence relationship.

[0080] Optionally, the position correspondence relationship satisfies at least one of the following:

[0081] The position of the third resource set associated with the first resource set is agreed upon, configured by a control node, or pre-configured;

[0082] The position of the third resource set associated with the first resource set is determined by the first terminal and indicated to the relevant terminal;

[0083] The position of the first resource set associated with the third resource set is agreed upon, configured by a control node, or pre-configured;

[0084] The position of the first resource set associated with the third resource set is determined by the first terminal and indicated to the relevant terminal.

[0085] Optionally, the beam correspondence relationship satisfies that the transmission beam on the third resource set and the reception beam on the first resource set have a quasi-co-location relationship.

[0086] Optionally, at least one of the reception resource, the reception resource set, the subset of the reception resource set, the transmission resource, the transmission resource set, and the superset of the transmission resource set that have a quasi-co-location relationship satisfies at least one of the following:

[0087] Agreed upon;

[0088] Configured by a control node;

[0089] Pre-configured;

[0090] Determined by the first terminal and indicated to the relevant terminal.

[0091] S404: Receive the signal sent by the second terminal on the first resource set.

[0092] The present step can adopt Figure 2 The embodiment step S204 or Figure 3 The description of the embodiment step S304 is not repeated here.

[0093] The above describes the signal transmission method according to the embodiment of the present application. The following will be described in combination with Figures 2-4 The signal transmission method according to another embodiment of the present application is described in detail. It can be understood that the interaction between the second terminal and the first terminal described from the second terminal side is the same as or corresponding to the description of the first terminal side in the method shown in the above embodiment, and the relevant description is appropriately omitted to avoid repetition. Figure 5 The signal transmission method according to another embodiment of the present application is described in detail. It can be understood that the interaction between the second terminal and the first terminal described from the second terminal side is the same as or corresponding to the description of the first terminal side in the method shown in the above embodiment, and the relevant description is appropriately omitted to avoid repetition. Figures 2-4 The signal transmission method according to another embodiment of the present application is described in detail. It can be understood that the interaction between the second terminal and the first terminal described from the second terminal side is the same as or corresponding to the description of the first terminal side in the method shown in the above embodiment, and the relevant description is appropriately omitted to avoid repetition.

[0094] Figure 5 The signal transmission method according to another embodiment of the present application is described in detail. It can be understood that the interaction between the second terminal and the first terminal described from the second terminal side is the same as or corresponding to the description of the first terminal side in the method shown in the above embodiment, and the relevant description is appropriately omitted to avoid repetition. Figure 5 As shown in the figure, the method 500 includes:

[0095] S502: The second terminal determines a second resource set.

[0096] The second resource set can be a time domain and / or frequency domain resource set. The resources in the second resource set can be taken as a basic unit of time slot (slot) or other resource units. The resources in the second resource set can be resources of certain channels, such as PSSCH or PSFCH, or resources occupied by certain symbols in a slot.

[0097] In an implementation manner, the second resource set satisfies at least one of the following second conditions:

[0098] The second resources in the second resource set are time domain resources and / or frequency domain resources;

[0099] The size of each second resource in the second resource set is agreed by a protocol;

[0100] The size of each second resource in the second resource set is configured by a control node;

[0101] The size of each second resource in the second resource set is pre-configured;

[0102] The size of each second resource in the second resource set is determined by the second terminal;

[0103] The sizes of the second resources in the second resource set are the same;

[0104] The positions of the second resources in the second resource set are agreed by a protocol;

[0105] The position of each second resource in the second resource set is preconfigured for the control node;

[0106] The position of each second resource in the second resource set is preconfigured;

[0107] The position of each second resource in the second resource set is determined by the second terminal;

[0108] Each second resource in the second resource set is continuous in time. For example, it is continuous in a sidelink slot of a resource pool or in a logical slot.

[0109] Optionally, the at least one second resource set constitutes a resource super set. The resource super set is a periodic resource set, or a resource set in the resource super set is a periodic resource set.

[0110] In another implementation, there is a second correspondence relationship between the second resource set and a first resource set, wherein the first terminal receives the signal on the first resource set. The second correspondence relationship includes at least one of the following:

[0111] The second resource set corresponds to the first resource set;

[0112] The second resource set corresponds to a subset of the first resource set;

[0113] A super set of the second resource set corresponds to the first resource set.

[0114] S504: Transmit the signal on the second resource set.

[0115] The second terminal can transmit a signal, such as a beam training signal, to a proximity UE in each direction on the second resource set. The second resource set contains one or more second resources.

[0116] In an implementation, because the second resource set satisfies at least one of the above-mentioned second conditions, the first terminal and the second terminal can have a unified understanding of the to-be-trained beam and the beam training resource.

[0117] In another implementation, the second terminal transmits the signal on the second resource set. The first terminal receives the signal transmitted by the second terminal on the first resource set. Because there is a first correspondence relationship between the first resource set and the second resource set, the first terminal and the second terminal can have a unified understanding of the to-be-trained beam and the beam training resource.

[0118] The signal transmission method provided by the embodiment of the application can ensure that the UEs have a unified understanding of the to-be-trained beams and beam training resources by determining a second resource set by the second terminal and transmitting a signal on the second resource set.

[0119] Figure 6 The signal transmission method provided by the embodiment of the application can ensure that the UEs have a unified understanding of the to-be-trained beams and beam training resources by determining a second resource set by the second terminal and transmitting a signal on the second resource set. Figure 6 The method 600 includes the following steps.

[0120] S602: The second terminal determines a second resource set.

[0121] In an implementation manner, the resource can be selected randomly or according to a UE identifier (ID).

[0122] In another implementation manner, the sending resource set occupied by a neighboring terminal can be excluded from the resource set, the second resource set is selected from the excluded resource set, the second resource set is formed by randomly selected resources, and the second resource set is selected according to the identifier of the second terminal. In this way, resource collision can be effectively avoided.

[0123] In an implementation manner, after the second resource set is selected, the second resource set is reserved according to the period of the second resource. Then, the sending resource set occupied by a neighboring terminal is excluded from the resource set, and the second resource set is selected from the excluded resource set. In this way, resource collision can be effectively avoided.

[0124] In an implementation manner, before the second terminal transmits a signal on the second resource set, the number and / or frequency of the signal to be transmitted can also be determined. In this way, the number of signals transmitted in the form of the resource set is limited to avoid congestion.

[0125] Specifically, the number and / or frequency of the signal to be transmitted is determined according to at least one of the following,

[0126] a signal transmission quantity limit agreed by a protocol;

[0127] a signal transmission frequency limit agreed by a protocol;

[0128] a configured signal transmission quantity limit;

[0129] a configured signal transmission frequency limit;

[0130] a preconfigured signal transmission quantity limit;

[0131] a preconfigured signal transmission frequency limit;

[0132] The signal sending quantity limit determined according to the congestion degree; wherein the congestion degree comprises: a congestion degree of a resource pool, or a transmission congestion degree of the second resource set;

[0133] The signal sending frequency limit determined according to the congestion degree; wherein the congestion degree comprises: a congestion degree of a resource pool, or a transmission congestion degree of the second resource set.

[0134] S604: sending a signal on the second resource set through a sending beam.

[0135] Wherein, the sending beam or sending beam mode corresponding to the resource on the second resource set is preset or determined by the second terminal. The sending beam mode is for example a beam scanning mode.

[0136] In an implementation manner, the sending beam or sending beam mode being preset comprises at least one of the following: being agreed by a protocol, being configured by a control node, or being preconfigured.

[0137] In an implementation manner, there is a quasi-co-location relationship between the first sending beam and the second sending beam, and the sending beams corresponding to the quasi-co-location relationship are same beams. Wherein, the sending beams comprise the first sending beam and the second sending beam, the second resource set comprises a first set and a second set, the first sending beam corresponds to at least one first resource in the first set, and the second sending beam corresponds to at least one second resource in the second set. For example, there is a quasi-co-location relationship between all resource sets; there is a quasi-co-location relationship between every N resource sets.

[0138] In an implementation manner, in the case that there is a resource super set, there is a quasi-co-location relationship between each resource set in the same resource super set.

[0139] In an implementation manner, in the case that there is a resource super set, there is a quasi-co-location relationship between resource sets of different resource super sets. For example, there is a quasi-co-location relationship between sending beams of all resource sets of all resource super sets; there is a quasi-co-location relationship between sending beams of resource sets of every N resource super sets.

[0140] In an implementation manner, the resource corresponding to the quasi-co-location relationship is at least one of the following: being agreed by a protocol, being configured by a control node, or being preconfigured. For example, the sending beams on the resources with same numbers in the resource set have a co-location relationship.

[0142] S702: The second terminal determines a second resource set, and a fourth correspondence relationship exists between the second resource set and a fourth resource set.

[0143] This step can adopt Figure 5 The embodiment step S502 or Figure 7 The description of the embodiment step S702 will not be repeated for repeatable parts.

[0144] In an implementation manner, the fourth correspondence relationship exists between the second resource set and a fourth resource set, and the fourth resource set is a resource set used by the second terminal when receiving a signal.

[0145] In an implementation manner, the fourth correspondence relationship includes at least one of the following:

[0146] A position correspondence relationship;

[0147] A beam correspondence relationship.
