For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (bs), a home base station, an Access Point (AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (transmission point, TP), or a transmission reception point (transmission and reception point, TRP), etc., may also be a gNB in an NR system, or may also be a component or a part of a device that forms a base station, etc. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device configuration adopted by the network device are not limited.

When the terminal reserves the resources, the terminal sends the indication information to indicate the reserved resources, and after other terminals hear the indication information or sense that a certain resource is being used or reserved, the other terminals do not use or reserve the resource being used or reserved.

Currently, resource reservation in sidelink communication is based on omni-direction, i.e. the beam direction is not considered in resource reservation. How to implement beam-based resource reservation is thus being studied.

Based on this, the embodiment of the disclosure provides a method for sidelink communication, where a device performing sidelink communication sends indication information, where the indication information is used to indicate reserved resources and beam information corresponding to the reserved resources, and another device performing sidelink communication with the device sending the indication information can determine resource reservation based on a beam based on the indication information, so as to improve performance of sidelink based on beam transmission.

In one sidelink communication method provided by the embodiments of the present disclosure, the indication information is used to indicate a beam used for transmitting a first sidelink channel and/or a signal, and a beam used for transmitting a second sidelink channel and/or a signal.

In the sidelink communication method provided by the embodiment of the disclosure, when the indication information is used for indicating the beam used for transmitting the first sidelink channel and/or the signal, the beam used for transmitting the second sidelink channel and/or the signal is determined based on the beam used for transmitting the first sidelink channel and/or the signal indicated by the indication information. The beam used to transmit the second sidelink channel and/or signal is determined to be the same as the beam used to transmit the first sidelink channel and/or signal, e.g., based on the default rule and the beam indicated by the indication information.

In the above embodiment, the first sidelink channel and/or signal is a sidelink channel and/or signal transmitted on a frequency domain resource configuration and/or a time domain resource configuration indicated by sidelink control information (Sidelink Control Information, SCI) where the indication information is located, and the second sidelink channel and/or signal is a sidelink channel and/or signal transmitted on a reserved resource.

Wherein the indication information sent by the first device is used for indicating a set of beam information used for transmission of the first side link channel and/or signal and/or transmission of the second side link channel and/or signal.

For example, the SCI where the indication information is located is SCI 1-A, the SCI 1-A indicates the frequency domain resource configuration and/or the time domain resource configuration corresponding to the first side link channel and/or the signal transmission, and the reserved resource is in SCI 1-A or SCI2-C scheduled by SCI 1-A, and then the indication field of the set of beam information can be carried in SCI 1-A or SCI2-C scheduled by SCI 1-A. I.e. the first side link channel and/or signal and the second side link channel and/or signal correspond to the same beam information.

In other embodiments of a sidelink communication method provided by the embodiments of the present disclosure, the indication information is used to indicate at least two sets of beam information, where the at least two sets of beam information include first beam information and/or second beam information.

In other embodiments of a sidelink communication method provided by the embodiments of the present disclosure, the indication information is used to indicate a set of third beam information, where the set of third beam information is used to indicate a beam of a second sidelink channel and/or a signal transmitted on a reserved resource of at least one time unit. That is, in the embodiment of the present disclosure, beam information corresponding to reserved resources on all time units is the same.

In some embodiments, the first device may reserve resources over multiple time units. The time unit may be a slot (slot), or a mini-slot (mini-slot). mini-slots are relative to slots as time units. When scheduling is performed by taking slot as a time unit, the occupied number of symbols is 3 minimum; the number of symbols occupied by mini-slots may be 1 or 2. And one slot may include a plurality of scheduled mini-slots of time units. One mini-slot may also occupy the symbols of two adjacent slots.

In other embodiments of a sidelink communication method provided in the embodiments of the present disclosure, the indication information is used to indicate at least two sets of fourth beam information, and the at least two sets of fourth beam information are used to indicate beams of a second sidelink channel and/or a signal transmitted on reserved resources of at least two time units.

In embodiments of the present disclosure, reserved resources on different time units may correspond to different fourth beam information. Wherein, the reserved resources of different time units can be in one-to-one correspondence with the fourth beam information; or the reserved resources of a plurality of time units correspond to a set of fourth beam information. The corresponding relation between the reserved resources of different time units and the fourth beam information is determined based on a default rule or indicated in the indication information explicitly.

In the sidelink communication method provided by the embodiment of the disclosure, the number of time units included in the reserved resources is M, the indication information includes N sets of fourth beam information, M is a positive integer, and N is a positive integer greater than or equal to 2.

In some embodiments, the N sets of fourth beam information are in one-to-one correspondence with side link channels and/or signals transmitted on reserved resources of the M time units; and/or, the N sets of fourth wave beam information are in one-to-one correspondence with the side chain channels and/or signals transmitted on the reserved resources of the N sets of time units, wherein the M time units are divided into N sets, and each set comprises time units which are continuous or discontinuous.

In one embodiment, in response to m=n, N sets of fourth beam information correspond one-to-one with side link channels and/or signals transmitted on reserved resources of M time units.

For example, the number of time units included in the reserved resource is m=4, and at least two sets of beam information include n=4 sets of fourth beam information, so that the 4 sets of fourth beam information are in one-to-one correspondence with side link channels and/or signals transmitted on the reserved resource of 4 time units.

In another embodiment, the N sets of fourth beam information correspond one-to-one with side link channels and/or signals transmitted on reserved resources of the N sets of time units in response to M > N.

For example, the number of time units included in the reserved resource is m=8, and at least two sets of beam information include n=4 sets of fourth beam information, where the 4 sets of fourth beam information are in one-to-one correspondence with side link channels and/or signals transmitted on the reserved resource of the 4 sets of time units, that is, each set of fourth beam information is in one-to-one correspondence with side link channels and/or signals transmitted on the reserved resource of 2 time units. When the 8 time units are divided into 4 groups, each group includes time units that are continuous or discontinuous. For example, each group comprises consecutive time units, i.e. the first group of time units comprises a first and a second time unit, the second group of time units comprises a third and a fourth time unit, the third group of time units comprises a fifth and a sixth time unit, and the fourth group of time units comprises a seventh and an eighth time unit. For example, each group may include time cells that are discontinuous, i.e., a first group of time cells includes a first and fifth time cell, a second group of time cells includes a second and sixth time cell, a third group of time cells includes a third and seventh time cell, and a fourth group of time cells includes a fourth and eighth time cell.

In the sidelink communication method provided by the embodiment of the disclosure, the beam information of the first sidelink channel and/or the signal transmission is determined based on the time interval between the indication information and the first sidelink channel and/or the signal. As shown in fig. 3, the method comprises the following steps:

in step S21, beam information for the first side link channel and/or signal transmission is determined based on the time interval between the indication information and the first side link channel and/or signal.

The indication information here is indication information including first beam information corresponding to the first sidelink channel and/or the signal.

In some embodiments, when a time interval between the indication information and the first sidelink channel and/or signal is greater than or equal to a time interval threshold, beam information for transmission of the first sidelink channel and/or signal is determined based on the indication information; and/or, when the time interval between the indication information and the first side link channel and/or signal is less than the time interval threshold, the beam information of the transmission of the first side link channel and/or signal is determined based on a default rule.

In one embodiment, beam information for transmission of the first side link channel and/or signal is determined based on the indication information in response to a time interval between the indication information and the first side link channel and/or signal being greater than or equal to a time interval threshold.

In the embodiments of the present disclosure, since the time interval between the indication information and the first side link channel and/or signal is greater than or equal to the time interval threshold, there is enough time to decode the indication information to determine beam information for transmission of the first side link channel and/or signal based on the indication information.

In another embodiment, beam information for transmission of the first side link channel and/or signal is determined based on a default rule in response to a time interval between the indication information and the first side link channel and/or signal being less than a time interval threshold.

In the disclosed embodiments, since the time interval between the indication information and the first side link channel and/or signal is less than the time interval threshold, the time interval is too small to decode the beam information included in the indication information, the beam information for transmission of the first side link channel and/or signal is determined based on a default rule.

In the sidelink communication method provided in the embodiment of the present disclosure, before sending the indication information, the first device needs to determine whether the indication information includes beam information. As shown in fig. 4, the method comprises the following steps:

in step S31, it is determined whether the indication information includes beam information corresponding to the reserved resources based on the configuration information.

In one embodiment, the configuration information is transmitted by the second device. Wherein the second device may be a second terminal or a network device.

In some embodiments, the first device determines, based on the configuration information, that the indication information includes beam information corresponding to the reserved resource, and then sends the indication information, where the indication information is used to indicate the reserved resource and the beam information corresponding to the reserved resource.

In the embodiment of the disclosure, when the first device determines, based on the configuration information, that the indication information includes beam information corresponding to the reserved resources, the indication information for indicating the reserved resources and the beam information corresponding to the reserved resources is sent, so that the second device can determine, based on the indication information, the reservation of the resources based on the beams, and improve performance of the sidelink based on beam transmission.

Based on the same conception, the embodiment of the disclosure also provides a sidelink communication method applied to the second device.

Fig. 5 is a flowchart illustrating a sidelink communication method, as shown in fig. 5, performed by a second device, according to an exemplary embodiment, the method comprising the following steps.

In step S41, indication information is received, where the indication information is used to indicate reserved resources and beam information corresponding to the reserved resources.

In the embodiment of the disclosure, the second device receives the indication information sent by the first device, where the indication information is used to indicate the reserved resource and the beam information corresponding to the reserved resource, so that the second device can determine the resource reservation based on the beam based on the indication information, and improve the performance of the sidelink based on the beam transmission.

In other embodiments of a sidelink communication method provided by the embodiments of the present disclosure, the indication information is used to indicate a set of third beam information, where the set of third beam information is used to indicate a beam of a second sidelink channel and/or a signal transmitted on a reserved resource of at least one time unit.

That is, in the embodiment of the present disclosure, beam information corresponding to reserved resources on all time units is the same.

That is, in embodiments of the present disclosure, reserved resources on different time units may correspond to different fourth beam information. Wherein, the reserved resources of different time units can be in one-to-one correspondence with the fourth beam information; or the reserved resources of a plurality of time units correspond to a set of fourth beam information. The corresponding relation between the reserved resources of different time units and the fourth beam information is determined based on a default rule or indicated in the indication information explicitly.

In the sidelink communication method provided by the embodiment of the disclosure, the beam information of the first sidelink channel and/or the signal transmission is determined based on the time interval between the indication information and the first sidelink channel and/or the signal.

In some embodiments, when the time interval between the indication information and the first sidelink channel and/or signal is greater than or equal to a time interval threshold, determining beam information for transmission of the first sidelink channel and/or signal based on the indication information; and/or determining beam information for transmission of the first side link channel and/or signal based on a default rule when a time interval between the indication information and the first side link channel and/or signal is less than a time interval threshold.

In one embodiment, the beam information of the transmission of the first side link channel and/or signal is determined based on the indication information in response to a time interval between the indication information and the first side link channel and/or signal being greater than or equal to a time interval threshold.

In an embodiment of the present disclosure, since the time interval between the indication information and the first sidelink channel and/or signal is greater than or equal to the time interval threshold, there is enough time to decode the indication information such that the beam information of the transmission of the first sidelink channel and/or signal is determined based on the indication information.
