Description

Resource determination method, communication node and storage medium Technical Field

[0001] The present application relates to the field of communication technology, for example, to a resource determination method, a communication node, and a medium. Background Art

[0002] In a sidelink communication system, when services need to be transmitted between user equipment (UE), they bypass the network, bypassing the cellular link between the UE and the base station. Instead, the services are transmitted directly from the source UE to the target UE via sidelink. Sidelink communication not only conserves wireless spectrum resources but also reduces data transmission pressure on the core network. This reduces system resource usage, increases cellular system spectrum efficiency, reduces communication latency, and significantly reduces network operating costs.

[0003] In the determination of the Physical Sidelink Feedback Channel (PSFCH) resources in the sidelink, only the Intelligent Transport System (ITS) spectrum and the authorized spectrum allocated to the network operator are considered. In the case where the sidelink uses unlicensed spectrum, only the channel that successfully listens before talks (LBT) can be transmitted. The so-called LBT means that the communication node needs to compete for resources. Only when the competition for time-frequency resources is successful can the communication node transmit information on the time-frequency resources. More specifically, in the LBT mechanism, the communication node performs a channel access process (monitors whether the channel is idle) before transmitting information. Only when the channel is idle and meets certain requirements can the communication node transmit information. In the case where the sidelink uses unlicensed spectrum, there is currently no method for PSFCH selection.

[0136] In one embodiment, a lower priority value indicates a higher priority.

[0137] In one embodiment, the user equipment transmits information on at least one common interlace in addition to the dedicated PSFCH transmission.

[0138] In one embodiment, information transmitted on the common interlace is used for channel occupancy, and / or information similar to a PSFCH is transmitted on the common interlace. This PSFCH-like information is not a dedicated PSFCH, that is, this PSFCH-like information is not used to indicate HARQ-ACK information or collision indication information. And / or information similar to a PSFCH is transmitted on the common interlace and is obtained by copying a dedicated PSFCH.

[0139] In one embodiment, the time domain of the common interlace overlaps with the time domain of the dedicated PSFCH resources, and the common interlace may also be referred to as PSFCH common interlace. Transmission on the common interlace may be referred to as common interlace transmission.

[0140] In one embodiment, the user equipment selects at least one common interlace transmission before selecting dedicated PSFCH transmissions. It can also be understood that the common interlace transmission has a higher priority than all PSFCH transmissions.

[0141] In one embodiment, the total number of resource blocks used to transmit information in the common interlace and the resource blocks corresponding to the target dedicated PSFCH does not exceed a first threshold corresponding to the resource block transmission capacity. The first threshold represents a simultaneous transmission capability of a user equipment. This capability can be understood as representing a capability number. For a user equipment with a capability number N, transmitting one common interlace transmission and at least one dedicated PSFCH transmission, the total number of RBs used does not exceed the first threshold N.

[0142] In one embodiment, the sum of the total number of resource blocks for information transmission on the common interlace and the resource blocks corresponding to the target dedicated PSFCH and the number of resource blocks corresponding to a single dedicated PSFCH exceeds a first threshold N.

[0143] In one embodiment, the first threshold is a value configured or pre-configured by higher layer signaling.

[0144] In one embodiment, the value of the first threshold is determined based on the fact that the sum of the power corresponding to the common interlace and the power corresponding to the target dedicated PSFCH does not exceed a set threshold.

[0145] In one embodiment, the number of resource blocks corresponding to the target dedicated PSFCH does not exceed a second threshold corresponding to the resource block transmission capability. The second threshold represents the capability of the user equipment to support the total number of RBs for PSFCH transmissions when simultaneously transmitting dedicated PSFCH transmissions. This means that a user equipment with a capability of N can, in addition to transmitting a common interlace transmission, also transmit dedicated PSFCH transmissions, with the total number of RBs in these dedicated PSFCH transmissions not exceeding the second threshold N.

[0146] In one embodiment, the sum of the total number of resource blocks corresponding to the target dedicated PSFCH and the number of resource blocks corresponding to a single dedicated PSFCH exceeds a second threshold N.

[0147] In one embodiment, the second threshold is a value configured or pre-configured by higher layer signaling.

[0148] In one embodiment, the value of the second threshold is determined based on the fact that the sum of the powers corresponding to the target dedicated PSFCHs does not exceed a set threshold.

[0149] In one embodiment, after the user equipment selects common interleaved transmission and PSFCH transmission, it may optionally remove part of the RBs corresponding to the common interleaved transmission, and transmit on the remaining RBs corresponding to the common interleaved transmission, as well as the selected dedicated PSFCH transmission.

[0150] In one embodiment, for a PSFCH opportunity, the operations performed by the user equipment include:

[0151] Dedicated PSFCH transmissions are selected in ascending order of priority value, where one dedicated PSFCH belongs to one interlace; at least one RB from among the RBs contained in at least one common interlace is selected; and at least one dedicated PSFCH transmission is dropped from the selected dedicated PSFCH transmissions.

[0152] In one embodiment, at least one RB from among the RBs included in at least one common interlace is selected, and the selection principle includes:

[0153] For an RB in the common interlace, the RB and any RB in the PSFCH resources corresponding to any PSFCH transmission in the dedicated PSFCH transmissions selected by the user equipment are not located in the same 1 MHz bandwidth.

[0154] In one embodiment, a common interlace transmission corresponds to a transmission on a selected RB in a common interlace.

[0155] In one embodiment, at least one dedicated PSFCH transmission is dropped from the selected dedicated PSFCH transmissions, including at least one common interlace transmission and the remaining dedicated PSFCH transmissions, wherein the total number of RBs corresponding to these transmissions does not exceed a fourth threshold.

[0156] In one embodiment, the fourth threshold represents a simultaneous transmission capability of a user equipment. This capability can be understood as representing a number. A user equipment with a capability of N transmits at least one common interlace transmission and the remaining dedicated PSFCH transmissions, and the total number of RBs used does not exceed the fourth threshold N.

[0157] In one embodiment, the sum of the total number of RBs corresponding to at least one common interlace transmission and the remaining dedicated PSFCH transmissions, and the number of RBs corresponding to a single dedicated PSFCH transmission exceeds a fourth threshold.

[0158] In one embodiment, the fourth threshold is a value configured or pre-configured by higher layer signaling.

[0159] In one embodiment, the value of the fourth threshold is determined based on the sum of the power corresponding to at least one common interlace and the power corresponding to the remaining dedicated PSFCH transmissions not exceeding a set threshold.

[0160] In one embodiment, the total number of resource blocks corresponding to the dedicated PSFCHs remaining in the target dedicated PSFCH does not exceed a third threshold.

[0161] In one embodiment, the sum of the total number of resource blocks corresponding to the dedicated PSFCHs remaining in the target dedicated PSFCH and the number of resource blocks corresponding to a single dedicated PSFCH exceeds a third threshold.

[0162] In one embodiment, the third threshold is a value configured or pre-configured by higher layer signaling.

[0163] In one embodiment, the value of the third threshold is determined based on the fact that the sum of powers corresponding to at least one dedicated PSFCH transmission does not exceed a set threshold.
