1. A symbol reservation method, applied to a first node, comprising:
determining a first element set; and
sending request information, wherein the request information is used for requesting to reserve or not to reserve a guard symbol at a transition in a case where a second unit of the first node performs transmission or reception on elements in the first element set, and the first element set is used to indicate that the first node requests a second node to perform a guard symbol reservation mechanism in a case where the first node transmits at least one of a signal or a channel,
wherein the first element set is an empty set, or the first element set comprises one of the following:
a first set;
a second set, which is a subset of a first set;
a third set, which is one set of a set group;
a set composed of elements in a first set other than elements in a second set which is a subset of the first set; or
a set composed of elements in a set group other than elements in a third set which is one set of the set group,
wherein the transition comprises:
a transition between an operation of a first unit of the first node and an operation of the second unit of the first node; or
a transition between an operation of the second unit on a first attribute resource and an operation of the second unit on a second attribute resource; or
a transition between a first attribute resource corresponding to the second unit and a second attribute resource corresponding to the second unit, and
wherein the first attribute resource comprises at least one of the following: a not available (NA) resource, a not indicated available (NIA) soft resource, a time unit where an NA resource is located, or a time unit where an NIA soft resource is located; and
the second attribute resource comprises at least one of the following: a resource occupied by the elements in the first element set, an NA resource or an NIA soft resource occupied by the elements in the first element set, a time unit where a resource occupied by the elements in the first element set is located, or a time unit where an NA resource or an NIA soft resource occupied by the elements in the first element set is located.
