Abstract

Various aspects of the present disclosure relate to managing (e.g., configuring, determining, establishing, selecting, controlling, and the like) transmission window or reception window for wireless communications. One or more of a network equipment (NE) (e.g., a base station) or a user equipment (UE) may be configured to, capable of, or operable to transmit a first signaling that indicates a transmitter-based (Tx-based) report associated with radio link control (RLC) of the NE or the UE based at least in part on one or more triggers, one or more conditions, or a combination thereof. One or more of the NE or the UE may be configured to, capable of, or operable to receive a second signaling that indicates a receiver-based (Rx-based) report associated with the RLC of the NE or the UE and, based at least in part on the received Rx-based report, update a transmission window.

Description

TECHNICAL FIELD The present disclosure relates to wireless communications, and more specifically to managing (e.g., configuring, determining, establishing, selecting, controlling, and the like) transmission window or reception window for wireless communications. BACKGROUND A wireless communications system may include one or multiple network communication devices, which may be otherwise knowns as network equipment (NE), supporting wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE), or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers, or the like). Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)). SUMMARY An article “a” before an element is unrestricted and understood to refer to “at least one” of those elements or “one or more” of those elements. The terms “a,” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” or “one or both of”) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). By way of another example, a list of at least one of A; B; or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on”. Further, as used herein, including in the claims, a “set” may include one or more elements. An apparatus for wireless communication is described. The apparatus may be one or more of a NE (e.g., a base station) or a UE. The apparatus may be configured to, capable of, or operable to perform one or more operations as described herein. For example, the apparatus may be configured to, capable of, or operable to transmit a first signaling that indicates a transmitter-based (Tx-based) report associated with radio link control (RLC) of the apparatus based at least in part on one or more triggers, one or more conditions, or a combination thereof; receive a second signaling that indicates a receiver-based (Rx-based) report associated with the RLC of the apparatus; and update, based at least in part on the received Rx-based report, a transmission window of the apparatus. A processor for wireless communication is described. The processor may be included in (e.g., be a component of) one or more of a NE (e.g., a base station) or a UE. The processor may be configured to, capable of, or operable to perform one or more operations as described herein. For example, the processor may be configured to, capable of, or operable to transmit a first signaling that indicates a Tx-based report associated with RLC of an apparatus based at least in part on one or more triggers, one or more conditions, or a combination thereof; receive a second signaling that indicates a Rx-based report associated with the RLC of the apparatus; and update, based at least in part on the received Rx-based report, a transmission window of the apparatus. A method performed or performable by an apparatus for wireless communication is described. The apparatus may be one or more of a NE (e.g., a base station) or a UE. The method performed or performable may include transmitting a first signaling that indicates a Tx-based report associated with RLC of an apparatus based at least in part on one or more triggers, one or more conditions, or a combination thereof; receiving a second signaling that indicates a Rx-based report associated with the RLC of the apparatus; and updating, based at least in part on the received Rx-based report, a transmission window of the apparatus. In some implementations of the apparatus, processor, and method described herein, the Tx-based report includes information that identifies invalid (e.g., expired, outdated) RLC packet data units (PDUs). In some implementations of the apparatus, processor, and method described herein, the Tx-based report
