US-12621711-B2 - Discard timer for protocol data unit communications

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first discard timer value associated with a radio bearer. The UE may receive a multiplier value that is associated with a characteristic of a protocol data unit or a protocol data unit set to be transmitted via the radio bearer. The UE may initiate a discard timer for the protocol data unit or the protocol data unit set, the discard timer having a second discard timer value that corresponds to the first discard timer value multiplied by the multiplier value. Numerous other aspects are described.

Description

CROSS-REFERENCE TO RELATED APPLICATION This patent application claims priority to U.S. Provisional Patent Application No. 63/490,732, filed on Mar. 16, 2023, entitled “DISCARD TIMER FOR PROTOCOL DATA UNIT COMMUNICATIONS,” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is incorporated by reference into this patent application. FIELD OF THE DISCLOSURE Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for a discard timer for protocol data unit communications. DESCRIPTION OF RELATED ART Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (for example, bandwidth, transmit power, etc.). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the network node to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and/or a wireless personal area network (WPAN) link, among other examples). These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, or global level. New Radio (NR), which also may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency-division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

The method may include receiving a first discard timer value associated with a radio bearer. The method may include receiving a multiplier value that is associated with a characteristic of a protocol data unit or a protocol data unit set to be transmitted via the radio bearer. The method may include initiating a discard timer for the protocol data unit or the protocol data unit set, the discard timer having a second discard timer value that corresponds to the first discard timer value multiplied by the multiplier value. Some aspects described herein relate to a method of wireless communication performed by a network node. The method may include transmitting a first discard timer value associated with a radio bearer. The method may include transmitting a multiplier value that is associated with a characteristic of a protocol data unit or a protocol data unit set to be transmitted via the radio bearer. The method may include initiating a discard timer for the protocol data unit or the protocol data unit set, the discard timer having a second discard timer value that corresponds to the first discard timer value multiplied by the multiplier value. Some aspects described herein relate to an apparatus for wireless communication at a UE. The apparatus may include a memory and one or more processors coupled to the memory. The one or more processors may be configured to receive a first discard timer value associated with a radio bearer. The one or more processors may be configured to receive a multiplier value that is associated with a characteristic of a protocol data unit or a protocol data unit set to be transmitted via the radio bearer.
