CN-122029773-A - Uplink repetition frequency hopping in hybrid sub-band full duplex and non-sub-band full duplex time slots

Abstract

Methods, systems, and devices for wireless communications are described. The described technology provides for a User Equipment (UE) to selectively transmit uplink repetitions configured with intra-slot frequency hopping during a slot that includes both sub-band full duplex (SBFD) symbols and non-SBFD symbols. For example, the UE may receive a control message that schedules repetition of an uplink message and indicates a configuration for intra-slot frequency hopping of the repetition. In some cases, the UE may selectively transmit repetitions during a mixed-symbol slot based on whether the slot is deemed available, an alignment of a boundary between SBFD and non-SBFD symbols of the mixed-symbol slot with time resources for portions of the repetition, transmission parameters associated with SBFD and non-SBFD symbols, or any combination thereof.

Description

Uplink repetition frequency hopping in hybrid sub-band full duplex and non-sub-band full duplex time slots Cross reference This patent application claims priority from U.S. patent application Ser. No. 18/830371 entitled "uplink repetition frequency hopping in Mixed sub-band full Duplex and non-sub-band full Duplex timeslots" filed by ABDELGHAFFAR et al at 10 of 2024 and U.S. patent application Ser. No. 63/586,095 entitled "uplink repetition frequency hopping in Mixed sub-band full Duplex and non-sub-band full Duplex timeslots filed by ABDELGHAFFAR et al at 28 of 2023, which are assigned to the assignee of the present application and expressly incorporated herein by reference. Technical Field The following relates to wireless communications, including uplink repetition frequency hopping in hybrid sub-band full duplex (SBFD) and non-SBFD time slots. Background Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be able to support communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems, such as Long Term Evolution (LTE) systems, LTE-advanced (LTE-a) systems, or LTE-a Pro systems, and fifth generation (5G) systems, which may be referred to as New Radio (NR) systems. These systems may employ techniques such as Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal FDMA (OFDMA), or discrete fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communication system may include one or more base stations, each supporting wireless communications for communication devices, which may be referred to as User Equipment (UEs). Disclosure of Invention The described technology relates to improved methods, systems, devices, and apparatus for uplink repetition frequency hopping in supporting mixed sub-band full duplex and non-sub-band full duplex timeslots. For example, the described techniques provide for a User Equipment (UE) to selectively transmit uplink repetitions configured with intra-slot frequency hopping during a hybrid symbol slot (e.g., a slot that includes both sub-band full duplex (SBFD) symbols and non-SBFD symbols). Such a slot may include a first set of symbols associated with SBFD communications (e.g., associated with one or more downlink subbands and one or more uplink subbands) and a second set of symbols associated with unidirectional communications (e.g., bandwidth or portion of bandwidth dedicated to uplink communications or downlink communications). In some cases, the UE may send an uplink message (e.g., to a network device) and one or more repetitions of the uplink message. Additionally, the UE may receive a configuration of intra-slot frequency hopping for each transmission of the uplink message. For example, each repetition of an uplink message may include one or more frequency hops (e.g., frequency separation between portions of the repetition) within a time slot. In some cases, the UE may selectively transmit such repetitions during the hybrid-symbol time slot based on whether the time slot is deemed to be available (e.g., based on a counting perspective of the UE), an alignment of a boundary between SBFD and non-SBFD symbols of the hybrid-symbol time slot with a time-domain position of a frequency hop of the repetition, transmission parameters associated with SBFD and non-SBFD symbols, or any combination thereof. A method for wireless communication by a UE is described. The method may include receiving a control message including scheduling information for a plurality of repeated sets of uplink messages transmitted by the UE, the scheduling information indicating an intra-slot frequency hopping configuration for each of the plurality of repeated sets, and selectively transmitting one or more portions of a repetition of the plurality of repeated sets during a time slot including a first set of symbols associated with SBFD communications and a second set of symbols associated with uplink communications based on one or both of availability of the time slot and a boundary between the first set of symbols and the second set of symbols relative to time resources associated with the one or more portions of the repetition, wherein the time resources are based on one or more frequency hops indicated by the intra-slot frequency hopping configuration. A UE for wireless communication is described. The UE may include one or more memories storing processor-executable code and one or more processors coupled with the one or more memories. The one or more processors may be operable, individually or collectively, to execute the code to cause the UE to receive a control message including scheduling information for a plural
