Patent number: 11240831Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use one or more antenna subarrays to perform a scheduling request (SR) operation with one or more corresponding transmission reception points (TRPs) while operating in a connected discontinuous reception mode. In some implementations, the UE may receive a configuration indicating a set of its antenna subarrays and a corresponding set of the TRPs with which to perform the SR operation. Based on this configuration, the UE may transmit an SR to the set of TRPs using the set of its antenna subarrays, receive an uplink grant from at least one TRP of the set of TRPs, and transmit uplink data to the at least one TRP. Additionally or alternatively, the UE may determine the sets of antenna elements and TRPs for the SR operation autonomously and transmit an indication of this determination when transmitting the SR.Type: GrantFiled: February 10, 2020Date of Patent: February 1, 2022Assignee: QUALCOMM IncorporatedInventors: Sungwoo Park, Mostafa Khoshnevisan, Xiaoxia Zhang, Tao Luo, Jing Sun, Wooseok Nam

Patent number: 11240792Abstract: Embodiments of this application disclose a message transmission method and apparatus, a terminal, and a base station. In the method, a symbol or symbol group may be used as a granularity to select a plurality of symbols or symbol groups from one or more slots and then allocate the plurality of symbols or symbol groups to a same terminal for transmitting data. The plurality of symbols or symbol groups may be used for uplink data scheduling or may be used for downlink data scheduling. Therefore, a slot resource is allocated at a small granularity, so that a time domain resource is more flexibly allocated, and the slot resource is more fully utilized. This helps improve message transmission efficiency, thereby expanding a coverage area.Type: GrantFiled: October 28, 2019Date of Patent: February 1, 2022Assignee: Huawei Technologies Co., Ltd.Inventors: Xingwei Zhang, Chao Li, Jie Shi, Zhe Liu
