Publication number: 20240137958Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.Type: ApplicationFiled: April 28, 2021Publication date: April 25, 2024Inventors: Yiqing CAO, Peter GAAL, Timo Ville VINTOLA, Alberto RICO ALVARINO, Kazuki TAKEDA, Wanshi CHEN, Bin HAN, Yan LI, Zhimin DU

Publication number: 20240057164Abstract: This application relates to the field of wireless communication, in particular, to a beacon frame transmission method in an EMLSR mode, and is applied to a wireless local area network supporting the 802.11be standard. A TXOP holder sends a first frame before a first delay prior to a next TBTT, where the first frame indicates TXOP termination on a first link. The first delay is used by an EMLSR non-AP MLD to change a spatial stream on a second link to a state supporting beacon frame reception on the second link. The non-AP MLD changes, within the first delay after the TXOP termination on the first link, a spatial stream on the second link to supporting successful beacon frame reception on the second link, and receives a beacon frame by using a spatial stream currently supported on the second link at the next TBTT.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Inventors: Yiqing LI, Yuchen GUO, Yunbo LI, Guogang HUANG, Ming GAN
