Patent number: 11943161Abstract: A method and a device in a User Equipment and a base station are provided. The UE receives first information and monitors a first signaling in M Resource Element (RE) sets. The first information determines the M RE sets. The UE assumes that P modulation symbol groups are one-to-one mapped to P RE sets of the M RE sets. One blind detection for the first signaling is performed on the P RE sets. Modulation symbols obtained by modulating the bits in a first bit sequence constitute a first modulation symbol set sequentially. The bits in the first bit sequence are sequentially arranged according to an output of a channel encoder. The first modulation symbol set is successively divided into the P modulation symbol groups, each consisting of X modulation symbols.Type: GrantFiled: January 8, 2021Date of Patent: March 26, 2024Assignee: SHANGHAI QIYU COMMUNICATION TECHNOLOGY SERVICE CENTERInventor: Xiaobo Zhang

Patent number: 11848892Abstract: The present disclosure provides a method and a device in wireless transmission. A User Equipment (UE) receives a first radio signal, then detects a low-latency signaling in L1 time intervals respectively, and transmits first HARQ-ACK information. The low-latency signaling includes a first field, and the first field is used for determining a relationship between a low-latency HARQ-ACK bit group and a first HARQ-ACK bit group. The first HARQ-ACK information includes part or all of HARQ-ACK bits in the first HARQ-ACK bit group. Through the design of the first field, the information in the first HARQ-ACK bit group can be put into the low-latency HARQ-ACK bit group to transmit, thereby optimizing the transmission of the Uplink Control Information (UCI) for HARQ-ACK, reducing the resource overhead and power overhead for the transmission of the UCI, and improving the overall system performance and spectrum efficiency.Type: GrantFiled: March 16, 2022Date of Patent: December 19, 2023Assignee: SHANGHAI QIYU COMMUNICATION TECHNOLOGY SERVICE CENTERInventor: Xiaobo Zhang

Publication number: 20230170947Abstract: A method and device for power adjustment in a user equipment and a base station are disclosed in the present disclosure. The user equipment receives first information which is used to trigger a first operation, and then receives K piece(s) of target information and transmits a first wireless signal. A transmission power value of the first wireless signal is a first power value; the first power value is irrelevant to all piece(s) of target information received prior to triggering the first operation. The K piece(s) of target information is(are) received after triggering the first operation. The sum of K power offset value(s) is used to determine the first power value. The K power offset value(s) are respectively indicated by the K piece(s) of target information.Type: ApplicationFiled: January 29, 2023Publication date: June 1, 2023Applicant: SHANGHAI QIYU COMMUNICATION TECHNOLOGY SERVICE CENTERInventors: Qi JIANG, Xiaobo ZHANG
