Patent number: 11997050Abstract: The techniques described herein relate to methods, apparatus, and computer readable media configured to schedule individual orthogonal frequency-division multiple access (OFDMA) resources on an upstream channel to serve a data transmission request from a downstream device. A schedule for a set of available resources on the upstream channel to serve the data transmission request is generated, based on a dynamic bit loading profile, including generating data indicative of a first bit loading profile for a first set of resources from the set of available resources for a first burst, and data indicative of a second bit loading profile for a second set of resources from the set of available resources for a second burst. The schedule is transmitted to a downstream device, such that the downstream device is configured to encode the first burst using the first bit loading profile and the second burst using the second bit loading profile.Type: GrantFiled: June 14, 2023Date of Patent: May 28, 2024Assignee: Casa Systems, Inc.Inventors: Hongbiao Zhang, Chain Lee, Yanbo Yuan, Tao Yu, Weidong Chen

Patent number: 11974321Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access (RACH) procedure based on a selected synchronization signal block (SSB). During this RACH procedure, a base station may transmit physical downlink control channel (PDCCH) messages for UE RACH message handling. To receive PDCCH signaling for RACH Messages 2, 3, or 4 (Msg 2/3/4), the UE may identify a set of time resources used by the base station for transmitting SSBs that are not quasi-co-located (QCL) with the selected SSB. The UE may identify a Msg 2/3/4 search space that does not overlap with this identified set of resources, and may monitor this identified search space. The search space may correspond to a modified remaining minimum system information (RMSI) search space indicated by the base station, or a valid RMSI search space not indicated by the base station.Type: GrantFiled: February 22, 2019Date of Patent: April 30, 2024Assignee: QUALCOMM IncorporatedInventors: Muhammad Nazmul Islam, Bilal Sadiq, Navid Abedini, Heechoon Lee, Tao Luo

Patent number: 11962399Abstract: Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.Type: GrantFiled: June 7, 2021Date of Patent: April 16, 2024Assignee: QUALCOMM IncorporatedInventors: Peter Pui Lok Ang, Peter Gaal, Alexei Yurievitch Gorokhov, Tingfang Ji, Tao Luo, Heechoon Lee, Joseph Binamira Soriaga
