A parameter related to the predetermined window is independently configured with respect to at least one of a resource pool, a service type, a priority, a quality of service (QoS) parameter, a block error rate (BLER), a speed, a CSI payload size, a subchannel size or a frequency resource region size. | 2022-03-10 |
20220077994 | DMRS for 5G Things Communication System - Systems and methods of providing DMRS for a UE are generally described. The DMRS locations in a resource unit of a Physical Resource Allocation of a shared channel are randomly determined, and the DMRS sequences randomly generated before transmission from a master UE to a wearable UE. The DMRS locations are disposed on different subcarriers and symbols in the resource unit and are repeated every k subframes or m resource units within the same subframe. In situations in which the collision/contention probability is relatively small, DMRS in control channels may be used rather than in the shared data channel. | 2022-03-10 |
20220077995 | INFORMATION PROCESSING METHOD, DEVICE, EQUIPMENT, AND COMPUTER READABLE STORAGE MEDIUM - The embodiments of the present disclosure discloses an information processing method, a device, an equipment, and a computer readable storage medium. The information processing method of the present disclosure includes: sending first information to a terminal, wherein the first information is configured to indicate information of at least one time unit for scheduled data transmission; at least one piece of downlink control information (DCI) is sent in one time unit. | 2022-03-10 |
