Abstract: In a 5G or 6G network with high traffic density, wireless users are often forced to delay important transmissions, to avoid interference with other users. For enhanced efficiency and reduced overall latency, a base station can provide an uplink grant to the waiting user before the mandated delay has expired, thereby avoiding wasted time and wasted resources. The base station can determine which user has waited the longest time, and can provide the grant to that longest-delayed user. Message priority and length, and other factors, can also be considered in selecting which user to accelerate, depending on network rules. By allowing a delayed user to immediately transmit when conditions allow, the base station can reduce the average delay per message transmission, assist users in uploading their messages, and enhance network efficiency generally.

Abstract: A delay doppler domain transformation can be used to estimate characteristics of a channel between a base station and a user equipment or alternatively, between the user equipment and another user equipment. Thus, the velocity and the distance position of the user equipment can be calculated. For example, a signal received in the time-frequency domain, can be converted to the delay doppler domain by the base station. In response to the conversion, the base station can estimate the velocity of the user equipment. The velocity can be utilized by various applications. For example, the velocity can be utilized to alert the other user equipment to the location or an anticipated location of the user equipment.
