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: In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size.

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.

Abstract: Methods, systems, and devices for wireless communication are described. The described techniques relate to improved methods, systems, devices, or apparatuses that support a 20 MHz station (STA) parked on a secondary channel. Without the described techniques, mechanisms to support secondary channel operation may be unable to receive management frames or broadcast traffic from an access point (AP), which may cause the STA to lose synchronization with the AP, miss a channel change or other critical announcement from the AP, etc. Considerations for providing such information to STAs parked on a secondary channel are discussed. In some examples, an AP may restrict resource unit allocation to the secondary channel on which the STA is parked. In some cases, a trigger-based random access mechanism may utilize aspects of the present disclosure to limit access to certain resource units to STAs on a given secondary channel.

Abstract: Transmission of uplink messages by user devices in 5G and 6G involves substantial delays and numerous complex steps. For lower latency and simpler operation, procedures are disclosed by which a user device can transmit an uplink message in an unscheduled but monitored channel, allocated for at-will transmissions. The user device can transmit a header including, for example, the identity code of the user device, the size of a subsequent data message, and the destination address, followed by the data message. To reduce unnecessary delays, the user device can calculate when the data message is expected to be ready to transmit, and can start transmitting the header at an earlier time, calculated to be finished when the data message will be ready. The data message is then transmitted with zero delay. When low latency is required, the disclosed procedures can reduce delays substantially. Many additional aspects are disclosed.
