Abstract: Examples pertaining to improvement on user equipment (UE) uplink latency in wireless communications are described. When an apparatus is in a special mode, a processor of the apparatus transmits to a network a request for permission to perform an uplink (UL) transmission for a plurality of times. The processor then receives from the network a grant. In response to receiving the grant, the processor performs the UL transmission to the network. In transmitting the request for the plurality of times, the processor transmits the request for the plurality of times at a frequency higher than a frequency at which the request to perform UL transmissions is transmitted to the network when the apparatus is in a normal operational mode.

Abstract: Solutions pertaining to allocating antennas of a user equipment (UE) between connections using different RATs are proposed. A UE has a first connection to a first network and a second connection to a second network, each connection employing a respective radio access technology (RAT). During operation, the UE may identify a precondition of reconfiguring the connections. For example, the UE may intend to change a multi-input-multi-output (MIMO) setting of the first connection in order to release some antennas that can be allocated to the second connection to relieve a communication bottleneck thereof. Prior to reconfiguring the connections, the UE may communicate its intent to the first network. The UE may not reconfigure the connections until a confirmation is received from the first network.

Abstract: A method for dynamically de-activating a secondary cell group (SCG) of dual connectivity includes: checking if at least one radio frequency (RF) band used by the SCG meets a pre-defined criterion, and in response to the at least one RF band meeting the pre-defined criterion, de-activating the SCG. For example, the at least one RF band is a 5G New Radio (NR) band.
