摘要： Methods, systems, and devices for wireless communications are described. The method may include receiving from a master cell group of a dual connectivity environment a first message indicating that a secondary cell group of the dual connectivity environment is suspended, maintaining a lower layer configuration for the secondary cell group and modifying a measurement report configuration for the secondary cell group based on the first message and while the secondary cell group is suspended, receiving from the master cell group a second message indicating that the secondary cell group is no longer suspended, and reconnecting to the secondary cell group using the lower layer configuration for the secondary cell group based on the second message.

摘要： Methods, systems, and devices for wireless communication are described. A user equipment (UE) may autonomously initiate a handover procedure and select a target base station for the handover procedure. The UE may measure a signal from the source base station or the target base station, or both, and the UE may determine whether specific criteria at both base stations are within a pre-configured range. If the criteria at both base stations are within the pre-configured range, the UE may identify the target base station as a potential candidate for a handover. Accordingly, when the UE determines that radio conditions with the source base station are deteriorating (or fall below a threshold), the UE may initiate a handover to the target base station autonomously and without specific direction from the source base station.

摘要： Apparatus and methods for facilitating a handover of a wireless communication device on a first wireless communication network to a second wireless communication network, wherein the first and second wireless communication networks include communications protocols that are incompatible, are disclosed. The facilitation can include establishing communications between the wireless communication device and an interworking component of the second wireless communication network using a transparent tunnel through the first wireless communication network so that a message containing session information for the second wireless communication network can be exchanged. The facilitation further includes creating a profile on the second wireless communication network for a communication session between the wireless communication device and the second wireless communication network.

摘要： A wireless communications power saving method and apparatus is provided. The method includes establishing a circular buffer configured to maintain a number of most recently encountered frame delay times and waiting a frame delay time after receiving a further frame before the station enters a power save state. Frame delay time is a period equal to a largest most recently encountered frame delay period in the circular buffer. The method further determines, at a station, a dormancy time based on a number of data frames received since the station transitioned from an inactive mode to an active mode, a packet transmission rate, and a data frame time interval representing time between data frames received at the station, and causes the station to switch to a further inactive mode if a next packet is not received within the dormancy time after receipt of a previous packet.

摘要： Methods and apparatus for an ATM network for implementing a fair servicing of all connections during a back-logged condition through the use of a weighted fair queuing technique. The system is particularly suited for systems where the packets/cells are of a fixed size. Although some important approximations are made in the proposed implementation, all of the properties of an ideal weighted fair queuing algorithm are preserved. The sorting methods and apparatus are advantageous in that it is possible to maintain appropriate servicing of connections without sorting all of the individual connections. This may be accomplished by pre-sorting each of the individual virtual circuit connections into a finite number of predetermined bins according to a weight associated with the connection. Thereafter, only the bins need be sorted without having to sort each of the individual connections. Further aspects of the invention include storing the bins in a matrix with an offset value dependent upon the current potential of the bin. In this manner, the overall sorting required to determine the next connection to service is substantially reduced. Accordingly, the invention is suitable for implementations having transmission speeds of multiple gigabits-per-second.

摘要： Some implementations provide a method for prioritizing reverse link packets so that particular reverse link packets are transmitted with a reduced latency in order to improve spectral efficiency of the forward link. The method also optionally includes weighting packets according to their determined lengths, and transmitting packets based on the determined weights. In one implementation, the method includes sorting packets at least according to one of size, type and nature of the data in the packets. Accordingly, sorting of the packets includes at least one of determining the size and the type of each packet. In one implementation, sorting the packets includes deep-packet inspection to determine a respective priority value for each packet.

摘要： Aspects described herein relate to configuring and selecting preamble and payload occasions for performing two-step random access procedures. Configurations on preamble occasions, payload occasions, association pattern between the occasions and synchronization signal block (SSB) beams, and the rules for selecting preamble and payload occasions for random access message transmission can be determined by the network and signaled to user equipment (UE). Based on the configurations and rules, UE can measure the link level quality and select possible preamble and payload occasions for one or more SSB beams achieving a threshold signal quality. Sets of one or more preamble occasions and one or more payload occasions can be further determined based on whether the preamble and payload occasion(s) can achieve a threshold transmission latency. The one or more preamble occasions and one or more payload occasions can be used to transmit random access messages in the two-step random access procedure.
