Abstract: A wireless communications system includes a shared TDM data channel for communications in different time slots with respective mobile stations (MSs), as well as dedicated channels. A first medium access control (MAC) multiplexing sublayer, provided in a base station controller, maps information of logical channels for communications services to the communications channels. A second MAC multiplexing sublayer maps information, mapped to the shared data channel in the first MAC multiplexing sublayer, to respective data units for communication in respective TDM time slots of the shared channel. The second MAC multiplexing sublayer handles scheduling, adaptive modulation and coding, and automatic retransmission of information on the shared data channel, as well as shared control channels for the shared data channel and channel quality feedback and data acknowledgement channels from the MSs.

Abstract: A wireless data network architecture supports both centralized mode operation and distributed mode operation. In the centralized mode, all of the Open Systems Interconnection (OSI) reference model data link layer, also known as layer 2, protocol functions are implemented within the radio access network control entity, such as at a base station controller (BSC) or similar network controller, before the data packets are delivered to one or more base station transceiver subsystems (BTSs). In the distributed mode, some of the layer 2 protocol functions are implemented at the BSC or similar network controller, and some of the layer 2 protocol functions are implemented at the BTSs. The data transmission is dynamically switched from one of the modes to the other as a function of various implementation-specific triggers.

Abstract: In code division multiple access communication systems, there are three levels for updating locations of dormant mobile stations (MSs) and setting up fast call. In sector and are levels, the dormant MS send a layer 2 message containing a message type and MS identifier to a base transceiver station (BTS). Since the message is associated with the sector where the MS is located, the network is aware of the MS's location from the updated location. The dormant MS sends to the BTS a reconnect message containing a message type and an MS identifier. The MS's dormant to active state transition is initiated by the MS. In the communication network, sub-packet zone ID is broadcasted in the overhead message. The MS reports its location change on R-CSCH and the network with the BSC level control can page the MS within the zone where the MS sends the report.

Abstract: A method and system applicable within a mobile transmission system for adaptively allocating a downlink data rate to an access terminal to compensate for channel fading. In accordance with the method of the present invention a downlink data rate selected in accordance with a determined signal-to-noise level, wherein the downlink data rate is associated with a specified signal-to-noise threshold to achieve a specified packet error rate. Next, a packet is transmitted to an access terminal at the selected downlink data rate. In response to successfully decoding the packet at the access terminal, the signal-to-noise threshold specified for the selected downlink data rate is decreased such that subsequent data rate selections are adaptively maximized. Responsive to a packet decoding error, the signal-to-noise threshold is abruptly increased to maintain the specified packet error rate.

Abstract: A method for improving the transmission efficiency of a short data burst (SDB) in a CDMA telecommunications network by generating an SDB comprising a service reference identifier, a service option omit field indicating whether a service option identifier is to be included or omitted from the SDB, and a data block. The SDB may thus be generated without a service option identifier and, as such, be more efficiently transmitted between a base station and a mobile station, thereby resulting in a typical gain over the prior art of up to 2% of data capacity.

Abstract: A high data rate active set of base stations services high data rate forward link transmissions for a mobile station. Membership of the high data rate active set of base stations is determined via interaction with legacy standard operations that define a legacy standard active set of base stations for the mobile station. The high data rate forward link active set of base stations may be a subset of the legacy standard active set of base stations. The high data rate forward link active set of base stations may correspond directly to a reduced active set of base stations according to the legacy standard operations, e.g., reduced active set. According to another operation, access to newly added base stations to the high data rate forward link active set of base stations is precluded until the newly added base station is available to support forward link transmissions.

Abstract: A data-centric network and non-Real-Time (RT) RAN Intelligence Controller (RIC) architecture are described. The data-centric network architecture provides data plane functions (DPFs) that serve as a shared database for control functions, user functions and management functions for data plane resources in a network. The DPFs interact with control plane functions, user plane functions, management plane functions, compute plane functions, network exposure functions, and application functions of the NR network via a service interface. The non-RT RIC provides functions via rApps, manages the rApps, performs conflict mitigation and security functions, monitors machine learning (ML) performance, provides a ML model catalog that contains ML model information, provides interface terminations and stores ML data and Near-RT RIC related information in a database. An ML training host trains and evaluates ML models in the catalog, obtains training and testing data from the database, and retrains and updates the ML models.
