Methods and systems are provided for allocating resources including VoIP (voice over Internet Protocol) and Non-VoIP resources. In some embodiments, multiplexing schemes are provided for use with OFDMA (orthogonal frequency division multiplexing access) systems, for example for use in transmitting VoIP traffic. In some embodiments, various HARQ (Hybrid Automatic request) techniques are provided for use with OFDMA systems. In various embodiments, there are provided methods and systems for dealing with issues such as Handling non-full rate vocoder frames, VoIP packet jitter handling, VoIP capacity increasing schemes, persistent and non-persistent assignment of resources in OFDMA systems.

Multiplexing schemes for OFDMA

Embodiments of the invention provide methods and systems to support QoS for unicast and groupcast casting types using sidelink radio bearers over the NR PC5 interface. Embodiments of the invention provide methods and systems to configure and activate sidelink radio bearers using AS-level signaling between the Tx UE and Rx UEs over the NR PC5 interface. Embodiments of the invention provide methods and systems to perform resource allocation and resource reservation in a platoon for sidelink transmissions.

System and method for supporting sidelink radio bearers

There is provided method for managing network resources by switching the slice used to support a user equipment (UE), in a process referred to as slice handover or slice switching. There are several reasons why a slice handover may be implemented, include movement of the UE and network load balancing. Further the UE can be switched to a new slice operated by the same service provider (intra-operator handover) or a different service provider (inter-operator handover).

System and methods for network slice reselection

There is provided a method and apparatus for data transmission using shared radio bearer in order to simplify the operation of RAN access node by reducing signalling overhead related to mobility and simplifying per UE RBs setup/release operation. Using the shared radio bearer, UE mobility operation becomes transparent to access node (e.g. edge cell) and to UE. There is also provided a method and apparatus for simplifying the operation of UE for RBs setup/release and to make the Layer 2 (L2) operation independent from mobility (e.g. independent from handover).

Shared radio bearer and management of UE radio ID and ran path

Embodiments of the disclosure provide methods and systems for sidelink resource allocation in user equipment (UE) groups. The method includes, receiving, by a UE, from a radio access network (RAN) node, a first resource configuration message including configuration information for sidelink resources indicated by a sidelink resource grant and conditions for using sidelink resources of the sidelink resource grant. The method further includes receiving, from a second UE of the UE group, a second sidelink resource configuration message, the second sidelink resource configuration message including an activation indicator to activate at least a portion of the sidelink resources indicated by the sidelink resource grant. The method further includes determining the sidelink resources to be used for sidelink transmissions by combining the first and second sidelink resource configuration messages. The method further includes using the determined sidelink resources for data transmissions.

System and method for sidelink resource allocation in user equipment groups

To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.

Communication of control information using alert flag and version number

Methods described herein are for wireless communication systems. One aspect of the invention is directed to a method for a HARQ process, in which the HARQ process includes a first transmission of an encoder packet and at least one retransmission. The method involves allocating a transmission resource for each respective transmission. The method involves transmitting control information from a base station to a mobile station for each respective transmission. The control information includes information to uniquely identify the HARQ process and an identification of one of a time resource, a frequency resource and a time and frequency resource that is allocated for the transmission. In some embodiments of the invention, specific control information is signalled from a base station to a mobile station to enable RAS-HARQ operation. In some embodiments of the invention, retransmission signaling in included as part of regular unicast signaling used for both first transmission and retransmissions. In some embodiments of the invention, a 3-state acknowledgement channel and associated error recovery operation enables the base station and mobile station to recover from control signaling error and reduce packet loss.

Methods and systems for HARQ protocols

Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

Methods and systems for resource allocation

A method and system are provided having an uplink control structure and a pilot signal having minimal signal overhead for providing channel estimation and data demodulation in a wireless communication network. The uplink control structures enable mobile terminals to communicate with corresponding base stations to perform various functions including obtaining initial system access, submitting a bandwidth request, triggering a continuation of negotiated service, or providing a proposed allocation re-configuration header. A dedicated random access channel is provided to communicatively couple the base station and the mobile terminal so that the mobile terminal can select a random access signaling identification. A resource request is received at the base station to uplink resource information from the mobile terminal and an initial access information request is received from the mobile terminal to configure the base station connection. Pilot signals with varying density configurations are provided to include low density symbol patterns for multiple contiguous resource blocks and high density symbol patterns for single resource blocks.

Uplink control in a wireless communication network

A method and system for responding to demand-based charging in a communication network, such as a 5G wireless communication network. Service providers and/or infrastructure providers adjust network usage pricing dynamically based on demand. Customers such as Virtual Network operators respond to pricing adjustments by adjusting their network usage, service requirements, and/or by re-negotiating the pricing structure. Network usage can be adjusted by controlling network traffic generated in response to activity of end-user devices of the Virtual Network.

Method and apparatus for dynamically controlling customer traffic in a network under demand-based charging

Systems and methods for OFDM channelization are provided that allow for the coexistence of sub-band channels and diversity channels. Methods of defining diversity sub-channels and sub-band sub-channels are provided and systematic channel definition and labeling schemes are provided.

Systems and methods for OFDM channelization

The present invention provides a system and method for ultra reliable low latency communication (URLLC) which can be achieved by redundant transmission with two or more links at one or more RAN nodes. In order to achieve URLLC communication, methods supporting the PDCP packet duplication and/or higher layer packet duplication are applied to various RAN architectures such as CA architecture, DC based architecture with one connection to the core network (CN), DC based architecture with two or more connections to the CN, CA and DC combined architecture, and CU/DU split architecture.
