Abstract:
A method and apparatus for transmitting uplink control information (UCI) for Long Term Evolution-Advanced (LTE-A) using carrier aggregation is disclosed. Methods for UCI transmission in the uplink control channel, uplink shared channel or uplink data channel are disclosed. The methods include transmitting channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), hybrid automatic repeat request (HARQ) acknowledgement/non-acknowledgement (ACK/NACK), channel status reports (CQI/PMI/RI), source routing (SR) and sounding reference signals (SRS). In addition, methods for providing flexible configuration in signaling UCI, efficient resource utilization, and support for high volume UCI overhead in LTE-A are disclosed.
Abstract:
Multiple mobility sets are maintained for nodes of radio networks. The sets comprise information such as: transmit and receive point identities; cell identities; beam identities; frequency channels; channel bandwidth; and black lists. The sets may be defined at different levels, such as network and physical (PHY) level. A network mobility set, e.g., a new-radio (NR) mobility set may, be determined by the gNB, the cell, the UE, or another device. Multiple radio access network nodes and UEs may exchange mobility set information to achieve a distributed mobility solution. A UE may monitor its orientation relative to a TRP, e.g., via use of an onboard MEMS gyroscope, and alter its beamforming parameters in response to changes in orientation and/or changes in TRP connection strength. Cell selection and reselection for beam based networks may use Single Frequency Network (SFN) broadcast of initial access signals without beam sweeping.
Abstract:
Embodiments contemplate methods and systems for determining and communicating channel state information (CSI) for one or more transmission points (or CSI reference signal resources). Embodiments further contemplate determining transmission states may include applying at least one transmission state parameter to channel state information (CSI). Embodiments also contemplate reporting CSI based on the transmission state and/or at least one transmission state parameter applied thereto.
Abstract:
A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.
Abstract:
Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to perform a multi-radio access technology (RAT) access (MRA) operation. The apparatus may include a WTRU non-access stratum (NAS) entity to communicate with a first and second NAS entity of a first and second core network (CN). Alternatively, the first WTRU NAS entity communicates with a first NAS entity of a first CN, and a second WTRU NAS entity communicates with a second NAS entity of a second CN. The apparatus may include a radio resource control (RRC) entity which controls a first RAT connected to the first CN and a second RAT connected to the second CN. Alternatively, the apparatus includes an RRC entity which controls a first connection using a first RAT connected to the first CN and a second connection using a second RAT connected to a second CN.
Abstract:
A method and apparatus are provided that allow a wireless transmit/receive unit (WTRU) to search and add one or more closed subscriber group (CSG) identities (IDs) in the WTRU white list while in connected mode. Such method and apparatus include but are not limited to WTRU autonomous search or a manual search, WTRU initiated procedures, or network initiated procedures. Additionally, methods that allow the network and/or the non-access stratum (NAS) to add CSG IDs are also described.
Abstract:
A method and apparatus are described for controlling the application of Selected Internet Protocol (IP) traffic offload (SIPTO) or Local IP Access (LIPA) services for a wireless transmit/receive unit (WTRU). The SIPTO and LIPA services may be performed over packet data network (PDN) connections. A user of the WTRU may be prompted to accept or reject the usage of the SIPTO or LIPA services. The user of the WTRU may request switching from SIPTO or LIPA services to non-SIPTO or non-LIPA services.
Abstract:
A method and apparatus for controlling or determining transmit power of transmissions on more than one component carrier (CC) is disclosed. A WTRU may set a transmit power for each of a plurality of channels mapped to multiple CCs. The channels may include at least one physical uplink shared channel (PUSCH) and may also include at least one physical uplink control channel (PUCCH).
