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.

The first apparatus further includes computer-executable instructions stored in the memory which, when executed by the processor, causes the first apparatus to: discover a second apparatus that the first apparatus can communicate with; obtain device information related to the second apparatus; and configure a radio protocol of the first apparatus for direct sidelink communication with the second apparatus.

Abstract: A communication method implemented on a 3rd Generation Partnership Project (3GPP) communication network includes providing an attachment between a group member of a communication group and a group application server, detecting a detachment between the group member and the group application server, and reestablishing the attachment by the 3GPP communication network. A Mobility Management Entity (MME) may provide the attachment. A Group Communication Service Enabler Application Server (GCSE AS) or a Multipoint Service (MuSe) functionality may detect the detachment. The attachment may be reestablished according to the MuSe functionality. A group communication bearer may have a first priority level for allocating resources to the group communication bearer, and a second priority level for allocating resources to the non-group communication bearer. The second priority level may be different from the first priority level.

Abstract: Circuit switched fallback (CSFB) requests may be managed. A mobile management entity (MME) can detect one or more pending CSFB requests. In response to detecting the pending CSFB request(s), the MME can generate a message that indicates the one or more pending CSFB requests, and can communicate the message to one of a mobile switching center (MSC) and a virtual location register (VLR).

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: 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: Method and apparatus are disclosed for calculating a target connection frame number (CFN) for a data frame in wireless communications. An update to an offset between the CFN and a radio access network frame number is computed. A target CFN variable is incremented in response to a received timer signal. The value of an update variable is checked to determine whether a new value of the offset has been received since a previous update to the offset. A new target CFN is calculated using a current target CFN and the new value of the offset on a condition that the new value of the offset has been received. The current target CFN is set equal to the new target CFN.

Abstract: A method for transmitting a data frame in a wireless communication system begins by creating a time of arrival (TOA) window, including a window start (WS) and a window end (WE). The TOA of the data frame at the air interface for transmission is determined, and further action is taken depending upon when the data frame arrives relative to the TOA window. The data frame is buffered if the TOA is before the WS. The data frame is transmitted if the TOA is within the TOA window. The data frame is discarded if the TOA is after the WE.

Abstract: In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.

Abstract: A method and apparatus is provided for reducing block error rate (BLER) estimate reporting to conserve system resources, while eliminating reports of BLER estimates unlikely to require an adjustment to target signal to interference ratio (SIR). A plurality of data blocks is received over a transmission time interval and the count of data blocks is stored in memory. The data blocks are error checked by an error check unit and the number of erroneous data blocks is stored in memory. A processor performs a BLER estimate calculation based on the data block count and erroneous data block count. A BLER estimate report is produced and sent for target SIR adjustment if triggered by threshold comparisons performed by the processor, including the data block count value compared to a predetermined threshold, and the BLER estimate value compared to a predetermined multiple of the target BLER value.
