Abstract: Briefly, in accordance with one or more embodiments, a user equipment (UE) may enter into an E-UTRAN Routing Area Paging Channel state, and is configured with an E-UTRAN Routing Area and an Anchor identifier to identify an anchor evolved Node B (eNB) for the UE. The UE selects to a new cell without performing a handover procedure, and performs a cell update procedure. The UE also may enter into a Cell Update Connected state, and is configured with an Anchor identifier. The UE selects to a new cell, performs a cell update procedure, performs a buffer request procedure, and performs a cell update procedure to download buffered data and to perform data transmission with the new cell.

Abstract: In an embodiment, an apparatus to be employed in a user equipment (UE) is described. The apparatus includes configuration circuitry operable to determine, based on one or more configuration information messages, a measurement gap for a master evolved Node B (MeNB) that is operable to provide a master cell group (MCG) that is asynchronous with a secondary cell group (SCG) of a secondary evolved Node B (SeNB), wherein subframe boundaries of the MCG are different from subframe boundaries of the SCG; and radio frequency (RF) control circuitry operable to cause RF circuitry to be tuned, at a beginning of the measurement gap based on a subframe boundary of the MCG, to start inter-frequency measurements, wherein the RF circuitry is to be used to transmit or receive data in a serving cell of the MCG and in a serving cell of the SCG. Other embodiments are also described and claimed.

Abstract: A User Equipment (UE) may receive carrier combinations supported by a Radio Access Network (RAN) node and a list of frequency bands that the RAN node may have the UE measure. The UE may determine all of the possible scenarios of how the carrier combinations may be matched to different sets of frequency bands. For each scenario, the UE may determine the number of effective frequencies based on the quantity of frequency bands in the scenario but only counting frequency bands that the UE may measure in parallel (e.g., at the same time) as a single frequency band. The UE may determine a measurement gap for each component carrier in each scenario, and communicate, to the RAN node, the number of effective frequencies and the measurement gaps for each scenario.

Abstract: Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may receive, from the UE, a first measurement report that indicates a first signal quality measurement based on new radio synchronization signals (NR-SS). The gNB may determine, based on reception of the first measurement report, a transmission direction for transmission of channel state information reference signals (CSI-RS) for a second RRM measurement at the UE based on the CSI-RS. The gNB may receive, from the UE, a second measurement report that indicates a second signal quality measurement based on the CSI-RS. The gNB may determine, based at least partly on the first and second signal quality measurements, whether to initiate a handover of the UE from a serving cell to a neighbor cell.

Abstract: Systems and methods for signaling in an increased carrier monitoring wireless communication environment are disclosed herein. A user equipment (UE) may include control circuitry to configure the UE for increased carrier monitoring; determine, based on a first signal received from a network apparatus, whether a reduced performance group carrier is configured; determine, based on a second signal received from the network apparatus, whether a scaling factor is configured; and in response to a determination that no reduced performance group carrier is configured and a determination that no scaling factor is configured, allow the UE to monitor fewer carriers than required by increased carrier monitoring. Other embodiments may be disclosed and/or claimed.

Abstract: New radio (NR), also known as fifth generation (5G) radio or fifth generation long term evolution (5G LTE)) uses a measurement gap that allows for measurement on different beams, multiple frame structure and inter-radio access technology measurement. For example, in measurement on the different beams, the UE (114) and eNB (304) beam sweep (i.e., change analog beam transmitter). The UE (114) can measure different beams from a fifth generation node B (gNB) and/or other RAN nodes. The measurement gap can be used for intrafrequency/interfrequency measurement when beam specific reference signals (BRSs) are not transmitted in the same subframe. A multiple frame structure can use the specific measurement configuration to utilize the beam resources efficiently. LTE and NR and other interRAT measurement can also use the measurement gap.

Abstract: Technology for a mobility management entity (MME) operable to provide core network assistance information is disclosed. The MME can determine the core network assistance information. The core network assistance information can include one or more of: an average connected state time for a user equipment (UE), an average idle state time for the UE, or a number of handover procedures between cells that occur for the UE in a selected time period. The MME can encode the core network assistance information for transmission from the MME to an eNodeB of the UE.

Abstract: Techniques for enhancing the inter-frequency measurement gap to reduce measurement delay between an user equipment (UE) and an evolved NodeB (eNB). These embodiments may include identifying, by a UE, a measurement gap configuration that includes a measurement gap repetition period (MGRP), that is less than 40 milliseconds, ms; and performing inter-frequency or inter-radio access technology, RAT, measurement based on the measurement gap configuration. The embodiments may also include receiving, by an eNB, a request from a UE, for a measurement gap configuration that includes a measurement gap repetition period (MGRP) less than 40 ms; and transmitting an indication of a gap pattern that includes a MGRP that is less than 40 ms. Other embodiments may be described and/or claimed.

Abstract: A network device (e.g., an evolved Node B (eNB) or user equipment (UE)) can process or generate a measurement gap pattern to enable network measurements of carriers or bands during measurement gaps on a per component carrier (CC) basis. The transmitting or receiving of the measurement objects (e.g., carriers or band) communicatively coupled on the network and the measurement gap pattern can be communicated via one or more radio resource control (RRC) signals, and re-configured according to a supporting CC data set identifying one or more criteria related to each CC such as UE capabilities, associations of the UE capabilities to measurement gap configurations, types of measurement gap period/gap offsets, different measurement gap patterns, an absence of a measurement gap, or other criteria related to CCs, respectively. In response to the supporting CC data set, measurement gap patterns can be dynamically re-configured per CC.
