Description

Some exemplary embodiments may generally relate to mobile or radio telecommunications systems such as Long-Term Evolution (LTE) or fifth-generation (5G) radio access technology or new radio (NR) access technology, or other communication systems. For example, certain embodiments may relate to systems and/or methods for beam management (BM) reporting, for instance, in Layer 1/Layer 2 (L1/L2) centric mobility. Examples of mobile or wireless telecommunications systems include Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN), Long-Term Evolution (LTE) Evolved UTRAN (E-UTRAN), LTE Advanced (LTE-A), MultiFire, LTE-A Pro, and/or fifth-generation (5G) radio access technology or new radio (NR) access technology. 5G radio systems refer to next-generation (NG) radio systems and network architectures. While 5G systems are mostly built on 5G new radio (NR), 5G (or NG) networks can also be built on E-UTRAN radio. NR is estimated to offer bitrates on the order of 10-20 Gbit/s or higher, and is capable of supporting service categories such as Enhanced Mobile Broadband (eMBB), Ultra-High Reliability Low Latency Communications (URLLLC), and Massive Machine-Type Communications (mMTC). NR is expected to support the Internet of Things (IoT) by providing extremely wideband, ultra-robust, low-latency connectivity, and high-capacity networking. As IoT and machine-to-machine (M2M) communications become more widespread, the need for networks that meet the requirements of low power, low data rates, and long battery life will increase. Next-generation radio access networks (NG-RAN), representing RAN for 5G, are capable of providing both NR and LTE (and LTE Advanced) radio access. In 5G, nodes capable of providing wireless access functionality to user devices (i.e., similar to Node B (NB) in UTRAN or Evolved NB (eNB) in LTE) may be referred to as Next Generation NB (gNB) when built with NR radio, and as Next Generation eNB (NG-eNB) when built with E-UTRA radio. One embodiment relates to a device that may include at least one processor and at least one memory containing computer program code. The at least one memory and the computer program code may be configured to use at least one processor to cause the device to determine that at least one reporting setting needs to be activated, and to provide a signal to the network to activate at least one reporting setting. Another embodiment relates to a method that may include determining that at least one reporting setting needs to be activated on user equipment. The method may also include providing a signal to the network to activate at least one reporting setting. In a modified version, the method may also include receiving from the network the activation of at least one beam management reporting setting or at least one setting for a beam management reporting setting, and performing beam management reporting according to the activated at least one beam management reporting setting. In some variations, the method may also include sending beam management reports to the network according to at least one activated beam management reporting configuration. Another embodiment may relate to a device that includes means for determining that at least one reporting setting needs to be activated, and means for providing a network with instructions to activate at least one reporting setting. Another embodiment relates to a device that may include at least one processor and at least one memory containing computer program code. The at least one memory and the computer program code may be configured, using at least one processor, to cause the device to receive instructions from at least one user device to activate at least one reporting setting, to determine at least one beam management reporting setting that the at least one user device should activate, and to signal the determined at least one beam management reporting setting to the at least one user device. Another embodiment may involve a method that includes receiving instructions from at least one user device to activate at least one reporting setting. The method may also include determining at least one beam management reporting setting that at least one user device should activate, and signaling the determined at least one beam management reporting setting to at least one user device. Another embodiment may involve an apparatus that includes means for receiving instructions from at least one user device to activate at least one reporting setting, means for determining at least one beam management reporting setting that at least one user device should activate, and means for signaling the determined at least one beam management reporting setting to at least one user device.
