In some embodiments, a method of performing beam alignment by a user equipment (UE) of a wireless network, includes determining, by the UE based on a plurality of parameters associated with the UE, a first quality level of a connection of the UE in a first orientation and at a geographical location. The connection uses a first beam from at least one network entity of the wireless network. The method further includes determining, by the UE based on the first quality level, a second orientation from a plurality of orientations at the geographical location.

Abstract: Embodiments herein disclose UE based implementations to manage voice/video over new radio (VoNR)/EPSFB calls. In an embodiment, there can be a zero CQI reporting for indicating a signal deterioration during the VoNR call. In an embodiment, at least one of a Wi-Fi network or a dual SIM dual standby (DSDS) feature, a UE initiated fallback procedure and an internet bearer can be used for continuing the VoNR call. Various embodiments may reduce the call failures and manage calls on VoNR/5G which can be useful to the UE in volatile signal conditions.

Abstract: A method for handling data, dangling in a new radio (NR) leg of a split bearer, by a user equipment (UE) is disclosed. The method comprises predicting occurrence of NR uplink (UL) leg switch; sending a buffer status report (BSR) pertaining to protocol data units (PDUs) in radio link control (RLC) layer and media access control (MAC) layer in the NR leg based on predicting the occurrence of NR UL leg switch; and initiating recovery of dangling PDUs in the NR leg after the occurrence of the NR UL leg switch, wherein the recovery includes sending the dangling PDUs to a long term evolution (LTE) leg of the split bearer.

Abstract: A method for selecting cell using a fifth generation (5G) user equipment (UE) is provided. The method includes detecting an event, when the 5G UE is camped on a serving cell; detecting availability of one or more voice over new radio (VoNR) cells and one or more non-VoNR cells in vicinity of the serving cell in response to detecting the event; based on the event, performing one of (i) selecting a VoNR cell when only one VoNR cell is available, (ii) identifying and selecting a VoNR cell based on a plurality of cell parameters, when a plurality of VoNR cells are available, and (iii) identifying and selecting a non-VoNR cell from the one or more non-VoNR cells, based on the plurality of cell parameters, when one of the one or more non-VoNR cells is available.

Abstract: A method for managing sleep duration in a 5th Generation (5G) and a user equipment (UE) are provided. The method includes sending, by the UE, a plurality of data packets to a network in a connected mode discontinuous reception (cDRX) cycle and detecting, by the UE, an initiation of a retransmission timer associated with the plurality of data packets. The method includes determining, by the UE, if a retransmission of at least one data packet the plurality of data packets is required, and causing, by the UE, to sleep before an expiry of the retransmission timer, in response to determining that the retransmission of the at least one data packet of the plurality of data packets is not required.

Abstract: A method for prioritizing data packets in a wireless network. Data packets are received at a SDAP buffer. Flow queues may be created by dividing PDCP buffer into high priority flow queue and low priority flow queue to determine priority for each data packets based on QoS parameters. Based on QoS parameters performing one of transmitting the at least one data packet from the at least one high priority flow queue and delaying transmission of at least one data packet of the at least one low priority flow queue by buffering the at least one data packet, the electronic device may be configured with connectivity or transmitting data packets from high priority flow queue to first stack and data packet from the low priority flow queue to second stack, when the electronic device may be configured with multi RAT multi connectivity.

Abstract: Methods and systems for ensuring continuity of services on handover from Wi-Fi to cellular networks are disclosed. Embodiments of the disclosure allow a UE to seamlessly engage in a call during a handover, which is triggered on detecting that QoS of the call is less than a threshold within a coverage area of the Wi-Fi. The continuity of the call is ensured by triggering a handover from Wi-Fi to LTE and preventing/reducing handover from Wi-Fi to NR. The UE avails calling services using LTE and data services using NR, by enabling NSA mode. The UE is allowed to avail calling services seamlessly by initiating a handover of the calling services from Wi-Fi to LTE and avail data services seamlessly by initiating a handover of the data services from Wi-Fi to NR. The handover from Wi-Fi to LTE/NR is initiated if QoS of the calling/data services is less than a threshold in Wi-Fi coverage area.
