Abstract: The present disclosure describes method and system for notifying resource capability of user equipment. In accordance with the embodiments, the method includes determining an event related to one or more multimedia multicast-broadcast service (MBMS) service of interest to the UE in receive only mode (ROM) session when a system information related to MBMS is not broadcasted by a serving cell after transmission of an interest indication for MBMS service to the serving cell wherein the event indicates one of: (a) the UE is not interested in the one or more MBMS service through the ROM session; and (b) the UE is not in reception of the one or more MBMS service through the ROM session; and transmitting a ROM service interest indication for the one or more MBMS service through the ROM session corresponding to the determined event to the serving cell.

Abstract: The present disclosure discloses systems and methods for providing continuous Multimedia Broadcast Multicast Service (MBMS) and unicast services during mobility. On detecting mobility from a first cell to a second cell, the User Equipment (UE) receives system information and a preamble transmission signal. A System Information (SI) time window is determined from the system information and a Random-Access Response (RAR) window is determined using the preamble transmission signal. The UE performs either an SI-Radio Network Temporary Identifier (SI-RNTI) decode on System Information Block Type 2 (SIB2) during the SI time window or a Random Access (RA)-RNTI decode during the RAR window. Subsequently, the UE decodes MBMS-RNTI (M-RNTI) before and after the selected window based on an MBMS configuration received from the first cell. Thereafter, the UE receives a Multimedia Broadcast Single Frequency Network (MBSFN) configuration for the second cell, which is enables uninterrupted MBMS and unicast services.

Abstract: The various embodiments of the present invention disclose a system and method for Multimedia Broadcast Multicast Service (MBMS) counting operation is described herein. A method for multimedia broadcast multicast service (MBMS) counting operation is disclosed. In an embodiment of the present application, the method comprises of receiving, by an user equipment (UE), an MBMS counting request from a wireless communication network; sending, by the UE, an MBMS counting response on a dedicated path to the network, if the UE is in connected mode; and triggering, by the UE, a random access channel (RACH) procedure for sending the MBMS counting response, if the UE is in idle mode.

Abstract: A method of providing seamless reception of multimedia broadcast multicast services (MBMS) in a user equipment (UE) having multiple radio frequency (RF) terminals is provided. The method includes receiving MBMS from a primary cell (P-Cell) through a first RF terminal in the UE, receiving a command through the first RF terminal while receiving the MBMS configuring the MBMS on a second RF terminal and receiving the MBMS from a non-primary cell wherein the non-primary cell includes at least one of a secondary cell and a non-serving cell.

Abstract: A method of Physical Multicast Channel (PMCH) decoding for Multicast Broadcast Single Frequency Network (MBSFN) by a UE includes decoding a Transport Block (TB) in a first sub-frame of a Multicast Channel Scheduling Period (MSP) by a Physical (PHY) layer in the UE; providing the decoded TB to a Media Access Control (MAC) layer; performing blind decoding on all received MBSFN sub-frames, until the PHY layer receives PMCH scheduling configuration from the MAC layer; selecting at least one Logical Channel IDentifier (LCID) and Multicast Transport Channel (MTCH) scheduling information for each LCID by decoding a Multicast Channel Scheduling Information Protocol Data Unit (MSI PDU), the MSI PDU present in the decoded TB; building a PMCH scheduling configuration by the MAC layer based on the selected at least one LCID and the MTCH scheduling information; passing the PMCH scheduling configuration to the PHY layer by the MAC layer; and applying the PMCH scheduling configuration.

Abstract: A method for performing evolved multimedia broadcast and multicast service (eMBMS) counting efficiently in wireless systems is provided. The method includes receiving by a radio link control (RLC) layer of a User Equipment (UE), a Multicast Control Channel (MCCH) packet containing an MBMS counting request from a network. The RLC layer then transfers the MCCH packet to a Radio Resource Control (RRC) layer of the UE. The RRC layer processes the MBMS counting request and generating an MBMS counting response by and transmits an indication for successful reception of the MBMS counting request to the RLC layer. The RLC layer verifies if a subsequent MCCH modification boundary indication is received in a selected MCCH modification period and discards one or more subsequent MCCH packets received in a selected MCCH modification period if the MCCH modification boundary indication is not received from a physical layer.
