  • a UE is registered in a tracking area or RNA and, therefore, the network sends the paging message in all the possible cells within the tracking area.
  • the UE monitors Paging Occasions (POs) where the paging Downlink Control Indicator (DCI) can be sent once per cycle using Discontinuous Reception (DRX).
  • P-RNTI Paging- Radio Network Temporary Identifier
  • These paging DRX cycles are configured by the network:
  • a default cycle is broadcast in system information (e.g., SIB1).
  • SIB1 system information

  • MBMS Multimedia Broadcast Multicast Services
  • MBSFN Multimedia Broadcast multicast service Single Frequency Network
  • MBMS reception is supported in RRC IDLE mode.
  • Scheduling is not based on the Physical Downlink Control Channel (PDCCH) but on a combination of SIB 13 and Multicast Control CHannel (MCCH).
  • SIB13 defines which subframes are allocated for MBMS and the MBSFN areas, and for each, how to obtain the MCCH.
  • All Multicast Channels (MCHs) within one MBSFN area use a common subframe allocation (CSA) pattern. Among the subframes defined by the CSA, consecutive subframes are allocated to the same MCH.
  • the MCCH defines the CSA of the MBSFN area. A change notification for the MCCH is transmitted on the PDCCH.
  • This reception mode is an addition to the LTE MBMS idle mode reception.
  • the UEs can be in three different scenarios:
  • Scenario 1 The UE receives both unicast and broadcast service from same Public Land Mobile Network (PLMN).
  • PLMN Public Land Mobile Network
  • the UE acts in RoM: the UE receives broadcast MBMS service without PLMN subscription over Evolved Universal Terrestrial Radio Access Network (E-UTRAN) without the need to access and register with the PLMN offering the MBMS service.
  • a UE configured to operate in RoM camps on a network cell in an enhanced MBMS (eMBMS) Broadcast carrier, shall attempt to receive MBMS service based only on a standardised Temporary Mobile Group Identifier (TMGI) value range for RoM.
  • TMGI Temporary Mobile Group Identifier
  • the UE shall not attempt to receive MBMS service for TMGIs outside the standardized TMGI range.
  • the UE shall refrain from any Mobility Management or other signalling with the network offering MBMS.
  • the UE uses the acquired system information to receive MBMS broadcast.
  • Use of RoM does not require Universal Subscriber Identity Module (USIM) for the UE.
  • USIM Universal Subscriber Identity Module
  • the UE acts in RoM with independent unicast: The UE receives unicast service from one serving PLMN (e.g. the PLMN for which it has unicast subscription) and receive MBMS service through a different PLMN.
  • a UE may be configured as RoM with independent unicast using Enhanced Packet Service (EPS) bearer contexts.
  • EPS Enhanced Packet Service
  • This configuration option allows a UE to operate as RoM for MBMS broadcast service, and independently follows regular NAS/RRC procedures for unicast service with a PLMN. This mode of operation requires USIM and PLMN subscription to receive unicast service. No additional subscription or credentials are required to receive MBMS broadcast service.
  • FIGURE 1 illustrates Scenarios 2 and 3, as described above,
  • Any device that is equipped with a MBMS broadcast receiver and is configured to operate in RoM is able to receive the broadcast content, with the following characteristics:
  • the UE can only access broadcast services without subscription.
  • the UE is preconfigured with all the necessary information for the UE to acquire the system information and receive MBMS service.
  • This information includes:
  • TMGI is composed by an MBMS Service ID and a PLMN ID (Mobile Country Code/ Mobile Network Code (MCC/MNC)).
  • MCC/MNC Mobile Country Code/ Mobile Network Code
  • the TMGI(s) for each MBMS service need to be configured in the UE.
  • the UE may be configured to receive TMGI(s) via Service Announcement
  • each UE is individually paged without the possibility to select a group of UEs by using the same transmitted signal. This is due to the nature of the paging message which is a function of the individual UE_ID, i.e., the message is specific for that particular UE. In some cases, e.g., for Vehi cl e-to- Any thing (V2X) and National Security and Public Safety (NSPS) use cases, it is beneficial to include a paging mechanism that is able to address specific groups of UEs in a multicast manner.
  • V2X Vehi cl e-to- Any thing
  • NSPS National Security and Public Safety
  • a UE or group of UEs is in RRC IDLE or RRC INACTIVE mode, they need to transition to RRC CONNECTED mode before being able to receive any transmission other than paging or system information, which may lead to a higher latency in the communications and a potential cumbersome signaling if it is a highly dense scenario.

  • the paging-like messages may include any kind of messages intended for a specific group and may not have any specific properties other than that the paging-like messages indicate the BO.
  • a paging message is used to “wake-up” the UE, for example, to transition from idle/inactive to connected mode
  • these paging-like messages have a similar structure to paging messages but are not intended to “wake-up” the UEs. Rather, the paging-like messages are intended to indicate the BO to a specific group of inactive/idle UE(s).
  • the BO is sent in a paging-like message (or something similar) or in system information because the UE does not listen to anything else in the IDLE/INACTIVE mode.
  • the wireless devices normally have no uplink channel activated/enabled when in idle/inactive mode, there is no possibility to signal whether transmitted information (such as a signal or message transmitted by a network node) was successfully or unsuccessfully received, e.g., ACK/NACK, using the HARQ feedback. Nevertheless, the network node may decide to send retransmissions in a (pre)determined way. The reason for this is to increase the time diversity, i.e., the same amount of physical resource blocks (PRBs) would be transmitted as without HARQ but distributed in time over several occasions. In some reception conditions, this may result in a very significant improvement in reception performance, although at the expense of increased latency. It will be appreciated that retransmission may for example be performed for all data transport blocks that are transmitted in the BOs.

  • a motivation for doing so can be that in the case where the uplink from the UE to the gNB is anyways so bad that ACK/NACK message do not get through, it may not make sense for the UE to stay in RRC -connected, so it may transition to IIRM.
  • a triggering for UEs to move into IIRM is signaled by the network in unicast manner when the UE is in RRC CONNECTED mode.
  • This transition into IIRM is signaled using RRC messages or other network messages. Since the gNB has knowledge of the UEs in the cell, i.e., UEs which are under its coverage, it is possible to signal only a subset of the UEs so they transition to the IIRM mode.
  • the network may decide that a subset of UEs do not move into IIRM, i.e., they do not receive information in RRC IDLE/INACTIVE mode, by signaling these particular UEs.
  • a UE may potentially listen to several different DRX patterns signalled in SIB, i.e., a UE can belong to different groups at the same time, in parallel to the legacy cell-specific paging.
  • the UEs may be configured by the network to have two (or more) different DRX scheduling, i.e., one for the normal PO and one or more for the BO.
  • the reception in the BO does not require an additional DRX pattern, as the UE is just waking up for the BO which is fully specified by embodiments described above.
  • the new IIRM DRX scheduling can be signaled using RRC messages.
  • the scheduling can be configured to support several retransmissions of the same packet.
  • the priorities are defined based on service requirements, e.g., NSPS for critical services has the highest priority, or based on geographical location. This mechanism is required since the same UE could potentially belong to several groups at the same time.
  • the priority of the DRX scheduling may be signaled in the RRC messages.
  • the BO can be scrambled using a new IIRM-RNTI so only UEs in IIRM can decode it. If a UE goes into IDLE/INACTIVE mode, it automatically receives/selects the IIRM-RNTI so it can by default listen to IIRM BC/MC. The IIRM-RNTI can be sent once the UE joins the network for the first time so there is no need to transmit this information once the UE goes into IDLE/INACTIVE mode.
