  • Figure 1 shows a decision tree for receiving a paging signal.
  • a UE in idle mode wakes up at defined Paging Occasions (PO) in a Paging Frame (PF) and monitors the PDCCH to check for a Paging Indication (PI) . If an indication for the UE is received a related Paging Message (PM) carried on PDSCH is decoded to ascertain if it is for the particular UE. PIs are directed to all UEs configured in a certain PO and therefore the indicated PM is not applicable for all UEs which decode the PM based on receipt of the PI.
  • the PF is a radio frame that may contain one or more POs.
  • the PO and PF for each UE are derived from the UE-ID and the current network configuration (DRX cycle and parameter nB) , thus enabling UEs to be distributed across POs.
  • PDCCH scrambled with P-RNTI in Common Search Space (C-SS) is used for scheduling the PM, and the same PM is sent by all eNBs in a given tracking area, or in multiple tracking areas for later releases of LTE, where the UE is expected.
  • C-SS Common Search Space
  • the PI &PM should be repeated on each beam as the precise location of the UE is not known. This leads to an increase in UE power consumption (UE needs to wake up for the PO in each beam, which will be at different times) , and an increase in paging overhead due to the repetition.

  • UEs can be grouped and an indication of which group is being paged included in the UE.
  • the use of a group indication can provide a very large reduction in PM length as the group indication can be much shorter than the UE-ID used to identify a particular UE.
  • the paging group indication may be in the form of a bitmap, with each bit of the indicator corresponding to a group.
  • One method to associate UEs to paging groups is through some deterministic computation utilizing some or all of the following parameters: UE ID, cell ID and system information.
  • a way to associate UEs to groups is using the UE ID (IMSI or S-TMSI) modulo number of groups.
  • the group indication may be used in combination with an indication of individual UEs. For example, if a group only contains a single UE (or small number) to be paged it may be more efficient to identify that UE explicitly, rather than the group.
  • the network can thus balance paging overhead against the impact of false paging and select the most appropriate balance.
  • Such balancing may take into account group sizes, cell sizes, number of beams, user density, and over network dynamics.
  • the number of groups in a cell can be changed dynamically, this is relatively complex as group/UE associates must be updated on a dynamic basis for all UEs affected. For this reason, it may be preferable to keep the number of groups in a cell semi-static.
  • the PFI in the DCI or PM itself may indicate that the PM contains a mix of a group indication and individual UEs.
  • a fixed format may be utilised for the PM with the group indication in a set location and the remainder of the PM comprising UE-IDs, with the total length being known from the DCI. This avoids the gNB having to indicate the PM format.
  • This kind of fixed location assignment to the paging group indication within the paging message lets all the user understand the content of the paging message without any additional signalling. Thus, no PFI style flag is required in this case.
  • the UEs may be divided into 50 groups, giving 20 UEs per group. As an example, 10 groups each carry 4 of the UEs to be paged, and 10 groups each carry a single UE to be paged, giving 20 active groups for this PO.
  • the network decides to page the ten groups with multiple UEs on a group basis (50 bits total for the group indication) , and the 10 other UEs individually.
  • the number of groups may be increased to 200, each having 5 users.
  • 12 groups carry 3 UEs, and 14 have a single UE each, giving 26 active groups.
  • the careful selection of the number of groups and group sizes can thus have a very significant effect on the total paging load and the false paging alerts.
  • the PM may also comprise UE-IDs in indicated groups that are not paged.
  • the gNB can indicate a group being paged if the majority of the users in this group are to be paged.
  • the gNB can explicitly add these UE IDs in the PM as well.
  • a UE receives a paging message and decides at 11 whether the UE is in a paged group. If the UE is not in a paged group at 12 the UE checks if it is identified explicitly and concludes whether the UE is paged 13 or not paged 14. If the UE identifiesthat it is present in a paged group, at 15 the UE checks if it is identified explicitly in the PM. If the UE is identified explicitly this is an indication that the UE is not paged as shown at 16. If the UE is not identified explicitly, the UE is paged 17.
  • This logic is that non-paged UEs in a paged group do not attempt an access request, thus preventingfalse access requests.
  • Presuming group indication is used where more than half of the group is paged then the overhead of including this negative indication is less than the overheard of explicitly identifying all of the paged UEs (rather than using groups) .
  • the PM load is thus reduced, and false access attempts are avoided.
  • This method allows thebase station (or gNB) to reduce false paging alerts at the expense of some additional paging load (IDs of unpaged UEs) .
  • a gNB it is not mandatory for a gNB to reduce the false paging alerts to zero but the proposed scheme allows the gNB to choose at each paging occasion an appropriate amount of paging load and an acceptable rate of false paging alert as a function of system parameters, number of users in the cell, number of users configured in a PO and the number of paged UEs.
  • the DCI may include an indication of active groups such that only those groups stay awake to receive and decode the PM, all other groups can immediately return to DRX after the Paging DCI.
  • the group indication could be a bitmap, or any appropriate coding that can convey the required information in the small size available in the paging DCI. Size constraints in the DCI may make large numbers of bits for a group indication in paging DCI disadvantageous.
  • a reduced number of groups may be indicated in the paging DCI, and only the UEs associated to active groups decode the PM associated to this paging DCI. Then PM can have large number of groups or finer granularity group indication for active super groups combined with the UE ID based paging.
  • This technique provides multi-layer grouping, with the first level in the Paging DCI giving power savings to inactive group members, and the second level reducing overhead and false alarms as indicated above.
  • the paging message overhead can be further reduced by compressing the UE-IDs to reduce the transmitted data.
  • the compression reduces the data required, albeit with a small risk of compressing two UE-IDs to the same value and hence introducing ambiguity. Even in such a situation both UEs will initiate an access attempt, one of which will be false and can be refused.
  • P-RNTI paging RNTI
  • a group common P-RNTI is assigned to all UEs allocated to a corresponding group.
  • Non-indicated groups of UEs thus reduce power consumption as they do not stay awake to receive and process the PM.
  • a drawback of this approach is the increased DL overhead for PI transmission if a large number of groups are being paged.
  • a network may have a pre-defined pool of RNTIs which are used as group common P-RNTIs, which pool of group common P-RNTIs can be known a-priori by all UEs.
  • UEs can be associated to groups in any appropriate manner, for example based on UE-ID, or a combination of UE-ID and other system information such as cell ID, SFN, or PO number.
  • This approach of group common P-RNTIs may be equally attractive for non-beam sweeping applications.
  • all UEs allocated to a PO listen and decode the PM, even if the PM was only for a single UE.
  • the allocation of one universal and one group-common RNTI for each UE provides potentially significant savings.
  • a further advantage of multiple group common P-RNTIs is a potential increase in paging capacity for dense cells.
  • the universal P-RNTI is more attractive where a PM is intended for all, or most, UEs in a cell; for example when the PM relates to a change in system information.
