Patent Description:
3GPP document R1-<NUM> discusses a User Equipment (UE)-group wake-up signal for machine type communication (MTC).

3GPP document R3-<NUM> provides considerations on a UE-group wake-up signal.

Preferred embodiments of the invention are defined by the dependent claims.

While several embodiments and/or examples are disclosed throughout this description, the subject matter for which protection is sought is limited to such examples and/or embodiments that are encompassed by the scope of the appended claims.

A UE may be configured for discontinuous reception (DRX). The UE may monitor for a page from the base station in order to determine whether to wake up to receiving communication from the base station. In some instances, a wake-up signal (WUS) can be sent from a base station to a UE in order to provide notification of an upcoming paging occasion (PO). When sending and receiving multiple WUSs and POs, it can be beneficial to determine a strategy and/or conserve the amount of WUSs and POs that are sent throughout the wireless system. By doing so, the overall power consumption of the wireless system can be improved.

UEs may be configured to support a group WUS where a base station can group a plurality of UEs into one or more UE groups and transmit a group WUS to a particular group of UEs. The base station may be able to assign a UE group identification or a group WUS sequence to the UE group. Grouping the UEs allows the base station to transmit a WUS to a specific set of UEs rather than transmitting the WUS to all UEs being served by the base station. Grouping the UEs allows the base station to determine and transmit a WUS identifying which UEs within the UE group should wake-up for a paging occasion (PO). Prior to receiving the transmission, the UEs can listen for the WUS. After receiving the WUS, the identified UEs can wake-up before receiving the corresponding PO. Each WUS may have a duration, which may be limited by a maximum allowed WUS duration. Additionally, a gap period may be provided between the end of the WUS and the PO.

The base station can also determine the total number of different UE groups, wherein each UE is assigned to a particular group. Within each group, some UEs may be capable of being assigned to a UE group, while other UEs may not be capable of being assigned to a UE group. In some aspects, each legacy or ungrouped UE can receive the same WUS, e.g., a legacy WUS, and each grouped UE can receive a WUS that targets the particular group or sub-group for that UE, e.g., a group-specific WUS. The legacy WUS can identify which legacy or ungrouped UEs should wake-up for an ungrouped PO. Likewise, the group-specific WUS can identify which grouped UE should wake-up for a group-specific PO.

In an aspect of the disclosure, a method, a computer program, and an apparatus are provided for wireless communication at a UE for monitoring for a group WUS. The apparatus receives, from a base station, a resource allocation of a group wake-up signal (WUS) resource assigned to one or more UEs in a UE group. The apparatus determines a location of the group WUS resource within a set of WUS resources associated with a paging occasion based on a frequency location of an ungrouped WUS that implicitly indicates which of a plurality of WUS resource patterns is used. The apparatus monitors for a group WUS at the determined location in the resource allocation of the group WUS resource.

In the following description, some basic aspects of wireless communications systems are explained with reference to <FIG>, <FIG> and <FIG>. The invention is described with reference to <FIG>, <FIG>, <FIG>, <FIG>, <FIG>, <FIG> and <FIG>. Explanations with reference to the remaining Figs. may be found useful for understanding the present invention.

The base stations <NUM> configured for <NUM> LTE (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) may interface with the EPC <NUM> through backhaul links <NUM> (e.g., S1 interface). The base stations <NUM> configured for 5GNR (collectively referred to as Next Generation RAN (NG-RAN)) may interface with core network <NUM> through backhaul links <NUM>. The base stations <NUM> may communicate directly or indirectly (e.g., through the EPC <NUM> or core network <NUM>) with each other over backhaul links <NUM> (e.g., X2 interface).

Referring again to <FIG>, in certain aspects, the UE <NUM> may be configured to monitor for a group WUS at a determined location. For example, the UE <NUM> of <FIG> may include a monitor component <NUM> configured to monitor for a group WUS at a determined location in an allocation of resources. The UE <NUM> may receive, from a base station, the allocation of resources assigned to noe or more UEs in a UE group, the allocation of resources comprising a group WUS resource. The UE <NUM> may determine a location of the group WUS resource within a set of WUS resources associated with a paging occasion.

Referring again to <FIG>, in certain aspects, the base station <NUM>/<NUM> may be configured to transmit a group WUS resource. For example, the base station <NUM>/<NUM> of <FIG> may include a WUS component <NUM> configured to transmit, to one or more UEs in a UE group, an allocation of resources assigned to the one or more UEs in the UE group, the allocation of resources comprising a group WUS resource within a set of WUS resources associated with a paging occasion. The base station <NUM>/<NUM> may group one or more UEs in the UE group.

The subcarrier spacing may be equal to <NUM>µ * <NUM> kKz, where µ is the numerology <NUM> to <NUM>. The subcarrier spacing is <NUM> and symbol duration is approximately <NUM>.

UEs may be configured for a group WUS. A base station can group a plurality of UEs into one or more UE groups and may transmit a group WUS to a particular group of UEs. The base station may be able to assign a UE group identification or a group WUS sequence to the UE group. Grouping the UEs allows the base station to transmit a WUS to a specific set of UEs within a particular UE group, instead of transmitting the WUS to all UEs served by the base station. Grouping the UEs allows the base station to determine and transmit a WUS identifying which UEs within the UE group should wake-up for a paging occasion (PO). Prior to receiving the transmission, the UEs can listen for the WUS. After receiving the WUS, the identified UEs can wake-up before receiving the corresponding PO. Each WUS may have a duration that is limited to avoid exceeding a maximum allowed WUS duration. Additionally, a gap period may be provided between the end of the WUS and the PO.

The base station can also determine the total number of different UE groups, wherein each UE is assigned to a particular group. Within each group, there can be group-capable or grouped UEs and/or ungrouped UEs. The ungrouped UEs may be UEs that do not support a group WUS or is not assigned to a group WUS. An ungrouped WUS may be referred to as a legacy WUS. The grouped UEs may be UE that are capable of being assigned to a UE group, while the legacy or ungrouped UEs may not be capable of being assigned to a UE group. In some aspects, each ungrouped UE can receive the same WUS, e.g., an ungrouped WUS, and each grouped UE can receive a group WUS that targets the particular group or sub-group for that UE, e.g., a group-specific WUS. The ungrouped WUS can identify which ungrouped UEs should wake-up for an ungrouped PO. Likewise, the group WUS can identify which grouped UEs should wake-up for a group-specific PO.

According to a first implementation, up to two time-multiplexed WUS resources, for both the ungrouped WUS and the group WUS, may be configured. The first implementation may be applied for communication based on NB-IoT as well as other types of wireless communication. The location of a group WUS may be determined in relation to the ungrouped WUS. In instances where one group WUS resource is configured, the group WUS resource may be configured to coincide with the ungrouped WUS resource or to occur immediately before the ungrouped WUS resource. In instances where two group WUS resources are configured, the first group WUS resource may coincide with the ungrouped WUS resource and the second group WUS resource may occur immediately before the first group WUS resource.

According to a second implementation, the ungrouped WUS and group WUS may be configured simultaneously to have up to <NUM> orthogonal WUS resources including the ungrouped WUS resources. The second implementation may be employed, for example, for machine type communication (MTC) as well as other types of wireless communication. Up to <NUM> orthogonal resources including the ungrouped WUS resource may be configured in the time domain, while up to <NUM> orthogonal resources may be configured in the frequency domain. In some instances, the two orthogonal resources do not necessarily include the ungrouped WUS resource.

An ungrouped WUS and a group WUS may be configured on the same ungrouped WUS resource based on system information. If a group WUS is configured to share WUS resources with a non-group WUS, a common WUS that is common for all of the groups of UEs may be configured to be a non-group WUS or a legacy WUS. The common WUS may also be configured to be a group WUS that is common to all UE groups, and therefore may not be considered a legacy WUS. The group WUS may use the same gap configurations as the ungrouped WUS, with the exception of differences from possible TDM. The use of the same gap period in time may help to avoid additional signaling for a separate gap configuration. A UE may assume that a transmit power for a group WUS and an ungrouped WUS is the same. The base station may set a power offset for both the grouped and ungrouped WUS relative to a reference signal, e.g., WUS energy per resource element (EPRE) relative to cell-specific reference signal (RS) EPRE. Additionally, a maximum WUS duration for the group WUS may be the same as for the ungrouped WUS.

A UE may detect <NUM> sequences, the common WUS (that is common to all of the UE groups) and the group WUS associated to the group to which the UE belongs. For at least a group WUS in the same WUS resource, an ungrouped WUS with phase shifts "g" may be selected as a group WUS sequence design according to the following:
<MAT>
<MAT>.

The sequence resulting from g = <NUM> may be the common WUS, unless a common WUS is configured to be an ungrouped WUS. Different WUS resources may use different scrambling sequences by using different initialization seeds, e.g., c_init, or by using different truncated part of a long scrambling sequence with same scrambling seed as that of ungrouped WUS.

In some instances, the group WUS may be enabled independently from the ungrouped WUS. For example, the group WUS may be enabled without enabling the ungrouped WUS. Alternatively, the group WUS and the ungrouped WUS may both be enabled. Presented herein are aspects of the disclosure directed to indicating the configuration of the group WUS. As presented herein, the group WUS configuration may be determined using at least some of the parameters of the ungrouped WUS.

<FIG> illustrates examples <NUM> of patterns of WUS resources. In some instances, WUS resources that are associated with the same PO and same gap on the same narrow band may be consecutive to each other. This allows for a reduction in peak to average power ration (PAPR) as well as the combinations of the patterns. The WUS resources may include the resources used to transmit ungrouped and group WUS sequences. In instances where the ungrouped WUS is configured, the location of the WUS resource (e.g., #<NUM>) for ungrouped WUS sequence (e.g., #<NUM>) may be used to indicate the location of other WUS resources used to transmit other group WUS sequences. In some aspects, if the ungrouped WUS resource #<NUM> is located in the top <NUM>-RB (a first resource block and a second resource block) of a six resource block bandwidth, Pattern <NUM><NUM> may be used. In some aspects, if the ungrouped WUS resource #<NUM> is located in the center <NUM>-RB (a third resource block and a fourth resource block) of the six resource block bandwidth, a <NUM>-bit indication may be used to indicate the desired pattern, for example Pattern <NUM>-<NUM><NUM> or Pattern <NUM>-<NUM><NUM> may be used. In some aspects, one of the Patterns <NUM>-<NUM> or <NUM>-<NUM> may be predefined without additional signaling. In yet some aspects, if the ungrouped WUS resource #<NUM> is located in the bottom <NUM>-RB (a fifth resource block and a sixth resource block) of the six resource block bandwidth, then Pattern <NUM><NUM> may be used. The WUS resources #<NUM>, #<NUM>, and #<NUM> may be configured to transmit group WUS sequences, while the WUS resource #<NUM> may be configured to be shared by the ungrouped WUS sequence and group WUS sequences. In aspects where the ungrouped WUS is not configured, then all the WUS resources are used to transmit group WUS sequences. In some aspects, a <NUM>-bit indication may be used to indicate the WUS resource #<NUM> frequency position, such as the top, center or bottom <NUM>-PRB in the six-RB bandwidth, which also implicitly indicated the Pattern <NUM>, <NUM>-<NUM> or <NUM> based on the indicated location of WUS resource #<NUM>, respectively; while in some aspects, a <NUM>-bit indication may be used to directly indicate Patterns <NUM>, <NUM>-<NUM>, <NUM>-<NUM>, or <NUM>. Table <NUM> summarizes the location of WUS resource Pattern <NUM>, <NUM> (same as Pattern <NUM>-<NUM>) or <NUM>, where a 1st time slot for WUS (e.g., corresponding to WUS resource #<NUM> for NB-IoT, WUS resource #<NUM>, #<NUM> for MTC) may be the time duration of [w0, g0-<NUM>], starting from subframe w0 and ends in subframe g0-<NUM> with w0 as the latest subframe such that there is a total of valid DL subframe for the configured WUS max duration in the maximum duration and g0 as g0 = PO - timeoffset (same as that of ungrouped WUS); and a 2nd time slot for WUS (e.g., corresponding to WUS resource #<NUM> for NB-IoT, WUS resource #<NUM>, #<NUM> for MTC) is defined as [w0',w0-<NUM>], starting from w0' subframe and ends in subframe w0-<NUM> with w0' as the latest subframe such that there is a total of valid DL subframe for the configured WUS max duration in the maximum duration. In this regard, there may be a total of valid DL subframe for the <NUM> times of WUS max duration that ends in subframe g0-<NUM>. If ungrouped WUS is configured, the location of the WUS resources for group WUS may be dependent on the configuration of the ungrouped WUS configuration. The ungrouped WUS freqLocation {n0, n2, or n4} can be used to indicate Pattern <NUM>, <NUM> or <NUM> implicitly based on the predefined table. The number of WUS resources for group WUS can be M={<NUM>, <NUM>, <NUM> or <NUM>}, which requires 2bits. The location and number of WUS resources may be jointed signaled as WUS resource patterns. With the configured WUS resource pattern, the WUS resource index increases in frequency first and time second manner relative to the legacy WUS resource (e.g., WUS resource #<NUM> and #<NUM> FDMed in the same time slot, and WUS resource #<NUM> and #<NUM> FDMed in another time slot for MTC). In addition, 1bit is used to indicate whether WUS resource#<NUM> for ungrouped WUS is allocated to be shared by ungrouped WUS and group WUS or not. Therefore, in total 3bits may be utilized to indicate the number M and indices <MAT> for non-legacy WUS resources as: if <MAT> is used for group WUS, <MAT> with {m = <NUM>. (M - <NUM>)} and M=<NUM>, <NUM>, <NUM> or <NUM>; otherwise, <MAT> with { m = <NUM>. (M - <NUM>)} and M=<NUM>, <NUM>, or <NUM>. On the other hand, if ungrouped WUS is not configured, <MAT> can be used for group WUS. 2bits are used to indicate <MAT> with { m = <NUM>. (M - <NUM>)} and M=<NUM>, <NUM>, <NUM> or <NUM> for WUS resources of group WUS. In addition, if the <NUM>-bit freqLocation for WUS resource#<NUM> is introduced for group WUS (similar as that of ungrouped WUS), the WUS resource location can be selected among Pattern <NUM>, <NUM> and <NUM> in Table <NUM>. Alternatively, 1bit is introduced to choose Pattern <NUM> or Pattern <NUM> considering the similarity of <NUM>-resource location for Pattern <NUM> and <NUM> to limit <NUM> bits in total for WUS resource configuration for group WUS.

<FIG> illustrates additional examples <NUM> of patterns of WUS resources. A distinction between the patterns of <FIG> and those of <FIG>, is that the patterns of <FIG> include resources that are not consecutive in time and/or frequency. The patterns having non-consecutive mapping may allow for scheduling flexibility and may improve frequency diversity in instances where frequency hopping or alternating UE group among different WUS resources is enabled.

<FIG> illustrates an example <NUM> of WUS mapping in eDRX mode. A UE may be configured by a base station for a DRX mode or eDRX. When there is no data to be transmitted between the UE and base station in either direction, e.g., no uplink or downlink transmissions, the UE may enter the DRX mode or eDRX mode in which the UE may monitor a control channel discontinuously using a sleep and wake cycle. eDRX mode is similar to DRX but has longer timer values which allows the UE to remain in a sleep cycle for a longer duration than DRX, which may increase power savings. DRX and eDRX may help to conserve battery power at the UE. Without DRX/eDRX, the UE would need to monitor the control channel in every subframe to check whether there is data for the UE. Continuous monitoring of the control channel places a demand on the UE's battery power. The base station may send a WUS to a UE in advance of a PO when the base station will transmit communication to the UE. If the UE receives a WUS, the UE may wake-up by preparing to receive the communication during the PO. If the UE does not receive a WUS, the UE may return to the sleep mode.

In some aspects, a UE that supports eDRX with the ungrouped WUS may be configured with the number of POs associated with an ungrouped WUS. Based on the configuration, the UE monitors one WUS that is associated with a group of consecutive POs for power savings. If the UE is configured with a number of POs that is equal to three, the UE will monitor a WUS and will either wake up or remain in a sleep mode for the three POs associated with the WUS based on whether the UE receives the WUS. In some aspects, for UEs that support eDRX and group WUS, when an ungrouped WUS is configured, the number of POs may be applied to eDRX UEs to enable the ungrouped and group WUS associated with the same group of consecutive POs on the same narrowband or carriers. In some aspects, when ungrouped WUS is not configured, for eDRX UEs with group WUS, the number of POs may be configured to enable the group WUS associated with the same group of consecutive POs on the same narrowband or carriers.

In some aspects, a UE may be configured to alternate between UE groups. Grouped UEs may be configured to alternate WUS UE groups among M configured WUS resources, where M = <NUM>, <NUM>, <NUM>. In instances where there are more than one WUS resource allocated for group WUS, e.g., M><NUM>, the UE group(s) may be enabled to monitor the resource with predefined WUS resource index order in different POs. Alternating UE groups may be implicitly enabled when M><NUM> or explicitly enabled by 1bit in SIB per cell-specific, e.g., for MTC group WUS or carrier-specific, e.g., for NB-IoT group WUS. For MTC, up to <NUM> WUS resources can be allocated for group WUS, i.e., M<=<NUM>; and for NB-IoT, up to <NUM> WUS resources can be allocated for group WUS, i.e., M<=<NUM>, which means alternating the UE groups only if M=<NUM> for NB-IoT WUS.

There are different ways to alternate the UE groups. A first method may be to alternate all UE groups per WUS resource together (change WUS resource ID only), as illustrated as
<MAT>
where.

with Tcell and Tmin to be indicated in SIB respectively or Tcell and Tmin to be predefined as the maximum and minimum value of the possible UE-specific DRX cycles respectively.

A second method may be to alternate a minimum number of UE groups based on the UE group ID (change WUS resource ID and phase ID for group WUS), as illustrated as
<MAT>
where.

The first method includes a change of the resource ID, while keeping the same phase of the WUS sequence, which is based on the group ID in a WUS resource, and does not change the UE groups allocated in one WUS resource. Especially when considering service-based UE grouping, the UE groups with different services have different paging probability. It is more reasonable to use different WUS resources to separate the UE groups with different services to avoid the impact of services with large paging probability on the other services. The second method may include a change of the resource ID and phase ID, and changes the min UE groups, which may result in mixed services in same WUS resource. The first method may have a potential impact on ungrouped WUS UEs if a larger number of UE groups move into the ungrouped WUS resource and ungrouped WUS as the common WUS will wake up ungrouped and group WUS UEs together. The second method may be used to maintain the number of UE groups in one WUS resource.

In some aspects, using first method or second method may be based on whether ungrouped WUS is configured or not, or ungrouped WUS is configured as common WUS for group WUS in the WUS resource#<NUM> or not. For example, if ungrouped WUS is not configured as common WUS for group WUS in the WUS resource#<NUM>, the first method is used; otherwise, the second method is used. In some aspects, using the first method or second method may be based on whether service-based UE grouping is used for group WUS or not. For example, if service-based UE grouping is used for group WUS, the first method is used; otherwise, the second method is used.

Alternatively, the first method can be defined based on the PO index as <MAT>
and the second method can be defined based on the PO index as <MAT> where.

When the offset = <NUM>, the UE group may monitor the m-th WUS resource at the i-th PO with m=MOD(m0+i,M), where m0 is the initial WUS resource index for the UE group. For example, when M = <NUM>,.

In instances where the UE changes the monitored WUS resource, as shown above, the WUS sequence detected by the UE may change or remain the same. In some aspects, the WUS sequence is changed when the UE group monitors a different WUS resource. When the ungrouped WUS is configured, UEs that support ungrouped WUS may only detect ungrouped WUS sequence in the WUS resource #<NUM>. The group WUS sequences in WUS resource #<NUM> may use the same scrambling sequence as the ungrouped WUS sequence but differentiated by phase shifts, e.g., w_( UE_group_index)(m') = w(m')exp(j2πgm/G), where w(m') is the sequence for ungrouped WUS sequence and exp(j2πgm/G) is the phase shift with G = <NUM>, g = <NUM>*(UE_group_index+<NUM>), <NUM> ≤ UE_group_index ≤ <NUM> and g=<NUM> for common WUS sequence for the UEs monitoring the same WUS resource. When UEs that support grouping alternate the monitored WUS resource, the WUS sequence may use the scrambling sequence associated with a different WUS resource index.

In instances where the WUS sequence is not changed for the UE group, and is the same for all alternating WUS resources, the same WUS sequence may be allocated for the UE group regardless of which WUS resource is monitored. If UEs that do not support grouping are not monitoring the ungrouped WUS sequence, then the group WUS sequence may be pre-allocated to different UE groups.

In some instances, all of the UE groups in the same WUS resource may alternate the monitored WUS resource index. To alternate the monitored WUS resource index, the UE's within a particular UE group may monitor for the WUS using a scrambling sequence that changes based on the WUS resource ID to be monitored. The phase shift of the WUS group sequence may not change when the UE groups monitor different WUS resources. The phase shift may be based on a UE group. For example, the phase shift (e.g., g = <NUM>*(UE_group_index + <NUM>)) may be configured to differentiate the WUS sequence in the same WUS resource with the UE_group_index = {<NUM>,. In an example, the scrambling sequence may be {<NUM>, -<NUM>, j, -j} with a <NUM>-bit scrambling initialization seed, which may be determined based on the WUS resource ID m = {<NUM>, <NUM>, <NUM>, <NUM>}. Thus, all UE groups may be alternated in the same WUS resource together such that only the scrambling sequence (e.g., {<NUM>, -<NUM>, j, -j}) is changed based on the monitored WUS resource index, while keeping the phase shift, which is based on the group ID in the WUS resource, for the group WUS sequence the same. These aspects may allow for a reduction of complexity for WUS sequence generation.

In some instances a common WUS sequence may be configured. If a common WUS sequence is configured, the common WUS sequence may be different based on the monitored WUS resource ID. For example, if alternating to a legacy WUS resource with m=<NUM>, the common WUS sequence may be configured as the legacy WUS resource (e.g., g=<NUM>, m=<NUM>) or may be configured as the non-legacy WUS sequence (e.g., phase g=<NUM>*<NUM>, m=<NUM>). In some instances, when alternating to the non-legacy WUS resource with m><NUM>, the common WUS sequence may be the non-legacy common WUS sequence having a phase g=<NUM>*<NUM>, and the value of m may be determined based on the WUS resources available. In some instances, for example as shown in the diagram <NUM> of <FIG>, there may be <NUM> UE groups allocated into resources #<NUM> and #<NUM>, such that M = <NUM> WUS resources in total. At a first point in time, e.g., a first monitoring occasion, the first resource (e.g., #<NUM>) may be used by UE groups <NUM>~<NUM> to monitor for a WUS with the remaining UE groups <NUM>~<NUM> monitoring the second resource (e.g., #<NUM>) for a WUS. For example, for the initial PO <NUM> of <FIG> (e.g., PO(t0)) the UE group <NUM>~<NUM> may monitor the #<NUM> resource while the remaining UE groups <NUM>~<NUM> monitor the #<NUM> resource. In the next PO <NUM> of <FIG> (e.g., PO(t1)), when the UE groups alternate to monitoring a different resource for the WUS, the UE groups <NUM>~<NUM> may alternate and monitor the resource #<NUM>, while the UE group <NUM>~<NUM> may alternate and monitor the resource #<NUM>. A corresponding amount of UE groups (e.g., UE groups <NUM>~<NUM>) may alternate to monitor the resource #<NUM> when different resources have been configured to have a different number of UE groups. In the example of <FIG>, only UE groups <NUM>~<NUM> out of groups <NUM>-<NUM> alternated to monitor the resource #<NUM>. The phase shift may be kept the same when alternating or hopping between resources.

A UE group may alternate or hop among the WUS resources. Such hopping among WUS resources may be explicitly or implicitly enabled for the UEs in the UE group. In some instances, the UE group alternating or hopping among the WUS resources may be implicitly enabled when, for example, M><NUM>, which may enable UE group alternating among M WUS resources for group WUS. Therefore, a UE within the UE group may determine, in an implicit manner, that the UE should monitor for the WUS by hopping or alternating among WUS resources based on the number of WUS resources.

A UE may determine to perform alternating or hopping among WUS resources when monitoring for a WUS based on an explicit indication from a base station. For example, a WUS resource pattern configuration may be indicated by a SIB. For example, in instances where m=<NUM> is allocated for group WUS, then <MAT> with m=<NUM>~M-<NUM> and M=<NUM>, <NUM> or <NUM> may be used for alternating the UE group.

In some instances, as shown in the diagram <NUM> of <FIG>, for NB-IoT where M=<NUM>, the resources #<NUM> and #<NUM> may be used for alternating the UE group. In some instances, for MTC where M=<NUM>, <NUM>, or <NUM>, the resources #<NUM> and #<NUM> may be used for alternating the UE group when M=<NUM>; the resources #<NUM>, #<NUM>, #<NUM> may be used for alternating the UE group when M=<NUM>; or the resources #<NUM>, #<NUM>, #<NUM>, #<NUM> may be used for alternating the UE group when M=<NUM>. In some instances if the legacy WUS sequence is not configured as a common WUS sequence, then there is no impact. However, in instances where the legacy WUS sequence is configured as a common WUS sequence there may be a negative impact when more UE groups are moved into legacy WUS resource sharing with the legacy WUS, and the changing (e.g., alternating or hopping) of the monitored WUS resource per PO may reduce the probability of such an occurrence.

In some instances, where m=<NUM> is not allocated for group WUS, then WUS resource ID <MAT> with m=<NUM>~M-<NUM> and M=<NUM> or <NUM> may be used for alternating UE groups.

In some instances, as shown in the diagram <NUM> of <FIG>, for NB-IoT there may be only <NUM> WUS resource and alternating or hopping may not be enabled. In some instances, for MTC where M=<NUM> or <NUM>, the resources #<NUM> or #<NUM> may be used for alternating the UE group when M=<NUM>, or the resources #<NUM>, #<NUM>, or #<NUM> may be used for alternating the UE group when M=<NUM>. In the example of diagram <NUM> of <FIG>, since the #<NUM> resource is not allocated for group WUS, then the UE groups may only alternate between #<NUM>, #<NUM>, or #<NUM>.

Further enhancement may be provided if service-based grouping is used for group WUS. Assuming there are S types of services (each service associated to a subset of groups), it would be better to alternate the UE groups that belong to the same service type s (e.g., with similar paging probability) among the corresponding WUS resources, while not alternating the UE groups with different services. In some aspects, all of the UE groups per WUS resource may belong to the same service type s. There may be more than one WUS resource that belongs to the same service type s. The first method may alternate all UE groups per WUS resource together belong to the same service type s (change WUS resource ID only), as illustrated as
<MAT>
where.

with Tmax,s and Tmin,s to be indicated in SIB respectively or Tmax,s and Tmin,s to be predefined as the maximum and minimum value of the possible UE-specific DRX cycles respectively.

The second method is to alternate only minimum number of UE groups based on the UE group gx,s belong to same service type s , as illustrated as <MAT>
where.

<FIG> is a diagram <NUM> illustrating transmission between a base station and a UE. The diagram <NUM> includes a UE <NUM> and a base station <NUM>. In some aspects, the base station <NUM>, at <NUM>, may group one or more UEs in a UE group. The base station <NUM> may transmit, to one or more UEs in the UE group, an allocation of resources assigned to the one or more UEs in the UE group. The allocation of resources may comprise a group WUS resource within a set of WUS resources associated with a PO. The set of WUS resources may include a ungrouped WUS, where the location of the group WUS may be based on a frequency location of the ungrouped WUS. In some aspects, the location of the group WUS resource may be based on at least one of the ungrouped WUS having the frequency location in a first resource block and a second resource block of a six resource block bandwidth, the ungrouped WUS having the frequency location in a third resource block and a fourth resource block of the six resource block bandwidth, or the ungrouped WUS having the frequency location in a fifth resource block and a sixth resource block of the six resource block bandwidth.
