Description

WIRELESS DEVICE, NETWORK NODE, AND METHODS PERFORMED THEREBY, FOR HANDLING TRANSMISSION OF DATA

TECHNICAL FIELD

The present disclosure relates generally to a wireless device and methods performed thereby for handling transmission of data to a network node. The present disclosure further relates generally to a network node, and methods performed thereby for handling transmission of data from a wireless device.

BACKGROUND

Wireless devices within a wireless communications network may be e.g., User Equipments (UE), stations (STAs), mobile terminals, wireless terminals, terminals, and/or Mobile Stations (MS). Wireless devices are enabled to communicate wirelessly in a cellular communications network or wireless communication network, sometimes also referred to as a cellular radio system, cellular system, or cellular network. The communication may be performed e.g., between two wireless devices, between a wireless device and a regular telephone and/or between a wireless device and a server via a Radio Access Network (RAN) and possibly one or more core networks, comprised within the wireless communications network. Wireless devices may further be referred to as mobile telephones, cellular telephones, laptops, or tablets with wireless capability, just to mention some further examples. The wireless devices in the present context may be, for example, portable, pocket-storable, hand-held, computer-comprised, or vehicle-mounted mobile devices, enabled to communicate voice and/or data, via the RAN, with another entity, such as another terminal or a server.

The wireless communications network covers a geographical area which may be divided into cell areas, each cell area being served by a network node, which may be an access node such as a radio network node, radio node or a base station, e.g., a Radio Base Station (RBS), which sometimes may be referred to as e.g., gNB, evolved Node B (“eNB”), “eNodeB”, “NodeB”, “B node”, Transmission Point (TP), or BTS (Base Transceiver Station), depending on the technology and terminology used. The base stations may be of different classes such as e.g., Wide Area Base Stations, Medium Range Base Stations, Local Area Base Stations, Home Base Stations, pico base stations, etc... , based on transmission power and thereby also cell size. A cell is the geographical area where radio coverage is provided by the base station or radio node at a base station site, or radio node site, respectively. One base station, situated on the base station site, may serve one or several cells. Further, each base station may support one or several communication technologies. The base stations communicate over the air interface operating on radio frequencies with the terminals within range of the base stations. The wireless communications network may also be a non-cellular system, comprising network nodes which may serve receiving nodes, such as wireless devices, with serving beams. In 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), base stations, which may be referred to as eNodeBs or even eNBs, may be directly connected to one or more core networks. In the context of this disclosure, the expression Downlink (DL) may be used for the transmission path from the base station to the wireless device. The expression Uplink (UL) may be used for the transmission path in the opposite direction i.e., from the wireless device to the base station.

The standardization organization 3GPP is currently in the process of specifying a New Radio Interface called NR or 5G-UTRA, as well as a Fifth Generation (5G) Packet Core Network, which may be referred to as Next Generation (NG) Core Network, abbreviated as NG- CN, NGC or 5G CN.

Internet of Things (loT)

The Internet of Things (loT) may be understood as an internetworking of communication devices, e.g., physical devices, vehicles, which may also referred to as "connected devices" and "smart devices", buildings and other items — embedded with electronics, software, sensors, actuators, and network connectivity that may enable these objects to collect and exchange data. The loT may allow objects to be sensed and/or controlled remotely across an existing network infrastructure.

"Things," in the loT sense, may refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, electric clams in coastal waters, automobiles with built-in sensors, DNA analysis devices for environmental/food/pathogen monitoring, or field operation devices that may assist firefighters in search and rescue operations, home automation devices such as the control and automation of lighting, heating, e.g. a “smart” thermostat, ventilation, air conditioning, and appliances such as washer, dryers, ovens, refrigerators or freezers that may use telecommunications for remote monitoring. These devices may collect data with the help of various existing technologies and then autonomously flow the data between other devices.

It is expected that in a near future, the population of loT devices will be very large. Various predictions exist, among which one assumes that there will be >60000 devices per square kilometer, and another assumes that there will be 1000000 devices per square kilometer. A large fraction of these devices is expected to be stationary, e.g., gas and electricity meters, vending machines, etc.

Machine Type Communication (MTC)

Machine Type Communication (MTC) has in recent years, especially in the context of the Internet of Things (loT), shown to be a growing segment for cellular technologies. An MTC device may be a communication device, typically a wireless communication device or simply user equipment, that is a self and/or automatically controlled unattended machine and that is typically not associated with an active human user in order to generate data traffic. An MTC device may be typically simpler, and typically associated with a more specific application or purpose, than, and in contrast to, a conventional mobile phone or smart phone. MTC involves communication in a wireless communication network to and/or from MTC devices, which communication typically may be of quite different nature and with other requirements than communication associated with e.g. conventional mobile phones and smart phones. In the context of and growth of the loT, it is evident that MTC traffic will be increasing and thus needs to be increasingly supported in wireless communication systems.

Small data transmission

NR supports Radio Resource Control (RRC)JNACTIVE state and UEs with infrequent, e.g., periodic and/or non-periodic, data transmission may be generally maintained by the network in the RRCJNACTIVE state. Until Rel-16, the RRCJNACTIVE state does not support data transmission. Hence, the UE has to resume the connection, that is, move to RRC_CONNECTED state for any DL, that is Mobile Terminated (MT), and UL, that is, Mobile Originated (MO) data. Connection setup and subsequently release to INACTIVE state may happen for each data transmission however small and infrequent the data packets may be. This results in unnecessary power consumption and signalling overhead.

Specific examples of small and infrequent data traffic may include the following use cases. For smartphone applications: traffic from instant messaging (IM) services, e.g., WhatsApp, QQ, WeChat etc, heart-beat/keep-alive traffic from IM/email clients and other apps, push notifications from various applications. For non-smartphone applications: traffic from wearables, e.g., periodic positioning information etc, sensors, e.g., industrial wireless sensor networks transmitting temperature, pressure readings periodically or in an event triggered manner etc, smart meters and smart meter networks sending periodic meter readings.

As noted in 3GPP TS 22.891 v14.2.0, the NR system may be required to: be efficient and flexible for low throughput short data bursts, support efficient signalling mechanisms, e.g. signalling may be less than payload, and reduce signalling overhead in general.

Signalling overhead from INACTIVE state UEs for small data packets is a general problem and will become a critical issue with more UEs in NR not only for network performance and efficiency, but also for the UE battery performance. In general, any device that has intermittent small data packets in INACTIVE state may benefit from enabling small data transmission in INACTIVE.

The key enablers for small data transmission in NR, namely the INACTIVE state, 2-step, 4-step Random Access Channel (RACH) and configured grant type-1 have already been specified as part of Rel-15 and Rel-16.

A/R frame structure Similar to LTE, NR may use Orthogonal Frequency Division Multiplexing (OFDM) in the downlink, that is, from a network node, gNB, eNB, or base station, to a user equipment or UE. The basic NR physical resource over an antenna port may thus be seen as a time-frequency grid as illustrated in Figure 1 , where a resource block (RB) in a 14-symbol slot is shown. A resource block may be understood to correspond to 12 contiguous subcarriers in the frequency domain. Resource blocks may be numbered in the frequency domain, starting with 0 from one end of the system bandwidth. Each resource element may be understood to correspond to one OFDM subcarrier during one OFDM symbol interval.

Different subcarrier spacing values may be supported in NR. The supported subcarrier spacing values, also referred to as different numerologies, may be given by Af=(15x2^Ap) kHz, where p e (0,1 , 2, 3, 4). Af=15 kHz may be understood to be the basic, or reference, subcarrier spacing that may also be used in LTE.

In the time domain, downlink and uplink transmissions in NR may be organized into equally-sized subframes of 1ms each, similar to LTE. A subframe may be further divided into multiple slots of equal duration. The slot length for subcarrier spacing Af=(15x2^A p) kHz may be 1/2^A p ms. There may only be one slot per subframe for Af=15kHz and a slot may consist of 14 OFDM symbols.

Downlink transmissions may be dynamically scheduled, that is, in each slot, the gNB may transmit downlink control information (DCI) about which UE data may have to be transmitted to and which resource blocks in the current downlink slot the data may have to be transmitted on. This control information may be typically transmitted in the first one or two OFDM symbols in each slot in NR. The control information may be carried on the Physical Control Channel (PDCCH), and data may be carried on the Physical Downlink Shared Channel (PDSCH). A UE may first detect and decode PDCCH, and if a PDCCH is decoded successfully, it may then decode the corresponding PDSCH based on the downlink assignment provided by decoded control information in the PDCCH.

In addition to PDCCH and PDSCH, there may be also other channels and reference signals transmitted in the downlink, including Synchronization Signal and PBCH block (SSB), Channel State Information Reference Signal (CSI-RS), etc.

Uplink data transmissions, carried on Physical Uplink Shared Channel (PUSCH), may also be dynamically scheduled by the gNB by transmitting a DCI. The DCI, which may be transmitted in the DL region, may always indicate a scheduling time offset so that the PUSCH may be transmitted in a slot in the UL region.

Beamforming is expected to be widely applied for NR operation at least in mm-wave bands for both transmission and reception. For UL transmission, a spatial relation may need to be established and understood by both UE and gNB before transmission in the UL may be conducted. A spatial relation may be defined between an UL channel/reference signal, such as PLISCH, PLICCH, and Sounding Reference Signal (SRS) and either a DL reference signal, such as CSI-RS, SS/PBCH block, or another UL reference signal, such as SRS. If UL channel/signal A is spatially related to reference signal B, it may be understood to mean the UE may need to beamform A in the same way as it received/transmitted B, that is, by using a same spatial filter for A as it may be used to receive B. By establishing a spatial relation, the may UE get to know in which direction to beamform its transmission signal towards the targeted gNB, and the gNB may also understand how to tune its Receiver (RX) beam towards the beam or signal transmitted by the UE.

Primary synchronization signals (PSS) and secondary synchronization signals (SSS) and the Physical Broadcast Channel (PBCH) may be transmitted in a Synchronization Signal and PBCH block (SSB). The SSB transmission periodicity may be configured, but SSBs may also have different time locations within half-frames in the subframes where they may be transmitted - the SSBs with different time locations within half-frames may be transmitted in different spatial directions cf. using different beams. See for example TS 38.300, v. 16.3.0 section 5.2.4 and TS 38.212, v .16.3.0, section 4.1.

A/R small data transmissions in INACTIVE state

A new Work Item (Wl) RP-200954 ‘New Work Item on NR small data transmissions in INACTIVE state’ has been approved in 3GPP with the focus of optimizing the transmission for small data payloads by reducing the signaling overhead. The Wl contains the following objectives. This work item may be understood to enable small data transmission in RRC NACTIVE state as follows. For the RRC_IN ACTIVE state, and UL small data transmissions for Random Access Channel (RACH)-based schemes, that is, 2-step and 4-step RACH, this Wl may enable, first, a general procedure to enable User Plane (UP) data transmission for small data packets from INACTIVE state, e.g., using MSGA or MSG3, [RAN2], Second, the Wl may enable flexible payload sizes larger than the Rel-16 Common Control Channel (CCCH) message size that may be possible currently for INACTIVE state for MSGA and MSG3 to support UP data transmission in UL, actual payload size may be up to network configuration, [RAN2], Third, the Wl may enable context fetch and data forwarding, with and without anchor relocation, in INACTIVE state for RACH-based solutions [RAN2, RAN3], As a side note, the security aspects of the above solutions may have to be checked with SA3. For the RRCJNACTIVE state and transmission of UL data on pre-configured Physical Uplink Shared Channel (PUSCH) resources, this Wl may enable reusing the configured grant type 1 , when Time Alignment (TA) may be valid. First, the Wl may enable a general procedure for small data transmission over configured grant type 1 resources from INACTIVE state [RAN2], Second, this Wl may enable configuration of the configured grant typel resources for small data transmission in UL for INACTIVE state [RAN2],

For Narrow Band loT (NB-loT) and LTE-M, similar signaling optimizations for small data have been introduced through Rel-15 Early Data Transmission (EDT) and Rel-16 Preconfigured Uplink Resources (PUR). Somewhat similar solutions may be expected for NR with the difference that the Rel-17 NR Small Data is only to be supported for RRC INACTIVE state, may include also 2-step RACH based small data, and that it may need to also include regular complexity Mobile BroadBand (MBB) UEs. Both may be understood to support mobile originated (MO) traffic only.

Within the context of Small Data Transmission (SDT), the possibility of transmitting subsequent data has been discussed, meaning transmission of further segments of the data that cannot fit in the Msg3 Transport Block. Such segments of data may be transmitted either in RRC_CONNECTED, as in legacy after the 4-step RACH procedure has been completed, or they may be transmitted in RRCJNACTIVE, before the UE transitions to RRC_CONNECTED. In the former case, the transmission may be more efficient, as the gNB and UE may be appropriately configured based on the current UE channel conditions, while in the latter case several optimizations may not be in place yet, especially if the UE has moved while not connected, and also the transmission may collide with the transmission from other UEs, as the contention has not been resolved yet.

The Work Item has already started in 3GPP meeting RAN2#111-e, and the following relevant agreements have already been made [1], As a first agreement, small data transmission with Radio Resource Control (RRC) message may be supported as baseline for Random Access (RA)-based and Configured Grant (CG) based schemes. As a second agreement, the 2-step RACH or 4-step RACH may need to be applied to RACH based uplink small data transmission in RRC NACTIVE. As a third agreement, the uplink small data may be sent in MSGA of 2-step RACH or msg3 of 4-step RACH. As a fourth agreement, small data transmission may be configured by the network on a per Data Radio Bearer (DRB) basis. As a fifth agreement, a data volume threshold may be used for the UE to decide whether to do SDT or not. For Further Study (FFS) how to calculate data volume. As a sixth agreement, FFS if an “additional SDT specific” Reference Signal Received Power (RSRP) threshold may be further used to determine whether the UE should do SDT. As a seventh agreement, UL/DL transmission following UL SDT without transitioning to RRC_CONNECTED may be supported. As an eighth agreement, when a UE is in RRCJNACTIVE, it may be possible to send multiple UL and DL packets as part of the same SDT mechanism and without transitioning to RRC_CONNECTED on dedicated grant. FFS on details and whether any indication to network may be needed.

It may be noted that some of the mechanisms discussed in this document are already agreed, therefore they do not represent the object of the embodiments herein. They may be understood to serve the purpose of presenting a complete working solution.

In RAN2#112-e, the following agreements have been made. First, the configuration of configured grant resource for UE uplink small data transfer may be contained in the RRCRelease message. FFS if other dedicated messages may configure CG in INACTIVE CG. Configuration may be understood to be only type 1 CG with no contention resolution procedure for CG. Second, the configuration of configured grant resource may include one type 1 CG configuration. FFS if multiple configured CGs may be allowed. Third, a new Timing Advance (TA) timer for TA maintenance specified for configured grant based small data transfer in RRCJNACTIVE may need to be introduced. FFS on the procedure, the validity of TA, and how to handle expiration of TA timer. The TA timer may be configured together with the CG configuration in the RRCRelease message. Fourth, the configuration of configured grant resource for UE small data transmission may valid be only in the same serving cell. FFS for other CG validity criteria, e.g., timer, UL/Supplementary UL(SIIL) aspect, etc. Fifth, the UE may use configured grant based small data transfer if at least the following criteria is fulfilled (1) user data is smaller than the data volume threshold; (2) configured grant resource is configured and valid; and (3) the UE has a valid TA. FFS for the candidate beam criteria. Sixth, from the RAN2 point of view, an association between CG resources and SSBs may be required for CG-based SDT. FFS up to RAN1 how the association may be configured or provided to the UE. Send an LS to RAN1 to start the discussion on how the association can be made. Mention that one option RAN2 considered was explicit configuration with RRC Release message. Seventh, a Synchronization Signal Reference Signal Received Power (SS-RSRP) threshold may be configured for SSB selection. A UE may select one of the SSB with SS-RSRP above the threshold and select the associated CG resource for UL data transmission.

In the latest discussions, it has been proposed that the UE may be configured with a CG which may have multiple associations, that is, different CG occasions may have associations to different SSBs.

Two types of Configured Grant (CG) UL transmission schemes have been supported in NR since Rel-15, referred as CG Typel and CG Type2 in the standard. The major difference between these two types of CG transmission may be understood to be that for CG Typel , an uplink grant may be provided by RRC configuration and activated automatically, while in the case of CG Type2, the uplink grant may be provided and activated via L1 signaling, that is, by an UL DCI with Cyclic Redundancy Checksum (CRC) scrambled by Configured Scheduling- Radio Network Temporary Identifier (CS-RNTI). In both cases, the spatial relation used for PUSCH transmission with Configured Grant may be indicated by the uplink grant, either provided by the Radio Resource Control (RRC) configuration, or by an UL DCI. The uplink grant may contain an srs-Resourcelndicator field, pointing to one of the SRS resources in the SRS resource configuration, which may be configured in-turn with a spatial relation to a DL Reference Signal (RS), SSB or CSI-RS, or another SRS resource. With the SRS resource indicator in the uplink grant and the RRC SRS resource configuration, PLISCH with Configured Grant may be supposed to be transmitted with the same precoder or beamforming weights as the one used for the transmission of the reference SRS.

Configured scheduling

In NR, configured scheduling may be used to allocate semi-static periodic assignments or grants for a UE. For uplink, there may be two types of configured scheduling schemes: Type 1 and Type 2. For Type 1, configured grants may be configured via RRC signaling only. For Type 2, a similar configuration procedure as Semi-Persistent Scheduling (SPS) UL in LTE was defined, that is, some parameters may be preconfigured via RRC signaling, and some physical layer parameters may be configured via a Medium Access Control (MAC) scheduling procedure. The detail procedures may be found in 3GPP TS 38.321 v. 16.2.1 clause 5.8.2 [1],

Like for SPS in LTE, the CG periodicity may be RRC configured, and this may be specified in the ConfiguredGrantConfig Information Element (IE). Different periodicity values may be supported in NR depending on the subcarrier spacing (SCS). For example, for 15 and 30 kHz SCS, the following periodicities may be supported, expressed in a number of OFDM symbols. For 15kHz SCS, 2, 7, and n*14 OFDM symbols, where n e {1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640}. For 30kHz SCS, 2, 7, and n*14 OFDM symbols, where n e {1 , 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 640, 1280}. For Typel configured grants, in addition to the periodicity, the time domain allocation of PUSCH may be configured purely via RRC signalling. timeDomainOffset may provide a slot offset with respect to Subbframe Number (SFN) 0. timeDomainAllocation may provide an index into a table of 16 possible combinations of PUSCH mapping type (TypeA or TypeB), start symbol S for the mapping (S = OFDM symbol 0, 2, 4, or 8 within a slot), and length L of the mapping (L = 4, 6, 8, 10, 12, or 14 OFDM symbols).

The detailed configuration details of the RRC specification, that is, 3GPP TS 38.331 , v. 16.2.0, Rel. 16) for configured grant is illustrated below. Table 1 shows the Rel-16 ConfiguredGrantConfig IE in the RRC specification.

Table 1

A UE may be provided with multiple active configured grants for a given Bandwidth Part (BWP) in a serving cell. The introduction of multiple configured grants may serve at least for enhancing reliability and reducing latency of critical services.

Configured UL with repetition

Repetition of a Transport Block (TB) may also be supported in NR, and the same resource configuration may be used for K repetitions for a TB including the initial transmission. The higher layer configured parameters repK and repK-RV may define the K repetitions to be applied to the transmitted transport block, and the redundancy version pattern to be applied to the repetitions. For the nth transmission occasion among K repetitions, n=1 , 2, ... , K, it may be associated with (mod(n-1 ,4)+1)th value in the configured RV sequence. The initial transmission of a transport block may start at: a) the first transmission occasion of the K repetitions if the configured RV sequence may be {0,2,3, 1}, b) any of the transmission occasions of the K repetitions that may be associated with RV=0 if the configured RV sequence may be {0,3, 0,3}, or c) any of the transmission occasions of the K repetitions if the configured RV sequence is {0,0, 0,0}, except the last transmission occasion when K=8.

For any RV sequence, the repetitions may be required to be terminated after transmitting K repetitions, or at the last transmission occasion among the K repetitions within the period P, or when an UL grant for scheduling the same TB may be received within the period P, whichever may be reached first. The UE may not be expected to be configured with the time duration for the transmission of K repetitions larger than the time duration derived by the periodicity P.

For both Type 1 and Type 2 PLISCH transmissions with a configured grant, when the UE is configured with repK > 1 , the UE may be required to repeat the TB across the repK consecutive slots applying the same symbol allocation in each slot. If the UE procedure for determining slot configuration, as defined in subclause 11.1 of TS 38.213, v. 16.3.0, determines symbols of a slot allocated for PUSCH as downlink symbols, the transmission on that slot may be omitted for multislot PUSCH transmission.

In spite of its benefits, existing methods to perform Small Data transmissions may result in a waste of resources or missed communications between transmitter and receiver.

SUMMARY

As part of the development of embodiments herein, one or more challenges with the existing technology will first be identified and discussed.

Uplink beam misalignment between gNB and UE may occur. For configured grants this may be understood to mean that the UE may be configured with a configured grant that is not valid for the current best beam, so the gNB may not listen to the transmission, or grant, occasion and the beam direction. The gNB with analog beamforming capability may only listen to UL transmission in one direction, per antenna panel, at a time.

For SDT, a UE may be configured with CG for SDT in Inactive, which may be spatially related to an SSB. However, if the UE moves so that the current SSB RSRP is no longer sufficient for acceptable transmission performance, there is currently no solution for how to handle this except for stop using the CG configuration. Another alternative may be to use a CG configuration for SDT in Inactive which may be spatially related to several SSBs, that is, different CG transmission occasions may be associated with different SSBs, and the UE may select the transmission occasion corresponding to the best SSB, that is, the SSB which may have the highest RSRP. However, this alternative may give a great deal of overhead since the UE may only use one of the spatial associations, meaning that the other CG transmission occasions will not be used when the UE is stationary.

It is an object of embodiments herein to improve the handling of transmission of data to a network node.

According to a first aspect of embodiments herein, the object is achieved by a method, performed by a wireless device. The method is for handling transmission of data to a network node. The wireless device operates in a wireless communications network. The wireless device sends data to the network node during an inactive state of the wireless device. The wireless device sends the data on one or more first resources. The one or more first resources are selected from a set of resources configured to be for transmission occasions by the wireless device. The set of resources have a correspondence to a plurality of beams or reference signals transmitted by the network node. The wireless device then sets the unselected remaining resources of the set as inactive.

According to a second aspect of embodiments herein, the object is achieved by a method, performed by a network node. The method is for handling transmission of data from the wireless device. The network node operates in the wireless communications network. The network node receives the data from the wireless device during the inactive state of the wireless device. The network node receives the data on the one or more first resources. The network node then determines which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device, have been one of: i) the one or more first resources selected by the wireless device to send the data, ii) unused, unselected remaining resources, or iii) set as inactive by the wireless device. The set of resources have the correspondence to the plurality of beams or reference signals transmitted by the network node.

According to a third aspect of embodiments herein, the object is achieved by the wireless device, for handling transmission of data to the network node. The wireless device is configured to operate in the wireless communications network. The wireless device is further configured to send data to the network node during the inactive state of the wireless device. The wireless device is configured to send the data on the one or more first resources. The one or more first resources are configured to be selected from the set of resources configured to be for transmission occasions by the wireless device. The set of resources are configured to have the correspondence to the plurality of beams or reference signals configured to be transmitted by the network node. The wireless device is further configured to set the unselected remaining resources of the set as inactive.

According to a fourth aspect of embodiments herein, the object is achieved by the network node, for handling transmission of data from the wireless device. The network node is configured to operate in the wireless communications network. The network node is further configured to receive the data from the wireless device during the inactive state of the wireless device, on the one or more first resources. The network node is configured to determine which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device, have been one of: i) the one or more first resources configured to be selected by the wireless device to send the data, ii) unused, unselected remaining resources, or iii) set as inactive by the wireless device. The set of resources are configured to have the correspondence to the plurality of beams or reference signals configured to be transmitted by the network node.

By sending the data to the network node on the selected one or more first resources and setting the unselected remaining resources of the set as inactive, the wireless device may enable the network node to avoid having to monitor UL transmissions from the wireless device, e.g., CG- SDT, in the whole set of resources configured to be for transmission occasions by the wireless device, e.g., all configured beams, which may be understood to be processing demanding. For example, the network node may then be enabled to refrain from having to perform blind decoding on these resources.

Furthermore, by setting the unselected remaining resources of the set as inactive, the wireless device may enable that the resources may be released. Hence, the wireless device may enable to reduce the resources that may be needed to perform data transmissions, e.g., CG transmissions, in inactive state when transmission circumstances may change, such as when the best beam, e.g., SSB, may change. The network node may thereby be enabled to use resources in the wireless communications network more efficiently.

By the network node determining which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device, have been selected to send the data by the wireless device and which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device, have been unused, unselected remaining resources, or set as inactive by the wireless device, the network node may then be enabled to avoid having to monitor UL transmissions from the wireless device, e.g., CG- SDT, in the whole set of resources configured to be for transmission occasions by the wireless device, e.g., all configured beams, which may be understood to be processing demanding.

By the network node determining which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device, have been unused, unselected remaining resources, or set as inactive by the wireless device, the network node may be able to know which resources may be available to be assigned to one or more wireless devices. Hence, the network node may thereby be enabled to use resources in the wireless communications network more efficiently, increasing the capacity of the wireless communications network, as well as decreasing its latency.

Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. Embodiments herein may be generally understood to relate to an SSB change for CG SDT operation in Inactive state.

To overcome the problem with high overhead of CG configurations with multiple SSB associations, according to embodiments herein, only the association used when the UE may do its first CG transmission may be kept and the other may be released. This may be understood to mean that when the UE may do its first transmission on the CG, it may select the CG transmission occasion that may have the best SSB association, that is, corresponding to the SSB with highest SSB-RSRP. The selection of the best SSB association and CG transmission occasion may trigger the UE to consider the CG transmission occasion corresponding to other SSBs as not valid and therefore they may be inactivated. In the same fashion, the gNB may assign these resources to other UEs.

In case the UE may later discover that some other SSB association may be better, it may signal this to the gNB which then may reconfigure the resources.

Some of the embodiments contemplated will now be described more fully hereinafter with reference to the accompanying drawings, in which examples are shown. In this section, the embodiments herein will be illustrated in more detail by a number of exemplary embodiments. Other embodiments, however, are contained within the scope of the subject matter disclosed herein. The disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art. It should be noted that the exemplary embodiments herein are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments.

Figure 2 depicts two non-limiting examples of a wireless network or wireless communications network 100, sometimes also referred to as a wireless communications system, cellular radio system, or cellular network, in which embodiments herein may be implemented. The wireless communications network 100 may be a 5G system, 5G network, or Next Gen System or network. In other examples, the wireless communications network 100 may instead, or in addition, support other technologies such as, for example, Long-Term Evolution (LTE), e.g. LTE-M, LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), LTE Half-Duplex Frequency Division Duplex (HD-FDD), LTE operating in an unlicensed band, such as LTE LAA, eLAA, feLAA and/or MulteFire. Yet in other examples, the wireless communications network 100 may support other technologies such as, for example Wideband Code Division Multiple Access (WCDMA), Universal Terrestrial Radio Access (UTRA) TDD, Global System for Mobile communications (GSM) network, GSM/Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network (GERAN) network, Ultra-Mobile Broadband (UMB), EDGE network, network comprising of any combination of Radio Access Technologies (RATs) such as e.g. Multi-Standard Radio (MSR) base stations, multi-RAT base stations etc., any 3rd Generation Partnership Project (3GPP) cellular network, WiFi networks, Worldwide Interoperability for Microwave Access (WiMax), or any cellular network or system, such as a younger system than 5G supporting equivalent functionality. The wireless communications network 100 may typically be support MTC, eMTC, loT and/or NB-loT. Thus, although terminology from 5G/NR and LTE may be used in this disclosure to exemplify embodiments herein, this should not be seen as limiting the scope of the embodiments herein to only the aforementioned system.

The wireless communications network 100 may comprise a plurality of network nodes, whereof a network node 110 is depicted in the non-limiting example of Figure 2. The network node 110 is a radio network node. That is, a transmission point such as a radio base station, for example a gNB, an eNB, an eNodeB, or a Home Node B, a Home eNode B, or any other network node with similar features capable of serving a user equipment, such as a wireless device or a machine type communication device, in the wireless communications network 100. In some examples, such as that depicted in Figure 2 b, the network node 110 may be a distributed node, and may partially perform its functions in collaboration with a virtual node 116 in a cloud 115.

The wireless communications network 100 may cover a geographical area, which in some embodiments may be divided into cell areas, wherein each cell area may be served by a radio network node, although, one radio network node may serve one or several cells. In the example of Figure 2, the network node 110 serves a cell 120. The network node 110 may be of different classes, such as, e.g., macro eNodeB, home eNodeB or pico base station, based on transmission power and thereby also cell size. In some examples, the network node 110 may serve receiving nodes with serving beams. The radio network node may support one or several communication technologies, and its name may depend on the technology and terminology used. Any of the radio network nodes that may be comprised in the communications network 100 may be directly connected to one or more core networks.

A plurality of wireless devices may be located in the wireless communication network 100, whereof a wireless device 130 and one or more other wireless devices 140 are depicted in the non-limiting example of Figure 2. Any of the wireless device 130 and the one or more other wireless devices 140 comprised in the wireless communications network 100 may be a wireless communication device such as a 5G UE, or a UE, which may also be known as e.g., mobile terminal, wireless terminal and/or mobile station, a mobile telephone, cellular telephone, or laptop with wireless capability, just to mention some further examples. Any of the wireless device 130 and the one or more other wireless devices 140 comprised in the wireless communications network 100 may be, for example, portable, pocket-storable, hand-held, computer-comprised, or a vehicle-mounted mobile device, enabled to communicate voice and/or data, via the RAN, with another entity, such as a server, a laptop, a Personal Digital Assistant (PDA), or a tablet, Machine-to-Machine (M2M) device, a sensor, loT device, NB-loT device, device equipped with a wireless interface, such as a printer or a file storage device, modem, or any other radio network unit capable of communicating over a radio link in a communications system. Any of the wireless device 130 and the one or more other wireless devices 140 comprised in the wireless communications network 100 may be enabled to communicate wirelessly in the wireless communications network 100. The communication may be performed e.g., via a RAN, and possibly the one or more core networks, which may be comprised within the wireless communications network 100.

The wireless device 130 may be configured to communicate within the wireless communications network 100 with the network node 110 over a first link 141 , e.g., a radio link. The network node 110 may be configured to communicate within the wireless communications network 100 with the virtual network node 116 over a second link 142, e.g., a radio link or a wired link. Any of the one or more other wireless devices 140 may be configured to communicate within the wireless communications network 100 with the network node 110 over a respective first link, e.g., a radio link, which are not depicted in Figure 2 to simplify the figure.

Several embodiments are comprised herein. It should be noted that the examples herein are not mutually exclusive. Components from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments.

More specifically, the following are embodiments related to a wireless device, such as the wireless device 130, e.g., a 5G UE or a UE, and embodiments related to a network node, such as the network node 110, e.g., a gNB or an eNB.

Embodiments of a method, performed by the wireless device 130, will now be described with reference to the flowchart depicted in Figure 3. The method may be understood to be for handling transmission of data to the network node 110. The wireless device 130 operates in the wireless communications network 100.

In some embodiments, the wireless communications network 100 may support at least one of: New Radio (NR), Long Term Evolution (LTE), LTE for Machines (LTE-M), enhanced Machine Type Communication (eMTC), and Narrow Band Internet of Things (NB-loT).

In some examples, data may be “Small Data”.

The first method may comprise some of the following actions. In some embodiments, all the actions may be performed. Components from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments. All possible combinations are not described to simplify the description. A non-limiting example of the method performed by the wireless device 130 is depicted in Figure 3. In Figure 3, optional actions are represented with dashed lines. The actions may be performed in a different order than that depicted in Figure 3.

Action 301

In this Action 301, the wireless device 130 may obtain a configuration. The configuration may configure a set of resources to be for transmission occasions by the wireless device 130. Each of resources may correspond to a configured grant, e.g., CG. The resources may be transmission occasions.

The set of resources may have a correspondence to a plurality of beams or reference signals transmitted by the network node 110. The reference signals may be, e.g., Synchronization Signal Blocks (SSB), which may be transmitted by the network node 110. Obtaining in this Action 301 may comprise, retrieving or fetching from a memory, and/or receiving, e.g., from the network node 110, e.g., via the first link 141.

The configuration may be obtained from the network node 110, in at least one of: a) a first message releasing a connection between the network node 110 and the wireless device 130, and b) a second dedicated message. According to the first option, the configuration may be given in the RRCRelease message that may be sent to the wireless device 130 while in connected state to put the wireless device 130 into Inactive state, or alternatively, according to the second option, in another dedicated RRC message, for example while the wireless device 130 may be in RRC_CONNECTED.

In a first group of examples, in accordance with this Action 301 , the set of configured resources may be configured for the wireless device 130, where different CG transmission occasions may have different SSB associations.

In some embodiments, one of the following options may apply. According to a first option, the configuration may specify that each of a plurality of transmission occasions may correspond to a respective beam or reference signal. According to a second option, a correspondence between each of the plurality of transmission occasions to a respective beam or reference signal may be specified by a respective configuration. According to this option, the configuration may comprise the respective configurations for all transmission occasions.

An example of two options of configuring CG resources are given later, in Figure 5.

By receiving the configuration in this Action 301 , the wireless device 130 may be enabled to associate a configured grant resource configuration with a single or multiple SSB(s) of the cell 120.

Action 302

In this Action 302, the wireless device 130 may receive a first indication from the network node 110. The first indication may indicate to inactivate second resources of the set. For example, in accordance with this Action 302, a CG resource may be inactivated due to an explicit release command in the DL, or an implicit release command, e.g., skipped n occasions, TA timer etc. This may be understood to be a new command, different than e.g., the legacy RRCRelease.

In some examples, the receiving in this Action 302 may be performed, e.g., via the first link 141.

In an alternative configuration, if multiple CG-SDT configurations are configured per SSB or beam, one of the configurations may be active, per the criterion based on which the configuration may be selected, and the other configurations may be considered ‘inactive’. In some embodiments, the wireless device 130 may receive the first indication before the wireless device 130 may perform Action 303, that is, before the wireless device 130 may select which resources it may perform transmission on. The wireless device 130 may then be enabled to perform a selection of which resources to use to transmit data to the network node 130 based on the received first indication. In other embodiment, this Action 302 may not necessarily be performed after Action 301 and before Action 303. It may be performed, for example, after Action 305 and before Action 306, as will be described later.

Action 303

In this Action 303, the wireless device 130 may select one or more first resources in the set, that is, the configured set of resources, based on one or more criteria.

Each of the one or more first resources may correspond to a configured grant (CG).

The wireless device 130 may determine, in accordance with this Action 303, if SDT using the CG may apply through estimation of some or all of TA, data volume and change in RSRP. The main problem to solve may only arise if a beam that may be configured may not be the best beam at RRCrelease, that is, when the wireless device 130 may be moved to Inactive state. Selection between multiple CG configurations may be done based on, e.g., priority configuration, the transmitted data size, configured RSRP threshold and/or other criteria.

In some embodiments, the one or more first resources may correspond to a beam. The one or more criteria may comprise the one or more first resources corresponding to the beam having the highest SS-RSRP, above a minimum threshold.

In some examples, the wireless device 130 may determine, in accordance with this Action 303, each time before performing the (CG) SDT, whether to use the CG PLISCH resources configured based on quality of the associated SSB.

For example, for the first transmission on the configured CG resources, the wireless device 130 may select the best CG resource, that is, the resource corresponding to the beam which may have the highest SS-RSRP, above a minimum threshold, on the configured carrier. As an alternative, several CG resources that may be above a threshold may be selected.

By selecting the one or more first resources in the set based on the one or more criteria in this Action 303, the wireless device 130 may be enabled to correct any potential uplink beam misalignment between the network node 110 and wireless device 130 that may have occurred. Therefore, the wireless device 130 may be enabled to prevent that the network node 110 may not listen to the transmission grant occasion and the beam direction. This is considering that, in some examples, the network node 110, if it has analog beamforming capability, may only listen to UL transmission in one direction, per antenna panel, at a time.

Additionally, by selecting the one or more first resources in the set based on the one or more criteria in this Action 303, the wireless device 130 may then be enabled to inactivate any unselected resources, thereby enabling that the network node may avoid having to monitor UL transmissions from the wireless device, e.g., CG-SDT, in the whole set of resources configured to be for transmission occasions by the wireless device, e.g., all configured beams, which may be understood to be processing demanding. For example, the network node may then be enabled to refrain from having to perform blind decoding on these resources.

Action 304

In this Action 304, the wireless device 130 may send a second indication to the network node 110. The second indication may indicate the selected one or more first resources. The wireless device 130 may be required to, in accordance with this Action 304, indicate the beam change.

The sending in this Action 304 may be performed, e.g., via the first link 141.

As an alternative to transmitting the indication of new best SSB using CG, the wireless device 130 may do a Random Access procedure for this purpose.

By, in this Action 304, sending the second indication to the network node 110, the wireless device 130 may enable the network node 110 to avoid having to monitor UL transmissions from the wireless device 130, e.g., CG-SDT, in all configured beams, which may be understood to be processing demanding. Hence, the wireless device 130 may enable the network node 110 to use resources in the wireless communications network 100 more efficiently.

Action 305

In this Action 305, the wireless device 130 sends data, e.g., first data, to the network node 110 during an inactive state of the wireless device 130. The inactive state may be, e.g., as defined in 5G or in a younger system having equivalent functionality. The expression during an/the inactive state may be understood to mean “while being in inactive state” or “while in inactive state”.

The first data may be user plane data.

The sending in this Action 305 is the on one or more first resources selected from the set of resources configured to be for transmission occasions by the wireless device 130.

The set of resources has the correspondence to the plurality of beams or reference signals transmitted by the network node 110. The reference signals may be, e.g., Synchronization Signal Blocks (SSB), which may be transmitted by the network node 110. The one or more first resources may be one or more transmission occasions, which may correspond to one or more beams, and/or one or more reference signals.

The one or more first resources may be time-frequency resources, e.g., radio resources. Each of the one or more first resources may correspond to a configured grant. The sending in this Action 305 may be performed with the proviso that a size of a buffer of the wireless device 130 may be smaller than a threshold. The buffer may be a buffer for transmission of the data, which may be referred to herein as a transmit buffer.

The threshold may be a maximum size of the buffer (BSmax), e.g., a maximum transmit buffer size.

The sending in this Action 305 may be performed, e.g., via the first link 141.

By sending the data to the network node 110on the selected one or more first resources, the wireless device 130 may enable the network node 110 to avoid having to monitor UL transmissions from the wireless device 130, e.g., CG-SDT, in the whole set of resources configured to be for transmission occasions by the wireless device, e.g., all configured beams, which may be understood to be processing demanding. Hence, the wireless device 130 may enable to reduce the resources that may be needed to perform data transmissions, e.g., CG transmissions, in inactive state when transmission circumstances may change, such as when the best beam, e.g., SSB, may change. The network node 110 may thereby be enabled to use resources in the wireless communications network 100 more efficiently.

Action 306

In this Action 306, the wireless device 130 sets the unselected remaining resources of the set as inactive. The unselected remaining resources may be one or more unselected transmission occasions, and/or one or more unselected beams. To set resources as inactive may be understood to mean that the resources may still be configured but not used. That is, the wireless device 130 may not use the inactive or inactivated resources for transmission and therefore the network node 110 may be understood to not have to perform blind decoding on these resources. Later, the configuration, e.g., CG-SDT configuration, on these resources, e.g., a beam, may be activated and used.

In some embodiments, the setting 306 of the remaining resources set as inactive, may be based on the received first indication. For example, in these embodiments, the first indication may be received after Action 305 and before Action 306.

When the transmission is done, in accordance to e.g., Action 305, on the selected CG resources, the wireless device 130, in accordance with this Action 306, may need to set any other CG resource, associated with other SSBs, inactive for this UL carrier and release those CG resources.

UL skipping may be used for this to inactivate an unused CG configuration. In case several associations may be configured within a CG configuration, unused transmission occasions within a CG configuration may be inactivated, even if UL skipping is not applied for the selected and used beam. There may be several beams above a threshold, in one option the CG resources for these beams may all be used. As above, the CG resources associated with beams below the threshold may be unused and inactivated.

By setting the unselected remaining resources of the set as inactive in this Action 306, the wireless device 130 may enable the network node to avoid having to monitor UL transmissions from the wireless device, e.g., CG-SDT, in the whole set of resources configured to be for transmission occasions by the wireless device, e.g., all configured beams, which may be understood to be processing demanding. For example, the network node may then be enabled to refrain from having to perform blind decoding on these resources.

Action 307

For DL transmission, the wireless device 130 may monitor the DL beam corresponding to the Receive (RX) beam used when selecting the suitable SSB.

In this Action 307, the wireless device 130 may receive a third indication from the network node 110. The third indication may indicate to release the unselected remaining resources set as inactive. For example, in accordance with this Action 307, a CG resource may also be inactivated due to explicit release DL command, or to an implicit DL command, or implicitly, e.g., skipped n occasions, TA timer etc. To release resources may be understood to mean that the configuration may be understood to be flushed, that is, signaling to configure them again may be understood to be required if they are to be used later.

As a second group of examples, the wireless device 130 may be configured with a CG- SDT configuration related to the beam the wireless device 130 may be located into while in CONNECTED mode, and the network node 110 may, in accordance to e.g., Action 405 described later, activate and reserve the CG-SDT configurations mapped to the beams adjacent to the one selected by the wireless device 130. In this case, when the wireless device 130 is INACTIVE and one of the adjacent beams has a higher RSRP than the one the wireless device 130 may be currently using, the wireless device 130 may simply start transmitting in the new beam. The network node 110 may infer, in accordance to e.g., Action 405 described later, that the wireless device 130 has moved and may update, in accordance with this Action 307, the active CG configurations, through a DL message, by removing the ones mapped to beams that may no longer adjacent be to the new beam, add new configurations for the beams that may now be adjacent, and it may update the TA. This may be required that the network node 110 monitor CG-SDT in all configured beams, which may be processing demanding, and the alternative may be that the network node 110 only monitors one beam and that the wireless device 130 may be required to, in accordance to e.g., Action 304, and Action 404, indicate the beam change in this beam as outlined above. By, in this Action 307, receiving the third indication to release the unselected remaining resources set as inactive in Action 306, the wireless device 130 may then be enabled to release, on command, the inactive resources, thereby enabling that the network node 110 may assign the released resources to the one or more other wireless devices 140. The network node 110 may thereby be enabled to use resources in the wireless communications network 100 more efficiently. The spectral efficiency and resource utilization improvement that may be obtained may be understood to be due to the fact that the wireless device 130 may be understood to be unable to use the resources, e.g., CG-SDT resources on different SSBs, simultaneously. Releasing nonused resources may be understood to mean that they may be used for other wireless devices and may therefore be not wasted. By the wireless device 130 receiving the third indication from the network node 110, the wireless device 130 may only be required to release the resources when the network node 110, which may be aware of the load of the cell 120, may be know it may need the resources to assign them to the one or more other wireless devices 140.

Action 308

In this Action 308, the wireless device 130 may release the unselected remaining resources set as inactive.

The releasing 308 of the remaining resources set as inactive, may be based on the sent second indication. This may be because, for example, the network node 110 may request that the wireless device 130 release the remaining resources, which have not been indicated to have been selected by the wireless device 130.

The releasing in action 308 may be based on the received third indication

If the active/used CG configuration is inactivated, in accordance to e.g., Action 306 and/or Action 307, based on the above, e.g., SS-RSRP drops below a threshold, the wireless device 130 may, in accordance with Action 308, release the CG configuration and need to perform RACH after it may have been released to indicate a new best beam. As a result, it may potentially receive a new CG configuration.

By releasing the unselected remaining resources set as inactive in this Action 308, the wireless device 130 may then enable that the network node 110 may assign the released resources to the one or more other wireless devices 140. The network node 110 may thereby be enabled to use resources in the wireless communications network 100 more efficiently.

In an alternative configuration, the CG-SDT configuration may contain several beam configurations, that is, associated to different SSBs, where one currently best beam may be indicated as ‘active’ and all other beams as inactivated. In this case, the resources may still be kept, even if they are not used by the wireless device 130, even if the wireless device 130 may have been configured to release the CG resources after a number of skipped transmissions. Action 309

In this Action 309, the wireless device 130 may send a fourth indication to the network node 110. The fourth indication may indicate that the one or more selected first resources are to be changed. This may be because, for example, the wireless device 130 may have detected, e.g., by performing measurements, that another beam, which may be understood to correspond, to another transmission occasion, is stronger than the one currently used.

The wireless device 130 may measure the SSBs, and if some condition is triggered, e.g., another SSB RSRP is higher than the currently selected SSB, the wireless device 130 may send, in accordance with this Action 309, an indication of this using the next CG transmission occasion. The indication may e.g., be a configuration index of the new strongest beam as experienced by the wireless device 130.

If, after the first transmissions on the selected CG resources, a reporting criteria is triggered, the wireless device 130 may, in accordance with this Action 309, send the fourth indication to inform the network node 110 of this. The trigger condition may be if SS-RSRP of the selected CG resource drops below a threshold or if the SS-RSRP of another SSB becomes better than the SS-RSRP of the SSB of the selected RSRP resource.

The fourth indication may be in the form of a new Medium Access Control (MAC) Control Element (CE) or encoded in other ways in a MAC Protocol Data Unit (PDU).

The fourth indication may be transmitted on the currently selected CG resource, before it may be inactivated.

The sending in this Action 309 may be performed, e.g., via the first link 141.

In one option, the wireless device 130 may beamform this transmission in the direction of the old SSB, in another option, the wireless device 130 may beamform this transmission in the direction of the new strongest SSB.

In one option, the wireless device 130 may have been configured with contention free RA resources for this purpose so that the new best SSB may be indicated, in accordance to e.g., Action 309, only by a preamble transmission.

By sending the fourth indication in this Action 309, the wireless device 130 may then enable that the network node 110 may know which beam to listen to, in order to receive feature transmissions from the wireless device 130, thereby allowing the network node 110 to be informed of any changes implemented by the wireless device 130, so that the transmission of data by the wireless device 130 may be correctly and efficiently received by the network node 110.

Action 310

In this Action 310, the wireless device 130 may obtain a fifth indication from the network node 110. The fifth indication may indicate a change from the one or more selected first resources to one or more third resources of the set. The obtaining of the fifth indication may be based on the sent fourth indication.

Obtaining in this Action 310 may comprise, retrieving or fetching from a memory, and/or receiving, e.g., from the network node 110, e.g., via the first link 141.

In one option, the wireless device 130 may have been configured with contention free RA resources for this purpose so that the new best SSB may be indicated, in accordance to e.g., Action 309, only by a preamble transmission. With this option, the network node 110 may not need to respond with a Random Access Response message containing an UL grant. Instead, the network node 110 may respond, in accordance with this Action 310, with an updated TA and a new CG configuration. The response may be addressed to the C-RNTI, that the wireless device 130 may have had when it was in connected, or to a new RNTI.

After receiving indication of new best beam, the network node 110 may reconfigure, in accordance with this Action 310, the wireless device 130 with a new CG configuration with an SSB association that may correspond to the new best SSB. This reconfiguration may only alter the previous configuration, e.g., new time offset and SSB association. The DL message with the new configuration may also include a new TA, since the wireless device 130 may be assumed to have moved. The DL message may serve as an acknowledgement of the indication sent from the wireless device 130 of new best SSB.

In one example, the beam re-configuration may consist of the beam index of the beam which the wireless device 130 may need to, from now on, consider as the ‘active’ beam, and change the old beam to ‘inactivated’. If the wireless device 130 has reported a new strongest beam index, as exemplified above, the network node 110 may simply respond, in accordance with this Action 310, with the same beam index for re-configuration. In other cases, the network node 110 may base the beam change on other measurements or input and the beam re-configuration may not be preceded by a beam report from the wireless device 130. The network node 110 may indicate, in the DL message, an index to one of the configured, and then inactivated, CG resources as indicated in the last RRCRelease message, or it may provide a new CG configuration. In the latter case, the wireless device 130 may consider as obsolete all or some of the previous configurations delivered in RRCRelease message.

By obtaining the fifth indication in this Action 310, the wireless device 130 may be enabled to either get a confirmation from the network node 110 that the network node 110 may know which beam to listen to, or it may receive a command to use a group of resources, e.g., a beam, the network node 110 may consider more suitable for the wireless device 130 to perform its UL transmissions, e.g., due to one or more measurements performed by the network node 110, such as interference measurements, which may render a group of resources other than those selected by the wireless device 130 as more suitable for the wireless device 130 to use for UL transmission of the data in inactive state. Action 311

In this Action 311 , the wireless device 130 may select the one or more third resources of the set to transmit further data, based on the obtained fifth indication.

Embodiments of a method, performed by the network node 110, will now be described with reference to the flowchart depicted in Figure 4. The method may be understood to be for handling transmission of data from the wireless device 130. The network node 110 and the wireless device 139 operate in the wireless communications network 100.

The method may be understood to be a computer-implemented method.

In some examples, data may be “Small Data”.

The method may comprise one or more of the following actions.

The method may comprise some of the following actions. In some embodiments, all the actions may be performed. One or more embodiments may be combined, where applicable. Components from one embodiment may be tacitly assumed to be present in another embodiment and it will be obvious to a person skilled in the art how those components may be used in the other exemplary embodiments. All possible combinations are not described to simplify the description. A non-limiting example of the method performed by the network node 110 is depicted in Figure 4. In Figure 4, optional actions are represented with dashed lines. The actions may be performed in a different order than that depicted in Figure 4.

The detailed description of some of the following corresponds to the same references provided above, in relation to the actions described for the wireless device 130 and will thus not be repeated here to simplify the description. For example, the one or more first resources may be one or more transmission occasions, which may correspond to one or more beams, and/or one or more reference signals.

Action 401

In this Action 401, the network node 110 may send the configuration configuring the set of resources to be for transmission occasions by the wireless device 130.

The sending of the configuration may be to the wireless device 130.

In some examples, one of the following may apply: a) the configuration may specify that each of the plurality of transmission occasions corresponds to the respective beam or reference signal, and b) the correspondence between each of the plurality of transmission occasions to the respective beam or reference signal may be specified by the respective configuration. The configuration may comprise the respective configurations for all transmission occasions.

The configuration may be sent to the wireless device 130, in at least one of: i) the first message releasing the connection between the network node 110 and the wireless device 130, and ii) the second dedicated message.

The sending in this Action 401 may be performed, e.g., via the first link 141.

As described earlier, in the first group of examples, in accordance to e.g., Action 301 , and this Action 401 , the set of configured resources may be configured for the wireless device 130 where different CG transmission occasions may have different SSB associations. The configuration may be given in the RRCRelease message sent to the wireless device 130 while in connected state to put the wireless device 130 into Inactive state, or alternatively in another dedicated RRC message, for example while the wireless device 130 may be in RRC_CONNECTED.

Action 402

In this Action 402, the network node 110 may send the first indication to the wireless device 130. The first indication may indicate to inactivate second resources of the set.

The sending in this Action 403 may be performed, e.g., via the first link 141.

In accordance with this Action 402, a CG resource may be inactivated due to explicit release DL command, or implicit DL command, e.g., skipped n occasions, TA timer etc.

Action 403

In this Action 403, the network node 110 receives data, e.g., the first data, from the wireless device 130 during the inactive state of the wireless device 130, on the one or more first resources. The inactive state may be, e.g., as defined in 5G or in a younger system having equivalent functionality.

The receiving in this Action 403 may be performed on the one or more first resources. The first data may be user plane data.

The receiving in this Action 403 may be performed with the proviso that the size of the buffer of the wireless device 130 is smaller than a threshold. The buffer may be the buffer for transmission of the data, which may be referred to herein as a transmit buffer.

The threshold may be the maximum size of the buffer (BSmax), e.g., a maximum transmit buffer size.

The receiving in this Action 403 may be performed, e.g., via the first link 141.

The receiving in this Action 403 of the data may be based on the sent first indication. Action 404

In this Action 404, the network node 110 may receive the second indication from the wireless device 130. The second indication may indicate the selected one or more first resources.

The receiving in this Action 404 may be performed, e.g., via the first link 141.

Action 405

In this Action 405, the network node 110 determines which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device 130, have been one of: i) the one or more first resources selected by the wireless device 130 to send the data, and/or ii) are unused, unselected remaining resources, or iii) set as inactive by the wireless device 130. The set of resources have the correspondence to the plurality of beams or the reference signals, e.g., Synchronization Signal Blocks (SSB), transmitted by the network node 110.

Determining in this Action 405 may comprise e.g., calculating or deriving.

The determining in this Action 405 may be based on the received data 403, that is on the one or more first resources on which the data may have been received in Action 403.

The network node 110 may, in accordance with this Action 405, determine as a result of the use of this CG resource associated with this SSB, what CG configurations may be inactivated by the wireless device 130, and therefore available to other users. The RX beam of the network node 110 may be used to receive UL transmission, and thus the network node 110 may infer which SSB may be selected by the wireless device 130, or the network node 110 may perform the determining in this Action 405 by using the configured CG transmission occasion to the SSB mapping.

By the network node 110 determining which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device 130, have been selected to send the data by the wireless device 130, the network node 110 may then be enabled to avoid having to monitor UL transmissions from the wireless device 130, e.g., CG-SDT, in the whole set of resources configured to be for transmission occasions by the wireless device 130, e.g., all configured beams, which may be understood to be processing demanding.

By the network node 110 determining which one or more resources, of the set of resources configured to be for transmission occasions by the wireless device 130, have been unused, unselected remaining resources, or set as inactive by the wireless device, the network node may be able to know which resources may be available to be assigned to the one or more other wireless devices 140. Hence, the network node 110 may thereby be enabled to use resources in the wireless communications network 100 more efficiently, increasing the capacity of the wireless communications network 100, as well as decreasing its latency. Action 406

In this Action 406, the network node 110 may send the third indication to the wireless device 130. The third indication may indicate to release the unselected remaining resources, e.g., set as inactive. For example, a CG resource may also be inactivated due to explicit release command DL, in accordance with this Action 406, or an implicit DL command, e.g., skipped n occasions, TA timer etc.

The sending in this Action 406 may be based on a result of the determination.

The sending in this Action 406 of the third indication may be based on the received second indication.

The sending in this Action 406 may be, e.g., via the first link 141.

As explained later, in a second group of examples, the wireless device 130 may be configured with a CG-SDT configuration related to the beam the wireless device 130 may be located into while in CONNECTED mode, and the network node 110 may, in accordance to e.g., Action 405, activate and reserve the CG-SDT configurations mapped to the beams adjacent to the one selected by the wireless device 130. In this case, when the wireless device 130 is INACTIVE and one of the adjacent beams has a higher RSRP than the one the wireless device 130 may be currently using, the wireless device 130 may simply start transmitting in the new beam. The network node 110 may infer, in accordance to e.g., Action

405, that the wireless device 130 has moved and may update, in accordance with this Action

406, the active CG configurations, through a DL message, by removing the ones mapped to beams that may no longer adjacent be to the new beam, add new configurations for the beams that may now be adjacent, and it may update the TA. This may be required that the network node 110 monitor CG-SDT in all configured beams, which may be processing demanding, and the alternative may be that the network node 110 only monitors one beam and that the wireless device 130 may be required to, in accordance to e.g., Action 304, and Action 404, indicate the beam change in this beam as outlined above.

Action 407

In this Action 407, the network node 110 may assign the unselected remaining resources to one or more other wireless devices 140.

Assigning may be understood as e.g., allocating.

Action 408

In this Action 408, the network node 110 may receive the fourth indication from the wireless device 130. The fourth indication may indicate that the one or more selected first resources are to be changed. The receiving in this Action 408 may be performed, e.g., via the first link 141.

As explained earlier, the wireless device 130 may measure the SSBs, and if some condition is triggered, e.g., another SSB RSRP is higher than the currently selected SSB, the wireless device 130 may send, in accordance with this Action 408, an indication of this using the next CG transmission occasion. The indication may e.g., be a configuration index of the new strongest beam as experienced by the wireless device 130.

Action 409

In this Action 409, the network node 110 may send the fifth indication to the wireless device 130. The fifth indication may indicate the change from the one or more selected first resources to the one or more third resources of the set.

The sending of the fifth indication may be to the wireless device 130.

The sending in this Action 409 may be performed, e.g., via the first link 141.

As described earlier, in one example, the beam re-configuration may consist of the beam index of the beam which the wireless device 130 may need to, from now on, consider as the ‘active’ beam, and change the old beam to ‘inactivated’. If the UE has reported a new strongest beam index, as exemplified above, the network node 110 may simply respond, in accordance with this Action 409, with the same beam index for re-configuration. In other cases, the network node 110 may base the beam change on other measurements or input and the beam re-configuration may not be preceded by a beam report from the wireless device 130. The network node 110 may indicate, in the DL message, an index to one of the configured, and then inactivated, CG resources as indicated in the last RRCRelease message, or it may provide a new CG configuration. In the latter case, the wireless device 130 may consider as obsolete all or some of the previous configurations delivered in RRCRelease message.

In one option, the wireless device 130 may have been configured with contention free RA resources for this purpose so that the new best SSB may be indicated, in accordance to e.g., Action 309 and Action 408, only by a preamble transmission. With this option, the network node 110 may not need to respond with a Random Access Response message containing an UL grant. Instead, the network node 110 may respond, in accordance to e.g., Action 409, and Action 310, with an updated TA and a new CG configuration. The response may be addressed to the C-RNTI, that the wireless device 130 may have had when it was in connected, or to a new RNTI.

After receiving indication of new best beam, in accordance to e.g., Action 408, the network node 110 may reconfigure, in accordance to e.g., Action 409 and Action 310, the wireless device 130 with a new CG configuration with an SSB association that may correspond to the new best SSB. This reconfiguration may only alter the previous configuration, e.g., new time offset and SSB association. The DL message with the new configuration may also include a new TA, since the wireless device 130 may be assumed to have moved. The DL message may serve as an acknowledgement of the indication sent from the wireless device 130 of new best SSB.

Figure 5 is a schematic diagram illustrating two options of configuring CG resources, according to embodiments herein. In option 1 , four different CG configurations, Config#1 , Config#2, Config#3, and Config#4, are configured for the wireless device 130 where all CG transmission occasions in a configuration correspond to an association with one beam, SSB1- SSB4. That is, each configuration may correspond to a specific SSB association. In the second option in Figure 5, one CG configuration, represented in the figure as “Same config”, may contain different associations between CG transmission occasions and beams, SSB1- SSB4. That is, different transmission opportunities may correspond to different SSB associations. In an alternative example, multiple CG transmission configurations may be configured per one associated SSB or beam.

Embodiments herein, may be understood to enable to reduce the resources that may be needed to perform transmissions of data by the wireless device 130, e.g., CG transmissions, in Inactive state, for example, when the best SSB may change.

Figure 10: Telecommunication network connected via an intermediate network to a host computer in accordance with some embodiments

With reference to Figure 10, in accordance with an embodiment, a communication system includes telecommunication network 1010 such as the wireless communications network 100, for example, a 3GPP-type cellular network, which comprises access network 1011 , such as a radio access network, and core network 1014. Access network 1011 comprises a plurality of network nodes such as the network node 110. For example, base stations 1012a, 1012b, 1012c, such as NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 1013a, 1013b, 1013c. Each base station 1012a, 1012b, 1012c is connectable to core network 1014 over a wired or wireless connection 1015. A plurality of user equipments, such as the wireless device 130 are comprised in the wireless communications network 100. In Figure 10, a first UE 1091 located in coverage area 1013c is configured to wirelessly connect to, or be paged by, the corresponding base station 1012c. A second UE 1092 in coverage area 1013a is wirelessly connectable to the corresponding base station 1012a. While a plurality of UEs 1091 , 1092 are illustrated in this example, the disclosed embodiments are equally applicable to a situation where a sole UE is in the coverage area or where a sole UE is connecting to the corresponding base station 1012. Any of the UEs 1091 , 1092 are examples of the wireless device 130.

Telecommunication network 1010 is itself connected to host computer 1030, which may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server or as processing resources in a server farm. Host computer 1030 may be under the ownership or control of a service provider, or may be operated by the service provider or on behalf of the service provider. Connections 1021 and 1022 between telecommunication network 1010 and host computer 1030 may extend directly from core network 1014 to host computer 1030 or may go via an optional intermediate network 1020. Intermediate network 1020 may be one of, or a combination of more than one of, a public, private or hosted network; intermediate network 1020, if any, may be a backbone network or the Internet; in particular, intermediate network 1020 may comprise two or more sub-networks (not shown).

The communication system of Figure 10 as a whole enables connectivity between the connected UEs 1091 , 1092 and host computer 1030. The connectivity may be described as an over-the-top (OTT) connection 1050. Host computer 1030 and the connected UEs 1091 , 1092 are configured to communicate data and/or signaling via OTT connection 1050, using access network 1011 , core network 1014, any intermediate network 1020 and possible further infrastructure (not shown) as intermediaries. OTT connection 1050 may be transparent in the sense that the participating communication devices through which OTT connection 1050 passes are unaware of routing of uplink and downlink communications. For example, base station 1012 may not or need not be informed about the past routing of an incoming downlink communication with data originating from host computer 1030 to be forwarded (e.g., handed over) to a connected UE 1091.

Communication interface 1126 may be configured to facilitate connection 1160 to host computer 1110. Connection 1160 may be direct, or it may pass through a core network (not shown in Figure 11) of the telecommunication system and/or through one or more intermediate networks outside the telecommunication system. In the embodiment shown, hardware 1125 of base station 1120 further includes processing circuitry 1128, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions.

It is noted that host computer 1110, base station 1120 and UE 1130 illustrated in Figure 11 may be similar or identical to host computer 1030, one of base stations 1012a, 1012b, 1012c and one of UEs 1091 , 1092 of Figure 10, respectively. This is to say, the inner workings of these entities may be as shown in Figure 11 and independently, the surrounding network topology may be that of Figure 10.

In Figure 11 , OTT connection 1150 has been drawn abstractly to illustrate the communication between host computer 1110 and UE 1130 via base station 1120, without explicit reference to any intermediary devices and the precise routing of messages via these devices. Network infrastructure may determine the routing, which it may be configured to hide from UE 1130 or from the service provider operating host computer 1110, or both. While OTT connection 1150 is active, the network infrastructure may further take decisions by which it dynamically changes the routing (e.g., on the basis of load balancing consideration or reconfiguration of the network).

Wireless connection 1170 between UE 1130 and base station 1120 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments improve the performance of OTT services provided to UE 1130 using OTT connection 1150, in which wireless connection 1170 forms the last segment. More precisely, the teachings of these embodiments may improve the latency, signalling overhead, and service interruption and thereby provide benefits such as reduced user waiting time, better responsiveness and extended battery lifetime.

A measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring OTT connection 1150 between host computer 1110 and UE 1130, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring OTT connection 1150 may be implemented in software 1111 and hardware 1115 of host computer 1110 or in software 1131 and hardware 1135 of UE 1130, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which OTT connection 1150 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which software 1111 , 1131 may compute or estimate the monitored quantities. The reconfiguring of OTT connection 1150 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect base station 1120, and it may be unknown or imperceptible to base station 1120. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating host computer 1110’s measurements of throughput, propagation times, latency and the like. The measurements may be implemented in that software 1111 and 1131 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using OTT connection 1150 while it monitors propagation times, errors etc. The wireless device 130 embodiments relate to Figure 3, Figure 5, Figure 6 and Figures 10-15.
