Description

Wireless device, network node and method for processing data transmission
Technical Field
The present invention relates generally to wireless devices and methods performed thereby for handling transmission of data to a network node. The present disclosure also relates generally to a network node, and a method performed thereby for handling transmission of data from a wireless device.
Background
A wireless device within a wireless communication network may be, for example, a User Equipment (UE), a Station (STA), a mobile terminal, a wireless terminal, a terminal, and/or a Mobile Station (MS). Wireless devices are capable of wireless communication in a cellular communication network or wireless communication network (sometimes also referred to as a cellular radio system, cellular system, or cellular network). The communication may be performed, for example, between two wireless devices, between a wireless device and a conventional telephone, and/or between a wireless device and a server via a Radio Access Network (RAN) and one or more core networks that may be included in the wireless communication network. A wireless device may also be referred to as a mobile phone, cellular phone, laptop, or tablet with wireless capability, to mention a few further examples. A wireless device in this context may be, for example, a portable, pocket-storable, handheld, computer-containing, or vehicle-mounted mobile device capable of voice and/or data communication with another entity (e.g., another terminal or server) via the RAN.
The wireless communication network covers a geographical area which may be divided into cell areas, with each cell area being served by a network node, which may be an access node, such as a radio network node, radio node or base station, e.g. a Radio Base Station (RBS), which may sometimes be referred to as e.g. a gNB, evolved node B ("eNB"), eNodeB, "NodeB", "B node", transmission Point (TP) or BTS (base transceiver station), depending on the technology and terminology used. Based on the transmission power and thus the cell size, the base stations may be of different categories, such as wide area base stations, medium range base stations, local area base stations, home base stations, pico base stations, etc. A cell is a geographical area where radio coverage is provided by a base station or a radio node at a base station site or a radio node site, respectively. A base station located at a base station site may serve one or several cells. In addition, each base station may support one or several communication technologies. The base station communicates with terminals within range of the base station over an air interface operating at radio frequencies. The wireless communication network may also be a non-cellular system including network nodes that may utilize a serving beam to serve a receiving node, such as a wireless device. In third generation partnership project (3 GPP) Long Term Evolution (LTE), a base station, which may be referred to as an eNodeB or even an eNB, may be directly connected to one or more core networks. In the context of the present 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 transmission paths in the opposite direction, i.e. from the wireless device to the base station.
The standardization organization 3GPP is currently specifying a new radio interface called NR or 5G-UTRA, and a fifth generation (5G) packet core network, which may be referred to as a Next Generation (NG) core network, abbreviated NG-CN, NGC or 5G CN.
Internet of things (IoT)
The internet of things (IoT) may be understood as an interconnected network of communication devices, such as physical devices, vehicles (which may also be referred to as "connection devices" and "smart devices"), buildings, and other items, embedded with electronic devices, software, sensors, actuators, and network connections, that may enable these objects to collect and exchange data. IoT may allow objects to be sensed and/or controlled remotely over existing network infrastructure.
"thing" in the sense of IoT may refer to a wide variety of devices such as heart monitoring implants, biochip transponders on farm animals, motorized clamps along the sea water, 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 lighting, control and automation of heating, e.g. "smart" thermostats, ventilation, air conditioning, and appliances that may be remotely monitored using telecommunications, such as washing machines, dryers, ovens, refrigerators or freezers. These devices can collect data with the aid of various prior art techniques and then automatically transfer the data between other devices.
It is expected that in the near future the number of IoT devices will be very large. There are various predictions where one prediction assumes that there will be >60000 devices per square kilometer and another prediction assumes that there will be 1000000 devices per square kilometer. Most of these devices are intended to be stationary, such as gas and electricity meters, vending machines, and the like.
Machine Type Communication (MTC)
In recent years, machine Type Communication (MTC), especially in the context of internet of things (IoT), has been shown to be an increasing part of cellular technology. MTC devices may be communication devices, typically wireless communication devices or simple user devices, which are self-controlling and/or automatically controlled unattended machines and are typically not associated with an activated human user to generate data traffic. MTC devices are generally simpler than traditional mobile phones or smart phones and are generally associated with more specific applications or purposes. MTC involves communications to and/or from MTC devices in a wireless communication network, which typically have quite different properties and other requirements than those associated with, for example, conventional mobile phones and smartphones. In the context and development of IoT, it is apparent that MTC traffic will increase and thus need to be increasingly supported in wireless communication systems.
Small data transmission
The NR supports a Radio Resource Control (RRC) _inactive state and the network may generally maintain UEs with infrequent (e.g., periodic and/or aperiodic) data transmissions in the rrc_inactive state. The rrc_inactive state does not support data transfer until Rel-16. Thus, the UE must resume the connection, i.e., move to the rrc_connected state for any DL (i.e., mobile Terminated (MT) data) and UL (i.e., mobile Originated (MO) data). No matter how small and infrequent data packets, connection establishment and subsequent release to the INACTIVE state may occur for each data transmission. This results in unnecessary power consumption and signaling overhead.
Specific examples of small and infrequent data traffic may include the following use cases. For smart phone applications: traffic from Instant Messaging (IM) services, such as WhatsApp, QQ, wechat, etc., heartbeat/keep-alive traffic from IM/email clients and other applications, push notifications from various applications. For non-smart phone applications: traffic from wearable devices, such as periodic location information, etc., from sensors, such as industrial wireless sensor networks that transmit temperature, pressure readings, etc., periodically or in an event-triggered manner, smart meters and smart meter networks that transmit periodic meter readings.
As described in 3GPP TS22.891v14.2.0, an NR system may be required: efficient and flexible for low throughput short data bursts, support efficient signaling mechanisms, e.g., signaling may be less than payload, and generally reduce signaling overhead.
Signaling overhead for small data packets from an INACTIVE state UE is a general problem and as more UEs in the NR appear, it will become a critical issue not only for network performance and efficiency, but also for UE battery performance. In general, any device with intermittent small data packets in an INACTIVE state may benefit from enabling small data transmissions in the INACTIVE state.
Key enabling factors for small data transmissions in NR, namely the INACTIVE state, 2-step, 4-step Random Access Channel (RACH) and configured grant type-1 have been designated as part of Rel-15 and Rel-16.
NR frame structure
Similar to LTE, NR may use Orthogonal Frequency Division Multiplexing (OFDM) in the downlink, i.e. from a network node, gNB, eNB or base station to a user equipment or UE. The basic NR physical resources on the antenna ports can thus be seen as a time-frequency grid as shown in fig. 1, where Resource Blocks (RBs) in a 14 symbol slot are shown. A resource block may be understood to correspond to 12 consecutive subcarriers in the frequency domain. The resource blocks may be numbered in the frequency domain starting from 0 at one end of the system bandwidth. Each resource element may be understood to correspond to one OFDM subcarrier during one OFDM symbol interval.
NR may support different subcarrier spacing values. The supported subcarrier spacing values, also referred to as different values, may be given by Δf= (15 x 2 μ (kHz), where μ e (0, 1,2,3, 4) Δf=15 kHz may be understood as 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 subframes of equal size, each subframe being 1 millisecond, similar to LTE. The subframe may be further divided into a plurality of equal duration slots. The slot length of the subcarrier spacing Δf= (15 x 2 μ) kHz may be 1/2 μmilliseconds. For Δf=15 kHz, there may be only one slot per subframe, and a slot may consist of 14 OFDM symbols.
Downlink transmissions may be dynamically scheduled, i.e., in each time slot, the gNB may transmit Downlink Control Information (DCI) regarding which UEs may have to be transmitted with data and which resource blocks in the current downlink time slot may have to be transmitted with data. The control information may typically be transmitted in the previous or two OFDM symbols of each slot in the NR. The control information may be carried on a physical control channel (PDCCH) and the data may be carried on a Physical Downlink Shared Channel (PDSCH). The UE may first detect and decode the PDCCH and if the PDCCH is successfully decoded, it may decode the corresponding PDSCH based on the downlink allocation provided by the control information decoded in the PDCCH.
In addition to the PDCCH and PDSCH, other channels and reference signals may be transmitted in the downlink, including synchronization signals and PBCH blocks (SSBs), channel state information reference signals (CSI-RS), and the like.
Uplink data transmissions carried on a Physical Uplink Shared Channel (PUSCH) may also be dynamically scheduled by the gNB by transmitting DCI. The DCI that may be transmitted in the DL region may always indicate a scheduling time offset so that PUSCH may be transmitted in a slot in the UL region.
Beamforming is expected to be widely used for NR operation, at least in the millimeter wave range for transmission and reception. For UL transmissions, the UE and the gNB may need to establish and understand a spatial relationship before transmission in the UL can take place. A spatial relationship may be defined between UL channel/reference signals such as PUSCH, PUCCH, and Sounding Reference Signals (SRS) and DL reference signals such as CSI-RS, SS/PBCH blocks, or another UL reference signal such as SRS. If UL channel/signal a is spatially correlated with reference signal B, it can be understood to mean that the UE may need to beamform a in the same way as it receives/transmits B, that is, by using the same spatial filter for a as it can use to receive B. By establishing a spatial relationship, the UE may know in which direction to beamform its transmit signal toward the target gNB, and the gNB may also know how to tune its Receiver (RX) beam toward the beam or signal transmitted by the UE.
The Primary Synchronization Signal (PSS) and the Secondary Synchronization Signal (SSS) and the Physical Broadcast Channel (PBCH) may be transmitted in the synchronization signal and the PBCH block (SSB). SSB transmission periods may be configured, but SSBs may also have different time positions within a field in a subframe in which they may be transmitted-SSBs having different time positions within a field may be transmitted in different spatial directions using different beams. See, for example, section 5.2.4 of TS 38.300v16.3.0 and section 4.1 of TS 38.212 v16.3.0.
NR small data transmission in INACTIVE state
New Work Item (WI) RP-200954 "new work item on NR small data transmission in INACTIVE state" has been approved in 3GPP, with the focus of optimizing the transmission of small data payloads by reducing signaling overhead. WI contains the following objectives. The work item can be understood as enabling small data transfer in rrc_inactive state as follows. For UL small data transmissions in rrc_inactive state and Random Access Channel (RACH) based schemes, i.e. 2-step and 4-step RACH, the WI may first enable a general procedure to enable User Plane (UP) data transmission of small data packets from the INACTIVE state, e.g. using MSGA or MSG3, [ RAN2]. Second, WI may enable a flexible payload size larger than the Rel-16 Common Control Channel (CCCH) message size, which is currently possible for the INACTIVE state of MSGA and MSG 3. In order to support UL UP data transmission, the actual payload size may depend on the network configuration, [ RAN2]. Third, for RACH based solutions [ RAN2, RAN3], WI may enable context acquisition and data forwarding in the inactive state, with and without anchor relocation. Incidentally, the security of the above solution may need to be checked by SA 3. For rrc_inactive state and UL data transmission on preconfigured Physical Uplink Shared Channel (PUSCH) resources, the WI may implement reuse configured grant type 1 when Time Alignment (TA) may be active. First, WI may enable a generic procedure for small data transfers from INACTIVE state RAN2 over configured license type 1 resources. Second, the WI may enable configuration of the configured grant type 1 resources for small data transmission, in UL for INACTIVE state [ RAN2].
Similar signaling optimizations for small data have been introduced for narrowband IoT (NB-IoT) and LTE-M through Rel-15 Early Data Transmission (EDT) and Rel-16 pre-configured uplink resources (PUR). Some similar solutions may be expected for NR, except that Rel-17 NR small data only supports RRC INACTIVE states, small data based on 2-step RACH may also be included, and may also be required to include conventional complexity mobile broadband (MBB) UEs. Both can be understood as supporting only Mobile Originated (MO) traffic.
In the context of Small Data Transfer (SDT), the possibility of transferring subsequent data, i.e. transferring more data segments that do not fit in the Msg3 transport block, has been discussed. Such data segments may be transmitted in rrc_connected, as in the legacy after the 4-step RACH procedure has been completed, or they may be transmitted in rrc_inactive before the UE transitions to rrc_connected. In the former case, the transmission may be more efficient because the gNB and UE may be properly configured based on 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 the transmission may also collide with transmissions from other UEs because the contention has not been resolved yet.
The work item has started in 3GPP conference RAN2#111-e and has achieved the following related protocol [1]. As a first protocol, small data transmissions with Radio Resource Control (RRC) messages may be supported as a baseline for Random Access (RA) based and configuration admission (CG) based schemes. As a second protocol, the 2-step RACH or the 4-step RACH may need to be applied to RACH-based uplink small data transmission in rrc_inactive. As a third protocol, uplink small data may be transmitted in MSGA of 2-step RACH or msg3 of 4-step RACH. As a fourth protocol, small data transmissions may be configured by the network on a per Data Radio Bearer (DRB) basis. As a fifth protocol, a data amount threshold may be used for the UE to decide whether to SDT. How the data volume was calculated for further study (FFS). As a sixth protocol, FFS may further use an "additional SDT-specific" Reference Signal Received Power (RSRP) threshold to determine if the UE should SDT. As a seventh protocol, UL/DL transmission following ULSDT may be supported without switching to rrc_connected. As an eighth protocol, multiple UL and DL packets may be sent as part of the same SDT mechanism when the UE is in rrc_inactive without switching to rrc_connected on dedicated grants. Details of FFS may be required and whether there are any network indications.
It should be noted that some of the mechanisms discussed in this document have been agreed upon and thus they are not representative of the purpose of the embodiments herein. They can be understood to provide a complete working solution.
In RAN2#112-e, the following protocol is achieved. First, the configuration of configuration grant resources for UE uplink small data transmission may be contained in the RRCRelease message. FFS, if there are other dedicated messages, can configure CG in INACTIVE CG. Configuration can be understood as a contention resolution procedure with only type 1CG, no CG. Second, the configuration of the configured licensed resources may include a type 1CG configuration. If there are multiple configured CGs, FFS is allowed. Third, it may be necessary to introduce a new Timing Advance (TA) timer for TA maintenance specified for grant-based small data transmissions configured in rrc_inactive. FFS regards the procedure, the validity of the TA, and how to handle TA timer expiration. The TA timer may be configured with the CG configuration in an RRCRelease message. Fourth, the configuration of the configured grant resources for UE small data transmission may be valid only in the same serving cell. FFS is used for other CG validity criteria such as timer, UL/Supplementary UL (SUL) aspects, etc. Fifth, the UE may use configured license-based small data transmissions if at least the following criteria are met: (1) user data is less than a data amount threshold; (2) the configured licensed resources are configured and valid; and (3) the UE has a valid TA. FFS is used for candidate beam criteria. Sixth, from the perspective of RAN2, CG-based SDTs may require an association between CG resources and SSBs. FFS regards how RAN1 configures the association or provides the association to the UE. LS is sent to RAN1 to begin a discussion of how the association is established. One option to mention RAN2 considerations is explicit configuration with RRC release message. Seventh, a synchronization signal reference signal received power (SS-RSRP) threshold may be selectively configured for SSBs. The UE may select one of the SSBs with SS-RSRP above a threshold and select the associated CG resources for UL data transmission.
In the latest discussion, it has been proposed that a UE may configure a CG with multiple associations, i.e. different CG occasions may be associated with different SSBs.
Since Rel-15, two types of Configuration Grant (CG) UL transmission schemes are supported in NR, referred to in the standard as CG type 1 and CG type 2. The main distinction between these two types of CG transmissions is to be understood that for CG type 1, the uplink grant may be provided and automatically activated by RRC configuration, while in the case of CG type 2, the uplink grant may be provided and activated via L1 signaling, i.e. by ul dci with a Cyclic Redundancy Checksum (CRC) scrambled by a configured scheduling radio network temporary identifier (CS-RNTI). In both cases, the spatial relationship for PUSCH transmissions with configuration grants may be indicated by an uplink grant, either configured by Radio Resource Control (RRC) or provided by UL DCI. The uplink grant may contain a SRS-resource indicator field that points to one of the SRS resources in the SRS resource configuration, which in turn may be configured to have a spatial relationship with the DL Reference Signal (RS), SSB, or CSI-RS, or another SRS resource.
In the case where the SRS resource indicator is included in the uplink grant and the RRC SRS resource configuration, it can be considered that the PUSCH having the configuration grant is transmitted using the same precoder or beamforming weight as that used for transmission of the reference SRS.
Configured scheduling
In NR, the configured scheduling may be used to allocate semi-static periodic allocations or grants for UEs. For the uplink, there may be two types of configured scheduling schemes: type 1 and type 2. For type 1, the permission for configuration may be configured only through RRC signaling. For type 2, a configuration procedure similar to the semi-persistent scheduling (SPS) UL in LTE is defined, i.e. some parameters may be preconfigured by RRC signaling and some physical layer parameters may be configured by a Medium Access Control (MAC) scheduling procedure. Details can be found in clause 3GPP TS 38.321v.16.2.1, 5.8.2[1 ].
As with SPS in LTE, CG periodicity may be configured by RRC, which may be specified in ConfiguredGrantConfig IE (information element IE). Depending on the subcarrier spacing (SCS), NR may support different periodicity values. For example, for SCS of 15 and 30kHz, the following periods expressed in a plurality of OFDM symbols may be supported. 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 type 1 configured grants, the time domain allocation of PUSCH may be configured purely by RRC signaling, except for periodicity. The time domain offset may provide a slot offset relative to a subframe number (SFN) 0. The time domain allocation may provide an index to a table of 16 possible combinations of PUSCH mapping types (type a or type B), starting symbols S for mapping (s=ofdm symbols 0, 2,4 or 8 within a slot), and mapping length L (l=4, 6, 8, 10, 12 or 14 OFDM symbols).
Details of the configuration of the RRC specification, 3GPP TS 38.331,v.16.2.0,Rel.16) are shown below. Table 1 shows ConfiguredGrantConfig IE in the RRC specification.
TABLE 1
In a serving cell, a plurality of active configuration grants for a given bandwidth part (BWP) may be provided for the UE. The introduction of multiple configuration permissions may be used at least to enhance reliability and reduce latency for critical services.
Repeated configuration of UL
Repetition of Transport Blocks (TBs) may also be supported in NR and the same resource configuration may be used for K repetitions of TBs including initial transmissions. The parameters repK and repK-RV of the higher layer configuration may define K repetitions to be applied to the transmitted transport block, and redundancy version patterns to be applied to the repetitions. For the nth transmission occasion in K repetitions, n=1, 2, …, K, which may be associated with the (mod (n-1, 4) +1) th value in the configured RV sequence. The initial transmission of a transport block may begin with: a) K repeated first transmission occasions if the configured RV sequence may be {0,2,3,1}, b) K repeated any transmission occasions if the configured RV sequence may be {0,3,0,3}, which may be associated with rv=0, or c) K repeated any transmission occasions if the configured RV sequence is {0, 0}, except for the last transmission occasion when k=8.
For any RV sequence, it may be required to terminate the repetition after transmitting K repetitions, or to terminate the repetition at the last transmission occasion of K repetitions within periodicity P, or to terminate the repetition when UL grants for scheduling the same TB may be received within periodicity P, whichever arrives first. It may not be desirable for the UE to be configured to transmit K repetitions for a duration greater than the duration derived from periodicity P.
For type 1 and type 2PUSCH transmissions with configuration grants, when the UE is configured with repK >1, the UE may be required to repeat the TB over repK consecutive slots, with the same symbol allocation applied in each slot. If the UE procedure for determining the slot configuration defined in sub-clause 11.1 of TS 38.213, v.16.3.0 determines the symbol of the slot allocated to PUSCH as a downlink symbol, the transmission on the slot may be omitted for multi-slot PUSCH transmission.
Despite the advantages, existing small data transmission methods may result in wasted resources or lost communication between the transmitter and the receiver.
Disclosure of Invention
As part of the development of the embodiments herein, one or more challenges of the prior art will first be identified and discussed.
Uplink beam misalignment between the gNB and the 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 for the timing and beam direction of the transmission or grant. The gNB with analog beamforming capability can only listen to UL transmissions in one direction per antenna panel at a time.
For SDT, the UE may be configured with CG of SDT in inactive state, which may be spatially correlated with SSB. However, if the UE moves such that the current SSB RSRP is no longer sufficient to meet acceptable transmission performance, there is currently no solution to deal with this except to stop using CG configuration. Another alternative may be to use a CG configuration for the SDT in inactivity, which may be spatially related to several SSBs, i.e. different CG transmission occasions may be associated with different SSBs, and the UE may select the transmission occasion corresponding to the best SSB (i.e. the SSB that may have the highest RSRP). However, such an alternative may incur a significant overhead since the UE may use only one of the spatial associations, which means that no other CG transmission occasions will be used when the UE is stationary.
It is an object of embodiments herein to improve the handling of transmissions 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 communication network. During an inactive state of the wireless device, the wireless device transmits data to the network node. The wireless device transmits data on one or more first resources. The one or more first resources are selected from a set of resources configured for transmission occasions by the wireless device. The set of resources has correspondence with a plurality of beams or reference signals transmitted by the network node. The wireless device then sets the remaining unselected resources of the group to 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 processing a transmission of data from a wireless device. The network node operates in a wireless communication network. The network node receives data from the wireless device during an inactive state of the wireless device. The network node receives data on one or more first resources. The network node then determines which one or more of the set of resources configured for transmission occasions by the wireless device is one of: i) One or more first resources selected by the wireless device to transmit data, ii) unused, unselected remaining resources, and iii) set inactive by the wireless device. The set of resources has correspondence with a plurality of beams or reference signals transmitted by the network node.
According to a third aspect of embodiments herein, the object is achieved by a wireless device for handling transmission of data to a network node. The wireless device is configured to operate in a wireless communication network. The wireless device is further configured to transmit data to the network node during an inactive state of the wireless device. The wireless device is configured to transmit data on one or more first resources. The one or more first resources are configured to be selected from the set of resources configured to be used by the wireless device for transmission occasions. The set of resources is configured to have correspondence to a plurality of beams or reference signals configured to be transmitted by the network node. The wireless device is further configured to set the remaining unselected resources of the group to inactive.
According to a fourth aspect of embodiments herein, the object is achieved by a network node for handling transmission of data from a wireless device. The network node is configured to operate in a wireless communication network. The network node is further configured to receive data from the wireless device on one or more first resources during an inactive state of the wireless device. The network node is configured to determine which one or more resources of the set of resources that are configured for use by the wireless device for a transmission occasion is one of: i) One or more first resources configured to be selected by the wireless device to transmit data, ii) unused, unselected remaining resources, and iii) set to inactive by the wireless device. The set of resources is configured to have correspondence to a plurality of beams or reference signals configured to be transmitted by the network node.
By sending data to the network node on the selected one or more first resources and setting the remaining non-selected resources of the group to inactive, the wireless device may cause the network node to avoid having to monitor UL transmissions, e.g. CG-SDT, from the wireless device in the entire resource group configured for transmission occasions, e.g. all configured beams, by the wireless device, which may be understood as processing requirements. For example, the network node can then avoid having to perform blind decoding on these resources.
Further, by setting the remaining unselected resources of the group to inactive, the wireless device may release the resources. Thus, when the transmission environment may change, such as when the optimal beam (e.g., SSB) may change, the wireless device may reduce the resources that may be needed to perform data transmission (e.g., CG transmission) in an inactive state. Thereby, the network node is able to more efficiently use the resources in the wireless communication network.
Determining by the network node which one or more of a set of resources configured for the wireless device transmission occasion has been selected by the wireless device for transmitting data, and which one or more of a set of resources configured for the wireless device transmission occasion has not been used, the remaining resources that have not been selected, or is set to be inactive by the wireless device, may enable the network node to avoid having to monitor UL transmissions (e.g., CG-SDT) from the wireless device throughout a set of resources (e.g., all configured beams) configured for the transmission occasion by the wireless device, which may be understood as processing requirements.
By the network node determining which resources of the set of resources are unused, the remaining resources are not selected, or are set to be inactive by the wireless device, which resources are available for allocation to one or more wireless devices. Thus, the network node is thereby able to more efficiently use resources in the wireless communication network, increase the capacity of the wireless communication network, and reduce its latency.

Detailed Description
Particular aspects of the present invention and its embodiments may provide solutions to the above or other challenges. Embodiments herein may be generally understood as involving SSB changes for CG SDT operation in an inactive state.
To overcome the high overhead problem of CG configurations with multiple SSB associations, according to embodiments herein, only the association that a UE can use when it first CG transmission can be kept, while other associations can be released. This may be understood to mean that when the UE may make its first transmission on the CG, it may select the CG transmission occasion that may have the best SSB association, i.e. corresponds to the SSB with the highest SSB-RSRP. The selection of the best SSB association and CG transmission occasions may trigger the UE to treat CG transmission occasions corresponding to other SSBs as invalid, and thus they may be deactivated. In the same way, the gNB may allocate these resources to other UEs.
In case the UE subsequently finds that other SSB associations may be better, it may signal the gNB, which may then reconfigure the resources.
Some embodiments are described more fully hereinafter with reference to the accompanying drawings, in which examples are shown. In this section, the embodiments herein will be described in more detail by way of a number of exemplary embodiments. However, other embodiments are included within the scope of the subject matter disclosed herein. The disclosed subject matter should not be construed as limited to 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 present by default in another embodiment, and it will be apparent to one skilled in the art how to use these components in other exemplary embodiments.
Fig. 2 depicts two non-limiting examples of wireless networks or wireless communication networks 100, sometimes also referred to as wireless communication systems, cellular radio systems, or cellular networks, in which embodiments herein may be implemented. The wireless communication network 100 may be a 5G system, a 5G network, or a next generation system or network. In other examples, the wireless communication network 100 may alternatively or additionally support other technologies such as, for example, long Term Evolution (LTE), e.g., LTE-M, LTE Frequency Division Duplexing (FDD), LTE Time Division Duplexing (TDD), LTE half-duplex frequency division duplexing (HD-FDD), LTE operating in unlicensed frequency bands such as LTE LAA, ELAA, feldaa, and/or multewire. In other examples, the wireless communication network 100 may support other technologies such as Wideband Code Division Multiple Access (WCDMA), universal Terrestrial Radio Access (UTRA) TDD, global system for mobile communications (GSM) networks, GSM/enhanced data rates for GSM evolution (EDGE) radio access networks (GERAN) networks, ultra Mobile Broadband (UMB), EDGE networks, networks including any combination of Radio Access Technologies (RATs), such as multi-standard radio (MSR) base stations, multi-RAT base stations, etc., any third generation partnership project (3 GPP) cellular networks, wiFi networks, worldwide interoperability for microwave access (WiMax), or any cellular network or system, such as a system supporting equivalent functionality of the 5G update. The wireless communication network 100 may generally support MTC, eMTC, ioT and/or NB-IoT. Thus, while terms from 5G/NR and LTE may be used in this disclosure to exemplify embodiments herein, this should not be considered to limit the scope of embodiments herein to only the aforementioned systems.
The wireless communication network 100 may include a plurality of network nodes, with the network node 110 shown in the non-limiting example of fig. 2. The network node 110 is a radio network node. That is, a transmission point such as a radio base station, e.g. gNB, eNB, eNodeB or a home Node B, a home eNodeB or any other network Node with similar characteristics capable of serving user devices in the wireless communication network 100, such as wireless devices or machine type communication devices. In some examples, such as shown in fig. 2b, network node 110 may be a distributed node and may cooperate with virtual nodes 116 in cloud 115 to perform its functions in part.
The wireless communication network 100 may cover a geographical area, which in some embodiments may be divided into a plurality of cell areas, wherein each cell area may be served by a radio network node, although one radio network node may serve one or more cells. In the example of fig. 2, network node 110 serves cell 120. Based on the transmission power and thus the cell size, the network node 110 may belong to different categories such as e.g. macro eNodeB, home eNodeB or pico base station. In some examples, network node 110 may utilize a serving beam to serve a receiving node. The radio network node may support one or several communication technologies and its name may depend on the technology and terminology used. Any radio network node that may be comprised in the communication 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, with the wireless device 130 and one or more other wireless devices 140 shown in the non-limiting example of fig. 2. Any of the wireless devices 130 and one or more other wireless devices 140 included in the wireless communication network 100 may be a wireless communication device, such as a 5G UE or UE, which may also be referred to as, for example, a mobile terminal, a wireless terminal and/or mobile station, a mobile phone, a cellular phone, or a wireless-enabled laptop, just to mention a few further examples. Any of the wireless devices 130 and one or more other wireless devices 140 included in the wireless communication network 100 may be, for example, portable, pocket-storable, handheld, computer-containing, or vehicle-mounted mobile devices capable of transmitting voice and/or data via the RAN with another entity, such as a server, laptop, personal Digital Assistant (PDA) or tablet, machine-to-machine (M2M) device, sensor, ioT device, NB-IoT device, wireless interface-equipped device, such as a printer or file storage device, modem, or any other radio network unit capable of communicating over a radio link in a communication system. Any one of the wireless device 130 and one or more other wireless devices 140 included in the wireless communication network 100 are capable of wireless communication in the wireless communication network 100. The communication may be performed, for example, via the RAN and one or more core networks that may be included within the wireless communication network 100.
The wireless device 130 may be configured to communicate with the network node 110 within the wireless communication network 100 via a first link 141 (e.g., a radio link). The network node 110 may be configured to communicate with the virtual network node 116 within the wireless communication network 100 via a second link 142 (e.g., a radio link or a wired link). Any one of the one or more other wireless devices 140 may be configured to communicate with the network node 110 within the wireless communication network 100 over a respective first link (e.g., a radio link), which is not shown in fig. 2 for simplicity of the drawing.

In fig. 3, the optional actions are represented by dashed lines. These acts may be performed in a different order than shown in fig. 3.
Act 301
In this act 301, the wireless device 130 may obtain a configuration. The configuration may configure a set of resources to be used by wireless device 130 for transmission opportunities. Each resource may correspond to a configured license, such as a CG. The resource may be a transmission opportunity.
The set of resources may have correspondence to a plurality of beams or reference signals transmitted by the network node 110. The reference signal may be, for example, a Synchronization Signal Block (SSB), which may be transmitted by the network node 110.
The retrieval in this act 301 may include retrieving or retrieving from a memory and/or receiving 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 the 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 an RRCRelease message, which may be sent to the wireless device 130 when in a CONNECTED state to put the wireless device 130 in an inactive state, or alternatively, according to the second option, the configuration may be given in another dedicated RRC message, for example when the wireless device 130 may be in rrc_connected.
In a first set of examples, the set of configuration resources may be configured for wireless device 130 in accordance with act 301, wherein different CG transmission opportunities may have different SSB associations.
In some embodiments, one of the following options may be applied. According to a first option, the configuration may specify that each of the plurality of transmission occasions may correspond to a respective beam or reference signal. According to a second option, the correspondence between each of the plurality of transmission occasions and a respective beam or reference signal may be specified by a respective configuration. According to this option, the configuration may include a corresponding configuration for all transmission opportunities.
An example of two options for configuring CG resources is given below in fig. 5.
By receiving the configuration in this act 301, the wireless device 130 may associate the configured licensed resource configuration with a single or multiple SSBs of the cell 120.
Act 302
In this act 302, the wireless device 130 may receive a first indication from the network node 110. The first indication may indicate that the second resource of the group is deactivated. For example, according to this act 302, cg resources may be deactivated due to explicit release commands or implicit release commands in the DL, e.g., skipping n occasions, TA timers, etc. This can be understood to be different from a new command such as a conventional RRCRelease.
In some examples, the receiving in this act 302 may be performed via the first link 141.
In an alternative configuration, if each SSB or beam is configured with multiple CG-SDT configurations, one of the configurations may be active and the other may be considered "inactive" depending on the criteria on which the selected configuration is based.
In some embodiments, wireless device 130 may receive the first indication before wireless device 130 may perform act 303, i.e., before wireless device 130 may select on which resources it may perform the transmission. The wireless device 130 may then select which resources to use to transmit data to the network node 130 based on the received first indication. In other embodiments, this act 302 may not necessarily be performed after act 301 and before act 303. For example, it may be performed after act 305 and before act 306, as will be described later.
Act 303
In this act 303, the wireless device 130 may select the set of one or more first resources, i.e., the set of resources configured, based on one or more criteria.
Each of the one or more first resources may correspond to a configured license (CG).
From this act 303, the wireless device 130 may determine whether SDT using CG is applicable by estimating some or all of TA, data volume, and RSRP changes. The main problem to be solved may only occur if the beam that may be configured may not be the best beam, i.e. when the wireless device 130 may be moved to an inactive state. Selection between multiple CG configurations may be made based on, for example, priority configuration, transmission data size, configured RSRP threshold, and/or other criteria.
In some embodiments, one or more first resources may correspond to a beam. The one or more criteria may include one or more first resources corresponding to a beam having a highest SS-RSRP above a minimum threshold.
In some examples, according to this act 303, each time before executing a (CG) SDT, wireless device 130 may determine whether to use CG PUSCH resources configured based on the quality of the relevant SSB.
For example, for the first transmission on the configured CG resource, wireless device 130 may select the best CG resource, i.e., the resource corresponding to the beam on the configured carrier that may have the highest SS-RSRP above the minimum threshold. Alternatively, several CG resources may be selected that may be above a threshold.
By selecting the set of one or more first resources based on one or more criteria in this act 303, wireless device 130 is able to correct any potential uplink beam misalignment that may have occurred between network node 110 and wireless device 130. Thus, wireless device 130 may prevent network node 110 from possibly not listening for transmission grant occasions and beam directions. It is contemplated that in some examples, if the network node 110 has analog beamforming capabilities, the network node 110 can only listen for UL transmissions in one direction per antenna panel at a time.
Further, by selecting the set of one or more first resources based on the one or more criteria in this act 303, the wireless device 130 may then deactivate any unselected resources, such that the network node may avoid having to monitor UL transmissions (e.g., CG-SDT) from the wireless device in the entire set of resources (e.g., all configured beams) configured for transmission opportunities by the wireless device, which may be understood as processing requirements. For example, the network node can then avoid having to perform blind decoding on these resources.
Act 304
In this act 304, wireless device 130 may send a second indication to network node 110. The second indication may indicate the selected one or more first resources. According to this act 304, wireless device 130 may be required to indicate a beam change.
The sending in this act 304 may be performed via, for example, the first link 141.
As an alternative to transmitting the new best SSB indication using CG, the wireless device 130 may perform a random access procedure for this purpose.
In this act 304, by sending a second indication to the network node 110, the wireless device 130 may cause the network node 110 to avoid having to monitor UL transmissions, e.g., CG-SDT, from the wireless device 130 in all configured beams, which may be understood as processing requirements. Thus, wireless device 130 may enable network node 110 to more efficiently use resources in wireless communication network 100.
Act 305
In this act 305, the wireless device 130 transmits data, e.g., first data, to the network node 110 during an inactive state of the wireless device 130. The inactive state may be defined, for example, in 5G or in a newer system with equivalent functionality. The expression during the inactive state may be understood as meaning "when in the inactive state" or "when in the inactive state".
The first data may be user plane data.
The transmitting in act 305 is on one or more first resources selected from the group of resources configured for transmission occasions by wireless device 130.
The set of resources has correspondence with a plurality of beams or reference signals transmitted by the network node 110. The reference signal may be, for example, a Synchronization Signal Block (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 license.
The transmitting in act 305 may occur if the buffer size of wireless device 130 may be less than a threshold. The buffer may be a buffer for data transmission, which may be referred to herein as a transmission buffer.
The threshold may be the maximum size of the buffer (BS max ) Such as the maximum transmission buffer size.
The sending in this act 305 may be performed via, for example, the first link 141.
By transmitting data to the network node 110 on the selected one or more first resources, the wireless device 130 may cause the network node 110 to avoid having to monitor UL transmissions (e.g., CG-SDT) from the wireless device 130 throughout the set of resources (e.g., all configured beams) configured for transmission opportunities by the wireless device, which may be understood as processing requirements. Thus, when the transmission environment may change, for example, when the optimal beam (e.g., SSB) may change, the wireless device 130 may reduce the resources that may be required to perform data transmission (e.g., CG transmission) in an inactive state. The network node 110 is thereby able to more efficiently use the resources in the wireless communication network 100.
Act 306
In this act 306, the wireless device 130 sets the remaining unselected resources of the group to inactive. The remaining resources that are not selected may be one or more unselected transmission opportunities, and/or one or more unselected beams. Setting a resource to inactive may be understood to mean that the resource may still be configured but not used. That is, wireless device 130 may not transmit using inactive or deactivated resources, and thus network node 110 may be understood as not having to perform blind decoding on these resources. Later, the configuration (e.g., CG-SDT configuration) on these resources (e.g., beams) may be activated and used.
In some embodiments, the setting 306 of the remaining resources set to inactive may be based on the received first indication. For example, in these embodiments, the first indication may be received after act 305 and before act 306.
When the transmission is completed on the selected CG resources according to act 305, for example, wireless device 130 may need to set any other CG resources associated with other SSBs inactive for the UL carrier and release those CG resources according to act 306.
UL hopping can be used to deactivate unused CG configurations. In the case where several associations may be configured in the CG configuration, unused transmission opportunities in the CG configuration may be deactivated even if UL hopping is not applied to the selected and used beams.
There may be several beams above the threshold, and in one option, the CG resources of these beams may all be used. As described above, CG resources associated with beams below a threshold may not be used and deactivated.
By setting the unselected remaining resources of the group to inactive in this act 306, the wireless device 130 may cause the network node to avoid having to monitor UL transmissions (e.g., CG-SDT) from the wireless device throughout the set of resources (e.g., all configured beams) configured for transmission opportunities by the wireless device, which may be understood as processing requirements. For example, the network node can then avoid having to perform blind decoding on these resources.
Act 307
For DL transmissions, wireless device 130 may monitor a DL beam corresponding to a Receive (RX) beam used in selecting the appropriate SSB.
In this act 307, wireless device 130 may receive a third indication from network node 110. The third indication may indicate to release the unselected remaining resources that are set to inactive. For example, according to this act 307, cg resources may also be deactivated due to explicit release DL commands, or implicit DL commands, or implicitly, e.g., skipping n occasions, TA timers, etc. Releasing resources may be understood to mean that the configurations may be understood to be emptied, that is, if they are to be used later, it may be understood that the signaling to configure them needs to be sent again.
As a second set of examples, wireless device 130 may be configured with CG-SDT configurations associated with beams in which wireless device 130 may be located in a connected mode, and network node 110 may activate and retain CG-SDT configurations mapped to beams adjacent to the beam selected by wireless device 130, according to, for example, act 405, described later. In this case, when the wireless device 130 is at INACTIVE and one of the adjacent beams has a higher RSRP than the beam that the wireless device 130 is currently likely to use, the wireless device 130 may directly begin transmitting in the new beam. According to an action 405, which is described later, for example, the network node 110 may infer that the wireless device 130 has moved, and may update the active CG configuration by removing the configuration mapped to a beam that may no longer be adjacent to the new beam, by DL message, adding a new configuration for the now possibly adjacent beam, and it may update the TA according to this action 307. This may require network node 110 to monitor CG-SDT in all configured beams, which may be processing requirements, and alternatively network node 110 may monitor only one beam, and may require wireless device 130 to indicate a beam change in that beam, for example, according to acts 304 and 404, as described above.
By receiving the third indication in this act 307 to release the non-selected remaining resources set to inactive in act 306, the wireless device 130 can then release the inactive resources on command, thereby enabling the network node 110 to allocate the released resources to one or more other wireless devices 140. The network node 110 is thereby able to more efficiently use the resources in the wireless communication network 100. The improvements in spectral efficiency and resource utilization that may be obtained may be understood as being that wireless device 130 may be understood as not being able to use resources (e.g., CG-SDT resources on different SSBs) simultaneously. Releasing unused resources may be understood to mean that they may be used for other wireless devices and thus not wasted. The third indication is received by the wireless device 130 from the network node 110, which network node 110 may be aware of the load of the cell 120, as the network node 110 may be aware that it may need resources to allocate them to one or more other wireless devices 140, the wireless device 130 may only need to release the resources.
Act 308
In this act 308, the wireless device 130 may release the remaining resources that were not selected that were set to inactive.
The remaining resources set to inactive by release 308 may be based on the transmitted second indication. This may be because, for example, network node 110 may request that wireless device 130 release the remaining resources that were not indicated as having been selected by wireless device 130.
The release in act 308 may be based on the received third indication
If the active/used CG configuration is deactivated, e.g., according to act 306 and/or act 307, based on the above, e.g., SS-RSRP falls below a threshold, wireless device 130 may release the CG configuration according to act 308 and need to perform RACH after the CG configuration may be released to indicate a new best beam. Thus, it may receive a new CG configuration.
By releasing the remaining resources that were not selected that were set to inactive in this act 308, the wireless device 130 may then enable the network node 110 to allocate the released resources to one or more other wireless devices 140. The network node 110 is thereby able to more efficiently use the resources in the wireless communication network 100.
In alternative configurations, the CG-SDT configuration may contain specific several beam configurations, i.e. associated with different SSBs, one of the current best beams may be indicated as "active" and all other beams as inactive. In this case, even though wireless device 130 is not using these resources, these resources may still be reserved even though wireless device 130 may have been configured to release CG resources after multiple skipped transmissions.
Act 309
In this act 309, wireless device 130 may send a fourth indication to network node 110. The fourth indication may indicate that one or more selected first resources are to be changed. This may be because, for example, the wireless device 130 may have detected, for example, by performing measurements, that it may be understood that another beam corresponding to another transmission opportunity is stronger than the currently used beam.
The wireless device 130 may measure the SSB and if some condition is triggered, e.g., another SSB RSRP is higher than the currently selected SSB, the wireless device 130 may send an indication of this using the next CG transmission occasion according to this action 309. The indication may be, for example, a configuration index of the new strongest beam experienced by wireless device 130.
If the reporting criteria is triggered after the first transmission on the selected CG resource, wireless device 130 may send a fourth indication to notify network node 110 of this in accordance with act 309. The trigger condition may be whether the SS-RSRP of the selected CG resource falls below a threshold, or whether the SS-RSRP of another SSB becomes better than the SS-RSRP of the SSB of the selected RSRP resource.
The fourth indication may take the form of a new Medium Access Control (MAC) Control Element (CE) or otherwise encoded in a MAC Protocol Data Unit (PDU).
The fourth indication may be transmitted on the currently selected CG resource and may then be deactivated.
The sending in this act 309 may be performed via the first link 141.
In one option, the wireless device 130 may beamform the transmission in the direction of the old SSB, and in another option, the wireless device 130 may beamform the transmission in the direction of the new strongest SSB.
In one option, for this purpose, the wireless device 130 may have been configured with contention-free RA resources to indicate a new best SSB by preamble transmission only, according to act 309, for example.
By sending the fourth indication in this act 309, the wireless device 130 may let the network node 110 know which beam to listen to in order to receive the characteristic transmission from the wireless device 130, allowing the network node 110 to learn any changes implemented by the wireless device 130 so that the network node 110 can correctly and efficiently receive the data transmission of the wireless device 130.
Act 310
In this act 310, wireless device 130 may obtain a fifth indication from network node 110. The fifth indication may indicate a change from the selected one or more first resources to the one or more third resources of the group. The acquisition of the fifth indication may be based on the transmitted fourth indication.
The retrieval in this act 310 may include retrieving or retrieving from memory and/or receiving from the network node 110, e.g., via the first link 141.
In one option, for this purpose, the wireless device 130 may have been configured with contention-free RA resources to indicate a new best SSB by preamble transmission only, according to act 309, for example. With this option, the network node 110 may not need to respond with a random access response message containing UL grant. Instead, according to this act 310, the network node 110 may respond with an updated TA and new CG configuration. The response may be addressed to a C-RNTI that the wireless device 130 may have at the time of connection, or to a new RNTI.
Upon receiving the indication of the new best beam, according to this act 310, the network node 110 may reconfigure the wireless apparatus 130 with a new CG configuration having an SSB association that may correspond to the new best SSB. Such reconfiguration may only change the previous configuration, e.g., new time offset and SSB association. The DL message with the new configuration may also include a new TA because it may be assumed that the wireless device 130 has moved. The DL message may be used as an acknowledgement of the indication of the new best SSB sent from the wireless device 130.
In one example, beam reconfiguration may consist of the wireless device 130 from now on needing to treat it as a beam index of an "active" beam, and change the old beam to "inactive". If wireless device 130 has reported a new strongest beam index, as illustrated above, network node 110 may respond directly with the same beam index for reconfiguration in accordance with act 310. In other cases, network node 110 may base the change of beam on other measurements or inputs and there may be no beam reporting from wireless device 130 prior to beam reconfiguration. Network node 110 may indicate in the DL message an index to one of the CG resources configured but not activated 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 all or some of the previous configurations communicated in the RRCRelease message to have been outdated.
By obtaining the fifth indication in this act 310, wireless device 130 may obtain an acknowledgement from network node 110 that network node 110 may be aware of which beam to listen to, or it may receive a command to use a set of resources, e.g., a beam that network node 110 may consider more suitable for wireless device 130 to perform its UL transmission, which may make a set of resources other than those selected by wireless device 130 more suitable for wireless device 130 to use for UL transmission of data in an inactive state due to one or more measurements, e.g., interference measurements, performed by network node 110.
Act 311
In this act 311, the wireless device 130 may select one or more third resources of the group to transmit further data based on the obtained fifth indication.
An embodiment of the method performed by the network node 110 will now be described with reference to the flowchart shown in fig. 4. A method may be understood as processing data transmissions from wireless device 130. The network node 110 and the wireless device 139 operate in a wireless communication network 100.
In some embodiments, the wireless communication network 100 may support at least one of New Radio (NR), long Term Evolution (LTE), machine LTE (LTE-M), enhanced machine type communication (eMTC), and narrowband internet of things (NB-IoT).
The method can be understood as a computer-implemented method.
In some examples, the data may be "small data".
The method may include one or more of the following acts.
The method may include the following actions. In some embodiments, all actions may be performed. Where applicable, one or more embodiments may be combined. Components from one embodiment may be present by default in another embodiment, and it will be apparent to one skilled in the art how to use these components in other exemplary embodiments. For simplicity of description, not all possible combinations are described. A non-limiting example of a method performed by the network node 110 is depicted in fig. 4. In fig. 4, the optional actions are represented by dashed lines. These acts may be performed in a different order than shown in fig. 4.
With respect to the actions described for wireless device 130, the detailed description of some of the following corresponds to the same references provided above, and thus, for simplicity of description, will not be repeated here. For example, the one or more first resources may be one or more transmission opportunities, which may correspond to one or more beams and/or one or more reference signals.
Act 401
In this act 401, the network node 110 may send a configuration for configuring the set of resources to be used by the wireless device 130 for transmission opportunities.
The transmission of the configuration may be to the wireless device 130.
In some examples, one of the following may be applied: a) The configuration may specify that each of the plurality of transmission occasions corresponds to a respective beam or reference signal, and b) the correspondence between each of the plurality of transmission occasions and the respective beam or reference signal may be specified by the respective configuration. The configuration may include a corresponding configuration for all transmission occasions.
The configuration may be transmitted to the wireless device 130 in at least one of the following: i) A first message releasing the connection between the network node 110 and the wireless device 130, and ii) a second dedicated message.
The sending in this action 401 may be performed via, for example, the first link 141.
As previously described, in a first set of examples, the set of configuration resources may be configured for wireless device 130 according to, for example, act 301 and act 401, where different CG transmission opportunities may have different SSB associations. This configuration may be given in an RRCRelease message sent to the wireless device 130 when in a CONNECTED state to place the wireless device 130 in an inactive state, or alternatively, in another dedicated RRC message, such as when the wireless device 130 may be in rrc_connected.
Act 402
In this act 402, the network node 110 may send a first indication to the wireless device 130. The first indication may indicate that the second resource of the group is deactivated.
The sending in this action 403 may be performed via the first link 141.
According to this act 402, cg resources may be deactivated by explicit release DL commands or implicit DL commands, e.g., skipping n occasions, TA timers, etc.
Act 403
In this act 403, the network node 110 receives data, e.g., first data, from the wireless device 130 on one or more first resources during an inactive state of the wireless device 130. The inactive state may be defined, for example, in 5G or in a newer system with equivalent functionality.
The receiving in act 403 may be performed on one or more first resources. The first data may be user plane data.
The receiving in act 403 may occur if the size of the buffer of wireless device 130 is less than a threshold. The buffer may be a buffer for data transmission, which may be referred to herein as a transmission buffer.
The threshold may be the maximum size of the buffer (BS max ) Such as the maximum transmission buffer size.
The receiving in this act 403 may be performed via the first link 141.
The data reception in this act 403 may be based on the transmitted first indication.
Act 404
In this act 404, the network node 110 may receive a second indication from the wireless device 130. The second indication may indicate the selected one or more first resources.
The receiving in this act 404 may be performed via the first link 141.
Act 405
In this act 405, the network node 110 determines which one or more of the set of resources configured for transmission occasions by the wireless device 130 is one of: i) One or more first resources for transmitting data are selected by the wireless device 130, and/or ii) unused, unselected remaining resources, and iii) are set to inactive by the wireless device 130. The set of resources has correspondence with a plurality of beams or reference signals (e.g., synchronization Signal Blocks (SSBs)) transmitted by the network node 110.
The determination in act 405 may include, for example, calculation or derivation.
The determination in act 405 may be based on the received data 403, i.e., based on one or more first resources on which data may be received in act 403.
From this act 405, network node 110 may determine which CG configurations wireless device 130 may deactivate and thus be available to other users as a result of using CG resources associated with the SSB. The RX beam of network node 110 may be used to receive the UL transmission and, thus, network node 110 may infer which SSB wireless device 130 may select, or network node 110 may perform the determination in act 405 by using the configured CG transmission occasion-to-SSB mapping.
By the network node 110 determining which one or more of the set of resources configured for transmission occasions by the wireless device 130 has been selected by the wireless device 130 to transmit data, the network node 110 may be prevented from monitoring UL transmissions (e.g., CG-SDT) from the wireless device 130 throughout the set of resources (e.g., all configured beams) configured for transmission occasions by the wireless device 130, which may be understood as a processing requirement.
By the network node 110 determining which one or more of the set of resources of the wireless device 130 configured for the transmission occasion is not used, the remaining resources that are not selected or set to inactive by the wireless device, the network node can know which resources are available for allocation to one or more other wireless devices 140. Thus, the network node 110 is thereby able to more efficiently use resources in the wireless communication network 100, increase the capacity of the wireless communication network 100, and reduce its latency.
Act 406
In this act 406, the network node 110 may send a third indication to the wireless device 130. The third indication may indicate that the remaining resources not selected are released, e.g. set to inactive. For example, according to this act 406, cg resources may also be deactivated due to explicit release commands DL or implicit DL commands (e.g., skip n occasions, TA timers, etc.).
The sending in this act 406 may be based on the determination.
The sending of the third indication in this act 406 may be based on the received second indication.
The sending in this action 406 may be performed via the first link 141.
As explained later, in a second set of examples, wireless device 130 may be configured with CG-SDT configurations associated with beams in which wireless device 130 may be located in connected mode, and network node 110 may activate and retain CG-SDT configurations mapped to beams adjacent to the beam selected by wireless device 130 according to, for example, act 405. In this case, when the wireless device 130 is at INACTIVE and one of the adjacent beams has a higher RSRP than the beam that the wireless device 130 is currently likely to use, the wireless device 130 may directly begin transmitting in the new beam. From, for example, act 405, network node 110 may infer that wireless device 130 has moved and may update the active CG configuration by removing the configuration mapped to a beam that may no longer be adjacent to the new beam, by DL message, adding a new configuration for the now possibly adjacent beam, and it may update the TA, according to this act 406. This may require network node 110 to monitor CG-SDT in all configured beams, which may be processing requirements, and alternatively network node 110 may monitor only one beam, and may require wireless device 130 to indicate a beam change in that beam, for example, according to acts 304 and 404, as described above.
Act 407
In this act 407, the network node 110 may allocate the unselected remaining resources to one or more other wireless devices 140.
Allocation may be understood as, for example, dispatch.
Act 408
In this act 408, the network node 110 may receive a fourth indication from the wireless device 130. The fourth indication may indicate that one or more selected first resources are to be changed.
The receiving in act 408 may be performed via the first link 141.
As previously described, wireless device 130 may measure SSB and if a condition is triggered, such as another SSB RSRP being higher than the currently selected SSB, wireless device 130 may send an indication of this using the next CG transmission occasion in accordance with act 408. The indication may be, for example, a configuration index of the new strongest beam experienced by wireless device 130.
Act 409
In this action 409, the network node 110 may send a fifth indication to the wireless device 130. The fifth indication may indicate a change from the selected one or more first resources to the one or more third resources of the group.
A fifth indication may be sent to the wireless device 130.
The transmission in this act 409 may be performed via the first link 141.
As previously described, in one example, beam reconfiguration may consist of a beam index of the beam, where the wireless device 130 may need to be considered as "active" beam from now on, and change the old beam to "inactive". If the UE has reported a new strongest beam index, as illustrated above, then according to this action 409, the network node 110 may respond directly with the same beam index for reconfiguration. In other cases, network node 110 may base beam changes on other measurements or inputs and there may be no beam reports from wireless device 130 prior to beam reconfiguration. Network node 110 may indicate in the DL message an index to one of the CG resources configured but not activated 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 all or some of the previous configurations communicated in the RRCRelease message to have been outdated.
In one option, wireless device 130 may have been configured with contention-free RA resources for this purpose to indicate a new best SSB by preamble transmission only, according to, for example, acts 309 and 408. With this option, the network node 110 may not need to respond with a random access response message containing UL grant. Instead, network node 110 may respond with an updated TA and new CG configuration, e.g., in accordance with acts 409 and 310. The response may be addressed to a C-RNTI that the wireless device 130 may have at the time of connection, or to a new RNTI.
Upon receiving the indication of the new best beam, as per act 408, for example, network node 110 may reconfigure wireless apparatus 130 using the new CG configuration having an SSB association that may correspond to the new best SSB, as per acts 409 and 310, for example. Such reconfiguration may only change the previous configuration, e.g., new time offset and SSB association. The DL message with the new configuration may also include a new TA because it may be assumed that the wireless device 130 has moved. The DL message may be used as an acknowledgement of the indication of the new best SSB sent from the wireless device 130.
Fig. 5 is a schematic diagram of two options for configuring CG resources according to embodiments herein. In option 1, four different CG configurations are configured for wireless device 130, config#1, config#2, config#3, and config#4, wherein all CG transmission opportunities in the configuration correspond to associations with one beam SSB1-SSB 4. That is, each configuration may correspond to a particular SSB association. In the second option of fig. 5, one CG configuration, denoted "same configuration" in the figure, may contain different associations between CG transmission opportunities and beams SSB1-SSB 4. That is, different transmission opportunities may correspond to different SSB associations. In alternative examples, multiple CG transmission configurations may be configured for each associated SSB or beam.

Embodiments herein may be understood to be able to reduce the resources that may be required by the wireless device 130 to perform a data transmission (e.g., CG transmission) in an inactive state, such as when the optimal SSB may change.

The telecommunications network 1010 is itself connected to a host computer 1030, which host computer 1030 may be embodied as a stand-alone server, cloud-implemented server, hardware and/or software of a distributed server, or as processing resources in a server farm. Host computer 1030 may be owned or controlled by a service provider or may be operated by or on behalf of a service provider. The connections 1021 and 1022 between the telecommunications network 1010 and the host computer 1030 may extend directly from the core network 1014 to the host computer 1030, or may be via an optional intermediate network 1020. The intermediate network 1020 may be a combination of one or more of public, private, or hosted networks; intermediate network 1020 (if any) may be a backbone network or the internet; in particular, the intermediate network 1020 may include two or more subnetworks (not shown).
The communication system of fig. 10 as a whole enables a connection between connected UEs 1091, 1092 and a host computer 1030. This connection may be described as an Over The Top (OTT) connection 1050. Host computer 1030 and connected UEs 1091, 1092 are configured to transmit data and/or signaling via OTT connection 1050 using access network 1011, core network 1014, any intermediate network 1020, and possibly other 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 the routing of uplink and downlink communications. For example, the base station 1012 may not be notified or need to be notified of past routes of incoming downlink communications from the host computer 1030 that data is to be forwarded (e.g., handed off) to the connected UE 1091. Similarly, base station 1012 need not know the future route of outgoing uplink communications initiated from UE 1091 to host computer 1030.
With respect to fig. 11, 12, 13, 14, and 15, which are described below, it is to be understood that the UE is an example of a wireless device 130, and any description provided for the UE applies equally to the wireless device 130. It is also understood that a base station is an example of a network node 110, and any description provided for a base station applies equally to a network node 110.
