Description

Technical Field

[0001] This application relates to methods, apparatuses, systems, and computer programs, and in particular but not exclusively, to the allocation and signaling of configured authorization resources. Background Art

[0002] A communication system can be regarded as a facility that enables a communication session between two or more entities (such as user terminals, base stations, and / or other nodes) by providing a carrier between the various entities involved in the communication path. The communication system can be provided, for example, by a communication network and one or more compatible communication devices. The communication session can include, for example, data communication for carrying the communication, such as voice, video, email, text messages, multimedia, and / or content data, etc. Non-limiting examples of the services provided include two-way or multi-way calls, data communication or multimedia services, and access to a data network system (such as the Internet).

[0003] In a wireless communication system, at least a part of the communication session between at least two stations occurs over a wireless link. Examples of wireless systems include public land mobile networks (PLMNs), satellite-based communication systems, and different wireless local networks, such as wireless local area networks (WLANs). Some wireless systems can be divided into cells and are therefore commonly referred to as cellular systems.

[0004] A user can access the communication system through an appropriate communication device or terminal. The user's communication device can be referred to as a user equipment (UE) or user apparatus. The communication device is provided with appropriate signal receiving and transmitting means for enabling communication, for example, enabling access to the communication network or direct communication with other users. The communication device can access a carrier provided by a station (such as a base station of a cell) and transmit and / or receive communication on the carrier.

[0005] Communication systems and associated devices typically operate according to a given standard or specification that defines what the various entities associated with the system are allowed to do and how they should be implemented. The communication protocols and / or parameters to be used for the connection are also typically defined. An example of a communication system is UTRAN (3G radio). Other examples of communication systems are the long-term evolution (LTE) of the universal mobile telecommunications system (UMTS) radio access technology and the so-called 5G or new radio (NR) network. NR is being standardized by the 3rd Generation Partnership Project (3GPP). Summary of the Invention

In some embodiments, each function of the 5G RAN or 5GC includes a control device 200. In alternative embodiments, two or more functions of the 5G RAN or 5GC may share a control device.

[0115] Figure 3 shows an example of a terminal 300, such as Figure 1 the terminal shown. The terminal 300 may be provided by any device capable of transmitting and receiving radio signals. Non-limiting examples include a user equipment, a mobile station (MS) or a mobile device (such as a mobile phone or a so-called "smartphone"), a computer provided with a wireless interface card or other wireless interface facilities (such as a USB dongle), a personal digital assistant (PDA) or a tablet computer provided with wireless communication capabilities, a machine type communication (MTC) device, an Internet of Things (IoT) type communication device, or any combination of these devices or similar devices.

In Figure 3 it, the transceiver device is schematically designated by block 306. The transceiver device 306 may be provided, for example, by a radio section and an associated antenna arrangement.

[0117] The terminal 300 may be provided with at least one processor 301, at least one memory ROM 302a, at least one RAM 302b, and other possible components 303 for use in the software and hardware assisted execution of the tasks it is designed to perform, including control of access to and communication with access systems and other communication devices.

The device may optionally have a user interface such as a keyboard 305, a touch-sensitive screen or panel, a combination thereof, etc. Optionally, one or more displays, speakers, and microphones may be provided depending on the type of device.

[0119] Some examples of the present disclosure may be applied to situations where packet size changes occur between uplink transmission opportunities.

[0120] For example, in certain extended reality (XR) applications, different XR packets may have different sizes. XR may include virtual reality (VR), mixed reality (MR), or augmented reality (AR) applications.

[0121] To support XR, some network implementations for enhancing resource allocation and scheduling (including semi-persistent scheduling (SPS) and configured grant (CG) enhancements, as well as dynamic scheduling / grant enhancements) may be desired to help address packet size variations.

[0122] The size of a packet may be determined by a given data rate and frame rate, which may be modeled as a random variable following a truncated Gaussian distribution, with the following statistical parameters.

[0123] Table 1 (below) gives some of the parameters that may be used to model variable packet sizes:

[0124]

[0125]

[0126] Table 1 - Example parameters that may be used to model variable packet sizes

[0127] Considering the scenario where UL XR frames are carried via CG resources, variable packet sizes may pose problems because once the configuration (UL type 1 CG) and / or activation (UL type 2 CG) are completed, the resource size and MCS may be fixed.

[0128] Some examples can enhance CG transmission when supporting periodic traffic flows with variable packet sizes. Some examples can enable the UE to dynamically indicate unused CG physical uplink shared channel (PUSCH) resources (or CG PUSCH opportunities) within a CG period / duration.

[0129] In this context, CG resources are understood to be frequency resources available to the UE for uplink transmission to the network at a specific allocation time.

[0130] Although variable packet sizes in XR applications have been mentioned, it should be understood that the examples disclosed herein are not limited to XR applications and can be applied to other use cases outside of XR applications and provide similar advantages.

[0131] In some examples, due to the change in packet size, one or more CG PUSCH resources may not be used. Other situations where CG PUSCH resources may not be used include, for example, packet discard due to packet delay budget violation or PDU set priority considerations (e.g., if the base layer frame is discarded or fails, other dependent layers may be obsolete at least in some applications).

[0132] Some examples can address the question of whether and how enhanced CG candidate techniques are necessary and beneficial for improving XR capacity. Some examples may involve the dynamic indication of (multiple) CG PUSCH opportunities or (multiple) resources not used by the UE. Some examples can support the dynamic indication of (multiple) CG PUSCH opportunities or (multiple) resources not used by the UE. The dynamic indication can include: dynamic indication based on CG - uplink control information (UCI); dynamic indication based on new dedicated UCI; and / or dynamic indication based on media access control (MAC) control element (CE).

[0133] In some examples, if the access node (e.g., gNB) cannot correctly decode the first PUSCH carrying the buffer status report (BSR), there may be a problem of MAC CE loss for the dynamic indication based on MAC CE.

[0134] On the other hand, by using dynamic indication based on CG-UCI or dedicated UCI, some examples can enable a more robust channel coding to be selected for UCI transmission. Compared with the dynamic indication based on MAC CE, these examples can bring other benefits. For example, compared with UL PUSCH, UCI can be decoded earlier, thus resulting in an improvement in terms of latency.

[0135] Some examples can implement dynamic indication based on CG-UCI and / or dedicated UCI to address one or more of the above problems.

In some examples, obtaining the information indicating the preferred subset may include: at the user equipment, receiving, from the access node, the information indicating the preferred subset.

[0148] In some examples, the first message may include the information indicating the preferred subset. In some examples, the configuration information and / or the dynamic information may include the information indicating the preferred subset. The preferred subset may be pre-configured, for example, by pre-configuring such information that indicates the preferred subset does not include the last M resources.

[0149] In some examples, the content of the UCI may include one or more of the following fields:

[0150]

[0151]

[0152] Table 2 - Example CG-UCI fields

[0153] Some examples may provide a UCI that includes an indication of which (if any) CG PUSCH resources will be used. The UE may send this indication (e.g., as a UCI) to the network to indicate which (if any) CG PUSCH resources the UE will use (or will not use) within a given CG period / duration.

[0154] For example, the indication may include a plurality of bits, where a bit value of "1" may indicate that the resource has been used, and a bit value of "0" may indicate that the resource has not been used.

[0155] For example, in a case where there are 6 UL CG PUSCH opportunities within a CG period, the indication "111111" may be used to indicate that all 6 resources have been used, and the indication "111100" indicates that the first 4 resources have been used and the last 2 resources have not been used.

[0156] In some examples, the first CG PUSCH resource may be used by default. Thus, in such examples, the length of the indication may be M - 1, where M is the total number of CG PUSCH resources configured within a period.

[0157] In some examples, the UCI configuration may include an indication of unused CG PUSCH resources.

[0158] For example, when there are 6 UL CG PUSCH opportunities within a CG period, the indication may indicate which or how many opportunities are unused.

[0159] In an example where the first CG PUSCH resource is used, 3 bits may be used to indicate how many CG PUSCH resources will not be used in the current CG period. Table 3 below shows some example indicator values that may be used to indicate how many resources are unused.

[0160] 000 All resources are used 001 One CG PUSCH resource is not used 010 Two CG PUSCH resources are not used 011 Three CG PUSCH resources are not used 100 Four CG PUSCH resources are not used 101 Five CG PUSCH resources are not used 110 RES 111 RES

[0161] Table 3 - Example indicator values for different numbers of unused CG PUSCH resource opportunities

[0162] In some examples, the indicator may be used to indicate how many CG PUSCH resources will be used, rather than indicating how many CG PUSCH resources are unused. In some examples, both the UE and the gNB may know how many CG PUSCH resources are configured within a CG period, so an indicator that indicates how many resources are unused may also indicate how many resources are used, and vice versa.

[0163] In some examples, one or more of the reserved "RES" modes may be used as an indication that additional UL resources are needed. Based on this, the gNB may allocate UL resources for dynamic grant (DG) PUSCH transmission and / or may activate additional CG configurations. Advantageously, in such examples, the gNB may assign resources more quickly so that the packet delay budget can be met for delay-critical services.

[0164] In some examples, the proposed configuration may be extended to cover scenarios with multiple CG configurations.

[0165] For example, in the case where the UCI configuration includes an indication of which CG PUSCH resources will be adopted, the indication may be defined to cover the resources of the activated CG configurations for multiple CG configurations within a CG period. Similarly, in the case where the UCI configuration includes an indication of CG PUSCH resources that will not be used, the number of unused CG PUSCH resources for multiple CG configurations.

[0166] In some examples, data packets may not reach the start of the UL CG resources, for example due to possible jitter.

[0167] Some examples may define specific patterns (e.g., 111 in Table 3 above) that can be used for such scenarios. Alternatively, the UE may indicate the CG PUSCH resources that will be occupied exactly in the first CG PUSCH resource, and then later resource usage indications may overwrite the previous indication.

[0168] In some examples, the access node may configure the UE with information for performing dynamic indication. For example, an access node (such as a gNB) may configure the UE with information indicating one or more of the following parameters / rules:

[0169] · The number of bits carrying the dynamic indication;

[0170] · The PHY priority level of the dynamic indication;

[0171] o In some examples, the default setting is that the dynamic indication may have the same PHY priority as the CG PUSCH, but in other examples, the default may be that the dynamic indication can have a higher or lower priority than the CG PUSCH.

[0172] · The β-offset for multiplexing UL UCI with the CG PUSCH.

[0173] o In some examples, the default setting is that the β-offset can be the same as, for example, the β-offset used for multiplexing HARQ-ACK with the same PHY priority.

[0174] · The repetition of the dynamic indication over multiple CG PUSCH resources / timings.

[0175] · For the first CG PUSCH, no UL skipping.

[0176] · Later resource usage indications may overwrite the previous resource usage indications.

[0177] This configuration may be sent by the access node to the UE during CG PUSCH configuration and / or CG PUSCH configuration activation.

[0178] In some examples, this configuration may include information indicating a preferred subset of CG resources. For example, this information may indicate the rules for the UE to apply: in the case where the UE requires fewer resources than the available resources, how the UE can select pre-configured CG resources downward. For example, in the case where 6 UL CG PUSCH resources are configured, the UE may need to use fewer than 6 UL CG PUSCH resources.

[0179] In some examples, the information indicating a preferred subset of CG resources may include a bitmap of preferred and non-preferred resources (e.g., "111001" indicates that RE#1-3 and #6 are preferred while RE#4 and #5 are not), or information such as: the information indicates that the preferred subset includes the first N CG PUSCH resources (e.g., the value "3" may indicate that the first 3 CG PUSCH resources are preferred), or the last N CG PUSCH resources are not preferred (e.g., the value "3" may indicate that the last 3 CG PUSCH resources are not preferred).

[0180] Continuing with the previous example where 6 UL CG PUSCH resources are configured, in some examples, if only 1, 2, 3, 4, or 5 of these 6 PUSCH resources are needed, the configuration can inform the UE which ones to use. This can allow the gNB to configure UE#1 to use resource 110101 and configure UE#2 to use resource 101011, for example, when they only need 4 out of the 6 resources, thus ensuring minimal overlap / collision between them.

[0181] In some examples, a parameter indicating inference cancellation can be configured. By setting the value of such a parameter to, for example, "3", the parameter can indicate that the last 3 CG PUSCH opportunities are not used, unless the UE signals otherwise at the first CG opportunity. This can allow for some data savings.

[0182] In some examples, the UE may perform data transmission based on the information indicating the preferred subset. In some examples, the UE may use the preferred subset for transmission. For example, in the case where the information indicating the preferred subset includes a bitmap (such as "111001"), the UE may perform transmission using the first, second, third, and sixth CG PUSCH resources, but not the fourth and fifth CG PUSCH resources. Similarly, if the information indicating the preferred subset indicates that the last three CG PUSCH resources are not preferred, the UE may perform transmission using the first, second, and third CG PUSCH resources, but not the fourth, fifth, and sixth CG PUSCH resources.

[0183] In other examples, the UE may not use the preferred subset for transmission, for example when the UE needs more CG PUSCH resources (e.g., all CG PUSCH resources) for transmission.

[0184] In some examples, the PUCCH carrying HARQ-ACK bits may overlap with the dynamic indication. In such examples, the dynamic indication may be jointly encoded with the HARQ-ACK bits (e.g., when there is HARQ-ACK and the PHY priority is the same as the dynamic indication). In some examples, the joint encoding may reuse the HARQ-ACK resource element (RE) mapping for the combined indication bits and HARQ-ACK bits. The combined payload may be in the format of {indication bits, HARQ-ACK bits} or {HARQ-ACK bits, indication bits}, i.e., the format of concatenating the indication bits and HARQ-ACK bits.

[0185] In some examples, the dynamic indication may be encoded separately from the HARQ-ACK bits (e.g., when there is HARQ-ACK but has a different PHY priority from the dynamic indication). The applicable channel coding and RE mapping may depend on the relative priority between the HARQ-ACK and the indication bits.

[0186] For example, if the dynamic indication has a high priority, the encoding may include: reusing the traditional HARQ-ACK coding and RE mapping for the dynamic indication, and reusing the traditional channel state information (CSI) part 1 coding and RE mapping for the multiplexed HARQ-ACK. In the case where there is a limit on the maximum number of coding chains in the UL (e.g., there may be at most 3 separate coding chains), then in some examples, CSI part 2 may be discarded.

[0187] In some examples, there may be no overlap between the PUCCH carrying HARQ-ACK bits and the dynamic indication. In such examples, the dynamic indication bits may be treated with a higher priority than CSI, and coding and RE mapping similar to HARQ-ACK may be used.

[0188] It should be understood that the above examples can be applied to both the dynamic indication based on CG-UCI and the dynamic indication based on the new dedicated UCI.

[0189] Refer to Figure 5 , which shows a method according to certain examples.

[0190] Figure 5 The example scenario shown in may be used for the case where multiple PUSCHs are used for the transmission of one video frame. However, it should be understood that the signaling exchange can be applied to other example use cases. Figure 5 First, assume that the UE has an uplink data packet ready for transmission before the time of the first CG PUSCH resource.

[0191] At 500, an access node (e.g., gNB) provides configuration information to the UE. For example, the access node may configure one or more parameters / rules for reporting dynamic indications of unused CG PUSCH resources and corresponding UE behavior related to UL transmission. The configuration information may include information indicating that the UE will use UCI to report dynamic indications of unused CG PUSCH resources / timings.

[0192] At 502, the UE determines the number of CG resources required for the next data packet.

[0193] For example, when a data packet arrives or is ready on the UE side, the UE may determine how many CG PUSCH resources will be used to transmit the data packet.

[0194] In some examples, when UCI configuration information including information indicating how the UE can select down to use a subset of the configured resources is enabled, the UE may determine the number of CG resources based on this information.

[0195] In some examples, when UCI configuration information including information indicating implicit cancellation is enabled, the UE may not signal UCI bits if the uplink data exactly fits the remaining CG timings.

[0196] At 504, the UE sends a dynamic indication to the access node. The dynamic indication can be as described above. The dynamic indication can be multiplexed with CG PUSCH data.

[0197] At 506, the access node determines whether to reallocate resources for other purposes within the CG PUSCH resource period / duration based on the dynamic indication.

[0198] For example, when the access node determines that all CG PUSCH resources will be used, the access node can continue the reception process. However, when the access node determines that some CG PUSCH resources are not used, the access node can determine whether to reallocate the resources for other purposes.

[0199] Depending on the deployment scenario, it may not be possible to reallocate all unused resources for other purposes. In the worst case, if the access node does not have enough time to reschedule the unused CG resources, the access node can disable such reporting by, for example, not configuring such an operation.

[0200] As described above, in Figure 5In the above, it has been assumed that UL data is available before the first CG PUSCH resource. In some examples where the uplink data is ready after the first CG PUSCH resource, the UE can still send a dynamic indication and indicate that all CG resources in the current CG period will be used. In subsequent CG periods / slots, if necessary, the UE can send a new dynamic indication to overwrite an earlier dynamic indication. The new dynamic indication may be limited to not indicating a smaller number of unused CG PUSCH resources compared to the earlier indication. In other words, in a situation where the UE has indicated to the access node that some CGPUSCH resources can be released for other purposes, the UE cannot claim these resources.

[0201] Accordingly, a method for supporting the UE to indicate unused CG PUSCH resources to the access node has been described. Such a method may be reliable and fast, and may allow the access node to have the opportunity to reallocate the unused resources for other purposes, thereby improving the efficiency of the network.

[0202] In some examples, a device includes: at a user equipment, receiving a first message from an access node, the first message including information indicating configured authorized uplink resources for performing uplink data transmission to the access node; receiving, at the user equipment from the access node, configuration information for sending a dynamic indication, the dynamic indication including: information indicating unused configured authorized uplink resources; obtaining information indicating a preferred subset of the configured authorized uplink resources; sending uplink data from the user equipment to the access node based on the information indicating the configured authorized uplink resources and the preferred subset; and sending a dynamic indication from the user equipment to the access node based on the configuration information.

[0205] In some examples, the apparatus includes at least one processor and at least one memory, the at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus to at least: send a first message to a user equipment, the first message including information indicating a configured authorized uplink resource, the configured authorized uplink resource being for the user equipment to perform uplink data transmission to the access node; send configuration information to the user equipment, the configuration information being for causing the user equipment to send a dynamic indication, the dynamic indication including: information indicating an unused configured authorized uplink resource; provide the user equipment with information indicating a preferred subset of the configured authorized uplink resources; receive uplink data from the user equipment based on the information indicating the configured authorized uplink resource and the preferred subset; and receive the dynamic indication from the user equipment based on the configuration information
