MULTIPLE PUSCHS AND MULTIPLE PDSCHS BUNDLE TRANSMSSIONTECHNICAL FIELD
[0001] The present disclosure relates to wireless communications, and more specifically to a user equipment (UE) , a processor for wireless communication, a base station, methods, and a computer readable medium for multiple PUSCHs and multiple PDSCHs bundle transmission.BACKGROUND
[0002] A wireless communications system may include one or multiple network communication devices, such as base stations, which may be otherwise known as an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. Each network communication devices, such as a base station may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE) , or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) . Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G) ) .
[0003] Xtended Reality (XR) is a broad term covering Augmented Reality (AR) , Mixed Reality (MR) and Virtual Reality (VR) . Multiple XR devices would be required for immersive XR services, e.g., a pair of glasses and haptic devices. Data streams from multiple XR devices are closely related and require strongly coordinated transmission for application synchronization. A gNB or UE should be aware of the correlated flows of multi-modal communication service, and then guarantees the transmission performances of the correlated flows jointly. The user experience for multi-modal communication service is hard to be satisfied when the correlated flows are treated separately.
[0004] Considering the latency requirement of XR service, configured grant (CG) physical uplink shared channels (PUSCH) and semi-persistent scheduling (SPS) physical downlink shared channels (PDSCH) would be used for XR transmission because less downlink control information (DCI) would be transmitted and no scheduling request (SR) needs to be transmitted, and thus the latency would be guaranteed. However, how to realize the multiple correlated PUSCH transmissions, multiple correlated PDSCHs transmissions and multiple correlated PUSCH transmission and PDSCH transmission has not been studied yet.SUMMARY

[0053] Principles of the present disclosure will now be described with reference to some embodiments. It is to be understood that these embodiments are described only for the purpose of illustration and help those skilled in the art to understand and implement the present disclosure, without suggesting any limitation as to the scope of the disclosure. The disclosure described herein can be implemented in various manners other than the ones described below. In the following description and claims, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skills in the art to which this disclosure belongs.
[0054] References in the present disclosure to “one embodiment, ” “an example embodiment, ” “an embodiment, ” “some embodiments, ” and the like indicate that the embodiment (s) described may include a particular feature, structure, or characteristic, but it is not necessary that every embodiment includes the particular feature, structure, or characteristic. Moreover, such phrases do not necessarily refer to the same embodiment (s) . Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
[0055] It shall be understood that although the terms “first” and “second” or the like may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. For example, a first element could also be termed as a second element, and similarly, a second element could also be termed as a first element, without departing from the scope of embodiments. As used herein, the term “and / or” includes any and all combinations of one or more of the listed terms. In some examples, values, procedures, or apparatuses are referred to as “best, ” “lowest, ” “highest, ” “minimum, ” “maximum, ” or the like. It will be appreciated that such descriptions are intended to indicate that a selection among many used functional alternatives can be made, and such selections need not be better, smaller, higher, or otherwise preferable to other selections.
[0056] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of embodiments. As used herein, the singular forms “a, ” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises, ” “comprising, ” “has, ” “having, ” “includes” and / or “including, ” when used herein, specify the presence of stated features, elements, components and / or the like, but do not preclude the presence or addition of one or more other features, elements, components and / or combinations thereof.

[0057] PUSCH transmission (s) may correspond to a configured grant (CG) Type 1 or Type 2. The configured grant Type 1 PUSCH transmission is semi-statically configured to operate upon the reception of higher layer parameter of configuredGrantConfig including rrc-ConfiguredUplinkGrant without the detection of an uplink (UL) grant in a downlink control information (DCI) . The higher layer parameter could configure time domain resource location by indicating a start-length-indicator-value (SLIV) from a configured time domain resource allocation (TDRA) table and frequency domain location for the PUSCH transmission in a period, and the resource could be used in each period.
[0058] The configured grant Type 2 PUSCH transmission is semi-persistently scheduled by an activation DCI after the reception of higher layer parameter configuredGrantConfig not including rrc-ConfiguredUplinkGrant. The time domain resource and the frequency domain resource of the PUSCH in a period is indicated by the activation DCI. Multiple CG type 2 configurations may be configured and one of them may be activated by the HPN (HARQ process number) field indicating the configuration index in the activation DCI.
[0059] A UE may be configured one or multiple SPS configurations, and for each SPS configuration, a period P, and an index could be provided. The UE may receive an activating DCI to activate a SPS configuration from one or multiple SPS configurations. Also, the DCI may indicate the time domain resource and frequency domain resource of SPS PDSCH for the activated SPS configuration. Multiple SPS configurations may be configured and one of them may be activated by the HPN field indicating the configuration index in the activation DCI.
[0060] As mentioned above, Xtended Reality (XR) covers Augmented Reality (AR) , Mixed Reality (MR) and Virtual Reality (VR) . Along with cloud computing, XR applications typically require high throughput and low latency, and have a big packet size and variable data packet size. To realize the low latency requirement and the big packet size, it has been decided in 3GPP to configure multiple CG PUSCH transmission occasions (TOs) in a period of a single CG PUSCH configuration. A gNB may configure a parameter N and indicate a single start-length-indicator-value (SLIV) from a configured time domain resource allocation (TDRA) table, and UE may determine N resource (s) in in each of N consecutive slots per CG period, and each resource has same SLIV in the slot. UE could be configured one or multiple CG configurations, and for each CG configuration, a configuration index, a period P and N could be configured separately. In some scenarios, some resource may be not used by the UE, and the UE may send an indication to gNB to indication which TO is unused by the UE. The indication is carried in UCI, and such UCI may be called unused TO indication UCI (UTO-UCI) . The indication may be a bitmap, and each bit in the bitmap is corresponding to one TO in a configured window and each bit in the bitmap is used to indicate the corresponding TO in the window is unused or not.
[0061] Data streams from multiple XR devices are closely related and require strongly coordinated transmission for application synchronization. A gNB or UE should be aware of the correlated flows of multi-modal communication service, and then guarantee the transmission performances of the correlated flows jointly. The user experience for multi-modal communication service is hard to be satisfied when the correlated flows are treated separately. It means that multiple correlated PUSCH transmissions or multiple correlated PDSCHs transmissions and multiple correlated PUSCH transmission and PDSCH transmission should be realized to guarantee correlated flows could be treated jointly and to improve UE experience. How to realize the multiple correlated PUSCH transmissions or multiple correlated PDSCHs transmissions and multiple correlated PUSCH transmission and PDSCH transmission should be studied and supported.
[0062] Considering the latency requirement of XR service, the CG PUSCH and SPS PDSCH may be used for XR transmission because there is less DCI transmitted and no scheduling requests need to be transmitted, and therefore the latency would be guarantee. In view of this, how to realize multiple bundle CG PUSCH transmissions and multiple bundle SPS PDSCH transmission and CG PUSCH transmission bundle with SPS PDSCH transmission needs to be solved.
[0063] Solutions are proposed to realize multiple bundled CG PUSCH transmissions, multiple bundled SPS PDSCH transmission, or CG PUSCH transmission (s) bundled with SPS PDSCH transmission (s) . According to embodiments of the present disclosure, a UE may receive from a base station one or more configured grant (CG) configurations for PUSCH transmission and / or one or more SPS configurations for PDSCH reception. The UE may determine a bundle of resources for PUSCH transmission and / or for SPS PDSCH reception. The UE may further perform the CG PUSCH transmission and / or the SPS PDSCH reception in the bundle of resource. In this way, the UE can bundle multiple resources for multiple PUSCH and / or PDSCH for transmission or reception, and gNB could identify the PUSCH reception and / or PDSCH transmission are bundle in the bundled multiple resources, thus guarantee transmission performances of the correlated flows jointly.
[0064] Aspects of the present disclosure are described in the context of a wireless communications system. FIG. 1 illustrates an example of a wireless communications system 100 in which some embodiments of the present disclosure can be implemented. The wireless communications system 100 may include one or more network entities 102 (also referred to as network equipment (NE) ) , one or more UEs 104, a core network 106, and a packet data network 108. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE-Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a 5G network, such as an NR network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 502.11 (Wi-Fi) , IEEE 502.16 (WiMAX) , IEEE 502.20. The wireless communications system 100 may support radio access technologies beyond 5G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA) , frequency division multiple access (FDMA) , or code division multiple access (CDMA) , etc.
[0065] The one or more network entities 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the network entities 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a radio access network (RAN) , a base transceiver station, an access point, a NodeB, an eNodeB (eNB) , a next-generation NodeB (gNB) , or other suitable terminology. A network entity 102 and a UE 104 may communicate via a communication link 110, which may be a wireless or wired connection. For example, a network entity 102 and a UE 104 may perform wireless communication (e.g., receive signaling, transmit signaling) over a Uu interface. In a 3GPP non-terrestrial network (NTN) , a network entity 102 in form of a satellite can directly communicate to UE 104 using NR / LTE Uu interface. The satellite may be a transparent satellite or a regenerative satellite. For NTN with a transparent satellite, a base station on earth may communicate with a UE via the satellite. For NTN with a regenerative satellite, the base station may be on board and directly communicate with the UE.
[0066] A network entity 102 may provide a geographic coverage area 112 for which the network entity 102 may support services (e.g., voice, video, packet data, messaging, broadcast, etc. ) for one or more UEs 104 within the geographic coverage area 112. For example, a network entity 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc. ) according to one or multiple radio access technologies. In some implementations, a network entity 102 may be moveable, for example, a satellite associated with a non-terrestrial network. In some implementations, different geographic coverage areas 112 associated with the same or different radio access technologies may overlap, but the different geographic coverage areas 112 may be associated with different network entities 102. Information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.
[0067] The one or more UEs 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a mobile device, a wireless device, a remote device, a remote unit, a handheld device, or a subscriber device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (IoT) device, an Internet-of-Everything (IoE) device, or machine-type communication (MTC) device, among other examples. In some implementations, a UE 104 may be stationary in the wireless communications system 100. In some other implementations, a UE 104 may be mobile in the wireless communications system 100.
[0068] The one or more UEs 104 may be devices in different forms or having different capabilities. Some examples of UEs 104 are illustrated in FIG. 1. A UE 104 may be capable of communicating with various types of devices, such as the network entities 102, other UEs 104, or network equipment (e.g., the core network 106, the packet data network 108, a relay device, an integrated access and backhaul (IAB) node, or another network equipment) , as shown in FIG. 1. Additionally, or alternatively, a UE 104 may support communication with other network entities 102 or UEs 104, which may act as relays in the wireless communications system 100.
[0069] A UE 104 may also be able to support wireless communication directly with other UEs 104 over a communication link 114. For example, a UE 104 may support wireless communication directly with another UE 104 over a device-to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link 114 may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0070] A network entity 102 may support communications with the core network 106, or with another network entity 102, or both. For example, a network entity 102 may interface with the core network 106 through one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The network entities 102 may communicate with each other over the backhaul links 116 (e.g., via an X2, Xn, or another network interface) . In some implementations, the network entities 102 may communicate with each other directly (e.g., between the network entities 102) . In some other implementations, the network entities 102 may communicate with each other or indirectly (e.g., via the core network 106) . In some implementations, one or more network entities 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC) . An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs) .
[0071] In some implementations, a network entity 102 may be configured in a disaggregated architecture, which may be configured to utilize a protocol stack physically or logically distributed among two or more network entities 102, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 102 may include one or more of a central unit (CU) , a distributed unit (DU) , a radio unit (RU) , a RAN Intelligent Controller (RIC) (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, or any combination thereof.
[0072] An RU may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 102 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 102 may be located in distributed locations (e.g., separate physical locations) . In some implementations, one or more network entities 102 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0073] Split of functionality between a CU, a DU, and an RU may be flexible and may support different functionalities depending upon which functions (e.g., network layer functions, protocol layer functions, baseband functions, radio frequency functions, and any combinations thereof) are performed at a CU, a DU, or an RU. For example, a functional split of a protocol stack may be employed between a CU and a DU such that the CU may support one or more layers of the protocol stack and the DU may support one or more different layers of the protocol stack. In some implementations, the CU may host upper protocol layer (e.g., a layer 3 (L3) , a layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaption protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU may be connected to one or more DUs or RUs, and the one or more DUs or RUs may host lower protocol layers, such as a layer 1 (L1) (e.g., physical (PHY) layer) or an L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160.
[0074] Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU and an RU such that the DU may support one or more layers of the protocol stack and the RU may support one or more different layers of the protocol stack. The DU may support one or multiple different cells (e.g., via one or more RUs) . In some implementations, a functional split between a CU and a DU, or between a DU and an RU may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU, a DU, or an RU, while other functions of the protocol layer are performed by a different one of the CU, the DU, or the RU) .
[0075] A CU may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU may be connected to one or more DUs via a midhaul communication link (e.g., F1, F1-c, F1-u) , and a DU may be connected to one or more RUs via a fronthaul communication link (e.g., open fronthaul (FH) interface) . In some implementations, a midhaul communication link or a fronthaul communication link may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 102 that are in communication via such communication links.
[0076] The core network 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The core network 106 may be an evolved packet core (EPC) , or a 5G core (5GC) , which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management functions (AMF) ) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc. ) for the one or more UEs 104 served by the one or more network entities 102 associated with the core network 106.
[0077] The core network 106 may communicate with the packet data network 108 over one or more backhaul links 116 (e.g., via an S1, N2, N2, or another network interface) . The packet data network 108 may include an application server 118. In some implementations, one or more UEs 104 may communicate with the application server 118. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the core network 106 via a network entity 102. The core network 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server 118 using the established session (e.g., the established PDU session) . The PDU session may be an example of a logical connection between the UE 104 and the core network 106 (e.g., one or more network functions of the core network 106) .
[0078] In the wireless communications system 100, the network entities 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers) ) to perform various operations (e.g., wireless communications) . In some implementations, the network entities 102 and the UEs 104 may support different resource structures. For example, the network entities 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the network entities 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5G and among other suitable radio access technologies, the network entities 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures) . The network entities 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0079] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., μ=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., μ=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., μ=1) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., μ=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., μ=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., μ=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0080] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames) . Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0081] Additionally or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., μ=0, μ=1, μ=2, μ=3, μ=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols) . In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing) , a slot may include 12 symbols. The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., μ=0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0082] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz –7.125 GHz) , FR2 (24.25 GHz –52.6 GHz) , FR3 (7.125 GHz –24.25 GHz) , FR4 (52.6 GHz –114.25 GHz) , FR4a or FR4-1 (52.6 GHz –71 GHz) , and FR5 (114.25 GHz –300 GHz) . In some implementations, the network entities 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the network entities 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data) . In some implementations, FR2 may be used by the network entities 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0083] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies) . For example, FR1 may be associated with a first numerology (e.g., μ=0) , which includes 15 kHz subcarrier spacing; a second numerology (e.g., μ=1) , which includes 30 kHz subcarrier spacing; and a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies) . For example, FR2 may be associated with a third numerology (e.g., μ=2) , which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., μ=3) , which includes 120 kHz subcarrier spacing.
[0084] FIG. 2 illustrates an example of a process flow of transmission and reception of multiple resources in bundle in accordance with some example embodiments of the present disclosure. The process flow 200 may involve a UE 201 and a base station 202. The process flow 200 may be applied to the wireless communications system 100 with reference to FIG. 1, for example, the UE 201 may be any of UEs 104, and the base station 202 may be any of the network entities 102. It would be appreciated that the process flow 200 may be applied to other communication scenarios.
[0085] At 210, the base station 202 transmits, to the UE 201, one or more CG configurations for PUSCH reception and / or one or more SPS configurations for PDSCH transmission 215. Accordingly, the UE 201 receives, from the base station 202, the one or more CG configurations for PUSCH transmission and / or one or more SPS configurations for PDSCH reception 215. For each of the CG configuration (s) and SPS configuration (s) , a corresponding period, at least one resource in one period, and a configuration index is indicated.
[0086] At 230, the UE 201 determines a bundle of resources for PUSCH transmission and / or for SPS PDSCH reception. Correspondingly, at 240, the base station 202 determines a bundle of resources for PUSCH reception and / or for SPS PDSCH transmission. It can be understood that the process for the UE 201 to determine a bundle of resources is also applicable to the base station.
[0087] At 250, the UE 201 performs the CG PUSCH transmission and / or the SPS PDSCH reception in the bundle of resources 255. Correspondingly, at 260, the base station 202 performs the CG PUSCH reception and / or the SPS PDSCH transmission in the bundle of resources 255.
[0088] In some embodiments, the bundle of resources may be determined based on a time window. The UE 201 may a bundle of resources for CG PUSCH transmission and / or for SPS PDSCH reception in the time window. The time window may be a predefined or indicated by the base station. The time window may be one or multiple time units, wherein the time unit may be a slot, a frame, a subframe or a symbol, and the like.
[0089] To determine the bundle of resources for CG PUSCH transmission, the UE 201 may transmit a signaling indicative of the bundle of resources for the CG PUSCH transmission. The signaling may be carried in an uplink control information (UCI) in CG PUSCH. In some embodiments, the UCI may be unused transmission occasion UCI (UTO-UCI) .
[0090] In some embodiments, the number of bits of the signaling may be configured by the base station 202 or the number of bits may be predefined. The bit field may takes effect in the time window, to indicate the PUSCH is belong to which bundle in the time window. In some embodiments, the time window of the bundle of resources may be the same as a window for UTO indication, or the window for UTO indication is multiple times of the time window of the bundle of resources.
[0091] As an example, a signaling transmit in PUSCH 1 indicate PUSCH 1 is bundle 1 in a time domain window. a signaling transmit in PUSCH 2 indicate PUSCH 2 is bundle 2 in the time domain window. a signaling transmit in PUSCH 3 indicate PUSCH 3 is bundle 1 in the time domain window. a signaling transmit in PUSCH 4 indicate PUSCH 4 is bundle 2 in a time domain window. This means PUSCH 1 and PUSCH 3 are bundled, and PUSCH 2 and PUSCH 4 are bundled.
[0092] Alternatively or additionally, the UE 201 may receive a signalling from the base station 202 to determine that multiple CG PUSCH configuration are bundled, or multiple SPS PDSCH configurations are bundled, or one or multiple CG PUSCH configurations and one or more SPS PDSCH configurations is bundled. The signaling may be indicative of bundled configurations among the one or more CG configurations and / or the one or more SPS configurations 215. Based on the signaling, the UE 201 may determine a bundle of resources as multiple resources corresponding to the bundled configurations.
[0093] In some embodiments, for each CG or SPS configuration, the signalling may configure the CG or SPS configuration with at least one index of the other bundled CG configuration (s) or SPS configuration (s) . For example, for CG configuration 1, the signalling configures it with the bundled CG configurations indexes including CG configuration 2, CG configuration 3, and for CG configuration 2, the signalling configures it with the bundled CG configurations indexes including CG configuration 1 and CG configuration 3, and for CG configuration 3, the signalling configures it with the bundled CG configurations indexes including CG configuration 1 and CG configuration 2. This means CG configurations 1, 2, and 3 are bundled.
[0094] As another example, for SPS configuration 1, the signalling configures it with bundled SPS configurations indexes including SPS configuration 2 and SPS configuration 3, and for CG configuration 2, the signalling configures it with the bundled SPS configurations indexes including SPS configuration 1 and SPS configuration 3; and for SPS configuration 3, the signalling configures it the bundled SPS configurations indexes including SPS configuration 1 and SPS configuration 2. This means SPS configurations 1, 2 and 3 are bundled.
[0095] As a further example, for CG configuration 1, the signaling configures with the bundled CG configurations indexes including CG configuration 2 and SPS configuration 1; and for CG configuration 2, the signaling configures with the bundled CG configurations indexes including CG configuration 1 and SPS configuration 1, and for SPS configuration 1, the signaling configures with the bundled CG configurations indexes including CG configurations 1 and 2. This means SPS configuration 1 and CG configurations 1 and 2 are bundled.
[0096] Alternatively or additionally, for each CG or SPS configuration, the signalling may configure it with a bundle index. The CG or SPS configurations with a same bundle index are bundled. For example, for CG configuration 1, the signalling configures it with the bundle index “1” ; and for CG configuration 2, the signalling configures it with the bundle index “2” ; for CG configuration 3, the signalling configures it with the bundle index “1” ; and for CG configuration 4, the signalling configures it with the bundle index “2” ; . This means CG configuration 1 and CG configuration 3 are bundled and CG configuration 2 and CG configuration 4 are bundled.
[0097] As another example, for SPS configuration 1, the signalling configures it with the bundle index “1” ; and for SPS configuration 2, the signalling configures it with the bundle index “2” ; for SPS configuration 3, the signalling configures it with the bundle index “1” ; and for SPS configuration 4, the signalling configures it with the bundle index “2” . This means SPS configuration 1 and SPS configuration 3 are bundled, and SPS configuration 2 and SPS configuration 4 are bundled.
[0098] As a further example, for CG configuration 1, the signalling configures it with the bundle index “1” ; and for CG configuration 2, the signalling configures it with the bundle index “2” ; for SPS configuration 1, the signalling configures it with the bundle index “1” ; and for SPS configuration 2, the signalling configures it with the bundle index “2” . This means CG configuration 1 and SPS configuration 1 are bundled, and CG configuration 2 and SPS configuration 4 are bundled.
[0099] Alternatively or additionally, the signalling may configure a table or a set of configuration group. Each row of the table or each element of the set may indicate multiple CG configurations and / or multiple SPS configurations which are bundled. An example of the table or the set of configuration group is provided as below.
[0100] Table 1
[0101] In some embodiments, the signalling indicative of the bundled CG or SPS configurations may be carried in a radio resource control (RRC) message or downlink control information (DCI) . In some embodiments, the bundled configurations may have a same periodicity, or have periodicities multiple time than each other.
[0102] The bundled multiple resources for CG PUSCH transmission and / or for SPS PDSCH reception in a time window is the multiple resources in a time window corresponding to bundled CG PUSCH configuration (s) and / or SPS PDSCH configuration (s) . The UE 201 and the base station 202 may determine the resource for a CG configuration based on a parameter N indicating a number of transmission occasions in a period and a parameter indicating a SLIV from a configured time domain resource allocation (TDRA) table.
[0103] In some embodiments, UE 201 may determine resources of the bundled configurations based on a number of transmission occasion (TOs) in a periodicity and SLIV information respectively. The UE 201 may determine the bundle of resources as the resources of the bundled configurations.
[0104] FIG. 3A illustrates a schematic diagram of transmission occasions (TOs) in a period of a CG PUSCH configuration in accordance with some example embodiments of the present disclosure. Assuming the period of the CG configuration is 6 slots, and N=4, and a SLIV is indicated, then the determined N TOs in a CG period could be shown in FIG. 3. The UE 201 may determine N resources of the CG configuration in each of N consecutive slots per CG period based on the parameter N and the SLIV. Each resource has same SLIV in the slot. The resource for a SPS PDSCH configuration may be determined using the similar method as the CG configuration. A parameter N and a parameter indicating a single SLIV from a configured TDRA table may be configured. The UE 201 may determine N resource in each of N consecutive slots per SPS period, and each resource has same SLIV in the slot.
[0105] FIG. 3B illustrates a schematic diagram of an example bundle of resources for multiple CG configurations in a one slot time window in accordance with some example embodiments of the present disclosure. In the FIG. 3B, assuming the size of the time window is one slot, and assuming CG configuration 1 and CG configuration 2 and CG configuration 3 are bundled, and UE could determine that in a slot, the resource for CG configuration 1 and the resource for CG configuration 2 and 3 is bundled resources. In FIG. 3B the resources for CG configurations 1, 2, and 3 have a same periodicity of 1 slot, and the time window is also one slot.
[0106] FIG. 3C illustrates a schematic diagram of an example bundle of resources for multiple CG configurations in a two slot time window in accordance with some example embodiments of the present disclosure. In the FIG. 3C, assuming the size of the time window is 2 slots, and assuming CG configuration 1 and CG configuration 2 and CG configuration 3 are bundled, and UE could determine that in a slot, the resource for CG configuration 1 and the resource for CG configuration 2 and 3 is bundled resources. In FIG. 3C, the resources for CG configurations 1 and 3 have the periodicity of 1 slot, for CG configuration 2 have the periodicity of 2 slots. The time window is 2 slots, same as the periodicity for CG configuration 2, and two times than the periodicity for CG configurations 1 and 3.
[0107] When one or more CG type 2 configurations and / or one or more SPS configurations are bundled, the bundled configurations may be jointly activated. That is, if at least one of the configuration is activated, all the configurations in the bundle are activated. The UE 201 may activate all of the bundled CG type 2 configurations and / or all of the bundled SPS configuration, based on determining that any of the one or more CG type 2 configurations and / or the one or more SPS configuration is activated. Alternatively, only if all the configurations are activated, then the bundle is activated and may be used for the transmission and or reception. The UE 201 may accordingly determine that resources of the bundled configurations are enabled for transmission or reception in bundle, based on determining that all of the one or more CG type 2 configurations and / or the one or more SPS configuration are activated.
[0108] When one or more CG type 2 configuration and / or one or more SPS configuration is bundled with a CG type 1 configuration, the bundled configurations may be jointly activated. The UE 201 may activate the one or more CG type 1 configurations, based on determining that any of the one or more CG type 2 configurations and / or the one or more SPS configuration is activated. Alternatively, the bundle is activated and can be used for the transmission or reception only if all the all the CG type 2 configuration and / or all the SPS configuration is activated. Accordingly, the UE 201 may activate the one or more CG type 1 configurations, based on determining that all of one or more CG type 2 configurations and / or the one or more SPS configuration are activated. Thus, the bundled resources for such bundled configurations are activated after all the CG type 2 configuration and / or all the SPS configuration are activated. The resource for CG type 1 is activated at the slot in or after the slot where all the CG type 2 configuration and / or all the SPS configuration is activated.
[0109] Refer back to FIG. 2. Alternatively and additionally, the UE 201 may determine a bundle of resources for one CG or SPS configuration. In some embodiments, the UE 210 may receive a signaling from the bases station 202, which indicates multiple resources in a slot or indicates multiple resource in a group or slots, for the CG configuration or SPS configuration. The UE 201 may determine that the multiple resources in a time window are bundled. In some embodiments, the signaling may comprise a SLIV information of the multiple resources in a slot or in a group of slots.
[0110] FIG. 4A illustrates a schematic diagram of an example bundle of resources in a slot for a CG or SPS configuration in accordance with some example embodiments of the present disclosure. The signaling may indicate multiple SLIVs in a slot (i.e. SLIV #1, #2, #3) . Assuming the window is 2 slots, then the 6 resource in 2 slots are bundled, as shown in FIG. 4A.
[0111] FIG. 4B illustrates a schematic diagram of an example bundle of resources in multiple slots for a CG or SPS configuration in accordance with some example embodiments of the present disclosure. The signaling may indicate SLIV #1 in a first slot, and indicate 2 SLIVs, SLIV #2 and #3, in the second slot. Assuming the time window is 2 slots, then the 3 resource in 2 slots are bundled, as shown in FIG. 4B.
[0112] After the bundled resources are determined, the UE 201 may transmit a bitmap in UCI on CG PUSCH to indicate which resource in a second time domain window is unused. One bit of the bitmap may corresponds to one bundle of resources. In some embodiments, the bit indicates unused if all the resources in the bundle is unused. For example, if three resources included in the bundle, and if all the resources are unused, the bit may indicate unused; otherwise, the bit indicates not unused. In some embodiments, the bits for different resource bundle may be in the order of index of the bundle in the bitmap. For example, there could be 4 bundles of resources in the second time window, and there could be 4 bits and each bit is used to indicate whether each of the resource bundle is unused or not. The order of the bits may be in increasing order of the bundle indexes.
[0113] According to some embodiments discussed with reference to FIGS. 2 to 4B, bundle transmission of multiple PUSCH (s) and / or PDSCH (s) resources is implemented. In this way, transmission performances of the correlated flows can be guaranteed and improved jointly.
[0114] FIG. 5 illustrates an example of a device that is suitable for implementing some embodiments of the present disclosure. The device 500 may be an example of a UE 104 or network entity 102 as described herein.

The device 500 may include components for bi-directional communications including components for transmitting and receiving communications, such as a processor 502, a memory 504, a transceiver 506, and, optionally, an I / O controller 508. These components may be in electronic communication or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more interfaces (e.g., buses) .
[0115] The processor 502, the memory 504, the transceiver 506, or various combinations thereof or various components thereof may be examples of means for performing various aspects of the present disclosure as described herein. For example, the processor 502, the memory 504, the transceiver 506, or various combinations or components thereof may support a method for performing one or more of the operations described herein.
[0116] In some implementations, the processor 502, the memory 504, the transceiver 506, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry) .

In some implementations, the processor 502 and the memory 504 coupled with the processor 502 may be configured to perform one or more of the functions described herein (e.g., executing, by the processor 502, instructions stored in the memory 504) .
[0117] For example, the processor 502 may support wireless communication at the device 500 in accordance with examples as disclosed herein. The device 500 may be an example of a UE 104. In this case, the processor 502 may be configured to operable to support means for receiving, from a base station, one or more configured grant (CG) configurations for physical uplink shared channel (PUSCH) transmission and one or more semi-persistent scheduling (SPS) configurations for physical downlink shared channel (PUSCH) reception; means for determining a bundle of resources for PUSCH transmission and / or for SPS PDSCH reception; and means for performing the CG PUSCH transmission and / or the SPS PDSCH reception in the bundle of resources.
[0118] The device 500 may be an example of a network entity 102, e.g. a base station. In this case, the processor 502 may be configured to operable to support means for transmitting, to a user equipment (UE) , one or more configured grant (CG) configurations for physical uplink shared channel (PUSCH) reception and one or more semi-persistent scheduling (SPS) configurations for physical downlink shared channel (PUSCH) transmission; means for determining a bundle of resources for PUSCH reception and / or for SPS PDSCH transmission; and means for performing the CG PUSCH reception and / or the SPS PDSCH transmission in the bundle of resources.
[0119] The processor 502 may include an intelligent hardware device (e.g., a general-purpose processor, a DSP, a CPU, a microcontroller, an ASIC, an FPGA, a programmable logic device, a discrete gate or transistor logic component, a discrete hardware component, or any combination thereof) . In some implementations, the processor 502 may be configured to operate a memory array using a memory controller. In some other implementations, a memory controller may be integrated into the processor 502. The processor 502 may be configured to execute computer-readable instructions stored in a memory (e.g., the memory 504) to cause the device 500 to perform various functions of the present disclosure.
[0120] The memory 504 may include random access memory (RAM) and read-only memory (ROM) . The memory 504 may store computer-readable, computer-executable code including instructions that, when executed by the processor 502 cause the device 500 to perform various functions described herein. The code may be stored in a non-transitory computer-readable medium such as system memory or another type of memory. In some implementations, the code may not be directly executable by the processor 502 but may cause a computer (e.g., when compiled and executed) to perform functions described herein. In some implementations, the memory 504 may include, among other things, a basic I / O system (BIOS) which may control basic hardware or software operation such as the interaction with peripheral components or devices.
[0121] The I / O controller 508 may manage input and output signals for the device 500. The I / O controller 508 may also manage peripherals not integrated into the device 500. In some implementations, the I / O controller 508 may represent a physical connection or port to an external peripheral. In some implementations, the I / O controller 508 may utilize an operating system such as or another known operating system. In some implementations, the I / O controller 508 may be implemented as part of a processor, such as the processor 506. In some implementations, a user may interact with the device 500 via the I / O controller 508 or via hardware components controlled by the I / O controller 508.
[0122] In some implementations, the device 500 may include a single antenna 510. However, in some other implementations, the device 500 may have more than one antenna 510 (i.e., multiple antennas) , including multiple antenna panels or antenna arrays, which may be capable of concurrently transmitting or receiving multiple wireless transmissions. The transceiver 506 may communicate bi-directionally, via the one or more antennas 510, wired, or wireless links as described herein. For example, the transceiver 506 may represent a wireless transceiver and may communicate bi-directionally with another wireless transceiver. The transceiver 506 may also include a modem to modulate the packets, to provide the modulated packets to one or more antennas 510 for transmission, and to demodulate packets received from the one or more antennas 510. The transceiver 506 may include one or more transmit chains, one or more receive chains, or a combination thereof.
