[0001] This patent application claims the benefit of U.S. patent application Ser. No. 17 / 150,876 by XU et al., entitled "UPLINK RESOURCE SHARING FOR SIDELINK DEVICES," filed Jan. 15, 2021, which is assigned to the assignee of the present application and expressly incorporated herein by reference.

[0002] The following relates to wireless communications, including uplink resource sharing for sidelink devices. [Background technology]

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasts. These systems may be capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth-generation (4G) systems, such as Long Term Evolution (LTE), LTE-Advanced (LTE-A), or LTE-A Pro systems, and fifth-generation (5G) systems, sometimes referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communication system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, sometimes known as user equipment (UE).

[0004] Some UEs may enter an idle mode to conserve power, where entering the idle mode may include terminating the connection with the base station. However, in some cases, the UE may occasionally generate and transmit uplink data to the base station while in the idle mode. Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatuses that support uplink resource sharing for sidelink devices. Generally, the described techniques provide for allocating group-based configured uplink resources for idle mode uplink transmissions. User equipment (UE) may be grouped geographically and / or functionally and may have sidelink communication among themselves. In some scenarios, a group of UEs may enter idle mode, and in idle mode, UEs of the group may occasionally transmit uplink data to a base station. One or more configured uplink resources may be allocated (e.g., by a base station) to a group of clustered UEs for idle mode uplink transmissions. The base station may be aware of the group (e.g., based on signaling from UEs of the group) and may allocate one or more configured uplink resources to the group. The group of UEs may determine which UEs (e.g., of the group) may use the allocated resources at which times. Based on the determination, one or more UEs of the group may transmit uplink messages to the base station using the configured uplink resources assigned to the group.

[0006] A method for wireless communication in a first UE is described. The method may include: transmitting, to a base station, an indication of a UE group including a set of a plurality of sidelink UEs; receiving a group resource allocation message indicating an uplink group resource occasion to be allocated to at least one sidelink UE of the set of a plurality of sidelink UEs for idle mode uplink transmission; and transmitting an uplink message to the base station in idle mode during the uplink group resource occasion based on receiving the group resource allocation message.

The code may include instructions executable by a processor to: send, to a base station, an indication of a UE group including a set of a plurality of sidelink UEs; receive, based on the receiving group resource allocation message, an uplink group resource occasion to be allocated to at least one sidelink UE of the set of a plurality of sidelink UEs for idle mode uplink transmission; and transmit, to the base station in idle mode during the uplink group resource occasion, an uplink message.

[0053]

[0066] An idle mode user equipment (UE) may be configured with uplink resources (e.g., pre-configured uplink resources) for the UE to transmit uplink data to a base station without a radio resource control (RRC) connection to the network (e.g., without re-establishing a connection with the base station). When using the configured uplink resources for idle mode uplink transmission, overhead for connection establishment and / or uplink synchronization may be avoided. The configured uplink resources may repeat in time (e.g., may include multiple transmission occasions).

[0054]

[0067] The configured uplink resources may be configured for each UE, such that in a network with N idle mode UEs, N resources may be configured separately for each idle mode UE. In some cases, in idle mode, the UE may generate uplink data less frequently than the repetition of the configured uplink resources and thus leave some configured uplink resource occasions unused (e.g., during time periods or occasions when the UE may not generate uplink data for transmission to the base station). The unused resources may contribute to increased resource overhead and reduced resource usage. In some cases, the UE may additionally or alternatively generate more uplink data than can be transmitted via one configured uplink resource occasion. In such a case, the UE may transmit a portion of the uplink data in a first configured uplink resource occasion and a portion in a second configured uplink resource occasion (e.g., in a time period after the first configured uplink resource occasion), which may increase the transmission latency (e.g., the latency between the first and second configured uplink resource occasions).

[0055]

[0068] The present disclosure provides techniques for increasing resource usage, reducing resource overhead, and reducing communication latency, for example, based on group-based configured uplink resources. UEs in a group may be geographically and / or functionally clustered and may have sidelink communication among themselves. A group of UEs may enter an idle mode, in which UEs in the group may occasionally transmit uplink data to a base station (e.g., may have limited communication with the network based on being in an inactive or idle mode). Thus, UEs in the group may use configured uplink resources for uplink data transmission. One or more configured uplink resources may be allocated (e.g., by a base station) to a group of clustered UEs. The base station may be aware of the group (e.g., based on signaling from UEs in the group) and may allocate one or more configured uplink resources to the group. The group of UEs may determine which UEs (e.g., of the group) may use the allocated resources at which times.

[0056]

[0069] One or more UEs of the group may transmit uplink messages to the base station using the configured uplink resources assigned to the group (e.g., based on the group determining when and which UEs may use the configured uplink resources). The base station, in response to receiving the uplink message via the configured uplink resources, may transmit a response to the uplink message to one or more of the UEs of the group. Allocating configured uplink resources on a group basis may increase flexibility for allocating configured uplink resources to UEs 115 of the group, which may increase resource usage and reduce overhead. In some cases, a group configured uplink resource may include more resources than configured uplink resources for a single UE 115, which may reduce communication latency (e.g., by supporting transmission of uplink data in a single, larger configured uplink resource).

[0057]

[0070] Aspects of the present disclosure are initially described in the context of a wireless communication system and are further illustrated by and described with reference to process flows, apparatus diagrams, system diagrams, and flowcharts relating to uplink resource sharing for sidelink devices.

[0058]

[0071] 1 illustrates an example of a wireless communication system 100 according to an aspect of the present disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, communications using low-cost and low-complexity devices, or any combination thereof.

[0059]

[0072] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100 and may be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.

[0060]

[0073] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be fixed, mobile, or both at different times. The UEs 115 may be devices of different forms or with different capabilities. Some example UEs 115 are shown in FIG. 1. The UEs 115 described herein may be able to communicate with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), as shown in FIG. 1.

[0061]

[0074] The base stations 105 may communicate with the core network 130, with each other, or both. For example, the base stations 105 may interface with the core network 130 through one or more backhaul links 120 (e.g., via an S1, N2, N3, or other interface). The base stations 105 may communicate with each other over the backhaul links 120 (e.g., via an X2, Xn, or other interface) either directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130), or both. In some examples, the backhaul links 120 may be or include one or more wireless links.

[0062]

[0075] One or more of the base stations 105 described herein may include or be referred to by those skilled in the art as a base transceiver station, radio base station, access point, radio transceiver, Node B, eNode B (eNB), Next Generation Node B or GigaNode B (any of which may be referred to as gNB), Home Node B, Home eNode B, or other suitable terminology.

[0063]

[0076] The UE 115 may include or be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where a “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. The UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine-type communication (MTC) device, among other examples, which may be implemented in various objects, such as an appliance, a vehicle, a meter, or the like, among other examples.

[0064]

[0077] The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may act as relays at times, as shown in FIG. 1, as well as base stations 105 and network equipment, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples.

[0065]

[0078] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term “carrier” may refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier used for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) operated according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0066]

[0079] A signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing an MCM technique, a resource element may consist of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and the subcarrier spacing have an inverse relationship. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Thus, the more resource elements and the higher the order of the modulation scheme received by the UE 115, the higher the data rate for the UE 115 may be. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.

[0067]

[0080] The time interval for the base station 105 or the UE 115 may be, for example, T s =1 / (Δf max N f ) seconds, where Δf max may represent the maximum supported subcarrier spacing, and N f may represent the maximum supported discrete Fourier transform (DFT) size. The communication resource time intervals may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0068]

[0081] Each frame may include multiple consecutively numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into several slots. Alternatively, each frame may include a variable number of slots, and the number of slots may depend on the subcarrier spacing. Each slot may include several symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). In some wireless communications systems 100, a slot may be further divided into multiple minislots containing one or more symbols. Excluding the cyclic prefix, each symbol period may include one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the frequency operating band.

[0069]

[0082] A subframe, slot, minislot, or symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0070]

[0083] Physical channels may be multiplexed on carriers according to various techniques. Physical control channels and physical data channels may be multiplexed on downlink carriers using, for example, one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by several symbol periods and may span the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESET) may be configured for a set of UEs 115. For example, one or more of the UEs 115 may monitor or search the control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates at one or more aggregation levels configured in a cascaded manner. The aggregation level for the control channel candidates may refer to several control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for sending control information to multiple UEs 115 and a UE-specific search space set for sending control information to a specific UE 115.

[0071]

[0084] In some examples, the base stations 105 are mobile and may therefore provide communication coverage to moving geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include a heterogeneous network in which different types of base stations 105 provide coverage to various geographic coverage areas 110, for example, using the same or different radio access technologies.

[0072]

[0085] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that enable devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that incorporate sensors or meters to measure or capture information and relay such information to a central server or application program that utilizes the information or presents the information to a human interacting with the application program. Some UEs 115 may be designed to collect information or enable automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security detection, physical access control, and transaction-based business billing.

[0073]

[0086] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be implemented at a reduced peak rate. Other power-saving techniques for UEs 115 include entering a power-saving deep sleep mode when not engaged in active communication, operating on a limited bandwidth (e.g., pursuant to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or outside of the carrier.

[0074]

[0087] The wireless communication system 100 may be configured to support ultra-reliable or low-latency communications, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communications (URLLC) or mission-critical communications. The UE 115 may be designed to support ultra-reliable, low-latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communications may include private or group communications and may be supported by one or more mission-critical services, such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include service prioritization, and the mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0075]

[0088] In some examples, the UE 115 may also be able to communicate directly with other UEs 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication occurs between UEs 115 without the involvement of the base station 105.

[0076]

[0089] In some systems, the D2D communication link 135 may be an example of a communication channel, such as a sidelink communication channel, between vehicles (e.g., UE 115). In some examples, vehicles may communicate using vehicle-to-anything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination thereof. Vehicles may signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information relevant to the V2X system. In some examples, vehicles in a V2X system may communicate with roadside infrastructure, such as roadside units, or a network via one or more network nodes (e.g., base stations 105) using vehicle-to-network (V2N) communication, or both.

[0077]

[0090] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) that may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnections to external networks. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management, for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be forwarded through the user plane entity, which may provide IP address allocation and other functions. The user plane entities may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, intranet(s), IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0078]

[0091] Some of the network devices, such as the base station 105, may include sub-components, such as an access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with the UE 115 through one or more other access network transmitting entities 145, which may be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP). Each access network transmitting entity 145 may include one or more antenna panels. In some configurations, various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or integrated into a single network device (e.g., the base station 105).

[0079]

[0092] The wireless communication system 100 may typically operate using one or more frequency bands in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally, the 300 MHz to 3 GHz region is known as the ultra-high frequency (UHF) region or decimeter band because wavelengths range from approximately 1 decimeter to 1 meter in length. Although UHF waves may be blocked or redirected by buildings and environmental features, the waves may penetrate structures sufficiently for a macrocell to provide service to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0080]

[0093] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ license-assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices such as the base station 105 and the UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed band may be based on a carrier aggregation configuration with component carriers operating in a licensed band (e.g., LAA). Operation in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0081]

[0094] The base station 105 or the UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or the UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located in an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the base station 105 may be located in various geographic locations. The base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 can use to support beamforming of communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted through the antenna ports.

[0082]

[0095] Beamforming, sometimes referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference and others experience destructive interference. Adjusting signals communicated via antenna elements may include the transmitting or receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. The adjustment associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., relative to the antenna array of the transmitting or receiving device or to some other orientation).

[0083]

[0096] A group of UEs 115 may be geographically and / or functionally clustered and may have sidelink communication among themselves. A group of UEs 115 may enter an idle mode, where a UE 115 of the group may occasionally transmit uplink data to the base station 105 (e.g., may have limited communication with the network based on entering an inactive or idle mode). A base station 105 may allocate one or more configured uplink resources to a group of clustered UEs 115. The base station 105 may be aware of the group based on signaling from the UEs 115 of the group. A group of UEs 115 may determine which UEs 115 (e.g., of the group) may use the allocated resources and at which times. One or more UEs 115 of the group may transmit uplink messages to the base station 105 using the configured uplink resources assigned to the group (e.g., based on the group determining when and which UEs may use the configured uplink resources).

[0084]

[0097] 2 illustrates an example of a wireless communication system 200 according to aspects of the present disclosure. In some examples, the wireless communication system 200 may implement some aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a base station 105-a and UEs 115-b, 115-c, 115-d, 115-e, 115-f, 115-g, and 115-h, which may represent examples of the base station 105 and the UEs 115, respectively, described with reference to FIG. 1. In some cases, the UEs 115-a, 115-b, 115-c, 115-d, 115-e, 115-f, 115g, and 115-h may represent UEs 115 operating in an idle mode with the base station 105-a.

[0085]

[0098] The idle mode UE 115 may, for example, previously operate in a connected mode with the base station 105-a and may receive a message (e.g., an RRCRelease message) to switch the UE 115 to an idle mode or an inactive mode. To re-enter the connected mode, the UE 115 may re-establish a connection with the base station 105-a, for example, via a random access procedure. The idle mode UE (e.g., any of the idle mode UEs 115) may be configured with uplink resources (e.g., pre-configured uplink resources) for the UE 115 to transmit uplink data to the base station 105-a without connecting to a network (e.g., without re-establishing a connection with the base station 105-a). The UE 115 may use the configured uplink resources, for example, to report sensed data (e.g., small-sized sensed data) to the network (e.g., may sporadically report sensed data to the network).

[0086]

[0099] When using configured uplink resources for idle or inactive mode uplink transmissions, overhead for connection establishment and / or uplink synchronization may be avoided. For example, the configured uplink resources may be applicable to a fixed or low mobility UE 115 and may remain valid if timing alignment verification rules are satisfied, thus avoiding overhead for connection establishment and / or uplink synchronization. For example, if an idle mode UE 115 has a low amount of movement, uplink timing may be roughly synchronized. Configuration parameters for the configured uplink resources may be provided by the network, such as via an RRCRelease message to the idle or inactive mode UE 115. The configured uplink resources may repeat in time (e.g., may include multiple transmission occasions) for the UE 115 to transmit uplink data over time (e.g., periodically).

[0087]

[0100] The base station 105-a may transmit a response to an uplink transmission received on the configured uplink resources from the idle or inactive mode UE 115. The response may include an indication of whether the uplink transmission was successfully decoded, a timing advance command to adjust the uplink timing for the UE 115 (e.g., to synchronize with the base station 105-a), an adjustment of the configured uplink resource configuration (e.g., an instruction to use a modulation coding scheme (MCS) or transmit power for a subsequent uplink transmission), an instruction for the UE 115 to stop using the configured uplink resources, or any combination thereof.

[0088]

[0101] The configured uplink resources may be configured for each UE 115, such that in a network with N idle mode UEs 115, the N resources may be configured separately for each of the UEs 115. In some cases, in idle mode, the UE 115 may generate uplink data for transmission to the base station 105-a less frequently than the repetition of the configured uplink resources and thus leave some configured uplink resource occasions unused (e.g., during time periods or occasions when the UE 115 may not generate uplink data for transmission to the base station 105-a). The unused resources may contribute to increased resource overhead and reduced resource usage. In some cases, the UE 115 may additionally or alternatively generate more uplink data (e.g., during a time period) than is possible to transmit via one configured uplink resource occasion. In such a case, UE 115 may transmit a portion of the uplink data in a first configured uplink resource occasion and a portion in a second configured uplink resource occasion (e.g., in a time period after the first configured uplink resource), which may increase transmission latency (e.g., the latency between the first configured uplink resource occasion and the second configured uplink resource occasion).

[0089]

[0102] The present disclosure provides techniques for increasing resource usage, reducing resource overhead, and lowering communication latency, for example, based on group-based configured uplink resource configuration. The UEs 115 of a group 205 may be geographically and / or functionally clustered and may have sidelink communications among themselves. In some cases, a UE 115 may be included in multiple groups 205. A group 205 of UEs 115 may operate in an idle mode that may limit communication with the network (e.g., over an interface between the UE 115 and the base station 105-a, such as a UMTS Terrestrial Radio Access Network (UTRAN)-to-UE (Uu) interface) and may be in an inactive or idle mode most of the time. Thus, the UEs 115 of a group 205 may use the configured uplink resources for uplink data transmission.

[0090]

[0103] One or more configured uplink resources may be allocated (e.g., by the base station 105-a) to a group 205 of clustered UEs 115. In some cases, the amount of resources allocated to a group may be greater than the amount of resources allocated to a single UE 115. The base station 105-a may be aware of the group 205 (e.g., based on signaling from the UEs 115 of the group), e.g., may be aware of a group ID of the group 205 and at least one UE 115 of the group. The group 205 may determine when and which UEs 115 (e.g., of the group 205) may use the allocated resources.

[0091]

[0104] In one example, a UE 115-a (e.g., an enhanced mobile broadband (eMBB) UE 115 such as a cellphone) and several wearable devices (e.g., reduced-capability UEs 115-b, 115-c, and 115-d) carried by the same person may form a cluster or group 205-a. The wearable devices may be clustered together with the UE 115-a and may use the UE 115-a as a central control (e.g., based on the wearable devices being lower-tier or reduced-capability tier UEs 115). In another example, a group of wireless sensors (e.g., UEs 115-e, 115-f, 115-g, and 115-h) may form a cluster or group 205-b. The wireless sensors may be clustered with sidelink communication among themselves.

[0092]

[0105] One or more UEs 115 in group 205-a or 205-b may transmit uplink messages to base station 105-a using the configured uplink resources assigned to the respective group 205 (e.g., based on the group 205 determining when and which UEs 115 may use the configured uplink resources). In response to receiving the uplink message via the configured uplink resources, base station 105-a may transmit a response to the uplink message to one or more of the UEs 115 in the respective group 205.

[0093]

[0106] 3 illustrates an example of a wireless communication system 300 according to aspects of the present disclosure. In some examples, the wireless communication system 300 may implement some aspects of the wireless communication systems 100 or 200. For example, the wireless communication system 300 may include a base station 105-b and UEs 115-i, 115-j, 115-k, and 115-l, which may represent examples of the base station 105 and UEs 115, respectively, described with reference to FIG. 2. As described with reference to FIG. 2, the UEs 115-i, 115-j, 115-k, and 115-l may form a group 305 of sidelink UEs 115, where the group 305 may be assigned group-configured uplink resources for idle mode uplink transmissions to the base station 105-b.

[0094]

[0107] Configured uplink resources (e.g., pre-configured uplink resources) may be configured for a group 305 of clustered UEs 115. In a first example, the same configured uplink resources may be configured for one UE 115, or a subset of the UEs 115, in the group 305. The configured uplink resource configuration may be propagated by the UE 115 or subset of the UEs 115 to other UEs 115 in the group 305. For example, UE 115-i (e.g., among other UEs 115 of the group 305) may receive the configured uplink resource configuration (e.g., from base station 105-b) and share the configuration for other UEs 115 in the group 305, such as UEs 115-j, 115-k, and 115-l (e.g., among other UEs 115).

[0095]

[0108] In a second example, the same configured uplink resources may be configured for all UEs 115 of a group 305 (e.g., base station 105-b may send a configuration to each UE 115 of the group 305). In such a case, the network may indicate in the configured uplink resource configuration that the resources are group-based resources by including a group ID of the group 305 (e.g., in a field of a message).

[0096]

[0109] Allocation of configured uplink resource(s) per UE cluster (e.g., UE group-based resource allocation) may simplify configured uplink resource management at the base station 105-b. Because the UEs 115 in a group 305 may be geographically and / or logically clustered, the UEs 115 may more dynamically adjust each UE's 115's use of the configured uplink resource(s). Furthermore, group-based resource allocation may avoid resource fragmentation (e.g., which may occur with per-UE resource allocation when the number of UEs 115 is large). In some cases, the total number of resources for a group 305 of UEs 115 may be reduced (e.g., this may reduce total overhead), and the instantaneous or quantity of resources that can be used per UE 115 (e.g., maximum amount of resources) may be increased.

[0097]

[0110] 4 illustrates an example of a process flow 400 according to aspects of the present disclosure. In some examples, the process flow 400 may implement or be implemented by some aspects of the wireless communication system 100 or 200. In some examples, the process flow 400 may implement or be implemented by some aspects of the wireless communication system 300. The process flow 400 may be implemented by a base station 105-c and a UE 115-m, which may represent examples of the base station 105 and the UE 115, respectively, described with reference to FIGS. 1-3. The UE 115-m may represent a UE 115 in a group of sidelink UEs 115, where the group may be assigned group-configured uplink resources for idle mode uplink transmissions to the base station 105-c.

[0098]

[0111] In the following description of process flow 400, operations may be performed in a different order than shown, or the operations performed by UE 115-m and base station 105-c may be performed in a different order or at different times. Also, for example, certain operations may be omitted from process flow 400, or other operations may be added to process flow 400. Although UE 115-m and base station 105-c are shown performing the operations of process flow 400, some aspects of some operations may also be performed by one or more other wireless devices.

[0099]

[0112] The network (e.g., base station 105-c) may signal that a single UE 115-m (e.g., among other UEs 115 in a group) configures group-based configured uplink resources. In a first example, the network (e.g., base station 105-c) may configure the group-configured uplink resources in an RRCRelease message to the UE 115-m when the UE 115-m exits connected mode. For example, at 510, the base station 105-c may send the group-configured uplink resource configuration to the UE 115-m via an RRCRelease message (e.g., or other message related to exiting connected mode). The RRCRelease message may follow a procedure (e.g., a defined or conventional procedure) for providing the configuration to the UE 115-m.

[0100]

[0113] In a second example, the network (e.g., base station 105-c) may configure group-configured uplink resources in a different RRC message (e.g., an RRC message other than an RRCRelease message) to connected mode UEs 115 in a group of UEs 115. For example, at 505, base station 105-c may send a group-configured uplink resource configuration to UE 115-m when UE 115-m operates in connected mode. In such a case, connected mode UE 115 (e.g., UE 115-m) may represent a controller UE 115 for the group.

[0101]

[0114] In any of the examples described herein, the network may configure group-configured uplink resources for one UE 115 or multiple UEs 115 in a group (e.g., a subset or all of the UEs 115), as described with reference to FIG. 3.

[0102]

[0115] In some cases, multiple configured uplink resources (e.g., multiple, repeatedly configured uplink resources) may be allocated to a group of UEs 115. When multiple configured uplink resources are allocated, a UE 115 (e.g., UE 115-m) in the group may be assigned (e.g., allocated) two or more configured uplink resources for communication with the base station 105-c (e.g., based on the amount of data to be transmitted by the UE 115). A UE 115 (e.g., a reduced capability UE) may use multiple resources to repeat transmission of an uplink message, e.g., to compensate for gain loss due to a reduced number or size of antennas. For example, UE 115-m may repeat transmission of uplink data at 515 and at 525 (e.g., the base station may transmit respective responses to UE 115-m at 520 and 530).

[0103]

[0116] 5 illustrates an example of a wireless communication system 500 according to aspects of the present disclosure. In some examples, the wireless communication system 500 may implement some aspects of the wireless communication systems 100 or 200. In some examples, the wireless communication system 500 may implement or be implemented by some aspects of the wireless communication system 300 or the process flow 400. The wireless communication system 500 may include a base station 105-d and UEs 115-n, 115-o, 115-p, 115-q, and 115-r, which may represent examples of the base station 105 and the UEs 115, respectively, described with reference to FIGS. 1-4. The UEs 115 may be included in groups 505 of sidelink UEs 115, where each group 505 may be assigned group-configured uplink resources for idle mode uplink transmissions to the base station 105-d.

[0104]

[0117] To avoid collisions between UEs 115, each group-configured uplink resource may be used by a single respective UE 115 in one occasion, unless relaying (e.g., relaying the same information or data) applies to improve uplink transmission to base station 105-d. In a first example, group-configured uplink resources allocated to a group of UEs 115 may be used by one UE 115 within a group-configured uplink resource occasion to transmit uplink data to the network. For example, UE 115-n may use a group-configured uplink resource occasion allocated to group 505-a to transmit uplink data to base station 105-d. The first example may also include a case where one UE 115 relays uplink data originating from another UE 115 in group 505. For example, UE 115-o may use a group-configured uplink resource occasion allocated to group 505-b to transmit uplink data to base station 105-d, where the uplink data may be relayed from UE 115-p to UE 115-o.

[0105]

[0118] In a second example, group-configured uplink resources allocated to a group 505 of UEs 115 may be used by multiple UEs 115 within a group-configured uplink resource occasion to transmit the same uplink data to the network. For example, UE 115-q and UE 115-r may use a group-configured uplink resource occasion allocated to group 505-c to transmit uplink data to base station 105-d, where the uplink data may be relayed from UE 115-r to UE 115-q (e.g., in the case of overlapping or simultaneous transmissions). Transmissions of uplink data by UEs 115-q and 115-r may at least partially overlap in time, frequency, or both (e.g., overlap within a group-configured uplink resource occasion). The second example may represent spatial repetition, for example, when a UE 115 (e.g., a reduced-capability UE 115) may have limited uplink transmit power.

[0106]

[0119] In any of the examples described herein, relaying may be initiated by (e.g., requested by) a first UE 115 originating uplink data, or may be initiated by a second UE 115 (e.g., in the same group 505) providing relay services to the first UE 115. A transmitting UE 115 (e.g., UE 115-n, 115-o, 115-q, or 115-r) may include identification information (e.g., an identifier (ID)) in an uplink transmission to indicate the UE 115 that generated (e.g., originally generated) the uplink data.

[0107]

[0120] As described herein, relaying uplink transmissions to the base station 105-d may improve uplink coverage of the network and may reduce power consumption (e.g., conserve power) at the UE 115 (e.g., reduced-capacity UE 115). Accordingly, the UEs 115 in the group 505 may transmit uplink data on group-configured uplink resources, according to one or more examples. In a first example, the uplink data may be transmitted directly to the base station 105-d on the group-configured uplink resources (e.g., in a group-configured uplink resource occasion). In a second example, the uplink data may be transmitted on the group-configured uplink resources (e.g., in a group-configured uplink resource occasion) to both the base station 105-d and one or more relay UEs 115 in the group 505. The one or more relay UEs 115 may further transmit uplink data to the base station 105-d on a later group-configured uplink resource occasion. For example, UE 115-r may transmit the same uplink data to base station 105-d and UE 115-q (e.g., for future relay) in the same group-configured uplink resource occasion, and UE 115-q may then relay the uplink data to base station 105-d in a subsequent group-configured uplink resource occasion.

[0108]

[0121] In a third example, UE 115 may transmit uplink data to one or more relay UEs 115 (e.g., via the sidelink) before a group-configured uplink resource occasion, and both UE 115 and one or more relay UEs 115 may transmit the same uplink data (e.g., to base station 105-d) in the group-configured uplink resource occasion. For example, UE 115-r may alternatively transmit uplink data to UE 115-q before the group-configured uplink resource occasion, and both UE 115-q and UE 115-r may transmit uplink data to base station 105-d in group-configured uplink resource occasions (e.g., that at least partially overlap in time, frequency, or both). Transmitting uplink data in the same group-configured uplink resource occasion may increase the total transmit power for the uplink data. Doing so may increase communication quality (e.g., among other metrics) when, for example, a group of UEs 115 are at a cell edge or otherwise located a certain distance away from the base station 105-d.

[0109]

[0122] When group-configured uplink resources are shared by a group of UEs 115, the group of UEs 115 may decide which UEs 115 may use the group-configured uplink resources (e.g., may use group-configured uplink resource occasions) and when. This decision may be made in a centralized manner, such as when a controller UE 115 is present in the group 505, or may be made based on requests from each UE 115 to the rest of the group.

[0110]

[0123] In a first example, use of group-configured uplink resources may be allocated by a controller UE 115 in a group 505. For example, in a group 505 with one eMBB UE 115 and multiple reduced capability UEs 115 (e.g., group 505-b), the eMBB UE 115 may be the controller UE 115. Such a group 505 may be represented by group 505-b, where UE 115-o may represent the eMBB UE 115 and other UEs 115 (e.g., including UE 115-p) may represent reduced capability UEs 115. The controller UE 115 may either determine a pattern for different UEs 115 to use the group-configured uplink resources or allocate the group-configured uplink resources to the UE 115 based on a request (e.g., a broadcast request) from that UE 115. For example, UE 115-p may send a request to UE 115-o, and UE 115-o may allocate group-configured uplink resource occasions to UE 115-p based on the request. Additionally or alternatively, UE 115-o may independently allocate group-configured uplink resource occasions to other UEs 115 of group 505-b (e.g., including UE 115-p).

[0111]

[0124] In a second example, the UE 115 may reserve group-configured uplink resources (e.g., one or more occasions) for a duration. For example, the UE 115 may transmit (e.g., broadcast to other UEs 115 of the group 505) a request to reserve the group-configured uplink resources (e.g., to reserve one or more occasions) in sidelink control information (SCI). Once the group-configured uplink resources are reserved by the UE 115, the group-configured uplink resources (e.g., the one or more occasions reserved by the UE 115) may not be reserved (e.g., may be restricted from being reserved) by another UE 115. The duration (e.g., one or more occasions) for which the group-configured uplink resources may be consecutively reserved by the UE 115 may have a limit or threshold (e.g., a threshold amount of time or a threshold number of occasions). The limit may, for example, be stored in the UE 115 or signaled by the base station 105-d and may restrict the UE 115 from reserving grouped uplink resources for a duration greater than the limit.

[0112]

[0125] In any of the examples described herein, when multiple group-configured uplink resources are configured for a group 505, one UE 115 may be allocated or reserve two or more configured uplink resources at a time (e.g., may be allocated or reserve a respective occasion for multiple of the two or more group-configured uplink resources). For example, the UE 115 may be allocated multiple group-configured uplink resources by a controller UE 115, or the UE 115 may transmit an SCI reserving multiple group-configured uplink resources. Because all UEs 115 in a group 505 may not necessarily attempt to use the group-configured uplink resources simultaneously, the actual available resources (e.g., available amount of resources) for each UE 115 at a time may be greater than the average amount of resources per UE 115 configured for the group 505.

[0113]

[0126] 6 illustrates an example of a wireless communication system 600 according to aspects of the present disclosure. In some examples, the wireless communication system 600 may implement some aspects of the wireless communication systems 100 or 200. In some examples, the wireless communication system 600 may implement or be implemented by some aspects of the wireless communication systems 300 or 500 or the process flow 400. The wireless communication system 600 may include a base station 105-e and UEs 115-s, 115-t, 115-u, and 115-v, which may represent examples of the base station 105 and the UEs 115, respectively, described with reference to FIGS. 1-5. The UE 115 may be included in a group 605 of sidelink UEs 115, where the group 605 may be assigned group-configured uplink resources for idle mode uplink transmissions to the base station 105-e.

[0114]

[0127] 2, a base station 105-e may transmit a configured uplink resource response (e.g., response 620) when the base station 105-e receives an uplink transmission (e.g., uplink data 610) on allocated resources (e.g., group configured uplink resources). For example, the base station 105-e may transmit a configured uplink resource response when it receives an uplink transmission from any UE 115 of the group 605 on allocated group configured uplink resources. In a first example, a UE 115 (e.g., UE 115-s) transmitting uplink data 610 in a group configured uplink resource occasion may receive the configured uplink resource response (e.g., from the base station 105-e) in a configured response window 615 (e.g., a configured uplink resource response window).

[0115]

[0128] In a second example, the controller UE 115 may receive a configured uplink resource response (e.g., in the response window 615), where the controller UE 115 (e.g., a control node) may be the same UE 115 or a different UE 115 from the UE 115 transmitting the uplink data 610. For example, UE 115-s may represent a cellphone (e.g., controller UE 115) that receives the configured uplink resource response for the wearables (e.g., UEs 115-t, 115-u, and 115-v) in the cluster or group 605. In such a case, UE 115-s may forward or relay the configured uplink resource response to one or more other UEs 115 of the group 605.

[0116]

[0129] In a third example, multiple UEs 115 may receive the configured uplink resource response. For example, as described with reference to FIG. 5, if multiple UEs 115 transmit uplink data 610 (e.g., for coverage extension), they may also receive the configured uplink resource response, which may improve downlink coverage (e.g., if extended downlink coverage may be needed). In one example, UE 115-s and UE 115-t (e.g., among other UEs 115) may both receive the configured uplink resource response (e.g., based on both UE 115-s and 115-t transmitting uplink data 610).

[0117]

[0130] If one or more UEs 115 detect a timing advance command or a group configured uplink resource configuration update in a configured uplink resource response, the one or more UEs 115 may propagate (e.g., relay, transmit) the information to other UEs 115 (e.g., one or more other UEs 115) in the group 605. From the next group configured uplink resource occasion, the UEs 115 in the group 605 may use the adjusted timing advance and / or group configured uplink resource configuration for uplink transmissions to the base station 105-e.

[0118]

[0131] FIG. 7 illustrates an example of a process flow 700 according to aspects of the present disclosure. In some examples, process flow 700 may implement or be implemented by some aspects of wireless communication systems 100 or 200. In some examples, process flow 700 may implement or be implemented by some aspects of wireless communication systems 300, 500, or 600, or process flow 400. Process flow 700 may be implemented by base station 105-f and UEs 115-w and 115-x, which may represent examples of base station 105 and UE 115, respectively, described with reference to FIGS. 1-6. UEs 115-w and 115-x may represent UEs 115 in a group of sidelink UEs 115, where the group may be assigned group-configured uplink resources for idle mode uplink transmissions to base station 105-f.

[0119]

[0132] In the following description of process flow 700, operations may be performed in a different order than shown, or the operations performed by UEs 115-w, 115-x and base station 105-f may be performed in a different order or at different times. Also, for example, certain operations may be omitted from process flow 700, or other operations may be added to process flow 700. Although UEs 115-w, 115-x, and base station 105-f are shown performing the operations of process flow 700, some aspects of some operations may also be performed by one or more other wireless devices.

[0120]

[0133] At 705, the UE 115-w may transmit to the base station 105-f an indication of a UE group that includes multiple sidelink UEs 115 (e.g., including UE 115-w and 115-x). For example, the UE 115-w may transmit the indication of the UE group based on forming or joining a UE group. In some cases, the UE 115-w may transmit the indication of the UE group based on entering or preparing to enter idle mode. For example, the UE 115-w may transmit the indication as a control message that includes a group ID of the group.

[0121]

[0134] At 710, the base station 105-f may transmit a group resource allocation message indicating uplink group resource occasions to be allocated to at least one sidelink UE 115 of the plurality of sidelink UEs 115 for idle mode uplink transmissions. The group resource allocation message may, for example, indicate single or multiple occasions of group-configured uplink resources (e.g., configured for at least one sidelink UE of a group of sidelink UEs 115). In some cases, the group resource allocation message may indicate a threshold (e.g., limit) number of consecutive uplink transmissions for which one UE 115 of the group may use the uplink group resource occasion. In some cases, the base station 105-f may indicate the threshold via another transmission (e.g., via configuration signaling).

[0122]

[0135] In some cases, the group resource allocation message may indicate an uplink group resource response occasion corresponding to the uplink group resource occasion. In some cases, the base station 105-f may indicate the uplink group resource response occasion via a separate transmission (e.g., via configuration signaling). In some cases, the UE 115-w (e.g., or another UE 115 of the group) may transmit a request for group resources for idle mode uplink transmission for the UE group, and the base station 105-f may transmit the group resource allocation message based on receiving the request for group resources. For example, the UE 115-w may transmit the request for group resources via the UE group indication or via a separate transmission to the base station 105-f.

[0123]

[0136] In some cases, base station 105-f may transmit a group resource allocation message to a subset of UEs 115 of the group (e.g., including UE 115-w), and the subset of UEs 115 (e.g., UE 115-w) may forward or transmit an indication of the group resource allocation to one or more other UEs 115 of the group (e.g., to UE 115-x). In some cases, base station 105-f may transmit a group resource allocation message to each UE 115 of the group.

[0124]

[0137] At 715, in some cases, UE 115-w and 115-x (e.g., among other UEs 115 of the group) may coordinate resource allocation for an uplink group resource occasion. In a first example, as described herein, controller UE 115 may coordinate resource allocation for a UE group. For example, UE 115-x may represent controller UE 115 and may allocate (e.g., send an allocation message indicating the allocation) an uplink group resource occasion to UE 115-w independently or based on a request from UE 115-w (e.g., an allocation request message requesting an uplink group resource occasion). In a second example, UE 115 of the group may transmit a sidelink control message (e.g., SCI) to reserve an uplink group resource occasion. For example, UE 115-w may detect that an uplink group resource occasion is not reserved (e.g., based on a previously received sidelink control message from another UE 115 of the group) and may transmit (e.g., broadcast) a sidelink control message to multiple UEs 115 of the group reserving the uplink group resource occasion.

[0125]

[0138] At 720, in some cases, UE 115-w and 115-x may perform relaying for uplink messages for transmission using the uplink group resource occasion. For example, UE 115-w may transmit uplink data for an uplink message for UE 115-x to transmit to base station 105-f to UE 115-x (e.g., along with the transmission of the uplink message from UE 115-w to base station 105-f). As described herein, UE 115-w may transmit the uplink data during the uplink group resource occasion (e.g., for a later transmission by UE 115-x) or may transmit the uplink data before the uplink group resource occasion (e.g., for transmission to base station 105-f during the uplink group resource occasion). In some cases, UE 115-x may transmit uplink data to UE 115-w for UE 115-w to transmit to base station 105-f during an uplink group resource occasion (e.g., where UE 115-x may not transmit uplink data to base station 105-f).

[0126]

[0139] At 725, UE 115-w may, in idle mode, transmit an uplink message (e.g., including uplink data) to base station 105-f during an uplink group resource occasion based on receiving the group resource allocation message (e.g., and based on performing coordinating and / or relaying resource allocation). In some cases, UE 115-x may also transmit a second uplink message (e.g., including uplink data) to base station 105-f. For example, UE 115-x may transmit the second uplink message in an uplink group resource occasion (e.g., that at least partially overlaps with the uplink message transmitted by UE 115-w, such as at least partially overlapping in time, frequency, or both) or in a second uplink group resource occasion after the uplink group resource occasion.

[0127]

[0140] At 730, in some cases, the base station 105-f may send to the UE 115-w a response to the uplink message in an uplink group resource response occasion corresponding to the uplink group resource occasion. In some cases, the response may include a timing advance command or an indication of adjustment for the uplink group resource occasion. In such a case, the UE 115-w may forward or transmit at 735 to one or more other UEs 115 of the group (e.g., to the UE 115-x) the timing advance command or indication of adjustment for the uplink group resource occasion. In some cases, if the uplink data of the uplink message originated at the UE 115-x (e.g., or if the UE 115-x also transmitted uplink data to the base station 105-f), the UE 115-w may forward or transmit at 735 an indication of response to the UE 115-x.

[0128]

[0141] 8 shows a block diagram 800 of a device 805 according to an aspect of the present disclosure. The device 805 may be an example of an aspect of a UE 115 described herein. The device 805 may include a receiver 810, a transmitter 815, and a communications manager 820. The device 805 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0129]

[0142] The receiver 810 may provide a means for receiving information such as packets, user data, control information, or any combination thereof, associated with various traffic channels (e.g., control channels, data channels, traffic channels related to uplink resource sharing for sidelink devices). The information may be passed to other components of the device 805. The receiver 810 may utilize a single antenna or a set of multiple antennas.

[0130]

[0143] The transmitter 815 may provide a means for transmitting signals generated by other components of the device 805. For example, the transmitter 815 may transmit information such as packets associated with various traffic channels (e.g., a control channel, a data channel, a traffic channel related to uplink resource sharing for sidelink devices), user data, control information, or any combination thereof. In some examples, the transmitter 815 may be co-located with the receiver 810 in a transceiver module. The transmitter 815 may utilize a single antenna or a set of multiple antennas.

[0131]

[0144] The communications manager 820, the receiver 810, the transmitter 815, or various combinations thereof or components thereof may be examples of means for implementing various aspects of uplink resource sharing for sidelink devices described herein. For example, the communications manager 820, the receiver 810, the transmitter 815, or various combinations thereof or components thereof may support a method for implementing one or more of the functions described herein.

[0132]

[0145] In some examples, the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be implemented in hardware (e.g., in communications management circuitry). The hardware may include a processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured as or otherwise supporting a means for performing the functions described in this disclosure. In some examples, the processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing, by the processor, instructions stored in the memory).

[0133]

[0146] Additionally or alternatively, in some examples, the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be implemented in code (e.g., as communications management software or firmware) executed by a processor. If implemented in code executed by a processor, the functionality of the communications manager 820, the receiver 810, the transmitter 815, or various combinations or components thereof may be performed by a general-purpose processor, a DSP, a central processing unit (CPU), an ASIC, an FPGA, or any combination thereof or other programmable logic device (e.g., configured as or otherwise supporting a means for performing the functions described in this disclosure).

[0134]

[0147] In some examples, the communications manager 820 may be configured to perform various operations (e.g., receiving, monitoring, transmitting) using or otherwise cooperating with the receiver 810, the transmitter 815, or both. For example, the communications manager 820 may be incorporated in combination with the receiver 810, the transmitter 815, or both to receive information from the receiver 810, send information to the transmitter 815, or receive information, transmit information, or perform various other operations described herein.

[0135]

[0148] The communications manager 820 may support wireless communications at a first UE according to examples disclosed herein. For example, the communications manager 820 may be configured with or otherwise support a means for transmitting, to a base station, an indication of a UE group including a set of a plurality of sidelink UEs. The communications manager 820 may be configured with or otherwise support a means for receiving a group resource allocation message indicating an uplink group resource occasion to be allocated to at least one sidelink UE of the set of a plurality of sidelink UEs for idle mode uplink transmission. The communications manager 820 may be configured with or otherwise support a means for transmitting an uplink message to the base station in idle mode during the uplink group resource occasion based on receiving the group resource allocation message.

[0136]

[0149] Among other examples herein, actions performed by the communications manager 820 may be implemented to realize one or more potential benefits. For example, the communications manager 820 may increase available battery power and communication quality at a wireless device (e.g., UE 115) by supporting the allocation and use of group-configured uplink resources. The increased communication quality may result in increased link performance and reduced overhead based on using group-configured uplink resources for idle mode transmissions. Thus, the communications manager 820 may conserve power and increase battery life at the wireless device (e.g., UE 115) by strategically increasing the quality of communications at the wireless device (e.g., UE 115).

[0137]

[0150] 9 shows a block diagram 900 of a device 905 according to an aspect of the present disclosure. The device 905 may be an example of an aspect of the device 805 or the UE 115 described herein. The device 905 may include a receiver 910, a transmitter 915, and a communications manager 920. The device 905 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0138]

[0151] The receiver 910 may provide a means for receiving information such as packets, user data, control information, or any combination thereof, associated with various traffic channels (e.g., control channels, data channels, traffic channels related to uplink resource sharing for sidelink devices). The information may be passed to other components of the device 905. The receiver 910 may utilize a single antenna or a set of multiple antennas.

[0139]

[0152] The transmitter 915 may provide a means for transmitting signals generated by other components of the device 905. For example, the transmitter 915 may transmit information such as packets associated with various traffic channels (e.g., a control channel, a data channel, an traffic channel related to uplink resource sharing for sidelink devices), user data, control information, or any combination thereof. In some examples, the transmitter 915 may be co-located with the receiver 910 in a transceiver module. The transmitter 915 may utilize a single antenna or a set of multiple antennas.

[0140]

[0153] The device 905, or various components thereof, may be an example of a means for implementing various aspects of uplink resource sharing for sidelink devices described herein. For example, the communications manager 920 may include a UE group indication component 925, a group resource allocation receiving component 930, an uplink transmission component 935, or any combination thereof. The communications manager 920 may be an example of an aspect of the communications manager 820 described herein.
