[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 705,997, filed July 24, 2020, entitled “CONFIGURED GRANT SIDELINK COMMUNICATION,” and U.S. Non-Provisional Patent Application No. 17 / 304,427, filed June 21, 2021, entitled “CONFIGURED GRANT SIDELINK COMMUNICATIONS,” which are expressly incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to wireless communication, and specifically to techniques and apparatus for configuring licensed sidelink communication. Background Technology

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmission power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include many base stations (BSs) that can support communication for many user equipments (UEs). UEs can communicate with BSs via downlinks and uplinks. A "downlink" (or "forward link") refers to the communication link from the BS to the UE, and an "uplink" (or "backlink") refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Head, Transmitter Receiver Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. NR, which can also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3 GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), using CP- OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain very useful. SUMMARY

[0026] Aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of, or combined with, any other aspect of the disclosure. In some aspects, the functionality described herein can be implemented in any quantity of aspects to achieve one or more of the advantages described herein. Additionally, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using, in addition to or in place of the subject matter explicitly disclosed, any of the aspects of the disclosure. It is understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of a claim.

[0027] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0028] It should be noted that while aspects can be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and / or a RAT subsequent to 5G (e.g., 6G).

[0029] Figure 1FIG. 1 is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 can be or include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 can include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 1 lOd) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and can also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), and / or the like. Each BS can provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0030] BSs can be referred to as macro BS, small cell, femto cell, and / or other types of BSs. A macro cell can cover a relatively large geographic area (e.g., 5 kilometers in radius) and can allow unrestricted access by UEs with service subscription. A small cell can cover a relatively small geographic area and can allow restricted access by UEs with service subscription. A femto cell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs with service subscription. Figure 1 In an example shown in FIG. 1, the BS 110a can be a macro BS for a macro cell 102a, the BS 110b can be a small cell for a small cell 102b, and BS 110c can be a femto cell for a femto cell 102c. A BS can support one or multiple (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” can be used interchangeably herein.

[0031] In some aspects, a cell can not necessarily be stationary, and the geographic area of the cell can move according to the location of a mobile BS. In some examples, the BSs can be interconnected to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as a direct physical connection or a virtual network, using any suitable transport network.

[0032] Wireless network 100 can also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1 In the example shown in FIG. 1, relay BS 1 lOd can be in communication with macro BS 110a and UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, a relay base station, a relay, or the like.

[0033] Wireless network 100 can be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs can have a high transmit power level (e.g., 5 to 40 Watts), whereas pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 Watts).

[0034] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can be

[0035] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device such as a smart watch, smart clothing, smart glasses, a smart wrist band, smart jewelry (e.g., a smart ring, a smart bracelet), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

[0036] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. In some aspects, MTC and eMTC UEs include robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node can provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered Intemet-of-Things (IoT) devices, and / or can be implemented as NB-IoT (narrowband

[0037] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a particular RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, and / or the like. Frequencies can also be referred to as carriers, frequency channels, and / or the like. Each frequency can support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to transmit information from the one UE 120 to the other UE 120). In some aspects, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110. In some aspects, one or more of the base stations 110 can be configured to operate as a master node, a child node, or a parent node. In some aspects, one or more of the base stations 110 can be configured to operate as a control base station, a central node, or a donor node. In some aspects, one or more of the base stations 110 can be configured to operate as a relay station.

[0039] Devices of wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided based on frequency or wavelength into various classes, bands, channels, and so on. In some aspects, devices of wireless network 100 can communicate using operating bands having a first frequency range (FR1), from 410 MHz to 7.125 GHz, and / or can communicate using operating bands having a second frequency range (FR2), from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” frequency band. Similarly, FR2 is often referred to as a “millimeter wave” frequency band despite being different from the extremely high frequency (EHF) frequency band identified by the International Telecommunications Union (ITU) as spanning from 30 GHz to 300 GHz. Thus, unless otherwise noted, the use of the term “sub-6 GHz” herein can generally be taken to mean frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise noted, the use of the term “millimeter wave” herein can generally be taken to mean frequencies within the EHF frequency band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and thus the techniques described herein are applicable to those modified frequency ranges.

[0040] As indicated above, providing Figure 1 as an example. Other examples can differ Figure 1 from the described examples.

[0041] Figure 2 FIG. 1 is a diagram illustrating an example 100 of a wireless network, in accordance with the present disclosure. The wireless network can include one or more base stations 110, one or more UEs 120, and / or one or more core networks 130, which can be in communication with one another.

[0042] At the base station 110, a transmit processor 220 can receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 can also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 can also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and / or the reference symbols, if applicable, and can provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 can process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t can be transmitted via T antennas 234a through 234t, respectively.

[0043] At the UE 120, the antennas 252a-252r can receive the downlink signals from the base station 110 and / or other base stations and can provide received signals to the demodulators (DEMODs) 254a-254r, respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 can obtain received symbols from all R demodulators 254a-254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term “controller / processor” can refer to one or more controllers, one or more processors, or combinations thereof. A channel processor can determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or channel quality indicator (CQI) parameters, among other examples. In some aspects, one or more components of UE 120 can be included in a housing 284.

[0044] The network controller 130 can include a communication unit 294, a controller / processor 290, and a memory 292. In some aspects, the network controller 130 can include one or more devices in a core network. The network controller 130 can communicate with the base station 110 via the communication unit 294.

[0045] Antennas (e.g., antennas 234a-234t and / or antennas 252a-252r) can include or can be included in one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include a set of co-planar antenna elements and / or a set of non-co-planar antenna elements. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include antenna elements within a single housing and / or antenna elements within multiple housings. An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements coupled to one or more transmit and / or receive components, such as one or more components of a transceiver 264 and / or a wireless communication management component 270. Figure 2 An antenna panel, antenna group, set of antenna elements, and / or antenna array can include one or more antenna elements coupled to one or more components of a transceiver 264 and / or a wireless communication management component 270.

[0046] On the uplink, at UE 120, a transmit processor 264 can receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, and / or CQI) from controller / processor 280. Transmit processor 264 can also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 can be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 254) of the UE 120 can be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver can include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. In some aspects, such as aspects described with reference to Figures 6-8 The transceiver can be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0047] At base station 110, the uplink signals from UE 120 and other UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 can provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Base station 110 can include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 can include scheduler 246 to schedule UEs 120 for downlink and / or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD / DEMOD 232) of the base station 110 can be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver can include any combination of antenna(s) 234, modulators and / or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (such as aspects described with reference to Figures 6-8 ).

In some aspects, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, transformation, and / or interpretation), these one or more instructions may cause one or more processors, UE 120, and / or base station 110 to perform or direct (in some aspects) their operation.

The UEs 305-1 and 305-2 can communicate using the one or more sidelink channels 310 for P2P communication, D2D communication, V2X communication (e.g., which can include V2V communication, V2I communication, vehicle-to-pedestrian (V2P) communication, etc.), mesh networking, etc. In some aspects, the UEs 305 (e.g., UE 305-1 and / or UE 305-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, the one or more sidelink channels 310 can use a PC5 interface and / or can operate in a high frequency band (e.g., a 5.9 GHz band). Additionally, or alternatively, the UEs 305 can synchronize timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, symbols, etc.) using global navigation satellite system (GNSS) timing.

[0055] As Figure 3As further shown, one or more sidelink channels 310 can include a physical sidelink control channel (PSCCH) 315, a physical sidelink shared channel (PSSCH) 320, and / or a physical sidelink feedback channel (PSFCH) 325. The PSCCH 315 can be used to convey control information similar to a physical downlink control channel (PDCCH) and / or a physical uplink control channel (PUCCH) used for cellular communications with base stations 110 via an access link or access channel. The PSSCH 320 can be used to convey data similar to a physical downlink shared channel (PDSCH) and / or a physical uplink shared channel (PUSCH) used for cellular communications with base stations 110 via an access link or access channel. In some aspects, the PSCCH 315 can carry sidelink control information (SCI) 330, which can indicate various control information for a sidelink communication, such as one or more resources (e.g., time resources, frequency resources, spatial resources, etc.) in which a transport block (TB) 335 can be carried on the PSSCH 320. The TB 335 can include data. The PSFCH 325 can be used to convey sidelink feedback 340, such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement or negative acknowledgement (ACK / NACK) information), transmission power control (TPC), scheduling request (SR), etc.

[0056] In some aspects, the one or more sidelink channels 310 can use a resource pool. In some aspects, a scheduling assignment (e.g., included in the SCI 330) can be transmitted in a subchannel using specific resource blocks (RBs) across time. In some aspects, a data transmission associated with the scheduling assignment (e.g., on the PSSCH 320) can occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, the scheduling assignment and the associated data transmission are not transmitted on adjacent RBs.

[0057] In some aspects, the UE 305 can operate using a transmission mode in which resource selection and / or scheduling is performed by the UE 305 (e.g., rather than by a base station 110). In some aspects, the UE 305 can perform resource selection and / or scheduling by sensing channel availability for transmissions. In some aspects, the UE 305 can measure a received signal strength indicator (RSSI) parameter (e.g., a sidelink RSSI (S-RSSI) parameter) associated with various sidelink channels, can measure a reference signal received power (RSRP) parameter (e.g., a PSSCH-RSRP parameter) associated with various sidelink channels, can measure a reference signal received quality (RSRQ) parameter (e.g., a PSSCH-RSRQ parameter) associated with various sidelink channels, etc., and can select a channel for a transmission of a sidelink communication based at least in part on these measurements.

[0058] Additionally or alternatively, the UE 305 can perform resource selection and / or scheduling using SCI 330 received in the PSCCH 315, which can indicate occupied resources, channel parameters, and / or the like. Additionally or alternatively, the UE 305 can perform resource selection and / or scheduling by determining a channel busy ratio (CBR) associated with various sidelink channels, which can be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 305 can use for a particular set of subframes).

[0059] In transmission modes in which resource selection and / or scheduling is performed by the UE 305, the UE 305 can generate a sidelink grant and can transmit the grant in the SCI 330. In some aspects, the sidelink grant can indicate one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks to be used for a sidelink transmission on the upcoming PSSCH 320 (e.g., for the TB 335), one or more subframes to be used for the upcoming sidelink transmission, a modulation and coding scheme (MCS) to be used for the upcoming sidelink transmission, and / or the like. In some aspects, the UE 305 can generate a sidelink grant indicating one or more parameters of a semi-persistent scheduling (SPS), such as a periodicity of sidelink transmissions. Additionally or alternatively, the UE 305 can generate a sidelink grant for event-driven scheduling, such as for on-demand sidelink messages.

[0060] As indicated above, providing Figure 3 as an example. Other examples can differ Figure 3 from the described examples.

[0061] Figure 4 is a diagram illustrating an example 400 of sidelink communications and access link communications, in accordance with the present disclosure.

[0062] As Figure 4 shown in FIG. 3, the transmitter (Tx) / receiver (Rx) UE 405 and the Rx / Tx UE 410 can communicate with one another via a sidelink, as described above with respect to Figure 3 FIG. 2. As further shown, in some sidelink modes, the base station 110 can communicate with the Tx / Rx UE 405 via a first access link. Additionally or alternatively, in some sidelink modes, the base station 110 can communicate with the Rx / Tx UE 410 via a second access link. The Tx / Rx UE 405 and / or the Rx / Tx UE 410 can correspond to one or more UEs described elsewhere herein, such as the UE 305. Figure 1A direct link (e.g., via a PC5 interface) between UEs 120 can be referred to as a sidelink, and a direct link (e.g., via a Uu interface) between a base station 110 and a UE 120 can be referred to as an access link. Sidelink communications can be transmitted via a sidelink, and access link communications can be transmitted via an access link. Access link communications can be either downlink communications (from a base station 110 to a UE 120) or uplink communications (from a UE 120 to a base station 110).

[0063] As indicated above, providing Figure 4 as an example. Other examples can differ with respect to Figure 4 the described.

[0064] Figure 5A and Figure 5B are diagrams illustrating examples 500 and 550 of sidelink communications in a star topology network according to the present disclosure.

[0065] As Figure 5A and shown in example 500, the base station 110, one or more hub UEs 505, and one or more UEs 510 can communicate in a star topology network. The one or more hub UEs 505 can generate data to control operation of the one or more UEs 510. In some aspects, the wireless network can include an industrial internet of things (IoT) environment. In some aspects, the hub UEs 505 can be associated with programmable logic controllers (PLCs) and the UEs 510 can be associated with sensor / actuator devices. The wirelessly connected hub UEs 505 can be positioned near factory equipment and / or devices (e.g., sensors / actuators). In some aspects, the hub UEs 505 can be positioned near the UEs 510, while the base station 110 can be mounted on a ceiling or a large distance from the UEs 510. In some aspects, a majority of communications within the star topology network can be sidelink communications (e.g., between a hub UE 505 and a UE 510, between two UEs 510, between two hub UEs 505, etc.).

[0066] As Figure 5A indicated in example 500, the base station 110 can transmit scheduling information to the hub UEs 505 and / or the UEs 510 using a direct link (e.g., a Uu link). The scheduling information can include a resource allocation for each communication between a hub UE 510 and an associated UE 505. Alternatively, the scheduling information can include a resource allocation that the hub UEs 505 can use to allocate resources for individual communications between the hub UEs 505 and the associated UEs 510. As Figure 5AAs shown in FIG. 5, hub UEs can communicate with UEs 510 using direct communication links (e.g., one or more sidelinks).

[0067] In some aspects, the star topology network can utilize mode 1 channel access (e.g., in which a base station 110 provides dynamic grants to hub UEs 505 and / or UEs 510 for sidelink communications). In some aspects, a transmitting UE (e.g., a hub UE 505 or a UE 510 requesting to transmit a sidelink communication) can request resources for a sidelink communication from a base station 110. During the resource request procedure, the base station 110 can assign a sidelink radio network temporary identifier (SL-RNTI) to the transmitting UE. If the base station 110 grants the sidelink resource request, the base station 110 indicates the resource allocation for PSCCH and PSSCH in downlink control information (DCI) transmitted by PDCCH scrambled with the SL-RNTI. When the transmitting UE receives such DCI, the transmitting UE can obtain the grant only if the scrambled DCI can be successfully resolved by the designated SL-RNTI. The transmitting UE then indicates the time-frequency resources and the transmission scheme of the allocated PSSCH in PSCCH and initiates PSCCH and PSSCH on the allocated resources for the sidelink communication. When the grant is obtained from the gNB, the transmitting UE can only transmit a single transport block. However, as described above, allocating resources for sidelink communications in this manner requires a large amount of signaling overhead.

[0068] In some aspects, the base station 110 can utilize configured grants (CGs) to schedule and / or allocate resources for sidelink communications. In some aspects, prior to traffic arriving at the transmitting UE, the transmitting UE can perform a similar request procedure as described above with respect to dynamic grants and can request a set of resources. If the grant can be obtained from the base station 110, the requested resources are reserved in a periodic manner. In some aspects, the base station 110 can configure periodic CG occasions (e.g., sidelink transmission opportunities) for the transmitting UE. Each CG occasion can be associated with resources granted by the base station 110 (e.g., specific periodic time slots in the time domain and / or specific sub-channels in the frequency domain designated for sidelink communications). When traffic arrives at the transmitting UE, the transmitting UE can transmit PSCCH and / or PSSCH in an upcoming CG occasion. The transmitting UE can report the CG sidelink transmission to the base station 110 to request a dynamic grant for retransmission. Additionally or alternatively, the transmitting UE can report the CG sidelink transmission to the base station 110 so that the base station 110 can perform channel congestion control for the star topology network.

[0069] CG resource allocation can reduce signaling overhead for star-topology networks. In addition, CG resource allocation can enable a base station 110 to coordinate channel access to avoid transmission collisions among UEs that can occur based at least in part on using mode-1 channel access or mode-2 channel access (e.g., where UEs sense to autonomously occupy and / or reserve channel access prior to transmission).

[0070] As Figure 5B As shown in example 550, a first UE, a second UE, a third UE, and a fourth UE (“UEs”) communicate via a hub UE. Although shown as UEs, the hub can include any type of wireless computing device, such as a base station, a control node, a machine-type communication UE, etc. In some aspects, the hub UE and the UEs can be outside of a coverage area supported by a base station (e.g., the hub UE and the UEs can not be in a cell of the base station). In some aspects, the hub UE can be associated with a programmable logic controller (PLC) in an industrial IoT environment. The UEs can be associated with devices such as sensors / actuators in an industrial IoT environment. Although Figure 5B Although four UEs are shown in example 550, the hub UE can be associated with tens of UEs. Similarly, although one star-topology network is shown, the wireless network can include multiple star-topology networks operating in a similar manner as described herein.

[0071] As shown by reference numbers 555, 560, 565, and 570, a first sidelink communication link can facilitate communication between the first UE and the hub UE, a second sidelink communication link can facilitate communication between the second UE and the hub UE, a third sidelink communication link can facilitate communication between the third UE and the hub UE, and a fourth sidelink communication link can facilitate communication between the fourth UE and the hub UE. The UEs can communicate directly with the hub, can communicate with other UEs via the hub, can communicate directly with other UEs via direct sidelink communication links, etc.

[0072] In this way, the hub can perform control and / or scheduling procedures for the UEs to improve scheduling conflicts among the UEs. However, many networks use protocols designed for peer-to-peer topologies, which can be inefficient for star-topology networks. In some aspects, the UEs can use sensing (e.g., listen-before-talk (LBT) protocols) to attempt to transmit control information (e.g., HARQ feedback) in a configured number of slots from receiving a PSSCH communication. However, the channel can be occupied, and the UEs can not be able to transmit the control information. In another case, transmission conflicts among the UEs can occur based at least in part on using mode-2 channel access (e.g., in cases where the UEs sense to autonomously occupy and / or reserve channel access prior to transmission). Additionally or alternatively, inter-UE blocking based on type-1 LBT can occur in unlicensed bands. Further, the UEs can be forced to rely on blind retransmissions based at least in part on half-duplex deafness of the hub. In some aspects, the hub UE can communicate with one or more other hub UEs (e.g., associated with other star-topology networks) to coordinate control and / or scheduling procedures for the UEs to improve scheduling conflicts among the UEs.

[0073] Some networks are aware of star topologies and can use reservation link scheduling via upper layer protocols on the physical layer or medium access control (MAC) layer of the network. In some aspects, a hub UE can announce that the hub is designated as a hub in the application layer and use the upper layer protocol to perform one or more control operations. The one or more control operations can include probing for traffic-related information from UEs, scheduling transmissions from multiple UEs without conflict (e.g., using upper layer-based scheduling, such as radio network controller-based scheduling in UMTS networks), scheduling wake-up timing for one or more UEs to save power, and the like.

[0074] In some aspects, the hub UE can not be able to control and / or schedule the UEs using dynamic grants (e.g., schedule communications based at least in part on requests from the UEs). Rather, the hub UE can utilize CGs to coordinate sidelink communications within the star-topology network. The hub UE can utilize the CGs to coordinate the sidelink communications in a similar manner as described above with respect to Figure 5A In some aspects, the hub UE can utilize the CGs to coordinate sidelink communications in a similar manner as described above with respect to

[0075] As indicated above, providing Figure 5A and Figure 5B are examples. Other examples can differ from what is described with respect to Figure 5A and Figure 5B .

[0076] A sidelink CG for mode 1 channel access (e.g., where a base station, hub UE, etc. grants a CG to a UE for sidelink communications) can specify resources associated with the CG. In some aspects, a sidelink transmitting UE can be configured with a CG that indicates a set of time-frequency resources that the sidelink transmitting UE is to use for a sidelink transmission. The set of time-frequency resources can be per CG occasion. The CG occasions can be configured periodically (e.g., the CG occasions can be configured to occur according to a periodicity). The sidelink transmitting UE can receive the time-domain resources and the frequency-domain resources associated with the sidelink CG using radio resource control (RRC) signaling (e.g., from a base station, hub UE, etc.). In some aspects, the sidelink transmitting UE can receive the time-domain resources associated with the sidelink CG using RRC signaling. The sidelink transmitting UE can receive the frequency-domain resources using downlink control information signaling that activates the specified frequency-domain resources (e.g., a particular subchannel, a set of RBs, etc.). In both cases, the resources allocated to the sidelink transmitting UE are specified such that the sidelink transmitting UE can only use the configured frequency-domain resources at periodic time slots (e.g., at periodic CG occasions).

[0077] This manner of resource allocation for a sidelink CG can be effective when the sidelink traffic follows a known or regular pattern. In some aspects, the sidelink traffic can be deterministic in that a base station or hub UE can know the periodicity or pattern associated with the sidelink traffic. Thus, the sidelink transmitting UE can be configured with resources and CG occasions that align with the known or regular pattern associated with the sidelink traffic. However, if the sidelink traffic is indeterminate or does not follow a known or regular pattern, the above manner of resource allocation for a sidelink CG can be insufficient. In some aspects, where the indeterminate sidelink traffic is associated with important latency requirements, the sidelink transmitting UE can need more time-frequency resources at each CG occasion to meet the important latency requirements. However, the increased time-frequency resources at each CG occasion can result in increased channel congestion within the wireless network. Thus, quality of service (QoS) can be negatively impacted as the increased channel congestion can decrease data rates within the wireless network, decrease throughput, increase latency, decrease capacity, increase packet loss, etc.

[0078] Some techniques and apparatuses described herein implement sidelink CGs that indicate resource pools and channel occupancy control parameters for CG sidelink communications. In some aspects, a sidelink transmission UE can receive a configuration of a sidelink CG that indicates a resource pool for each CG occasion. The sidelink transmission UE can determine a local channel occupancy status and select resources from the resources for sidelink transmissions based at least in part on comparing the local channel occupancy status to a channel occupancy control parameter. In this way, if the sidelink traffic follows an assumed or known traffic pattern, the sidelink transmission UE can use a relatively large amount of resources. Moreover, if the sidelink traffic does not follow the assumed or known traffic pattern, or if the sidelink transmission UE determines a high local channel occupancy status, the sidelink transmission UE is able to adjust the sidelink transmission UE’s channel access. Thus, in cases where the sidelink traffic does not follow a known or regular pattern and is associated with important latency requirements, the QoS of the wireless network is improved because the sidelink transmission UE can have a large resource pool within the bounds of the channel occupancy control parameter to select the sidelink transmission. Moreover, because the sidelink transmission UE can adjust its own channel access, the signaling overhead between the sidelink transmission UE and the base station or other UEs associated with channel congestion control is reduced.

[0079] Figure 6 is a diagram illustrating an example 600 associated with configured grant sidelink communications, in accordance with the present disclosure. As shown, a wireless communication device (WCD) 605 (e.g., a UE 120, a base station 110, etc.) can communicate with one or more UEs 120 (e.g., a UE 120). The WCD 605 and the one or more UEs 120 can be part of a wireless network (e.g., the wireless network 100). In some aspects, the WCD 605 can be configured to operate as a hub for one or more UEs 120 within the network (e.g., as described above with respect to FIG. 1). In some aspects, the WCD 605 can be a base station 110, as described above with respect to FIG. 1. In some aspects, the WCD 605 can be a hub UE, as described above with respect to FIG. 1. Figure 6 Figure 5A and Figure 5B Figure 5A Figure 5B

[0080] ​​​​As shown by reference number 610, the WCD 605 can determine a configuration of a CG sidelink communication to be transmitted by the UE 120. The configuration of the CG sidelink communication can indicate a resource pool and a channel occupancy control parameter. The resource pool can be a set of resources (e.g., one or more resources) associated with the CG occasion indicated by the configuration of the CG sidelink communication. In some aspects, the resource pool can be a set of resources available to the UE 120 for a sidelink transmission for each CG occasion. The resource pool can include one or more slots in the time domain and one or more subchannels in the frequency domain. A subchannel can be a set of contiguous RBs (e.g., 10 RBs, etc.). The WCD 605 can determine the one or more slots and the one or more subchannels to be included in the resource pool. In some aspects, the one or more subchannels included in the resource pool can be contiguous in the frequency domain. In some aspects, the one or more subchannels included in the resource pool can be non-contiguous in the frequency domain (e.g., there can be one or more gaps of unallocated subchannels within the resource pool). In some aspects, the resource pool can include only a single resource available to the UE 120 (e.g., only a single slot and / or subchannel).

[0081] In some aspects, the WCD 605 can determine multiple resource pools associated with the CG occasion. In some aspects, the WCD 605 can determine that each CG occasion is associated with multiple resource pools. In some aspects, the multiple resource pools can occupy the same time domain resources. In some aspects, the multiple resource pools can occupy contiguous frequency domain resources. In some aspects, the multiple resource pools can occupy non-contiguous frequency domain resources (e.g., there can be gaps of unallocated frequency domain resources between the resource pools).

[0082] In some aspects, one or more of the plurality of resource pools can be exclusively associated with the UE 120 (e.g., used only by the UE 120). In some aspects, one or more of the plurality of resource pools is shared among multiple UEs 120. The WCD 605 can determine that one or more of the plurality of resource pools exclusively associated with the UE 120 can be associated with a first transmission power. The WCD 605 can determine that one or more of the plurality of resource pools shared among multiple UEs 120 can be associated with a second transmission power. In some aspects, the first transmission power can be lower than the second transmission power. In some aspects, the configuration of the CG sidelink communication can indicate that the UE 120 is to use resources included in one or more of the plurality of resource pools shared among multiple UEs 120 only after using all transmission opportunities in one or more of the plurality of resource pools exclusively associated with the UE 120. That is, one or more of the plurality of resource pools exclusively associated with the UE 120 can be associated with higher priority CG sidelink communications than one or more of the plurality of resource pools shared among multiple UEs 120.

[0083] In some aspects, the WCD 605 can determine a set of preference parameters associated with a set of resources included in a resource pool. In some aspects, the WCD 605 can determine a preferred occupation probability for a configured grant sidelink communication using the resource pool in a time domain, a frequency domain, and / or a spatial domain. In some aspects, the WCD 605 can determine a preference parameter corresponding to a time slot index, a preference parameter corresponding to a subchannel index, and / or the like. The preference parameter can indicate a weight or preference of a particular resource within the resource pool to the UE 120. In some aspects, the WCD 605 can determine that the UE 120 should use one or more subchannels more frequently than one or more other subchannels within the resource pool. The one or more subchannels to be used more frequently by the UE 120 can be associated with a higher preference parameter than the one or more other subchannels within the resource pool.

[0084] As described above, a CG occasion can be a sidelink transmission opportunity for the UE 120 (e.g., the UE 120 can transmit a sidelink communication during the CG occasion using resources associated with the CG occasion). The WCD 605 can determine a periodicity associated with the CG occasion. In some aspects, the WCD 605 can determine that the CG occasion is to occur once every T slots, where T is greater than or equal to 1. In some aspects, the WCD 605 can determine the periodicity of the CG occasion according to a number of symbols (e.g., OFDM symbols), according to an amount of time (e.g., the CG occasion is to occur once every N milliseconds, etc.), and / or the like. The configuration of the CG sidelink communication can indicate the periodicity associated with the CG occasion.

[0085] The WCD 605 can determine a transmission power control setting of the UE 120 associated with a configuration of CG sidelink communications. In some aspects, the WCD 605 can determine that the UE 120 is to use an open loop power control configuration for CG sidelink communications with the WCD 605 (e.g., in a case where the WCD 605 is a UE 120). In some aspects, the WCD 605 can determine that the UE 120 is to use an open loop power control configuration for CG sidelink communications with the WCD 605 and one or more other UEs 120. In some aspects, the WCD 605 can determine that the UE 120 is to use a partial power control configuration that is based at least in part on a partial power control configuration associated with a radio access technology (RAT) that is different from a RAT associated with the CG sidelink communications. In some aspects, the WCD 605 can configure the UE 120 to use a partial power control configuration inherited from an LTE RAT with one or more changed parameters (e.g., with a different a value, etc.). The transmission power control setting can be indicated to the UE 120 dynamically (e.g., using layer 1 control signaling, such as DCI signaling).

[0086] The WCD 605 can determine a channel occupancy control parameter associated with a configured grant sidelink communication to be transmitted by the UE 120. The channel occupancy control parameter can indicate a channel occupancy limit, such as a number of subchannels that the UE 120 is permitted to use within a number of consecutive CG occasions. In some aspects, the channel occupancy control parameter can be a channel occupancy ratio control parameter (e.g., indicating an allowable ratio of a number of subchannels used by the UE 120 to a total number of subchannels available to the UE 120). The channel occupancy control parameter can enable the UE 120 to adjust channel access of the UE 120 to avoid channel congestion within the wireless network, as described in more detail below.

[0087] In some aspects, the channel occupancy control parameter can be based at least in part on a CBR estimate determined by the UE 120. In some aspects, the WCD 605 can determine a CBR estimate pool. The CBR estimate pool can include a set of resource pools. In some aspects, the CBR estimate pool can include a resource pool indicated by the configuration for CG sidelink communications (e.g., a resource pool associated with the UE 120) and one or more other resource pools associated with one or more other UEs 120. In some aspects, the WCD 605 can determine one or more other resource pools to include in the CBR estimate pool based at least in part on determining that the one or more other resource pools overlap (e.g., overlap in a time domain, overlap in a frequency domain, and / or overlap in a spatial domain) with the resource pool associated with the UE 120.

[0088] The WCD 605 can determine a mapping of CBR values to channel occupancy limits. The channel occupancy limits can indicate that the UE 120 is permitted to use a number of subchannels for a number of consecutive CG occasions. The WCD 605 can transmit an indication of the mapping of CBR values to channel occupancy limits using a configuration of CG sidelink communications. In some aspects, the WCD 605 can transmit the indication of the mapping of CBR values to channel occupancy limits in another communication, such as in a system information block (SIB), an RRC communication, and / or the like.

[0089] As shown by reference number 615, the WCD 605 can transmit a configuration for sidelink CG communications to the UE 120. The WCD 605 can transmit the configuration for sidelink CG communications using RRC signaling, medium access control (MAC) control element (MAC-CE) signaling, DCI signaling, and / or the like.

[0090] In some aspects, the WCD 605 can transmit the configuration for sidelink CG communications using layer 3 signaling that indicates a resource pool, a channel occupancy control parameter, a periodicity associated with CG occasions, and / or the like. In some aspects, if the WCD 605 is a base station 110, the layer 3 signaling can include an RRC communication via a Uu link between the WCD 605 and the UE 120. If the WCD 605 is a UE 120 (e.g., a hub UE), the layer 3 signaling can include a sidelink RRC communication via a PC5 link between the WCD 605 and the UE 120.

[0091] In some aspects, the WCD 605 can transmit the configuration for sidelink CG communications using a combination of layer 3 signaling and layer 1 signaling that indicates a resource pool, a channel occupancy control parameter, a periodicity associated with CG occasions, and / or the like. In some aspects, the WCD 605 can use dynamic layer 1 signaling to indicate frequency domain resources to include in the resource pool. If the WCD 605 is a base station 110, the layer 1 signaling can include a DCI communication via a Uu link between the WCD 605 and the UE 120 (e.g., a DCI communication using DCI format 3 0, and / or the like). If the WCD 605 is a UE 120, the layer 1 signaling can include a SCI communication via a PC5 link between the WCD 605 and the UE 120. The UE 120 can receive the configuration for sidelink CG communications and identify the resource pool, the channel occupancy control parameter, the periodicity associated with CG occasions, and / or the like.

[0092] As shown by reference number 620, the UE 120 can determine a local channel occupancy state at the UE 120. In some aspects, the UE 120 can determine that the UE 120 has sidelink traffic to communicate. To select resources from the resource pool during a CG occasion, the UE 120 can first determine a local channel occupancy state at the UE 120. The local channel occupancy state can be a number of sub-channels used by the UE 120 over a number of previous CG occasions (e.g., a number of previous CG occasions indicated by the WCD 605). The UE 120 can determine a channel occupancy limit based at least in part on a channel occupancy control parameter indicated by a configuration of the sidelink CG communication. In some aspects, the channel occupancy control parameter can indicate the channel occupancy limit (e.g., a number of sub-channels permitted to be used by the UE 120 over a number of previous CG occasions).

[0093] In some aspects, the channel occupancy control parameter can indicate a CBR estimation pool, as described above. The UE 120 can determine a CBR of the CBR estimation pool. The UE 120 can determine the channel occupancy limit based at least in part on a mapping of CBR values to channel occupancy limits (e.g., indicated by the WCD 605, as described above).

[0094] In some aspects, the channel occupancy control parameter can indicate a sidelink transmission resource pool to be used by the UE 120 as a CBR estimation pool. The sidelink transmission resource pool can be all resources available for sidelink communications within a wireless network (e.g., sl-TxPoolScheduling, etc.). The UE 120 can determine the channel occupancy limit in a similar manner as described above with respect to mode-2 channel access. The UE 120 can determine the local channel occupancy state of the UE 120 in a similar manner as mode-2 channel access (e.g., taking into account scheduled channel usage). The UE 120 can determine the channel occupancy headroom value based at least in part on a difference between the channel occupancy limit and the local channel occupancy state associated with the resource pool. In other words, the CG occasion can be conditioned on, associated with, or based at least in part on the channel occupancy control parameter, as described in greater detail elsewhere herein. Figure 5A and Figure 5B In some aspects, the channel occupancy control parameter can indicate a CBR estimation pool, as described above. The UE 120 can determine a CBR of the CBR estimation pool. The UE 120 can determine the channel occupancy limit based at least in part on a mapping of CBR values to channel occupancy limits (e.g., indicated by the WCD 605, as described above).

[0095] In some aspects, the configuration of the CG sidelink communication can indicate that the resource pool is a sidelink transmission resource pool. The UE 120 can determine a CBR of the sidelink transmission resource pool. The UE 120 can determine a channel occupancy limit based at least in part on the CBR of the sidelink transmission resource pool. The UE 120 can determine a channel occupancy value associated with the sidelink transmission resource pool based at least in part on the scheduled channel usage. The UE 120 can determine a channel occupancy headroom value based at least in part on a difference between the channel occupancy limit and the channel occupancy value associated with the sidelink transmission resource pool.

[0096] In some aspects, the UE 120 can receive a dynamic channel occupancy command from the WCD 605 indicating a channel occupancy limit. In some aspects, the WCD 605 can transmit the dynamic channel occupancy command based at least in part on channel conditions within the wireless network, channel congestion, and / or the like. The dynamic channel occupancy command can indicate an updated or new channel occupancy limit for the UE 120 to use.

[0097] As shown by reference number 625, the UE 120 can select resources for the CG sidelink communication based at least in part on the channel occupancy control parameter. In other words, the UE 120 can use the CG occasion based at least in part on the channel occupancy control parameter. In some aspects, the UE 120 can determine a difference between the channel occupancy limit and the local channel occupancy state. The UE 120 can select resources for the CG sidelink communication at the upcoming CG occasion such that the local channel occupancy state does not exceed the channel occupancy limit. If the UE 120 determines that the local channel occupancy state is below the channel occupancy limit, the UE 120 can select more resources for the CG sidelink communication in the upcoming CG occasion. If the UE 120 determines that the local channel occupancy state is close to the channel occupancy limit, the UE 120 can select fewer resources for the CG sidelink communication in the upcoming CG occasion. If the UE 120 determines that the local channel occupancy state is greater than or equal to the channel occupancy limit, the UE 120 can determine that the UE 120 cannot transmit any sidelink communications in the upcoming CG occasion. In some aspects, the resource pool and / or the CG occasion can be associated with a single resource (e.g., a single time-domain resource and / or a frequency-domain resource). The UE 120 can select the single resource if selecting the single resource does not cause the local channel occupancy state to exceed the channel occupancy limit.

[0098] In some aspects, the UE 120 can select one or more resources from the resource pool if the number of resources for the CG sidelink communication during a number of consecutive CG occasions is less than the channel occupancy limit. As described above, the channel occupancy limit can be indicated by the channel occupancy control parameter, can be determined by the UE 120 based at least in part on a CBR value determined by the UE 120, and / or the like.

[0099] In some aspects, the UE 120 can select one or more resources for the CG sidelink communication based at least in part on a channel occupancy headroom value determined by the UE 120. In some aspects, the channel occupancy headroom value can indicate a quantity of resources available to the UE 120 for the CG sidelink communication. The UE 120 can select one or more resources in an amount up to the quantity of resources available to the UE 120 for the CG sidelink communication indicated by the channel occupancy headroom value.

[0100] In some aspects, as described above, the UE 120 can select one or more resources for the CG sidelink communication based at least in part on the set of preference parameters indicated by the WCD 605. In some aspects, the UE 120 can select one or more resources for the sidelink CG communication based at least in part on a first resource pool associated with a priority of the CG sidelink communication that is higher than a priority associated with a second resource pool (e.g., where a configuration of the CG sidelink communication indicates that each CG occasion is associated with multiple resource pools).

[0101] In some aspects, the UE 120 can be configured with a channel occupancy weighting matrix associated with the set of resources included in the resource pool. The channel occupancy weighting matrix can be indicated in a configuration of the sidelink CG communication. The channel occupancy weighting matrix can indicate one or more channel occupancy weights corresponding to one or more slot indices, one or more channel occupancy weights corresponding to one or more subchannel indices, and / or the like. When selecting resources for the CG sidelink communication, the UE 120 can use the channel occupancy weights in determining whether the selected resources would cause the UE 120 to exceed a channel occupancy limit. In some aspects, a subchannel index can be associated with a channel occupancy weight of 2. Thus, when determining a local channel occupancy status of the UE 120, if the UE 120 selects resources included in a subchannel indicated by the subchannel index, those resources would be twice as normal for the channel occupancy status. In this way, the WCD 605 can indicate a preference for certain resources included in the resource pool by associating other resources with a higher channel occupancy weight. Thus, the UE 120 can select resources associated with a lower channel occupancy weight more frequently than resources associated with a higher channel occupancy weight (e.g., such that the UE 120 ensures that the UE 120 does not exceed the channel occupancy limit).

[0102] The UE 120 can select any resources included in the resource pool so long as the selected resources do not cause the UE 120’s local channel occupancy to exceed the channel occupancy limit. In this way, the UE 120 can have flexibility in which resources the UE 120 selects and the number of resources the UE 120 selects during different CG occasions. In some aspects, at a first CG occasion, the UE 120 can select a first number of resources from the resource pool for a first CG sidelink communication. At a second CG occasion, the UE 120 can select a second number of resources from the resource pool for a second CG sidelink communication.

[0103] As shown by reference number 630, the UE 120 can transmit the CG sidelink communication during the CG occasion using the resources selected by the UE 120. In some aspects, the UE 120 can transmit the CG sidelink communication to the WCD 605 (e.g., when the WCD 605 is the UE 120). In some aspects, the UE 120 can transmit the CG sidelink communication to one or more other UEs 120. In some aspects, the UE 120 can transmit multiple transport blocks (TBs) during the CG occasion using the resources selected by the UE 120. The UE 120 can transmit the CG sidelink communication using the transmission power control settings indicated by the WCD 605.

[0104] Thus, in cases where sidelink traffic does not follow a known or regular pattern and is associated with important latency requirements, the QoS of the wireless network is improved because the UE 120 can have a large resource pool to select CG sidelink transmissions within the bounds of the channel occupancy control parameters. Moreover, because the UE 120 can regulate its own channel access, signaling overhead between the UE 120 and the WCD 605 associated with channel congestion control is reduced.

[0105] As indicated above, the techniques Figure 6 are examples. Other examples can vary Figure 6 from the examples described.
