[0003] background

[0004] Public domain

[0005] Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining resources for sidelink communications based on coordination information and / or sensing information.

[0006] Related technical description

[0007] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcast, etc. These wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access systems include Third Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, 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, and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, to name just a few.

[0008] These multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different wireless devices to communicate at city, country, region, and even global levels. New radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is an enhancement set of the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using OFDMA with cyclic prefix (CP) on downlink (DL) and uplink (UL) to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0009] As the demand for mobile broadband access continues to grow, there is a need for further improvements to NR and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies.

[0029] Detailed Description

[0030] Various aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for combining coordination information. In some aspects, combining coordination information may refer to assigning one or more rankings to the coordination information and prioritizing specific coordination information over other coordination information based on the rankings associated with the coordination information. Certain aspects of the present disclosure provide various techniques for combining coordination information from different sidelink sources (e.g., wireless communication devices, such as user equipment (UE), roadside units (RSU), or vehicles) and / or combining coordination information with sensing information measured at the UE. Sensing information may refer to one or more measurements of signals transmitted by one or more UEs. For example, the sensing information may include a reference signal received power (RSRP) measurement associated with a candidate resource pool for sidelink communication. In a situation where a UE relies solely on coordination information from other UEs for resource selection (e.g., time domain resources, frequency domain resources, and / or spatial resources), the techniques for combining coordination information described herein may facilitate the UE to avoid resource conflicts with other UEs (e.g., when two or more transmitting devices attempt to transmit on the same set of resources, causing these transmissions to interfere with each other at the receiving device) and / or provide a desired power consumption level. In various aspects, the techniques for combining coordination information described herein may enable a UE to have desired sidelink performance (eg, access time, latency, data rate, packet error rate, etc.) with target UE(s).

[0031] The following description provides an example of combining coordination information in a communication system for side link communication, without limiting the scope, applicability or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various examples may appropriately omit, replace, or add various procedures or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. Moreover, the features described with reference to some examples may be combined in some other examples. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using other structures, functionalities, or structures and functionalities as supplements to the various aspects of the present disclosure set forth herein or in addition. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of the claims. The wording "exemplary" is used herein to mean "used as an example, instance, or explanation". Any aspect described as "exemplary" herein is not necessarily to be interpreted as superior to or superior to other aspects.

[0032] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as a radio technology, air interface, etc. Frequency may also be referred to as a carrier, subcarrier, frequency channel, frequency tone, subband, etc. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs.

[0033] The techniques described herein can be used for various wireless networks and radio technologies. Although various aspects may be described herein using terms typically associated with 3G, 4G, and / or new radio (e.g., 5G NR) wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations.

[0034] Figure 1 An example wireless communication network 100 is illustrated in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be an NR system (e.g., a 5G NR network). According to certain aspects, the UEs 120a, 120b, 120c may be configured to combine coordination information according to aspects of the present disclosure. For example, according to aspects of the present disclosure, the UE 120a includes a resource manager 122a that determines, based on a plurality of ranked coordination information reports or coordination information and sensing information, resources from candidate resources for communicating with one or more other UEs (e.g., UEs 120b, 120c). In various aspects, the UEs 120b, 120c may also include similar or identical resource managers 122b, 122c, respectively.

[0035] In some cases, two or more subordinate entities (e.g., UE 120a, 120b, 120c) may use sidelink signals to communicate with each other. Real-world applications of such sidelink communications may include public safety, proximity services, UE-to-network relay, vehicle-to-vehicle (V2V) communications, Internet of Everything (IoE) communications, IoT communications, mission-critical mesh networks, and / or various other suitable applications. In general, a sidelink signal may refer to a signal that is communicated from one subordinate entity (e.g., UE 120a) to another subordinate entity (e.g., UE 120b) without relaying the communication through a scheduling entity (e.g., UE or BS), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, the sidelink signal may be communicated using a licensed spectrum (unlike a wireless local area network, which typically uses an unlicensed spectrum) or an unlicensed spectrum.

[0036] Various sidelink channels may be used for sidelink communications, including a physical sidelink discovery channel (PSDCH), a physical sidelink control channel (PSCCH), a physical sidelink shared channel (PSSCH), and a physical sidelink feedback channel (PSFCH). The PSDCH may carry discovery expressions that enable neighboring devices to discover each other. The PSCCH may carry control signaling (such as sidelink resource configuration and other parameters for data transmission), while the PSSCH may carry data transmission. The PSFCH may carry feedback including HARQ feedback and / or channel state feedback (CSF) related to sidelink channel quality.

[0037] like Figure 1 As illustrated in , the wireless communication network 100 may include multiple BSs 110a-z (each also individually referred to herein as BS 110, or collectively referred to as BS 110) and other network entities. BS 110 may provide communication coverage for a particular geographic area (sometimes referred to as a "cell"), which may be stationary or mobile depending on the location of the mobile BS 110. In some examples, BS 110 may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless communication network 100 via various types of backhaul interfaces (e.g., direct physical connections, wireless connections, virtual networks, etc.) using any suitable transport network. Figure 1 In the example shown in FIG. 1 , BSs 110a, 110b, and 110c may be macro BSs for macro cells 102a, 102b, and 102c, respectively. BS 110x may be a pico BS for pico cell 102x. BSs 110y and 110z may be femto BSs for femto cells 102y and 102z, respectively. A BS may support one or more cells.

[0038] BS 110 communicates with UEs 120a-y (each also individually referred to herein as UE 120, or collectively referred to as UE 120) in the wireless communication network 100. UEs 120 (e.g., 120x, 120y, etc.) may be dispersed throughout the wireless communication network 100, and each UE 120 may be stationary or mobile. The wireless communication network 100 may also include a relay station (e.g., relay station 110r) (also referred to as a relay, etc.) that receives transmissions of data and / or other information from an upstream station (e.g., BS 110a or UE 120r) and sends transmissions of the data and / or other information to a downstream station (e.g., UE 120 or BS 110), or that relays transmissions between UEs 120 to facilitate communication between the devices.

[0039] The network controller 130 may communicate with a set of BSs 110 and provide coordination and control (e.g., via a backhaul) of the BSs 110. In various aspects, the network controller 130 may be in communication with a core network 132 (e.g., a 5G core network (5GC)) that provides various network functions, such as access and mobility management, session management, user plane functions, policy control functions, authentication server functions, unified data management, application functions, network exposure functions, network repository functions, network slice selection functions, etc.

[0040] NR access can support various wireless communication services, such as enhanced mobile broadband (eMBB) targeting wide bandwidth (e.g., 80 MHz or more), millimeter wave (mmW) targeting high carrier frequency (e.g., 24 GHz to 53 GHz or more), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC technology, and / or mission critical services targeting ultra-reliable low latency communication (URLLC). These services may include latency and reliability requirements. These services may also have different transmission time intervals (TTIs) to meet corresponding quality of service (QoS) requirements. In addition, these services can coexist in the same subframe. NR supports beamforming and the beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. MIMO configuration in DL can support up to 8 transmit antennas (with multi-layer DL transmission of up to 8 streams) and up to 2 streams per UE. Multi-layer transmission of up to 2 streams per UE can be supported. Aggregation of multiple cells can be supported using up to 8 serving cells.

[0041] NR can utilize orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) on uplink and downlink. NR can support half-duplex operation using time division duplex (TDD). OFDM and single carrier frequency division multiplexing (SC-FDM) divide the system bandwidth into multiple orthogonal subcarriers, which are also often called frequency modulation, frequency slot, etc. Each subcarrier can be modulated with data. Modulation codewords can be sent in the frequency domain with OFDM and in the time domain with SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers can depend on the system bandwidth. The minimum resource allocation (so-called resource block (RB)) can be 12 consecutive subcarriers. The system bandwidth can also be divided into subbands. For example, one subband can cover multiple RBs. NR can support a base subcarrier spacing (SCS) of 15KHz, and other SCSs (e.g., 30kHz, 60kHz, 120kHz, 240kHz, etc.) can be defined relative to the base SCS.

[0042] Figure 21 and 120a (eg, Figure 1 Example components of a wireless communication network 100).

[0043] At BS 110a, transmit processor 220 may receive data from data source 212 and control information from controller / processor 240. The control information may be for a physical broadcast channel (PBCH), a physical control format indicator channel (PCFICH), a physical hybrid ARQ indicator channel (PHICH), a physical downlink control channel (PDCCH), a group common PDCCH (GC PDCCH), etc. The data may be for a physical downlink shared channel (PDSCH), etc. A medium access control (MAC)-control element (MAC-CE) is a MAC layer communication structure that may be used for control command exchange between wireless nodes. The MAC-CE may be carried in a shared channel, such as a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical sidelink shared channel (PSSCH).

[0044] The processor 220 may process (e.g., encode and symbol map) data and control information to obtain data symbols and control symbols, respectively. The transmit processor 220 may also generate reference symbols (such as for a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a PBCH demodulation reference signal (DMRS), and a channel state information reference signal (CSI-RS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, and / or reference symbols, where applicable, and may provide an output symbol stream to a modulator (MOD) 232a-232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The downlink signals from the modulators 232a-232t may be transmitted via antennas 234a-234t, respectively.

[0045] At UE 120a, antennas 252a-252r may receive downlink signals from BS 110a and may provide received signals to demodulators (DEMODs) 254a-254r in the transceiver, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a respective received signal to obtain input samples. Each demodulator may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all demodulators in transceivers 254a-254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 120a to a data sink 260, and provide decoded control information to a controller / processor 280.

[0046] On the uplink, at the UE 120a, a transmit processor 264 may receive and process data from a data source 262 (e.g., for a physical uplink shared channel (PUSCH)) and control information from a controller / processor 280 (e.g., for a physical uplink control channel (PUCCH)). The transmit processor 264 may also generate reference symbols for reference signals (e.g., a sounding reference signal (SRS)). The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a-254r in the transceiver (e.g., for SC-FDM, etc.), and transmitted to the BS 110a. At the BS 110a, the uplink signal from the UE 120a may be received by the antenna 234, processed by the modulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120a. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240 .

[0047] Memories 242 and 282 may store data and program codes for BS 110a and UE 120a, respectively.A scheduler 244 may schedule UEs for data transmission on the downlink and / or uplink.

[0048] The antennas 252, processors 266, 258, 264 and / or controller / processor 280 of the UE 120a, and / or the antennas 234, processors 220, 230, 238 and / or controller / processor 240 of the BS 110a may be used to perform the various techniques and methods described herein. Figure 2As shown in FIG. 1 , according to aspects of the present disclosure, a controller / processor 280 of a UE 120a has a resource manager 281 that determines, based on a plurality of ranked coordination information reports or coordination information and sensing information, candidate resources for communicating with one or more other UEs (e.g., Figure 1 Although illustrated as being at the controller / processor, other components of the UE 120a and BS 110a may also be used to perform the operations described herein.

[0049] Although Figure 2 The example depicted in FIG. 1 is described with respect to communication between BS 110a and UE 120a, but aspects of the present disclosure may also be applied to sidelink communications between UEs, such as between UE 120a and UE 120b, between UE 120a and UE 120c, or between UE 120b and UE 120c, as shown in FIG. Figure 1 As depicted in .

[0050] Figure 3 300 is a diagram showing an example of a frame format for NR. The transmission timeline of each of the downlink and uplink may be divided into units of radio frames. Each radio frame may have a predetermined duration (e.g., 10 ms) and may be divided into 10 subframes with indices 0 to 9, each subframe being 1 ms. Each subframe may include a variable number of slots (e.g., 1, 2, 4, 8, 16, ... slots), depending on the SCS. Each slot may include a variable number of symbol periods (e.g., 7, 12, or 14 symbols), depending on the SCS. An index may be assigned to the symbol period in each slot. A mini slot (which may be referred to as a subslot structure) refers to a transmission time interval having a duration less than a slot (e.g., 2, 3, or 4 symbols). Each symbol in a slot may indicate a link direction (e.g., DL, UL, or flexible) for data transmission, and the link direction for each subframe may be dynamically switched. The link direction may be based on the slot format. Each time slot may include DL / UL data and DL / UL control information.

[0051] In NR, synchronization signal blocks (SSBs) are transmitted. In certain aspects, each SSB may be transmitted in a burst, where each SSB in the burst corresponds to a different beam direction for UE-side beam management (e.g., including beam selection and / or beam refinement). The SSBs include the PSS, SSS, and a two-symbol PBCH. The SSBs may be transmitted at fixed timeslot locations (such as Figure 3) is transmitted in the codewords 0-3 shown in . PSS and SSS can be used by UE for cell search and acquisition. PSS can provide half-frame timing, and SS can provide CP length and frame timing. PSS and SSS can provide cell identity. PBCH carries some basic system information, such as downlink system bandwidth, timing information within radio frames, SS burst set periodicity, system frame number, etc. SSB can be organized into SS bursts to support beam sweeping. Further system information (such as remaining minimum system information (RMSI), system information block (SIB), other system information (OSI)) can be transmitted on the physical downlink shared channel (PDSCH) in certain subframes. SSB can be transmitted up to 64 times, for example, up to 64 different beam directions for millimeter waves. Multiple transmissions of SSB are called SS burst sets. SSBs in an SS burst set can be transmitted in the same frequency region, while SSBs in different SS burst sets can be transmitted in different frequency regions.

[0052] Figure 4A and 4B A vehicle-to-everything (V2X) system according to certain aspects of the present disclosure is illustrated. Figure 4A and 4B The V2X system provided in the present invention provides two complementary transmission modes. The first transmission mode involves direct communication between participants in a local area (e.g., also referred to herein as sidelink communication between UEs). Such communication is carried out in a Figure 4A The second transmission mode involves Figure 4B The network communication through the network explained in , the network communication may be implemented through a Uu interface (eg, a wireless communication interface between a radio access network (RAN) and a UE).

[0053] Reference Figure 4A, the V2X system is illustrated as having two vehicles. The first transmission mode allows direct communication between different participants in a given geographic location. As illustrated, the first vehicle 402 may have a wireless communication link (V2P) with a personal UE 404 through a PC5 interface. Communication (V2V) between the first vehicle 402 and the second vehicle 406 may also occur through the PC5 interface. Communication (V2I) from the first vehicle 402 to a roadside unit 408 (RSU) (such as a traffic signal or sign) may occur through the PC5 interface in a similar manner. In each of the illustrated examples, bidirectional communication may be performed between the elements, so each element may be a transmitter and receiver of information. In the configuration provided, the first transmission mode may be a self-management system without assistance from a network (such as a RAN). Such transmission modes may achieve improved spectral efficiency, reduced costs, and increased reliability because network service interruptions do not occur during switching operations for moving vehicles. Resource assignment does not require coordination between drivers or subscriptions to the network, thereby reducing the complexity of such self-management systems. V2X systems can be configured to operate in licensed or unlicensed spectrum, whereby any vehicle with an equipped system can access a common frequency and share information. Such coordinated / shared spectrum operations allow for safe operation.

[0054] Reference Figure 4B , illustrating the second transmission mode of the two complementary transmission modes. In the illustrated embodiment, the third vehicle 410 can communicate with the fourth vehicle 412 via network communications. These network communications can occur through discrete nodes (such as BS (e.g., eNB or gNB)) that send and receive information between the vehicles. Network communications can be used for long-range communications between vehicles, such as notifying an accident at a distance. Other types of communications, such as traffic flow conditions, road hazard warnings, environmental / weather reports, service station availability, and other similar data, can be sent by the nodes to the vehicles (410, 412). Such data can be obtained from a cloud-based sharing service.

[0055] Example combined coordination information

[0056] In some wireless communication systems (e.g., 5G NR systems), resource allocation for sidelink communication may be a reservation based on a network scheduling mode or an autonomous mode. In autonomous mode, a UE may select resources from a shared pool and reserve the selected resources by transmitting a reservation to one or more other UEs. In some cases, a transmission with reservation information may reserve resources in the current time slot (or other suitable time period) in which the transmission is received and in the future up to a specific number of time slots (or other suitable time periods) (e.g., two time slots in the future). For example, the reservation information may be carried in the sidelink control information (SCI). Resource reservation may be periodic or aperiodic. In some cases, the period may be signaled in the SCI with a configurable value between 0 milliseconds (ms) and 1000 milliseconds. Periodic resource reservation and signaling may be disabled by configuration or preconfigured to be disabled.

[0057] In an autonomous mode for sidelink communication, a UE may perform resource selection by identifying candidate resources in a resource pool and selecting one or more of the candidate resources for sidelink communication with one or more other UEs. The UE may identify candidate resources by monitoring the resources in the resource pool and excluding certain resources based on various attributes associated with these resources, such as reference signal received power (RSRP) measurements. In some cases, the reserved resources may be preempted by a higher priority reservation made by another UE. The selected but not yet reserved resources may be reserved by another UE, and in such cases, the resource selection procedure may be triggered again.

[0058] Figure 5 A diagram illustrating an example resource sensing window and an example resource selection window according to certain aspects of the present disclosure. The UE may determine whether candidate resources within the resource selection window 502 are available by decoding each side link transmission (e.g., the first and second transmissions 504, 506) and measuring various attributes associated with each transmission within the sensing window 508. The candidate resources may include frequency-time resources in the resource selection window 502. In various aspects, the transmissions 504, 506 may carry an SCI with one or more reservations within the resource selection window 502. For example, the first transmission 504 may have an SCI that reserves resources 510, 512 in the resource selection window 502, and the second transmission 506 may have an SCI that reserves resources 514, 516 in the resource selection window 502. In certain aspects, the resource reservations in the transmissions 504, 506 may have a priority indicated in the SCI, which is also tracked as part of sensing and / or resource selection.

[0059] After the sensing window 508, for example, due to the sidelink traffic being generated at the UE, a resource selection procedure may be triggered at the UE. The UE may select resources from the resource selection window 502 based at least in part on the measurements made for the transmissions 504, 506 in the sensing window 508. For example, the RSRP of the transmissions 504, 506 may be projected onto the reserved resources 510, 512, 514, 516 in the resource selection window 502. That is, the RSRP measurement for the first transmission 504 may be projected onto the reserved resources 510, 512, and the RSRP measurement for the second transmission may be projected onto the reserved resources 514, 516. Resources in the resource selection window 502 with an RSRP less than or equal to a certain threshold may be considered available for sidelink communication. Other resources (such as candidate resources 518) may also be considered available for sidelink communication without any projected RSRP measurements. In other words, resources in the resource selection window 502 with relatively low interference levels or without interference from other UEs may be considered available for sidelink communication. In various aspects, RSRP may be used for various sidelink reference signals, such as reference signals associated with control and / or data portions of a sidelink transmission (e.g., demodulation reference signals).

[0060] In some cases, the priority associated with the resource in the resource selection window can also determine whether the resource is available. In various aspects, the priority associated with the resource can have a separately configurable RSRP threshold for comparison with the RSRP measurement. In some aspects, the priority can be a priority pair with a transmission priority and a reception priority, and each priority pair can have a separately configurable RSRP threshold for comparison with the RSRP measurement. For example, it is assumed that the resources 510, 512 are associated with a specific priority indicated in the SCI within the first transmission 504, so that the priority is associated with a certain RSRP threshold. The UE can determine whether the resources 510, 512 are available based on the RSRP threshold associated with the priority.

[0061] In some cases, the UE may receive coordination information associated with candidate resources from one or more other UEs. The coordination information may enable the UE to select resources for transmission to avoid resource conflicts. In some cases, the UE may perform resource selection based solely on the coordination information without taking any measurements during the sensing window. In this case, resource selection based on the coordination information may enable the UE to eliminate power consumption resulting from monitoring resources in the sensing window.

[0062] Figure 6An example of various sidelink transmissions in which a UE receives coordination information from multiple UEs according to certain aspects of the present disclosure is illustrated. The first and second UEs 120a, 120b can generate coordination information reports (e.g., RSRP measurements, transmission priorities, time slots, and / or location information corresponding to detected reservations) from resources in a monitoring sensing window (e.g., sensing window 508). The first and second UEs 120a, 120b can share coordination information reports with one or more other UEs (e.g., a third UE 120c). As used herein, a coordination information report can be a report including or indicating information associated with a candidate resource and / or information associated with the UE generating the report. The third UE 120c can determine one or more available resources for communicating with a target UE 120d from a resource selection window based on the coordination information reports received from the first and second UEs 120a, 120b. The third UE 120c can communicate with the target UE 120d via the determined resources. For example, the third UE 120c can transmit various signals to the target UE 120d via the determined resources.

[0063] In various aspects, the coordination information may include various information associated with the candidate resources and / or various information associated with the UE generating the coordination information. The coordination information may include an indication of which resources are available, an indication of which resources are not available, a set of resources to be used for communication, a set of resources to avoid being used for communication, an indication of conflicting reservations, or a combination thereof. Additionally or alternatively, the coordination information may include RSRP measurements, transmission priorities, time slots, and / or location information corresponding to the detected reservations. In certain aspects, the coordination information may further include the location of the UE generating the coordination information, a priority associated with the coordination information (e.g., a priority for reservation signaled in the SCI), a time indication of when the coordination information was generated, or a combination thereof.

[0064] Certain aspects of the present disclosure provide various techniques for combining coordination information from different sidelink sources (e.g., wireless communication devices such as UEs, RSUs, or vehicles) and / or combining coordination information with sensing information measured at the UE. In situations where the UE relies solely on coordination information from other UEs for resource selection, the techniques for combining coordination information described herein can enable the UE to avoid resource conflicts with other UEs and / or provide a desired power consumption level. In various aspects, the various techniques for combining coordination information described herein can enable the UE to have the desired sidelink performance (e.g., access time, latency, data rate, packet error rate, etc.) with the target UE(s).

[0065] In some cases, the UE may assign a ranking or order to the coordination information reports received from other UEs, and the UE may determine the resources available for sidelink communication based on the rankings of these coordination information reports. These rankings may enable the UE to determine which coordination information report is suitable for resource selection. That is, the UE may filter out certain coordination information reports based on these rankings.

[0066] For example, the UE may assign rankings to the coordination information reports based on the distance between the UE receiving the coordination information and the UE generating the coordination information report. Figure 6 , the third UE 120c may select the coordination information report from the UE (UE 120a, 120b) closest to the third UE 120c for determining available resources, assuming that the closest UE providing coordination information may be in a similar channel condition relative to the target UE when the UE receives the coordination information. Assume that the second UE 120b is closer to the third UE 120c than the first UE 120a. The third UE 120c may assign the coordination information from the second UE 120b with the highest ranking and select the coordination information for determining available resources for communicating with the target UE 120d.

[0067] In various aspects, the UE may select a coordination information report based on a ranking used to determine which coordination information is applicable for resource selection. In some cases, the UE may select the coordination information report with the highest ranking for use in the resource selection procedure. In some cases, the UE may select a subset of the ranked coordination information reports for use in the resource selection procedure. For example, if there are multiple coordination information reports with the highest ranking, the UE may select all coordination information reports with the highest ranking. In various aspects, the UE may select a specific number of ranked coordination information reports, such as the top three or top five coordination reports. In some cases, the UE may select all coordination information reports for use in resource selection.

[0068] In various aspects, if multiple coordination information reports are selected, a union or combination of the coordination information may be used for resource selection. In certain aspects, if a value or combination of values ​​is below a certain threshold, some of the coordination information may be discarded from the selected coordination information reports. In various aspects, the UE may use the coordination information and the sensing information for resource selection.

[0069] Figure 71 illustrates a signaling flow of example signaling 700 for combining coordination information in accordance with certain aspects of the present disclosure. As shown, at 702, a first UE 120a receives coordination information reports from one or more second UEs 120b. In some cases, at 704, the first UE 120a may receive coordination information reports from a target UE 120c. At 706, the first UE 120a may monitor resources within a sensing window and receive resource reservations from the second UE 120b via an SCI, e.g., as described herein with respect to Figure 5 As described herein. At 708, the first UE 120a may generate sensing information associated with the candidate resources, such as projecting the RSRP of each transmission received at 706 to the candidate resources within the resource selection window. At 710, the first UE 120a may assign a ranking to each coordination information report received at 702 and / or 704. At 712, the first UE 120a may determine one or more resources for communicating with the third UE 120c from the candidate resources in the resource selection window based on a plurality of ranked coordination information reports or a combination of the coordination information received at 702 and / or 704 and the sensing information generated at 708, as further described herein. At 714, the first UE 120a may communicate with the target UE 120c via the resources determined at 712. For example, the first UE 120a may transmit packets to the target UE 120c via various sidelink channels (e.g., PSSCH).

[0070] Although Figure 7 The examples depicted in the description are about coordination information and / or sensing information associated with a single target UE to facilitate understanding, but various aspects of the present disclosure may also be applied to coordination information and / or sensing information associated with multiple target UEs to facilitate groupcast (multicast) or broadcast communications with each target UE.

[0071] Figure 8 800 for wireless communication according to certain aspects of the present disclosure. Operations 800 may be performed, for example, by a wireless device (e.g., UE 120a, 120b, 120c in wireless communication network 100). As used herein, a wireless device may refer to a lower-level wireless communication device such as a user equipment, a wireless station, a roadside unit, etc. Operations 800 may be implemented as a processor (e.g., Figure 2 In addition, signal transmission and reception by the UE in operation 800 may be performed by one or more antennas (e.g., Figure 2In some aspects, signal transmission and / or reception by the UE may be achieved by obtaining and / or outputting signals via a bus interface of one or more processors (eg, controller / processor 280).

[0072] Operations 800 may begin at 802, where a first wireless device (e.g., Figure 6 UE 120c) from one or more second wireless devices (e.g., Figure 6 At 804, the first wireless device may assign one or more rankings to the one or more reports. At 806, the first wireless device may determine which of the candidate resources to use for coordination with one or more third wireless devices (e.g., Figure 6 The first wireless device may determine one or more resources for communicating with the target UE 120d) of the first wireless device: at least two reports from at least two of the one or more second wireless devices, and the ranking of the at least two reports; or at least one of the one or more reports and sensing information measured by the first wireless device and associated with the candidate resources, and the ranking of the at least one of the one or more reports and the ranking of the sensing information. At 808, the first wireless device may communicate with the one or more third wireless devices via the determined one or more resources.

[0073] In various aspects, determining the one or more resources at 806 may include the first wireless device performing a resource selection procedure using the coordination information and / or the sensing information. In various aspects, the UE may receive the coordination information from the one or more target UEs. For example, with respect to operation 800, the second wireless device may include at least one of the third wireless devices. In various aspects, communicating with the one or more third wireless devices at 808 may include the first wireless device transmitting a packet to the one or more third wireless devices via the determined one or more resources. For example, the first wireless device may communicate with the third wireless device via a sidelink transmission.

[0074] In various aspects, a first wireless device may assign a ranking or order to coordination information reports received from a second wireless device. In some cases, these rankings may be assigned to coordination information reports based on: RSRP measured for a transmission carrying coordination information; the location of a UE generating the coordination information; the location of a target UE for the transmission relative to the UE generating the coordination information; a distance between a UE receiving the coordination information and a UE generating the coordination information (which may be derived from the location); a distance between a UE generating the coordination information and a target UE for the transmission (which may be derived from the location); a priority for the coordination information; a source identifier associated with the UE generating the coordination information; when the coordination information was received; or staleness of the coordination information (e.g., when the coordination information was generated).

[0075] For example, one or more rankings may be assigned at 804 based on at least one of: one or more indications of channel quality between the first wireless device and one or more second wireless devices, one or more distances between the first wireless device and one or more second wireless devices, one or more distances between the one or more second wireless devices and one or more third wireless devices, one or more locations of the one or more second wireless devices, one or more locations of the one or more third wireless devices, one or more signaling priorities associated with the one or more reports, one or more source identifiers of the one or more second wireless devices, one or more indications of when the one or more reports were received at the first wireless device (e.g., a timestamp or time domain reference unit, such as a time slot), or one or more indications of when the one or more reports were generated at the one or more second wireless devices (e.g., a timestamp or time domain reference unit, such as a time slot).

[0076] In various aspects, an indication of channel quality between a first wireless device and one or more second wireless devices may be measured from a transmission carrying a coordination information report. In some cases, the highest ranking may be assigned to a coordination information report associated with a transmission having the strongest or best channel condition (e.g., highest RSRP) as measured by a UE that receives the coordination information. The indication of channel quality may include a reference signal received power (RSRP), a channel quality indicator, a signal-to-noise ratio (SNR), a signal-to-interference plus noise ratio (SINR), a signal-to-noise plus distortion ratio (SNDR), and / or a received signal strength indicator (RSSI). Reference Figure 6, assuming that the third UE 120c measures that the transmission from the first UE 120a has a higher RSRP than the transmission from the second UE 120b. If the coordination information reports are assigned a ranking based on the channel quality of the coordination information transmission, the coordination information report from the first UE 120a may be assigned a higher ranking than the coordination information report from the second UE 120b.

[0077] In various aspects, the highest ranking with respect to distance may be assigned to the coordination report associated with the smallest distance. In various aspects, the distance may be derived from the location of the target UE and / or the UE generating the coordination information. Figure 6 , assuming that the first UE 120a is closer to the third UE 120c than the second UE 120b, and the second UE 120b is closer to the target UE 120d than the first UE 120a. If the ranking is assigned to the coordination information report according to the distance between the UE receiving the coordination information and the UE generating the coordination information, the coordination information report from the first UE 120a may be assigned a higher ranking than the coordination information report from the second UE 120b. If the ranking is assigned to the coordination report according to the distance between the UE generating the coordination information and the target UE for transmission, the coordination information report from the second UE 120b may be assigned a higher ranking than the coordination information report from the first UE 120a.

[0078] In various aspects, the highest ranking with respect to the priority-based ranking may be assigned to the coordination information report associated with the highest priority. Figure 6 , assuming that the priority of the coordination information from the first UE 120a is higher than the priority of the coordination information from the second UE 120b. If the ranking is assigned to the coordination information report according to the signaled priority, the coordination information report from the first UE 120a may be assigned a higher ranking than the coordination information report from the second UE 120b.

[0079] In various aspects, the source identifier may indicate the type of wireless device that generated the coordination information report, and the coordination information reports may be ranked based on certain types of wireless devices. Figure 4A Coordination information associated with an RSU) may be given priority over coordination information from other types of wireless devices (such as vehicles or mobile phones). Figure 6 , assuming that the source identifier of the first UE 120a indicates that the first UE 120a is a roadside unit, and the source identifier of the second UE 120b indicates that the second UE 120b is a vehicle. In this example, the coordination information report from the first UE 120a may be assigned a higher ranking than the coordination information report from the second UE 120b.

[0080] In various aspects, the highest ranking with respect to the time-based ranking may be assigned to the coordination report associated with the shortest time period, for example, as indicated by a timestamp or a time-domain reference unit such as a time slot. Figure 6 , assuming that the third UE 120c receives the coordination information report from the first UE 120a before the coordination information report from the second UE 120b, and the second UE 120b generates its coordination information before the first UE 120b. If the coordination information reports are assigned ranks based on when the coordination information is received, the coordination information report from the first UE 120a may be assigned a higher rank than the coordination information report from the second UE 120b. If the coordination information reports are assigned ranks based on when the coordination information is generated, the coordination information report from the second UE 120b may be assigned a higher rank than the coordination information report from the first UE 120a.

[0081] In various aspects, the coordination information report may be assigned a ranking based on the type of transmission to the target UE. For example, one or more rankings may be assigned at 804 based on whether the communication with one or more third wireless devices at 808 is a unicast, multicast, or broadcast communication. As an example, for a unicast transmission to a target UE, the coordination information report may be ranked based on the distance between the UE generating the coordination information and the target UE for transmission or the source identifier of the target UE. For a multicast or broadcast transmission to (all) target UEs, the coordination information report may be ranked based on the distance between the UE receiving the coordination information and the UE generating the coordination information. In other words, the type of ranking (channel condition, distance, location, priority, source identifier, or time-based) may be selected based on the type of transmission to the target UE (e.g., unicast, multicast, or broadcast).

[0082] In various aspects, coordination information reports may be assigned rankings based on quality of service (QoS) parameters (or settings) associated with transmissions to the target UE. For example, one or more rankings may be assigned at 802 based on one or more quality of service parameters associated with communications with one or more third wireless devices. As an example, assuming that QoS parameters are set for low latency services (e.g., autonomous vehicle services or augmented reality), coordination information reports may be ranked based on when the coordination information is generated. In other words, the type of ranking (channel condition, distance, location, source identifier, and / or time-based) may be selected based on QoS parameters associated with transmissions to the target UE (e.g., QoS parameters for various services such as conversational voice, conversational video, video, low latency applications, or remote control).

[0083] In various aspects, the UE may select a coordination information report based on a ranking for determining which coordination information is applicable for resource selection. In some cases, the UE may select a coordination information report with a highest ranking for use in a resource selection procedure. That is, the UE may select a single coordination information report for resource selection that has a highest ranking among other reports. For example, operation 800 may include: the first wireless device identifies a report with a highest ranking among the reports based on one or more rankings, and determining one or more resources at 806 may include: the first wireless device determines the one or more resources based at least in part on the report with the highest ranking.

[0084] In some cases, the UE may select a subset of ranked coordination information reports for use in a resource selection procedure. For example, operation 800 may include: the first wireless device identifying a subset of reports based on one or more rankings, wherein the subset of the one or more reports may include a plurality of reports, and determining one or more resources at 806 may include: the first wireless device determining the one or more resources based at least in part on the subset of the one or more reports.

[0085] In some cases, the UE may select all coordination information reports for resource selection.For example, determining the one or more resources at 806 may include the first wireless device determining the one or more resources based at least in part on all reports.

[0086] In various aspects, if multiple coordination information reports are selected, a union or combination of the coordination information may be used for resource selection. For example, operation 800 may include the first wireless device identifying a subset of the one or more reports, such as based on a ranking, wherein the subset of the one or more reports includes multiple reports. The first wireless device may combine the coordination information in the subset of the one or more reports. Determining one or more resources at 806 may include the first wireless device determining the one or more resources based at least in part on the combined coordination information.

[0087] The combined coordination information may include all coordination indicated in the identified reports. For example, operation 800 may include the first wireless device combining coordination information in one or more reports, wherein the one or more reports include a plurality of reports. Determining the one or more resources at 806 may include the first wireless device determining the one or more resources based at least in part on the combined coordination information.

[0088] In certain aspects, for example, if a value or a combination of values ​​is equal to, greater than, or less than a particular threshold, some of the coordination information in the coordination information may be discarded from all coordination information reports or a subset of the coordination information reports. For example, operation 800 may include: the first wireless device identifies a subset of the one or more reports, wherein the subset of the one or more reports includes multiple reports. The first wireless device may select the coordination information in the subset of the one or more reports based on one or more thresholds. As an example, if the coordination information is equal to, less than, or greater than a particular RSRP value, a particular distance, a particular priority, a particular source identifier, or a particular time period, the first wireless device may select the coordination information in the subset of reports. Determining one or more resources at 806 may include: the first wireless device determines the one or more resources based at least in part on the selected coordination information.

[0089] In various aspects, some of the coordination information may be dropped from all coordination information reports. For example, operation 800 may include: the first wireless device selecting the coordination information in the one or more reports based on one or more thresholds, and determining the one or more resources at 806 may include: the first wireless device determining the one or more resources based at least in part on the selected coordination information.

[0090] In various aspects, the UE may use coordination information and sensing information for resource selection. In some cases, the UE may prioritize coordination information over sensing information, or vice versa. The UE may select to prioritize coordination information or sensing information based on the ranking of coordination information described herein. In other words, the UE may assign rankings to sensing information, for example, based on channel conditions, distance, priority, source identifier, and / or time, and the UE may select coordination information and sensing information based on these rankings. For example, operation 800 may include: a first wireless device monitors signals from one or more second wireless devices via candidate resources, and generates sensing information based on the monitored signals. The first wireless device may assign a ranking to the sensing information, for example, a ranking based on channel conditions, distance, priority, source identifier, or time as described herein for coordination information. Determining one or more resources at 806 may include: the first wireless device determines the one or more resources based at least in part on one or more rankings assigned to one or more reports and the ranking of the sensing information.

[0091] In some cases, if coordination information is received from a target UE when a unicast transmission is sent to the target UE, the UE may prioritize the coordination information. That is, if specific coordination information is received from a target UE to which the UE will transmit a unicast transmission at 808, the UE may prioritize the coordination information over the sensing information. With respect to operation 800, determining the one or more resources at 806 may include: in the event that the communication with the one or more third wireless devices at 808 is a communication with one of the one or more second wireless devices via unicast communication, the first wireless device prioritizes the report received from the one of the one or more second wireless devices over the sensing information.

[0092] In certain aspects, the UE may prioritize coordination information based on half-duplex communication. That is, in a situation where the UE misses a sensing window due to overlapping transmission (e.g., scheduled downlink, uplink, or sidelink transmission), the UE may supplement the missed sensing information with coordination information. For example, operation 800 may include: the first wireless device selects coordination information to supplement sensing information due to half-duplex communication among one or more reports. The coordination information to supplement sensing information due to half-duplex communication may be coordination information to complete the missed sensing information due to overlapping transmission with the sensing window. Determining one or more resources at 806 may include: the first wireless device determines the one or more resources based at least in part on the selected coordination information and sensing information.

[0093] In some aspects, the UE may use coordination information when sensing information is missed with respect to a given resource. The sensing information may be missed due to half-duplex communication and / or due to a decoding error at the UE. For example, the UE may not be able to successfully decode a control portion (e.g., SCI) or a data portion of a resource in a sensing window, and thus, sensing information associated with the resource may be considered missed. In some cases, when sensing information is missed with respect to a given resource, the UE may prioritize coordination information associated with the given resource. As an example, operation 800 may include: the first wireless device selects coordination information that is missed from the sensing information among one or more reports, and determining one or more resources at 806 may include: the first wireless device determines the one or more resources based at least in part on the selected coordination information and the sensing information.

[0094] In some aspects, the UE may use coordination information when the sensing information conflicts with the sensing information about a given resource. A conflict between the coordination information and the sensing information may occur when the sensing information about a given resource is different from the coordination information about the particular resource. For example, a conflict between the coordination information and the sensing information may occur when the sensing information indicates that the resource is unavailable and the coordination information indicates that the resource is available, or vice versa. In some cases, when there is a conflict between the coordination information and the sensing information, the UE may prioritize the coordination information over the sensing information. In other cases, when there is a conflict between the coordination information and the sensing information, the UE may prioritize the sensing information over the coordination information. As an example, operation 800 may include: the first wireless device selects coordination information that conflicts with the sensing information from one or more reports. Determining one or more resources at 806 may include: the first wireless device determines the one or more resources based at least in part on the selected coordination information and the sensing information.

[0095] In certain aspects, when using coordination information with respect to thresholds for sensing information, the UE may apply different or separate threshold(s) in the resource selection procedure. As an example, the UE may use an RSRP threshold separate from RSRP measurements made at the UE for candidate resources in a resource selection window for RSRP measurements indicated in the coordination information. For example, determining the one or more resources at 806 may include: the first wireless device determining the one or more resources based at least in part on separate thresholds being applied to the coordination information and the sensing information.

[0096] In some aspects, the coordination information may include various information associated with the candidate resources and / or various information associated with the UE generating the coordination information. In some cases, at least one of the reports received at 802 may include an indication of which of the candidate resources are available, an indication of which of the candidate resources are unavailable, an indication of a set of resources to be used for communication, an indication of a set of resources to avoid for communication, an indication of conflict reservation, or a combination thereof. In some aspects, at least one of the reports received at 802 may include: a reference signal received power corresponding to at least one of the candidate resources, a transmission priority corresponding to at least one of the candidate resources, a time domain reference point corresponding to at least one of the candidate resources (e.g., a specific time slot), location information corresponding to at least one of the candidate resources (e.g., time-frequency domain information), or a combination thereof. In various aspects, at least one of the reports received at 802 may include a location of at least one of the second wireless devices, a priority associated with the report, an indication of when the report was generated at the at least one of the second wireless devices, or a combination thereof.

[0097] Fig. 9 The description may include instructions configured to perform operations for the techniques disclosed herein (such as Fig. 9 900 (e.g., UE 120a, RSU, or vehicle) includes various components (e.g., corresponding to means-plus-function components) of the operations explained in the . The communication device 900 includes a processing system 902 coupled to a transceiver 908 (e.g., a transmitter and / or a receiver). The transceiver 908 is configured to transmit and receive signals (such as the various signals described herein) for the communication device 900 via an antenna 910. The processing system 902 may be configured to perform processing functions for the communication device 900, including processing signals received and / or to be transmitted by the communication device 900.

[0098] The processing system 902 includes a processor 904 coupled to a computer readable medium / memory 912 via a bus 906. In some aspects, the computer readable medium / memory 912 is configured to store instructions (e.g., computer executable code) that, when executed by the processor 904, cause the processor 904 to perform Fig. 9 912 or other operations for performing the various techniques for combining coordination information discussed herein. In some aspects, the computer-readable medium / memory 912 stores code 914 for receiving, code 916 for assigning, code 918 for determining, and / or code 920 for communicating (which may include code for receiving and / or code for transmitting). In some aspects, the processor 904 has a circuit system configured to implement the code stored in the computer-readable medium / memory 912. The processor 904 includes a circuit system 924 for receiving, a circuit system 926 for assigning, a circuit system 928 for determining, and / or a circuit system 930 for communicating (which may include a circuit system for receiving and / or a circuit system for transmitting).

[0099] Example aspects

The terms "network" and "system" are often used interchangeably. A CDMA network may implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, and the like. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network may implement radio technologies such as Global System for Mobile Communications (GSM). OFDMA networks can implement radio technologies such as NR (e.g., 5G RA), Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDMA, etc. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). LTE and LTE-A are versions of UMTS that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). NR is an emerging wireless communication technology under development.

[0126] In 3GPP, the term "cell" may refer to the coverage area of ​​a B node (NB) and / or a NB subsystem serving the coverage area, depending on the context in which the term is used. In NR systems, the terms "cell" and BS, next-generation B node (gNB or g B node), access point (AP), distributed unit (DU), carrier, or transmission reception point (TRP) may be used interchangeably. The BS may provide communication coverage for macro cells, pico cells, femto cells, and / or other types of cells. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in a residence, etc.). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS.

[0127] UE may also be referred to as a mobile station, terminal, access terminal, subscriber unit, station, customer premises equipment (CPE), cellular phone, smart phone, personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet computer, camera, gaming device, netbook, smartbook, ultrabook, appliance, medical device or medical equipment, biometric sensor / device, wearable device (such as smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music device, video device, satellite radio, etc.), transportation component or sensor, smart meter / sensor, industrial manufacturing equipment, global positioning system device, or any other suitable device configured to communicate via wireless or wired medium. Some UEs may be considered machine type communication (MTC) devices or evolved MTC (eMTC) devices. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a BS, another device (e.g., a remote device), or some other entity. A wireless node can provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered Internet of Things (IoT) devices, which may be narrowband IoT (NB-IoT) devices. Some UEs may be vehicles, such as cars, trucks, airplanes, ships, unmanned aerial vehicles, etc.

[0128] In some examples, access to the air interface may be scheduled. A scheduling entity (e.g., BS) allocates resources for communication between some or all devices and equipment within its service area or cell. A scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, subordinate entities utilize resources allocated by the scheduling entity. A base station is not the only entity that can be used as a scheduling entity. In some examples, a UE may act as a scheduling entity, and may schedule resources for one or more subordinate entities (e.g., one or more other UEs), and other UEs may utilize resources scheduled by the UE for wireless communication. In some examples, a UE may act as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In a mesh network example, UEs may communicate directly with each other in addition to communicating with a scheduling entity.

[0129] Each method disclosed herein includes one or more steps or actions for implementing the method. These method steps and / or actions can be interchangeable with each other without departing from the scope of the claims. In other words, unless a specific order of steps or actions is specified, the order and / or use of specific steps and / or actions can be changed without departing from the scope of the claims.

[0130] As used herein, a phrase referring to "at least one of" a list of items refers to any combination of those items, including single members. As an example, "at least one of a, b, or c" is intended to cover: a, b, c, ab, ac, bc, and abc, as well as any combination with multiple identical elements (e.g., aa, aaa, aab, aac, abb, acc, bb, bbb, bbc, cc, and ccc, or any other ordering of a, b, and c).

[0131] As used herein, the term "determining" encompasses a wide variety of actions. For example, "determining" may include calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, a database, or another data structure), ascertaining, and the like. Also, "determining" may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and the like. Also, "determining" may include resolving, selecting, choosing, establishing, and the like.

[0132] The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be easily understood by those skilled in the art, and the universal principles defined herein can be applied to other aspects. Thus, the claims are not intended to be limited to the various aspects shown herein, but should be granted the full scope consistent with the language of the claims, wherein the singular reference to the element is not intended to mean "there is and only one" (unless specifically stated) but "one or more". Unless otherwise specifically stated, the term "some / some" refers to one or more. The elements of the various aspects described throughout this disclosure are all structural and functional equivalents currently or hereafter known to those of ordinary skill in the art and are expressly incorporated herein by reference, and are intended to be covered by the claims. In addition, nothing disclosed herein is intended to be donated to the public, regardless of whether such disclosure is explicitly recorded in the claims. Any element of the claim should not be interpreted under the provisions of 35 U.S.C. § 112 (f), unless the element is explicitly stated using the phrase "device for..." or in the case of a method claim, the element is stated using the phrase "step for...".

[0133] The various operations of the methods described above may be performed by any suitable device capable of performing the corresponding functions. These devices may include various hardware and / or software components and / or modules, including but not limited to circuits, application specific integrated circuits (ASICs), or processors. Generally, where there are operations illustrated in the accompanying drawings, these operations may have corresponding paired device-plus-function components with similar numbers.

[0134] The various illustrative logical blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or executed with a general purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device (PLD), discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices, for example, a combination of a DSP and a microprocessor, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration.

[0135] If implemented in hardware, an example hardware configuration may include a processing system in a wireless node. The processing system may be implemented using a bus architecture. Depending on the specific application and overall design constraints of the processing system, the bus may include any number of interconnecting buses and bridges. The bus may link together various circuits including a processor, a machine-readable medium, and a bus interface. The bus interface may be used to connect a network adapter, etc., to the processing system via the bus. The network adapter may be used to implement the signal processing functions of the PHY layer. In a user terminal (see Figure 1 ), a user interface (e.g., a keypad, display, mouse, joystick, etc.) may also be connected to the bus. The bus may also link various other circuits (such as timing sources, peripherals, voltage regulators, power management circuits, etc.), which are well known in the art and therefore will not be described in detail. The processor may be implemented with one or more general and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuit systems capable of executing software. Those skilled in the art will recognize how to best implement the functionality described with respect to the processing system, depending on the specific application and the overall design constraints imposed on the overall network or system.

[0136] If implemented in software, each function may be stored on or transmitted by a computer-readable medium as one or more instructions or codes. Software should be broadly interpreted to mean instructions, data, or any combination thereof, whether referred to as software, firmware, middleware, microcode, hardware description language, or other. Computer-readable media include both computer storage media and communication media, which include any media that facilitate the transfer of computer programs from one place to another. The processor may be responsible for managing the bus and general processing, including executing software modules stored on a machine-readable storage medium. A computer-readable storage medium may be coupled to a processor so that the processor can read and write information from / to the storage medium. In an alternative, a storage medium may be integrated into a processor. As an example, a machine-readable medium may include a transmission line, a carrier modulated by data, and / or a computer-readable storage medium having instructions stored thereon that is separated from a wireless node, all of which may be accessed by a processor through a bus interface. Alternatively or additionally, a machine-readable medium or any part thereof may be integrated into a processor, such as a cache and / or a general register file, which may be the case. As an example, examples of machine-readable storage media may include RAM (random access memory), flash memory, ROM (read only memory), PROM (programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory), registers, magnetic disks, optical disks, hard drives, or any other suitable storage media, or any combination thereof. Machine-readable media may be implemented in a computer program product.

[0137] A software module may include a single instruction, or many instructions, and may be distributed over several different code segments, between different programs, and across multiple storage media. A computer-readable medium may include multiple software modules. These software modules include instructions that cause a processing system to perform various functions when executed by an apparatus such as a processor. These software modules may include a transmission module and a reception module. Each software module may reside in a single storage device or may be distributed across multiple storage devices. As an example, when a triggering event occurs, a software module may be loaded into a RAM from a hard drive. During the execution of a software module, a processor may load some instructions into a cache to increase access speed. One or more cache lines may then be loaded into a general register file for execution by the processor. When describing the functionality of a software module as described below, it will be understood that such functionality is implemented by the processor when the processor executes instructions from the software module.

[0138] Likewise, any connection is properly termed a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technology (such as infrared (IR), radio, and microwave), then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technology (such as infrared, radio, and microwave) is included in the definition of medium. Disk and disc, as used herein, include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk, and Disks, where disks often reproduce data magnetically, and discs reproduce data optically with lasers. Thus, in some aspects, computer-readable media may include non-transitory computer-readable media (e.g., tangible media). Additionally, for other aspects, computer-readable media may include transient computer-readable media (e.g., signals). Combinations of the above should also be included within the scope of computer-readable media.

[0139] Thus, certain aspects may include a computer program product for performing the operations presented herein. For example, such a computer program product may include a computer-readable medium having stored (and / or encoded) thereon instructions that can be executed by one or more processors to perform the operations described herein, such as for performing the operations described herein and in Figure 8 Instructions for the operations explained in .

[0140] In addition, it should be appreciated that modules and / or other appropriate means for performing the methods and techniques described herein may be downloaded and / or otherwise obtained by a user terminal and / or base station where applicable. For example, such a device can be coupled to a server to facilitate the transfer of means for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage device (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or a floppy disk, etc.) so that once the storage device is coupled to or provided to a user terminal and / or base station, the device can obtain the various methods. In addition, any other suitable technology suitable for providing the methods and techniques described herein to a device may be utilized.

[0141] It will be understood that the claims are not limited to the precise configuration and components illustrated above. Various changes, substitutions and variations may be made in the arrangement, operation and details of the methods and apparatus described above without departing from the scope of the claims.
