[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Application No. 17 / 223,987, filed on April 6, 2021, which claims the benefit and priority of U.S. Provisional Patent Application No. 63 / 011,898, filed on April 17, 2020, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate to wireless communications, and more particularly, aspects of the present disclosure relate to techniques for dynamically controlling sidelink resources in a communication network. Background Art

[0004] 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 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) systems, Advanced LTE (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, etc.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at a city, country, region, and even global level. New radio (e.g., 5G NR) is an example of an emerging telecommunication standard. NR is an enhancement set to the LTE mobile standard released by 3GPP. NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using OFDMA with cyclic prefix (CP) on the downlink (DL) and on the uplink (UL), thereby better supporting mobile broadband Internet access. To this end, NR supports beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

[0006] However, 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 them. Summary of the invention

[0036] Aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for improved control of sidelink resources (including V2P, P2V, and more generally V2X resources) in a communication network.

[0037] The following description provides an example of improved control of sidelink resources in a communication system, rather than a limitation on the scope, applicability or examples set forth in the claims. Changes may be made in the functions and arrangements of the elements discussed without departing from the scope of the present disclosure. Various processes or components may be omitted, replaced or added to each example as appropriate. For example, the method described may be performed in an order different from the order described, and various steps may be added, omitted or combined. In addition, the features described with respect to some examples may be combined in some other examples. For example, using any number of aspects set forth herein, a device may be implemented or a method may be practiced. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using other structures, functions, or structures and functions other than or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims. The word "exemplary" is used herein to mean "used as an example, instance or illustration". Any aspect described as "exemplary" herein is not necessarily to be interpreted as being preferred or having advantages over other aspects.

[0038] 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, an air interface, etc. Frequency may also be referred to as a carrier, a subcarrier, a frequency channel, a tone, a 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.

[0039] The techniques described herein can be used for various wireless networks and radio technologies. Although various aspects may be described herein using terms commonly associated with 3G, 4G and / or new radio (e.g., 5G NR) wireless technologies, various aspects of the present disclosure can be applied to communication systems based on other generations.

[0040] NR access (e.g., 5G technology) can support various wireless communication services, such as enhanced mobile broadband (eMBB) targeting wide bandwidth (e.g., 80 MHz or higher), millimeter wave (mmW) targeting high carrier frequency (e.g., 24 GHz to 53 GHz or higher), massive machine type communication MTC (mMTC) targeting non-backward compatible MTC technology, and / or mission critical 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 can dynamically configure beam directions. 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 with up to 2 streams per UE can be supported. Aggregation of multiple cells with up to 8 serving cells can be supported.

[0041] Figure 1 An example wireless communication network 100 is shown in which aspects of the present disclosure may be performed. For example, the wireless communication network 100 may be a NR system (e.g., a 5G NR network). Figure 1 As shown in , the wireless communication network 100 may communicate with a core network 132. The core network 132 may communicate with one or more base stations (BSs) 110 and / or user equipments (UEs) 120 in the wireless communication network 100 via one or more interfaces.

[0042] According to certain aspects, BS 110 may be configured to dynamically allocate sidelink resources (such as V2P, P2V, and more generally V2X resources) to UE 120, which in some embodiments may include pedestrian user equipment (PUE) and vehicle user equipment (VUE), as described below with respect to Figure 4A and 4B discussed in more detail. Figure 1 As shown, according to aspects of the present disclosure, BS 110a includes a sidelink resource manager 112 configured to dynamically allocate sidelink resources (such as V2P, P2V, and more generally V2X resources). In some embodiments, the sidelink resource manager 112 may additionally or alternatively be implemented in other network elements (such as a roadside unit (RSU)), as described below with respect to Figure 4A and Figure 4BIn accordance with aspects of the present disclosure, UE 120a includes a sidelink resource manager 122 configured to interact with the network to control the sidelink resources used by UE 120a. In some embodiments, UE 120a may be a pedestrian user equipment (PUE) and a vehicle user equipment (VUE), as described below with respect to Figure 4A and 4B Described in more detail.

[0043] like Figure 1 As shown, the wireless communication network 100 may include multiple BSs 110a-z (each BS is also individually referred to as BS 110 or collectively referred to as BS 110 herein) and other network entities. BS 110 can provide communication coverage for a specific geographic area (sometimes referred to as a "cell"), which can be fixed or can move according to the location of the mobile BS 110. In some examples, BS 110 can be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless communication network 100 through various types of backhaul interfaces (e.g., direct physical connections, wireless connections, virtual networks, etc.) using any suitable transmission network. Figure 1 In the illustrated example, 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.

[0044] BS 110 communicates with UEs 120a-y (each UE is also referred to herein individually as UE 120 or collectively 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 repeater, 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 data and / or other information to a downstream station (e.g., UE 120 or BS 110), or relays transmissions between UEs 120 to facilitate communication between devices.

[0045] The network controller 130 may communicate with a set of BSs 110 and provide coordination and control (e.g., via a backhaul) for these BSs 110. In various aspects, the network controller 130 may communicate with a core network 132 (e.g., a 5G core network (5GC)), which 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.

[0046] Figure 2 1 shows a BS 110a and a UE 120a (eg, Figure 1 Example components of a wireless communication network 100).

[0047] At BS 110a, transmit processor 220 may receive data from data source 212 and control information from controller / processor 240. Control information may be used 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. Data may be used 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. MAC-CE may be carried in a shared channel (e.g., a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical sidelink shared channel (PSSCH)).

[0048] The processor 220 may process (e.g., encode and symbol map) data and control information, respectively, to obtain data symbols and control symbols. 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 (if applicable), and may provide an output symbol stream to a modulator (MOD) 232a-232t. Each modulator 232 may process a corresponding 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. Downlink signals from modulators 232a-232t may be transmitted via antennas 234a-234t, respectively.

[0049] At UE 120a, antennas 252a-252r can receive downlink signals from BS 110a and can provide received signals to demodulators (DEMODs) 254a-254r in the transceiver, respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the corresponding received signal to obtain input samples. Each demodulator can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain received symbols from all demodulators 254a-254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 can process (e.g., demodulate, deinterleave, and decode) the detected symbols, provide decoded data for UE 120a to data sink 260, and provide decoded control information to controller / processor 280.

[0050] 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., for 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 an antenna, processed by a modulator 232, detected by a MIMO detector 236 (if applicable), and further processed by a receive processor 238 to obtain decoded data and control information transmitted by the UE 120a. Receive processor 238 may provide decoded data to a data sink 239 and decoded control information to controller / processor 240 .

[0051] 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.

[0052] 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 2 As shown, the controller / processor 240 of the BS 110a has a sidelink resource manager 241 configured to dynamically allocate sidelink resources (such as V2P, P2V, and more generally V2X resources) in accordance with various aspects described herein. Figure 2 As shown, according to aspects described herein, the controller / processor 280 of UE 120a has a sidelink resource manager 281, which is configured to interact with the network (e.g., BS 110a) to control the sidelink resources used by UE 120a. Although shown at the controller / processor, other components of UE 120a can be used to perform the operations described herein.

[0053] 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 multiplexing (TDD). OFDM and single carrier frequency division multiplexing (SC-FDM) can divide the system bandwidth into multiple orthogonal subcarriers, which are often referred to as frequency modulation, frequency band, etc. Each subcarrier can be modulated with data. Modulation symbols can be sent using OFDM in the frequency domain and modulated signals can be sent using SC-FDM in the time domain. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers can depend on the system bandwidth. The minimum resource allocation, called a resource block (RB), can be 12 consecutive subcarriers. The system bandwidth can also be divided into subbands. For example, a subband can cover multiple RBs. NR can support a basic subcarrier spacing (SCS) of 15KHz, and other SCSs can be defined with respect to the basic SCS (e.g., 30kHz, 60kHz, 120kHz, 240kHz, etc.).

[0054] Figure 3 300 is a diagram showing an example of a frame format for NR. The transmission timeline for each of the downlink and uplink can be divided into units of radio frames. Each radio frame can have a predetermined duration (e.g., 10ms) and can be divided into 10 subframes with indices 0 to 9, each subframe being 1ms. Each subframe can include a variable number of slots (e.g., 1, 2, 4, 8, 16... slots), depending on the SCS. Each slot can include a variable number of symbol periods (e.g., 7 or 14 symbols), depending on the SCS. An index can be assigned to the symbol period in each slot. A microslot (which can 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 can indicate a link direction (e.g., DL, UL, or flexible) for data transmission, and the link direction of each subframe can be dynamically switched. The link direction can be based on the slot format. Each slot can include DL / UL data and DL / UL control information.

[0055] In NR, synchronization signal blocks (SSBs) are transmitted. In certain aspects, SSBs may be transmitted in bursts, 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). SSBs include PSS, SSS, and two-symbol PBCH. They may be transmitted at fixed time slot locations (such as at Figure 3The SSB is sent in the symbols 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 identification. PBCH carries some basic system information, such as downlink system bandwidth, timing information within the radio frame, SS burst set periodicity, system frame number, etc. SSB can be organized into SS bursts to support beam scanning. The remaining system information, such as remaining minimum system information (RMSI), system information block (SIB), and other system information (OSI) can be sent on the physical downlink shared channel (PDSCH) in certain subframes. For mmWave, SSB can be sent up to sixty-four times, for example, using up to sixty-four different beam directions. Multiple transmissions of SSB are called SS burst sets. SSBs in an SS burst set can be sent in the same frequency region, while SSBs in different SS burst sets can be sent at different frequency regions.

[0056] In some examples, the communication between UE 120 and BS 110 is referred to as an access link. The access link may be provided via a Uu interface. The communication between devices may be referred to as a sidelink.

[0057] In some examples, two or more subordinate entities (e.g., UE 120) can communicate with each other using sidelink signals. Real-world applications of such sidelink communications may include public safety, proximity services, UE to network relay, vehicle to vehicle (V2V) communication, vehicle to pedestrian (V2P) communication, Internet of Everything (IoE) communication, IoT communication, mission-critical mesh networks, and / or various other suitable applications. In general, a sidelink signal may refer to a signal transmitted from one subordinate entity (e.g., UE 120a) to another subordinate entity (e.g., another UE 120) without relaying the communication through a scheduling entity (e.g., UE 120 or BS 110), even if the scheduling entity may be used for scheduling and / or control purposes. In some examples, licensed spectrum may be used to transmit sidelink signals (unlike wireless local area networks that typically use unlicensed spectrum). An example of sidelink communication is PC5, for example, as used in V2V, LTE, and / or NR.

[0058] 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 proximal devices to discover each other. The PSCCH may carry control signaling (such as sidelink resource configurations and other parameters for data transmission), and the PSSCH may carry data transmissions. The PSFCH may carry feedback (such as CSI related to sidelink channel quality).

[0059] Example V2X System

[0060] Figure 4A and Figure 4B A diagrammatic representation of an example V2X system according to some aspects of the present disclosure is shown. Figure 4A and Figure 4B The vehicle shown in may include a vehicle user equipment (VUE) that is configured to communicate with other user equipment (such as a pedestrian user equipment (PUE)) and other network elements (such as a roadside unit (RSU)) via a sidelink channel, and the sidelink channel can be dynamically configured as described herein.

[0061] exist Figure 4A and Figure 4B The V2X system provided in the present invention provides two complementary transmission modes. The first transmission mode (via Figure 4A The second transmission mode (shown by example in FIG. 1 ) involves direct communication between participants that are close to each other in a local area (e.g., also referred to as sidelink communication). Figure 4B ) involves network communication through a network, which can be implemented on a Uu interface (e.g., a wireless communication interface between a radio access network (RAN) and a UE).

[0062] refer to Figure 4A , depicts a V2X system 400 that includes vehicle-to-vehicle (V2V) communications between vehicles 402 and 404 and vehicle-to-pedestrian (V2P) communications between vehicles 402, 404 and a pedestrian user device 414 (e.g., a mobile device such as a smartphone). A first transmission mode allows direct communication between different participants in a given geographic location.

[0063] As shown, the vehicle may have a wireless communication link 406 with a pedestrian (or other individual) (V2P) via the pedestrian's user device 414 via a sidelink (such as via a PC5 interface). Communication between vehicles 402 and 404 may also occur via a PC5 interface 408.

[0064] In a similar manner, V2I communications may occur from vehicle 402 to road network elements 410 (such as traffic lights, signs, or other roadside units) via PC5 interface 412. Figure 4A Each communication link shown in , allows for bidirectional communication between various elements, so that each element can be both a sender and a receiver of information.

[0065] In some embodiments, such as in Figure 4A In some examples, a roadside unit (RSU) may be used for V2X communication, such as V2I communication in this example. In some examples, the RSU may act as a forwarding network element to extend coverage for the UE. In some examples, the RSU may be co-located with the BS or may be independent.

[0066] RSUs can have different classifications. For example, RSUs can be classified into UE-type RSUs and micro Node B-type RSUs. Micro NB-type RSUs have similar functions to macro eNB / gNBs. Micro NB-type RSUs can utilize the Uu interface. UE-type RSUs can be used to meet strict quality of service (QoS) requirements by minimizing conflicts and improving reliability. UE-type RSUs can use centralized resource allocation mechanisms to allow efficient resource utilization. Critical information (e.g., traffic conditions, weather conditions, congestion statistics, sensor data, etc.) can be broadcast to UEs in the coverage area. Repeaters can rebroadcast critical information received from some UEs. UE-type RSUs can be reliable synchronization sources.

[0067] In some embodiments, the V2X system 400 may be a self-managed system implemented without assistance from a network entity. Since no network service interruption occurs during handover operations for a moving vehicle, the self-managed system may achieve improved spectrum efficiency, reduced costs, and increased reliability. The V2X system may be configured to operate in a licensed or unlicensed spectrum, so any vehicle with an equipped system may access a common frequency and share information. Such coordinated / common spectrum operations allow for safe and reliable operation.

[0068] Figure 4BAnother transmission mode for V2X system 450 for communication between vehicle 452 and vehicle 454 through network element 456 is depicted. These network communications may occur through a separate network element, such as a BS (e.g., BS 110a), that sends information to and receives information from vehicles 452 and 454 (e.g., relays information between vehicles 452 and 454). For example, network communications through vehicle-to-network (V2N) links 458 and 410, which are examples of network access links (e.g., via a Uu interface), may be used for long-range communications between vehicles, such as for communicating the presence of a traffic accident a distance ahead along a road or highway. Wireless network element 456 may send other types of communications to the vehicle, such as traffic flow conditions, road hazard warnings, environmental / weather reports, and service station availability, etc. In some embodiments, such data may be obtained from a cloud-based sharing service.

[0069] Improving the efficiency of V2X systems using dynamic sidelink resource allocation

[0070] V2X systems (such as Figure 4A and 4B ) can greatly improve pedestrian safety in various environments (such as urban environments). For example, when a pedestrian is on a collision course with a vehicle, the vehicle can send a communication to the pedestrian (e.g., via the pedestrian's UE) to alert the pedestrian to the upcoming vehicle. Therefore, various standard organizations (e.g., 3GPP) hope to implement communication standards for V2X systems to improve pedestrian safety.

[0071] However, additional functionality in any network communication system requires coordination and control to avoid overburdening network resources. In particular, existing wireless communication systems are already highly utilized, so adding additional features that require additional messaging requires careful consideration to avoid degrading overall network performance.

[0072] For example, V2X resources (such as vehicle-to-pedestrian (V2P) and pedestrian-to-vehicle (P2V) resources) may be needed in certain conditions, but not in other conditions. Therefore, static assignment of V2X resources (such as sidelink pool resources) may result in underutilization of these resources in certain conditions. For example, while an urban environment may be busy with vehicle and pedestrian traffic during daytime hours, the same environment may not be busy during late night / early morning hours. Therefore, the allocation of network resources during these two different sets of conditions does not have to be the same, and in fact would be inefficient if it were the same.

[0073] Accordingly, the present disclosure proposes various methods for dynamically controlling network resources, such as sidelink resources used in a V2X system, which improve the capabilities of the network without negatively impacting the performance of the network.

[0074] Example Dynamic Control of Sidelink Resource Pools for V2X Messaging

[0075] Aspects of the present disclosure provide systems and methods for dynamically controlling sidelink resources for V2X messaging, such as P2V and V2P messaging.

[0076] Figure 5A and 5B Examples of dynamically activating and deactivating V2X resources such as sidelink resources (including P2V / V2P resource pools) are depicted.

[0077] Specifically, Figure 5A A call flow diagram illustrating example operations 500 for wireless communications in accordance with certain aspects of the present disclosure is depicted. Operations 500 may be performed, for example, at a network element such as a base station (e.g., Figure 1 BS 110a) or RSU (e.g., Figure 4A 410)) and UE (eg, Figure 1 UE 120a or UE 120a in the wireless communication network 100 Figure 4A 414) and / or VUE (e.g., Figure 4A In addition, operation 500 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, in operation 500, the transmission and reception of signals by the UE and the network element (e.g., BS or RSU) can be performed, for example, through one or more antennas (e.g., Figure 2 This can be achieved by using antennas 234a and 252a).

[0078] Operations 500 begin at 508 with network element 502 sending a message to user equipment (UE) 504. In some embodiments, UE 504 may be a network element such as Figure 1 and 2 UE 120a in or such as Figure 4A Pedestrian UE of PUE 414 in.

[0079] In this embodiment, the message at step 508 includes a MAC control element (MAC-CE) including a first logical channel ID (LCID1) configured to cause the UE 504 to activate a sidelink resource pool (typically, V2X resources) for P2V and V2P communications. The P2V / V2P sidelink resource pool may be a subset of a common sidelink resource set that may be preconfigured in the UE 504 by the network.

[0080] Operation 500 then proceeds to 510, where the network element 502 sends a message to the vehicle user equipment (VUE) 506. In some embodiments, the VUE 504 may be as described above with respect to Figure 4A and 4B As described with reference to vehicles 402 , 404 , 452 , and 454 .

[0081] In this embodiment, the message at step 510 includes a MAC-CE including a first logical channel ID (LCID1) configured to cause the VUE 506 to activate a sidelink resource pool for P2V and V2P communications. As described above, the P2V / V2P sidelink resource pool may be a subset of a common set of sidelink resources that may be preconfigured in the VUE 506 by the network.

[0082] Operations 500 then proceed to steps 512 and 514 where, in response to the messages at steps 508 and 510, the UE 504 and the VUE 506 activate respective P2V / V2P sidelink resource pools.

[0083] Operations 500 then proceed to steps 516 and 518, where the UE 504 and the VUE 506 directly exchange messages using the P2V / V2P sidelink resource pool activated at steps 512 and 514. For example, the messages at steps 516 and 518 may be regarding the proximity of a pedestrian carrying the UE 504 to a vehicle carrying the VUE 506 and operating near the pedestrian.

[0084] Operations 500 then proceed to steps 520 and 522, where the network element 502 sends messages to the UE 504 and the VUE 506, respectively. In this embodiment, the messages at steps 520 and 522 include a MAC-CE including a second logical channel ID (LCID2) configured to cause the UE 504 and the VUE 506 to deactivate the P2V / V2P sidelink resource pool.

[0085] In this example, the two LCIDs (LCID1 and LCID2) carried in the MAC-CE are configured to activate and deactivate the P2V / V2P side link resource pool (respectively). However, additional LCIDs and other types of control messages can be used to activate and deactivate the P2V / V2P side link resource pool. In some embodiments, various LCIDs can be standardized for activating and deactivating the P2V / V2P side link resource pool, for example, in a 3GPP technical standard section. For example, Tables 6.2.1-1 and 6.2.1-2 of TS 38.321 may include specific LCIDs related to the configuration of side link resources (including the P2V / V2P side link resource pool), as described in this document with respect to this figure and other figures.

[0086] In some embodiments, network element 502 is a base station (e.g., Figure 1 and 2 110a in the BS 110a), and messages 508, 510, 520 and 522 may be, for example, downlink scheduling (DL-SCH) messages for an access link (such as via a Uu air interface), as described above in Figure 4B Alternatively, the network element 502 is a roadside unit (RSU) (e.g., Figure 4A In the case of RSU410 in the example, messages 508, 510, 520 and 522 may be, for example, physical sidelink shared channel (PSSCH) messages of a sidelink (such as via a PC5 air interface).

[0087] Figure 5B An example of selectively activating and deactivating a P2V / V2P sidelink resource pool is depicted. Specifically, during time period 552, the P2V / V2P sidelink resource pool is deactivated. Then, during time period 554, the P2V / V2P sidelink resource pool 558 is activated, such as by Figure 5A Then, during time period 556, the P2V / V2P sidelink resource pool 558 is deactivated, such as by Figure 5A Steps 520-526 in .

[0088] As in Figure 5B As depicted in , the P2V / V2P sidelink resource pool 558 is a subset of the common sidelink resource pool 560 .

[0089] As about Figure 5A Operation 500 in and Figure 5BAs more generally depicted in , network elements may dynamically control activation and deactivation of network resources, such as P2V / V2P sidelink resources (generally, V2X sidelink resources). Thus, operations 500 enable more efficient use of network resources based on conditions (e.g., immediate demand for P2V / V2P sidelink resources). As described above, the P2V / V2P sidelink resource pool may be enabled at certain times of the day based on predicted activity and demand or dynamically enabled based on sensed demand. For example, in the event that the network observes a large number of connections of both UEs and VUEs in an area, the P2V / V2P sidelink resource pool may be activated. It is noted that these are just a few examples and many other examples are possible.

[0090] Fig. 6A and 6B Another example of dynamically configuring V2X resources such as sidelink resources (including P2V / V2P resource pools) is depicted.

[0091] Specifically, Fig. 6A A call flow diagram illustrating example operations 600 for wireless communications in accordance with certain aspects of the present disclosure is depicted. Operations 600 may be performed, for example, at a network element such as a base station (e.g., Figure 1 BS 110a) or RSU (e.g., Figure 4A 410)) and UE (eg, Figure 1 UE 120a or UE 120a in the wireless communication network 100 Figure 4A 414) and / or VUE (e.g., Figure 4A In addition, operation 600 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, in operation 600, the transmission and reception of signals by the UE and the network element (e.g., BS or RSU) can be performed, for example, via one or more antennas (e.g., Figure 2 This can be achieved by using antennas 234a and 252a).

[0092] Operations 600 begin at steps 608 and 610 with network element 602 sending messages to user equipment (UE) 604 and vehicle user equipment (VUE) 606, respectively. In some embodiments, UE 604 may be a network element such as Figure 1 and 2 UE 120a in the UE or such as Figure 4A In some embodiments, the VUE 604 may be a pedestrian UE of the PUE 414 in FIG. Figure 4A and 4BAs described with reference to vehicles 402 , 404 , 452 , and 454 .

[0093] In this embodiment, the messages at steps 608 and 610 include RRC messages including DRX cycle preconfiguration for sidelink resource pools (generally, V2X resources) for P2V and V2P communications of UE 604 and VUE 606, respectively. The P2V / V2P sidelink resource pool may be a subset of a common set of sidelink resources that may be preconfigured in UE 604 and VUE 606 by the network.

[0094] Operation 600 then proceeds to steps 612 and 614, where, in response to the messages at steps 608 and 610, UE 604 and VUE 606 configure respective DRX cycles for their P2V / V2P sidelink resources. For example, UE 604 and VUE 606 may configure the DRX cycle length at steps 612 and 614, respectively.

[0095] Operation 600 then proceeds to steps 616 and 618, where the network element 602 sends a message including a MAC-CE to the UE 604 and the VUE 606, respectively, the MAC-CE including a logical channel ID (LCID) configured to cause the UE 604 and the VUE 606 to update (or reconfigure) their DRX cycles. i ). For example, the LCID may cause the UE 604 and the VUE 606 to extend or shorten their DRX cycles (in other words, adjust the frequency of the DRX period). Note that the LCID in steps 616 and 618 i There can be M predetermined LCIDs i one of , where i∈{1…M), where each LCID i It may be preconfigured so that the receiving device changes its DRX cycle in a prescribed manner. As described above, in some embodiments, each LCID may be standardized, for example, in a 3GPP technical standard section, for selectively changing the P2V / V2P sidelink resource pool DRX characteristics.

[0096] Operation 600 then proceeds to steps 620 and 622, where, in response to the messages at steps 616 and 618, UE 604 and VUE 606 update the respective DRX cycles for their P2V / V2P sidelink resources. As described above, the updated DRX cycle may be longer or shorter than the DRX cycle initially configured at steps 612 and 614, such as in Figure 6B , where the original cycle length w1 is increased to w2 in time periods 654 and 656.

[0097] The operation 600 then proceeds to steps 624 and 626 , where the UE 604 and the VUE 606 directly exchange messages using the P2V / V2P sidelink resource pool according to the DRX cycle updated at steps 620 and 622 .

[0098] In some embodiments, network element 602 is a base station (e.g., Figure 1 and 2 110a in the BS 110a), and messages 616 and 618 may be, for example, downlink scheduling (DL-SCH) messages for an access link (such as via a Uu air interface), as described above in Figure 4B Alternatively, the network element 602 is a roadside unit (RSU) (e.g., Figure 4A In the case of an RSU 410 in FIG. 4 , messages 616 and 618 may be, for example, physical sidelink shared channel (PSSCH) messages of a sidelink (such as via a PC5 air interface).

[0099] Figure 6B An example of selectively updating (or reconfiguring) DRX cycle characteristics for a P2V / V2P sidelink resource pool is depicted. Specifically, during time period 652, the P2V / V2P sidelink resource pool has a DRX cycle length w1. Then, during time periods 654 and 656, the P2V / V2P sidelink resource pool has an updated DRX cycle length w2, which is longer in this example. The update of the DRX cycle for UE 604 and VUE 606 can be as described above in Fig. 6A The process is completed in steps 616-622.

[0100] As in Figure 6B As depicted in , the P2V / V2P sidelink resource pool 658 is a subset of the common sidelink resource pool 660 .

[0101] As about Fig. 6A Operation 600 in and Figure 6B As more generally depicted in , a network element may dynamically control characteristics of network resources, such as a DRX cycle of P2V / V2P sidelink resources (generally, V2X sidelink resources). Thus, operations 600 enable more efficient use of network resources based on conditions (e.g., immediate demand for P2V / V2P sidelink resources).

[0102] For example, the DRX cycle time for P2V / V2P sidelink resources may be changed at certain times of the day based on predicted activity and demand or dynamically based on sensed demand. For example, when the network observes a large number of connections of both UEs and VUEs in an area, the DRX cycle may be shortened so that more P2V / V2P sidelink resources are available in any given time block (such as during time period 652). Alternatively, where the network determines that there is less demand, the DRX cycle may be lengthened so that fewer P2V / V2P sidelink resources are available in any given time block (such as during time periods 654 and 656), thereby saving power in battery-powered mobile devices (such as UE 604) and preserving network physical resources for other functions. Note that these are just a few examples and many other examples are possible.

[0103] Fig. 7A and 7B Another example of dynamically configuring V2X resources such as sidelink resources (including P2V / V2P resource pools) is depicted.

[0104] Specifically, Fig. 7A A call flow diagram illustrating example operations 700 for wireless communications in accordance with certain aspects of the present disclosure is depicted. Operations 700 may be performed, for example, at a network element such as a base station (e.g., Figure 1 BS 110a) or RSU (e.g., Figure 4A 410)) and UE (eg, Figure 1 UE 120a or UE 120a in the wireless communication network 100 Figure 4A 414) and / or VUE (e.g., Figure 4A In addition, operation 700 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, in operation 700, the transmission and reception of signals by the UE and the network element (e.g., BS or RSU) can be performed, for example, via one or more antennas (e.g., Figure 2 This can be achieved by using antennas 234a and 252a).

[0105] Operations 700 begin at 708 and 710 with network element 702 sending messages to user equipment (UE) 704 and vehicle user equipment (VUE) 706, respectively. In some embodiments, UE 704 may be a network element such as Figure 1 and Figure 2 UE 120a in or a UE such as Figure 4A In some embodiments, the VUE 704 may be a pedestrian UE of the PUE 414 in FIG. Figure 4A and Figure 4B As described with reference to vehicles 402 , 404 , 452 , and 454 .

[0106] In this embodiment, the messages at steps 708 and 710 include RRC messages including P2V / V2P sidelink resource pool preconfiguration for sidelink resource pools (generally, V2X resources) for P2V and V2P communications, respectively, for UE 704 and VUE 706. The P2V / V2P sidelink resource pool may be a subset of a common set of sidelink resources that may also be preconfigured in UE 704 and VUE 706 by the network.

[0107] Operations 700 then proceed to steps 712 and 714, where, in response to the messages at steps 708 and 710, UE 704 and VUE 706 configure their respective P2V / V2P sidelink resource pools. For example, UE 704 and VUE 706 may configure an initial set of physical resource blocks, such as Figure 7B A set of physical resource blocks (PRBs) may be defined by the number of consecutive resource blocks (e.g., 2 PRBs) and by a specific time and frequency allocation for each physical resource block (which gives the PRBs a "shape" when plotted with respect to time and frequency).

[0108] Operation 700 then proceeds to steps 716 and 718, where the network element 702 sends messages to the UE 704 and the VUE 706, respectively, the messages including a MAC-CE including a logical channel ID (LCID) configured to cause the UE 704 and the VUE 706 to update (or reconfigure) their respective P2V / V2P sidelink resource pools. i ). For example, the LCID may cause UE 704 and VUE 706 to change the characteristics of their P2V / V2P sidelink resource pools, such as the number of PRBs and / or the shape of the PRBs (with respect to time and frequency allocation). Note that the LCID in steps 716 and 718 i Can be N pre-determined LCIDs i one of , where i∈{1…N), where each LCID i It may be preconfigured so that the receiving device changes its P2V / V2P sidelink resource pool in a prescribed manner. As described above, in some embodiments, individual LCIDs may be standardized, for example, in a 3GPP technical standard section, for selectively changing P2V / V2P sidelink resource pool allocation characteristics.

[0109] Operations 700 then proceed to steps 720 and 722, where, in response to the messages at steps 716 and 718, UE 704 and VUE 706 update the characteristics of their P2V / V2P sidelink resource pools, respectively. As described above, the updated P2V / V2P sidelink resource pools may include more or fewer physical resources and different times and / or frequencies than the P2V / V2P sidelink resource pools configured at steps 712 and 714. For example, as in Figure 7B As depicted in FIG. 7 , the initially configured P2V / V2P sidelink resource pool 758 during period 752 may be modified at steps 720 and 722 to include more physical resources (such as in P2V / V2P sidelink resource pool 762 during periods 754 and 756 ).

[0110] Operations 700 then proceed to steps 724 and 726 where the UE 704 and the VUE 706 exchange messages directly using the P2V / V2P sidelink resource pool according to the characteristics updated at steps 720 and 722 .

[0111] In some embodiments, network element 702 is a base station (e.g., Figure 1 and 2 110a in the BS 110a), and messages 716 and 718 may be, for example, downlink scheduling (DL-SCH) messages for an access link (such as via a Uu air interface), as in Figure 4B Alternatively, the network element 702 is a roadside unit (RSU) (e.g., Figure 4A In the case of an RSU 410 in the example embodiment, messages 716 and 718 may be, for example, physical sidelink shared channel (PSSCH) messages of a sidelink (such as via a PC5 air interface).

[0112] Figure 7B An example of selectively updating (or reconfiguring) physical characteristics for a P2V / V2P sidelink resource pool is depicted. Specifically, during time period 752, the P2V / V2P sidelink resource pool has a time and frequency allocation as depicted at 758. Then, during time periods 754 and 756, the P2V / V2P sidelink resource pool has an updated time and frequency allocation, which in this example is greater in amount than time period 752. The updates to the physical characteristics of the P2V / V2P sidelink resource pool for UE 704 and VUE 706 may be as described above in Fig. 7A The process is completed in steps 716-722.

[0113] As in Figure 7B As depicted in , P2V / V2P sidelink resource pools 758 and 762 are subsets of common sidelink resource pool 760 .

[0114] As about Fig. 7A Operation 700 in and Figure 7B As more generally depicted in FIG. 7 , a network element may dynamically control characteristics of network resources, such as physical resource allocation for P2V / V2P sidelink resources (generally, V2X sidelink resources). Thus, operations 700 enable more efficient use of network resources based on conditions (e.g., immediate demand for P2V / V2P sidelink resources).

[0115] For example, the number of physical P2V / V2P sidelink resources may be changed at certain times of the day based on predicted activity and demand, or may be changed dynamically based on sensed demand. For example, where the network observes a large number of connections of both UEs and VUEs in an area, the number of physical P2V / V2P sidelink resources may be increased to serve the large number of UEs and VUEs that may be interacting. Alternatively, where the network determines that there is less demand, the number of physical P2V / V2P sidelink resources may be reduced, thereby conserving power for battery-powered mobile devices (such as UE 704) and preserving network physical resources for other functions. Note that these are just a few examples, and many other examples are possible.

[0116] Figure 8 Another example of dynamically configuring V2X resources such as sidelink resources (including P2V / V2P resource pools) is depicted.

[0117] Specifically, Figure 8 A call flow diagram illustrating example operations 800 for wireless communications in accordance with certain aspects of the present disclosure is depicted. Operations 800 may be performed, for example, at a network element such as a base station (e.g., Figure 1 BS 110a) or RSU (e.g., Figure 4A 410)) and UE (eg, Figure 1 UE 120a or UE 120a in the wireless communication network 100 Figure 4A 414) and / or VUE (e.g., Figure 4A In addition, operation 800 may be implemented as a processor (e.g., Figure 2 In addition, in operation 800, the transmission and reception of signals by the UE and the network element (e.g., BS or RSU) can be performed, for example, via one or more antennas (e.g., Figure 2 This can be achieved by using antennas 234a and 252a).

[0118] Operations 800 begin at 808 and 810 with network element 802 sending messages to user equipment (UE) 804 and vehicle user equipment (VUE) 806, respectively. In some embodiments, UE 804 may be a network element such as Figure 1 and 2 UE 120a in or such as Figure 4A In some embodiments, the VUE 806 may be a pedestrian UE of the PUE 414 in FIG. Figure 4A and 4B As described with reference to vehicles 402 , 404 , 452 , and 454 .

[0119] In this embodiment, the message at steps 808 and 810 includes a MAC control element (MAC-CE) including a first logical channel ID (LCID1) configured to cause UE 804 and VUE 806 to activate the sidelink resource pool. In some embodiments, the sidelink resource pool may be referred to as a common sidelink resource pool.

[0120] Operations 800 then proceed to steps 812 and 814 where, in response to the messages at steps 808 and 810, the UE 804 and VUE 806 configure their respective sidelink resource pools.

[0121] Operations 800 then proceed to steps 816 and 818, where the network element 802 sends a message including a MAC-CE to the UE 804 and the VUE 806, respectively, the MAC-CE including a second logical channel ID (LCID2) configured to cause the UE 804 and the VUE 806 to activate their P2V / V2P sidelink resource pools. The P2V / V2P sidelink resource pools may be a subset of a common set of sidelink resources, such as the sidelink resource pools activated for the UE 804 and the VUE 806 at steps 812 and 814, respectively.

[0122] Operations 800 then proceed to steps 820 and 822, where, in response to the messages at steps 816 and 818, the UE 804 and VUE 806 configure their respective P2V / V2P sidelink resource pools, such as by activating them and / or configuring their operating parameters (e.g., DRX cycles, time and frequency allocations, etc.).

[0123] Operations 800 then proceed to steps 824 and 826 where the UE 804 and the VUE 806 exchange messages directly using the P2V / V2P sidelink resource pool according to the configuration at steps 820 and 822 .

[0124] The operation 800 then continues with steps 828 and 830, where the network element 802 sends a message including a MAC-CE to the UE 804 and the VUE 806, respectively, the MAC-CE including a third logical channel ID (LCID3) configured to cause the UE 803 and the VUE 806 to deactivate their P2V / V2P sidelink resource pools.

[0125] Operation 800 then proceeds to steps 832 and 834, where, in response to the messages at steps 828 and 830, UE 804 and VUE 806 deactivate their respective P2V / V2P sidelink resource pools. Note that, although the P2V / V2P sidelink resource pools are deactivated in steps 832 and 834, the common sidelink resources are still active. Thus, the network can control the activation and deactivation of a subset of the sidelink resources.

[0126] Operations 800 then proceed to steps 836 and 838, where the network element 802 sends a message including a MAC-CE to the UE 804 and the VUE 806, respectively, the MAC-CE including a fourth logical channel ID (LCID4) configured to cause the UE 804 and the VUE 806 to deactivate their sidelink resource pools.

[0321] Additional Considerations

[0322] The techniques described herein can be used for various wireless communication technologies, such as NR (e.g., 5G NR), 3GPP Long Term Evolution (LTE), Advanced LTE (LTE-A), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are often used interchangeably. A CDMA network can implement radio technologies such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes Wideband CDMA (WCDMA) and other variants of CDMA. cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA network can implement radio technologies such as Global System for Mobile Communications (GSM). An OFDMA network may 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.

[0323] In 3GPP, the term "cell" may refer to the coverage area of ​​a Node B (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 Node B (gNB or gNodeB), access point (AP), distributed unit (DU), carrier or transmit receive point (TRP) may be used interchangeably. BSs may provide communication coverage for macro cells, pico cells, femto cells and / or other types of cells. Macro cells may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs with service subscriptions. Pico cells may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. Femto cells may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cells (e.g., UEs in a closed subscriber group (CSG), UEs for users in a residence, etc.). BSs for macro cells may be referred to as macro BSs. BSs for pico cells may be referred to as pico BSs. A BS for a femto cell may be called a femto BS or a home BS.

[0324] UE may also be referred to as a mobile station, a terminal, an access terminal, a subscriber unit, a station, a customer premises equipment (CPE), a cellular phone, 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 computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, an appliance, a medical device or medical apparatus, a biometric sensor / device, a wearable device (such as a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet, etc.)), an entertainment device (e.g., a music device, a video device, a satellite wireless unit, etc.), a vehicle-mounted component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a 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, for example, connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) or to a network 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.

[0325] In some examples, access to the air interface can be scheduled. The scheduling entity (e.g., BS) allocates resources for communication between some or all devices and apparatuses in its service area or cell. The scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, the subordinate entity utilizes the resources allocated by the scheduling entity. The base station is not the only entity that can be used as a scheduling entity. In some examples, the UE may be used as a scheduling entity, and resources for one or more subordinate entities (e.g., one or more other UEs) may be scheduled, and other UEs may utilize the resources scheduled by the UE for wireless communication. In some examples, the UE may be used as a scheduling entity in a peer-to-peer (P2P) network and / or in a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, the UEs may also communicate directly with each other.

[0326] The method disclosed herein includes one or more steps or actions for implementing the method. Without departing from the scope of the claims, the method steps and / or actions may be interchangeable with each other. In other words, unless a specific order of steps or actions is specified, the order and / or use of specific steps and / or actions may be modified without departing from the scope of the claims.

[0327] 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. For 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 multiples of the same element (e.g., aa, aaa, aab, aac, abb, acc, bb, bbb, bbc, cc, and ccc or any other ordering of a, b, and c).

[0328] As used herein, the term "determining" includes a 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), inferring, and the like. Furthermore, "determining" may include receiving (e.g., receiving information), accessing (e.g., accessing data in a memory), and the like. Furthermore, "determining" may include resolving, selecting, choosing, establishing, and the like.

[0329] The foregoing 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 apparent to those skilled in the art, and the general principles defined herein may be applied to other aspects. Therefore, the claims are not intended to be limited to the aspects shown herein, but are given the full scope consistent with the text of the claims, wherein, unless specifically stated otherwise, reference to an element in the singular form is not intended to mean "one and only one", but "one or more". Unless otherwise explicitly stated, the term "some" refers to one or more. All structural and functional equivalents of the elements of the various aspects described in this disclosure, which are known or will be known to those skilled in the art, are expressly incorporated herein by reference, and are intended to be included by the claims. In addition, there is no disclosure herein that is intended to be dedicated to the public, regardless of whether such disclosure is explicitly recorded in the claims. No claim element is to be interpreted according to the provisions of 35 U.S.C. § 112 (f), unless the element is explicitly recorded using the phrase "unit for...", or in the case of a method claim, the element is recorded using the phrase "step for...".

[0330] The various operations of the methods described above may be performed by any suitable unit capable of performing the corresponding functions. The unit may include various hardware and / or software components and / or modules, including but not limited to: circuits, application specific integrated circuits (ASICs) or processors. Typically, where there are operations shown in the figure, those operations may have corresponding counterpart functional module components with similar numbers.

[0331] The various illustrative logic blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or performed using 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, a combination of one or more microprocessors and a DSP core, or any other such configuration.

[0332] 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 the user terminal 120 (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 further. The processor may be implemented using one or more general and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits that can execute software. Those skilled in the art will recognize that how to best implement the functionality described for the processing system depends on the specific application and the overall design constraints imposed on the entire system.

[0333] If implemented in software, the functions may be stored on or sent via a computer-readable medium as one or more instructions or codes. Whether referred to as software, firmware, middleware, microcode, hardware description language or other terms, software should be broadly interpreted as meaning instructions, data or any combination thereof. Computer-readable media include both computer storage media and communication media, and communication media include any media that facilitates the transfer of computer programs from one place to another. The processor may be responsible for managing the bus and general processing, which includes 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 information from the storage medium and write information to the storage medium. In an alternative, a storage medium may be integrated into a processor. For 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 via a bus interface. Alternatively or in addition, a machine-readable medium or any part thereof may be integrated into a processor, for example, the case may be a cache and / or a general register file. For 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. The machine-readable medium may be embodied in a computer program product.

[0334] A software module may include a single instruction or many instructions, and may be distributed over several different code segments, distributed among different programs, and distributed across multiple storage media. A computer-readable medium may include multiple software modules. A software module includes instructions that, when executed by a device such as a processor, cause a processing system to perform various functions. A software module may include a sending module and a receiving module. Each software module may be located in a single storage device or distributed across multiple storage devices. For example, when a triggering event occurs, a software module may be loaded from a hard drive into a RAM. During the execution of a software module, a processor may load some of the 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 a processor. It will be understood that when the functions of a software module are mentioned below, such functions are implemented by the processor when executing instructions from the software module.

[0335] In addition, 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 technologies (such as infrared (IR), radio and microwave), then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies (such as infrared, radio and microwave) are included in the definition of medium. As used herein, disk and disc include compact disc (CD), laser disc, optical disc, digital versatile disc (DVD), floppy disk and Blu-ray Optical disks, where magnetic disks typically reproduce data magnetically, and optical disks use lasers to reproduce data optically. 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.

[0336] 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 instructions stored (and / or encoded) thereon, the instructions being executable by one or more processors to perform the operations described herein. For example, a computer program product for performing the operations described herein and in Figure 5A-12B The operations are shown in the instructions.

[0337] In addition, it should be appreciated that the modules and / or other appropriate units for performing the methods and techniques described herein can be downloaded and / or otherwise obtained by the user terminal and / or base station where applicable. For example, such a device can be coupled to a server to facilitate the transmission of the units for performing the methods described herein. Alternatively, the various methods described herein can be provided via a storage unit (e.g., RAM, ROM, a physical storage medium such as a compact disc (CD) or a floppy disk, etc.) so that the user terminal and / or base station can obtain the various methods when the storage unit is coupled to or provided to the device. In addition, any other appropriate technology for providing the methods and techniques described herein to the device can be utilized.

[0338] It is to be understood that the claims are not limited to the precise configuration and components shown above.
