Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to U.S. Application No. 17 / 152,616, filed on January 19, 2021, which claims the benefit of and priority to U.S. Provisional Application No. 62 / 964,111, filed on January 21, 2020, which is hereby assigned to the assignee of the present application and is hereby expressly incorporated by reference in its entirety, as if fully set forth below and for all applicable purposes. Technical Field

[0003] Aspects of the present disclosure relate to wireless communications and, more particularly, to techniques for sidelink communications. 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, to name a few.

[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 of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and better integrating with other open standards using OFDMA with cyclic prefix (CP) on downlink (DL) and uplink (UL). 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 increase, 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. Summary of the invention

[0038] Various aspects of the present disclosure provide apparatus, methods, processing systems, and computer-readable media for configuring sidelink (SL) communications and uplink (UL) or downlink (DL) communications. The link between a user equipment (UE) and a base station (BS) for UL or DL ​​communications may also be referred to as a Uu link. In some aspects, the BS may deploy configurations for SL and Uu links, allowing communications on the SL link and the Uu link to overlap in the time domain (e.g., simultaneous SL and Uu link communications). Some aspects of the present disclosure provide conditions that the BS may consider for deploying SL links and Uu links that allow concurrent SL link communications and Uu link communications. If the BS deployment of SL and Uu links does not allow SL and Uu link communications to overlap in the time domain, some aspects provide techniques for handling such scenarios. For example, as described in more detail herein, the UE may discard one of the SL link communications and the Uu link communications based on a priority associated with the communication. The various aspects described herein provide improved communication efficiency by facilitating concurrent communications between UEs and between base stations.

[0039] The following description provides an example of a configuration for concurrent SL communication and UL or DL ​​communication in a communication system, and does not limit the scope, applicability or examples set forth in the claims. Without departing from the scope of the present disclosure, the functions and arrangements of the elements discussed may be changed. Various examples may omit, replace or add various processes or components as appropriate. 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. In addition, the features described with respect 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 a device or method that is practiced using other structures, functions, or structures and functions other than or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present 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 advantageous over other aspects.

[0040] Typically, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific radio access technology (RAT) and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, subcarrier, frequency channel, frequency modulation, subband, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, a 5GNR RAT network can be deployed.

[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).

[0042] like Figure 1 As shown in , the wireless communication network 100 may include several base stations (BSs) 110a-z (each of which is also referred to herein individually as BS110 or collectively as BS110) and other network entities. BS110 may provide communication coverage for a specific geographic area (sometimes referred to as a "cell"), which may be fixed or may be movable based on the location of the mobile BS110. In some examples, BS110 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 through various types of backhaul interfaces (e.g., direct physical connections, wireless connections, virtual networks, etc.) using any suitable transport network. Figure 1In the example shown, 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. BS 110 communicates with user equipment (UE) 120a-y (each of which is also referred to herein as UE 120 individually or collectively as UE 120) in wireless communication network 100. UE 120 (e.g., 120x, 120y, etc.) may be dispersed throughout wireless communication network 100, and each UE 120 may be fixed or mobile.

[0043] According to some aspects, BS 110 and UE 120 may be configured for concurrent SL communication and UL or DL ​​communication. Figure 1 As shown, UE 120a includes a configuration manager 122. The configuration manager 122 may be configured to receive a first configuration for sidelink (SL) communication performed by the UE, receive a second configuration for uplink (UL) or downlink (DL) communication performed by the UE, determine whether the first configuration and the second configuration allow UL or DL ​​communication to overlap with SL communication in the time domain, and perform SL communication or at least one of UL or DL ​​communication based on the determination. In some aspects, the BS 110 may include a configuration manager 112, which is configured to: determine a first configuration for SL communication performed by the UE, determine a second configuration for UL or DL ​​communication performed by the UE, the first configuration and the second configuration being determined to allow UL or DL ​​communication to overlap with SL communication in the time domain, and send the first configuration and the second configuration to the UE.

[0044] 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., BS110a or UE 120r) and sends transmissions of the data and / or other information to a downstream station (e.g., UE 120 or BS110), or relays transmissions between UEs 120 to facilitate communication between devices.

[0045] A network controller 130 may couple to a set of BSs 110 and provide coordination and control for these BSs 110. The network controller 130 may communicate with the BSs 110 via a backhaul. The BSs 110 may also communicate with each other (eg, directly or indirectly) via a wireless or wired backhaul.

[0046] Figure 2 1 and 120a (eg, in the example embodiment of the present invention) that can be used to implement various aspects of the present disclosure. Figure 1 Example components of the wireless communication network 100).

[0047] At BS 110a, a transmit processor 220 may receive data from a data source 212 and control information from a 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. The processor 220 may process (e.g., encode and symbol map) the data and the 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), and a cell-specific reference signal (CRS). A 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 output symbol streams to modulators (MODs) 232a-232t. Each modulator 232 can process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator can further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The downlink signals from modulators 232a-232t can be transmitted via antennas 234a-234t, respectively.

[0048] At UE 120a, antennas 252a-252r can receive downlink signals from BS110a and can provide received signals to demodulators (DEMODs) in transceivers 254a-254r, respectively. Each demodulator 254 can adjust (e.g., filter, amplify, downconvert, and digitize) the respective received signals 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 these received symbols where appropriate, and provide detected symbols. Receive processor 258 can process (e.g., demodulate, deinterleave, and decode) these detected symbols, provide decoded data for UE 120a to data sink 260, and provide decoded control information to controller / processor 280.

[0049] 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 appropriate, further processed by a demodulator in a transceiver 254a-254r (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 transmitted by the UE 120a. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240 .

[0050] 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.

[0051] The controller / processor 280 and / or other processors and modules at the UE 120a may perform or direct the execution of processes for the techniques described herein. Figure 2 As shown, the controller / processor 280 of UE 120a has a configuration manager 243, which can be configured to: receive a first configuration for SL communication performed by the UE, receive a second configuration for UL or DL ​​communication performed by the UE, determine whether the first configuration and the second configuration allow UL or DL ​​communication to overlap with SL communication in the time domain, and perform SL communication or at least one of UL or DL ​​communication based on the determination. In some aspects, the controller / processor 240 may include a configuration manager 241, which is configured to determine a first configuration for SL communication performed by the UE, determine a second configuration for UL or DL ​​communication performed by the UE, the first configuration and the second configuration are determined to allow UL or DL ​​communication to overlap with SL communication in the time domain, and send the first configuration and the second configuration to the UE. Although shown at the controller / processor, other components of UE 120a and BS110a may be used to perform the operations described herein.

[0052] Figure 3A and Figure 3BA diagrammatic representation of an example vehicle-to-everything (V2X) system is shown according to some aspects of the present disclosure. For example, Figure 3A and Figure 3B The UE shown in FIG. 4 may communicate via a sidelink channel and may perform sidelink CSI reporting as described herein.

[0053] Figure 3A and Figure 3B The V2X system provided in provides two complementary transmission modes. Figure 3A The first transmission mode shown as an example in relates to direct communication (e.g. also called sidelink communication) between participants that are close to each other in a local area. Figure 3B The second transmission mode shown as an example in FIG. 1 relates to network communication through a network, which can be implemented through a Uu interface (e.g., a wireless communication interface between a radio access network (RAN) and a UE). As shown, UE 352, 354 can communicate with each other using a side link (SL) 398.

[0054] Reference Figure 3A , shows a V2X system 300 (e.g., including vehicle-to-vehicle (V2V) communications) with two UEs 302, 304 (e.g., vehicles). A first transmission mode allows direct communication between different participants in a given geographic location. As shown, the vehicles are able to have a wireless communication link 306 with an individual (V2P) (e.g., via a UE) via a PC5 interface. Communication between UEs 302 and 304 may also occur via a PC5 interface 308. In a similar manner, communication may be conducted from UE 302 to other highway components (e.g., highway component 310) (such as traffic signals or signs (V2I)) via a PC5 interface 312. With regard to Figure 3A Each communication link shown may enable bidirectional communication between elements, so each element may be a transmitter and receiver of information. The V2X system 300 may be a self-managed system implemented without assistance from a network entity. The self-managed system may achieve improved spectrum efficiency, reduced costs, and increased reliability because no network service interruptions may occur during handover operations of a moving vehicle. 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 operation allows for safe and reliable operation.

[0055] Figure 3BA V2X system 350 is shown for communicating between a UE 352 (e.g., a vehicle) and a UE 354 (e.g., a vehicle) through a network entity 356. These network communications can occur through discrete nodes (such as base stations (e.g., eNBs or gNBs)) that send information to and receive information from (e.g., relay information between) the UEs 352, 354. Network communications through vehicle-to-network (V2N) links (e.g., Uu links 358 and 310) can be used, for example, for long-range communications between vehicles, such as for communicating the presence of a car accident a distance ahead along a road or highway. The nodes can send other types of communications to the vehicles, such as traffic flow conditions, road hazard warnings, environmental / weather reports, and service station availability, among other examples. Such data can be obtained from a cloud-based sharing service.

[0056] In some cases, two or more subordinate entities (e.g., UE) can use sidelink signals to communicate with each other. As described above, V2V and V2X communications are examples of communications that can be sent via sidelinks. Other applications of sidelink communications may include public safety or service announcement communications, communications for proximity services, communications for UE to network relays, device to device (D2D) communications, Internet of Everything (IoE) communications, Internet of Things (IoT) communications, mission-critical mesh communications, and other suitable applications. Typically, a sidelink may refer to a direct link between a subordinate entity (e.g., UE 1) and another subordinate entity (e.g., UE2). Therefore, even if a scheduling entity can be used for scheduling or control purposes, a sidelink may be used to send and receive communications (also referred to herein as "sidelink signals") without relaying communications through a scheduling entity (e.g., BS). In some examples, a licensed spectrum may be used to convey sidelink signals (different from wireless local area networks that typically use unlicensed spectrum).

[0057] 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 proximate 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 channel state information (CSI) related to the sidelink channel quality.

[0058] Example techniques for concurrent communication

[0059] As described herein, two user equipments (UEs) may communicate via a side link (SL), and one or both of the UEs may communicate with the base station via a Uu link (e.g., a link between a UE and a base station (BS)). As used herein, a Uu link generally refers to an uplink (UL) or a downlink (DL). Two UEs may be instructed to transmit via the SL and Uu links at any given time. In this case, the transmissions may conflict (e.g., overlap) at least in the time domain. As used herein, simultaneous (or concurrent) transmissions (Tx) refer to transmissions that at least partially overlap in the time domain, and simultaneous receptions (Rx) refer to receptions that at least partially overlap in the time domain.

[0060] In some cases, SL reception (and transmission) may occur only on semi-static U symbols (e.g., designated uplink symbols), while Uu reception may occur on D symbols (e.g., designated downlink symbols) and flexible symbols (e.g., symbols that can be configured for uplink or downlink). Therefore, in this case, Uu and SL reception may not conflict in time. However, in one or more examples, SL Tx / Rx on flexible symbols may be allowed. In this case, signal reception on Uu and SL may conflict. In addition, for SL transmission, only cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) waveforms may be allowed; however, for Uu TX, both CP-OFDM and discrete Fourier transform (DFT) spreading (DFT-S) may be used.

[0061] In some deployment scenarios, inter-frequency and inter-band operations may be implemented. For example, for a UE with dual transmit (Tx) / receive (Rx) chains, it may be feasible for the UE to support simultaneous transmit / receive for both synchronous and asynchronous scenarios. However, not all combinations of source / target frequency bands are able to support simultaneous transmit / receive for synchronous and asynchronous scenarios.

[0062] In some cases, inter-frequency intra-band synchronous operation may be implemented. For example, it may be feasible for a UE to support intra-band downlink (DL) carrier aggregation (CA) on frequencies supported by a CA serving cell to support simultaneous reception. In addition, it may be feasible for a UE to support intra-band UL CA on frequencies supported by a CA serving cell to support simultaneous transmission. For inter-frequency intra-band asynchronous implementations, it is unclear whether simultaneous TX and / or RX can be supported.

[0063] In some cases, intra-frequency synchronous communication may be implemented. For example, simultaneous reception may be feasible for some UEs, at least if the source / target bandwidths (e.g., for dual connectivity (DC)) are the same and under some conditions. In addition, under some conditions, simultaneous transmission may be feasible for UEs with a single RF chain. For intra-frequency asynchronous implementations, simultaneous reception may also be feasible for UEs with a single RF chain.

[0064] Some aspects of the present disclosure relate to configurations that allow a UE to communicate concurrently using a SL channel and an UL and / or DL ​​channel. The link between the UE and the BS for UL and DL communications may also be referred to as a Uu link. As described in more detail herein, some aspects may be implemented as concurrent RX and / or TX for UEs with both synchronous and asynchronous deployments. Synchronous SL and Uu link communications typically refer to scenarios where the SL and Uu carriers (also referred to as component carriers) are co-located and the time slot boundaries of the SL and Uu links are aligned within a small margin. Asynchronous SL and Uu link communications typically refer to scenarios where the SL and Uu carriers are non-collocated.

[0065] Some aspects of the present disclosure provide configurations for concurrent Tx / Rx communications for various implementations. Various implementations may include configuring SL and Uu bandwidth parts (BWP) on the same carrier, or configuring SL and Uu BWP on different carriers. In the case where SL and Uu BWP are configured on different carriers, the UE may use a single RF chain for Tx / Rx on these carriers (e.g., intra-band contiguous carriers), or the UE may use more than a single RF chain for Tx / Rx on these carriers (e.g., intra-band non-contiguous or inter-band carriers). Depending on the implementation of the SL and Uu links, the BS may configure the SL and Uu links based on one or more conditions that allow communications on the SL and Uu links to overlap. As described in more detail herein, these conditions may include using the same subcarrier spacing for the SL and Uu links, or using the same waveform for the SL or Uu links.

[0066] Figure 4 4 is a flow diagram illustrating example operations 400 for wireless communications in accordance with some aspects of the present disclosure. Operations 400 may be performed, for example, by a BS (eg, such as BS 110a in wireless communication network 100).

[0067] Operation 400 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, the communication may be performed, for example, via one or more antennas (e.g., Figure 2The antenna 234 of the BS implements the transmission and reception of signals by the BS in operation 400. In some aspects, the transmission and / or reception of signals by the BS may be implemented via a bus interface of one or more processors (e.g., the controller / processor 240) that obtain and / or output signals.

[0068] Operations 400 may begin with, at block 405, the BS determining a first configuration for SL communication by the UE, and, at block 410, determining a second configuration for UL or DL ​​communication (e.g., via a Uu link) by the UE. In some aspects, the first configuration and the second configuration may be determined based on one or more conditions to allow UL or DL ​​communication (e.g., Uu link communication) to overlap with SL communication in the time domain on the same or different carriers. At block 415, the BS may send the first configuration and the second configuration to the UE.

[0069] In some aspects, if the bandwidth part (BWP) used for UL or DL ​​communication and SL communication is on the same carrier, a first configuration and a second configuration to be the same subcarrier spacing (SCS) as SL communication can be determined based on one or more conditions to be used for UL or DL ​​communication. In other words, as described herein, SL and Uu BWP can be configured on the same carrier. In this case, in order to allow concurrent SL and Uu link communications, the SL SCS can be configured to be the same as the SCS of the UL BWP on Uu.

[0070] Figure 5 A communication scenario is shown in which a UE performs concurrent transmissions on a SL 398 and a Uu link 358 according to some aspects of the present disclosure. For simultaneous transmissions, one or more conditions may be applied when the SL and Uu BWPs are on the same carrier. For example, the same waveform may be configured for the SL and Uu links. As described herein, the SL may use only OFDM. Therefore, the configuration of the Uu link may also be set to OFDM. Otherwise, as described in more detail herein, the UE may treat the configuration as an error condition, or use priority sorting to discard one of the SL and Uu link communications. In addition, the SL BWP may be configured within the Uu UL BWP. For UEs with multiple radio frequency (RF) chains (also referred to as "chains") or UL multiple-input multiple-output (MIMO) capabilities, one or more of the conditions for concurrent SL and Uu link communications may be relaxed.

[0071] Figure 6 A communication scenario is shown for concurrent reception at a UE on SL 398 and Uu link 358 according to some aspects of the present disclosure. One or more conditions may be applied to configure SL and Uu link communications for simultaneous reception. For example, the same SCS may be configured for Uu link DL BWP and SL BWP.

[0072] In some deployments, the SL and Uu BWPs may be on different CCs and the UE may be configured with a single RF chain. In this case, various conditions may be applied to configure concurrent SL or Uu link communications. For example, one or more conditions may be applied to allow simultaneous transmissions for synchronous communications (e.g., Figure 5 ). These conditions may include configuring the transmit timing via the cell for the SL within a maximum transmit time difference (MTTD) threshold. The MTTD threshold indicates the relative transmit timing difference between the slot timing boundaries of different carriers used for SL and Uu link transmission. In some aspects, the same SCS may be configured for the Uu UL BWP on one carrier and the SL on another carrier. For UEs supporting UL CA with different SCSs in the same band or band combination, this condition may be relaxed to allow the SCSs used for the Uu ULB WP and SL to be different.

[0073] In some aspects, the same uplink waveform may be configured for communications on the SL and Uu links. As described in more detail herein, if the Uu and SL carriers / BWPs are configured with different waveforms, the scheduler should avoid conflicts (e.g., TDM only), or drop rules may be considered.

[0074] In some aspects, CCs configured for SL and Uu link transmissions may be in the same timing advance group (TAG). Carriers in the same TAG may be associated with the same timing advance (TA). In some aspects, CCs configured for SL and Uu link transmissions may be contiguous. In addition, some power control conditions may be considered when configuring SL and Uu link transmissions. For example, the transmit power for Uu UL and SL may be configured to be within a margin (e.g., also referred to herein as a threshold margin), or the average power per physical resource block (PRB) for SL and Uu link transmissions may be aligned across the allocated carriers (e.g., configured to be the same).

[0075] In some aspects, various conditions may be considered when configuring a UE in a manner that allows simultaneous SL and Uu link reception in a synchronization scenario. For example, the configuration may be determined based on the condition that the SCS is the same for both cells used for SL and Uu link reception at the UE. However, this condition may be relaxed for UEs that support DL CA with different SCSs in the same band or band combination. As described in more detail herein, violation of the condition may be considered an error event or handled by prioritization.

[0076] In some aspects, for asynchronous scenarios, SL and Uu BWP on different CCs and for UEs with a single link (e.g., CC is in-band) can be implemented. For example, simultaneous transmission for asynchronous scenarios can be configured for UEs supporting UL CA in the same band or band combination. If concurrent TX / RX is not feasible for a particular UE, the BS should avoid overlap of SL and Uu link communications in the time domain, or the UE can handle such a configuration based on some priority rules defined for dropping one of the SL or Uu link communications.

[0077] In some aspects, the SL and Uu BWPs may be on different CCs, and the UE may be implemented with at least two RF chains (e.g., the different CCs are inter-band). In this case, some conditions may apply to concurrent SL and Uu link communications. Simultaneous transmission / reception may be configured for both synchronous and asynchronous deployments. For simultaneous reception with asynchronous deployment, separation between carrier frequencies may be configured. In other words, the carrier frequencies used for SL and Uu link communications may be separated by frequency bands to reduce interference between the SL and Uu links.

[0078] In some cases, the UE may indicate to the BS its capability of simultaneous transmission / reception. The capability of the UE may be indicated separately for various configuration candidates. For example, the UE may indicate its capability of: whether both the SL and Uu links are configured on frequency range 1 (FR1), whether the SL is configured on FR1 and the Uu link is configured on FR2, and whether the Uu link is configured on FR1 and the SL is configured on FR1. The BS may then consider the UE's capability to handle simultaneous reception / transmission using the SL and Uu links for the specific configuration to be deployed.

[0079] Although some aspects of the present disclosure have described conditions for allowing concurrent communications on the SL link and the Uu link, there are scenarios where the BS may not configure the SL link and the Uu link according to the conditions described herein. For example, for the Uu link, if the discrete Fourier transform (DFT) spread (DFT-S) in the UL is configured, concurrent SL and Uu link communications may not be possible because the SL may only support OFDM. Therefore, the UE may expect to use the SL and Uu links for transmission using non-overlapping time resources. For example, overlap can be avoided by scheduling or time division multiplexing (TDMing). In other words, if the configuration of the SL and Uu links does not meet the conditions for allowing overlap of communications in the SL and Uu links, the UE may treat the overlap of SL and Uu link communications as an error event.

[0080] In some aspects, the UE may consider a prioritization rule for discarding one of the communications on the Uu link and the SL. For example, the prioritization rule may indicate that the Uu link communication has a higher priority than the SL, and vice versa. As another example, the prioritization may be based on the configured priority of the channels on the SL and Uu links, or may be based on the type of channels on each of the SL and Uu links.

[0081] Figure 7 7 is a flow diagram illustrating example operations 700 for wireless communications in accordance with some aspects of the present disclosure. Operations 700 may be performed, for example, by a UE (eg, such as UE 120a in wireless communication network 100).

[0082] Operation 700 may be implemented as a processor on one or more processors (e.g., Figure 2 In addition, the UE may transmit and receive signals in operation 700 by, for example, one or more antennas (e.g., Figure 2 In some aspects, the transmission and / or reception of signals by the UE may be implemented via a bus interface of one or more processors (eg, controller / processor 280) that obtain and / or output signals.

[0083] Operation 700 may begin by receiving a first configuration for SL communication by the UE at block 705, and receiving a second configuration for UL or DL ​​communication by the UE at block 710. At block 715, the UE may determine whether the first configuration and the second configuration allow UL or DL ​​communication to overlap in the time domain with SL communication on the same or different carriers based on one or more conditions, and at block 720, transmit signaling for SL communication or at least one of UL or DL ​​communication based on the determination.

[0084] In some aspects, if the first configuration and the second configuration do not allow UL or DL ​​communication to overlap with SL communication in the time domain, the UE may determine to abandon performing one of SL communication and UL or DL ​​communication. The determination to abandon performing one of SL communication and UL or DL ​​communication may be based on a priority associated with each of the SL communication and the UL or DL ​​communication.

[0085] Fig. 8A804 is a call flow diagram illustrating example operations for SL or Uu communications according to some aspects of the present disclosure. As shown, at block 802, the BS may determine a configuration 804 for SL and Uu links. As described herein, the SL and Uu link configurations may be determined based on one or more conditions to allow Uu link communications to overlap with SL communications in the time domain on the same or different carriers. As shown, the BS may send the configuration 804 to UE 1, and UE 1 may use the configuration 804 for communications 810 with the BS and UE2 using the SL / Uu links.

[0086] In some aspects, as described herein, UE 1 may optionally send an indication of the capability 812 of UE 1 that Uu link communications overlap with SL communications in the time domain. For example, the capability may be indicated separately for different bands, band combinations, Uu link communications and SL communications synchronously, Uu link communications and SL communications asynchronously, or any combination thereof.

[0087] In this case, the BS's determination of configuration 804 at block 802 may be based on the capabilities of UE 1 .

[0088] In some aspects, after receiving the configuration 804, the UE may determine whether the configuration 804 allows the overlap of the SL communication and the Uu link communication in the time domain at block 806. If not allowed, the UE may prioritize one of the SL link communication or the Uu link communication at block 808. For example, if the SL communication has a lower priority than the Uu link communication, the UE 1 may discard (e.g., abandon) one of the Uu link communications.

[0089] Figure 8B Multiple carriers for SL and Uu links are shown in accordance with some aspects of the present disclosure. In some implementations, multiple carriers (e.g., carrier 1 and carrier 2) may be assigned to the same UE to support carrier aggregation. Fig. 8A As described, at block 802, the BS may determine, based on one or more conditions, a SL link configuration and a Uu link configuration that allow Uu link communication to overlap with SL communication in the time domain on the same or different carriers. For example, if the overlapping BWPs for the Uu link and the SL are on the same carrier, the configuration may be determined based on the condition that the same SCS will be used for the Uu link and the SL. Figure 8B At 860, an SCS associated with a plurality of subcarriers (e.g., subcarriers 861, 862, 864, 866) allocated for the SL is shown, and Figure 8BThe SCS associated with a plurality of subcarriers (e.g., subcarriers 871, 872, 874, 876) allocated for the Uu link is shown at 870. As an example, if BWP 850 is used for a Uu link on carrier 1 and BWP 852 is used for a SL on the same carrier 1, the BS may determine the configuration of the SL link and the Uu link such that the SL link and the Uu link use the same SCS, such as Figure 8B As shown in 860 and 870.

[0090] In some cases, the overlapping BWPs for the Uu link and the SL may be on different carriers. For example, BWP 850 may be used for the Uu link on carrier 1, while BWP 854 may be used for the SL on carrier 2. Figure 8B As shown in , a UE (e.g., UE 120) may have a single RF chain (e.g., RF chain 880) or multiple RF chains (e.g., both RF chain 880 and RF chain 882). An RF chain is a cascade of electronic components (e.g., amplifiers, filters, mixers, attenuators, detectors) that facilitate the transmission or reception of signals. If the UE has a single RF chain (e.g., RF chain 880) and the BWPs for the Uu link and SL are on different carriers, the configuration for the Uu link and SL link may be determined based on the conditions described herein (e.g., the same SCS will be used for the Uu link and SL, the same waveform is used for the Uu link and SL, the CCs for the Uu link and SL are continuous, etc.).

[0131] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5GNR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as the "below 6 GHz" band in various documents and articles. Similar naming issues sometimes arise with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in literature and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0132] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands of these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4A or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0133] In view of the above, unless otherwise specifically stated, it should be understood that the term "below 6 GHz" and the like (if used herein) can broadly refer to frequencies that can be less than 6 GHz, can be within FR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like (if used herein) can broadly refer to frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-A or FR4-1 and / or FR5, or can be within the EHF band.

[0136] In view of the above, unless otherwise specifically stated, it should be understood that the term "below 6 GHz" and the like (if used herein) can broadly represent frequencies that can be less than 6 GHz, can be within fR1, or can include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that the term "millimeter wave" and the like (if used herein) can broadly represent frequencies that can include mid-band frequencies, can be within FR2, FR4, FR4-A or FR4-1 and / or FR5, or can be within the EHF band.

[0137] 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 (SCFDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and other networks. The terms "network" and "system" are generally used interchangeably. A CDMA network can 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 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. 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.

[0138] The technology described herein can be used for the wireless networks and radio technologies mentioned above and other wireless networks and radio technologies. For the sake of clarity, although the terms commonly associated with 3G, 4G and / or 5G wireless technologies may be used herein to describe various aspects, various aspects of the present disclosure can be applied to communication systems based on other generations.

[0139] In 3GPP, the term "cell" can 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) can be used interchangeably. The BS can provide communication coverage for macro cells, pico cells, femto cells and / or other types of cells. A macro cell can cover a relatively large geographic area (e.g., a radius of several thousand meters) and can allow unrestricted access by UEs with service subscriptions. A pico cell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femto cell can cover a relatively small geographic area (e.g., a home) and can allow restricted access by UEs with associations with femto cells (e.g., UEs in a closed subscriber group (CSG), UEs of users in a home, 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 called a femto BS or a home BS.

[0140] 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.), vehicle 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 as 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. that 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 (e.g., a wide area network such as the Internet or a cellular 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.

[0141] Some wireless networks (e.g., LTE) utilize orthogonal frequency division multiplexing (OFDM) on the downlink and single carrier frequency division multiplexing (SC-FDM) on the uplink. OFDM and SC-FDM divide the system bandwidth into multiple (K) orthogonal subcarriers, which are also commonly referred to as tones, bins, etc. Each subcarrier can be modulated with data. Typically, modulation symbols are sent in the frequency domain using OFDM, and modulation symbols are sent in the time domain using SC-FDM. The spacing between adjacent subcarriers can be fixed, and the total number of subcarriers (K) can depend on the system bandwidth. For example, the spacing of the subcarriers can be 15kHz, and the minimum resource allocation (called a "resource block" (RB)) can be 12 subcarriers (or 180kHz). Therefore, for system bandwidths of 1.25, 2.5, 5, 10, or 20 megahertz (MHz), the nominal fast Fourier transform (FFT) size can be equal to 128, 256, 512, 1024, or 2048, respectively. The system bandwidth may also be partitioned into subbands. For example, a subband may cover 1.08 MHz (e.g., 6 RBs), and there may be 1, 2, 4, 8, or 16 subbands for system bandwidths of 1.25, 2.5, 5, 10, or 20 MHz, respectively. In LTE, the basic transmission time interval (TTI) or packet duration is a 1 ms subframe.

[0142] NR can utilize OFDM with CP on both the uplink and downlink, and includes support for half-duplex operation using TDD. In NR, the subframe is still 1ms, but the basic TTI is called a time slot. Depending on the subcarrier spacing, the subframe contains a variable number of time slots (e.g., 1, 2, 4, 8, 16, ... time slots). NR RB is 12 continuous frequency subcarriers. NR can support a basic subcarrier spacing of 15kHz, and other subcarrier spacings can be defined with respect to the basic subcarrier spacing, such as 30kHz, 60kHz, 120kHz, 240kHz, etc. Symbol and time slot lengths scale with subcarrier spacing. The CP length also depends on the subcarrier spacing. Beamforming can be supported, and the beam direction can be dynamically configured. MIMO transmission with precoding can also be supported. In some examples, the MIMO configuration in DL can support up to 8 transmit antennas, with multi-layer DL transmissions up to 8 streams and up to 2 streams per UE. In some examples, multi-layer transmissions with up to 2 streams per UE can be supported. Aggregation of multiple cells with up to 8 serving cells can be supported.

[0143] 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 equipment within its service area or cell. The scheduling entity may be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communications, subordinate entities utilize 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, a UE may be used 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 the resources scheduled by the UE for wireless communication. In some examples, a UE may be used as a scheduling entity in a peer-to-peer (P2P) network and / or a mesh network. In the mesh network example, in addition to communicating with the scheduling entity, UEs may also communicate directly with each other.

[0144] In some examples, two or more subordinate entities (e.g., UEs) can 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 grids, and / or various other suitable applications. In general, a sidelink signal may refer to a signal that is transmitted from one subordinate entity (e.g., UE 1) to another subordinate entity (e.g., UE2) 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, licensed spectrum may be used to convey sidelink signals (unlike wireless local area networks that typically use unlicensed spectrum).

[0145] 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 can 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 can be modified without departing from the scope of the claims.

[0148] 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 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 various aspects shown herein, but to conform to the full scope consistent with the language of the claims, wherein, unless otherwise specified, references to elements in the singular form are not intended to mean "one and only one", but to mean "one or more", and unless otherwise specified, the term "some" refers to one or more. All structural and functional equivalents of the elements of the various aspects described throughout the present disclosure that are known or will be known to a person of ordinary skill in the art are expressly incorporated herein by reference and are intended to be covered by the claims. In addition, nothing disclosed herein is intended to be dedicated to the public, regardless of whether such disclosure is explicitly recorded in the claims. Unless the claim element is explicitly recorded using the phrase "device for...", or in the case of a method claim, the element is recorded using the phrase "step for...", the claim element should not be interpreted according to the provisions of 35 U.S.C. §112 (f).

[0149] The various operations of the above methods may be performed by any suitable means capable of performing the corresponding functions. These units 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 shown in the accompanying drawings, those operations may have corresponding paired "means plus function" components with similar numbers.

[0150] The various illustrative logical blocks, modules, and circuits described in conjunction with the present disclosure may be implemented or performed 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 an 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.

[0151] 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 of the processing system and the overall design constraints, 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., keyboard, 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 with one or more general and / or special purpose processors. Examples include microprocessors, microcontrollers, DSP processors, and other circuits capable of executing software. Those skilled in the art will recognize how to best implement the described functionality of the processing system depending on the specific application and the overall design constraints imposed on the entire system.

[0152] If implemented in software, the function can be stored on or transmitted through 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 transmission of computer programs from one place to another. The processor can be responsible for managing the bus and general processing, including executing software modules stored on a machine-readable storage medium. The computer-readable storage medium can be coupled to the processor so that the processor can read information from the storage medium and write information to the storage medium. In an alternative, the storage medium can be integrated into the processor. As an example, the machine-readable medium can include a transmission line, a carrier modulated by data, and / or a computer-readable storage medium with instructions stored thereon separated from the wireless node, all of which can be accessed by the processor through a bus interface. Alternatively or additionally, the machine-readable medium or any part thereof can be integrated into the processor, such as the case can be a cache and / or a general register file. 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. The machine-readable medium may be embodied in a computer program product.

[0153] A software module may include a single instruction or many instructions, and may be distributed over several different code segments, between different programs, and over multiple storage media. A computer-readable medium may include multiple software modules. A software module includes instructions that cause a processing system to perform various functions when executed by a device such as a processor. A software module may include a sending module and a receiving module. Each software module may reside in a single storage device or may be distributed over 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 the processor. When referring to the functions of the following software modules, it will be understood that such functions are implemented by the processor when executing instructions from the software module.

[0154] 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 Disks, where magnetic disks typically reproduce data magnetically, and optical disks 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 transitory computer-readable media (e.g., signals). Combinations of the above should also be included within the scope of computer-readable media.

[0155] Thus, some 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, which may be executed by one or more processors to perform the operations described herein, for example, instructions for performing the operations described herein.

[0156] In addition, it should be appreciated that the modules and / or other appropriate means for performing the methods and techniques described herein can be downloaded and / or otherwise obtained by a user terminal and / or base station where applicable.
