Technical Field

[0004] In summary, the following text deals with wireless communications, and more specifically, with semi-persistent scheduling (SPS) management in new radio (NR). Background Technology

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (e.g., Long Term Evolution (LTE) systems or improved LTE (LTE-A) systems) and fifth-generation (5G) systems (which may be referred to as NR systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)) simultaneously.

[0006] The base station can configure the UE for SPS communication by scheduling the UE to send uplink messages at specific periods on reserved SPS resources. The UE can be configured to send feedback associated with downlink transmissions based on timing delays described by Hybrid Automatic Repeat Request (HARQ). In NR systems, HARQ timing can be dynamically indicated by each downlink transmission. More specifically, the downlink control information (DCI) that schedules downlink transmissions can be configured to indicate the HARQ timing associated with the downlink transmission. However, in the presence of downlink transmissions without scheduled DCIs, the UE may not receive HARQ timings. Summary of the Invention

[0007] The described technology relates to improved methods, systems, devices, or apparatuses for supporting semi-persistent scheduling (SPS) management in New Radio (NR). For example, the described technology provides a wireless communication network that can support SPS for uplink and downlink communications. In some cases, a base station can use SPS to schedule a User Equipment (UE) to send messages at specific periods on reserved SPS resources. In an NR system, the UE can be configured to send acknowledgment (ACK) / negative acknowledgment (NACK) in response to a downlink transmission, based on dynamic HARQ timing. For example, in an NR system, HARQ timing can be dynamically indicated to the UE in the scheduling downlink control information (DCI). In some examples, a 2-bit field in the DCI can be used to indicate HARQ timing. However, in an SPS-enabled NR system, there is no scheduling DCI for some SPS transmissions. In such cases, there is a need to efficiently determine the HARQ timing for transmissions without a scheduling DCI.

[0008] In one example, the UE can be configured to predetermine the HARQ timing for SPS transmissions without scheduled DCI. In some implementations, the UE can receive an indication of initiating a transmission based on an SPS configuration. For example, as part of the SPS configuration, the base station can indicate the period and resources used for the SPS transmission. Upon receiving the SPS configuration, the UE can be configured to assume the predetermined HARQ timing. In some examples, the predetermined HARQ timing value can depend on the UE's capabilities. For example, the UE's capability could be its ability to decode received downlink transmissions.

[0009] In another example, HARQ timing for SPS transmissions without a scheduled DCI can be configured via Radio Resource Control (RRC) signaling. In some implementations, the UE can receive an indication via RRC regarding initiating a transmission based on a received SPS configuration. In some examples, upon receiving RRC signaling, the UE can be configured to establish HARQ timing based on the RRC signaling and the capabilities associated with the UE. Alternatively, HARQ timing for SPS transmissions without a scheduled DCI can be configured by activating the most recent DCI of the SPS. For example, the UE can receive an indication from the base station to activate the DCI for the SPS configuration used for transmissions between the base station and the UE. In some cases, the UE can use the HARQ timing included in the DCI not only for downlink transmissions associated with the DCI but also for subsequent transmissions without a scheduled DCI.

[0010] In some wireless communication systems in NR, a UE can use component carriers (CCs) to establish a connection with a base station. A CC can include multiple bandwidth portions (BWPs), where each BWP has a portion of the frequency bandwidth of the CC. In some examples, the UE can receive an indication of activating a BWP. To efficiently manage the SPS configuration when the active BWP switches from one including SPS resources to one not including SPS resources, the UE and base station can use and / or activate a BWP-dependent SPS configuration. In some cases, the UE can be configured to receive signaling indicating the SPS configuration or other types of pre-configured resources associated with a first BWP. The UE can then use the first BWP to transmit or receive based on the received SPS configuration or other types of pre-configured resources. In some examples, when activating a BWP, the UE can receive a DCI that activates the SPS configuration associated with the active BWP.

[0055] Wireless communication networks can support semi-persistent scheduling (SPS) for uplink and downlink communication. Base stations can schedule and allocate resources for user equipment (UEs), allowing the UE to send and receive messages on the allocated resources. In some examples, the scheduled and allocated resources can be indicated to the UE in a scheduling grant carried in a subframe transmitted from the base station. In some examples, the scheduling grant can be sent periodically, for example, within each subframe in a set of subframes, as part of control information carried via the physical downlink control channel (PDCCH). By providing scheduling grants within each subframe, base stations (including the network) can have greater flexibility in assigning resources to the UE at the cost of sending resource allocation information on the PDCCH in each subframe. However, for services such as Voice over IP (VoIP), packet sizes are typically small, and packet arrival times are constant. To reduce the overhead of such operations, instead of periodically allocating resources, base stations can use SPS to allocate resources to the UE once. The UE can then be configured to use these resources at a set period.

[0056] In fourth-generation (4G) systems such as Long Term Evolution (LTE), SPS can be activated or deactivated via Downlink Control Information (DCI). In some implementations, the base station can transmit the DCI on the Physical Downlink Shared Channel (PDCCH). The PDCCH can be included in the Physical Downlink Shared Channel (PDSCH). In some cases, the PDCCH can be mapped to multiple Orthogonal Frequency Division Multiplexing (OFDM) symbols in a downlink subframe. In some cases, the PDCCH can be mapped to a predetermined number of OFDM symbols in each downlink subframe. For example, the predetermined number of OFDM symbols used for the PDCCH can be 1, 2, or 3. In some cases, the base station (such as an evolved Node B (eNB)) can use the Physical Control Format Indicator Channel (PCFICH) to inform the UE of the predetermined number of OFDM symbols. In some implementations, the DCI can be configured to include transport format, resource allocation, and information related to Hybrid Automatic Repeat Request (HARQ). In some examples, the DCI transmitted on the PDCCH can be protected by Cyclic Redundancy Check (CRC). In the SPS example, CRC scrambling can be achieved using the SPS Cell Radio Network Temporary Identifier (SPSC-RNTI).

[0057] In some implementations supporting SPS, the UE can receive the PDCCH and activate SPS for transmission between the base station and the UE based on the scheduling DCI included in the PDCCH. In some cases, after the first SPS transmission, the timing of subsequent SPS transmissions can depend on the transmission period and can be performed without a scheduling DCI. More specifically, after activation, subsequent SPS transmissions in a subframe can be based on the configured SPS period and can be scheduled without a scheduling DCI. In LTE, the UE can be configured to send feedback information to the base station using ACK / NACK. ACK / NACK can be sent according to HARQ timing. In some cases, HARQ timing can indicate the timing delay between the PDSCH and the corresponding HARQ response. In some cases, HARQ timing can be predetermined. For example, in Frequency Division Duplex (FDD), HARQ timing can follow a 4ms delay, and in Time Division Duplex (TDD), HARQ timing can follow a delay greater than 4ms. In some examples, HARQ timing in TDD can be configured based on TDD downlink (DL) / uplink (UL) subframes.

[0058] In fifth-generation (5G) or new radio (NR) systems, the UE can be configured to send ACK / NACK based on dynamic HARQ timing. For example, in NR systems, the delay between PDSCH and HARQ response can be based on a parameter (e.g., k1). In some implementations of NR systems, HARQ timing can be dynamically indicated to the UE in the scheduling DCI. For example, a 2-bit field in the DCI can be used to indicate HARQ timing. In some cases, the 2-bit field in the DCI can be configured to indicate four different values. For example, the DCI can indicate that a HARQ response can be sent in the same time slot, in a subsequent time slot, in the next available UL time slot, or a combination thereof. In some examples, HARQ timing can be dynamically configured by the base station (Gigabit Node B (gNB)). In some cases, the gNB can select HARQ timing based on the UE's operating conditions and the capabilities associated with the UE. For example, if the UE has high-performance capabilities, the gNB can configure the UE for reduced HARQ timing. As previously discussed, gNBs can use DCI to dynamically indicate HARQ timing. However, in NR systems that support SPS, there is a need to efficiently determine HARQ timing for transmissions without scheduled DCI.

[0059] To address the challenge of efficiently determining dynamic HARQ timing in NR systems, in some cases, the HARQ timing for SPS transmissions without a scheduled DCI can be predetermined. In some implementations, the UE can receive an indication of initiating a transmission based on the received SPS configuration. Upon receiving the SPS configuration, the UE can be configured to assume the predetermined HARQ timing. For example, the UE can be configured to assume a single delay value for sending ACK / NACK in response to a downlink transmission. In such a case, the UE can receive the initial HARQ timing in the initial DCI (or the DCI associated with the SPS configuration). The UE can use the HARQ timing indication in the initial DCI to send the ACK / NACK associated with the initial DCI. For example, the UE can send feedback to the base station indicating whether the initial DCI was successfully decoded after the timing delay indicated by the HARQ timing in the DCI. In some cases, for subsequent SPS transmissions without a scheduled DCI, the UE can be configured to use a predetermined HARQ timing value. In some examples, the predetermined HARQ timing value may depend on the UE's capabilities. For example, a UE's capability could be its ability to decode received downlink transmissions (received via PDSCH). In some implementations, the UE can be configured to indicate a predetermined HARQ timing to the base station, and the base station can adopt the received HARQ timing. As an example, the UE can assume a HARQ timing value of 4 (e.g., k1 = 4). In this example, the UE can send feedback (such as ACK / NACK) associated with the PDSCH in a time slot, which is sent four time slots after receiving the PDSCH.

[0060] In another example, HARQ timing for SPS transmissions without a scheduled DCI can be configured via Radio Resource Control (RRC) signaling. In some implementations, the UE can receive an indication of initiating a transmission via RRC based on the received SPS configuration. In some implementations, the UE can receive HARQ timing in RRC signaling. In some examples, upon receiving RRC signaling, the UE can be configured to establish HARQ timing based on the RRC signaling and the capabilities associated with the UE. In some cases, the UE capabilities may be static. In some cases, the UE can be configured to semi-statically determine the HARQ response timing delay (or HARQ timing). In some cases, the UE can maintain a capability profile. For example, the capability profile may indicate the minimum number of HARQ timing values ​​(such as the k1 value) supported by the UE. In some examples, the gNB can determine HARQ timing based on the UE's capability profile. In some examples, the UE's capability profile can be semi-statically configured when the UE does not use dynamic signaling options. In some cases, 2 bits in the DCI can be used to indicate dynamic signaling options. Alternatively, the UE can be configured to determine its capability profile based on the initial signaling procedure with the base station. In some cases, if two or more SPS instances exist, the SPS configuration and HARQ timing may be separate for each SPS instance.

[0061] Alternatively or concurrently, HARQ timing for SPS transmissions without a scheduled DCI can be configured by activating the most recent DCI of the SPS. For example, the UE can receive from the base station a DCI indicating the activation of the SPS configuration for transmissions between the base station and the UE. In some cases, the UE can receive the initial HARQ timing in the DCI. The UE can be configured to use the received HARQ timing for subsequent transmissions without a scheduled DCI. In some examples, the base station (such as a gNB) can be configured to send another activating DCI to update the HARQ timing value. In some examples, the activating DCI can indicate HARQ timing not only for the PDSCH transmission associated with activation but also for all subsequent PDSCH transmissions without a scheduled DCI. In some implementations, the HARQ timing for PDSCH transmissions without a scheduled DCI can additionally or concurrently depend on one or more other parameters. For example, the HARQ timing can depend on at least one of the following: slot structure, bandwidth portion (BWP) handover procedure, or a combination thereof. In some examples, the slot structure may include UL transmission opportunities for sending ACK / NACK in response to the DL transmission slot structure. In some cases, the slot structure can be dynamically indicated by at least one Slot Format Indicator (SFI). For example, if the slot structure indicates that the specified slot is designated for DL ​​transmission, the HARQ response can be skipped or postponed to the next opportunity.

[0062] In some wireless communication systems in NR, a UE can use component carriers (CCs) to establish a connection with a base station. A CC can include multiple component carriers (BWPs), each with a portion of the CC's frequency bandwidth. In some examples, a UE can be configured with two or more BWPs. In some implementations, BWPs can be a way to limit the UE's operating bandwidth at a given time. Saving bandwidth can be beneficial for low-bandwidth operation. For example, the CC could be 100 MHz, and the UE could operate within 20 MHz. In such examples, to save bandwidth and power, the UE can be configured to operate on a BWP on the CC. In some examples, a first BWP can be configured to include a first frequency range, and a second BWP can be configured to include a second frequency range. In some cases, the first and second frequency ranges do not overlap or partially overlap. In some cases, the UE can be dynamically switched from one BWP to another. This switching from one BWP to another can be performed using DCI. In current NR systems, one BWP is active at a time for the UE's serving base station. In NR systems with configured SPS, when two or more BWPs are configured to serve a cell (base station or gNB), and when the UE dynamically switches between BWPs, there is no efficient method to manage the SPS configuration during BWP switching.

[0063] To efficiently manage SPS configuration when switching an active BWP from one that includes SPS resources to one that does not, the UE and base station can use SPS configuration and / or activation that depend on the BWP. In one example, the SPS period and offset can be configured individually for each BWP. In some cases, the UE can be configured to receive signaling indicating the SPS configuration or other types of pre-configured resources associated with the first BWP. The UE can then use the first BWP to transmit or receive based on the received SPS configuration or other types of pre-configured resources.

[0064] To avoid disruptions to SPS availability, the base station can configure a set of BWPs or other resources that can support SPS configuration. In some cases, the base station can configure all BWPs to support SPS configuration. In other cases, resources for SPS configuration can be pre-configured on BWPs. This is because when the UE switches from a first BWP to a second BWP, the UE can still be configured to use the SPS resources associated with the second BWP without interruption. In some examples, SPS resources can be included in one BWP but not in another. In such cases, if the active BWP is not pre-configured to support SPS, the UE can assume that SPS is implicitly released.

[0065] In some examples, for an active BWP, the UE can be configured to determine the corresponding SPS slot based on the appropriate SPS configuration. In some examples, when activating a BWP, the UE can receive a DCI for activating the SPS. The UE can use the information from the DCI to activate PDSCH resources for one or more additional BWPs.

In some examples, the wireless communication system 100 may be an LTE network, an improved LTE (LTE-A) network, or an NR network. In some cases, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices.

[0068] Base station 105 can wirelessly communicate with UE 115 via one or more base station antennas. Base station 105 described herein may include, or may be referred to by those skilled in the art as, a base transceiver, wireless base station, access point, wireless transceiver, Node B, eNB, next-generation Node B, or gigabit Node B (any of which may be referred to as gNB), home Node B, home evolution Node B, or some other suitable term. Wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). UE 115 described herein is capable of communicating with various types of base stations 105 and network devices (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0069] Each base station 105 may be associated with a specific geographic coverage area 110 in which communication with each UE 115 is supported. Each base station 105 may provide communication coverage to the corresponding geographic coverage area 110 via a communication link 125, and the communication link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communication link 125 shown in the wireless communication system 100 may include: an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. The downlink transmission may also be referred to as a forward link transmission, and the uplink transmission may also be referred to as a reverse link transmission.

[0070] The geographic coverage area 110 for base station 105 can be divided into sectors, each sector constituting only a portion of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for macro cells, small cells, hotspots, or other types of cells, or various combinations thereof. In some examples, base station 105 can be mobile, and therefore, communication coverage is provided for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, and overlapping geographic coverage areas 110 associated with different technologies can be supported by the same base station 105 or different base stations 105. The wireless communication system 100 can include, for example, heterogeneous LTE / LTE-A or NR networks, where different types of base stations 105 provide coverage for individual geographic coverage areas 110.

[0071] The term "cell" refers to a logical communication entity used for communication with base station 105 (e.g., on a carrier) and may be associated with an identifier (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID)) used to distinguish neighboring cells operating via the same or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., Machine-Type Communication (MTC), Narrowband Internet of Things (NB-IoT), Enhanced Mobile Broadband (eMBB), or other protocol types) that can provide access for different types of devices. In some cases, the term "cell" may refer to a portion (e.g., a sector) of the geographical coverage area 110 on which the logical entity operates.

[0072] UE 115 may be distributed throughout the wireless communication system 100, and each UE 115 may be stationary or mobile. UE 115 may also be referred to as a mobile device, wireless device, remote device, handheld device, or user equipment, or some other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client. UE 115 may also be a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may also refer to a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or MTC device, which may be implemented in various items such as appliances, vehicles, instruments, etc.

[0073] In some cases, UE 115 can receive signaling from base station 105 to activate the SPS configuration for transmission between UE 115 and base station 105. UE 115 can then receive HARQ timing for downlink transmission based on the activation of SPS. In some cases, UE 115 can be configured to determine the HARQ timing value based on capabilities associated with UE 115. In some cases, the HARQ timing value can be predetermined.

[0074] In some examples, UE 115 can use a CC to establish a connection with base station 105. In some cases, the CC may have multiple BWPs, each BWP having a portion of the CC's frequency bandwidth. UE 115 can receive signaling indicating an SPS configuration or other type of pre-configured resources associated with at least a first BWP among the multiple BWPs. Upon receiving an SPS configuration, the UE can use at least the first BWP to transmit or receive based on the SPS configuration or other type of pre-configured resources associated with at least the first BWP.

[0075] In some examples, base station 105 may use CC to establish a connection with UE 115. Base station 105 may send signaling indicating SPS configuration or other types of pre-configured resources associated with at least a first BWP. Base station 105 may then use at least a first BWP to receive or transmit based on the SPS configuration or other types of pre-configured resources associated with at least a first BWP.

[0076] Some UE 115 devices (such as MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay that information to a central server or application that can utilize that information or present it to humans interacting with that program or application. Some UE 115 devices can be designed to collect information or enable automated machine behavior. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0077] Some UEs 115 can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving "deep sleep" mode when not engaged in active communication or operating on limited bandwidth (e.g., according to narrowband communication). In some cases, UE 115 may be designed to support critical functions (e.g., mission-critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communication for these functions.

[0078] In some cases, UE 115 can also communicate directly with other UE 115 (e.g., using peer-to-peer (P2P) or device-to-device (D2D) protocols). One or more UE 115s in a group utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105, or otherwise unable to receive transmissions from base station 105. In some cases, multiple groups of UE 115 communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some cases, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0079] Base station 105 can communicate with core network 130 and with each other. For example, base station 105 can interface with core network 130 via backhaul link 132 (e.g., via S1 or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130) on backhaul link 134 (e.g., via X2 or other interfaces).

[0080] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 may be an evolved packet core (EPC), which may include at least one Mobility Management Entity (MME), at least one Serving Gateway (S-GW), and at least one Packet Data Network (PDN) Gateway (P-GW). The MME can manage non-access stratum (e.g., control plane) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with the EPC. User IP packets can be transmitted via the S-GW, which itself may be coupled to the P-GW. The P-GW can provide IP address allocation and other functions. The P-GW may be coupled to network operator IP services. Operator IP services may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched (PS) streaming services.

[0081] At least some of the network devices (e.g., base station 105) may include sub-components such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with UE 115 through multiple other access network transport entities (which may be referred to as radio headends, smart radio headends, or transmit / receive points (TRPs)). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio headends and access network controllers) or incorporated into a single network device (e.g., base station 105).

[0082] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features. However, the waves can be sufficiently permeable to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum in the High Frequency (HF) or Very High Frequency (VHF) regions, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0083] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also known as the centimeter band). The SHF region includes frequency bands such as the 5 GHz industrial, scientific, and medical (ISM) band, which can be used opportunistically by devices capable of tolerating interference from other users.

[0084] The wireless communication system 100 can also operate in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be even smaller and more closely spaced compared to UHF antennas. In some cases, this can facilitate the use of antenna arrays within the UE 115. However, compared to SHF or UHF transmissions, EHF transmissions may suffer even greater atmospheric attenuation and shorter distances. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions can vary depending on the country or regulatory authority.

[0085] In some cases, system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 may employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed spectrum band (e.g., a 5 GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (e.g., base station 105 and UE 115) may employ a Listen-Before-Speak (LBT) procedure before transmitting data to ensure that the frequency channel is idle. In some cases, operation in the unlicensed spectrum band may be based on a CA configuration combined with CC operation in a licensed spectrum band (e.g., LAA). Operation in the unlicensed spectrum may include downlink transmission, uplink transmission, peer-to-peer transmission, or a combination of these. Duplexing in the unlicensed spectrum may be based on Frequency Division Duplex (FDD), Time Division Duplex (TDD), or a combination of both.

[0086] In some examples, base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. For example, wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., base station 105) and a receiving device (e.g., UE 115), wherein the transmitting device is equipped with multiple antennas, and the receiving device is equipped with one or more antennas. MIMO communication may employ multipath signal propagation to improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers (this may be referred to as spatial multiplexing). For example, the transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, the receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (where multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are sent to multiple devices).

[0087] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105 or UE 115) to form or guide an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that signals propagating relative to a specific orientation of the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude and phase offsets to the signals carried by the transmitting or receiving device via each of the antenna elements associated with that device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0088] In one example, base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with UE 115. For example, base station 105 may transmit signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions, these signals may include signals transmitted according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used (e.g., by base station 105 or receiving device (e.g., UE 115)) to identify the beam direction for subsequent transmissions and / or receptions performed by base station 105. Base station 105 may transmit signals (e.g., data signals associated with a specific receiving device) in a single beam direction (e.g., the direction associated with the receiving device (e.g., UE 115)). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report to base station 105 an indication of the signal it received that has the highest signal quality or otherwise acceptable signal quality. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0089] When receiving various signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., UE 115, which may be an example of an mmW receiving device) can attempt multiple receive beams. For example, the receiving device can attempt multiple receive directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of the antenna array, or by processing the received signals according to different sets of receive beamforming weights applied to the signals received at multiple antenna elements of the antenna array (any of the above operations can be referred to as “listening” according to different receive beams or receive directions). In some examples, the receiving device can use a single receive beam to receive along a single beam direction (e.g., when receiving data signals). A single receiving beam can be aligned on a beam direction determined based on listening to different receiving beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or otherwise acceptable signal quality based on listening to multiple beam directions).

[0090] In some cases, the antennas of base station 105 or UE 115 may be located within one or more antenna arrays that can support MIMO operation or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have antenna arrays with multiple rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations.

[0091] In some cases, the wireless communication system 100 may be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer may be IP-based. In some cases, the Radio Link Control (RLC) layer may perform packet segmentation and reassembly for communication on logical channels. The Media Access Control (MAC) layer may perform priority handling and multiplexing of logical channels to transport channels. The MAC layer may also use HARQ to provide retransmissions at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer may provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between UE115 and base station 105 or core network 130. At the physical (PHY) layer, transport channels may be mapped to physical channels.

[0092] In some cases, UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. HARQ feedback is a technique to increase the likelihood of correct data reception on communication link 125. HARQ may include a combination of error detection (e.g., using CRC), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., signal and noise conditions). In some cases, the radio device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0093] Time intervals in LTE or NR can be represented as multiples of a basic time unit (which can, for example, refer to a sampling period of Ts = 1 / 30,720,000 seconds). Time intervals for communication resources can be organized according to radio frames, each with a duration of 10 milliseconds (ms), where the frame period can be expressed as Tf = 307,200Ts. Radio frames can be identified by System Frame Numbers (SFNs) ranging from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and each subframe can have a duration of 1 ms. Subframes can be further divided into two time slots, each with a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix added before each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the smallest scheduling unit of a wireless communication system 100 and can be referred to as a Transmission Time Interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0094] In some wireless communication systems, time slots can be further divided into multiple micro-time slots containing one or more symbols. In some instances, the symbol or micro-time slot of a micro-time slot can be the smallest scheduling unit. The duration of each symbol can vary depending on, for example, the subcarrier spacing or the frequency band of operation. Furthermore, some wireless communication systems can implement time slot aggregation, where multiple time slots or micro-time slots are aggregated together and used for communication between UE 115 and base station 105.

[0095] The term "carrier" refers to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication on communication link 125. For example, a carrier of communication link 125 may include a portion of the radio frequency spectrum band that operates according to physical layer channels for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. Carriers may be associated with predefined frequency channels (e.g., E-UTRA Absolute Radio Channel Number (EARFCN)) and may be positioned according to a channel grid for discovery by UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or may be configured to carry both downlink and uplink communication (e.g., in TDD mode). In some examples, the signal waveform transmitted on a carrier may consist of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as OFDM or DFT-s-OFDM).

[0096] The organization of carriers can vary depending on the radio access technology (e.g., LTE, LTE-A, NR, etc.). For example, communication on a carrier can be organized according to a Time Interval (TTI) or time slot, each of which can include user data and control information or signaling to support the decoding of the user data. A carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information) and control signaling to coordinate operations on the carrier. In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate operations on other carriers.

[0097] Physical channels can be multiplexed on a carrier using various techniques. For example, time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. In some examples, control information transmitted in the physical control channel can be distributed in a concatenated manner between different control regions (e.g., between a common control region or common search space and one or more UE-specific control regions or UE-specific search spaces).

[0098] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of several predetermined bandwidths for a carrier specific to a wireless access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 can be configured to operate on a portion or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range within the carrier (e.g., a set of subcarriers or RBs) (e.g., “in-band” deployment of a narrowband protocol type).

[0099] In systems employing MCM technology, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. In MIMO systems, wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers), and the use of multiple spatial layers can further increase the data rate used for communication with UE 115.

[0100] The devices of the wireless communication system 100 (e.g., base station 105 or UE 115) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configurable to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base station 105 and / or UE, which are capable of supporting simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0101] The wireless communication system 100 can support communication with the UE 115 on multiple cells or carriers (a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation). Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink CCs and one or more uplink CCs. Carrier aggregation can be used in conjunction with both FDD and TDD component carriers.

[0102] In some cases, the wireless communication system 100 may utilize enhanced component carriers (eCC). eCC can be characterized by one or more features including: a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, eCC may be associated with carrier aggregation or dual connectivity configurations (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). eCC can also be configured for use in unlicensed or shared spectrum (e.g., where more than one operator is permitted to use the spectrum). eCC characterized by a wide carrier bandwidth may include one or more segments that can be used by a UE 115 that cannot monitor the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., to save power).

[0103] In some cases, eCC can utilize a different symbol duration than other CCs, which may include using a reduced symbol duration compared to other CCs. A shorter symbol duration can be associated with increased spacing between adjacent subcarriers. Devices utilizing eCC (e.g., UE 115 or base station 105) can transmit wideband signals (e.g., based on frequency channels or carrier bandwidths of 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). The TTI in eCC can include one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in the TTI) can be variable.

[0104] In addition, wireless communication systems (such as NR systems) can utilize any combination of licensed, shared, and unlicensed spectrum bands. The flexibility in eCC symbol duration and subcarrier spacing allows for the use of eCC across multiple spectrums. In some examples, NR spectrum sharing can improve spectrum utilization and efficiency, especially through dynamic vertical (e.g., across frequency) and horizontal (e.g., across time) sharing of resources.

[0105] Figure 2 Examples of wireless communication systems 200 supporting SPS management in NR according to various aspects of this disclosure are shown. In some examples, wireless communication system 200 may implement aspects of wireless communication system 100.

[0106] exist Figure 2 In the example, the wireless device (e.g., UE 115-a) may support communication on carrier 205. The wireless communication system 200 may be a 5G or NR system supporting SPS for uplink and downlink communication. Base station 105-a may schedule UE 115-a to transmit uplink messages on reserved resources. According to the various techniques described previously, UE 115-a may receive resource allocation information on the PDCCH. More specifically, UE 115-a may receive a PDCCH including a PDSCH. In some implementations, UE 115-a may receive an indication to activate the SPS configuration. In some cases, the indication to activate SPS may be received via DCI. In some cases, base station 105-a may transmit the DCI on carrier 205. Upon receiving a signal to activate the SPS configuration, UE 115-a may activate the SPS configuration for transmission between base station 105-a and UE 115-a. In some examples, the SPS configuration may be activated based on the scheduling DCI included in the PDCCH. In some implementations, UE 115-a can be configured to determine the HARQ timing upon receiving the SPS configuration (via DCI in the PDCCH). In some cases, the HARQ timing can be predetermined. In some implementations, UE 115-a can be configured to assume a delay value (or HARQ timing) for sending ACK / NACK in response to downlink transmissions.

[0107] In some implementations, UE 115-a can receive an initial DCI indicating activation of the SPS configuration from base station 105-a. As previously discussed, the initial DCI may be part of the PDCCH. In some cases, the initial DCI may include an initial HARQ timing. UE 115-a can therefore receive the DCI and recognize the HARQ timing indicated by the DCI. In some cases, UE 115-a can use a determined HARQ timing to send an ACK / NACK associated with the initial DCI. As an example, UE 115-a can send feedback (in the form of ACK or NACK) to base station 105-a indicating whether the initial DCI was successfully decoded. This feedback can be sent after a timing delay indicated by the HARQ timing in the initial DCI.

[0108] In some cases, after activating the SPS configuration, UE 115-a can be configured to send uplink messages to base station 105-a according to the period set by the SPS configuration. In such cases, UE 115-a may not receive the scheduling DCI for each subsequent transmission. In some examples, for subsequent transmissions without a scheduling DCI, UE 115-a can use a predetermined HARQ timing value. In some examples, the predetermined HARQ timing value may depend on the UE capabilities. As previously discussed, UE capabilities can be based on a capability profile.

[0109] According to the second example, HARQ timing values ​​for sending feedback associated with SPS transmissions can be configured via RRC signaling. For example, UE 115-a can receive RRC signals from base station 105-a. The RRC signals can indicate whether to initiate a transmission based on the received SPS configuration. In some implementations, UE 115-a can receive HARQ timing in the RRC signaling. Upon receiving the HARQ timing value, UE 115-a can provide feedback to base station 105-a using the timing delay indicated by the HARQ timing value. In some examples, upon receiving RRC signaling, UE 115-a can be configured to establish HARQ timing based on the RRC signaling and the capabilities associated with UE 115-a. In some cases, the capabilities can be based on the minimum value of the HARQ timing supported by UE 115-a. In some cases, the capabilities of UE 115-a can be static.

[0110] In another example, HARQ timing for SPS transmissions without a scheduled DCI can be configured by activating the most recent DCI of the SPS. For example, as previously discussed, UE 115-a can receive a DCI from base station 105-a indicating the activation of the SPS configuration for transmissions between the base station and the UE. In some examples, UE 115-a can receive the initial HARQ timing in the DCI that activates the SPS configuration. UE 115-a can then be configured to use the received HARQ timing for subsequent transmissions without a scheduled DCI. In some examples, UE 115-a can continue using the HARQ timing value until base station 105-a updates the HARQ timing value. For example, base station 105-a can update the HARQ timing value via a second activated DCI.

[0111] Figure 3 Examples of wireless communication systems 300 supporting SPS management in NR according to various aspects of this disclosure are shown. In some examples, wireless communication system 300 may implement aspects of wireless communication system 100 and wireless communication system 200, as referenced Figure 1 and Figure 2 As described.

[0112] exist Figure 3 In the example, base station 105-b and UE 115-b can establish a connection (not shown). In some cases, the connection can have one or more wideband CCs. As noted above, in some cases, one or more CCs can include one or more BWPs. For example, a CC can include two or more BWPs. In some cases, base station 105-a can configure connection 305 to have two or more BWPs, and one or more BWPs can be activated and deactivated via DCI signaling. In some cases, UE 115-b can receive a signal regarding the activation of a first BWP, and the second BWP can be inactive by default. In some implementations, base station 105-b can activate the second BWP by sending a DCI to UE 115-a indicating that the second BWP will be activated. UE 115-b can receive the DCI, and in some cases, acknowledge the reception of the DCI. In some cases, UE 115-b can acknowledge the reception of the DCI after a timing delay indicated by HARQ timing.

[0113] As described above, in some cases, base station 105-b can activate one or more BWPs via a scheduling DCI sent to UE 115-b. In such cases, multiple BWPs can be configured, and the DCI can include indications of which BWPs are active for a specific transmission or within a predetermined time period. Upon receiving the DCI, UE 115-b can activate the BWPs indicated as active and deactivate any previously active BWPs that are no longer indicated as active. In some examples, base station 105-b can send the BWP DCI to UE 115-b on the active beam via beamforming transmission 320.

[0114] In some examples, UE 115 can receive indications of SPS resources associated with an active BWP. For example, base station 105-b can be configured to determine an SPS configuration and several BWPs associated with the SPS configuration. For example, base station 105-b can configure a set of BWPs or other resources in which the SPS configuration can be supported. In some examples, base station 105-b can configure all BWPs to support the SPS configuration. In some examples, base station 105-b can configure a subset of BWPs to support the SPS configuration. In some cases, base station 105-b can pre-configure resources for the SPS configuration on BWPs. In some examples, SPS resources can be included in one BWP but not in another. In such cases, if the active BWP is not pre-configured to support SPS, UE 115-b can consider the SPS to be implicitly released.

[0115] In some examples, base station 105-b can send an indication to UE 115-b regarding the handover of the BWP. In some cases, if the active BWP is switched from a first BWP to a second BWP, UE 115-b can use the SPS configuration associated with the second BWP for transmitting or receiving. For example, base station 105-b can indicate information associated with the SPS configuration in the signal indicating the handover of the BWP. In one example, the SPS period and offset can be configured individually for each BWP.

[0116] Figure 4 An example of a process flow 400 supporting SPS management in NR according to various aspects of this disclosure is shown. In some examples, process flow 400 can implement various aspects of wireless communication system 100. Base station 105-c can be as described in reference Figure 1 An example of the described base station 105. UE 115-c can be as shown in the reference. Figure 1 An example of UE 115 as described.

[0117] In the following description of process flow 400, operations between base station 105-c and UE 115-c may be transmitted in a different order than the exemplary order shown, or operations performed by base station 105-c and UE 115-c may be performed in a different order or at different times. Some operations may be omitted in process flow 400, or other operations may be added to process flow 400.

[0118] At 405, base station 105-c can transmit a signal to activate the SPS configuration for transmission between base station 105-c and UE 115-c, as shown in reference. Figure 1 and Figure 2 As described. In some examples, the signal may be a PDCCH signal that includes a DCI indicating information associated with the SPS configuration. In some cases, the DCI may indicate the initiation of an SPS configuration, the period of an upcoming SPS transmission, etc.

[0119] At 410, UE 115-c can determine the DCI included in the signal. In some examples, UE 115-c can receive the initial HARQ timing as part of the signaling. In some cases, the HARQ timing can be used to send feedback associated with the DCI. In some cases, the HARQ timing can be used by UE 115-c to send feedback in response to subsequent downlink transmissions without scheduled DCI. At 415, upon receiving the SPS configuration signal and determining the DCI, UE 115-c can activate the SPS configuration for transmissions between base station 105-c and UE 115-c.

[0120] At 420, UE 115-c can receive downlink transmissions from base station 105-c. At 425, UE 115-c can determine HARQ timing to provide feedback associated with the downlink transmissions. In one example, the HARQ timing value can be predetermined. For example, UE 115-c can predetermine the HARQ timing value based on UE capabilities. In another example, the HARQ timing value can be indicated by RRC signaling (not shown). In yet another example, the HARQ timing value can be the value indicated in the DCI received by UE 115-c at 405. In such a case, UE 115-c can continue to use the HARQ timing value associated with the DCI until the DCI is updated.

[0121] At 425, UE 115-c can send ACK / NACK in response to downlink transmission based on the timing delay indicated by the received HARQ timing.

Some operations may be omitted in process flow 500, or other operations may be added to process flow 500.

[0124] At 505, base station 105-d can identify multiple BWPs. In some examples, each BWP may include a portion of the frequency bandwidth of a primary CC. In some cases, a first BWP may include a first frequency range, and a second BWP may include a second frequency range, wherein the first and second frequency ranges do not overlap. At 510, base station 105-d can identify a subset of BWPs from the multiple BWPs and associate the subset of BWPs with an SPS configuration. At 515, base station 105-d and UE 115-d can establish a connection with each other using a CC. In some cases, the CC has multiple BWPs. In some cases, UE 115-d can receive signaling indicating the SPS configuration or other types of pre-configured resources associated with the BWP. In some examples, the signaling may include DCI and RRC messages.

[0125] At point 525, during connection establishment, UE 115-d can activate the BWP and determine the SPS configuration associated with the activated BWP. In some cases, UE 115-d can determine other types of pre-configured resources associated with the activated BWP. At point 530, UE 115-d and base station 105-d can use the activated BWP for transmission or reception based on the SPS configuration associated with the activated BWP or other types of pre-configured resources.

[0126] At 535, UE 115-d can switch from the first BWP to the second BWP. In some cases, the handover may be in response to signaling indicating the SPS configuration or other types of pre-configured resources associated with the second BWP (not shown). At 540, UE 115-d can determine the SPS configuration information associated with the second BWP. In some cases, UE 115-d can determine other types of pre-configured resources associated with the second BWP. At 545, UE 115-d can use the second BWP to transmit or receive based on the determined SPS configuration or other types of pre-configured resources associated with the second BWP.

CDMA systems can implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). CDMA2000 encompasses the IS-2000, IS-95, and IS-856 standards. Versions of IS-2000 are often referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is often referred to as CDMA2000 1xEV-DO, High-Speed ​​Packet Data (HRPD), etc. UTRA includes Wideband CDMA (W-CDMA) and other variations of CDMA. TDMA systems can implement radio technologies such as Global System for Mobile Communications (GSM).

[0210] Macro cells typically cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UE 115 with a service subscription to a network provider. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed, etc.) frequency bands as macro cells. Depending on the examples, small cells can include picocells, femtocells, and microcells. For example, a picocell can cover a small geographic area and allow unrestricted access by UE 115 with a service subscription to a network provider. A femtocell can also cover a small geographic area (e.g., a residential area) and provide restricted access by UE 115 associated with that femtocell (e.g., UE 115 in a Closed Subscriber Group (CSG), UE 115 for a user in a residence, etc.). An eNB for a macro cell can be referred to as a macro eNB. An eNB for a small cell can be referred to as a small cell eNB, pico eNB, femtocell eNB, or home eNB. eNB can support one or more (e.g., two, three, four, etc.) cells, and can also support communication using one or more component carriers.

[0211] The wireless communication system 100 or more systems described herein can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timing, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timing, and transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0212] The information and signals described herein can be represented using any of a variety of different techniques and methods. For example, the data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the above description can be represented by voltage, current, electromagnetic waves, magnetic fields or particles, light fields or particles, or any combination thereof.

The general-purpose processor may be a microprocessor, but alternatively, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration).

[0214] The functions described herein can be implemented using hardware, software executed by a processor, firmware, or any combination thereof. If implemented using software executed by a processor, the functions can be stored as one or more instructions or code on or transmitted through a computer-readable medium. Other examples and implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described above can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including being distributed such that different parts of the functions are implemented in different physical locations.

[0215] Computer-readable media includes both non-transitory computer storage media and communication media, with communication media encompassing any medium that facilitates the transfer of computer programs from one place to another. Non-transitory storage media can be any available medium accessible by a general-purpose computer or a special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media can include RAM, ROM, electrically erasable programmable read-only memory (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage, disk storage or other magnetic storage devices, or any other non-transitory medium capable of carrying or storing desired units of program code in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer, or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of media. As used herein, disks and optical discs include CDs, laser discs, optical discs, digital multifunction discs (DVDs), floppy disks, and Blu-ray discs. Disks typically copy data magnetically, while optical discs use lasers to copy data optically. The combinations described above are also included within the scope of computer-readable media.

[0216] As used herein (including in the claims), the word "or" in a list of items (e.g., a list of items ending with a phrase such as "at least one of" or "one or more of") indicates an inclusive list, such that a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an exemplary step described as "based on condition A" may be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0217] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by a dash followed by a second reference numeral, used to differentiate between similar components. If only the first reference numeral is used in the specification, the description applies to any one of the similar components having the same first reference numeral, without regard to the second reference numeral or other subsequent reference numerals.

[0218] This document describes exemplary configurations with reference to the accompanying drawings, but does not represent all examples that can be implemented or that are within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." Detailed descriptions include specific details for the purpose of providing an understanding of the described techniques. However, these techniques may be implemented without these specific details. In some instances, well-known structures and devices are shown in block diagram form to avoid obscuring the concepts of the described examples.
