[0003] background

[0004] The following relates generally to wireless communications and, more particularly, to periodic receive modes for wireless communications.

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to 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 (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems), and fifth generation (5G) systems, which may be referred to as new radio (NR) systems. These systems may employ various 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 orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each of which simultaneously supports communication with multiple communication devices, which may be further referred to as user equipment (UE).

[0006] In some cases, the arrival rate of data for a UE at a base station may not depend on the throughput supported by the radio link between the base station and the UE (e.g., may not change in response to the throughput supported by the radio link between the base station and the UE), and thus the data for the UE may be referred to as inelastic (e.g., inelastic traffic or inelastic data). For example, a server or other component of the network may artificially limit (throttle) the data rate of the UE so that the rate at which data for the UE arrives at the base station may be static (e.g., capped) even if the throughput of the radio link to the UE (e.g., supported or possible throughput) increases. For example, this may occur when the UE is accessing a streaming service and the server or other components of the network are configured to minimize load and resource waste. As another non-limiting example, a bottleneck may exist somewhere in the network other than between the base station and the UE (e.g., in the core network of the wireless communication network or in the Internet), such that the rate at which data for the UE arrives at the base station may not change even if the throughput of the radio link to the UE increases or decreases within a range above the rate supported by the bottleneck.

[0007] Overview

[0008] The described technology relates to improved methods, systems, devices and apparatuses for supporting a periodic reception mode for wireless communications. Generally, the described technology provides improved power saving at a UE. Some wireless communication systems support UEs to achieve power saving by operating in a periodic reception mode. In the periodic reception mode, the UE can switch between an active state and an inactive state for data transmission and reception to save power. The base station can determine that the data arrival rate does not change with the throughput of the radio link associated with the UE. To account for such inelastic traffic, the base station can combine multiple packets and transmit the combined transmission as a data burst. The UE can identify activation of the periodic reception mode. For example, the UE can receive an activation signal from the base station. The activation signal can activate the periodic reception mode at the UE. In some cases, the activation signal can indicate a periodic scheduling including the duration and periodicity of the UE's active state (such as a data transmission and / or reception period) and the inactive state (such as a low power period). The UE can be configured with or otherwise identify the duration of the active state and the inactive state. In some cases, the UE can identify the duration based on the activation signal. The UE may determine whether data is available by monitoring a control channel such as a physical downlink control channel (PDCCH) according to an active state indicated in a periodic schedule associated with the periodic reception mode. Additionally, the UE may sleep according to an inactive state indicated in a periodic schedule associated with the periodic reception mode.

[0070] Detailed description

[0071] In some wireless communication systems (e.g., millimeter wave (mmW) systems), the data arrival rate at the base station may not depend on the throughput supported by the wireless link between the base station and the UE. For example, the data arrival rate of the UE may not change in response to changes in the throughput of the wireless link. As an example, the server of the streaming service or other components of the network may artificially limit (e.g., throttle) the data rate of the UE so that the rate at which the UE's data arrives at the base station may be static (e.g., capped) even if the throughput of the wireless link between the base station and the UE increases. Such data of the UE may be referred to as inelastic (e.g., inelastic traffic or inelastic data).

[0072] As described herein, to reduce power consumption associated with repeatedly monitoring scheduled on-durations at a UE, a base station may determine that the UE's data traffic is inelastic and activate a periodic reception mode at the UE. In some cases, the periodic reception mode may be based on the UE's latency tolerance (e.g., the latency tolerance of an application at the UE associated with inelastic data) and the throughput of a radio link associated with the UE. That is, the base station may determine that the data arrival rate does not vary with the throughput of the radio link associated with the UE. In such cases, if the UE's data traffic is delay-tolerant, the base station may combine multiple packets and transmit the combined transmission as a data burst. Thus, the base station may compress the UE's traffic into fewer data bursts and increase the time gaps between them, which may allow the UE to save power by sleeping during the increased time gaps while maintaining, or at least substantially maintaining, the overall (e.g., average) data rate at which the UE receives inelastic data traffic.

[0073] In the periodic reception mode, the base station may initiate the periodic reception mode by transmitting an activation signal. In some cases, the activation signal may indicate the duration and periodicity of an active state (such as a data transmission and / or reception period). Additionally or alternatively, the activation signal may indicate the duration and periodicity of an inactive state (such as a low-power time period) of the UE. In some cases, the UE may switch between an active state for data transmission and reception and an inactive state (such as a "sleep" state) to save power. The UE may be configured with or otherwise identify active durations (such as durations when the UE is in an active state) that include data or control information from the base station. In some cases, the UE may identify active durations based on activation signals received from the base station. Therefore, the UE may monitor these identified active durations for data. In some cases, the UE may avoid monitoring inactive durations to reduce power consumption.

[0074] Aspects of the present disclosure are initially described in the context of a wireless communication system. Aspects of the present disclosure are further illustrated and described by and with reference to diagrams and flow charts related to a periodic reception mode for wireless communication.

[0075] Figure 1 An example of a wireless communication system 100 supporting a periodic reception mode for wireless communication according to various aspects of the present disclosure is illustrated. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be an LTE network, an LTE-Advanced network, an LTE-Advanced Pro network, or a New Radio (NR) network. In some cases, the wireless communication system 100 can support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices.

[0076] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next-generation Node B, or a gigabit Node B (any of which may be referred to as a gNB), a Home Node B, a Home eNode B, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be capable of communicating with various types of base stations 105 and network equipment (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0077] Each base station 105 may be associated with a particular geographic coverage area 110 in which it supports communications with various UEs 115. Each base station 105 may provide communication coverage for the respective 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. Downlink transmissions may also be referred to as forward link transmissions, while uplink transmissions may also be referred to as reverse link transmissions.

[0078] The geographic coverage area 110 of a base station 105 can be divided into sectors that constitute 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 a macrocell, a small cell, a hotspot, or other types of cells, or various combinations thereof. In some examples, the base station 105 can be mobile and, therefore, provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, and the 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, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0079] The term "cell" refers to a logical communication entity used to communicate with base station 105 (e.g., on a carrier) and can be associated with an identifier to distinguish between adjacent cells operating via the same or different carriers (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)). In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types that can provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), or other). In some cases, the term "cell" can refer to a portion of the geographic coverage area 110 (e.g., a sector) on which the logical entity operates.

[0080] UEs 115 may be dispersed 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 subscriber device, or some other suitable term, where "device" may also be referred to as a unit, station, terminal, or client. UE 115 may also be a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which may be implemented in various items (such as appliances, vehicles, meters, etc.).

[0081] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that incorporate sensors or meters to measure or capture information and relay that information to a central server or application, which may utilize the information or present it to a person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wilderness survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0082] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UEs 115 include entering a power saving "deep sleep" mode when not engaged in active communications, or operating over a limited bandwidth (e.g., in accordance with narrowband communications). In some cases, UEs 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.

[0083] In some cases, a UE 115 may also be able to communicate directly with other UEs 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more UEs in a group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some cases, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between the UEs 115 without involving the base station 105.

[0084] The base stations 105 can communicate with the core network 130 and with each other. For example, the base stations 105 can interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130) on a backhaul link 134 (e.g., via X2, Xn, or other interfaces).

[0085] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The 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 may manage non-access stratum (e.g., control plane) functions such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the EPC. User IP packets may be delivered through the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to network operator IP services. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or packet switched (PS) streaming services.

[0086] At least some network devices (such as base stations 105) may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with various UEs 115 through a number of other access network transport entities, which may be referred to as radio heads, smart radio heads, 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 heads and access network controllers) or consolidated into a single network device (e.g., base station 105).

[0087] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelengths range from approximately 1 decimeter to 1 meter long. UHF waves can be blocked or redirected by buildings and environmental features. However, these waves can penetrate various structures sufficiently for macrocells to provide service to UEs 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and a shorter range (e.g., less than 100 km) compared to transmissions using the lower frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0088] The wireless communication system 100 may also operate in the Super High Frequency (SHF) region using frequency bands from 3 GHz to 30 GHz (also known as centimeter bands). The SHF region includes frequency bands that may be opportunistically used by devices that may be able to tolerate interference from other users, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band.

[0089] The wireless communication system 100 may also operate in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as the millimeter band. In some examples, the wireless communication system 100 may support mmW communications between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be even smaller and more closely spaced than the UHF antennas. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may differ by country or regulatory agency.

[0090] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed frequency band (such as the 5 GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (such as base stations 105 and UEs 115) may employ a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operations in the unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating in the licensed band. Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in the unlicensed spectrum may be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of the two.

[0091] In some examples, base station 105 or UE 115 may be equipped with multiple antennas, which may 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 employ a transmission scheme between a transmitting device (e.g., base station 105) and a receiving device (e.g., UE 115), where the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication may exploit multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, a receiving device may receive multiple signals via different antennas or different antenna combinations. Each of these 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 for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device, and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0092] 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 device or a receiving device (e.g., a base station 105 or a UE 115) to shape or steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals conveyed via antenna elements of an antenna array so that signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals conveyed via the antenna elements can include the transmitting device or the receiving device applying a specific amplitude and phase shift to the signal carried via each antenna element associated with the device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0093] In one example, the base station 105 can use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) can be transmitted multiple times by the base station 105 in different directions, which can include a signal being transmitted according to different sets of beamforming weights associated with different transmission directions. The transmissions in different beam directions can be used (e.g., by the base station 105 or a receiving device, such as the UE 115) to identify a beam direction for subsequent transmission and / or reception by the base station 105.

[0094] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction (e.g., a direction associated with a recipient device, such as UE 115). In some examples, the beam direction associated with transmissions along the 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 an indication of the received signal having the highest signal quality or other acceptable signal quality to base station 105. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a recipient device).

[0095] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may attempt multiple receive beams when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may attempt multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some examples, the receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). The single receive beam may be aligned on a beam direction determined based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or other acceptable signal quality based on listening according to multiple beam directions).

[0096] In some cases, the antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays that can support MIMO operations 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 a base station 105 may be located at different geographic locations. A base station 105 may have an antenna array with several rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Similarly, a UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations.

[0097] In some cases, the wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate on the logical channel. The MAC layer can perform priority handling and multiplex logical channels into transport channels. The MAC layer can also use HARQ to provide retransmission at the MAC layer, thereby improving link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer supporting user plane data between the UE 115 and the base station 105 or the core network 130. In the physical layer, the transport channel can be mapped to the physical channel.

[0098] In some cases, the UE 115 and the base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood of correctly receiving data on the communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve MAC layer throughput in poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a particular time slot for data received in previous symbols in that time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or based on some other time interval.

[0099] The time interval in LTE or NR can be represented by a basic time unit (which may be, for example, a sampling period T s =1 / 30,720,000 seconds). The time interval of the communication resources can be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period can be expressed as T f =307,200T s. A radio frame may be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1 ms. A subframe may be further divided into 2 slots, each slot having a duration of 0.5 ms, and each slot may contain 6 or 7 modulation symbol periods (e.g., depending on the length of a cyclic prefix prepended to each symbol period). Excluding the cyclic prefix, each symbol period may contain 2048 sampling periods. In some cases, a subframe may be the minimum scheduling unit of the wireless communication system 100 and may 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 a shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0100] In some wireless communication systems, a time slot can be further divided into multiple mini-slots containing one or more symbols. In some instances, a symbol of a mini-slot or a mini-slot can be the smallest scheduling unit. For example, the duration of each symbol can vary depending on the subcarrier spacing or the operating frequency band. Furthermore, some wireless communication systems can implement time slot aggregation, in which multiple time slots or mini-slots are aggregated and used for communication between UE 115 and base station 105.

[0101] The term "carrier" refers to a set of radio frequency spectrum resources that has a defined physical layer structure for supporting communications on the communication link 125. For example, a carrier of the communication link 125 may include a portion of a radio frequency spectrum band that operates according to a physical layer channel for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an Evolved Universal Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid for discovery by the UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or configured to carry downlink and uplink communications (e.g., in TDD mode). In some examples, a signal waveform transmitted on a carrier may include multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)).

[0102] The organizational structure of a carrier can be different for different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR). For example, communications on a carrier can be organized according to time intervals (TTIs) or time slots, each of which can include user data and control information or signaling to support decoding of the user data. A carrier can also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate carrier operations. In some examples (e.g., in a carrier aggregation configuration), a carrier can also have acquisition signaling or control signaling to coordinate the operations of other carriers.

[0103] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier using, for example, time division multiplexing (TDM), frequency division multiplexing (FDM), or a hybrid TDM-FDM technique. In some examples, control information transmitted in a physical control channel may be distributed in a concatenated manner across 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).

[0104] A carrier may be associated with a particular bandwidth of radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 may be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 may be configured to operate using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0105] In a system 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 may depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate of the UE 115 can be. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers), and the use of multiple spatial layers may further increase the data rate of communications with the UE 115.

[0106] A device of the wireless communication system 100 (e.g., a base station 105 or a UE 115) may have a hardware configuration that supports communication on a particular 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 a base station 105 and / or a UE 115 that supports simultaneous communication via carriers associated with more than one different carrier bandwidth.

[0107] The wireless communication system 100 may support communication with a UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation or multi-carrier operation. The UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both FDD and TDD component carriers.

[0108] In some cases, the wireless communication system 100 may utilize an enhanced component carrier (eCC). An eCC may be characterized by one or more characteristics 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, an eCC may be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC may also be configured for use in unlicensed spectrum or shared spectrum (e.g., where more than one operator is allowed to use the spectrum). An eCC characterized by a wide carrier bandwidth may include one or more segments that may be utilized by UEs 115 that are unable to monitor the entire carrier bandwidth or are otherwise configured to use a limited carrier bandwidth (e.g., to save power).

[0109] In some cases, an eCC may utilize a different symbol duration than other component carriers, which may include using a reduced symbol duration compared to the symbol duration of other component carriers. The shorter symbol duration may be associated with increased spacing between adjacent subcarriers. A device utilizing an eCC (such as a UE 115 or a base station 105) may transmit a wideband signal (e.g., according to a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may include one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0110] The wireless communication system 100 may be an NR system that can utilize any combination of licensed, shared, and unlicensed spectrum bands. The flexibility of eCC symbol duration and subcarrier spacing may allow for the use of eCCs across multiple spectrums. In some examples, NR shared spectrum may improve spectrum utilization and efficiency, particularly through dynamic vertical (e.g., across the frequency domain) and horizontal (e.g., across the time domain) sharing of resources.

[0111] Some wireless communication systems may support UEs operating in DRX mode. The UE may transition between active and inactive states for data transmission and reception to conserve power. The DRX operating mode may be configured by the network based on a DRX cycle (or value). Conventional wireless communication systems, whether as part of a DRX mode or otherwise, may not account for inelastic data traffic between the UE 115 and the base station 105.

[0112] Therefore, as described herein, to reduce power consumption at UE 115, base station 105 may activate a periodic reception mode at the UE. In some cases, the periodic reception mode may be based on the latency tolerance of UE 115 and the throughput of the radio link associated with UE 115. In periodic reception mode, UE 115 may transition between an active state for data transmission and reception and an inactive state (such as an idle state or a "sleep" state). The active state may be referred to as a scheduling interval in periodic reception mode. The scheduling interval may be included in a scheduling cycle. In some cases, the remaining duration of the scheduling cycle may be referred to as an idle state. UE 115 may determine whether data is available by monitoring a control channel (such as a PDCCH) during the scheduling interval. The PDCCH may carry or otherwise convey an indication that base station 105 has data ready to transmit to UE 115 or is scheduling UE 115 for data transmission. In some cases, UE 115 may transition to idle mode at the end of the scheduling interval. Due to the high throughput of the wireless link associated with UE 115, base station 105 may determine that more than one data packet can be transmitted to UE 115 during the scheduling interval. That is, base station 105 may combine multiple packets and transmit the combined transmission as a data burst. As a result, UE 115 may sleep for a longer period of inactivity and may receive the combined data packet during the scheduling interval.

[0113] Figure 2 An example of a wireless communication system 200 that supports a periodic reception mode for wireless communication according to aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 may be an example of the wireless communication system 100 and may include a base station 105-a and a UE 115-a, which may be as described with reference to FIG. Figure 1Examples of corresponding wireless devices are described. Base station 105-a can provide network coverage for UE 115 within geographic coverage area 110-a. In some cases, UE 115-a can support a periodic reception mode to achieve improved power efficiency. According to some examples, UE 115-a can identify activation of the periodic reception mode. For example, UE 115-a can receive activation signal 215, which can indicate periodic scheduling to UE 115-a. UE 115 can be configured to monitor the control channel and sleep according to the periodic schedule.

[0114] In some cases, data traffic may be inelastic. In other words, the data arrival rate may not vary with the throughput of the radio link. In conventional systems, the base station may not consider the throughput of the radio link. That is, the rate at which the base station schedules data transmission for the UE may not vary with the throughput of the radio link between the base station and the UE. However, in mmW systems, the speed of the radio link may be greater than the data arrival rate. This may result in a waste of radio link bandwidth.

[0115] In conventional wireless communication systems, a DRX mode of operation may span the time period between consecutive "ON" states. A UE may determine whether data is available by monitoring a control channel, such as the PDCCH. The PDCCH may carry or otherwise convey an indication that the base station has data ready to transmit to the UE. Each data arrival indication may restart the DRX inactivity timer at the UE, which may reduce the amount of time the UE sleeps between two data reception windows. However, the DRX mode of operation may not be flexible enough to exploit the inelasticity of data traffic.

[0116] According to one or more aspects of the present disclosure, the base station 105-a may be able to activate a periodic reception mode. In some cases, to reduce the frequency of control channel monitoring, the base station (such as the base station 105-a) may be configured to buffer data and send the transmission data in bursts. This may result in an increase in the gaps between the data arrival windows at the UE (such as the UE 115-a). The increase in the gaps between the data arrival windows may increase power saving opportunities for the UE 115-a. For example, the base station 105-a may determine that the throughput of the wireless link is greater than a threshold and may activate the periodic reception mode at the UE 115-a. The base station 105-a may then transmit an activation signal 215 to the UE 115-a. For example, the base station 105-a may transmit the activation signal 215 on the downlink channel 205 (e.g., the downlink control channel). In some cases, the base station 105-a may aggregate multiple data packets and then transmit them to the UE 115-a. For example, the base station 105-a may aggregate a first packet and a second packet received after the first packet. In some cases, base station 105-a may form a single packet based on multiple packets, wherein the combined transmission includes the single packet. In some cases, base station 105-a may form a packet burst based on multiple packets, wherein the combined transmission includes the packet burst. Base station 105-a may then transmit the combined transmission to UE 115-a.

[0117] In a wireless communication system 200 (e.g., a mmW system), a UE 115-a may receive an activation signal from a base station 105-a and may determine activation of a periodic reception mode. The UE 115-a may then be configured to determine a periodic schedule associated with the periodic reception mode. The periodic schedule may include a duration of a scheduling interval and a duration of a scheduling cycle for the periodic reception mode. The UE 115-a may be configured to monitor a control channel according to the periodic schedule associated with the periodic reception mode. In some cases, the UE 115-a may monitor a control channel during a scheduling interval. For example, the UE 115-a may monitor a control channel for PDCCH reception during a scheduling interval. Additionally, the UE 115-a may be configured to sleep according to the periodic schedule associated with the periodic reception mode. For example, the UE 115-a may transition to a low power mode during a portion of the scheduling cycle.

[0118] To utilize the high throughput of the wireless link between the base station 105-a and the UE 115-a within the cell (e.g., the geographic coverage area 110-a), the base station 105-a may activate a periodic reception mode at the UE 115-4. The base station 105-a may multiplex multiple data packets so that available resources are efficiently used to support wireless communications with minimal power penalty.

[0119] Figure 3An example of a timing diagram 300 supporting a periodic receive mode for wireless communication according to aspects of the present disclosure is illustrated. In some examples, the timing diagram 300 can implement aspects of the wireless communication system 100. The timing diagram 300 can correspond to the timing diagram 300 described by reference to FIG. Figure 1 and Figure 2 The functionality performed by the UE 115 is described.

[0120] UE 115 may utilize a periodic reception mode for wireless communication to achieve power savings during periods of inactive traffic based on the latency requirements of UE 115. In some cases, timing diagram 300 corresponds to UE operation in a legacy wireless communication system. To further save power in wireless communication system 100 or 200, base station 105 may aggregate data packets and transmit the aggregated data packets as periodic bursts.

[0121] UE 115 (such as reference Figure 1 and Figure 2 15 may support delay-tolerant data traffic. UE 115 may operate in several different modes to support transmission and reception of data while achieving power conservation. For example, during an active duration (such as a duration of monitoring data), UE 115 may operate in a high or standard power mode (e.g., compared to a low power mode or "sleep" mode of UE 115). In some cases, UE 115 may be configured to receive an activation signal from base station 105 and identify a periodic schedule from the activation signal. UE 115 may then switch between monitoring a channel and sleeping according to the identified periodic schedule.

[0122] Timing diagram 300-a may illustrate a data transmission timeline in a conventional system, while timing diagram 300-b may illustrate a data transmission timeline according to one or more aspects of the present disclosure. In existing wireless communication systems, a base station may periodically transmit control channel signaling (such as PDCCH 315-a, 315-b, 315-c, or 315-d) and data packets or data 320 (such as 320-a, 320-b, 320-c, or 320-d). During active duration 305, UE 115 may receive downlink signals from base station 105. For example, during active duration 305, UE 115 may receive downlink data 320-a from base station 105. In some cases, UE 115 may transmit uplink data to base station 105 or perform any additional operations. In some cases, UE 115 may detect PDCCH 315-a signaling before receiving data 320-a from base station 105. After receiving data 320-a, UE 115 may remain in an inactive time period 310 after active duration 305. According to one or more aspects, UE 115 may initiate an inactive timer at the beginning of inactive time period 310 (i.e., at the end of active duration 305). During this inactive time period 310, if UE 115 receives an additional signal (e.g., a PDCCH signal) or transmits an additional signal before the inactive timer expires, UE 115 may re-enter the additional active duration 305 and may reset the inactive timer to restart at the end of the additional active duration 305. Otherwise, if the inactive timer expires, UE 115 may ramp down its power and enter a low power mode or "sleep" mode (e.g., a UE "off" duration). During the off duration, UE 115 may not transmit or receive signals.

[0123] Based on the configured DRX cycle, the UE 115 may periodically or aperiodically wake up from the low power mode into an on duration. During the on duration, the UE 115 may monitor the PDCCH 315 for any signaling transmitted to the UE 115. If the UE 115 does not detect any PDCCH signaling for the UE 115, the UE 115 may return to an off duration (i.e., return to sleep) for the remainder of the on duration after the on duration in which no PDCCH was detected in the DRX cycle. The UE 115 may then wake up in the next on duration and repeat the PDCCH monitoring. The length of time between each on duration may remain the same or may vary based on one or more timers.

[0124] Timing diagram 300-b may illustrate a data transmission timeline for a UE 115 supporting a periodic reception mode for inelastic and delay-tolerant data traffic. According to one or more aspects of the present disclosure, a base station 105 may aggregate multiple data packets to create a combined transmission. The base station 105 may then transmit the combined transmission to the UE 115. Figure 3 As described in

[0045] , the base station may periodically transmit control channel signaling (such as PDCCH 315-e) and data 320. To achieve additional power savings, the base station 105 may aggregate the first data 320-e and the second data 320-f. In some cases, the first data 320-e may arrive earlier than the second data 320-f. That is, if the base station 105 determines that the arriving data traffic is inelastic and the UE 115 is delay tolerant, the base station 105 may be configured to aggregate the data packets to create additional power saving opportunities at the UE 115. In some cases, the base station 105 may form a single packet based on multiple packets, wherein the combined transmission includes the single packet. In some cases, the base station 105 may form a packet burst based on multiple packets, wherein the combined transmission includes the packet burst. In some cases, the base station 105 may not buffer data traffic that is longer than the latency tolerance at the UE 115.

[0125] During active duration 305, UE 115 may receive downlink signals from base station 105. For example, during active duration 305, UE 115 may receive PDCCH 315-e indicating that data has arrived for UE 115. UE 115 may then receive aggregated downlink data 320-e and 320-f from base station 105. As an example, base station 105-a may receive data packets every 5 ms. Base station 105 may determine that the latency tolerance at UE 115 is 10 ms. In this case, base station 105 may determine to aggregate the data packets into bursts and transmit data bursts every 10 ms instead of every 5 ms. In some cases, after receiving aggregated data 320-e and 320-f, UE 115 may remain in an inactive time period 325 following active duration 305. As previously discussed, because the base station 105 aggregates multiple packets, the gap between receiving a PDCCH 315-e and a subsequent PDCCH 315-f is greater than in conventional wireless communication systems. In some cases, the UE 115 may initiate an inactivity timer at the beginning of the inactive time period 325 (i.e., the end of the active duration 305). Because the duration of the inactive time period 325 is greater than the duration of the inactive time period 310, the UE 115 may achieve power savings by remaining in a low power mode or "sleep" mode for a longer duration. Figure 3In the example shown in FIG. 1 , base station 105 aggregates two sets of data 320-e and 320-f, and the gap between receiving PDCCH 315-e and the subsequent PDCCH 315-f is twice the gap between receiving PDCCH 315-a and the subsequent PDCCH 315-b in a conventional wireless communication system. Thus, according to one or more aspects of the present disclosure, UE 115 can be configured to ramp down its power over a duration that is twice as long as that in a conventional wireless communication system. In this way, during longer periods of traffic inactivity, UE 115 can switch to a low-power mode to achieve significant power savings.

[0126] Figure 4 An example of a timing diagram 400 supporting a periodic reception mode for wireless communication according to aspects of the present disclosure is illustrated. In some examples, the timing diagram 400 may include a first timing diagram 400-a and a second timing diagram 400-b. In some cases, the first timing diagram 400-a and the second timing diagram 400-b may implement aspects of the wireless communication system 100. Various aspects of the timing diagram 400 may be implemented by a UE and / or a base station, which may be examples of corresponding devices described herein. In summary, the first timing diagram 400-a illustrates an example of a system supporting a DRX mode of operation and the second timing diagram 400-b illustrates an example of a system supporting a periodic reception mode for wireless communication.

[0127] In general, timing diagram 400-a illustrates timing diagrams associated with a base station 105 (such as referring to FIG. Figure 1 、 2 3 ). The default DRX value may be a network-configured DRX value transmitted in a broadcast message by a base station of the network. The broadcast message may include any combination of a Master Information Block (MIB) message, a System Information Block (SIB) message, a synchronization signal (such as a Primary Synchronization Signal (PSS) and / or a Secondary Synchronization Signal (SSS)), or any other message transmitted by the network. In some cases, the UE 115 (such as a base station described with reference to FIG. 3 ) may be sent during an RRC connection procedure. Figure 1 、 2 and 3) indicates the DRX value.

[0128] According to timing diagram 400-a, a default DRX value timing diagram can be associated with a DRX mode that includes transitions to active or "on" states 405 (such as 405-a, 405-b, 405-c, and 405-d), in which the UE 115 monitors paging messages from the base station 105, followed by inactive or idle states 410 (such as 410-a, 410-b, and 410-c), in which the UE can ramp down its power level. In some examples, the UE 115 can be configured to shut down various circuit systems, functions, and / or processes during the idle state 410 to save power. The DRX operating mode can have an associated default DRX value (also referred to as a DRX cycle 415). In some cases, the DRX cycle can be associated with the frequency at which the UE 115 transitions to the active state 405 (or "on" state 405). For example, a default DRX value may be measured between subsequent instances of the active state 405 (such as between "on" states 405-a and 405-b) or between subsequent instances of the idle state 410 (such as between idle states 410-a and 410-b). In some cases, the default DRX value or DRX cycle 415 may be configured by the network and indicated in a broadcast message. The DRX operating mode illustrated in timing diagram 400-a may not account for the inelastic traffic and throughput of the radio link between UE 115 and base station 105, and UE 115 may have to transition between active state 405 and idle state 410 when new data arrives. Each instance in which UE 115 transitions between idle state 410 to active state 405 and then back to idle state 410 may incur additional power usage at the UE.

[0129] According to one or more aspects of the present disclosure, timing diagram 400-b illustrates a timing diagram associated with a periodic reception mode for wireless communication. In some cases, the periodic reception mode may be based on a periodic schedule indicated by a base station. In some cases, the periodic schedule may indicate the duration of an active state, an inactive state, and an inactive timer. Figure 4 In an example, timing diagram 400-b may be associated with a periodic reception mode that includes transitions to active states 420 (such as 420-a and 420-b) in which UE 115 monitors for paging messages from a base station, followed by an idle state in which the UE ramps down its power level.

[0130] In some cases, the active state 420 in periodic scheduling may be referred to as a scheduling interval 420, and the inactive state in periodic scheduling may be referred to as a portion of a scheduling cycle 425. In some cases, the scheduling cycle 425 may be associated with the frequency with which the UE 115 transitions to the active state 420. For example, the scheduling cycle 425 may be measured between subsequent instances of the scheduling interval 420 or active state (such as between a first scheduling interval 420-a and a second scheduling interval 420-b) or between subsequent instances of the inactive state or scheduling cycle 425 (not shown). In some cases, the scheduling interval 420 may be a portion of the scheduling cycle 425. For example, the UE 115 may be configured to monitor PDCCH resources during the scheduling interval 420 and may transition to a "sleep" mode during the remainder of the scheduling cycle 425.

[0131] The periodic reception operating mode may additionally have an associated periodic reception inactivity timer (not shown). In some cases, the UE 115 may initiate an inactivity timer at the beginning of the inactivity time period (i.e., the end of the scheduling interval 420). During this inactivity time period, if the UE 115 receives an additional signal before the periodic reception inactivity timer expires, the UE 115 may re-enter an additional activity duration 420-b (such as an additional scheduling interval 420-b). The UE 115 may then reset the periodic reception inactivity timer to restart at the end of this activity duration 420-b. In some cases, the value of the periodic reception inactivity timer may be set to "0". That is, in the periodic reception mode, because the periodic reception inactivity timer is set to "0", the UE 115 may power off and transition to "sleep" mode immediately after the scheduling interval 420 ends. As previously described with reference Figure 3 As described, the base station 105 may be configured to buffer data traffic during periods when the UE is in "sleep" mode. The base station 105 may then transmit multiple data packets (such as a combined data packet) during a transmission opportunity. In some cases, data transmission may occur in one or more transmission blocks.

[0132] According to one or more aspects of the present disclosure, UE 115 may receive an activation signal for a periodic reception mode. In some cases, the activation signal may be received as a MAC layer control element indicating activation of the periodic reception mode. In some aspects, the activation signal may be included in a DCI. Additionally or alternatively, UE 115 may receive the activation signal as part of an RRC configuration message. UE 115 may identify a periodic schedule in the activation signal. In some cases, the periodic schedule may indicate the duration and / or periodicity of the scheduling interval 420 and the scheduling cycle 425. In some cases, upon receiving the periodic schedule, UE 115 may be configured to monitor the channel and sleep according to the periodic schedule.

[0133] In some cases, the UE 115 may receive an indication to activate a periodic reception mode. As previously discussed, the periodic reception mode may include durations for the scheduling interval 420 and the scheduling cycle 425. In some cases, the duration of the scheduling interval 420 may be fixed. In some cases, the duration of the scheduling interval 420 may be configured by the network based on the scheduling load at the base station 105. In some cases, the duration of the scheduling cycle 425 may be fixed. The duration of the scheduling cycle 425 may be configured by the network or recommended by the UE 115.

[0134] In some cases, the UE 115 may estimate the arrival rate of data packets and may provide a recommendation for the duration of the scheduling cycle 425. That is, the UE 115 may determine recommended values for parameters associated with the periodic scheduling. In some cases, the recommended values may include: a recommended duration for the scheduling interval 420 for the periodic reception mode, a recommended duration for the scheduling cycle 425 for the periodic reception mode, a recommended duration for the periodic reception inactivity timer for the periodic reception mode, or any combination thereof. In some aspects, the UE 115 may indicate the recommended values for the parameters to the base station 105.

[0135] According to one or more aspects of the present disclosure, the UE 115 may receive an indication of the duration of the scheduling interval 420 for monitoring a control channel while in periodic reception mode. Figure 4 As shown, scheduling interval 420 may be a subset of scheduling cycle 425 for a periodic reception mode. In some cases, UE 115 may determine a recommended duration for scheduling cycle 425 based on the duration of scheduling interval 420, the throughput of a radio link associated with base station 105, the data arrival rate at base station 105, and the latency tolerance of an application associated with the data. UE 115 may receive a value for scheduling interval (T0) from base station 105. UE 115 may also determine an estimated throughput (S) and an estimated / measured data arrival rate (X) for the radio link. In some cases, for example, UE 115 may determine the radio throughput (S) based on the modulation and coding scheme (MCS) used for the associated radio link. As another example, UE 115 may determine the estimated / measured data arrival rate (X) based on the data arrival rate at UE 115 (e.g., UE 115 may assume that the data arrival rate at base station 105 is equal to the data arrival rate at UE 115). In some cases, the UE 115 may determine the duty cycle (S / X) as the ratio between the throughput (S) of the radio link and the data arrival rate (X). In some examples, the UE 115 may be configured to determine the recommended duration of the scheduling cycle 425 based on the application delay requirement value (Tr) and the product of the scheduling interval (T0) and the duty cycle (S / X).

[0136] In some cases, the UE 115 may determine that the recommended duration of the scheduling cycle 425 is less than the latency tolerance at the UE 115. Upon determining that the recommended duration of the scheduling cycle 425 is less than the latency tolerance, the UE 115 may recommend to the base station 105 that the total bandwidth be increased. For example, the UE 115 may recommend bandwidth fractional switching, additional carriers, or a combination. This may be beneficial to the UE 115 because the increased bandwidth may cause the scheduling cycle 425 to be extended to the latency tolerance (such as the delay requirement), thereby increasing power savings at the UE 115. In some cases, the UE 115 may be configured to select the total bandwidth for downlink transmissions and the total bandwidth for uplink transmissions such that both downlink and uplink transmissions have the same duty cycle. In some cases, the UE 115 may also indicate the antenna(s) to be used for upcoming communications as part of the recommendation parameters. In some aspects, the UE 115 may determine that the recommended duration of the scheduling cycle 425 is greater than the latency tolerance. In this case, UE 115 may transmit a request to base station 105 for reduced bandwidth.

[0137] In some aspects, the periodic reception mode can be configured independently of the conventional DRX mode. UE 115 can be configured with a periodic reception mode that is independent of the DRX mode. The periodic reception mode may be particularly beneficial to UE 115 associated with more traffic. In some cases, UE 115 can be configured with both the periodic reception mode and the DRX mode. In some cases, UE 115 can restart the periodic reception inactivity timer when receiving a data packet. However, if UE 115 does not receive any data before the periodic reception inactivity timer expires, UE 115 can be configured to switch from the periodic reception mode to the DRX mode. In some cases, the DRX mode may not be configured at UE 115. In this case, the periodic reception inactivity timer may not be used. Additionally or alternatively, the periodic reception inactivity timer can reuse the same DRX inactivity timer. It is started when the periodic reception mode is activated and restarted at each new data transmission / reception.

[0138] Typically, UE 115 may receive a MAC control element and may dynamically switch to periodic reception mode. In some cases, base station 105 may indicate activation of DRX mode during RRC configuration and may use a MAC control element to indicate activation of periodic reception mode. In some cases, UE 115 may have already been configured with the duration of a scheduling interval 420 and a duration of a scheduling cycle 425 (such as during an RRC procedure). Upon receiving the MAC control element, UE 115 may activate periodic reception mode and begin monitoring the channel according to the scheduling interval 420. In some cases, if a change in data traffic pattern is detected at base station 105, base station 105 (or the network) may change parameters associated with periodic reception mode (such as scheduling interval 420 and scheduling cycle 425) based on the change in traffic pattern. In some cases, base station 105 may transmit an indication of the change to UE 115 using a MAC control element. In some cases, periodic reception mode may be activated and deactivated by DCI. In some cases, the information element may be used to configure a periodic reception mode at the UE 115. In some cases, the information element may include a field for a scheduling interval, a field for a scheduling cycle, and a field for a periodic reception inactivity timer. In some cases, the field for the periodic reception inactivity timer may be optional. The fields of the information element may be in units of time (e.g., milliseconds).

[0139] In some cases, a periodic reception inactivity timer may be enabled when periodic reception mode is activated and restarted with each new data transmission / reception. UE 115 may deactivate periodic reception mode by receiving a deactivation signal in a MAC control element or by expiration of a periodic reception inactivity timer. Upon deactivation of periodic reception mode, UE 115 may be configured to return to continuous monitoring mode.

[0140] In some cases, UE 115 may be configured with both periodic reception mode and DRX mode. In this case, MAC control may be used to activate both periodic reception mode and DRX mode. Activation of periodic reception mode may be performed within DRX mode or continuous monitoring mode. In some cases, UE 115 may be configured to use a DRX inactivity timer for periodic reception mode. Upon deactivation of periodic reception mode, UE 115 may transition to DRX mode. In some examples, UE 115 may receive a wake-up signal indicating the presence of data for the UE. UE 115 may be configured to monitor a control channel according to a periodic schedule and based on the wake-up signal. In this case, upon receiving the wake-up signal, UE 115 may be configured to wake up and monitor the control channel during the next on-duration. In periodic reception mode, base station 105 may transmit a wake-up signal at the beginning of a scheduling interval 420. If the wake-up signal (or the absence of a wake-up signal) indicates that no data is scheduled for UE 115, UE 115 may be configured to skip the next scheduling interval 420.

[0141] In some cases, the UE 115 may be configured to receive an indication of a HARQ configuration for a periodic reception mode. In some cases, identifying the activation of the periodic reception mode may include an indication of the HARQ configuration for the periodic reception mode. Upon receiving the indication, the UE 115 may identify HARQ transmissions associated with the scheduling interval 420 of the periodic reception mode and may communicate with the base station based on the HARQ configuration for the periodic reception mode.

[0142] In some cases, communicating based on the HARQ configuration includes extending the scheduling interval 420 to accommodate HARQ transmissions (e.g., the UE 115 may continue its existing HARQ retransmissions after the end of the scheduling interval) or exchanging HARQ transmissions with the base station during a subsequent scheduling interval (e.g., the UE 115 may defer any pending HARQ retransmissions to the next scheduling interval). In some cases, which HARQ behavior the UE 115 should follow may be configured by the network (e.g., via signaling such as an activation signal, which the UE 115 may receive from the base station 105). Thus, in some cases, HARQ retransmissions may be configured to continue after the scheduling interval 420. That is, if there is an ongoing transmission after the scheduling interval 420, the UE 115 may be configured to complete the ongoing transmission before transitioning to "sleep" mode. In some cases, periodic and / or aperiodic channel state information (CSI) reports may be sent outside the duration of the scheduling interval 420.

[0143] During the periodic reception mode, UE 115 may transmit a scheduling request during a first scheduling interval. In some cases, the scheduling request may include a request to schedule uplink transmissions during the first scheduling interval or during a second scheduling interval of the periodic reception mode following the first scheduling interval. In some cases, UE 115 may determine when to transmit the scheduling request based on UE implementation. More specifically, UE 115 may determine whether the scheduling request can be delayed until the next scheduling interval 420 based on a latency tolerance at UE 115.

[0144] In some cases, the random access procedure may override one or more operations of the periodic reception mode. In some cases, the grant of the uplink configuration may be aligned with the scheduling interval 420 of the periodic reception mode. Alternatively, the grant of the uplink configuration may operate independently of the operation of the periodic reception mode.

[0145] Figure 5 An example of a process flow 500 for supporting a periodic reception mode for wireless communication according to aspects of the present disclosure is illustrated. In some examples, the process flow 500 can implement aspects of the wireless communication system 100. The process flow 500 can include a base station 105-b and a UE 115-b, which can be referenced. Figures 1 to 4 Examples of corresponding devices described herein. UE 115-b and base station 105-b may support a periodic reception mode for wireless communications to achieve power conservation. UE 115-a may be configured (e.g., preconfigured or configured by base station 105-b) to operate in the periodic reception mode to efficiently utilize available resources in the system.

[0146] In the following description of process flow 500, operations between UE 115-b and base station 105-b may be communicated in an order different from the exemplary order shown. Operations performed by UE 115-b or base station 105-b may be performed in an order different from the exemplary order shown or at different times. Some operations may also be excluded from process flow 500, or other operations may be added to process flow 500. Furthermore, UE 115-b and base station 105-b are not intended to be representative, as the features described may be associated with any number of devices.

[0147] At 505, the base station 105-b may transmit an activation signal for the periodic reception mode. In some cases, before transmitting the activation signal, the base station 105-b may identify the activation of the periodic reception mode for the UE 115-b. The activation signal may indicate to the UE 115-b to activate the periodic reception mode. In some cases, the base station 105-b may transmit the activation signal using a MAC layer control element. In some cases, the base station 105-b may transmit the activation signal using a DCI. In some cases, the base station 105-b may transmit the activation signal using RRC configuration signaling. Additionally, the RRC configuration signaling may configure the UE 115-b with a set of parameters associated with the periodic reception mode.

[0148] At 510, UE 115-b may identify a periodic schedule, which may include identifying a set of parameters (e.g., scheduling parameters) associated with the periodic reception pattern. In some cases, the set of parameters associated with the periodic reception pattern may include a scheduling interval and a scheduling cycle. At block 515, UE 115-b may determine a duration of a scheduling interval for the periodic reception pattern based on the received activation signal. In some cases, the duration of the scheduling interval may be configured by base station 105-b and may be based on a scheduling load at base station 105-b.

[0149] At block 515, UE 115-b may determine a duration of a scheduling cycle for the periodic reception pattern based on the received indication. In some cases, the scheduling cycle may include a corresponding scheduling interval. In some cases, UE 115-b may be configured to monitor for data and / or control information according to the scheduling interval included in the scheduling cycle and may sleep for the remainder of the scheduling cycle.

[0150] At block 520, UE 115-b may monitor the control channel according to a periodic schedule associated with the periodic reception mode. In some cases, UE 115-b may monitor the control channel based on receiving an activation signal for the periodic reception mode. In some examples, UE 115-b may monitor the control channel according to the scheduling interval determined at 515.

[0151] At 530, base station 105-b may identify data for communication with UE 115-b. In some cases, base station 105-b may aggregate multiple packets to create a combined transmission. In some cases, the packets may include at least a first packet and a second packet received after the first packet. In some cases, base station 105-b may form a single packet based on the multiple packets, wherein the combined transmission includes the single packet. In some cases, base station 105-b may form a packet burst based on the multiple packets, wherein the combined transmission includes the packet burst. In some cases, before aggregating, base station 105-b may determine a data arrival rate for UE 115-b based on a time difference between receiving the first packet and the second packet. Base station 105 may then determine that the data arrival rate for UE 115-b is less than the throughput of the wireless link associated with UE 115-b. In this case, base station 105-b may aggregate the data packets to enhance power conservation at the UE.

[0152] At 535, the base station 105-b may transmit the combined transmission to the UE 115-b according to a periodic schedule associated with the periodic reception pattern. That is, the base station 105-b may transmit the combined transmission during a scheduled interval of the periodic reception pattern.

[0153] At block 540, UE 115-b may receive the combined transmission according to the periodic schedule. In some cases, UE 115-b may receive the combined transmission during a scheduled interval of the periodic reception mode. At 545, UE 115-b may initiate a sleep procedure. In other words, UE 115-b may operate according to a low power mode. For example, UE 115-b may "sleep" and may not transmit or receive data in this low power mode. UE 115-b may periodically continue to monitor for data during subsequent scheduled intervals.

[0154] Figure 6 Diagram 600 illustrates a device 605 that supports a periodic receive mode for wireless communication according to aspects of the present disclosure. The device 605 may be an example of aspects of the UE 115 as described herein. The device 605 may include a receiver 610, a communication manager 615, and a transmitter 620. The device 605 may also include a processor. Each of these components may be in communication with each other (e.g., via one or more buses).

[0155] The receiver 610 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to periodic reception patterns for wireless communications). The information may be passed to other components of the device 605. The receiver 610 may be a reference Figure 9Examples of aspects of the described transceiver 920. The receiver 610 may utilize a single antenna or a collection of antennas.

[0156] The communication manager 615 may identify activation of a periodic reception mode. In some cases, the communication manager 615 may receive an activation signal for the periodic reception mode. The communication manager 615 may monitor a control channel according to a periodic schedule associated with the periodic reception mode based on identifying activation of the periodic reception mode, and sleep according to the periodic schedule associated with the periodic reception mode based on identifying activation of the periodic reception mode. The communication manager 615 may be an example of aspects of the communication manager 910 described herein.

[0157] The communication manager 615 or its subcomponents may be implemented in hardware, in code executed by a processor (e.g., software or firmware), or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 615 or its subcomponents may be performed by 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 designed to perform the functions described in this disclosure, discrete gate or transistor logic, discrete hardware components, or any combination thereof.

[0158] The communication manager 615 or its subcomponents can be physically located at various locations, including being distributed such that portions of the functionality are implemented by one or more physical components at different physical locations. In some examples, according to various aspects of the present disclosure, the communication manager 615 or its subcomponents can be separate and distinct components. In some examples, according to various aspects of the present disclosure, the communication manager 615 or its subcomponents can be combined with one or more other hardware components (including, but not limited to, input / output (I / O) components, a transceiver, a network server, another computing device, one or more other components described in the present disclosure, or a combination thereof).

[0159] The transmitter 620 may transmit signals generated by other components of the device 605. In some examples, the transmitter 620 may be co-located with the receiver 610 in a transceiver module. For example, the transmitter 620 may be a reference Figure 9 Examples of aspects of the described transceiver 920. The transmitter 620 may utilize a single antenna or a collection of antennas.

[0160] Figure 7A diagram 700 is shown of a device 705 that supports a periodic receive mode for wireless communication according to aspects of the present disclosure. The device 705 can be an example of aspects of the device 605 or UE 115 as described herein. The device 705 can include a receiver 710, a communication manager 715, and a transmitter 735. The device 705 can also include a processor. Each of these components can be in communication with each other (e.g., via one or more buses).

[0161] The receiver 710 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to periodic reception patterns for wireless communications). The information may be passed to other components of the device 705. The receiver 710 may be a reference Figure 9 Examples of aspects of the described transceiver 920. The receiver 710 may utilize a single antenna or a collection of antennas.

[0162] Communications manager 715 may be an example of aspects of communications manager 615 as described herein. Communications manager 715 may include signal receiving component 720, monitoring component 725, and sleeping component 730. Communications manager 715 may be an example of aspects of communications manager 910 as described herein.

[0230] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with a network provider. A small cell may be associated with a lower-power base station (compared to a macro cell), and may operate in the same or different frequency bands (e.g., licensed, unlicensed, etc.) as the macro cell. According to various examples, small cells may include pico cells, femto cells, and micro cells. A pico cell, for example, may cover a smaller geographic area and may allow unrestricted access by UEs with service subscriptions with a network provider. A femto cell may also cover a smaller geographic area (e.g., a residence) and may provide restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG), UEs of users in the residence, etc.). An eNB for a macro cell may be referred to as a macro eNB. An eNB for a small cell may be referred to as a small cell eNB, a pico eNB, a femto eNB, or a home eNB.

The techniques described herein can be used for either synchronous or asynchronous operation.

[0232] The information and signals described herein may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referred to throughout this description may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof.

[0233] The various illustrative blocks and modules described in conjunction with the disclosure herein may be implemented or executed with a general purpose processor, a DSP, an ASIC, an FPGA or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. A general purpose processor may be a microprocessor, but in the alternative, the processor may be any 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, a plurality of microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0234] Computer-readable media include both non-transient computer storage media and communication media, including any medium that facilitates a computer program to be transferred from one place to another. Non-transient storage media can be any available medium that can be accessed by a general or special-purpose computer. As an example and not limitation, non-transient computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compact disc (CD) ROM or other optical disc storage, magnetic disk storage or other magnetic storage device, or any other non-transient medium that can be used to carry or store the desired program code means of an instruction or data structure form and can be accessed by a general or special-purpose computer or a general or special-purpose processor. Any connection is also properly referred to as a computer-readable medium. For example, if 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, radio, and microwaves, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwaves are included in the definition of medium. Disk and disc, as used herein, include CDs, laser discs, optical discs, digital versatile discs (DVDs), floppy disks, and Blu-ray discs, where disks usually reproduce data magnetically, while discs reproduce data optically with lasers. Combinations of the above are also included within the scope of computer-readable media.

[0235] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, each function may be stored on or transmitted by a computer-readable medium as one or more instructions or codes. Other examples and implementations fall within the scope and spirit of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein may be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination thereof. Features implementing the functions may also be physically located in various locations, including being distributed so that parts of the functions are implemented at different physical locations. As used herein (including in the claims), the term "and / or" used in a listing of two or more items means that any of the listed items may be employed individually, or any combination of two or more listed items may be employed. For example, if a composition is described as comprising components A, B, and / or C, the composition may comprise only A; only B; only C; a combination of A and B; a combination of A and C; a combination of B and C; or a combination of A, B, and C. Similarly, as used herein (including in the claims), “or” used in a list of items (e.g., in a list of items followed by a phrase such as “at least one of” or “one or more of”) indicates a disjunctive list so that, for example, a list “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).

[0236] In the accompanying drawings, similar components or features may have the same reference number. In addition, components of the same type may be distinguished by following the reference number with a dash and a second reference number that distinguishes between the similar components. If only the first reference number is used in the specification, the description applies to any of the similar components having the same first reference number, regardless of the second reference number or other subsequent reference numbers.

[0237] The description set forth herein in conjunction with the accompanying drawings describes example configurations and does not represent all examples that can be implemented or fall within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration" and does not mean "better than" or "better than other examples."
