Description

Technical Field

[0001] This disclosure is generally directed to wireless communications. In particular, this disclosure relates to methods, apparatus, and systems for transmitting and receiving signals for power management. Background Technology

[0002] Wireless communication technology is propelling the world towards an increasingly interconnected and networked society. High-speed, low-latency wireless communication relies on efficient network resource management and allocation between one or more user devices and one or more wireless access network nodes (including but not limited to base stations). Next-generation networks promise to provide high-speed, low-latency, and ultra-reliable communication capabilities, meeting the needs of various industries and users.

[0003] With the rapid development of cellular mobile communication systems, the power consumption of next-generation wireless base stations has increased significantly. For example, compared to 4G base stations, 5G base stations consume several times more power due to the increased number of transmit / receive antennas and frequency bands. Improving network energy efficiency is crucial for building green and sustainable wireless communication systems. However, some energy-saving solutions may have many problems and controversies, such as causing high latency and impacting user experience.

[0017] This disclosure will now be described in detail below with reference to the accompanying drawings, which form a part of this disclosure and illustrate specific examples of embodiments by way of illustration. However, it should be noted that this disclosure may be embodied in various different forms, and therefore the subject matter covered or claimed is intended to be construed as not being limited to any of the embodiments set forth below.

Similarly, the phrases “in one embodiment” or “in some embodiments” as used herein do not necessarily refer to the same embodiment, and the phrases “in another embodiment” or “in other embodiments” as used herein do not necessarily refer to different embodiments. For example, the claimed subject matter is intended to include, in whole or in part, exemplary embodiments or combinations of embodiments.

[0019] Generally, terms can be understood at least in part from their use in context.

[0020] This disclosure describes various methods and apparatus for transmitting and receiving signals for power management.

[0021] Next-generation (NG) mobile communication systems are propelling the world towards an increasingly connected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between one or more user devices and one or more wireless access network nodes (including but not limited to wireless base stations). NG networks promise to provide high-speed, low-latency, and ultra-reliable communication capabilities, meeting the needs of various industries and users.

[0022] With the rapid development of cellular mobile communication systems, wireless base stations or wireless network nodes are consuming increasingly more electricity. For example, compared to 4G base stations, 5G base stations consume 3 to 4 times more power due to the increased number of transmit / receive antennas and frequency bands. Improving network energy efficiency is crucial for building green and sustainable wireless communication systems.

[0023] To achieve power-saving gains, some implementations can configure the network to deactivate / disable certain components (e.g., cells, carriers, frequency bands, etc.) to enter a sleep or low-power state. However, semi-static wake-up schemes can lead to significant latency and negatively impact user experience. Information transmitted from the UE to the network can help the base station make better power-saving decisions and quickly adjust its state. This disclosure describes various methods and apparatuses for transmitting and receiving signals for power management, providing more flexible wake-up mechanisms and ensuring that the network and UE have the same understanding of power-saving operations, thus avoiding impacts on user experience.

[0024] Typically, the power consumption of a communication system can be divided into two parts: dynamic and static. Generally, the dynamic part is consumed only when data transmission / reception is in progress, such as the power consumption caused by radio frequency (RF) units, digital-to-analog converters (DACs), power amplifiers (PAs), and / or antennas. Even when data transmission / reception is not in progress, the static part may still be consumed, for example, by basic digital circuitry connected to a device used to wake up a device in sleep mode.

[0025] Switching to sleep mode or shutting down some RF components when they are not needed are effective methods to reduce network power consumption. For example, carriers can be deactivated if there is no UE access. The number of Tx / Rx antennas can be reduced when traffic load is low. However, there are some problems with using this power-saving method. First, there are some common signals and necessary transmissions in the new radio (NR), such as synchronization signal block (SSB), system information block (SIB), paging, and physical random access channel (PRACH) reception. Therefore, the network may not easily enter a low-power state (e.g., sleep mode). Second, even if the device can enter a sleep state, waking the device is a problem. If a semi-static configuration is used, the device may only be woken up after a period of sleep. If there is a service demand while the device is in a sleep state, the resulting latency may prevent the service demand from being met, thus affecting the user experience.

[0026] In various embodiments, the network may be able to enter a low-power state for as long as possible to reduce the power consumption of the communication system; a more dynamic wake-up mechanism may be introduced to meet flexible service needs and minimize the impact on user experience; and / or one or more UEs may participate in the process to achieve better results. Furthermore, the network provides responses to the UE, notifying the UE of operations, states, or configurations to achieve consensus between the network and the UE and minimize the impact on the UE.

[0027] Figure 1 A wireless communication system 100 is illustrated, comprising a wireless network node 118 (also referred to as a wireless network base station 118) and one or more user equipment (UE) 110. The wireless network node may include a network base station, which may be a nodeB (NB, e.g., gNB, eNB) in a mobile telecommunications context. Each UE may wirelessly communicate with the wireless network node via one or more radio channels 115. For example, a first UE 110 may wirelessly communicate with the wireless network node 118 via a channel including multiple radio channels during a specific time period. The wireless network base station 118 may send higher-layer signaling to the UE 110. The higher-layer signaling may include configuration information for communication between the UE and the base station. In one embodiment, the higher-layer signaling may include radio resource control (RRC) messages.

[0074] First information transmitted by UE

[0075] In some embodiments, the UE transmits an initial channel and / or reference signal to the base station, wherein the initial channel and / or reference signal is used for measurement or to carry initial information.

[0082] In some embodiments, the base station sends a response to the UE after receiving initial data and / or a reference signal, regardless of the information. In some other embodiments, whether the base station sends a response is related to first information transmitted by the UE. For example, the base station sends a response to the UE when the first information transmitted by the UE indicates or determines a second power state.

In some other embodiments, the base station sends a response to the UE if the power state is determined by a measurement result obtained by the base station or a measurement result carried by the initial data and / or the reference signal. For example, the base station sends a response to the UE when the second power state is determined by a measurement result obtained by the base station. Or, the base station sends a response to the UE when the power state of the base station changes.

[0083] In some other embodiments, the information received by the UE includes at least one of the following: ACK / NACK indication; operation indication; and / or information for an element; timing advance (TA) command; and / or handover command.

Or, ACK indicates that the gNB performed the operation indicated by the information sent by the UE, and / or NACK indicates that the gNB did not perform the operation indicated by the information sent by the UE.

[0085] In some embodiments, the information received by the UE includes an instruction for operation. The instruction for operation includes at least one of the following: power state, such as a first power state and a second power state; wake-up operation; and information about an element, such as the configuration of the element.

[0086] In some other embodiments, the UE receives a gNB response in at least one of the following: a first cell in which the UE transmits information; or a second cell in which the UE transmits information in the first cell.

[0087] By receiving responses from the gNB, the UE can maintain the same understanding as the gNB, allowing the UE to be switched to a more appropriate configuration in a timely manner. This feature minimizes the impact on the UE experience while reducing the gNB's power consumption.

[0088] The timing of information from the base station

[0089] In some implementations, the information transmitted by the base station (gNB) is monitored by the UE in a set of monitoring opportunities.

[0090] In some other implementations, the information transmitted by the base station (gNB) is monitored by the UE in a set of monitoring opportunities during the reception window.

[0091] In some embodiments, the timing of monitoring information transmitted by a base station (gNB) is determined by a receiving window and a predetermined search space.

[0092] In some other embodiments, the monitoring timing or receiving window is determined by at least one of the following methods.

[0093] One method includes at least one of the following: a start point, a duration, and an end point. The start point or end point is determined by at least one of the following: the time position of the reference signal / data (carrying the first information) transmitted by the UE (e.g., the symbol / time slot / subframe / frame when the UE transmits the reference signal / data); and / or an offset.

[0094] In some other embodiments, the start point or end point is defined relative to at least one of the following: SSB, SSS, PSS, discovery reference signal (DRS), TRS, PO, PEI, DCI 2_6, reference signal / data transmitted by the UE, and / or a first window associated with the reference signal / data transmitted by the UE.

[0095] In some other embodiments, the duration is determined by at least one of the following: higher-layer signaling, UE capabilities, SCS, frequency range, predetermined value (e.g., fixed value), or timer.

[0096] Another approach involves periodicity. In some implementations, the timing of information transmission by the gNB is periodic.

[0097] Another approach involves determining the occurrence of a response (information) transmitted by the base station through at least one of the following: an indication / information sent by the UE; a measurement result of a reference signal sent by the UE; UE capabilities; higher-layer signaling; SCS; and / or frequency range.

[0098] In some implementations, the response (information) to an indication / information sent by the UE may occur when the indication / information sent by the UE indicates or determines a wake-up operation or a non-power-saving state (first power state). In some other implementations, the response (information) may occur when the indication / information sent by the UE indicates or determines a power-saving state (second power state).

[0099] In some implementations, the indications / information sent by the UE may include at least one of the following: assistance information, mobility information, RRM measurement information, or coverage information. For example, if the assistance information sent by the UE indicates that the gNB needs to be woken up, the gNB will transmit a response (such as an operation instruction, TA command, or handover command).

[0100] For example, regarding the measurement result of the reference signal sent by the UE, in response to the measurement result of the reference signal being lower than a predetermined value, a response (information) may occur, and the gNB transmits the response (such as an operation instruction, TA command, or handover command).

[0101] For example, regarding higher-layer signaling, whether the base station transmits a response is determined at least by higher-layer signaling.

[0102] In some other implementations, the UE monitors responses / information sent by the gNB under given conditions. These given conditions are related to at least one of the following: indications / information sent by the UE, channel quality, period, number of receptions, or maximum number of receptions.

[0103] In some embodiments, the given condition is related to an indication / information sent by the UE. In some embodiments, the indication / information sent by the UE may include a status transmission or a wake-up indication. For example, when the UE sends wake-up or non-power-saving state-related information, the UE monitors the information sent by the gNB. In some embodiments, when the UE sends power-saving state-related information, the UE monitors the information sent by the gNB. In some other embodiments, the indication information includes at least one of the following: assistance information, mobility information, RRM measurement information, or coverage information. For example, the UE may send RRM measurement information, indicating that the RSRP sent by the UE to the gNB is lower than a preset value, and the UE monitors the information sent by the gNB.

[0104] In some embodiments, the given conditions are related to channel quality. In some embodiments, channel quality is determined by at least one of the following: RSRP (Reference Signal Received Power), RSRQ (Reference Signal Received Quality), RSSI (Reference Signal State Information), SINR (Signal-to-Interference-plus-Noise Ratio), L1-RSRP, and L1-SINR. In some embodiments, the UE begins to detect a response when at least one channel quality is within a certain range.

[0105] In some other embodiments, the given condition is related to a period. The UE periodically checks whether a response has been transmitted. In some other embodiments, the given condition is determined by an indication / information sent by the UE and the period. When the first information transmitted by the UE satisfies the condition, the UE begins to detect a response and periodically checks for responses.

[0106] In some other embodiments, the given condition is related to a maximum number of receptions. The UE monitors the response before the maximum number of receptions is reached.

[0107] In some other implementations, the UE monitors the response / information sent by the gNB after transmitting the first information to the base station, regardless of what information the UE transmits.

[0108] Frequency resources of information transmitted by base stations

[0109] In some implementations, the frequency resources for information transmitted by a base station (gNB) can be determined by at least one of the following methods.

[0110] One method for determining the frequency resources of information is based on higher-level signaling.

[0111] Another method for determining the frequency resources of information is based on the start and / or end positions in the frequency domain. The start / end position in the frequency domain is defined relative to at least one of the following: common resource block #0; point A; SSB, for example, the reference point is the lowest RB(RE) of the SSB; CORESET 0, for example, the reference point is the lowest RB(RE) of CORESET 0; active BWP, for example, the reference point is the lowest RB(RE) of the active BWP; and / or reference signals / data transmitted by the UE, for example, the reference point is determined by the frequency resources of the reference signals / data transmitted by the UE.

[0112] Another way to determine the frequency resources of information is based on the number of RBs. The number of RBs can be determined by a bitmap or the configuration of RBs (e.g., a configuration of consecutive RBs).

[0113] Another method for determining the frequency resources for information is based on at least one of the following: SSB, CORESET 0, active BWP, or initial UL BWP. For example, a UE cannot transmit data / reference signals outside the frequency range of SSB, CORESET, active BWP, or initial UL BWP.

[0114] Spatial information of the response sent by the base station

[0115] In some other implementations, the spatial information of the data / reference signal is determined by at least one of the following: SSB, TRS, PEI, paging DCI and / or reference signal / data transmitted by the UE.

[0116] In some embodiments, data / reference signals are transmitted using multiple beams or quasi-colocation (QCL) information having the same beam direction as a predetermined downlink signal or channel. The predetermined downlink signal or channel includes at least one of the following: SSB, TRS, PEI, and paging DCI. In some embodiments, data / reference signals are transmitted using the same beam direction as the predetermined downlink signal or channel for each beam direction. In some embodiments, the same content is used to transmit data / reference signals for each beam direction. In some embodiments, different scrambling codes are used to transmit data / reference signals for each beam direction. In some embodiments, the scrambling code is associated with the predetermined downlink signal or channel.

[0117] In some embodiments, quasi-co-address (QCL) information of data / reference signals is associated with a predetermined downlink signal or channel.

[0118] In some embodiments, the beam direction or quasi-co-address (QCL) information of the data / reference signal is associated with the reference signal / data transmitted by the UE. For example, the transmission resources of the reference signal / data transmitted by the UE are associated with a predetermined downlink signal or channel. The data / reference signal transmitted by the base station has the same beam direction or quasi-co-address (QCL) information as the predetermined downlink signal or channel associated with the transmission resources of the reference signal / data transmitted by the UE.

[0119] The format of information transmitted by the base station

[0120] This information is carried by at least one of the following messages.

[0121] In some implementations, this information is carried by a message B-based channel. The message B-based channel is used to carry the aforementioned information transmitted by the base station, and a typical message B for initial access is distinguished by at least one of the following: time-domain resource allocation; frequency-domain resource allocation; or a message A-based channel transmitted by the UE.

[0122] In some other implementations, the information transmitted by the base station is carried by a DCI. The DCI is a DCI with a CRC scrambled by at least one of the following: PS-RNTI (Power Saving-Temporary Identifier for Radio Networks), P-RNTI (Paging-Temporary Identifier for Radio Networks), SI-RNTI (System Information-Temporary Identifier for Radio Networks), RA-RNTI (Random Access-Temporary Identifier for Radio Networks), C-RNTI (Cell-Temporary Identifier for Radio Networks), or a dedicated RNTI.

[0123] In some other implementations, the response from the base station is a bit field in DCI format 2_6. For example, the bit field carrying the response follows existing bit fields of DCI format 2_6 in version 17 (Rel-17), such as after a wake-up indication or after a SCell (Secondary Cell) sleep indication. Alternatively, the bit field carrying the response is an existing bit field of DCI format 2_6 in version 17. The meaning of this bit field is redefined. In some other implementations, the response from the base station is a bit field in DCI format 2_7. For example, the bit field carrying the response follows existing bit fields of DCI format 2_7 in version 17, such as after a paging indication or after a TRS availability indication. Alternatively, the bit field carrying the response is an existing bit field of DCI format 2_7 in version 17. The meaning of this bit field is redefined.

[0124] In some embodiments, the DCI format 2_6 or DCI format 2_7 with a response differs from the DCI format 2_6 or DCI format 2_7 in version 17. This difference includes at least one of the following: RNTI, flag bits, or bit fields in the DCI. For example, DCI format 2_6 with ps-RNTI is used for wake-up indication and / or SCell sleep indication for Rel-17 UEs, while DCI format 2_6 with a new RNTI is used to carry the response. As another example, flag bits or bit fields are added to DCI format 2_6. When the flag bit is bit "1", this indicates that DCI format 2_6 is used to carry the response; otherwise, DCI format 2_6 is used for wake-up indication and / or SCell sleep indication for Rel-17 UEs. Alternatively, DCI format 2_6 is used to carry the response when at least one bit field in DCI format 2_6 satisfies a preset condition (e.g., all 0s or all 1s); otherwise, DCI format 2_6 is used for wake-up indication and / or SCell sleep indication for Rel-17 UEs.

[0125] In some other embodiments, the DCI includes information related to at least one of the following: early paging indication, paging message scheduling information, system information scheduling information, and wake-up indication for the UE.

[0126] In some other implementations, the information is carried by a sequence, wherein the sequence is a PN (PseudoNoise) sequence, such as a CSI-RS (Channel State Information Reference Signal) based sequence or an SSS based sequence.

[0127] In some other implementations, this information is carried by higher-level signaling (such as MAC CE or RRC signaling).

[0128] In some embodiments, the information carried by the reference signal / data is determined by at least one of the following: a sequence generation scheme for sequence initialization; a format (e.g., DCI format); time-domain resource allocation; frequency-domain resource allocation, higher-level configuration, and / or scrambling method.

[0129] In some other embodiments, the functionality of the reference signal / data is distinguished by at least one of the following: a sequence generation scheme for sequence initialization, a format (e.g., DCI format), time-domain resource allocation, frequency-domain resource allocation, higher-level configuration, and / or scrambling method.

[0130] UE response to not receiving a response from the base station

[0131] Under predetermined conditions, the UE continuously transmits reference signals / data containing first information. In some implementations, the predetermined conditions include at least one of the following: the UE does not receive any information from the base station, the UE receives a NACK indication from the base station, and / or the base station's response differs from the UE's indication.

[0132] In some other implementations, the continuous transmission of reference signals or data by the UE includes one of the following operating modes.

[0133] The UE may continuously transmit data / reference signals if any single condition or any combination of two or more of the following conditions is met: (1) the timer expires; (2) the preset condition is met; and / or (3) the number of data / reference signal transmissions does not exceed the maximum number of transmissions. In some embodiments, the timer is started after the UE transmits data / reference signals;

[0134] For example, if the preset conditions are met, the UE can continuously transmit data / reference signals.

[0135] For example, when the preset conditions are met and the number of data / reference signal transmissions does not exceed the maximum number of transmissions, the UE can continuously transmit data / reference signals.

[0136] In some embodiments, the preset conditions include at least one of the following: the UE does not receive any indication from the base station; the UE receives a NACK indication from the base station; or the response from the base station is different from the UE's indication.

[0137] In some other implementations, a continuous reference signal or data is transmitted at increased power, and the increased power may be determined by at least one of the following: higher-layer parameters (e.g., the transmission power for each transmission timing is determined by higher-layer signaling); UE capabilities (e.g., UE capabilities include at least the capability of maximum transmission power or maximum number of MIMO layers / maximum number of antennas); number of transmissions (e.g., when the number of transmissions exceeds a threshold, the UE transmits the reference signal or channel at increased power); power used in previous transmissions; and an increment value (e.g., the transmission power in a continuous transmission is determined by adding or multiplying the power in previous transmissions by an increment value, and / or the increment value is determined by at least one of the following: higher-layer parameters or UE capabilities).

[0138] In some other implementations, the continuous reference signal or data is transmitted in a repetitive manner, and the number of repetitions can be determined by at least one of the following: higher-layer parameters (e.g., the number of repetitions per transmission opportunity is determined by higher-layer signaling); UE capabilities (e.g., UE capabilities include at least the maximum number of repetitions or the maximum number of MIMO layers / maximum number of antennas); the number of repetitions in previous transmissions; and an increment value (e.g., the number of repetitions in continuous transmissions is determined by adding or multiplying the number of repetitions in previous transmissions by an increment value, and / or the increment value is determined by at least one of the following: higher-layer parameters or UE capabilities).

[0139] In some other implementations, at least one of consecutive reference signals or data is transmitted within more than one time slot.

[0140] In some other implementations, the UE selects another cell under predetermined conditions, and the predetermined conditions include at least one of the following: the UE does not receive any indication from the base station; the UE receives a NACK indication from the base station; the base station's response differs from the UE's indication; and / or the number of transmissions of reference signals / data exceeds a maximum value.

[0141] In some other implementations, the successive transmissions of the reference signal or data may be different; and / or the information carried by the successive transmissions of the reference signal or data may be different.

[0142] Other information on the base station side

[0143] In various embodiments, the base station (e.g., gNB) can receive information carried by data and / or reference signals from the UE; and / or the gNB can perform a state (mode) transition operation according to at least one of the following.

[0144] The gNB can perform a state (mode) transition operation based on X indications received from the UE by the network to indicate a state (mode) transition, where X ≥ 1 or X / N ≥ p. N is the number of UEs in a cell, p ≤ 1, and / or X is the number of UEs in the same power consumption state.

[0145] The gNB can perform state (mode) transition operations based on the UE assistance information in this information. At least one of the UE assistance information satisfies at least one of the following conditions: the UE's mobility is below a threshold; the UE's current service is not sensitive to latency, that is, it can tolerate large latency; the amount of data the UE needs to transmit in the subsequent cycle is small; the UE expects to enter a low-power state (e.g., idle state, inactive state, sleep state, and DRX-OFF); and / or the UE can obtain data / reference signals from other cells.

[0146] The gNB can perform state (mode) transition operations based on the number of UEs (user devices) in a cell. In some embodiments, when the number of UEs in a cell is less than a threshold, the network will switch the UEs to other cells and perform a state (mode) transition operation.

[0147] The gNB can perform state (mode) transition operations based on cell coverage. In some embodiments, when a cell can cover an area of ​​other cells (multiple cells can cover the same area), one or more cells with a smaller coverage area can perform a state (mode) transition operation. In some embodiments, when multiple cells can cover the same area, one or more cells with fewer UEs can be switched to a power-saving state. In some embodiments, when multiple cells can cover the same area, the base station can determine to deactivate one or more cells with fewer UEs.

[0148] The gNB can perform state (mode) transition operations based on the UE's configuration. In some embodiments, when the UE associated with an element is in a power-saving state (e.g., idle / inactive state, sleep state), the element can switch to the power-saving state. In some embodiments, when the UE is configured for CA (Carrier Aggregation) / DC (Dual Connectivity) and the UE can obtain the necessary information from one of multiple cells, the element can switch to the power-saving state.

[0149] The gNB can perform state (mode) transition operations based on the type of service currently being transmitted. In some embodiments, whether an element can perform a state (mode) transition operation is related to the type of service currently being transmitted. For example, for services with low data transmission requirements and insensitive to latency, an element can be switched to a power-saving state (e.g., reducing antenna / bandwidth / MIMO layers).

[0150] gNB can perform state (mode) transition operations based on UE capabilities.

[0151] The gNB can perform state (mode) transition operations based on at least one of the configured period, timer, and duration. Elements periodically switch to a power-saving state.

[0152] gNB can perform a wake-up operation based on at least one of the following.

[0153] The gNB receives X indications from the UE to indicate gNB wake-up, where X ≥ 1 or X / N ≥ p. N is the number of UEs in a cell, p ≤ 1, and / or X is the number of UEs in the same power state.

[0154] The gNB can perform a wake-up operation based on the UE assistance information received by the gNB. At least one of the UE assistance information satisfies at least one of the following conditions: the UE's movement speed is greater than a threshold; the UE's current service is sensitive to latency, i.e., large latency may not be acceptable; the UE has a large amount of data to transmit in the subsequent period; and / or the UE may not be able to obtain data / reference signals from other cells.

[0155] The gNB can perform a wake-up operation based on the number of UEs (terminals) in a cell exceeding a threshold and / or the network switching the UE to another cell and waking up the current cell.

[0156] The gNB can perform a wake-up operation based on the type of service currently being transmitted. For example, for URLLC (ultra-reliable and low-latency communication) services, where latency requirements are very high and the gNB should transmit data as quickly as possible, the corresponding element should be woken up.

[0157] gNB can perform wake-up operations based on UE capabilities.

[0158] The gNB can be configured to instruct the gNB to wake up in order to perform a wake-up operation, based on at least one of a period, a timer, and a duration.

[0159] In some embodiments, the base station changes its power state after receiving a reference signal and / or data from the UE. In some embodiments, after the base station changes its power state based on a reference signal and / or channel from the UE, it does not change its power state again until it receives the reference signal and / or channel from the UE again. In some other embodiments, after the base station changes its power state based on a reference signal and / or channel from the UE, it changes its power state after a duration, or it changes its power state until a timer expires. In some other embodiments, after the duration ends or the timer expires, the base station switches to the previous power state. In some other embodiments, after the duration ends or the timer expires, the base station switches to a default power state. In some embodiments, the default power state is configured by higher-layer parameters.
