FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for adaptive configured communication for network energy saving operations.

DESCRIPTION OF RELATED ART

These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, or global level. New Radio (NR), which also may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency-division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

DETAILED DESCRIPTION

In some examples, a network node110may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a network node110or a network node subsystem serving this coverage area, depending on the context in which the term is used. A network node110may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs120with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs120with service subscription. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs120having association with the femto cell (for example, UEs120in a closed subscriber group (CSG)). A network node110for a macro cell may be referred to as a macro network node. A network node110for a pico cell may be referred to as a pico network node. A network node110for a femto cell may be referred to as a femto network node or an in-home network node. In the example shown inFIG.1, the network node110amay be a macro network node for a macro cell102a, the network node110bmay be a pico network node for a pico cell102b, and the network node110cmay be a femto network node for a femto cell102c. A network node may support one or multiple (for example, three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a network node110that is mobile (for example, a mobile network node).

The wireless network100may include one or more relay stations. A relay station is a network node that can receive a transmission of data from an upstream node (for example, a network node110or a UE120) and send a transmission of the data to a downstream node (for example, a UE120or a network node110). A relay station may be a UE120that can relay transmissions for other UEs120. In the example shown inFIG.1, the network node110d(for example, a relay network node) may communicate with the network node110a(for example, a macro network node) and the UE120din order to facilitate communication between the network node110aand the UE120d. A network node110that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, or a relay, among other examples.

The wireless network100may be a heterogeneous network that includes network nodes110of different types, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes110may have different transmit power levels, different coverage areas, or different impacts on interference in the wireless network100. For example, macro network nodes may have a high transmit power level (for example, 5 to 40 watts) whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (for example, 0.1 to 2 watts).

The UEs120may be dispersed throughout the wireless network100, and each UE120may be stationary or mobile. A UE120may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. A UE120may be a cellular phone (for example, a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (for example, a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (for example, a smart ring or a smart bracelet)), an entertainment device (for example, a music device, a video device, or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, or any other suitable device that is configured to communicate via a wireless or wired medium.

Some UEs120may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, or a location tag, that may communicate with a network node, another device (for example, a remote device), or some other entity. Some UEs120may be considered Internet-of-Things (IoT) devices, or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs120may be considered a Customer Premises Equipment. A UE120may be included inside a housing284that houses components of the UE120, such as processor components or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (for example, one or more processors) and the memory components (for example, a memory) may be operatively coupled, communicatively coupled, electronically coupled, or electrically coupled.

In general, any number of wireless networks100may be deployed in a given geographic area. Each wireless network100may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology or an air interface. A frequency may be referred to as a carrier or a frequency channel. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some examples, two or more UEs120(for example, shown as UE120aand UE120e) may communicate directly using one or more sidelink channels (for example, without using a network node110as an intermediary to communicate with one another). For example, the UEs120may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (for example, which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), or a mesh network. In such examples, a UE120may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by the network node110.

In some aspects, the UE120may include a communication manager140. As described in more detail elsewhere herein, the communication manager140may receive a configuration for SPS or a CG, the configuration indicating a first set of parameters, of the SPS or the CG, for a first state of a first TRP and a second set of parameters, of the SPS or the CG, for a second state of the first TRP, and the configuration including information indicating that the first set of parameters and the second set of parameters are for the first TRP; and communicate with the first TRP in accordance with the configuration. Additionally, or alternatively, the communication manager140may perform one or more other operations described herein.

In some aspects, the network node110may include a communication manager150. As described in more detail elsewhere herein, the communication manager150may output a configuration for SPS or a CG, the configuration indicating a first set of parameters, of the SPS or the CG, for a first state of a first TRP and a second set of parameters, of the SPS or the CG, for a second state of the first TRP, and the configuration including information indicating that the first set of parameters and the second set of parameters are for the first TRP; and communicate in accordance with the configuration. Additionally, or alternatively, the communication manager150may perform one or more other operations described herein.

At the network node110, a transmit processor220may receive data, from a data source212, intended for the UE120(or a set of UEs120). The transmit processor220may select one or more modulation and coding schemes (MCSs) for the UE120using one or more channel quality indicators (CQIs) received from that UE120. The network node110may process (for example, encode and modulate) the data for the UE120using the MCS(s) selected for the UE120and may provide data symbols for the UE120. The transmit processor220may process system information (for example, for semi-static resource partitioning information (SRPI)) and control information (for example, CQI requests, grants, or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor220may generate reference symbols for reference signals (for example, a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (for example, a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor230may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, T output symbol streams) to a corresponding set of modems232(for example, T modems), shown as modems232athrough232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem232. Each modem232may use a respective modulator component to process a respective output symbol stream (for example, for OFDM) to obtain an output sample stream. Each modem232may further use a respective modulator component to process (for example, convert to analog, amplify, filter, or upconvert) the output sample stream to obtain a downlink signal. The modems232athrough232tmay transmit a set of downlink signals (for example, T downlink signals) via a corresponding set of antennas234(for example, T antennas), shown as antennas234athrough234t.

At the UE120, a set of antennas252(shown as antennas252athrough252r) may receive the downlink signals from the network node110or other network nodes110and may provide a set of received signals (for example, R received signals) to a set of modems254(for example, R modems), shown as modems254athrough254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem254. Each modem254may use a respective demodulator component to condition (for example, filter, amplify, downconvert, or digitize) a received signal to obtain input samples. Each modem254may use a demodulator component to further process the input samples (for example, for OFDM) to obtain received symbols. A MIMO detector256may obtain received symbols from the modems254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor258may process (for example, demodulate and decode) the detected symbols, may provide decoded data for the UE120to a data sink260, and may provide decoded control information and system information to a controller/processor280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, or a CQI parameter, among other examples. In some examples, one or more components of the UE120may be included in a housing.

One or more antennas (for example, antennas234athrough234tor antennas252athrough252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or one or more antenna elements coupled to one or more transmission or reception components, such as one or more components ofFIG.2.

On the uplink, at the UE120, a transmit processor264may receive and process data from a data source262and control information (for example, for reports that include RSRP, RSSI, RSRQ, or CQI) from the controller/processor280. The transmit processor264may generate reference symbols for one or more reference signals. The symbols from the transmit processor264may be precoded by a TX MIMO processor266if applicable, further processed by the modems254(for example, for DFT-s-OFDM or CP-OFDM), and transmitted to the network node110. In some examples, the modem254of the UE120may include a modulator and a demodulator. In some examples, the UE120includes a transceiver. The transceiver may include any combination of the antenna(s)252, the modem(s)254, the MIMO detector256, the receive processor258, the transmit processor264, or the TX MIMO processor266. The transceiver may be used by a processor (for example, the controller/processor280) and the memory282to perform aspects of any of the processes described herein (e.g., with reference toFIGS.4-13).

In some aspects, the controller/processor280may be a component of a processing system. A processing system may generally be a system or a series of machines or components that receives inputs and processes the inputs to produce a set of outputs (which may be passed to other systems or components of, for example, the UE120). For example, a processing system of the UE120may be a system that includes the various other components or subcomponents of the UE120.

The processing system of the UE120may interface with one or more other components of the UE120, may process information received from one or more other components (such as inputs or signals), or may output information to one or more other components. For example, a chip or modem of the UE120may include a processing system, a first interface to receive or obtain information, and a second interface to output, transmit, or provide information. In some examples, the first interface may be an interface between the processing system of the chip or modem and a receiver, such that the UE120may receive information or signal inputs, and the information may be passed to the processing system. In some examples, the second interface may be an interface between the processing system of the chip or modem and a transmitter, such that the UE120may transmit information output from the chip or modem. A person having ordinary skill in the art will readily recognize that the second interface also may obtain or receive information or signal inputs, and the first interface also may output, transmit, or provide information.

In some aspects, the controller/processor240may be a component of a processing system. A processing system may generally be a system or a series of machines or components that receives inputs and processes the inputs to produce a set of outputs (which may be passed to other systems or components of, for example, the network node110). For example, a processing system of the network node110may be a system that includes the various other components or subcomponents of the network node110.

The processing system of the network node110may interface with one or more other components of the network node110, may process information received from one or more other components (such as inputs or signals), or may output information to one or more other components. For example, a chip or modem of the network node110may include a processing system, a first interface to receive or obtain information, and a second interface to output, transmit, or provide information. In some examples, the first interface may be an interface between the processing system of the chip or modem and a receiver, such that the network node110may receive information or signal inputs, and the information may be passed to the processing system. In some examples, the second interface may be an interface between the processing system of the chip or modem and a transmitter, such that the network node110may transmit information output from the chip or modem. A person having ordinary skill in the art will readily recognize that the second interface also may obtain or receive information or signal inputs, and the first interface also may output, transmit, or provide information.

The controller/processor240of the network node110, the controller/processor280of the UE120, or any other component(s) ofFIG.2may perform one or more techniques associated with network energy savings, as described in more detail elsewhere herein. For example, the controller/processor240of the network node110, the controller/processor280of the UE120, or any other component(s) (or combinations of components) ofFIG.2may perform or direct operations of, for example, process1000ofFIG.10, process1100ofFIG.11, and/or other processes as described herein. The memory242and the memory282may store data and program codes for the network node110and the UE120, respectively. In some examples, the memory242and the memory282may include a non-transitory computer-readable medium storing one or more instructions (for example, code or program code) for wireless communication. For example, the one or more instructions, when executed (for example, directly, or after compiling, converting, or interpreting) by one or more processors of the network node110or the UE120, may cause the one or more processors, the UE120, or the network node110to perform or direct operations of, for example, process1000ofFIG.10, process1100ofFIG.11, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

In some aspects, a UE (e.g., UE120) includes means for receiving a configuration for SPS or a CG, the configuration indicating a first set of parameters, of the SPS or the CG, for a first state of a first TRP and a second set of parameters, of the SPS or the CG, for a second state of the first TRP, and the configuration including information indicating that the first set of parameters and the second set of parameters are for the first TRP; and/or means for communicating with the first TRP in accordance with the configuration. The means for the UE to perform operations described herein may include, for example, one or more of communication manager140, antenna252, modem254, MIMO detector256, receive processor258, transmit processor264, TX MIMO processor266, controller/processor280, or memory282.

In some aspects, a network node (e.g., network node110) includes means for outputting a configuration for SPS or a CG, the configuration indicating a first set of parameters, of the SPS or the CG, for a first state of a first TRP and a second set of parameters, of the SPS or the CG, for a second state of the first TRP, and the configuration including information indicating that the first set of parameters and the second set of parameters are for the first TRP; and/or means for communicating in accordance with the configuration. The means for the network node to perform operations described herein may include, for example, one or more of communication manager150, transmit processor220, TX MIMO processor230, modem232, antenna234, MIMO detector236, receive processor238, controller/processor240, memory242, or scheduler246.

FIG.4illustrates an example logical architecture of a distributed RAN400, in accordance with the present disclosure.

A 5G access node405may include an access node controller410. The access node controller410may be a central unit (CU) of the distributed RAN400. In some aspects, a backhaul interface to a 5G core network415may terminate at the access node controller410. The 5G core network415may include a 5G control plane component420and a 5G user plane component425(e.g., a 5G gateway), and the backhaul interface for one or both of the 5G control plane and the 5G user plane may terminate at the access node controller410. Additionally, or alternatively, a backhaul interface to one or more neighbor access nodes430(e.g., another 5G access node405and/or an LTE access node) may terminate at the access node controller410.

The access node controller410may include and/or may communicate with one or more TRPs435(e.g., via an F1 Control (F1-C) interface and/or an F1 User (F1-U) interface). A TRP435may include a distributed unit (DU) and/or a radio unit (RU) of the distributed RAN400. In some aspects, a TRP435may correspond to a network node110described above in connection withFIG.1. For example, different TRPs435may be included in different network nodes110. Additionally, or alternatively, multiple TRPs435may be included in a single network node110. In some aspects, a network node110may include a CU (e.g., access node controller410) and/or one or more DUs (e.g., one or more TRPs435). In some cases, a TRP435may be referred to as a cell, a panel, an antenna array, or an array.

A TRP435may be connected to a single access node controller410or to multiple access node controllers410. In some aspects, a dynamic configuration of split logical functions may be present within the architecture of distributed RAN400, referred to elsewhere herein as a functional split. For example, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and/or a medium access control (MAC) layer may be configured to terminate at the access node controller410or at a TRP435.

In some aspects, multiple TRPs435may transmit communications (e.g., the same communication or different communications) in the same transmission time interval (TTI) (e.g., a slot, a mini-slot, a subframe, or a symbol) or different TTIs using different quasi co-location (QCL) relationships (e.g., different spatial parameters, different transmission configuration indicator (TCI) states, different precoding parameters, and/or different beamforming parameters). In some aspects, a TCI state may be used to indicate one or more QCL relationships. A TRP435may be configured to individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs435) serve traffic to a UE120.

As indicated above,FIG.4is provided as an example. Other examples may differ from what was described with regard toFIG.4.

FIG.5is a diagram illustrating an example500of multi-TRP communication (sometimes referred to as multi-panel communication), in accordance with the present disclosure. As shown inFIG.5, multiple TRPs505may communicate with the same UE120. A TRP505may correspond to a TRP435described above in connection withFIG.4.

The multiple TRPs505(shown as TRP A and TRP B) may communicate with the same UE120in a coordinated manner (e.g., using coordinated multipoint transmissions) to improve reliability and/or increase throughput. The TRPs505may coordinate such communications via an interface between the TRPs505(e.g., a backhaul interface and/or an access node controller410). The interface may have a smaller delay and/or higher capacity when the TRPs505are co-located at the same network node110(e.g., when the TRPs505are different antenna arrays or panels of the same network node110), and may have a larger delay and/or lower capacity (as compared to co-location) when the TRPs505are located at different network nodes110. The different TRPs505may communicate with the UE120using different QCL relationships (e.g., different TCI states), different demodulation reference signal (DMRS) ports, and/or different layers (e.g., of a multi-layer communication).

In a first multi-TRP transmission mode (e.g., Mode 1), a single physical downlink control channel (PDCCH) may be used to schedule downlink data communications for a single physical downlink shared channel (PDSCH). In this case, multiple TRPs505(e.g., TRP A and TRP B) may transmit communications to the UE120on the same PDSCH. For example, a communication may be transmitted using a single codeword with different spatial layers for different TRPs505(e.g., where one codeword maps to a first set of layers transmitted by a first TRP505and maps to a second set of layers transmitted by a second TRP505). As another example, a communication may be transmitted using multiple codewords, where different codewords are transmitted by different TRPs505(e.g., using different sets of layers). In either case, different TRPs505may use different QCL relationships (e.g., different TCI states) for different DMRS ports corresponding to different layers. For example, a first TRP505may use a first QCL relationship or a first TCI state for a first set of DMRS ports corresponding to a first set of layers, and a second TRP505may use a second (different) QCL relationship or a second (different) TCI state for a second (different) set of DMRS ports corresponding to a second (different) set of layers. In some aspects, a TCI state in downlink control information (DCI) (e.g., transmitted on the PDCCH, such as DCI format 1_0 or DCI format 1_1) may indicate the first QCL relationship (e.g., by indicating a first TCI state) and the second QCL relationship (e.g., by indicating a second TCI state). The first and the second TCI states may be indicated using a TCI field in the DCI. In general, the TCI field can indicate a single TCI state (for single-TRP transmission) or multiple TCI states (for multi-TRP transmission as discussed here) in this multi-TRP transmission mode (e.g., Mode 1).

In a second multi-TRP transmission mode (e.g., Mode 2), multiple PDCCHs may be used to schedule downlink data communications for multiple corresponding PDSCHs (e.g., one PDCCH for each PDSCH). In this case, a first PDCCH may schedule a first codeword to be transmitted by a first TRP505, and a second PDCCH may schedule a second codeword to be transmitted by a second TRP505. Furthermore, first DCI (e.g., transmitted by the first TRP505) may schedule a first PDSCH communication associated with a first set of DMRS ports with a first QCL relationship (e.g., indicated by a first TCI state) for the first TRP505, and second DCI (e.g., transmitted by the second TRP505) may schedule a second PDSCH communication associated with a second set of DMRS ports with a second QCL relationship (e.g., indicated by a second TCI state) for the second TRP505. In this case, DCI (e.g., having DCI format 1_0 or DCI format 1_1) may indicate a corresponding TCI state for a TRP505corresponding to the DCI. The TCI field of a DCI indicates the corresponding TCI state (e.g., the TCI field of the first DCI indicates the first TCI state and the TCI field of the second DCI indicates the second TCI state).

FIG.6is a diagram illustrating an example of TRP differentiation at a UE based at least in part on a CORESET pool index, in accordance with the present disclosure. In some aspects, a CORESET pool index (or CORESETPoolIndex) value may be used by a UE (a UE120) to identify a TRP associated with an uplink grant received on a PDCCH.

A CORESET may refer to a control region that is structured to support an efficient use of resources, such as by flexible configuration or reconfiguration of resources for one or more PDCCHs associated with a UE. In some aspects, a CORESET may occupy the first symbol of an orthogonal frequency division multiplexing (OFDM) slot, the first two symbols of an OFDM slot, or the first three symbols of an OFDM slot. Thus, a CORESET may include multiple resource blocks (RBs) in the frequency domain, and either one, two, or three symbols in the time domain. In 5G, a quantity of resources included in a CORESET may be flexibly configured, such as by using radio resource control (RRC) signaling to indicate a frequency domain region (for example, a quantity of resource blocks) or a time domain region (for example, a quantity of symbols) for the CORESET.

As illustrated inFIG.6, a UE120may be configured with multiple CORESETs in a given serving cell. Each CORESET configured for the UE120may be associated with a CORESET identifier (CORESET ID). For example, a first CORESET configured for the UE120may be associated with CORESET ID1, a second CORESET configured for the UE120may be associated with CORESET ID2, a third CORESET configured for the UE120may be associated with CORESET ID3, and a fourth CORESET configured for the UE120may be associated with CORESET ID4.

As further illustrated inFIG.6, two or more (for example, up to five) CORESETs may be grouped into a CORESET pool. Each CORESET pool may be associated with a CORESET pool index. As an example, CORESET ID1and CORESET ID2may be grouped into CORESET pool index0, and CORESET ID3and CORESET ID4may be grouped into CORESET pool index1. In a multi-TRP configuration, each CORESET pool index value may be associated with a particular TRP605. As an example, and as illustrated inFIG.6, a first TRP605(TRP A) (or a first network node100) may be associated with CORESET pool index0and a second TRP605(TRP B) (or a second network node110) may be associated with CORESET pool index1. The UE120may be configured by a higher layer parameter, such as PDCCH-Config, with information identifying an association between a TRP and a CORESET pool index value assigned to the TRP. Accordingly, the UE may identify the TRP that transmitted a DCI uplink grant by determining the CORESET ID of the CORESET in which the PDCCH carrying the DCI uplink grant was transmitted, determining the CORESET pool index value associated with the CORESET pool in which the CORESET ID is included, and identifying the TRP associated with the CORESET pool index value.

FIG.7is a diagram illustrating an example700of downlink semi-persistent scheduling (SPS) communication and an example710of uplink configured grant (CG) communication, in accordance with the present disclosure. SPS communications may include periodic downlink communications that are configured for a UE, such that a network node does not need to transmit (e.g., directly or via one or more network nodes) separate DCI to schedule each downlink communication, thereby conserving signaling overhead. CG communications may include periodic uplink communications that are configured for a UE, such that the network node does not need to transmit (e.g., directly or via one or more network nodes) separate DCI to schedule each uplink communication, thereby conserving signaling overhead.

As shown in example700, a UE may be configured with an SPS configuration for SPS communications. For example, the UE may receive the SPS configuration via a radio resource control (RRC) message transmitted by a network node (e.g., directly to the UE or via one or more network nodes). The SPS configuration may indicate a resource allocation associated with SPS downlink communications (e.g., in a time domain, frequency domain, spatial domain, and/or code domain) and a periodicity at which the resource allocation is repeated, resulting in periodically reoccurring scheduled SPS occasions705for the UE. The SPS configuration may also configure hybrid automatic repeat request (HARD) acknowledgement (ACK) (HARQ-ACK) feedback resources for the UE to transmit HARQ-ACK feedback for SPS PDSCH communications received in the SPS occasions705. For example, the SPS configuration may indicate a PDSCH-to-HARQ feedback timing value, which may be referred to as a K1 value in a wireless communication specification (e.g., a 3GPP specification).

The network node may transmit SPS activation DCI to the UE (e.g., directly or via one or more network nodes) to activate the SPS configuration for the UE. The network node may indicate, in the SPS activation DCI, communication parameters, such as an MCS, a resource block (RB) allocation, and/or antenna ports, for the SPS PDSCH communications to be transmitted in the scheduled SPS occasions705. The UE may begin monitoring the SPS occasions705based at least in part on receiving the SPS activation DCI. For example, beginning with a next scheduled SPS occasion705subsequent to receiving the SPS activation DCI, the UE may monitor the scheduled SPS occasions705to decode PDSCH communications using the communication parameters indicated in the SPS activation DCI. The UE may refrain from monitoring configured SPS occasions705prior to receiving the SPS activation DCI.

The network node may transmit SPS reactivation DCI to the UE (e.g., directly or via one or more network nodes) to change the communication parameters for the SPS PDSCH communications. Based at least in part on receiving the SPS reactivation DCI, the UE may begin monitoring the scheduled SPS occasions705using the communication parameters indicated in the SPS reactivation DCI. For example, beginning with a next scheduled SPS occasion705subsequent to receiving the SPS reactivation DCI, the UE may monitor the scheduled SPS occasions705to decode PDSCH communications based on the communication parameters indicated in the SPS reactivation DCI.

In some cases, such as when there is not downlink traffic to transmit to the UE, the network node may transmit SPS cancellation DCI to the UE (e.g., directly or via one or more network nodes) to temporarily cancel or deactivate one or more subsequent SPS occasions705for the UE. The SPS cancellation DCI may deactivate only a subsequent single SPS occasion705or a subsequent N SPS occasions705(where N is an integer). SPS occasions705after the one or more (e.g., N) SPS occasions705subsequent to the SPS cancellation DCI may remain activated. Based at least in part on receiving the SPS cancellation DCI, the UE may refrain from monitoring the one or more (e.g., N) SPS occasions705subsequent to receiving the SPS cancellation DCI. As shown in example700, the SPS cancellation DCI cancels one subsequent SPS occasion705for the UE. After the SPS occasion705(or N SPS occasions) subsequent to receiving the SPS cancellation DCI, the UE may automatically resume monitoring the scheduled SPS occasions705.

The network node may transmit SPS release DCI to the UE (e.g., directly or via one or more network nodes) to deactivate the SPS configuration for the UE. The UE may stop monitoring the scheduled SPS occasions705based at least in part on receiving the SPS release DCI. For example, the UE may refrain from monitoring any scheduled SPS occasions705until another SPS activation DCI is received by the UE. Whereas the SPS cancellation DCI may deactivate only a subsequent single SPS occasion705or a subsequent N SPS occasions705, the SPS release DCI deactivates all subsequent SPS occasions705for a given SPS configuration for the UE until the given SPS configuration is activated again by a new SPS activation DCI.

As shown in example710, a UE may be configured with a CG configuration for CG communications. For example, the UE may receive the CG configuration via an RRC message transmitted by a network node (e.g., directly to the UE or via one or more network nodes). The CG configuration may indicate a resource allocation associated with CG uplink communications (e.g., in a time domain, frequency domain, spatial domain, and/or code domain) and a periodicity at which the resource allocation is repeated, resulting in periodically reoccurring scheduled CG occasions715for the UE. In some examples, the CG configuration may identify a resource pool or multiple resource pools that are available to the UE for an uplink transmission. The CG configuration may configure contention-free CG communications (e.g., where resources are dedicated for the UE to transmit uplink communications) or contention-based CG communications (e.g., where the UE contends for access to a channel in the configured resource allocation, such as by using a channel access procedure or a channel sensing procedure).

The network node may transmit CG activation DCI to the UE (e.g., directly or via one or more network nodes) to activate the CG configuration for the UE. The network node may indicate, in the CG activation DCI, communication parameters, such as an MCS, an RB allocation, and/or antenna ports, for the CG physical uplink shared channel (PUSCH) communications to be transmitted in the scheduled CG occasions715. The UE may begin transmitting in the CG occasions715based at least in part on receiving the CG activation DCI. For example, beginning with a next scheduled CG occasion715subsequent to receiving the CG activation DCI, the UE may transmit a PUSCH communication in the scheduled CG occasions715using the communication parameters indicated in the CG activation DCI. The UE may refrain from transmitting in configured CG occasions715prior to receiving the CG activation DCI.

The network node may transmit CG reactivation DCI to the UE (e.g., directly or via one or more network nodes) to change the communication parameters for the CG PUSCH communications. Based at least in part on receiving the CG reactivation DCI, the UE may begin transmitting in the scheduled CG occasions715using the communication parameters indicated in the CG reactivation DCI. For example, beginning with a next scheduled CG occasion715subsequent to receiving the CG reactivation DCI, the UE may transmit PUSCH communications in the scheduled CG occasions715based at least in part on the communication parameters indicated in the CG reactivation DCI.

In some cases, such as when the network node needs to override a scheduled CG communication for a higher priority communication, the network node may transmit CG cancellation DCI to the UE (e.g., directly or via one or more network nodes) to temporarily cancel or deactivate one or more subsequent CG occasions715for the UE. The CG cancellation DCI may deactivate only a subsequent single CG occasion715or a subsequent N CG occasions715(where N is an integer). CG occasions715after the one or more (e.g., N) CG occasions715subsequent to the CG cancellation DCI may remain activated. Based at least in part on receiving the CG cancellation DCI, the UE may refrain from transmitting in the one or more (e.g., N) CG occasions715subsequent to receiving the CG cancellation DCI. As shown in example710, the CG cancellation DCI cancels one subsequent CG occasion715for the UE. After the CG occasion715(or N CG occasions) subsequent to receiving the CG cancellation DCI, the UE may automatically resume transmission in the scheduled CG occasions715.

The network node may transmit CG release DCI to the UE (e.g., directly or via one or more network nodes) to deactivate the CG configuration for the UE. The UE may stop transmitting in the scheduled CG occasions715based at least in part on receiving the CG release DCI. For example, the UE may refrain from transmitting in any scheduled CG occasions715until another CG activation DCI is received by the UE. Whereas the CG cancellation DCI may deactivate only a subsequent single CG occasion715or a subsequent N CG occasions715, the CG release DCI deactivates all subsequent CG occasions715for a given CG configuration for the UE until the given CG configuration is activated again by a new CG activation DCI.

FIG.8is a diagram illustrating an example800of network operations to reduce energy consumption in accordance with the present disclosure. Network energy saving and/or network energy efficiency measures are expected to have increased importance in wireless network operations for various reasons, including climate change mitigation, environmental sustainability, and network cost reduction. For example, although NR generally offers a significant energy efficiency improvement per gigabyte over previous generations (for example, LTE), new NR use cases that demand high data rates and/or the adoption of millimeter wave frequencies may require more network sites, greater network density, more network antennas, larger bandwidths, and/or more frequency bands, which could potentially lead to a more efficient wireless network that nonetheless has higher energy requirements and/or causes more emissions than previous wireless network generations. Furthermore, energy accounts for a significant proportion of the cost to operate a wireless network. For example, according to some estimates, energy costs are about one-fourth the total cost to operate a wireless network, and over 90% of network operating costs are spent on energy (for example, fuel and electricity). Most energy consumption and/or energy costs come from powering a RAN, which accounts for about half of the energy consumed by a wireless network. Accordingly, measures to increase network energy savings and/or network energy efficiency are important factors that may drive adoption and/or expansion of wireless networks.

One way to increase energy efficiency in a RAN may be to adapt network energy consumption models to achieve more efficient operation dynamically and/or semi-statically. For example, power consumption in a RAN can generally be split into a dynamic portion, in which power is consumed only when data transmission and/or reception is ongoing, and a static portion, in which power is consumed all of the time to maintain the operation of radio access devices even when data transmission and/or reception is not ongoing. Accordingly, one potential approach to improve network energy savings may be to adapt power consumption models from the network perspective by reducing relative energy consumption for downlink and/or uplink communication (for example, considering factors such as power amplifier (PA) efficiency, quantities of transceiver units (TxRUs), and/or network load, among other examples), enabling network sleep states and associated transition times, and/or defining appropriate reference parameters and/or configurations. For example, in some cases, different network energy savings (NES) states may be configured to enable granular adaptation of transmission and/or reception to reduce energy consumption using techniques in time, frequency, spatial, and/or power domains, with potential support and/or feedback from UEs and/or potential UE assistance information. However, network devices and UE may need to exchange and/or coordinate information over network interfaces, such as control configurations, communication parameters, and/or UE behavior for each NES state, which can increase configuration complexity and/or signaling overhead. This may pose challenges because techniques to reduce network energy consumption should generally be designed to avoid having a large impact on key performance indicators (KPIs) related to network and/or UE performance (for example, spectral efficiency, latency, UE power consumption, and/or complexity, among other examples).

Accordingly, as shown inFIG.8, a network node may be configured to operate in different NES states810over time, where each NES state810may use one or more techniques to adapt transmission and/or reception in time, frequency, spatial, and/or power domains. For example, as shown inFIG.8, the NES states810may include a normal operation mode (which may also be referred to as a legacy mode or a default mode) and one or more sleep modes that may be associated with a lower power consumption than the normal operation mode. In general, a network node may transition between different NES states810to save power and maintain network operation (for example, minimizing impact on KPIs such as spectral efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and/or service level agreement (SLA) assurance). Furthermore, the network node may transition between different sleep modes based on traffic demands (for example, entering a light sleep mode when traffic demands are slightly lower than usual and/or entering a deep sleep mode when traffic demands are much lower than usual), and different sleep modes may be associated with different energy saving techniques (for example, one or more antenna panels, antenna ports, and/or radio frequency (RF) chains may be turned off in the deep sleep mode but remain on in the light sleep mode). Accordingly, as shown inFIG.8, the normal operation mode and the different sleep modes may vary in terms of power consumption and may be associated with different transition times (for example, a transition time to or from the deep sleep mode may be longer than a transition time to or from the light sleep mode).

In some cases, as described herein, an NES state810may generally correspond to a particular set of configurations, communication parameters, and/or UE behaviors. For example, an NES state810may include a set of configurations, communication parameters, and/or UE behaviors associated with one or more energy saving techniques that are implemented in the time, frequency, spatial, and/or power domain to reduce energy consumption. For example, a network node may be configured to not transmit a synchronization signal block (SSB) to reduce energy consumption in a first NES state810(for example, an SSB-less NES state810), and may be configured to employ other energy saving techniques such as turning off one or more antenna panels in a second NES state810. Furthermore, in some cases, an NES state810may be associated with a set of configurations, communication parameters, and/or UE behaviors associated with the normal or legacy mode of network operation. Accordingly, because one design objective in energy-efficient wireless networks is to achieve more efficient operation dynamically and/or semi-statically, a network node may configure a semi-static pattern820to achieve network energy savings. For example, as shown inFIG.8, the semi-static pattern820(for example, configured via RRC signaling) may include a sequence of NES states810that the network node follows in accordance with a given periodicity (for example, inFIG.8, the network node operates in accordance with a first NES state, shown as NES1, for a first time period, then operates in a flexible mode for a second time period, then operates in accordance with a second NES state, shown as NES2, for a third time period, and the pattern then repeats). In cases where the semi-static pattern820includes a flexible mode, the network node may operate in accordance with any suitable NES state during the time period corresponding to the flexible mode (for example, depending on current traffic conditions), and the NES state that the network node selects for the time period corresponding to the flexible mode may be dynamically indicated to served UEs. In some examples, a UE may be configured with an SPS configuration (referred to herein as a configuration for SPS) or a CG configuration (referred to herein as a configuration for a CG). As used herein, “a configuration for SPS or a CG” can refer to an SPS configuration (or part of an SPS configuration), a CG configuration (or part of a CG configuration), or a combination thereof. In some examples, a configuration for SPS or a CG may be configured for joint transmissions to or from multiple TRPs, which may improve reliability such as for critical traffic. For example, the configuration may indicate information related to decoding or transmitting data for multiple TRPs, such as a time-domain resource allocation (TDRA), a frequency-domain resource allocation (FDRA), a CORESET pool index, a TCI state, or the like. However, in some scenarios, a TRP of the multiple TRPs may dynamically change an NES state810(e.g., the TRP may enter or leave a deep sleep). In this situation, the TRP may not be permitted to transmit in the deep sleep. If the UE is currently communicating in accordance with the configuration (e.g., by transmitting on activated CG occasions or receiving on activated SPS occasions) without taking into account the changed NES state810, errors may occur. However, explicitly reconfiguring the configuration (such as by deactivating or releasing a current configuration for SPS or the CG and configuring another configuration for SPS or CG), may incur delay and signaling overhead.

Some techniques described herein provide configuration of an adaptive SPS or CG, such as to support dynamic network energy saving operations. For example, a UE may be configured with a configuration for SPS or CG. The configuration may include a first set of parameters (e.g., a first set of SPS parameters or a first set of CG parameters) for a first state (e.g., a first NES state) of a TRP and a second set of parameters (e.g., a second set of SPS parameters or a second set of CG parameters) for a second state (e.g., a second NES state) of the TRP. The UE may communicate with the TRP based on the configuration. For example, the UE may use the first set of parameters while the TRP is in the first state. As another example, the UE may use the second set of parameters while the TRP is in the second state. Providing different sets of parameters (e.g., SPS parameters or CG parameters) for different states of the network node may conserve signaling overhead and reduce delay relative to explicitly reconfiguring an SPS configuration or CG configuration each time the state of the network node changes.

FIG.9is a diagram illustrating an example900of signaling associated with adaptive configured communication for network energy saving operations, in accordance with the present disclosure. Example900includes a UE (e.g., UE120) and a network node (e.g., network node110, CU310, DU330). As shown, the network node is associated with a first TRP and a second TRP (e.g., network node110, DU330, RU340, TRP605, TRP505, TRP435). In some aspects, the network node may output a communication. For example, the network node may transmit the communication (e.g., directly) or may provide the communication for transmission by a TRP (e.g., the first TRP or the second TRP). In some aspects, the network node may obtain a communication. For example, the network node may receive the communication (e.g., directly) or may receive the communication from a TRP (e.g., the first TRP or the second TRP).

As shown by reference number910, the network node may output, and the UE may receive, configuration information. For example, the UE may receive the configuration information via RRC signaling (e.g., one or more RRC messages), medium access control (MAC) signaling (e.g., one or more MAC messages), downlink control information (DCI) (e.g., one or more DCI messages), or a combination thereof.

In some aspects, the configuration information may include a configuration for SPS, such as one or more of the parameters of an SPS configuration described with regard toFIG.7. Additionally, or alternatively, the configuration information may include a configuration for a CG, such as one or more of the parameters of a CG configuration described with regard toFIG.7. For example, the configuration information may include an SPS configuration, a subset of an SPS configuration, multiple SPS configurations, or a combination thereof. In some aspects, the SPS configuration may indicate that the SPS configuration is associated with the network node (e.g., the first TRP and/or the second TRP). For example, the configuration information may include a CG configuration, a subset of a CG configuration, multiple CG configurations, or a combination thereof. In some aspects, the CG configuration may indicate that the CG configuration is associated with the network node (e.g., the first TRP and/or the second TRP).

In some aspects, the configuration information may include a configuration associated with a state of one or more TRPs. For example, the configuration information may indicate a semi-static pattern (e.g., semi-static pattern820) for one or more NES states of a TRP. As another example, the configuration information may indicate a first semi-static pattern for one or more NES states of a first TRP and a second semi-static pattern for one or more NES states of a second TRP. As yet another example, the configuration information may indicate a first semi-static pattern for first NES states and second NES states of a first TRP and a second semi-static pattern for first NES states and second NES states of a second TRP. As yet another example, the configuration information may indicate a semi-static pattern that indicates states of multiple TRPs (e.g., a single semi-static pattern may indicate a combined state of the first TRP and the second TRP, such as “first TRP=NES1and second TRP=NES2” at a given time).

The configuration information may include a configuration indicating a first set of parameters associated with a first state of the first TRP and a second set of parameters associated with a second state of the first TRP. For example, the configuration may be part of the RRC configuration of the SPS or the CG. In some aspects, the first set of parameters and the second set of parameters may include a parameter configurable as part of an SPS configuration, a CG configuration, or an activation of an SPS configuration or a CG configuration. In some aspects, a parameter, of the first set of parameters or the second set of parameters, may include a modulation and coding scheme (MCS) value, a delta MCS (indicating a change of MCS from a baseline or default value), a rank indicator, a power control value, a combination thereof, or another parameter associated with transmission or reception on SPS or CG configurations. In some aspects, the second set of parameters may be configured using an offset relative to the first set of parameters. In some aspects, the second set of parameters and the first set of parameters may each be configured as respective sets of explicit values. In some aspects, the configuration of the first set of parameters and/or the second set of parameters may indicate a TRP with which the configuration (e.g., the first set of parameters and/or the second set of parameters) is associated. For example, the configuration may indicate a TCI state and a CORESET pool index of a TRP with which the first set of parameters and/or the second set of parameters are associated. In some aspects, the first set of parameters or the second set of parameters may indicate whether or not to transmit or receive at a given time (e.g., whether to skip a CG or SPS occasion due to, for example, the corresponding TRP being in a deep sleep state). Thus, the first set of parameters or the second set of parameters may be said to be “for the CG or the SPS” in that the first set of parameters or the second set of parameters indicate one or more parameters for transmitting or receiving SPS or CG communications, and/or indicate whether to utilize an SPS occasion or a CG occasion.

In some aspects, the configuration may indicate multiple sets of parameters per TRP, of the first TRP and the second TRP. For example, the configuration may indicate a first set of parameters and a second set of parameters for a first TRP, and a third set of parameters for a first state and a second set of parameters for a second state for a second TRP. Thus, the UE can dynamically apply one or more sets of parameters according to a current state of the first TRP and the second TRP without being explicitly reconfigured at each state change of either of the first TRP or the second TRP. In some aspects, the configuration of the set(s) of parameters may indicate multiple sets of parameters, where each set of parameters of the multiple sets of parameters is associated with a respective combined state of the first TRP and the second TRP. A combined state of the first TRP and the second TRP at a given time collectively identifies a state of the first TRP and a state of the second TRP at the given time. For example, a configuration of a set of parameters may indicate, for one or more potential combined states of the first TRP and the second TRP, a transmission mode for the UE, as illustrated in Table 1, below. In Table 1, NES1 is a first NES state and NES2 is a second NES state, where in NES2, the corresponding TRP is in a deep sleep with no transmission allowed:

As shown in Table 1, when both TRPs are active (i.e., not in the NES2 state), the UE transmits or receives in multi-TRP (M-TRP) mode (such as using TCI states associated with both TRPs). When only one TRP is active (i.e., only one TRP is not in the NES2 state), the UE transmits or receives in a single TRP mode corresponding to the active TRP (such as using a TCI state associated with the active TRP). When both TRPs are in deep sleep, the UE skips a CG or SPS occasion occurring while both TRPs are in deep sleep.

As shown by reference number920, in some aspects, the network node may output, and the UE may receive, an indication of a state of a TRP. For example, the indication may indicate that a state of a TRP (e.g., a TRP that transmitted the indication or another TRP) is to change from a first state to a second state or from a second state to a first state. In some aspects, the UE may not receive such an indication. For example, the network node may provide one or more semi-static patterns that indicate states of the first TRP and the second TRP.

As shown by reference number930, in some aspects, the network node may output, and the UE may receive, signaling activating the configuration for SPS or the configuration for CG. The signaling may include, for example, RRC signaling, MAC signaling, or DCI. This is described above in more detail in connection withFIG.7.

As shown by reference number940, the UE may communicate with the network node (e.g., the first TRP, the second TRP, or a combination thereof) in accordance with the configuration for SPS or CG. For example, the UE may communicate with the first TRP using a set of parameters, of the configuration, corresponding to a current state of the first TRP. As another example, the UE may communicate with the second TRP using a set of parameters, of the configuration, corresponding to a current state of the second TRP. As yet another example, the UE may communicate with at least one of the first TRP or the second TRP based at least in part on a combined state of the first TRP and the second TRP and in accordance with the configuration. For example, the configuration may indicate a set of parameters corresponding to the combined state, or the UE may identify the set of parameters using respective sets of parameters corresponding to individual states of the first TRP and the second TRP. The UE may use the set of parameters to communicate with the first TRP and/or the second TRP (depending on whether the first TRP is active or in a deep sleep and the second TRP is active or in a deep sleep).

As shown by reference number950, the first TRP may switch from the first state to the second state. For example, the first TRP may switch from a first NES state to a second NES state, as described herein. As shown by reference number960, the UE may switch from the first set of parameters (configured for the first state) to the second set of parameters (configured for the second state) based at least in part on the first TRP switching from the first state to the second state. For example, the UE may adjust a transmission or reception from being performed using the first set of parameters to being performed using the second set of parameters. In some aspects, the UE may autonomously determine that the first TRP has switched from the first state to the second state by reference to a configured schedule of states for the first TRP. As another example, the UE may autonomously switch between sets of parameters in accordance with the configured semi-static pattern (such that a set of parameters corresponding to a current state of the first TRP is always in use at the UE). As another example, the UE may determine that the first TRP has switched from the first state to the second state by reference to an indication, received from the first TRP or the second TRP, indicating that the first TRP has switched from the first state to the second state. Thus, the UE may use an adaptive SPS configuration or CG configuration for communication with one or more TRPs, such that the one or more TRPs can dynamically adjust their states (e.g., NES states), which enables improved flexibility for NES operation and reduced overhead relative to explicitly reconfiguring the SPS configuration or CG configuration each time the NES state of a TRP changes.

In some aspects, the UE may switch from the first set of parameters to the second parameters (or from the second set of parameters to the first set of parameters) in a next transmission or reception occasion (e.g., a next SPS occasion or a next CG occasion) after the first TRP switches from the first state to the second state. For example, the UE may receive an indication that the first TRP has switched from the first state to the second state, or may determine according to the semi-static pattern that the first TRP has switched from the first state to the second state. The UE may, in a next transmission or reception occasion, use the second set of parameters for transmission or reception in the next transmission or reception occasion. In some other aspects, the UE may switch from the first set of parameters to the second set of parameters a configured number of transmission or reception occasions after the first TRP switches from the first state to the second state (or the UE is indicated of such a switch). In the above example, (in which the UE switches to the second set of parameters in the next transmission or reception occasion after the switch from the first state to the second state occurs or is indicated to the UE), the configured number of transmission or reception occasions may be 0 (such that the UE switches in a next transmission or reception occasion after the switch from the first state to the second state occurs or is indicated to the UE). In some other aspects, the UE may be configured with a number N indicating a number of transmission or reception occasions, after the switch from the first state to the second state occurs or is indicated to the UE, after which the second set of parameters should be used for transmission or reception. For example, if Nis1, the UE may use the second set of parameters for transmission or reception in a first transmission or reception occasion occurring after a next transmission or reception occasion after the switch from the first state to the second state occurs or is indicated to the UE.
