Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a resource selection method, a power saving processing method, an apparatus, and a device. Background Art

[0002] Currently, some low-capability user equipment, such as mobile phones, home equipment, etc., may need to perform direct or indirect communication between devices through a SideLink (SL). The battery capacity of these devices is relatively low and cannot support long-term use. Moreover, the data volume of some services between devices may be relatively low and the period may be long.

[0003] However, in existing SL transmissions, a device must remain active during the on duration for receiving and / or transmitting. However, during some on durations, the device may have no packets to transmit or be unable to receive scheduling signals. In this case, forcing the user equipment to wake up during the on duration will result in unnecessary power consumption. Also, since SL communication can be multicast, information transmission by user equipment may cause conflicts. Summary of the Invention

[0065] The resource selection method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0066] The method according to an embodiment of the present application is applied to a user device, which may refer to an access terminal, a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device.

[0067] As Figure 2 shown, a resource selection method according to an embodiment of the present application is executed by a first user device and includes:

[0068] Step 201, obtaining a target resource associated with power saving information.

[0069] Here, the power saving information is used to indicate activation or wake-up or deactivation or sleep of a first target user device. If the first user device is denoted as UE1, the second user device may be denoted as UE2. UE2 is a UE that communicates with UE1, receives the signal or channel of UE1, sends a signal or channel to UE1, or, a UE that establishes a connection or group with UE1. The first target user device may be UE1, may be UE2, or may also be other devices other than UE1 and UE2. For this power saving information, there is a target resource associated therewith. In this step, by obtaining the target resource associated with the power saving information, it is used for subsequent resource determination corresponding to the first user device.

[0070] Step 202, determining a first resource from the target resources; wherein, the first resource includes at least one of the following:

[0071] Resources of the power saving information;

[0072] Resources for target transmission;

[0073] Idle resources.

[0074] In this step, the first resource will be determined from the target resources obtained in step 201. Here, the first resource includes at least one of the following: resources of the power saving information; resources for target transmission; idle resources. Then it can also be understood that the type of the first resource is at least one of the above three resources, that is to say, the first resource is used for actual power saving information transmission and / or actual target transmission, and can also be used as an actual idle resource.

[0075] In this way, according to step 201 and step 202, among the obtained target resources associated with power saving information, through the further determined applicable first resource, the first resource can be used for at least one of the transmission of power saving information, the transmission of target transmission, and the vacancy. In this way, the user equipment at both ends of the communication maintains consistent understanding of the resources, so as to achieve coordination and power saving.

[0076] It should be noted that the sleep or wake-up or deactivation or activation mentioned in the embodiments of the present application includes:

[0077] 1. Related to the SL power saving mechanism, which can be interpreted as the sleep or wake-up or deactivation or activation of the SL power saving mechanism;

[0078] 2. Irrespective of the existence of the SL power saving mechanism, but to distinguish whether certain behaviors of the terminal can be carried out normally. For example, if the terminal is activated or woken up, the corresponding behaviors can be carried out; if the terminal is in sleep or deactivated, the corresponding behaviors cannot be carried out.

[0079] In other words, activation or wake-up can be interpreted as the SL power saving mechanism entering the activation time, or, being activated or woken up during the activation time or activation time of the SL power saving mechanism, or it can also mean that a certain behavior can be carried out; for example, at least one of measurement, data reception, control reception, synchronization signal reception, sensing, feedback, etc. can be carried out.

[0080] Deactivation or sleep can be interpreted as the SL power saving mechanism entering the deactivation time, or, being deactivated or put to sleep during the activation time or activation time of the SL power saving mechanism, or it can also mean that a certain behavior is not carried out, such as at least one of not measuring, not receiving data, not receiving control, not receiving synchronization signal, not sensing, not feedback, etc.

[0081] In this embodiment, the power saving information includes at least one of the following:

[0082] Placeholder information;

[0083] Power saving indication command.

[0084] Moreover, the power saving information can be referred to as a Wake Up Signal (WUS), such as SL WUS. That is, SL WUS includes placeholder information and / or power saving indication command. If the power saving information only includes the power saving indication command, the placeholder information can be understood as the associated information of the power saving information, such as the placeholder information of SL WUS; if the power saving information only includes the placeholder information, the power saving indication command can be understood as the associated information of the power saving information, such as the accompanying signaling of SL WUS.

[0085] It should be noted that in the embodiments of the present application, the methods for obtaining the mentioned information can all be:

[0086] a) Obtain information by at least one of the following methods: protocol predefined, preconfigured, base station configured, other user equipment indication, other user equipment recommendation, other user equipment scheduling, and other user equipment configuration;

[0087] b) After obtaining rules by at least one of the methods such as protocol predefined, preconfigured, base station configured, other user equipment indication, other user equipment recommendation, other user equipment scheduling, and other user equipment configuration, further obtain information based on the obtained rules.

[0088] The power saving mechanism obtained by the user equipment specifically includes, for example, SL discontinuous reception (DRX) configuration and / or power saving sensing configuration. The power saving mechanism can be the user's own power saving mechanism or the power saving mechanism of other users; the power saving sensing can be partial sensing, or some simplified or shorter or aperiodic or triggered sensing.

[0089] SL DRX can be used to control at least one of the user equipment's sensing, measurement, monitoring, and transmission of the target object, and the target object includes at least one of the following: control signal / channel, data signal / channel, reference signal, feedback signal / channel, request, response message, etc. For example: Sidelink Control Information (SCI) (including at least one of 1 st stage SCI and 2 nd stage SCI), Physical Sidelink Shared Channel (PSSCH), Physical Sidelink Control Channel (PSCCH), SL Reference Signal (RS), Physical Sidelink Response Channel (PSFCH), Single Synchronization Signal and PBCH Block (S-SSB), Channel State Information (CSI), connection establishment response, etc.

[0090] SL DRX includes at least one of the following times (or can also be referred to as timers): on duration, off duration, Round Trip Time (RTT) timer, inactivity timer, Retransmission timer, long cycle, short cycle.

[0091] SL DRX can be divided into active time and / or inactive time. During the active time, the user equipment performs at least one of measurement, monitoring, and transmission of the target object; during the inactive time, it does not perform at least one of measurement, monitoring, and transmission of the target object. Other channels / signals outside the target object may not be affected by DRX. Optionally:

[0092] The active time and the inactive time may be defined for the target object, that is, the active times of different target objects may be the same or different, and the inactive times of different target objects may be the same or different. (For example, during the active time, the UE can perform the transmission of the first target object, and during the inactive time, it cannot perform the transmission of the second target object. The first target object and the second target object may be the same or different. The corresponding active and inactive times of different target objects may be different), where:

[0093] 1) One assumption is that SCI can be sent at any time.

[0094] 2) The reception of SCI is restricted by the active time of DRX, while the transmission of SCI may be able to be sent during the inactive time, but is restricted by the selection window.

[0095] The active time and the inactive time may be defined for the transmission direction, that is, the active times of sending and receiving may be the same or different, and the inactive times of sending and receiving may be the same or different. Of course, the transmission direction of some target objects may only have an active time and no inactive time.

[0096] Power saving sensing includes a sensing window and a selection window.

[0097] The SL DRX activation time includes at least one of the on duration, the running time of the inactivity timer (when the inactivity timer is running), the running time of the retransmission timer (when the retransmission timer is running), the running time of T400, and the period of the sidelink CSI latency bound report (sl-LatencyBoundCSI-Report).

[0098] The SL DRX inactivity time includes at least one of the off duration and the running time of the RTT timer.

[0099] The power saving sensing activation time includes at least one of the sensing window and the selection window.

[0100] The power saving sensing inactivity time includes at least one of the part that is not the partial sensing window (e.g., the part between or outside the partial sensing windows), the part that is not the selection window (e.g., the part outside the selection window), and the time when there is no sensing.

[0101] The measurable resource can be a (logical) resource during the activation time (for receiving or transmitting the corresponding one). Preferably, it is at least the activation time for receiving on the control channel and / or data channel, such as the activation time for receiving the PSCCH and / or PSSCH.

[0102] The non-measurable resource can be a resource during the inactivity time. Preferably, it is at least the inactivity time for receiving on the control channel and / or data channel, such as the inactivity time for receiving the PSCCH and / or PSSCH.

[0103] The resources mentioned in this application include time-domain and / or frequency-domain resources. The frequency-domain resources can be one or more sub-channels / RBs / interlaces / combs (on one or more time-domain resources). The time-domain resources can be one or more symbols / slots / mini-slots / milliseconds (ms) / sub-frames / frames / peridoities. The time-domain resources can be physical time-domain resources or logical time-domain resources. For example, a slot can be a physical slot or a logical slot. The time-frequency resources can be single-slot resources that occupy X sub-channels or RBs.

[0104] In this application, "corresponding" can also be interpreted as having a mapping relationship, having an association relationship, being associated, etc.

[0105] In this application, the duration can be understood as the number of resources included / the number of measurable resources / the number of logical resources.

[0106] The embodiments of this application are applicable to power saving in the SL scenario under the authorized frequency band and / or the SL scenario under the unlicensed frequency band. This solution can be applicable to scenarios where either end of the transceiver UE needs to save energy (for example, vehicle-to-pedestrian network (V2P)), or scenarios where both ends need to save energy (for example, peer-to-peer network (P2P), or communication through SL or other interfaces such as PIOT).

[0107] In the embodiments of this application, a UE may perform SL reception or transmission at different time points, that is, the UE is respectively the transmitting UE (TX UE) or the receiving UE (RX UE).

[0108] Among them, the ways in which the power-saving information is associated with the target resources include at least one of the following:

[0109] There is a corresponding relationship between the power-saving information and at least part of the target resources;

[0110] There is a corresponding relationship between the resources of the power-saving information and at least part of the target resources;

[0111] The power-saving information and the target transmissions on at least part of the target resources all need to be transmitted;

[0112] The power-saving information indicates at least part of the target resources.

[0113] Here, both the power-saving information and the target transmission on at least part of the target resources need to be transmitted, that is, the power-saving information is transmitted together with the target transmission on at least part of the target resources. Specifically, the power-saving information and the target transmission can be carried out on the same resources (such as time-domain resources and / or frequency-domain resources); or the power-saving information and the target transmission can be on different time-domain resources and / or frequency-domain resources, but both the power-saving information and the target transmission need to be transmitted. Among them, the number ratio of the power-saving information to the target transmission can be one-to-many, many-to-one or one-to-one. And when the power-saving information and the target transmission are on the same time-domain resources and / or frequency-domain resources, it can also be interpreted that the target transmission carries the power-saving information. Of course, regardless of whether the power-saving information and the target transmission are on the same resources, if the power-saving information does not indicate / reserve the target resources for joint transmission, further preferably, the target resources may be obtained through configuration / pre-configuration / protocol regulations, etc. For example, if the power-saving information is transmitted on Resource 1 and the protocol stipulates that Resource 2 corresponds to Resource 1, then Resource 2 is the target resource associated with the power-saving information.

[0114] For the power-saving information indicating at least part of the target resources, the power-saving information and the part of the target resources it indicates may or may not have a corresponding relationship or be transmitted together, which will not be listed one by one here.

[0115] Among them, the types of target resources include at least one of the following:

[0116] Resources for placeholder information;

[0117] Resources for power-saving indication commands;

[0118] Resources for target transmission;

[0119] Idle resources.

[0120] It can also be said that the uses of the target resources include at least one of the following: transmission of placeholder information; transmission of power-saving indication commands; transmission of target transmission; idling. Of course, since the target resources can also be candidate resources for at least one of the placeholder information, power-saving indication commands and target transmission, they are not necessarily used for information transmission. In addition, the types of target resources also include resources for power-saving information, that is, the uses of the target resources also include the transmission of power-saving information.

[0121] Among them, the placeholder information and the power saving indication command can be either the placeholder information and the power saving indication command in the current power saving information, that is, the current placeholder information and the current power saving indication command; or the placeholder information and the power saving indication command in other power saving information, that is, other placeholder information and other power saving indication commands. The target transmission can be at least one of target data and target feedback. The target data can be interpreted as the data transmission indicated / reserved by the power saving information (placeholder information and / or power saving indication command), which may be any data content or specific data content; the target feedback can be interpreted as the feedback related to the power saving information. Specifically, it can be a Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK), or a response message.

[0122] And the vacancy can be understood as that the target resource is not used for transmission. Then the vacant resources include at least one of the following: (the device sending the power saving information) does not transmit the first signal / channel, or any signal / channel, on the vacant resources; (a specific device receiving the power saving information or any device receiving the power saving information) cannot transmit the second signal / channel, or any signal / channel, on the vacant resources.

[0123] The content of the target resource includes:

[0124] A specific message, or any message;

[0125] Among them, the specific message includes at least one of the following:

[0126] A message with target content;

[0127] A message corresponding to the first target user equipment;

[0128] A redundant message;

[0129] An invalid message;

[0130] A Flag message;

[0131] A Bacon message;

[0132] A valid message.

[0133] Here, the target content is the message content with specific meaning. The redundant message or the invalid message can be a fixed-length or all-0 bit string occupying a fixed resource size, or a fixed-length or all-1 bit string occupying a fixed resource size. The valid message can be a service-related packet / TB, MAC CE, RRC signaling, etc. The any message can be understood as the message whose bearer content is determined by the UE itself, or a message corresponding to any UE.

[0134] The content of the target transmission bearer can be indicated by the power saving information.

[0135] That is, the content of the above-mentioned target transmission bearer is indicated by the placeholder information and / or the power saving indication command. For example, it indicates that the target transmission is a valid message, or indicates that the target transmission is a message corresponding to the target UE. The target UE can be understood as the first target user equipment.

[0136] Based on the above-mentioned target resources specifically, step 202 includes the following methods:

[0137] 1) Determine the target resources associated with the power saving information, and select K first resources from them for the transmission of other power saving information. For example, determine the target resources associated with the placeholder information, and select K first resources from them for the transmission of the power saving indication command; determine the target resources associated with the power saving indication command, and select K first resources from them for the transmission of the placeholder information.

[0138] 2) Determine the target resources associated with the power saving information, and select K first resources from them for the target transmission (such as target data).

[0139] 3) Determine the target resources associated with the power saving information, and select K first resources from them as idle resources.

[0140] To determine the first resources, optionally, in this embodiment, step 202 includes:

[0141] In the target resources, determine the first resources indicated by the power saving information.

[0142] Here, if the first resources are indicated by the power saving information, then through the indication of the power saving information, the first resources can be determined in the target resources. And as mentioned above, the power saving information indicates at least some of the target resources, so one case where the power saving information indicates at least some of the target resources is that the power saving information indicates the first resources.

[0143] On the other hand, optionally, step 202 includes:

[0144] In the target resources, determine the first resources corresponding to specific target parameters; where the specific target parameters are one or more of the target parameters.

[0145] Here, the target parameters can also be understood as preset parameters, and can be one or more. Specifically, at least some of the target resources corresponding to the specific target parameters are the first resources.

[0146] Optionally, the target parameters include at least one of the following:

[0147] The identifier of the user equipment; for example, the identifier of the first target user equipment;

[0148] Communication-related location information;

[0149] Power-saving mechanism;

[0150] Process information;

[0151] Resource pool information;

[0152] Carrier information;

[0153] Bandwidth part information;

[0154] Identifier of power-saving information;

[0155] Resource information of power-saving information;

[0156] Relevant information of the target resource.

[0157] Here, the identifier (ID) of the user equipment may be a resource identifier (source ID), a destination user equipment identifier (destination ID), a member identifier (member ID), or a group identifier (group ID), etc. The location information related to communication may be a communication range, which can be obtained through a zone address (zone ID). The power saving mechanism may include at least one of the following: activation or wake-up; deactivation or sleep; extension of activation or wake-up time; extension of deactivation or sleep time. If the power saving mechanism is set with a corresponding identifier, the power saving mechanism included in the target parameter is the power saving mechanism ID, such as the DRX configuration ID of the target UE. The process information may be a process ID (Process ID), the resource pool information may be a resource pool ID, the carrier information may be a carrier ID, and the bandwidth part information may be a bandwidth part ID (BWP ID). The resource information of the power saving information may include at least one of the following: power saving information resource ID; power saving information resource set ID; the number of power saving information resources in the power saving information resource set; the time domain resource ID where the power saving information is located; the frequency domain resource ID where the power saving information is located; the code domain resource ID where the power saving information is located; the starting frequency domain resource where the power saving information is located, such as the starting sub-channel or the ending RB; the starting frequency domain resource where the power saving information is located, such as the ending sub-channel or the ending RB; the starting time domain resource where the power saving information is located; the ending time domain resource where the power saving information is located; the number of frequency domain resources occupied by the power saving information; the number of time domain resources occupied by the power saving information. The relevant information of the target resource may include at least one of the following: target resource ID; target resource set ID; the number of target resources included in the target resource set; the time domain resource ID where the target resource is located; the frequency domain resource ID where the target resource is located; the code domain resource ID where the target resource is located; the starting frequency domain resource where the target resource is located, such as the starting sub-channel or the ending RB; the starting frequency domain resource where the target resource is located, such as the ending sub-channel or the ending RB; the starting time domain resource where the target resource is located; the ending time domain resource where the target resource is located; the number of frequency domain resources occupied by the target resource; the number of time domain resources occupied by the target resource.

[0158] Thus, taking the target parameter as the identifier of the user equipment as an example, the target parameter includes the identifier of one or more or within the target user equipment group or any user equipment. And the specific target parameter is the identifier related to the first target user equipment. Preferably, the identifier related to the first target user equipment is the identifier of some user equipment in the first target user equipment.

[0159] Again, taking the target parameter as the identifier of the user equipment as an example, the target parameter includes the identifier of one or more or within the target user equipment group or any user equipment. And the specific target parameter is the identifier of the first user equipment and / or the identifier of the second user equipment.

[0160] Taking the identification of the first target user device as the target parameter as an example, the target parameter includes the identification of one or more user devices, and the one or more user devices are the first target user device. The specific target parameter is the identification of at least some of the user devices in the first target user device. Preferably, at least some of the user devices in the first target user device may include the first user device or user devices having an association relationship with the first user device.

[0161] To determine the first resource based on the target parameter, optionally, before step 202, it further includes: obtaining target parameter indication information, and the target parameter indication information indicates at least some of the target parameters required to determine the first resource.

[0162] For the target parameter, optionally, there is a corresponding relationship between the target parameter and the second resource; wherein, the second resource includes at least one of the following:

[0163] Resources for power saving information;

[0164] The first resource;

[0165] The target resource.

[0166] In addition, in this embodiment, the second resource can also be represented by the identification of the second resource. Optionally, the identification of the second resource is determined by at least one of the following methods:

[0167] Determined according to the numbers sorted in the time domain for at least some of the second resources;

[0168] Determined according to the numbers sorted in the frequency domain for at least some of the second resources;

[0169] Determined according to the numbers sorted in the code domain for at least some of the second resources.

[0170] Specifically, the sorting of at least some of the second resources in the time domain, frequency domain, and code domain can be in ascending order or in descending order.

[0171] In this embodiment, the second resource ID includes at least one of the ID of the resource for power saving information, the ID of the target resource / occasion of the target resource / set of the target resources associated with the power saving information, and the ID of the power saving information.

[0172] Optionally, when the second resource is the resource for power saving information, the identification of the second resource is the identification of the resource for power saving information or the identification of the power saving information;

[0173] When the second resource is the target resource, the identification of the second resource is the identification of the target resource.

[0174] The second resource is represented by a second resource ID. Optionally, the corresponding relationship is the correspondence between the target parameter and the identifier of the second resource. That is, the corresponding relationship between the target parameter and the second resource is the correspondence between the target parameter and the identifier of the second resource.

[0175] Specifically, the correspondence between the target parameter and the identifier of the second resource includes at least one of the following:

[0176] The result of taking the modulus of the target parameter corresponds to the ID of the second resource;

[0177] The result of dividing the target parameter by a specific value corresponds to the ID of the second resource;

[0178] The ID of the second resource corresponds to the sum of at least two target parameters.

[0179] In addition, optionally, in this embodiment, the power saving information and / or the target resource are carried on at least one of the following:

[0180] Physical sidelink control channel PSCCH;

[0181] Physical sidelink feedback channel PSFCH;

[0182] Physical sidelink shared channel PSSCH;

[0183] Sequence.

[0184] Specifically, the power saving information and / or the target resource are carried on the PSCCH, such as 1 st stage SCI (e.g., SCI format1-A), the xth SCI format, x> = 0 or x is a certain letter. The power saving information and / or the target resource are carried on the PSSCH, such as 2 nd stage SCI, the data part of the PSSCH, the yth SCI format. Preferably, the placeholder information and the power saving indication command included in the power saving information are both transmitted on at least part of the resources of the PSCCH, so that both can be demodulated by the PSCCH DMRS.

[0185] The power saving information and / or the target resource can also be carried on other channels / signals other than the above, such as channels / signals dedicated to the power saving information.

[0186] Optionally, the frequency domain resources of the power saving information and / or the target resource include at least one of the following:

[0187] At least part of the frequency domain resources in the target resource block;

[0188] At least part of the frequency domain resources in the target subchannel.

[0189] Here, the target resource block (RB) can also be understood as the remaining RB. Then, at least part of the frequency-domain resources in the target resource block, that is, at least part of the frequency-domain resources in the remaining RB, for example, part of the RBs in the remaining RB. And the target subchannel can be understood as a preset subchannel, including one or more subchannels.

[0190] Among them, the target resource block includes at least one of the following:

[0191] The resource block with the first identifier in the resource pool or bandwidth part or carrier;

[0192] In the resources occupied by the PSSCH scheduled by the first sidelink control information (SCI), the resource blocks of the subchannels other than the subchannels occupied by the SCI;

[0193] In the resources occupied by the PSSCH scheduled by the first SCI, the resource blocks other than the resource blocks occupied by the SCI;

[0194] In the resources of the bandwidth part, the resource blocks other than the resource pool;

[0195] In the resources of the bandwidth part, the resource blocks other than the resources corresponding to the PSFCH or the PSFCH bitmap;

[0196] In the resources of the resource pool, the resource blocks other than the resources occupied by all subchannels or part of the subchannels;

[0197] In the resources of the resource pool, the resource blocks other than the resources corresponding to the PSFCH or the PSFCH bitmap.

[0198] Here, the first identifier can be the maximum index. Then, the resource block with the first identifier in the resource pool or bandwidth part or carrier, that is, the H RBs with the maximum index of the resource pool / bwp / carrier. The first SCI is a 1 st stage SCI. Then, in the subchannels occupied by the PSSCH scheduled by the first SCI, the resource blocks of the subchannels other than the subchannels occupied by the first SCI, that is, the resource blocks of the remaining subchannels after excluding the subchannels occupied by the 1 st stage SCI from the subchannels occupied by the PSSCH scheduled by the 1 st stage SCI; Similarly, in the subchannels occupied by the PSSCH scheduled by the first SCI, the resource blocks other than the resource blocks occupied by the first SCI, that is, the resource blocks of the remaining subchannels after excluding the 1 st stage SCI from the subchannels occupied by the PSSCH scheduled by the 1 stThe remaining RBs after stage SCI occupies the RBs. Among the resource blocks in the bandwidth part, the resource blocks other than those in the resource pool, that is, the remaining RBs in the RBs included in the BWP after excluding the RBs occupied by the resource pool. Among the resource blocks in the resource pool, the resource blocks other than those occupied by all sub-channels or some sub-channels, that is, the remaining RBs in the RBs included in the resource pool after excluding the RBs occupied by all sub-channels or some sub-channels. Among the resource blocks in the resource pool, the resource blocks other than those corresponding to the PSFCH or the PSFCH bitmap, that is, the remaining RBs in the RBs included in the BWP after excluding the RBs corresponding to the PSFCH or the RBs corresponding to the PSFCH bitmap. Among the resource blocks in the bandwidth part, the resource blocks other than those corresponding to the PSFCH or the PSFCH bitmap, that is, the remaining RBs in the RBs included in the resource pool after excluding the RBs corresponding to the PSFCH or the RBs corresponding to the PSFCH bitmap. For example, if the BWP includes 275 RBs, the sub-channel size S = 10 RBs, and the number of sub-channels N = 20, then 275 - S * N = 75 RBs. At least some of these 75 remaining RBs are frequency-domain resources that can be used to transmit power-saving information.

[0199] In this way, some unused parts of the frequency-domain resources can be utilized, and compatibility can be achieved.

[0200] For the target sub-channel, optionally, the target sub-channel includes at least one of the following:

[0201] Among the resources occupied by the PSSCH scheduled by the first SCI, the sub-channels other than the sub-channels occupied by the first SCI;

[0202] Among the resources occupied by the PSSCH scheduled by the first SCI, the sub-channels other than the sub-channels occupied by the first SCI;

[0203] In the bandwidth part, the sub-channels other than the resource pool;

[0204] In the bandwidth part, the sub-channels other than the resources corresponding to the PSFCH or the PSFCH bitmap;

[0205] In the resource pool, the sub-channels other than the resources occupied by all sub-channels or some sub-channels;

[0206] In the resource pool, the sub-channels other than the resources corresponding to the PSFCH or the PSFCH bitmap;

[0207] The sub-channels in the resource pool whose frequency domain satisfies the first condition;

[0208] The sub-channels with the second identifier;

[0209] The sub-channels with the first number of resource blocks;

[0210] A sub-channel that at least includes the sub-channel where the power saving information is located.

[0211] Among them, if the first condition is the lowest N1 sub-channels in the frequency domain, the target sub-channels are the lowest N1 sub-channels in the frequency domain of the resource pool. For example, when N1 = 2, the target sub-channels are the lowest and the second lowest two sub-channels in the frequency domain of the resource pool. Of course, the first condition can also be the highest N3 sub-channels in the frequency domain, and the target sub-channels are the highest N3 sub-channels in the frequency domain of the resource pool. For example, when N3 = 2, the target sub-channels are the highest and the second highest two sub-channels in the frequency domain of the resource pool.

[0212] If the second identifier is the smallest index, the target sub-channel is the sub-channel with the smallest index. Of course, if the second identifier also corresponds to the number N2 of sub-channels, the target sub-channels are the N2 sub-channels with the smallest index. For example, when N2 = 2, the target sub-channels are the two sub-channels with index = 0 and 1. Of course, the second identifier can also be the largest index and corresponds to the number N4 of sub-channels, then the target sub-channels are the N4 sub-channels with the largest index. For example, when N4 = 2 and the largest index of the sub-channel is 9, the target sub-channels are the two sub-channels with index = 9 and 8.

[0213] The first quantity defines the number of RBs of the sub-channel. Specifically, this first quantity is determined based on the number of all or part of the sub-channels, the number of RBs of each sub-channel, and the number of target sub-channels. For example, if there are N5 target sub-channels and the target sub-channels are the N5 sub-channels with the smallest number of RBs. For example, if N5 = 5 and the first smallest RB number is the smallest RB number, the first quantity is determined by the RB number of the sub-channel with the fifth smallest RB number.

[0214] The sub-channel that at least includes the sub-channel where the power saving information is located can be the sub-channel where the power saving information is located, that is, the (candidate) frequency domain resource of the target resource is the sub-channel where the power saving information is located. Preferably, in this case, the target resource is an idle resource; it can also be multiple (such as I) sub-channels including the sub-channel where the power saving information is located, that is, the (candidate) frequency domain resource of the target resource is I sub-channels including the sub-channel where the power saving information is located. Preferably, the I sub-channels start or end with the sub-channel where the power saving information is located.

[0215] Of course, the target sub-channel can also be any sub-channel.

[0216] Optionally, the power saving information and / or the time domain resource of the target resource includes at least one of the following:

[0217] In the first symbol, the symbols except at least part of the symbols of the first channel or signal;

[0218] At least part of the symbols in the symbols for automatic gain control AGC;

[0219] The first symbol in the symbols for sidelink transmission;

[0220] At least some of the symbols in the PSCCH symbols;

[0221] At least some of the symbols in the SCI symbols.

[0222] Wherein, if the first symbol is a symbol for SL transmission, then in the first symbol, at least some of the symbols other than at least some of the symbols of the first channel / signal (preset channel / signal), that is, the remaining symbols after removing at least some of the symbols of the preset channel / signal from the symbols for SL. Correspondingly, the time domain resources of the power saving information and / or the target resource are the remaining symbols after removing the time domain symbols of the preset channel / signal (candidate) from the symbols that can be used for SL. In this way, it is avoided that the introduced power saving information will cause too strong interference to the preset channel / signal, or avoid that the power saving information wipes out the existing preset channel / signal. Here, the first channel / signal includes at least one of the following: 1 st stage SCI; 2 nd stage SCI; DMRS; CSI-RS; PT-RS; P-RS; PBSCH; S-PSS; S-SSS. The DMRS can be at least one of the PSSCH DMRS and the PSCCH DMRS. For example, the (candidate) symbol of the power saving information is at least one of the remaining symbols in the symbol where the PSSCH is located that do not contain the PSSCH DMRS.

[0223] And at least some of the symbols in the PSCCH or SCI symbols, specifically, the time domain resources of the power saving information (i.e., the (candidate) time domain symbols) are the 2nd and 3rd symbols in the symbols for SL. In this way, it is possible to reuse the design of 1 st stage SCI for the design of the power saving information.

[0224] In addition, optionally, in this embodiment, at least one of the following of the resources of the power saving information and / or the target resource is different:

[0225] The carried channel or signal;

[0226] Frequency domain resources;

[0227] Time domain resources;

[0228] Code domain resources.

[0229] Taking the different carried channels as an example, it is preferred that the power saving information is transmitted on the PSCCH and the target resource is on the PSSCH.

[0230] Among them, the power saving information includes placeholder information and / or a power saving indication command. Optionally, at least one of the following is different between the resources of the placeholder information and the resources of the power saving indication command:

[0231] The carried channel or signal;

[0232] Frequency domain resources;

[0233] Time domain resources;

[0234] Code domain resources.

[0235] For example, the (candidate) time domain / frequency domain resource positions of the placeholder information and the power saving indication command can be different or the same, and the time domain / frequency domain resource quantities can be different or the same. The (candidate) time domain / frequency domain resources of the placeholder information and the power saving indication command can be defined using the same method as the time domain / frequency domain resources of the above-mentioned power saving information, or can be defined using different methods, and the values of at least one of N1, N2, N3, N4, and N5 corresponding to the placeholder information and the power saving indication command may also be the same or different. Specifically, if the frequency domain resource configurations of the placeholder information and the power saving indication command can be obtained (configured) separately, separate parameters can be used for configuration or pre-configuration; or they can be obtained (configured) together, for example, using the same parameter for configuration or pre-configuration, then:

[0236] The (candidate) frequency domain resource of the placeholder information is part of the resources of the sub-channel with the smallest index, and the (candidate) frequency domain resource of the power saving indication command is part of the resources of the sub-channel with the smallest index;

[0237] The (candidate) frequency domain resource of the placeholder information is part of the resources of the sub-channel with the lowest index, and the (candidate) frequency domain resource of the power saving indication command is part of the resources of the two sub-channels with the largest index;

[0238] The (candidate) time domain resource of the placeholder information is the (candidate) symbol of PSCCH, that is, the 2nd and 3rd symbols among the symbols that can be used for SL, and the (candidate) time domain resource of the power saving indication command is part of the remaining symbols of the (candidate) symbols of PSSCH that do not include DMRS and 2 nd stage SCI;

[0239] The (candidate) time domain resource of the placeholder information is the symbol that can be used for AGC, that is, the 1st symbol among the symbols that can be used for SL, and the (candidate) time domain resource of the power saving indication command is the (candidate) symbol of PSCCH, that is, the 2nd and 3rd symbols among the symbols that can be used for SL.

[0240] Another example is that the placeholder information and the power saving indication command are carried on different channels or signals: One possibility is that the placeholder information is on PSCCH or 1 stIt is carried in the stage SCI, and the power saving indication command is carried in the PSSCH or the 2 nd stage SCI or the 3rd SCI.

[0241] In addition, optionally, in this embodiment, the time domain resources of the power saving information satisfy at least one of the following conditions:

[0242] The number of repetitions in the time domain is not less than the second quantity;

[0243] The number of repetitions in the time domain is the third quantity;

[0244] It occupies Y time domain units, and Y is equal to the number of time domain units used for sidelink transmission.

[0245] Therefore, the time domain resources of the power saving information can be that the power saving information is repeated R times in the time domain (that is, the second quantity is less than or equal to R, or the third quantity is R), or the power saving information occupies Y time domain units.

[0246] For example, the design of the time domain resources of the power saving information includes at least one of the following: occupying L symbols and repeating (repeat) R times at the granularity of L symbols; occupying Y symbols. Optionally, R = Y / L or R is the value obtained by rounding the result of Y divided by L. As Figure 3 As shown, in Example 1, the time domain resources of the power saving information (the shaded part in the figure) occupy L symbols and repeat R times at the granularity of L symbols, where R = 5; in Example 2, the time domain resources of the power saving information occupy Y symbols; in Example 3, the time domain resources of the power saving information occupy Y symbols and repeat R times at the granularity of L symbols, where R = 3.

[0247] Optionally, there is no multiplexing between the power saving information and the second channel or signal.

[0248] Among them, no multiplexing between the power saving information and the second channel or signal includes:

[0249] There is no frequency division multiplexing between the power saving information and the second channel or signal; or,

[0250] There is no overlap between the time domain resources of the power saving information and the time domain resources of the second channel or signal;

[0251] Among them, the second channel or signal is a channel or signal other than the power saving information.

[0252] For example, the second channel / signal is a dedicated slot or symbol for power saving information. Another example is that when the power saving information is at the tail or head of the SL slot, the second channel / signal can be the part of the SL slot other than the tail or head. At this time, there is no multiplexing between the power saving information and the second channel / signal.

[0253] Optionally, the sequences carried on different target resources are different.

[0254] It can also be understood that the sequences carried on different target time-domain resources are different, where the target time-domain resources are the time-domain resources of the target resources; the sequences carried on different target frequency-domain resources are different, where the target frequency-domain resources are the frequency-domain resources of the target resources. The ways in which the sequences are different include at least one of the following: different basic sequences; different cyclic shifts; different polynomials.

[0255] Optionally, in this embodiment, the method further includes:

[0256] Obtaining information about the power-saving information and / or information about the target resources.

[0257] In this way, based on the information about the power-saving information obtained (such as resource information), the (candidate) resources for the power-saving information can be determined; based on the information about the target resources obtained (such as resource information), the (candidate) target resources can be determined.

[0258] The information about the power-saving information and / or the information about the target resources includes at least one of the following:

[0259] Information about frequency-domain resources;

[0260] Information about time-domain resources;

[0261] The period of the resources;

[0262] The number of resources;

[0263] The priority of the resources;

[0264] The proportion in the resource pool or within a given time.

[0265] Here, the information about the frequency-domain resources can specifically be the number / position of the occupied sub-channels / RBs / interlaces / combs, and / or information such as time-domain offset, etc. The time-domain resources can specifically be the number / position / periodicity of the occupied symbols / slots / mini-slots / ms / sub-frames / frames, and / or information such as frequency-domain offset, etc.

[0266] Optionally, the acquisition of the target resources is determined by at least one of the following ways: configuration; pre-configuration; pre-definition.

[0267] Optionally, the method further includes:

[0268] Obtaining transmission parameters;

[0269] Performing transmission on the first resource according to the transmission parameters.

[0270] Among them, for the first resources corresponding to different uses, their transmission parameters may be the same or different.

[0271] The first resource is the resource to be transmitted. When the target transmission is the target data, the transmission parameters include at least one of the bearer content, new transmission or retransmission indication, Priority, process ID, TB size, the value of PSFCH indication, MCS, MCS table, rank, SCI format, DMRS pattern, DMRS density, number of ports, period, number of occupied time domain resources, number of occupied frequency domain resources, position of occupied time domain resources, position of occupied frequency domain resources, upper or lower limit of the number of occupied resources, Beta_offset, source ID, destination ID, HARQ feedback enabled / disabled indicator, Cast type, CSI request indication, and Zone ID, and can be configured, pre-configured, or predefined. When the target transmission is the target feedback, the transmission parameters include at least one of the bearer content (such as HARQ-ACK status), new transmission or retransmission indication, Priority, sequence used, cyclic shift, process ID, MCS, MCS table, rank, SCI format, DMRS pattern, DMRS density, number of ports, period, number of occupied time domain resources, number of occupied frequency domain resources, position of occupied time domain resources, position of occupied frequency domain resources, upper or lower limit of the number of occupied resources, Beta_offset, source ID, destination ID, Cast type, and Zone ID, and can be configured, pre-configured, or predefined.

[0272] In this embodiment, preferably, the (candidate) time domain resources of the power saving information may be located before / during / after the activation time.

[0273] In this embodiment, 1 st stage SCI can be SCI format 1-x, such as 1-A; 2 nd stage SCI can be SCI format 2-y, such as 2-A and / or 2-B.

[0274] In this embodiment, when at least one of the following is satisfied, the fields related to the power saving information and 2 nd the SCI format are invalid or set to special values:

[0275] The power saving information reuses 1 st stage SCI format and is transmitted on the PSCCH;

[0276] The power saving information indicates at least one target resource.

[0277] Wherein, the special value is all 1s or all 0s or fixed content. At this time, there may be no 2 nd For SCI format transmission, it is necessary to invalidate the fields related to 2 nd SCI format. Actually, there is a virtual 2 nd SCI format.

[0278] For the AGC / GP of the power saving information, AGC symbols may be necessary, but GP symbols may not be necessary, because the transmission direction between the placeholder information and the power saving command may remain unchanged for a UE. Then:

[0279] Optionally, there are at least time domain units (such as symbols) for AGC and for GP between the time domain resources of two adjacent power saving information.

[0280] Optionally, there are at least time domain units (such as symbols) for GP between the time domain resources of two adjacent power saving information.

[0281] Optionally, there are at least time domain units (such as symbols) for AGC between the time domain resources of two adjacent power saving information.

[0282] Optionally, the time domain resources of two adjacent power saving information are continuous,

[0283] Furthermore, the first A time domain units (such as A symbols) of the time domain resources of the power saving information can be used as time domain units (such as symbols) for AGC.

[0284] Optionally, there are at least time domain units (such as symbols) for AGC and for GP between the time domain resources of the placeholder information and the power saving indication command.

[0285] Optionally, there are at least time domain units (such as symbols) for GP between the time domain resources of the placeholder information and the power saving indication command.

[0286] Optionally, there are at least time domain units (such as symbols) for AGC between the time domain resources of the placeholder information and the power saving indication command.

[0287] Optionally, the time domain resources of the placeholder information and the power saving indication command are continuous,

[0288] Further optionally, the first A1 time domain units (such as symbols) of the time domain resources of the placeholder information can be used for AGC;

[0289] Further optionally, the first A2 time domain units (such as symbols) of the time domain resources of the power saving indication command can be used for AGC.

[0290] Optionally, the time domain units that can be used for GP (guard period) can also be at least one of the time domain units for transceiver conversion, the time domain units for power adjustment, the time domain units for technology switching, and the time domain units for RF adjustment.

[0291] For the above power saving information (placeholder information and / or power saving indication command), there may be the following several schemes for the relationship between the target resources and the target transmission (only for example in the figure, not representing the only implementation of the scheme):

[0292] 1) The power saving information can use the resources of 1 st stage SCI or PSCCH, and the power saving information has no associated target resources.

[0293] The power saving information can use the 1 st stage SCI format (but may use PSCCH resources or not use PSCCH resources, such as using at least part of the remaining RBs) or directly use at least part of the resources of PSCCH for transmission, for example, transmit on the 2nd and 3rd symbols in the symbols that can be used for SL. Here, there is no restriction on whether the power saving information contains placeholder information.

[0294] One possible implementation method is that the power saving information is transmitted on the resources of PSCCH and occupies a frequency domain resource less than or equal to one subchannel. At this time, the power saving information is similar to a standalone 1 st stage SCI. Another possible implementation method is that the power saving information is transmitted on the remaining RBs. Further optionally, the power saving information reuses the SCI format. At this time, the power saving information is similar to a standalone SCI.

[0295] As Figure 4 shown, a 1 st stage SCI occupies the PSCCH resources on subchannel #1 and schedules data, while the power saving information (the shaded part in the figure, the same below) uses the PSCCH resources on subchannel #0.

[0296] As Figure 5 shown, the power saving information can be transmitted on the remaining subchannels that are not occupied by the 1 st stage SCI within the data part bandwidth scheduled by the 1 st stage SCI.

[0297] As Figure 6 shown, the power saving information can be in 1st Within the data part bandwidth of the stage SCI scheduling, it is not transmitted on the RBs occupied by the stage SCI. st

[0298] In this way, the detection complexity of the power saving information is low, and the power saving information may be determined during reception / sensing.

[0299] 2) The power saving information can use the resources of the 1 st stage SCI or PSCCH, and there are target resources associated with the power saving information.

[0300] The power saving information can use the 1 st stage SCI format (but may or may not use the PSCCH resources, for example, use at least part of the remaining RBs) or directly use at least part of the PSCCH resources for transmission, for example, transmit on the 2nd and 3rd symbols in the symbols available for SL. Here, there is no restriction on whether the power saving information contains placeholder information.

[0301] One possible implementation method is that the power saving information is transmitted on the resources of the PSCCH and the occupied frequency domain resources are less than or equal to one subchannel, and the power saving information is associated with the target resources. Another possible implementation is that the power saving information is transmitted on the remaining RBs, and the power saving information is associated with the target resources. Further optionally, the power saving information reuses the SCI format.

[0302] 2a, if the target resources corresponding to the power saving information are associated by agreeing on the method of the target resources, the power saving information at this time is similar to a standalone 1 st stage SCI, although there are accompanying target resources, for example, the protocol stipulates that as Figure 7 in the power saving information will be associated with a target resource that occupies 2 subchannels and the starting subchannel is the same as the subchannel where the power saving information is located. The power saving information may not indicate the target resource. After the receiving user detects and identifies the power saving information, the target resources in the figure are determined. In Figure 7 the target resources are on the PSSCH.

[0303] Optionally, as Figure 7 shown, if the target resources are associated by the method of indicating the target resources by the power saving information, the power saving information at this time is similar to a 1 st stage SCI that schedules the PSSCH resources.

[0304] Optionally, as Figure 27As shown, the frequency domain resource of the target resource can also be the subchannel where the power saving information is located, that is, the power saving information is associated with a target resource that occupies 1 subchannel and is the subchannel where the power saving information is located. The power saving information can indicate this target resource or not indicate this target resource.

[0305] In this way, the detection complexity of the power saving information is low, and it may be possible to determine the power saving information during reception / sensing. And the associated power saving information can be used for data transmission, or for transmitting part of the power saving indication information (especially when the number of bits of the power saving information is large), or it can also not be used for transmission.

[0306] Furthermore, if the resource indication method in the existing setting is reused and the target resource is indicated in the resource indication field in the power saving information, then the resource indication field in the power saving information can be recognized by other UEs at this time. Other UEs will think that the target resource has been occupied by someone, thus avoiding other UEs from using the target resource and causing conflicts.

[0307] 2b, such as Figure 8 and 9 As shown, the power saving information and the target resource are on the PSCCH in the figure. Optionally, if the target resource is associated by the method of indicating the target resource through the power saving information, the power saving information at this time is similar to an SCI that schedules the PSCCH resource.

[0308] In this way, the detection complexity of the power saving information is low, and it may be possible to determine the power saving information during reception / sensing.

[0309] 3) The power saving information is transmitted in the 2 nd stage SCI or the Nth stage SCI or the PSSCH.

[0310] Among them, the power saving information can use the resources of the 2nd stage SCI or the Nth stage SCI or the PSSCH for transmission. Here, there is no restriction on whether the power saving information contains placeholder information.

[0311] For example, as Figure 10 shown, the power saving information is carried in the 2 nd SCI or the Nth stage SCI or the PSSCH, where the Nth stage SCI is the control signaling (such as SCI or MAC CE or RRC) indicated by the 1 st stage SCI or the 2 nd stage SCI or other SCI. Further optionally, N>2 or N is not 2-A and 2-B.

[0312] For example, as Figure 11 shown, the power saving information is carried in the TB that can be used for PSSCH bearing.

[0313] For example, as Figure 12 shown, some power saving information is also carried in the target resource associated with the power saving information.

[0314] In this way, more bits can be carried in the power saving information.

[0315] 4) The power saving information is on the PSCCH or PSFCH, and the target resource is on the PSFCH symbol.

[0316] For example, as Figure 13 shown, the placeholder information can use the 1 st stage SCI format (but may use the PSCCH resource or not use the PSCCH resource, for example, use at least part of the remaining RBs) or directly use at least part of the resources of the 1 st stage SCI or PSCCH for transmission, for example, transmitted on the 2nd and 3rd symbols in the symbols available for SL. The associated target resource uses the part of the frequency domain resource outside the RBs used by the PSFCH on the symbol where the PSFCH is located or uses at least part of the resources of the PSFCH.

[0317] For example, as Figure 14 shown, the placeholder information and the associated target resource use the part of the frequency domain resource outside the RBs used by the PSFCH on the symbol where the PSFCH is located or use at least part of the resources of the PSFCH for transmission.

[0318] 5) There is only one target resource for the power saving information, and this target resource is used for target transmission.

[0319] 5a. The power saving information has an associated target resource and this target resource is used for target transmission (target data and / or target feedback).

[0320] Furthermore, in one implementation, the power saving information can use the 1 st stage SCI format (but may use the PSCCH resource or not use the PSCCH resource, for example, use at least part of the remaining RBs) or directly use at least part of the resources of the PSCCH for transmission, for example, transmitted on the 2nd and 3rd symbols in the symbols available for SL. The associated target resource uses the PSSCH resource. This target resource can be used for target data transmission. Another possible implementation is that the power saving information is transmitted on the remaining RBs, and the associated target resource uses the PSSCH resource. This target resource can be used for target data transmission. Further optionally, the power saving information reuses the SCI format.

[0321] 5b. The power saving information has an associated target resource and this target resource is used for power saving information transmission.

[0322] AsFigure 15 As shown, further, in one implementation, the power saving information can use 1 st stage SCI format (but may use PSCCH resources or not use PSCCH resources, for example, use at least part of the remaining RBs) or directly use at least part of the resources of PSCCH for transmission, for example, transmit on the 2nd and 3rd symbols in the symbols available for SL. The associated target resource uses PSSCH resources. This target resource can be used for power saving information transmission. Another possible implementation is that the power saving information is transmitted on the remaining RBs, and the associated target resource uses PSSCH resources. This target resource can be used for power saving information transmission. Further optionally, the power saving information reuses the SCI format.

[0323] 5c, the power saving information includes placeholder information and a power saving indication command. The placeholder information has a target resource for power saving indication command transmission.

[0324] The power saving information includes placeholder information and a power saving indication command. The power saving information has an associated target resource and this target resource is used for the transmission of the power saving indication command.

[0325] Further, as Figure 16 shown, in one implementation, the placeholder information can use 1 st stage SCI format (but may use PSCCH resources or not use PSCCH resources, for example, use at least part of the remaining RBs) or directly use at least part of the resources of PSCCH for transmission, for example, transmit on the 2nd and 3rd symbols in the symbols available for SL. The associated target resource uses PSSCH resources. This target resource carries the power saving indication command. Another possible implementation is that the placeholder information is transmitted on the remaining RBs, and the associated target resource uses PSSCH resources. This target resource can be used for power saving indication command transmission. Further optionally, the placeholder information reuses the SCI format.

[0326] Further, as Figure 17 shown, in one implementation, the placeholder information can use 1 st stage SCI format (but may use PSCCH resources or not use PSCCH resources, for example, use at least part of the remaining RBs) or directly use at least part of the resources of PSCCH for transmission, for example, transmit on the 2nd and 3rd symbols in the symbols available for SL. The associated target resource uses PSCCH resources. This target resource carries the power saving indication command. Another possible implementation is that the placeholder information is transmitted on the remaining RBs, and the associated target resource uses PSCCH resources. This target resource can be used for power saving indication command transmission. Further optionally, the placeholder information reuses the SCI format.

[0327] A specific example is, such as Figure 18 As shown, placeholder information reuse 1 st SCI format, and transmitted on the PSCCH. The placeholder information indicates a power saving indication command, power saving indication command reuse 1 st SCI format, and transmitted on the PSCCH. Further optionally, the placeholder information and / or the power saving indication command indicate the accompanying PSSCH. In this way, both the placeholder information and the power saving indication command can be demodulated using the PSCCH DMRS.

[0328] 5d, the power saving information has a target resource, which is the placeholder resource.

[0329] The power saving information has an associated target resource and the target resource is the placeholder resource.

[0330] Further, such as Figure 19 As shown, in one implementation, the placeholder information can be used 1 st stage SCI format (but may or may not use PSCCH resources, for example, use at least part of the remaining RBs) or directly use the resources of the PSCCH for transmission, for example, transmitted on the 2nd and 3rd symbols in the symbols available for SL. The associated target resource uses the PSSCH resource. The target resource is not used. Another possible implementation is that the placeholder information is transmitted on the remaining RBs and the associated target resource is not used for transmission. Further optionally, the placeholder information reuses the SCI format.

[0331] 6) The power saving information has multiple target resources.

[0332] The power saving information is associated with a group of target resources. Optionally, the power saving information is associated with 2 target resources; such as Figure 28 As shown, the power saving information is associated with 3 target resources, and the 3 target resources include the resource where it is located; the power saving information is associated with 16 target resources.

[0333] Such as Figure 20 As shown, the placeholder information is associated with 16 target resources. In one implementation, the placeholder information can be used 1 stIt is transmitted in the SCI format (but may or may not use PSCCH resources, for example, using at least part of the remaining RBs), or directly uses at least part of the resources of PSCCH for transmission, for example, transmitted on the second and third symbols in the symbols available for SL. The associated target resources use PSSCH resources. Optionally, the target resources are used to transmit the power saving indication command. Another possible implementation is that the placeholder information is transmitted on the remaining RBs, and the associated target resources use PSSCH resources. Optionally, the target resources are used to transmit the power saving indication command. Further optionally, the placeholder information reuses the SCI format.

[0334] Further assume that the UE ID for transmitting the power saving information is 31, then the first resource is 31 mod 16 = 15, and the target resource 15 is selected to transmit the power saving indication command.

[0335] Further assume that the UE group ID for transmitting the power saving information is 31, then the first resource is 31 mod 16 = 15, and the target resource 15 is selected to transmit the power saving indication command.

[0336] Further assume that the UE ID for transmitting the power saving information is 31, then the first resource is floor(31 / 16) = 1, and the target resource 1 is selected to transmit the power saving indication command.

[0337] Further assume that the UE group ID for transmitting the power saving information is 31, then the first resource is floor(31 / 16) = 1, and the target resource 1 is selected to transmit the power saving indication command.

[0338] Further assume that the UE ID for transmitting the power saving information is 3 and the target UE ID is 10, then the first resource is (3 + 10) mod 16 = 13, and the target resource 13 is selected to transmit the power saving indication command.

[0339] Further assume that the UE ID for transmitting the power saving information is 3 and the group ID of the target UE is 10, then the first resource is (3 + 10) mod 16 = 13, and the target resource 13 is selected to transmit the power saving indication command.

[0340] Further assume that the source ID is 3 and the target desitnation ID is 10, then the first resource is (3 + 10) mod16 = 13, and the target resource 13 is selected to transmit the power saving indication command.

[0341] Further assume that the UE ID for transmitting the power saving information is 3 and the target UE ID is 10, then the first resource is floor((3 + 10) / 16) = 0, and the target resource 0 is selected to transmit the power saving indication command.

[0342] Further assume that the UE ID for sending the power saving information is 3 and the group ID of the target UE is 10. Then the first resource is floor((3 + 10) / 16) = 0, and thus the target resource 0 is selected for sending the power saving indication command.

[0343] Further assume that the source ID is 3 and the target destination ID is 10. Then the first resource is floor((3 + 10) / 16) = 0, and thus the target resource 0 is selected for sending the power saving indication command.

[0344] Further assume that the DRX ID controlled by the power saving information is 3. Then the first resource is (3) mod 16 = 3, and thus the target resource 3 is selected for sending the power saving indication command.

[0345] Floor means rounding down. Besides rounding down, rounding up can also be considered.

[0346] Optionally, before this, the target resource can also be used for target transmission or as a placeholder resource, which will not be elaborated one by one here.

[0347] In this way, multiple UEs share the resources of the placeholder information and send the placeholder information on the placeholder information resources, so that the associated target resources can be known after detecting the placeholder information. The UE determines the first resource for transmission from the associated target resources according to the rules, thus avoiding conflicts between the power saving indication commands of different UEs.

[0348] 7) Some of the target resources associated with multiple power saving information are the same.

[0349] The power saving information is associated with a group of target resources. For example, two power saving information are associated with 16 identical target resources.

[0350] As Figure 21 shown, in one implementation, the placeholder information can use the 1 st stage SCI format (but may use the PSCCH resource or not use the PSCCH resource, for example, use at least part of the remaining RBs) or directly use at least part of the resources of the PSCCH for transmission, for example, transmit on the 2nd and 3rd symbols in the symbols available for SL. The associated target resources use the PSSCH resource. Optionally, the target resource is used for transmitting the power saving indication command. Another possible implementation is that the placeholder information is transmitted on the remaining RBs, and the associated target resources use the PSSCH resource. Optionally, the target resource is used for transmitting the power saving indication command. Further optionally, the placeholder information reuses the SCI format.

[0351] Further assume that the time domain resource ID of the power saving information is 0 and the size of the target resource set is 10. Then the first resource is (0 * 10) mod 16 = 0, and thus target resource 0 is selected to send the power saving indication command.

[0352] Further assume that the time domain resource ID of the power saving information is 1 and the target UE ID is 10. Then the first resource is (1 * 10) mod 16 = 10, and thus target resource 10 is selected to send the power saving indication command.

[0353] Further assume that the time domain resource ID of the power saving information is 0 and the size of the target resource set is 10. Then the first resource is (0 * 10) / 16 = 0, and thus target resource 0 is selected to send the power saving indication command.

[0354] Further assume that the time domain resource ID of the power saving information is 1 and the target UE ID is 10. Then the first resource is floor((1 * 10) / 16) = 0, and thus target resource 0 is selected to send the power saving indication command.

[0355] Floor means rounding down. Besides rounding down, rounding up can also be considered.

[0356] Optionally, the target resource can also be used for target transmission or as a placeholder resource, which will not be elaborated one by one.

[0357] In this way, multiple UEs share the resources of the placeholder information and send the placeholder information on the placeholder information resources, so that the associated target resources can be known after detecting the placeholder information. The UE determines the first resource for transmission from the associated target resources according to the rules, thus avoiding conflicts between the power saving indication commands of different UEs.

[0358] In addition, in this application, optionally, the method further includes:

[0359] Sending power saving information.

[0360] As can be seen from the above, the first user equipment can use the first resource to transmit the power saving information. At this time, preferably, the first resource indicated by the power saving information, that is, the indicated part of the target resources indicated by the power saving information.

[0361] Optionally, the first user equipment is the target item sender, and when the power saving information indicates non - active or dormant, the sending of the target item is stopped;

[0362] Wherein, the resources of the power saving information and / or the target resources associated with the power saving information are dedicated resources, or the resources of the power saving information and / or the target resources associated with the power saving information are common resources.

[0363] Correspondingly, the second user equipment that receives the power saving information is the receiving end of the target item:

[0364] When the power saving information indicates inactivity or sleep, and the resources of the power saving information and / or the target resources associated with the power saving information are dedicated resources, the second user equipment performs inactivity or sleep and stops receiving at least one of the target items. When the resources of the power saving information and / or the target resources associated with the power saving information are common resources, the second user equipment performs inactivity or sleep and stops receiving at least one of the target items when it receives power saving information indicating inactivity or sleep sent by at least some of the user equipment in the target user equipment group; or, when it receives power saving information indicating inactivity or sleep sent by at least some of the user equipment in the target user equipment group, and the overlapping part of the inactivity or sleep times corresponding to the received power saving information is greater than a second threshold, it performs inactivity or sleep and stops receiving at least one of the target items.

[0365] In this way, the first user equipment UE1 is the TX UE, the second user equipment UE2 is the RX UE, and the RX UE receives the power saving information. Here, the power saving information indicates the power saving mechanism of UE2. Specifically, if the power saving information indicates sleep:

[0366] When the resources of the power saving information and / or the target resources associated with it are dedicated resources, the TX UE stops sending the target item to the RX UE, and the RX UE performs sleep and stops receiving at least one of the target items sent by the TX UE; when the resources of the power saving information and / or the target resources associated with it are common resources, the TX UE stops sending the target item to the RX UE, but only when at least some of the UEs in the target UE group have all sent power saving information indicating sleep, or the overlapping part of the sleep times after sending the power saving information is greater than a certain threshold (the second threshold), the RX UE performs sleep and stops receiving at least one of the target items sent by all the TX UEs in the target UE group. Specifically, at least some of the UEs in the target UE group are the TX UEs that have sent power saving information indicating sleep within a time window.

[0367] At least some of the UEs in the target UE group are all the TX UEs that have sent sleep power-saving information within the target UE group. For example, if the target UE group includes 10 UEs, but only 5 TX UEs, and all of them have sent sleep power-saving information, then when UE2 receives the sleep power-saving information sent by these 5 TX UEs, it performs at least one of sleeping and stopping receiving the target item sent by the TX UEs in the target UE group; of course, if only 2 TX UEs in the target UE group have sent sleep power-saving information, rather than all TX UEs having sent sleep power-saving information, then when UE2 receives the sleep power-saving information sent by these 2 TX UEs, it does not sleep and still has to receive the target item sent by the 5 TX UEs in the target UE group.

[0368] Optionally, when the first user equipment is the sender of the target item and the power-saving information indicates activation or wake-up, the target item is sent.

[0369] Wherein, the resource of the power-saving information and / or the target resource associated with the power-saving information is a resource dedicated to the user equipment, or the resource of the power-saving information and / or the target resource associated with the power-saving information is a common resource.

[0370] Correspondingly, the second user equipment that receives the power-saving information is the receiver of the target item:

[0371] When the power-saving information indicates activation or wake-up, and the resource of the power-saving information and / or the target resource associated with the power-saving information is a dedicated resource, the second user equipment performs at least one of activation or wake-up and receiving the target item. When the resource of the power-saving information and / or the target resource associated with the power-saving information is a common resource, the second user equipment performs at least one of activation or wake-up and receiving the target item when it receives the power-saving information indicating activation or wake-up sent by any one or at least one user equipment in the target user equipment group.

[0372] Specifically, if the power-saving information indicates activation:

[0373] When the resource of the power-saving information and / or its associated target resource is a dedicated resource, the TX UE sends the target item to the RX UE, and the RX UE performs at least one of activation and receiving the target item; when the resource of the power-saving information and / or its associated target resource is a common resource, the TX UE sends the target item to the RX UE, and the RX UE performs at least one of activation and receiving the target item only when it receives the power-saving information indicating activation sent by any one or at least one user equipment in the target UE group.

[0374] Optionally, when the first user equipment is a target item receiver and the power saving information indicates inactivity or sleep, receiving of the target item is stopped;

[0375] Wherein, the resource of the power saving information and / or the target resource associated with the power saving information is a dedicated resource, or the resource of the power saving information and / or the target resource associated with the power saving information is a common resource.

[0376] Correspondingly, the second user equipment receiving the power saving information is the target item sender:

[0377] When the power saving information indicates inactivity or sleep and the resource of the power saving information and / or the target resource associated with the power saving information is a dedicated resource, the second user equipment performs at least one of inactivity or sleep and stops sending the target item. When the resource of the power saving information and / or the target resource associated with the power saving information is a common resource, the second user equipment performs at least one of inactivity or sleep and stops sending the target item when receiving power saving information indicating inactivity or sleep sent by at least some of the user equipment in the target user equipment group; or, when receiving power saving information indicating inactivity or sleep sent by at least some of the user equipment in the target user equipment group and the overlapping part of the inactivity or sleep time corresponding to the received power saving information is greater than a first threshold, performs at least one of inactivity or sleep and stops sending the target item.

[0378] In this way, the first user equipment UE1 is the RX UE, the second user equipment UE2 is the TX UE, and the RX UE receives the power saving information. Specifically, if the power saving information indicates sleep:

[0379] When the resource of the power saving information and / or the target resource associated with it is a dedicated resource, the TX UE performs sleep and stops sending at least one of the target items to the RX UE, and the RX UE stops receiving the target items sent by the TX UE; when the resource of the power saving information and / or the target resource associated with it is a common resource, the RX UE stops receiving the target items sent by the TX UE, but only when at least some of the UEs in the target UE group have all sent power saving information indicating sleep, or the overlapping part of the sleep time after sending the power saving information is greater than a certain threshold (the first threshold), does the TX UE perform sleep and stop sending at least one of the target items to all the TX UEs in the target UE group. Specifically, at least some of the UEs in the target UE group send power saving information indicating sleep within a time window.

[0380] At least some of the UEs within the target UE group are all the RX UEs that have sent power-saving information for hibernation within the target UE group. For example, if the target UE group includes 10 UEs, but only 5 RX UEs, and all of them have sent power-saving information for hibernation, then UE2 performs hibernation and stops sending at least one of the target items sent by the 5 RX UEs within the target UE group when it receives the power-saving information for hibernation sent by the 5 RX UEs; of course, if only 2 RX UEs out of the 10 UEs have sent power-saving information for hibernation, and UE2 receives the power-saving information for hibernation sent by the 2 RX UEs, it does not hibernate and still has to send the target items to the 5 RX UEs within the target UE group.

[0381] Optionally, when the first user equipment is the target item receiver and the power-saving information indicates activation or wake-up, it receives the target item;

[0382] Wherein, the resource of the power-saving information and / or the target resource associated with the power-saving information is a dedicated resource, or the resource of the power-saving information and / or the target resource associated with the power-saving information is a common resource.

[0383] Correspondingly, the second user equipment that receives the power-saving information is the target item sender:

[0384] When the power-saving information indicates activation or wake-up, when the resource of the power-saving information and / or the target resource associated with the power-saving information is a dedicated resource, the second user equipment performs activation or wake-up and sends at least one of the target items. When the resource of the power-saving information and / or the target resource associated with the power-saving information is a common resource, the second user equipment performs activation or wake-up and sends at least one of the target items when it receives the power-saving information indicating activation or wake-up sent by any one or at least one user equipment within the target user equipment group.

[0385] In this way, the first user equipment UE1 is the RX UE, the second user equipment UE2 is the TX UE, and the RX UE receives the power-saving information. Specifically, if the power-saving information indicates activation:

[0386] When the resource of the power-saving information and / or its associated target resource is a dedicated resource, the RX UE receives the target item, and the TX UE performs activation and sends at least one of the target items to the RX UE; when the resource of the power-saving information and / or its associated target resource is a common resource, the RX UE receives the target item sent by the TX UE, but only when at least one UE within the target UE group has sent the power-saving information indicating activation, the TX UE performs activation and sends at least one of the target items to all the TX UEs within the target UE group.

[0387] Among them, the target UE group is a group including the TX UE and / or the RX UE to which at least one of UE1 and UE2 belongs. Specifically, in one possible implementation, the target UE group can be constituted based on at least one of the UEs located in the preset geographical location 1, the UEs not located in the preset geographical location 2, the UEs within the preset communication distance 1, the UEs not within the communication distance 2, etc. For example, the UEs all located within zone#0 can be regarded as the target UE group. For example, the UEs within their own communication distance can be regarded as the target UE group.

[0388] In this embodiment, the target item can be at least one of data, control, and RS. The dedicated resource can be understood as the resource that can be used only by the transceiver of the power saving information, and the common resource can be understood as the resource that can be used by the transceiver of the power saving information and the user equipment other than the transceiver of the power saving information.

[0389] Such as Figure 22 As shown, a power saving processing method according to an embodiment of the present application is executed by a second user equipment, and includes:

[0390] Step 2201, receiving power saving information, where the power saving information is associated with a target resource, and the target resource is used to determine a first resource; wherein, the first resource includes at least one of the following:

[0391] The resource of the power saving information;

[0392] The resource of the target transmission;

[0393] The vacant resource.

[0394] Here, the power saving information is used to indicate that the first target user equipment is activated or awakened or deactivated or put to sleep. The power saving information has a target resource associated therewith, and the target resource is used to determine the first resource. Therefore, by receiving the power saving information, the user equipment at both ends of the communication keeps consistent understanding of the resource, so as to achieve coordination and power saving.

[0395] In this embodiment, the power saving information includes at least one of the following:

[0396] Placeholder information;

[0397] Power saving indication command.

[0398] Optionally, when the second user equipment is the sender of the target item, the power saving information indicates deactivation or sleep, and the resource of the power saving information and / or the target resource associated with the power saving information is a dedicated resource, at least one of the following is executed:

[0399] Deactivate or sleep;

[0400] Stop sending the target item.

[0401] Optionally, when the second user equipment is a target item sender, the power saving information indicates deactivation or hibernation, and the resource of the power saving information and / or the target resource associated with the power saving information is a common resource,

[0402] When receiving power saving information indicating deactivation or hibernation sent by at least some user equipments within a target user equipment group, perform at least one of the following: deactivate or hibernate; stop sending the target item; or, when receiving power saving information indicating deactivation or hibernation sent by at least some user equipments within a target user equipment group, and the overlapping part of the deactivation or hibernation times corresponding to the received power saving information is greater than a first threshold, perform at least one of the following: deactivate or hibernate; stop sending the target item;

[0403] Optionally, when the second user equipment is a target item sender, the power saving information indicates activation or wake-up, and the resource of the power saving information and / or the target resource associated with the power saving information is a dedicated resource, perform at least one of the following: activate or wake up; send the target item.

[0404] Optionally, when the second user equipment is a target item sender, the power saving information indicates activation or wake-up, and the resource of the power saving information and / or the target resource associated with the power saving information is a common resource, when receiving power saving information indicating activation or wake-up sent by any one or at least one user equipment within a target user equipment group, perform at least one of the following: activate or wake up; send the target item.

[0405] Optionally, when the second user equipment is a target item receiver, the power saving information indicates deactivation or hibernation, and the resource of the power saving information and / or the target resource associated with the power saving information is a dedicated resource, perform at least one of the following: deactivate or hibernate; stop receiving the target item.

[0406] Optionally, when the second user equipment is a target item receiver, the power saving information indicates deactivation or hibernation, and the resource of the power saving information and / or the target resource associated with the power saving information is a common resource,
