Description

Methods executed by user equipment and user equipment Technical Field

[0001] This invention relates to the field of wireless communication technology, and more specifically, to a method for network power saving performed by a user equipment and a corresponding user equipment. Background Technology

[0002] Network energy conservation helps reduce environmental impact and save operator costs. Networks typically need to periodically transmit Service Buffers (SSBs) to enable UEs to synchronize with cells and measure beam quality and cell quality. Periodic SSB transmission consumes power, especially under low system load, resulting in wasted network power. For these reasons, the 3rd Generation Partnership Project (3GPP) approved the NES enhancement work item for version 19 at the RAN plenary meeting, the details of which can be found in non-patent literature: RP-234065 WID: Enhancements of network energy savings for NR. This work item includes the ability for the network to transmit SSBs to cells on demand or extend the SSB transmission period under low system load, dynamically triggering SSB transmission or using shorter SSB transmission periods based on system load changes and UE service activity, thereby achieving network energy conservation goals. Summary of the Invention

[0003] In order to solve the above problems, the present invention aims to provide a method and user equipment for network energy saving performed by user equipment that can correctly determine the on-demand SSB status and configuration.

[0004] According to one aspect of the present invention, a method performed by a user equipment is provided, comprising: receiving an RRC message sent by a network, the RRC message including configuration information of an on-demand SSB, the configuration information of the on-demand SSB including an on-demand SSB status indication, and determining, based on the on-demand SSB status indication, whether the status of the on-demand SSB is active or deactivated; receiving a first MAC control unit MAC CE sent by the network, and determining, based on the first MAC CE indication and the status of the on-demand SSB before receiving the first MAC CE, whether to update the on-demand SSB, wherein the process of determining whether to update the on-demand SSB includes: updating the on-demand SSB if the first MAC CE indicates that the on-demand SSB is active, and if the on-demand SSB was active before receiving the first MAC CE.

[0005] In the above-described method performed by the user equipment, preferably, a second MAC control unit (MAC CE) sent by the network is received, and the on-demand SSB is determined whether to update based on the indication of the second MAC CE and the status of the on-demand SSB before receiving the second MAC CE. The process of determining whether to update the on-demand SSB includes: updating the on-demand SSB if the second MAC CE indicates that the on-demand SSB should be updated, and if the on-demand SSB was active before receiving the second MAC CE.

[0006] In the above-described method performed by the user equipment, preferably, a second MAC control unit (MAC CE) sent by the network is received, and the on-demand SSB is determined whether to maintain the on-demand SSB based on the indication of the second MAC CE and the state of the on-demand SSB before receiving the second MAC CE. The process of determining whether to maintain the on-demand SSB includes: maintaining the on-demand SSB if the second MAC CE indicates that the on-demand SSB should be maintained, and if the on-demand SSB was active before receiving the second MAC CE.

[0007] In the above-described method executed by the user equipment, preferably, the format of the second MAC CE includes fields Ci, Mi, OD-SSB configuration index, and R. The field Ci indicates the activation / deactivation status of the on-demand SSB of the secondary cell configured with on-demand SSB, the field Mi indicates the update status of the on-demand SSB of the secondary cell configured with on-demand SSB, the field OD-SSB configuration index indicates the on-demand SSB configuration index, and the field R is a reserved bit.

[0008] In the above-described method performed by the user equipment, preferably, the field Mi is set to 1 to indicate that the on-demand SSB of the secondary cell with serving cell index i is updated, and the field Mi is set to 0 to indicate that the on-demand SSB of the secondary cell with serving cell index i is initially activated; if the field Ci is set to 0, the field Mi is ignored, or the field Mi does not exist.

[0009] In the above-described method performed by the user equipment, preferably, the format of the second MAC CE includes a field Ci, an on-demand SSB configuration index (OD-SSB), and a field R. The field Ci indicates the activation / deactivation / update / maintenance status of the on-demand SSB of the secondary cell configured with on-demand SSB, the field OD-SSB configuration index indicates the on-demand SSB configuration index, and the field R is a reserved bit.

[0010] In the above-described method performed by the user equipment, preferably, setting the field Ci to 0 indicates that the on-demand SSB of the secondary cell with serving cell index i is deactivated, setting the field Ci to 1 indicates that the on-demand SSB of the secondary cell with serving cell index i is activated, setting the field Ci to 2 indicates that the on-demand SSB of the secondary cell with serving cell index i is updated, and setting the field Ci to 3 indicates that the on-demand SSB of the secondary cell with serving cell index i is maintained.

[0011] According to another aspect of the present invention, a method executed by a user equipment is provided, comprising: a processor; and a memory storing instructions, wherein the instructions, when executed by the processor, perform the method described above.

[0012] Effects of the invention: According to the user equipment method and user equipment disclosed herein, the UE can correctly determine the state of the on-demand SSB, apply the on-demand SSB configuration, and avoid affecting the UE service performance. Attached Figure Description

There may be a relationship of inclusion between the two terms, and they do not necessarily refer to completely different content.

[0088] The related technologies of the present invention are described below.

[0089] Generally, on a SCell, the network continuously transmits SSBs periodically; such SSBs are also called always-on SSBs. Even for deactivated SCells, the network still periodically transmits SSBs. The UE can use SSBs for cell time-frequency synchronization, beam quality measurement, and cell quality measurement. To save network energy, the network can lengthen the SSB transmission period or stop transmitting SSBs altogether, but this may affect the UE's time-frequency synchronization and measurement. To address this issue, OD-SSB is introduced. Based on system load changes and UE service conditions, the network activates OD-SSB as needed; that is, the network switches from not transmitting SSBs to transmitting OD-SSBs, or from transmitting always-on SSBs to simultaneously transmitting both always-on SSBs and OD-SSBs (usually the OD-SSB transmission period is shorter), or dynamically adjusts the OD-SSB period.

[0090] Depending on whether an always-on SSB exists on the SCell, there are two types of SCells: Type 1 SCell, which does not have an always-on SSB; and Type 2 SCell, which has an always-on SSB.

[0091] A cell that is configured with OD-SSB, or that supports OD-SSB, can be called an OD-SSB cell. If the cell is an SCell, then it can be called an OD-SSB SCell.

[0092] This invention discusses how a UE determines the activation, deactivation, and update of an OD-SSB, as well as the format of the MAC CE used for OD-SSB activation, deactivation, and update, so that the UE can correctly determine the state of the OD-SSB while saving network energy, apply on-demand SSB configuration, and avoid affecting the performance of UE services.

[0093] Example 1

[0094] Figure 1 is a schematic diagram of method one executed by the UE according to one or more embodiments. The UE can execute one or more steps in Figure 1. Figure 1 includes steps S101 to S102.

[0095] Optionally, in step S101, the UE receives an RRC message sent by the network. Optionally, the RRC message is system information and / or RRC-specific signaling (e.g., an RRC reconfiguration message). Optionally, the RRC message includes OD-SSB configuration.

[0096] Optionally, the OD-SSB configuration includes at least one of the following:

[0097] -OD-SSB configuration index (or OD-SSB configuration identifier);

[0098] -OD-SSB status indication (or OD-SSB initial status indication);

[0099] - Number of OD-SSB bursts;

[0100] -OD-SSB Physical Cell Identifier.

[0101] Optionally, the OD-SSB configuration is included in the cell configuration to indicate the OD-SSB configuration of the cell.

[0102] Optionally, the OD-SSB status indicator (or OD-SSB initial status indicator) is used to indicate the status (or initial state) of the OD-SSB. Optionally, the OD-SSB status indicator (or OD-SSB initial status indicator) exists when the OD-SSB configuration is initially configured or established, and / or when the OD-SSB status changes; otherwise, the OD-SSB status indicator (or OD-SSB initial status indicator) does not exist. Optionally, when the OD-SSB is configured, the OD-SSB is deactivated until the OD-SSB status indicator (or OD-SSB initial status indicator) is set to active. Optionally, if the cell is a Type 2 SCell, and / or if the cell is a Type 1 SCell and the cell (i.e., Type 1 SCell) is deactivated, the OD-SSB status indicator (or OD-SSB initial status indicator) can be set to deactivated; in other words, if the cell is a Type 1 SCell and the cell (i.e., Type 1 SCell) is active, the OD-SSB status indicator (or OD-SSB initial status indicator) cannot be set to deactivated.

[0103] Optionally, an OD-SSB configuration index (or OD-SSB configuration identifier) ​​is used to index or identify an OD-SSB configuration.

[0104] Optionally, the number of OD-SSB bursts indicates the number of OD-SSB bursts to be transmitted after the OD-SSB is activated (or after the OD-SSB is instructed to transmit). Optionally, after transmitting the OD-SSB bursts indicated by the number of OD-SSB bursts, the UE considers the OD-SSB to be deactivated, or stops the OD-SSB transmission.

[0105] Optionally, the OD-SSB physical cell identifier is used to indicate the physical cell identifier of a Type I SCell, i.e., the physical cell identifier of a cell that does not have an always-on SSB.

[0106] Optionally, Type 1 SCell refers to a SCell without always-on SSB, and Type 2 SCell refers to a SCell with always-on SSB.

[0107] The UE's behavior when the OD-SSB status indication (or OD-SSB initial status indication) takes different values ​​is described below:

[0108] Optionally, if the OD-SSB status indication (or OD-SSB initial status indication) is included in the RRC message, or if the OD-SSB status indication (or OD-SSB initial status indication) is set to active, it indicates that the OD-SSB is active (or the OD-SSB is being transmitted). The UE considers the OD-SSB to be active (or the OD-SSB is indicated to be transmitted), and the UE performs at least one of the following operations:

[0109] - Activate the OD-SSB (of the cell);

[0110] - Instructs the lower layer to activate the OD-SSB of the cell.

[0111] Optionally, if the OD-SSB status indication (or OD-SSB initial status indication) is not included in the RRC message, or if the OD-SSB status indication (or OD-SSB initial status indication) is set to deactivated, it indicates that the OD-SSB is in a deactivated state. The UE considers the OD-SSB to be deactivated, and the UE performs at least one of the following operations:

[0112] - Deactivate the OD-SSB (of the cell);

[0113] - Instruct the lower layer to deactivate the (cell's) OD-SSB.

[0114] Alternatively, if the OD-SSB status indication (or OD-SSB initial status indication) is not included in the RRC message, it indicates that the OD-SSB status remains unchanged, the UE considers the OD-SSB status unchanged, and the UE performs at least one of the following operations:

[0115] - Update and / or reapply the OD-SSB (configuration) of the cell;

[0116] - If the OD-SSB is active, update and / or reapply the (cell's) OD-SSB (configuration);

[0117] - Instructs lower layers to update and / or reapply the OD-SSB (configuration) of the cell.

[0118] Optionally, the cell refers to the cell in which the UE receives the RRC message, or the cell is an SCell or a serving cell.

[0119] Optionally, in step S102, the UE receives the first MAC CE sent by the network. Optionally, the first MAC CE is an OD-SSB activation / deactivation MAC CE. This name is only an example, and the first MAC CE can also be any other MAC CE used to activate / deactivate OD-SSB.

[0120] Compared to the OD-SSB status indication (or OD-SSB initial status indication) in step S101, the first MAC CE is to more dynamically activate, deactivate, and update the OD-SSB after it is configured.

[0121] Based on the current state of the first MAC CE and OD-SSB, the UE performs corresponding actions for different situations.

[0154] - If the SCell is active and the SCell is a type 1 SCell, ignore the first MAC CE.

[0155] Alternatively, if at least one of the above conditions is met, except that the SCell is a type-1 SCell and the SCell is deactivated, at least one of the above operations is performed.

[0156] Optionally, the SCell refers to the cell in which the UE receives the first MAC CE, or the SCell may be the serving cell (or replaced by the serving cell).

The names here are just examples, and the second MAC CE can also be any other MAC CE used to activate, deactivate, update, or maintain the OD-SSB.

[0161] Optionally, (for each SCell configured with OD-SSB) the UE or the UE's MAC entity, when the second MAC CE is received and indicates activation or deactivation of the (SCell's) OD-SSB, the UE's judgment and operation are the same as those in step S102 when the first MAC CE is received and indicates activation or deactivation of the (SCell's) OD-SSB, and will not be repeated here.

[0181] Example 3

[0182] According to Method 2, the format of the second MAC CE is at least one of the following formats.

[0183] In this article, for illustrative purposes, the fields in the second MAC CE are set to 0 or 1 in different cases. Correspondingly, they can also be set to 1 or 0 in the corresponding cases, or set to "yes" or "no". No restrictions are imposed here.

[0184] Format 1:

[0185] In this format, optionally, the fields Ci, Mi, OD-SSB configuration index, and R exist.

[0186] Optionally, the Ci field indicates the OD-SSB activation / deactivation status of the SCell configured with OD-SSB, where the SCell refers to the SCell with a serving cell index (ServCellIndex) of i. Here, i corresponds to the index (ServCellIndex) of the serving cell or SCell; for example, C1 corresponds to the OD-SSB activation / deactivation status of the SCell with a ServCellIndex of 1.

[0187] Optionally, setting the Ci field to 1 indicates that the OD-SSB of the SCell with ServCellIndex i is activated, and setting the Ci field to 0 indicates that the OD-SSB of the SCell with ServCellIndex i is deactivated.

[0188] Optionally, the Mi field indicates the OD-SSB update status of the SCell configured with OD-SSB, where the SCell refers to the SCell with ServCellIndex i. Here, i corresponds to the index (ServCellIndex) of the serving cell or SCell; for example, M1 corresponds to the OD-SSB update status of the SCell with ServCellIndex 1.

[0189] Optionally, if Ci is set to 0, i.e., the Ci field indicates that the OD-SSB of the SCell with ServCellIndex i is deactivated, Mi is ignored, or the Mi field does not exist and is replaced by the reserved bits of the R field.

[0190] Optionally, setting the Mi field to 1 indicates that the OD-SSB of the SCell with ServCellIndex i is updated, and setting the Mi field to 0 indicates that the OD-SSB of the SCell with ServCellIndex i is initially activated. Alternatively, setting the Mi field to 0 indicates that the OD-SSB of the SCell with ServCellIndex i is updated, and setting the Mi field to 1 indicates that the OD-SSB of the SCell with ServCellIndex i is initially activated.

[0191] Optionally, the OD-SSB configuration index field indicates the OD-SSB configuration index.

[0192] R: This field is reserved bits and is usually set to 0.

[0193] The following table shows the possible distribution of these fields, with the one-byte Ci field as an example:

[0194] Table 1
