Description

Technical Field

[0001] This application belongs to the field of wireless communication technology, specifically relating to a method, apparatus, terminal, and network-side equipment for determining cell scheduling mode. Background Technology

[0002] The 5G New Radio (NR) system supports Carrier Aggregation (CA), which allows configuration and activation of multiple component carriers (CCs) or cells for User Equipment (UE), and supports cross-carrier scheduling under CA. Furthermore, NR also supports multiple Transmission and Reception Panel (M-TRP) scenarios, where the UE can be scheduled and transmit / receive data by multiple TRPs.

[0003] In current NR systems, both the primary cell (Pcell) and secondary cell (Scell) can be configured for self-scheduling. Only Scells can perform cross-carrier scheduling through Pcells or other Scells; Pcells can only perform self-scheduling. When an Scell ​​is configured for cross-carrier scheduling, the serving cell ID for scheduling that cell needs to be configured, along with the Carrier Indicator Field (CIF) value for scheduling within that serving cell.

[0004] Therefore, in existing NR systems, a cell can only be scheduled by one scheduling cell (i.e., it can only be self-scheduled or scheduled by another cell), and currently, a PCcell can only be scheduled by itself. To enhance control channel coverage, PCcells are generally deployed on low-frequency carriers. However, low-frequency carriers have insufficient bandwidth and have already been extensively deployed in other series (e.g., LTE).

[0005] Therefore, the limited control channel capacity of Pcells can be addressed by configuring high-frequency carriers as Scells and scheduling Pcells through Scells, thereby reducing the control channel PDCCH overhead. However, the target does not yet provide a specific scheme for determining the cell scheduling method when scheduling Pcells through Scells. Summary of the Invention

[0115] Among the above possible implementations, a specific RNTI includes, but is not limited to, at least one of the following: Cell RNTI (C-RNTI), Configured Scheduling RNTI (CS-RNTI), and MCS-C-RNTI.

[0116] In the above possible implementations, the search space for scheduling the second cell across carriers in the first cell can be a search space that meets certain conditions, such as a search space with the same identifier as the search space in the activated BWP of the first cell.

[0117] For example, if Pcell is configured to be scheduled by Scell ​​1 and Pcell is configured with CSS, then if the first cell is in the first target state, it is determined that Pcell is scheduled across carriers by SS that meets the conditions on Scell ​​1, and self-scheduling with specific RNTI scrambling (e.g., C-RNTI, CS-RNTI, MCS-C-RNTI) is not used (if the communication device is a terminal, the terminal may not listen to the self-scheduling with RNTI scrambling on the second cell), that is, the configured CSS and / or USS group 1 (if configured) do not perform the scheduling function of specific RNTI; or, it is determined that Pcell is scheduled across carriers by SS that meets the conditions on Scell ​​1, and self-scheduling with CSS scrambling with specific RNTI is used, that is, the configured USS group 1 (if configured) does not perform the scheduling function of specific RNTI, and the terminal may not listen to the self-scheduling with RNTI scrambling with CSS on the second cell.

[0118] In another possible implementation, determining the scheduling method of the second cell based on the scheduling configuration information and the activity status may include:

[0119] If the first cell is in the second target state, it is determined that the first cell cannot schedule the second cell, and the CSS configured on the second cell and / or some or all USS in the first terminal-specific search space group are scheduled with specific RNTI scrambling; or

[0120] It is determined that the first cell cannot schedule the second cell, and CSS self-scheduling with specific RNT scrambling is used on the second cell, and the CSS configured on the second cell and some or all USS in the first terminal-specific search space group are scheduled with specific RNTI scrambling.

[0121] The second target state includes at least one of the following: inactive state; dormant state; or an active BWP with no search space for the second cell to be scheduled.

[0122] Through the above possible implementation methods, the scheduling method of the second cell can be determined when the first cell is in an inactive state, a dormant state, or when there is no search space for scheduling the second cell on the activated BWP.

[0123] For example, if Pcell is configured to be scheduled by Scell ​​1 and Pcell is configured with CSS, then if the first cell is in the second target state, then it is determined that:

[0124] Scell ​​1 cannot perform Pcell scheduling, but uses self-scheduling with scrambling of specific RNTIs (e.g., C-RNTI, CS-RNTI, MCS-C-RNTI). This means that the configured CSS and / or some or all of USS group 1 (if configured) perform specific RNTI scheduling. The terminal can listen to the RNTI-scrambled self-scheduling on the second cell; or

[0125] Scell ​​1 cannot perform Pcell scheduling. It uses CSS self-scheduling with specific RNTI scrambling and simultaneously uses USS group 1 (if configured) self-scheduling with specific RNTI scrambling. That is, some or all of USS group 1 (if configured) performs specific RNTI scheduling. The terminal does not need to listen to CSS self-scheduling with RNTI scrambling on the second cell.

[0126] In the above possible implementations, the partial USS is a search space within the first terminal-specific search space group, and the identifier of the partial USS is the same as the identifier of the target search space, which is the search space within the currently active BWP of the first cell. In other words, the partial USS is a search space with the same identifier as the search space in the first USS group and the currently active BWP.

[0127] For example, suppose the terminal's PCel1 configuration is scheduled by Scell1, and CSS#1, fully configured USS#2 and USS#3, and partially configured USS#4 and USS#5 (only SS ID and aggregation level are configured) are also configured on BWP#1. Only the USS of Scell1 corresponding to the partially configured USS ID can schedule PCel1.

[0128] USS#4 is configured on BWP#2 of Scell ​​1, and USS#2 is configured on BWP#2. At this time, BWP#2 of Scell ​​1 is the active BWP. Therefore, USS#2 and #3 of Pcell do not perform self-scheduling.

[0129] When the UE receives a MAC CE to deactivate in Scell ​​1, or when the sCellDeactivationTimer times out, or when it receives a DCI instruction that Scell ​​1 has entered the dormancy state, USS#2 and USS#3 will enable the self-scheduling function.

[0130] Alternatively, when the UE receives a DCI in Scell ​​1 switching from BWP#2 to BWP#3, and the inactivity timer of BWP#2 times out and switches to BWP#3 when BWP switching takes effect, USS#2 and USS#3 enable self-scheduling function.

[0131] Optionally, CSS#1 can always allow self-scheduling, or, like USS#2 and USS#3, enable and disable the self-scheduling function.

[0132] In another possible implementation, determining the scheduling method of the second cell based on the scheduling configuration information and the activity status may include:

[0133] If the first cell is in the third target state, then at the first target moment after receiving the first target information, the scheduling function of specific RNTI scrambling of the CSS and / or the first terminal-specific search space group configured on the second cell is activated.

[0134] The third target state includes at least one of the following: from an active state to an inactive state; from a non-dormant state to a dormant state; or from the first BWP to the second BWP.

[0135] In the above possible implementations, the first target information includes, but is not limited to, any one of the following: deactivation signaling of the first cell, control information indicating a transition from a non-dormant state to a dormant state, and control information indicating a switch from the first BWP to the second BWP.

[0136] For example, if a Pcell is configured to be scheduled by Scell ​​1 and the Pcell is configured with CSS, then if the first cell is in the second target state, the terminal can determine that: at the first target time after receiving a deactivation signaling from Scell ​​1, or a DCI indicating a transition from non-dormancy to dormancy state, or a DCI indicating BWP switching, the configured CSS and / or USS group 1 (if configured) will be enabled to perform specific RNTI scheduling functions.

[0137] In one possible implementation, the first target time includes any of the following: the effective time of the event indicated by the first target information; or a predetermined time after the effective time of the event indicated by the first target information; or the time of Radio Resource Control (RRC) signaling configuration. The predetermined time can be configured on the network side or predefined, and is not limited in this embodiment.

[0138] For example, the first target time is the time when Scel l is deactivated, the time when Scel l enters the dormancy state, or the time when BWP switching takes effect; or the first target time is a certain time after Scel l is deactivated, a certain time after Scel l enters the dormancy state, or a certain time after the time when BWP switching takes effect.

[0139] Alternatively, in one possible implementation, determining the scheduling method of the second cell based on the scheduling configuration information and the activity status may include:

[0140] If the first cell is in the third target state, then at the second target time after the target timer expires, the scheduling function of specific RNTI scrambling of the CSS and / or the first terminal exclusive search space group configured on the second cell is enabled.

[0141] The third target state includes at least one of the following: from an active state to an inactive state; from a non-dormant state to a dormant state; or from the first BWP to the second BWP.

[0142] Optionally, in the above possible implementations, the target timer may include: a cell deactivation timer or a BWP deactivation timer.

[0143] In the above possible implementations, the second target time may optionally include any of the following:

[0144] The effective time of the event indicated by the target timer timeout;

[0145] The target timer timeout indicates the effective time of the event after a predetermined time;

[0146] The timing of RRC signaling configuration.

[0147] For example, assuming Pcell is configured to be scheduled by Scell ​​1 and Pcell has CSS configured, when the cell deactivation timer (sCellDeactivationTimer) of Scell ​​1 expires, Scell ​​1 is triggered to go from active to inactive; or when the BWP deactivation timer (bwpInactivityTimer) of the current BWP (second BWP) of Scell ​​1 expires, Scell ​​1 BWP handover is triggered. At a specific moment after Scell ​​1 goes from active to inactive or after Scell ​​1 BWP handover, the configured CSS and / or USS group 1 (if configured) are enabled to perform specific RNTI scheduling functions.

[0148] This specific time is either the effective time of Scell ​​deactivation after the timer expires, or the effective time of BWP switching; or

[0149] This specific time is the effective time for Scell ​​deactivation after the timer expires, or a certain time after the effective time of BWP switching (which can be configured on the network side or predefined); or

[0150] This specific moment is the moment when RRC signaling is configured.

[0151] In one possible implementation, determining the scheduling method of the second cell based on the scheduling configuration information and the activity status may include:

[0152] If the first cell is in the fourth target state, then at the third target time after receiving the second target information, the scheduling function of the CSS and / or the first terminal-specific search space group configured on the second cell for specific RNTI scrambling is turned off; wherein, if the communication device is a network-side device, receiving the second target information means sending the second target information, and if the communication device is a terminal, receiving the second target information means receiving the second target information.

[0153] The fourth target state includes at least one of the following: transitioning from a deactivated state to an activated state; transitioning from a dormant state to a non-dormant state; or switching from the second BWP to the first BWP.

[0154] In the above possible implementations, the third target time includes any of the following:

[0155] The effective time of the event indicated by the second target information;

[0156] After the predetermined time following the effective time of the event indicated by the second target information;

[0157] The timing of RRC signaling configuration.

[0158] In the above possible implementations, the second target information includes any one of the following:

[0159] Activate the activation signaling of the first cell;

[0160] Control information indicating the transition of the first cell from a dormant state to a non-dormant state;

[0161] Control information instructing the first cell to switch from the second BWP to the first BWP.

[0162] For example, if a Pcell is configured to be scheduled by Scell ​​1 and has CSS configured, when Scell ​​1 is in a state of transition from inactive to active, from dormancy to non-dormancy, and / or BWP switching (from a BWP with no schedulable Pcell to a BWP with a schedulable Pcell), the UE will disable the configured CSS and / or USS group 1 (if configured) for specific RNTI scheduling functions at a specific time after receiving an activation MAC CE from Scell ​​1, or a DCI indicating transition from dormancy to non-dormancy, or a DCI indicating BWP switching (i.e., the third target time).

[0163] The specific moments mentioned above refer to the activation of Scell ​​1, the entry of Scell ​​1 into a non-dormancy state, or the effective moment of BWPswitching; or

[0164] The aforementioned specific time is a certain time after the Scell ​​activation time, a certain time after the Scell ​​enters the non-dormancy state, or a certain time after the BWP switching time; or

[0165] The specific time mentioned above refers to the time when RRC signaling is configured.

[0166] In the above possible implementations, the method may further include: if the scheduling configuration information indicates that the second cell is scheduled by the first cell, then determining the terminal's undesirable behavior through a pre-agreed agreement, wherein the terminal's undesirable behavior includes at least one of the following:

[0167] The UE receives control signaling to deactivate the first cell; that is, the UE does not expect to receive control signaling to deactivate the first cell, such as MAC CE.

[0168] Configure a cell deactivation timer for the first cell; that is, the UE does not expect to receive a cell deactivation timer configured for the first cell, for example, sCellDeactivationTimer.

[0169] Configure a BWP deactivation timer for the BWP that can be scheduled in the second cell on the first cell; for example, the UE does not want to configure bwpInactivityTimer for the BWP of the schedulable Pcell on Scell ​​1 of the scheduled Pcell, that is, it does not want to deactivate the BWP of the schedulable Pcell.

[0170] The UE may switch from a schedulable BWP for the second cell to a non-schedulable BWP for the first cell. For example, the UE may not want to switch the Scell ​​1 of the scheduled Pcell from a schedulable BWP for the PCell to a non-schedulable BWP for the PCell.

[0171] Through the above possible implementation methods, the UE does not expect the first cell to switch to the state of the unschedulable second cell, so as to ensure the normal scheduling of the second cell by the first cell.

[0172] In one possible implementation, the method further includes: if the scheduling configuration information indicates that the second cell is scheduled by the first cell, then at least one of the following is ignored:

[0173] Control signaling for deactivating the first cell; that is to say

[0174] Configure a cell deactivation timer for the first cell;

[0175] Configure a BWP deactivation timer for the BWP that can be scheduled to the second cell on the first cell;

[0176] Control information indicating a switch from a BWP in the first cell that can be scheduled to the second cell to a BWP in the second cell that cannot be scheduled.

[0177] Optionally, among the above possible implementations, the executing entity can be a terminal, that is, the network-side device can perform any of the above corresponding operations, but the terminal ignores them, that is, they do not take effect.

[0178] The technical solution provided in this application embodiment receives scheduling configuration information, wherein the scheduling configuration information indicates that the second cell of the terminal is scheduled by the first cell, and the second cell is capable of self-scheduling. It also determines the activity status of the first cell and, based on the scheduling configuration information and the activity status, determines the scheduling method of the second cell. The technical solution provided in this application embodiment, when the second cell is scheduled by the first cell and the second cell is capable of self-scheduling, determines the scheduling method of the second cell based on the activity status of the first cell and the scheduling configuration information. This provides a scheme for determining the scheduling method when the first cell schedules the second cell, solving the problem of how to determine the cell scheduling method when scheduling a Pcell through an Scell.
