Communication processing methods, apparatus, devices and readable storage media

[0001] Cross-reference to related applications

[0002] This disclosure claims priority to Chinese Patent Application No. 202411847167.1, filed in China on December 16, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, specifically to a communication processing method, apparatus, device, and readable storage medium. Background Technology

[0004] For User Equipment (UE) in Radio Resource Control (RRC) idle state (RRC_IDLE) or RRC inactive state (RRC_INACITVE), cell selection or reselection is performed based on Radio Resource Management (RRM) measurements. Specific reselection priority and other information can be obtained by the terminal through system messages or RRC Release messages. After performing cell selection or reselection, the terminal will camp on a specific cell, obtain system messages, and listen for paging, etc. The network is unaware of the terminal's camp until the terminal accesses and enters connected state within that cell, at which point the cell becomes aware of it.

[0005] For RRC-connected UE mobility, i.e., handover, it is entirely or partially based on network configuration or network indication. For traditional handover (HO) and Layer 1 or Layer 2 Triggered Mobility (L1 / L2 Triggered Mobility, LTM), the serving cell determines whether the terminal should change its serving cell and indicates the target cell via Layer 3 or Layer 2 signaling. For LTM, the serving cell pre-configures the configurations available for potential target cells. For Conditional Handover (CHO), the serving cell provides multiple potential target cell access and applicable configurations after access through RRC configuration, and provides the conditions for the terminal to access each candidate target cell. When the conditions are met, the terminal initiates access and hands over to the corresponding cell.

[0006] For UEs in different states, how to make the UE camp or be served on a cell that supports subband full duplex (SBFD) as much as possible is an urgent problem to be solved. Summary of the Invention

[0060] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0061] The term "comprising," and any variations thereof, used in this disclosure and the claims are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus. Furthermore, the use of "and / or" in the specification and claims indicates at least one of the connected objects, such as A and / or B, indicating the inclusion of A alone, B alone, or both A and B.

[0062] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0063] To address the problem that current large-scale pre-trained models generate answers inconsistent with human preferences, this disclosure provides a communication processing method based on generative pre-trained models. This method iteratively improves the pre-trained model by sampling from high reward quantiles during the exploration process and using KL divergence (Kullback-Leibler Divergence) penalty during the learning process, shifting its distribution to samples with increasingly higher rewards without deviating too far from the original model.

[0064] To facilitate understanding of the embodiments of this disclosure, the following technical points will be introduced first:

[0065] Regarding Subband Full Duplex (SBFD).

[0066] In Time Division Duplex (TDD) systems, on a single symbol within a carrier, both the base station and the terminal can only perform uplink or downlink transmissions, not simultaneously. Therefore, TDD systems suffer from significant uplink / downlink transmission latency and limited uplink capacity and coverage. To reduce transmission latency and improve uplink coverage and capacity in TDD systems, the Related Technology Duplex Evolution Research Project (SI) has investigated Subband Non-overlapping Full Duplex (SBFD). SBFD divides the carrier bandwidth into several subbands occupying different frequency resources, allowing the base station to perform simultaneous uplink and downlink transmissions on a single symbol. Currently, the Related Technology SBFD Work Item (WI) is discussing relevant standard schemes for SBFD. The meeting concluded that subbands can be configured on traditional downlink or flexible time slots or symbols to enable base stations to achieve SBFD. Time slots or symbols configured with subbands are called SBFD time slots or symbols, while time slots or symbols without subbands are called non-SBFD time slots or symbols.

[0067] Referring to Figure 1, an embodiment of this disclosure provides a communication processing method applied to a terminal, which may be a terminal that can recognize the SBFD symbol (SBFD-aware UE). The specific steps include: step 11 and step 12.

[0068] Step 11: Receive first information, the first information including at least one of the following: information that the first cell supports SBFD, SBFD configuration information of the first cell, priority information, the first cell including at least one of target cell, candidate cell, and neighboring cell, the priority information being used to indicate the priority of frequency points or cells that support SBFD;

[0069] In this embodiment, the terminal can be in RRC_IDLE state, RRC_INACTIVE state, or RRC_CONNECTED state.

[0070] Step 12: In response to the first information, change the serving cell to an SBFD cell.

[0071] In one implementation, if the first information includes priority information, the terminal can determine the frequency points that support SBFD for priority measurement based on the priority information in the first information.

[0072] In one embodiment of this disclosure, the first information is an RRC reconfiguration message, which includes a handover configuration; or the first information is a handover execution instruction. In response to the first information, a serving cell change is performed, including:

[0074] Access to the target cell is achieved through SBFD resources.

[0075] In one embodiment of this disclosure, the first information is a conditional handover configuration, or a mobility conditional LTM configuration triggered by conditional layer 1 and / or layer 2. In response to the first information, a serving cell change is performed, including:

[0076] In response to the first information, an SBFD cell is selected as the target cell from multiple candidate cells;

[0077] Access to the target cell is achieved through SBFD resources.

[0085] In one embodiment of this disclosure, the RACH configuration information includes at least one of the following: whether an indication is supported for the terminal to initiate access on SBFD resources, SBFD resources, and traditional access resources.

[0086] In one embodiment of this disclosure, the first information is an LTM cell change command, and in response to the first information, a serving cell change is performed, including:

[0087] Based on the first information, the terminal accesses the target cell via SBFD resources, wherein the first information is used to instruct the terminal to access the target cell using SBFD resources.

[0088] In one embodiment of this disclosure, when the priority is included in the first information, the first information is carried in a system message or a radio resource control release message.

[0089] In one embodiment of this disclosure, when the priority is not included in the first information, a serving cell change is performed in response to the first information, including:

[0090] The serving cell is changed based on the frequency point or cell priority that the terminal autonomously determines to support SBFD.

[0091] In this disclosure, the terminal receives first information, which includes at least one of the following: information that the first cell supports SBFD, SBFD configuration information of the first cell, and priority information. The first cell includes at least one of a target cell, a candidate cell, and a neighboring cell. The priority information is used to indicate the priority of the frequency point or cell that supports SBFD. In response to the first information, the terminal performs a serving cell change. The changed serving cell is an SBFD cell, so that the terminal can camp on or be served on a cell that supports SBFD as much as possible and obtain the additional gains brought by SBFD.

[0092] Referring to Figure 2, an embodiment of this disclosure also provides a communication processing method applied to a source base station, the specific steps of which include: step 21.

[0093] Step 21: Send first information to the terminal, the first information including at least one of the following: information that the first cell supports SBFD, SBFD configuration information of the first cell, priority information, the first cell including at least one of target cell, candidate cell, and neighboring cell;

[0094] The first information is used by the terminal to change the serving cell, and the changed serving cell is an SBFD cell. The priority information is used to indicate the priority of the frequency point or cell that supports SBFD.

[0095] In one embodiment of this disclosure, the method further includes:

[0096] Send second information to the target base station or candidate base station, the second information including at least one of the following: information that the serving cell supports SBFD, and information that the terminal supports SBFD.

[0097] In one embodiment of this disclosure, the method further includes:

[0098] Receive third information sent by the target base station or candidate base station, the third information including at least one of the following: information that the target base station or candidate base station supports SBFD, SBFD configuration information of the target cell or candidate cell, and RACH configuration information.

[0099] In one embodiment of this disclosure, the method further includes:

[0100] Send a fourth message to the target base station or candidate base station. The fourth message is used to request a handover. The fourth message includes at least one of the following: terminal SBFD capability, SBFD configuration information of the serving cell, RACH configuration information, terminal-related service information, and terminal-specific SBFD configuration information.

[0101] Optionally, the fourth piece of information may be a switching request.

[0102] In one embodiment of this disclosure, the method further includes:

[0103] The system receives fifth information sent by the target base station or candidate base station. The fifth information is used to confirm the handover request. The fifth information includes at least one of the following: target cell or candidate cell SBFD configuration information, and an indication of whether SBFD resources are enabled or disabled.

[0104] Optionally, the fifth piece of information can be a switch confirmation feedback.

[0105] In this disclosure, the source base station sends first information to the terminal, the first information including at least one of the following: information that the first cell supports SBFD, SBFD configuration information of the first cell, and priority information. The first cell includes at least one of target cell, candidate cell, and neighboring cell. The priority information is used to indicate the priority of the frequency point or cell that supports SBFD. This enables the terminal to change its serving cell in response to the first information. The changed serving cell is an SBFD cell, so that the terminal can camp on or be served by a cell that supports SBFD as much as possible and obtain the additional gains brought by SBFD.

[0106] The embodiments of this disclosure are described below with reference to Embodiment 1 and Embodiment 2.

[0107] Example 1: For UEs that can recognize the SBFD symbol in the connected state (SBFD-aware UE in RRC_CONNECTED state).

[0108] Step 0-1: Optionally, the interaction between the source base station and the candidate base station or the target base station during the establishment of the Xn interface is supported by SBFD.

[0109] For example, the source base station sends second information to the target base station or candidate base station, the second information including at least one of the following: information that the serving cell supports SBFD, and information that the terminal supports SBFD.

[0110] The source base station receives third information sent by the candidate base station or the target base station, the third information including information on SBFD supporting information of the candidate base station or the target base station.

[0111] Furthermore, the third information may also include at least one of the following: 1) SBFD configuration information of the target cell or candidate cell, such as SBFD configuration including but not limited to SBFD subband; 2) RACH configuration information, including the enable status of the two potential configuration methods and the corresponding configuration information.

[0112] Optionally, there are two potential configuration methods, including configuration method 1 and configuration method 2, wherein,

[0113] Configuration Method 1: Legacy RACH resources and SBFD resources are allocated to the UE through the same RACH configuration, but random access opportunities (RACH Occasion, RO) on the uplink subband located on the BFD sub-symbol or slot are available for SBFD UEs.

[0114] Configuration Method 2: Legacy RACH resources and SBFD resources are distributed to the UE through a separate RACH configuration.

[0115] Step 0-2: Optionally, the terminal sends the measurement results to the source base station.

[0116] Step 1: The source base station executes a handover decision (HO decision) to determine the handover configuration for the UE;

[0117] Optionally, the source base station performs a handover decision based on at least one of the measurement results reported by the terminal, considering network load conditions.

[0118] Optionally, the configuration switch includes: 1) configuring to perform a legacy switch (Legacy HO); 2) configuring to perform a conditional switch (Conditional Handover, CHO) or LTM or conditional LTM;

[0119] Step 2: The serving cell sends a handover request (HO request) (i.e., the fourth information) to the target base station (for legacy HO) or the candidate base station (for CHO, LTM, or conditional LTM);

[0120] Optionally, the switching request carries at least one of the following information:

[0121] 1) UE SBFD capability, for example, information about UE support for SBFD;

[0122] 2) SBFD configuration information of the serving cell, such as the SBFD subband configuration of the serving cell;

[0123] Optionally, the subband configuration includes at least one of a time domain indication and a frequency domain indication.

[0124] 3) RACH configuration information;

[0125] Optionally, the RACH configuration information includes at least one of the following: information indicating whether UE is supported to initiate access on SBFD resources, SBFD access resources, and traditional access resources (applicable to cells where SBFD is disabled or not supported).

[0126] 4) Terminal-related business information;

[0127] 5) Terminal-specific SBFD configuration information.

[0128] For example, the handover request may carry information that the UE supports SBFD. Optionally, if the serving cell is configured with SBFD, the handover request may also carry the serving cell SBFD subband, RACH configuration information, and may additionally carry terminal-related service information and / or terminal-specific SBFD configuration information.

[0129] Optionally, the source base station can select the target base station or the candidate base station based on at least one of the measurement results obtained in step 0, which provides information on whether the target cell or the candidate cell supports SBFD.

[0130] Optionally, if the source base station is configured with CHO or LTM, a handover request is sent to each candidate base station, carrying the above information.

[0131] Access control is performed on the target base station or candidate base station.

[0132] Step 3: If the target base station or candidate base station accepts the UE, a handover confirmation feedback (HO request Acknowledge) (i.e., the fifth information) is sent to the source base station.

[0133] Optionally, the switch confirmation feedback carries at least one of the following:

[0134] 1) Target cell or candidate cell SBFD configuration information;

[0135] 2) SBFD resource enable / disable indication.

[0136] The SBFD resource enable indicator indicates that SBFD resources can be used for access, while the SBFD resource disable indicator indicates that SBFD resources cannot be used for access.

[0137] Step 4: The source base station sends an RRC reconfiguration message (i.e., the first information) to the terminal. The RRC reconfiguration message includes at least one of the following: handover configuration (HO configuration), conditional handover configuration (CHO configuration), conditional LTM configuration, and LTM configuration.

[0138] Optionally, the switching configuration or conditional switching configuration or conditional LTM configuration or LTM configuration includes at least one of the following: SBFD configuration information of the target cell or candidate cell, RACH configuration information, and an indication of whether the SBFD resources of the target cell or candidate cell are enabled or disabled.

[0139] If the above configuration includes an indication to enable or disable SBFD resources, the UE needs to enable the use of the SBFD resources based on the serving cell or the cell newly accessed after accessing the target / candidate cell.

[0140] UE performs mobility configuration:

[0141] A: Switching from traditional methods.

[0142] If legacy HO is configured, the terminal will directly hand over and access the target cell based on the target cell configuration. If SBFD resource access is configured, the UE will select resources based on the corresponding rules. Optionally, the resource selection rules include, but are not limited to, at least one of signal quality, network configuration, user experience, and network status.

[0143] B: Conditional switching or conditional LTM.

[0144] If CHO, LTM, or conditional LTM is configured, the terminal stores the corresponding configuration and performs conditional measurement (based on L1 or L3 measurement) or L1 measurement. It is possible that the serving cell can simultaneously configure SBFD-supporting cells and non-SBFD-supporting cells for the UE and indicate them to the UE (possibly in the RRC configuration or in the system message; if indicated through the system message, the range of cells indicated will be greater than or equal to the range of UE candidate cells).

[0145] Optionally, network instructions or protocols specify access priority information for SBFD supporting cells and non-SBFD supporting cells.

[0146] For CHO, the UE can prioritize monitoring cells that support SBFD. Optionally, the way to identify SBFD supporting cells can be through network indication or by the UE itself, such as monitoring the SIBs of other cells.

[0147] If multiple cells simultaneously meet the execution conditions for CHO (Confirmation of Hazardous Access), the SBFD (Simplified SBFD) cell is selected first. When the conditions for a candidate cell are met, the UE uses its corresponding configuration for access. If SBFD resources are configured for access, the UE selects resources based on the corresponding rules. Alternatively, if the UE prioritizes all cells equally, when a cell meets the execution conditions, it determines whether it supports or enables SBFD access. If it does, the corresponding configuration is executed directly. If it does not support SBFD, the terminal may start a network-configured timer. If the timer expires and no SBFD-supporting cell meets the execution conditions, the UE accesses the target cell that currently does not support SBFD.

[0148] Optionally, the CHO or Conditional LTM configuration includes configurations for multiple candidate cells: each candidate cell configuration includes an execution condition and a set of configurations (e.g., configurations used during access and after accessing the target cell). An execution condition can include at least one measurement reporting event; for CHO, the event is based on L3 measurement results, while for Conditional LTM, it can be based on L1 or L3 measurement results. Taking CHO as an example, the execution condition for a candidate cell can include up to two events, such as A3 event and A5 event.

[0149] Optionally, the priority can be explicitly configured, such as associating each candidate cell with a priority value, where a larger value indicates a higher priority; or the priority can be implicitly configured, based on the order of the corresponding CHO configuration of the candidate cell in the configuration list, where a higher order indicates a higher priority.

[0150] For conditional LTM, the terminal operation is similar, but the criteria for measuring the execution condition are different from those for CHO.

[0151] For traditional LTM:

[0152] 1. If the network configures the UE to acquire the Tracking Area (TA) based on the PDCCH order, the PDCCH order can indicate whether the UE should use SBFD resources to send a preamble to acquire the TA;

[0153] 2. When the network issues an LTM cell switch command, it can additionally indicate whether to use SBFD resources. That is, the UE’s use of SBFD resources can be dynamically activated through the LTM cell switch command (the UE can choose the applicable resources, SBFD or legacy).

[0154] Example 2: The SBFD-aware UE is in the RRC_IDLE or RRC_INACTIVE state.

[0155] SBFD-aware UEs perform cell reselection based on the first information provided by system messages or RRC Release messages.

[0156] Optionally, the first information includes one or more of the following:

[0157] 1) An indication of the neighboring cell's SBFD support status, and possibly additional SBFD configuration information for the neighboring cell;

[0158] 2) Priority information, which is used to indicate the priority of frequency points or cells that support SBFD. For example, the priority information may reuse the existing priority indication method or be set as a reselection priority dedicated to SBFD. For example, the reselection priority dedicated to SBFD indicates that the frequency points that support SBFD have a higher priority than other frequency points.

[0159] For SBFD-aware UE:

[0160] 1) If the network does not indicate a reselection priority dedicated to SBFD, the UE will assume that the frequency point that supports SBFD has a higher priority. When there are multiple frequency points that support SBFD, their priority is consistent with the priority of frequency points that are not related to SBFD contained in the system message or RRC Release message.

[0161] 2) If the network indicates a reselection priority dedicated to SBFD, the UE sorts the frequency points according to the priority and performs measurements according to the sorting, ignoring the reselection priorities not dedicated to SBFD.

[0162] Referring to Figure 4, when a terminal performs cell selection or reselection, it first considers priority information. Priority information indicates the priority of frequencies or cells supporting SBFD. The UE will prioritize higher-priority frequencies or cells. If a cell on a frequency supporting SBFD meets the reselection criteria, the UE will camp on that SBFD-supporting cell. This ensures the terminal camps on a SBFD-supporting cell, thereby gaining the benefits of SBFD. From the network side, SBFD-supporting cells certainly prefer SBFD-supporting UEs for access, which is beneficial for network load balancing.
