Description

Information processing method, apparatus, and communication system TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND

[0002] Support for extended reality (XR, eXtended Reality) in 3GPP services and networks is currently being studied. XR is a general term for different types of reality. Different application areas of XR include, for example, entertainment, medicine, education, etc.

[0003] Extended reality (XR) refers to all real and virtual combined environments and human-machine interactions produced by computer technology and wearable devices. It includes representative forms such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and mixed and cross-domain areas.

[0004] VR is a rendered version of the published visual and audio scene. The rendering aims to simulate the visual and auditory sensory stimuli of the real world as naturally as possible when the observer or user moves within the limits defined by the application.

[0005] AR refers to providing additional information or artificially generated items or content overlaid on the user's current environment.

[0006] MR is an advanced form of AR in which some virtual elements are inserted into a physical scene with the aim of providing an illusion that these elements are part of the real scene.

[0007] 5G technology is studying key issues, solutions, and conclusions to support advanced media services, such as high data rate low latency (HDRLL) services, AR / VR / XR services, and haptic / multimodal (also known as multi-modal) communication services. Goals include:

[0008] Enhanced functionality to support multi-modal services:

[0009] - Study whether and how to enable applications to provide relevant haptic and multi-modal data to users at similar times (e.g., audio, video, and haptic data related to a particular time), with a focus on the need for enhanced policy control (e.g., QoS (Quality of Service) policy coordination).

[0010] Enhanced scheduling methods:

[0011] For uplink service, enhanced functions using latency or deadline information are studied to support uplink scheduling enhancement to achieve high XR capacity while meeting latency requirements or avoiding sending late PDUs (Protocol Data Units). Logical channel prioritization (LCP) is implemented at the terminal side, so it is necessary to consider minimizing the complexity of terminal devices.

The high-layer signaling may also be, for example, MAC (Medium Access Control) signaling; or referred to as a MAC CE (control element). However, the present application is not limited thereto.

[0062] Embodiments of the first aspect

[0063] The embodiments of the present application provide an information processing method, which is described from the terminal device side. FIG. 2 is a schematic diagram of an information processing method according to an embodiment of the present application. As shown in FIG. 2, the method comprises the following steps.

[0064] 201. The terminal device receives first information from a network device, the first information being used to indicate a priority of a logical channel when available data for transmission of the logical channel includes first data; and

[0065] 202. The terminal device performs resource allocation on the logical channel according to the first information.

[0066] According to the above-mentioned embodiments, the terminal device receives first information used to indicate a priority of a logical channel when available data for transmission of the logical channel includes first data, and performs resource allocation on the logical channel according to the first information. In this way, the priority of the logical channel in the logical channel priority processing process can be enhanced. By enhancing the priority of the logical channel, it is helpful to reasonably allocate resources for the logical channel, so as to ensure service performance and user experience.

[0067] In some embodiments, the first data may be various data with specific requirements. For example, the first data may include data with a delay requirement. For example, the first data may include or be data with a remaining time less than a first threshold.

[0068] In the LCP procedure of the existing terminal device technology, when allocating resources according to uplink grants, the selection order of logical channels is selected based on the priority of the logical channels, without considering the requirement of data in each logical channel for time delay. For example, the priority of some logical channels is low, but the data contained therein has a high requirement for time delay and a low remaining time, that is, a low time delay budget. These data may be preempted by data of relatively high priority logical channels, resulting in delay. In this way, time delay sensitive XR services may not meet the time delay requirement, thereby affecting the performance of XR services.

[0069] The priority of the logical channel including (containing) the first data with a remaining time less than the first threshold is indicated by the first information, and the first information is considered when allocating resources, so that the requirement of data in the logical channel for time delay can be considered, and the priority of the logical channel including the first data is set appropriately. In this way, it is helpful to allocate resources to the logical channel including the first data in priority, and further helpful to transmit the first data with short time delay requirement in priority. Taking the first data as XR data as an example, XR services can be better supported, thereby improving the user experience of XR and media services.

[0070] In some embodiments, the remaining time of the first data can include or be the remaining time to the expiration of a discard timer of the first data. The application is not limited thereto, and the remaining time can also have other meanings.

[0071] In some embodiments, the first threshold can be configured by RRC. For example, the first threshold can be configured in a logical channel configuration information element (IE) in an RRC reconfiguration message. For example, a first threshold field is added in a LogicalChanlelConfig IE. The application is not limited thereto, and the first threshold can also be configured in other ways.

[0072] In some embodiments, the first information can be configured by RRC. The application is not limited thereto, and the first information can also be configured in other ways.

[0073] In some embodiments, in the LCP procedure, resources are allocated according to the priority of the logical channels.

[0074] In some embodiments, the priority of the logical channel can be determined according to whether the data available for transmission of the logical channel includes the first data. The data available for transmission can also be referred to as the available data of the MAC layer, the data in the layer 2 buffer, the data waiting to be composed into a MAC PDU, the data waiting to be multiplexed and assembled, etc.

[0075] For example, in a case where the data available for transmission of the logical channel does not include the first data, the priority of the logical channel can be a configured default priority, e.g., indicated by the priority field in the LogicalChannelConfig IE in the RRCReconfiguration message; or

[0076] In a case where the data available for transmission of the logical channel includes the first data, the priority of the logical channel can be the priority corresponding to the first information; or

[0077] In a case where all the first data in the logical channel is allocated with resources, the priority of the logical channel can be the configured default priority.

[0078] In some embodiments, the value of the priority corresponding to the first information can be less than or equal to the value of the default priority. In other words, the priority corresponding to the first information can be higher than or equal to the default priority. In this way, the priority of the logical channel when including the first data can be set to be higher, which helps to prioritize the allocation of resources to the logical channel, thereby guaranteeing the latency requirement of the first data.

[0079] In some embodiments, the first information can be in various forms. For example, the first information can be at least one parameter, or a configuration.

[0080] Hereinafter, the method of the present application is exemplarily described with the first information being a first parameter as an example.

[0081] Whenever the UE performs new data transmission, the MAC entity of the UE needs to apply the LCP procedure.

[0082] A first parameter can be added to each logical channel of each MAC entity. The first parameter is configured by RRC, for controlling the scheduling of uplink data.

[0083] The first parameter, for example, can be called priorityDelayCritical, and the value range can be an integer between 1 and 16 (inclusive). The present application is not limited thereto, and the first parameter can also be other parameters.

[0084] The first parameter can be a new priority (i.e., the priority corresponding to the first parameter) configured for each logical channel, which is higher than or equal to the original priority (i.e., the default priority, also referred to as the original priority, etc.). For example, the value of the new priority of the logical channel is less than or equal to the original priority of the logical channel. The original priority is, for example, the configured default priority described above.

[0085] The first parameter sets the priority of the logical channel when the first data is included, and a larger priority value indicates a smaller priority.

[0086] The first data can be delay critical data, i.e., the remaining time of the data is less than the first threshold. The remaining time can refer to the remaining time to the discard timer of the first data.

[0087] The first data can refer to a MAC (Medium Access Control) SDU (service data unit) available for transmission, and each MAC SDU corresponds to a PDCP (Packet Data Convergence Protocol) SDU with a discard timer. The running value of the discard timer and the first threshold can be compared to determine whether the MAC SDU is the first data.

[0088] The remaining time can also refer to the remaining delay budget of the data, i.e., the remaining delay budget of the MAC SDU and the first threshold can be compared to determine whether it is the first data.

[0089] The first data can also be referred to as emergency data, delay sensitive data, short delay data, short remaining time data, etc.

[0090] The first threshold can be configured by RRC signaling.

[0091] For example, the first threshold can be configured in the LogicalChannelConfig information element (IE) in the RRCReconfiguration message, i.e., a first threshold field, such as remainingTimeThresholdLCH, is added to the LogicalChannelConfig IE to configure the first threshold for each logical channel. That is, the first threshold is a parameter for each logical channel, which sets a threshold for the remaining time of the data available for transmission of the logical channel to determine whether to apply the first parameter. For example, the first threshold is in milliseconds, and the value range can be 1 to 64 milliseconds.

[0092] Alternatively, the first threshold configuration can also be added to the MAC-CellGroupConfig IE in the RRCReconfiguration message, i.e., the first threshold configuration can be performed in the cell group configuration of the MAC layer.

[0093] The configuration of the first threshold value can be a single field, and only one first threshold value needs to be configured based on the cell group. That is, the same first threshold value is used for all logical channels in the cell group.

[0094] The first threshold value configuration can be based on each logical channel, that is, each first threshold value corresponds to a logical channel identity (Logical Channel Identity). The first threshold value can also be based on each logical channel group (LCG, logical channel group), that is, each first threshold value corresponds to a logical channel group identity (LCG-Id). If the configuration is based on the logical channel group, all logical channels in a logical channel group share the same first threshold value. Therefore, when a logical channel determines whether to include the first data, the first threshold value configured by the logical channel group to which the logical channel belongs is used for comparison and judgment.

[0095] Taking the configuration of the first threshold value based on the logical channel as an example, the definition of the MAC-CellGroupConfig IE in the related specification or standard can be enhanced as follows:

[0096] In some embodiments, the determination of the first data can also be determined by the terminal device.

[0097] There are two methods for using the first parameter and the first threshold value to configure resources:

[0098] Method a1: When the data available for transmission of a logical channel includes the first data, the priority of the logical channel is the value of the first parameter if the first parameter is configured; otherwise, the default priority is used. The first data refers to the data whose remaining value of the discard timer of the associated PDCP SDU indicates a remaining time less than the first threshold value. When all the first data in the logical channel has been allocated resources, the priority of the logical channel is set to the default priority. A larger value of the first parameter indicates a lower priority.

[0099] Method a2: The priority of the logical channel is redefined. That is, when the logical channel does not include the first data, the logical channel priority uses the default priority configuration (also referred to as the initial / original / original / original / traditional priority configuration), and when the logical channel includes the first data, the logical channel priority uses the first parameter configuration if configured. A larger value of the logical channel priority indicates a lower priority. The default priority configuration and the first parameter are configured by RRC.

[0100] In some embodiments, in the LCP procedure, the resource allocation procedure for each logical channel can be divided into two stages. The first stage is resource allocation before the PBR (prioritized bit rate) requirement of each logical channel is met. The second stage is a second resource allocation for each logical channel based on priority if there is remaining resource after the PBR requirement of each logical channel (i.e., all selected logical channels) is met. The PBR requirement is represented by a variable Bj (also referred to as token number) of each logical channel. The calculation of Bj is related to PBR and BSD (bucket size duration), and the specific calculation method can refer to related technologies.

[0101] In some embodiments, before the PBR requirement of all selected logical channels is met (i.e., the first stage), the priority of a logical channel is determined according to whether the data available for transmission of the logical channel includes first data at the beginning of resource allocation.

[0102] For example, if the data available for transmission of the logical channel includes first data, the priority of the logical channel is the priority corresponding to the first information. Or, if the data available for transmission of the logical channel does not include first data, the priority of the logical channel is the default priority.

[0103] In some embodiments, the priority of the logical channel can not be changed or updated during the resource allocation of the first stage. In this way, the determination of the priority can be simplified, which helps to reduce the complexity of the terminal device.

[0104] In some embodiments, the priority of the logical channel can also be changed or updated during the resource allocation of the first stage. For example, when all first data in a certain logical channel is allocated with resource, the priority of the logical channel can be updated to the default priority. In this way, the priority of the logical channel can be updated in time according to whether the first data in the logical channel is allocated with resource, which can further improve the rationality of resource allocation and help to further improve the service performance and user experience.

[0105] In some embodiments, in the case where the priority of the logical channel is updated, the terminal device can perform resource allocation for the logical channel according to the updated priority of the logical channel. For example, the logical channel is reordered and reselected according to the updated priority of the logical channel to continue resource allocation.

[0106] In some embodiments, in the resource allocation of the logical channel, the resource allocation is performed for the logical channel with Bj greater than 0 in the order of priority from high to low. In this way, the PBR requirement of the logical channel can be reliably met.

[0107] However, the present application is not limited thereto. For example, in the resource allocation for the logical channel whose data available for transmission includes the first data, the Bj of the logical channel can not be considered, and the allocation can be performed in the order of priority from high to low. That is, in the resource allocation for the logical channel whose data available for transmission includes the first data, the Bj of the logical channel is not considered, and the allocation is performed in the order of priority from high to low together with other logical channels whose Bj is greater than 0. In this way, the logical channel including the first data can be further preferentially allocated resources.

[0108] In some embodiments, after the priority bit rate requirements of all selected logical channels are met (i.e., the second stage), the priority of a logical channel can be determined according to whether the data available for transmission of the logical channel includes the first data at the beginning of the resource allocation after the priority bit rate requirements are met (i.e., the second stage of resource allocation).

[0109] For example, at the beginning of the resource allocation of the second stage:

[0110] The data available for transmission of the logical channel includes the first data, i.e., there is still first data in the logical channel that has not been allocated resources, and the priority of the logical channel is the priority corresponding to the first information; or

[0111] The data available for transmission of the logical channel does not include the first data or all first data in the logical channel has been allocated resources, and the priority of the logical channel is the default priority.

[0112] In some embodiments, during the resource allocation of the second stage, the priority of the logical channel can not be changed or updated. In this way, the determination of the priority can be simplified, which helps to reduce the complexity of the terminal device.

[0113] In some embodiments, during the resource allocation of the second stage, the priority of the logical channel can also be changed or updated. For example, during the resource allocation after the priority bit rate requirements are met, when all first data in a certain logical channel has been allocated resources, the priority of the logical channel is updated to the default priority. In this way, the priority of the logical channel can be updated in time according to whether the first data in the logical channel has been allocated resources, which can further improve the rationality of resource allocation and help to further improve service performance and user experience.

[0114] In some embodiments, during the resource allocation of the second stage, when the priority of a logical channel is updated, the terminal device can perform resource allocation for the logical channel according to the updated priority of the logical channel. For example, the logical channels are reordered and reselected according to the updated priority of the logical channels to continue resource allocation. In some embodiments, the terminal device can perform resource allocation for the logical channel according to the updated priority of the logical channel. For example, the logical channels are reordered and reselected according to the updated priority of the logical channels to continue resource allocation.

[0115] In some embodiments, when more than one logical channel has the same priority, the terminal device can prioritize the logical channel including the first data in resource allocation. In this way, resources can be allocated to the logical channel including the first data more timely.

[0116] Hereinafter, the method of the embodiments of the present application is exemplarily described with the first information as the first parameter, the resource allocation including the first-stage resource allocation and / or the second-stage resource allocation as an example.

[0117] For the resource allocation before the PBR requirement is met (the first-stage resource allocation), the following four methods can be enhanced to prioritize the resource allocation of the first data:

[0118] Method b1: At the beginning of the resource allocation, the priority of the logical channel is determined according to whether the logical channel contains the first data. The priority selection does not change during the first-stage resource allocation. That is, the ordering of the logical channels does not change during the first stage, and each logical channel is only selected once.

[0119] The LCP process of the MAC layer is enhanced as follows:

[0120] When a new transmission is operated, the MAC entity needs to perform the following steps:

[0121] The resources are allocated to the logical channels as follows: among the logical channels selected based on the limit condition for the uplink grant, the logical channels with Bj greater than 0 are allocated resources in order of priority from high to low. When a logical channel contains the first data, the priority of the logical channel uses the priority corresponding to the first parameter if the first parameter is configured; otherwise, the original priority configuration (the configured parameter is, for example, called priority) is used.

[0122] During the resource allocation in this stage, all Bj of the logical channels are allocated to be less than or equal to 0, or the resources are all allocated. The resource allocation refers to allocating the resources of the uplink grant to the data, such as encapsulating the MAC SDU corresponding to the data in the MAC PDU for transmission.

[0123] Method b2: At the beginning of the resource allocation, the priority of the logical channel is determined according to whether the logical channel contains the first data. During the first-stage resource allocation, if all the first data of a logical channel are allocated resources, the priority of the logical channel is restored to the original priority value. Then, the logical channels are reordered and reselected based on the updated logical channel priority to continue the resource allocation. The remaining steps are the same as those of method b1.

[0124] The LCP procedure of MAC layer is enhanced as follows:

[0125] When a new transmission is operated, the MAC entity shall perform the following steps:

[0126] The resources are allocated to the logical channels as follows: among the logical channels selected based on the restriction condition for uplink grant, the logical channels with Bj greater than 0 are allocated resources in the order of priority from high to low. When a logical channel contains first data, the priority of the logical channel uses the priority corresponding to the first parameter if the first parameter is configured; otherwise, the original priority configuration is used. When all the first data of a logical channel are allocated resources, the priority of the logical channel is set to the original priority configuration, and the logical channels can be reselected based on the updated priority.

[0127] Method b3: The logical channels containing first data are not restricted by PBR. That is, the logical channels containing first data are not considered in terms of the size of Bj, and the condition of Bj > 0 is not required to be met.

[0128] The LCP procedure of MAC layer is enhanced as follows:

[0129] When a new transmission is operated, the MAC entity shall perform the following steps:

[0130] The resources are allocated to the logical channels as follows: among the logical channels selected based on the restriction condition for uplink grant, the logical channels with Bj greater than 0 and the logical channels containing first data (without considering the value of Bj) are allocated resources in the order of priority from high to low. When a logical channel contains first data, the priority of the logical channel uses the priority corresponding to the first parameter if the first parameter is configured; otherwise, the original priority configuration is used.

[0131] Without considering the value of Bj means that even if Bj < 0, the logical channel can still be allocated resources in the first stage.

[0132] Another enhancement method is that when the value of Bj is updated each time, the value of Bj is increased to the value that can contain the data amount of the head data of the queue and the last first data if applicable. In this way, when the logical channel selection is performed, the resources can still be allocated according to the condition of Bj > 0.

[0133] Method b4: If two logical channels have the same priority, the logical channel containing first data is preferentially allocated resources. That is, if multiple logical channels have the same priority, the logical channel using the first parameter as the priority can be considered to have a higher priority.

[0134] The above methods can be used alone or in combination. The above methods and combinations thereof are described below by way of example with reference to the accompanying drawings.

[0135] Figure 3 is a schematic diagram of logical channels on the UE side according to an embodiment of the application. Figure 3 shows the buffer status information, Bj information, and priority configuration information of the logical channels. As shown in Figure 3, the data available for transmission of logical channel 1 (LCH1) includes non-first data SDU1, SDU2, and SDU3; the data available for transmission of logical channel 2 (LCH2) includes first data SDU4, SDU5 and non-first data SDU6, SDU7; and the data available for transmission of logical channel 3 (LCH3) includes non-first data SDU8, SDU9, SDU10, and SDU11 and first data SDU12, SDU13.

[0136] The default priorities (denoted by priority) of LCH1, LCH2, and LCH3 are 2, 3, and 4, respectively. LCH2 and LCH3 include first data (e.g., delay critical data), and the priorities (denoted by priorityDelayCritical) indicated by the first parameters of LCH2 and LCH3 are 1 and 2, respectively.

[0137] Figure 4 is a schematic diagram of the resource allocation result (i.e., the result of grouping of MAC PDUs) after using method b1 according to an embodiment of the application. As shown in Figure 4, when initially selecting logical channels, LCH2 has first data, so the first parameter is used, which is configured as 1 and is the highest priority among the three logical channels, so LCH2 is selected first, and resource allocation is performed for LCH2 until the Bj condition is met. LCH3 has first data, so the first parameter is used, which is configured as 2. LCH1 and LCH3 have the same priority (LCH1 priority, LCH3 priorityDelayCritical = 2) at this time, so LCH1 with the smaller logical channel index value can be selected, and resource allocation is performed for LCH1 until the Bj condition is met. Finally, resource allocation is performed for LCH3.

[0138] Figure 5 is a schematic diagram of the resource allocation result after using method b2 of the embodiments of the present application. As shown in Figure 5, when making logical channel selection for the first time, LCH2 is selected first because it has the first data and the first parameter is configured as 1, which is the highest priority among the three logical channels. After the first data SDU4 and SDU5 are allocated resources, the priority of LCH2 is restored to 3, and the logical channels are reordered according to their priorities. LCH1 and LCH3 have the same priority (LCH1 priority, LCH3 priorityDelayCritical = 2) at this time, and LCH1 with a smaller logical channel index value can be selected for resource allocation until the Bj condition is met. Finally, LCH3 is allocated resources.

[0139] Figure 6 is a schematic diagram of the resource allocation result after using the combination of methods b2, b3 and b4 of the embodiments of the present application. As shown in Figure 6, when making logical channel selection for the first time, LCH2 is selected first because it has the first data and the first parameter is configured as 1, which is the highest priority among the three logical channels. After the first data SDU4 and SDU5 are allocated resources, the priority of LCH2 is restored to 3, and the logical channels are reordered according to their priorities (method b2). LCH1 and LCH3 have the same priority (LCH1 priority, LCH3 priorityDelayCritical = 2) at this time, and LCH3 with the first data in the queue is selected for resource allocation (method b4). After SDU12 is allocated, although the Bj condition has been met, the allocation continues because there is still first data (SDU13) in the queue, and SDU13 can also be allocated resources (method b3).

[0140] By using different methods, the first data can be preferentially allocated resources, and part or all of the first data can be included in the MAC PDU for transmission, thereby reducing the delay of the first data.

[0141] For resource allocation after meeting the PBR requirement (second stage resource allocation), the enhancement method for the first data is similar to the first stage method. Since Bj has been met in the first stage, Bj does not need to be considered in the second stage, and therefore the first stage method b3 is not applicable, and the other three methods can be used similarly.

[0142] For resource allocation after meeting the PBR requirement, i.e., after the first stage of resource allocation, if there is still remaining resources, the following three methods can be used to enhance the resource allocation of the first data:

[0143] Method c1 : At the beginning of the second stage resource allocation, the priority of a logical channel is determined according to whether it contains first data or not. The selection of priority is not changed during the process of the second stage resource allocation. That is, the ordering of logical channels will not be changed during the second stage, and each logical channel will be selected only once.

[0144] The LCP procedure of MAC layer is enhanced as follows:

[0145] If there is still resource left, all logical channels (regardless of the value of Bj) are served (resource allocation) in order of priority from high to low among the logical channels selected based on the restriction condition for the uplink grant until the data of the logical channels is completed for resource allocation or the uplink grant is exhausted. When a logical channel contains first data, the priority of the logical channel uses the priority corresponding to the first parameter if the first parameter is configured; otherwise, the original priority configuration is used (the configured parameter is called priority).

[0146] Method c2 : At the beginning of the second stage resource allocation, the priority of a logical channel is determined according to whether it contains first data or not. During the process of the second stage resource allocation, if all first data of a logical channel is allocated resource, the priority of the logical channel is restored to the original priority value. Then the logical channels are reordered and reselected based on the updated priority of the logical channels to continue resource allocation.

[0147] The LCP procedure of MAC layer is enhanced as follows:

[0148] If there is still resource left, all logical channels (regardless of the value of Bj) are served (resource allocation) in order of priority from high to low among the logical channels selected based on the restriction condition for the uplink grant until the data of the logical channels is completed for resource allocation or the uplink grant is exhausted. When a logical channel contains first data, the priority of the logical channel uses the priority corresponding to the first parameter if the first parameter is configured; otherwise, the original priority configuration is used (the configured parameter is called priority). When all first data of a logical channel is allocated resource, the priority of the logical channel is set to the original priority configuration, and based on the updated priority, the logical channels may need to be reselected.

[0149] Method c3 : If two logical channels have the same priority, the logical channel containing first data is allocated resource first. That is, if multiple logical channels have the same priority, the logical channel using the first parameter as the priority can be considered to have a higher priority.

[0150] The LCP procedure of the MAC layer is enhanced as follows:

[0151] If there are remaining resources, among the logical channels selected based on the restriction condition for the uplink grant, all the logical channels (regardless of the value of Bj) are served (resource allocation) in order of priority from high to low until the data of the logical channel is completed or the uplink grant is exhausted. If there are multiple logical channels configured with the same priority, the logical channel using the first parameter as the logical channel priority (i.e., the logical channel containing the first data) should be preferentially served. If there are multiple logical channels configured with the same priority and both using the conventional priority configuration (priority) or using the first parameter configuration, they need to be served equally.

[0152] The above methods can be used alone or in combination.

[0153] As mentioned above, when the UE receives the uplink grant, before resource allocation, the UE selects the logical channel, and only the logical channel meeting certain restriction conditions (also referred to as restriction conditions) is allocated resources. Hereinafter, the selection of the logical channel is exemplarily described.

[0154] In some embodiments, the method can further include: the terminal device selecting a logical channel, and allocating resources to the selected logical channel. In the selection of the logical channel, the terminal device does not limit the logical channel whose data available for transmission includes the first data by any restriction condition; or relaxes one or more restriction conditions for the logical channel whose data available for transmission includes the first data; or uses a new restriction condition for the logical channel whose data available for transmission includes the first data.

[0155] In this way, it helps to increase the opportunity of the logical channel including the first data being selected, so as to further preferentially allocate resources to the logical channel.

[0156] In some embodiments, the new restriction condition can include at least one of the following:

[0157] Second information indicating a list of subcarrier spacings allowed when the logical channel contains the first data;

[0158] Third information indicating a maximum PUSCH duration when the logical channel contains the first data;

[0159] Fourth information indicating whether a type 1 configured grant is allowed when the logical channel contains the first data;

[0160] Fifth information indicating a serving cell allowed when the logical channel contains the first data;

[0161] sixth information indicating a list of configured grants allowed when the logical channel contains the first data;

[0162] seventh information indicating a physical layer priority index allowed when the logical channel contains the first data;

[0163] eighth information indicating a HARQ mode allowed when the logical channel contains the first data.

[0164] The second to eighth information indicating the restriction condition can be referred to as a parameter or a configuration.

[0165] In some embodiments, the new restriction condition can be pre-configured for each logical channel by RRC. The application is not limited thereto, and the new restriction condition can also be configured to the terminal device by other manners.

[0166] Hereinafter, the method of the application is exemplarily described by taking the first to eighth information as the first to eighth parameters as examples.

[0167] In order to ensure that the first data can be transmitted in time, the restriction condition can be relaxed for the logical channel containing the first data. The enhancement of the logical channel restriction can have the following three methods.

[0168] Method d1: When selecting a logical channel, no restriction is made to the logical channel containing the first data.

[0169] When the MAC entity performs a new transmission, a logical channel meeting the following conditions and all logical channels containing the first data (without meeting any of the following conditions) are selected for each uplink grant. The following conditions include but are not limited to: if the logical channel is configured with allowedSCS-List, and the set of allowed subcarrier spacing index values in the configuration includes the subcarrier spacing index associated with the uplink grant; if the logical channel is configured with maxPUSCH-Duration, the configuration is greater than or equal to the duration of PUSCH (Physical Uplink Shared CHannel) transmission associated with the uplink grant, etc.

[0170] Method d2: When selecting a logical channel, one or more condition restrictions are relaxed for the logical channel containing the first data. That is, certain conditions are not applicable to the logical channel containing the first data.

[0171] For example, for the restriction of allowedSCS-List, the logical channel containing the first data can ignore the restriction.

[0172] The enhancement method for all the restriction conditions is as follows:

[0173] When the MAC entity performs a new transmission, for each uplink grant, select the logical channel(s) that meet the following conditions:

[0174] If a logical channel that does not contain the first data is configured with allowedSCS-List, and the set of allowed subcarrier spacing index values in the configuration includes the subcarrier spacing index associated with the uplink grant;

[0175] If a logical channel that does not contain the first data is configured with maxPUSCH-Duration, and the configuration is greater than or equal to the duration of PUSCH (Physical Uplink Shared CHannel) transmission associated with the uplink grant;

[0176] If a logical channel that does not contain the first data is configured with configuredGrantType1Allowed, and the value of the configuration is set to "true" when the uplink grant is a Type 1 configured grant;

[0177] If a logical channel that does not contain the first data is configured with allowedServingCells, and the configuration includes the cell information associated with the uplink grant;

[0178] If a logical channel that does not contain the first data is configured with allowedCG-List, and the configuration includes the configured grant index associated with the uplink grant;

[0179] If a logical channel that does not contain the first data is configured with allowedPHY-PriorityIndex, and the configuration includes the priority index associated with the dynamic uplink grant;

[0180] If a logical channel that does not contain the first data is configured with allowedHARQ-mode, and the configuration includes the allowed uplink HARQ (Hybrid Automatic Repeat Request) mode associated with the uplink grant.

[0181] Method d3: A new set of logical channel restriction conditions is configured for each logical channel. When the logical channel contains the first data, the new restriction conditions are used.

[0182] For example, a new parameter is configured for each logical channel, indicating that when the logical channel contains the first data, one or more of the following parameters are used as conditions for the selection of the logical channel:

[0183] a list of allowed subcarrier spacings when the logical channel contains the first data (the second parameter), a maximum PUSCH duration when the logical channel contains the first data (the third parameter), whether type 1 configured grant is allowed when the logical channel contains the first data (the fourth parameter of Boolean type), a serving cell allowed when the logical channel contains the first data (the fifth parameter), a list of configured grants allowed when the logical channel contains the first data (the sixth parameter), a physical layer priority index allowed when the logical channel contains the first data (the seventh parameter), a HARQ mode allowed when the logical channel contains the first data (the eighth parameter), and the like.

[0184] The enhanced logical channel selection method is:

[0185] When the MAC entity performs a new transmission, a logical channel meeting the following conditions is selected for each uplink grant:

[0186] If the logical channel is configured with allowedSCS-List, the second parameter is not configured or does not contain the first data, and the set of allowed subcarrier spacing index values in the configuration includes the subcarrier spacing index associated with the uplink grant, or the second parameter is configured and contains the first data, and the set of allowed subcarrier spacing index values in the configuration includes the subcarrier spacing index associated with the uplink grant;

[0187] If the logical channel is configured with maxPUSCH-Duration, the third parameter is not configured or does not contain the first data, and the configuration is greater than or equal to the duration of the PUSCH (Physical Uplink Shared CHannel) transmission associated with the uplink grant, or the third parameter is configured and contains the first data, and the configuration (the third parameter configuration) is greater than or equal to the duration of the PUSCH (Physical Uplink Shared CHannel) transmission associated with the uplink grant;

[0188] If the logical channel is configured with configuredGrantType1Allowed, the fourth parameter is not configured or does not contain the first data, and the configuration is set to "true" when the uplink grant is a type 1 configured grant, or the fourth parameter is configured and contains the first data, and the configuration is set to "true" when the uplink grant is a type 1 configured grant;

[0189] If the logical channel is configured with allowedServingCells, the fifth parameter is not configured or does not contain the first data, and the configuration includes the cell information associated with the uplink grant, or the fifth parameter is configured and contains the first data, and the configuration includes the cell information associated with the uplink grant;

[0190] If the logical channel is configured with allowedCG-List, the sixth parameter is not configured or the first data is not included, and the configuration includes the configured grant index associated with the uplink grant, or the sixth parameter is configured and the first data is included, and the configuration includes the configured grant index associated with the uplink grant.

[0191] If the logical channel is configured with allowedPHY-PriorityIndex, the seventh parameter is not configured or the first data is not included, and the configuration includes the priority index associated with the dynamic uplink grant, or the seventh parameter is configured and the first data is included, and the configuration includes the priority index associated with the dynamic uplink grant.

[0192] If the logical channel is configured with allowedHARQ-mode, the eighth parameter is not configured or the first data is not included, and the configuration includes the allowed uplink HARQ (Hybrid Automatic Repeat Request) mode associated with the uplink grant, or the eighth parameter is configured and the first data is included, and the configuration includes the allowed uplink HARQ (Hybrid Automatic Repeat Request) mode associated with the uplink grant.

[0193] These new conditional parameters are pre-configured for each logical channel by RRC.

[0194] In some embodiments, the method can further include: sending, by the terminal device, uplink data to the network device.

[0195] In some embodiments, the uplink data includes data available for transmission in the logical channel.

[0196] In some embodiments, the uplink data includes the first data.

[0197] In some embodiments, the method can further include: receiving, by the terminal device, at least one of the following from the network device: the first information, the first threshold, the restriction condition, and the new restriction condition.

[0198] It is worth noting that the above figures only schematically illustrate the embodiments of the present application, but the present application is not limited thereto. For example, the execution order between the operations can be appropriately adjusted, and in addition, some operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above description, and the present application is not limited to the description of the above figures.

[0199] The above embodiments are only illustrative of the embodiments of the present application, but the present application is not limited thereto, and can be appropriately modified on the basis of the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0200] According to the above embodiments, the terminal device receives first information indicating a priority of a logical channel when data available for transmission of the logical channel includes first data, and performs resource allocation on the logical channel according to the first information, thereby enhancing the priority of the logical channel in the logical channel priority processing. By enhancing the priority of the logical channel, it is helpful to reasonably allocate resources for the logical channel, thereby ensuring service performance and user experience.

[0201] Embodiments of the second aspect

[0202] The embodiments of the present application provide an information processing method, which is described from the terminal device side. The same content as the embodiments of the first aspect will not be described again.

[0203] FIG. 7 is a schematic diagram of an information processing method according to an embodiment of the present application. As shown in FIG. 7, the method includes the following steps.

[0204] 701, the terminal device selects a logical channel, and performs resource allocation on the selected logical channel.

[0205] In some embodiments, the terminal device does not limit the logical channel whose data available for transmission includes the first data by any limit condition when selecting the logical channel; or relaxes the limit of one or more limit conditions for the logical channel whose data available for transmission includes the first data when selecting the logical channel; or uses a new limit condition for the logical channel whose data available for transmission includes the first data when selecting the logical channel.

[0217] if a logical channel that does not contain the first data is configured with allowedPHY-PriorityIndex, and the configuration includes the priority index associated with the dynamic uplink grant;

[0218] if a logical channel that does not contain the first data is configured with allowedHARQ-mode, and the configuration includes the allowed uplink HARQ (Hybrid Automatic Repeat Request) mode associated with the uplink grant.

[0219] In some embodiments, the new restriction condition includes at least one of the following:

[0220] second information indicating a list of allowed subcarrier spacings when the logical channel contains the first data;

[0221] third information indicating a maximum PUSCH duration when the logical channel contains the first data;
