Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to an information processing method, apparatus, device, and computer-readable storage medium. Background Technology

[0002] To achieve more efficient communication, direct communication between terminals was introduced. For ease of description, the direct communication link between terminals is defined as a Sidelink link, and its corresponding wireless interface is called the direct communication interface (also known as the Sidelink interface); the cellular communication link between the network-side device and the terminal is called a Uu link link, and its corresponding interface is called the Uu interface. Figure 1 As shown, UE1 and UE2 communicate directly through the Sidelink link, and UE1 and UE2 communicate with the network-side equipment through the Uulink link.

[0003] For direct communication, in order for UE1 to know the channel quality of the direct communication interface between UE1 and UE2, UE2 needs to feed back CSI (Channel State Information) to UE1. The CSI is transmitted through CSI MAC (Media Access Control) CE (Control Element).

[0004] For CSI MAC CE, the physical layer introduces a latency limit. For direct communication interfaces, there is currently no clear solution in the technology for how to consider the latency limit of CSI MAC CE when performing direct communication interface scheduling. Summary of the Invention

[0005] This invention provides an information processing method, apparatus, device, and computer-readable storage medium to ensure that all transmissible CSI MAC CEs do not exceed their corresponding latency limits, thereby avoiding unnecessary CSI MAC CE transmissions.

[0011] If the direct communication interface needs to transmit both CSI MAC CE and logical channel data, then the CSI MAC CE that meets the first condition and the logical channel that meets the second condition are identified. All CSI MAC CE and logical channels that meet the conditions are compared in priority, and the first target with the highest priority is determined. The direct communication target address corresponding to the first target is then used as the direct communication target address.

[0012] Wherein, if the first target contains at least one CSI MAC CE, then the direct communication target address corresponding to the first target is used as the direct communication target address, including:

[0117] Figure 6 This is a structural diagram of the information processing device provided in an embodiment of the present invention. Detailed Implementation

[0118] The technical solutions of the embodiments of the present invention 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 the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0119] See Figure 2 , Figure 2 This is a flowchart of an information processing method provided in an embodiment of the present invention, applied to a terminal, such as... Figure 2 As shown, the method includes the following steps:

[0120] Step 201: (a) For a new data transmission resource of the direct communication interface, select the direct communication target address according to the CSI MAC CE of the direct communication interface; or, (b) For a new data transmission resource of the direct communication interface, if the TB of the new data resource transmission contains a CSI MAC CE, then make a packet dropping decision according to the contained CSI MAC CE.

[0121] Here, "new data transmission" refers to the first data transmission between direct communication terminals, and "new data transmission resources" refers to the resources used for the first data transmission.

[0122] For step 201(a), in this embodiment of the invention, the selection of the direct communication target address can be distinguished in the following cases:

[0123] Scenario 1: If only CSI MAC CE needs to transmit data on the direct communication interface, then select the highest priority CSI MAC CE from the CSI MAC CEs that meet the first condition as the first target, and use the direct communication target address corresponding to the first target as the direct communication target address.

[0124] Scenario 2: If the direct communication interface needs to transmit both CSI MAC CE and logical channel data, then the CSI MAC CE that meets the first condition and the logical channel that meets the second condition are identified. All CSI MAC CE and logical channels that meet the conditions are compared in priority, and the first target with the highest priority is determined. The direct communication target address corresponding to the first target is then used as the direct communication target address.

[0125] Since both CSI MAC CEs and logical channels have their own priorities, after determining the CSI MAC CEs that meet the first condition and the logical channels that meet the second condition, the priorities of the CSI MAC CEs and logical channels that meet the conditions can be compared.

[0126] The first condition includes: a timer starting at the CSI MAC CE trigger time, and the timer not timing out at the new data transmission time of the direct communication interface, wherein the length of the timer is equal to the CSI MAC CE delay limit; or, the difference between the new data transmission time of the direct communication interface and the CSI MAC CE trigger time is less than or less than or equal to the CSI MAC CE delay limit. The CSI MAC CE trigger time is the moment when the terminal receives the SCI including the CSI indication.

[0127] The second condition includes one or more of the following:

[0128] (1) If the new data transmission resource of the direct communication interface is a Type 1 pre-configured grant, then the LCP restriction parameter of the logical channel includes a Type 1 pre-configured grant;

[0129] (2) If the new data transmission resource of the direct communication interface is a pre-configured license, then the LCPrestriction parameter of the logical channel contains the number of the pre-configured license;

[0130] (3) The logical channel has data that can be transmitted;

[0131] (4) The number of available tokens in the token bucket corresponding to the logical channel is greater than 0.

[0132] In both of the above cases, if the first target contains at least one CSI MAC CE, then the direct communication target address corresponding to the first target can be used as the direct communication target address in any of the following ways:

[0133] (1) The terminal selects a target CSI MAC CE from at least one CSI MAC CE, and uses the direct communication target address corresponding to the target CSI MAC CE as the direct communication target address. For example, the terminal selects a target CSI MAC CE from at least one CSI MAC CE according to its own algorithm.

[0134] (2) For each CSI MAC CE, calculate the difference A1 between the CSI MAC CE trigger time and the new data transmission time of the direct communication interface, and calculate the difference A2 between the delay limit corresponding to the CSI MAC CE and A1, and select the direct communication target address corresponding to the CSI MAC CE with the smallest A2 as the direct communication target address. Wherein, the CSI MAC CE trigger time is the time when the terminal receives the SCI including the CSI indication.

[0135] (3) For each CSI MAC CE, determine the highest priority logical channel that belongs to the same target address as each CSI MAC CE and satisfies the second condition; compare the priorities of the highest priority logical channels selected for each CSI MAC CE to determine the target logical channel, and take the direct communication target address corresponding to the target logical channel as the direct communication target address.

[0136] For step 201(b), if the included CSI MAC CE satisfies the first condition, the TB is transmitted on the new data transmission resource of the direct communication interface; otherwise, the TB is discarded.

[0137] In this embodiment of the invention, the method for determining the latency limit of CSI MAC CE includes:

[0138] (1) Configured by network-side device. That is, the terminal receives configuration information from the network-side device, which is used to configure the latency limit of the CSI MAC CE, wherein the latency limit of the CSI MAC CE is configured according to any at least one method;

[0139] Based on terminal configuration;

[0140] Destination address configuration based on the terminal direct communication interface;

[0141] Source and destination address configuration based on the terminal direct communication interface;

[0142] Configuration based on destination address and transport type of the terminal direct communication interface

[0143] Configure the source address, destination address, and transport type based on the terminal direct communication interface.

[0144] In addition, the configuration information may also include at least one of the following:

[0145] The HARQ feedback configuration corresponding to the CSI MAC CE;

[0146] The priority of the CSI MAC CE;

[0147] The scheduling request resource configuration corresponding to the CSI MAC CE;

[0148] The HARQ feedback configuration is used to enable or disable HARQ feedback for the CSI MAC CE configuration.

[0149] The transmission types include unicast, multicast, and broadcast.

[0150] (2) As agreed upon by the protocol. That is, in this embodiment of the invention, the latency limit of the CSI MAC CE can be determined according to the protocol. The protocol may also stipulate at least one of the following information:

[0151] The HARQ feedback configuration corresponding to the CSI MAC CE;

[0152] The priority of the CSI MAC CE;

[0153] The scheduling request resource configuration corresponding to the CSI MAC CE;

[0154] The HARQ feedback configuration is used to enable or disable HARQ feedback for the CSI MAC CE configuration.

[0155] In this embodiment of the invention, when selecting the target address for direct communication or transmitting a transport block containing CSI MAC CEs in the physical layer, the latency limit of CSI MAC CEs needs to be considered for new data transmission resources of the direct communication interface. Thus, by using the solution of this embodiment of the invention, it can be ensured that all CSI MAC CEs transmitted by the direct communication interface meet the CSI MAC CE latency limit requirements, thereby avoiding unnecessary CSI MAC CE transmissions.

[0156] Based on the above embodiments, step 201(a) may further include:

[0157] For the selected direct communication target address, determine the CSIMAC CEs allowed to be transmitted within the direct communication target address, wherein the CSI MAC CEs allowed to be transmitted within the direct communication target address are triggered by the Direct Communication Interface Control Information (SCI) that schedules the direct communication target address, and satisfy at least one of the following conditions:

[0158] A timer is started at the CSI MAC CE trigger moment, and the timer has not timed out at the moment of new data transmission of the direct communication interface, wherein the length of the timer is equal to the delay limit of the CSI MAC CE;

[0159] The difference between the new data transmission time of the direct communication interface and the CSI MAC CE trigger time is less than or equal to the CSI MAC CE delay limit.

[0160] The CSI MAC CE trigger time is the moment when the terminal receives the SCI including the CSI indication.

[0161] Based on the above embodiments, resource allocation can also be performed. Specifically, when allocating resources within the direct communication target address, the first round of resource allocation is performed in descending order of priority of CSI MAC CE and / or logical channels; wherein, in the first round of resource allocation, resource allocation for logical channels is subject to the PBR restriction of logical channels, while resource allocation for CSI MAC CE is not subject to the PBR restriction.

[0162] If there are still resources remaining after the first round of resource allocation, the second round of resource allocation will be carried out in descending order of logical channel priority, until resources are exhausted or all logical channels have been allocated resources.

[0163] In this embodiment of the invention, when selecting the destination at the MAC layer or transmitting data blocks containing CSI MAC CE at the physical layer for new data transmissions scheduled via SCI (Sidelink Control Information), the transmission latency limitations of CSI MAC CE need to be considered. The implementation process of the information processing method of this invention is described in detail below with reference to different embodiments.

[0164] See Figure 3 , Figure 3 This is a flowchart of the information processing method provided in an embodiment of the present invention. Figure 3 The following example illustrates how the MAC layer considers the CSI MAC CE latency bound when selecting a target address. Figure 3 As shown, the method includes the following steps:

[0165] Step 301: For the new data transmission resource of the direct communication interface, select the direct communication target address to be transmitted.

[0166] This step is performed at the MAC layer and is part of the MAC LCP (Logical Channel Prioritization) process.

[0167] If the currently transmittable data includes CSI MAC CE, then the latency bound of the CSI MAC CE needs to be considered. That is, a CSI MAC CE that meets the condition should be selected based on the latency bound of the CSI MAC CE. The specific selection method can be one of the following:

[0168] Method 1: A timer is started at the CSI MAC CE trigger time. The length of the timer is equal to the latency bound corresponding to the CSI MAC CE. When selecting a destination at the MAC layer, if the timer corresponding to the CSI MAC CE has not expired at the transmission time indicated by the SCI, then the CSI MAC CE is determined to be a CSI MAC CE that meets the conditions.

[0169] Method 2: For new data transmissions scheduled by SCI, determine the time difference between the transmission time indicated by SCI and the trigger time of each currently pending CSI MAC CE. If the time difference corresponding to a certain CSI MAC CE is less than or equal to the latency bound corresponding to that CSI MAC CE, then that CSI MAC CE is determined to be a CSI MAC CE that meets the conditions.

[0170] The latency bound of CSI MAC CE can be determined in two ways:

[0171] Method 1: Determined based on network configuration, which may include the following:

[0172] Method 1.1: Latency bound is based on UE configuration;

[0173] Method 1.2, latency bound configuration based on the destination address of the UE's direct communication interface;

[0174] Method 1.3, latency bound configuration based on the combination of source and destination addresses of the UE's direct communication interface;

[0175] Method 1.4, latency bound configuration based on the combination of UE direct communication interface destination address and cast type (transmission type);

[0176] Method 1.5, latency bound, is a configuration based on the combination of source address, destination address, and cast type of the UE direct communication interface.

[0177] Method 2: As agreed upon in the agreement, that is, the latency bound corresponding to CSI MAC CE is directly agreed upon in the agreement.

[0178] The CSI MAC CE is triggered when the terminal receives an SCI containing a CSI indication.

[0179] Furthermore, the MAC selects the highest priority CSI MAC CE or logical channel from the CSI MAC CE and logical channels that meet the conditions, and then uses the direct communication interface destination corresponding to the selected CSI MAC CE or logical channel as the target destination.

[0180] The priority of CSI MAC CE is determined as follows: When configuring CSI MAC CE in the network, the priority of CSI MAC CE is configured in the configuration information. Alternatively, the protocol stipulates the priority of CSI MAC CE, for example, always being 1.

[0181] If there are multiple highest-priority CSI MAC CEs, the specific method for selecting the direct communication target address corresponding to the CSI MAC CE as the direct communication target address is as follows:

[0182] Method 1: Depending on the implementation of the direct communication terminal, select the CSI MAC CE from multiple highest priority CSI MAC CEs.

[0183] Method 2: For each CSI MAC CE, calculate the difference A1 between the CSI MAC CE trigger time and the new data transmission time of the direct communication interface, and calculate the difference A2 between the delay limit corresponding to the CSI MAC CE and A1, and select the CSI MAC CE with the smallest A2.

[0184] Method 3: For each CSI MAC CE, determine the highest priority logical channel that belongs to the same target address as each CSI MAC CE and meets certain conditions. Compare the priorities of the highest priority logical channels selected for each CSI MAC CE to determine the target logical channel, and select the CSI MAC CE that belongs to the same direct communication target address as the target logical channel.

[0185] The conditions that the above logical channels need to meet include, but are not limited to, one or a combination of the following:

[0186] The logical channel has data that can be transmitted;

[0187] The number of available tokens in the token bucket corresponding to the logical channel is greater than 0 (Bj>0);

[0188] If the resource used for new data transmission is a Type 1 pre-configured license, then the configuredSLGrantType1Allowed parameter in the LCPrestriction parameter corresponding to the logical channel needs to be set to allowed;

[0189] If the resource used for new data transmission is a pre-configured grant, then the pre-configured grant list configured in the LCPrestriction parameter corresponding to the logical channel needs to include the number of the pre-configured grant.

[0190] Step 302: For the selected direct communication target address, determine the allowed logical channel and CSI MACCE.

[0191] The direct communication terminal will use logical channels belonging to the target address and meeting the following conditions as allowed logical channels for data transmission:

[0192] The logical channel has data that can be transmitted;

[0193] If the resource used for new data transmission is a Type 1 pre-configured license, then the configuredSLGrantType1Allowed parameter in the LCPrestriction parameter corresponding to the logical channel needs to be set to allowed;

[0194] If the resource used for new data transmission is a pre-configured grant, then the pre-configured grant list configured in the LCPrestriction parameter corresponding to the logical channel needs to include the number of the pre-configured grant;

[0195] The HARQ feedback configuration of a logical channel is the same as the highest priority CSI MAC CE within its target address or the HARQ feedback configuration of the logical channel.

[0196] The direct communication terminal will designate a CSI MAC CE belonging to the target address and meeting one of the following conditions as an allowed CSI MAC CE for transmission:

[0197] Condition 1: When the CSI MAC CE is triggered, a timer is started. The length of the timer is equal to the latency bound corresponding to the CSI MAC CE. The timer has not timed out when the MAC PDU (Protocol Data Unit) is transmitted.

[0198] Method 2: For CSI MAC CE, determine the difference between the transmission time of its corresponding MAC PDU and its trigger time, wherein the difference is less than or less than or equal to the latency bound corresponding to the CSI MAC CE.

[0199] Step 303: Perform the first round of resource allocation for the logical channels that are allowed to be transmitted for the selected direct communication target address.

[0200] The first round of resource allocation is performed for the logical channel and CSI MAC CE selected in step 302. When allocating resources for the logical channel and CSI MAC CE within a direct communication target address, resources are allocated to the CSI MAC CE in the first round of resource allocation, and the CSI MAC CE resource allocation is not subject to PBR restrictions. For other logical channels, resources are allocated in descending priority order and according to PBR requirements in the first round of resource allocation.

[0201] Step 304: Perform a second round of resource allocation for the logical channels that are allowed to transmit for the selected direct communication target address.

[0202] If there are still resources remaining after the first round of resource allocation in step 303, resources are allocated to the remaining data volume of the logical channels allowed to be transmitted within the direct communication target address in descending order of logical channel priority, until the resources are exhausted or all logical channels have been allocated resources.

[0203] Generate MAC PDU based on resource allocation results.

[0204] Step 305: Indicate the HARQ feedback indication of the SCI corresponding to the MAC PDU to the physical layer.

[0205] If the highest priority CSI MAC CE in the MAC PDU is determined, then the HARQ feedback indication in the SCI is determined according to the HARQ feedback configuration corresponding to the CSI.

[0206] The specific method for determining the HARQ feedback configuration corresponding to the CSI is as follows:

[0207] When configuring the latency bound of CSI MAC CE, the network-side device further includes the HARQ feedback configuration corresponding to CSI MAC CE in the configuration information. The HARQ feedback configuration is the setting to enable or disable HARQ feedback for CSI MAC CE.

[0208] When the protocol specifies the latency bound corresponding to CSI MAC CE, it also specifies the HARQ feedback configuration corresponding to CSI MAC CE, that is, enabling / disabling HARQ feedback for CSI MAC CE configuration.

[0209] See Figure 4 , Figure 4 This is a flowchart of the information processing method provided in an embodiment of the present invention. Figure 4The following description uses the latency bound constraint of CSI MAC CE when transmitting data blocks at the physical layer as an example. Figure 4 As shown, the method includes the following steps:

[0210] Step 401: Generate MAC PDU.

[0211] When the MAC layer selects a direct communication target address, it selects the direct communication target address corresponding to the highest-priority CSI MAC CE or logical channel based entirely on the CSI MAC CE and logical channel priority. Then, it allocates resources to the CSI MAC CE and eligible logical channels within that direct communication target address. The determination of eligible logical channels can be found in [reference needed]. Figure 3 The example shown.

[0212] Step 402: Submit the MAC PDU to the physical layer.

[0213] Step 403: During physical layer data transmission, a packet discard decision is made based on the transmission delay of CSI MAC CE.

[0214] If the MAC PDU contains a CSI MAC CE, the physical layer needs to consider the latency bound of the CSI MAC CE when performing data transmission. Specifically, after receiving a MAC PDU with a MAC indication, if the MAC PDU contains a CSI MAC CE, the physical layer discards the MAC PDU if one of the following conditions is met:

[0215] Condition 1: A timer is started when the CSI MAC CE is triggered. The length of the timer is equal to the latency bound corresponding to the CSI MAC CE. The timer has expired when the MAC PDU is transmitted.

[0216] Method 2: For CSI MAC CE, determine the difference between the transmission time of its corresponding MAC PDU and its trigger time, where the difference is greater than the latency bound corresponding to the CSI MAC CE.

[0217] The CSI MAC CE trigger time is the moment when the terminal receives the SCI containing the CSI indication.

[0218] As can be seen from the above description, the embodiments of the present invention can ensure that all CSI MAC CEs transmitted through the direct communication interface meet the CSI MAC CE latency bound requirement, thus avoiding unnecessary CSI MAC CE transmissions.
