Description

Resource indication method and device

Technical field

Embodiments of the present application relate to the field of communications, and in particular, to a method and an apparatus for resource indication.

Background technique

At present, the fourth-generation communication system, the long-term evolution-advanced system (LTE-A), will continue to provide wireless communication services for user equipment (UE) in the short term (or even the long term). In particular, enhanced machine type communication (eMTC) systems and other evolutionary systems, such as (further eMTC, FeMTC); (evenfurther eMTC, eFeMTC); (additional MTC, AMTC) are based on LTE Derived system. For the above-mentioned machine type communication, the communication interval of some services is relatively long, and the communication data packets are small. In order to achieve energy saving and reduce signaling overhead, LTE release-16 decided to standardize the transmission mechanism on predefined resources, that is, to communicate directly without the need for dynamic downlink control information (DCI) scheduling. Therefore, it is also called a scheduling-free transmission or a configured (granted) transmission. At present, there is a need to standardize the scheduling-free transmission in the connected state and the idle state. For scheduling-free transmission, its time-frequency resources are defined in advance, so users can directly transmit data on the predefined time-frequency resources when a data packet arrives.

These scheduled grant-free (GF) time-frequency resources can only be used by a specific terminal (or terminal group) for scheduling-free transmission. Since the base station does not know whether any terminal uses these reserved resources for transmission, no matter whether the terminal uses these resources, it must reserve this part of the time-frequency resources. This results in that these time-frequency resources can only be idle when the terminal has no data transmission, which causes a certain degree of waste. For the connection-free scheduling-free transmission, activation and deactivation of pre-defined time-frequency resources may be performed through special radio resource control (radio resource control (RRC) signaling) and / or DCI. However, for idle users, there is no specific RRC signaling to activate or deactivate pre-defined GF (grant-free) time-frequency resources; nor does it have user-specific DCI to activate and deactivate. That is, when the terminal is in an idle state, there is no corresponding method for activating and deactivating the GF time-frequency resource of the terminal.

Summary of the Invention

Embodiments of the present application provide a resource indication method and apparatus, which are used to activate and deactivate transmission resources corresponding to the user equipment when the terminal is in an idle state, thereby improving resource utilization.

A first aspect of the embodiments of the present application provides a resource indication method, including: the base station determining first indication information, where the first indication information is used to instruct a terminal to send an uplink signal on a transmission resource (that is, to activate the transmission resource) or not An uplink signal is sent on the transmission resource (that is, the transmission resource is deactivated), where the terminal is in a non-connected state; then the base station sends the first indication information to the terminal, so that the terminal can according to the first indication information Whether to implement uplink signal transmission on the transmission resource. The activation or enabling of the transmission resource described in this application is equivalent to instructing the terminal to transmit an uplink signal on the transmission resource. Deactivating or deactivating the transmission resource and instructing the terminal not to transmit an uplink signal on the transmission resource are equivalent. equivalent.

Optionally, the first indication information may also be used to instruct the terminal to perform early data transmission (Early Data Transmission); and / or, the first indication information is used to instruct the terminal to perform a random access procedure (Random Access procedure) And / or, the first indication information is used to instruct the terminal to send a preamble; and / or the first indication information is used to notify the terminal of a timing advance TA (timing advance) parameter; and / or, the The first indication information is used to notify the terminal of a power control parameter. The timing advance parameter may be an adjustment amount (or index) to advance at a specified time or an absolute amount (or index) to advance in timing. The power control parameter may be an adjustment amount (or index) of power or a step size (or index) of power control adjustment. The adjustment amount refers to the increase or decrease based on the current timing advance or power value, and the absolute amount is the advance value at the time of designation and the amount determined by the instruction.

Optionally, the base station may determine whether to generate the first indication information according to a load condition and / or a service characteristic of a transmission resource in the current system. For example, the base station does not generate the first indication information when the load condition of the transmission resource is greater than a preset threshold; or the base station generates the first indication information when the load condition of the transmission resource is less than or equal to the preset threshold. It can be understood that this is only an example of a possible implementation manner, as long as the utilization rate of transmission resources can be improved and the transmission efficiency is satisfied, the specific manner is not limited here.

Optionally, before the base station determines the first indication information, the base station may further obtain status information of a transmission resource corresponding to the terminal, and determine the first information according to the status information and a load condition and / or a service characteristic of the transmission resource. An instruction message. For example, if the status information of the transmission resource indicates that the terminal can use the transmission resource to send an uplink signal, and the load condition of the transmission resource is greater than a threshold, the base station determines the first indication information, and the first indication information is used to indicate the The terminal cannot use the transmission resource to send an uplink signal (that is, deactivate); if the status information of the transmission resource indicates that the terminal can use the transmission resource to send an uplink signal, and the load condition of the transmission resource is less than or equal to a threshold (that is, the base station The terminal needs to be notified that the transmission resource can be used to send an uplink signal. At this time, the base station may not generate the first indication information or the base station may not send the first indication information to the terminal. This can effectively reduce the communication instruction between the base station and the terminal, and improve the effectiveness of the instruction.

In this embodiment, the base station may indicate the status of the transmission resource of the terminal by sending instruction information to the terminal in the idle state, so that the terminal can activate and deactivate the transmission resource in the idle state.

The terminal identifier. If it does not exist, the terminal does not perform operations. If it does, the terminal may further read the first instruction information from the paging message, and perform a corresponding operation according to the first instruction information. It can be understood that the terminal identity may be a temporary mobile subscriber identity (SAE) (system architecture-temporary mobile-station identifier) (S-TMSI) or an international mobile subscriber identity (IMSI), or a cell wireless network Cell-radio network temporary identifier (C-RNTI). At the same time, the terminal identifier can also be related to the demodulation reference signal (DMRS) when the terminal sends an uplink signal. It can be understood that the search The call message may be a paging message. Therefore, the first indication information may also be carried in a Paging record in the paging message.

When the DCI format 6-2 carries the first indication information, the DCI format 6-2 may be a DCI format 6-2 scrambled by a paging-radio network temporary identity (P-RNTI) And the flag of the DCI format 6-2 is 0. At the same time, in this case, the first indication information is located in the direct indication information (Direct Indication Information) in the DCI format 6-2, such as the 6th, 7th, or 8th bit, or other unused bits.

Specifically, when the terminal needs to send an uplink signal on the transmission resource, the first RNTI scrambles the MPDCCH, and then the terminal sends or does not send the uplink signal through the MPDCCH scheduling or configuration information.

In the above several ways, the first indication information may be expressed by one bit of information.

Similarly, when receiving and sending the first information between the terminal and the base station, the period needs to be ensured to be the same.

Optionally, the first instruction information may also be used to instruct the terminal to perform early data transmission (Early Data Transmission); and / or, the first instruction information is used to instruct the terminal to perform random access procedure (Random Access Procedure).

detailed description

The terms "first", "second", "third", "fourth", and the like (if present) in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and need not be used For describing a particular order or sequence. It should be understood that the data used in this way are interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than what is illustrated or described herein. Furthermore, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units need not be limited to those explicitly listed Those steps or units may instead include other steps or units not explicitly listed or inherent to these processes, methods, products or equipment.

The following explains some terms in this application document, so that those skilled in the art can understand:

1. For the three states of the UE in the communication system: according to the connection state of the UE and the core network, the state where the UE is located can be divided into an idle state, an inactive state, and a connected state. When the UE is in a connected state, the UE can directly communicate with the base station and transmit data. When the UE is in an idle state, if the UE needs to transmit data, the UE needs to perform random access first, and then can perform data transmission after establishing an RRC connection with the base station. When the UE is in the inactive state, both the UE and the core network side retain the context of the RRC message when the UE is in the connected state. If the UE needs to transmit data, the UE can access the connection state faster according to the context of the reserved RRC message, thereby implementing data transmission.

2. Paging message: A paging message sent by a base station or core network device to a UE. The UE may be in an idle state or a connected state. The paging message may be sent by the base station triggered by the core network, or triggered by the base station.

3. Timing advance (TA): In order to reach the base station with the uplink data packet within the expected time during uplink transmission, the UE sends the data packet in advance according to the estimated transmission delay. The corresponding time in advance here is called Be ahead of time.

4. Scheduling-free transmission: In order to achieve energy saving and reduce signaling interaction overhead in machine-type communications, LTE release-16 decided to standardize the transmission mechanism on predefined resources, that is, direct data transmission without dynamic DCI scheduling. Therefore, it is also called schedule-free transmission.

For scheduling-free transmission, its time-frequency resources are defined in advance, so users can directly transmit data on the predefined time-frequency resources when a data packet arrives. An application scenario thereof may be shown in FIG. 1. The base station communicates with the UE. The base station configures UE1 therein with scheduling-free time-frequency resources. Therefore, the scheduling-free time-frequency resources can only be used by UE1 for scheduling-free transmission. Because the base station does not know whether UE1 uses these reserved resources for transmission, regardless of whether UE1 uses these resources, it must reserve this part of the time-frequency resources. This results in that these time-frequency resources can only be idle when UE1 has no data transmission, which causes a certain degree of waste. Therefore, the base station needs to implement activation and deactivation of the predefined scheduling-free resource. Currently, for a user equipment in a connected state, activation and deactivation of a predefined schedule-free time-frequency resource can be performed and deactivated through a unique RRC signaling and / or DCI. However, for the user equipment in idle state, there is no specific RRC signaling to activate or deactivate the predefined scheduling-free time-frequency resource; nor is there any specific DCI to activate and deactivate the predefined scheduling-free time-frequency resource. . That is, when the user equipment is in an idle state, the scheduling-free time-frequency resources of the user equipment have no corresponding activation and deactivation methods.

In order to solve this problem, an embodiment of the present application provides the following method: When the base station determines that the scheduling-free time-frequency resource of the UE in an idle state needs to be operated, the base station generates corresponding indication information, where the indication information is used to instruct the UE Perform a corresponding operation on the scheduling-free time-frequency resource that belongs to itself; then, the base station sends the instruction information to the UE, so that the UE performs a corresponding operation on the scheduling-free time-frequency resource that belongs to it according to the instruction information.

For details, please refer to FIG. 2, which is an embodiment of a resource processing method according to an embodiment of the present application:

201. The base station determines first indication information, where the first indication information is used to indicate that the terminal can send an uplink signal on a transmission resource or cannot send an uplink signal on the transmission resource, and the terminal is in a non-connected state.

The base station may determine whether to generate the first indication information according to a load condition and / or a service characteristic of a transmission resource in the current system. For example, the base station does not generate the first indication information when the load condition of the transmission resource is greater than a preset threshold; or the base station generates the first indication information when the load condition of the transmission resource is less than or equal to the preset threshold. It can be understood that this is only an example of a possible implementation manner, as long as the utilization rate of transmission resources can be improved and the transmission efficiency is satisfied, the specific manner is not limited here.

In this embodiment, the transmission resource is a scheduling-free transmission resource, that is, the transmission resource is a transmission resource preset configured by the base station for the terminal or a scheduling-free transmission resource configured by the base station for the terminal through scheduling information. The transmission resources pre-configured here or the transmission resources configured by the scheduling information configured between the base station and the terminal refer to resources that do not require dynamic downlink control information (DCI) configuration. The transmission resource includes at least the following types of information: time resources, frequency resources, repetition times, frequency hopping modes, time periods, and transmission power.

202. The base station sends the first indication information to the terminal.

The base station sends the first indication information to the terminal.

Optionally, when the base station sends the first indication information to the terminal, the first indication information may be broadcast to the terminal as a data packet; the first indication information may also be carried in a paging message or downlink control information. (downlink control information, DCI) format 6-2, and then the base station sends the paging message or DCI format 6-2; the first indication information may also be carried in the system information and sent to the terminal; or the first An indication message is carried in the first message and sent to the terminal through a dedicated channel.

Optionally, when the paging message or the first information carries the first indication information, a terminal identifier list may also be carried, so that the terminal may determine whether the terminal itself exists according to the terminal identifier list after receiving the paging message. If the terminal ID does not exist, the terminal does not perform operations. If it exists, the terminal may further read the first instruction information from the paging message, and perform a corresponding operation according to the first instruction information. It can be understood that the terminal identity may be a temporary mobile subscriber identity (SAE) (system architecture-temporary mobile-station identifier) (S-TMSI) or an international mobile subscriber identity (IMSI), or a cell wireless network Cell-radio network temporary identifier (C-RNTI). At the same time, the terminal identifier can also be related to the demodulation reference signal (DMRS) when the terminal sends an uplink signal. It can be understood that the search The call message may be a paging message. Therefore, the first indication information may also be carried in a Paging record in the paging message.

When the DCI format 6-2 carries the first indication information, the DCI format 6-2 may be a DCI format format scrambled by a paging-radio network temporary identifier (P-RNTI) 6- 2, and the flag of the DCI format 6-2 is 0. At the same time, in this case, the first indication information is located in the direct indication information in the DCI format 6-2, such as the 6th, 7th, or 8th bit, or it can also be expressed by other unused bits, specifically carried The form is not specifically limited.

203. The terminal performs a corresponding operation according to the first instruction information.

In this embodiment, when the terminal receives the first indication information, the terminal may receive the first indication information sent by the base station according to a preset paging cycle, wherein the cycle at which the base station sends the first indication information is the same as that received by the terminal. The paging cycle of the first indication information is the same, ensuring that the terminal can receive the first indication information sent by the base station.
