Description

A method and device for configuring scheduling parameters

Technical Field

The present invention relates to the field of wireless communication technology, and in particular to a method and device for configuring scheduling parameters.

Background Art

The 5G NR (New Radio) standard introduces a configured grant (or Grant-free) uplink transmission mechanism. Different from the transmission mode based on DCI (Downlink Control Information) dynamic scheduling, in the configured or free uplink transmission, when the terminal wants to send data, it can directly transmit on the pre-configured resources without sending a scheduling request to the base station and waiting for the base station's authorization information.

The transmission mode can be orthogonal or non-orthogonal, depending on the service type and the number of users transmitting simultaneously. Non-orthogonal multiple access technology has received widespread attention, and the 3GPP (3rd Generation Partnership Project) standard is currently discussing related issues. The configuration scheduling or scheduling-free transmission mechanism combined with non-orthogonal multiple access technology can serve more users on the same frequency resources at the same time, improving spectrum efficiency. In the existing configuration scheduling or scheduling-free uplink transmission, some parameters required for transmission are configured by RRC (Radio Resource Control) signaling, but other parameters required for scheduling do not specify how to configure them.

In summary, in the existing configuration scheduling or scheduling-free uplink transmission, some parameters do not specify how to configure them.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The following are explanations of some of the terms that appear in the text:

1. The “terminal” referred to in the embodiments of the present invention refers to a terminal that can support the scheduling parameter configuration, that is, a mobile phone, a tablet, a computer, etc.

2. The “network side device” referred to in the embodiments of the present invention is a base station or other device that can perform parameter configuration for a terminal, such as a macro base station, a home base station, etc.

3. In the embodiments of the present application, the term "and/or" describes the association relationship of the associated objects, indicating that there may be three relationships. For example, A and/or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character "/" generally indicates that the associated objects before and after are in an "or" relationship.

The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 1 , the system for binding devices according to the embodiment of the present invention includes: a network-side device 10 and a terminal 20 .

The network side device 10 is used to send first information for determining a transmission mode and/or second information for determining an MA codeword to a terminal through RRC signaling.

The terminal 20 is used to receive, through RRC signaling, first information for determining a transmission mode sent by a network side device and second information for determining an MA codeword.

In an embodiment of the present invention, a network side device sends first information for determining a transmission mode and/or second information for determining an MA codeword to a terminal through RRC signaling, and the terminal receives the first information for determining a transmission mode and/or second information for determining an MA codeword sent by the network side device through RRC signaling. Since the configuration of the user transmission mode and the MA codeword through RRC signaling is implemented in the embodiment of the present invention, when the terminal wants to send data, it can directly transmit on the preconfigured resources without sending a scheduling request to the network side device and waiting for the authorization information of the network side device, thereby reducing the complexity of the system.

The configuration of the first information and the second information are introduced below respectively.

Configuration 1. Configure the first information.

Optionally, when the network side device sends the first information for determining the transmission mode to the terminal through RRC signaling, the first information may be placed at any position in the RRC signaling, such as the network side device placing the first information in an information unit of the RRC signaling. The first information includes: information for indicating an orthogonal mode and/or information for indicating a non-orthogonal mode.

The fields added in the information unit of the RRC signaling include, but are not limited to, some or all of the following:

Characters, strings, numbers, identifiers.

Optionally, the information unit is ConfiguredGrantConfig.

In implementation, information for configuring the user's transmission mode as orthogonal or non-orthogonal may be added in advance to the ConfiguredGrantConfig of the RRC signaling.

Correspondingly, the terminal obtains the first information from the ConfiguredGrantConfig of the RRC signaling, and determines the transmission mode according to the first information. For example, an MA mode field is added to the ConfiguredGrantConfig to indicate whether the transmission mode is orthogonal or non-orthogonal.

OMA stands for orthogonal and NoMA stands for non-orthogonal. If MAmode is OMA in the ConfiguredGrantConfig configuration, the user uses the orthogonal transmission mode in the configuration scheduling or scheduling uplink transmission. If MA mode is NOMA in the ConfiguredGrantConfig configuration, the user uses the non-orthogonal transmission mode in the configuration scheduling/non-scheduling uplink transmission.

Optionally, after the network side device sends the first information for determining the transmission mode to the terminal through RRC signaling, the network side device also updates the transmission mode determined according to the first information and sent to the terminal through MAC CE.

During transmission, if the user's transmission mode changes, the network side device will update the user's transmission mode through MAC CE;

Correspondingly, the terminal determines the transmission mode updated by the network side device through MAC CE and updates it.

For example, when the terminal receives an update of the first information by MAC CE and updates the transmission mode to NoMA, the user uses the non-orthogonal transmission mode for subsequent transmission after the MAC CE takes effect.

Configuration 2: Configure the second information.

Optionally, when the network side device sends the second information for determining the MA codeword to the terminal through RRC signaling, the second information may be placed at any position in the RRC signaling, for example, the network side device places the second information in an information unit of the RRC signaling.

Optionally, the information unit is ConfiguredGrantConfig.

The second information includes: configuration information of the MA codeword or the DMRS bound to the MA codeword.

When configuring the user's MA codeword, you can configure it in explicit mode or implicit mode, which is described in detail below.

Method 1: Display configuration method.

When the network side device sends the second information for determining the MA codeword to the terminal through RRC signaling, the second information may be placed at any position in the RRC signaling, for example, the network side device places the second information in the ConfiguredGrantConfig of the RRC signaling.

The second information is configuration information of the MA codeword.

The form of the domain added in the ConfiguredGrantConfig of the RRC signaling includes but is not limited to part or all of the following:

Characters, strings, numbers, identifiers.

In implementation, the configuration information field of the MA codeword may be added in advance to the ConfiguredGrantConfig of the RRC signaling.

Correspondingly, the terminal obtains the second information from the ConfiguredGrantConfig of the RRC signaling, and determines the MA codeword according to the second information.

Optionally, after the network side device sends the second information for determining the MA codeword to the terminal through RRC signaling, the network side device also determines and updates the MA codeword updated by the network side device through MAC CE. During transmission, if the MA codeword of the user changes, the network side device updates the MA codeword of the user through MAC CE;

Correspondingly, the terminal determines the MA codeword updated by the network side device through the MAC CE and updates it.

For example, in the ConfiguredGrantConfig configuration, the MA signature is s1, and the user uses the MA signature corresponding to s1 for transmission in the configuration scheduling or unscheduled uplink transmission. When the terminal receives the MAC CE to determine the MA codeword updated by the network side device, the MA codeword is updated and the MA signature is updated to s2. Then, after the MAC signaling takes effect, the user uses the MAsignature corresponding to s2 for transmission.

Method 2: Implicit configuration method.

When the network side device sends the second information for determining the MA codeword to the terminal through RRC signaling, the second information may be placed at any position in the RRC signaling, for example, the network side device places the second information in the ConfiguredGrantConfig of the RRC signaling.

The second information is the DMRS bound to the MA codeword, and the binding relationship between the MA codeword and the DMRS can be pre-agreed by the network side device and the terminal, or can be notified to the terminal by the network side device through RRC signaling or other signaling. In the embodiment of the present invention, the DMRS can be configured through RRC signaling to realize implicit configuration of the MA codeword.

DMRS includes but is not limited to part or all of the following:

DMRS Type, maxLength, antenna port, dmrs-SeqInitialization.

In implementation, the network side device may place the second information in the ConfiguredGrantConfig of the RRC signaling in advance.

Correspondingly, the terminal obtains the second information from the ConfiguredGrantConfig of the RRC signaling to determine the DMRS of the user, and then determines the MA codeword of the user through the binding relationship between the DMRS and the MA codeword.

The user's MA codeword information is not directly reflected in the configuration process, but the implicit configuration of the user's MA codeword is realized through the configuration of DMRS. For example, ConfiguredGrantConfig already includes the DMRS type, symbol length and other configurations. The antenna port, dmrs-SeqInitialization and other configurations related to DMRS are configured through RRC in the Type 1 configuration scheduling or scheduling-free transmission. The specific form of the relevant domain is as follows:

Optionally, after the network side device sends the second information for determining the transmission mode MA codeword to the terminal through RRC signaling, the network side device also updates the second information sent to the terminal through RRC signaling or MAC CE.

During transmission, if the user's DMRS changes, the network side device will update the user's DMRS through signaling;

Correspondingly, the terminal updates the second information through the received signaling.

When updating the user's DMRS, it can be updated through RRC signaling or MAC CE, which is described in detail below.

Method 1: Update DMRS through RRC signaling.

Specifically, during transmission, the user's DMRS changes, and the network side device updates the user's DMRS through RRC signaling. Correspondingly, the terminal updates the second information through the received RRC signaling, and then completes the update of the user's MA codeword through the mapping relationship between DMRS and MA codeword.

For example, if the DMRS antenna port is 1 in the ConfiguredGrantConfig configuration, the user uses the DMRS-bound MA codeword with the DMRS antenna port of 1 for transmission in the configured scheduled or unscheduled uplink transmission. When the terminal receives the update of the second information by RRC signaling, the DMRS antenna port is updated to 2. Then, after the RRC signaling effective time, the user uses the DMRS-bound MA codeword with the DMRS antenna port of 2 for transmission.

Method 2: Update DMRS through MAC CE.

Specifically, during transmission, the user's DMRS changes, and the network side device updates the user's DMRS through MAC CE. Correspondingly, after the terminal receives the MAC CE updated DMRS configuration, it uses the updated configuration to transmit DMRS after the MAC CE takes effect, and updates the MA codeword corresponding to the DMRS.

For example, if dmrs-SeqInitialization is 0 in the ConfiguredGrantConfig configuration, the user uses the DMRS-bound MA codeword with dmrs-SeqInitialization of 0 for transmission in the configured scheduled or unscheduled uplink transmission. When the terminal receives the MAC signaling to update the second information, the dmrs-SeqInitialization is updated to 1. Then, after the RRC signaling effective time, the user uses the DMRS-bound MA codeword with dmrs-SeqInitialization of 1 for transmission.

It should be noted that the updating method of the second information in the embodiment of the present invention is only an example, and any method of updating the second information is applicable to the present invention.

In implementation, if the second information includes configuration information of multiple MA codewords, the network side device notifies the terminal of the configuration information of the MA codeword to be used through the MACCE, and the terminal determines the configuration information of the MA codeword to be used notified by the network side device through the MAC CE;

Optionally, the network side device places the second information including the configuration information of multiple MA codewords in the ConfiguredGrantConfig of the RRC signaling and sends it to the terminal. The network side device notifies the terminal of the configuration information of the MA codewords to be used through the MAC CE, and the terminal determines the configuration information of the MA codewords to be used notified by the network side device through the MAC CE.

as follows:

Among them, s1, s2, ..., sn is the second information of the configuration information of multiple MA codewords contained in the MAsignature in the ConfiguredGrantConfig of the RRC signaling. If the configuration information of the MA codeword that the terminal needs to use is s2, then the network side device notifies the terminal through the MAC CE that the configuration information of the MA codeword to be used is s2, and the terminal determines through the MAC CE that the configuration information of the MA codeword to be used notified by the network side device is s2.

In implementation, if the second information includes multiple DMRSs bound to MA codewords, the network side device notifies the terminal of the DMRS to be used through MAC CE, and the terminal determines the DMRS to be used notified by the network side device through MAC CE.

Specifically, the network side device places the second information including multiple DMRS bound to the MA codeword in the RRC signaling and sends it to the terminal. The network side device notifies the terminal of the DMRS bound to the MA codeword that needs to be used through the MAC CE, and the terminal determines the DMRS bound to the MA codeword that needs to be used notified by the network side device through the MAC CE.

It should be noted that the embodiments of the present invention are all examples of the situation in which the network side device determines one of the multiple second information that the terminal needs to use, and any situation in which the network side device determines one of the multiple second information that the terminal needs to use is applicable to the present invention.
