Patent Description:
The uplink of the Uu interface between a terminal and a network device supports two resource allocation modes: configured grant and dynamic scheduling, wherein the configured grant refers to resources that are pre-allocated by the network side to the terminal and do not need to be dynamically scheduled. For the Uu interface between the terminal and the network device, a cell currently only supports one set of uplink configured grants. The allocation of uplink configured resources of the Uu interface is divided into two types, which are called Configured Grant Type <NUM> and Configured Grant Type <NUM>.

The configured grant type <NUM> means that the base station assigns specific uplink resources to the terminal through the RRC (Radio Resource Control) signaling, including the resource period, corresponding CS-RNTI (Configured Scheduling-Radio Network Temporary Identity), time-frequency resource position, specific transmission format (such as MCS (Modulation and Coding Scheme)), etc. As shown in <FIG>, the terminal obtains the periodic uplink transmission resources according to the RRC control signaling, and can immediately transmit the uplink data according to the allocated periodic uplink transmission resources. In the logical channel configuration, it is also possible to configure whether the logical channel can use the resources of the configured grant type <NUM>.

The configured grant type <NUM> refers to the period during which the base station allocates periodic uplink transmission resources to the terminal through the RRC signaling and the CS-RNTI. As shown in <FIG>, the base station subsequently activates or deactivates the configured resources of the configured grant type <NUM> through the PDCCH (Physical Downlink Control Channel) command, and the base station indicates the specific transmission resources (including time-frequency resources, transmission format, etc.) in the PDCCH command of activating the configured grant type <NUM>.

For the NR (New Radio) direct communication interface, a BWP (Bandwidth Part) can be allowed to support one or more sets of configured resources, and the NR direct communication interface also supports two configured grants: configured grant type <NUM> and configured grant type <NUM>. For the configured grant type <NUM>, the configured resources need to be activated by the PDCCH. Once the configured grant corresponding to the configured grant type <NUM> is activated, the terminal is allowed to skip the configured grant if the terminal has no data to be sent. There is no method for confirming the configured grant to enable the network side device to determine whether the terminal successfully receives the activation/deactivation command of the configured grant.

To sum up, the network side device cannot determine whether the terminal successfully receives the activation/deactivation command of the configured grant in the current activation/deactivation process of the configured grant.

A document (<NPL>) relates to a new mechanism, to support both dynamic Uu scheduling and dynamic SL scheduling at the same time, should be added to NR Uu, e.g., new RRC parameter is introduced to SR configuration, and the parameter represents either Ur or SL.

A document (<NPL>) relates to MAC architecture and MAC entity of the UE from a function point of view. The MAC subheader with LCID corresponding to MAC CE is used for identifying that MAC CE is a configured grant confirmation MAC CE. LCID: The Logical Channel ID field identifies the logical channel instance of the corresponding MAC SDU or the type of the corresponding MAC CE, or padding as described in Tables <NUM>. <NUM>-<NUM> and <NUM>. <NUM>-<NUM> for the DL-SCH and UL-SCH respectively. that is, the MAC subheader with LCID corresponding to MAC CE identifies the type of MAC CE.

The present application provides a configured grant confirmation method, a terminal and a network side device, so as to solve the problem that the network side device cannot determine whether the terminal successfully receives the activation/deactivation command of the configured grant in the current activation/deactivation process of the configured grant.

Obviously the described embodiments are merely a part of the embodiments of the present application but not all the embodiments. Based upon the embodiments of the present application, all of other embodiments obtained by those ordinary skilled in the art without creative work pertain to the protection scope of the present application.

Some embodiments of the present application will be further described in detail below in combination with the accompanying drawings of the specification.

As shown in <FIG>, a configured grant system provided by an embodiment of the present application includes a terminal <NUM> and a network side device <NUM>.

The terminal <NUM> is configured to receive a configured grant activation state management message sent by the network side device; and send a configured grant confirmation message to the network side device, so that the network side device determines the link type corresponding to the configured grant activation state management message successfully received by the terminal according to the received configured grant confirmation message.

The network side device <NUM> is configured to send the configured grant activation state management message to the terminal, receive the configured grant confirmation message sent by the terminal, and determine the link type corresponding to the configured grant activation state management message successfully received by the terminal according to the received configured grant confirmation message.

The configured grant activation state management message is used to activate or deactivate one or more sets of configured grants configured by the network side device for the terminal, and the configured grants are configured grants on a Uu link between a terminal and a cellular network and/or configured grants on a direct communication link between terminals.

Optionally, the configured grant activation state management message is a configured grant activation message or a configured grant deactivation message.

When the network side device sends a configured grant activation message to the terminal, it is used to activate one or more sets of configured grants configured by the network side device for the terminal; when the network side device sends a configured grant deactivation message to the terminal, it is used to deactivate one or more sets of configured grants configured by the network side device for the terminal.

Regarding the process in which the network side device sends the configured grant activation state management message to the terminal, an optional embodiment is:
the network side device sends the configured grant activation state management message to the terminal through PDCCH signaling or MAC (Media Access Control) CE (Control Element).

Correspondingly, the terminal receives the configured grant activation state management message sent by the network side device through PDCCH signaling or MAC CE.

The two ways to send the configured grant activation state management message will be respectively described below.

In a first way: the network side device sends the configured grant activation state management message to the terminal through PDCCH signaling.

When the network side device sends the configured grant activation state management message through PDCCH signaling, an RNTI scrambled by the PDCCH signaling indicates the link type corresponding to the configured grant activation state management message.

The terminal receives the configured grant activation state management message sent by the network side device through PDCCH signaling, and determines the link type corresponding to the configured grant activation state management message according to the RNTI scrambled by the PDCCH signaling.

Optionally, the PDCCH signaling further includes the frequency band resource indication information and/or a configured grant index.

Here, the frequency band resource indication information may be the BWP number.

When the network side device allocates resources to the terminal, a direct communication interface or Uu interface corresponds to at least one BWP, and one BWP corresponds to at least one set of configured grants; therefore, if the configured grant indexes on different BWPs are different, the network side device does not need to carry the BWP number when sending the configured grant activation state management message to the terminal; but if the configured grant indexes on different BWPs may overlap, the network side device needs to indicate the BWP corresponding to the configured grant that the terminal needs to activate or deactivate when sending the configured grant activation state management message to the terminal. Taking the latter as an example, in an implementation, the network side device carries the frequency band resource indication information in the PDCCH signaling, so as to indicate the number of the BWP corresponding to the configured grant that the terminal needs to activate or deactivate. The network side device carries the configured grant index in the PDCCH signaling, so as to indicate which set of configured grants the terminal needs to activate or deactivate.

In a second way: the network side device sends the configured grant activation state management message to the terminal through an MAC CE.

When the network side device sends the configured grant activation state management message to the terminal through the MAC CE, the link type corresponding to the configured grant activation state management message is indicated according to the following schemes.

Scheme <NUM>: the network side device sends a configured grant activation state management message that explicitly carries the link type indication information to the terminal.

Correspondingly, the terminal receives the configured grant activation state management message that explicitly carries the link type indication information sent by the network side device.

When the scheme <NUM> is used, the network side device displays and carries the link type indication information in the configured grant activation state management message, to indicate the link type that the terminal needs to activate or deactivate after receiving the configured grant activation state management message.

Optionally, the configured grant activation state management message further includes the frequency band resource indication information and/or a configured grant index.

When the network side device allocates resources to the terminal, a direct communication interface or Uu interface corresponds to at least one BWP, and one BWP corresponds to at least one set of configured grants; therefore, if the configured grant indexes on different BWPs are different, the network side device does not need to carry the BWP number when sending the configured grant activation state management message to the terminal; but if the configured grant indexes on different BWPs may overlap, the network side device needs to indicate the BWP corresponding to the configured grant that the terminal needs to activate or deactivate when sending the configured grant activation state management message to the terminal. Taking the latter as an example, in an implementation, the network side device carries the frequency band resource indication information in the configured grant activation state management message, so as to indicate the number of the BWP corresponding to the configured grant that the terminal needs to activate or deactivate. The network side device carries the configured grant index in the configured grant activation state management message, so as to indicate which set of configured grants the terminal needs to activate or deactivate.

When the network side device sends the configured grant activation state management message that explicitly carries the link type indication information to the terminal, an optional embodiment is: the link type indication information is carried by the MAC subheader corresponding to the MAC CE or by the MAC CE itself.

If the link type indication information is carried by the MAC subheader corresponding to the MAC CE, the link type indication information is carried by an LCID contained in the MAC subheader corresponding to the MAC CE, or the link type indication information is carried by a reserved field R contained in the MAC subheader corresponding to the MAC CE.

When the configured grant activation state management message includes the link type indication information and the configured resource number, the format of the MAC subheader is shown in <FIG>. If the link type indication information is carried by the reserved field R contained in the existing MAC subheader, one R bit can be set as the Link indication field, wherein the values <NUM> and <NUM> of the Link field respectively represent two different communication links, for example, the value of <NUM> represents a Uu link, and the value of <NUM> represents a direct communication link; if the link type indication information is carried by the LCID contained in the existing MAC header, different LCIDs can be used to distinguish different link types, for example, the LCID value of <NUM> represents a direct communication link, and the LCID value of <NUM> represents a Uu interface link; the format of the MAC CE is shown in <FIG>, wherein the communication interface is configured with <NUM> sets of configured grants as an example; CGi represents the configured grant indexed i.

When the configured grant activation state management message includes the link type indication information, the configured resource number and the frequency band resource indication information, the format of the MAC subheader is shown in <FIG>. If the link type indication information is carried by the reserved field R contained in the existing MAC subheader, one R bit can be set as the Link indication field, wherein the values <NUM> and <NUM> of the Link field respectively represent two different communication links, for example, the value of <NUM> represents a Uu link, and the value of <NUM> represents a direct communication link; if the link type indication information is carried by the LCID contained in the existing MAC header, different LCIDs can be used to distinguish different link types, for example, the LCID value of <NUM> represents a direct communication link, and the LCID value of <NUM> represents a Uu interface link. The format of the MAC CE is shown in <FIG>, wherein the communication interface corresponds to up to <NUM> BWPs and each BWP supports up to <NUM> sets of configured grants as an example. BWPj indicates whether the MAC CE contains the activation/deactivation confirmation message of the configured grant corresponding to the BWP numbered j, and CGji represents the configured grant indexed i on the BWPj, wherein i and j are both integers greater than or equal to <NUM>.

Scheme <NUM>: the network side device sends a configured grant activation state management message containing a configured grant index to the terminal.

Correspondingly, the terminal receives the configured grant activation state management message containing the configured grant index sent by the network side device.

The configured grant index is used to implicitly indicate the link type corresponding to the configured grant activation state management message.

When the scheme <NUM> is used, there is a preset correspondence between the configured grant index and the link type; for example, when the configured grant index ranges from <NUM> to <NUM>, the link type corresponding to the configured grant index is Uu link; when the configured grant index ranges from <NUM> to <NUM>, the link type corresponding to the configured grant index is direct communication link.

Optionally, the configured grant activation state management message also includes the frequency band resource indication information.

When the network side device allocates resources to the terminal, a direct communication interface or Uu interface corresponds to at least one BWP, and one BWP corresponds to at least one set of configured grants; therefore, if the configured grant indexes on different BWPs are different, the network side device does not need to carry the BWP number when sending the configured grant activation state management message to the terminal; but if the configured grant indexes on different BWPs may overlap, the network side device needs to indicate the BWP corresponding to the configured grant that the terminal needs to activate or deactivate when sending the configured grant activation state management message to the terminal. Taking the latter as an example, in an implementation, the network side device carries the frequency band resource indication information in the configured grant activation state management message, so as to indicate the number of the BWP corresponding to the configured grant that the terminal needs to activate or deactivate.

It should be noted that, in some embodiments of the present application, one link type corresponds to at least one configured grant index, and different link types correspond to different configured grant indexes.

Here, the configured grant indexes corresponding to the link types are configured by the network side device or agreed by protocol.

In an implementation, when the network side device configures the configured grants, the ranges of configured grant indexes corresponding to different communication links are configured to be different; for example, when the network side device configures the configured grants, the corresponding configured grant index is configured for the Uu communication link in the first range from <NUM> to <NUM>, and the corresponding configured grant index is configured for the direct communication link in the second range from <NUM> to <NUM>.

Alternatively, the protocol stipulates that the ranges of configured grant indexes corresponding to different communication links are different. For example, the protocol stipulates that the range of the configured grant index corresponding to the Uu communication link is <NUM> to <NUM>, and the range of the configured grant index corresponding to the direct communication link is <NUM> to <NUM>.

Scheme <NUM>: the network side device determines a physical resource location corresponding to the configured grant activation state management message, and sends the configured grant activation state management message at the determined physical resource location.

The physical resource location corresponding to the configured grant activation state management message is used to implicitly indicate the link type corresponding to the configured grant activation state management message.

When the scheme <NUM> is used, there is a preset correspondence between the physical resource location used by the network side device to send the configured grant activation state management message and the link type; the network side device selects the physical resource location corresponding to the link type according to the link type that needs to be activated or deactivated before sending the configured grant activation state management message to the terminal, and sends the configured grant activation state management message at the selected physical resource location. Correspondingly, after receiving the configured grant activation state management message, the terminal determines the link type corresponding to the configured grant activation state management message according to the physical resource location used to send the configured grant activation state management message.

In an embodiment of the present application, after receiving the configured grant activation state management message, the terminal sends a configured grant confirmation message to the network side device, so that the network side device determines that the terminal has successfully received the configured grant activation state management message, and determines the link type corresponding to the configured grant activation state management message successfully received by the terminal according to the configured grant confirmation message.

The process in which the terminal sends the configured grant confirmation message to the network side device will be illustrated below in details.

The terminal sends the configured grant confirmation message to the network side device through an MAC CE or RRC signaling.

Correspondingly, the network side device receives the configured grant confirmation message sent by the terminal through an MAC CE or RRC signaling.

In an embodiment of the present application, when the terminal sends the configured grant confirmation message to the network side device, the link type corresponding to the configured grant confirmation message may be indicated by using the following schemes.

Scheme <NUM>: the terminal sends a configured grant confirmation message that explicitly carries the link type indication information to the network side device.

Correspondingly, the network side device receives the configured grant confirmation message that explicitly carries the link type indication information sent by the terminal, and determines the link type corresponding to the configured grant activation state management message successfully received by the terminal according to the link type indication information.

Optionally, the configured grant confirmation message includes the frequency band resource indication information and/or a configured grant index.

When the network side device allocates resources to the terminal, a direct communication interface or Uu interface corresponds to at least one BWP, and one BWP corresponds to at least one set of configured grants; therefore, if the configured grant indexes on different BWPs are different, the network side device does not need to carry the BWP number when sending the configured grant activation state management message to the terminal; but if the configured grant indexes on different BWPs may overlap, the terminal needs to indicate to the network side device the BWP corresponding to the configured grant that is activated or deactivated by the configured grant activation state management message successfully received by the terminal when sending the configured grant confirmation message to the network side device. Taking the latter as an example, in an implementation, the terminal carries the frequency band resource indication information in the configured grant confirmation message, so as to indicate to the network side device the number of the BWP corresponding to the configured grant activation state management message received by the terminal. The terminal carries the configured grant index in the configured grant confirmation message, so as to indicate to the network side device which set of configured grants corresponds to the configured grant activation state management message successfully received by the terminal.

When the terminal sends a configured grant confirmation message to the network side device through an MAC CE and the configured grant confirmation message needs to explicitly carry the link type indication information, an optional embodiment is: the link type indication information is carried by the MAC subheader corresponding to the MAC CE or by the MAC CE itself.

When the configured grant confirmation message includes the link type indication information and the configured resource number, the format of the MAC subheader is shown in <FIG>. If the link type indication information is carried by the reserved field R contained in the existing MAC subheader, one R bit can be set as the Link indication field, wherein the values <NUM> and <NUM> of the Link field respectively represent two different communication links, for example, the value of <NUM> represents a Uu link, and the value of <NUM> represents a direct communication link; if the link type indication information is carried by the LCID contained in the existing MAC header, different LCIDs can be used to distinguish different link types, for example, the LCID value of <NUM> represents a direct communication link, and the LCID value of <NUM> represents a Uu interface link; the format of the MAC CE is shown in <FIG>, wherein the communication interface is configured with <NUM> sets of configured grants as an example; CGi represents the configured grant indexed i.

When the configured grant confirmation message includes the link type indication information, the configured resource number and the frequency band resource indication information, the format of the MAC subheader is shown in <FIG>. If the link type indication information is carried by the reserved field R contained in the existing MAC subheader, one R bit can be set as the Link indication field, wherein the values <NUM> and <NUM> of the Link field respectively represent two different communication links, for example, the value of <NUM> represents a Uu link, and the value of <NUM> represents a direct communication link; if the link type indication information is carried by the LCID contained in the existing MAC header, different LCIDs can be used to distinguish different link types, for example, the LCID value of <NUM> represents a direct communication link, and the LCID value of <NUM> represents a Uu interface link. The format of the MAC CE is shown in <FIG>, wherein the communication interface corresponds to up to <NUM> BWPs and each BWP supports up to <NUM> sets of configured grants as an example. BWPj indicates whether the MAC CE contains the activation/deactivation confirmation message of the configured grant corresponding to the BWP numbered j, and CGji represents the configured grant indexed i on the BWPj.

Scheme <NUM>: the terminal sends a configured grant confirmation message containing a configured grant index to the network side device; wherein the configured grant index is used to implicitly indicate the link type corresponding to the configured grant confirmation message.

Correspondingly, the network side device receives the configured grant confirmation message containing the configured grant index sent by the terminal; and determines the link type corresponding to the configured grant activation state management message successfully received by the terminal according to the configured grant index.

Optionally, the configured grant confirmation message also includes the frequency band resource indication information.

When the network side device allocates resources to the terminal, a direct communication interface or Uu interface corresponds to at least one BWP, and one BWP corresponds to at least one set of configured grants; therefore, if the configured grant indexes on different BWPs are different, the network side device does not need to carry the BWP number when sending the configured grant activation state management message to the terminal; but if the configured grant indexes on different BWPs may overlap, the terminal needs to indicate to the network side device the BWP corresponding to the configured grant that is activated or deactivated by the configured grant activation state management message successfully received by the terminal when sending the configured grant confirmation message to the network side device. Taking the latter as an example, the terminal carries the frequency band resource indication information in the configured grant confirmation message, so as to indicate to the network side device the number of the BWP corresponding to the configured grant activation state management message received by the terminal.

Scheme <NUM>: the terminal determines a physical resource location corresponding to the configured grant confirmation message, and sends the configured grant confirmation message at the determined physical resource location.

Here, the physical resource location corresponding to the configured grant confirmation message is used to implicitly indicate the link type corresponding to the configured grant confirmation message.

When the scheme <NUM> is used, there is a preset correspondence between the physical resource location used by the terminal to send the configured grant confirmation message and the link type; the terminal selects the physical resource location corresponding to the link type according to the link type corresponding to the configured grant activation state management message successfully received before sending the configured grant confirmation message to the network side device, and sends the configured grant confirmation message at the selected physical resource location. Correspondingly, after receiving the configured grant confirmation message, the network side device determines the link type corresponding to the configured grant activation state management message successfully received by the terminal according to the physical resource location used to send the configured grant confirmation message.

For example, if the direct communication link interface only supports a set of configured grants, it is possible to define that the link type corresponding to the configured grant confirmation message is determined as direct communication link if the configured grant confirmation message is transmitted through the non-configured grant resources of the Uu interface; or
if the direct communication link interface supports multiple sets of configured grants, a group of PUSCH (Physical Uplink Shared Channel) resources (the number of PUSCH resources depends on the number of sets of configured grants supported by the direct communication link interface) is defined, and this group of PUSCH resources are used to transmit the configured grant confirmation message of the direct communication link.
