As shown in fig. 2A, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S1110: monitoring DCI, wherein one DCI comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of the configured transmission on the plurality of carriers.

The transmission processing method may be performed by a terminal. The terminal may be various types of terminals including, but not limited to: cell phones, tablet computers, wearable devices, vehicle-mounted devices, smart home devices and/or smart office devices.

Illustratively, the terminal supports multiple connections, e.g., dual connections.

The terminal listens for DCI on a physical downlink control channel (Physical Downlink Control Channel, PDCCH). But one DCI monitored in an embodiment of the present disclosure may indicate activation information for a configured transmission on multiple carriers. In the embodiments of the present disclosure, a plurality refers to two or more.

Wherein indicating activation and/or deactivation of a configured transmission on the plurality of carriers refers to one or more of:

activating a configured transmission on each of a plurality of carriers;

deactivating configured transmissions on each of the plurality of carriers;

activating configured transmissions on at least two of the plurality of carriers; and

The configured transmissions on at least two of the plurality of carriers are deactivated.

In the disclosed embodiments, the configuration transmission may be one or more of the following: PDSCH, PDCCH, PUSCH, and PUCCH.

The transmission configured on the plurality of carriers herein may include: downlink and/or uplink transmissions configured on multiple carriers. The uplink transmission and/or the downlink transmission herein may be used for transmission of various services. Illustratively, the uplink transmission may be used for an augmented reality (eXtended Reality, XR) traffic transmission.

XR services may involve audio data, video data and/or text data, which may be transmitted via different service carriers of the terminal, and which have an association.

Specifically, XR services may include enhanced display (Augment Reality, AR), virtual Reality (VR), cloud Gaming (Cloud Gaming), and/or the like. The XR service features are: the frame rate of the traffic is fixed, i.e. the traffic arrives at the terminal for a fixed period, but there is an additional delay Jitter (Jitter) above this fixed period, resulting in the actual data traffic arriving at the terminal being either advanced or delayed. XR traffic conditions may be as shown in fig. 3, with transmission between data packet K and data packet k+1 at a fixed frame rate, but with possible delay jitter between data packet K and data packet k+1.

One possible example is a Frame rate of 60 Frames Per Second (FPS), i.e. a period of 16.67ms. The delay jitter range is [4, -4] ms). The number of bits included in a frame is large and the frame is divided into a plurality of transport blocks (Transmission Block, TB). The multiple TBs are transmitted on different physical resource blocks. The plurality of physical resource blocks may be configured on the same or different time units of different service carriers of the terminal. The time units include, but are not limited to: time slots and/or symbols.

In one embodiment, the configured transmissions on the plurality of carriers may understand the scheduling of one or more channels on the plurality of carriers. The transmission configured on the multiple carriers is understood herein to be the scheduling of the same service or different services on the multiple carriers.

In some embodiments, the plurality of carriers may include carriers of different serving cells.

In other embodiments, the plurality of carriers may be supplemental carriers and non-supplemental carriers. The non-supplementary carrier herein is any carrier other than the supplementary carrier. Illustratively, the supplemental carrier includes, but is not limited to, a supplemental uplink (Supplementary uplink, SUL) carrier.

The plurality of carriers indicated by the activation information included in one DCI may be from one carrier group or from a different carrier group. Illustratively, the carrier group may include: a primary cell Group (MASTER CELL Group, MCG) carrier, and/or a secondary cell (Secondary Cell Group, SCG) carrier Group.

One or more of the transmissions configured on one carrier may be, for example, uplink and/or downlink transmissions may be configured for different channels, where one DCI includes: the activation information of the same transmission configured on a plurality of carriers of the terminal or the activation information of different transmissions configured on a plurality of carriers of the terminal.

Assuming that two types of transmission, namely shared channel transmission and/or control channel transmission, are configured on a service carrier A and a service carrier B of the terminal, the activation information contained in the DCI indicates activation or deactivation of the same type of transmission, and the activation information individually indicates activation or deactivation of the shared channel transmission on the service carriers A and B of the terminal; or the activation information indicates activation or deactivation of control channel transmissions on the terminal's service carriers a and B, respectively. Of course, assuming that the activation information in one DCI indicates activation or deactivation of multiple transmission configurations on multiple carriers (i.e., configured transmissions on multiple carriers), the activation information contained in one DCI may simultaneously indicate activation and/or deactivation of multiple channel transmissions configured by serving carrier a.

Notably, are: the activation information contained in one DCI may activate multiple carriers simultaneously or deactivate multiple carriers simultaneously; or activate and deactivate a portion of the plurality of carriers.

Of course, the above is merely an example of a plurality of carriers, and the specific implementation is not limited to the above example.

Since the terminal can know the activation information of the configured transmission on the plurality of service carriers of the terminal only by monitoring one DCI, it is not necessary to monitor the DCI of the configured transmission on each carrier separately. Because the monitoring of DCI is blind detection, the number of DCI for blind detection of the terminal is reduced, the power consumption of DCI for blind detection of the terminal is reduced, and the efficiency is improved.

The activation information may be used to indicate activation or deactivation of a configured transmission on the plurality of carriers.

Illustratively, when the activation information indicates activation, an activation instruction carried by the DCI; when the activation information indicates deactivation signaling.

In some embodiments, the DCI includes a preset information field;

And the preset information field is used for activating and/or deactivating the transmission configured on the plurality of carriers by indicating the plurality of carriers corresponding to the transmission.

Illustratively, the DCI may include one or more information fields. In the embodiment of the present disclosure, the DCI has an information field indicating a carrier, where the information field is the preset information field.

In one embodiment, the preset information field may include a bit map (bitmap), and one bit in the bit map may correspond to one service carrier of the terminal. Thus, the values of "0" and "1" of this bit may be used to indicate that both states are activated or deactivated. Assuming that the terminal has S service carriers, the DCI includes a bit map having S bits. Thus, after receiving one DCI, the terminal knows the states in which S service carriers are activated or deactivated.

In another embodiment, the preset information field may have one or more bits, and in any case, a bit value combination carried by one or more bits in the preset information field may refer to a state of activation and/or deactivation of S service carriers of a terminal. For example, the preset information field has 2 bits, may have 4 bit value combinations indicating the active and/or inactive state combinations of the 4S service carriers. In summary, the preset information field specifically indicates activation or deactivation of a transmission configured by a plurality of service carriers of the terminal.

As shown in fig. 2B, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S1210: determining a first carrier for monitoring the DCI;

S1220: listening for DCI on a first carrier, wherein one of the DCIs comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of the configured transmission on the plurality of carriers.

In the embodiment of the disclosure, the terminal may determine to monitor the first carrier of the DCI first, so that the terminal may monitor the DCI on one carrier without blindly detecting all the service carriers of the terminal itself.

Specifically, the S1210 may include: and defaulting the carrier in the primary cell to the first carrier or the carrier of the primary and secondary cells to the first carrier.

There are many ways to determine the first carrier, and in any case the first carrier may be any one carrier of a plurality of service carriers of the terminal.

In one embodiment, one DCI heard on the first carrier may include activation information of a plurality of service carriers, respectively, or common activation information of a plurality of service carriers. The common activation information collectively indicates activation or deactivation of the respective carriers, and the like.

As shown in fig. 2C, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

s1310: determining a first carrier wave for monitoring the DCI according to the received high-layer signaling;

S1320: listening for DCI on a first carrier, wherein one of the DCIs comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of the configured transmission on the plurality of carriers.

In the embodiment of the disclosure, the terminal receives higher layer signaling sent by the base station, where the higher layer signaling includes, but is not limited to: RRC signaling and/or MAC layer signaling including, but not limited to, MAC Control Element (CE).

Illustratively, the higher layer signaling may include a carrier identifier, where the carrier indicated by the carrier identifier is the first carrier.

The terminal determines a first carrier for monitoring DCI according to a high-layer signaling issued by network equipment such as a base station and the like, and monitors DCI containing activation information of a plurality of service carriers on the first carrier.

For example, the higher layer signaling may be issued prior to DCI, so that the terminal may determine the first carrier listening to DCI according to the received higher layer signaling before listening to DCI.

As shown in fig. 2D, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S1410: determining a first carrier for monitoring the DCI according to protocol conventions;

S1420: listening for DCI on a first carrier, wherein one of the DCIs comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of the configured transmission on the plurality of carriers.

In the embodiment of the disclosure, the terminal may determine to monitor the first carrier of the activation information DCI simultaneously containing multiple carriers according to a protocol convention.

After determining the first carrier, the DCI may be monitored on the first carrier.

As shown in fig. 2E, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S1510: monitoring DCI, wherein one DCI comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of the configured transmission on the plurality of carriers;

s1520: the plurality of carriers associated with the activation information are determined.

In the embodiment of the disclosure, the terminal may determine a plurality of carriers associated with carrier information included in the DCI. The plurality of carriers may be all or part of the plurality of serving carriers of the terminal.

There may be a variety of ways to determine the multiple carriers associated with the current activation information, for example, the activation information may default to the carrier of the MCG or the carrier of the SCG or all the service carriers of the associated terminal.

Notably, are: s1520 may be performed prior to S1510, S1510 may be performed prior to S1520, or S1510 and S1520 may be performed simultaneously.

In other embodiments, the S1520 may include:

and determining the multiple carriers associated with the activation information according to the high-layer signaling.

The higher layer signaling includes, but is not limited to: RRC signaling and/or MAC layer signaling including, but not limited to, MAC Control Element (CE). The higher layer signaling may include indication information of the plurality of carriers associated with the activation information. The indication information may comprise a carrier identity and/or an indication bit associated with a serving carrier of the terminal, etc.

In some embodiments, the higher layer signaling used to determine the plurality of carriers associated with the activation information may be the same higher layer signaling as the higher layer signaling used to determine the first carrier, or may be different higher layer signaling.

If the higher layer signaling used for determining the multiple carriers associated with the activation information and the higher layer signaling used for determining the first carrier are the same higher layer signaling, the terminal can know to monitor the first carrier containing the DCI configured for transmission on the multiple carriers and the multiple carriers associated with the activation information through one higher layer signaling.

If two different high-level signaling are used to respectively receive the high-level signaling for determining the multiple carriers associated with the activation information and the high-level signaling for determining the first carrier, the base station side can flexibly configure the high-level signaling according to the requirement.

In some embodiments, the S1520 may include: and determining the multiple carriers associated with the activation information according to the protocol convention.

In the embodiment of the disclosure, the multiple carriers associated with the activation information are determined according to a protocol convention. If the protocol has a contract, the method is directly executed according to the protocol, so that signaling interaction between the base station and the terminal is not needed, and signaling overhead is reduced.

In some embodiments, if the protocol has a contract and receives a higher layer signaling that is monitored by a network device such as a base station, the first carrier monitoring the DCI and/or the multiple carriers associated with the activation information are determined according to the higher layer signaling. I.e. the priority of higher-layer signaling issued by network side equipment such as a base station can be higher than the protocol convention. If the terminal does not receive the higher layer signaling, the first carrier for monitoring the DCI and/or a plurality of carriers associated with the activation information can be determined according to protocol convention.

In one embodiment, the activation information included in the DCI transmitted on the first carrier may be common activation information. The activation information may be an activation instruction or a deactivation instruction. If the activation information is an activation instruction, indicating that a plurality of carriers associated with the activation information are all activated; if the activation information is a deactivation instruction, the activation information indicates that the multiple carriers associated with the activation information are deactivated. In this way, the activation information contained in the DCI transmitted by the first carrier does not indicate the activation or deactivation states of the respective carriers by using different bits, but indicates the activation or deactivation states uniformly, so that the bit overhead of the DCI is further reduced.

That is, the activation information indicates activation, and transmissions configured on the plurality of carriers are all activated; or the activation information indicates deactivation, and transmissions configured on the plurality of carriers are all deactivated.

In some embodiments, the plurality of carriers associated with the activation information are from one or more carrier groups;

one of the carrier groups includes one or more of the carriers.

The multiple carriers associated with the activation information may be from one or more carrier groups, for example, the multiple carriers associated with the activation information are from the same carrier group, and then the higher-layer signaling indicating the multiple carriers associated with the activation information may be indicated by carrying the group identifier of the carrier group.

If the multiple carriers associated with the activation information come from different carrier groups, the higher-layer signaling indicating that the multiple carriers associated with the activation information can be implemented by carrying carrier identifiers of each carrier in the multiple carriers.

As shown in fig. 2F, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S1610: monitoring DCI;

S1620: if the transmission carrier of the DCI is monitored to be the second carrier agreed by the protocol, determining that the activation information carried by the DCI is used for indicating activation or deactivation of transmission configured on a plurality of carriers of the terminal.

In some embodiments, the terminal supports listening of multiple DCIs carrying activation information. For example, the terminal supports listening for DCI carrying activation information for configured transmissions on a single carrier, while also supporting DCI carrying activation information for configured transmissions on multiple carriers.

And if the terminal monitors the DCI on the second carrier, the DCI is used for indicating the activation or deactivation of the transmission configuration of the plurality of carriers supported by the terminal.

If the terminal listens to DCI on a carrier other than the second carrier (e.g., the third carrier), the DCI indicates activation or deactivation of a transmission configured on the corresponding third carrier.

In some embodiments, the transmission carrier of the DCI is a second carrier agreed by a protocol, and the activation information carried by the DCI is used to indicate activation or deactivation of transmissions configured on all service carriers of the terminal.

The protocol agrees that if the second carrier monitors the DCI carrying the activation information, the activation information carried by the DCI is applicable to all service carriers of the terminal.

The activation information may be indicated by one or more bits. Assuming that the activation information has only 1 bit, the two bit values "0" and "1" of the bit may be used to indicate the activation or deactivation of two states of a configured transmission on all service carriers of the terminal

In some embodiments, the transmitting comprises:

Semi-persistent physical downlink shared channel (Semi-PERSISTENT SCHEDULING-Physical Downlink SHARED CHANNEL, SPS-PDSCH) transmissions;

Or alternatively

An authorized Physical Uplink shared channel (Configured Grant-Physical Uplink SHARED CHANNEL, CG-PUSCH) transmission is Configured.

Illustratively, the CG-PUSCH transmission (CG-PUSCH schedule) may be a CG-PUSCH of type (type) 2.

In some embodiments, the CG-PUSCH may also include a CG-PUSCH of type 1. CG-PUSCH for type 1 may be used directly without activation once configuration is complete.

Those skilled in the art will appreciate that the various embodiments illustrated in fig. 2A-2F may be performed by the terminal device either independently or in any combination, and the embodiments of the present disclosure are not limited in this respect.

As shown in fig. 4A, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S2110: transmitting Downlink Control Information (DCI), wherein one DCI comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of transmission on the plurality of carriers.

The method may be performed by a network device such as a base station. The base stations include, but are not limited to, evolved base stations (enbs) or next generation base stations (gnbs).

For example, the transmission may be any transmission requiring DCI activation or deactivation, and specifically, may include uplink transmission and/or downlink transmission requiring DCI activation or deactivation, according to uplink and downlink distinction.

One DCI transmitted by the base station may carry activation information of a transmission configured by multiple carriers, that is, activation information for implementing a single DCI cross-carrier indication of the configured transmission.

The base station can send DCI containing the activation information of the transmission configured by the plurality of carriers on the PDCCH, so that the base station can send one DCI on one carrier to realize the sending of the activation information on the plurality of carriers, and compared with the method of sending the DCI containing the activation information of the transmission configured by the corresponding carrier on the plurality of carriers, the signaling overhead can be reduced.

In some embodiments, the DCI includes a preset information field;

In one embodiment, the preset information field may include a bit map, and a bit in the bit map may correspond to a service carrier of the terminal. Thus, the values of "0" and "1" of this bit may be used to indicate that both states are activated or deactivated. Assuming that the terminal has S service carriers, the DCI includes a bit map having S bits. Thus, after receiving one DCI, the terminal knows the states in which S service carriers are activated or deactivated.

In another embodiment, the preset information field may have one or more bits, and in any case, a bit value combination carried by one or more bits in the preset information field may refer to a state of activation and/or deactivation of S service carriers of a terminal. For example, the preset information field has 2 bits, may have 4 bit value combinations indicating the active and/or inactive state combinations of the 4S service carriers.

In summary, the preset information field specifically indicates activation or deactivation of a transmission configured by a plurality of service carriers of the terminal.

As shown in fig. 4B, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

S2210: determining a first carrier for transmitting the DCI;

s2220: transmitting Downlink Control Information (DCI), wherein one DCI comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of transmission on the plurality of carriers.

In the embodiment of the present disclosure, before transmitting DCI, the base station determines a first carrier for transmitting DCI to the terminal.

Illustratively, the determining the first carrier that transmitted the DCI includes:

determining a first carrier wave for transmitting the DCI according to the transmitted high-layer signaling;

Or alternatively

And determining a first carrier for transmitting the DCI according to protocol conventions.

In one embodiment, if there is no protocol for transmitting the first carrier of the DCI, the base station indicates the first carrier to the terminal by sending out higher layer signaling, or if the protocol has a carrier for transmitting the DCI, but the base station considers that the carrier signal used by the protocol is poor in quality or is too high in load rate, and at this time, the base station may still indicate the first carrier to the terminal through the transmission of the higher layer signaling.

If the base station sends a high-layer signaling for determining the first carrier, the base station determines the first carrier for sending DCI according to the high-layer signaling; if the base station does not transmit the first carrier which can determine to transmit the DCI according to the protocol convention, or if the protocol convention does not exist, the first carrier which can transmit the DCI can be determined according to the pre-negotiation or default rule between the terminal and the base station.

As shown in fig. 4C, an embodiment of the present disclosure provides a transmission processing method, where the method includes:

s2310: a plurality of carriers associated with the activation information is determined.

S2320: transmitting Downlink Control Information (DCI), wherein one DCI comprises: activation information for configured transmissions on a plurality of carriers; wherein the activation information is used for indicating activation and/or deactivation of transmission on the plurality of carriers.

In the embodiment of the present disclosure, the base station determines a plurality of carriers associated with the activation information, and configures the activation information carried by the DCI according to the requirement of whether the transmission configured on the plurality of carriers needs activation.

For example, the base station may determine multiple carriers associated with the activation information carried in one DCI according to a protocol engagement point, or may determine multiple carriers managed by the activation information carried in one DCI according to a pre-negotiation between the base station and the terminal.

In some embodiments, the S2310 may include:

Determining the multiple carriers associated with the activation information according to the high-layer signaling;

and/or

And determining the multiple carriers associated with the activation information according to the protocol convention.

If the base station determines activation information in one DCI associated with a plurality of service carriers of a single terminal, the activation information can be indicated to the terminal through high-layer signaling. At this time, the base station may send the higher layer signaling first, and if the base station sends the higher layer signaling first, the base station may send multiple carriers associated with the activation information according to the higher layer signaling sent by itself.

In other embodiments, the base station may not send higher layer signaling, and may determine the multiple carriers associated with the activation information directly based on the protocol convention.

In some embodiments, the transmissions configured on the plurality of carriers are all active, the activation information indicating activation; or all transmissions configured on the plurality of carriers are deactivated, the activation information indicating deactivation.

To reduce bit overhead, activation information within one DCI may indicate activation or deactivation, in which case multiple carriers associated with the activation information will be activated or deactivated simultaneously.

In one embodiment, the plurality of carriers associated with the activation information are from one or more carrier groups;

one of the carrier groups includes one or more of the carriers.

For example, the plurality of carriers associated with the activation information contained in one DCI may be from the same carrier group or different carrier groups. For example, it may be achieved that a plurality of carriers within one carrier group are simultaneously deactivated or activated by one DCI.

For example, in some embodiments, the multiple carriers associated with the activation information may be from different carrier groups, such that activation and/or deactivation of multiple carriers across carrier groups may be achieved.

In some embodiments, the transmission carrier of the DCI is a second carrier agreed by a protocol, and the activation information carried by the DCI is used to indicate activation or deactivation of a transmission configured on multiple carriers of the terminal.

In one embodiment, a specific second carrier may be predetermined, and if the base station wants to activate or deactivate multiple carriers of the terminal, the DCI may be transmitted through the second carrier. The second carrier may be, but is not limited to, a carrier of a primary cell or a carrier of a primary and secondary cell of the terminal.

In this embodiment, if the base station needs to activate or deactivate a single carrier of the terminal, DCI including activation information may be sent on a service carrier of the terminal other than the second carrier. In some embodiments, the transmission carrier of the DCI is a second carrier agreed by a protocol, and the activation information carried by the DCI is used to indicate activation or deactivation of transmissions configured on all service carriers of the terminal.

The activation information contained in the DCI carried by the second carrier may be used to indicate activation or deactivation of a transmission configured by a portion of the serving carrier of the terminal. In the implementation of the present disclosure, the activation information carried by the DCI sent by the second carrier may be used to indicate activation or deactivation of the transmission configured by all the carriers of the terminal.

The second carrier is agreed in the embodiments of the present disclosure, and in other embodiments, the second carrier may be determined in other manners, for example, determined by negotiation between the base station and the terminal, or designated by the base station to the terminal through higher layer signaling. The higher layer signaling may also include: RRC signaling and/or MAC CE signaling, etc.

semi-persistent physical downlink shared channel SPS-PDSCH transmissions;

Or alternatively

The embodiment of the disclosure provides an energy-saving method for activating and deactivating semi-persistent downlink transmission, which can be applied to a scenario in which SPS PDSCH transmission is configured on a plurality of carriers.

A single DCI can activate or deactivate a configured SPS PDSCH on multiple carriers.

The base station transmits to the terminal one DCI which can activate/deactivate SPS PDSCH transmission (or called scheduling) on multiple carriers.

An information field in the activation/deactivation DCI is used, the information field pointing to multiple carriers. Activation or deactivation of SPS PDSCH transmissions for these multiple carriers is handled by information carried by the information domain.

The information field may be the aforementioned predetermined information field.

In some embodiments, the first carrier is configured by higher layer signaling as a carrier of DCI transmitting SPS PDSCH activation information, and the terminal only needs to blindly detect the DCI activated/deactivated by SPS PDSCH on the first carrier. The first carrier may be one or more.

In some embodiments, higher layer signaling may be used to configure the relationship of the first carrier to its corresponding set of active/inactive carriers. That is, if the terminal receives the activation/deactivation DCI on the first carrier, the activation/deactivation command is valid on a plurality of carriers included in the activation/deactivation carrier group. The active carrier group and the inactive carrier group may be the same or may be configured separately.

In some embodiments, the protocol specifies an activation/deactivation instruction sent on a carrier (i.e., on one serving cell) that is applicable to activation/deactivation of SPS PDSCH on all serving carriers (i.e., serving cells) of the terminal. The carrier used by the serving cell may be the aforementioned second carrier.
