Description

Transmission processing method, device, electronic equipment and storage medium

Technical Field

Embodiments of the present invention relate to the field of communications technologies, and in particular, to a method and an apparatus for transmission processing, an electronic device, and a storage medium.

Background

In an LTE (Long Term Evolution ) system, a base station realizes uplink and downlink transmission configuration through DCI (Downlink Control Information ), where one of the configurations is a TTI (Transmission Time Interval ) parameter.

The TTI may represent a base station scheduling interval and a feedback interval, the scheduling interval may include a downlink control channel and its scheduled downlink traffic channel interval, a downlink control channel and its scheduled uplink traffic channel interval, and the feedback interval may include a downlink traffic channel and its corresponding uplink feedback control channel interval, and an uplink traffic channel and its corresponding downlink feedback control channel interval. Typically, the TTI is a fixed number.

For FDD (Frequency Division Duplexing, frequency division duplex) mode of operation, the downlink control channel and its scheduled downlink traffic channel interval is 0, and the downlink traffic channel and its scheduled uplink traffic channel interval and its corresponding uplink feedback control channel interval are 4 TTI interval lengths, i.e. the number of TTIs of the scheduled and feedback intervals is fixed.

For TDD (Time Division Duplexing, time division duplex) mode of operation, the scheduling and feedback intervals may include, accordingly, downlink control channel to its scheduled downlink traffic channel interval, downlink control channel to its scheduled uplink traffic channel interval, and downlink traffic channel to its corresponding uplink feedback control channel interval, uplink traffic channel to its corresponding downlink feedback control channel interval. Wherein for each TDD configuration (0-6), there is also a fixed number of interval TTIs for scheduling or feedback to occur in different subframes (0-9).

In 5G (5 rd-Generation, fifth Generation mobile communication technology) NR (New Radio Access Technology in 3GPP, radio access technology) technology, services with different requirements, such as EMBB (Enhance Mobile Broadband, ultra large data volume broadband service), URLLC (Ultra-reliable and low latency communications, low latency high reliability service) and the like, need to be supported.

For example, for an EMBB service, a larger TTI is adopted to support a larger number of HARQ processes to satisfy the transmission of a large amount of data; for the URLLC service, a smaller scheduling interval is adopted, and a smaller number of HARQ processes are supported so as to meet the requirement of the URLLC service on lower time delay.

In the development of the prior art and standard discussion, the TTI is mainly configured by DCI in a downlink control channel, and the PDCCH is used for carrying DCI of one or more UEs (User Equipment), that is, the DCI is the UE-specific DCI because the DCI is scrambled by using a UE identifier C-RNTI that can uniquely identify the UE, or the DCI is configured in a UE-specific search space.

It can be understood that if the base station uses the UE identifier C-RNTI to scramble in each TTI transmission, so that the UE descrambles the DCI according to the pre-acquired C-RNTI, or uses the DCI of the UE-specific search space to indicate the TTI, so that the UE acquires the TTI in the UE-specific search space, which occupies a large amount of time domain resources.

At present, no corresponding method is available to solve the problem of resource waste in the prior art.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments.

The embodiment of the invention can be applied to various networks, and for the sake of clarity of explanation, the embodiment of the invention will be described by taking 5G as an example.

In the 5G network, a technical means of carrying Group common downlink control information (Group-common DCI) on a Group common downlink physical channel (Group-common PDCCH) is proposed. The group public downlink physical channel is a channel which can be monitored by a group of UE, and the group public downlink control information is DCI which can be acquired by a group of UE.

Fig. 1 is a schematic flow chart of a method for transmission processing according to an embodiment of the present invention.

As shown in fig. 1, the method provided by the embodiment of the invention specifically includes the following steps:

11. transmitting a group public downlink control message to a plurality of UEs through a group public downlink control channel, wherein the UEs belong to the same group, the group is obtained by grouping the UEs accessed by a cell according to a preset transmission strategy, and the group public downlink control message is used for indicating a transmission time interval of the group of UEs so that the UEs acquire the group public downlink control message according to the configuration information of the group public downlink control channel acquired in advance and acquire the transmission time interval according to the group public downlink control message.

Optionally, before the base station has downlink data to send to the UE, the base station needs to send group common downlink control information to the UE, so as to instruct the UE how to receive the downlink data.

Or before the UE has uplink data to send to the base station, the UE needs to acquire the group public downlink control information sent by the base station, so as to send the uplink data to the base station according to the group public downlink control information.

In this step, before the base station transmits downlink data to the UE, or before the UE transmits uplink data to the base station, the base station groups the UEs accessed in the cell according to a preset transmission policy, and at least two groups are separated, where at least one group includes a plurality of UEs.

Optionally, the base station groups the UEs accessed by the cells according to a transmission policy in the prior art.

Optionally, after the base station determines the grouping of the UEs, for a group of UEs, the base station generates configuration information of a group common downlink control channel corresponding to the group of UEs, where the configuration information of the group common downlink control channel is information indicating that the group of UEs obtains the group common downlink control information, and corresponds to the grouping of the UEs, and the configuration information of the group common downlink control channel corresponding to the UEs of different groups is different.

Optionally, after determining the configuration information of the group common downlink control channel of a group of UEs, the base station sends the configuration information of the group common downlink control channel to the group of UEs.

Optionally, the base station sends the configuration information of the group public downlink control channel in a prior art manner.

Optionally, after the base station sends the configuration information of the group common downlink control channel, the base station sends a group common downlink control information to the UEs of the group, that is, the base station sends a group common downlink control information corresponding to the group to each UE in the group with the granularity of the group,

it can be understood that, unlike the prior art that the group common downlink control information corresponding to each UE is sent to each UE with a single UE as granularity, in this step, only one group common downlink control information is sent for a group of UEs, so that resources occupied by the group common downlink control information can be saved.

For example, if a group includes 2 UEs, the base station only needs to send one group common downlink control information to the 2 UEs of the group. Compared with the prior art, one group public downlink control information is sent for 1 UE, and two group public downlink control information is needed to be sent for 2 UEs respectively.

Optionally, the UE monitors a group common downlink control channel, acquires the group common downlink control information according to configuration information of the group common downlink control channel acquired in advance, and acquires the transmission time interval according to the group common downlink control information, where the group common downlink control information is used to indicate the transmission time interval, and the UE receives downlink data of the base station according to the transmission time interval, or sends uplink data to the base station.

Alternatively, the transmission time interval is determined by the base station according to the current network situation, and may be determined in a manner of the prior art.

Optionally, the group common downlink control information is sent to a group of UEs by the base station with the group as a scheduling granularity, where the UE may obtain the group common downlink control information, and UEs in other groups of the cell may not obtain the group common downlink control information sent by the base station.

It can be understood that, because the set of UEs obtain the configuration information of the set of common downlink control channels in advance, after the set of UEs detect the set of common downlink control information, the set of UEs can parse and obtain the content of the set of common downlink control information according to the configuration information of the set of common downlink control channels, but the set of UEs that do not obtain the configuration information of the set of common downlink control channels cannot detect the set of common downlink control information, or the set of common downlink control information cannot parse and obtain the content of the set of common downlink control information, thereby ensuring that each set of UEs can obtain the set of common downlink control information corresponding to the set of UEs.

The transmission processing method provided in this embodiment has at least the following technical effects:

and sending a group public downlink control message to a plurality of UE (user equipment), so that the UE can acquire the group public downlink control message according to the configuration information of the pre-acquired group public downlink control channel and acquire the transmission time interval according to the group public downlink control message, thereby saving resources occupied by sending the group public downlink control message.

On the basis of the foregoing embodiments, the method for transmission processing provided by the embodiment of the present invention includes:

transmitting a group public downlink control message to a plurality of UEs through a group public downlink control channel, wherein the UEs belong to the same group, the group is obtained by grouping the UEs accessed by a cell according to a preset transmission strategy, and the group public downlink control message is used for indicating a transmission time interval of the group of UEs so that the UEs acquire the group public downlink control message according to the configuration information of the group public downlink control channel acquired in advance and acquire the transmission time interval according to the group public downlink control message.

There are various grouping modes in the method, and this embodiment will be described by taking one of them as an example.

The group is obtained by grouping the UE accessed by the cell according to a preset transmission strategy, and specifically comprises the following steps:

the group is obtained by grouping the UE according to the service performance requirement information of the UE accessed by the cell.

Optionally, the service performance requirement information of the UE indicates a performance requirement of a service applied by the UE.

Optionally, the service applied by the UE has a certain requirement on the delay performance, and UEs with consistent requirement on the delay performance are grouped into one group, namely, UEs with high requirement on the delay are grouped into one group, namely, UEs with low requirement on the delay are grouped into one group.

For example, a delay budget corresponding to a UE of 100ms may consider that the applied traffic has high delay requirements, and the applied traffic with a delay budget greater than 100ms has low delay requirements.

Correspondingly, the UE with high requirement on the time delay by the service applied by the UE is divided into one group, and the UE with low requirement on the time delay by the service applied by the UE is divided into another group.

It can be understood that the grouping of the UEs is performed according to the service performance requirement information of the UEs, so that the group of the UEs can be obtained more reasonably.

Optionally, the service performance requirement information of the UE may be at least one of: traffic type, bearer type, and QoS (Quality of Service ) class.

Optionally, the base station groups the UEs according to at least one of the above, and obtains configuration information of the corresponding group common downlink control channel.

Optionally, the service type is a service type of the UE application. For example, it may be of the type call, game, data, voice, VOLTE, web page, video, file transfer, low latency high reliability traffic, ultra-large data volume broadband traffic, etc.

It is to be understood that the above service types are merely examples, and are not limited thereto, and may be adjusted according to the service types of the network in practical applications.

Optionally, the base station receives a message sent by the UE and used for requesting to register/use the service, where the message includes a service type, and the base station processes according to the service type and the state of the UE, records the service type of the UE, and groups the UE according to the service type of the UE.

Optionally, if the service performance requirement information of the UE is a service type, the base station groups the UE according to the service type in multiple ways, and two ways are described below as examples.

If the service performance requirement information of the UE is the service type, the base station groups the UE with the same service type or groups the UE with the same service type and performance requirement.

Optionally, for the UE in a cell, the service types of the UE are acquired, and the service types are equally divided into one group, i.e. the service types are divided into one group for calls, the service types are divided into one group for web pages, and so on.

Optionally, the service types of the UE are acquired, and the service types with the same performance requirements are grouped.

Alternatively, the different traffic types may be the same or different in performance requirements.

For example, the performance may be time delay, and the service type is grouped with consistent time delay requirements, i.e. is grouped with high time delay requirements, i.e. is grouped with low time delay requirements.

For example, a delay budget of 100ms may consider that the applied traffic has high latency requirements, and that traffic with a delay budget greater than 100ms has low latency requirements.

Correspondingly, UEs with service types of conversation, game and low-delay high-reliability service are divided into a first group, UEs with service types of data, voice, VOLTE, web page, video, file transmission and ultra-large data volume broadband service are divided into a second group, and it can be understood that the service types of the first group are all services with higher time delay requirements, and the service types of the second group are all services with low time delay requirements.

Alternatively, if the service performance requirement information of the UE is a bearer type, for example, the bearer type of the UE may be RB (radio bearer between the UE and the eNB), S1 bearer (bearer between the eNB and the S-GW), S5/S8 bearer (bearer between the S-GW and the P-GW), default bearer (default bearer), dedicated bearer (dedicated bearer), etc., where the RB is further divided into SRB (Signaling Radio Bearer ) and DRB (Data Radio Bearer, data radio bearer) according to different contents, and further, the SRB is further divided into SRB0, SRB1 and SRB2 according to different messages.

It should be understood that the above bearer types are merely examples, and are not limited thereto, and may be adjusted according to the bearer types of the network in practical applications.

Optionally, the base station receives a message sent by the UE and used for requesting to establish a bearer, where the message includes a bearer type, and the base station processes according to the bearer type and the state of the UE, records the bearer type of the UE, and groups the UE according to the bearer type of the UE.

Alternatively, there are various manners in which the base stations perform grouping, and one will be described as an example.

If the service performance requirement information of the UE is the bearing type, the base station divides the UE with the same bearing type into a group, or divides the UE with the same bearing type and the same performance requirement into a group.

Optionally, for the UE of a cell, the bearer types of the UE are obtained, and the bearer types are grouped identically, i.e. the bearer types are grouped into RB, the bearer types are grouped into S1, and so on.

Alternatively, for radio bearers RB, SRBs and DRBs are classified according to the difference of bearer contents, and from the viewpoint of performance requirements, the performance requirements may be user traffic requirements and Qos levels, and GBR (Guaranteed Bit Rate ) and Non-GBR bearers may be classified according to the difference of user traffic requirements and Qos levels.

Optionally, the QoS class is a priority characterizing quality of service, different traffic, different users, different bearers, providing different QoS.

For example, the QoS level of a UE may be multiple levels depending on the standard.

Alternatively, take 3GPP23.401 as an example, qoS classes are 1-9 for 9 types.

It is to be understood that the above QoS levels are merely examples, and are not limited thereto, and may be adjusted according to the QoS levels of the network in practical applications.

The GBR class bearer is used for the service with higher real-time requirement, the scheduler is required to ensure the lowest bit rate for the class bearer, and the QCI (QoS Class Identifier, quality of service scale value) range is 1-4.

Alternatively, GBR is a guaranteed bit rate bearer, with preferential scheduling, the latency may be low.

In contrast, non-GBR class bearer is used for the service with low real-time requirement, the scheduler is not required to ensure the lowest bit rate for the class bearer, and the QCI range is 5-9, so that the Non-GBR does not need to ensure the bit rate, and the time delay is relatively larger after the scheduling priority is close.

Grouping of UEs may be performed according to user traffic requirements and Qos level performance requirements.

Optionally, if the service performance requirement information of the UE is QoS class, the base station receives a message sent by the UE and used for requesting to establish a bearer, where the message includes a bearer type and a QoS class, and the base station processes according to the bearer type, the QoS class and the state of the UE, records the QoS class of the UE, and groups the UE according to the QoS class of the UE.

Alternatively, there are various ways in which the base station performs grouping according to QoS class, and two kinds of them will be described below as examples.

Optionally, for UEs of one cell, the base station groups UEs with the same QoS class or the same QoS class versus performance requirement.

Alternatively, the QoS class of the UE is obtained and the QoS class is the same as a group, i.e. QoS class 1 is a group, qoS class 2 is a group, and so on.

Optionally, the QoS class of the UE is obtained and the QoS class is grouped into a group with the same performance requirements.

Alternatively, different QoS levels may be the same or different for performance requirements.

For example, the performance may be latency, qoS class is grouped with consistent latency requirements, i.e., group with high latency requirements, i.e., group with low latency requirements.

For example, a delay budget of 100ms may consider that the QoS class corresponding to the applied traffic is high in latency requirement, and a QoS class corresponding to the traffic with a delay budget greater than 100ms is not high in latency requirement.

Accordingly, qoS classes 1 and 2 are divided into a first group, and QoS classes 8 and 9 are divided into a second group, and it can be understood that the first group is a service with a higher latency requirement, and the second group is a service with a lower latency requirement.

Other steps of this embodiment are similar to those of the above embodiment, and will not be described in detail.

UE is grouped according to the service type, the bearer type and/or the QoS class, so that UE grouping can be more reasonably obtained.

On the basis of the foregoing embodiment, a method for transmission processing according to still another embodiment of the present invention includes:

There are various ways of determining the transmission time interval in the method, and this embodiment is described by taking one example.

Optionally, the base station determines the set of common downlink control information according to at least one of:

The transmission time interval is determined according to the service performance requirement information of the UE.

Optionally, the traffic applied by the UE has certain requirements on latency performance. The transmission time interval is determined according to the performance requirement of a group of UE-applied services for delay. In one group. The service applied by the UE has various requirements on the time delay, such as 50ms, 100ms, etc., and can select 50ms as the transmission time interval or 100ms as the transmission time interval, which can be adjusted according to actual situations.

Optionally, the service performance requirement information of the UE may be at least one of: traffic type, bearer type, and QoS class.

Optionally, the transmission time intervals of the different groups are different, the values of the transmission time intervals being group dependent.

For example, if the packets are grouped according to the latency requirement of the traffic type, the transmission time interval of the group is related to the latency. For the UEs of the group with high delay requirement, the TTI of the transmitted group is smaller to meet the service requirement, and for the UEs of the group with low delay requirement, the TTI of the transmitted group is larger.

Alternatively, the TTI may be a TTI unit, and the transmission time interval is two parameters of a scheduling interval and a feedback interval.

Alternatively, the scheduling interval may include a downlink traffic channel interval between a downlink control channel and its scheduling, an uplink traffic channel interval between a downlink control channel and its scheduling, and the feedback interval may include an uplink feedback control channel interval between a downlink traffic channel and its corresponding uplink feedback control channel interval between an uplink traffic channel and its corresponding downlink feedback control channel interval.

the transmission time interval is determined according to the service performance requirement information of the UE of the group, and the transmission time interval of the UE of the group which is configured in a targeted manner can be realized.

The method has various acquisition modes of configuration information of the group of common downlink control channels, and three embodiments are taken as examples for illustration.

Optionally, the configuration information of the group common downlink control channel is acquired by the UE according to one of the following manners:

preconfigured information, RRC dedicated signaling, and system messages.

Optionally, the pre-configured information is specified in the protocol, and the UE acquires the configuration information of the group of common downlink control channels according to the pre-configured information.

Optionally, the UE acquires the configuration information of the group common downlink control channel according to the preconfigured information when the UE has not been grouped or has not received the configuration information of the group common downlink control channel after the UE completes initial access without the notification of the base station.

Optionally, the base station uses RRC dedicated signaling to notify configuration information of the group common downlink control channel.

Optionally, the RRC is a connection established by the UE with the base station, carrying signaling of the UE with the base station.

Optionally, the base station informs the configuration information of the group common downlink control channel based on the system message of the group.

Alternatively, the system message is broadcast by the BCCH (Broadcast Control Channel ), which can be periodically broadcast based on the system information of each cell.

the UE can acquire the configuration information of the group public downlink control channel according to the preconfigured information, the RRC dedicated signaling and/or the system information, and monitor according to the configuration information of the group public downlink control channel.

In the method, if the service performance requirement information of the UE is changed, the base station should also adjust the transmission control, and the adjustment modes can be various, and this embodiment is described by taking two examples.

And if the service performance requirement information of the UE is changed, the UE is regrouped according to the changed service performance requirement information of the UE.

Optionally, when the base station discovers that the service performance requirement information of one UE in the group changes, the grouping of the UE is adjusted.

For example, the UE of the first group has a higher requirement for a certain service performance, and the UE of the second group has a lower requirement for a certain service performance, and when the service performance requirement of a certain UE of the first group is reduced, the UE is tuned to the second group.

Optionally, if the service performance requirement information of the UE is changed, the transmission time interval of the group of UEs is reconfigured according to the changed service performance requirement information of the UE.

Optionally, if the service performance requirement information of the UE is changed, the group of the UE may not be changed, and the base station reconfigures the corresponding transmission time interval according to the changed service performance requirement information of the UE.

For example, the UE of the first group has a higher requirement for a certain service performance, and correspondingly, the UE of the first group has a shorter transmission time interval, the UE of the second group has a lower requirement for a certain service performance, and correspondingly, the UE of the second group has a longer transmission time interval, and when the service performance requirement of most UEs in the first group decreases, the transmission time interval of the first group increases.

if the service performance requirement information of the UE changes, the UE is regrouped or the transmission time interval of the group of UE is reconfigured, so that the real-time change is carried out according to the change of the service performance requirement information of the UE, and the real-time and accurate configuration of the transmission time interval for the UE is ensured.

In the method, one group public downlink control information is sent to a plurality of UEs through a group public downlink control channel, and the base station sends the group public downlink control information in various modes.

Optionally, the transmission time interval of a group of UEs is carried in the group common DCI, so that the UEs detect the group common downlink control channel and acquire the group common DCI.

Optionally, the configuration information of the group common downlink control channel is a preset range of a search space of the group common downlink control channel, and correspondingly, the sending, by the group common downlink control channel, one group common downlink control information to the plurality of UEs specifically includes:

and sending a piece of group public downlink control information to a plurality of UE in a group public downlink control channel search space so that the UE can detect in the range of the preset group public downlink control channel search space and acquire the group public downlink control information.

The protocol specifies that the search range for PDCCH blind detection of a UE is called the search space, which is divided into a common search space (Common Search Space, CSS) and a UE-specific search space (UE-specific search space, USS). The common search space is to be detected for all terminals in the cell, and the user-specific search space is for each terminal.

Optionally, the configuration information of the group public downlink control channel is a group public search space corresponding to the UE, so as to indicate a range searched by the UE.

Optionally, the group public search space configures a specific group public search space for different groups, and accordingly, the base station sends group public downlink control information of the group to a group of UEs through the group public search space, so that the UEs search in the group public search space to obtain group public downlink control information of the group.

It can be understood that the embodiment of the invention provides the concept of the group public search space, which is different from the public search space and the UE private search space in the prior art, and by configuring the group public search space for a group of UEs, the searchable range of only the group of UEs is limited, so that the searchable public spaces of a plurality of UEs in a group can be realized, and compared with the private search space in the prior art, the resource is saved.

Optionally, the configuration information of the group common downlink control channel is a preset password of the group common downlink control information, and correspondingly, the sending of the group common downlink control information to the plurality of UEs through the group common downlink control channel specifically includes:

and sending encrypted group public downlink control information to a plurality of UE through a group public downlink control channel, so that the UE decrypts the encrypted group public downlink control information according to the password of the group public downlink control information and acquires the group public downlink control information.

Optionally, the configuration information of the group public downlink control channel is a password corresponding to the UE, so that the group UE decrypts the encrypted group public downlink control information by using the password to obtain group public downlink control information of the group.

Optionally, the password is a password specific to the different group configuration, the passwords of the different group being different.

Correspondingly, the base station encrypts the group public downlink control information by using the password, so that the UE decrypts the encrypted group public downlink control information by using the password to obtain the group public downlink control information of the group.

The protocol specifies that the PDCCH is used to carry DCI for one or more UEs, i.e. the DCI is a UE-specific DCI due to scrambling the DCI with a UE identity C-RNTI that can uniquely identify the UE.

It can be understood that, unlike the prior art that uses the identifier of the UE as the password and uses the UE as the granularity to perform DCI transmission, the embodiment of the present invention configures the password for a group of UEs, so that only the UEs of the group can decrypt the DCI, thereby realizing that a plurality of UEs under the group can obtain the group DCI, and saving resources compared with the dedicated DCI of the UEs in the prior art.

Optionally, the password is an RNTI (Radio Network Tempory Identity, radio network temporary identity).

Optionally, the group common downlink control information is scrambled by using the group RNTI and then sent to UEs of a group.

For example, RNTI1 is the code of the first group of UEs and RNTI2 is the code of the second group of UEs.

Optionally, the UE of a group cannot realize to learn the position of the group common downlink control information, perform continuous blind detection, decode each detected group common downlink control information by using a pre-received password, and when the password is used to decode, the group common downlink control information is the group common downlink control information of the group.

and sending a group public downlink control information or sending an encrypted group public downlink control information to the group public downlink control channel search space, so that the transmission processing can be realized in a targeted manner as long as the group of UE can obtain the group public downlink control information and other UEs can not obtain the group public downlink control information.

The method may be used in various ways to send one group of common downlink control information, and two embodiments are described as examples.

Transmitting a group common downlink control information to a plurality of UEs through a group common downlink control channel, specifically:

and periodically sending a piece of group public downlink control information to the UE through a group public downlink control channel, or regenerating the corresponding group public downlink control information when the transmission time interval of the group is changed, and sending the regenerated group public downlink control information to the UE.

Alternatively, the base station does not have to transmit the group common downlink control information to the plurality of UEs through the group common downlink control channel every transmission time interval.

Optionally, after determining the UE group and the UE acquires the configuration information of the group common downlink control channel, the base station periodically sends the group common downlink control information to the multiple UEs, where the group common downlink control information sent in each period may be the same or different.

Optionally, if the base station determines that the transmission time interval of the group is changed, the base station carries the changed transmission time interval in the corresponding group common downlink control information, that is, regenerates one group common downlink control information, and sends the same to the UE of the group.

Optionally, the base station reconfigures the transmission time intervals of the group of UEs according to a preset rule, and may determine that the transmission time intervals of the group change.

by periodically sending a group common downlink control information to the UE, or when the transmission time interval of the group changes, regenerating the corresponding group common downlink control information and sending the same to the UE, time domain resources for sending the group common downlink control information can be further saved.

In order to more fully understand the technical content of the present invention, the method of transmission processing provided in this embodiment is described in detail on the basis of the above embodiment.

Aiming at the problems in the prior art, the embodiment proposes a strategy for grouping all the UEs in one cell, does not need to perform independent indication, and indicates with the group as granularity. The patent mainly protects a grouping mechanism of terminals in a cell and a transmission processing method based on the group.

Alternatively, the terminal initiating the same kind of service may be classified into a group for example, and the group common downlink control information is configured as a scheduling interval for example.

The invention provides a scheduling and feedback interval configuration method based on groups, which groups the terminals in a cell according to the reference indexes such as the load established by the terminals in the cell and/or the initiated service types and/or the QOS level of the load. And scheduling and configuring feedback intervals by using common DCI in a group unit for terminals in different groups. Resource waste can be reduced, and terminals with close business in a cell can be uniformly configured in a semi-static mode.

The method of the present invention is as follows.

(1) And grouping the terminals in the cell according to the reference indexes such as the bearer established by the terminals in the cell and/or the initiated service type and/or the QOS level of the bearer. Terminals with the same or similar bearer/service type/QOS class are grouped.

And for the terminals in the same group, detecting and decoding the group public DCI through the configuration information of the group public downlink control channel to obtain corresponding scheduling and feedback interval configuration information units. Specifically, the configuration information of the group common downlink control channel may be a group common downlink control channel search space or a group common RNTI specific to different groups, and the terminal detects and decodes the group common DCI through the group common downlink control channel search space or the group common RNTI to obtain a corresponding scheduling and feedback interval configuration information unit.

Further, the specific downlink control channel search space or RNTI may be notified by RRC dedicated signaling or group-based system messages.

It should be noted that the group common downlink control channel need not be transmitted every TTI, and may be transmitted periodically or when the current group scheduling and feedback interval configuration information element changes.

(2) After the initial access is completed, if the terminal has not received the configuration information of the group common downlink control channel, a pre-configured scheduling and feedback interval configuration information unit is adopted, or the initial value of the information unit is configured in a cell-level system message (MIB/SIBs).

(3) Further, if the bearer/service type/QOS class of the terminal in the group changes, or the information reported by the terminal (such as BSR, PHR, etc. control units) is referred, the base station may change the configuration information of the group common downlink control channel of the individual/part of the terminals through RRC dedicated signaling or based on the system message of the group, so that the terminals may be switched to other groups or newly create a new group, and the part of terminals may obtain the interval value indicated by the new scheduling and feedback interval configuration information unit.

Meanwhile, the base station can change the scheduling and feedback interval configuration information unit according to the bearing/service type/QOS grade condition of the terminals in each group, trigger one or more times of group public downlink control channel transmission, and the terminals obtain the updated configuration value through detecting the group public search space or the group public RNTI.

(1) And grouping the terminals in the cell based on the service, and configuring a scheduling feedback interval information unit based on the group, so that time domain resources can be saved.

(2) The terminal adopts a pre-configured or system information indicated scheduling and feedback interval in the initial access stage, fully considers the scheme when not grouping, and supplements the parts not related in the prior art.

(3) The group where the terminal is located is reconfigured based on the terminal service change, meanwhile, the scheduling feedback interval of the current group terminal can be reconfigured according to the actual condition of the terminal in the group, the complex condition of the current network is comprehensively considered, and the part which is not related in the prior art is supplemented.

Fig. 2 is a schematic structural diagram of an apparatus for transmission processing according to still another embodiment of the present invention.

Referring to fig. 2, on the basis of the above embodiment, the apparatus for transmission processing provided in this embodiment includes a sending module 21, where:

the sending module 21 is configured to send a group common downlink control information to a plurality of UEs through a group common downlink control channel, where the UEs belong to the same group, the group is obtained by grouping UEs accessed by a cell according to a preset transmission policy, the group common downlink control information is used to indicate a transmission time interval of the group of UEs, so that the UEs acquire the group common downlink control information according to configuration information of a pre-acquired group common downlink control channel, and acquire the transmission time interval according to the group common downlink control information

Optionally, before the sending module 21 sends the downlink data to the UE, the group common downlink control information needs to be sent to the UE to instruct the UE how to receive the downlink data.

Or, before the UE has uplink data to send to, the UE needs to acquire the group common downlink control information sent by the sending module 21, so as to send the uplink data to the sending module 21 according to the group common downlink control information.

Before the sending module 21 sends downlink data to the UE, or before the UE sends uplink data to the sending module 21, the sending module 21 groups the UEs accessed by the cell according to a preset transmission policy, and at least two groups are separated, where at least one group includes a plurality of UEs.

Optionally, the sending module 21 groups the UEs of the cell access according to a transmission policy in the prior art.

Optionally, after the sending module 21 determines the grouping of the UEs, for a group of UEs, the sending module 21 generates configuration information of a group common downlink control channel corresponding to a group of UEs, where the configuration information of the group common downlink control channel is information indicating that the group of UEs obtain the group common downlink control information, and corresponds to the grouping of the UEs, and the configuration information of the group common downlink control channel corresponding to the UEs of different groups is different.

Optionally, after determining the configuration information of the group common downlink control channel of a group of UEs, the sending module 21 sends the configuration information of the group common downlink control channel to the group of UEs.

Optionally, the sending module 21 sends the configuration information of the group common downlink control channel in a prior art manner.

For example, if a group includes 2 UEs, the transmitting module 21 only needs to transmit one group common downlink control information to the 2 UEs of the group. Compared with the prior art, one group public downlink control information is sent for 1 UE, and two group public downlink control information is needed to be sent for 2 UEs respectively.

Optionally, the UE listens to a group common downlink control channel, acquires the group common downlink control information according to configuration information of the group common downlink control channel acquired in advance, and acquires the transmission time interval according to the group common downlink control information, where the group common downlink control information is used to indicate the transmission time interval, and the UE receives downlink data of the sending module 21 according to the transmission time interval, or sends uplink data to the sending module 21.

Alternatively, the transmission time interval may be determined by the sending module 21 according to the current network situation, in a manner known in the art.

Optionally, the group common downlink control information is sent by the sending module 21 with the group as a scheduling granularity, and the UE may obtain the group common downlink control information, while UEs in other groups of cells cannot obtain the group common downlink control information sent by the sending module 21.
