Detailed Description

The present application is described in further detail below with reference to the accompanying drawings and examples.

In the related art, as shown in fig. 1, MBMS has an independent scheduling and resource allocation manner, and there is no HARQ mechanism, i.e., there is no air interface feedback mechanism. Although a negative acknowledgement mode (UM) Radio Link Control (RLC) entity supports the MTCH/Multicast Control Channel (MCCH) of MBMS, the transmission window length is 0, i.e., no ordering is required, and the transmission is completed. That is, MBMS data is directly broadcast-transmitted through a base station, that is, through RLC UM mode of window 0, and scheduled-transmitted using radio resource mode configured through RRC signaling.

Based on this, an enhancement scheme of multicast/broadcast technology is proposed, mainly focusing on the RLC separation mode, as shown in fig. 2, that is, a transmitting end Packet Data Convergence Protocol (PDCP) entity is used as an anchor point, and the RLC entity carries and separates to execute PTP and PTM flows respectively; through logical channel aggregation, the UE needs only one RLC receiving entity.

The implementation manner of the aggregation of the logic channels mainly comprises the following steps:

(1) UM ptm+acknowledged mode (AM) PTP, as shown in fig. 3, in this implementation, PTM supports only UM, PTP supports AM, and the transmission mode of multicast data may be flexible in selecting PTM or PTP when first transmitted. The UE feeds back RLC status reports through an Uplink (UL) Dedicated Transport Channel (DTCH). The AM RLC entity controls data to be retransmitted through a multicast mode.

(2) AM ptm+am PTP, fig. 4, in this implementation, both PTM and PTP support AM, the RLC status report fed back by the UE through UL DTCH is shared between the two RLC entities, and the network can flexibly choose to perform unicast retransmission through DTCH or multicast retransmission through MTCH.

From the above description, it can be seen that the basic idea of the enhancement of multicast/broadcast technology is: and a PTM sending mode is introduced into the RLC layer, and the MBMS receiving feedback is realized through a PTP feedback mode.

However, the above enhancement scheme is to perform feedback processing of automatic repeat request (ARQ) in the RLC layer, i.e., by introducing ARQ (the function enabling MBMS will have feedback and retransmission capabilities), the network side and the terminal side need to establish new RLC entities (i.e., RLC functions), each RLC entity carrying MBMS transmission needs to configure one RLC AM entity for feedback processing, although in order to reduce complexity of UE side implementation, in the schemes of fig. 3 and 4, only one RLC AM entity receiving MBMS data is established in the UE side.

Based on this, in various embodiments of the present application, HARQ is introduced in the MAC layer, so as to realize feedback and retransmission of MBMS data in the MAC layer through HARQ, thereby reducing RRC signaling overhead, avoiding overhead of a network side and a terminal side in need of establishing a new RLC function body and newly added system complexity, and realizing fast, efficient and effective MBMS data transmission with retransmission guarantee.

On the other hand, the HARQ of the MBMS and the non-MBMS are both user-level, that is, for a certain user, when the user receives MBMS data, the user performs reception feedback through the HARQ of the MBMS, and since the MBMS is transmitted in a broadcast manner, how to reduce feedback overhead and ensure that the network side can timely and accurately obtain the information about whether the user receives a data packet (the reception is ACK and not NACK) is a problem to be solved.

Therefore, an embodiment of the present application provides an information configuration method, which is applied to a terminal, and includes:

receiving RRC signaling sent by a network side, wherein the RRC signaling at least carries at least one HARQ process related information; at least one HARQ process of the at least one HARQ process is for MCH; the relevant information for at least one HARQ process of the MCH includes at least one of:

identification of the HARQ process;

a process mode of the HARQ process;

buffer size of HARQ process;

a feedback mode of the HARQ process;

the HARQ process transmits data and/or resources used in feedback.

In practical application, the terminal may be referred to as UE or user.

The HARQ process for MCH may be referred to as companion HARQ (english may be expressed as join HARQ). In the following description, the HARQ process for MCH will be simply referred to as companion HARQ.

When the terminal accesses a cell, the accompanying HARQ is established. In the data transmission process, it is decided whether or not cell-level MBMS data needs to be distributed to a process of the accompanying HARQ according to whether or not an accompanying HARQ has been established by one terminal, and a feedback waiting state is set. Here, when the companion HARQ is not established, MBMS data at a cell level cannot be distributed to the processes of the companion HARQ.

When establishing HARQ for MCH through RRC signaling, configuring one or more HARQ processes for the terminal through RRC signaling, and if only one HARQ process is configured, using the unique process in the data transmission process; if multiple HARQ processes are configured, the number of all HARQ processes, the sequence of use, or the method of calculating the HARQ processes, the subframe offset used by each HARQ process, the feedback subframe offset, and the like need to be configured.

In practical application, the dedicated signaling of the configuration terminal is used to configure the HARQ process related information for the MCH, such as RRC signaling (e.g., RRC Setup request (english may be expressed as RRC Setup Request), RRC Setup (english may be expressed as RRC Setup), RRC Setup complete (english may be expressed as RRC Setup Complete) message) in the RRC connection (english may be expressed as RRC connection establishment) Setup process, or available RRC signaling in the RRC signaling process of the RRC reconfiguration process (RRC reconfiguration (english may be expressed as RRC Reconfiguration), RRC reconfiguration complete (english may be expressed as RRC Reconfiguration Complete) message).

The identification for the HRAQ process may be a process ID for the terminal to accompany HARQ when receiving MBMS data. In actual application, the accompanying HARQ process of the MBMS may be one HARQ process or a plurality of HARQ processes, and when the accompanying HARQ process is a plurality of HARQ processes, the identity of the accompanying HARQ process includes a process ID array.

For the Time offset of the uplink feedback corresponding to the HARQ process, in practical application, the Time offset may be n Time slots (english may be expressed as Time Slot), n subframes (english may be expressed as subframe), or n radio frames (english may be expressed as frame), where n is an integer greater than or equal to 1. If the Time offset is n subframes, the Slot Index (english may be expressed as Time Slot Index) in the subframe when configuration is needed; if the time offset is n radio frames, a subframe Index (subframe Index) within the radio frame, and a slot Index within each subframe, need to be configured.

In an embodiment, the process mode of the HARQ process includes one of:

an asynchronous mode;

a synchronous mode;

no mode.

Wherein for asynchronous mode, data transmission and feedback is performed through dynamic scheduling indication of a Medium Access Control (MAC) layer. The method is completely and dynamically scheduled, and has flexibility.

For the synchronous mode, the process of the type is used for transmitting data and feedback thereof has a known constraint relation, and the DCI (PDCCH bearing DCI) is not required to be used for scheduling, so that the DCI is saved in the use process.

For the non-mode, one HARQ process does not configure the mode in advance, and when in use, the synchronous mode or the asynchronous mode is selected by the MAC layer according to the actual requirement. That is, for an idle HARQ process, the process mode of the HARQ process is determined at the time of MAC layer scheduling.

The buffer Size information for the HARQ process refers to buffer Size (english may be expressed as Size) configuration information associated with transmission and reception of data for the HARQ process, and in practical application, the information may specifically include: a buffer size (e.g., 10000 bytes) or an Index of a buffer size (e.g., index=1 identifies a buffer size of 10000 bytes) or a class of a buffer size (e.g., class 1 identifies a buffer size of no more than 10000 bytes); maximum buffer time of data in buffer, etc. For the sender, the buffer accompanying the HARQ process is used to store the retransmitted data packet; for the receiver, the buffer is used for storing the data needing retransmission combination, and if one-time receiving is successful, the buffer is not needed. In practical application, in order not to affect the transmission and reception of the process data of the general HARQ (may also be referred to as the common HARQ) (corresponding to the accompanying HARQ in the embodiment of the present application, refer to other HARQ functions other than MBMS, such as an HARQ function for transmitting or receiving PDSCH, including an existing HARQ function for carrying downlink synchronization channel (DL-SCH)/uplink synchronization channel (UL-SCH) in the 5G system), the size of the transmission and reception buffers of the accompanying HARQ process is independently set.

Feedback mode information for HARQ processes refers to correct feedback mode (english may be expressed as Pattern) information received with a single data packet of HARQ. Specifically, the number of times of transmission corresponding to one feedback is 1:1,1:2,1:3, …, and 1:n, wherein 1 represents the number of times of feedback, n represents the number of times of transmission, specifically, 1:1 represents one time of transmission, namely one time of feedback, and 1:3 represents 3 times of feedback. For example, once the data is newly sent, if the receiving end does not receive the data successfully, the receiving end does not feed back NACK until the receiving end receives the data successfully, and then sends an ACK. For the transmitting end, as long as NACK is not received, the data packet is retransmitted within a certain period of time until ACK is successfully received, or the stop time is reached. The "number of transmissions" configured at this time is the maximum number of transmissions (total number of new transmissions+retransmissions). The transmitting end takes the minimum value of the maximum transmitting times and the time period to determine the transmitting times, namely if the maximum transmitting time is reached, the transmitting is stopped even if the transmitting times are not reached.

The information on whether or not the function of the HARQ process is an independent function refers to whether or not the accompanying HARQ function is an independent function. If the HARQ process is an independent functional body, the HARQ process is a process of the HARQ functional body; if the function is not an independent function body, the function is an extension function of the general HARQ function body. At this time, the companion HARQ process is one or several HARQ processes in the generic HARQ functionality.

In the embodiment of the application, by defining the MAC HARQ function aiming at the MBMS, the air interface feedback aiming at the MBMS service is completed in the MAC layer, so that the feedback is not required to be completed in the ARQ layer of the RLC, the protocol stack function is simplified, and the feedback delay is reduced; meanwhile, because the MAC has accurate control on the air interface, accurate feedback control can be realized, and thus, feedback with low overhead of the air interface can be realized.

The resource information used when data and/or feedback is sent to the HARQ process refers to resource mode information of an uplink channel used by uplink feedback of each HARQ process, and through the mode information, the terminal can calculate and obtain the position, the number and the like of uplink radio resources used by uplink feedback of each process.

In practical application, in the case that the process mode of the HARQ process of the RRC signaling configuration includes an asynchronous mode, that is, when the RRC configuration of one or more asynchronous HARQ processes, scheduling through the PDCCH is required, that is, a new PDCCH Order indication (PDCCH Order) needs to be defined.

Based on this, in an embodiment, the method may further include:

Receiving first DCI sent by a network side, wherein the first DCI comprises at least one of the following components:

identification of the HARQ process;

redundancy versions of HARQ processes;

NDI；

modulation schemes such as Quadrature Phase Shift Keying (QPSK), 16-quadrature amplitude modulation (16 QAM), 64-quadrature amplitude modulation (64 QAM), 256-quadrature amplitude modulation (256 QAM), 1024-quadrature amplitude modulation (1024 QAM), etc.;

resource-related information, i.e., indication information of uplink feedback (english may be expressed as PDSCH-to-harq_ feedback timing indicator, used in conjunction with the set of RRC configurations);

scheduling related information of data carried on the MCH;

and the related information of the HARQ feedback.

Wherein, the first DCI is accompanied with the identification of the HARQ process related to HARQ, redundancy version of the HARQ process, NDI, modulation scheme, and resource related information, and the common HARQ (i.e. the HARQ other than MBMS) also has similar information.

The data carried on the MCH is the MBMS data of the terminal.

In an embodiment, the relevant information of the data carried on the scheduling MCH may include at least one of the following:

the type of the first DCI; the type of the first DCI characterizes the first DCI to be used for dispatching the data carried on the MCH, namely the first DCI is DCI dispatched by the MBMS data of the terminal;

The effective duration of the first DCI, that is, the Life Cycle of the first DCI (english may be expressed as Life Cycle), may be used for multiple times through one-time DCI scheduling in practical application;

the buffer size of the HARQ process, that is, the buffer indication, may correspond to the at least one buffer size of the RRC signaling configuration in practical application, that is, the buffer size in the first DCI is one buffer size of the at least one buffer size of the RRC signaling configuration; specifically, the first DCI may indicate an identification (such as an index) of a buffer size of an HARQ process, and the terminal may determine a buffer size of an accompanying HARQ process according to the identification of the buffer size of the HARQ process indicated by the first DCI and the at least one accompanying HARQ process buffer size of the at least one accompanying HARQ process configured by the RRC signaling.

In an embodiment, the information about HARQ feedback may include at least one of:

the feedback mode of the HARQ process, that is, the mode of the uplink feedback of the HARQ process, may be used in combination with the configuration of the RRC signaling in actual application, that is, the feedback mode of the HARQ process indicated by the first DCI is one feedback mode of the feedback modes of the HARQ process configured by the RRC signaling; specifically, the first DCI may indicate an identification (such as an index) of a feedback mode of the HARQ process, and the terminal may determine a feedback mode accompanying the HARQ process according to the identification of the feedback mode of the HARQ process indicated by the first DCI and the feedback mode of the HARQ process configured by the RRC signaling;

The resource used when the HARQ process sends data and/or feedback, that is, the radio resource indication used by the uplink feedback of the HARQ process, may be used in combination with the configuration of the RRC signaling in practical application, that is, the resource used when the HARQ process indicated by the first DCI sends data and/or feedback is one of the resources used when the HARQ process configured by the RRC signaling sends data and/or feedback; specifically, the first DCI may indicate an identifier (such as an index) of a resource used when the HARQ process sends data and/or feedback, and the terminal may determine, according to the identifier of the resource used when the HARQ process indicated by the first DCI sends data and/or feedback and the resource used when the HARQ process configured by the RRC signaling sends data and/or feedback, a resource used when the HARQ process sends data and/or feedback.

In the case that the process mode of the HARQ process configured by the RRC signaling includes a synchronous mode, that is, when the RRC signaling configures one or more synchronous HARQ processes, if the uplink resource mode, the buffer mode, and the feedback mode of the RRC signaling configured are determined values (that is, a plurality of optional values), there is no need to define a new PDCCH Order for scheduling; if the above of the RRC signaling configuration is a set of optional parameters, a new PDCC Order needs to be defined, i.e. to be scheduled over the PDCCH.

Based on this, in an embodiment, the method may further include:

the effective duration of the second DCI;

the buffer size of the HARQ process, that is, the buffer indication, may correspond to the at least one buffer size of the RRC signaling configuration in practical application, that is, the buffer size in the second DCI is one buffer size of the at least one buffer size of the RRC signaling configuration; specifically, the second DCI may indicate an identification (such as an index) of a buffer size of an HARQ process, and the terminal may determine a buffer size of an accompanying HARQ process according to the identification of the buffer size of the HARQ process indicated by the second DCI and the at least one accompanying HARQ process buffer size of the at least one accompanying HARQ process configured by the RRC signaling;

the feedback mode of the HARQ process, that is, the mode of the uplink feedback of the HARQ process, may be used in combination with the configuration of the RRC signaling in actual application, that is, the feedback mode of the HARQ process indicated by the second DCI is one of the feedback modes of the HARQ process configured by the RRC signaling; specifically, the second DCI may indicate an identification (such as an index) of a feedback mode of the HARQ process, and the terminal may determine a feedback mode accompanying the HARQ process according to the identification of the feedback mode of the HARQ process indicated by the second DCI and the feedback mode of the HARQ process configured by the RRC signaling;

The resource used when the HARQ process sends data and/or feedback, that is, the radio resource indication used by the uplink feedback of the HARQ process, may be used in combination with the configuration of the RRC signaling in actual application, that is, the resource used when the HARQ process indicated by the second DCI sends data and/or feedback is one of the resources used when the HARQ process configured by the RRC signaling sends data and/or feedback; specifically, the second DCI may indicate an identifier (such as an index) of a resource used when the HARQ process sends data and/or feedback, and the terminal may determine, according to the identifier of the resource used when the HARQ process indicated by the second DCI sends data and/or feedback and the resource used when the HARQ process configured by the RRC signaling sends data and/or feedback, a resource used when the HARQ process sends data and/or feedback.

In the case where the process mode of the HARQ process of the RRC signaling configuration includes no mode, that is, when the RRC signaling configures one or more non-mode HARQ processes, it is necessary to determine whether the mode accompanying the HARQ process is a synchronous mode or an asynchronous mode through the PDCCH, so that scheduling is performed through the contents of the first DCI or the second DCI.

Specifically, when the RRC signaling configures that the process mode of the accompanying HARQ process includes a no-mode, when the scheduling is an asynchronous mode through PDCCH, the process mode of the first DCI configuring the HARQ process includes an asynchronous mode, and the first DCI further includes the process mode of the HARQ process; when the scheduling is the synchronous mode through the PDCCH, the process mode of the HARQ process is configured by the second DCI, wherein the process mode of the HARQ process comprises the synchronous mode, and the second DCI also comprises the process mode of the HARQ process.

For the first DCI and the second DCI, the network side scrambles the PDCCH by using an RNTI corresponding to the MCH, that is, scrambles the PDCCH (i.e., a new PDCCH order) by using an RNTI (e.g., group RNTI (G-RNTI)) dedicated to the MBMS, the terminal blindly inspects the PDCCH, and the terminal descrambles the PDCCH by using an RNTI corresponding to the MCH to obtain corresponding DCI, and through the RNTI, the UE identifies the PDCCH order and analyzes the DCI to obtain corresponding configuration information.

Correspondingly, the embodiment of the application also provides an information configuration method which is applied to the network equipment, (particularly a base station), and the method comprises the following steps:

Here, in an embodiment, in a case where the process mode of the RRC signaling configured HARQ process includes a no-mode, the process mode of the first DCI configured HARQ process includes an asynchronous mode, and the first DCI further includes the process mode of the HARQ process.

In an embodiment, in case that the process mode of the HARQ process of the RRC signaling configuration includes a synchronization mode, the method may further include:

In an embodiment, the method may further comprise:

and scrambling PDCCH carrying the corresponding DCI by utilizing the RNTI corresponding to the MCH.

In practical application, for a new MBMS data packet, the network device schedules the new data packet by the PDCCH scheduling, and at this time, the network device sends the new data packet to an air interface, and multiple terminals (terminals that need to receive MBMS data) blindly detect the PDCCH order, where the PDCCH order uses an RNTI dedicated for MBMS for scrambling. And the terminal identifies the PDCCH order through the RNTI, analyzes the DCI to obtain corresponding configuration information so as to receive the MBMS new data packet.

For MBMS retransmission packets, the following two methods may be used for transmission:

The first mode uses the multicast mode of MBMS, the retransmission data packet and the new transmission data packet use the same air interface resource (the time-frequency domain resource is the same) to send to the air interface, if the terminal receives successfully, the terminal does not receive the data packet on the resource; if the UE does not receive successfully, the data packet is received again.

In the second mode, the terminal uses the point-to-point transmission of the terminal-dedicated accompanying HARQ process, and the terminal receives the MBMS data, and if the network side does not receive the ACK fed back by the UE, the terminal retransmits until the transmission is finished.
