BRIEF DESCRIPTION OF THE DRAWINGS The technical solutions in the embodiments of the present invention will be described in detail with reference to the accompanying drawings. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative work are within the scope of the present invention.

The embodiment of the present invention provides a communication method for an eNB of a periodic service. As shown in FIG. 1 , the method includes: Step 101: Send a periodic uplink resource scheduling parameter to a UE, so that the UE determines the transmission uplink according to the periodic uplink resource scheduling parameter. The uplink resource scheduling mode of the data, the periodic uplink resource scheduling parameters include: the location of the uplink resource in the time domain dimension, the frequency domain dimension, and the transmission format of the uplink data;

Specifically, on the eNB side, the foregoing periodic uplink resource scheduling parameter is directly sent to the UE. Upstream The location of the resource in the time domain dimension can be determined by the system frame number and the subframe number. Specifically, the system frame number and the subframe number value are calculated according to the following formula: [(SFN* 10)+(subframe number)] mod (Periodicity ) = PeriodicOffset, as shown in Figure 9, where SFN is the System Frame Number (SFN), subframe number is the sub-number, and Periodicity is the period. PeriodicOffset is the offset value in the period, and mod is the number. The operand that divides the remainder. Here, the number of bits of the SFN needs to be expanded. When the SFN is extended to 20 bits, an SFN polling period is 2 ^2Q = 174.8 minutes, which can indicate a service with a period of no more than 174.8 minutes. The location of the uplink resource in the frequency domain is indicated by an index of a physical resource block (PRB), which can be represented by a bitmap of the PRB, and the bit 1 indicates that the PRB is a configured periodic uplink resource, bit 0. Indicates that the PRB is not a configured periodic uplink resource; or the portion between the starting PRB index value and the ending PRB index value indicates the configured periodic uplink resource. The transmission format of the uplink data includes a Modulation Coding Scheme (MCS), and may also include other transmission parameters, such as a Transmitted Power Control (TPC), a Redundant Version (RV), and a reference signal. The cyclic shift offset, whether a non-periodic feedback channel quality indicator (CQI) „ Step 102, receiving uplink data sent by the UE.

The UE sends the periodic uplink resource scheduling parameters to the UE, so that the UE determines the uplink resource and the transmission format for transmitting the uplink data according to the periodic uplink resource scheduling parameter, and does not need to detect the PDCCH, thereby reducing the complexity of resource scheduling and enabling the UE. More energy saving.

The embodiment of the present invention further provides a UE communication method for a periodic service. As shown in FIG. 2, the method includes: Step 201: Receive a periodic uplink resource scheduling parameter sent by an eNB, and determine, according to the periodic uplink resource scheduling parameter, the uplink data to be transmitted. The uplink resource scheduling parameter includes: an uplink resource in a time domain dimension, a frequency domain dimension, and an uplink data transmission format; specifically, the periodic uplink resource scheduling parameter is the same as the foregoing embodiment, This will not be repeated here. Step 202: Send uplink data to an eNB. The transmission format of the uplink data transmits uplink data to the eNB. And the transmission format does not need to detect the PDCCH, thereby reducing the complexity of resource scheduling and making the UE more power-saving.

Based on the communication method of the foregoing cyclic service, the communication process between the eNB and the UE is taken as an example to further describe the communication method of the periodic service according to the present invention. As shown in FIG. 3, the method includes the following steps:

Step 302: The eNB sends a periodic uplink resource scheduling parameter and a downlink resource scheduling parameter to the UE, so that the UE determines an uplink resource and a transmission format for transmitting uplink data and transmits downlink data according to the periodic uplink resource scheduling parameter and the downlink resource scheduling parameter. The downlink resource scheduling parameters include: the location of the uplink resource in the time domain dimension, the frequency domain dimension, and the uplink data transmission format, and the downlink resource scheduling parameters include: the location of the downlink resource in the frequency domain dimension And the transmission format of the downlink data.

Specifically, the periodic uplink resource scheduling parameter or/and the downlink resource scheduling parameter are sent to the UE through a high-level Radio Resource Control (RRC) signaling; when the periodic uplink resource scheduling parameter or/and the downlink resource scheduling parameter is updated. And transmitting, by the radio resource control RRC reconfiguration signaling, the updated periodic uplink resource scheduling parameter or/and the downlink resource scheduling parameter to the UE. The method for defining a specific resource scheduling parameter is the same as that of the foregoing embodiment, and details are not described herein again. The eNB may also send only periodic uplink resource scheduling parameters and not send downlink resource scheduling parameters.

Optionally, the location of the uplink resource or the downlink resource in the frequency domain dimension is obtained by means of random mapping. Specifically, as shown in FIG. 10, multiple physical resource block PRB locations are configured for the UE by using radio resource control RRC signaling; each PRB location is selected as an uplink resource or a downlink resource for the UE according to a random function in multiple PRB locations in each period. ;

The above random function is: Y _K = (Ax Y _K — J mod D

Z _v = Ύ _ν mod N PDSCH -BLOCK where NpDscHiocK is the number of PB locations of the physical resource block, K is the number of subframe identifiers, and the value is 0 Κ 9 , where Υ ₄ is the identity of the UE, ie nRN _TI , specific

, Α and D are relatively large prime numbers, usually A=39827, D=65537, mod is the operator of the remainder of the two-digit division, and Z is the position index of the physical resource block PRB. Similarly, other rules may be used to ensure that the resources occupied by the UEs in the same Transmission Time Interval (TTI) according to the random function do not overlap.

Step 303: The UE receives the periodic uplink resource scheduling parameter and the downlink resource scheduling parameter sent by the eNB, and determines, according to the periodic uplink resource scheduling parameter and the downlink resource scheduling parameter, the uplink resource and the transmission format for transmitting the uplink data, and the downlink resource and the downlink data for transmitting the downlink data. The transmission format, the periodic uplink resource scheduling parameters include: the location of the uplink resource in the time domain dimension, the frequency domain dimension, and the transmission format of the uplink data, and the downlink resource scheduling parameters include: the location of the downlink resource in the frequency domain dimension and the downlink data. Transport format.

Specifically, the radio resource control RRC signaling receives the periodic uplink resource scheduling parameter and/or the downlink resource scheduling parameter sent by the eNB; when the periodic uplink resource scheduling parameter and/or the downlink resource scheduling parameter is updated, the RRC is controlled by the radio resource. Reconfiguration signaling receives updates sent by the eNB

The UE may also receive only periodic uplink resource scheduling parameters and not receive downlink resource scheduling parameters.

Step 304: The UE sends uplink data to the eNB. The source transmits uplink data to the eNB in the time domain dimension, the location on the frequency domain dimension, and the transmission format of the uplink data.

Step 305: The eNB receives uplink data sent by the UE. Step 306: After receiving the uplink data sent by the UE and sending the downlink resource scheduling parameter to the UE, the eNB feeds back the joint indication information to the UE, where the joint indication information includes an uplink retransmission indication and a downlink indication, where the uplink retransmission indication is used to indicate whether there is an uplink. The data needs to be retransmitted, and the downlink indication is used to indicate whether there is downlink data to be transmitted.

Specifically, the uplink retransmission indication is ACK/NACK, the ACK is Acknowledgement, that is, there is no uplink data to be retransmitted, and the NACK is Negative Acknowledgement, that is, the uplink data needs to be retransmitted, where one bit is Indicates the ACK/NACK result and the other bit indicates the downlink indication. If no uplink data needs to be retransmitted, the configured uplink resources are scheduled to be used by other UEs in this period.

Step 307: The UE receives the joint indication information fed back by the eNB, where the joint indication information includes an uplink retransmission indication and a downlink indication, where the uplink retransmission indication is used to indicate whether uplink data needs to be retransmitted, and the downlink indication is used to indicate whether downlink data needs to be transmitted. .

Specifically, the UE determines, according to the joint indication information, whether uplink data needs to be retransmitted and whether downlink data needs to be transmitted. If no uplink data needs to be retransmitted and no downlink data needs to be transmitted, the UE directly shuts down the transceiver and enters a sleep state until the next cycle.

Step 308: If the uplink data needs to be retransmitted, the UE, after receiving the joint indication information fed back by the eNB, retransmits the uplink data to the eNB according to the location of the uplink resource in the frequency domain dimension and the transmission format in the uplink resource scheduling parameter.

Step 309: If there is uplink data to be retransmitted, the eNB receives the uplink data retransmitted by the UE. If no uplink data is required to be retransmitted, the configured uplink resources are scheduled to be used by other UEs (mainly other UEs of non-cyclical services) in this period.

Step 310: If downlink data needs to be transmitted, the eNB sends downlink data to the UE after feeding back the joint indication information to the UE.

Specifically, if the downlink resource scheduling parameter is sent to the UE, the downlink resource is sent according to the downlink resource scheduling parameter in the frequency domain dimension and the downlink data transmission format; if the downlink resource scheduling parameter is not sent to the UE, Sending downlink resources by means of PDCCH The location in the frequency domain dimension and the transmission format of the downlink data and send downlink data to the UE. The downlink data may include one or any combination of the following: updated periodic uplink resource scheduling parameters, updated downlink resource scheduling parameters, and service data.

Step 311: If there is downlink data to be transmitted, the UE receives the downlink data sent by the eNB after receiving the joint indication information fed back by the eNB.

Specifically, if the UE receives the downlink resource scheduling parameter sent by the eNB, when the UE receives the joint indication information fed back by the eNB in the mth subframe, the downlink resource and the transmission determined according to the downlink resource scheduling parameter in the m+k subframe. The format receives the downlink data sent by the eNB, where k represents the necessary preparation time, and in the Frequency Division Duplexing (FDD) system, generally k=4; if the UE does not receive the downlink resource scheduling parameter sent by the eNB, the same The UE receives the joint indication information fed back by the eNB in the mth subframe, and detects the PDCCH in the m+k subframe to obtain the location of the downlink resource in the frequency domain dimension and the transmission format of the downlink data, and receives the downlink data sent by the eNB. If the UE receives the new periodic uplink resource scheduling parameter and/or the updated downlink resource scheduling parameter sent by the eNB, the resource determined by the previously received resource scheduling parameter is released in the next cycle, and is determined by using the updated resource scheduling parameter. Resources.

If no downlink data is required to be transmitted, the eNB schedules the configured downlink resources to other UEs (mainly other UEs of non-cyclical services) during the current period.

Step 312: After receiving the downlink data sent by the eNB, the UE feeds back a downlink retransmission indication to the eNB, so that the eNB determines whether downlink data needs to be retransmitted.

Step 313: The eNB receives a downlink retransmission indication fed back by the UE to determine whether downlink data needs to be retransmitted.

Step 314: If there is downlink data to be retransmitted, the eNB retransmits the downlink data to the UE.

Step 315: If there is downlink data to be retransmitted, the UE receives the downlink data retransmitted by the eNB according to the downlink resource scheduling parameter after feeding back the downlink retransmission indication to the eNB.

Specifically, the actions performed by the UE according to the joint indication information are as shown in Table 1.

Table 1: Actions performed by the UE according to the joint indication information Whether the uplink data is heavy or not

Pass (lbit) data (lbit)

ACK NO goes to sleep

ACK YES Receive downlink data

NACK NO retransmits upstream data (detects PDCCH or

Use the configured resources)

NACK YES retransmits upstream data and receives downstream data

(Detect PDCCH or use configured resources)

It should be noted that, in the foregoing embodiment, the UE may also retransmit the data without using the uplink resource and the downlink resource configured by the eNB, but determine the resource and the transmission format by detecting the PDCCH and retransmit the data. The downlink resource scheduling parameter may also include the location of the downlink resource in the time domain dimension, which is the same as the transmission of the uplink data, and may be directly downlinked according to the location in the time domain dimension determined by the downlink resource scheduling parameter. data.
