Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting downlink shared channel information.
Background
The existing wireless private network communication system works at a 230MHz frequency point, the frequency spectrum resource of the existing wireless private network communication system consists of a plurality of discrete narrow-band bandwidths of 25kHz, the interval of sub-carriers is 2kHz, and each sub-band totally comprises 11 sub-carriers. The radio frame period of the system is 25ms, the radio frame period is divided into 5 subframes, and the subframes are numbered as 0-4 in sequence. Wherein, the subframe 0 is a downlink subframe, the subframe 1 is a special subframe, and the others are uplink subframes. Taking the sub-band i as an example, the frame structure of the wireless private network is shown in fig. 1, and a Downlink Control Channel (PDCCH) and a Downlink Shared Channel (PDSCH) are transmitted in the same frame.
In the existing multi-subband communication system, the PDCCH and the PDSCH are transmitted in the same frame. However, the scheme does not consider that different service requirement types exist in the wireless private network communication system, and the requirements of different requirements on storage, reliability and time delay are different. If the PDCCH period is short and the PDSCH traffic is not large, the PDSCH and the PDCCH are transmitted in the same frame, the PDSCH traffic can be effectively transmitted in a short time, and the requirement of millisecond-level fine control traffic with the traffic of tens of bytes can be met. However, for a service with low delay requirement and large traffic volume or a terminal with weak coverage enhancement, the period of the PDCCH may be long, and if the PDCCH and the PDSCH are transmitted in the same frame, the terminal needs to completely receive PDCCH Information and perform blind detection to obtain Downlink Control Information (DCI) to detect the PDSCH. Fig. 2 is a diagram illustrating transmission of the same frame when PDCCH-numrepetition is 8 and PDCCH-StartF is 1, that is, the PDCCH period is 8, and it can be seen that the PDSCH data of the first 8 frames are buffered, and the size and cost of the terminal are greatly increased.
In summary, in the existing multi-subband communication system, the PDCCH and the PDSCH are transmitted in the same frame, and when the terminal is in a weak coverage scene or the terminal is insensitive to delay and has a large traffic, the PDCCH period is long, and the terminal can detect the PDSCH message only after the DCI information in the PDCCH is completely decoded. While DCI information needs to be detected blindly in the search space, which takes a long time. Therefore, the existing PDCCH and PDSCH transmission scheme requires that the terminal buffer a large amount of PDSCH data under such a condition, which increases the cost and volume of the terminal.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 3 is a flowchart illustrating a method for transmitting downlink shared channel information according to an embodiment of the present invention.
The method for transmitting downlink shared channel information provided by the embodiment of the present invention is applied to a base station, and as shown in fig. 3, the method includes the following steps:
s11, sending multi-subband starting control information to a terminal, wherein the multi-subband starting control information comprises the maximum repetition times of a PDCCH and PDCCH period factors;
specifically, the multi-subband starting control information is DCI information, and is sent to the terminal through a downlink control channel to instruct the terminal to perform multi-subband service transmission.
The time domain period of a PDCCH (physical downlink control channel) of a multi-subband terminal of a wireless private network communication system is given by PDCCH-NumRepetitions and PDCCH-StartF by two parameters. The PDCCH-numrepetition is the maximum number of repetitions of the PDCCH, and takes a frame as a unit, and the value is {1,2,4,8,16}, which indicates the number of radio frames occupied by each downlink control information transmission. PDCCH-StartF is a PDCCH cycle factor, and takes a value of {1,2,4,8,16,32,48,64}, and represents a ratio of the control information to the entire cycle in one scheduling, and if the cycle factor is 2, the control information occupies 1/2 of the entire scheduling cycle. The time domain period of the PDCCH is the product of the two, i.e., the time domain period T of the PDCCH is PDCCH-NumRepetitions × PDCCH-StartF.
The maximum repetition times and PDCCH cycle factors of a PDCCH are carried in multi-subband starting control information sent by a base station to a terminal so as to indicate the position of the terminal for receiving downlink control channel information and downlink shared channel information.
S12, sending downlink control channel information and downlink shared channel information to a terminal in the same frame according to the downlink control channel period, or sending the downlink shared channel information to the terminal in the next frame after the downlink control channel information is sent.
Specifically, if the downlink control channel period is short, the downlink control channel information can be demodulated in a short time, and a large amount of buffer storage of the downlink shared channel information is not caused, then a PDCCH and PDSCH may be transmitted in the same frame. If the downlink control channel period is large, it takes a long time to demodulate PDCCH information, and DCI information in the PDCCH is detected, a large amount of downlink shared channel information is buffered, so the base station resets the transmission mode and transmission time of the PDSCH, and starts to transmit information of the downlink shared channel in the next frame after the downlink control channel transmission is finished according to the time domain period of the PDCCH.
The method for transmitting the downlink shared channel information provided by the embodiment of the invention is applied to a base station, the sending time of the downlink shared channel service is determined according to the downlink control channel period, and when the downlink control channel period is longer, the downlink shared channel information is sent to the terminal in the next frame after the downlink control channel information is sent, so that the buffer of PDSCH data can be reduced, and the cost and the volume of the terminal are reduced.
On the basis of the above embodiment, step S12 includes:
if the period of the downlink control channel is 1, sending downlink control channel information and downlink shared channel information to the terminal in the same frame;
and if the downlink control channel period is greater than 1, transmitting the downlink shared channel information to the terminal in the next frame after the downlink control channel information is transmitted.
Fig. 4 shows a schematic diagram of sending a downlink control channel and a downlink shared channel in the same frame under the condition that the PDCCH period is 1 according to the embodiment of the present invention.
Referring to fig. 4, when the downlink control channel period is 1, that is, PDCCH-NumRepetitions is 1 and PDCCH-StartF is 1, the downlink control channel and the downlink shared channel are transmitted in the same frame.
Fig. 5 shows a schematic diagram that when the PDCCH period is 8, the downlink shared channel starts to be transmitted in the next frame where the downlink control channel ends according to the embodiment of the present invention.
Referring to fig. 5, an example when PDCCH-numrepetition is 4 and PDCCH-StartF is 2, i.e., T is 8, the downlink shared channel starts to be transmitted in a frame next to a downlink control channel end. It should be noted that the remaining resources of the frame for transmitting the PDCCH in fig. 5 may be used for downlink subframes of other UEs, or the resources may be idle.
On the basis of the above embodiment, the period of the downlink control channel is equal to the product of the maximum repetition number of the PDCCH and the PDCCH period factor.
Fig. 6 is a flowchart illustrating a method for transmitting downlink shared channel information according to an embodiment of the present invention.
The method is applied to a terminal, and as shown in fig. 6, the method comprises the following steps:
s21, receiving multi-subband starting control information sent by a base station, wherein the multi-subband starting control information comprises the maximum repetition times of a PDCCH and PDCCH period factors;
specifically, the terminal receives multi-subband starting control information sent by the base station, wherein the multi-subband starting control information is DCI information and includes the maximum repetition number of a PDCCH and a PDCCH cycle factor.
S22, calculating the period of the downlink control channel according to the maximum repetition times of the PDCCH and the PDCCH period factor;
specifically, the time domain period of the PDCCH is the product of the maximum repetition number of the PDCCH and a PDCCH periodicity factor.
S23, receiving the downlink control channel information and the downlink shared channel information in the same frame according to the downlink control channel period, or starting to receive the downlink shared channel information in a frame next to the frame where the downlink control channel information is received.
Specifically, if the downlink control channel period is short, the terminal may cache a large amount of downlink shared channel information, the base station side transmits in the same frame by using the PDCCH and the PDSCH, and the terminal receives the downlink shared channel information in the same frame in which the downlink control channel information is received. If the period of the downlink control channel is small, in order to avoid causing the terminal to cache a large amount of downlink shared channel information, the base station side resets the transmission mode and the transmission time of the PDSCH, and starts to transmit the information of the downlink shared channel in the next frame after the transmission of the downlink control channel is finished, and the terminal starts to receive the information of the downlink shared channel in the next frame after the reception of the downlink control channel is finished according to the time domain period of the PDCCH.
The method for transmitting the downlink shared channel information provided by the embodiment of the invention is applied to a terminal, and the downlink shared channel information is received in the next frame after the downlink control channel information is received when the downlink control channel period is longer by determining the receiving time of the downlink shared channel service according to the downlink control channel period, so that the buffering of PDSCH data can be reduced, and the cost and the volume of the terminal can be reduced.
On the basis of the foregoing embodiment, step S23 specifically includes:
if the downlink control channel period is 1, receiving the downlink control channel information and the downlink shared channel information in the same frame;
and if the downlink control channel period is greater than 1, starting to receive the downlink shared channel information in a frame next to the frame where the downlink control channel information is received.
Specifically, when the PDCCH period is 1, a schematic diagram of the same-frame reception of the downlink control channel and the downlink shared channel refers to fig. 4; when the PDCCH period is greater than 1, the schematic diagram of the downlink shared channel starting to receive in the next frame where the downlink control channel ends refers to fig. 5, which is not described herein again.
On the basis of the foregoing embodiment, step S22 specifically includes:
and calculating the product of the maximum repetition times of the PDCCH and the PDCCH period factor to obtain the period of the downlink control channel.
Specifically, the downlink control channel period is equal to a product of the maximum repetition number of the PDCCH and the PDCCH period factor.
