Currently, time domain resources are allocated in some communication protocols using a time domain resource allocation table. Each row of the current time domain resource allocation table only supports one time domain resource indication type, and as the time domain resource allocation table has 16 rows at most, each row can only correspond to one time domain resource indication value set in a time slot, at most, 16 time domain resource allocation scenes can be supported. If there is an newly added time domain resource allocation scenario, the time domain resource allocation table may not be supported.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present invention, and have no specific meaning per se. Thus, "module," "component," or "unit" may be used in combination.
Example 1
An embodiment of the present invention provides a method for allocating time domain resources, as shown in fig. 1, where the method includes:
s101, acquiring each row of indication data from a time domain resource allocation table;
s102, selecting a time domain resource indicated value set allocated in a time slot according to the acquired indicated data;
s103, distributing time domain resources according to the time domain resource indicated value set distributed in the selected time slot and the time domain resource indicated data distributed in the time slot.
In an embodiment of the present invention, optionally, the indication data includes: scheduling slot indication data, data channel mapping type indication data and time domain resource indication data allocated in a slot.
According to the embodiment of the invention, each row of indication data is obtained from the time domain resource allocation table, and the time domain resource indication value set allocated in the time slot is selected according to the obtained indication data, so that each row of the time domain resource allocation table can support the time domain resource indication value sets allocated in various time slots, and the problem that the number of the time domain resource indication sets in the time slots supported in the time domain resource allocation table is small is solved effectively.
In detail, in 5G, the position and number of OFDM symbols used for transmission are determined by the starting OFDM symbol position and the number of OFDM symbols for which transmission is continued when time domain resources are allocated. The type of time domain resource indication allocated within a time slot (which may also be referred to as the type of time domain resource allocation) is used to represent the allocation scenario of time domain resources. Such as slot-based time domain resource allocation (slot-based time domain resource allocation), non-slot-based time domain resource allocation (mini-slot based time domain resource allocation, or non-slot based time domain resource allocation), and multi-slot-based time domain resource allocation (multi-slot based time domain resource allocation). The time domain resource allocation based on the time slots and the time domain resource allocation based on the non-time slots are time domain resource allocation in one time slot, and the time domain resource allocation based on the time slots is time domain resource allocation on the time slots.
In time domain resource allocation based on a plurality of slots, the time domain resource allocation mode adopted in each slot (slot) is the same, and generally, the time domain resource allocation mode of the first slot in the plurality of slots is used for all the remaining slots. The non-slot time domain resource allocation is limited to the number of OFDM symbols for which transmission is continuous, which may be 2, 4 and 7.
In some communication protocols, indication of time domain resources within each slot in a 5G time domain resource allocation is supported in the form of resource indication values (Resource Indication Value, RIV). The time domain resource indication in the slot is the OFDM symbol used for transmission in the slot. The RIV value refers to a value calculated according to the position of the starting OFDM symbol and the number of transmission continuation OFDM symbols, and the starting OFDM symbol and the transmission continuation OFDM symbol are further represented by the value. In the data transmission process, the number of the initial OFDM symbols and the continuous OFDM symbols can be known through corresponding formula operation according to the received RIV value. The RIV value calculation formula is as follows:
in OFDM start Representing the starting OFDM symbol position, L OFDM Representing the number of continuous OFDM symbols, N OFDM Representing the number of all OFDM symbols for time domain resource allocation.
The time domain resource allocation table is shown in table one, and may include multiple rows of indication data, where the indication data of each row mainly includes three parts of contents: scheduling time slot indicating data K0, time domain resource allocation indicating data in time slots (slots) and data channel mapping type indicating data; wherein the scheduling time slot indication indicates a time slot indication for time domain resource allocation; the data channels may also include transport channels. The contents of these three parts require 2 bits, 6 bits and 1 bit, respectively. Wherein the time domain Resource allocation indication within a time slot is implemented by a Resource indication index (Resource index) indicating a Resource indication value (Resource Indication Value, RIV) in a set of time domain Resource indication values within a corresponding Resource indication time slot.
In the embodiment of the present invention, optionally, the scheduling time slot indication data is data mapped by a bit corresponding to the scheduling time slot indication; the data channel mapping type indication data is data mapped by bits corresponding to the data channel mapping type indication; and the time domain resource indication data allocated in the time slot are mapped data of corresponding bits of the time domain resource indication allocated in the time slot. For example, a row in table one with a table index of 0 indicates that the data is mapped with bits 00, 000011, and 0, respectively.
List one
In the embodiment of the invention, the set of the time domain resource indicated values in the time slot can be shown in a table two.
Watch II
| ROW (Row) | RIV | Combined content |
| 1 | X | Start symbol a, transmission duration symbol B |
| 2 | Y | Start symbol a, transmission duration symbol C |
| …… | …… | …… |
| N | Z | Start symbol K, transmission duration symbol L |
For example, each combination of the starting OFDM symbol and the transmission duration OFDM symbol may be represented by an RIV value independently, and the corresponding RIV value is calculated by using the formula (1-1) for all possible combinations of the starting OFDM symbol and the transmission duration OFDM symbol in each time domain resource allocation scenario, so that the RIV values of all possible combinations of the starting OFDM symbol and the transmission duration OFDM symbol can be obtained, and if there are N RIV values in total, the set of time domain resource indication values in the time slot formed by the N RIV values is shown in table two. The time slot time domain resource indication value sets of different time domain resource allocation conditions are different, for example, the time slot time domain resource allocation and the non-time slot time domain resource allocation respectively correspond to the time slot time domain resource indication value sets.
In the time domain resource allocation of 5G, not only the time domain resource in the slot needs to be indicated, but also the slot to which the time domain resource allocation is performed needs to be indicated. The time domain resource allocation also supports cross-slot scheduling, so that the scenario of cross-slot scheduling is also considered when the time domain resource allocation slot indication is performed. For two types of time domain resource allocation, namely time domain resource allocation based on time slots and time domain resource allocation based on non-time slots, the applied scene is different, so that the two types also need to be indicated when the time domain resource allocation is performed. Since the mapping type of the data channel can distinguish between time-slot-based time-domain resource allocation and non-time-slot-based time-domain resource allocation, the transmission channel type also needs to be indicated at the time of time-domain resource allocation.
Considering that the time slot-based time domain resource allocation, the non-time slot-based time domain resource allocation and the time domain resource allocation based on a plurality of time slots are all indicated by using the same time domain resource configuration table, all possible scenes need to be indicated in the configuration table, so that the time domain resource indication types allocated in various slots need to be indicated. The time domain resource allocation table has 16 rows at most, and each row can only correspond to one time domain resource indication value set in a time slot, so that at most, only the time domain resource indication types allocated in 16 time slots can be supported, and more types can not be supported.
The method in the embodiment of the invention can also be called as a bit coupling indication method, and each row of indication data of the time domain resource allocation table in the embodiment of the invention can indicate the time domain resource indication value set allocated in various time slots, so that the complexity of the time domain resource allocation table is greatly reduced, and more time domain resource allocation scenes and time domain resource indication types allocated in more time slots can be supported. And the number of time domain resource indicated value sets allocated in the time slot supported by each row of indicated data is increased, so that the number of lines required by the time domain resource allocation table is reduced, and the time domain allocation indication overhead is reduced.
In the embodiment of the present invention, optionally, the selecting, according to the obtained indication data, a set of time domain resource indication values allocated in a time slot includes:
selecting one or more kinds of indication data from the acquired indication data;
selecting a time domain resource indicated value set allocated in a time slot corresponding to the selected indicated data according to a preset mapping relation; the mapping relation is the corresponding relation between the indication data and the indication value set of the time domain resource allocated in the time slot.
In the embodiment of the present invention, optionally, selecting, according to a preset mapping relationship, a set of time domain resource indication values allocated in a time slot corresponding to the selected indication data includes:
when the selected indication data is the scheduling time slot indication data, selecting a time domain resource indication value set allocated in a time slot corresponding to the scheduling time slot indication data according to the mapping relation;
when the selected indication data is the data channel mapping type indication data, selecting a time domain resource indication value set allocated in a time slot corresponding to the data channel mapping type indication data according to the mapping relation;
when the selected indication data is the scheduling time slot indication data and the data channel mapping type indication data, selecting a time domain resource indication value set allocated in a time slot corresponding to the combination indication data of the scheduling time slot indication data and the data channel mapping type indication data according to the mapping relation.
In detail, taking a transport channel as an example, when the mapping type of the transport channel indicates that data affects time domain resource allocation in a time slot independently, there are two types of mapping types of the transport channel, namely, a mapping type A of the transport channel and a mapping type B of the transport channel. Wherein the transmission channel mapping type a corresponds to slot-based time domain resource allocation and wherein the transmission channel mapping type B corresponds to mini-slot time domain resource allocation. When the transmission channel mapping type is a, the time domain resource allocation in the time slot is based on the allocation of the time slot, and the corresponding time domain resource indication value set in the time slot is characterized in that each symbol in the time slot can be used as a starting symbol position, and the number of continuous symbols for performing the time domain resource allocation can be all possible symbol numbers from the starting symbol position to the symbol position at the end of the time slot. When the mapping type of the transmission channel is B, the time domain resource allocation in the time slot is based on non-time slot allocation, and the corresponding time domain resource indication value set in the time slot is characterized in that each symbol except for the symbol at the end of the time slot in the time slot can be used as a starting symbol position, and the number of continuous symbols for performing the time domain resource allocation is fixed, namely 2, 4 and 7. The number of persistent symbols is only 2 or 4 if the symbol start position does not satisfy the number of persistent symbols of 7, and is only 2 if the symbol start position does not satisfy the number of persistent symbols of 4.
When the scheduling time slot indication data independently affects the time domain resource allocation in the time slot, four scheduling time slot indication types are used for scheduling in the time slot and spanning multiple time slots respectively. There are three cases in total for scheduling across multiple slots, each configured by RRC signaling. When the scheduling time slot indicates the time slot scheduling, the characteristic of the time domain resource indicated value set in the corresponding time slot at this time is that the control channel indicating the time domain resource scheduling of the data channel and the data channel are positioned in the same time slot, and the starting symbol position and the transmission continuous symbol in the corresponding time slot are affected by the control channel. Since the control channel is also located in the time slot, the control channel will occupy the time domain resources in the time slot. The symbols occupied by the control channel in that slot will not be available for data transmission. When the scheduling time slot indicates cross-time slot scheduling, the characteristic of the time domain resource indicated value set in the corresponding time slot is that the control channel indicating the time domain resource scheduling of the data channel and the data channel are positioned in different time slots, and the initial symbol position and the data transmission symbol in the corresponding time slot are not influenced by the control channel.
When the mapping type indication data and the scheduling time slot indication data of the transmission channel affect the time domain resource allocation in the time slot together, eight situations are totally used. When the mapping type of the transmission channel is A and the scheduling time slot indicates scheduling in the time slot, the corresponding time domain resource indicated value set in the time slot has the characteristics that the initial symbol position and the transmission continuous symbol are affected by the existence of the control channel, and the symbol position for the control channel is not used for data transmission. And the symbol within the slot other than the symbol used for the control channel may be the starting symbol position and the number of transmitted symbols is the number of all possible symbols in the symbol positions from the starting symbol position to the end of the slot. When the mapping type of the transmission channel is B and the scheduling time slot indicates scheduling in the time slot, the characteristic of the time domain resource indicated value set in the corresponding time slot is that each symbol except the symbol at the end of the time slot in the time slot can be used as a starting symbol position, and the number of continuous symbols for performing time domain resource allocation is fixed, namely 2, 4 and 7. The number of persistent symbols is only 2 or 4 if the symbol start position does not satisfy the number of persistent symbols of 7, and is only 2 if the symbol start position does not satisfy the number of persistent symbols of 4. When the mapping type of the transmission channel is A and the scheduling time slot indicates cross-time slot scheduling, the corresponding time slot time domain resource indicated value set is characterized in that the initial symbol position and the transmission duration symbols are not affected by the existence of a control channel, the corresponding time slot time domain resource indicated value set is characterized in that each symbol in the time slot can be used as the initial symbol position, and the number of duration symbols for time domain resource allocation can be the number of all possible symbols from the initial symbol position to the symbol position at the end of the time slot. When the mapping type of the transmission channel is B and the scheduling time slot indicates cross-time slot scheduling, the characteristic of the time domain resource indicated value set in the corresponding time slot is that each symbol except the symbol at the end of the time slot in the time slot can be used as a starting symbol position, and the number of continuous symbols for time domain resource allocation is fixed, namely 2, 4 and 7. The number of persistent symbols is only 2 or 4 if the symbol start position does not satisfy the number of persistent symbols of 7, and is only 2 if the symbol start position does not satisfy the number of persistent symbols of 4.
That is, the method in the embodiment of the present invention may affect the set of time domain resource indication values in the time slot together or separately by scheduling the mapping type indication data of the time slot indication data and the transmission channel.
That is, in the embodiment of the present invention, optionally, allocating time domain resources according to the set of time domain resource instruction values allocated in the selected time slot and the time domain resource instruction data allocated in the time slot includes:
acquiring a resource indicated value corresponding to time domain resource indicated data allocated in a time slot from a time domain resource indicated value set allocated in the selected time slot;
and distributing time domain resources according to the obtained resource indicated value.
In the embodiment of the present invention, optionally, the time domain resource indication data allocated in the time slot is a resource indication index; acquiring a resource indicated value corresponding to time domain resource indicated data allocated in the time slot from the time domain resource indicated value set allocated in the selected time slot, wherein the resource indicated value comprises:
and acquiring a resource indicated value from the time domain resource indicated value set distributed in the selected time slot according to the resource indicated index.
The resource indication index in the embodiment of the invention can be a line number in the table two.
For example, the scheduling time slot indicating data is denoted by D1, the transmission channel mapping type indicating data is denoted by D3, and the time domain resource indicating data in the time slot is denoted by D2; where D2 corresponds to the set of time domain resource indicator values within the time slot.
When the transmission channel map type indicates that the data alone affects the time domain resource allocation indication within the time slot. When d3=0, the set of time domain resource instruction values in the time slot in D2 is the set of time domain resource instruction values in the time slot allocated based on the time slot. When d3=1, the set of time domain resource indicator values in the time slot in D2 is the set of time domain resource indicator values in the time slot based on the non-time slot allocation.
When the scheduling slot indication data alone affects the time domain resource allocation within the slot. When d1=00, the set corresponding to the time-domain resource indication data in the time slot in D2 is the set of time-domain resource indication values in the time slot based on the scheduling in the time slot. When d1=01 or 10 or 11, the set of time domain resource indication values in the time slot in D2 is a set of time domain resource indication values in the time slot based on cross-slot scheduling.
When the transmission channel mapping type and the scheduling slot indication jointly affect the time domain resource allocation in the slot. When d1=00 and d3=0, the set of intra-slot time domain resource instruction values in D2 is a set of intra-slot time domain resource instruction values allocated based on the slot and scheduled within the slot. When d1=00 and d3=1, the set of intra-slot time domain resource instruction values in D2 is a set of intra-slot time domain resource instruction values based on non-slot allocation and intra-slot scheduling. When d1=01 or 10 or 11, d3=0, the set of time domain resource instruction values in the time slot in D2 is a set of time domain resource instruction values in the time slot that is based on the time slot allocation and that is scheduled across the time slots. When d1=01 or 10 or 11, d3=1, the set of time domain resource indication values in the time slot in D2 is a set of time domain resource indication values in the time slot based on non-slot allocation and cross-slot scheduling.
Therefore, in the time domain resource allocation table, D1 and D3 may respectively and individually indicate the set of time domain resource indication values in the time slot in D2, and D1 and D3 may also jointly indicate the set of time domain resource indication values in the time slot in D2, so that each row in the allocation table may support multiple sets of time domain resource indication values allocated in the time slot.
