Description

Resource indication method and device and computer storage medium

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a resource indication method and apparatus, and a computer storage medium.

Background

In a Long Term Evolution (LTE) system, backhaul links between base stations and between a base station and a core network use a wired connection manner, which brings great deployment difficulty and high network deployment cost to operators, and in order to solve the above problems, a third Generation Partnership Project (3 GPP) has initiated research on a wireless relay technology in an LTE-a (LTE-Advanced) standardization stage to provide a solution for a wireless backhaul link.

A Relay Node (RN, Relay Node) is wirelessly connected to an evolved Node B (eNB) cell to which the Relay Node belongs, where the eNB cell to which the Relay Node belongs is called a Donor cell, the eNB to which the Relay Node belongs is called a Donor eNB (DeNB for short), and a network structure introducing the Relay Node is shown in fig. 1, where the network structure includes 3 radio links:

backhaul link between RN and DeNB;

2. an Access link (Access link) between a terminal User Equipment (UE) and the RN;

direct link between UE and eNB.

In an LTE-A relay system, an access link and a backhaul link are subjected to resource multiplexing in a time division mode. In an access link, as shown in fig. 2, the RN configures some fixed subframes (e.g., Multicast-Broadcast Single Frequency Network (MBSFN) subframes), and in these subframes, except for the first X symbols (e.g., X ═ 1, 2), the RN does not transmit or receive data on the access link, and the DeNB may transmit or receive data on symbols after the subframe, so as to implement resource multiplexing of the access link and the backhaul link.

In a New air interface (NR, New Radio) system, the slot format is more Flexible, each slot may include a downlink symbol (DL), a Flexible symbol (Flexible), and an uplink symbol (UL), and compatibility issues for Rel-8 terminals do not need to be considered, so that resource multiplexing with a backhaul link is not needed to be implemented by configuring an MBSFN subframe in an access link, and resource multiplexing at a slot or symbol level of the access link and the backhaul link may be implemented in the NR system. In the resource multiplexing at the symbol level, some symbols in one time slot are reserved by the access link for the use of the backhaul link, so that the backhaul link can only use some symbols in the symbols, and how to indicate the time slot format of the time slot is a problem to be solved.

4) the number of available symbols. Wherein the available symbols are symbols in the first time slot that may be used for data transmission by the first link.

Here, the first symbol index information and the offset index information are used to determine a symbol index of the first available symbol in the slot format corresponding to the first slot format index information.

Referring to fig. 10, a first field of the first indication information represents first slot format index information 10010 (i.e., 18), a second field represents first symbol index information 0011 (i.e., 3), a third field represents offset index information 0001 (i.e., 1), a fourth field represents the number 1001 (i.e., 9) of available symbols, referring to table 1, 10010 represents a slot format corresponding to the slot format index 18, 0011 represents a symbol index 3 of a first available symbol, and 0001 represents a symbol index 1 (i.e., a second symbol) of the first available symbol in the slot format corresponding to the first slot format index information. 1001 denotes the number of available symbols 9. The first indication information indicates that the symbol direction of 9 symbols starting from symbol index 1 is used to indicate the symbol direction of 9 symbols starting from symbol index 3 in the first slot according to the slot format of slot format index 18.

In this example, different slot formats (e.g., a symbol direction from a 1 st symbol to a 6 th symbol, or a symbol direction from a 3rd symbol to an 8 th symbol, or a symbol direction from a 5 th symbol to a 10 th symbol, etc. in one slot format in table 1) may be configured for the same symbol resource (e.g., a 3rd symbol to an 8 th symbol in one slot) by different offset index information.

Optionally, the first indication information further includes first time slot information, where the first time slot information is used to indicate time slot information of the first time slot. The first time slot information comprises time slot index information, wherein the time slot index information is used for indicating the time slot index of the first time slot in a radio frame, or the time slot index information is used for indicating the time slot index of the first time slot in a first indication information indication period. Or the first time slot information includes a parameter k, where the parameter k is used to determine the first time slot, and k is an integer greater than or equal to 0. For example, the first indication information is located in a time slot n, and then the time slot format indicated by the first indication information is the time slot format of a time slot n + k. Or the first slot information comprises a first bitmap, the first bitmap comprises M1 bits, the M1 bits are used for indicating M1 slots from the slot in which the first indication information is located, and the value of a bit in the first bitmap is a first value or a second value; the first indication information is used to indicate a time slot format of a time slot corresponding to a bit taking a first value in the first bitmap, for example, the first bitmap is 0010000, and if the first value is 1 and the second value is 0, 7 time slots corresponding to 7 bits from left to right in the bitmap are a time slot n +0, a time slot n +1, …, and a time slot n +6, where n is a time slot where the first indication information is located, then a time slot applicable to the time slot format indicated by the first indication information is a time slot n + 2.

The above first to fourth examples are described by taking the first device as the base station device and the second device as the relay device, and the method may also be applied to the case where the first device is the relay device and the second device is the base station device, and details are not described here again.
