Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a resource indication method, apparatus, and storage medium.
Background
This section is intended to provide a background or context to the embodiments of the invention that are recited in the claims. The description herein is not admitted to be prior art by inclusion in this section.
In the existing communication system, user equipment-Specific (UE-Specific) manner is generally adopted for user data scheduling, which has the advantages that a base station can allocate appropriate resources to each user based on the channel condition and the service type of each user, and indicate Information such as corresponding time-frequency resource position, Modulation and Coding Scheme (MCS) through UE-Specific DCI (Downlink Control Information). The method can flexibly distribute the system resources and effectively improve the utilization rate of the system resources based on scheduling.
However, in the scenario of a large number of users, resource scheduling based on UE-specific may occupy a large amount of downlink control channel resources. For some specific scenes, such as a high-speed railway, the user density is high, the channel quality and the service type of the user are similar, or an mMTC (mass machine type communication) scene, the user connection number is high, each user data packet is small, the downlink control channel resources can be effectively saved by adopting a multi-user scheduling method, and the scheduling efficiency of a base station is improved.
After receiving the downlink scheduling, the user sends HARQ-ACK (hybrid automatic Repeat request-Acknowledgement) feedback information through an uplink control channel (PUCCH). The base station can pre-configure one or more PUCCH Resource sets for the user, and the selection of a certain PUCCH Resource in a specific set is a mode of explicitly indicating through uplink control channel Resource indication information (PUCCH Resource Indicator) bit information in DCI and simultaneously combining other specific information for implicit indication. When the DCI does not include the uplink control channel resource indication information bit, the implicit indication is performed only through other information.
In the LTE network, the information for implicitly indicating the selection of the PUCCH resource is an index (index) of a starting CCE (Control Channel Element) of DCI scheduling corresponding downlink transmission. However, for the scheduling scheme based on the user group, the downlink resource allocation information of all users is located in the same group-common DCI, that is, the starting CCEindex is consistent for the users in the group, and thus, PUCCH resources of multiple users cannot be further distinguished.

In the embodiment of the invention, a network side configures a user identifier for the UE in advance, and after receiving a downlink control signaling which is sent by the network side and used for indicating at least one user data transmission, the UE can determine the uplink channel resource corresponding to the UE at least according to the user identifier configured by the network side. Specifically, if the downlink control signaling received by the UE is used to indicate downlink data transmission, the UE may determine, according to at least a user identifier configured by the network side, an uplink control channel resource for feeding back HARQ-ACK (hybrid automatic repeat request acknowledgement) from an uplink control channel resource set configured by the network side; and if the downlink control signaling received by the UE is used for indicating uplink data transmission, the UE determines uplink shared channel resources for transmitting the uplink data from the uplink resources scheduled by the received downlink control signaling at least according to the user identification configured by the network side.
In specific implementation, when receiving a downlink control signaling sent by a network side and used for indicating at least one user to perform downlink data transmission, a UE (user equipment) may implement the resource indication method provided in the embodiment of the present invention according to the flow shown in fig. 1, including the following steps:
s11, the UE receives a downlink control signaling sent by the network side for indicating at least one user to transmit downlink data.
The user identifier and the uplink control channel resource set may be configured through RRC (radio resource control) signaling.
In specific implementation, a network side may schedule uplink control channel resource allocation of a group of users through a group-common DCI, and the users in the group may obtain their own uplink control channel resource allocation information through a user identifier configured by an RRC signaling.
S12, UE determines the uplink control channel resource for feeding back HARQ-ACK from the uplink control channel resource set configured by the network side at least according to the user identification configured by the network side.
In a specific implementation, step S12 may be implemented in any of the following manners:
in the first method, the downlink control signaling does not include the uplink control channel resource indication information.
In this embodiment, the PUCCH resource set configured by the base station for each UE collectively includes T PUCCH (uplink control channel) resources available for feeding back HARQ-ACK information, where T is an integer greater than or equal to 1; if the group-common DCI transmitted by the base station does not include the uplink control channel resource indication information, the resource identifier (index) of the PUCCH resource in the PUCCH resource set for feeding back the HARQ-ACK information selected by the nth user may be determined at least by the user identifier of the user.
In specific implementation, the UE may determine the uplink control channel resource for feeding back the HARQ-ACK according to the number of uplink control channels included in the uplink control channel resource set and the user identifier corresponding to the UE.
For example, the UE may determine the uplink control channel resource for feeding back the HARQ-ACK from the uplink control channel resource set according to the following formula:
wherein:
n represents the nth UE in the user group, and n is an integer greater than or equal to 1;
idnrepresenting the user identification corresponding to the nth UE;
and T represents the number of the uplink control channel resources contained in the uplink control channel resource set.
In specific implementation, the user identifier includes at least one of the following: an RNTI (radio network temporary identifier) corresponding to the UE and a user group internal identifier corresponding to the UE.
If the user identity is an RNTI configured by RRC signaling on the network side, the RNTI can comprise a C-RNTI (cell radio network temporary identity), a TC-RNTI, an SPS-RNTI and the like. The index of the uplink control channel resource selected by the UE in the uplink control channel set may be determined according to the RNTI corresponding to the user, for example, the index corresponding to the UE may be determined according to the following formulaIndex of (2):
wherein n isRNTIAnd indicates an RNTI corresponding to the UE.
If the UE identifier is an identifier of the UE in a group in a user group configured by the network side through RRC signaling, the index of the uplink control channel resource selected by the UE in the uplink control channel set may be determined according to the identifier of the UE in the group in the user group, for example, the index corresponding to the UE may be determined according to the following formula:
wherein
Indicating that the UE is identified within a group within a user group.
In the second method, the downlink control signaling includes uplink control channel resource indication information.
In this embodiment, in step S12, the UE may determine the resource identifier for feeding back the HARQ-ACK from the uplink control channel resource set according to the user identifier and the uplink control channel resource indication information. Specifically, the UE may determine the resource identifier for feeding back the HARQ-ACK from the uplink control channel resource set according to the procedure shown in fig. 2:
s21, the UE divides the resource set of the uplink control channel into several subsets according to the bit number occupied by the resource indication information of the uplink control channel.
Assuming that the uplink control channel resource set configured by the network side base station for each UE contains T uplink control channel resources available for feeding back HARQ-ACK in common, and group-common DCI sent by the base station includes uplink control channel resource indication information of k (k is an integer greater than or equal to 1) bits, a resource identifier (index) of the uplink control channel resource selected by the nth UE in the PUCCH resource set for feeding back HARQ-ACK information may be determined at least by the uplink control channel resource indication information and a user identifier of the UE.
S22, the UE determines the corresponding subset identification according to the uplink control channel resource indication information.
In one embodiment, the UE divides the PUCCH resource set configured on the network side into 2kAnd then selecting a corresponding subset according to the bit indication of the uplink control channel resource indication information, for example, the binary uplink control channel resource indication information may be converted into a decimal value, and specifically, the binary uplink control channel resource indication information may be converted into a decimal value according to the following formula: idxsubsetAnd determining the subset identifier corresponding to the UE according to the converted numerical value.
Taking k as 3 and the uplink control channel resource indication information as 101 as an example, the UE may divide the uplink control channel resource set into 8 subsets, the numbers of which are #0 to #7, and may determine that the subset identifier corresponding to the UE is 5 according to the uplink control channel resource indication information, that is, the UE may select a resource for feeding back HARQ-ACK from the uplink control channel resources included in the #5 subset.
And S23, determining the uplink control channel resource for feeding back the HARQ-ACK from the corresponding subset at least according to the user identification according to the determined subset identification.
In the above example, the UE may select the uplink control channel resources for feeding back the HARQ-ACK from the #5 subset.
In specific implementation, the UE may select the uplink control channel resource for feeding back the HARQ-ACK from the corresponding subset according to the user identifier configured by the network side through the RRC signaling and the number of the uplink control channel resources included in the uplink control channel resource set.
For example, the UE may select the uplink control channel resources for feeding back HARQ-ACKs from the corresponding subset according to the following formula:
n represents the nth UE in the user group, and n is an integer greater than or equal to 1;
k represents the bit number occupied by the uplink control channel resource indication information, and k is an integer greater than or equal to 1;
idnrepresenting the user identification corresponding to the nth UE;
and T represents the number of the uplink control channel resources contained in the uplink control channel resource set.
If the user identifier is an RNTI configured by the network side through RRC signaling, the UE may determine the uplink control channel resource for feeding back the HARQ-ACK by itself in the corresponding subset according to the RNTI, and specifically, the UE may determine the uplink control channel resource for feeding back the HARQ-ACK by itself according to the following formula:wherein n isRNTIAnd indicates an RNTI corresponding to the UE.
If the user identifier is an intra-group identifier of the UE in the user group configured by the network side through RRC signaling, the UE may determine the uplink control channel resource for feeding back the HARQ-ACK by itself in the corresponding subset according to the intra-group identifier in the user group, and specifically, the UE may determine the uplink control channel resource for feeding back the HARQ-ACK by itself according to the following formula:
after the UE determines the resource identifier of the HARQ-ACK in the uplink control channel resource set, the HARQ-ACK may be fed back on the corresponding resource according to the determined resource identifier.
In specific implementation, whether the downlink control signaling includes the uplink control channel resource indication information bit may be configured through RRC signaling, and a PUCCH resource set available to the UE may also be configured through RRC signaling, where the PUCCH resource set includes multiple PUCCH resources.
In specific implementation, when receiving a downlink control signaling that a user indicates at least one user uplink data transmission and is sent by a network side, the UE may implement the resource indication method provided in the embodiment of the present invention according to the flow shown in fig. 3, including the following steps:
s31, the UE receives a downlink control signaling sent by the network side for indicating at least one user to transmit uplink data.
S32, UE determines the uplink shared channel resource for sending uplink data from the uplink resource scheduled by the downlink control signaling according to the user identification configured by the network side at least.
In specific implementation, the user identifier includes at least one of the following: the Radio Network Temporary Identifier (RNTI) corresponding to the UE and the user group identifier corresponding to the UE are identified, and the user identifier can be configured for the UE by a base station through RRC signaling.
In step S32, the UE may divide the uplink resource scheduled by the downlink control signaling into a plurality of subsets; the UE determines a subset identifier corresponding to the UE according to a user identifier configured on a network side; and determining the uplink shared channel resource for sending the uplink data according to the determined subset identifier.
